Abstract: PROBLEM TO BE SOLVED: To provide a connector having a simple structure, preventing a reduction of a mounting density, and allowing a front operation for engaging/ disengaging one connector with/from another connector. SOLUTION: By pressing a button 24, a turn lever 22 turns clockwise about a fulcrum 21A, thereby engaging a cable side connector 1 with a board side connector 11. In the engaged state, though an expanding force (restoring force) of a coil spring 25 is applied, since a large number of socket contacts of the cable side connector 1 are engaged with a large number of contacts of the board side connector 11, the cable side connector 1 is not disengaged from the board side connector 11. By pulling the button 24, the cable side connector 1 disengages from the board side connector 11 through a translation lever 23 and the turn lever 22. In other words, the engaging/disengaging operations are allowed on a front face.
