The terminal holding part 12 (the flat plate parts 12A and 12B) is inserted from an opening 13 pof the box-shaped housing 13, and the terminals 11 are held in a state where the insertion portions protrude from the opening 13 pof the housing 13. The housing 13 has a plurality of mating terminal insertion holes formed in a surface of the housing 13 opposite to the opening 13 pto allow terminals of a connector to be inserted into these holes. In the housing 13, the mating terminal insertion holes are formed at positions corresponding to the positions of the electrical connection portions in the plurality of terminals 11, respectively.The lever 14 is a part fixed to the housing 13 for connecting the housing of the connector 10 to a housing of a mating connector through a reinforcing mechanism including the lever 14. That is, the lever 14 is a part that amplifies a force applied to the lever 14 and fits the housing 13 to a mating connector, the amplified force being transmitted to the mating connector.The housing 13 has two wall portions disposed at positions between which the flat plate parts 12A and 12B are enclosed in the housing space HS in the stacking direction (the third direction Z) of the flat plate parts 12A and 12B. On the outer sides of the two wall sections of the housing 13, a cylindrical shaft part 13 bis formed in each case. The lever 14 is fixed to the shaft portion 13b and rotatably supported.The planar guide element 20 is a rigid-flexible printed circuit board having a flexible printed circuit board part 21 and a rigid printed circuit board part 22.As shown in FIG. 3, the flexible circuit board part 21 is a flat plate-shaped circuit body having flexibility. A plurality of through holes TH are formed in the flexible circuit board part 21. The plurality of through holes TH are formed to correspond to the insertion portions of the plurality of terminals 11 one-to-one. Around each of the plurality of through holes TH, a copper foil portion (land) to which a preliminary solder is applied is formed. The copper foil portion is formed so as to surround the outer periphery of each of the plurality of through holes TH.As illustrated in FIGS. 1 and 2, the flexible circuit board member 21 is disposed so as to cover the end surface 12 sfrom which the insertion portions of the plurality of terminals 11 of the terminal holding member 12 protrude. The flexible circuit board member 21 is physically and electrically connected to the insertion portions of the terminals 11 via solders SD 1 in a state where the insertion portions of the terminals 11 corresponding to the plurality of through holes TH are inserted into the plurality of through holes TH.The rigid circuit board part 22 is a flat plate-shaped member having higher rigidity than the flexible circuit board part 21 and connected to one end of the flexible circuit board part 21. In the embodiment, one end of the flexible circuit board part 21 and one end of the rigid circuit board part 22 are connected to each other, and the planar guide member 20 is formed as a flat plate-shaped circuit board as a whole. The rigid printed circuit board part 22 is here, for example, a hard-wired printed circuit board. Electronic components 30 are physically and electrically connected to the rigid printed circuit board part 22 via soldered joints SD 2.As shown in FIG. 3, the flexible circuit board part 21 includes a base sheet 21 aand a circuit board 21 bprinted on the base sheet 21 a. The printed circuit board 21 bis composed of a plurality of conductive wires linearly drawn out from the rigid circuit board part 22, and is electrically connected to the electronic components 30 mounted on the rigid circuit board part 22.In the embodiment, each of the plurality of conductive wires constituting the printed circuit board 21 bis provided as a linear conductive wire extending along the third direction. Each of the plurality of conductive wires constituting the printed circuit board 21 bis formed to pass through the soldering surface around each of the through holes TH formed in the flexible printed circuit board part 21. In this configuration, the insertion portion of the terminal 11 inserted into the through hole TH is electrically connected to one of the conductive wires passing through the through hole TH via the solder SD 1.In the embodiment, a large number of through holes TH can be densely formed in the base sheet 21a because the plurality of through holes TH are offset in the flexible circuit board part 21. That is, the number of through holes TH per unit area in the base film 21 acan be increased. Therefore, it is possible to suppress enlargement of the connector 10 and at the same time to configure the connector 10 to be multipolar. Moreover, the insertion portions of the terminals 11 disposed at different positions in the third direction Z can be electrically connected to the rigid plate member 22 by connecting the insertion portions of the terminals 11 to different linear conductive wires. Since each of the plurality of terminals 11 and the rigid circuit board part 22 can be electrically connected by the linear conductive wire, it is not necessary to prepare a complicated circuit, thereby facilitating the preparation of the printed circuit board 21 b.In the planar guide member 20 according to the embodiment, the flexible circuit board 21 has a bent portion 23 bent in a direction along the second direction Y on an end side to which the rigid circuit board 22 is connected. The rigid circuit board 22 is disposed to face the terminal holding part 12 in a direction (here, the third direction Z) intersecting the second direction Y when the flexible circuit board 21 is bent at the bent portion 23. That is, in the planar guide member 20 of the embodiment, in a state where the flexible circuit board 21 is bent on an end side to which the rigid circuit board 22 is connected, the flexible circuit board 21 is positioned to face the terminal holding part 12 in the second direction Y, and the rigid circuit board 22 is positioned to face the terminal holding part 12 in a direction (third direction Z) crossing the second direction Y.As illustrated in FIG. 1, the rigid plate part 22 is accommodated together with the terminal holding part 12 in the housing space HS of the housing 13, facing the terminal holding part 12 in a direction (third direction Z) intersecting the protruding direction of the insertion portions with respect to the terminal holding part 12.Next, a method of manufacturing the wire harness 100 according to the embodiment will be described with reference to FIGS. 4 to 8.

