Detailed Description

[ description of embodiments of the present disclosure ]

First, embodiments of the present disclosure will be described.

(1) The disclosed connector for a substrate is provided with:

a housing that can be provided on a mounting surface of a substrate;

a plurality of terminal fittings held in parallel in the width direction with respect to the housing and connectable to the substrate;

a substrate-facing surface that constitutes an outer surface of the housing and is capable of facing the mounting surface;

a pair of first supporting portions formed on the substrate-facing surface; and

a second supporting portion formed on the opposite surface for substrate,

the pair of first supporting parts are arranged with an interval along the width direction,

the one second support portion is disposed at a position sandwiched by the pair of first support portions in the width direction and at a position different from the pair of first support portions in a direction intersecting with the width direction,

the case may be provided on the substrate in a state where only the pair of first supporting portions and the one second supporting portion are in contact with the mounting surface.

According to the configuration of the first publication, the housing is provided on the substrate in a state where only the pair of first supporting portions and the one second supporting portion are in contact with the mounting surface. The pair of first supporting portions are arranged with a gap therebetween in the width direction. One second support portion is disposed at a position sandwiched by the pair of first support portions in the width direction, and is disposed at a position different from the pair of first support portions in a direction intersecting with the width direction. Therefore, there is no possibility that the posture of the housing is inclined with respect to the substrate.

(2) Preferably, a metal fixing member is press-fitted into the housing in a direction approaching the mounting surface, and the fixing member is fixed to the mounting surface to restrict the housing from being detached from the board. According to this configuration, the metal fixing member is fixed to the mounting surface by brazing, whereby the case can be reliably prevented from coming off the substrate. Further, the housing does not tilt with respect to the substrate even if it is pressed toward the substrate side, and therefore there is no possibility that the housing is detached from the fixing member due to the tilting of the housing.

(3) In (2), the fixing member may have a leg portion that can be inserted into the through hole of the substrate, and the leg portion may be fixed to the substrate by brazing. According to this configuration, the leg portions are inserted into the through holes, whereby the case can be prevented from being displaced in a direction parallel to the mounting surface with respect to the substrate. When the housing approaches the mounting surface side while being tilted by an external force or the like, the leg portion of the fixing member press-fitted into the housing may be relatively displaced with respect to the substrate. However, since the housing does not incline in posture with respect to the substrate, the leg portion does not displace relative to the substrate and is held in a fixed state with respect to the substrate.

(4) The housing preferably has a fitting portion for fitting the mating connector in a direction orthogonal to the mounting surface. According to this configuration, when the mating connector is fitted to the fitting portion of the housing, the housing is pressed toward the mounting surface by the fitting force applied from the mating connector. Since the housing is restricted in inclination with respect to the substrate by the pair of first support portions and the one second support portion, the fitting operation is not hindered by the inclination of the attitude of the housing.

[ details of embodiments of the present disclosure ]

[ example 1]

Embodiment 1 of the substrate connector a according to the present disclosure will be described with reference to fig. 1 to 5. In this embodiment 1, the left side in fig. 1, 2, and 4 is defined as the front side with respect to the front-rear direction. The vertical direction is defined as the upper and lower directions as they are (with the substrate 40 horizontal and the mounting surface 41 of the substrate 40 facing upward, and with the substrate connector a provided on the mounting surface 41) shown in fig. 1 and 3 to 5. The directions indicated in fig. 1 and 3 are directly defined as the left and right directions. The left-right direction and the width direction are used synonymously.

As shown in fig. 1 to 3, the board connector a includes a housing 10, a plurality of terminal fittings 25, and a pair of left and right fixing members 30. The case 10 is made of synthetic resin and has a rectangular shape with the long side facing the width direction as a whole. The housing 10 is a single member and includes a terminal holding portion 11 whose long side faces in the width direction and a hood-shaped fitting portion 12 projecting upward in a square cylindrical shape from the entire peripheral region of the outer peripheral edge of the terminal holding portion 11.

As shown in fig. 3 to 5, the board is fixed to a mounting surface 41 (front surface) of the board 40 by a connector a. A printed circuit (not shown) is provided on the mounting surface 41. The substrate 40 has a plurality of through holes 42 penetrating from the mounting surface 41 to the back surface. As shown in fig. 3, the plurality of through holes 42 are arranged in 2 regions spaced apart in the width direction (left-right direction). In each region, the plurality of through holes 42 are arranged at intervals in the front-rear direction. The leg 32 of the fixing member 30 is inserted into each through hole 42.

