Furthermore, components in the following embodiments include those that can be easily imagined by a person skilled in the art or those that are substantially the same.

[0010] [Embodiment] An embodiment will be described with reference to Fig. 1 to Fig. 8. The embodiment relates to a wire harness.

[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. 1, 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 according to the embodiment connects, for example, a device having a 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] As shown in FIG. 2, the connector 10 includes a terminal 11, a terminal holder 12, a housing 13, and a lever 14.

[0014] The terminal 11 is a metal terminal fitting. The wire harness 100 according to the embodiment includes a plurality of terminals 11. The terminal 11 includes a rectangular cylindrical electrical connection portion and a rod-shaped insertion portion protruding from one end of the electrical connection portion. The electrical connection portion of the terminal 11 is a portion that is electrically connected to a terminal of a mating connector. The insertion portion of the terminal 11 is a portion that is inserted into a through-hole SH (described later) of the flat wiring material 20.

[0015] The terminal holding portion 12 is a member that houses and holds the terminals 11, and is molded from an insulating material such as resin. In this embodiment, a plurality of terminal accommodating holes 12a are formed in an end surface 12s of the terminal holding portion 12. The terminal accommodating holes 12a penetrate the terminal holding portion 12 in the direction in which the connector 10 is mated with a mating connector.

[0016] In the terminal holder 12 of the embodiment, the terminal accommodating holes 12a are formed in multiple rows, and the terminal accommodating holes 12a in one adjacent row are shifted in the row direction of the terminal accommodating holes 12a relative to the terminal accommodating holes 12a in the other adjacent row. In other words, the terminal accommodating holes 12a are arranged in a staggered pattern.

[0017] The terminal holding portion 12 accommodates each terminal 11 in a terminal accommodating hole 12a in a one-to-one relationship, with at least a portion of a rod-shaped insertion portion protruding from the terminal accommodating hole 12a. With this configuration, the terminal holding portion 12 holds the multiple terminals 11 arranged in multiple rows with the insertion portion 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 offset in the row direction relative to the multiple terminals 11 in the other adjacent row. In other words, the multiple terminals 11 are arranged in a staggered pattern by being inserted into the corresponding terminal accommodating hole 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 of the embodiment is configured by stacking two flat plate portions 12A and one flat plate portion 12B in the thickness direction of the flat plate portions 12A and 12B. In the terminal holding portion 12 of the embodiment, the flat plate portions 12A and 12B are stacked such that one flat plate portion 12B is located between the two flat plate portions 12A. A plurality of terminal accommodating holes 12a (four terminal accommodating holes 12a in this example) are arranged in a row on an end surface 12s of each of the flat plate portions 12A and 12B, respectively, penetrating the flat plate portions 12A and 12B in the mating direction of the connector 10 and the mating connector (the insertion direction of the terminals 11).

[0019] In the following description, the row direction in which the terminals 11 are arranged in a row on each of the flat plate portions 12A, 12B of the terminal holding portion 12 is referred to as the "first direction X." The protruding direction in which the insertion portions of the terminals 11 protrude 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 insertion portions 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 surface 12s 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] One side surface of the flat plate portion 12A in the first direction X is formed with a convex portion 12b 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 concave portion 12c 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. Furthermore, one side surface of the flat plate portion 12B in the first direction X is formed with a concave 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 convex portion 12b 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 portions 12A and 12B are held in the housing 13 by the convex portion 12b and the concave portion 12c fitting with the uneven surface 13a on the inner surface of the housing 13.

[0022] 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 that is open on the side where the insertion portion of the terminal 11 protrudes, and has an accommodating portion HS inside that holds the flat plate portions 12A and 12B that make up the terminal holding portion 12 in a stacked state. The terminal holding portion 12 (flat plate portions 12A and 12B) is inserted through an opening 13p of the box-shaped housing 13 and holds the insertion portion of the terminal 11 in a state where it protrudes from the opening 13p of the housing 13. A plurality of mating terminal insertion holes into which terminals of a mating connector are inserted are formed on the surface of the housing 13 opposite the opening 13p of the housing 13. The mating terminal insertion holes are formed in the housing 13 at positions that correspond to the positions of the electrical connection portions of the plurality of terminals 11.

