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.
Claims9
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.
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.
