[0011] 1 is mounted on a vehicle such as an automobile, and electrically connects an electrical device of the vehicle to other electrical devices of the vehicle. As shown in FIG. 2, the wire harness 100 according to the embodiment includes a connector 10 and a flat wiring material 20.

[0012] The connector 10 is fitted to a mating connector (not shown). For example, the mating connector is disposed in the housing of a device such as a display or meter device. The wire harness 100 connects, for example, a device having the mating connector to a control device that controls the device. The flat wiring material 20 has a printed circuit including a power line and a signal line.

[0013] The connector 10 includes a terminal 11, a terminal holder 12, a housing 13, a lever 14, and a cover 15.

[0014] 2, terminal 11 is a metal press-fit terminal. Terminal 11 includes a rectangular cylindrical electrical connection portion 11a provided at one axial end of terminal 11, a press-fit portion 11b provided at the other axial end of terminal 11, and a flat, wide portion 11c connecting electrical connection portion 11a and press-fit portion 11b. Terminal 11 is formed in a linear shape, with electrical connection portion 11a, press-fit portion 11b, and wide portion 11c continuing along the axial direction, which is the direction in which terminal 11 is pressed into a through-hole SH (described later).

[0015] The press-fit portion 11b has a central hole that penetrates the press-fit portion 11b in a direction perpendicular to the axial direction. When viewed from the direction in which the central hole penetrates the press-fit portion 11b, the central hole is formed in a rectangular shape that is horizontally elongated in the axial direction. The press-fit portion 11b has a pair of press-fit deformation portions that are arranged to sandwich the central hole, and when the press-fit portion 11b is press-fitted into the through-hole SH, the pair of press-fit deformation portions are formed to be deformable so as to bend toward the central hole by receiving force from the outer periphery of the through-hole SH. In the terminal 11, the portion where the pair of press-fit deformation portions are provided becomes the press-contact portion that is press-contacted with the through-hole SH.

[0016] As shown in FIG. 1 , the terminal holding portion 12 is a member that accommodates the terminals 11 and is molded from an insulating material such as resin. In the embodiment, a plurality of terminal accommodating holes 12a are formed in one of the side surfaces 12s of the terminal holding portion 12. The terminal accommodating holes 12a penetrate the terminal holding portion 12 in the mating direction of the connector 10 with the mating connector. In the terminal holding portion 12 of the embodiment, the plurality of terminal accommodating holes 12a are formed in a plurality of rows, and the plurality of terminal accommodating holes 12a in one adjacent row are formed so as to be shifted in the row direction of the plurality of terminal accommodating holes 12a relative to the plurality of terminal accommodating holes 12a in the other adjacent row. In other words, the plurality of terminal accommodating holes 12a are arranged in a staggered pattern.

[0017] The terminal holding portion 12 accommodates each terminal 11 in a one-to-one relationship in the terminal accommodating hole 12a, with the press-fit portion 11b protruding from the terminal accommodating hole 12a. That is, the terminal holding portion 12 holds the multiple terminals 11 arranged in multiple rows with the press-fit portion 11b protruding. In the embodiment, the terminal holding portion 12 holds the multiple terminals 11 in one adjacent row such that the multiple terminals 11 are shifted in the row direction of the multiple terminals 11 relative to the multiple terminals 11 in the other adjacent row. That is, the multiple terminals 11 are arranged in a staggered pattern by being inserted into the corresponding terminal accommodating holes 12a in the terminal holding portion 12.

[0018] In the embodiment, the terminal holding portion 12 includes a plurality of flat plate portions 12A and 12B. The terminal holding portion 12 in the embodiment is configured by alternately stacking two flat plate portions 12A and two flat plate portions 12B in the thickness direction of the flat plate portions 12A and 12B. On the side surface of each of the flat plate portions 12A and 12B, a plurality of terminal accommodating holes 12a are arranged in a row in a direction perpendicular to the protruding direction in which the press-fit portion 11b protrudes from the terminal holding portion 12.

