Abstract

A termination device utilizes a frusto-conical wedge positioned on the cable for forming a protuberance thereon at the area of termination. A first set of helical elements having a helical lay of one hand is disposed in a surrounding relationship with at least an axial portion of the cable with the cable and first set of helical elements being received through a longitudinal bore extending between the opposed wedge ends. A second set of helical elements having a helical lay of the opposite hand closely encircle the wedge outer surface at least between the opposed wedge ends and also encircle at least a portion of the first set of helical elements extending outwardly from the wedge bore at the smaller diameter wedge lead end. For conventional electrical conductor cable or the like, the first and second sets of elements are comprised of preformed helical rods having predetermined internal diameters and pitch lengths. For conventional armored cable, the first set of elements comprises the inner layer of armor strands and the second set of elements comprises the outer layer of armor strands. The wedge, along with the associated portions of the cable and first and second sets, is received within a housing. A retainer member continuously urges and pre-loads the wedge into a housing frusto-conical passageway, the passageway being conveniently defined by a subhousing receivable in the housing to facilitate assembly of the termination device in the field externally of the housing.
