Abstract
Abstract A device (1) comprising a flexible and resilient sleeve (2) made of rubber, rubber-like, plastics or similar material and a metal end termination (3) which has a screw thread connection with an electrical component (4) in the form of a multi-pin connector or plug. The end termination (3) has an interface (5) for conductors or wires of the multi-core cable and a body (6) which has a tapered entry (7) in which is received the sleeve (2) and metal braids (8) which screen the cable (9). There is a seal in the form of an O-ring (10) at the blind end of the entry (7) to prevent moisture getting into the cable. The other end of the sleeve (2) from the body (6) is mechanically secured as by adhesive to the other surface of an outer sheath of the multi-core cable (9) at anchor (11). To re-enter connection, the termination (3) and component (4) are unscrewed and pulled apart in direction (x) so that the convulsions of the sleeve (2) bunch up. An embodiment is described in which a metallic screen is independent of end termination (3) and is not retracted when the termination is retracted, the screen having a ring which has complementary mating engagement with the end termination.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
102 words
A device for terminating an electrical cable, comprising a flexible and resilient sleeve for securing to an outer surface of the cable, and an end termination engageable with and disengageable from an electrical component to which the cable is to be connected, the arrangement being such that when the end termination is disengaged from the component the device can be retracted effectively by shortening the sleeve and withdrawing the end termination whereby to expose the cable connection, and tooth means of a hollow body which forms the end termination for effecting a mechanical bond with a metallic screen which screens the cable.
Claim 2
Independent Claim
102 words
A device for terminating an electrical cable, comprising a flexible and resilient sleeve for securing to an outer surface of the cable, and an end termination engageable with and disengageable from an electrical component to which the cable is to be connected, the arrangement being such that when the end termination is disengaged from the component the device can be retracted effectively by shortening the sleeve and withdrawing the end termination whereby to expose the cable connection, and tooth means of a hollow body which forms the end termination for effecting a mechanical bond with a metallic screen which screens the cable.
Claim 3
Dependent Claim
24 words
A device according to claim 1, the end termination having a screw thread for engagement with a complementary screw thread of the electrical component.
Claim 4
Dependent Claim
10 words
A device according to claim 1, the sleeve being convoluted.
Claim 5
Dependent Claim
10 words
A device according to claim 3, the convolutions being helical.
Claim 6
Dependent Claim
24 words
A device according to claim 1, the end termination including a seal whereby the interior of the device is protected from penetration by moisture.
Claim 7
Dependent Claim
11 words
A device according to claim 5, the seal comprising an "O"-ring.
Claim 8
Independent Claim
134 words
A device for terminating an electrical cable, comprising a flexible and resilient sleeve for securing to an outer surface of the cable, and an end termination engageable with and disengageable from an electrical component to which the cable is to be connected, the arrangement being such that when the end termination is disengaged from the component the device can be retracted effectively by shortening the sleeve and withdrawing the end termination whereby to expose the cable connection, said device including a metallic screen secured at an end adjacent the end termination to a screen ring, the screen ring and end termination having complimentary mating surfaces whereby when the end termination and component are engaged the complementary mating surfaces are in engagement and when the end termination and component are separated the mating surfaces disengage.
Claim 9
Independent Claim
134 words
A device for terminating an electrical cable, comprising a flexible and resilient sleeve for securing to an outer surface of the cable, and an end termination engageable with and disengageable from an electrical component to which the cable is to be connected, the arrangement being such that when the end termination is disengaged from the component the device can be retracted effectively by shortening the sleeve and withdrawing the end termination whereby to expose the cable connection, said device including a metallic screen secured at an end adjacent the end termination to a screen ring, the screen ring and end termination having complimentary mating surfaces whereby when the end termination and component are engaged the complementary mating surfaces are in engagement and when the end termination and component are separated the mating surfaces disengage.
Claim 10
Dependent Claim
22 words
A device according to claim 7, wherein the complementary mating surfaces are respectively inclined surfaces of the end termination and screen ring.
Claim 11
Dependent Claim
11 words
An electrical cable according to claim 7, comprising a multi-core cable.
Claim 12
Dependent Claim
16 words
An electrical cable according to claim 8 connected to an electrical component comprising a multi-pin connector.
