Abstract

A pivoting member attached to a female housing, which is capable of receiving a complementary male housing. A resilient elastic member, preferably U-shaped, is disposed between an operating portion toward the rear of pivoting member and the female housing. The bend of the U-shape is positioned toward the pivot. The resilient member 50 is hidden behind the pivoting member and is located within the housing so that it does not get caught by parts of other connectors shipped with it in a single container.

Claims

1. An electrical connector comprising a male housing and a female housing, said male housing adapted for insertion along a path into said female housing in an insertion direction, whereby at least one terminal in said male housing is brought into electrical contact with a corresponding terminal in said female housing,

a pivoting arm mounted on one of said female housing and said male housing, a cam on said arm, said arm adapted to pivot about a pivot point and having a locking position, wherein said cam is in said path, and an open position, wherein said cam is not in said path,

an actuating member on another of said male housing and said female housing, said actuating member adapted to contact said cam at a surface thereof as said male housing is inserted into said female housing,

a resilient member disposed entirely within said one housing and bearing against said arm at a bearing point, said pivot point being between said bearing point and said cam, said resilient member urging said arm toward said locking position, said resilient member having a bent portion and two legs, one of said legs bearing against said arm at said bearing point and another of said legs bearing against an internal surface of a wall of said one housing.

2. The electrical connector of claim 1 wherein said bent portion is concave toward said pivot point.

3. The electrical connector of claim 1 wherein said cam comprises an inclined surface angled inwardly in said insertion direction, a reverse incline angled outwardly in said insertion direction, and an apex therebetween.

4. The electrical connector of claim 3 wherein a rear face of said cam in said insertion direction is substantially perpendicular to said direction.

5. An electrical connector comprising a male housing and a female housing, said male housing adapted for insertion along a path into said female housing in an insertion direction, whereby at least one terminal in said male housing is brought into electrical contact with a corresponding terminal in said female housing,

a pivoting arm mounted on one of said female housing and said male housing, a cam on said arm, said arm adapted to pivot about a pivot point and having a locking position, wherein said cam is in said path, and an open position, wherein said cam is not in said path,

an actuating member on another of said male housing and said female housing, said actuating member adapted to contact said cam at a surface thereof as said male housing is inserted into said female housing,

a resilient member disposed entirely within said one housing and bearing against said arm at a bearing point, said pivot point being between said bearing point and said cam, said resilient member urging said arm toward said locking position,

a pair of projecting walls with a space therebetween on an external surface of said other of said male housing and said female housing, said pivoting arm being located in said space when said male housing is secured in said female housing.

6. The electrical connector of claim 5 wherein an outer surface of said pivoting arm is substantially flush with said pair of projecting walls.
