Background

Conventionally, as a wire-side connector to be connected to a terminal plate, a wire-side connector described in japanese patent application laid-open No. 2006 and 31962 (patent document 1) is known. The wire-side connector includes a 1 st connector directly attached to a device, and the 1 st connector includes a 1 st housing, a plurality of 1 st terminal parts, and the like. The rear end of the 1 st terminal fitting protrudes rearward from the rear end surface of the 1 st housing and is exposed to the outside of the 1 st housing. In addition, a partition wall for partitioning the adjacent pair of 1 st terminal fittings is provided on the rear end surface of the 1 st housing.

Disclosure of Invention

Problems to be solved by the invention

However, if the wire-side connector is accidentally dropped, the 1 st terminal fitting may strike the ground and be damaged. Specifically, with respect to the pair of 1 st terminal fittings located on both sides among the plurality of 1 st terminal fittings, although there is a partition wall on the adjacent 1 st terminal fitting side, there is no partition wall provided on the opposite side, and therefore, when the wire-side connector is dropped downward with the side where no partition wall is provided, there is a possibility that the 1 st terminal fitting hits the ground.

Means for solving the problems

The connector disclosed in the present specification includes: a housing having a main body portion through which a horizontally long work hole is provided; and a plurality of terminals held by the housing, the plurality of terminals being arranged in a lateral direction in the work hole, wherein each of the terminals includes: an embedded portion embedded in the housing; an internal connection portion connected to the embedded portion and disposed inside the working hole; and an external connection portion connected to the internal connection portion and disposed outside the work hole, wherein the housing includes a pair of protection walls provided to protrude from the main body portion and disposed on both lateral sides of a terminal group including the plurality of terminals, and a tip portion of the protection wall is disposed at a position farther from the main body portion than the external connection portion in a penetrating direction of the work hole.

According to this configuration, when the connector is erroneously dropped, the protective wall hits the ground before the external connection portion, and therefore, the external connection portion can be prevented from being damaged. Further, since the pair of protection walls is disposed on both lateral sides of the plurality of external connection portions, the pair of external connection portions located on both lateral sides can be protected by the pair of protection walls.

The connector disclosed in the present specification may be configured as follows.

The outer connecting portion is composed of a vertical portion and a horizontal portion, the vertical portion is connected to the inner connecting portion, the horizontal portion is connected to the vertical portion, and the protective wall includes: a 1 st protective wall disposed on one side of the longitudinal direction orthogonal to the lateral direction; and a 2 nd protective wall disposed on the other side in the longitudinal direction.

According to this configuration, one side of the horizontal portion can be protected by the 1 st protective wall, and the other side of the horizontal portion can be protected by the 2 nd protective wall.

The protection wall may be configured to protrude from a hole edge portion of the work hole of the body portion in a direction in which the work hole penetrates.

According to this configuration, since the protection wall is provided at the hole edge portion of the working hole, the connector can be prevented from being enlarged.

Effects of the invention

According to the connector disclosed in the present specification, the terminal can be protected in the case where the connector is accidentally dropped.

Detailed Description

< embodiment >

The embodiment will be described with reference to fig. 1 to 4. As shown in fig. 1 and 2, the connector 10 of the present embodiment includes: a housing 20 made of synthetic resin; a plurality of terminals 30 held by the housing 20; and a plate 40 for mounting the housing 20 to a device such as a motor. As shown in fig. 1, the housing 20 includes: a main body 21 in which a metal plate 40 is integrally held by the main body 21; and a pair of left and right protective walls 22 provided to protrude downward from the lower surface of the main body 21. As shown in fig. 2, a laterally long work hole 23 is provided through the body 21.

As shown in fig. 2, a plurality of terminals 30 are arranged in the horizontal direction in the working hole 23 so as to face downward and upward. As shown in fig. 4, the terminal 30 is formed into a substantially crank shape by press working a conductive metal plate, and the terminal 30 includes: an embedded portion 31 embedded in the inside of the case 20; an internal connection portion 32 connected to the embedded portion 31 and disposed inside the working hole 23; and an external connection portion 33 connected to the internal connection portion 32 and disposed outside the working hole 23 (a space below the working hole 23). As shown in fig. 4, the outer connecting portion 33 includes a vertical portion 34 and a horizontal portion 35, the vertical portion 34 is connected to the inner connecting portion 32 and extends in the vertical direction, the horizontal portion 35 is connected to the vertical portion 34 and extends in the horizontal direction, and a bolt hole 36 is formed in the horizontal portion 35 so as to penetrate in the vertical direction. As shown in fig. 2, the horizontal portion 35 extends in the longitudinal direction perpendicular to the lateral direction.

