Glands for terminating cables and pipes

摘要

An insulation piercing earthing ring for a gland termination to provide earth continuity between an electrically conductive gland body and an electrically conductive inner sleeve of an insulated cable or pipe has a flat annular washer for locating against the end of the cable or pipe with at least one contact finger extending from the periphery of the washer to surround the cable or pipe and terminating in an inwardly directed projection for piercing the insulation. The contact finger extends axially and radially outwards from the periphery of the washer in the undeformed free state and is deformed radially inwards by engagement with a tapered entry portion of the gland body causing the projection to pierce the insulation and contact the electrically conductive inner sleeve.
