Abstract:
An assembly for releasably connecting a wire comprising:a. a protective block having a plurality of spaced, cylindrically shaped pins;b. a metal IDC contact having(i) a first end having a hollow cylindrically shaped portion to engage one of said cylindrically shaped pins on said protective block to retain said IDC contact relative to said block,(ii) a second end defining a bifurcated end having(a) inwardly facing opposed surfaces having parallel opposed surfaces spaced relative to one another to make contact with a wire located between said inwardly facing opposed surfaces, and angularly spaced opposed surfaces diverging away from said parallel surfaces,(b) a curved surface opposite said angularly spaced opposed surfaces and contacting said parallel surfaces to define a terminal portion of said bifurcated end,(c) parallel outwardly facing opposed surfaces,(d) flat side surfaces parallel to one another, and(e) end surfaces opposite said terminal portion to define an opening within said bifurcated end to receive said wire, and(iii) a flexible tab on each of said parallel outwardly facing opposed surfaces defined in part by said flat side surfaces, said tabs extending outwardly a distance away from said parallel outwardly facing surfaces;c. a box shaped relief cap having(i) surfaces defining a cavity to receive said bifurcated end, said defining surfaces of said cavity including(a) parallel inwardly facing opposed surfaces spaced apart a distance slightly greater than the parallel outwardly facing opposed surfaces of said bifurcated end and less than the distance the outwardly extending portions of said tabs to flex said tabs towards said outwardly facing surfaces when said bifurcated end is moved within said cavity,(b) flat side surfaces parallel to one another and spaced apart a distance slightly greater than said flat side surfaces of said bifurcated end, and(c) an end surface enclosing said cavity at one end within said cap;(ii) a curved surface at the open end of said cavity shaped to engage a wire and parallel to said parallel inwardly facing opposed surfaces defining said cavity; and(iii) locking windows opening into said parallel inwardly facing opposed surfaces defining said cavity and the exterior of said strain relief cap, said windows being in alignment with said flexible tabs when said bifurcated end is located within said cavity of said strain relief cap and a wire is located between said inwardly facing parallel opposed surfaces of said bifurcated end and in contact with said curved surface of said cap and said curved surface of said bifurcated end whereby said tabs flex outwardly into said locking windows to retain said bifurcated end relative to said strain relief cap; andd. a tool having(i) a pair of movable spaced arms that may be located juxtaposition to said locking windows, and(ii) a pair of tangs secured to and movable with said arms and each shaped for insertion into one of said locking windows for engagement with said flexible tab in said locking window, whereby said tabs may be moved with said arms into said windows to depress said tabs out of said windows and grip said relief cap for removal of said relief cap from said second end.
