Technical Field

The present disclosure relates to a terminal block with an electronic component, which is obtained by mounting an electronic component on a terminal block in advance, an electronic device having the terminal block with the electronic component, and an electronic component mounting aid (hereinafter, also simply referred to as "mounting aid") interposed between the terminal block and the electronic component mounted on the terminal block.

Background

An I/O unit of a Programmable Logic Controller (PLC) has been known as an electronic device having a terminal block provided with a plurality of sets of common terminal connection portions each including a pair of terminal portions. The temperature input unit and the temperature adjustment unit (hereinafter referred to as "temperature measurement unit" including these units) in the I/O unit can measure the temperature using thermocouples connected to 1 or more of the plurality of sets of universal terminal connecting parts.

Here, when the temperature is measured using a thermocouple connected to a pair of terminal portions of the common terminal connection portion of the temperature measurement unit, a large deviation may occur between the measured temperature of the thermocouple and the temperature to be actually measured due to the influence of the terminal block temperature.

As a method for preventing the variation of the temperature measurement, the following methods are known: in order to measure the temperature of the terminal block of the temperature measuring unit, a cold contact sensor as an electronic component is mounted on the temperature measuring unit, and the temperature of the terminal block of the temperature measuring unit measured by the cold contact sensor is used to compensate for the deviation. As a document specifically disclosing such a method, for example, japanese patent laid-open No. 2004-150836 (patent document 1) is given.

In addition, although the above-mentioned publication describes that the cold contact sensor is provided in the temperature measuring unit located in the vicinity of the 1-group universal terminal connection portion to which the thermocouple is connected, it is not specifically mentioned at which position the cold contact sensor is provided.

Problems to be solved by the invention

As a method of installing the cold contact sensor, various methods are conceivable, and as one of them, the following method is considered: the cold contact sensor is mounted in advance to a specific 1-group universal terminal connection portion which is determined in advance or arbitrarily selected among a plurality of groups of universal terminal connection portions provided in the terminal block. In this method, a pair of lead wires of the cold contact sensor are inserted in advance into a pair of through holes of the terminal block provided corresponding to a pair of terminal portions of the 1-group specific universal terminal connecting portion, and the pair of lead wires are connected to the pair of terminal portions, whereby the cold contact sensor is mounted in advance on the terminal block.

In the case of such a configuration, the 1 group of the plurality of universal terminal connection portions provided in the terminal block can no longer be used as the universal terminal connection portion, but on the other hand, not only an effect that the cold contact sensor can be easily attached to the terminal block but also an effect that the component main body of the cold contact sensor can be provided outside the temperature measuring unit can be obtained, and therefore, the temperatures of the pair of terminal portions of the universal terminal connection portion can be more accurately measured, and as a result, the temperature measuring unit is less susceptible to internal heat generation of the temperature measuring unit, and an effect that a decrease in the accuracy of temperature measurement can be more reliably prevented can be obtained.

However, the common terminal connecting portion includes the pair of through holes and the pair of terminal portions so as to be able to receive terminals of various shapes and sizes, and thus the size thereof is relatively large, whereas the pair of lead wires of the cold contact sensor has a very thin shape. Therefore, when the cold contact sensor is externally attached to the universal terminal connecting portion, the attachment state is liable to become unstable, and when an external force is applied to the cold contact sensor, the terminal block, the temperature measuring unit, or the like, there is a possibility that a connection failure of the cold contact sensor may occur.

The present disclosure has been made in view of the above problems, and an object of the present disclosure is to provide a terminal block with an electronic component and an electronic apparatus having the terminal block with the electronic component, in which a mounting state of the electronic component to the terminal block is stabilized, and further, another object of the present disclosure is to provide a mounting aid for an electronic component, which can stabilize the mounting state when the electronic component is mounted to the terminal block.

Means for solving the problems

A terminal block with an electronic component according to one aspect of the present disclosure includes: a terminal block; an electronic component mounted on the terminal block; and an insulating mounting auxiliary member interposed between the electronic component and the terminal block. The terminal block includes: a housing having a 1 st through hole and a 2 nd through hole formed in a front wall thereof so as to reach a housing portion formed therein; a 1 st terminal portion disposed in the housing portion so as to face the 1 st through hole; and a 2 nd terminal portion disposed in the housing portion so as to face the 2 nd through hole. The electronic component includes: a component main body disposed outside the housing so as to face the front wall; a 1 st lead inserted through the 1 st through hole and connected to the 1 st terminal portion; and a 2 nd lead inserted into the 2 nd through hole and connected to the 2 nd terminal portion. The above-mentioned installation auxiliary member includes: a base portion having a back surface abutting against the front wall and disposed outside the housing so that a part of the base portion faces the 1 st through hole and the 2 nd through hole; a 1 st insertion portion that protrudes from a rear surface of the base portion and is inserted into the 1 st through hole; and a 2 nd insertion portion which is inserted into the 2 nd through hole by protruding from a back surface of the base portion. In the terminal block with an electronic component according to the above aspect of the present disclosure, the hollow 1 st passage portion into which the 1 st lead is inserted is provided across the base portion and the 1 st insertion portion, the hollow 2 nd passage portion into which the 2 nd lead is inserted is provided across the base portion and the 2 nd insertion portion, and the receiving portion that receives and accommodates at least the back portion of the component main body is provided at a position on the front surface side of the base portion.

