Abstract
Abstract A lever 40 is pivotally mounted on a female connector housing 21 through support shafts 27. A split groove 28 is formed in a distal end of the support shaft so as to elastically deform this distal end to reduce a diameter thereof. A retaining larger-diameter portion 29 is formed on this distal end, and a slanting guide surface is formed on a distal end of this larger-diameter portion 29. The lever 40 has support shaft insertion holes 43 for receiving the support shafts 27, respectively. An inner surface of the support shaft insertion hole 43 is enlarged in a stepped manner to provide a reception recess 44 for receiving the retaining larger-diameter portion 29 of the support shaft 27, and the retaining larger-diameter portion 29 is embedded in the lever 40. It is provided a wire cover 60 which is slidable in a direction perpendicular to the direction of pivotal movement of the lever 40. An engagement pawl 51 of the lever 40 engages a hook portion 65 of the wire cover 60 to thereby lock the lever 40 in the fitting completion position. In this condition, when the wire cover 60 is slidingly moved, the locking is released, and also cam projections 63 of the wire cover 60 urge the lever 40 upwardly to slightly pivotally move the pivotal movement member toward the fitting-starting position, thus enabling the finger to be easily engaged with the lever 40.

Claim 7
Dependent Claim
155 words
A connector comprising: a first connector housing in which a plurality of terminals are mounted; a second connector housing in which a plurality of terminals are mounted, said second connector housing being fittable with said first connector housing; a support shaft insertion hole formed in said first connector housings; a fitting assistance member for fitting said first and second connector housings together and for disconnecting them from each other, said fitting assistance member having a support shaft to be pivotally mounted in said support shaft insertion hole; wherein said support shaft includes: a split groove in a distal end so that said distal end is elastically deformable to be reduced in diameter, and a retaining larger-diameter portion formed at said distal end portion of said support shaft which is inserted into a support shaft insertion hole, a diameter of said retaining larger-diameter portion being larger than an inner diameter of said support shaft insertion hole.
Claim 8
Dependent Claim
175 words
A connector comprising: a first connector housing in which a plurality of terminals are mounted; a second connector housing in which a plurality of terminals are mounted, said second connector housing being fittable with said first connector housing; a pivotal movement member mounted on said first connector housings, and operatable to be pivotally moved between a fitting-starting position and a fitting completion position, said pivotal movement member being pivotally moved to fit together said two connector housings and to disconnect from each other; an auxiliary member mounted on said first connector housing being displaceable in a direction intersecting to a direction of pivotal movement of said pivotal movement member; and a lock mechanism for engagement said pivotal movement member disposed in said fitting completion position with said auxiliary member to lock said pivotal movement member in said fitting completion position, said lock mechanism being provided on said auxiliary member and said pivotal movement member; wherein said auxiliary member is displaced to cause said lock mechanism to effect a locking operation and a lock release operation.
Claim 9
Dependent Claim
