ABSTRACT:
This invention relates to a connector engagement detecting apparatus having a compact checking structure. In the first connector housing A', a short-circuit contact piece 19 with an elastic contact strip 19c is provided as positioned on the side of a deflectable space for a resilient lock arm 14, a shirt-circuit contact portion 19c 3 of the elastic contact strip 19c being opposed and spaced out to a bottom wall of the deflectable space, further, an depressing portion 19d of the elastic contact piece 19c being extended above over the bottom wall and opposed to the resilient lock arm 14, thereby, the elastic contact piece 19c being deflected according to the deflection of the resilient lock arm 14, on a supporting frame 17 in the second connector housing B', a couple of terminal pins D"/D" for detecting engagement being provided to be opposed to the short-circuit contact piece, when the first connector housing A' and the second connector housing B' are incompletely engaged, the resilient lock arm 14 being deflected to deform the short-circuit contact piece 19C not to make contact with a couple of the terminal pins D"/D" for detecting engagement.
