[0048] like Figure 1 As shown, the wiring harness 1 of this embodiment includes a connector 2 and flexible printed wiring boards 10 and 20. The wiring harness 1 is installed in a vehicle such as an automobile. The wiring harness 1 can be connected to a device located on the dashboard. The connector 2 mates with a mating connector 100. The mating connector 100 is located in the housing of a device such as a display or an instrument. The wiring harness 1 can also connect a device having the mating connector 100 to a control device that controls the device. The flexible printed wiring boards 10 and 20 have printed circuits including power lines and signal lines.

[0049] The mating connector 100 includes a housing 110 and a plurality of terminals 120 held by the housing 110. The connector 2 connects the printed circuits of the flexible printed wiring boards 10 and 20 to the terminals 120. The illustrated connector 2 is a lever-type connector having a lever 7. The connector 2 can be mated with the housing 110 of the mating connector 100 by a force-enhancing mechanism including the lever 7.

[0050] like Figure 2 As shown, connector 2 includes an outer housing 3, multiple inner housings 4, multiple terminals 5, a first flexible printed wiring board 10, a second flexible printed wiring board 20, and a cover 6. The outer housing 3 and inner housing 4 are molded from, for example, an insulating synthetic resin. The outer housing 3, in this example, has a square cylindrical shape and includes a housing portion 31 for accommodating the multiple inner housings 4.

[0051] The inner housing 4 is a member that holds and arranges the terminals 5. The inner housing 4 has cavities for inserting the terminals 5. A plurality of inner housings 4 are stacked and housed in the housing portion 31 of the outer housing 3.

[0052] In the following description, the direction in which the multiple inner housings 4 are stacked is referred to as the "first direction X." Furthermore, the direction in which the inner housings 4 are inserted into the outer housing 3 is referred to as the "third direction Z." The third direction Z is orthogonal to the first direction X. Furthermore, the direction orthogonal to both the first and third directions Z is referred to as the "second direction Y." The second direction Y is the direction in which the terminals 5 in each inner housing 4 are arranged. In this embodiment, each inner housing 4 linearly arranges and holds the multiple terminals 5 in the second direction Y.

[0053] Flexible printed wiring boards 10 and 20 are flexible, film-like circuit bodies. First flexible printed wiring board 10 and second flexible printed wiring board 20 are independent wiring boards. Terminals 5 are inserted into through-holes in flexible printed wiring boards 10 and 20 and bonded to the printed circuits of these boards.

[0054] The cover 6 covers the joints between the flexible printed wiring boards 10 and 20 and the terminals 5 and is assembled to the outer housing 3. As will be described later, the cover 6 of this embodiment is configured to hold the two flexible printed wiring boards 10 and 20 in an overlapping state.

[0055] like Figure 3 As shown, the outer shell 3 has a cylindrical portion 32 and a bottom wall 33. The cylindrical portion 32 has a square cylindrical shape and includes a pair of main walls 32a and a pair of side walls 32b. The pair of main walls 32a oppose each other in the first direction X and extend in the second direction Y. A cylindrical shaft portion 32c is provided on the outer side of the main walls 32a. The shaft portion 32c rotatably supports the rod 7.

[0056] The pair of side walls 32b face each other in the second direction Y and extend in the first direction X. A plurality of ribs 32d are provided on the inner side surfaces of the side walls 32b for guiding the inner housing 4. The ribs 32d are protrusions that protrude in the second direction Y and extend linearly in the third direction Z.

[0057] The bottom wall 33 closes one end of the cylindrical portion 32. In other words, the outer housing 3 is a cylindrical component with a bottom. The cylindrical portion 32 and the bottom wall 33 form the receiving portion 31. The bottom wall 33 is provided with a plurality of through-holes 33a. The terminals 120 of the mating connector 100 are inserted into the through-holes 33a and connected to the terminals 5. The plurality of through-holes 33a are arranged in a plurality of rows. The through-holes 33a in each row are aligned in the second direction Y.

[0058] like Figure 4 As shown, the multiple inner housings 4 include a first-shaped housing 4A and a second-shaped housing 4B. The first-shaped housing 4A and the second-shaped housing 4B are rectangular flat plates. The first-shaped housing 4A has multiple first cavities 45 for holding the terminals 5. The multiple first cavities 45 are arranged in the second direction Y and extend through the first-shaped housing 4A along the third direction Z. The second-shaped housing 4B has multiple second cavities 46 for holding the terminals 5. The second cavities 46 are arranged in the second direction Y and extend through the second-shaped housing 4B along the third direction Z.

[0059] The first cavity 45 and the second cavity 46 are arranged so that their positions in the second direction Y are offset. The second cavity 46 is located between two adjacent first cavities 45 in the second direction Y. Therefore, the first cavity 45 and the second cavity 46 hold the plurality of terminals 5 arranged in a zigzag pattern.