[0019] In the following description, the row direction in which the terminals 11 are arranged in a row on each flat plate portion 12A, 12B of the terminal holding portion 12 is referred to as the "first direction X." The protruding direction in which the press-fit portion 11b of the terminal 11 protrudes from the terminal holding portion 12 is referred to as the "second direction Y." The stacking direction in which the flat plate portions 12A, 12B of the terminal holding portion 12 are stacked is referred to as the "third direction Z." In the embodiment, the first direction X, the second direction Y, and the third direction Z are perpendicular to one another. The first direction X corresponds to the width direction of the connector 10. The second direction Y corresponds to the mating direction of the connector 10 and the mating connector. The third direction Z corresponds to the height direction of the connector 10.

[0020] The terminal holding portion 12 of the embodiment is formed such that when the flat plate portions 12A and 12B are stacked so that the forming surfaces of the terminal accommodating holes 12a (the surfaces from which the press-fit portions 11b of the terminals 11 protrude) face the same direction, the terminal accommodating holes 12a of the flat plate portions 12A and the terminal accommodating holes 12a of the flat plate portions 12B are arranged in a staggered pattern on the end surfaces (the surfaces on which the terminal accommodating holes 12a are formed) of the terminal holding portion 12. In other words, when the flat plate portions 12A and 12B are stacked so that the forming surfaces of the terminal accommodating holes 12a face the same direction, the positions of the multiple terminal accommodating holes 12a of the flat plate portion 12A are shifted in the first direction X with respect to the positions of the multiple terminal accommodating holes 12a of the flat plate portion 12B.

[0021] Furthermore, in the flat plate portion 12A, one side surface in the first direction X is formed with a recessed portion 12c that fits with an uneven surface 13a formed on one side of the inner surface of the housing 13, which will be described later, and the other side surface of the flat plate portion 12A in the first direction X is formed with a protruding portion 12d that fits with an uneven surface 13a formed on the other side of the inner surface of the housing 13, which will be described later. The flat plate portion 12A is held in the housing 13 by the protruding portion 12d and the recessed portion 12c fitting with the uneven surface 13a on the inner surface of the housing 13.

[0022] Furthermore, a support protrusion 12b is formed on the end face of the flat plate portion 12A from which the press-fit portion 11b protrudes. The support protrusion 12b is a portion that is inserted into a through hole (through hole 22a or through hole 22b) of the rigid board portion 22, which will be described later. On the end face of the flat plate portion 12A from which the press-fit portion 11b protrudes, the support protrusion 12b is formed on the other end in the first direction X (the end of the flat plate portion 12A on the convex portion 12d side).

[0023] Furthermore, in the flat plate portion 12B, a convex portion 12d is formed on one side surface in the first direction X. The convex portion 12d is adapted to fit with an uneven surface 13a formed on one side of the inner surface of the housing 13, which will be described later, and a concave portion 12c is formed on the other side surface of the flat plate portion 12B in the first direction X. The concave portion 12c is adapted to fit with an uneven surface 13a formed on the other side of the inner surface of the housing 13, which will be described later. Similar to the flat plate portion 12A, the flat plate portion 12B is held in the housing 13 by the convex portion 12d and the concave portion 12c fitting with the uneven surface 13a on the inner surface of the housing 13.

[0024] In addition, a support protrusion 12b is also formed on the end surface of the flat plate portion 12B from which the press-fit portion 11b protrudes. Like the support protrusion 12b of the flat plate portion 12A, the support protrusion 12b of the flat plate portion 12B is a portion that is inserted into a through hole (through hole 22a or through hole 22b) of the rigid board portion 22, which will be described later. On the end surface of the flat plate portion 12B from which the press-fit portion 11b protrudes, the support protrusion 12b is formed at one end in the first direction X (the end on the recess 12c side of the flat plate portion 12B).