With this configuration, the 1 st insertion portion and the 2 nd insertion portion of the mounting aid for electronic components are respectively present between the 1 st through hole provided in the front wall of the housing of the terminal block and the 1 st lead of the electronic component, and between the 2 nd through hole provided in the front wall of the housing of the terminal block and the 2 nd lead of the electronic component, so that the mounting state of the electronic component to the terminal block is stabilized. Further, since the receiving portion for receiving and housing at least the back portion of the component main body of the electronic component is provided at the position on the front surface side of the mounting aid for the electronic component, not only the mounting state of the electronic component is stabilized, but also the electronic component and the mounting aid for the electronic component are not arranged so as to protrude greatly at the position on the front surface side of the terminal block, and therefore, it is possible to avoid the electronic component and the mounting aid for the electronic component from causing an obstacle.

In the terminal block with an electronic component according to the above aspect of the present disclosure, it is preferable that the receiving portion is located at least between the 1 st passage portion and the 2 nd passage portion.

With this configuration, since the electronic component in a state in which at least the back portion thereof is accommodated in the receiving portion is arranged between the 1 st through hole and the 2 nd through hole at the position on the front surface side of the terminal block, the electronic component and the mounting aid for the electronic component are not arranged so as to greatly protrude outward from the region on the front surface side of the terminal block where the 1 st through hole and the 2 nd through hole are provided, and it is possible to further avoid the electronic component and the mounting aid for the electronic component from causing an obstacle.

In the terminal block with an electronic component according to the above aspect of the present disclosure, it is preferable that the base portion has a pair of opposing wall portions that face in a direction perpendicular to a direction in which the 1 st passage portion and the 2 nd passage portion are connected when viewed from the front side, and in this case, the receiving portion is defined by the pair of opposing wall portions.

With this configuration, the component main body of the electronic component can be sandwiched by the one opposing wall portion at the position on the front surface side of the terminal block in the direction perpendicular to the direction connecting the 1 st passage portion and the 2 nd passage portion, and therefore the component main body of the electronic component can be received and housed more stably by the receiving portion.

In the terminal block with an electronic component according to the above aspect of the present disclosure, it is preferable that the base portion is not located between the pair of wall portions when viewed from the front side.

With this configuration, since the mounting aid for electronic components is not located between the component main body of the electronic component housed in the receiving portion and the front wall of the terminal block, the amount of protrusion of the electronic component and the mounting aid for electronic components can be minimized at the position on the front side of the terminal block, and the electronic component and the mounting aid for electronic components can be prevented from interfering with each other to the maximum extent.

In the terminal block with an electronic component according to the above aspect of the present disclosure, it is preferable that the 1 st via portion has a 1 st guide portion, and a via cross-sectional area of the 1 st guide portion decreases as it is farther from the base portion, so that the 1 st lead is guided to the 1 st terminal portion, and the 2 nd via portion has a 2 nd guide portion, and a via cross-sectional area of the 2 nd guide portion decreases as it is farther from the base portion, so that the 2 nd lead is guided to the 2 nd terminal portion.

With this configuration, when the electronic component is mounted on the terminal block, the 1 st lead and the 2 nd lead of the electronic component are guided by the 1 st guiding portion and the 2 nd guiding portion and connected to the 1 st terminal portion and the 2 nd terminal portion, respectively, so that the connection position can be made appropriate and the mounting work can be facilitated, and in a state after mounting, the 1 st lead and the 2 nd lead can be prevented from being displaced in a direction perpendicular to the respective connection directions thereof, and as a result, occurrence of a connection failure can be prevented.

In the terminal block with an electronic component according to the above aspect of the present disclosure, it is preferable that a 1 st frame-shaped portion surrounding at least a part of the 1 st passage portion be provided in the base portion when viewed from the front side, and a 2 nd frame-shaped portion surrounding at least a part of the 2 nd passage portion be provided in the base portion when viewed from the front side. In this case, the back surface of the 1 st frame-shaped portion and the back surface of the 2 nd frame-shaped portion are in contact with the front wall, respectively.

With this configuration, the mounting aid for the electronic component interposed between the electronic component and the terminal block is stably positioned and held with respect to the terminal block, and as a result, the mounting state of the electronic component with respect to the terminal block can be further stabilized.

An electronic device according to one aspect of the present disclosure includes a terminal block with an electronic component according to one aspect of the present disclosure.

With this configuration, the electronic component can be stably mounted on the terminal block.

