[0010] As in Fig. As shown in Figure 1, a cable harness 1 according to the present embodiment comprises a connector 2 and flexible printed circuit boards 10 and 20. The cable harness 1 is installed, for example, in a vehicle, such as an automobile. The cable harness 1 can be connected to devices located in an instrument panel. The connector 2 is configured to connect to a mating connector 100. The mating connector 100 is located on the housing of a device, such as a display or measuring instrument. The cable harness 1 can connect devices via the mating connector 100 to a control unit that controls the devices. The flexible printed circuit boards 10 and 20 each have a printed circuit with a power line and a signal line.

[0011] The mating connector 100 has a housing 110 and a plurality of terminals 120 held by the housing 110. The connector 2 connects the printed circuit of the flexible printed circuit boards 10 and 20 to the terminal 120. The illustrated connector 2 is a lever-type connector with a lever 7. The connector 2 is able to connect to the housing 110 of the mating connector 100 using a force-multiplying mechanism comprising the lever 7.

[0012] As in Fig. As shown in Figure 2, the connector 2 comprises an outer housing 3, a plurality of inner housings 4, a plurality of terminals 5, the first flexible printed circuit board 10, the second flexible printed circuit board 20, and a cover 6. The outer housing 3 and the inner housing 4 are, for example, cast from an insulating resin. The outer housing 3 shown has a rectangular, tubular shape and includes a housing section 31 that accommodates the multiple inner housings 4.

[0013] The inner housing 4 is a component that accommodates the terminals 5 and serves to arrange them. The inner housing 4 has a recess into which the terminals 5 are inserted. The multiple inner housings 4 are stacked and housed in the storage compartment 31 of the outer housing 3.

[0014] In the following description, the direction in which the multiple inner housings 4 are stacked is referred to as a “first direction X”. The direction in which the inner housings 4 are inserted into the outer housing 3 is referred to as a “third direction Z”. The third direction Z is orthogonal to the first direction X. Furthermore, the direction that is orthogonal to both the first direction X and the third direction Z is referred to as a “second direction Y”. The second direction Y corresponds to the orientation direction of the terminals 5 in each inner housing 4. In the present embodiment, each inner housing 4 holds the multiple terminals 5, which are oriented linearly in the second direction Y.

[0015] The flexible printed circuit boards 10 and 20 are flexible, foil-like circuit bodies. The first flexible printed circuit board 10 and the second flexible printed circuit board 20 are independent of each other. The terminals 5 are inserted into through-holes of the flexible printed circuit boards 10 and 20 and connected to the printed circuits of the flexible printed circuit boards 10 and 20.

[0016] The cover 6 is attached to the outer housing 3 and covers a connection between the flexible printed circuit boards 10 and 20 and the terminals 5. The cover 6 of the present embodiment is configured to hold the flexible printed circuit boards 10 and 20 in a state in which the two flexible printed circuit boards 10 and 20 overlap each other, as will be described later.

[0017] As in Fig. As shown in Figure 3, the outer housing 3 has a tubular section 32 and a bottom wall 33. The tubular section 32 has a rectangular, tubular shape and comprises a pair of main walls 32a and a pair of side walls 32b. The two main walls 32a face each other in the first direction X and extend in the second direction Y. A columnar shaft section 32c is provided on the outer surface of the main wall 32a. The shaft section 32c rotatably supports the lever 7.

[0018] The two side walls 32b face each other in the second direction Y and extend in the first direction X. A plurality of ribs 32d, which guide the inner housing 4, are provided on the inner surface of the side wall 32b. The ribs 32d are projections that extend in the second direction Y and linearly in the third direction Z.

[0019] The bottom wall 33 closes one end of the tubular section 32. In other words, the outer housing 3 is a tubular element with a closed bottom. The tubular section 32 and the bottom wall 33 form the housing section 31. The bottom wall 33 is provided with multiple 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 multiple through-holes 33a are arranged in multiple rows. The through-holes 33a in each row are oriented in the second direction Y.

[0020] As in Fig. As shown in Figure 4, the multiple inner housings 4 have a first housing form 4A and a second housing form 4B. The first housing form 4A and the second housing form 4B are rectangular flat plates. The first housing form 4A has a plurality of first recesses 45 for receiving the terminals 5. The multiple first recesses 45 are oriented in the second direction Y and penetrate the first housing form 4A in the third direction Z. The second housing form 4B has a plurality of second recesses 46 for receiving the terminals 5. The second recesses 46 are oriented in the second direction Y and penetrate the second housing form 4B in the third direction Z.

[0021] The first recess 45 and the second recess 46 are arranged such that their positions are offset in the second direction Y. The second recesses 46 are located between two adjacent first recesses 45 in the second direction Y. Thus, the first recesses 45 and the second recesses 46 hold the multiple terminals 5 in a zigzag arrangement.

[0022] In the cable harness 1 of the present embodiment, the inclusion of the multiply stackable inner housings 4 enables adaptation to specification changes of the connector 2. If, for example, different terminals 5 are used depending on the branching of the terminals 120 of the mating connector 100, the modification of the inner housing 4 enables adaptation to such specification changes.

