Technical Field

The present disclosure relates to connectors.

Background

Patent document 1 discloses a connector that supplies electric power to an in-vehicle device. The connector described in patent document 1 includes two cavities capable of accommodating two terminals. A lance portion is formed on an inner wall of the cavity, and the lance portion engages with a terminal inserted into the cavity. The terminal is inserted into the cavity and engaged with the lance portion, thereby being held by the housing and prevented from being detached from the housing.

Disclosure of Invention

Problems to be solved by the invention

In the connector 9 described in patent document 1, it is conceivable to use a terminal 91 as shown in fig. 10. One end side of the terminal 91 shown in fig. 10 is inserted into the cavity, and the other end side protrudes from the cavity to the outside of the housing 92. A connection portion 911 is formed at a projecting end of the terminal 91, and the connection portion 911 is formed to be widened so as to project toward both sides in the arrangement direction of the pair of terminals 91, and includes a bolt insertion portion 912. The terminal 91 is connected to another conductive member by a bolt inserted into the bolt insertion portion 912.

However, in the configuration shown in fig. 10, when the assembly accuracy of the pair of terminals 91 with respect to the housing 92 and the molding accuracy of the housing 92 are lowered, the connection portions 911 of the pair of terminals 91 may come too close to each other in the arrangement direction Y. In this case, there is room for improvement in terms of ensuring electrical insulation between the pair of terminals 91.

Here, when one terminal 91 is separated from the other terminal 91 in the arrangement direction Y, the gap between the pair of terminals 91 is increased, and insulation between the pair of terminals 91 can be ensured. However, the length from one end of one terminal 91 to the other end of the other terminal 91 in the arrangement direction Y increases, which leads to an increase in size of the connector 9. Further, it is also conceivable to secure the space between the pair of terminals 91 while suppressing an increase in size by reducing the width of each terminal 91 in the arrangement direction Y, but there is a possibility that the resistance value of the terminal 91 increases as the sectional area of each terminal 91 decreases.

The present disclosure has been made in view of the above problems, and provides a connector capable of ensuring electrical insulation between a pair of terminals while suppressing an increase in size and an increase in resistance value of the terminals.

Means for solving the problems

One aspect of the present disclosure is a connector including:

a housing; and

a first terminal and a second terminal arranged in parallel with each other, one end side of each being inserted into the housing and the other end side of each being projected from the housing,

the first terminal and the second terminal include: a base protruding from the housing; and a connecting portion formed wider than the base portion toward both sides in an arrangement direction of the first terminal and the second terminal and having a bolt insertion portion,

the connecting portion of the first terminal protrudes farther from the housing than the connecting portion of the second terminal in a terminal forming direction along the first terminal and the second terminal,

the base portion includes a plate-shaped flat plate portion having a thickness in an orthogonal direction orthogonal to both an arrangement direction of the first terminals and the second terminals and a terminal forming direction along the first terminals and the second terminals,

the base portion of the first terminal has a shape in which a side portion of the base portion adjacent to the connecting portion of the second terminal in the array direction is bent with respect to the flat plate portion.

Effects of the invention

In the connector of the above aspect, the connection portion of the first terminal protrudes farther from the housing than the connection portion of the second terminal in the terminal forming direction. That is, the connection portion of the first terminal and the connection portion of the second terminal are formed at positions shifted from each other in the terminal forming direction. Therefore, the pair of connection portions can be prevented from being excessively close to each other due to the arrangement of the pair of connection portions in the arrangement direction. This makes it easy to ensure electrical insulation between the first terminal and the second terminal.

Here, when the connection portion of the first terminal and the connection portion of the second terminal are formed at positions shifted from each other in the terminal forming direction and the distance between the outer sides of the first terminal and the second terminal in the arrangement direction (i.e., the length in the arrangement direction from the end portion of the first terminal on the side opposite to the second terminal to the end portion of the second terminal on the side opposite to the first terminal) is intended to be narrowed, the connection portion of the second terminal and the base portion of the first terminal are likely to approach each other in the arrangement direction, and the electrical insulation between the first terminal and the second terminal is likely to be lowered.

