Description of the Related Art As a conventional connector lock guarantee mechanism, a connector lock guarantee mechanism as shown in FIG. 8 has been proposed in Japanese Utility Model Laid-Open No. 1-165582. In the lock assurance mechanism of the connector shown in FIG. 8, in order to ensure the fitting of the male housing M and the female housing F, the lock assurance member M 1 is always mounted in one housing in a provisionally engaged state. When the male housing M and the female housing F are fitted together, the lock ensuring member M 1 moves from the temporary engagement position to the housing to the main engagement position to prevent the displacement of the lock arm a that locks the male and female housings. Both housings are kept locked.

とを検知することができる。When the male housing M and the female housing F are in the half-fitted state, as shown in FIGS. 9 and 10,
Since the disengagement drive rod b provided in the female housing F does not function to push up the flexible locking piece c of the lock ensuring member M 1 , the free end c 1 of the flexible locking piece c is locked by the lock arm a. Since it comes into contact with the engagement protrusions d provided on both sides of the rising base of the lock securing member M 1 cannot be pushed into the male housing M. Therefore, by confirming the state in which the lock ensuring member M 1 cannot be pushed in, it is possible to detect that the fitting of the two housings is incomplete.

When the detection part f and the detection protrusion e come into contact with each other in the half-fitted state of the housings, the lock-fitting member M 1 ′ cannot enter any more, so that the half-fitted state can be detected. When a large amount of pressing force is required for fitting, an excessive force acts on the abutting portion between the detecting portion f and the detecting protrusion e even in the semi-fitting state due to the pressing force. Te, as shown in FIG. 12, the locking arm a 'and the flexible locking piece c' is bent upward, the flexible locking piece c 'free end c 1'

に阻止される。By providing the detecting projection 14 with the inclined surface 15, the female and male housings F and M are half-fitted without providing the detecting surface 5c of the lock arm 5 with the inclined surface 6 as in the above embodiment. In this state, when an excessive pressing force acts on the lock ensuring member M 2 , the detection portion 5c of the lock arm 5 comes into contact with the inclined surface 15 of the detection protrusion 14, and the operation of the inclined surface 15 causes the lock arm 5 to descend. Because the force in the direction of
As in the case of the above embodiment, the lock arm 5 does not bend upward, and the lock ensuring member M 2 is reliably prevented from entering due to an error.
