[0010] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described. Any combination of the following multiple embodiments within a range that does not cause contradictions is also included in the description of the present invention.

[0011] The wiring module of the first disclosure includes: (1) A connector includes a flexible printed circuit board and a connector mounted on the flexible printed circuit board. The connector has a housing and a plurality of terminal fittings fixed to the flexible printed circuit board by soldering while attached to the housing. The housing is integrally provided with an attachment portion that is directly attached to a target component to which the connector is attached. According to the first disclosure, the mating resistance force that the housing experiences during the mating process between the connector and a mating connector acts on the target component via the attachment portion, but does not act on the flexible printed circuit board. Therefore, cracks can be prevented from occurring in the soldered portions that fix the terminal fittings to the flexible printed circuit board.

[0012] (2) In (1), the mounting portion is preferably disposed on an outer surface of the housing opposite to the facing surface facing the flexible printed circuit board. This configuration makes it possible to prevent the flexible printed circuit board from interfering with the mounting portion or the mounting target component.

[0013] (3) In (1) or (2), the terminal fittings have board connection portions that are exposed to the outside of the housing and connected to the flexible printed circuit board by the soldering. The housing is configured by assembling a terminal holding member that holds the terminal fittings and a cover that is a separate part from the terminal holding member and covers the board connection portions. It is preferable that the attachment portion is provided on the cover. With this configuration, the cover can prevent short circuits between the board connection portions. Since the cover has both the function of preventing short circuits between the board connection portions and the function of attachment to the attachment target member, the shape of the housing can be simplified compared to when the attachment portion is integrally formed with the housing.

[0014] (4) In (3), it is preferable that the mounting portion is a separate part from the cover. With this configuration, the mounting portion can be changed depending on the shape of the mounting target component, so that the cover can be used in common for mounting target components of different shapes.

[0015] (5) In (3), it is preferable that the mounting portion is formed integrally with the cover. With this configuration, the number of parts constituting the connector can be reduced compared to when the mounting portion is a separate part from the cover.

[0016] (6) In (1) or (2), it is preferable that the mounting portion is formed integrally with the housing. With this configuration, the number of parts constituting the connector can be reduced compared to when the mounting portion is a separate part from the housing.

[0017] The wiring module mounting device of the second disclosure is (7) A wiring module is provided, in which a connector is mounted on a flexible printed circuit board, and an attachment member to which the wiring module is attached. The connector has a housing and a plurality of terminal fittings that are fixed to the flexible printed circuit board by soldering while attached to the housing. The housing is integrally provided with an attachment portion that is directly attached to the attachment member. According to the second disclosure, as with the first disclosure, it is possible to prevent cracks from occurring in the soldered portions that fix the terminal fittings to the flexible printed circuit board.

[0018] [Details of the embodiments of the present disclosure] [Example 1] A first embodiment of the present disclosure will be described with reference to Figures 1 to 4. The present invention is not limited to these examples, but is defined by the claims, and includes all modifications within the meaning and scope of the claims. In this first embodiment, with regard to the front-to-back direction, the F direction in Figures 1 to 3 is defined as the front. With regard to the up-down direction, the H direction in Figures 1 to 4 is defined as the up. With regard to the left-to-right direction, the R direction in Figures 1, 2, and 4 is defined as the right. The left-to-right direction and the width direction are used synonymously.

[0019] The mounting device A for the wiring module 10 of the first embodiment is a device for mounting the wiring module 10 to a mounting target member 57. The wiring module 10 has a flexible printed circuit board 11 (FPC), which is a type of circuit board, and a connector 15 mounted on a mounting surface 12 of the flexible printed circuit board 11. The structure of the mounting device A will be described below in a state in which the flexible printed circuit board 11 is placed horizontally with the mounting surface 12 facing upward. A reinforcing plate 13 is fixed to the underside of the flexible printed circuit board 11 in an area where the connector 15 is mounted, in order to increase the rigidity of the flexible printed circuit board 11 and suppress bending deformation.

[0020] The attachment target member 57 is a horizontal plate-like member. Specifically, it is a support member for supporting a bus bar in a battery pack of a secondary battery (not shown), the body of an automobile, etc. The attachment target member 57 has a circular attachment hole 58 formed therein, which penetrates the attachment target member 57 in the vertical direction (plate thickness direction).

