Abstract
Abstract The invention provides an L-shaped connector for connecting a high voltage electric cable to a bushing of a transformer, switchgear, or other electrical apparatus. A first arm of the connector is tapered to be a push-fit on to the bushing, and the other arm has a heat-shrinkable tubing integral therewith for receiving, and sealing on to, a stripped cable. Electrical connection to the cable is made completely within the insulating body of the connector, by a screw-threaded pin that is accessed through the first arm of the connector.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
121 words
A connector arranged to connect a high voltage electric cable to electrial apparatus, the connector comprising an electrically insulating body having a first socket arranged to receive an electrical terminal of the apparatus, and a second socket arranged to receive a stripped end of the cable and comprising a non-recoverable portion which is integral with the first socket and a recoverable tubular end portion which is molded at one end thereof into the non-recoverable portion; and electrically conductive means arranged to provide a conductive path between the first and second sockets thereby, in use, to provide electrical interconnection between the cable and the terminal of the apparatus, the electrically conductive means being contained wholly within the insulating body of the connector.
Claim 2
Dependent Claim
121 words
A connector arranged to connect a high voltage electric cable to electrial apparatus, the connector comprising an electrically insulating body having a first socket arranged to receive an electrical terminal of the apparatus, and a second socket arranged to receive a stripped end of the cable and comprising a non-recoverable portion which is integral with the first socket and a recoverable tubular end portion which is molded at one end thereof into the non-recoverable portion; and electrically conductive means arranged to provide a conductive path between the first and second sockets thereby, in use, to provide electrical interconnection between the cable and the terminal of the apparatus, the electrically conductive means being contained wholly within the insulating body of the connector.
Claim 3
Dependent Claim
127 words
A connector arranged to connect a high voltage electric cable to electrical apparatus, the connector comprising an electrically insulating body having a first socket arranged to receive an electrical terminal of the apparatus, and a second socket arranged to receive a stripped end of the cable and comprising a non-recoverable portion and a recoverable tubular end portion, one end of which is recovered onto a tubular support member, said one end and said support member being molded into the non-recoverable portion; and electrically conductive means arranged to provide a conductive path between the first and second sockets thereby, in use, to provide electrical interconnection between the cable and the terminal of the apparatus, the electrically conductive means being contained wholly within the insulating body of the connector.
Claim 4
Dependent Claim
127 words
A connector arranged to connect a high voltage electric cable to electrical apparatus, the connector comprising an electrically insulating body having a first socket arranged to receive an electrical terminal of the apparatus, and a second socket arranged to receive a stripped end of the cable and comprising a non-recoverable portion and a recoverable tubular end portion, one end of which is recovered onto a tubular support member, said one end and said support member being molded into the non-recoverable portion; and electrically conductive means arranged to provide a conductive path between the first and second sockets thereby, in use, to provide electrical interconnection between the cable and the terminal of the apparatus, the electrically conductive means being contained wholly within the insulating body of the connector.
Claim 5
Dependent Claim
50 words
A connector according to claim 1 or 2, wherein the electrically conductive means comprises a screw-threaded pin member that is co-operable with an internally-threaded portion of the connector so as to be introduced through said first socket and to provide, in use, electrical contact with the conductor of the cable.
Claim 6
Dependent Claim
36 words
A connector according to claim 3, wherein the internally-threaded portion of the connector comprises an electrically conductive portion that is disposed in the second socket and that is arranged to receive the end of the cable.
Claim 7
Dependent Claim
53 words
A connector according to claim 1 or 2, wherein the electrically conductive means comprises a pin member, integral with the insulating body of the connector, that is electrically connected to means for retaining within the connector the end of a cable that is introduced, in use, into the second socket of the connector.
Claim 8
Dependent Claim
29 words
A connector according to claim 1 or 2, comprising a further socket suitable for providing access to the electric cable that is introduced, in use, into the second socket.
Claim 9
Dependent Claim
16 words
A connector according to claim 1 or 2, comprising an air-bleed passageway between the sockets thereof.
Claim 10
Dependent Claim
31 words
A connector according to claim 1 or 2, wherein the second socket is defined by a wall of soft material such that, in use, the cable is a tight push-fit thereinto.
Claim 11
Dependent Claim
31 words
A connector according to claim 1 or 2, wherein the inner wall of the second socket is arranged such that the connector can accommodate a cable of more than one size.
Claim 12
Dependent Claim
40 words
A connector according to claim 1 or 2, comprising at least one insert that is arranged to be mounted in the second socket, such that the connector is suitable for receiving, in use, a cable of more than one size.
