Abstract
Abstract A slider is mounted on a housing of one of male and female connectors to be fitted together, and is urged in one direction by a spring, and flexible arms and a lock arm are formed integrally with this slider. Second engagement projections, formed on a housing of the female connector, push the flexible arms, respectively, and are engaged respectively with the flexible arms when the two connectors are fitted together. A retaining projection for retaining the lock arm is formed on that housing. In a half-fitted condition, the second engagement projections are not engaged respectively with the flexible arms, and the female connector is pushed back by the spring, so that the half-fitted condition can be detected. The lock arm is engaged with the retaining projection, and also the flexible arms are engaged respectively with the second engagement projections, thereby preventing the two connectors from being accidentally disengaged from each other.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
96 words
A half-fitting prevention connector, comprising: a first connector which is to be fitted to a second connector, said first connector including a first projection; a slider mounted on said first connector for movement in a fitting direction and a retracting direction; and a resilient member provided on said first connector for urging said slider in said fitting direction; wherein, when said first connector is fitted to said second connector, (1) said second connector moves said slider in said retracting direction against the influence of said resilient member, and (2) said first projection elastically deflects said slider.
Claim 2
Dependent Claim
96 words
A half-fitting prevention connector, comprising: a first connector which is to be fitted to a second connector, said first connector including a first projection; a slider mounted on said first connector for movement in a fitting direction and a retracting direction; and a resilient member provided on said first connector for urging said slider in said fitting direction; wherein, when said first connector is fitted to said second connector, (1) said second connector moves said slider in said retracting direction against the influence of said resilient member, and (2) said first projection elastically deflects said slider.
Claim 3
Dependent Claim
114 words
The half-fitting prevention connector according to claim 1, wherein said slider comprises a flexible arm which is elastically deflectable; wherein, when said first connector is fitted to said second connector, (1) a second projection of said second connector abuts said flexible arm and moves said slider in said retracting direction against the influence of said resilient member, (2) while said slider moves in said retracting direction, said first projection of said first connector elastically deflects said flexible arm to misalign said flexible arm with respect to said second projection, and (3) said resilient member moves said slider in said fitting direction, such that said flexible arm retains said second projection of said second connector.
Claim 4
Dependent Claim
36 words
The half-fitting prevention connector according to claim 2, wherein said flexible arm includes an inwardly-directed engagement pawl formed at a distal end thereof, said engagement pawl having a tapered surface formed on an inner side thereof.
Claim 5
Dependent Claim
32 words
The half-fitting prevention connector according to claim 3, wherein said first projection includes a tapered surface upon which said engagement pawl of said flexible arm slides to elastically deflect said flexible arm.
Claim 6
Dependent Claim
38 words
The half-fitting prevention connector according to claim 3, wherein, when said flexible arm retains said second projection, said tapered surface of said engagement pawl abuts against a corresponding tapered surface provided on a surface of said second projection.
Claim 7
Dependent Claim
52 words
The half-fitting prevention connector according to claim 1, wherein said slider comprises a pivotally moveable lock arm having a retaining portion; wherein, when said first connector is fitted to said second connector, a retaining projection of said second connector pivots said lock arm, such that said retaining portion retains said retaining projection.
