Support and strain relief combination

Claim 1

A support and strain relief comprising the combination of a support having an opening and a strain relief to be engaged in the opening of the support, said strain relief being formed of a resiliently deformable material and including a first portion and an integral second portion, said first portion having a web with elongated linear ribs spaced apart in the direction of intended application to a multi-core cable or a plurality of wires disposed side by side, said web and said ribs defining collectively a trough, said second portion having a base elongated in the direction of intended application of the multi-core cable or the plurality of wires disposed side by side and a linear transverse wall upstanding intermediate the ends of the base, whereby a multi-core cable or a plurality of wires disposed side by side when placed between the first portion and the second portion and when abutted under pressure by said web and said ribs and said wall, will be forced into a U-shaped bend and will be tightly held by friction against movement relative to the strain relief, at least one of said first and second portions including lug means extending from a lateral edge thereof for abutment, when in use, against a surface of said support adjacent said opening in which the strain relief is to be engaged, and said support having two separate mating parts which, when assembled, define said opening to receive said strain relief, at least one of said mating parts including said surface for abutment by said lug means on the strain relief to resist the strain relief being separated from the support, and wherein said support has keying ribs and one of said first and second portions has cooperating keying ribs presented at its exterior for engagement with said keying ribs of said support in which the strain relief is to be positioned, thereby to key the strain relief against being pulled out of the support.
