ABSTRACT:
A low profile strain relief cord grip is disclosed. The cord grip may be used in applications where a large number of conductors require their ganging in close proximity to one another in a panel or junction box. This cord grip provides strain relief on the cable, holding the cable from pulling out of the panel or from putting any strain on the terminal connections within. The cord grip is designed to be easily constructed and mass produced and does not require the use of complex dies as do some of the popular cord grips in common use in the industry today. The cord grip provides a liquid-tight seal, allowing its use indoors or outdoors. A wide range of cable sizes may be utilized with one size of cord grip. It utilizes a compressible one-piece grommet having an inner sleeve with lips in contact with the cable and an outer array of wedges that mate with a compression cone for compressing the grommet's periphery in an inward direction to tightly grip the cable in a water tight manner.
