Abstract

A connector includes a first housinng and a second housing fitted to each other. The first housing has an engaging portion and the second housing has an elastic lock arm. The front end in an inserting direction of the elastic lock arm is integally connected to the second housing. The elastic lock arm extends in the inserting direction, which rear end in the inserting direction forms a free end. A lock projection is integrally formed on the elastic lock arm. The lock projection engages the engaging portion to be depressed by the engaging portion when fitting the second housing to the first housing, and has a first sliding face sliding on the engaging portion when depressed by the engaging portion. The first sliding face is formed such that an inclination angle thereof is substantially the same as a maximum bending angle of the elastic lock arm. The lock projection has a second sliding face disposed on a front side of the first sliding face.

Claims

1. A connector comprising;

a first housing;

a second housing fitted to said first housing;

an engaging portion disposed in said first housing;

an elastic lock arm having a front end of which in an inserting direction is integrally connected to said second housing, said elastic lock arm extending in the inserting direction, a rear end of which in the inserting direction forms a free end; and

a lock projection integrally formed on said lock arm, engaging said engaging portion to be depressed by said engaging portion when fitting said second housing to said first housing, having a first sliding face sliding on said engaging portion when depressed by said engaging portion, said first sliding face formed such that an inclination angle of said first sliding face is substantially the same as a maximum bending angle of said elastic lock arm relative to the inserting direction;

said lock projection having a second sliding face disposed on a front side of said first sliding face.

2. A connector according to claim 1, wherein

said inclination angle of said first sliding face in the inserting direction is slightly larger than the maximum bending angle.

3. A connector according to claim 1, wherein

said inclination angle of said first sliding face in the inserting direction is slightly smaller than the maximum bending angle.