[0025] The housing 13 is a member that accommodates the terminal holding portion 12 and is made of an insulating material such as resin. The housing 13 of this embodiment is formed in a box shape with an opening on the side where the press-fit portion 11b of the terminal 11 protrudes, and has an accommodating portion HS inside that holds the flat portions 12A and 12B that constitute the terminal holding portion 12 in a stacked state. The terminal holding portion 12 (flat portions 12A and 12B) is inserted through an opening 13p of the box-shaped housing 13, and the press-fit portion 11b of the terminal 11 is held in a state where it protrudes from the opening 13p of the housing 13. As shown in FIG. 3 , the surface of the housing 13 opposite the opening 13p of the housing 13 is formed with a plurality of mating terminal insertion holes 13d into which terminals of a mating connector are inserted. The mating terminal insertion holes 13d are formed in the housing 13 at positions corresponding to the positions of the electrical connection portions of the plurality of terminals 11.

[0026] Lever 14 is attached to housing 13 and is a part that mates connector 30 with the housing of a mating connector by a force-boosting mechanism including lever 14. In other words, lever 14 amplifies the force input to lever 14 and transmits it to the mating connector, thereby mating the mating connector with housing 13. Housing 13 has two wall portions disposed at positions that sandwich each of flat plate portions 12A, 12B in accommodating portion HS in the stacking direction of flat plate portions 12A, 12B (third direction Z). Cylindrical shaft portions 13c are formed on the outer surfaces of the two wall portions of housing 13. Shaft portions 13c rotatably support lever 14.

[0027] As shown in FIG. 1, the flat wiring material 20 is a rigid-flexible board including a flexible printed circuit board portion 21 and a rigid board portion 22. The flexible printed circuit board portion 21 is a flexible, flat-plate-shaped circuit body. The rigid board portion 22 is a flat-plate-shaped member having higher rigidity than the flexible printed circuit board portion 21 and connected to one end of the flexible printed circuit board portion 21. Here, the rigid board portion 22 is, for example, a hard printed wiring board. In the embodiment, the flat wiring material 20 is configured as a flat-plate-shaped circuit board as a whole, with one end of the flexible printed circuit board portion 21 and one end of the rigid board portion 22 connected to each other.

[0028] The flexible printed circuit board portion 21 includes a base film and a printed circuit printed on the base film. The printed circuit is a plurality of conductors linearly drawn from the rigid board portion 22 and electrically connected to each terminal 11 connected to the rigid board portion 22.

[0029] A plurality of through holes SH are formed in the rigid board portion 22. Furthermore, the rigid board portion 22 has through holes (22a, 22b) formed at both ends in the first direction X, through which the support protrusions 12b of the above-mentioned flat plate portions 12A, 12B are inserted.

[0030] The plurality of through holes SH of the rigid board portion 22 are formed to correspond one-to-one to the press-fit portions 11b of the plurality of terminals 11 to be connected to the rigid board portion 22. For example, the plurality of through holes SH of the rigid board portion 22 and corresponding conductors in the printed circuit of the flexible printed board portion are connected by straight conductors provided on the rigid board portion 22.

[0031] In the embodiment, the plurality of through holes SH are formed in a staggered pattern in the rigid substrate portion 22, allowing a large number of through holes SH to be densely packed relative to the area of the rigid substrate portion 22. This allows the connector 10 to have multiple poles while preventing the connector 10 from becoming larger. Furthermore, in the rigid substrate portion 22, the terminals 11 at different positions in the third direction Z can be electrically connected to the printed circuit of the flexible printed substrate portion 21 by straight conductor wires. Therefore, when drawing out wiring from the rigid substrate portion 22, the plurality of terminals 11 can be electrically connected to the corresponding conductor wires in the printed circuit of the flexible printed substrate portion 21 by straight conductor wires without having to create a complex circuit.

[0032] Each through hole SH includes a cylindrical electrical connection portion provided on the inner circumferential surface of the opening of the through hole SH. The electrical connection portion is formed as a plating layer, such as copper plating, formed on the inner circumferential surface of the opening of the through hole SH. The electrical connection portion extends from the cylindrical portion toward the circuit portion of the rigid board so as to be physically and electrically connected to the circuit portion. In this embodiment, the electrical connection portion functions as the inner circumferential surface of the through hole SH. Therefore, the entire inner circumferential surface of the multiple through holes SH can be used as a contact point with the terminal 11.

