[0009] [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. The wiring module of the present disclosure includes: (1) A connector includes a flexible printed circuit board and a connector mounted on the flexible printed circuit board. The connector includes a housing, a plurality of terminal fittings held in the housing, and a cover that covers board connection portions of the terminal fittings that are connected to the flexible printed circuit board by soldering. According to the configuration of the present disclosure, the cover prevents foreign matter from adhering to the board connection portions, thereby preventing short circuits between the board connection portions due to the adhesion of foreign matter.

[0010] (2) In (1), the cover preferably has a partition wall that separates the adjacent board connection parts. This configuration can reliably prevent short circuits between the adjacent board connection parts.

[0011] (3) In (1) or (2), it is preferable that the board connection portion has a mounting portion that extends cantilevered rearward of the housing and is surface-mounted on the flexible printed circuit board, and that the rear wall of the cover has a notch that accommodates the mounting portion. With this configuration, the front-to-rear length of the connector can be shortened compared to when the rear wall is located rearward of the rear end of the mounting portion.

[0012] (4) In (3), it is preferable that the plurality of board connection parts are arranged in a width direction perpendicular to the front-rear direction, and the plurality of cutouts are formed to individually accommodate the plurality of mounting parts. With this configuration, the total opening area of ​​the cutouts can be reduced compared to when the plurality of board connection parts are accommodated in a single cutout space that is connected in the width direction, and therefore, the effect of preventing foreign matter from entering the inner peripheral surface of the cover through the cutouts is high.

[0013] (5) In (1) or (2), it is preferable that pegs for fixing the housing to the flexible printed circuit board are arranged on the outer surface of the housing, and side walls constituting the cover are arranged in areas of the outer surface of the housing where the pegs are not arranged. With this configuration, the width of the connector can be made smaller than when the pegs and the side walls are arranged overlapping each other in the width direction perpendicular to the outer surface.

[0014] (6) In (1) or (2), it is preferable that the outer surface of the housing includes an opposing surface facing the flexible printed circuit board, the cover has an attachment portion on an opposite surface facing the opposing surface to be attached to a target member, and the housing and the cover have mating portions that are mated in a direction perpendicular to the opposing surface and the opposite surface. With this configuration, there is no risk of the cover and the housing coming apart when an external force acts on the housing in a direction intersecting the opposing surface and the opposite surface.

[0015] [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.

[0016] The wiring module A of the first embodiment includes a flexible printed circuit board 10 (FPC), which is a type of circuit board, and a connector 20 mounted on a mounting surface 11 of the flexible printed circuit board 10. The structure of the wiring module A will be described below in a state where the flexible printed circuit board 10 is horizontally arranged with the mounting surface 11 facing upward. A reinforcing plate 12 is fixed to the underside of the flexible printed circuit board 10 in an area where the connector 20 is mounted, in order to increase the rigidity of the flexible printed circuit board 10 and suppress bending deformation.

[0017] The connector 20 has a housing 21 that is a single component made of synthetic resin, a plurality of terminal fittings 30, a cover 40 that is a single component made of synthetic resin, and a clip 60 that is a single component. The lower surface of the housing 21 is defined as an opposing surface 22 that faces the mounting surface 11 of the flexible printed circuit board 10. Metal pegs 23 with their thickness oriented in the left-right direction are fixed to the lower end regions of both the left and right outer surfaces of the housing 21. The pair of left and right pegs 23 are fixed to the mounting surface 11 of the flexible printed circuit board 10 by soldering.

[0018] A plurality of terminal accommodating chambers 24 are formed inside the housing 21, penetrating the housing 21 in the front-to-rear direction. Protrusions 25 are formed at the front end portions of both left and right outer surfaces of the housing 21. Fitting holes 26 are formed in the protrusions 25, penetrating the protrusions 25 in the front-to-rear direction. A pair of left and right protective wall portions 27 are formed at the rear end portion of the housing 21, protruding rearward from both left and right edge portions. A retaining protrusion 28 is formed at the rear end portion of the outer wall surface of the protective wall portion 27. A fitting groove 29 is formed in the front-to-rear direction on the inner wall surface at the rear end portion of the protective wall portion 27.

[0019] The terminal fitting 30 is a single component having a terminal body 31 and a board connecting portion 32. The terminal body 31 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 31. When a mating connector (not shown) is mated with the connector 20, a tab of a male terminal (not shown) provided on the mating connector is inserted into the terminal body 31, and the resilient contact piece resiliently contacts the tab. The terminal body 31 is housed within the terminal accommodating chamber 24.