[0021] The connector 15 has a housing 16 made of synthetic resin and a plurality of terminal fittings 50. The housing 16 has a terminal holding member 17, which is a single component, a synthetic resin cover 27, which is also a single component, and a clip 40, which is also a single component. The lower surface of the terminal holding member 17 is defined as an opposing surface 18 that faces the mounting surface 12 of the flexible printed circuit board 11. Metal pegs 20, with their thicknesses facing the left-right direction, are fixed to the lower end regions of both left and right outer surfaces 19 of the terminal holding member 17. The pair of left and right pegs 20 are fixed to the mounting surface 12 of the flexible printed circuit board 11 by soldering.

[0022] A plurality of terminal accommodating chambers 21 are formed inside the terminal holding member 17, penetrating the terminal holding member 17 in the front-to-rear direction. Protrusions 26 are formed at the front ends of both left and right outer surfaces 19 of the terminal holding member 17. Fitting holes 22 are formed in the protrusions 26, penetrating the protrusions 26 in the front-to-rear direction. A pair of left and right protective wall portions 23 are formed at the rear end of the terminal holding member 17, protruding rearward from both left and right edge portions. Anti-pullout protrusions 24 are formed on the outer wall surfaces at the rear ends of the protective wall portions 23. A fitting groove 25 is formed in the inner wall surface at the rear end of the protective wall portions 23, extending in the front-to-rear direction.

[0023] The cover 27 has an upper wall 28, a pair of outer wall portions 29 protruding downward from the left and right side edges of the upper wall 28, a pair of inner wall portions 30 protruding downward from the rear end of the upper wall 28, and a rear wall portion 31 protruding downward from the rear end edge of the upper wall 28. The rear end edge of the outer wall portion 29 and the side edge of the rear wall portion 31 are joined at a right angle to each other. The rear end edge of the inner wall portion 30 and the side edge of the rear wall portion 31 are joined at a right angle to each other. The upper surface of the upper wall 28 is defined as an opposing surface 32 that faces in the vertically opposite direction from the opposing surface 18. The opposing surface 32 is formed with a fixed-side locking protrusion 33 and a pair of left and right guide grooves 34. A forward-protruding mating protrusion 35 is formed at the front end of each of the left and right outer wall portions 29. A mating rib 36 extending in the front-to-rear direction is formed at the rear end of each of the left and right inner wall portions 30.

[0024] A plurality of notches 37 are formed in the lower end of the rear wall 31. The multiple notches 37 are arranged side by side at intervals in the left-right direction. Each notch 37 is open on both the front and rear surfaces and the bottom surface of the rear wall 31. Each notch 37 is designed to accommodate the rear end of a mounting portion 55 of a terminal fitting 50, which will be described later. A plurality of partition walls 38, with their wall thickness oriented in the left-right direction, are formed inside the cover 27. The partition walls 38 are connected to the bottom surface of the upper wall 28 and the front surface of the rear wall 31, and are arranged in parallel at intervals in the left-right direction.

[0025] The housing 16 is formed by attaching the cover 27 to the terminal holding member 17. The upper wall 28 of the cover 27 is disposed to cover the upper surface of the terminal holding member 17 from above. The outer wall 29 and the inner wall 30 are disposed to cover the outer surface 19 of the terminal holding member 17. The rear wall 31 is disposed to cover the rear surface of the terminal holding member 17 from behind. When the cover 27 is attached to the terminal holding member 17, the fitting protrusions 35 fit into the fitting holes 22 from behind, thereby restricting vertical and horizontal displacement of the cover 27 relative to the terminal holding member 17. Furthermore, the fitting ribs 36 fit into the fitting grooves 25 from behind, thereby restricting vertical displacement of the cover 27 relative to the terminal holding member 17. Furthermore, the locking portions (not shown) of the cover 27 engage with the retaining protrusions 24, thereby restricting rearward displacement of the cover 27 relative to the terminal holding member 17.

[0026] The clip 40 is made of a synthetic resin material. The clip 40 is a single member that integrates a connecting portion 41 and an attachment portion 45. A pair of guide ribs 42 extending in the front-rear direction are formed on both left and right side edges of the connecting portion 41. A lock arm 43 that is elastically deformable in the vertical direction is formed on the underside of the connecting portion 41. A movable-side lock protrusion 44 is formed on the underside of the lock arm 43. The attachment portion 45 has a base 46, a flange 47, and a pair of symmetrical elastic retaining pieces 48. The base 46 protrudes upward from the top surface of the connecting portion 41. The flange 47 protrudes radially outward from the outer periphery of the lower end of the base 46. In a plan view of the clip 40 from above, the flange 47 is circular. The pair of elastic retaining pieces 48 extend diagonally downward in a cantilevered manner from the upper end of the base 46. The pair of elastic retaining pieces 48 are capable of elastic deformation in the radial direction (left and right direction).