[0023] The first housing shape 4A has a first surface 41 and a second surface 42. The first surface 41 and the second surface 42 are two principal surfaces of the first housing shape 4A and face in opposite directions. The second housing shape 4B has a first surface 43 and a second surface 44. The first surface 43 and the second surface 44 are two principal surfaces of the second housing shape 4B and face in opposite directions. The two housing shapes 4A and 4B are stackable, with the first surface 41 facing the second surface 44. Furthermore, the two housing shapes 4A and 4B are stackable such that the first surface 43 is opposite the second surface 42. In other words, the first housing shape 4A and the second housing shape 4B are configured to be stackable by alternately overlapping each other.

[0024] The first housing form 4A has a first projection 41a and a first recess 42a. The first projection 41a is located on the first surface 41. The first recess 42a is located on the second surface 42. The second housing form 4B has a second projection 43a and a second recess 44a. The second projection 43a is located on the first surface 43. The second recess 44a is located on the second surface 44. The first projection 41a can be connected to the second recess 44a, and the second projection 43a to the first recess 42a. The first projection 41a is provided with an engagement section 41b that engages in the second recess 44a. Similarly, the second projection 43a is provided with an engagement section 43b that engages in the first recess 42a.

[0025] The first housing form 4A is provided with a first support projection 47. The second housing form 4B is provided with a second support projection 48. The support projections 47 and 48 are inserted into the flexible printed circuit boards 10 and 20 to minimize the stress on the printed circuit board and the connection. The first support projection 47 is arranged at one end in the second direction Y, and the second support projection 48 is arranged at the other end in the second direction Y.

[0026] As in Fig. As shown in Figure 5, the terminal 5 has a connecting section 51 and an insert section 52. The terminal 5 is formed from a conductive metal plate. The connecting section 51 is arranged at a first end section 5a of the terminal 5, and the insert section 52 is arranged at a second end section 5b of the terminal 5. The connecting section 51 is a section that is connected to the terminal 120 of the mating connector 100. The connecting section 51 shown has a rectangular, tubular shape into which the terminal 120 is inserted. The connecting section 51 is inserted into and held in the recesses 45 and 46 of the inner housing 4.

[0027] Insert section 52 is a section that is inserted into a through-hole in each of the flexible printed circuit boards 10 and 20. Insert section 52 has a tubular shape. A tapered section 52a with a gradually tapered shape is provided at a distal end of insert section 52. Alternatively, insert section 52 can be a solid rod without an interior and, for example, have a column-like shape.

[0028] As in Fig. As shown in Figure 6, the first flexible printed circuit board 10 comprises a base film 11, a printed circuit board 12, and a cover layer 13. The base film 11 and the cover layer 13 are insulating films made of a synthetic resin. The printed circuit 12 is a conductive metal foil applied to the base film 11. The cover layer 13 covers the pattern of the printed circuit 12 and has openings 13a and 13b that expose solder pads 16b and 17b, respectively.

[0029] As in Fig. As shown in Figure 7, the printed circuit 12 has a first circuit group 14 and a second circuit group 15. The first circuit group 14 has a plurality of circuits 16 extending in the first direction X. The multiple circuits 16 are arranged in the second direction Y. The second circuit group 15 has a plurality of circuits 17 extending in the first direction X. The printed circuit 12 is designed such that a circuit 16 of the first circuit group 14 and a circuit 17 of the second circuit group 15 are alternately aligned.

[0030] Circuit 16 has a pattern 16a and a solder pad 16b located at one end of pattern 16a. Circuit 17 has a pattern 17a and a solder pad 17b located at one end of pattern 17a. The multiple solder pads 16b are aligned in a straight line along the second direction Y. The multiple solder pads 17b are also aligned in a straight line along the second direction Y. In the first direction X, the position of the solder pads 17b is offset relative to the position of the solder pads 16b. More precisely, the solder pads 17b project towards an edge 11a of the base sheet 11 relative to the solder pads 16b. Thus, pattern 17a runs between two adjacent solder pads 16b.

[0031] A through-hole 16c is formed in the solder pad 16b, into which the insert section 52 of the terminal 5 is inserted. The through-hole 16c penetrates the base film 11. Similarly, a through-hole 17c is formed in the solder pad 17b. The through-hole 17c also penetrates the base film 11. The through-holes 16c and 17c are arranged in a sawtooth zigzag pattern on the first flexible printed circuit board 10. As shown in Fig. As shown in Figure 6, the opening 13a in the cover layer 13 exposes the solder pad 16b of the first circuit group 14. The opening 13b exposes the solder pad 17b of the second circuit group 15.

