Abstract
Abstract The invention disclosed herein is directed to a terminal connector for use in connecting a plurality of terminal lugs to a transformer current feedline. The terminal connector includes a threaded end which receives an adaptor having both right and left-hand threads formed thereon. The adaptor engages the threaded end of the terminal connector and the threaded end of a transformer current feedline. Upon turning the adaptor in one direction, the terminal connector and the feedline are brought tightly together for firm mechanical and electrical connection. When turning the adaptor in the other direction, the terminal connector and the transformer current feedline are separated to facilitate changing the transformer without necessitating the removal of the plurality of terminal lugs fastened to the terminal connector. Insulated shields are formed on the adaptor, the shields including radially outwardly extending and axially extending hood portions which overlie all metal conductive surfaces to prevent inadvertent electrical shock to personnel connecting and disconnecting the terminal connector.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
196 words
A terminal connector for current distribution, comprising in combination: an elongated conductive body having threaded socket means formed at one end thereof, a plurality of lug receiving means formed at spaced locations on said elongated conductive body for receiving cable lugs to be connected thereto, threaded connector means of conductive material connecting a current feedline to said threaded means formed at one end of said elongated conductive body, said threaded conductor means having a threaded stud extending therefrom, and an insulated shield covering the outer peripheral surface of said threaded connector means and having a first hood portion annularly about said threaded stud means and spaced therefrom, and extending axially therefrom and overlapping with said elongated conductive body as said threaded stud mates with said socket, and a second hood portion positioned annularly about said current feedline, and extending therefrom, so that when said current feedline is connected with said threaded connector means said second hood portion overlaps said threaded connector means said first and second hood portions extends axially to protrude beyond both ends of said threaded connector means so as to prevent inadvertent electrical shock to personnel connecting and disconnecting said threaded connector means.
Claim 2
Dependent Claim
196 words
A terminal connector for current distribution, comprising in combination: an elongated conductive body having threaded socket means formed at one end thereof, a plurality of lug receiving means formed at spaced locations on said elongated conductive body for receiving cable lugs to be connected thereto, threaded connector means of conductive material connecting a current feedline to said threaded means formed at one end of said elongated conductive body, said threaded conductor means having a threaded stud extending therefrom, and an insulated shield covering the outer peripheral surface of said threaded connector means and having a first hood portion annularly about said threaded stud means and spaced therefrom, and extending axially therefrom and overlapping with said elongated conductive body as said threaded stud mates with said socket, and a second hood portion positioned annularly about said current feedline, and extending therefrom, so that when said current feedline is connected with said threaded connector means said second hood portion overlaps said threaded connector means said first and second hood portions extends axially to protrude beyond both ends of said threaded connector means so as to prevent inadvertent electrical shock to personnel connecting and disconnecting said threaded connector means.
Claim 3
Dependent Claim
121 words
The terminal connector according to claim 1 wherein said threaded connector means includes a threaded adaptor having first and second threaded portions, said first threaded portion engaging said thread means of said elongated conductive body and said second threaded portion receiving the current feedline means from which current is delivered to said lug receiving means, said threaded adaptor having first and second threaded portions arranged simultaneously to tighten against said elongated conductive body and said current feedline means upon turning the adaptor in one direction and simultaneously to loosen said elongated conductive body and said current feedline upon turning said adaptor in another direction, whereby said current feedline can be changed without removing the cable lugs from said lug receiving means.
Claim 4
Dependent Claim
47 words
The terminal connector according to claim 2 further including a jam nut interposed between said threaded adaptor and a current feedline insulating member to cause said threaded adaptor to be securely locked in tight physical and electrical connection with said thread means of said elongated conductive body.
Claim 5
Dependent Claim
90 words
The terminal connector according to claim 3 wherein said threaded adaptor has a hood portion of insulating material extending radially outwardly and axially therefrom to overlie a corresponding peripheral portion of said thread means of said elongated conductive body to provide electrical insulation from conductive surface parts thereof, and said jam nut includes hood portions extending in opposite directions to circumscribe and overlie said threaded adaptor and said insulator completely to conceal all metal conductive components so that inadvertent electrical shock to personnel connecting and disconnecting the same is eliminated.
