Abstract

A lever 22 is pivotally supported on a male connector 21 by bosses 27, and provisionally-retaining abutment piece portions 38 are formed respectively at lower portions of side walls 28 of the lever 22 at a rear end portion thereof. Provisionally-retaining blocks 37 are formed at a lower portion of the male connector 21 at a rear end portion thereof, and the provisionally-retaining abutment piece portions 38 are abutted respectively against the provisionally-retaining blocks 37 in an initially-fitted condition. Cancellation plates 39 for canceling the abutting engagement of the provisionally-retaining abutment piece portions 38 with the provisionally-retaining blocks 37 are formed within a hood portion 32 of a female connector 23. With this construction, when the male connector 21 is to be fitted into the hood portion 32, engagement projections 30 can be easily inserted into guide grooves 34, respectively. Only the provisionally-retaining abutment piece portions 38 need to have resiliency, and therefore it is not necessary to increase the wall thickness of the lever 22, and also the pivotal movement of the lever 22 can be easily effected.

A lever fitting-type connector comprising:

a first connector mateable with a second connector;
a lever pivotally supported on said first connector at an intermediate portion thereof intermediate opposite ends of said lever, said lever including an operating portion formed at one end portion of said lever and an engagement portion provided at an opposite end portion of lever with said intermediate portion being disposed between said operating portion and said engagement portion, said engagement portion engaging said second connector, said lever being pivotally moved by pushing said operating portion with said intermediate portion serving as an application point to fit said first connector into said second connector, said lever including:
provisionally-retaining abutment piece portions provided at said one end portion of said lever and beneath said operating portion, which have resiliency and are held in abutting engagement with said first connector in an initial condition;
and
