Abstract
A new device and method for providing strain relief to a cable including a base with a tubular extension, the tubular extension having a plurality of deflectable arms, each of which are radially converged and constricted about a cable under a compression force caused by the tightening of a nut having a tapered region formed in an inner nut channel.
Claims11
A device for providing strain relief to cables of varying diameters, comprising:
- a base;
- a tubular extension extending longitudinally from a first end of said base, said tubular extension comprising a plurality of arms inwardly deflectable under a compression force, each of said arms having a taper of decreasing width from said first end of said base to an opposite end of said arms;
- and
- a nut having an inner channel, said nut having a first end and a second end, said inner channel having a tapered region formed such that mounting sail nut over said tubular extension forces said plurality of arms to constrict around a cable insertable within said tubular extension.
1 more element
A junction box, comprising:
- a wall having an aperture;
- a strain relief device mounted to said wall and positioned in overlying relationship to said aperture of said wall, said strain relief device having a base, a tubular extension extending longitudinally from a first end of said base, said tubular extension comprising a plurality of arms, each of said arms having a taper of decreasing width from said first end of said base to an opposite end of said arms, and a nut having an inner channel, said inner channel having a tapered region formed such that mounting said nut over said tabular extension forces said plurality of arms to constrict around a cable insertable within said tubular extension.
A method for grippingly securing a cable, comprising the steps of:
- inserting a cable into a tubular portion of a body o f a strain relief device, said tubular portion having a plurality of deflectable arms compressible by a nut mountable over said tubular portion, said arms each having a taper of decreasing width from a base of said arms to an end of said arms, and said nut having an inner channel with a tapered region;
- and
- tightening said nut over said tubular portion, such that said deflectable arms are deflected radially inward to grippingly secure said cable.
