Abstract
A cable gland has a body for receiving part of a cable extending through the cable gland, wherein the body comprises an entry item and a second body part adapted to be mounted to the entry item A barrier tube is at least partly located within the body and a seal sealingly engages the cable and the barrier tube to prevent loss of pressure and/or transmission of flame past the seal and to define a space for receiving curable liquid material and substantially prevent the curable liquid material from bonding to an internal surface of the entry item.
Claims23
A cable gland comprising:
- a body for receiving part of a cable extending through the cable gland, wherein the body comprises a first body part and a second body part adapted to be mounted to the first body part;
- a barrier device adapted to be at least partly located within the first body part;
- a first sealing device adapted to sealingly engage the cable and the barrier device, wherein the barrier device and said first sealing device define a space for receiving curable liquid material such that the barrier device substantially prevents said curable liquid material from bonding to an internal surface of the first body part;
- and
- a seal support device adapted to engage the first sealing device and to resist pressure applied to said first sealing device from said space, wherein the seal support device defines an aperture for enabling engagement of the cable with the first sealing device from a side of the first sealing device opposite to the space.
A seal support for supporting a seal in a cable gland, the seal support defining an aperture for receiving part of a cable extending through the cable gland and comprising:
- a base portion adapted to be mounted to a body of the cable gland;
- and
- a tapering portion comprising a plurality of support members pivotably mounted to the base portion and adapted to engage the cable and support a seal engaging the cable, wherein at least one said support member has a respective engaging surface for engaging a further said support member adjacent thereto as a result of pivoting of the support members relative to the base portion towards a longitudinal axis of said tapering portion, such that said support member and said further support member engage each other and slide relative to each other.
A cable gland comprising:
- a body for receiving part of a cable extending through the cable gland, the body comprising a first body part and a second body part adapted to be mounted to the first body part;
- a clamping device means comprising an inner clamping part and an outer clamping part for clamping an armour layer of a cable therebetween, and
- a retaining device for releasably retaining the outer clamping part in the second body part, wherein the retaining device is adapted to resiliently engage an internal surface of the second body part and to resiliently deform as a result of insertion of the outer clamping part into the second body part to enable the outer clamping part to be releasably mounted to the retaining device and be releasably retained in the second body part.
