Abstract

A plug assembly comprises a molded plug first and second ends, front and back surfaces, and extending along a longitudinal axis. The plug includes a socket extending from the front surface at least partially through the plug along a width axis. The socket defines at least one hole extending at least partially therethrough. The plug assembly also includes a retainer at least partially molded within the plug, with a first end adjacent the first end of the plug and a second end adjacent the second end of the plug. Additionally, the plug assembly includes a first wire set connected to the socket within the plug. The plug assembly further includes a first securing member securing the first wire set to the retainer within the plug, adjacent the first end of the retainer, to hold the first wire set in a fixed position within the plug during the overmolding process.

Claims

1. A plug assembly, comprising:

a molded plug having opposing first and second ends and opposing front and back surfaces, the plug extending along a longitudinal axis, wherein the plug includes a socket extending from the front surface at least partially through the plug along a width axis, the socket defining a plurality of socket holes extending at least partially therethrough;

a retainer at least partially molded within the plug, the retainer having a first end adjacent the first end of the plug and a second end adjacent the second end of the plug;

a first wire set extending into the plug and connected to the socket within the plug; and

a first securing member securing the first wire set to the retainer within the plug, adjacent the first end of the retainer, to hold the first wire set in a fixed position within the plug during the overmolding process.

2. The assembly of claim 1, comprising a second wire set extending into the plug and connected to the socket within the plug, and a second securing member securing the second wire set to the retainer within the plug, adjacent the second end of the retainer, to hold the second wire set in a fixed position within the plug during the overmolding process.

3. The assembly of claim 1, wherein the first wire set includes two wires, the second wire set includes two wires, and the socket defines four socket holes, each socket hole being associated with one of the wires.

4. The assembly of claim 1, wherein the retainer is composed of a plastic material and the plug is composed of polyvinylchloride.

5. The assembly of claim 1, wherein each of the first and second securing members is selected from the group consisting of a tie, a section of tape, a crimp and a clip.

6. The assembly of claim 1, comprising first and second mounting bolts configured to be received in the first and second mounting holes to mount the plug.

7. The assembly of claim 1, wherein the width axis of the first mounting hole, the width axis of the second mounting hole and the width axis of the socket are substantially parallel, and wherein the longitudinal axis of the retainer is aligned with the longitudinal axis of the plug and perpendicular to the width axes of the first mounting hole, the second mounting hole, and the socket.

8. A molded plug having opposing first and second ends and opposing front and back surfaces, the plug extending along a longitudinal axis, wherein the plug includes a socket extending from the front surface at least partially through the plug along a width axis, the socket defining at least one socket hole extending at least partially therethrough;

a retainer at least partially molded within the plug, the retainer having a first end adjacent the first end of the plug and a second end adjacent the second end of the plug;

a first wire set extending into the plug and connected to the socket within the plug; and

a first securing member securing the first wire set to the retainer within the plug, adjacent the first end of the retainer, to hold the first wire set in a fixed position within the plug during the overmolding process;

wherein the retainer includes a first bushing adjacent the first end of the retainer, defining a first mounting hole in the plug extending along a width axis, wherein the retainer includes a longitudinal portion extending from the first bushing along a longitudinal axis, wherein the bushing includes front and back surfaces aligned and substantially co-planar with the front and back surfaces of the plug.

9. A molded plug having opposing first and second ends and opposing front and back surfaces, the plug extending along a longitudinal axis, wherein the plug includes a socket extending from the front surface at least partially through the plug along a width axis, the socket defining at least one socket hole extending at least partially therethrough;

a retainer at least partially molded within the plug, the retainer having a first end adjacent the first end of the plug and a second end adjacent the second end of the plug;

a first wire set extending into the plug and connected to the socket within the plug; and

a first securing member securing the first wire set to the retainer within the plug, adjacent the first end of the retainer, to hold the first wire set in a fixed position within the plug during the overmolding process;

wherein the retainer includes a first bushing adjacent the first end of the retainer, defining a first mounting hole in the plug extending along a width axis, and a second bushing adjacent the second end of the retainer, defining a second mounting hole extending along a width axis, wherein the retainer includes a reduced-height longitudinal portion extending between the first and second bushings along a longitudinal axis, wherein each of the bushings includes front and back surfaces aligned and substantially co-planar with the front and back surfaces of the plug, respectively.