Therefore, the base portion of the first terminal has a shape in which a side portion of the base portion adjacent to the connecting portion of the second terminal in the arrangement direction is bent with respect to the flat plate portion. This makes it possible to secure a space between the connection portion of the second terminal and the base portion of the first terminal in the arrangement direction without increasing the outer space between the first terminal and the second terminal. This can ensure insulation between the first terminal and the second terminal while suppressing an increase in size. The base portion of the first terminal can be formed by bending without reducing the area of the cross section orthogonal to the terminal forming direction. This can suppress an increase in the resistance value of the entire first terminal.

As described above, according to the above aspect, the following connector can be provided: the electrical insulation between the pair of terminals can be ensured while suppressing an increase in size and resistance of the terminals.

Detailed Description

(embodiment mode 1)

An embodiment of the connector will be described with reference to fig. 1 to 8.

As shown in fig. 1, 2, and 5, the connector 1 of the present embodiment includes a housing 2, and a first terminal 31 and a second terminal 32.

The first terminals 31 and the second terminals 32 are arranged in parallel with each other. One end of each of the first terminal 31 and the second terminal 32 is inserted into the housing 2, and the other end thereof protrudes from the housing 2.

The first terminal 31 and the second terminal 32 include: a base 33 protruding from the housing 2; and a connection portion 34 formed wider than the base portion 33 on both sides in the arrangement direction (hereinafter referred to as "Y direction") of the first terminals 31 and the second terminals 32, and having a bolt insertion portion 341.

The connection portions 34 of the first terminals 31 protrude further from the housing 2 than the connection portions 34 of the second terminals 32 in a terminal forming direction (hereinafter referred to as "X direction") along the first terminals 31 and the second terminals 32.

The base portion 33 includes a flat plate portion 330, and the flat plate portion 330 is formed in a plate shape having a thickness in a perpendicular direction (hereinafter referred to as "Z direction") perpendicular to both the Y direction and the X direction. The base portion 33 of the first terminal 31 has a shape in which a side portion (a bent portion 36 described later) adjacent to the connection portion 34 of the second terminal 32 in the Y direction is bent with respect to the flat plate portion 330.

The present embodiment will be described in detail later.

In the present embodiment, unless otherwise specified, the first terminal 31 and the second terminal 32 may be collectively referred to as the terminal 3. The side of the housing 2 from which the first and second terminals 31 and 32 protrude in the X direction is referred to as the X1 side, and the opposite side is referred to as the X2 side. The radial direction of the connector 1 with the center axis of the connector 1 extending in the X direction as the center is simply referred to as the radial direction. The side of the connector 1 on the center axis in the radial direction is referred to as an inner peripheral side, and the side opposite thereto is referred to as an outer peripheral side.

[ connector 1 ]

As shown in fig. 6, the connector 1 is directly attached to a housing 13 mounted on an electric device such as an electric vehicle, and can relay electrical connection between an external power supply and components disposed in the housing 13.

[ casing 2 ]

The case 2 is made of resin having electrical insulation. As shown in fig. 1 to 3, the housing 2 includes a mounting portion 21, a terminal insertion portion 22, and a flange portion 23.

As shown in fig. 1 to 3, 5, and 6, the mounting portion 21 is formed in a cylindrical shape parallel to the X direction. The mounting portion 21 is formed in an area on the X2 side of the housing 2. As shown in fig. 5, the X2-side end of the first terminal 31 and the X2-side end of the second terminal 32 are exposed inside the mounting portion 21. In other words, the mounting portion 21 covers the X2-side end of the first terminal 31 and the X2-side end of the second terminal 32 from the outer peripheral side. A first partition wall 211 is formed inside the mounting portion 21, and the first partition wall 211 partitions between the X2-side end portion of the first terminal 31 and the X2-side end portion of the second terminal 32.

The inner space of the mounting portion 21 is opened on the X2 side, and a mating connector, not shown, is fitted from the X2 side to the inside of the mounting portion 21. In a state where the mating connector is fitted to the connector 1, the X2-side ends of the first and second terminals 31 and 32 exposed in the mounting portion 21 are electrically connected to the terminals of the mating connector. The terminal insertion portion 22 is formed so as to protrude toward the X2 side of the mounting portion 21.

