Abstract
Abstract A female connector and a male connector engageable with each other are paired. Fixing shafts are projected from both lateral sides of the male connector. The female connector has a retaining lever being pivotable about pivots arranged on both lateral sides thereof. Rail portions are arranged on a front surface of the lever, each rail portion having a predetermined surface of curvature. When the male connector is inserted into the female connector, shaft portions of the fixing shafts are abutted against the rail portions and bias the rail portions, so that the surfaces of curvature produce resisting forces, each having a component for pivoting the lever.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
184 words
A lever-type connector comprising: a pivotal retaining lever provided on a first connector; a second connector fitted relative to said first connector by pivotal movement of said retaining lever, the second connector having a lever lock portion for retaining said retaining lever and having a connection end for connection with said first connector, said lever lock portion including: an elastic lock plate extending from an outer surface of a housing of said second connector; a lock release portion extending from a free end of said elastic lock plate, said lock release portion being displaceable in accordance with elastic deformation of said elastic lock plate; upstanding side walls provided respectively on opposite sides of said elastic lock plate; and a forward-fall prevention member mounted on and extending between said side walls, and disposed at a front position within the range of flexing of said lock release portion for limiting movement of the lock release portion in a direction towards said connection end, whereby when the elastic lock plate is elastically deformed, an upper surface of said lock release portion strikes against said forward-fall prevention member.
Claim 2
Dependent Claim
184 words
A lever-type connector comprising: a pivotal retaining lever provided on a first connector; a second connector fitted relative to said first connector by pivotal movement of said retaining lever, the second connector having a lever lock portion for retaining said retaining lever and having a connection end for connection with said first connector, said lever lock portion including: an elastic lock plate extending from an outer surface of a housing of said second connector; a lock release portion extending from a free end of said elastic lock plate, said lock release portion being displaceable in accordance with elastic deformation of said elastic lock plate; upstanding side walls provided respectively on opposite sides of said elastic lock plate; and a forward-fall prevention member mounted on and extending between said side walls, and disposed at a front position within the range of flexing of said lock release portion for limiting movement of the lock release portion in a direction towards said connection end, whereby when the elastic lock plate is elastically deformed, an upper surface of said lock release portion strikes against said forward-fall prevention member.
Claim 3
Dependent Claim
77 words
A lever-type connector as claimed in claim 1, further comprising: rearward-fall prevention members formed on and projecting from an inner surface of said of said side walls for limiting movement of the lock release portion in a direction away from said connection end, the rearward-fall prevention member extending along an axis of said housing, whereby a lower surface of said lock release portion strikes against said rearward-fall prevention members upon elastic deformation of said elastic lock plate.
Claim 4
Dependent Claim
23 words
A lever-type connector as claimed in claim 1, wherein a retaining hole is formed in a central portion of said elastic lock plate.
Claim 5
Dependent Claim
23 words
A lever-type connector as claimed in claim 1, wherein an upper surface of said lock release portion is formed in a step configuration.
