ABSTRACT:
A contraction termination device and method for electrical conductor cable or the like encased in a sheathed braided material. The device employs an elongated sleeve having opposed lead and terminal ends with an internal passageway communicating therebetween. The sleeve tapers outwardly from the lead end along a tapered area which merges into a roughened area which then merges into an intermediate area. These three areas are all coated for creating a friction surface along the sleeve. The internal cable conductors or strands are passed through the sleeve passageway from the lead end and the braided sheath is passed over the sleeve lead end to the intermediate area. Thereafter, the sheath is affixed to the sleeve at the intermediate area by tie wraps and the ends of the conductors or strands may be conveniently interconnected to attendant equipment at the sleeve terminal end. A protective covering is received over the sleeve in preferably a close embracing relationship therewith and may comprise a heat shrinkable tube. A separate protective housing may also be received over the sleeve with the housing including means for supporting and gripping the cable outwardly from the sleeve lead end to provide cable bending strain relief and to maintain the integrity of the cable termination.