At this time, each of the terminals 11 is inserted such that the insertion portion of the terminal 11 protrudes from the end surface 12 sopen from the opening 13 pof the housing 13 in the housing arranging step described below. The terminals 11 held by the terminal holding part 12 are arranged such that the positions of the leading edges of the insertion portions of the plurality of terminals 11 on the end surface 12 sof the terminal holding part 12 are in the same plane. That is, the insertion portions of the plurality of terminals 11 held by the terminal holding part 12 are arranged in a state where their protruding lengths from the end surface 12 sof the terminal holding part 12 are aligned.Thereafter, as illustrated in FIG. 6, in the assembling step S 2, the planar guide member 20 is assembled with the terminal holding part 12 that holds the terminals 11 by inserting the insertion portions of the terminals 11 into the through holes TH of the flexible circuit board part 21 in the planar guide member 20. That is, the flexible circuit board 21 is assembled with the terminal holding part 12 by arranging the flexible circuit board 21 to correspond to the surface of the terminal holding part 12 from which the insertion portions of the terminals 11 protrude in the second direction Y. In the assembling step S 2, solders are preliminarily applied to the planar guide member 20 assembled at connection portions between the insertion portions of the terminals 11 and the flexible circuit board part 21 (land portions around the through holes TH) and at connection portions between the electronic components 30 and the rigid circuit board part 22.Thereafter, in the laser irradiation step S 3, the preliminary solder joints at the connection portions are melted by laser irradiation of the planar guide member 20, and solder joints between the flexible circuit board part 21 and the terminals 11 and solder joints between the rigid circuit board part 22 and the electronic components 30 are collectively performed. In the embodiment, the solder joints of the terminals 11 and the electronic components 30 are collectively performed with the planar guide member 20 by moving the region where the laser L 1 is irradiated at a constant speed along the third direction Z as indicated by an arrow Y 1 in FIG. 6.Thereafter, in the bending step S 4, by bending the flexible circuit board part 21 toward the terminal holding part 12 as shown by an arrow Y 2 in FIG. 7 on an end side where the rigid circuit board part 22 is connected, the rigid circuit board part 22 faces the terminal holding part 12 in a direction (third direction Z) intersecting the protruding direction of the insertion portions with respect to the terminal holding part 12.Subsequently, as illustrated in FIG. 8, in the housing arranging step S 5, the terminal holding part 12 is accommodated in the housing 13 in a state in which the planar guide member 20 is mounted thereon and the terminals 11 are held thereby. In the embodiment, the flat plate parts 12A and 12B are inserted into the housing space HS of the housing 13 from the opening 13 pof the housing 13 in a state in which the flat plate parts 12A and 12B are stacked, whereby the flat plate parts 12A and 12B are held in the housing 13. At this time, the stacked flat plate parts 12A and 12B are inserted so that the convex portions 12 band the concave portions 12 cof the flat plate parts 12A and 12B fit on the uneven surfaces 13 aof the housing 13. Through the above-described steps, the wire harness 100 according to the embodiment is manufactured.In the above-described embodiment, the plurality of terminal accommodating holes 12 aare arranged offset in the terminal holding part 12, but the present invention is not limited to this configuration. For example, the plurality of terminal receiving holes 12 amay be arranged in the terminal holding part 12 in the form of a matrix.Moreover, in the above-described embodiment, the insertion portion of the terminal 11 has a rod shape, but the present invention is not limited thereto. For example, the insertion portion of the terminal 11 may have a tubular shape.Moreover, the number of the flat plate parts 12A and 12B constituting the terminal holding part 12 is not limited to three. For example, the terminal holding part 12 may be configured by stacking two flat plate parts 12A and 12B (i.e., a flat plate part 12A and a flat plate part 12B). Moreover, the terminal holding part 12 may be configured by stacking four or more flat plate parts 12A and 12B.Moreover, in the above-described embodiment, the terminal holding part 12 and the housing 13 are separate bodies, but the present invention is not limited thereto. For example, the terminal holding part 12 may be formed integrally with the housing 13.As described above, a wire harness 100 according to the embodiment includes: a connector 10 including a plurality of terminals 11 having insertion portions; and a terminal holding part 12 that holds the plurality of terminals 11 arranged in a plurality of rows in a state in which the insertion portions protrude therefrom; A planar guide member 20 including a flat plate-shaped flexible printed circuit board member 21 having flexibility in