[0023] Lever 14 is attached to housing 13 and is the part that mates connector 10 with the housing of the mating connector by a force-boosting mechanism that includes 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.

[0024] The housing 13 has two walls arranged at positions sandwiching the flat plate portions 12A, 12B in the stacking direction (third direction Z) of the flat plate portions 12A, 12B within the storage portion HS. A cylindrical shaft portion 13b is formed on each of the outer surfaces of the two walls of the housing 13. The lever 14 is attached to the shaft portion 13b and rotatably supported thereon.

[0025] The flat wiring material 20 is a rigid-flexible board including a flexible printed board portion 21 and a rigid board portion 22 .

[0026] As shown in Fig. 3, the flexible printed circuit board unit 21 is a flexible, flat circuit body. A plurality of through holes SH are formed in the flexible printed circuit board unit 21. The plurality of through holes SH are formed so as to correspond one-to-one to the insertion portions of the plurality of terminals 11. Furthermore, a copper foil portion (land) to which preliminary solder is applied is formed around each of the plurality of through holes SH. The copper foil portion is formed so as to surround the outer periphery of the plurality of through holes SH.

[0027] 1 and 2, the flexible printed circuit board part 21 is arranged to cover an end face 12s from which the insertion portions of the multiple terminals 11 protrude in the terminal holding part 12. With the insertion portions of the corresponding terminals 11 inserted into the multiple through holes SH, the flexible printed circuit board part 21 is physically and electrically connected to the insertion portions via solder SD1.

[0028] The rigid board portion 22 is a flat member having higher rigidity than the flexible printed board portion 21 and connected to one end of the flexible printed board portion 21. In the embodiment, the flat wiring material 20 is configured as a flat circuit board as a whole, with one end of the flexible printed board portion 21 and one end of the rigid board portion 22 connected to each other. Here, the rigid board portion 22 is, for example, a hard printed wiring board. The electronic component 30 is physically and electrically connected to the rigid board portion 22 via solder SD2.

[0029] 3, in the flat wiring material 20, the flexible printed circuit board portion 21 includes a base film 21a and a printed circuit 21b printed on the base film 21a. The printed circuit 21b is a plurality of conductors linearly drawn out from the rigid board portion 22 and is electrically connected to the electronic components 30 mounted on the rigid board portion 22.

[0030] In the embodiment, the plurality of conductors constituting the printed circuit 21b are each provided as linear conductors extending along the third direction. The plurality of conductors constituting the printed circuit 21b are each formed to pass through the land of each through-hole SH formed in the flexible printed circuit board portion 21. With this configuration, the insertion portion of the terminal 11 inserted into the through-hole SH is electrically connected to one of the conductors passing through the through-hole SH via the solder SD1.

[0031] In the embodiment, the flexible printed circuit board portion 21 has a plurality of through holes SH formed in a staggered pattern, allowing many through holes SH to be densely packed in the base film 21a. That is, the number of through holes SH per unit area of the base film 21a can be increased. This allows the connector 10 to be multipolarized while preventing the connector 10 from becoming larger. Furthermore, the insertion portions of the terminals 11 located at different positions in the third direction Z can be electrically connected to the rigid board portion 22 by separate straight conductors. This allows each of the multiple terminals 11 to be electrically connected to the rigid board portion 22 by straight conductors, eliminating the need to create a complex circuit and facilitating the creation of the printed circuit 21b.

[0032] In the flat wiring material 20 of the embodiment, the flexible printed circuit board portion 21 has a bent portion 23 in which one end side to which the rigid board portion 22 is connected is bent toward a direction along the second direction Y. The rigid board portion 22 is arranged to face the terminal holding portion 12 in a direction intersecting the second direction Y (here, the third direction Z) by bending the flexible printed circuit board portion 21 at the bent portion 23. That is, in the flat wiring material 20 of the embodiment, in a state in which the flexible printed circuit board portion 21 is bent at one end side to which the rigid board portion 22 is connected, the flexible printed circuit board portion 21 is positioned facing the terminal holding portion 12 in the second direction Y, and the rigid board portion 22 is positioned facing the terminal holding portion 12 in a direction intersecting the second direction Y (the third direction Z).

