Twin electrical lead and connector assembly

Abstract

A length of leg wire comprising a pair of electrical leads is coiled into a conical helix. An electrical connector is attached at one or both ends. The electrical connector is characterized as capable of maintaining the ends of the two electrical leads in non-conductive and preferably also water-resistant condition. The connector further may also be characterized as permitting a water-resistant, high tensile strength splicing of the ends of the leg wire with another pair of similar electrical leads without the use of splicing tools. The other end of the leg wire may be clean cut or connected to another electrical connector. The coiled portion is flexible but shape sustaining and therefore collapses and expands in the coiled arrangement. The assembly is packaged in the collapsed configuration. When removed from the package, the coiled portion of the leg wire expands but retains the coiled configuration. The coiled leg wire is much easier to work with in the field as the coil expands and retracts readily without tangling. Moreover, the coil configuration allows the wire to rest on its side in the expanded form so that it can be fed down the blast hole easily without the wire becoming tangled. Further, the coiled portion can be retrieved quickly by simply regathering the coiled portion with one hand.