[0032] The first flexible printed circuit board 10 is provided with two through-holes 10a and 10b. The two through-holes 10a and 10b are arranged on the section in the second direction Y, with the printed circuit 12 positioned between these through-holes. The through-hole 10a is aligned with the opening 13a and lies on an expansion direction in the second direction Y of the multiple solder pads 16b. The through-hole 10b is aligned with the opening 13b and is arranged on an expansion direction in the second direction Y of the multiple solder pads 17b. The support projection 47 of the first housing form 4A is inserted into one of the two through-holes 10a and 10b. The support projection 48 of the second housing 4B is inserted into the other of the two through-holes 10a and 10b.

[0033] The second flexible printed circuit board 20 has a similar configuration to the first flexible printed circuit board 10. As shown in Fig. As shown in Figure 8, the second flexible printed circuit board 20 has 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 solder pads 26b and 27b, respectively.

[0034] As in Fig. As shown in Figure 9, the printed circuit 22 has a first circuit group 24 and a second circuit group 25. The first circuit group 24 has a plurality of circuits 26 extending in the first direction X. The multiple circuits 26 are arranged in the second direction Y. The second circuit group 25 has a plurality of circuits 27 extending in the first direction X. The printed circuit 22 is designed such that a circuit 26 of the first circuit group 24 and a circuit 27 of the second circuit group 25 are alternately aligned.

[0035] Circuit 26 has a pattern 26a and a solder pad 26b located at an end section of pattern 26a. Circuit 27 has a pattern 27a and a solder pad 27b located at a section of pattern 27a. The multiple solder pads 26b and 27b are aligned in a straight line along the second direction Y. Solder pad 27b projects towards an edge 21a of the base foil 21 with respect to solder pad 26b. Pattern 27a runs between two adjacent solder pads 26b.

[0036] A through-hole 26c is formed in the solder pad 26b, into which the insert section 52 of the terminal 5 is inserted. A through-hole 27c is formed in the lance 27b. In other words, the through-holes 26c and 27c are arranged in a sawtooth zigzag pattern on the second flexible printed circuit board 20. As shown in Fig. As shown in Figure 8, the opening 23a in the cover layer 23 exposes the solder pad 26b of the first circuit group 24. The opening 23b exposes the solder pad 27b of the second circuit group 25.

[0037] The second flexible printed circuit board 20 is provided with two through-holes 20a and 20b. The two through-holes 20a and 20b are arranged at the end sections in the second direction Y, with the printed circuit 22 positioned between these through-holes. The through-hole 20a is aligned with the opening 23a and lies on an expansion direction in the second direction Y of the multiple solder pads 26b. The through-hole 20b is aligned with the opening 23b and is arranged on an expansion direction in the second direction Y of the multiple solder pads 27b. The support projection 47 of the first housing 4A is inserted into one of the two through-holes 20a and 20b. The support projection 48 of the second housing 4B is inserted into the other of the two through-holes 20a and 20b.

[0038] As in Fig. As shown in Figure 2, the cover 6 has a main body 61, a retaining section 62, and a hinged section 63. The cover 6 is, for example, made of an insulating resin. The main body 61 is a section that covers a connection between the flexible printed circuit boards 10 and 20 and the terminals 5 and engages with the outer housing 3. The retaining section 62 is a section that clamps and holds the flexible printed circuit boards 10 and 20 between the retaining section 62 and the main body 61. The hinged section 63 connects the main body 61 and the retaining section 62 and is flexible.

[0039] As in Fig. As shown in Figure 10, the main body 61 has a cover section 64, which covers the connection, and four foot sections 65. The cover section 64 has the form of a rectangular flat plate. The foot sections 65 are arranged at both end sections of the cover section 64 in the second direction Y. The foot section 65 is a section that engages the outer housing 3 and projects from the cover section 64 in the third direction Z. The foot section 65 is provided with an engagement recess 65a and an engagement projection 65b. The engagement recess 65a is formed on the inside of the foot section 65, facing the outer housing 3. The engagement recess 65a is provided on each of the four sections of the foot section 65. As shown in Fig. As shown in Figure 2, an engagement projection 34 is provided on the outside of the outer housing 3. The engagement recess 65a of the cover 6 engages in the engagement projection 34.

[0040] The engagement projection 65b engages in the retaining section 62 to lock the retaining section 62. The engagement projection 65b is provided on two adjacent foot sections 65.

[0041] The intervention projection 65b extends in the second direction Y from the outer surface, which is opposite the side on which the intervention recess 65a is located.

[0042] The retaining section 62 is aligned with the main body 61 in the second direction Y. The retaining section 62 has a first retaining section 62A and a second retaining section 62B. The first retaining section 62A and the second retaining section 62B are aligned in the first direction X. In a top view, the first retaining section 62A and the second retaining section 62B have a rectangular shape. A slot 66 is provided between the first retaining section 62A and the second retaining section 62B. This arrangement makes the first retaining section 62A and the second retaining section 62B independent of each other. The first retaining section 62A holds the first flexible printed circuit board 10. The second retaining section 62B holds the second flexible printed circuit board 20.

