Description

Charging inlet

The technology disclosed by the present specification relates to a charging inlet.

JP, 2015-158982, A

In the above configuration, it is necessary to match the inner diameter and the outer diameter of the guide portion with the outer diameter of the wire connection portion inserted inside and the outer diameter of the flange portion with which the guide portion abuts. For this reason, if there is a design change in the thickness of the wire connected to the charging inlet, the design change of the retainer needs to be performed if the design of the wiring connection is changed according to the thickness of the wire. .

In order to eliminate the need for design change of the retainer, it is conceivable to adopt a configuration in which the retainer is engaged from the direction perpendicular to the axial direction of the terminal (the direction perpendicular to the insertion and removal direction of the terminal with respect to the housing). According to such a configuration, the configuration of the engaging portion between the terminal and the retainer can be made common regardless of the thickness of the electric wire to be connected. However, in such a configuration, in the terminals, the portion on the rear side (the wire side) of the portion engaged with the retainer is exposed to the outside of the retainer, which may cause a short circuit between adjacent terminals. Ru.

The charging inlet disclosed by the present specification includes a plurality of terminals including a terminal connection portion and a wire connection portion connected from the terminal connection portion and connected to an electric wire, and a terminal insertion portion capable of inserting the terminal connection portion.

According to the above configuration, the retainer is assembled from the direction perpendicular to the axial direction of the terminal connection portion (that is, the direction perpendicular to the insertion and removal direction of the terminal with respect to the housing). Then, the peripheral edge portion of the slit portion in the retaining wall is locked to the retainer receiving wall, so that the terminal can be prevented from being detached from the housing. According to such a configuration, by sharing the configurations of the slit fitting portion and the retainer receiving wall among a plurality of types of terminals having different designs of the wire connection portion, the thickness of the wire connected to the charging inlet is increased. Even if there is a design change, the design change of the retainer becomes unnecessary.

However, in such a configuration, in the terminal, the portion on the rear side (wire side) of the portion engaged by the retainer is exposed to the outside from the space surrounded by the terminal accommodating portion and the retaining wall. . Therefore, the retainer is provided with an insulating wall extending from the retaining wall to separate the portions of the adjacent terminals exposed to the outside. Thereby, a short circuit between adjacent terminals can be suppressed.

In the above configuration, the housing includes an opposing wall facing the retaining wall, and one of the housing and the retainer protrudes from one of the retaining wall and the opposing wall toward the other And a guide rib extending in a direction perpendicular to the axial direction of the terminal connection portion, and the other of the housing and the retainer has a guide groove for receiving the guide rib, and the guide rib and the guide groove are adjacent to each other. It may be disposed between the plurality of matching terminals.

According to such a configuration, since the assembly of the retainer to the housing is guided by the guide ribs being fitted into the guide grooves, the assembly of the retainer to the housing can be smoothly performed. Moreover, the distance (creeping distance) of the path | route which extends along the wall surface of an opposing wall from one terminal of several adjacent terminals to the other terminal can be enlarged, and the short circuit between adjacent terminals can be suppressed.

According to the charging inlet disclosed by the present specification, even when there is a design change in the thickness of the electric wire connected to the charging inlet, the design change of the retainer becomes unnecessary and a short circuit between adjacent terminals Can be suppressed.