[0033] 4, in the second direction Y, the electrical connection portions 11a of the multiple terminals 11 are held so as to face corresponding mating terminal insertion holes 13d in the housing 13. When the connector 10 is mated with a mating connector, the mating terminals of the mating connector are inserted into the cylindrical electrical connection portions 11a of the terminals 11 through the mating terminal insertion holes 13d in the housing 13.

[0034] The terminal 11 and the mating terminal are electrically connected by inserting a mating terminal into the electrical connection portion 11a of the terminal 11. Furthermore, as shown in Figures 4 and 5, the press-fit portions 11b of the terminals 11 are press-fit into the corresponding through holes SH, respectively. The press-fit portions 11b are held in a position where they contact the inner circumferential surfaces of the through holes SH, and are electrically connected to the inner circumferential surfaces (electrical connection portions) of the through holes SH.

[0035] The wire harness 100 according to the embodiment includes a pair of flat wiring materials 20 (a first flat wiring material 20A and a second flat wiring material 20B). The first flat wiring material 20A and the second flat wiring material 20B are provided as wiring boards independent of each other.

[0036] The first flat wiring material 20A includes a first flexible printed circuit board portion 21A and a first rigid circuit board portion 22A. The first flexible printed circuit board portion 21A is a flexible, flat-plate-shaped circuit body. The first rigid circuit board portion 22A is a flat-plate-shaped member that has higher rigidity than the first flexible printed circuit board portion 21A and is connected to one end of the first flexible printed circuit board portion 21A. The first flat wiring material 20A is configured as a flat-plate-shaped circuit board as a whole, with one end of the first flexible printed circuit board portion 21A and one end of the first rigid circuit board portion 22A connected.

[0037] The first flexible printed circuit board portion 21A includes a base film and a printed circuit printed on the base film. The printed circuit is a plurality of conductors linearly drawn from the first rigid board portion 22A and is electrically connected to each terminal 11 connected to the first rigid board portion 22A. A plurality of first through holes SH1 are formed in the first rigid board portion 22A. The plurality of first through holes SH1 are formed to correspond one-to-one to the press-fit portions 11b of the plurality of terminals 11 connected to the first rigid board portion 22A.

[0038] The second flat wiring material 20B includes a second flexible printed circuit board portion 21B and a second rigid circuit board portion 22B. The second flexible printed circuit board portion 21B is a flexible, flat-plate-shaped circuit body. The second rigid circuit board portion 22B is a flat-plate-shaped member that has higher rigidity than the second flexible printed circuit board portion 21B and is connected to one end of the second flexible printed circuit board portion 21B. The second flat wiring material 20B is configured as a flat-plate-shaped circuit board overall, with one end of the second flexible printed circuit board portion 21B and one end of the second rigid circuit board portion 22B connected to each other.

[0039] The second flexible printed circuit board portion 21B includes a base film and a printed circuit printed on the base film. The printed circuit is a plurality of conductors linearly drawn from the second rigid board portion 22B and is electrically connected to each terminal 11 connected to the second rigid board portion 22B. A plurality of second through holes SH2 are formed in the second rigid board portion 22B. The plurality of second through holes SH2 are formed to correspond one-to-one to the press-fit portions 11b of the plurality of terminals 11 connected to the second rigid board portion 22B.

[0040] The multiple terminals 11 held by the terminal holding portion 12 constitute a first terminal group arranged on a first side in the third direction Z and a second terminal group arranged on a second side opposite the first side in the third direction Z. In the embodiment, the terminals 11 are arranged in four rows in the third direction Z. The first terminal group includes two rows of terminals 11 on the first side among the rows of terminals 11 arranged in the third direction Z. The second terminal group includes two rows of terminals 11 on the second side among the rows of terminals 11 arranged in the third direction Z.