[0043] The hinge section 63 is arranged on the end section of the main body 61 opposite the side on which the engagement projection 65b is located. The hinge section 63 has a first hinge section 63A and a second hinge section 63B. The first hinge section 63A connects the first retaining section 62A to the main body 61, while the second hinge section 63B connects the second retaining section 62B to the main body 61. The hinge section 63 extends in the second direction Y from an end section of the cover section 64 in the second direction Y. The end sections of the first retaining section 62A and the second retaining section 62B are each provided with an engagement section 62c that engages with the engagement projection 65b.

[0044] The cover section 64 is provided with a rib 64a that restricts the bending shape of the flexible printed circuit boards 10 and 20. The rib 64a is located on a surface facing the retaining section 62 and extends in the second direction Y. The cross-sectional shape of the rib 64a is triangular. In other words, the cross-sectional shape of the rib 64a is tapered such that its width decreases in the first direction X towards the distal end in the projecting direction. The first retaining section 62A and the second retaining section 62B are provided with an inclined surface 62d corresponding to the rib 64a. The inclined surface 62d is located on the section adjacent to the slot 66. The rib 64a and the inclined surface 62d obtuse the bending angle of the flexible printed circuit boards 10 and 20.

[0045] The following describes the method for manufacturing the cable harness 1 according to the present embodiment. The method for manufacturing the cable harness comprises an operation for inserting the inner housing, an operation for inserting the connector, an operation for installing the flexible printed circuit board, an operation for connecting, an operation for attaching the cover, an operation for restricting the direction of the circuit board, and an operation for assembling the lever.

[0046] Fig. Figure 11 shows the insertion of the inner housing. In this process, the multiple stacked inner housings 4 are inserted into the outer housing 3. The first housing forms 4A and the second housing forms 4B are stacked alternately and inserted into the outer housing 3. The connector 2 shown has two first housing forms 4A and two second housing forms 4B. The multiple inner housings 4 are inserted into the housing section 31 along the third direction Z, guided by the rib 32d. The multiple inner housings 4 are held by the housing section 31. The inner housings 4 may have an engagement section that engages with the outer housing 3.

[0047] Fig. Figure 12 illustrates the process of inserting the connector. The multiple connectors 5 are inserted into the recess 45 of the first housing shape 4A and the recess 46 of the second housing shape 4B. The connecting section 51 of the connector 5 is inserted into the recesses 45 and 46. The inner housing 4 holds the connecting section 51 in place, with the insert section 52 of the connector 5 protruding from the recesses 45 and 46. This forms four rows of insert sections 52 oriented in the second direction Y. The four rows are oriented in the first direction X.

[0048] Fig. Figure 13 illustrates the process of installing the flexible printed circuit board. In this process, the insert section 52 of connector 5 is inserted into the first flexible printed circuit board 10 and the second flexible printed circuit board 20. More precisely, two rows of insert sections 52 are inserted into the first flexible printed circuit board 10, while the other two rows of insert sections 52 are inserted into the second flexible printed circuit board 20.

[0049] Insert section 52, corresponding to the first flexible printed circuit board 10, is inserted into solder pad 16b of the first circuit group 14 and into solder pad 17b of the second circuit group 15. Insert section 52, corresponding to the second flexible printed circuit board 20, is inserted into solder pad 26b of the first circuit group 24 and into solder pad 27b of the second circuit group 25. Furthermore, support projections 47 and 48 are inserted into the through-holes of the flexible printed circuit boards 10 and 20. As shown in Fig. As shown in Figure 14, the multiple terminals 5 comprise 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 circuit board 10. The first terminal group 5A has two rows of terminals 5 oriented along the second direction Y. The first terminal group 5A consists of terminals arranged on a first side X1 beneath the multiple terminals 5 of the connector 2. The second terminal group 5B is a group of terminals 5 connected to the second flexible printed circuit board 20. The second terminal group 5B has two rows of terminals 5 oriented along the second direction Y. The second terminal group 5B is formed from terminals arranged on a second side X2 beneath the multiple terminals 5 of the connector 2.

[0050] The first flexible printed circuit board 10 has solder pads 16b and 17b, which are connected to the insert sections 52 of the first terminal group 5A. As in Fig. As shown in Figure 7, solder pads 16b and 17b each have through holes 16c and 17c. The insert section 52 of the first terminal group 5A is inserted into the through holes 16c and 17c. As shown in Fig. As shown in Figure 14, one series of the insert sections 52 of the first connection group 5A is inserted into the solder lug 16b, and the other series of insert sections 52 is inserted into the solder lug 17b.

[0051] The second flexible printed circuit board 20 has solder pads 26b and 27b, which are connected to the insert section 52 of the second terminal group 5B. As shown in Fig. As shown in Figure 9, the solder pads 26b and 27b have the through holes 26c and 27c, respectively. The insert section 52 of the second connection group 5B is inserted into the through holes 26c and 27c. As shown in Fig. As shown in Figure 14, one row of the terminal group 52 of the second terminal group 5B is inserted into the solder lug 26b, and the other row of the terminal group 52 is inserted into the solder lug 27b.

