Abstract

An electrical connector has a conductive member formed from several sheets of a resilient conductive material, such as a wire mesh or conductive textile. The sheets are layered and joined together at intervals to form separate passages between the sheets through the member. Screened wires in the connector pass through respective passages and the member is compressed about the wires by a strap tightened about the member so that electrical connection is made to the wire screens. The resilience of the member means that the strap can be released and retightened, allowing removal and replacement of wires.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 is a perspective, exploded view of the connector;

FIG. 2 is a perspective view of a part of the wire mesh member of the connector, illustrating its construction;

FIG. 3 shows schematically an alternative wire mesh member made from a single strip of wire mesh;

FIG. 4 shows another alternative wire mesh member formed in a spiral; and

FIG. 5 is an exploded perspective view of a modified form of connector.

Claims

1. An electrical connection comprising: a member formed substantially entirely of a conductive, resilient sheet material, said member having a plurality of passages extending through said member between opposite ends, one for each of a plurality of wires; and a clamp for radially inwardly compressing said member about said wires such that said member makes effective electrical connection with an outside of each wire when said clamp is tightened and such that said member recovers substantially its original shape when said clamp is released.

2. A connection according to claim 1, wherein said sheet material is of a wire mesh.

3. A connection according to claim 1, herein said member is of a conductive woven or knitted material.

4. A connection according to claim 1, wherein said member comprises a combination of metal fibres and non-metal fibres.

5. A connection according to claim 1, wherein said member includes two sheets of textile separated from one another by spacer fibres.

6. A connection according to claim 1, wherein said member is of beryllium copper, copper or Monel.

7. A connection according to claim 1, wherein said clamp includes a strap embracing said member.

8. A connection according to claim 1 including a disc located adjacent said member, and wherein said disc has an aperture for each said wire.

9. A connection according to claim 1, wherein said sheet material has a plurality of layers joined with one another at locations to form passages between the layers between the locations.

10. A connection according to claim 1, wherein said member includes a continuous strip of material folded backwards and forwards.

11. A connection according to claim 1, wherein said member is of ladder shape rolled into a spiral.

12. A connection according to claim 1, wherein said member includes a sealing material, and wherein said sealing material is displaceable by insert on of wires in said member to enable electrical contact between the wires and said member.

13. A connection according to claim 9, wherein said sealing material is a gel.

14. A connection according to claim 9, wherein said sealing material is a settable material.
