CABLE GLANDS

摘要

A cable gland for use with cables (1) having armour (3) of widely differing thickness comprises a body (5) and a gland nut (7) threaded to the body (5) which together enclose an armour grip (9) comprising an armour cone (10) having a male frustoconical surface co-operating with a female frustoconical surface on an armour ring (11). The frustoconical surfaces have substantially equal semiangles in the range 12-20 DEG and the armour ring (11) and the armour cone (10) are urged together by a mechanism independent of and contained within the gland nut (7). The larger-than-normal semiangle allows the whole range of armour thicknesses to be accommodated by the same gripping components without requiring undue length, and the separated mechanism overcomes side effect that the cone grip is not self-locking. Preferred mechanisms also improve perfomance in deluge tests.