As shown in fig. 5, the terminal insertion portion 22 has two cavities 221. The cavity 221 is a hole formed to penetrate the terminal insertion portion 22 in the X direction. The X2-side end of the cavity 221 communicates with the inner space of the mounting portion 21. The two cavities 221 are formed in such a manner as to be aligned in the Y direction.

The cavity 221 is opened on the X1 side, and the terminal 3 is inserted from the X1 side. That is, the first terminal 31 is inserted into one of the two cavities 221, and the second terminal 32 is inserted into the other.

As shown in fig. 6, a lance 222 for preventing the terminal 3 from coming off is formed in a wall portion of the housing 2 facing the cavity 221 in the Z direction. The lance 222 is configured to: is formed long in the X direction in a cantilever state so as to protrude toward the X2 side, and is capable of elastically flexing in the Z direction.

When the terminal 3 is inserted into the cavity 221, the terminal 3 is inserted while the lance 222 is bent in the Z direction by the terminal 3. Then, when the terminal 3 is inserted to a predetermined position within the cavity 221, the lance portion 222 is inserted into a through-hole formed in the terminal 3 by an elastic restoring force. Thereby, the lance portion 222 prevents the terminal 3 inserted to a predetermined position of the cavity 221 from being detached from the cavity 221.

As shown in fig. 5, a second partition wall 223 that partitions the two chambers 221 is formed between the two chambers 221 aligned in the Y direction. The second partition wall 223 is formed so as to be connected to the first partition wall 211 in the X direction. As shown in fig. 1 to 3, 5, and 6, a flange 23 is formed at a boundary between the mounting portion 21 and the terminal insertion portion 22 in the X direction.

The flange portion 23 is formed to protrude outward from the mounting portion 21 and the terminal insertion portion 22. As shown in fig. 1 and 4, metal bushings 12 are embedded in four corners of the flange portion 23, and the bushings 12 are used to insert bolts (see reference numeral 11 in fig. 6).

As shown in fig. 6, the housing 13 is formed with an arrangement hole 131, and the arrangement hole 131 is one turn larger than the terminal insertion portion 22 of the connector 1 and one turn smaller than the flange portion 23. When the connector 1 is attached to the housing 13, the terminal insertion portion 22 of the connector 1 is inserted into the arrangement hole 131 of the housing 13, and the surface of the flange portion 23 on the X1 side faces the housing 13 in the X direction. Then, bolt 11 is inserted through boss 12 from the X2 side of boss 12 and is screwed into a screw hole formed in case 13, whereby connector 1 is fixed to case 13.

As shown in fig. 5 and 6, an annular receiving groove 231 is formed on the surface of the flange portion 23 on the X1 side and on the inner peripheral side of the sleeve 12 at the four corners. The housing groove 231 is open toward the X1 side, and an annular seal member 14 made of rubber or the like is housed inside the housing groove. In a state where the connector 1 is fastened to the housing 13 by the bolt 11, the seal member 14 is compressed by the axial force of the bolt 11, and is in close contact with both the housing groove 231 and the housing 13. This ensures the sealing property between the connector 1 and the housing 13.

[ terminal 3 ]

The first terminal 31 and the second terminal 32 are terminals connected to a positive electrode and a negative electrode of a power supply, and the potential difference therebetween is a high potential difference of, for example, about 600V. As shown in fig. 5, the first terminals 31 are inserted into one side cavity 221, and the second terminals 32 are inserted into the other side cavity 221. The terminals 3 are formed in a plate shape having a thickness in the Z direction and a length in the X direction. The first terminals 31 are formed longer than the second terminals 32.

As shown in fig. 8, the first terminal 31 and the second terminal 32 are inserted into the cavity 221 from the X1 side with respect to the cavity 221 along the X direction, and the X1 side ends of these terminals protrude inward of the mounting portion 21 as shown in fig. 5. In the X direction, the position of the X2-side end of the first terminal 31 and the position of the X2-side end of the second terminal 32 are aligned.

