MULTIPOLAR CONNECTOR REQUIRING LITTLE ATTACHING-DETACHING FORCE

摘要

PURPOSE:To facilitate the attaching and detaching operation to be performed in a narrow space by causing a slider, which constitutes a cam mechanism for engaging and disengaging two housings, to be ordinarily installed on either one of the two. CONSTITUTION:A projected housing 2 is inserted into the recessed body 7 of a recessed housing 1. The insertion is carried on until the cam follower 21 of a temporarily locked slider 3 reaches the back wall of the inlet part 25a of a guiding groove 25. When the slider 3 is then moved to the left, the housing 2 approaches the housing 1 by means of the groove 25, which is engaged with the follower 21, and comes in sliding contact with a gentle slope of the groove 25 so that an engagement is completed with only a small force. If the operation of the slider 3 at the time of detaching is performed in such a manner that the central part of a pressing part 18, that is, the middle part between rails 11,12, is pressed with the tip of a finger, the angular moment is little and a wasteful force is unnecessary. Since the slider 3 is installed on the housing 1 in advance, a space for the installation thereof is not required specifically. Thereby, the attaching and detaching operation in a limited narrow space is made possible, and the force required for the attaching and detaching operation can also be made smaller.
