Definitions
- the present invention relates to a connector assembly for connecting terminals.
- Vehicles such as an electric vehicle that travels using an electric motor or a hybrid vehicle that travels using an engine and an electric motor travel by being supplied with electric power from an installed power supply device.
- an electric motor and an inverter are connected by an electric wire such as a motor cable, and the inverter is connected to an electric connection box (junction box) provided in the power supply device. Power is being supplied. At that time, the inverter and the electrical junction box are connected to each other via a predetermined connector member (connector assembly).
- a mounting hole is formed in a case such as an inverter or an electric junction box, and a device side terminal is provided inside the case, and a wire side terminal connected to a plurality of wires is a housing. And the housing is fitted in the mounting hole so that each electric wire side terminal is connected to the device side terminal (see Patent Document 1).

- the sealing member attached to the housing is not circular but elliptical. Therefore, when the seal member is displaced in the circumferential direction with respect to the housing, there is a possibility that a part of the seal member is lifted from the groove portion of the housing or excessively stretched.
- the seal member is mounted in such a state, when the housing is fitted into the mounting hole, the close contact state of the seal member with respect to the groove portion of the housing and the inner peripheral portion of the mounting hole is uniform in the circumferential direction. Therefore, the sealing performance (sealing performance) is deteriorated.
- Patent Document 1 includes a locking portion (convex portion) provided in the seal member and a restriction portion (recessed portion) formed in the housing.
- a seal member is positioned in the circumferential direction with respect to the housing, and a configuration example of a connector assembly in which rotation of the seal member in the circumferential direction with respect to the housing is prevented is disclosed.

- the force in the front-rear direction acting on the seal member can be loaded, there is a possibility that the force acting in the circumferential direction cannot be sufficiently loaded. Therefore, when fitting the housing in the mounting hole, if the operator touches the seal member and a circumferential force is accidentally applied, the seal member rotates in the circumferential direction with respect to the housing depending on the degree. It is impossible to exclude the possibility of being lost. As a result, the seal member rides on the housing, and when the housing is fitted into the mounting hole, the seal member may be caught and damage such as cutting may occur.
- the present invention has been made based on this, and an object thereof is to reliably suppress the rotation of the seal member with respect to the circumferential direction of the housing and to improve the sealing performance in the connector assembly.

- the convex portion and the concave portion are A connector assembly formed in a shape that meshes with each other in a direction along the curved portion of the control member.
- the connector assembly having the configuration (1) even when a circumferential force is applied to the seal member, the force is reliably loaded by the engagement between the convex portion and the concave portion. Can do. Therefore, for example, even when the operator touches the seal member when fitting the connector assembly into the mounting hole of the connection counterpart device, a force in the circumferential direction is applied to the seal member. A situation in which the seal member rotates in the circumferential direction with respect to the housing can be effectively prevented.
- the convex portion has a convex meshing end formed so as to taper as it meshes with the concave portion, and the concave portion is meshed with the convex portion.
