Abstract : The rapid growth of buried service wire use in the telecommunications industry has increased the demand for a reliable, low cost means for splicing new or damaged buried service wire. Splicing kits of various types for this purpose have been available for several years. Each type has been subject to varying degrees of craftsperson sensitivity at installation and reliable long term performance of the shield interface. For the most part, until recently the shield bonding devices consisted of either a split bolt and nut arrangement or a screw secured clamping arrangement. Neither of these devices provided a satisfactory follow-up feature to compensate for long term creep of the plastic components within the cable. This paper describes a unique stored energy clamping device which provides long term creep compensation. The device consists of two identical U-shaped spring steel pieces which fit and latch together hermaphroditically to apply and maintain spring force at four points for large area shield to shield interface. This shield bonding device is easily manufactured at low cost, can be installed without tools is independent of craftsperson sensitivity, and will accommodate the range of wire sizes most commonly used.
