  • Patent number: 5537742
    Abstract: There is provided a method for joining the buss wires of a pair of flexible cables by splicing and encapsulating the ends of the cables together. This method involves the splicing of the two cables together by stripping oppositely disposed ends of the two cables such that the buss wires are left exposed. The exposed wires are inserted into respective ends of a connector tube formed of a material having a similar melting point, tensile strength and electrical conductivity properties to the buss wires disposed therein. Both ends of the connector tube are then welded to the oppositely disposed buss wires. Thereafter, the welded wires are encapsulated within an polymer encapsulation layer which overlaps with portions of the flexible sheath that had not been stripped. The polymer encapsulation layer is preferably one which exhibits a similar melting point and tensile strength to the flexible polymer sheath.

  • Patent number: 5346327
    Abstract: A fastener for splicing wires and the like is mace by forming a tubular sleeve of spring material such as phosphor bronze. In its unrestrained shape, the tubular sleeve is too small to receive the wires, but the tubular sleeve is expanded elastically and held expanded by solder, so that the wires can be inserted. Upon the application of heat the solder melts, flowing into the joint and allowing the sleeve to spring back to its original size or at least to the diameter of the wires. The fastener can be mounted on a stud to provide a replacement for the familiar solder cup terminal. An expanded sleeve can be placed around a piece of heat shrinkable tube. When heated, the tube and the sleeve contract, the sleeve reinforcing the tube giving a much greater compressive force during shrinking. The sleeve then becomes a metallic protector for the tube.

  • Patent number: 5142763
    Abstract: Metal pipes containing optical fibers are connected to each other directly or indirectly by use of a sleeve. In case of using the sleeve, the sleeve is connected at one end to one of the metal pipes, after the optical fibers are connected. Then, the sleeve is elongated by a predetermined length, so that the sleeve is connected at the other end to the other metal pipe. Consequently, no tensile stress resides in the connected optical fibers in the connected structure. When the metal pipes are connected directly to each other, one or both of the metal pipes are elongated, after the optical fibers are connected. Then, the metal pipes are connected by use of the elongated portions. Consequently, the same result is obtained as using the sleeve.

  • Patent number: 4597620
    Abstract: An electrical connector assembly comprising first and second mateable connectors is disclosed herein. The first connector includes a collet having an expandable mouth in a concave interior, and the second connector includes a convex member, such as a sphere, which is substantially complementary in shape to the concave interior surface of the collet. The concave interior of the first connector, and the convex member of the second connector surround a male pin and female barrel connector, respectively. The male pin and female barrel mate when the convex member of the second connector is inserted into the concave interior of the first connector. Additionally, the collet is split along its longitudinal axis in order to form a plurality of collet fingers which are closeable by means of a collet which is movable along the outside surface of the collet. A water-tight seal between the male pin and the female barrel of the connectors is accomplished by an O-ring disposed in the mouth of the female barrel.

  • Patent number: 4508404
    Abstract: A method and apparatus are disclosed for remotely connecting, disconnecting and reconnecting a flexible communication member between two spaced apart bodies which are in predetermined relative positions to one another within given tolerances, and more particularly, to the connecting of an electrical connector to a carried spacecraft from an orbiter while providing for a minimum transfer of energy therebetween. A remote actuation of an electrical connector between two bodies is accomplished by driving an extendable member carrying a detachable connector from one of the bodies into mating contact with a fixed connector on the other body. A locking means associated with the other body retains the detachable connector in such mating contact while the extendable member is withdrawn. A flexible cable is first secured between said one of the bodies and the detachable connector.

  • Patent number: 4503283
    Abstract: In a cable stub assembly (20) which is used to interconnect two cables (22 and 24), at least one of which is pressurized with a gaseous medium, a portion of a plastic jacket is removed from an interior portion of a length (31) of cable to expose conductors (33--33) of a core (32). Heat shrinkable sleeves (61 and 66) each of which comprises an irradiation cross-linked polyolefin material are positioned over the jacket of the cable on each side of the interior portion from which the jacket has been removed. The heat shrinkable sleeves are caused to contract about the cable jacket. Inner surfaces of the sleeves are coated with an adhesive material which is helpful in providing a sealed engagement of the sleeves with the jacket. A length of tubing (81) is disposed about the cable jacket and the contracted sleeves. A polyurethane filling material (82) is introduced into the tubing and is adhered sufficiently to the sleeves to prevent substantially the escape of the gaseous medium from the at least one cable.

  • Patent number: 4484022
    Abstract: A sleeve, terminal body, plug body, or the like receives tubular or ring-shaped, normally solid but thermoplastic filler elements, being traversed by a cable or conductor, particularly a portion from which insulation has been stripped. A plunger-like element receives also the cable or conductor and is inserted in one end of the sleeve, or body, the other end being closed by another plunger or body structure. Upon heating, the filler element melts and the plunger or plungers are forced further in to cause melted filler material to fill all voids; the deformed material resolidifies and seals and bonds all parts together.

  • Patent number: 4473942
    Abstract: Optical fibers are cleaved with high precision by a technique that yields flat endfaces that are perpendicular to the axis of the fiber within 1 degree, and typically within 0.5 degree. This is very advantageous for obtaining low loss splices of fibers, especially single mode fibers. In the present technique, a fiber is secured in two linearly aligned chucks in a sequence that allows one end to rotate unconstrained to minimize tortion. An axial tension is then applied in the fiber, which is next scored. The fiber then typically breaks, but cleaving can be promoted by applying further tension, or introducing moisture, if necessary.

  • Patent number: 4384404
    Abstract: The invention relates to an article suitable for making an electrical connection between two electrical conductors, for example an earth conductor and the outer conductor of a coaxial cable. The article comprises a first, heat-shrinkable, sleeve (1), a quantity of solder (2) positioned within the sleeve, and a second sleeve (5) an outer surface of which, together with an inner surface of the first sleeve, forms a passage for receiving the earth conductor. Stop means are provided for axial location of the earth conductor. On shrinking of the sleeve and fusing of the solder, an electrical connection can be made between an earth conductor received, in use, in the passage and the outer conductor of a coaxial cable received, in use, in the first sleeve but not in the passage.

  • Patent number: 4375720
    Abstract: Cable ends (1 and 2) are to be joined. The cables are armored by stainless steel sheaths, and have two conductors (9 & 11, and 8 & 10 respectively) insulated by means of compressed mineral insulation (14). The cables are typically for thermocouples and have an outside diameter of a few millimeters. Joining proceeds as follows: The cable ends are reduced in diameter by swaging, e.g. with initial conical portions (5,4) followed by smaller diameter portions (7,6). The ends of the swaged portions are stripped to reveal the conductors which are joined end-to-end by welding. A longitudinally slotted length of tubing (3) is placed around the join, and the tubing is filled, via its slot, with powdered mineral insulation. The length of tubing 3 is then closed by welding, and the entire join is drawn down around the join to ensure that the entire joined cable is of uniform outside diameter.
