Further cables may be installed subsequently through the other ports and/or ports which are already used may be opened and re-used.

Abstract: A waterproof wire-sockets electrical junction cover suitable for use in wet environments includes a chamber to house the wire-sockets electrical junction. Sealable passages on one end of the chamber allow electrical wires to pass into the chamber. On the other chamber-end, a sealable port allows the wire-sockets itself to enter the chamber. The electrical wires are mechanically and electrically joined using the wire-sockets. The resulting junction is then drawn through the aforementioned sealable port into the chamber. The port is closed, thereby completely watertight sealing the wire-sockets electrical junction.

Abstract: A connector device for splicing two conductors includes a pair of joined body sections provided with axially offset cable conductor holes leading to an intermediate cavity. A grip element with the cavity, having one or more helical coils has its opposite ends anchored relative to the opposed end faces of the two body sections. Two cable conductors are electrically and mechanically joined by inserting the conductor ends through the body sections and into the cavity, within the confines of the grip element coils following which, twisting of the body sections relative one another constricts the grip element convolutions tightly about the contained conductor ends. The interlock may be further enhanced by the inclusion of a knobbed lock post disposed within the connector cavity and which assists in deforming the conductor ends as the coil grip element is constricted thereabout.

Abstract: A reenterable splice closure and method of making and applying the same is disclosed having a pair of mating housings with an internal rigid telescoping support collar located at the seam between the two housings, and a first heat shrinkable sleeve surrounding and sealably shrunk down over the mating ends of the housings sealing the seam and extending the end of one housing for heat shrinking down onto cables leading from a splice enclosed in the housing. The enclosure can be reopened by cutting the splice along a line over the seam, and after the closure has been reassembled with the housings again in mating position, a new heat shrinkable sleeve is applied down over the cut in the first shrinkable sleeve.

Abstract: The long term water intrusion resistance of cable splice systems that use a gelable encapsulant that is pressurized prior to geletion can be improved by providing pressurization means that maintain the pressure on the cured encapsulant above a given pressure p.sub.2 >p.sub.o, where p.sub.o is the ambient pressure. Absent such pressurization means, the pressure on the encapsulant typically decreases with time due to creep or relaxation of nominally rigid components, e.g., a polymeric closure around the encapsulated splice, or varies due to differential thermal contraction. The pressurization means comprises one or more energy storage elements, e.g., an elastic member such as a spring, or a volume of compressed gas.

Abstract: A closure for a cable splice is disclosed which comprises a main sleeve and two end structures. One end structure is secured to the sleeve by means of a locking ring screwed onto a cap of the end structure. The sleeve has an internal flange and the cap has an external flange which lies adjacent the flange of the sleeve. Engagement between the flanges prevents the end structure being withdrawn from the sleeve. The end structure is connected to the sleeve by means of a split clamping ring which is held in place by a tightening ring. Once the ring has been loosened and slid back, and the clamping ring and tightening ring removed, the sleeve can be slid back over the cable to provide access to the splice.

Abstract: A splice joins two pushing and pulling cables. Each cable has a plurality of gripping members defining a longitudinal cavity, a bendable power line housed in the cavity and elongated tensile elements enclosed and compressed by the gripping members. The adjacent ends of the tensile elements are connected by tensile element splices. Adjacent ends of the power lines are connected by a power line splice. A plurality of splice blocks are located end to end along the longitudinal axis, and enclose and compress the tensile element splices and the tensile element. The splice blocks define a longitudinally extending chamber housing the power line and the power line splice in a relatively stress free state.

The central passage has spaced shoulder means to mate spaced shoulder means on the male contact pin and female socket to retain them in the boots. Annular, longitudinally extending seal surface sealingly engage when the boots are mated and cooperating stop surface means and locked surface means engage when the boots are mated.

Abstract: A high voltage electrical component can be insulated by placing such component into a first sleeve of preformed insulative material dimensioned to receive and telescope over the component. An internal abutment in the first sleeve positions the component for reception of both the first sleeve and component by a second sleeve of preformed insulative material dimensioned to receive and telescope over the first sleeve and component within. An internal abutment in the second sleeve further secures and centers the component and the first sleeve for subsequent encapsulation by insulative materials used with injection molding to form an outer insulative jacket. Once encapsulated within the insulative jacket the telescoping sleeves form a convoluted path outwardly from the component to the exterior of the jacket thereby minimizing high volt leakage.

Abstract: A casing provides a hermetically sealed enclosure around a joint between two elongate substrates. The casing comprises two generally cylindrical members, each of which comprises a first open end section and second open end section. The first end section includes a heat-shrinkable sealing member which can be shrunk by heat to form a hermetic seal between the first end section and a substrate passing therethrough. The second open end section of each member can be hermetically sealed to the second open end section of the other member. There is a generally cylindrical flexible connecting section between the first and second end sections. This connecting section can be deformed to permit relative axial movement between the first and second open end sections to provide access to the joint.

Abstract: A splice case housing electrical splices between two cables where the splices are immersed in an oil sealant having a specific gravity greater than water. The case includes holes located above the splices for receiving the electrical cables. Since the oil is heavier than water, if water were to enter the splice case, it would be above the oil and splices, thereby causing a hydraulic force on the oil, causing an even more intimate seal of the oil around the splices.
