  • Patent number: 6148514
    Abstract: A process and system for repairing electromechanical cables having an external armor wire layer using a butt welding technique and an arc vanishing machine. A short (break) in a cable having both an external and inner helically wrapped wire layer over an inner conductor(s) is located using conventional techniques. After the inner conductor(s) and inner wrapped layer are repaired (i.e., spliced), the outer wire layers are reconnected using a butt-end welding process and form individual arc shapes. The cable automatically passes through dies on headers to vanish (displace) each of the arcs to the end of the cable. A safety system activates an alarm to shut down the system when a jam occurs before any cable wires break. The system is reactivated after the jam is cleared.

  • 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: 5347089
    Abstract: An arrangement for enclosing a branch-off between a pair of cables (2,3,4) comprises a dimensionally recoverable sleeve (5) which can surround the branch-off, and one or more clips (6) which can be positioned about opposed walls of the sleeve to divide the sleeve into channels for the cables. The or each clip (6) is of unitary form and has a pair of legs (8) that are splayed outwardly to facilitate positioning of the clip over the sleeve walls. The or each clip is deformable so that the legs can be forced towards each other after the clip has been positioned on the sleeve walls but is sufficiently rigid, at least in its deformed state, it will resist opening out of the legs under the recovery forces of the sleeve.The invention provides a relatively simple and easy to install enclosure for branch-offs in harnesses for example that are intended to be used in automotive vehicles.

  • Patent number: 5281765
    Abstract: A wiring assembly for equipment is produced at a low cost and has the same wiring connection as a flexible printed cable (FPC). Various kinds of terminal treatment processes are applied to the assembly. A circuit is formed by arranging polyurethane-insulated magnet wires 21 on a polyimide (PI) sheet 22 formed along a wiring circuit having bent, curved, and branched (jointed) portions. The formed circuit is coated with a PI sheet 23. Accordingly, an etching step such as in an FPC is not required. It is possible to produce a wiring assembly having the same function as an FPC at a low cost and to effect various kinds of terminal treatments as with an FPC. A wiring assembly having a single crossing in a circuit is formed by using insulated conductors.