As shown in fig. 6 and 8, the first terminal 31 and the second terminal 32 are formed with positioning portions 35 protruding from the periphery on both sides in the Y direction and bent toward one side in the Z direction at portions disposed in the cavities 221. The positioning portion 35 is a portion for positioning the terminal 3 with respect to the cavity 221.

As shown in fig. 5, the X1-side portions of the first and second terminals 31 and 32 protrude from the cavity 221 toward the X1 side. The amount of protrusion of the first terminals 31 from the cavities 221 in the X direction is greater than the amount of protrusion of the second terminals 32 from the cavities 221 in the X direction. Therefore, the position of the X1 side end of the first terminal 31 is located closer to the X1 side than the position of the X1 side end of the second terminal 32.

The first terminal 31 and the second terminal 32 have a base portion 33 and a connecting portion 34 in this order from the X2 side at the portions projecting from the cavity 221. The base 33 includes: a flat plate portion 330 formed in a substantially rectangular plate shape that is long in the X direction and has a thickness in the Z direction; and a bent portion 36 bent in the Z direction from the flat plate portion 330.

As shown in fig. 1 and 2, the bent portion 36 of the first terminal 31 is bent from the end edge of the flat plate portion 330 of the first terminal 31 on the side of the second terminal 32 in the Y direction toward one side in the Z direction. The bent portion 36 of the second terminal 32 is bent from the end edge of the flat plate portion 330 of the second terminal 32 on the first terminal 31 side in the Y direction toward one side in the Z direction. The bent portions 36 of the first terminals 31 and the bent portions 36 of the second terminals 32 are bent toward the same side so as to protrude toward the same side in the Z direction. The periphery of the boundary portion with the bent portion 36 in the flat plate portion 330 of the base portion 33 protrudes in the Y direction from the periphery, and the bent portion 36 is formed in the Z direction from the protruding portion.

The first terminal 31 is bent only at the portion of the base portion 33 on the side of the second terminal 32 in the Y direction, and the second terminal 32 is bent only at the portion of the base portion 33 on the side of the first terminal 31 in the Y direction. As a result, as shown in fig. 7, the region of the base 33 in the X direction where the bent portion 36 is formed has an L-shaped cross section orthogonal to the X direction. At least a portion of the first terminal 31 adjacent to the connection portion 34 of the second terminal 32 in the Y direction is formed in an L-shape in cross section orthogonal to the X direction.

As shown in fig. 1 and 2, the bent portion 36 is formed substantially entirely in the X direction of the base portion 33. The base portion 33 of the first terminal 31 is longer than the base portion 33 of the second terminal 32 in the X direction, and accordingly, the bent portion 36 formed in the first terminal 31 is longer than the bent portion 36 formed in the second terminal 32 in the X direction. At least a part of the bent portion 36 formed in the first terminal 31 is formed at a position facing the position of the connection portion 34 of the second terminal 32 which is most protruded toward the first terminal 31 in the Y direction.

As shown in fig. 6, the bent portion 36 is disposed on the X1 side of the cavity 221. In the X direction, a gap G is formed between the bent portion 36 and the case 2. That is, the bent portion 36 is disposed at a position slightly away from the case 2 toward the X1 side.

In the Y direction, the bent portion 36 is formed so as not to protrude from the connecting portion 34. That is, the bent portion 36 is formed so as to be accommodated inside the formation region of the connection portion 34 in the Y direction.

The connecting portion 34 extends from the X1 side end of the flat plate portion 330 toward the X1 side. The connecting portion 34 is formed at the X1-side end of the terminal 3. As shown in fig. 1 to 3 and 5, the connecting portion 34 is formed to be wider than the base portion 33 so as to protrude from the base portion 33 on both sides in the Y direction. The connecting portion 34 is circular when viewed from the Z direction, and has a bolt insertion portion 341 formed to penetrate in the Z direction at a central portion thereof. The terminal 3 is connected to another conductive member by a bolt, not shown, inserted into the bolt insertion portion 341.