[0060] The wire harness 1 of this embodiment includes a plurality of stackable inner housings 4, thereby being able to accommodate changes in the specifications of the connector 2. For example, when different terminals 5 are used depending on the connector size of the terminals 120 of the mating connector 100, this can be accommodated by changing the inner housing 4.

[0061] The first-shaped shell 4A has a first surface 41 and a second surface 42. The first surface 41 and the second surface 42 are two main surfaces of the first-shaped shell 4A, and face opposite sides to each other. The second-shaped shell 4B has a first surface 43 and a second surface 44. The first surface 43 and the second surface 44 are two main surfaces of the second-shaped shell 4B, and face opposite sides to each other. The two shells 4A and 4B can be stacked so that the first surface 41 and the second surface 44 are opposite to each other. In addition, the two shells 4A and 4B can be stacked so that the first surface 43 and the second surface 42 are opposite to each other. That is, the first-shaped shell 4A and the second-shaped shell 4B are configured to be able to be stacked alternately.

[0062] The first-shaped housing 4A includes a first protrusion 41a and a first recess 42a. The first protrusion 41a is provided on the first surface 41. The first recess 42a is provided on the second surface 42. The second-shaped housing 4B includes a second protrusion 43a and a second recess 44a. The second protrusion 43a is provided on the first surface 43. The second recess 44a is provided on the second surface 44. The first protrusion 41a can be fitted with the second recess 44a, and the second protrusion 43a can be fitted with the first recess 42a. The first protrusion 41a is provided with an engaging portion 41b that engages with the second recess 44a. Similarly, the second protrusion 43a is provided with an engaging portion 43b that engages with the first recess 42a.

[0063] The first-shaped housing 4A is provided with a first supporting protrusion 47. The second-shaped housing 4B is provided with a second supporting protrusion 48. Support protrusions 47 and 48 are inserted into the flexible printed wiring boards 10 and 20 to reduce stress on the printed circuits and joints. The first supporting protrusion 47 is located at one end in the second direction Y, and the second supporting protrusion 48 is located at the other end in the second direction Y.

[0064] like Figure 5As shown, the terminal 5 has a connecting portion 51 and an inserting portion 52. The terminal 5 is formed of a conductive metal plate. The connecting portion 51 is disposed at the first end 5a of the terminal 5, and the inserting portion 52 is disposed at the second end 5b of the terminal 5. The connecting portion 51 is the portion that connects to the terminal 120 of the mating connector 100. The illustrated connecting portion 51 has a square cylindrical shape into which the terminal 120 is inserted. The connecting portion 51 is inserted into and retained in the cavities 45 and 46 of the inner housing 4.

[0065] Insertion portion 52 is inserted into the through-hole of flexible printed wiring boards 10 and 20. Insertion portion 52 is cylindrical in shape. A tapered portion 52a is provided at the distal end of insertion portion 52. Alternatively, insertion portion 52 may be rod-shaped with no internal space, such as a cylindrical shape.

[0066] like Figure 6 As shown, first flexible printed wiring board 10 includes base film 11, printed circuit 12, and cover layer 13. Base film 11 and cover layer 13 are films formed of insulating synthetic resin. Printed circuit 12 is a conductive metal foil formed on base film 11. Cover layer 13 covers the pattern of printed circuit 12 and has openings 13a and 13b that expose pads 16b and 17b.

[0067] like Figure 7 As shown, the printed circuit 12 includes a first circuit group 14 and a second circuit group 15. The first circuit group 14 includes a plurality of circuits 16 extending in a first direction X. The plurality of circuits 16 are arranged in a second direction Y. The second circuit group 15 includes a plurality of circuits 17 extending in the first direction X. The plurality of circuits 17 are arranged in the second direction Y. The printed circuit 12 is constructed by alternately arranging one circuit 16 in the first circuit group 14 and one circuit 17 in the second circuit group 15.

[0068] Circuit 16 includes a pattern 16a and a pad 16b disposed at an end of pattern 16a. Circuit 17 includes a pattern 17a and a pad 17b disposed at an end of pattern 17a. Multiple pads 16b are arranged in a straight line along the second direction Y. Multiple pads 17b are arranged in a straight line along the second direction Y. In the first direction X, the positions of pads 17b are offset relative to the positions of pads 16b. More specifically, pads 17b protrude relative to pads 16b toward the end 11a of base film 11. Therefore, pattern 17a passes between two adjacent pads 16b.

[0069] The through hole 16c for inserting the insertion portion 52 of the terminal 5 is formed in the pad 16b. The through hole 16c penetrates the base film 11. Similarly, the through hole 17c is formed in the pad 17b. The through hole 17c penetrates the base film 11. In the first flexible printed wiring board 10, the through holes 16c and the through holes 17c are arranged in a zigzag shape. Figure 6 As shown, the opening 13a of the cover layer 13 exposes the pad 16b of the first circuit group 14. The opening 13b exposes the pad 17b of the second circuit group 15.

