In this embodiment, the first connector12shown in the exploded perspective view inFIG.3and the second connector13shown in the exploded perspective view inFIG.4are both assembled by installing the housing bodies122,132to jigs described hereinafter. This assembly operation is substantially the same between the first connector12and the second connector13. In the following, this assembly operation will be explained with reference to the first connector12as a representative example.

FIG.6is a schematic diagram showing how the housing body is installed to a jig in the assembly operation of the first connector.FIG.7is plan view of the jig shown inFIG.6which is viewed from an installation side on which the housing body is installed and which is shown next to plan view of the housing body similar to that ofFIG.4.

As shown inFIG.6andFIG.7, a jig G11used in the assembly operation of the first connector12is a plate member including an insertion hole G111having an oval shape through which the fitting side of the housing body122is inserted. Further, the jig G11includes a seat portion G112which is a periphery of the insertion hole G111that is raised in the same shape as the shape of the shell flange152of the first shield shell15in plan view from the fitting side. The seat portion G112includes mounting holes G113disposed at positions corresponding to the through holes152bfor screw fixing of the shell flange152.

In the assembly operation of the first connector12, firstly, the housing body122is installed to the jig G11by inserting the fitting side of the housing body122into the insertion hole G111. The seat portion G112of the jig G11is provided with five protrusions G114standing at a position corresponding to the first flange123. As shown inFIG.7, these five protrusions G114are formed such that the respective protrusions G114fit into the five spaces defined by the four rib walls123cof the first flanges123. The housing body122is installed to the jig G11such that the five protrusions G114are fitted into the above-described five spaces of the first flange123, and the second flange124is placed on the opposite side of the protrusions G114on the seat portion G112. Then, with respect to the housing body122in this state, the connector terminals121crimped to the respective ends of the three electric wires111are inserted and accommodated. At this time, the electric wire packing126is attached in advance to each electric wire111, and the connector terminals121together with the electric wire packings126are accommodated inside the housing body122. Subsequently, the rear holder127is arranged so as to sandwich the three electric wires111with the first holder127aand the second holder127b, and is accommodated in the opening of the housing body122so as to push the electric wire packings126therein. Further, the first shield shell15to which the end opening portion of the shield braid14is fixed in a tightened manner is attached to the housing body122such that the cable11consisting of three electric wires111are accommodated in the shield braid14. At this time, the first shield shell15is attached in an orientation in which the first flange123is fitted in the first flange recess153and the second flange124is fitted in the second flange recess154.

In this way, the first connector12is assembled. The second connector13is assembled with the similar procedure, thereby providing the completed wire harness1shown inFIG.1. When assembling the second connector13, a dedicated jig, which is provided with three protrusions G114configured to fit into the three spaces defined by the two rib walls133cof the first flange133of the second connector13, is used.

In this embodiment, the first connector12and second connector13are similar connectors in which the shapes of the housing bodies122,132, the configurations of the housing bodies122,132for housing the connector terminals121,131, etc. are similar to each other. This similarity may cause a risk of wrong assembly that a connector different from a connector to be properly mounted could be mounted on one cable end11a.

To avoid such risk, in the wire harness1of the above-described embodiment, the housing bodies122,132of the first connector12and the second connector13are provided with the first flanges123,133having rugged shapes that are different from each other. Further, in this embodiment, in the assembly operation of the first connector12, the dedicated jig G11configured to fit to the rugged shape of the first flange123is used.

Similarly, in the assembly operation of the second connector13, the dedicated jig configured to fit to the rugged shape of the first flange133is used. Consequently, for example during the assembly operation of the first connector12, even when a worker erroneously attempts to install the housing body132of the second connector13, it cannot be installed because the jig G11does not fit to the rugged shape of the first flange133of the second connector13. Thus, according to the wire harness1of this embodiment, with the rugged shapes of the first flanges123,133that differ between the first connector12and the second connector13, an operation can be carried out using the dedicated jig in each assembly operation. By performing such operation based on the rugged shapes of the first flanges123,133, wrong assembly of the connector during manufacture can be prevented.

In this embodiment, the intervals d11, d13of the plurality of rib walls123c,133cof the first flanges123,133differ between the first connector12and the second connector13. According to this configuration, wrong assembly of the connector can be prevented efficiently with a simple structure of the jigs, the jigs for installing the housing bodies122,132being provided with the protrusions that fit to the spaces defined by the rib walls123c,133c.

Further, in this embodiment, the wire harness1includes the shield braid14, the first shield shell15, and the second shield shell16. The shell flanges152,162of the first shield shell15and the second shield shell16are provided with the first flange recesses153,163and the second flange recesses154,164. The first flange recesses153,163are recesses for accommodating the first flanges123,133, and the second flange recesses154,164are recesses for accommodating the second flanges124,134. That is, in this embodiment, the first shield shell15and the second shield shell16to which the shield braid14is mounted are provided with the shell flanges152,162corresponding to the flanges of the respective connectors. By using the first shield shell15and the second shield shell16as described, the shield braid14can be mounted so as to effectively avoid the flanges intended for preventing the wrong assembly, thereby providing the wire harness1suitable for the transmission of high-frequency electrical signals.