[0020] The board connection portion 32 is a long, narrow portion that extends cantilevered rearward from the rear end of the terminal body 31. The board connection portion 32 has a horizontal portion 33 that extends rearward from the rear end of the underside of the terminal body 31, leg portions 34 that extend downward from the rear end of the horizontal portion 33, and a mounting portion 35 that extends rearward from the lower end of the leg portion 34. Most of the area of ​​the board connection portion 32, excluding the front end portion of the horizontal portion 33, protrudes rearward from the housing 21 and is positioned so as to be sandwiched between a pair of protective walls 27.

[0021] The cover 40 has an upper wall portion 41, a pair of outer wall portions 42 protruding downward from both left and right edges of the upper wall portion 41, a pair of inner wall portions 43 protruding downward from the rear end of the upper wall portion 41, and a rear wall portion 44 protruding downward from the rear end edge of the upper wall portion 41. The rear end edge of the outer wall portion 42 and the side edge of the rear wall portion 44 are joined at a right angle to each other. The rear end edge of the inner wall portion 43 and the side edge of the rear wall portion 44 are joined at a right angle to each other. The upper surface of the upper wall portion 41 is defined as an opposing surface 45 that faces in the vertically opposite direction from the opposing surface 22. The opposing surface 45 is formed with a fixed-side locking protrusion 46 and a pair of left and right guide grooves 47. A forward-protruding mating protrusion 48 is formed at the front end of each of the left and right outer wall portions 42. A front-rear-extending mating rib 49 is formed at the rear end of each of the left and right inner wall portions 43.

[0022] A plurality of notches 50 are formed in the lower end of the rear wall 44. The plurality of notches 50 are arranged side by side at intervals in the left-right direction. Each notch 50 is open on both the front and rear surfaces and the bottom surface of the rear wall 44. Each notch 50 is adapted to accommodate the rear end of a mounting portion 35 of a terminal fitting 30, which will be described later. A plurality of partition walls 51 are formed inside the cover 40, with their wall thickness direction oriented in the left-right direction. The partition walls 51 are connected to the bottom surface of the upper wall 41 and the front surface of the rear wall 44, and are arranged in parallel at intervals in the left-right direction.

[0023] The cover 40 is attached to the housing 21. The upper wall portion 41 of the cover 40 is arranged to cover the upper surface of the housing 21 from above. The outer wall portion 42 and the inner wall portion 43 are arranged to cover the outer side surfaces of the housing 21. The rear wall portion 44 is arranged to cover the rear surface of the housing 21 from behind.

[0024] When the cover 40 is attached to the housing 21, the fitting protrusions 48 fit into the fitting holes 26 from the rear, thereby restricting the vertical and horizontal displacement of the cover 40 relative to the housing 21. The fitting ribs 49 fit into the fitting grooves 29 from the rear, thereby restricting the vertical displacement of the cover 40 relative to the housing 21. The locking portions (not shown) of the cover 40 engage with the anti-slip protrusions 28, thereby restricting the rearward displacement of the cover 40 relative to the housing 21.

[0025] The board connection portions 32 of the terminal fittings 30 are exposed to the rear outside of the housing 21 and are simultaneously housed inside the cover 40. Adjacent board connection portions 32 in the left-right direction are separated by partition walls 51 of the cover 40. The rear end portions of the mounting portions 35 are housed in the plurality of cutout portions 50 one by one.

[0026] The clip 60 is made of a synthetic resin material. The clip 60 is a single member that integrates a connecting portion 61 and an attachment portion 65. A pair of guide ribs 62 extending in the front-rear direction are formed on both left and right edges of the connecting portion 61. A lock arm 63 that is elastically deformable in the vertical direction is formed on the underside of the connecting portion 61. A movable-side lock protrusion 64 is formed on the underside of the lock arm 63. The attachment portion 65 has a base 66, a flange 67, and a pair of symmetrical elastic retaining pieces 68. The base 66 protrudes upward from the top surface of the connecting portion 61. The flange 67 protrudes radially outward from the outer periphery of the lower end of the base 66. In a plan view of the clip 60 from above, the flange 67 is circular. The pair of elastic retaining pieces 68 extend diagonally downward in a cantilevered manner from the upper end of the base 66. The pair of elastic retaining pieces 68 are capable of elastic deformation in the radial direction (left and right direction).

