Abstract
A coupling detecting structure includes: a first and a second connector housings accommodating terminals; a lever having an engaging portion engaging with an engaging portion of the second connector housing; and a detecting circuit detecting the coupling state of both of the connector housings. When the lever is revolved with respect to the engaging section between the engaging portion of the lever and the engaging portion of the second connector housing, both of the connector housings are coupled. In the construction, a pair of conductive members are provided on the second connector housing; a conductive member which comes into a contact with the pair of the conductive members only when both the connector housings are coupled with each other is provided on the lever; and the three conductive members constitute the detecting circuit.