[0033] As shown in Figure 1, the rigid board portion 22 is accommodated in the accommodation portion HS of the housing 13 together with the terminal holding portion 12, facing the terminal holding portion 12 in a direction (third direction Z) that intersects the protruding direction of the insertion portion relative to the terminal holding portion 12.

[0034] Next, a method for manufacturing the wire harness 100 according to the embodiment will be described with reference to Fig. 4 to Fig. 8. As shown in Fig. 4, the method for manufacturing the wire harness 100 according to the embodiment includes a terminal holding step S1, an assembling step S2, a laser irradiation step S3, a bending step S4, and a housing accommodating step S5.

[0035] As shown in Fig. 5, in the terminal holding step S1, the corresponding terminals 11 are inserted into the multiple terminal insertion holes 12a of the terminal holding portion 12. Here, in the housing accommodating step described later, each terminal 11 is inserted so that the insertion portion of the terminal 11 protrudes from the end face 12s exposed from the opening 13p of the housing 13. The terminals 11 held by the terminal holding portion 12 are arranged so that the tip positions of the insertion portions of the multiple terminals 11 are located on the same plane on the end face 12s of the terminal holding portion 12. In other words, the insertion portions of the multiple terminals 11 held by the terminal holding portion 12 are arranged with the same protruding length from the end face 12s of the terminal holding portion 12.

[0036] 6, in the assembling process S2, the insertion portion of the terminal 11 is inserted into the through hole SH of the flexible printed circuit board portion 21 in the flat wiring material 20, thereby assembling the flat wiring material 20 to the terminal holding portion 12 in which the terminal 11 is held. That is, the flexible printed circuit board portion 21 is positioned and assembled so as to correspond to the surface from which the insertion portion of the terminal 11 protrudes in the terminal holding portion 12 and the second direction Y. In the assembling process S2, preliminary solder has been applied in advance to the connection portion with the insertion portion of the terminal 11 in the flexible printed circuit board portion 21 (the land portion of the through hole SH) and the connection portion with the electronic component 30 in the rigid board portion 22 of the flat wiring material 20 to be assembled.

[0037] Thereafter, in the laser irradiation process S3, a laser is irradiated onto the flat wiring material 20 to melt the preliminary solder at each connection site, and the solder connection between the flexible printed circuit board portion 21 and the terminal 11 and the solder connection between the rigid board portion 22 and the electronic component 30 are performed simultaneously. In the embodiment, as shown by the arrow Y1 in Fig. 6, the irradiation area of the laser L1 is moved at a constant speed along the third direction Z, thereby performing the solder connection of the terminal 11 and the electronic component 30 to the flat wiring material 20 simultaneously.

[0038] Then, in the bending process S4, as shown by the arrow Y2 in Figure 7, one end side of the flexible printed circuit board portion 21 to which the rigid board portion 22 is connected is bent toward the terminal holding portion 12, so that the rigid board portion 22 faces the terminal holding portion 12 in a direction (third direction Z) that intersects with the protruding direction of the insertion portion relative to the terminal holding portion 12.

[0039] 8, in a housing accommodating step S5, the flat wiring material 20 is assembled, and 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 convex portions 12b and the concave portions 12c of each of the flat plate portions 12A and 12B are fitted with the concave-convex surface 13a of the housing 13. Through the above steps, the wire harness 100 according to the embodiment is manufactured.

[0040] 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.

[0041] In addition, in the above-described embodiment, the insertion portion of the terminal 11 is rod-shaped, but this is not limiting. For example, the insertion portion of the terminal 11 may be cylindrical.

[0042] Furthermore, the number of flat plate portions 12A, 12B constituting the terminal holding portion 12 is not limited to three. For example, the terminal holding portion 12 may be configured by stacking two flat plate portions 12A, 12B (i.e., one flat plate portion 12A and one flat plate portion 12B). Furthermore, the terminal holding portion 12 may be configured by stacking four or more flat plate portions 12A, 12B.

[0043] 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.

