Abstract
Re-enterable service wire splice closure having a shallow cup containing a sealant into which is placed an inverted cylindrical shallow tray containing the spliced ends of the service wire, the cup and the tray have aligned slots through which the cable may extend and a screw cap drives the tray into the cup forcing the sealant around the wire splice connectors to encapsulate the same for moisture resistance. A connector element in the tray serves as the strain relief element for the service wire and as the connector element for the grounding shield.
Claims14
A re-enterable moisture-resistant closure for conductor splices between preconnected wires of a cable, said closure comprising
- a shallow cup having a bottom wall and a cylindrical side wall formed with threads adjacent the open end of the cup and said side wall having a plurality of wire-receiving slots extending from the open end of the cup toward the bottom wall,
- a sealant substantially filling said cup,
- a tray having a size to receive the conductor splices and having a size to fit within said cup, said tray having side walls having a plurality of wire-receiving slots therein extending from the free edge of said side walls for alignment with the slots in said cup, said tray receiving said spliced wires being inverted into said cup, and
- a cover adapted to matingly and threadably engage the threads on said cup to urge said tray, when inverted, into said cup to encapsulate a splice within said cup.
A re-enterable moisture-resistant closure for conductor splices between service wires having an insulating sheath and grounding shield, said closure comprising
- a shallow cylindrical cup having a circular recessed bottom wall and a cylindrical side wall formed with threads adjacent the open end of the cup and said side wall having a plurality of slots extending from the open end of the cup toward the bottom wall,
- a sealant substantially filling said cup,
- a shallow cylindrical tray having a generally circular bottom wall, having an opening therein and a diameter less than the diameter of the bottom wall of said cup, cylindrical side walls extending from said bottom wall, said side walls having a plurality of slots therein extending from the free edge of said side walls toward said bottom wall, and a plurality of parallel baffles supported from the bottom wall and projecting toward the open side of said tray and positioned adjacent said slots, said baffles having cable-receiving slots therein,
- a spring compression reserve conductive contact element supported on said tray and between pairs of said baffles for receiving the cables to be spliced, said contact element comprising spaced multiple-slotted planar legs providing spaced opposed inner and outer wire-receiving slots, wherein the wire-receiving slots in said outer contact element leg adjacent said side walls are in-line with and greater in width than the corresponding slots of the inner leg, which wire-receiving slots are adapted to receive and resiliently engage said sheath and shield of said service wires, respectively, and
- a cover adapted to matingly and threadly engage the threads on said cup to urge said tray, when inverted, into said cup to enclose a splice within said cup and retain the sheaths of said cables in said tray.
A re-enterable moisture-resistant closure for conductor splices between preconnected wires of a cable, said closure comprising
- a shallow cup having a bottom wall and a cylindrical side wall formed with threads adjacent the open end of the cup and said side wall having a plurality of wire-receiving slots extending from the open end of the cup toward the bottom wall,
- a sealant substantially filling said cup,
- a tray having a size to receive the conductor splices and having a size to fit within said side walls of said cup, said tray having a bottom wall and side walls, said side walls having a plurality of wire-receiving slots therein extending from the free edge of said side walls for alignment with the slots in said cup and having spaced parallel baffles adjacent said wire-receiving slots to impede the flow of sealant through said slots, said tray receiving said spliced wires being inverted into said cup, and
- a cover adapted to matingly and threadably engage the threads on said cup to urge said tray, when inverted, into said cup and sealant to encapsulate a splice within said cup.
