ABSTRACT:
A coupling confirming mechanism for an electric connector having a first and second connector housings, capable of confirming the proper coupling of the first and second connector housings and double-locking the first and second connector housings. The coupling confirming mechanism comprises: a locking arm having a locking projection formed on the first connector housing; a locking lever pivotally joined at its rear end to the first connector housing and provided at its front end with an insulating projection, and at its front end with locking fingers; locking projections formed on the second connector housing; a break contact formed of a pair of short-circuiting terminals disposed in a short-circuiting terminal chamber formed in the second connector housing. The locking fingers of the locking lever is able to engage the locking projections of the second connector housing and the insulating projection of the same is able to break the break contact only when the first and second connector housings are properly coupled. The first and second connector housings can be double-locked by the engagement of the locking projection of the locking arm and the second connector housing and by the engagement of the locking lever and the second connector housing only when the first and second connector housings are properly coupled.