[0027] The clip 60 is assembled by sliding it from rear to front relative to the opposing surface 45 of the cover 40. During assembly, the pair of guide ribs 62 are fitted into the pair of guide grooves 47. During the assembly process, the movable-side locking protrusion 64 of the locking arm 63 interferes with the fixed-side locking protrusion 46 of the cover 40, causing the locking arm 63 to elastically deform upward. When the clip 60 is attached to the cover 40, the movable-side locking protrusion 64 engages with the fixed-side locking protrusion 46, thereby holding the clip 60 in a state where it is prevented from being removed from the cover 40. When the clip 60 is assembled to the cover 40, the mounting portion 65 of the clip 60 is disposed on the opposing surface 45 (top surface) of the housing 21.

[0028] The connector 20 is configured by attaching the terminal fittings 30 and the cover 40 to the housing 21 and then attaching the clip 60 to the cover 40. The connector 20 is mounted on the flexible printed circuit board 10 by soldering. Specifically, the housing 21 is fixed to the flexible printed circuit board 10 by soldering the pegs 23 to the mounting surface 11. The mounting portion 35 of each terminal fitting 30 is soldered to be conductively attached to the flexible printed circuit board 10. The flexible printed circuit board 10 does not have a through-hole, and the mounting portion 35 is surface-mounted to the mounting surface 11. The lower edge of the rear wall portion 44 of the cover 40 is located close to the mounting surface 11 of the flexible printed circuit board 10 so as to face it in a non-contact state. The outer wall portion 42 and the inner wall portion 43 also remain in a non-contact state with the flexible printed circuit board 10. The wiring module A is configured by mounting the connector 20 on the flexible printed circuit board 10.

[0029] The wiring module A is attached to an attachment target member 70 by an attachment portion 65 of a clip 60. The attachment target member 70 is a horizontal plate-shaped member. Specifically, the attachment target member 70 is a support member for supporting a bus bar in a battery pack of a secondary battery (not shown), the body of an automobile, or the like. The attachment target member 70 has a circular attachment hole 71 formed therein, which penetrates the attachment target member 70 in the vertical direction (plate thickness direction).

[0030] When attaching the clip 60 to the attachment target component 70, the attachment portions 65 of the clip 60 are fitted into the attachment holes 71 from below the attachment target component 70. During the fitting process, the pair of elastic retaining pieces 68 are elastically deformed by interfering with the opening edges of the attachment hole 71. The flange portions 67 abut against the underside of the attachment target component 70 and elastically deform, and when the elastic retaining pieces 68 pass through the attachment hole 71, the elastic retaining pieces 68 elastically return radially outward and engage with the opening edges of the attachment hole 71 on the upper surface of the attachment target component 70. The attachment target component 70 is sandwiched between the flange portions 67 and the elastic restoring force, and the wiring module A is attached to the attachment target component 70.

[0031] When the wiring module A is attached to the attachment target member 70, the flexible printed circuit board 10 does not come into contact with the attachment target member 70. Only the clip 60 of the wiring module A directly abuts against the attachment target member 70. Therefore, the mating resistance acting on the connector 20 during the mating process between the connector 20 and the mating connector acts on the attachment target member 70 via the attachment portion 65 of the clip 60, but does not act on the soldered portion between the flexible printed circuit board 10 and the mounting portion 35 of the terminal fitting 30.

[0032] The wiring module A of the first embodiment includes a flexible printed circuit board 10 and a connector 20 mounted on the flexible printed circuit board 10. The connector 20 includes a housing 21, a plurality of terminal fittings 30 held by the housing 21, and a cover 40. The cover 40 covers the board connection portions 32 of the terminal fittings 30 that are connected to the flexible printed circuit board 10 by soldering. With this configuration, the cover 40 prevents foreign matter from adhering to the board connection portions 32, thereby preventing short circuits between the board connection portions 32 due to the attachment of foreign matter. The cover 40 has a partition portion 51 that separates adjacent board connection portions 32, thereby reliably preventing short circuits between adjacent board connection portions 32.

[0033] The board connection portion 32 has a mounting portion 35 that extends cantilevered rearward from the housing 21 and is surface-mounted on the flexible printed circuit board 10. A cutout 50 that accommodates the mounting portion 35 is formed in the rear wall portion 44 of the cover 40. With this configuration, the front-to-rear length of the connector 20 can be shortened compared to when the rear wall portion 44 is positioned rearward of the rear end of the mounting portion 35.