[0052] The connection process is the process of connecting the insert section 52 of the terminals 5 to the solder pads 16b, 17b, 26b, and 27b. In the cable harness 1 of the present embodiment, the insert section 52 is soldered to the solder pads 16b, 17b, 26b, and 27b. Solder paste can be applied to the solder pads 16b, 17b, 26b, and 27b beforehand. In this case, soldering can be carried out during the joining process by irradiating the solder paste with laser light. For example, all solder pads 16b, 17b, 26b, and 27b can be connected to the insert sections 52 in a single irradiation process. However, the soldering technique is not limited to irradiation with laser light and can instead be carried out with a reflow oven or another suitable technique.

[0053] The printed circuit 12 of the first flexible printed circuit board 10 extends from the first terminal group 5A towards the first side X1. The printed circuit 22 of the second flexible printed circuit board 20 extends from the second terminal group 5B towards the second side X2. In the Fig. In the wiring harness shown in Figure 14, the first side X1 is the one side in the first direction X, and the second side X2 is the other side in the first direction X. In other words, the two printed circuits 12 and 22 extend in opposite directions to each other.

[0054] When attaching the cover, as described in Fig. As shown in Figure 15, the main body 61 of the cover 6 is attached to the outer housing 3. The cover section 64 of the main body 61 covers and protects the connection between the flexible printed circuit boards 10 and 20 and the terminals 5. In other words, the cover section 64 covers and protects the insert section 52 of the terminal 5 and the solder pads 16b, 17b, 26b, and 27b of the flexible printed circuit boards 10 and 20. When the main body 61 is assembled with the outer housing 3, the retaining section 62 is positioned at a position offset in the second direction Y relative to the flexible printed circuit boards 10 and 20.

[0055] The process of restricting the direction of the printed circuit board involves a process of bending the printed circuit board and a process of locking the printed circuit board. Fig. Figure 16 is a diagram describing the process of bending the printed circuit board (PCB). During PCB bending, the first flexible printed circuit board 10 and the second flexible printed circuit board 20 are bent so that they overlap each other. The two flexible printed circuit boards 10 and 20 are bent to enclose the cover section 64 and overlap the cover layers 13 and 23, which are opposite each other. In other words, the two flexible printed circuit boards 10 and 20 are bent in a U-shape by 180° along the cover section 64.

[0056] Fig. Figure 17 is a diagram describing the process of locking the printed circuit board. During locking, the two flexible printed circuit boards 10 and 20 are held in place by the retaining section 62 of the cover 6. The cover 6 of the present embodiment holds the two flexible printed circuit boards 10 and 20 in an overlapping arrangement.

[0057] The first retaining section 62A engages the main body 61 while bending the first hinge section 63A. The first retaining section 62A clamps the first flexible printed circuit board 10 between the first retaining section 62A and the main body 61. The second retaining section 62B engages the main body 61 while bending the second hinge section 63B. The second retaining section 62B clamps the second flexible printed circuit board 20 between the second retaining section 62B and the main body 61. The two flexible printed circuit boards 10 and 20 are pulled outwards through the slot 66 between the first retaining section 62A and the second retaining section 62B.

[0058] Slot 66 is used as an exit section to extend the overlapping flexible printed circuit boards 10 and 20. The extension direction of the flexible printed circuit boards 10 and 20 is the third direction Z. More precisely, the flexible printed circuit boards 10 and 20 extend from the retaining section 62 along the third direction Z towards the side opposite the outer housing 3. In other words, the flexible printed circuit boards 10 and 20 extend from the retaining section 62 in the direction in which the insert section 52 of the connector 5 protrudes from the inner housing 4.

[0059] Fig. Figure 18 illustrates the bending shape of the flexible printed circuit boards 10 and 20. As in Fig. As shown in Figure 18, the first flexible printed circuit board 10 is held by the cover 6 by a first curved section 10c, a second curved section 10d, and a third curved section 10e. The first curved section 10c is U-shaped along the cover part 64. The second curved section 10d is formed in a section where the rib 64a of the cover part 64 rises. The third curved section 10e is formed at the distal end of the rib 64a. The gap between the cover part 64 and the first holding section 62A is curved to form the second curved section 10d and the third curved section 10e on the first flexible printed circuit board 10. The interior angles of the first curved section 10c and the second curved section 10d are obtuse angles.

[0060] The second flexible printed circuit board 20 is held by the cover 6, which has a first curved section 20c, a second curved section 20d, and a third curved section 20e. The first curved section 20c is U-shaped along the cover part 64. The first two curved sections 10c and 20c are curved towards opposite sides. In other words, the first curved section 10c of the first flexible printed circuit board 10 has a curved shape that is convex towards the first side X1. On the other hand, the first curved section 20c of the second flexible printed circuit board 20 has a curved shape that is convex towards the second side X2. The second curved section 20d is formed in the section where the rib 64a rises. The third curved section 20e is formed at the distal end of rib 64a.The interior angles of the second curved section 20d and the third curved section 20e are obtuse.

