Definitions

  • This invention relates to a terminal-processed structure of a shielded cable and a terminal-processing method of the shielded cable.
  • FIGS. 8 to 10 are perspective views of an end of each conventional shielded cable, illustrating the respective steps of processing a terminal of the shielded cable.
  • a conventional shielded cable 1 comprises two cores 2, braided metallic wires 3 sheathing the cores 2, and an outer insulating member 4 covering the wires 3.
  • An inner sleeve 6 which is provided with male threads is disposed on the outer insulating member 4 of the shielded cable 1.
  • the braided metallic wires 3 are bent back on the inner sleeve 6 and core wires 5a of an external electrical cable 5 are placed on the braided metallic wires 3. Then, as shown in FIG. 10, an outer sleeve 7 which is provided with female threads is engaged with the inner sleeve 6.
  • An object of the present invention is to provide a terminal-processed structure of a shielded cable which is simple and suitable for rapid and reliable processing of a terminal.
  • Another object of the present invention is to provide a method for processing a terminal of a shielded cable in which the terminal is simple and suitable for rapid and reliable processing.
  • a terminal-processed structure of a shielded cable wherein core wires covered by a first insulating layer are sheathed by braided metallic wires on the outer periphery of the first insulating layer and are further covered by a second insulating layer on the braided metallic wires, in which:
  • the conductive sleeve-like body is a U-shaped metallic strip at first when the body is placed on the exposed, braided metallic wires on the one end of the shielded cable, and then the strip is formed into the sleeve-like body when the strip is crimped on the metallic wires.
  • the hard sleeve-like body is provided with a plurality of circumferencial grooves in the outer periphery thereof.
  • the hard sleeve-like body may comprise a pair of half parts divided axially or may be provided with a slit extending axially.
  • the invention provides a method of processing a terminal of a shielded cable, wherein core wires covered by a first insulating layer are sheathed by braided metallic wires on the outer periphery of the first insulating layer and are further covered by a second insulating layer on the braided metallic wires, comprising the steps of: exposing said braided metallic wires at one end of said shielded cable;
  • the conductive sleeve-like body crimped on the one end of the shielded cable is attached to a conductive casing by a conductive band or ring.
  • the braided metallic wires 13 are electrically communicated with the casing.
  • the hard sleeve-like body is inserted beneath the braided metallic wires after the wires are exposed at one end of the shielded cable, so that the body serves to support the exposed, braided metallic wires, and the conductive sleeve-like body is put on the braided metallic wires bent back on the second insulating layer and crimped onto the metallic wires, thereby electrically communicating and holding the conductive sleeve-like body with and on the exposed, braided metallic wires.
  • the conductive sleeve-like body is brought into contact with a casing or the like when the shielded cable is secured to the casing.
  • the shielded cable can be easily inserted into the sleeve-like body through an opening between legs of the U-shaped strip. Afterward, the U-shaped strip is crimped on the braided metallic wires.
  • the hard sleeve-like body is inserted beneath the braided metallic wires after the wires are exposed at one end of the shielded cable, so that the body serves to support the exposed, braided metallic wires, and the conductive sleeve-like body is put on the braided metallic wires bent on the second insulating layer and crimped onto the metallic wires, thereby electrically communicating and holding the conductive sleeve-like body with and on the exposed, braided metallic wires.
  • the present invention it is possible to easily insert the hard sleeve-like body beneath the exposed, braided metallic wires and to readily mount the conductive sleeve-like body on the braided metallic wires merely by crimping the body on the wires. Thus, it is possible to extremely easily effect the terminal-processing. Also, electrical communication between the conductive sleeve-like body and the braided metallic wires can be positively obtained.
  • FIGS. 1, 3 and 4 are perspective views of an end of each shielded cable.
  • a shielded cable 10 comprises a core wires 12, a first insulating layer or an insulating member 11 which covers the core wires 12 on the outer periphery, braided metallic wires 13 which sheathe the first insulating member 11, and a second insulting layer or an outer jacket 14 which covers the braided metallic wires 13.
  • a hard sleeve-like body or a plastic sleeve 20 is made of an insulating hard plastic material and has an inner diameter sufficient to receive the core wires 10 covered by the first insulating layer 11.
  • the plastic sleeve 20 has a hardness enough to bear a crimping force on a conductive sleeve-like body being a U-shaped metallic strip 30 described hereinafter.
  • the hard sleeve-like body 20 is made of an insulating hard plastic material in this embodiment, for the reason that the sleeve 20 merely serves to support the braided metallic wires 13 and need not communicate electrically with the braided wires.
  • the plastic sleeve 20 is provided with a plurality of circumferential grooves 21 on its outer periphery so that the metallic wires 13 and strip 30 bite into the grooves 21 when the strip 30 is crimped onto the wires 13, as shown in FIG. 2A. Thus, the sleeve 20 is prevented from coming out of the shielded cable 10.
  • the plastic sleeve 20 is formed into a complete cylindrical body from the beginning in the above embodiment, the plastic sleeve 20 may comprise a pair of half parts 23, 23 divided axially (FIG. 2D) or may be provided with a slit 24 extending axially (FIG. 2C), since the sleeve 20 can be brought into a complete sleeve from when it is assembled on the shielded cable 10, thereby simplifying the step of mounting the sleeve 20 on the cable 10.
  • the metallic strip or conductive sleeve-like body 30 is a U-shaped conductive metallic strip at first.
  • the metallic strip 30 has a length slightly larger than the circumference of the plastic sleeve 20 and a width of span between the legs of U-shape which is enough to receive the sleeve 20.
  • the shielded cable 10 is stripped at its one end so that at least a part of the outer jacket is removed to expose the braided metallic wires 13.
  • the plastic sleeve 20 is inserted between the first insulating layer or insulating member 11 and the exposed, braided metallic wires 13.
  • the U-shaped metallic strip 30 is put on the exposed, braided metallic wires 13 and crimped on the wires 13 so that the strip 30 can encircle the wires 13, as shown in FIG. 4.
  • the conductive sleeve-like body 30 may be held on the casing 40 to contact with it, as shown in FIGS. 7A and 7B.
  • the body 30 crimped on the one end of the shielded cable 10 is attached to the casing 40 by a conductive metallic band 41 (FIG. 7A) or a conductive metallic ring 42 (FIG. 7B). Consequently, it is not necessary to solder the braided metallic wires 13 to the casing 40 or to secure the wires 13 to the casing 40.
  • FIGS. 5 and 6 show an embodiment of a terminal-processed structure of the shielded cable which is in accordance with the present invention.
  • the plastic sleeve 20 has an inner diameter sufficient to receive the second insulating layer or outer jacket 14 on the shielded cable 10.
  • the exposed, braided metallic wires 13 are loosened and bent back on the sleeve 20 after the sleeve is disposed on the outer jacket 14.
  • the metallic strip 30 which has a span slightly larger than the outer diameter of the sleeve 20 is crimped on the metallic wires 13 bent back on the sleeve 20.
  • the shielded cable can be used in the casing in the same manner as those shown in FIGS. 7A and 7B.
