Connector

Claim 1

A connector comprising: a pair of connector housings each including a front half portion for accommodating a terminal and which are coupled with each other; a locking mechanism including a cantilever-like resilient locking member having a leading end and disposed on one of said pair of connector housings, and a locking portion disposed on the other connector housing, in which the leading end of said cantilever-like resilient locking member of the one of said pair of connector housings interferes with said locking portion of the other connector housing so as to be flexed away from a normal state and is then restored to its normal state after a lapse of predetermined time so as to be brought into engagement with said locking portion; and a detecting spacer which is operative to be locked and connected to one of said pair of connector housings by means of another locking member, a lock-releasing portion being provided on the other connector housing for releasing locking between said detecting spacer and said one of said pair of connector housings when said other connector housing is properly coupled with said one of said pair of connector housings, and a second locking portion being provided on said detecting spacer so as to interfere with said cantilever-like resilient locking member of said locking mechanism when said cantilever-like resilient locking member is in a flexed posture which is away from its normal state, to thereby prevent the withdrawal of said detecting spacer when said locking mechanism for said pair of connector housings is in a lock-error condition.
