Title of the invention: Wire harness Technical field

[0001] The present invention relates to a wire harness in which a connector is mounted on a cable end. Technological background

[0002] Conventionally, a wire harness in which a connector is mounted on a cable end is widely used for connection of various electrical and electronic devices (for example, see Patent Document 1). In some of the wire harnesses as described above, the connectors mounted on the plurality of cable ends are similar connectors in which shapes of housing bodies, configurations of the housing bodies for housing connector terminals, etc. are similar to each other. Wire harnesses using such similar connectors have many advantages in manufacturing, such as a common assembly procedure for the connectors during manufacturing. Related art

[0003] Patent Document 1: JP 2019-098978 A Summary of the invention Problem to be solved by the invention

[0004] However, in the wire harness using the similar connectors, this similarity of the connectors may result in poor assembly during the manufacture of the wire harness, for example, a connector that is different from a connector to be properly assembled could be mounted on a cable end.

[0005] The present invention focuses on the problem as described above, and an object of the present invention is to provide a wire harness capable of preventing improper assembly during manufacturing. Solution to the problem

[0006] In order to achieve the above-described object, the present invention provides, in one aspect, a wire harness including a cable consisting of a plurality of electrical wires gathered together so as to include a plurality of cable ends, and a plurality of connectors mounted one-to-one on the plurality of cable ends, wherein each of the plurality of connectors includes a connector terminal connected to one end of the electrical wire, a tubular housing body which accommodates the connector terminal therein, and a flange formed to project from an outer circumferential surface of the housing body, wherein, on a nesting side for interlocking with a mating connector, the flange has a cut-out shape that differs between the plurality of connectors. Advantageous effect of the invention

[0007] According to the above-described wire harness, the respective housing bodies of the plurality of connectors mounted on the plurality of cable ends are provided with the flanges having cut shapes that differ from each other among the plurality of connectors. Thus, even when the plurality of connectors are similar connectors, improper assembly of the connector during manufacturing can be avoided by performing an operation such as performing assembly by installing the housing body on a jig that fits with the cut shape of each flange.

[0053] According to this embodiment, the first connector 12 illustrated in the exploded perspective view of [Fig. 3] and the second connector 13 illustrated in the exploded perspective view of [Fig. 4] are both assembled by installing the housing bodies 122, 132 on jigs described below. This assembly operation is substantially the same between the first connector 12 and the second connector 13. In the following, this assembly operation will be explained with reference to the first connector 12 as a representative example.

[0054] [Fig. 6] is a schematic diagram showing how the housing body is installed on a jig during the assembly operation of the first connector. [Fig. 7] is a plan view of the jig illustrated in [Fig. 6] which is viewed from an installation side on which the housing body is installed and which is illustrated alongside a plan view of the housing body similar to that of [Fig. 4].

[0055] As illustrated in [Fig. 6] and [Fig. 7], a jig G11 used in the assembly operation of the first connector 12 is a plate member including an insertion hole GUI having an oval shape through which the mating side of the housing body 122 is inserted. Furthermore, the jig G11 includes a seat portion G112 which is a periphery of the insertion hole GUI that is raised in the same shape as the shape of the shell flange 152 of the first shield shell 15 in a plan view from the mating side. The seat portion G112 includes mounting holes G113 provided at positions corresponding to the through holes 152b for screw fixing of the shell flange 152.

[0056] In the assembly operation of the first connector 12, firstly, the housing body 122 is installed on the jig G11 by inserting the nesting side of the housing body 122 into the insertion hole G111. The seat portion G112 of the jig G11 is provided with five projections G114 standing at a position corresponding to the first flange 123. As illustrated in [Fig. 7], these five projections G114 are formed such that the respective projections G114 fit into the five spaces defined by the four rib walls 123c of the first flanges 123. The housing body 122 is installed on the jig G11 such that the five projections G114 fit into the above-described five spaces of the first flange 123, and the second flange 124 is placed on the opposite side of the projections G114 on the seat portion G112.Then, with respect to the housing body 122 in this state, the connector terminals 121 crimped on the respective ends of the three electric wires 111 are inserted and received. At this time, the electric wire fitting 126 is attached in advance to each electric wire 111, and the connector terminals 121 with the electric wire fittings 126 are received inside the housing body 122. Then, the rear holder 127 is arranged so as to sandwich the three electric wires 111 with the first holder 127a and the second holder 127b, and is received in the opening of the housing body 122 so as to push the electric wire fittings 126 therein.Further, the first shielding jacket 15 to which the end opening portion of the shielding braid 14 is sealed is attached to the housing body 122 such that the cable 11 consisting of three electric wires 111 is accommodated in the shielding braid 14. At this time, the first shielding jacket 15. shield 15 is attached in an orientation in which the first flange 123 is nested in the first flange recess 153 and the second flange 124 is nested in the second flange recess 154.

