ABSTRACT:
The rotary plate of the cam member is formed with cam grooves symmetrical about the rotating shaft of the rotary plate. The rotating shaft has a rotary retainer plate at its end. A pair of mating housings are each provided with a cam follower pin that engages with the respective cam grooves. One of the housings is formed with a pin guide groove that guides the rotating shaft of the cam member and the cam follower pin of the other housing. At the dead end of the pin guide groove is formed an enagement completion opening from which the rotary retainer plate can be pulled out when the both housings are completely engaged together. The fact that the mating female and male housings are engaged or disengaged by the rotating operation of the cam member and that the cam member is allowed to be removed only when the mating housings are completely engaged, prevents any incomplete engagement of the housings and assures highly reliable electrical connections while at the same time requiring a small operating force during the engagement process.