[0034] The multiple board connection portions 32 are arranged side by side in the width direction perpendicular to the front-rear direction. The multiple cutout portions 50 are formed to individually accommodate the multiple mounting portions 35. With this configuration, the total opening area of ​​the cutout portions 50 can be reduced compared to when multiple board connection portions 32 are accommodated in a single cutout space that is connected in the width direction, which makes it more effective at preventing foreign matter from entering the cover 40 through the cutout portions 50.

[0035] Pegs 23 for fixing the housing 21 to the flexible printed circuit board 10 are arranged in a lower end region of the outer surface of the housing 21. The outer wall portion 42 of the cover 40 is arranged in an upper end region of the outer surface of the housing 21 where the pegs 23 are not arranged. With this configuration, the dimension of the connector 20 in the width direction can be made smaller than when the pegs 23 and the outer wall portion 42 are arranged overlapping in the width direction perpendicular to the outer surface.

[0036] The outer surface of the housing 21 includes an opposing surface 22 (bottom surface) that faces the flexible printed circuit board 10. An opposing surface 45 of the cover 40, which faces the opposite side to the opposing surface 22, is provided with an attachment portion 65 that is attached to an attachment target member 70. The housing 21 and the cover 40 are formed with fitting holes 26 and fitting protrusions 48 as fitting portions that fit together in the front-to-rear direction perpendicular to the opposing surface 22 and the opposing surface 45. With this configuration, there is no risk of the cover 40 and the housing 21 coming apart when an external force acts on the housing 21 in the vertical direction that intersects with the opposing surface 22 and the opposing surface 45.

[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. The wiring module B of this second embodiment has a connector 80 with a different structure from 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 effects will be omitted.

[0038] The wiring module B includes the same flexible printed circuit board 10 as in the first embodiment, and a connector 80 mounted on the flexible printed circuit board 10. The connector 80 includes a housing 21, which is the same component as in the first embodiment, a plurality of terminal fittings 30, which are the same components as in the first embodiment, and a multi-function member 81.

The cover function part 82 has the same configuration as the cover 40 of Example 1, except that it does not have the fixed-side locking protrusion 46 and the guide groove 47 of Example 1. The attachment function part 83 has the same configuration as the clip 60 (attachment part 65) of Example 1, except that it does not have the connecting part 61 and the locking arm 63.

The attachment structure between the attachment function portion 83 and the attachment target member 70 is the same as the attachment structure between the clip 60 (attachment portion 65) and the attachment target member 70 in Example 1. The wiring module B in Example 2 has a configuration in which the attachment function portion 83 (attachment portion) for attaching the wiring module B to the attachment target member 70 is integrally formed with the cover function portion 82 (cover) for protecting the board connecting portion 32 of the terminal fitting 30 from interference by foreign matter. With this configuration, the number of parts constituting the connector 80 can be reduced compared to when the attachment function portion 83 is a separate part from the cover function portion 82.

[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. The wiring module C of this third embodiment has a mounting structure to a mounting target member 95 that is different from that of the first and second embodiments. Since the other configurations are the same as those of the first and second embodiments, the same configurations are denoted by the same reference numerals, and descriptions of the structure, action, and effect will be omitted.

[0042] The wiring module C of the third embodiment includes the same flexible printed circuit board 10 as in the first embodiment, and a connector 90 mounted on the flexible printed circuit board 10. The connector 90 includes a housing 21 having the same configuration as in the first embodiment, a plurality of terminal fittings 30 which are the same components as in the first embodiment, and a cover 40 having the same configuration as in the first embodiment. An attachment portion 91 for attaching the connector 90 to an attachment target member 95 is integrally formed on the upper surface (opposite surface 45) of the cover 40. The attachment portion 91 has the same structure as that for attaching the clip 60 of the cover 40 of the first embodiment. That is, a fixed-side locking protrusion 46 and a pair of left and right guide grooves 47 are formed on the upper surface of the cover 40.

[0043] An attachment receiving portion 96 having the same structure as the attachment structure to the cover of the clip of Example 1 is formed on the underside of the attachment target member 95. That is, the attachment receiving portion 96 has the same structure as that of the clip 60 of Example 1 for attachment to the cover 40. That is, a lock arm 63 having a movable-side locking protrusion 64 and a pair of left and right guide ribs 62 are formed on the underside of the attachment target member 95. The assembly structure between the housing 21 and the cover 40 is the same as that of Example 1.