An electronic component mounting aid according to an aspect of the present disclosure is interposed between an electronic component mounted on a terminal block and the terminal block, the electronic component mounting aid including: a base, which is used in the following manner: the back surface of the base part is abutted against the front wall of the shell of the terminal block, and the base part is configured outside the shell of the terminal block in a mode that part of the base part faces the 1 st through hole and the 2 nd through hole of the terminal block; 1 st insertion part, which is used in the following way: a 1 st through hole protruding from the back surface of the base and inserted into the terminal block; and a 2 nd insertion portion, which is used in the following manner: the second through hole is inserted into the 2 nd through hole of the terminal block by protruding from the back surface of the base. In the mounting aid according to the above-described one aspect of the present disclosure, the hollow 1 st passage portion into which the 1 st lead of the electronic component is inserted is provided across the base portion and the 1 st insertion portion, the hollow 2 nd passage portion into which the 2 nd lead of the electronic component is inserted is provided across the base portion and the 2 nd insertion portion, and the receiving portion that receives and receives at least the back portion of the component main body of the electronic component is provided at a position on the front surface side of the base portion.

With this configuration, it is possible to form the mounting aid for electronic components, which can stabilize the mounting state when the electronic components are mounted on the terminal block.

Fig. 3 is an exploded perspective view of a main part of the terminal block shown in fig. 2. First, the electronic device 1 according to the embodiment and the schematic structure of the terminal block 3 with electronic components provided therein will be described with reference to fig. 1 to 3.

As shown in fig. 1, an electronic device 1 as a temperature measuring unit of a PLC has a flat substantially rectangular parallelepiped shape having a relatively large vertical and longitudinal external dimensions and a relatively small horizontal external dimension, and includes a device main body 2 and a terminal block 3 with electronic components. The terminal block 3 with the electronic component is attached to a notched portion provided at the lower portion of the front surface side of the device main body 2, whereby the electronic device 1 as a whole has a substantially rectangular parallelepiped shape as described above.

Various electronic components, a wiring board on which the various electronic components are mounted, and the like are housed in the device main body 2, and these components constitute functional portions of the electronic device 1 necessary for temperature measurement, temperature adjustment, and the like. On the other hand, the terminal block 3 with electronic components constitutes an input/output unit for electrically connecting these functional units provided inside the device main body 2 to external devices, sensors (including thermocouples), and the like.

As shown in fig. 1 to 3, the terminal block 3 with electronic components includes a terminal block 10, a mounting aid 100A, and an electronic component 200. Among them, the electronic component 200 is a so-called cold contact sensor, and is externally mounted on the terminal block 10. The mounting aid 100A is interposed between the electronic component 200 mounted on the terminal block 10 and the terminal block 10.

The terminal block 10 has an elongated substantially rectangular parallelepiped shape extending in the vertical direction, and has a plurality of sets of common terminal connection portions to which thermocouples and the like can be connected on the front surface thereof. The electronic component 200 is connected to the common terminal connecting portion located on the uppermost layer among the plurality of sets of common terminal connecting portions from the outside of the terminal block 10. The mounting aid 100A is mounted to the universal terminal connecting portion on which the electronic component 200 is mounted, and is interposed between the electronic component 200 and the terminal block 10.

In the present embodiment, the case where the electronic component 200 is mounted on the common terminal connecting portion located at the uppermost layer among the plurality of sets of common terminal connecting portions is described as an example, but it is needless to say that the electronic component may be mounted on another common terminal connecting portion.

The terminal block 10 has a case 11 as an outer shell of the terminal block 10, and the case 11 includes a front wall 12. The front wall 12 is provided with a plurality of through holes and a plurality of windows in a matrix shape. The plurality of through holes and the plurality of window portions constitute a plurality of sets of common terminal connecting portions. Here, the pair of common terminal connecting portions includes a pair of left and right through holes (the 1 st through hole 13R and the 2 nd through hole 13L) and a pair of left and right window portions (the 1 st window portion 14R for operation and the 2 nd window portion 14L for operation).

The 1 st through hole 13R and the 2 nd through hole 13L are each formed of a substantially cylindrical hole portion provided in the front wall 12, and each penetrate the front wall 12 along the thickness direction of the front wall 12. On the other hand, the operation 1 st window portion 14R and the operation 2 nd window portion 14L are each constituted by a substantially quadrangular prism-shaped hole portion provided in the front face wall 12, and both penetrate through the front face wall 12 along the thickness direction of the front face wall 12. The 1 st window 14R for operation is positioned above the 1 st through hole 13R, and the 2 nd window 14L for operation is positioned above the 2 nd through hole 13L.

Referring to fig. 3 in particular, the electronic component 200 includes a component main body 210, a pair of left and right lead wires (1 st lead wire 211R and 2 nd lead wire 211L), and a cylindrical cover member 220 covering the component main body 210.

The component body 210 has a substantially cylindrical outer shape, and the 1 st lead 211R and the 2 nd lead 211L extend from the axial end face of the component body 210 in opposite directions to each other in the axial direction of the component body 210, respectively. The 1 st lead 211R and the 2 nd lead 211L are bent at intermediate positions thereof, and portions thereof on the tip side extend in the same direction. The cover member 220 is a member for protecting the member main body 210 from the outside, and is also a member for insulating the member main body 210 from the outside air.