[0027] The clip 40 is assembled by sliding it from rear to front relative to the opposing surface 32 of the cover 27. During assembly, the pair of guide ribs 42 are fitted into the pair of guide grooves 34. During the assembly process, the movable-side locking protrusion 44 of the locking arm 43 interferes with the fixed-side locking protrusion 33 of the cover 27, causing the locking arm 43 to elastically deform upward. When the clip 40 is attached to the cover 27, the movable-side locking protrusion 44 engages with the fixed-side locking protrusion 33, thereby holding the clip 40 in a state where it is prevented from being removed from the cover 27. When the clip 40 is assembled to the cover 27, the mounting portion 45 of the clip 40 is disposed on the opposing surface 32 (top surface) of the housing 16.

[0028] The terminal fitting 50 is a single component having a terminal body 51 and a board connecting portion 52. The terminal body 51 has a rectangular cylindrical shape that is elongated in the front-to-rear direction. A resilient contact piece (not shown) is housed within the terminal body 51. When the connector 15 is mated with a mating connector (not shown), a tab of a male terminal (not shown) provided on the mating connector is inserted into the terminal body 51, and the resilient contact piece resiliently contacts the tab. The terminal body 51 is housed within the terminal accommodating chamber 21.

[0029] The board connection portion 52 is a narrow, elongated portion extending rearward in a cantilevered manner from the rear end of the terminal body 51. The board connection portion 52 has a horizontal portion 53 extending rearward from the rear end of the lower surface of the terminal body 51, leg portions 54 extending downward from the rear end of the horizontal portion 53, and mounting portions 55 extending rearward from the lower ends of the leg portions 54. Most of the board connection portion 52, excluding the front end of the horizontal portion 53, protrudes rearward from the terminal holding member 17 and is sandwiched between a pair of protective walls 23. The board connection portion 52 is exposed to the outside of the terminal holding member 17 and is housed within the cover 27. Adjacent board connection portions 52 in the left-right direction are separated by a partition wall 38 of the cover 27. The rear end of each mounting portion 55 is individually housed in one of the multiple cutouts 37.

[0030] The connector 15 is configured by attaching the terminal fittings 50 and the cover 27 to the terminal holding member 17 and then attaching the clip 40 to the cover 27. The connector 15 is mounted on the flexible printed circuit board 11 by soldering. Specifically, the housing 16 (terminal holding member 17) is fixed to the flexible printed circuit board 11 by soldering the pegs 20 to the mounting surface 12. The mounting portion 55 of each terminal fitting 50 is soldered to the flexible printed circuit board 11 so as to be conductive. The flexible printed circuit board 11 does not have a through-hole, and the mounting portion 55 is surface-mounted to the mounting surface 12. The lower edge of the rear wall portion 31 of the cover 27 is located close to the mounting surface 12 of the flexible printed circuit board 11 so as to face the mounting surface 12 in a non-contact state. The outer wall portion 29 and the inner wall portion 30 are kept in a non-contact state with the flexible printed circuit board 11. The wiring module 10 is configured by mounting the connector 15 on the flexible printed circuit board 11.

[0031] The wiring module 10 is attached to the attachment target member 57 by the attachment portions 45 of the clip 40. When attaching the clip 40 to the attachment target member 57, the attachment portions 45 of the clip 40 are fitted into the attachment hole 58 from below the attachment target member 57. During the fitting process, the pair of elastic retaining pieces 48 elastically deform as they interfere with the opening edges of the attachment hole 58. The flange portions 47 abut against the underside of the attachment target member 57 and elastically deform. When the elastic retaining pieces 48 pass through the through holes, the elastic retaining pieces 48 elastically return radially outward and engage with the opening edges of the attachment hole 58 on the upper surface of the attachment target member 57. The attachment target member 57 is clamped between the flange portions 47 and the elastic restoring force, thereby attaching the wiring module 10 to the attachment target member 57.

