Abstract

A cable gland comprises has a body defining a passage, a sealing arrangement and a cable gripping member. The passage is configured to receive a cable having a surface. The sealing arrangement and the cable gripping member are locatable in the passage. The body has a sealing surface and a seal abutment surface adjacent the passage. The sealing arrangement has a seal, a seal deforming member and a link. The seal has an inner surface and an outer surface and defines an opening for receiving the cable and a further opening between the inner surface and the outer surface. The seal seals against the sealing surface as well as against the surface. The cable gripping member, the seal deforming member and the link form an electrically conductive train between a steel wire armour layer of the cable and a conductive part of the cable gland.

Claims (24)

1 . A cable gland comprising:

an elongate body defining an axially extending passage configured to receive a cable having an outer surface, the elongate body comprising an inner sealing surface and a seal abutment surface adjacent the passage, the seal abutment surface facing in a first direction; and

a cable gland sealing arrangement locatable in the passage, the cable gland sealing arrangement comprising:

an annular elastomeric seal comprising an inner sealing surface and an outer sealing surface and defining a first opening adjacent the inner sealing surface for receiving the cable and at least one further opening between the inner sealing surface and the outer sealing surface, in use, the inner sealing surface, seals against the outer surface of the cable, and the outer sealing surface seals against the inner sealing surface adjacent the passage;

an annular seal deforming member comprising a body having a first face which, in use, abuts the annular elastomeric seal, a second opposed face and an inner wall between the first face and the second opposed face, the inner wall defining a third opening for receiving the cable, and

at least one axially extending link which extends from a proximal end to a distal end, the distal end facing towards the seal abutment surface in a second direction opposite to the first direction, in use, the at least one axially extending link extends through the at least one further opening, the distal end abuts the seal abutment surface and the proximal end abuts the first face of the annular seal deforming member.

2 . The cable gland as claimed in claim 1 wherein the at least one axially extending link is integrally formed with any one of a) the first face of the annular seal deforming member; and b) the seal abutment surface.

3 . The cable gland as claimed in claim 1 wherein the body of the cable gland comprises a first body part and a second body part which are axially adjacent each other, the first and second body parts comprising respective mutually cooperating formations which, when actuated, cause the first and second body parts to be urged towards each other.

4 . The cable gland as claimed in claim 3 , wherein the first body part defines a first part of the axially extending passage which first part extends from a first end of the first body part to a second end of the first body part, wherein a first of the mutually cooperating formations is provided towards the second end of the first body part, and wherein the second body part comprises first and second concentric tubular parts, the second tubular part having a larger radius than the first tubular part, the first tubular part defining a second part of the axially extending passage which second part extends from a first end of the first tubular part to a second end of the first tubular part, the first end of the first tubular part providing the seal abutment surface and the second tubular part comprising a second of said mutually cooperating formations.

5 . The cable gland as claimed in claim 4 wherein the first tubular part is made of electrically conductive material.

6 . The cable gland as claimed in claim 1 wherein the annular elastomeric seal is circular in configuration and wherein the inner sealing surface and the outer sealing surface are concentric with each other about a center axis of the annular seal.

7 . The cable gland as claimed in claim 6 wherein the annular elastomeric seal comprises a first annular elastomeric seal part having an inner wall having an inner diameter and a concentric second annular elastomeric seal part having an outer wall having an outer diameter which is smaller than the inner diameter of the first annular elastomeric seal part, the first annular elastomeric seal part presenting the outer sealing surface of the annular elastomeric seal, the second annular elastomeric seal part presenting the inner sealing surface of the annular elastomeric seal and wherein the at least one further opening is ring-shaped and is defined between the inner wall of the first annular elastomeric seal part and the outer wall of the concentric second annular elastomeric seal part and wherein the at least one axially extending link is formed integrally with the first face and comprises a tubular stub extending through the at least one further ring-shaped further opening.

8 . The cable gland as claimed in claim 1 wherein the body of the annular seal deforming member is circular in configuration.

9 . The cable gland as claimed in claim 1 wherein the at least one further opening comprises a plurality of spaced sockets located on a first circle between the inner sealing surface and the outer sealing surface of the annular elastomeric seal, the first circle having a first radius and wherein the plurality of spaced sockets are equi-spaced from one another on the first circle by a first distance.

10 . The cable gland as claimed in claim 9 wherein the at least one axially extending link comprises a plurality of prongs which are integrally formed with the first face on a second circle having a second radius, the first circle and second circle are concentric and the first radius is equal to the second radius.

11 . The cable gland as claimed in claim 10 wherein each of the plurality of prongs is tapered in a direction from a respective proximal end immediately adjacent the first face towards a respective distal end of the prong and wherein the plurality of prongs are equi-spaced from one another by a second distance which is the same as the first distance.

12 . The cable gland as claimed in claim 9 wherein each of the plurality of spaced sockets is shaped similar to a prong.

13 . The cable gland as claimed in claim 1 further comprising a cable gripping member locatable in the axially extending passage, the cable gripping member comprising a body having a first end, a second end, an outer wall and an inner wall defining a passage for receiving the cable, the inner wall comprising formations for gripping the cable.

14 . The cable gland as claimed in claim 13 wherein the cable gripping member is tubular in configuration and defines an axial slot extending from the first end of the body of the cable gripping member to the second end of the body of the cable gripping member.

15 . The cable gland as claimed in claim 14 wherein the cable gripping member is resiliently constrictable.

16 . The cable gland as claimed in claim 13 wherein the outer wall of the cable gripping member slopes from the first end having a first outer diameter to the second end having a second outer diameter, which is larger than the first outer diameter.

17 . The cable gland as claimed in claim 13 wherein the inner wall of the cable gripping member slopes from the first end having a first inner diameter to the second end having a second inner diameter, which is smaller than the first inner diameter.

18 . The cable gland as claimed in claim 13 wherein the second face of the annular seal deforming member, in use, abuts the second end of the cable gripping member.

19 . The cable gland as claimed in claim 13 wherein at least one of the cable gripping member, the annular seal deforming member and the at least one axially extending link are made of electrically conductive material.