The connection portions 34 of the first terminals 31 and the connection portions 34 of the second terminals 32 are formed at positions shifted from each other in the X direction. The connection portion 34 of the first terminal 31 is formed on the X1 side of the connection portion 34 of the second terminal 32. Thus, the connection portions 34 of the first terminals 31 and the connection portions 34 of the second terminals 32 are formed so as to be aligned in an oblique direction that is oblique to both the X direction and the Y direction. As shown in fig. 2, the virtual straight line L1 that connects the connection portion 34 of the first terminal 31 and the connection portion 34 of the second terminal 32 at the shortest distance is preferably inclined so that the angle θ with respect to the virtual straight line L2 parallel to the Y direction is less than 45 ° (i.e., 45 (pi/180) rad). In this case, the connection portions 34 of the first terminals 31 and the connection portions 34 of the second terminals 32 can be arranged relatively close to each other, and the connector 1 can be easily prevented from being enlarged.

The connection portion 34 of the second terminal 32 is formed to be aligned in the Y direction with the base portion 33 of the first terminal 31. In the X direction, the position of the X1-side end of the second terminal 32 and the position of the X2-side end of the first terminal 31 are located at the same position.

[ Shield case 5 ]

As shown in fig. 4 to 6, the shield case 5 is disposed on the inner peripheral side of the sealing member 14 in the housing 2, and the shield case 5 surrounds the first terminal 31 and the second terminal 32 from the entire periphery. The shield case 5 includes a cylindrical case main body 51 and a plurality of elastic contact pieces 52 formed to extend from the case main body 51 to the outer peripheral side.

As shown in fig. 5 and 6, the case main body 51 is inserted into the housing 2 along the X direction. The housing main body 51 is formed so as to surround at least the portions of the first terminals 31 and the second terminals 32 protruding inside the mounting portion 21 of the housing 2.

As shown in fig. 6, a part of the case main body 51 has a retaining piece 511 bent inward. The anti-slip-off piece 511 faces the step portion 212 formed on the inner peripheral portion of the mounting portion 21 of the housing 2 in the X direction, and prevents the shield case 5 inserted to a predetermined position of the housing 2 from slipping off from the housing 2 to the X1 side.

The elastic contact piece 52 is formed so as to be folded back from the X1-side end of the case main body portion 51 toward the X2 side. The elastic contact piece 52 is formed in a cantilever state at the X1-side end of the case main body 51, and is configured to be able to flex in the radial direction. The elastic contact piece 52 is formed in an arc shape bulging outward in the circumferential direction, and a contact portion 521 struck outward in the circumferential direction is formed at the top thereof. The elastic contact piece 52 is elastically pressed against the inner surface of the arrangement hole 131 of the housing 13 in a state where the connector 1 is fastened to the housing 13. The case 13 is a conductor, and is fitted to the case 13 through the connector 1 so that the shield case 5 is grounded in the case 13.

As described above, a high voltage of about 600V is applied between the first terminal 31 and the second terminal 32, and a relatively large current flows. Therefore, noise may be radiated from the first terminal 31 and the second terminal 32 to the surroundings. Therefore, the surroundings of the first terminal 31 and the second terminal 32 are surrounded by the shield case 5, thereby preventing noise radiated from the terminal 3 from leaking to the outside.

[ effect ] of action

Next, the operation and effects of the present embodiment will be described.

In the connector 1 of the present embodiment, the connection portions 34 of the first terminals 31 protrude further away from the housing 2 than the connection portions 34 of the second terminals 32 in the X direction. That is, the connection portions 34 of the first terminals 31 and the connection portions 34 of the second terminals 32 are formed at positions shifted from each other in the X direction. Therefore, the pair of connection portions 34 can be prevented from being excessively close to each other due to the pair of connection portions 34 being arranged in the Y direction. This makes it easy to ensure electrical insulation between the first terminal 31 and the second terminal 32.

