Abstract

Abstract A first connector housing is 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.
