ABSTRACT:
A perfect coupling confirming mechanism for an electric connector having a first connector housing and a second connector housing, employing two electrical contactors, among those accommodated in contactor chambers formed in the second connector housing, as check contactors for the confirmation of the perfect coupling of the first and second connector housings. The first connector housing is provided with a principal locking arm provided with a first and second locking projections. A locking slider and a short-circuiting member are provided movably in the second connector housing. When the first and second connector housings are coupled perfectly, the first locking projection and the second connector housing are engaged to lock the first and second connector housings to each other in a primary locked state. In this state, the locking slider is advanced so that the locking slider engages the second locking projection of the principal locking arm to lock the first and second connector housings in a secondary locked state and to disconnect the check contactors electrically by the short-circuiting member. Thus, the first and second connector housings are double-locked. When the first and second connector housings are coupled imperfectly, the locking slider is unable to engage the second locking projection of the principal locking arm and the check contactors remain connected electrically.