[0041] The press-fit portions 11b of the corresponding terminals 11 in the first terminal group are press-fitted into the plurality of first through-holes SH1 in the first rigid substrate portion 22A, and the press-fit portions 11b of the corresponding terminals 11 in the second terminal group are press-fitted into the plurality of second through-holes SH2 in the second rigid substrate portion 22B. At this time, the first rigid substrate portion 22A and the second rigid substrate portion 22B are arranged adjacent to each other in the third direction. The first flexible printed substrate portion 21A is connected to one end of the first side of the first rigid substrate portion 22A and extends from the first rigid substrate portion 22A toward the first side. The second flexible printed substrate portion 21B is connected to one end of the second side of the second rigid substrate portion 22B and extends from the second rigid substrate portion 22B toward the second side.

[0042] That is, in the embodiment, two flat wiring materials 20 (a first flat wiring material 20A and a second flat wiring material 20B) are arranged adjacent to each other in the third direction Z, and in each flat wiring material 20, the flexible printed circuit board portion 21 extends toward the opposite side from the adjacent flat wiring material 20.

[0043] The cover 15 is a member that covers the joints between the rigid board portion 22 and the terminals 11 while holding the flexible printed board portion 21, and engages with the housing 13. The housing 13 has engaging protrusions 13b on each of its outer surfaces in the first direction X. The cover 15 has engaging recesses that engage with the engaging protrusions 13b, and is assembled to the housing 13 by engaging the engaging recesses with the engaging protrusions 13b of the housing 13.

[0044] In the embodiment, the cover 15 includes a main body portion, a holding portion, and a hinge. The main body portion of the cover 15 is a portion that covers the joint between the rigid board portion 22 and the terminal 11. The holding portion is disposed on the opposite side of the cover 15 from the joint side, and is connected to the main body portion via a hinge. The holding portion is a portion that holds the flexible printed board portion 21 by sandwiching it between itself and the main body portion. In the embodiment, the first flexible printed board portion 21A is folded back so as to be wrapped around the main body portion of the cover 15, and is sandwiched and held between the holding portion and the main body portion in a state where it is overlapped with the second flexible printed board portion 21B (see FIG. 10).

[0045] Next, a method for manufacturing the wire harness according to the embodiment will be described with reference to Fig. 6 to Fig. 10. The method for manufacturing the wire harness 100 according to the embodiment includes a terminal holding step, a housing accommodating step, a press-fitting step, a cover attaching step, and a lever attaching step.

[0046] As shown in Fig. 6, in the terminal holding step, the terminals 11 are inserted into the corresponding terminal accommodating holes 12a of the terminal holding portion 12. Here, in the housing accommodating step described later, each terminal 11 is inserted so that the press-fit portion 11b of the terminal 11 protrudes from the end face exposed from the opening 13p of the housing 13. The terminals 11 held by the terminal holding portion 12 are arranged on the side surface 12s of the terminal holding portion 12 so that the tip positions of the press-fit portions 11b of the multiple terminals 11 are positioned on the same plane. In other words, the press-fit portions 11b of the multiple terminals 11 held by the terminal holding portion 12 are arranged with the same protruding length from the side surface of the terminal holding portion 12.

[0047] 7, in a housing accommodating step, the terminal holding portion 12 holding the terminal 11 is accommodated in the housing 13. In the embodiment, the flat plate portions 12A and 12B are inserted into the accommodating portion HS of the housing 13 through the opening 13p of the housing 13 in a stacked state, thereby holding each of the flat plate portions 12A and 12B in the housing 13. At this time, the stacked flat plate portions 12A and 12B are inserted so that the recessed portions 12c and the protruding portions 12d of each of the flat plate portions 12A and 12B fit into the uneven surface 13a of the housing 13.

[0048] Thereafter, as shown in FIG. 8, in the press-fitting step, the press-fit portions 11b of the corresponding terminals 11 are press-fitted into the corresponding through holes SH formed in the rigid board portion 22 of the flat wiring material 20.