[0070] The first flexible printed wiring board 10 is provided with two through-holes 10a and 10b. Through-holes 10a and 10b are arranged at the ends of the second direction Y, sandwiching the printed circuit 12 therebetween. Through-hole 10a is aligned with opening 13a and arranged on an extension line of the plurality of solder pads 16b in the second direction Y. Through-hole 10b is aligned with opening 13b and arranged on an extension line of the plurality of solder pads 17b in the second direction Y. Support protrusion 47 of the first-shaped housing 4A is inserted into one of the two through-holes 10a and 10b. Support protrusion 48 of the second-shaped housing 4B is inserted into the other of the two through-holes 10a and 10b.

[0071] The second flexible printed wiring board 20 is configured similarly to the first flexible printed wiring board 10. Figure 8 As shown, the second flexible printed wiring board 20 includes a base film 21, a printed circuit 22, and a cover layer 23. The cover layer 23 covers the pattern of the printed circuit 22 and has openings 23a and 23b that expose the pads 26b and 27b.

[0072] like Figure 9 As shown, the printed circuit 22 includes a first circuit group 24 and a second circuit group 25. The first circuit group 24 includes a plurality of circuits 26 extending in a first direction X. The plurality of circuits 26 are arranged in a second direction Y. The second circuit group 25 includes a plurality of circuits 27 extending in the first direction X. The plurality of circuits 27 are arranged in the second direction Y. The printed circuit 22 is constructed by alternately arranging one circuit 26 of the first circuit group 24 and one circuit 27 of the second circuit group 25.

[0073] Circuit 26 includes a pattern 26a and a pad 26b disposed at the end of pattern 26a. Circuit 27 includes a pattern 27a and a pad 27b disposed at the end of pattern 27a. Multiple pads 26b and multiple pads 27b are arranged linearly along the second direction Y. Pads 27b protrude toward end 21a of base film 21 relative to pads 26b. Pattern 27a passes between two adjacent pads 26b.

[0074] The through hole 26c for inserting the insertion portion 52 of the terminal 5 is formed in the pad 26b. The through hole 27c is formed in the pad 27b. That is, in the second flexible printed wiring board 20, the through hole 26c and the through hole 27c are arranged in a zigzag shape. Figure 8As shown, the opening 23a of the cover layer 23 exposes the pad 26b of the first circuit group 24. The opening 23b exposes the pad 27b of the second circuit group 25.

[0075] The second flexible printed wiring board 20 is provided with two through-holes 20a and 20b. The two through-holes 20a and 20b are arranged at the ends in the second direction Y, sandwiching the printed circuit 22. The through-hole 20a is aligned with the opening 23a and is arranged on an extension line of the plurality of solder pads 26b in the second direction Y. The through-hole 20b is aligned with the opening 23b and is arranged on an extension line of the plurality of solder pads 27b in the second direction Y. The support protrusion 47 of the first-shaped housing 4A is inserted into one of the two through-holes 20a and 20b. The support protrusion 48 of the second-shaped housing 4B is inserted into the other of the two through-holes 20a and 20b.

[0076] like Figure 2 As shown, the cover 6 includes a main body 61, a retaining portion 62, and a hinge portion 63. The cover 6 is molded from, for example, an insulating synthetic resin. The main body 61 covers the junction between the flexible printed wiring boards 10 and 20 and the terminals 5 and engages with the outer housing 3. The retaining portion 62 holds the flexible printed wiring boards 10 and 20 between the retaining portion 62 and the main body 61. The hinge portion 63 connects the main body 61 and retaining portion 62 and is flexible.

[0077] like Figure 10 As shown, the main body 61 has a covering portion 64 that covers the joint portion and four legs 65. The covering portion 64 is in the shape of a rectangular flat plate. The legs 65 are arranged at both ends of the covering portion 64 in the second direction Y. The legs 65 are the parts that engage with the outer shell 3 and protrude from the covering portion 64 in the third direction Z. An engaging recess 65a and an engaging protrusion 65b are provided on the legs 65. The engaging recess 65a is formed on the inner side surface of the leg 65 that is opposite to the outer shell 3. The engaging recess 65a is respectively provided on the four legs 65. As shown Figure 2 As shown, an engaging protrusion 34 is provided on the outer side surface of the outer shell 3. The engaging recess 65a of the cover 6 engages with the engaging protrusion 34.

[0078] The engaging protrusion 65b engages with the holding portion 62 to lock the holding portion 62. The engaging protrusion 65b is provided on two adjacent leg portions 65. The engaging protrusion 65b protrudes in the second direction Y from the outer side surface on the side opposite to the engaging recess 65a side.

[0079] The retaining portion 62 is aligned with the main body 61 in the second direction Y. The retaining portion 62 includes a first retaining portion 62A and a second retaining portion 62B. The first retaining portion 62A and the second retaining portion 62B are aligned in the first direction X. The first retaining portion 62A and the second retaining portion 62B are rectangular in shape when viewed from above. A slit 66 is provided between the first retaining portion 62A and the second retaining portion 62B. Therefore, the first retaining portion 62A and the second retaining portion 62B are independent of each other. The first retaining portion 62A retains the first flexible printed wiring board 10. The second retaining portion 62B retains the second flexible printed wiring board 20.