With particular reference to fig. 3, the mounting aid 100A is formed of an insulative member, preferably a resin injection-molded article, including a base portion 110 positioned on the front side and a pair of left and right insertion portions (a 1 st insertion portion 120R and a 2 nd insertion portion 120L) projecting rearward from the rear surface of the base portion 110. The material of the mounting aid 100A is not particularly limited as long as it is insulating, and a particularly preferable material is, for example, polycarbonate resin.

The base portion 110 is configured to have a relatively large outer dimension in the left-right direction and a relatively small outer dimension in the up-down direction, and is configured to have a flat frame-shaped portion having a sufficiently small outer dimension in the front-back direction and a cut-away central portion. On the other hand, the 1 st insertion portion 120R and the 2 nd insertion portion 120L are each formed by a tubular portion extending in the front-rear direction.

As a specific structure thereof, which will be described in detail later, in the attachment auxiliary 100A, a hollow 1 st passage portion 121R is provided across the base portion 110 and the 1 st insertion portion 120R, and a hollow 2 nd passage portion 121L is provided across the base portion 110 and the 2 nd insertion portion 120L. The base portion 110 of the attachment auxiliary 100A is provided with a notch-shaped receiving portion 113 at a position on the front surface side thereof.

Here, referring to fig. 1 to 3, in the terminal block 3 with an electronic component, the mounting aid 100A is mounted to the common terminal connecting portion located at the uppermost layer of the terminal block 10 by inserting the 1 st insertion portion 120R of the mounting aid 100A into the 1 st through hole 13R of the terminal block 10 and inserting the 2 nd insertion portion 120L of the mounting aid 100A into the 2 nd through hole 13L of the terminal block 10.

On the other hand, the electronic component 200 is mounted to the common terminal connection portion located at the uppermost layer of the terminal block 10 in a state where the 1 st lead wire 211R is inserted through the 1 st passage portion 121R of the mounting aid 100A and the 2 nd lead wire 211L is inserted through the 2 nd passage portion 121L of the mounting aid 100A. The back of the component body 210 of the electronic component 200 and the cover member 220 covering the component body 210 are housed in the receiving portion 113 provided in the base portion 110 of the attachment assistant 100A.

Detailed construction of installation aid

Fig. 4 and 5 are a perspective view and a front view of the installation assistant of the embodiment, respectively. Fig. 6 is a sectional view taken along line VI-VI in fig. 5, and fig. 7 is a sectional view taken along line VII-VII in fig. 6. Next, a more detailed structure of the attachment auxiliary 100A of the embodiment will be described with reference to fig. 4 to 7.

As described above, as shown in fig. 4 to 7, the installation assistant fitting 100A has the base 110, the 1 st insertion portion 120R, and the 2 nd insertion portion 120L. The base 110 is a portion that abuts against the front wall 12 of the terminal block 10 in a state where the attachment auxiliary 100A is attached to the terminal block 10. On the other hand, the 1 st insertion portion 120R and the 2 nd insertion portion 120L are portions to be inserted into the 1 st through hole 13R and the 2 nd through hole 13L provided in the front wall 12 of the terminal block 10, respectively, in a state where the attachment auxiliary 100A is attached to the terminal block 10.

The base portion 110 includes a pair of wall portions (an upper standing wall portion 111U and a lower standing wall portion 111D) facing in the vertical direction (i.e., a direction perpendicular to a direction connecting the 1 st passage portion 121R and the 2 nd passage portion 121L when viewed from the front side), and a pair of frame-shaped portions (a 1 st frame-shaped portion 112R and a 2 nd frame-shaped portion 112L) located at both ends in the horizontal direction.

The upper standing wall portion 111U and the lower standing wall portion 111D extend in the left-right direction with respect to each other, and are located substantially between the 1 st insertion portion 120R and the 2 nd insertion portion 120L when viewed from the front.

These upper standing wall portion 111U and lower standing wall portion 111D are portions that come into contact with front wall 12 of terminal block 10 in a state where auxiliary attachment 100A is attached to terminal block 10, and more specifically, the back surface of upper standing wall portion 111U and the back surface of lower standing wall portion 111D are in contact with front wall 12, respectively.

A receiving portion 113 defined by the upper standing wall portion 111U and the lower standing wall portion 111D is located between the upper standing wall portion 111U and the lower standing wall portion 111D. As described above, the receiving portion 113 is a portion for receiving and housing the cover member 220 of the electronic component 200 and the back of the component main body 210 covered therewith.

When viewed from the front, the base portion 110 is not positioned between the upper standing wall portion 111U and the lower standing wall portion 111D, and this portion penetrates in the front-rear direction. Here, in the present embodiment, a part of the 1 st insertion portion 120R and a part of the 2 nd insertion portion 120L are disposed at positions on the back side of the portion.

