ABSTRACT:
A connector includes first terminals that are mounted on a vehicle-side housing in a projected manner, and second terminals that are mounted on a power source-side housing. A first contact portion provided at one end of each of the second terminals is so disposed as to be contacted with a respective one of the first terminals, and a first opening/closing switch of a detection circuit is constituted therebetween. A second contact portion provided at the other end of the second terminal is disposed in facing relation to a contact plate affixed to a lower surface of a lock lever, and a second opening/closing switch is constituted therebetween. In a half-fitted condition, the first opening/closing switches are closed, but the second opening/closing switches are open, and therefore, the detection circuit has not yet been closed. When the complete fitting is achieved, a retaining pawl of the lock lever fits in a fitting hole, so that the contact plate is brought into contact with the second contact portions of the second terminals, thereby closing the second opening/closing switches, so that the detection circuit is closed.
