Abstract

An open wedge socket for a cable or the like includes a wedge having a peripheral surface for engaging the cable, a housing including an outwardly opening channel for receiving the wedge and cable, and an interference member having a sliding fit on the housing to capture the wedge and cable in the channel. The channel provides a first working surface for engaging the cable and the interference member provides a second working surface for engaging the cable. The housing includes shoulders providing first camming surfaces and the interference member includes flanges providing second camming surfaces. When the interference member slides onto the housing it is drawn toward the channel to constrict one end of the channel and capture the wedge and cable between the first and second working surfaces.

Claims

1. An apparatus for gripping a bight of a cable or the like, comprising

a housing, the housing including a channel for receiving the bight of the cable, the channel providing a first working surface,

an interference member, the interference member including a second working surface, and

camming means providing a sliding fit between the interference member and the housing so that the first and second working surfaces are in opposed relationship to each other, the camming means including a first camming surface on the housing and a second camming surface on the interference member which when engaged move the two working surfaces toward each other to progressively narrow the channel as the interference member is cammed inwardly and capture the bight of the cable therebetween.

2. The apparatus of claim 1 wherein the camming means includes a shoulder on the housing providing the first camming surface and a flange on the interference member providing the second camming surface.

3. An apparatus for gripping a cable or the like, comprising:

a wedge having a surface for engaging the cable,

a housing, the housing including an outwardly opening channel for receiving the wedge and the cable, the channel providing a first working surface,

an interference member, the interference member including a second working surface, and

camming means providing a sliding fit between the interference member and the housing, the camming means including a first camming surface on the housing and a second camming surface on the interference member which when engaged move the two working surfaces toward each other to progressively narrow the channel as the interference member is cammed inwardly and capture the wedge and cable in the channel between the first and second working surfaces.

4. The apparatus of claim 3 wherein the first camming surface lies in a first plane, and the second working surface lies in a second plane at an acute dihedral angle with respect to the first plane.

5. The apparatus of claim 3 wherein the camming means includes a shoulder on the housing providing the first camming surface and a flange on the interference member providing the second camming surface.

6. The apparatus of claim 5 wherein the housing has a longitudinal axis and the shoulder is inclined with respect to the longitudinal axis of the housing so that the interference member moves at angle with respect to the longitudinal axis of the housing to constrict the channel and is drawn inward against the wedge and cable by the first and second camming surfaces.

7. The apparatus of claim 6 wherein the flange on the interference member includes an inturned lip providing the second camming surface in opposed spaced relationship to the second working surface;

the second camming surface being inclined at the same acute dihedal angle as the first camming surface with respect to the second working surface.

8. A method of attaching a socket to the free end of a cable or the like, comprising the steps of:

placing a bight of the cable on the periphery of a wedge,

positioning the cable-bearing wedge in an open channel within the socket,

sliding a top member over the open channel at an acute angle with respect to the longitudinal axis of the channel, and camming the top member inwardly toward the channel to progressively narrow the channel to capture the cable-bearing wedge between a bottom surface of the channel and a surface of the top member.
