The following specification describes a cable terminal assembly incorporating a conductive metal plate secured to a variable size multi strand cable by casting or molding a mass of conductive casting material around the plate and cable to form a mechanical junction as well as an electrical connection therebetween. The plate and conductive casting material are covered by an insulating jacket. Aligned passages are provided in the jacket above and below the plate in alignment with an aperture in the plate to permit the plate to be electrically secured to battery terminals employing studs for fastening. The passage in the insulating jacket above the plate is defined by a ring having an outer diameter sized for nesting within the jacket passage below the plate of a second cable terminal assembly, so that two or more cable terminal assemblies may be stacked on a single battery terminal stud at a desired angular orientation. The ring formed on the insulated jacket, whether mounted on a battery terminal stud singly or in stacked multiples, provides a moisture seal at the terminal to impede or prevent corrosion, normally a serious problem with battery cable systems. Stacking two of the cable terminal assemblies on a battery terminal stud with a conductive spacer in the jacket ring of the lowermost cable terminal assembly provides an electrical connection between the plates of the two stacked cable terminal assemblies and permits a plurality of connections to be established at each battery terminal. The conductive spacer can be a separate ring shape, or can be permanently attached to the lowermost terminal plate, or the plate can be formed to provide a functional spacer. The foregoing cable terminal assembly simplifies the cabling and connections required for connecting a plurality of engine starting batteries in common, and impedes or prevents corrosion at the terminals.
A cable terminal assembly for use in establishing a connection between a conductor cable and a battery terminal of the type comprising a metal base and a threaded stud projecting upwardly from the base, the improvement comprising, in combination, a conductive metal terminal plate arranged so that one end thereof underlies an exposed end of said conductor, an aperture formed in the opposite end of said terminal plate to receive said stud member, connecting means connecting said conductor and terminal plate to form both a mechanical and electrical connection therebetween, an insulator jacket substantially covering said connecting means and said terminal plate, said insulator jacket having openings formed therein above and below said aperture in said plate, said openings being larger than said plate aperture to expose a portion of said plate surrounding said aperture, and a raised wall member formed integral with said jacket and surrounding the opening above said plate aperture, said opening below said plate aperture being dimensioned to receive said wall member to permit a plurality of said cable assemblies to be stacked one above the other in closely interfitted relation.