The 1 st frame portion 112R is formed of an arc-shaped portion connecting the right ends of the upper standing wall portion 111U and the lower standing wall portion 111D, and surrounds a 1 st passage portion 121R, which will be described later in detail, when viewed from the front side. The 2 nd frame-shaped portion 112L is formed of an arc-shaped portion connecting the left ends of the upper standing wall portion 111U and the lower standing wall portion 111D, and surrounds the 2 nd passage portion 121L, which will be described later in detail, when viewed from the front.

These 1 st frame-shaped portion 112R and 2 nd frame-shaped portion 112L are portions that abut against the front wall 12 of the terminal block 10 in a state where the attachment auxiliary 100A is attached to the terminal block 10, and more specifically, the back surface of the 1 st frame-shaped portion 112R and the back surface of the 2 nd frame-shaped portion 112L abut against the front wall 12, respectively.

The 1 st insertion portion 120R is formed of a tubular portion protruding rearward from a portion near the right end of the rear surface of the base portion 110, and includes a 1 st passage portion 121R through which the 1 st lead 211R of the electronic component 200 can be inserted. The 1 st passage portion 121R extends in the front-rear direction, and has open front and rear ends. Here, the front end side open end of the 1 st passage portion 121R is defined by the front side 1 st opening 114R provided in the right end side of the base portion 110, and the rear end side open end of the 1 st passage portion 121R is defined by the rear side 1 st opening 123R provided in the rear end of the 1 st insertion portion 120R.

The 1 st passage portion 121R is provided with a 1 st guide portion 122R whose passage cross-sectional area decreases as it goes away from the base portion 110 (i.e., as it goes from a portion on the front-side 1 st opening 114R side toward a portion on the back-side 1 st opening 123R side). The 1 st lead portion 122R is a portion for guiding the 1 st lead 211R to a 1 st terminal portion 16R (see fig. 8) described later when the 1 st lead 211R of the electronic component 200 is inserted into the 1 st passage portion 121R.

The 2 nd insertion portion 120L is formed of a tubular portion protruding rearward from a portion near the left end of the rear surface of the base portion 110, and includes a 2 nd passage portion 121L through which the 2 nd lead wire 211L of the electronic component 200 can be inserted. The 2 nd passage portion 121L extends in the front-rear direction, and the front end and the rear end thereof are open. Here, the front end side open end of the 2 nd passage portion 121L is defined by the front side 2 nd opening portion 114L provided near the left end of the base portion 110, and the rear end side open end of the 2 nd passage portion 121L is defined by the rear side 2 nd opening portion 123L provided at the rear end of the 2 nd insertion portion 120L.

The 2 nd passage part 121L is provided with a 2 nd guide part 122L whose passage cross-sectional area decreases as it goes away from the base 110 (i.e., as it goes from a portion on the front side 2 nd opening 114L side toward a portion on the rear side 2 nd opening 123L side). The 2 nd lead portion 122L is a portion for guiding the 2 nd lead wire 211L to a 2 nd terminal portion 16L (see fig. 8) described later when the 2 nd lead wire 211L of the electronic component 200 is inserted into the 2 nd passage portion 121L.

Here, the back-side 1 st opening 123R of the 1 st passage portion 121R and the back-side 2 nd opening 123L of the 2 nd passage portion 121L each have a vertically long hole shape having a relatively large vertical dimension and a relatively small horizontal dimension. With this configuration, the 1 st lead 211R and the 2 nd lead 211L of the electronic component 200 inserted through the 1 st via 121R and the 2 nd via 121L can be more precisely positioned in the left-right direction.

Mounting structure of electronic component to terminal block

Fig. 8 is a sectional view taken along line VIII-VIII shown in fig. 2, and fig. 9 is a sectional view taken along line IX-IX shown in fig. 8. Next, referring to fig. 8 and 9, a mounting structure of the electronic component 200 to the terminal block 10 in the terminal block 3 with an electronic component according to the embodiment will be described in more detail.

As shown in fig. 8 and 9, a housing 15 is provided inside the case 11 of the terminal block 10 and behind the front wall 12. The housing 15 includes a 1 st housing 15R located on the right side of the terminal block 10 and a 2 nd housing 15L located on the left side of the terminal block 10, the 1 st housing 15R being located behind the 1 st through hole 13R, and the 2 nd housing 15L being located behind the 2 nd through hole 13L. In other words, the 1 st through hole 13R is provided in the front wall 12 so as to reach the 1 st housing portion 15R provided in the housing 11, and the 2 nd through hole 13L is provided in the front wall 12 so as to reach the 2 nd housing portion 15L provided in the housing 11.

The 1 st terminal portion 16R is disposed in the 1 st receiving portion 15R so as to face the 1 st through hole 13R. On the other hand, the 2 nd terminal portion 16L is disposed in the 2 nd receiving portion 15L so as to face the 2 nd through hole 13L. These 1 st terminal portion 16R and 2 nd terminal portion 16L are portions to which the 1 st lead wire 211R and the 2 nd lead wire 211L of the electronic component 200 are connected, and are each constituted by a terminal main body 17 and a plate spring 18.