As shown in fig. 1 and 5, the plurality of terminal fittings 25 are formed by bending an elongated metal member. Each terminal fitting 25 has a wire harness connection portion 26 extending in the vertical direction (direction perpendicular to the mounting surface 41) and a board connection portion 27 extending forward or rearward from a lower end portion of the wire harness connection portion 26. The terminal fitting 25 has a substantially L-shaped side view. The terminal fitting 25 is attached to the housing 10 in a state where the wire harness connection portion 26 penetrates the terminal holding portion 11 from below the housing 10. In a state where the terminal fitting 25 is attached to the housing 10, the connection portion 26 for a wire harness is housed in the fitting portion 12 in a manner projecting upward.

As shown in fig. 2 and 5, the plurality of terminal fittings 25 mounted on the housing 10 are arranged in front and rear rows. The plurality of terminal fittings 25 constituting the front row are arranged such that the wire harness connection portions 26 are aligned in a row in the width direction, and the substrate connection portions 27 are held in the housing 10 in a state of protruding forward. The plurality of terminal fittings 25 constituting the rear row are arranged such that the harness connecting portions 26 are aligned in a row in the width direction, and are held by the housing 10 in a state where the substrate connecting portions 27 protrude rearward.

As shown in fig. 2 and 3, the lower surface of the terminal holding portion 11 on the outer surface of the housing 10 serves as a substrate opposing surface 13. The board opposing surface 13 is a surface that faces parallel to the mounting surface 41 in a state where the board connector a (housing 10) is mounted on the board 40. In the substrate opposing surface 13, elongated rib- like holding portions 14F and 14R are formed in the width direction at portions that penetrate the harness connecting portion 26 in a bottom view. Rib- like holding portions 14F and 14R protrude downward (mounting surface 41 side) from substrate opposing surface 13. The rib-like holding portions 14F for the front row are arranged in series at intervals in the width direction. The rib-like holding portions 14R for the rear row are also arranged in a row at intervals in the width direction.

As shown in fig. 1 to 3, the case 10 has a pair of side wall portions 15 protruding downward (mounting surface 41 side) from both widthwise end edges of the substrate opposing surface 13. The pair of side wall portions 15 protrude downward from the substrate opposing surface 13. As shown in fig. 3, the protruding dimension of the side wall portion 15 from the substrate opposing surface 13 is larger than the protruding dimension of the rib- like holding portions 14F and 14R from the substrate opposing surface 13.

As shown in fig. 1, 2, 4, and 5, a pair of first supporting portions 16 are formed at the rear end portions of the pair of side wall portions 15 in bilateral symmetry. The pair of first supporting portions 16 are disposed at both ends of the housing 10 (the substrate opposing surface 13) in the width direction in a spaced-apart relationship in the width direction. The pair of first supporting portions 16 are arranged at two positions across the entire arrangement region of the plurality of terminal fittings 25 in the width direction. The pair of first support portions 16 are disposed rearward of the harness connection portions 26 of the terminal fittings 25 in the rear row (rib-shaped holding portions 14R in the rear row) in the front-rear direction (direction intersecting the width direction).

As shown in fig. 4 and 5, the first support portion 16 is shaped to project downward (toward the mounting surface 41) in a stepped manner with respect to an area of the side wall portion 15 forward of the first support portion 16. The lower end surface (protruding end surface) of the first support portion 16 is a first support surface 17 formed of a flat surface. As shown in fig. 2, the first support surface 17 is square when the housing 10 is viewed from the lower side (the substrate 40 side). As shown in fig. 3 to 5, in a state where the board facing surface 13 is opposed to the mounting surface 41 in parallel, the first support surface 17 is lower than the lower surfaces of the rib- like holding portions 14F and 14R and is slightly lower than the lower surface of the board connecting portion 27.

As shown in fig. 1 to 3, the housing 10 has a second support portion 18 projecting downward (mounting surface 41 side) from the substrate opposing surface 13. The number of second support portions 18 is only 1. The lower end surface (protruding end surface) of the second support portion 18 is a second support surface 19 formed of a flat surface. As shown in fig. 2, the second support surface 19 is square when the housing 10 is viewed from the lower side (the substrate 40 side). As shown in fig. 3 to 5, the second support surface 19 has the same height as the pair of first support surfaces 17 in a state where the substrate opposing surface 13 is opposed to the mounting surface 41 in parallel. That is, the height of the second support surface 19 is lower than the lower surfaces of the rib- like holding portions 14F and 14R, and is slightly lower than the lower surface of the substrate connecting portion 27.

