Abstract: A fitting operation lever includes rotation fulcrum holes rotationally engaged with boss portions on a first connector housing, boss guiding grooves enabling the boss portions and the rotation fulcrum holes to be engaged with or disengaged, flexible arms extending from lever main bodies so as to be superposed on outer surfaces of an outer cylindrical wall portion of a second connector housing a fitting starting time of the connector housings, and action point projecting portions provided at distal end sides of the flexible arms so as to be engaged with lever locking holes in the outer cylindrical portion at the fitting starting time. The engagement of the action point projecting portions with the lever locking holes can be released by deflecting and displacing the distal end sides in a direction in which the distal end sides move away from the outer surfaces.

Abstract: After first and second connector housings have been aligned at an engagement initiating position, a lever is rotatably engaged with the first connector housing. The lever is provided with boss parts slidable in boss guiding grooves of the second connector housing and boss retracting grooves of the first connector housing. When the boss parts slide with rotation of the engagement operating lever, the connector housings move in an engaging direction such that the boss guiding grooves may be overlapped on the boss retracting grooves. By further rotating the lever, after the mutual engagement between the connector housings has been completed, the boss parts are released from the boss guiding grooves and the boss retracting grooves with the aid of slopes, thus enabling the lever to be detached from both the connector housings.

Abstract: A second connector housing (20) includes shaft guiding slots (22) in which lever supporting shafts (11) of a first connector housing (10) are fitted movably along a direction in which the connector housings are fitted with each other, and action receiving shafts (23) at a pair of opposed side walls (21a) of an outer sheath wall part (21) with which the first connector housing (10) is fitted, and a fitting lever (30) which is pivotably installed to the first connector housing includes shaft engaging slots (32) which the lever bodies (31) are formed with and have a straight line shape so that both the lever supporting shafts (11) which are inserted through the shaft guiding slots (22) and the action receiving shafts (23) are embedded, and a force point part (33) which receive an operating force when the lever bodies (31) are pivoted around the lever supporting shafts (11).