[0049] In the press-fitting process of the embodiment, two flat wiring materials 20 (a first flat wiring material 20A and a second flat wiring material 20B) are arranged adjacent to each other in the third direction Z, and the press-fit portions 11b of the corresponding terminals 11 are press-fitted into the corresponding through holes SH. That is, the press-fit portions 11b of the corresponding terminals 11 are press-fitted into the corresponding first through holes SH1 of the first rigid substrate portion 22A arranged on a first side in the third direction Z, and the press-fit portions 11b of the corresponding terminals 11 are press-fitted into the corresponding second through holes SH2 of the second rigid substrate portion 22B arranged on a second side opposite the first side in the third direction Z.

[0050] At this time, through hole 22a formed at one end of first rigid substrate portion 22A in the first direction X is inserted into support protrusion 12b formed at one end of flat plate portion 12A in the first direction X, and through hole 22a formed at the other end of first rigid substrate portion 22A in the first direction X is inserted into support protrusion 12b formed at the other end of flat plate portion 12B in the first direction X. Also, through hole 22b formed at one end of second rigid substrate portion 22B in the first direction X is inserted into support protrusion 12b formed at one end of flat plate portion 12A in the first direction X, and through hole 22b formed at the other end of second rigid substrate portion 22B in the first direction X is inserted into support protrusion 12b formed at the other end of flat plate portion 12B in the first direction X.

[0051] In addition, in the press-fitting process of the embodiment, the first flexible printed circuit board portion 21A of the first flat wiring material 20A is arranged to extend from the first rigid board portion 22A toward the first side, and the second flexible printed circuit board portion 21B of the second flat wiring material 20B is arranged to extend from the second rigid board portion 22B toward the second side. In the embodiment, the press-fitting process is performed with the first rigid board portion 22A and the second rigid board portion 22B adjacent to each other, so that the terminals 11 can be press-fitted into the two rigid board portions 22 in a single process.

[0052] 9, in the cover attachment process, the cover 15 is attached to the housing 13 by engaging with it. As described above, in the embodiment, the cover 15 has a main body portion, two holding portions, and a hinge. The two holding portions are adjacent to each other in the third direction Z and are connected to the main body portion via the hinges. The holding portions are engaged with the main body portion so as to cover the main body portion by bending the hinges. In the cover attachment process, the main body portion is attached to cover the two rigid board portions 22, and then the first flexible printed circuit board portion 21A is folded back so as to be wrapped around the main body portion of the cover 15. The folded back first flexible printed circuit board portion 21A is sandwiched between the two holding portions and the main body portion, and the first flexible printed circuit board portion 21A and the second flexible printed circuit board portion 21B are held in an overlapping state.

[0053] 10, in a lever attachment step, the lever 14 is attached to the housing 13. The lever 14 is rotatably attached to the shaft portion 13c of the housing 13. Through the above steps, the wire harness 100 according to the embodiment is manufactured.

[0054] In the above embodiment, the terminal holding portion 12 has a plurality of terminal accommodating holes 12a arranged in a staggered pattern, but the present invention is not limited to this configuration. For example, the terminal accommodating holes 12a may be arranged in a matrix pattern in the terminal holding portion 12.

[0055] In addition, in the above-described embodiment, the terminal holding portion 12 and the housing 13 are separate bodies, but this is not limiting. For example, the terminal holding portion 12 may be formed integrally with the housing 13.

[0056] Furthermore, in the above-described embodiment, the first flexible printed circuit board portion 21A is folded back so as to be wrapped around the main body portion of cover 15, and sandwiched between the holding portion and the main body portion to hold first flexible printed circuit board portion 21A and second flexible printed circuit board portion 21B in an overlapping state, but this is not limiting. For example, cover 15 may be folded back so that first flexible printed circuit board portion 21A and second flexible printed circuit board portion 21B are each wrapped around the main body portion, and first flexible printed circuit board portion 21A and second flexible printed circuit board portion 21B may be pulled out from between the two holding portions in an overlapping state and sandwiched and held between the holding portion and the main body portion.