[0080] The hinge portion 63 is disposed at the end of the main body 61 opposite the engaging protrusion 65b. The hinge portion 63 includes a first hinge portion 63A and a second hinge portion 63B. The first hinge portion 63A connects the first retaining portion 62A to the main body 61, and the second hinge portion 63B connects the second retaining portion 62B to the main body 61. The hinge portion 63 extends from the end of the cover portion 64 in the second direction Y in the second direction Y. Engaging portions 62c that engage with the engaging protrusion 65b are provided at the ends of the first retaining portion 62A and the second retaining portion 62B.

[0081] The covering portion 64 is provided with a rib 64a that restricts the bending of the flexible printed wiring boards 10 and 20. The rib 64a is located on the surface facing the retaining portion 62 and extends in the second direction Y. The cross-sectional shape of the rib 64a in the example is triangular. In other words, the cross-sectional shape of the rib 64a is tapered, with its width in the first direction X gradually narrowing toward the end in the protruding direction. The first retaining portion 62A and the second retaining portion 62B are provided with inclined surfaces 62d corresponding to the rib 64a. The inclined surfaces 62d are located at the ends adjacent to the slits 66. The rib 64a and the inclined surfaces 62d ensure that the bending angle of the flexible printed wiring boards 10 and 20 is obtuse.

[0082] The following describes a method for manufacturing the wire harness 1 of this embodiment. The method includes inserting the inner housing, inserting the terminals, placing the flexible printed wiring board, joining the terminals, attaching the cover, regulating the orientation of the wiring board, and assembling the lever.

[0083] Figure 11 The step of inserting the inner housing is shown. In this process, multiple stacked inner housings 4 are inserted into the outer housing 3. Housings 4A of the first shape and housings 4B of the second shape are inserted into the outer housing 3 in an alternating, overlapping manner. The illustrated connector 2 includes two housings 4A of the first shape and two housings 4B of the second shape. The multiple inner housings 4 are inserted into the accommodating portion 31 along the third direction Z while being guided by the ribs 32d. The multiple inner housings 4 are retained by the accommodating portion 31. The inner housing 4 may also have an engaging portion that engages with the outer housing 3.

[0084] Figure 12 The terminal insertion process is shown. Multiple terminals 5 are inserted into cavities 45 of the first-shaped housing 4A and cavities 46 of the second-shaped housing 4B. Connecting portions 51 of terminals 5 are inserted into cavities 45 and 46. Inner housing 4 holds connecting portions 51 so that insertion portions 52 of terminals 5 protrude from cavities 45 and 46. This forms four rows of insertion portions 52 arranged in the second direction Y. These four rows are arranged in the first direction X.

[0085] Figure 13 This figure shows the process of installing the flexible printed wiring board. In this process, the insertion portions 52 of the terminals 5 are inserted into the first flexible printed wiring board 10 and the second flexible printed wiring board 20. More specifically, two rows of insertion portions 52 are inserted into the first flexible printed wiring board 10, and another two rows of insertion portions 52 are inserted into the second flexible printed wiring board 20.

[0086] Insertion portion 52 corresponding to first flexible printed wiring board 10 is inserted into pad 16b of first circuit group 14 and pad 17b of second circuit group 15. Insertion portion 52 corresponding to second flexible printed wiring board 20 is inserted into pad 26b of first circuit group 24 and pad 27b of second circuit group 25. Furthermore, support protrusions 47 and 48 are inserted into through-holes of flexible printed wiring boards 10 and 20.

[0087] like Figure 14 As shown, the plurality of terminals 5 include a first terminal group 5A and a second terminal group 5B. The first terminal group 5A is a group of terminals 5 connected to the first flexible printed wiring board 10. The first terminal group 5A includes two rows of terminals 5 arranged along the second direction Y. The first terminal group 5A is the terminal arranged on the first side X1 among the plurality of terminals 5 included in the connector 2. The second terminal group 5B is a group of terminals 5 connected to the second flexible printed wiring board 20. The second terminal group 5B includes two rows of terminals 5 arranged along the second direction Y. The second terminal group 5B is the terminal arranged on the second side X2 among the plurality of terminals 5 included in the connector 2.

[0088] The first flexible printed wiring board 10 has pads 16b and 17b connected to the insertion portion 52 of the first terminal group 5A. Figure 7 As shown, the pads 16b and 17b have through holes 16c and 17c. The insertion portion 52 of the first terminal group 5A is inserted into the through holes 16c and 17c. Figure 14 As shown, one row of insertion portions 52 of the first terminal group 5A is inserted into the pad 16b, and the other row of insertion portions 52 is inserted into the pad 17b.

[0089] The second flexible printed wiring board 20 has pads 26b and 27b connected to the insertion portion 52 of the second terminal group 5B. Figure 9As shown, the pads 26b and 27b have through holes 26c and 27c. The insertion portion 52 of the second terminal group 5B is inserted into the through holes 26c and 27c. Figure 14 As shown, one row of insertion portions 52 of the second terminal group 5B is inserted into the pad 26b, and another row of insertion portions 52 is inserted into the pad 27b.