[0057] In this way, the first connector 12 is assembled. The second connector 13 is assembled with the similar procedure, thus providing the completed wire harness 1 shown in [Fig. 1]. When assembling the second connector 13, a dedicated jig, which is provided with three protrusions G114 configured to fit into the three spaces defined by the two rib walls 133c of the first flange 133 of the second connector 13, is used.

[0058] According to this embodiment, the first connector 12 and the second connector 13 are similar connectors in which the shapes of the housing bodies 122, 132, the configurations of the housing bodies 122, 132 for housing the connector terminals 121, 131, etc. are similar to each other. This similarity may result in a risk of incorrect assembly because a connector different from a connector to be correctly mounted could be mounted on a cable end 11a.

[0059] In order to avoid such a risk, in the wire harness 1 of the embodiment described above, the housing bodies 122, 132 of the first connector 12 and the second connector 13 are provided with the first flanges 123, 133 having cut shapes that are different from each other. Furthermore, according to this embodiment, during the assembly operation of the first connector 12, the dedicated jig G11 configured to fit onto the cut shape of the first flange 123 is used. Similarly, during the assembly operation of the second connector 13, the dedicated jig configured to fit onto the cut shape of the first flange 133 is used.Accordingly, for example during the assembly operation of the first connector 12, even when a worker mistakenly attempts to install the housing body 132 of the second connector 13, it cannot be installed because the jig G11 does not fit over the cut-out shape of the first flange 133 of the second connector 13. Thus, according to the wire harness 1 of this embodiment, with the cut-out shapes of the first flanges 123, 133 differing between the first connector 12 and the second connector 13, an operation can be performed using the dedicated jig during each assembly operation. By performing such an operation based on the cut-out shapes of the first flanges 123, 133, improper assembly of the connector during manufacturing can be prevented.

[0060] According to this embodiment, the intervals dl 1, dl 3 of the plurality of rib walls 123c, 133c of the first flanges 123, 133 differ between the first connector 12 and the second connector 13. According to this configuration, poor assembly of the connector can be effectively avoided with a simple structure of the jigs, the templates for installing the housing bodies 122, 132 being provided with the projections which fit over the spaces defined by the rib walls 123c, 133c.

[0061] Furthermore, according to this embodiment, the wire harness 1 includes the shield braid 14, the first shield jacket 15 and the second shield jacket 16. The jacket flanges 152, 162 of the first shield jacket 15 and the second shield jacket 16 are provided with the first flange recesses 153, 163 and the second flange recesses 154, 164. The first flange recesses 153, 163 are recesses for receiving the first flanges 123, 133, and the second flange recesses 154, 164 are recesses for receiving the second flanges 124, 134. That is, according to this embodiment, the first shield jacket 15 and the second shield jacket 16 on which the shield braid is mounted are provided. shielding 14 are provided with the casing flanges 152, 162 corresponding to the flanges of the respective connectors.By using the first shielding jacket 15 and the second shielding jacket 16 as described, the shielding braid 14 can be mounted so as to effectively avoid the flanges intended to prevent misassembly, thereby providing the wire harness 1 intended for the transmission of high-frequency electrical signals.

[0062] Further, according to this embodiment, the first connector 12 and the second connector 13 include the first flanges 123, 133 and the second flanges 124, 134 having different widths from each other. In addition, the respective shell flanges 152, 162 include the first flange recesses 153, 163 and the second flange recesses 154, 164 onto which the first flanges 123, 133 and the second flanges 124, 134 fit in a one-to-one manner. According to this configuration, the mounting orientation of the first shield shell 15 and the second shield shell 16 relative to the first connector 12 and the second connector 13 is determined uniquely to be the orientation in which both flanges fit into both flange recesses.That is, the above configuration can avoid poor assembly also for the mounting orientation of the first shielding jacket 15 and the second shielding jacket 16 relative to the first connector 12 and the second connector 13.