[0061] The two flexible printed circuit boards 10 and 20 overlap at the third curved sections 10e and 20e and extend in the third direction Z. The cover 6 of the present embodiment is designed to prevent excessive bending of the flexible printed circuit boards 10 and 20. For example, in the cover part 64, the corners corresponding to the first curved sections 10c and 20c are chamfered in an arc. Furthermore, the sections forming the second curved sections 10d and 20d and the third curved sections 10e and 20e are bent at an angle greater than a right angle. Thus, the cover 6 of the present embodiment can limit the path of the flexible printed circuit boards 10 and 20 without causing excessive bending in the flexible printed circuit boards 10 and 20.

[0062] In this way, the cover 6 of the present embodiment not only protects the connection between the flexible printed circuit boards 10 and 20 and the connectors 5, but also limits the path of the flexible printed circuit boards 10 and 20. The cover 6 causes the two flexible printed circuit boards 10 and 20 to overlap and expand. This overlap facilitates the handling of the connector 2. The two flexible printed circuit boards 10 and 20 are connected to the devices via a connector or similar device. The two flexible printed circuit boards 10 and 20 can be connected to the same device or to different devices.

[0063] Fig. Figure 19 shows the connector 2 to which the lever 7 is attached. During assembly, the lever 7 is attached to the outer housing 3. The connector 2, to which the lever 7 is attached, is joined with the mating connector 100. The lever 7 amplifies the force applied to it and transmits the force to the mating connector 100, thereby inserting the mating connector 100 into the outer housing 3.

[0064] As described above, the cable harness 1 of the present embodiment comprises the connector 2, the first flexible printed circuit board 10, the second flexible printed circuit board 20, and the cover 6, which serves as a retaining element. The connector 2 has multiple terminals 5, each of which has a rod-shaped or tubular insert section 52, and housings 3 and 4 configured to retain the multiple terminals 5, which are arranged in multiple rows with the insert section 52 protruding. The multiple rows are oriented in the first direction X. The multiple terminals 5 have the first terminal group 5A, which is arranged on the first side X1 of the first direction X, and the second terminal group 5B, which is arranged on the second side X2 of the first direction X.The first flexible printed circuit board 10 includes the through-holes 16c and 17c into which the insert section 52 of the first terminal group 5A is inserted, and includes the printed circuit 12, which is connected to the insert section 52 of the first terminal. The second flexible printed circuit board 20 includes the through-holes 26c and 27c into which the insert section 52 of the second terminal group 5B is inserted, and includes the printed circuit board 22, which is connected to the insert section 52 of the second terminal group 5B. The cover 6, which acts as a retaining element, is attached to the housings 3 and 4 and secures the first flexible printed circuit board 10 and the second flexible printed circuit board 20.

[0065] The cover 6 has an exit section to allow the first flexible printed circuit board 10 and the second flexible printed circuit board 20, which overlap each other, to extend from the exit section. The exit section of the cover 6 is, for example, the slot 66. In the cable harness 1 of the present embodiment, the two flexible printed circuit boards 10 and 20 overlap and are extended by the retaining element. In this way, the cable harness 1 of the present embodiment is able to improve its handling. For example, by bundling the two flexible printed circuit boards 10 and 20 together, the cable harness 1 can be easily handled during transport and routing. The two overlapping flexible printed circuit boards 10 and 20 can be routed on the same routing path or on different routing paths.the path branches out.

[0066] The cover 6 of the present embodiment holds the first flexible printed circuit board 10 and the second flexible printed circuit board 20 in their respective bent states and causes the first flexible printed circuit board 10 and the second flexible printed circuit board 20, which overlap each other, to extend from the exit section into the projecting direction of the insert section 52. Such a configuration is used, for example, when the flexible printed circuit boards 10 and 20 are positioned along the projecting direction of the insert section 52.

[0067] The cover 6 of the present embodiment comprises the main body 61, which is attached to the housings 3 and 4 such that it covers the insert section 52, the retaining section 62, and the hinge section 63, which connects the main body 61 and the retaining section 62. The cover 6 causes the first flexible printed circuit board 10 and the second flexible printed circuit board 20 to overlap by clamping them between the main body 61 and the retaining section 62. The cover 6 of the present embodiment not only holds the flexible printed circuit boards 10 and 20 in place but also protects the connection between the insert section 52 and the flexible printed circuit boards 10 and 20.

[0068] The cover 6 of the present embodiment comprises the main body 61, which is attached to the housings 3 and 4 to cover the insert section 52, the first retaining section 62A, the first hinge section 63A connecting the main body 61 and the first retaining section 62A, the second retaining section 62B, and the second hinge section 63B connecting the main body 61 and the second retaining section 62B. The cover 6 clamps the first flexible printed circuit board 10 between the main body 61 and the first retaining section 62A, clamps the second flexible printed circuit board 20 between the main body 61 and the second retaining section 62B, and causes the overlapping first flexible printed circuit board 10 and the second flexible printed circuit board 20 to protrude from the slot 66. The slot 66 is a gap between the first retaining section 62A and the second retaining section 62B.The first holding section 62A and the second holding section 62B are independent of each other, which makes it easier to secure the flexible printed circuit boards 10 and 20.