[0090] The joining process is a process of joining the insertion portion 52 of the terminal 5 to the pads 16b, 17b, 26b, and 27b. In the wiring harness 1 of this embodiment, the insertion portion 52 is soldered to the pads 16b, 17b, 26b, and 27b. Alternatively, solder paste may be pre-coated on the pads 16b, 17b, 26b, and 27b. In this case, during the joining process, welding can be performed by irradiating the solder paste with a laser. For example, all the pads 16b, 17b, 26b, and 27b can be joined to the insertion portion 52 by a single irradiation. However, the welding method is not limited to laser irradiation and may also be a reflow oven or other method.

[0091] The printed circuit 12 of the first flexible printed wiring board 10 extends from the first terminal group 5A toward the first side X1. The printed circuit 22 of the second flexible printed wiring board 20 extends from the second terminal group 5B toward the second side X2. Figure 14 In the illustrated wire harness 1 , the first side X1 is one side in the first direction X, and the second side X2 is the other side in the first direction X. That is, the two printed circuits 12 and 22 extend toward opposite sides to each other.

[0092] In the process of installing the cover, if Figure 15 As shown, the main body 61 of the cover 6 is mounted on the outer housing 3. The cover portion 64 of the main body 61 covers and protects the joints between the flexible printed wiring boards 10 and 20 and the terminals 5. Specifically, the cover portion 64 covers and protects the insertion portions 52 of the terminals 5 and the pads 16b, 17b, 26b, and 27b of the flexible printed wiring boards 10 and 20. When the main body 61 is assembled to the outer housing 3, the retaining portion 62 is positioned offset in the second direction Y relative to the flexible printed wiring boards 10 and 20.

[0093] The step of regulating the direction of the wiring board includes the step of bending the wiring board and the step of holding the wiring board. Figure 16 This diagram illustrates the process of bending a wiring board. In this process, first and second flexible printed wiring boards 10 and 20 are bent so that they overlap. The two flexible printed wiring boards 10 and 20 are bent so that they enclose cover 64, with cover layers 13 and 23 facing each other. In other words, the two flexible printed wiring boards 10 and 20 are bent 180 degrees along cover 64 into a U-shape.

[0094] Figure 17This figure explains the process of holding the wiring boards. In the process of holding the wiring boards, two flexible printed wiring boards 10 and 20 are held by holding portion 62 of cover 6. Cover 6 of this embodiment holds two flexible printed wiring boards 10 and 20 in an overlapping state.

[0095] The first holding portion 62A engages with the main body 61 while bending the first hinge portion 63A. The first holding portion 62A sandwiches the first flexible printed wiring board 10 between the first holding portion 62A and the main body 61. The second holding portion 62B engages with the main body 61 while bending the second hinge portion 63B. The second holding portion 62B sandwiches the second flexible printed wiring board 20 between the second holding portion 62B and the main body 61. The two flexible printed wiring boards 10 and 20 are drawn out from the slit 66 between the first holding portion 62A and the second holding portion 62B.

[0096] Slit 66 serves as an exit portion for extending the overlapping flexible printed wiring boards 10 and 20. The direction in which the flexible printed wiring boards 10 and 20 extend is the third direction Z. More specifically, the flexible printed wiring boards 10 and 20 extend from the retaining portion 62 toward the side opposite to the outer housing 3 along the third direction Z. In other words, the flexible printed wiring boards 10 and 20 extend from the retaining portion 62 toward the direction in which the insertion portion 52 of the terminal 5 protrudes from the inner housing 4.

[0097] Figure 18 FIG. 2 shows the bent shapes of the flexible printed wiring boards 10 and 20. Figure 18 As shown, the first flexible printed wiring board 10 is held by the cover 6 with a first curved portion 10c, a second curved portion 10d, and a third curved portion 10e. The first curved portion 10c is bent into a U-shape along the cover 64. The second curved portion 10d is formed at the portion where the rib 64a of the cover 64 rises. The third curved portion 10e is formed at the distal end of the rib 64a. The gap between the cover 64 and the first retaining portion 62A is bent to form the second curved portion 10d and the third curved portion 10e on the first flexible printed wiring board 10. The internal angles of the first curved portion 10c and the second curved portion 10d are both obtuse.

[0098] The second flexible printed wiring board 20 is held by the cover 6 in a state having a first curved portion 20c, a second curved portion 20d, and a third curved portion 20e. The first curved portion 20c is bent into a U-shape along the cover portion 64. The two first curved portions 10c, 20c are bent toward opposite sides. That is, the first curved portion 10c of the first flexible printed wiring board 10 has a curved shape that is convex toward the first side X1. On the other hand, the first curved portion 20c of the second flexible printed wiring board 20 has a curved shape that is convex toward the second side X2. The second curved portion 20d is formed at the portion where the rib 64a stands upright. The third curved portion 20e is formed at the distal end of the rib 64a. The internal angles of the second curved portion 20d and the third curved portion 20e are both obtuse angles.