Here, the 1 st terminal portion 16R and the 2 nd terminal portion 16L include portions different in shape or the like in a strict sense, but since the basic structure is the same, the description of the structure will be made below with respect to the 1 st terminal portion 16R.

A part of the terminal main body 17 is disposed at a position on the lower side of the 1 st housing portion 15R provided inside the terminal block 10. On the other hand, the plate spring 18 is disposed at an upper position in the 1 st housing portion 15R provided in the terminal block 10 so as to face the terminal main body 17 disposed at a portion of the 1 st housing portion 15R located at the lower position. In the present embodiment, the terminal body 17 has a substantially U-shape in side view, and the plate spring 18 has a shape bent in a clip shape.

The tip of the plate spring 18 abuts against the terminal main body 17, and is elastically biased against the terminal main body 17 by its own elastic force. Here, the terminal body 17 is made of a conductive member having relatively high rigidity. On the other hand, the plate spring 18 is made of a member having a high elastic force, and may be made of a conductive member or a non-conductive member. The terminal main body 17 is electrically connected to a circuit board, not shown, at a position on the rear end side thereof.

Thus, the 1 st lead wire 211R of the electronic component 200 is inserted from the front between the terminal main body 17 constituting the 1 st terminal portion 16R and the plate spring 18 in the portion in contact therewith, and the 1 st lead wire 211R is sandwiched between the terminal main body 17 and the plate spring 18, whereby the 1 st lead wire 211R and the 1 st terminal portion 16R are connected.

Further, since the 2 nd terminal portion 16L also has substantially the same structure as the 1 st terminal portion 16R as described above, the 2 nd lead wire 211L of the electronic component 200 is inserted from the front between the terminal main body 17 constituting the 2 nd terminal portion 16L and the plate spring 18 in a portion in contact therewith, and the 2 nd lead wire 211L is sandwiched between the terminal main body 17 and the plate spring 18, whereby the 2 nd lead wire 211L and the 2 nd terminal portion 16L are connected.

Here, a predetermined portion of the plate spring 18 constituting the 1 st terminal portion 16R faces the 1 st window portion 14R for operation provided on the front wall 12 of the terminal block 10. A predetermined portion of the plate spring 18 constituting the 2 nd terminal portion 16L faces the 2 nd window portion 14L for operation provided on the front wall 12 of the terminal block 10.

Thus, by inserting a tool having a predetermined shape into the operation 1 st window portion 14R and the operation 2 nd window portion 14L, the tool can be brought into contact with the plate spring 18 to elastically deform the plate spring 18, and the contact of the plate spring 18 with the terminal main body 17 can be released. Therefore, by performing the above-described operation using this tool, the insertion and removal of the 1 st lead wire 211R into and from the 1 st terminal portion 16R and the insertion and removal of the 2 nd lead wire 211L into and from the 2 nd terminal portion 16L can be performed more easily.

As described above, the terminal block 3 with an electronic component according to the present embodiment is formed by mounting the electronic component 200 to the terminal block 10 with the mounting aid 100A interposed therebetween.

Specifically, as shown in fig. 8 and 9, the attachment auxiliary 100A is disposed outside the housing 11 such that the base portion 110 thereof abuts the front wall 12 of the terminal block 10 and a part thereof faces the 1 st through hole 13R and the 2 nd through hole 13L, the 1 st insertion portion 120R thereof is inserted into the 1 st through hole 13R provided in the front wall 12, and the 2 nd insertion portion 120L thereof is inserted into the 2 nd through hole 13L provided in the front wall 12.

The electronic component 200 is disposed outside the housing 11 such that the component body 210 faces the front wall 12 of the terminal block 10, and the 1 st lead wire 211R is inserted through the 1 st through hole 13R provided in the front wall 12 to be connected to the 1 st terminal portion 16R, and the 2 nd lead wire 211L is inserted through the 2 nd through hole 13L provided in the front wall 12 to be connected to the 2 nd terminal portion 16L.

Here, the cover member 220 of the electronic component 200 and the back of the component body 210 covered therewith are in a state of being received and housed by the receiving portion 113 provided to the base portion 110 of the mounting aid 100A, the 1 st lead 211R of the electronic component 200 is in a state of being inserted through the 1 st passage portion 121R provided astride the base portion 110 and the 1 st insertion portion 120R of the mounting aid 100A, and the 2 nd lead 211L of the electronic component 200 is in a state of being inserted through the 2 nd passage portion 121L provided astride the base portion 110 and the 2 nd insertion portion 120L of the mounting aid 100A.

With this configuration, the 1 st insertion portion 120R and the 2 nd insertion portion 120L of the mounting aid 100A are interposed between the 1 st through hole 13R provided in the front wall 12 of the terminal block 10 and the 1 st lead 211R of the electronic component 200, and between the 2 nd through hole 13L provided in the front wall 12 of the terminal block 10 and the 2 nd lead 211L of the electronic component 200, respectively, so that the mounting state of the electronic component 200 to the terminal block 10 is stabilized.