[0069] Furthermore, the number of inner housings 4 that the connector 2 has is not limited to four. For example, the first recess 45 and the second recess 46 can be provided in the first housing shape 4A, and the first recess 45 and the second recess 46 can be provided in the second housing shape 4B. In this case, the number of inner housings 4 that the connector 2 has can be two.

[0070] The housing of connector 2 is not necessarily divided into outer housing 3 and inner housing 4. For example, the outer housing 3 may be provided with recesses 45 and 46. Connector 2 is not limited to a lever-type connector with lever 7.

[0071] The cover 6 can be designed such that the main body 61 and the retaining section 62 are not integral. For example, the main body 61 and the retaining section 62 can be separate components. In this case, the main body 61 is first attached to the outer housing 3. Then, as shown in Fig. Figure 16 shows the retaining section 62, which is a separate component to which the main body 61 or the outer housing 3 is attached, while the flexible printed circuit boards 10 and 20 are bent. [First modification of the embodiment]

[0072] A first modification of the present embodiment will now be described. Fig. Figure 20 is a diagram illustrating a process of bending a wiring plate according to the first modification of an embodiment, Fig. Figure 21 is a diagram illustrating a process of locking the wiring plate according to the first modification of the embodiment, Fig. 22 to Fig. Figure 24 are diagrams illustrating a process of assembling a lever according to the first modification of the embodiment. Fig. Figure 25 is a diagram illustrating a process of assembly according to the first modification of the embodiment, Fig. Figure 26 is a perspective view illustrating a cable harness fully connected to a mating connector. Fig. Figure 27 is a side view illustrating the wiring harness fully connected to the mating connector. Fig. 28 is a side view illustrating the cable harness fully connected to the mating connector, Fig. Figure 29 is a diagram illustrating a process of bending the printed circuit board according to the first modification of the embodiment, and Fig. Figure 30 is a diagram illustrating a process for locking the printed circuit board according to the first modification of the embodiment. In the first modification of the embodiment, a difference from the embodiment described above is, for example, that flexible printed circuit boards 10 and 20 extend in a first direction X.

[0073] The direction in which the two flexible printed circuit boards 10 and 20 extend from the cover 6 can be the first direction X. As shown in Fig. As shown in Figure 20, the flexible printed circuit boards 10 and 20 can, for example, be pulled out from the cover 6 to a second side X2 in the first direction X. In this case, when bending the circuit boards, the operator bends the first flexible printed circuit board 10 and overlaps the first flexible printed circuit board 10 with the second flexible printed circuit board 20, as shown in Figure 20. Fig. 20 is shown. The first flexible printed circuit board 10 is bent back so that it is wrapped around the cover section 64 of the cover 6 and overlaps with the second flexible printed circuit board 20.

[0074] The process of locking the wiring board is then carried out. During this process, the operator engages the first holding section 62A and the second holding section 62B with a main body 61 while bending the hinge sections 63A and 63B. This causes the first flexible printed circuit board 10 to be clamped and held between the two holding sections 62A and 62B and the cover section 64.

[0075] The lever assembly process is then carried out. During assembly, the operator bends the two flexible printed circuit boards 10 and 20 so that they are aligned with a side surface 62f of the second retaining section 62B, as shown in Fig. 22 and Fig. Figure 23 shows that the flexible printed circuit boards 10 and 20 are bent in a third direction Z towards the side opposite an outer housing 3. As shown in Fig. As shown in Figure 23, the two flexible printed circuit boards 10 and 20 are pulled out of an end section 67 of the cover 6. In other words, the cover section 67 of the cover 6 on the second side X2 is used as the exit section for the flexible printed circuit boards 10 and 20. More precisely, the first flexible printed circuit board 10 extends outward from the cover 6 through a gap between the cover section 64 and the second retaining section 62B. The second flexible printed circuit board 20 extends outward from the cover 6 through a gap between the cover section 64 and the outer housing 3.

[0076] Then, as in Fig. Figure 24 shows a lever 7 attached to the outer housing 3. The lever 7 has a pair of arms 71 and an actuating section 72. The pair of arms 71 has a plate-like shape and faces each other in the first direction X. The actuating section 72 is a section onto which the actuating force is applied by an operator. The actuating section 72 connects the pair of arms 71 and extends in the first direction X.

[0077] The arm 71 is provided with a guide hole 71a and a stop section 71b. The guide hole 71a is an arc-shaped hole into which the shaft section 32c of the outer housing 3 is inserted. The inner wall of the housing 110 of the mating connector 100 is provided with a support section for receiving the engagement section 71b. The stop section 71b abuts the support section of the mating connector 100 and is engaged by the support section. The lever 7 rotates about the engaging stop section 71b as its pivot point, thereby connecting the outer housing 3 to the housing 110.