Further, in this embodiment, the first connector12and second connector13include the first flanges123,133and the second flanges124,134having widths different from each other. Also, the respective shell flanges152,162include the first flange recesses153,163and the second flange recesses154,164to which the first flanges123,133and the second flanges124,134fit in a one-to-one manner. According to this configuration, the mounting orientation of the first shield shell15and the second shield shell16with respect to the first connector12and second connector13are uniquely determined to be the orientation in which the two flanges fit into the two flange recesses.

That is, the above configuration can prevent wrong assembly also for the mounting orientation of the first shield shell15and the second shield shell16with respect to the first connector12and second connector13.

Further, in this embodiment, both of the first widths W11, W13of the first flanges123,133and the second widths W12, W14of the second flanges124,134differ between the first connector12and the second connector13. According to this configuration, wrong assembly can be effectively prevented for the installation of the first shield shell15and second shield shell16with respect to the housing bodies122and132.

The embodiments described above only illustrate representative embodiments, and the wire harness is not limited to the embodiments described above. In other words, various modifications can be made without departing from its gist. As long as such modification includes the configuration of the wire harness, they are within its scope.

For example, in the above-described embodiment, the wire harness1in which the first connector12and the second connector13are mounted on the two cable ends11aof one cable11having no branches is shown as one example of the wire harness.

However, the wire harness is not limited thereto; the wire harness may be branched so as to have three or more cable ends and a connector is mounted to each cable end.

Further, in the above-described embodiment, the wire harness1including the cable11formed by bundling the three electric wires111together is shown as one example of the wire harness. However, the wire harness is not limited thereto; the wire harness may include a cable formed by bundling two electric wires together or a cable formed by bundling four or more electric wires together.

Further, in the above-described embodiment, the following shapes are shown as one example of the rugged shapes of the flanges. First, for the first flanges123,133, the plurality of rib walls123c,133cis standing inside the peripheral wall portions123b,133band from the rectangular plate portions123a,133aat the intervals d11, d13. Further, for the second flanges124,134, the plurality of rib walls124c,134cis standing inside the peripheral wall portions124b,134band from the rectangular plate portions124a,134aat the intervals d12, d14. However, the rugged shapes of the flanges are not limited thereto; the rugged shapes may be other than the arrangement of the rib walls, such as corrugations or dispersed arrangement of plurality of recesses, etc., as long as the shapes are different between the plurality of connectors of the wire harness. However, the rugged shapes constituted of the arrangement of the rib walls123c,124c,133c,134ccan effectively prevent the wrong assembly of the connectors by using the simple jig structure of the jigs for installing the housing bodies122,132, as described above.

Further, the above-described embodiment shows, one example of the wire harness, the wire harness1adapted for high-frequency transmission that includes the shield braid14, the first shield shell15and the second shield shell16. The shell flanges152,162of the first shield shell15and the second shield shell16are provided with the first flange recesses153,163and the second flange recesses154,164. However, the wire harness is not limited thereto; it may be the one without the shield braid and such, e.g., a wire harness for power supply. However, according to the fixing structure of the shield braid14in the shield shell including the flange recesses, it is possible to provide the wire harness1for high-frequency transmission while effectively avoiding the flanges for the prevention of the wrong assembly, as described above. In the case of the wire harness for high-frequency transmission, the electric wire may be a shielded wire in which a shield braid is arranged within a sheath, eliminating the need for the shield braid arranged outside of the electric wire bundle.

Further, the above-described embodiment shows, as examples of the flanges, the first flange123,133and the second flange124,134which are disposed at the same position with respect to the axial direction D11, D12and at the two distant positions with respect to the circumferential direction D13, D14and which have different widths from each other. Further, as examples of the flange recesses there are shown the first flange recess153,163and the second flange recess154,164to which the first flange123,133and the second flange124,134fit one-to-one. However, the flanges and the flange recesses are not limited thereto; for example, only one flange may be provided on the outer circumferential surface of the housing, and only one flange recess may be provided on the shell flange of the shield shell. However, by providing the two flanges having different widths and the two flange recesses into which these flanges fit one-to-one, it is possible to prevent the wrong assembly also with respect to the mounting orientation of the first shield shell15and the second shield shell16, as described above. In the case where the plurality of flanges and the plurality of flange recesses are provided, the number thereof is not limited to two, and three or more flanges may be provided on the outer circumferential surface of the housing and the three or more flange recesses may be provided on the shell flange of the shield shell such that the flanges fit one-to-one into these flange recesses.

Further, the above-described embodiment shows, as one example of the wire harness, the wire harness1in which both of the first flange123,133and the second flange124,134have the width in the circumferential direction D14that differ between the first connector12and the second connector13. However, the wire harness is not limited thereto; the width of the flanges may be the same between the plurality of connectors. However, by making the widths of the first flange123,133and the second flange124,134different between the first connector12and the second connector13, it is possible to effectively prevent the wrong assembly of the first shield shell15and the second shield shell16, as described above. In addition, not all of the plurality of flanges provided on the housing need to have width different between the connectors, at least one flange may have width different between the connectors.
