Patent ID: 6860748

Claim:
A connector comprising at least two springs provided with locking projections, respectively, and a control mechanism which controls positions of the locking projections, the control mechanism comprising a single button and a cam mechanism, which is coupled to the single button and has two cam portions arranged close to the two springs, comprising in a first direction an opening through which the single button partially projects outside the connector, wherein: the two springs are arranged parallel to each other in a second direction perpendicular to the first direction; wherein the cam mechanism includes two slanting side portions as the cam portions, whose surfaces lie diagonally across both the first and the second directions and which add the forces to the two springs, respectively, in the second direction when the single button is pushed down in the first direction so that, when the single button is operated, the two cam portions add forces corresponding to movement of the single button to the two springs simultaneously to elastically deform the two springs and thereby to control the positions of the locking projections, the locking projections being arranged parallel to each other in the second direction; and the cam mechanism being coupled to the single button within the connector so that the two cam portions are arranged close to the two springs in the second direction.