Further, since the cover member 220 for receiving and housing the electronic component 200 and the receiving portion 113 for receiving the back of the component main body 210 covered therewith are provided at the position on the front surface side of the mounting aid 100A, the mounting state of the electronic component 200 can be stabilized, and the electronic component 200 and the mounting aid 100A are not arranged so as to greatly protrude at the position on the front surface side of the terminal block 10, and therefore, it is possible to avoid the electronic component 200 and the mounting aid 100A from causing an obstacle.

Further, as the socket 113 is positioned between the 1 st passage portion 121R and the 2 nd passage portion 121L, the cover member 220 of the electronic component 200 with the back portion thereof received in the socket 113 and the component main body 210 covered therewith are disposed between the 1 st through hole 13R and the 2 nd through hole 13L at the position on the front surface side of the terminal block 10.

Therefore, with such a configuration, it is possible to avoid the electronic component 200 and the mounting aid 100A from protruding greatly outward (i.e., in the left-right direction, the vertical direction, and the like) from the region on the front surface side of the terminal block 10 where the 1 st through hole 13R and the 2 nd through hole 13L are provided, and it is possible to further avoid the electronic component 200 and the mounting aid 100A from causing an obstacle.

Further, since the receiving portion 113 is defined by the upper standing wall portion 111U and the lower standing wall portion 111D which are opposed to each other in the vertical direction, the cover member 220 of the electronic component 200 and the back portion of the component main body 210 covered therewith can be sandwiched in the vertical direction at a position on the front surface side of the terminal block 10, and therefore, the electronic component 200 can be received and stored more stably by the receiving portion 113.

Further, when viewed from the front side, since the base portion 110 is not located between the upper standing wall portion 111U and the lower standing wall portion 111D, the mounting aid 100A is not located between the back surface of the electronic component 200 housed in the receiving portion 113 and the front wall 12 of the terminal block 10, and therefore, the amount of projection of the electronic component 200 and the mounting aid 100A can be minimized at the position on the front side of the terminal block 10, and the electronic component 200 and the mounting aid 100A can be prevented from being hindered to the maximum extent.

Further, since base portion 110 is provided with not only upper standing wall portion 111U and lower standing wall portion 111D but also 1 st frame-shaped portion 112R and 2 nd frame-shaped portion 112L, the back surfaces of upper standing wall portion 111U, lower standing wall portion 111D, 1 st frame-shaped portion 112R, and 2 nd frame-shaped portion 112L are brought into contact with front surface wall 12 of terminal block 10, and mounting auxiliary 100A interposed between electronic component 200 and terminal block 10 is positioned and held more stably with respect to terminal block 10, and as a result, the mounting state of electronic component 200 with respect to terminal block 10 can be further stabilized.

Here, in the terminal block 3 with electronic components of the present embodiment, as described above, the 1 st guide portion 122R and the 2 nd guide portion 122L described above are provided in the 1 st passage portion 121R and the 2 nd passage portion 121L of the attachment assistant fitting 100A. Therefore, when the electronic component 200 is mounted on the terminal block 10, the 1 st lead wire 211R and the 2 nd lead wire 211L of the electronic component 200 are guided by the 1 st guide portion 122R and the 2 nd guide portion 122L and connected to the 1 st terminal portion 16R and the 2 nd terminal portion 16L, respectively, and the connection position can be optimized and the mounting operation can be facilitated. In addition, in the mounted state, the 1 st lead wire 211R and the 2 nd lead wire 211L can be prevented from being displaced in the direction perpendicular to the respective connecting directions (i.e., the left-right direction, the up-down direction, and the like), and as a result, the occurrence of a connection failure can be prevented.

Referring to fig. 8, when the distance a between the bent portions of the 1 st lead wire 211R and the 2 nd lead wire 211L provided in the electronic component 200 does not match the pitch B between the 1 st terminal portion 16R and the 2 nd terminal portion 16L, it is particularly preferable to provide the 1 st guide portion 122R and the 2 nd guide portion 122L described above in the mounting aid 100A. That is, when the electronic component 200 is mounted on the terminal block 10, the 1 st lead wire 211R and the 2 nd lead wire 211L are corrected in the directions thereof by the 1 st guide portion 122R and the 2 nd guide portion 122L, whereby the connection position of the 1 st lead wire 211R to the 1 st terminal portion 16R and the connection position of the 2 nd lead wire 211L to the 2 nd terminal portion 16L can be adjusted to desired positions, and occurrence of connection failure of the electronic component 200 can be greatly suppressed even when an external force is applied to the electronic component 200, the terminal block 10, the electronic device 100, and the like.

