Abstract
Abstract A bonding kit assembly and assembly and method for use in bonding together the shields of spliced cables interiorly of a shielded splice housing with a bonding connection to the splice casing. The bonding unit per se comprises a pair of shoes insertable lengthwise of each cable end and between the leading ends of which wide areas of the cable shield and sheath are compressively sandwiched as the leading ends of the shoes are pivoted thereagainst by clamping means and cooperating fulcrum means between the trailing ends of said shoes. The fulcrum means includes either a single or a pair of broad edged tangs crosswise of the shoes and supplementing the shoe clamping bolt in providing a low resistance high density current path between the two shoes. The leading ends of the bonding shoes extend beneath gasketing at the cable entrances to the splice housing and are interconnected at the opposite ends of the cable splice by heavy duty conductive strapping and solderless connectors, the bonding strap including a branch bonded to the splice casing. The heavy duty strapping transfers cable tensile stresses across the splice connections without reliance on the splice casing for this purpose. The latter may be opened for servicing without disturbing or interfering with the integrity of the installed bond assembly or risk of placing any splice connection under tensile stress. The splice casing is usable with a wide range of cable sizes without need for adapters and provides a grounded shield for the spliced conductors which overlaps the cable shield at each end of the splice.