As shown in fig. 2, the second support portion 18 (second support surface 19) is positioned between the rib-like holding portions 14F on the 2 leading rows in the width direction so as to be sandwiched between the pair of first support portions 16. The rear end of the second support portion 18 is located at a position overlapping with the wire harness connection portion 26 of the front row terminal fitting 25 (rib-like holding portion 14F for the front row) in the front-rear direction. The entire second support surface 19 is located forward of the harness connection portion 26 (rib-shaped holding portion 14F for the front row) of the front row terminal fitting 25 in the front-rear direction.

As shown in fig. 1, 4, and 5, a pair of front and rear groove-like press-fitting portions 20 extending in the vertical direction are formed on both outer side surfaces of the housing 10 in the width direction. The pair of groove-like press-fitting portions 20 are arranged at a distance in the front-rear direction and face each other so as to open toward the other side. The upper end of the groove-like press-fitting portion 20 is opened upward. As shown in fig. 5, a stopper 21 facing upward is formed in the groove-shaped press-fitting portion 20.

The pair of fixing members 30 are formed by bending a metal plate material. As shown in fig. 4 and 5, the fixing member 30 is a single member, and includes a main body 31 having a flat plate shape and a plurality of legs 32 projecting downward from a lower end edge of the main body 31. The plurality of leg portions 32 are arranged at intervals in the front-rear direction. The protruding direction of the leg portion 32 from the main body portion 31 is the same direction as the assembling direction of the fixing member 30 with respect to the housing 10. The fixing member 30 is assembled to the housing 10 by press-fitting the front and rear side edges of the body 31 into the groove-like press-fitting portions 20 from above the housing 10. The mounting direction of the fixing member 30 to the housing 10 is the same direction as the opposing direction of the board opposing surface 13 to the mounting surface 41 in the state where the board connector a is mounted on the board 40.

When the fixing member 30 is assembled to the correct position with respect to the housing 10, a pair of front and rear protruding portions 33 formed at the upper end portion of the main body portion 31 abut against the stoppers 21. Thereby, the fixing member 30 is positioned in the up-down direction with respect to the housing 10. In a state where the fixing member 30 is assembled to the housing 10, the plurality of leg portions 32 protrude downward from the lower end surfaces of the pair of side wall portions 15. The leg portion 32 is disposed in a region forward of the first support portion 16. The lower end (projecting end) of the leg 32 is located below the first support surface 17, the second support surface 19, and the substrate connecting portion 27.

When the board connector a is mounted on the board 40, the leg portion 32 of the fixing member 30 is inserted into the through hole 42 from above the board 40, and the pair of first supporting surfaces 17 and 1 second supporting surface 19 are placed on the mounting surface 41 in a surface contact state. At this time, of the opposing surface (substrate opposing surface 13) of the case 10 opposing the substrate 40, only the pair of first supporting portions 16 (first supporting surface 17) and the 1 second supporting portion 18 (second supporting surface 19) in contact with the mounting surface 41. In a state where the first support portion 16 and the second support portion 18 are placed on the mounting surface 41, the lower surface of the board connection portion 27 is slightly spaced from the mounting surface 41.

Next, the leg portion 32 inserted into the through hole 42 is fixed to the substrate 40 by the brazing 35, thereby fixing the fixing member 30 to the substrate 40. By inserting the leg portion 32 into the through hole 42, the case 10 is restricted from being displaced in a direction parallel to the mounting surface 41 with respect to the substrate 40. Before or after the step of fixing the fixing member 30 to the substrate 40, the substrate connection portion 27 is conductively connected to the printed circuit on the mounting surface 41 by the solder 35. During the brazing 35 step described above, the pair of first supporting portions 16 and the 1 second supporting portion 18 are held in surface contact with the mounting surface 41. When the step of soldering 35 is completed, the mounting of the board connector a to the board 40 is completed.

The board connector a of embodiment 1 includes 1 housing 10 and a plurality of terminal fittings 25. The housing 10 can be provided on the mounting surface 41 of the substrate 40. Each of the plurality of terminal fittings 25 has a substrate connection portion 27 connectable to the substrate 40. The plurality of terminal fittings 25 are held in a state of being juxtaposed in the width direction with respect to the housing 10. The plurality of substrate connection portions 27 are also arranged in the width direction.

The board connector a has a board opposing surface 13 constituting an outer surface of the housing 10. That is, a part of the outer surface of the case 10 serves as the substrate facing surface 13. The board opposing surface 13 can oppose the mounting surface 41, and is parallel to the mounting surface 41 in a state where the board connector a (housing 10) is mounted on the board 40.

