  • Patent number: 6093892
    Abstract: An improved automatic length-adjusting end fitting for a cable assembly consisting of a conduit and a wire slidably positioned therein reacts to increases in the length of the wire and/or decreases in the length of the conduit by automatically lengthening the conduit to thereby take up a portion of the slack in the wire and return the cable assembly to its desired condition. The fitting includes a hollow housing and a cylindrical core disposed therein for sliding and rotating movement with respect to the housing. The conduit is connected to the end of the core and the wire extends completely through the core and housing. The outer surface of the core has three recesses, each of which forms a series of stair-step notches. Three axially aligned ridges are disposed on the interior surface of the housing engage respective notches, depending on how far the core is inserted into the housing.

  • Patent number: 5869784
    Abstract: Covered wires are overlapped with each other at an overlapping portion and pinched by a pair of resin chips. Cover portions are melted by ultrasonic vibration and conductive wire portions are conductively contacted with each other by pressing from outside of the resin chips. A pair of the resin chips are melt-fixed to seal the overlapping portion S. The resin chips have main melting portions which are melted with each other to pinch and seal the overlapping portion S, auxiliary melting portions which are melted with each other such that cover portions of covered wires introduced from the main melting portions are pinched and cover portion removing portions formed in the auxiliary melting portions to melt and extrude the cover portion. Thus, by this covered wire connection structure, it is possible to provide an excellent melting performance and achieve enhancement of melting force between the resin chips and improvement of covering performance for conductive wire portions.

  • Patent number: 5854444
    Abstract: An environmentally sealed splice kit for splicing together a shielded cable which is fully immersion protected and which is installed using only hand tool without using heat generating sources. The splice kit has a pair of crimp sleeves which are coupled to a separate wire braided end of the shielded cable. A jumper wire is coupled to each crimp sleeve for providing electrical continuity between each wire braided end of the shielded cable. A crimp ferrule is coupled to each wire braided end of the shielded cable for holding and connecting each crimp sleeve to each wire braided end of the shielded cable. Conductor splices are used for splicing together each center conductor of the shielded cable to be spliced together. A dielectric spacer is used for separating and providing an isolating medium between each center conductor to be spliced together and the jumper cable.

  • Patent number: 5852257
    Abstract: An optic module contains a flexible circuit board forming a cable which connects between an optical sub-assembly and a rigid interconnect structure within the optic module. One end of the cable includes lands proximate to through holes for soldered connection to pins which extend from the optical sub-assemblies. At the other end of the cable leads extend across interconnection pads on the surface of the rigid interconnect structure for soldered connection. The top surface of the interconnect pads is 10/90 (Sn/Pb) solder to provide a high temperature soldered joint. Solder flux can not be used because cleaning solvents would contaminate the interconnect structure. An atmosphere of formic acid mixed with nitrogen surrounds the lead and pad and a fluxless solder joint is formed.

  • Patent number: 5821461
    Abstract: A waterproof splice for use in connecting two multiconductor electric cables having jackets of different insulation material and a method of making the splice are disclosed. The splice consists of a mechanical electrical connection between the conductors, a mechanical bond formed on the insulation of one of the conductors and a sheath of insulation material molded over the splice and adjacent cables. The sheath bonds with the jacket of one cable and the mechanical bond formed on the insulation of the other cable. The mechanical bond is a seal ring of elastomeric material that is compressed between glands to move the seal ring into sealing engagement with the conductor. The disclosed splice is both strong and waterproof in spite of the poor bonding characteristics between the two different insulation materials on the two conductors. The splice is appropriate for cables having surface, subsurface and underwater applications and is specifically designed for use in conducting seismic surveying operations.

  • Patent number: 5770818
    Abstract: A cover plate for covering exposed conductive wires of a flat cable is attached to a surface of an attaching plate for holding the flat cable, and insert molding is performed in such a manner that the cover plate is included. Therefore, direct contact of a portion of flows of synthetic resin for use in performing insert molding that flows along a surface of the attaching plate for holding the flat cable with conductive wires of the flat cable can be prevented. Moreover, if the synthetic resin introduced into another surface of the attaching plate for holding the electric wires flows in joint portions between the conductive wires, the conduction wires of the flat cable are pushed against the cover plate due to the flow of the synthetic resin so that the conductive wires of the flat cable are supported. Thus, the conductive wires of the flat cable can be protected from excess stress when the insert molding operation is performed. Thus, breakage of the conductive wires of the flat cable can be prevented.

  • Patent number: 5760332
    Abstract: An enclosure for protecting cable splices having a pair of outer shells, a pair of inner shells, an extender between the pairs of inner and outer shells, and clips inside the inner shells for resisting forces applied to the spliced cables that would tend to separate the spliced cables. The cables to be spliced are passed through a hole in the outer shell, inner shell, and compressible grommets in the inner shells, and space for the cable splices is provided by the extender tube. As the outer shells are threaded onto the extender tube, a seal is formed around the splice by the compression of the grommets and the joining of the inner ends of the inner shells with the ends of the extender tube.

  • Patent number: 5654526
    Abstract: A coupling apparatus and method for joining together lengths of electrical conduit in a conduit system. The coupling apparatus includes a resealable port that permits lubricant to be introduced into the coupling apparatus to facilitate wire pulling through a conduit system and to reduce strain on the insulation material of the wire. The coupling apparatus is a generally T-shaped tubular structure and includes a pair of axially-aligned conduit receiving openings which define an inlet and an outlet, respectively. The inlet and outlet openings are spaced a distance apart from one another by a central chamber. The central chamber has an inner tubular diameter substantially equal to the inner tubular diameter of the conduit to be joined in order to provide a smooth transition for wire being pulled through the coupling apparatus. The resealable lubrication port is defined by a vertically oriented tubular leg portion and removable threaded plug which are joined to a middle section of the central chamber.

  • Patent number: 5619015
    Abstract: A cable end with its terminal or connector is maintained in a curved installed position with the aid of a bent retaining jacket (25A). The jacket is preferably a corrugated metal hose having one end formed into a bushing that is clamped in place on a support body of the connector or terminal together with other cable components such as a protective hose system. The bend maintaining jacket has an inner diameter that is larger than the outer diameter of the protection hose system of the cable so that the jacket may be freely pushed over the cable end prior to the installation of the terminal or connector. The opposite end of the jacket remains open or rather unconnected, thus enabling the jacket to accommodate any twists that result from bending the cable end. Although the jacket is bendable, it has a bend retaining characteristic that will not change its curved configuration in response to impacts, vibrations, or the like. Only an intentional renewed bending can bring the jacket into a new curved shape.
