Abstract
Abstract A slip-fit electrical connector for a threaded transformer stud has a stepped or key type stud hole which includes an oversize unthreaded circular hole on top and a slightly smaller intersecting hole on the bottom. The bottom hole has threads matching those of the stud and a jam screw forces the threaded stud into intimate contact with the threads of the smaller hole, such contact extending over a substantial arc. The connection provides a tight and improved electrical connection having simplicity of installation.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
162 words
A slip-fit transformer stud connector comprising an elongated body of conductive material, a plurality of conductor wire pads extending transversely of said body, means operative to clamp conductors to said pads, a stud hole in the end of said body operative to receive said transformer stud in a slip-fit, said hole being formed with two vertically spaced centers forming two-hole portions, the hole portion on the top center being a larger diameter than the hole portion on the bottom center with the hole portion on the bottom center intersecting the hole portion on the top center, the bottom hole portion being the same diameter as said stud, jam screw means above said stud hole operative to force the transformer stud against the hole portion on the bottom center locking the connector against rotation on the stud and providing a low resistance electrical connection between the stud and body, said transformer stud being threaded, and said somewhat smaller bottom portion including matching threads.
Claim 2
Dependent Claim
162 words
A slip-fit transformer stud connector comprising an elongated body of conductive material, a plurality of conductor wire pads extending transversely of said body, means operative to clamp conductors to said pads, a stud hole in the end of said body operative to receive said transformer stud in a slip-fit, said hole being formed with two vertically spaced centers forming two-hole portions, the hole portion on the top center being a larger diameter than the hole portion on the bottom center with the hole portion on the bottom center intersecting the hole portion on the top center, the bottom hole portion being the same diameter as said stud, jam screw means above said stud hole operative to force the transformer stud against the hole portion on the bottom center locking the connector against rotation on the stud and providing a low resistance electrical connection between the stud and body, said transformer stud being threaded, and said somewhat smaller bottom portion including matching threads.
Claim 3
Dependent Claim
24 words
A connector as set forth in claim 1 wherein said pads are formed by wire ports, and set screw means to clamp conductors therein.
Claim 4
Dependent Claim
23 words
A connector as set forth in claim 1 wherein said jam screw forces the matching threads into intimate contact over a substantial arc.
Claim 5
Dependent Claim
20 words
A connector as set forth in claim 3 wherein said substantial arc is from about 135 to about 175 degrees.
Claim 6
Dependent Claim
105 words
A slip-fit transformer stud connector comprising an elongated body of conductive material, a plurality of conductor wire pads extending transversely of said body, means operative to clamp conductors to said pads, a stud hole in the end of said body operative to receive a transformer stud in a slip-fit, said stud hole having the transverse shape of a keyhole and having a somewhat smaller bottom portion, jam screw means to force the stud into the somewhat smaller bottom portion to lock the connector against rotation about the axis of the stud, said transformer stud being threaded and said somewhat smaller bottom portion including matching threads.
Claim 7
Dependent Claim
105 words
A slip-fit transformer stud connector comprising an elongated body of conductive material, a plurality of conductor wire pads extending transversely of said body, means operative to clamp conductors to said pads, a stud hole in the end of said body operative to receive a transformer stud in a slip-fit, said stud hole having the transverse shape of a keyhole and having a somewhat smaller bottom portion, jam screw means to force the stud into the somewhat smaller bottom portion to lock the connector against rotation about the axis of the stud, said transformer stud being threaded and said somewhat smaller bottom portion including matching threads.
Claim 8
Dependent Claim
30 words
A transformer stud connector as set forth in claim 5 wherein said stud hole includes a larger circular unthreaded portion and a circular smaller bottom portion intersecting the larger portion.
Claim 9
Dependent Claim
23 words
A connector as set forth in claim 5 wherein said jam screw forces the matching threads into intimate contact over a substantial arc.
Claim 10
Dependent Claim
27 words
A connector as set forth in claim 5 wherein said pads are formed by wire ports, and set screws extending into said ports to clamp conductors therein.
Claim 11
Dependent Claim
20 words
A connector as set forth in claim 5 wherein said substantial arc is from about 135 to about 175 degrees.