[0063] Furthermore, according to this embodiment, the first widths W11, W13 of the first flanges and the second widths W12, W14 of the second flanges 124, 134 differ between the first connector 12 and the second connector 13. According to this configuration, poor assembly can be effectively avoided for the installation of the first shielding jacket 15 and the second shielding jacket 16 with respect to the housing bodies 122 and 132.

[0064] The embodiments described above illustrate only 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 meaning. As long as such a modification includes the configuration of the wire harness, it falls within its scope.

[0065] For example, in the embodiment described above, the wire harness 1 in which the first connector 12 and the second connector 13 are mounted on both cable ends 11a of a cable 11 having no branching is shown as an 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 on each cable end.

[0066] Furthermore, in the embodiment described above, the wire harness 1 including the cable 11 formed by gathering the three electric wires 111 is illustrated as an example of the wire harness. However, the wire harness is not limited thereto; the wire harness may include a cable formed by gathering two electric wires or a cable formed by gathering four or more electric wires.

[0067] Furthermore, in the embodiment described above, the following shapes are illustrated as an example of the cut shapes of the flanges. First, for the first flanges 123, 133, the plurality of rib walls 123c, 133c stand up inside the peripheral wall portions 123b, 133b and from the rectangular plate portions 123a, 133a at the intervals d11, d13. Further, for the second flanges 124, 134, the plurality of rib walls 124c, 134c stand up inside the peripheral wall portions 124b, 134b and from the rectangular plate portions 124a, 134a at the intervals d12, d14. However, the cut shapes of the flanges are not limited thereto; the cut shapes may be other than the arrangement of the rib walls, such as corrugations or scattered arrangement of a plurality of recesses, etc., as long as the shapes are different among the plurality of connectors of the wire harness.However, the cut shapes made of the arrangement of the rib walls 123c, 124c, 133c, 134c can effectively prevent the poor assembly of the connectors by using the simple jig structure of the jigs for installing the housing bodies 122, 132, as described above.

[0068] Furthermore, the above-described embodiment illustrates an example of the wire harness, the wire harness 1 being suitable for high-frequency transmission which includes the shielding braid 14, the first shielding jacket 15 and the second shielding jacket 16. The jacket flanges 152, 162 of the first shielding jacket 15 and the second shielding jacket 16 are provided with the first flange recesses 153, 163 and the second flange recesses 154, 164. However, the wire harness is not limited to this; it may be the one without the shielding braid and the like, for example, a wire harness for power supply. However, according to the fixing structure of the shielding braid 14 in the shielding jacket including the flange recesses, it is possible to provide the wire harness 1 for high-frequency transmission while effectively avoiding the flanges for the prevention of misassembly, 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 shielded braid is arranged in a sheath, eliminating the need to arrange the shielding braid outside the electric wire harness.

[0069] Furthermore, the above-described embodiment illustrates, as examples of the flanges, the first flange 123, 133 and the second flange 124, 134 which are arranged at the same position with respect to the axial direction D11, D12 and at the two distant positions with respect to the circumferential direction D13, D14 and which have different widths from each other. Furthermore, as examples of the flange recesses, are illustrated the first flange recess 153, 163 and the second flange recess 154, 164 on which the first flange 123, 133 and the second flange 124, 134 fit one-to-one. However, the flanges and the flange recesses are not limited thereto; for example, only one flange may be located on the outer circumferential surface of the housing, and only one flange recess may be located on the jacket flange of the shield jacket.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 avoid the misassembly also with respect to the mounting orientation of the first shielding shell 15 and the second shielding shell 16, 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 shielding shell such that the flanges fit one-to-one into these flange recesses.

[0070] Furthermore, the above-described embodiment illustrates, as an example of the wire harness, the wire harness 1 in which the first flange 123, 133 and the second flange 124, 134 have the width in the circumferential direction D14 that differs between the first connector 12 and the second connector 13. However, the wire harness is not limited to this; the width of the flanges may be the same between the plurality of connectors. However, by making the widths of the first flange 123, 133 and the second flange 124, 134 different between the first connector 12 and the second connector 13, it is possible to effectively prevent the improper assembly of the first shielding jacket 15 and the second shielding jacket 16, as described above.Additionally, not all of the plurality of flanges on the housing need have a different width between the connectors, at least one flange may have a different width between the connectors.
