The present invention prevents two connector housings of a connector from being in a half-fitted condition by increasing restoring force which separates the two housing. A connector includes: a first connector housing including a lock projection; a second connector housing to be fitted to the first connector housing and integrally including a lock arm which is elastically deformed by the lock projection and is engaged with the lock projection; a lock ensuring member including a body which is attached to the second connector housing and movable between an allowing position and a preventing position, and an interference arm which is integrally provided on the body and includes a pressing projection. The pressing projection presses the lock arm while the lock projection deforms the lock arm at the allowing position, and the interference arm abuts the lock arm so as to prohibit the lock arm from deforming in the preventing position.
1. A connector comprising:
a first connector housing including a lock projection;
a second connector housing to be fitted to the first connector housing and integrally including a lock arm which is elastically deformed by the lock projection and is engaged with the lock projection;
a lock ensuring member including a body which is attached to the second connector housing and movable between an allowing position and a preventing position, and an interference arm which is integrally provided on the body and includes a pressing projection,
wherein the pressing projection presses the lock arm while the lock projection deforms the lock arm at the allowing position, and the interference arm abuts the lock arm so as to prohibit the lock arm from deforming in the preventing position.
2. The connector according to claim 1 , wherein the interference arm has a free end, the pressing projection is provided on the free end, and the pressing projection presses an end of the lock arm.
3. The connector according to claim 2 , wherein the pressing projection superposes the end of the lock arm in a direction in which the lock arm deforms at the allowing position.
4. The connector according to claim 1 , wherein the body is prohibited from moving until the lock arm is engaged with the lock projection and the body is movable while the lock projection is engaged with the lock projection.
5. The connector according to claim 3 , wherein the interference arm includes a interference projection which interferes with the lock arm in a direction in which the body is movable until the lock projection is engaged with the lock arm so as to prevent the body from moving and not interferes the lock arm after the lock projection is engaged with the lock arm so as to make the body movable.