[0032] When the wiring module 10 is attached to the attachment target member 57, the flexible printed circuit board 11 does not come into contact with the attachment target member 57. Only the housing 16 (clip 40) of the wiring module 10 directly abuts against the attachment target member 57. Therefore, the mating resistance acting on the connector 15 during the mating process between the connector 15 and the mating connector acts on the attachment target member 57 via the attachment portion 45 of the clip 40, but does not act on the soldered portion between the flexible printed circuit board 11 and the mounting portion 55 of the terminal fitting 50.

[0033] The mounting device A for the wiring module 10 of the first embodiment includes the wiring module 10 in the form of a flexible printed circuit board 11 on which a connector 15 is mounted, and an attachment target member 57 to which the wiring module 10 is attached. The connector 15 has a housing 16 and a plurality of terminal fittings 50. The housing 16 is integrally provided with an attachment portion 45 that is attached directly to the attachment target member 57. The terminal fittings 50 are fixed to the flexible printed circuit board 11 by soldering while attached to the housing 16. The mounting device A and the wiring module 10 of the first embodiment can prevent cracks from occurring in the soldered portions that fix the terminal fittings 50 and the flexible printed circuit board 11.

[0034] The attachment portion 45 is disposed on an opposing surface 32 of the outer surface of the housing 16, the opposing surface 32 facing the opposite side to the opposing surface 18 that faces the flexible printed circuit board 11. With this configuration, it is possible to prevent the flexible printed circuit board 11 from interfering with the attachment portion 45 or the attachment target member 57.

[0035] The terminal fittings 50 have board connection portions 52 that are exposed outside the housing 16 and connected to the flexible printed circuit board 11 by soldering. The housing 16 is configured by assembling a terminal holding member 17 that holds the terminal fittings 50 and a cover 27 that is a separate component from the terminal holding member 17 and covers the board connection portions 52. The attachment portions 45 are provided on the cover 27. With this configuration, the cover 27 can prevent foreign objects from coming into contact with the board connection portions 52, thereby preventing short-circuiting between the board connection portions 52 due to contact with foreign objects. The cover 27 has both the function of preventing short-circuiting of the board connection portions 52 and the function of attaching the connector 15 to the attachment target member 57. Therefore, the shape of the housing 16 can be simplified compared to when the attachment portions 45 are integrally formed with the housing 16.

[0036] The mounting portion 45 is a separate component from the cover 27. With this configuration, the mounting portion 45 can be changed depending on the shape of the mounting target member 57, and therefore the cover 27 can be made standardized for mounting target members 57 of different shapes.

[0037] [Example 2] A second embodiment of the present disclosure will be described with reference to Figures 5 to 7. In this second embodiment, with regard to the front-to-rear direction, the F direction in Figures 5 to 7 is defined as the front. With regard to the up-down direction, the H direction in Figures 5 to 7 is defined as the up. With regard to the left-to-right direction, the R direction in Figures 5 and 6 is defined as the right. The left-to-right direction and the width direction are used synonymously. An attachment device B for a wiring module 60 in this second embodiment has a different structure for the connector 61 than that of the first embodiment. Since the other configurations are the same as those of the first embodiment, the same components are denoted by the same reference numerals, and descriptions of the structure, operation, and effect will be omitted.

[0038] A wiring module 60 of the second embodiment includes the same flexible printed circuit board 11 as in the first embodiment, and a connector 61 mounted on the flexible printed circuit board 11. The connector 61 includes a housing 62 and a plurality of terminal fittings 50, which are the same components as in the first embodiment. The housing 62 is integrally provided with an attachment portion that is attached directly to an attachment target member 57 to which the connector 61 is attached.

[0039] The housing 62 is configured by assembling the terminal holding member 17, which is the same part as in the first embodiment, and a multi-function member 63, which is a single part. The multi-function member 63 has a cover function part 64 having the same function as the cover 27 of the first embodiment, and an attachment function part 65 having the same function as the clip 40 of the first embodiment. The cover function part 64 has the same configuration as the cover 27 of the first embodiment, except that it does not have the fixed-side lock protrusion 33 and the guide groove 34 of the first embodiment. The attachment function part 65 has the same configuration as the clip 40 of the first embodiment, except that it does not have the connecting part 41 and the lock arm 43.

