  In general, in order to connect a shielded wire covering a wire with a braided wire to a shielded connector, that is, to manufacture a wiring harness with EMI (electromagnetic interference) countermeasures, the following procedure is used.

  10 to 16 show a series of manufacturing steps according to the prior art for manufacturing the wiring harness described above.

  The electric wire 1 shown in the perspective view of FIG. 10 is a shielded wire that covers the electric wire with a braided wire. The electric wire 1 includes a plurality of core wires 1a, a cylindrical metal braided wire 1b covering these core wires 1a, and an insulating sheath 1c covering the braided wire 1b. In the electric wire 1, several core wires 1a are bundled with an insulating tube 1d. One of the several core wires 1a is a bare electric wire that serves as a ground wire. Further, the electric wire 1 is provided with a drain wire 1e formed of a braided wire 1b and a stranded wire to be grounded.

  First, in order to lay the wiring harness on the device, the length of the electric wire 1 shown in FIG. 10 is adjusted, and the terminal of the electric wire 1 is cut (adjustment and cutting step).

  Next, as shown in the perspective view of FIG. 11, the insulating sheath 1c is peeled (striped) at a predetermined distance from the end face of the electric wire 1 (sheath peeling step). In this sheath peeling step, the braided wire 1b is also cut at a predetermined distance from the end face of the electric wire 1 (braid cutting step).

  Next, as shown in the perspective view of FIG. 12, the braided wire 1b is reversed onto the insulating sheath 1c (braid reversing step). Next, as shown in the perspective view of FIG. 13, the insulator covering the core wire 1a is peeled (striped) at a predetermined distance from the tip of the core wire 1a (insulator stripping step).

  Next, as shown in the perspective view of FIG. 14, the copper foil tape 1f is wound around the inverted braided wire 1b so that the braided wire 1b is not dispersed. The step of winding the copper foil tape 1f around the braided wire 1b can be omitted.

  Next, the core wire 1a is connected to a contact (not shown). For example, the core wire 1a is crimped to a contact (not shown) (terminal crimping step). This contact is mounted on the shield connector 2 shown in the perspective view of FIG.

  In FIG. 15, the shield connector 2 includes an insulative housing 21 in which contacts are mounted, and a metal shell 22 surrounding the housing 21. The shell 22 has a crimp barrel 22a that opens in a U-shape. In addition, a pair of clamp by patent document 1 has a function similar to the crimp barrel 22a.

  As shown in FIG. 15, when the crimp barrel 22 a is crimped (crimp process) as shown in the perspective view of FIG. 16 from the state where the terminal portion of the electric wire 1 is in contact with the inside of the crimp barrel 22 a, the wiring harness A series of steps for manufacturing the is completed.

  Also, the wiring harness 90 shown in FIG. 16 can firmly hold the terminal portion of the electric wire 1 to the shield connector 2. The crimp barrel 22a corresponds to the crimp according to Patent Document 1 as a function. Moreover, since the braiding wire 1b and the metal shell 22 are electrically connected, the wiring harness 20 has improved shielding performance.

  However, a conventional process for manufacturing a wiring harness includes a sheath stripping process (see FIG. 11) for peeling the insulating sheath 1c so as not to damage the braided wire 1b, and a braid for reversing the braided wire 1b on the insulating sheath 1c. And an inversion step (see FIG. 12).

  Peeling only the insulating sheath 1c without damaging the braided wire 1b requires considerable skill, and this sheath peeling step has a problem that it is difficult to improve the yield. Including the sheath stripping process and the braid reversing process in the manufacturing process has become one of the factors that hinder the manufacturing cost reduction of the shielded wiring harness.

  If the braided wire and the metal shell can be electrically connected without including the above-described sheath stripping process and braiding reversal process, the quality of the shielded wiring harness can be improved and the manufacturing cost can be reduced.