Here, in the example shown in fig. 8, a case is shown in which the distance a between the bent portions of the 1 st lead wire 211R and the 2 nd lead wire 211L provided in the electronic component 200 is larger than the pitch B between the 1 st terminal portion 16R and the 2 nd terminal portion 16L, and in this case, it is preferable that the pitch C between the 1 st opening portion 123R on the back surface side of the 1 st via portion 121R and the 2 nd opening portion 123L on the back surface side of the 2 nd via portion 121L is set smaller than the distance a and larger than the pitch B.

On the other hand, when the distance a between the bent portions of the 1 st lead wire 211R and the 2 nd lead wire 211L provided in the electronic component 200 is smaller than the pitch B between the 1 st terminal portion 16R and the 2 nd terminal portion 16L, the pitch C between the 1 st opening 123R on the back surface side of the 1 st via portion 121R and the 2 nd opening 123L on the back surface side of the 2 nd via portion 121L is preferably set to be larger than the distance a and smaller than the pitch B.

When the distance a between the bent portions of the 1 st lead wire 211R and the 2 nd lead wire 211L provided in the electronic component 200 is equal to the pitch B between the 1 st terminal portion 16R and the 2 nd terminal portion 16L, the pitch C between the 1 st opening 123R on the back surface side of the 1 st via portion 121R and the 2 nd opening 123L on the back surface side of the 2 nd via portion 121L is preferably set to be equal to the distance a and the pitch B.

That is, the above-described installation assistant 100A is preferably designed in the following manner: in the mounted state in which the electronic component 200 is mounted on the terminal block 10, if the mounting aid 100A is designed such that the back-side 1 st opening 123R is located on a line segment connecting the bent portion of the 1 st lead wire 211R and the connection target position of the 1 st terminal portion 16R and the 1 st lead wire 211R, and the back-side 2 nd opening 123L is located on a line segment connecting the bent portion of the 2 nd lead wire 211L and the connection target position of the 2 nd terminal portion 16L and the 2 nd lead wire 211L, it is possible to greatly suppress the occurrence of a connection failure of the electronic component 200.

Specifically, in the attachment auxiliary 100B, the 1 st frame-shaped portion 112R and the 2 nd frame-shaped portion 112L extending in the arc shape are configured to be longer, and accordingly, the upper standing wall portion 111U and the lower standing wall portion 111D are configured to be shorter and the distance therebetween is smaller, and the 1 st passage portion 121R and the 2 nd passage portion 121L are both formed such that the portions on the tip side thereof have a substantially cylindrical space and the portions on the rear end side thereof have a substantially truncated conical space.

In the case of such a configuration, basically, the same configuration as that of the above-described embodiment is adopted, and therefore, by providing the terminal block with the electronic component and the electronic device including the mounting aid 100B, the mounting state of the electronic component to the terminal block can be stabilized, and by using the mounting aid 100B, the mounting state of the electronic component can be stabilized when the electronic component is mounted on the terminal block.

The following describes the attachment auxiliary 100C according to modification 2 with reference to fig. 12 and 13. The auxiliary attachment 100C is used in the electronic device 1 and the terminal block 3 with electronic components provided in the electronic device 1, instead of the auxiliary attachment 100A of the above embodiment.

As shown in fig. 12 and 13, the mounting aid 100C of modification 2 is different in shape in the 1 st insertion portion 120R and the 2 nd insertion portion 120L when compared with the mounting aid 100B of modification 1. Specifically, in the attachment assistant fitting 100C, each of the 1 st passage portion 121R and the 2 nd passage portion 121L is formed such that a portion on the tip end side thereof has a substantially truncated conical space and a portion on the rear end side thereof has a substantially cylindrical space. Further, a 1 st rib 124R and a 2 nd rib 124L are provided on the outer peripheral surfaces of the 1 st insertion portion 120R and the 2 nd insertion portion 120L, respectively.

In the case of such a configuration, basically, the same configuration as that of the above-described embodiment is adopted, and therefore, by providing the terminal block with the electronic component and the electronic device including the mounting aid 100C, the mounting state of the electronic component to the terminal block can be stabilized, and by using the mounting aid 100C, the mounting state of the electronic component can be stabilized when the electronic component is mounted to the terminal block.

Fig. 14 and 15 are a perspective view and a cross-sectional view, respectively, of an attachment auxiliary according to modification 3 of the above embodiment. The following describes the attachment auxiliary 100D according to the modification 3 with reference to fig. 14 and 15. The mounting aid 100D is used in place of the mounting aid 100A of the above-described embodiment for the electronic device 1 and the terminal block 3 with electronic components provided in the electronic device 1.

As shown in fig. 14 and 15, the attachment assistant fitting 100D according to modification 3 is different in shape in the base portion 110, the 1 st insertion portion 120R, and the 2 nd insertion portion 120L, compared with the attachment assistant fitting 100B according to modification 1. Specifically, in the attachment auxiliary 100D, the 1 st frame-shaped portion 112R and the 2 nd frame-shaped portion 112L extending in an arc shape are cut out at predetermined positions, and the 1 st locking portion 125R and the 2 nd locking portion 125L are provided in the 1 st insertion portion 120R and the 2 nd insertion portion 120L, respectively.
