Abstract
Abstract A metal clip is capable of securely engaging an electrical cable along the length thereof and is adapter for insertion and stable positioning within an elongated ventilation slot in the cabinet or chassis of an electronic apparatus to provide strain relief for the electrical cable. The strain relief clip may be in the form of either an appropriately twisted and bent metal wire or an appropriately configured solid metal clip formed by stamping. By providing a secure mounting for the electrical cable to the electronic device to which the cable is electrically coupled, movement between a connector located between the end of the cable and a receptacle mounted to, for example, a printed circuit board within the electronic device is prevented and electrical continuity is maintained.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
212 words
In an electronic apparatus having an electrical cable coupled thereto and at least one elongated, generally linear ventilation aperture therein, a strain relief clip for securing said electrical cable to said electronic apparatus and preventing relative motion therebetween, said strain relief clip comprising: a generally cylindrical, first portion open at both ends havinga slot extending the length thereof and adapted to receive the electrical cable along a portion of the length thereof in tight-fitting relation; an elongated, rigid, generally linear second portion adapted for insertion in said ventilation aperture along the length thereof and for engaging portions of said electronic apparatus immediately adjacent the lateral edges of said ventilation aperture when rotationally displaced after being inserted in said ventilation aperture so as to be aligned generally transverse to the length of said ventilation aperture; and an interconnecting portion coupling said first and second portions and positioned within and extending beyond said ventilation aperture, wherein the longitudinal axes of said first and second portions are in generally parallel alignment and said first clip portion is in spaced relation from said electronic apparatus to allow for the loose positioning of the strain relief clip within said ventilation aperture in facilitating the positioning upon and removal from the electronic apparatus of the strain relief clip.
Claim 2
Dependent Claim
212 words
In an electronic apparatus having an electrical cable coupled thereto and at least one elongated, generally linear ventilation aperture therein, a strain relief clip for securing said electrical cable to said electronic apparatus and preventing relative motion therebetween, said strain relief clip comprising: a generally cylindrical, first portion open at both ends havinga slot extending the length thereof and adapted to receive the electrical cable along a portion of the length thereof in tight-fitting relation; an elongated, rigid, generally linear second portion adapted for insertion in said ventilation aperture along the length thereof and for engaging portions of said electronic apparatus immediately adjacent the lateral edges of said ventilation aperture when rotationally displaced after being inserted in said ventilation aperture so as to be aligned generally transverse to the length of said ventilation aperture; and an interconnecting portion coupling said first and second portions and positioned within and extending beyond said ventilation aperture, wherein the longitudinal axes of said first and second portions are in generally parallel alignment and said first clip portion is in spaced relation from said electronic apparatus to allow for the loose positioning of the strain relief clip within said ventilation aperture in facilitating the positioning upon and removal from the electronic apparatus of the strain relief clip.
Claim 3
Dependent Claim
23 words
A strain relief clip as in claim 1 wherein said first, second and interconnecting portions thereof are comprised of a single metal wire.
Claim 4
Dependent Claim
25 words
A strain relief clip as in claim 1 wherein said first, second and interconnecting portions thereof are comprised of a single piece of sheet metal.
Claim 5
Dependent Claim
65 words
A strain relief clip as in claim 1 wherein the electronic apparatus further includes second and third apertures positioned on respective sides of said at least one ventilation aperture and said second portion of said strain relief clip further comprises first and second engaging means for insertion in an engagement with said second and third apertures, respectively, when said strain relief clip is rotationally displaced.
Claim 6
Dependent Claim
84 words
A strain relief clip as in claim 1 wherein the electronic apparatus further includes second and third generally linear apertures aligned with said at least one elongated, generally linear ventilation aperture and on opposite sides thereof in spaced relation therewith, said generally linear second portion of said strain relief clip further comprising engaging means on respective ends thereof for insertion in and engagement with a respective one of said second and third generally linear apertures when said strain relief clip is rotationally displaced 90°.
Claim 7
Dependent Claim
31 words
A strain relief clip as in claim 5 wherein each of said engaging means comprises a hook-shaped member for engaging a respective edge of said second and third generally linear apertures.
Claim 8
Dependent Claim
32 words
A strain relief clip as in claim 6 wherein said electronic apparatus includes a cabinet and said apertures comprise a plurality of parallel slots arranged in a side-by-side array in said cabinet.
Claim 9
Dependent Claim
32 words
A strain relief clip as in claim 6 wherein said electronic apparatus includes a chassis and said apertures comprise a plurality of parallel slots arranged in a side-by-side array in said chassis.
Claim 10
Dependent Claim
32 words
A strain relief clip as in claim 1 wherein said first cylindrical portion of said strain relief clip is resilient to facilitate the insertion therein and removal therefrom of the electrical cable.
