The electric contact part has a substantially conical nose and is formed by squeezing one end of the conductive pipe in such a manner that the diameter of the one end is gradually reduced frontward. The wire crimping part has such an inner diameter as to allow a wire to be inserted thereinto.

Abstract: A partial-fitting prevention connector which can be positively fitted relative to a mating connector, and is prevented from being only partially fitted relative to the mating connector. When the partial-fitting prevention connector (1) is fitted relative to a mating connector (2), a retaining member (25), formed on a lock member (22), abuts against a retaining projection (34) formed on the mating connector (2), and the lock member (22) is pushed against the bias of a spring (23) in a rearward direction away from the mating connector. After the lock member has moved a predetermined distance, lock release projections (26a and 26b), formed on the lock member (22), slide over lock release projections (42a and 42b) formed on a support structure (41), thereby pivotally moving the lock member (22).

In the second connector housing, a pair of engagement detecting metal terminals are provided in confrontation with the shorting contactor. When the first and second connector housings are incompletely engaged with each other, the shorting contactor is not contact with the engagement detecting metal terminals by the displacement of elastic contact plate which is due to the displacement of the flexible locking arm.

Abstract: A connector engaging structure which prevents male and female connectors from being insufficiently engaged with each other, and which positively prevents the connector housing from being damaged. The connector engaging structure 1 is designed as follows. In engaging a second connector 3 with a first connector 2, a cantilevered arm 44 formed in an outer housing, which is a part of the second connector, is locked to a locking protrusion 16 of the first connector. Next, a locking arm 25 forming an inner housing 21, which is a part of the second connector 3, is engaged with an engaging groove 15 formed in the first connector 2. With the outer housing 22 moved by the elastic force of a spring member 35, the lock arm 25 is held down so that the first and second connectors are completely engaged with each other.
