Abstract Two mating connector housings are connected and locked together by a resilient lock arm formed on a first connector housing and an engagement portion formed on a second connector housing that cooperates with the resilient lock arm. The first connector housing is also provided with a lock verification slider that can be advanced toward the first connector housing only when the two connector housings are completely connected. A pair of engagement detection terminals are provided to either the first connector housing or the lock verification slider, and a short-circuit terminal is provided to either the lock verification slider or the first connector housing so that it faces the pair of engagement detection terminals. The pair of engagement detection terminals and the short-circuit terminal make up a connector engagement detection circuit. When the two connector housings are connected completely and the lock verification slider is advanced, the pair of engagement detection terminals and the short-circuit terminal are brought into contact with each other, completing the connector engagement detection circuit to indicate the full engagement of the mating connector housings.
A connector engagement detecting apparatus comprising: a first connector housing with a resilient lock arm; a second connector housing with an engagement portion that cooperates with the resilient lock arm of the first connector housing, said first and second connector housings being adapted to be joined together; a lock verification slider mounted to the first connector housing, said lock verification slider having a lock detection arm and being able to be advanced to a position where one end of said lock detection arm extends beyond said engagement portion only when the two connector housings are completely connected; a pair of engagement detection terminals provided to one of said first connector housing and said lock verification slider; and a short-circuit terminal provided to the other one of said lock verification slider and said first connector housing so that said short-circuit terminal faces the engagement detection terminals and, when the lock verification slider is advanced to said position, comes into contact with the engagement detection terminals.
