  • Patent number: 5199891
    Abstract: An electrical connector (4) terminated to signal wires (SW) of a shielded electrical cable (C) having a drain wire (DW), has an insulating housing (8) containing electrical terminals having contacts (40) electrically connected to the signal wires of the shielded electrical cable (C). A metal shield (14) covering the lower part of the housing (8) has a grounding clip (48) connected to the rear wall (28) of the shield (14) by means of a strap (62). The grounding clip receives an end portion of the cable (C) from which the signal wires (SW) extend to the contacts (40) of the connector (4). The drain wire (DW) is wound in a circuitous path about tabs (58) of the grounding clip (48). The grounding clip can be bent about the strap (62) to line in a channel (36) between two rows of the contacts (40) of the connector (4), after the grounding clip has been wound about with insulative tape (T).

  • Patent number: 5089666
    Abstract: A novel cable for computerized monitoring system comprises at least one outer jacket of plastic abrasion resistant material, one inner layer of fiber reinforcing material and another jacket of plastic abrasion resistant material. The end which is intended to be connected to the tool has a clamp to hold the fiber reinforcing material in place and prevent the fiber reinforcing material from being damaged. The clamp is a hollow cylinder about 1 inch in length with a flange, is internally threaded and is provided with at least one, preferably four grooves. When the clamp is snapped over the end of the cable, the threads engage the plastic material of the outer jacket and the reinforcing material is held in the grooves.

  • Patent number: 5041007
    Abstract: A base-bar type electrical connector, comprised of a base, an electrical contact assembly, a ribbon cable fastener and a stress eliminator. The electrical contact assembly is comprised of a plurality of conductors fastened in the base at the bottom with forked terminals projecting over the top surface of the base so that a ribbon cable can be placed thereon and squeezed by the ribbon cable fastener to force the forked terminals to pierce through the ribbon cable permitting the conductors in the ribbon cable to electrically retained at the fork of the forked terminals. The stress eliminator has two hook portions respectively hooked up with the base at two opposite ends so as to firmly secure the ribbon cable fastener to the base against any possible stress. The base has a dovetail groove at the bottom conveniently for mounting on a bus-bar main track through dovetail joint to electrically connect the ribbon cable to a bus-bar.

  • Patent number: 5037324
    Abstract: A retainer prevents the accidental separation of mating plug and socket connectors on electrical cords, or protects the connectors from inadvertent unsafe use. The retainer includes a housing which is open at one end and has a slit running along its length. An electrical cord is inserted into the slit, and the housing is moved along the cord so that the connectors enter the housing through the open end. The slit can be spiral and/or helical to reduce the possibility of the cord inadvertently coming free. A cover also having such a slit is placed on the other electrical cord and moved toward the open end of the housing. Interfitting structures removably secure the cover to the housing, thereby preventing separation of the plug and socket connectors. The interfitting structures can be arranged to engage at any point along a length span.

  • Patent number: 5030111
    Abstract: A strain relief member of sheet metal is disposed within the housing of a modular connector having a locking bar which ordinarily is crimped into locking engagement with the wires of a multi-wire cable. With such an arrangement flexure of the wires occurs at the locking bar and the wires break thereby breaking the connection provided by the connector to equipment connected to the cable. The strain relief member has a tray portion over which the wires extend to contacts located near one end of the housing. A stem extends rearwardly from the tray portion out the housing and has arms which are crimped around the cable thereby providing strain relief. The tray has a slot therein which is disposed in alignment with the locking bar. When the locking bar is crimped, it fastens the strain relief member to the housing.

  • Patent number: 5007856
    Abstract: Housings for terminations or interconnections of flat electrical cable have integral cable-clamping means to compensate for variations in cable thickness at cable exits and can accommodate one or two cables at an exit. The cable-clamping means are integral cable-engaging platforms which upon cable surface engagement as the pair of housings are secured together, are deflectable against spring bias into respective transverse relief slots therebehind. The cable-engaging platforms remain in compression against the one or two cables at the cable exit and provide insulation, vibration resistance and strain relief, protecting the termination or interconnection site.

  • Patent number: 4982124
    Abstract: The stator is made of laminated stampings having congruent outlines defining the central opening for a rotor and also defining pole pieces which include horn-like portions spaced from the main body of the stamping to define winding slots for the coil. Each end of the assembly has a terminal board which has an outline generally congruent with the laminations. Two terminals are mounted in the supports carried by the terminal board adjacent each pole piece. The ends of the wire of each coil are led across the adjacent terminal, then back between the terminal and a tang formed from the terminal. Then the tang is pressed against the terminal and wire, and fused to complete the connection.

    Abstract: A cord receiving and retaining groove in the back surface or web of a telephone set base has one or more cord retaining formations spaced along the groove. Two spaced parallel walls extend inward from the groove, away from the back surface. A cantilever member is formed in each wall, the cantilever member integral with the wall at its fixed end and extending to a free end in the groove. The cantilever members are in opposition. A projection is formed on the free end of each cantilever member, the projections extending towards each other. A cord is pushed into the groove and snaps past the projections on the free ends of the cantilever members. The cantilever members are given sufficient lever length for ready deflection by the walls extending from the groove. The walls permit flexing of the cantilever members over a longer length than if the cantilever members were formed only in the walls of the groove.