Here, when the connection portion 34 of the first terminal 31 and the connection portion 34 of the second terminal 32 are formed at positions shifted from each other in the X direction and the outer side interval of the first terminal 31 and the second terminal 32 in the Y direction is intended to be narrowed, the connection portion 34 of the second terminal 32 and the base portion 33 of the first terminal 31 approach each other in the Y direction, and there is a possibility that the electrical insulation between the first terminal 31 and the second terminal 32 is lowered.

Therefore, the base portion 33 of the first terminal 31 has a shape in which the side portion adjacent to the connecting portion 34 of the second terminal 32 in the Y direction is bent with respect to the flat plate portion 330. This can secure the distance between the connection portion 34 of the second terminal 32 and the base portion 33 of the first terminal 31 in the Y direction without increasing the outer distance between the first terminal 31 and the second terminal 32. This can prevent the size from increasing, and can ensure insulation between the first terminal 31 and the second terminal 32. The base 33 can be formed to be bent without reducing the area of the cross section orthogonal to the X direction. This can suppress an increase in the resistance value of the entire first terminal 31.

In addition, a portion of the base portion 33 of the first terminal 31 adjacent to the connection portion 34 of the second terminal 32 in the Y direction is formed in an L-shape in cross section orthogonal to the X direction. That is, the first terminal 31 is bent only at the portion of the base portion 33 on the second terminal 32 side in the Y direction. Therefore, the productivity of the first terminal 31 can be improved as compared with the case where both sides of the first terminal 31 in the Y direction are bent.

The base portion 33 of the second terminal 32 has a shape in which a side portion (bent portion 36) adjacent to the first terminal 31 in the Y direction is bent with respect to the flat plate portion 330. That is, in the present embodiment, each of the first terminals 31 and the second terminals 32 has a bent shape. Therefore, the first terminals 31 and the second terminals 32 can be further prevented from coming close to each other in the Y direction, and electrical insulation between the first terminals 31 and the second terminals 32 can be ensured.

As described above, according to the present embodiment, the following connector can be provided: the electrical insulation between the pair of terminals can be ensured while suppressing an increase in size and resistance of the terminals.

(embodiment mode 2)

As shown in fig. 9, the present embodiment is an embodiment in which the shape of the base 33 is changed from that of embodiment 1.

In the present embodiment, the flat plate portion 330 of the base portion 33 of the first terminal 31 includes the projecting portion 331 at the end portion on the side opposite to the second terminal 32 in the Y direction and at the portions adjacent to both sides of the bent portion 36 in the X direction, and the projecting portion 331 projects toward the side opposite to the second terminal 32 in the Y direction. Similarly, the flat plate portion 330 of the base portion 33 of the second terminal 32 includes a protruding portion 331 at an end portion on the opposite side to the first terminal 31 side in the Y direction and at a portion adjacent to both sides of the bent portion 36 in the X direction, and the protruding portion 331 protrudes toward the opposite side to the first terminal 31 side in the Y direction. Thus, the other side of the flat plate portion 330 of the base portion 33 in the Y direction, which is opposite to the side where the bent portion 36 is formed, has a shape recessed in the Y direction.

The rest is the same as embodiment 1.

Note that, of the reference numerals used in embodiment 2 and thereafter, the same reference numerals as those used in the present embodiment denote the same components and the like as those in the present embodiment unless otherwise specified.

The connector 1 of the present embodiment has the projecting portion 331. Thus, the following can be prevented: in the region of the base 33 in the X direction other than the region where the bent portion 36 is formed, the cross-sectional area orthogonal to the X direction is reduced. This can suppress the following: in a part of the X direction, the cross section of the terminal 3 orthogonal to the X direction is reduced and the resistivity is increased.

The other components have the same operational effects as those of embodiment 1.

The present invention is not limited to the embodiments described above, and can be applied to various embodiments without departing from the scope of the invention. For example, the portion of the terminal protruding from the housing is formed so as to be linear in one direction, but may be formed in a curved shape. In this case, the terminal forming direction means a direction along the bending of the terminal.

The shape of the connecting portion is circular, but is not limited to this, and other shapes such as a square shape and a U shape may be adopted.

The bent portions of the first terminal and the bent portions of the second terminal are bent toward the same side, but may be bent toward the opposite side.
