Abstract

A connector includes a housing including a cavity extending in a first direction, a terminal and a retainer. The housing is formed with a locking lance resiliently deformable in a second direction orthogonal to the first direction. The retainer includes two lock pieces, a restricting portion and a rib extending from the restricting portion. The restricting portion is disposed at a position deviated in the second direction from the center plane CP. The locking lance interferes with the terminal and is resiliently deformed toward the center plane CP in the second direction in the process of inserting the terminal into the cavity. The two lock pieces interfere with the housing and are resiliently deformed away from the center plane CP in the second direction in the process of moving the retainer from a temporary locking position to a complete locking position.

First claim

What is claimed is:

1 . A connector, comprising:
a housing including a cavity extending in a first direction; a terminal to be disposed in the cavity; and a retainer to be assembled with the housing movably in the first direction between a temporary locking position and a complete locking position, the housing being formed with a locking lance disposed in the cavity and resiliently deformable in a second direction orthogonal to the first direction, the retainer including two lock pieces to be locked to the housing, a restricting portion for allowing insertion of the terminal into the cavity when the retainer is at the temporary locking position and interfering with the locking lance to retain the terminal in the cavity when the retainer is at the complete locking position and a rib extending from the restricting portion, a plane disposed in a center between the two lock pieces in the second direction being a center plane, the restricting portion being disposed at a position deviated in the second direction from the center plane, the locking lance interfering with the terminal and being resiliently deformed toward the center plane in the second direction in the process of inserting the terminal into the cavity, the two lock pieces interfering with the housing and being resiliently deformed away from the center plane in the second direction in the process of moving the retainer from the temporary locking position to the complete locking position, and the rib suppressing the restricting portion from being displaced away from the center plane in the second direction by contacting the housing in the process of moving the retainer from the temporary locking position to the complete locking position.

2 . The connector of claim 1 , wherein:
the restricting portions include a first restricting portion and a second restricting portion disposed on a side opposite to the first restricting portion with respect to the center plane, the ribs include a first rib extending from the first restricting portion and a second rib extending from the second restricting portion, the cavities include a first cavity corresponding to the first restricting portion and a second cavity corresponding to the second restricting portion, and the locking lances include a first locking lance disposed in the first cavity and a second locking lance disposed in the second cavity.

3 . The connector of claim 1 , wherein the rib is disposed at a position overlapping the locking lance when viewed from the first direction.

4 . The connector of claim 1 , wherein:
the housing includes a recess open toward one side in the first direction and configured to receive the rib, the rib includes a guide portion disposed on an end part on the other side in the first direction, and the guide portion is inclined to approach the center plane in the second direction toward the other side in the first direction.

5 . The connector of claim 1 , wherein:
the housing includes a recess open toward one side in the first direction and configured to receive the rib, the terminal is inserted into the cavity from the other side in the first direction, the rib includes a first surface constituting the cavity together with the housing and an inclined portion continuous with the first surface and disposed on an end part of the rib on the other side in the first direction, the first surface is facing the terminal from one side in a third direction orthogonal to both the first and second directions, and the inclined portion is inclined to be located more on the one side in the third direction toward the other side in the first direction.
