Abstract

An engagement member mounted to a first housing allows a movement of a fitting detection member from a complete engagement position to a temporary engagement position without interfering with the fitting detection member and prevents a movement of the fitting detection member in a second direction from the temporary engagement position by interfering with the fitting detection member.

First claim

What is claimed is:

1. A connector comprising:
a first housing configured to house a terminal;
a second housing configured to house a mating terminal and fittable with the first housing;
a fitting detection member mounted from a rear of the first housing in a first direction in which the first housing approaches the second housing in a fitted direction between the first housing and the second housing, the fitting detection member being configured to detect a fitted state between the first housing and the second housing; and
an engagement member mounted to the first housing and configured to engage the terminal housed in the first housing,
wherein the first housing comprises:
a fitting lock arm extending toward a second direction opposite to the first direction;
a first locking part provided in the fitting lock arm and engageable with the fitting detection member; and
a second locking part provided in the fitting lock arm and engageable with the second housing,

the fitting detection member comprises:
a detection lock arm extending toward the first direction;
a detection protrusion provided in the detection lock arm;
a deflection regulator configured to regulate a deflection amount of the fitting lock arm; and
a first locked part engageable with the first locking part,

the second housing comprises a second locked part engageable with the second locking part,
the fitting detection member is movable between a temporary engagement position and a complete engagement position, the temporary engagement position at which a contact between the detection protrusion and the second locking part prevents a movement of the fitting detection member in the first direction, the complete engagement position to which the fitting detection member moves from the temporary engagement position in the first direction and at which the first locked part is engaged with the first locking part,
the second locked part engaged with the second locking part releases the contact between the detection protrusion and the second locking part located at the temporary engagement position and allows the fitting detection member to move in the first direction,
the deflection regulator of the fitting detection member located at the complete engagement position regulates the deflection amount of the fitting lock arm within a range in which an engagement between the second locking part and the second locked part is unreleasable while an engagement between the first locking part and the first locked part is releasable, and
the engagement member mounted to the first housing allows a movement of the fitting detection member from the complete engagement position to the temporary engagement position without interfering with the fitting detection member and prevents a movement of the fitting detection member in the second direction from the temporary engagement position by interfering with the fitting detection member.

2. The connector of claim 1 , wherein
the engagement member mounted to the first housing has a protrusion protruding outwardly of the first housing, and
the protrusion of the engagement member mounted to the first housing prevents the movement of the fitting detection member in the second direction from the temporary engagement position by contacting the fitting detection member.
