  • Patent number: 6170152
    Abstract: Cylinders are arranged in such a manner that they correspond to a plurality of pressure-blades by one-to-one, and desired pressure-blades are pushed downward by the corresponding cylinder rods, so that the desired pressure-blades are protruded from and fixed at the lower ends of the residual pressure-blades. The thus arranged pressure-blades are lowered with respect to the connector. Then, only the pressure-blades protruding from the lower ends of the other pressure-blades can conduct the operation of pressure-connection. Due to the foregoing, after the electrical wires F have been connected to the pressure-terminals of one connector all at once, in the pressure-connecting process of the other connector, only when the desired pressure-blades are selected and the selected pressure-blades are moved along the arrangement of the pressure terminals of the other connector, the wire harness of cross-wiring can be manufactured.

  • Patent number: 6021566
    Abstract: Both ends of a plurality of parallel electrical wires are respectively connected to the connectors with pressure by a pressure-connecting and wiring machine into which the plurality of electrical wires are introduced, and the thus introduced electrical wires are sent to the electrical wire pressure-connecting section via the electrical wire cutting section. At this time, the connectors are successively fed to the electrical wire pressure-connecting section of the pressure-connecting and wiring machine in the direction parallel with the arrangement of the pressure terminals. After the electrical wires have been connected to the connector with pressure, the pressure-connected electrical wires of a predetermined length are drawn out from the pressure-connecting and wiring machine. Then the pressure-connecting and wiring machine is turned round the vertical axis by an angle of 180.degree., and the electrical wires, which have been drawn out before, are connected to the other connector with pressure and cut.

  • Patent number: 5819621
    Abstract: An electric cable guiding device includes a fixed guide block and a movable guide block. A projected round surface is formed in the fixed guide block, and an indented round surface is formed in the movable guide block. In addition, a groove is formed in the indented round surface. At the time of guiding an electric cable, the movable guide block is fitted in the fixed guide block. In this state, the indented round surface and the groove constitute an electric cable guide path. The electric cable is fed into the electric cable guide path by rollers. Consequently, the electric cable is guided in a U shape along the electric cable guide path. The front end of the electric cable drawn out of the electric cable guide path is clamped. Thereafter, the movable guide block is moved to an electric cable measuring position that is spaced apart from the fixed guide block by a predetermined distance. In this state, the electric cable is fed by a required length.

  • Patent number: 5609463
    Abstract: Recesses 12 are formed on an upper surface 10a of a turntable 10 detachably mountable on a support member 20. The recesses 12 are arranged at a pitch of a specified angle .theta. on a plurality of concentric circles C1 to C4 centered on a longitudinal axis 11. The turntable 10 is slid along an x-axis by an air cylinder 80 and is intermittently rotated by the specified angle .theta. by an air motor 40. In this way, a desired recess 12 can be moved to a receiving position P. The waterproof plugs can be securely supplied. A preparation for changing the kind of the waterproof can be made only by replacing the turntable, with the result that the preparation can be easily made within a short period of time.

  • Patent number: 5606909
    Abstract: A plurality of wires W are caused to hang downward substantially in U-shape, such that the ends of wires W to be bound together are closely fixed. The end portions of a plurality of fixed wires W are positioned in the vertical direction by straightener 16 and holder 17 and automatically bound with tape by tape winder 18. The binding position can be determined in the vertical direction, thereby obviating the need to lay wires W over their entire lengths in the conveying direction of the production line. As a result, the distance to lay wires W can be shortened by the hanging amount of wires W, thereby considerably reducing the space required for the installation of the wire binding apparatus.

  • Patent number: 5575060
    Abstract: The invention provides a terminal inserting drive apparatus for inserting both terminals of a wire into a corresponding terminal cavities in cooperation with a housing carrying apparatus (150). The terminal inserting drive apparatus has a pair of hand sections (1615 and 1616) for, respectively, gripping both ends of the wire (W) with terminals; a conveying section (1611 and 1612) for, individually, conveying the hand sections (1615 and 1616); and a conveying control device (100) for operating the conveying section (1611 and 1612) so as to convey simultaneously both hand sections (1615 and 1616) normally and operating the conveying section (1611 and 1612) so as to convey both hand sections (1615 and 1616) sequentially when both hand sections (1615 and 1616) would interfere with each other.

  • Patent number: 5575058
    Abstract: A pallet 71 is provided to array connector housings C side by side in correspondence with the side by side alignment of an aligning unit A in a plurality of rows. A conveying unit 74 includes a plurality of actuators 74a for holding a row of connector housings C arrayed side by side on the pallet 71. Conveyors 74b, 74c and 74d are further provided to carry actuators 74 a integrally to the aligning unit A.In changing the combination of the connector housings to be handled, only the pallet needs to be replaced without necessitating a change in a conveying unit. Accordingly, the conveying unit 74 can be widely used for a variety of connector housings, and labor and time required for replacement can be reduced. Further, installation can be of smaller size compared to the prior art guide member for guiding the connector housings C in sliding contact therewith, leading to a considerable reduction in installation cost.
