  • Patent number: 4193657
    Abstract: A multiple projecting contact pot head termination that is formed on an end portion of an armored cable that maintains the electrical conductors in the termination in fixed insulated positions relative to one another, and with the assurance that they will not short out under adverse conditions such as when the termination is removably connected to an electric motor that actuates a down hole pump in an oil well. In forming the termination, a substantial length of the armor is separated from an end portion of the cable and internal insulation removed from the cable to expose the insulated conductors. Each conductor has the end portion of insulation removed therefrom, and the bared end portion subsequently soldered to a tubular externally threaded copper connector. Each connector threadedly engages an elongate copper terminal, and in association with first and second tubular sleeves is held in a fixed longitudinal position within a retainer of fiberglass or the like.
