Abstract A connector is constructed to prevent an electronic circuit from being erroneously activated due to electric current induced when a female connector housing and a male connector housing are disconnected from each other, and moreover, ensure that a locked connection detecting circuit is activated when both the connector housings are connected to each other in the locked state. The connector includes a male connector housing having a flexible locking arm and chambers for respectively receiving a plurality of terminals; a female connector housing having an engagement member for engaging the flexible locking arm of the male connector housing; a lock detecting member for detecting a locking condition of the male and the female connector housings by releasing the lock detecting member from the male connector housing when the female connector housing is connected to the male connector housing; and a short circuit member for short-circuiting terminals accommodating the receiving chambers of the male connector housing when the male connector housing and the female connector housing are in a disconnected state, and for short-circuiting the terminals of the female connector housing to complete a lock condition detecting circuit when the male connector housing and the female connector housing are in a connected and locked condition.
A connector comprising: a male connector housing having a flexible locking arm and chambers for respectively receiving a plurality of first terminals; a female connector housing having an engagement member for engaging the flexible locking arm of the male connector housing, a plurality of second terminals, and a pair of detecting circuit terminals; a lock detecting member for detecting a locked condition of the male and female connector housings when the lock detecting member is released from the male connector housing upon connection of the female connector housing to the male connector housing with pairs of the first and second terminals in engaged relation; and a short circuit member for short-circuiting the first terminals accommodated in the chambers of the male connector housing when the male connector housing and the female connector housing are in a disconnected state, and for short-circuiting the pair of detector circuit terminals in the female connector housing when the male connector housing and the female connector housing are in the locked condition.

Claim 3
Dependent Claim
122 words
A connector as defined in claim 1, wherein the lock detecting member includes: a locking connection detection member fitted to an end portion of the male connector housing, the locking connection detection member being connected to the male connector housing when the male connector housing and the female connector housing are in the disconnected state, the locking connection detection member being provided with engagement pieces formed on an end portion of the locking connection detecting member; and engagement releasing projections provided at an end portion of the female connector housing, the engagement releasing projections engaging the engagement pieces to disconnect the locking connection detection member from the male connector housing when the male connector housing is connected to the female connector housing.