The plate 40 is held in a state of protruding laterally from the outer peripheral side surface of the body portion 21. As shown in fig. 2, the plate 40 is formed in a laterally long shape, and is formed in a substantially rectangular shape as a whole, similarly to the work hole 23. A plurality of holes 41 are formed through the plate 40 on both left and right sides of the body 21. As shown in fig. 4, the plate 40 is disposed on the lower end side of the body 21.

Then, the protective wall 22 provided on the main body 21 of the case 20 is configured to include: a 1 st protective wall 24 disposed on one side in the longitudinal direction (the right side in the figure of fig. 4); and a 2 nd protective wall 25 disposed on the other side in the longitudinal direction (left side in the figure of fig. 4). Both the 1 st protective wall 24 and the 2 nd protective wall 25 are formed to protrude downward from the hole edge portion 23A of the work hole 23. As shown in fig. 2, the 1 st protective wall 24 is disposed on the side of the horizontal portion 35 located on the left and right sides on the base end side, and the 2 nd protective wall 25 is disposed on the side of the horizontal portion 35 located on the left and right sides on the front end side.

That is, the protection wall 22 is composed of a pair of left and right first protection walls 24 and a pair of left and right second protection walls 25, and the plurality of horizontal portions 35 are located inside the region surrounded by the protection walls 24 and 25. More specifically, in fig. 2, all the horizontal portions 35 are located inside the region surrounded by the wiring L1, the wiring L2, the wiring L3, and the wiring L4, the wiring L1 is circumscribed with the pair of left and right 1 st protective walls 24, the wiring L2 is circumscribed with the pair of left and right 2 nd protective walls 25, the wiring L3 is circumscribed with the left 1 st protective wall 24 and the left 2 nd protective wall 25, and the wiring L4 is circumscribed with the right 1 st protective wall 24 and the right 2 nd protective wall 25.

As shown in fig. 4, the horizontal portion 35 is disposed at a position farther from the main body 21 than the external connection portion 33 in the penetrating direction of the working hole 23, in other words, the horizontal portion 35 is located above the lower end 24L of the 1 st protective wall 24 and above the lower end 25L of the 2 nd protective wall 25. Specifically, all the horizontal portions 35 are located in the upper region of the connection line L5, and the connection line L5 circumscribes the lower end 24L of the 1 st protective wall 24 and the lower end 25L of the 2 nd protective wall 25. Therefore, when the connector 10 is erroneously dropped, the lower end 24L of the 1 st protective wall 24 or the lower end 25L of the 2 nd protective wall 25 hits the ground first, and the horizontal portion 35 does not contact the ground even if the lower ends 24L, 25L of all the protective walls 24, 25 contact the ground.

In the present embodiment described above, when connector 10 is erroneously dropped, protective wall 22 strikes the ground before external connection portion 33, and therefore, external connection portion 33 can be prevented from being damaged. Further, since the pair of protection walls 22 is disposed on both lateral sides of the plurality of external connection portions 33, the pair of external connection portions 33 located on both lateral sides can be protected by the pair of protection walls 22.

The outer connection portion 33 is constituted by a vertical portion 34 connected to the inner connection portion 32 and a horizontal portion 35 connected to the vertical portion 34, and the protective wall 22 may be constituted by a 1 st protective wall 24 and a 2 nd protective wall 25, the 1 st protective wall 24 being disposed on one side in the longitudinal direction orthogonal to the lateral direction, and the 2 nd protective wall 25 being disposed on the other side in the longitudinal direction.

In this way, one side of the horizontal portion 35 can be protected by the 1 st protective wall 24, and the other side of the horizontal portion 35 can be protected by the 2 nd protective wall 25.

The protection wall 22 may be configured to protrude from the hole edge portion 23A of the work hole 23 of the body 21 in the penetrating direction of the work hole 23.

With this configuration, the protection wall 22 is provided at the hole edge portion 23A of the working hole 23, so that the connector 10 can be prevented from being enlarged.
