Insertion and withdrawal connector apparatus, structure of remote controlling engagement and separation thereof, and connecting frame block structure for insertion and withdrawal connector apparatus or the like

An insertion and withdrawal connector apparatus comprising a connector receiving body which has a pair of parallel frames, a pair of frame blocks positioned at both end portions of said parallel frames, and a plurality of partition members, each of said partitions having two sides surfaces, and which is constituted in such a manner that one connector and one mating connector are received in each of a plurality of receiving chambers partitioned by said frames, said mating connector having two side surfaces, said frame blocks, and said partition members, comprising:

• each of said partition members having a paid of lances with a spring characteristic, each of said partition members having one of said lances on each of its side surfaces;
• each of said connectors having a pair of interlocking groove portion, each of said connectors having one of said interlocking groove portions on each of it is side surfaces;
• each of said connectors being prevented from moving in a withdrawal direction by the fact that each of said lances interlocks with said interlocking groove portion when each of said connectors is inserted into each of said receiving chambers to a midway position of engagement, and
• a convex portion being formed on the side surface of each of said connectors and is being brought into contact with an end surface of each of said partition members whereby each of said connectors is prevented from moving in an insertion direction beyond an engagement position between each of said connectors and each of said mating connectors.