[0057] Furthermore, the number of flat plate portions 12A, 12B constituting the terminal holding portion 12 is not limited to four. For example, the terminal holding portion 12 may be configured by stacking two flat plate portions 12A, 12B.

[0058] Furthermore, the connector 10 does not necessarily have to have the lever 14 .

[0059] As described above, the wire harness 100 according to the embodiment comprises: a connector 10 including a plurality of terminals 11 each having a press-fit portion 11b and a terminal holding portion 12 that holds the plurality of terminals 11 arranged in at least one row with the press-fit portion 11b protruding; and a first flat wiring material 20A including: a flexible, flat-plate-shaped first flexible printed circuit board portion 21A; and a flat-plate-shaped first rigid board portion 22A connected to one end of the first flexible printed circuit board portion 21A, having higher rigidity than the first flexible printed circuit board portion 21A, having a plurality of first through holes SH1 formed therein, and having the press-fit portions 11b of the corresponding terminals 11 pressed into each of the plurality of first through holes SH1.

[0060] In the wire harness 100 according to the embodiment, the press-fit portion 11b of the terminal 11 is press-fitted into the first rigid board portion 22A of the first flat wiring material 20A, so that the first rigid board portion 22A and the terminal 11 can be electrically connected without using solder. This configuration makes it possible to reduce, for example, the amount of carbon dioxide emitted during the manufacture of the wire harness 100. Furthermore, since the first rigid board portion 22A and the terminal 11 can be electrically connected without using solder, the wire harness 100 can be easily disassembled. Therefore, for example, the wire harness 100 can be easily recycled.

[0061] Furthermore, in the wire harness 100 according to the embodiment, the terminal holding portion 12 arranges the multiple terminals 11 in multiple rows, and holds the multiple terminals 11 in one adjacent row by shifting them in the row direction of the multiple terminals 11 relative to the multiple terminals 11 in the other adjacent row.

[0062] In the wire harness 100 according to the embodiment, the terminals 11 in one adjacent row are arranged offset relative to the terminals 11 in the other adjacent row in the row direction of the terminals 11, thereby enabling the metal foil portion of the first flexible printed circuit board portion 21A to be drawn out linearly. This configuration simplifies the circuit layout of one flexible printed circuit board portion. Furthermore, the number of terminals 11 connected to one rigid board portion can be increased, allowing the connector 10 to have multiple poles while preventing the connector 10 from becoming larger.

[0063] Moreover, the wire harness 100 according to the embodiment further includes a second flat wiring material 20B including a second flexible printed circuit board portion 21B having a flexible, flat plate shape, and a second rigid board portion 22B connected to one end of the first flexible printed circuit board portion 21A, having higher rigidity than the second flexible printed circuit board portion 21B, and having a plurality of second through holes SH2 formed therein. The plurality of terminals 11 are arranged in a first terminal group arranged on a first side in a direction intersecting the row direction of the plurality of terminals 11, and a second terminal group arranged on a second side in a direction intersecting the row direction of the plurality of terminals 11. and a second terminal group arranged on a second side opposite to the one side, wherein the press-fit portion 11b of a corresponding terminal 11 in the first terminal group is press-fitted into each of the plurality of first through holes SH1, and the press-fit portion 11b of a corresponding terminal 11 in the second terminal group is press-fitted into each of the plurality of second through holes SH2, the first flexible printed circuit board portion 21A extending from the first rigid board portion 22A toward the first side, and the second flexible printed circuit board portion 21B extending from the second rigid board portion 22B toward the second side.

[0064] In the wire harness 100 according to the embodiment, the first flat wiring material 20A and the second flat wiring material 20B are arranged facing each other, so that the terminals 11 can be pressed into the two flat wiring materials 20 in a single process.

[0065] The contents disclosed in the above embodiments can be implemented in appropriate combinations. [Explanation of symbols]