[0040] The assembly structure between the terminal holding member 17 and the multi-function member 63 is the same as the assembly structure between the terminal holding member 17 and the cover 27 in Example 1. The attachment structure between the attachment function portion 65 and the attachment target member 57 is the same as the attachment structure between the clip 40 (attachment portion 45) and the attachment target member 57 in Example 1. The wiring module 60 in Example 2 has a configuration in which the attachment function portion 65 (attachment portion) for attaching the wiring module 60 to the attachment target member 57 is formed integrally with the cover function portion 64 (cover) for protecting the board connecting portion 52 of the terminal fitting 50 from interference by foreign matter. With this configuration, the number of parts constituting the connector 61 can be reduced compared to when the attachment function portion 65 is a separate part from the cover function portion 64.

[0041] [Example 3] A third embodiment of the present disclosure will be described with reference to Figures 8 to 9. In this third embodiment, with regard to the front-to-rear direction, the F direction in Figures 8 and 9 is defined as the front. With regard to the up-down direction, the H direction in Figures 8 and 9 is defined as the up. With regard to the left-to-right direction, the R direction in Figure 9 is defined as the right. The left-to-right direction and the width direction are used synonymously. An attachment device C of a wiring module 70 in this third embodiment has an attachment structure between an attachment portion 74 and an attachment target member 75 that is different from that in the first and second embodiments. Since the other configurations are the same as those in the first and second embodiments, the same components are denoted by the same reference numerals, and descriptions of the structure, operation, and effect will be omitted.

[0042] A wiring module 70 of the present embodiment 3 includes the same flexible printed circuit board 11 as in the first embodiment, and a connector 71 mounted on the flexible printed circuit board 11. The connector 71 includes a housing 72 and a plurality of terminal fittings 50, which are the same components as in the first embodiment. The housing 72 is integrally provided with an attachment portion 74 that is attached directly to an attachment target member 75 to which the connector 71 is attached.

[0043] The housing 72 is configured by assembling a terminal holding member 17 having the same configuration as in the first embodiment and a cover 73. An attachment portion 74 for attaching the connector 71 to an attachment target member 75 is integrally formed on the upper surface (opposite surface 32) of the cover 73. The attachment portion 74 has the same structure as that of the cover 73 in the first embodiment for attaching a clip. That is, a fixed-side locking protrusion 33 and a pair of left and right guide grooves 34 are formed on the upper surface of the cover 73.

[0044] An attachment receiving portion 76 having the same structure as the attachment structure to the cover 73 of the clip of Example 1 is formed on the underside of the attachment target member 75. The attachment receiving portion 76 is the same portion of the clip 40 of Example 1 that has the same structure for attachment to the cover 73. That is, the attachment receiving portion 76 has a lock arm 43 having a movable lock protrusion 44 and a pair of left and right guide ribs 42. The assembly structure between the terminal holding member 17 and the cover 73 is the same as in Example 1. The attachment structure between the connector 71 and the attachment target member 75 is the same as the attachment structure between the cover 73 and the clip in Example 1.

[0045] [Example 4] A fourth embodiment of the present disclosure will be described with reference to Figures 10 to 11. In this fourth embodiment, with regard to the front-to-rear direction, the F direction in Figures 10 and 11 is defined as the front. With regard to the up-down direction, the H direction in Figures 10 and 11 is defined as the up. With regard to the left-to-right direction, the R direction in Figure 10 is defined as the right. The left-to-right direction and the width direction are used synonymously. In the mounting device D of the wiring module 80 of this fourth embodiment, the connector 81 has a different configuration from those of the first to third embodiments. Since the other configurations are the same as those of the first to third embodiments, the same reference numerals are used for the same configurations, and descriptions of the structure, operation, and effects will be omitted.

[0046] A wiring module 80 of this fourth embodiment includes the same flexible printed circuit board 11 as in the first embodiment, and a connector 81 mounted on the flexible printed circuit board 11. The connector 81 includes a housing 82 and a plurality of terminal fittings 50, which are the same components as in the first embodiment. The housing 82 is integrally provided with an attachment portion 83 that is attached directly to an attachment target member 57 to which the connector 81 is attached.

[0047] The housing 82 is a single component in which the terminal holding member 17 of Example 1 and the mounting portion 83 are integrated. The housing 82 has a plurality of terminal accommodating chambers 21 formed therein. The upper surface of the housing 82 is defined as the opposite surface 32 facing in the direction opposite to the opposing surface (lower surface).
