In the wire harness 1 commercialized as described above, confirmation of connection quality according to specifications and continuity inspection including the braided wire 9 are performed before shipment. The continuity inspection is usually performed by a continuity inspection device 16 such as a tester, and the electrode probes 17 and 18 are connected to the respective connectors 4,
By contacting the corresponding terminals between 5 and 6, the presence or absence of disconnection or the presence or absence of a short circuit between the wires is detected.

In this case, for the electric wire 8 whose both ends are connected to the connection terminals in the connector, the electrode probes 17 and 18 are inserted into the terminal insertion holes 20 from the front of the connector.
By inserting into the terminal and making contact with the corresponding terminal, for example, a continuity test or the like can be performed over the entire length of the electric wire.

However, in the case of the braided wire 9, since the other end side is the cut-off end 11 and is covered with the insulating tape or the like as described above, the electrode probe 17 or 18 cannot be directly contacted. Therefore, in order to carry out a continuity inspection over the entire length of the braided wire 9, after the insulating coating 14 is once peeled off, the braided wire 9 previously twisted into a filament is
It is performed by sandwiching it with a crocodile clip to which one of the electrode probes is connected. However, in such a countermeasure, the rewinding work for rewinding the insulating coating 14 to the original state may be forgotten after the inspection, and the cut end 11 of the braided wire 9 may be left exposed. Further, even if the rewinding work is not forgotten, the above-described inspection process causes a decrease in the productivity of the wire harness.

Therefore, as shown in FIG. 5, the braided wire 9 is inspected only at the connection portion with the connection terminal in the connector, and the continuity inspection for the entire length of the braided wire 9 is often omitted. For this reason, since the braided wire 9 is only subjected to the continuity test in a very limited range indicated by a range B in the figure, the quality assurance range of the shielded wire is narrow and the reliability of the test is low.

Then, the cut end of the braided wire twisted into the wire and inserted into the tubular body of the end processing cap is grasped by the locking means having an elastic force mounted on the tubular body, and therefore, the hand is released. It does not fall off easily and is easy to handle. Then, the end processing cap having the cut end inserted is vertically attached to another covered electric wire or the like and taping or the like is performed from the outer peripheral side of the end processing cap, whereby the electric wire bundle can be firmly fixed. .

In addition, taping or the like applied on the end portion processing cap is performed only by taking care not to close the other end opening of the end portion processing cap, and the electrode for the continuity inspection in the continuity inspection device. The probe can be brought into electrical contact with the cut end of the braided wire from the other end opening of the tubular body of the end processing cap at any time, and the continuity test for the entire length of the braided wire whose one side is the cut end, Easy and reliable implementation. Therefore, in a wire harness in which one side of the braided wire of the shielded wire is treated as an open end, the continuity inspection can be easily and reliably performed over the entire length of the braided wire without troublesome work. The workability of the inspection work can be improved, the productivity of the wire harness can be improved, and the reliability of the continuity test can be improved at the same time.

Moreover, in the end processing cap, the locking means for gripping the wire inserted in the tubular body is provided at one end side of the tubular body, and extends from the peripheral wall of the tubular body toward the center of the tubular body. If the wire rod inserted into the tubular body is biased toward the center of the tubular body by a plurality of tongue-shaped pieces that extend and have an elastic action, various types of end treatment caps of a single type can be used. It can be applied to the cut-off end of a shielded electric wire having a thickness, and the number of parts can be reduced to reduce the manufacturing cost. Further, in the case where the inner diameter of the tubular body of the end processing cap is configured such that the other end side is expanded, it becomes easy to insert the electrode probe of the continuity inspection device from the opening on the other end side, and the continuity inspection work is performed. Can be further facilitated.
