Abstract

Abstract An electrical connector is encapsulated with a uniform thickness of a transparent insulating material, preferably a clear PVC. The transparent insulating covering permits visual inspection of wires inserted into the connector before tightening the set screws to insure proper installation of the wire. Clarity of the insulating material over the entire connector is achieved by using the injection molding process, which also results in a uniform thickness of the insulating material over the body of the connector as well as cylindrical extensions for the wire and set screw openings.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 190 words
In a method of encapsulating an electrical connector which includes a body member of electrically conductive material, a plurality of wire receiving openings formed in the body member, and a plurality of threaded openings formed in the body member and provided with set screws for securing wires inserted into the wire receiving openings, the method comprising the steps of placing a threaded cylindrical mold-pin that is provided with a shoulder of larger diameter than the threaded opening into each threaded opening of the connector, with the shoulder in contact with the body member to provide a tight seal, placing a cylindrical mold-pin that is provided with a shoulder of larger diameter than the wire receiving opening into each wire receiving opening of the connector, with the shoulder in contact with the body member to provide a tight seal, and providing a mold around the body member and mold-pins, p1 the improvement comprising injecting an encapsulating material into said mold to form a transparent covering over the body member with each of the openings in the body member being free of encapsulating material but provided with a cylindrical sleeve extending therefrom.
Claim 2
Dependent Claim 190 words
In a method of encapsulating an electrical connector which includes a body member of electrically conductive material, a plurality of wire receiving openings formed in the body member, and a plurality of threaded openings formed in the body member and provided with set screws for securing wires inserted into the wire receiving openings, the method comprising the steps of placing a threaded cylindrical mold-pin that is provided with a shoulder of larger diameter than the threaded opening into each threaded opening of the connector, with the shoulder in contact with the body member to provide a tight seal, placing a cylindrical mold-pin that is provided with a shoulder of larger diameter than the wire receiving opening into each wire receiving opening of the connector, with the shoulder in contact with the body member to provide a tight seal, and providing a mold around the body member and mold-pins, p1 the improvement comprising injecting an encapsulating material into said mold to form a transparent covering over the body member with each of the openings in the body member being free of encapsulating material but provided with a cylindrical sleeve extending therefrom.
Claim 3
Dependent Claim 14 words
In the method of claim 1 wherein said encapsulating material is a clear PVC.
Claim 4
Independent Claim 214 words
A method of encapsulating an electrical connector which includes a body member of electrically conductive material, a plurality of wire receiving openings formed in the body member, and a plurality of threaded openings formed in the body member and provided with set screws for securing wires inserted into the wire receiving openings, the method comprising the steps of placing a threaded cylindrical mold-pin that is provided with a shoulder of larger diameter than the threaded opening into each threaded opening of the connector, with the shoulder in contact with the body member to provide a tight seal, installing the threaded cylindrical mold-pin on an injector plate of an injection molding machine, forming a die that conforms to the shape of the electrical connector, positioning a cylindrical mold-pin in the die, placing a cylindrical mold-pin that is provided with a shoulder of larger diameter than the wire receiving opening into each wire receiving opening of the connector, with the shoulder in contact with the body member to provide a tight seal, as the die is closed, and injecting an encapsulating material into said mold to form a transparent covering over the body member with each of the openings in the body member being free of encapsulating material but provided with a cylindrical sleeve extending therefrom.
Claim 5
Independent Claim 214 words
A method of encapsulating an electrical connector which includes a body member of electrically conductive material, a plurality of wire receiving openings formed in the body member, and a plurality of threaded openings formed in the body member and provided with set screws for securing wires inserted into the wire receiving openings, the method comprising the steps of placing a threaded cylindrical mold-pin that is provided with a shoulder of larger diameter than the threaded opening into each threaded opening of the connector, with the shoulder in contact with the body member to provide a tight seal, installing the threaded cylindrical mold-pin on an injector plate of an injection molding machine, forming a die that conforms to the shape of the electrical connector, positioning a cylindrical mold-pin in the die, placing a cylindrical mold-pin that is provided with a shoulder of larger diameter than the wire receiving opening into each wire receiving opening of the connector, with the shoulder in contact with the body member to provide a tight seal, as the die is closed, and injecting an encapsulating material into said mold to form a transparent covering over the body member with each of the openings in the body member being free of encapsulating material but provided with a cylindrical sleeve extending therefrom.
Claim 6
Dependent Claim 15 words
In the method of claim 1 wherein said transparent covering has a uniform minimum thickness.
Claim 7
Dependent Claim 15 words
In the method of claim 3 wherein said transparent covering has a uniform minimum thickness.
Claim 8
Dependent Claim 14 words
In the method of claim 3 wherein said encapsulating material is a clear PVC.