[0099] The two flexible printed wiring boards 10 and 20 overlap at the third bends 10e and 20e and extend in the third direction Z. The cover 6 of this embodiment is configured to prevent the flexible printed wiring boards 10 and 20 from forming excessively curved portions. For example, the corners corresponding to the first bends 10c and 20c in the cover portion 64 are chamfered into an arc shape. Furthermore, the portions forming the second bends 10d and 20d and the third bends 10e and 20e are bent at an angle greater than a right angle. Therefore, the cover 6 of this embodiment can restrict the path of the flexible printed wiring boards 10 and 20 without causing them to bend excessively.

[0100] Thus, the cover 6 of this embodiment not only protects the junction between the flexible printed wiring boards 10 and 20 and the terminals 5 but also restricts the path of the flexible printed wiring boards 10 and 20. The cover 6 allows the two flexible printed wiring boards 10 and 20 to extend in an overlapping manner. This overlapping of the two flexible printed wiring boards 10 and 20 facilitates handling of the connector 2. The two flexible printed wiring boards 10 and 20 are connected to a device via a connector or the like. The two flexible printed wiring boards 10 and 20 can be connected to the same device or to different devices.

[0101] Figure 19 The figure shows connector 2 assembled with lever 7. During the lever assembly process, lever 7 is assembled to outer housing 3. Connector 2 with lever 7 assembled is mated with mating connector 100. Rod 7 amplifies the force input to rod 7 and transmits it to mating connector 100, causing mating connector 100 to mate with outer housing 3.

[0102] As described above, the wiring harness 1 of this embodiment includes a connector 2, a first flexible printed wiring board 10, a second flexible printed wiring board 20, and a cover 6 serving as a retaining member. The connector 2 includes a plurality of terminals 5 having a rod-shaped or cylindrical insertion portion 52, and housings 3 and 4 that hold the plurality of terminals 5 arranged in a plurality of rows with the insertion portions 52 protruding. The plurality of rows are arranged in a first direction X. The plurality of terminals 5 include a first terminal group 5A arranged on a first side X1 in the first direction X, and a second terminal group 5B arranged on a second side X2 in the first direction X.

[0103] First flexible printed wiring board 10 has through-holes 16c and 17c into which insertion portion 52 of first terminal group 5A is inserted, and printed circuit 12 connected to insertion portion 52 of the first terminal group. Second flexible printed wiring board 20 has through-holes 26c and 27c into which insertion portion 52 of second terminal group 5B is inserted, and printed circuit 22 connected to insertion portion 52 of second terminal group 5B. Cover 6, serving as a retaining member, is attached to housings 3 and 4 and retains first flexible printed wiring board 10 and second flexible printed wiring board 20.

[0104] The cover 6 has an exit portion, and the first flexible printed wiring board 10 and the second flexible printed wiring board 20 that overlap each other extend from the exit portion. The exit portion of the cover 6 is, for example, a slit 66. The wiring harness 1 of this embodiment extends the two flexible printed wiring boards 10 and 20 in an overlapping manner by a retaining component. Therefore, the wiring harness 1 of this embodiment can improve the ease of handling of the wiring harness 1. For example, by bringing the two flexible printed wiring boards 10 and 20 together, the handling of the wiring harness 1 during transportation or laying becomes easier. The two overlapping flexible printed wiring boards 10 and 20 can be directly laid out on the same path, can be laid out on different paths, or can be laid out in a branched manner in the middle.

[0105] The cover 6 of this embodiment holds the first flexible printed wiring board 10 and the second flexible printed wiring board 20 in a folded state, allowing the overlapping first and second flexible printed wiring boards 10, 20 to extend from the outlet portion in the direction of protrusion of the insertion portion 52. This structure is employed, for example, when routing the flexible printed wiring boards 10, 20 along the protrusion direction of the insertion portion 52.

[0106] The cover 6 of this embodiment includes a main body 61 attached to the housings 3 and 4 to cover the insertion portion 52; a retaining portion 62; and a hinge portion 63 connecting the main body 61 and the retaining portion 62. The cover 6 sandwiches the first and second flexible printed wiring boards 10 and 20 between the main body 61 and the retaining portion 62, thereby overlapping the first and second flexible printed wiring boards 10 and 20. The cover 6 of this embodiment not only retains the flexible printed wiring boards 10 and 20 but also protects the junction between the insertion portion 52 and the flexible printed wiring boards 10 and 20.

