Abstract
Abstract A battery cable for use in severe electrochemical environments comprising a plurality of copper conductors clad with nickel and coated with insulation material, a nickel braid encompassing the insulated conductors, an encapsulant generally permeating and surrounding the nickel braid and the insulated conductors, nickel lugs welded to the conductors at one of the ends of the cable, and a molded connector portion at the other end of the cable. The nickel braid is twisted at its end and is welded to a lug to form a ground connector.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
131 words
A cable for use in electrochemical environments comprising an electrical conductor including a plurality of copper strands of from about 0.005 inch to about 0.009 inch diameter and having a from about 0.0003 to about 0.0007 inch nickel cladding enclosing and integral with each strand, a layer of insulation enclosing each said nickel clad copper strand, said insulation selected from the group consisting of polytetrafluoroethylene, a copolymer of fluorinated ethylene and propylene, polychlorotrifluoroethylene, polyvinylidene fluoride, polyvinylchloride, polyethylene, and irradiated polyethylene; a nickel braid shield of from about 0.004 inch to about 0.006 inch diameter and about 100 percent nickel wire generally encompassing said conductors; and encapsulating materiAl selected from the group consisting of polyether-type polyurethane resin and flexibilized epoxy resin encapsulating said one or more insulated conductors and said nickel braid.
Claim 2
Dependent Claim
131 words
A cable for use in electrochemical environments comprising an electrical conductor including a plurality of copper strands of from about 0.005 inch to about 0.009 inch diameter and having a from about 0.0003 to about 0.0007 inch nickel cladding enclosing and integral with each strand, a layer of insulation enclosing each said nickel clad copper strand, said insulation selected from the group consisting of polytetrafluoroethylene, a copolymer of fluorinated ethylene and propylene, polychlorotrifluoroethylene, polyvinylidene fluoride, polyvinylchloride, polyethylene, and irradiated polyethylene; a nickel braid shield of from about 0.004 inch to about 0.006 inch diameter and about 100 percent nickel wire generally encompassing said conductors; and encapsulating materiAl selected from the group consisting of polyether-type polyurethane resin and flexibilized epoxy resin encapsulating said one or more insulated conductors and said nickel braid.
Claim 3
Dependent Claim
15 words
The cable of claim 1 wherein said nickel braid density is at least 90 percent.
Claim 4
Dependent Claim
106 words
The cable of claim 1 wherein nickel lugs are welded at an end of said insulated conductors at one end of said cable, solder pots are connected to another end of said conductor at another end of said cable, said braid wire is welded to one of said nickel lugs at said one end of said cable to serve as electrical ground, a generally annular brass shield is connected at said other end of said cable to said nickel braid shield, an adapter is connected to said generally annular brass shield, and said encapsulating material partially encapsulates said adapter, said brass shield, and said solder pots.
Claim 5
Dependent Claim
49 words
The cable of claim 3 wherein said conductors project through a wall of said nickel braid shield at said one end of said cable and said encapsulating material encapsulates said conductor projection and terminates at a location adjacent and beyond said conductor projection through said nickel braid shield wall.