A pair of first supporting portions 16 and 1 second supporting portion 18 are formed on the substrate opposing surface 13. The pair of first supporting portions 16 are disposed at two positions spaced apart in the width direction. The 1 second support portion 18 is disposed at a position sandwiched between the pair of first support portions 16 in the width direction. The 1 second support portion 18 is disposed at a position different from the pair of first support portions 16 (a position offset forward from the first support portions 16) in the front-rear direction intersecting the width direction. In the formation region of the substrate opposing surface 13, only the pair of first supporting portions 16 and 1 second supporting portion 18 of the case 10 (substrate opposing surface 13) protrude to the outermost surface side.

Therefore, the case 10 can be set on the substrate 40 in a state where only the pair of first support portions 16 (first support surfaces 17) and 1 second support portion 18 (second support surface 19) are brought into contact with the mounting surface 41. In a state where only the pair of first support portions 16 (first support surfaces 17) and 1 second support portion 18 (second support surface 19) are in contact with the mounting surface 41, even if an external force in a direction pressing toward the substrate 40 (mounting surface 41) side acts on the housing 10, the posture of the housing 10 does not tilt with respect to the substrate 40 (mounting surface 41). Therefore, the load on the portion where the fixing member 30 assembled to the housing 10 and the substrate 40 are brazed 35 is not increased, or the load on the connecting portion (the portion where the brazing 35 is performed) of the terminal fitting 25 held by the housing 10 and the substrate 40 is not increased.

The metal fixing member 30 assembled to the housing 10 is fixed to the mounting surface 41 by brazing 35. The fixing member 30 is fixed to the mounting surface 41 by the brazing 35, whereby the case 10 can be reliably prevented from being detached from the substrate 40. Since the housing 10 is not inclined with respect to the substrate 40 even if it is pressed toward the substrate 40, there is no possibility that the housing 10 is separated from the fixing member 30 due to the inclination of the housing 10.

In the board connector a of example 1, the fixing member 30 is assembled to the housing 10 by press fitting. The mounting direction (press-fitting direction) of the fixing member 30 to the housing 10 is a direction approaching the mounting surface 41, in other words, a direction parallel to the opposing direction of the substrate opposing surface 13 to the mounting surface 41. Therefore, if the housing 10 is inclined so as to approach the mounting surface 41 side when an external force acts on the housing 10 in a direction pressing toward the mounting surface 41 side, the groove-like press-fitting portion 20 to which the fixing member 30 is assembled is deformed, and the housing 10 may be displaced relative to the fixing member 30. However, since the housing 10 is not inclined with respect to the mounting surface 41, the housing 10 and the fixing member 30 are not relatively displaced, thereby maintaining the assembled state of the housing 10 and the fixing member 30.

When the housing 10 approaches the mounting surface 41 side while being tilted by external force or the like, the leg 32 of the fixing member 30 press-fitted into the housing 10 may be displaced relative to the substrate 40. However, since the housing 10 does not incline in posture with respect to the substrate 40, the leg 32 does not displace relative to the substrate 40. Therefore, the fixing member 30 (the leg portion 32) is held in a fixed state with respect to the substrate 40.

The housing 10 includes a fitting portion 12, and the fitting portion 12 is used for fitting a mating connector B (see fig. 4) in a direction perpendicular to the mounting surface 41 from the side (upper side) opposite to the mounting surface 41. When the mating connector is fitted to the fitting portion 12 of the housing 10, the housing 10 is pressed toward the mounting surface 41 by a fitting force applied from the mating connector. Since the housing 10 is restricted in inclination with respect to the substrate 40 by the pair of first supporting portions 16 and the 1 second supporting portion 18, the fitting operation is not hindered by the inclination of the posture of the housing 10.

The present invention is intended to include meanings equivalent to those of the present invention and all modifications within the scope of the present invention, and also includes embodiments as described below.

In embodiment 1 described above, the separation of the housing from the substrate is restricted by the fixing member, but the separation of the housing from the substrate may be restricted by directly engaging the housing with the substrate without using the fixing member.

In embodiment 1 described above, the mating connector is fitted to the housing from the side opposite to the mounting surface, but the fitting direction of the mating connector to the housing may be an orientation parallel to the mounting surface.

In example 1, the leg portions of the fixing member were inserted into the through holes of the substrate, but the fixing member may be soldered in a state of being mounted on the mounting surface.