which a plurality of through holes TH are formed to be physically and electrically connected to the terminals 11 through the through holes TH, wherein the flexible printed circuit board member 21 is arranged to cover an end surface 12s from which the insertion portions of the plurality of terminals 11 protrude from the terminal holding member 12 and is physically and electrically connected to the insertion portions via solders in a state in which the insertion portions of the terminals 11 corresponding to the plurality of through holes TH are inserted into the plurality of through holes TH, respectively.In the wire harness 100 according to the embodiment, by arranging the plurality of terminals 11 in a plurality of rows and inserting the insertion portions of the terminals 11 into the through holes TH of the flexible circuit board 21, the solder joints between the terminals 11 and the flexible circuit board 21 can be irradiated with laser together. With this configuration, the solder joints can be made uniform without adjusting the laser power. Therefore, in the wire harness 100 according to the embodiment, the plurality of terminals 11 can be soldered to the flexible circuit board part 21 of the planar guide member 20 as appropriate.Moreover, the planar guide member 20 according to the embodiment includes a flat plate-shaped rigid circuit board part 22 connected to one end of the flexible circuit board part 21 and having higher rigidity than the flexible circuit board part 21, electronic components 30 being physically and electrically connected thereto via solders, and in a state where the flexible circuit board part 21 is bent on one end side, the flexible circuit board part 21 is positioned to be opposed to the terminal holding part 12 in a protruding direction of the insertion portions with respect to the terminal holding part 12, and the rigid circuit board part 22 is positioned to be opposed to the terminal holding part 12 in a direction intersecting the protruding direction.In the wire harness 100 according to the embodiment, the planar guide member 20 includes the flat plate-shaped rigid circuit board part 22 on which electronic components 30 are mounted, and the flexible circuit board part 21 is configured to be bendable in the planar guide member 20. In this configuration, for example, not only solders connecting the flexible circuit board part 21 and the terminals 11 but also solders connecting the rigid circuit board part 22 and the electronic components 30 can be irradiated together with lasers. In the wire harness 100 according to the embodiment, by bending the flexible circuit board 21, the rigid circuit board 22 faces and overlaps the terminal holding part 12 in the direction intersecting the protruding direction of the insertion portions. In this way, the rigid circuit board part 22 can be accommodated in, for example, the housing 13 or the like in a state where the rigid circuit board part 22 overlaps the terminal holding part 12, thereby reducing the size of the wire harness 100. Moreover, in the configuration in which the electronic components 30 are mounted on the rigid circuit board part 22 adjacent to the flexible circuit board part 21, the influence of vibrations caused by a fitting chatter between the connector and a mating connector can be suppressed.In the wire harness 100 according to the embodiment, the terminal holding part 12 includes a plurality of flat plate parts 12A and 12B having a flat plate shape, each holding the plurality of terminals 11 in one of the rows, and the connector 10 further includes a housing 13 holding the plurality of flat plate parts 12A and 12B stacked in a thickness direction of the plurality of flat plate parts 12A and 12B in a state where the end surface 12 sof the terminal holding part 12 is exposed to the outside.In the wire harness 100 according to the embodiment, by stacking a plurality of flat plate parts 12A and 12B, the number of the terminals 11 connected to the planar guide member 20 can be increased, whereby it is possible to suppress enlargement of the connector 10 and to configure the connector 10 to be multipolar.In the wire harness 100 according to the embodiment, the terminal holding part 12 holds the plurality of terminals 11 arranged such that the plurality of terminals 11 in one of the rows adjacent to each other are shifted in a row direction of the plurality of terminals 11 with respect to the plurality of terminals 11 in the other of the rows adjacent to each other.In the wire harness 100 according to the embodiment, by arranging the terminals 11 so that their relative positions are shifted between the rows, an operator can easily check whether the flexible circuit board part 21 and the terminals 11 are connected to each other appropriately by soldering. Moreover, with this configuration, the terminals 11 can be more compact and densely arranged.The contents disclosed in the above-described embodiment may be executed in appropriate combinations.The wire harness according to the present embodiment has an advantage that a plurality of conductive members can be suitably soldered to the planar guide member.References included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
