Abstract
Abstract A connector for making an electrical connection to a threaded stud for power distribution applications such as transformer applications. A conductive connector threaded at one end to receive the stud is insulated with a protective jacket which mates with the stud bushing to enclose the connection. A set screw projects through the insulation into a threaded socket to bear against the stud when the set screw is tightened. The bearing surface may be a section of the wall of the body within the threaded area or may be an inset pressure pad, or plastic set screw tip. The free end of the connector may have a suitable connector for connection to a cable. A slideable insulating sleeve or boot fitted over the last mentioned connector may insulatingly cover the entire connection.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
149 words
A connector for making an electrical connection to a threaded conducting stud, the invention comprising: a terminal member of high current carrying capacity including a body having a suitably threaded socket for receiving the stud, a terminal end of said body extending therefrom, means for exerting compressive force on the stud mated within the body, said exerting means comprising a set screw, and an intermediate member disposed between the tip of said set screw and the body of a stud, and wherein said intermediate member responds to pressure from said set screw to cold flow between the threads of said stud, and wherein said intermediate member comprises a deformable member of greater surface than set screw diameter to provide contact with the stud greater than the area of the tip of said set screw, said deformable member comprised of material softer than said stud and than said set screw.
Claim 2
Dependent Claim
149 words
A connector for making an electrical connection to a threaded conducting stud, the invention comprising: a terminal member of high current carrying capacity including a body having a suitably threaded socket for receiving the stud, a terminal end of said body extending therefrom, means for exerting compressive force on the stud mated within the body, said exerting means comprising a set screw, and an intermediate member disposed between the tip of said set screw and the body of a stud, and wherein said intermediate member responds to pressure from said set screw to cold flow between the threads of said stud, and wherein said intermediate member comprises a deformable member of greater surface than set screw diameter to provide contact with the stud greater than the area of the tip of said set screw, said deformable member comprised of material softer than said stud and than said set screw.
Claim 3
Dependent Claim
59 words
A connector as claimed in claim 1, wherein said intermediate member comprises a blind, threaded socket in said body disposed toward and spaced from said stud socket for receiving said set screw, and wherein said intermediate member comprises a continuous, solid web of material of said body within the space between said set screw tip and said stud socket.
Claim 4
Dependent Claim
213 words
A connector for making an electrical connection to a threaded connecting stud extending from an enlarged conductive mounting the invention comprising: a terminal member of high current carrying capacity including a conductive body having a suitably threaded socket for receiving the stud, a water-proof, insulating flexible housing covering said body, a first opening in said housing for receiving said stud, a mouth of said opening cooperating with said insulating member for water-proofing the connection of said body to said stud, a terminal end of said body extending therefrom externally of said housing, a threaded socket in said body, means for exerting compressive force on the stud mated within the body, said exerting means comprising a set screw disposed within said last-mentioned socket, and an intermediate member disposed between the tip of said set screw and the body of a stud, said intermediate member having a larger surface area in contact with a stud than said set screw tip, and said intermediate member comprising a continuous portion of the sidewall of said socket, said portion upsettable into the threads of said stud to tightly hold said stud against rotation in the stud socket, and a waterproof sleeve member covering said terminal and sealingly mating with said housing to fully waterproof and enclose said connector.