[0044] As described above, the wire harness 100 according to the embodiment comprises a connector 10 including a plurality of terminals 11 each having an insertion portion and a terminal holding portion 12 that holds the plurality of terminals 11 arranged in a plurality of rows with the insertion portions protruding, and a flat wiring material 20 including a flexible, flat-plate-shaped flexible printed circuit board portion 21 in which a plurality of through holes SH are formed and which is physically and electrically connected to the terminals 11 via the through holes SH, the flexible printed circuit board portion 21 being arranged to cover the end face 12s of the terminal holding portion 12 from which the insertion portions of the plurality of terminals 11 protrude, and with the insertion portions of the corresponding terminals 11 inserted into each of the plurality of through holes SH, the flexible printed circuit board portion 21 is physically and electrically connected to the insertion portions via solder.

[0045] In the wire harness 100 according to the embodiment, a plurality of terminals 11 are arranged in a plurality of rows, and the insertion portion of each terminal 11 is inserted into the through-hole SH of the flexible printed circuit board portion 21, so that the solder connecting the terminals 11 and the flexible printed circuit board portion 21 can be irradiated with a laser all at once. This configuration allows uniform solder connection without adjusting the laser output. Therefore, in the wire harness 100 according to the embodiment, a plurality of terminals 11 can be properly soldered to the flexible printed circuit board portion 21 of the flat wiring material 20.

[0046] Furthermore, in the wire harness 100 according to the embodiment, the flat wiring material 20 is connected to one end of the flexible printed circuit board portion 21 and has higher rigidity than the flexible printed circuit board portion 21, and further includes a flat rigid board portion 22 to which the electronic component 30 is physically and electrically connected via solder, and when bent at one end side of the flexible printed circuit board portion 21, the flexible printed circuit board portion 21 is positioned opposite the terminal holding portion 12 in the protruding direction of the insertion portion relative to the terminal holding portion 12, and the rigid board portion 22 is positioned opposite the terminal holding portion 12 in a direction intersecting the protruding direction.

[0047] In the wire harness 100 according to the embodiment, the flat wiring material 20 has a flat rigid board portion 22 on which an electronic component 30 is mounted, and the flexible printed board portion 21 in the flat wiring material 20 is configured to be bendable. With this configuration, for example, it is possible to irradiate a laser not only on the solder connecting the flexible printed board portion 21 and the terminal 11 but also on the solder connecting the rigid board portion 22 and the electronic component 30 all at once. Furthermore, in the wire harness 100 according to the embodiment, by bending the flexible printed board portion 21, the rigid board portion 22 is placed opposite and overlapped with the terminal holding portion 12 in a direction intersecting the protrusion direction of the insertion portion. With this state, for example, the rigid board portion 22 can be accommodated in a housing 13 or the like in a state where it overlaps with the terminal holding portion 12, thereby making it possible to miniaturize the wire harness 100. Furthermore, by mounting electronic components 30 on rigid board section 22 adjacent to flexible printed board section 21, the influence of vibrations caused by fit backlash with the mating connector can be suppressed.

[0048] In addition, in the wire harness 100 according to the embodiment, the terminal holding portion 12 is configured to include a plurality of flat plate portions 12A, 12B each holding one of the rows of the plurality of terminals 11, and the connector 10 further includes a housing 13 that holds the plurality of flat plate portions 12A, 12B stacked in the thickness direction of the plurality of flat plate portions 12A, 12B with the end face 12s of the terminal holding portion 12 exposed outward.

[0049] In the wire harness 100 according to the embodiment, by stacking multiple flat plate portions 12A, 12B, the number of terminals 11 connected to the flat wiring material 20 can be increased, and the connector 10 can be made multi-polar while preventing the connector 10 from becoming larger.

[0050] In the wire harness 100 according to the embodiment, the terminal holding portion 12 holds the multiple terminals 11 in one adjacent row by arranging them in a shifted arrangement in the row direction of the multiple terminals 11 relative to the multiple terminals 11 in the other adjacent row.

[0051] In the wire harness 100 according to the embodiment, the terminals 11 are arranged so that their relative positions are shifted from one row to another, which makes it easier for an operator to check whether the flexible printed circuit board portion 21 and the terminals 11 are properly connected by soldering. Furthermore, this configuration allows the terminals 11 to be arranged more compactly and densely.

[0052] The contents disclosed in the above embodiments can be implemented in appropriate combinations. [Explanation of symbols]