[0107] The cover 6 of this embodiment includes a main body 61 attached to the housings 3 and 4 so as to cover the insertion portion 52; a first retaining portion 62A; a first hinge portion 63A connecting the main body 61 and the first retaining portion 62A; a second retaining portion 62B; and a second hinge portion 63B connecting the main body 61 and the second retaining portion 62B. The cover 6 sandwiches the first flexible printed wiring board 10 between the main body 61 and the first retaining portion 62A, and the second flexible printed wiring board 20 between the main body 61 and the second retaining portion 62B, allowing the overlapping first and second flexible printed wiring boards 10 and 20 to extend through a slit 66. The slit 66 is a gap between the first and second retaining portions 62A and 62B. Since the first and second retaining portions 62A and 62B are independent, the operation of retaining the flexible printed wiring boards 10 and 20 is improved.

[0108] It should be noted that the number of inner housings 4 included in the connector 2 is not limited to four. For example, the first cavity 45 and the second cavity 46 may be provided in the first-shaped housing 4A, and the first cavity 45 and the second cavity 46 may also be provided in the second-shaped housing 4B. In this case, the number of inner housings 4 included in the connector 2 may also be two.

[0109] The housing of the connector 2 does not need to be divided into the outer housing 3 and the inner housing 4. For example, the outer housing 3 may be provided with the chambers 45 and 46. The connector 2 is not limited to a lever-type connector having the lever 7.

[0110] The main body 61 and the holding portion 62 of the cover 6 may not be integral. For example, the main body 61 and the holding portion 62 may be separate components. In this case, the main body 61 is first mounted on the outer shell 3. Then, as shown in FIG. Figure 16 As shown, the holding portion 62 as a separate component may be assembled to the main body 61 or the outer housing 3 in a state where the flexible printed wiring boards 10 and 20 are bent.

[0111] [First Modification of the Embodiment]

[0112] A first modified example of the embodiment will be described. Figure 201 is a diagram showing a step of bending a wiring board according to a first modification of the embodiment. Figure 21 1 is a diagram showing a process for maintaining a wiring board according to a first modification of the embodiment. Figures 22 to 24 1 is a diagram showing the steps of assembling a rod according to a first modification of the embodiment. Figure 25 1 is a diagram showing a fitting process of a first modified example of the embodiment, Figure 26 is a perspective view showing the wiring harness fully engaged with the mating connector. Figure 27 is a side view showing the wiring harness fully engaged with the mating connector. Figure 28 is a side view showing the wiring harness fully engaged with the mating connector. Figure 29 1 is a diagram showing a step of bending a wiring board according to a first modification of the embodiment. Figure 30 1 and 2 are diagrams showing a process of holding a wiring board according to a first modification of the embodiment. The first modification of the embodiment differs from the above-described embodiment in that, for example, the flexible printed wiring boards 10 and 20 extend in the first direction X.

[0113] The direction in which the two flexible printed wiring boards 10 and 20 extend from the cover 6 may also be the first direction X. For example, Figure 20 As shown, the flexible printed wiring boards 10 and 20 can be drawn out from the cover 6 toward the second side X2 in the first direction X. In this case, in the process of bending the wiring board, as shown in FIG. Figure 20 As shown, the operator bends the first flexible printed wiring board 10 so as to overlap the second flexible printed wiring board 20. The first flexible printed wiring board 10 is folded back so as to be wrapped around the covering portion 64 of the cover 6 and overlaps the second flexible printed wiring board 20.

[0114] Next, the wiring board holding step is performed. In this step, the operator bends the hinge portions 63A and 63B while engaging the first holding portion 62A and the second holding portion 62B with the main body 61. This holds the first flexible printed wiring board 10 between the two holding portions 62A and 62B and the cover portion 64.

[0115] Next, the process of assembling the rod is performed. In the process of assembling the rod, if Figure 22 and Figure 23 As shown, the operator bends the two flexible printed wiring boards 10 and 20 along the side surface 62f of the second holding portion 62B. The flexible printed wiring boards 10 and 20 are bent toward the side opposite to the outer housing 3 side in the third direction Z.

[0116] like Figure 23As shown, the two flexible printed wiring boards 10 and 20 are led out from the end 67 of the cover 6. In other words, the end 67 on the second side X2 of the cover 6 serves as an exit for the flexible printed wiring boards 10 and 20. More specifically, the first flexible printed wiring board 10 extends out of the cover 6 from the gap between the cover portion 64 and the second retaining portion 62B. The second flexible printed wiring board 20 extends out of the cover 6 from the gap between the cover portion 64 and the outer housing 3.

[0117] Then, if Figure 24 As shown, the lever 7 is attached to the outer housing 3. The lever 7 includes a pair of arms 71 and an operating portion 72. The pair of arms 71 are plate-shaped and face each other in the first direction X. The operating portion 72 is the portion to which the operator's operating force is input. The operating portion 72 connects the pair of arms 71 and extends in the first direction X.

[0118] Arm 71 is provided with a guide hole 71a and an abutment portion 71b. Guide hole 71a is an arc-shaped hole for inserting shaft portion 32c of outer housing 3. A support portion for locking abutment portion 71b is provided on the inner wall of housing 110 of mating connector 100. Abutment portion 71b abuts and is locked by the support portion of mating connector 100. The lever 7 rotates about the locked abutment portion 71b, thereby engaging outer housing 3 with housing 110.