[0078] As in Fig. As shown in Figure 24, the lever 7 is attached to the outer housing 3 such that the arm 71 is positioned outwards relative to the two overlapping flexible printed circuit boards 10 and 20. Thus, the flexible printed circuit boards 10 and 20 extend in the third direction Z through a gap between the arm 71 and the cover 6.

[0079] As in Fig. As shown in Figure 25, the outer housing 3 is inserted into the housing 110 of the mating connector 100 along the third direction Z. After inserting the outer housing 3 to the half-inserted position, the operator presses on the housing section 72 indicated by arrow AR1 to rotate the lever 7. The pressure applied by the operator is transmitted to the outer housing 3 via a force multiplication mechanism, thereby fully engaging the outer housing 3 with the housing 110.

[0080] Fig. 26 and Fig. Figure 27 shows connector 2 in full engagement with the mating connector 100. After complete assembly, most of the arm 71 of lever 7 is housed in the casing 110. More precisely, as shown in Fig. As shown in Figure 27, the arm 71 is housed within the casing 110 so that it does not overlap the casing section 62 when viewed from the first direction X. As shown in Fig. As shown in Figure 27, the gap between the second retaining section 62B and the cover section 64 is open towards the second side X2. Thus, according to the first modification of the embodiment, the cover 6 allows the first flexible printed circuit board 10 to extend linearly towards the second side X2. The second flexible printed circuit board 20 is extended towards the second side X2 so that it extends over the arm 71. More precisely, the second flexible printed circuit board 20 has a first section 20f extending in the third direction Z and a second section 20g extending in the first direction X. The first section 20f is formed in the gap between the arm 71 and the outer housing 3.The second flexible printed circuit board 20 is bent so that it follows the first flexible printed circuit board 10 at the point where the first section 20f intersects with the first flexible printed circuit board 10. This allows the second flexible printed circuit board 20 to overlap the first flexible printed circuit board 10. In other words, the complete connection of connector 2 with the mating connector 100 enables a linear extension of the flexible printed circuit boards 10 and 20 towards the second side X2.

[0081] In this way, connector 2 is configured so that the expansion direction of the two flexible printed circuit boards 10 and 20 can be adjusted in the first direction X. This allows the cable harness 1 to flexibly adapt to different routing directions when installed in a vehicle.

[0082] Furthermore, connector 2, as shown in Fig. As shown in Figure 28, the flexible printed circuit boards 10 and 20 can also be configured so that they extend from the cover 6 towards the first side X1. In this case, as shown in Fig. As shown in Figure 29, when bending the circuit board, the operator bends the second flexible printed circuit board 20 and overlaps it with the first flexible printed circuit board 10. The second flexible printed circuit board 20 is bent back to wrap around the cover part 64 of the cover 6 and overlap the first flexible printed circuit board 10.

[0083] During the locking of the circuit board, the second flexible printed circuit board 20 is clamped and held between the two retaining sections 62A and 62B and the cover section 64. Subsequently, during the assembly of the lever, the two flexible printed circuit boards 10 and 20 are bent so that they are flush with a side surface 62e of the first retaining section 62A, and the lever 7 is attached to the outer housing 3. The connector 2 is then fully joined to the mating connector 100, as shown in Fig. As shown in Figure 28, it allows the overlapping flexible printed circuit boards 10 and 20 to be extended linearly in the direction of the first side X1. [Second modification of the embodiment]

[0084] A second modification of the present embodiment is now described. Fig. Figure 31 is a cross-sectional view of a cable harness according to the second modification of the embodiment. The second modification of the present embodiment differs from the previously mentioned embodiments, for example, in the orientation of the attachment of the flexible printed circuit boards 10 and 20 to a terminal 5. The in Fig. The first flexible printed circuit board 10 shown in Figure 31 is connected to the first terminal group 5A such that it extends from the first terminal group 5A to the second side X2. The second flexible printed circuit board 20 is connected to the second terminal group 5B such that it extends from the second terminal group 5B to the first side X1.

[0085] The two flexible printed circuit boards 10 and 20 are bent in the third direction Z and overlap at a position between the first terminal group 5A and the second terminal group 5B. The connector 2 of the second modification can have a retaining element that is attached to the outer housing 3 to cause the two flexible printed circuit boards 10 and 20 to extend in the third direction Z.

[0086] Connector 2 can be configured as a shielded connector. In this case, a conductive shielding layer can be provided in the first flexible printed circuit board 10 and the second flexible printed circuit board 20. Since the two flexible printed circuit boards 10 and 20 overlap, the shielding layer is located on the outside. The shielding layer can be a conductive paste applied to the outer surface of the base films 11 and 21.

[0087] In the case where connector 2 is configured as a shielded connector, connector 2 may have a conductive section that grounds the shielding layer. The conductive section for grounding may ground the shielding layer of the flexible printed circuit boards 10 and 20 to a metallic housing or the like. The conductive section for grounding may be a conductive element provided in the outer housing 3 or a shielding sleeve covering the outer housing 3.

[0088] The disclosures set forth in the aforementioned embodiments and modifications can be implemented in suitable combinations.
