1. A lever connector comprising:
a first connector housing; a second connector housing which is fitted and connected with the first connector housing; and a fitting lever which is pivotably installed to the first connector housing as a lever member to reduce the operating force to fit and detach the first connector housing with and from the second connector housing, wherein the first connector housing includes lever supporting shafts which are respectively protruded from a pair of outer surfaces to support the fitting lever to be pivotable, the second connector housing includes:
an outer sheath wall part which is fitted with the outer circumference of the first connector housing,shaft guiding slots which are formed by cutting a pair of opposed side walls of the outer sheath wall part along a fitting direction of the connector housing, and in which, when the connector housings are fitted with each other, the lever supporting shafts are fitted movably along the fitting direction of the connector housings; andaction receiving shafts which are protruded from the outer surfaces of the side walls, where the shaft guiding slots are formed, and are located with a predetermined distance from the shaft guiding slots in a direction perpendicular to the fitting direction of the connector housings, the fitting lever includes:a pair of lever bodies which are arranged to be opposed to each other to sandwich the outer surfaces of the pair of side walls of the second connector housing where the shaft guiding slots are formed; anda force point part which receives an operating force to make the pair of lever bodies pivot around the lever supporting shafts, and the lever bodies include: first shaft introducing grooves which are formed to open at side edges at an insertion side to the outer surfaces of the pair of side walls of the second connector housing, and which introduce the lever supporting shafts, which are inserted through the shaft guiding slots, to first initial engaged positions when the pair of lever bodies are inserted and installed to the outer surfaces of the pair of side walls in an initial inclined state; second shaft introducing grooves which are formed to open at side edges at the insertion side to the outer surfaces of the pair of side walls of the second connector housing, and which introduce the action receiving shafts to second initial engaged positions when the pair of lever bodies are inserted and installed to the outer surfaces of the pair of side walls in the initial inclined state, pivoting fulcrum parts which are set at positions spaced a predetermined distance from the first initial engaged positions along an initial engaging straight line that is a straight line which passes the center of the lever supporting shafts and the center of the action receiving shafts while the first connector housing and the second connector housing are aligned at a fitting start position, and with which the lever supporting shafts are pivotably engaged, first communicating grooves which are formed to straightly link the first initial engaged positions and the pivoting fulcrum parts, and which introduce the lever supporting shafts at the first initial engaged positions to the pivoting fulcrum parts when the lever bodies are moved straightly along the initial engaging straight line, action receiving parts which are set at positions spaced a predetermined distance from the second initial engaged positions along the initial engaging straight line, and with which the action receiving shafts are engaged when the lever supporting shafts are moved to the pivoting fulcrum parts, second communicating grooves which are formed to straightly link the second initial engaged positions and the action receiving parts, and which introduce the action receiving shafts at the second initial engaged positions to the action receiving parts when the lever supporting shafts at the first initial engaged positions are moved to the pivoting fulcrum parts, first shaft detaching grooves which are provided adjacently to the first communicating grooves, have shapes corresponding to detachment moving traces which are different from installing moving traces when the fitting lever is pivotably installed to the first connector housing, and make the lever supporting shafts, which are located at the pivoting fulcrum parts, escape to the outside of the lever bodies with the movement of the fitting lever along the detachment moving traces, and second shaft detaching grooves which are provided adjacently to the second communicating grooves, have shapes corresponding to the detachment moving traces, and make the action receiving shafts, which are located at the action receiving parts, escape to the outside of the lever bodies with the movement of the fitting lever along the detachment moving traces. |