[0119] like Figure 24 As shown, the lever 7 is mounted to the outer housing 3 so that the arm 71 is located outside the two overlapping flexible printed wiring boards 10 and 20. Therefore, the flexible printed wiring boards 10 and 20 extend in the third direction Z in the gap between the arm 71 and the cover 6.

[0120] like Figure 25 As shown, the outer housing 3 is inserted into the housing 110 of the mating connector 100 along the third direction Z. When the outer housing 3 is inserted to the half-engaged position, the operator presses the operating portion 72 as indicated by the arrow AR1 to rotate the lever 7. The operator's pressing force is transmitted to the outer housing 3 via the force-increasing mechanism, causing the outer housing 3 to be fully engaged with the housing 110.

[0121] exist Figure 26 as well as Figure 27 1 shows the connector 2 after being fully engaged with the mating connector 100. When fully engaged, the majority of the arm 71 of the lever 7 is accommodated in the housing 110. Figure 27 As shown, the arm 71 is housed in the housing 110 so as not to overlap with the holding portion 62 when viewed from the first direction X. Figure 27 As shown, the gap between the second holding portion 62B and the covering portion 64 is open toward the second side X2. Therefore, the cover 6 of the first modified example of the embodiment can linearly extend the first flexible printed wiring board 10 toward the second side X2.

[0122] The second flexible printed wiring board 20 extends beyond the arm 71 toward the second side X2. Specifically, the second flexible printed wiring board 20 includes a first portion 20f extending in the third direction Z and a second portion 20g extending in the first direction X. The first portion 20f is formed in the gap between the arm 71 and the outer housing 3. The second flexible printed wiring board 20 is bent along the first flexible printed wiring board 10 at the intersection of the first portion 20f and the first flexible printed wiring board 10. This allows the second flexible printed wiring board 20 to overlap with the first flexible printed wiring board 10. Specifically, when the connector 2 is fully mated with the mating connector 100, the flexible printed wiring boards 10, 20, can extend linearly toward the second side X2.

[0123] In this manner, the connector 2 is configured so that the extending direction of the two flexible printed wiring boards 10 and 20 can also be the first direction X. Therefore, the wire harness 1 can flexibly cope with various wiring directions when mounted on a vehicle.

[0124] In addition, if Figure 28 As shown in FIG. 1 , the connector 2 may also extend the flexible printed wiring boards 10 and 20 from the cover 6 toward the first side X1. In this case, as shown in FIG. Figure 29 As shown, in the wiring board bending process, the operator bends the second flexible printed wiring board 20 to overlap the first flexible printed wiring board 10. The second flexible printed wiring board 20 is folded back so as to be wrapped around the covering portion 64 of the cover 6 and overlaps the first flexible printed wiring board 10.

[0125] In the process of holding the wiring board, the second flexible printed wiring board 20 is held between the two holding portions 62A, 62B and the cover portion 64. Then, in the process of assembling the rod, the two flexible printed wiring boards 10, 20 are bent so as to follow the side surface 62e of the first holding portion 62A, and the rod 7 is attached to the outer housing 3. When the connector 2 is completely fitted with the mating connector 100, as shown in FIG. Figure 28 As shown, the flexible printed wiring boards 10 and 20 that overlap each other can be extended linearly toward the first side X1.

[0126] [Second Modification of the Embodiment]

[0127] A second modified example of the embodiment will be described. Figure 31 2 is a cross-sectional view of a wire harness according to a second modification of the embodiment. The second modification of the embodiment differs from the above-described embodiment in, for example, the mounting orientation of the flexible printed wiring boards 10 and 20 relative to the terminals 5 . Figure 31The first flexible printed wiring board 10 is bonded to the first terminal group 5A so as to extend from the first terminal group 5A toward the second side X2 . The second flexible printed wiring board 20 is bonded to the second terminal group 5B so as to extend from the second terminal group 5B toward the first side X1 .

[0128] The two flexible printed wiring boards 10 and 20 are bent and overlapped at a position between the first terminal group 5A and the second terminal group 5B in the third direction Z. The connector 2 of the second modified example may also include a retaining member that is attached to the outer housing 3 so that the two flexible printed wiring boards 10 and 20 extend in the third direction Z.

[0129] Connector 2 can also be configured as a shielded connector. In this case, a conductive shielding layer can be provided on first and second flexible printed wiring boards 10 and 20. When the two flexible printed wiring boards 10 and 20 are stacked, the shielding layer is positioned on the outside. The shielding layer can also be a conductive paste applied to the outer surfaces of base films 11 and 21.

[0130] When connector 2 is a shielded connector, connector 2 may include a conductive portion for grounding the shield layer. The grounding conductive portion grounds the shield layer of flexible printed wiring boards 10 and 20 to a metal housing or the like. The grounding conductive portion may be a conductive member provided on outer housing 3 or a shield shell covering outer housing 3.

[0131] The contents disclosed in the above-mentioned embodiments and modifications can be implemented in appropriate combinations.
