[0012] The protector 1 of this embodiment is a protective member for a flexible printed circuit board. The protector 1 constitutes, for example, a part of the bus bar module 100. The bus bar module 100 is assembled to the battery module 210 of the battery pack 200. The battery module 210 has a plurality of battery cells 220. The plurality of battery cells 220 are arranged along the arrangement direction BA.

[0013] The bus bar module 100 has a plurality of bus bars 110, a case 120, a flexible printed circuit board 3, a connector 10, and a protector 1. The bus bar 110 can be connected to the electrodes of the battery cells 220. The bus bar 110 connects, for example, the electrodes of two adjacent battery cells 220.

[0014] The case 120 houses the plurality of bus bars 110 and the flexible printed circuit board 3. The case 120 is molded, for example, from an insulating synthetic resin. The case 120 has a holding portion for holding the bus bars 110. The plurality of bus bars 110 are held side by side in the arrangement direction BA by the case 120. The case 120 is fixed to the battery module 210 while holding the plurality of bus bars 110 and the flexible printed circuit board 3.

[0015] The flexible printed circuit board 3 has a base film, a conductive layer, and a coverlay. The conductive layer is sandwiched and protected by the base film and the coverlay. The conductive layer is, for example, a conductive metal foil and has a circuit pattern including a plurality of detection lines. The detection lines are connected to the corresponding bus bars 110 and thermistors. The detection lines are connected to the monitoring unit 230 of the battery pack 200 via the connector 10.

[0016] The protector 1 is arranged, for example, at the end of the case 120 in the arrangement direction BA. The flexible printed circuit board 3 is routed from the case 120 to the connector 10 via the protector 1.

[0017] As shown in FIG. 2, the protector 1 has a case portion 2 and a slide body 4. The case portion 2 is formed of, for example, an insulating synthetic resin. The case portion 2 is connected to the end portion of the case 120 in the arrangement direction BA. The case portion 2 may be configured as a part of the case 120, may be engaged with the end portion of the case 120, or may be fixed to the battery module 210 or the like so as to be adjacent to the end portion of the case 120.

[0018] As will be described with reference to FIGS. 3 and 4, the protector 1 of the present embodiment can move the connector 10 in the slide direction X by sliding the slide body 4 with respect to the case portion 2. The protector 1 is configured to be able to move the connector 10 to a position where it can be fitted with the monitoring unit 230.

[0019] In this specification, in the slide direction X, the side where the connector 10 faces the mating connector 240 is referred to as the "first side X1". The mating connector 240 is a connector included in the monitoring unit 230 of the battery pack 200. The monitoring unit 230 is attached to the end portion of the battery module 210 in the arrangement direction BA. The monitoring unit 230 is disposed in the space between the housing of the battery pack 200 and the end face of the battery module 210.

[0020] In the slide direction X, the side opposite to the first side X1 is referred to as the "second side X2". The connector 10 can be detached from the mating connector 240 by moving to the second side X2.

[0021] The connector 10 shown in FIG. 3 is located at the end portion of the second side X2 in the slide direction X. That is, the connector 10 in FIG. 3 is at the position farthest from the mating connector 240 of the monitoring unit 230 within the movable range in the slide direction X. At this time, the slide body 4 is housed inside the case portion 2. The slide body 4 and the connector 10 can slide from the position shown in FIG. 3 toward the first side X1 toward the monitoring unit 230.

[0022] FIG. 4 shows a state where the mated connector 10 is mated with the mating connector 240. The slide body 4 protrudes from the case portion 2 toward the first side X1. The slide body 4 holds the flexible printed circuit board 3 and is fixed to the flexible printed circuit board 3. The connector 10 is connected to the end 3d of the flexible printed circuit board 3. Therefore, the slide body 4 can move in the slide direction X integrally with the connector 10.

[0023] In the protector 1 of the present embodiment, the connector 10 can be mated with the mating connector 240 in a state where both the protector 1 and the monitoring unit 230 are fixed to the battery module 210. Also, in the protector 1 of the present embodiment, the connector 10 can be removed from the mating connector 240 in a state where both the protector 1 and the monitoring unit 230 are fixed to the battery module 210. Therefore, the protector 1 of the present embodiment can improve the workability of the operation of attaching and detaching the connector 10 to and from the monitoring unit 230.

[0024] As shown in FIGS. 2 and 5, the case portion 2 has a passage portion 21, a housing chamber 22, and a guide portion 25. The passage portion 21, the housing chamber 22, and the guide portion 25 are integrally formed, for example. The passage portion 21 is disposed between the housing chamber 22 and the case 120 and is a portion that guides the flexible printed circuit board 3 to the housing chamber 22. The passage portion 21 is disposed adjacent to the end of the case 120. The passage portion 21 has a bottom wall 21a and a pair of side walls 21b. The passage portion 21 extends in the arrangement direction BA.

[0025] As shown in FIG. 9 and the like, the storage chamber 22 stores the redundant portion 31 of the flexible printed circuit board 3. The redundant portion of the flexible printed circuit board 3 is stored in the storage chamber 22 in a state of being folded back so as to form a substantially S shape. As shown in FIG. 5, the storage chamber 22 has a main body 23 and a cover 24. The main body 23 has a bottom wall 23a and a pair of side walls 23b. The bottom wall 23a and the pair of side walls 23b form a storage space 27 shown in FIG. 6. This storage space 27 stores the redundant portion 31 of the flexible printed circuit board 3. The cover 24 is connected to the side surface of the main body 23 via a hinge portion 24a.

[0026] In the description of the protector 1, the storage chamber 22 has a width direction Y and a depth direction Z of the storage space 27. The depth direction Z is a direction orthogonal to the bottom wall 23a, and is, for example, the same direction as the arrangement direction BA. The width direction Y is a direction in which the pair of side walls 23b face each other, and is the width direction of the flexible printed circuit board 3. The width direction Y and the depth direction Z are orthogonal.

[0027] As shown in FIG. 5, the guide portion 25 is provided on the side wall 23b and extends in the slide direction X. The slide direction X is orthogonal to the depth direction Z. That is, the slide direction X is orthogonal to the arrangement direction BA of the battery cells 220.

[0028] A support portion 26 for forming a first folding portion 32a on the flexible printed circuit board 3 is disposed on the main body 23. As shown in FIG. 6, the support portion 26 has a columnar or beam-shaped arm 26c. The flexible printed circuit board 3 is wound around the arm 26c of the support portion 26. The support portion 26 has a hinge portion 26a and an engaging portion 26b. The hinge portion 26a is disposed at one end of the arm 26c, and the engaging portion 26b is disposed at the other end of the arm 26c.

[0029] The arm 26c of the support portion 26 is connected to the side surface of the main body 23 via the hinge portion 26a and is rotatable with respect to the main body 23. The support portion 26 is engaged with the main body 23 by the engaging portion 26b. In a state where the engaging portion 26b is engaged with the main body 23, the arm 26c faces the bottom wall 23a of the main body 23. As shown in FIG. 6, a gap into which the flexible printed circuit board 3 can be inserted is provided between the arm 26c and the main body 23. That is, the support portion 26 constitutes a bridge straddling the flexible printed circuit board 3 placed on the bottom wall 23a.

[0030] As shown in FIG. 6, when the first folded portion 32a is formed by the support portion 26, an extra length portion 31 is generated on the flexible printed circuit board 3. The first folded portion 32a has a folded shape convex toward the first side X1. The accommodation space 27 of the accommodation chamber 22 has a depth capable of accommodating the extra length portion 31.

[0031] The slide body 4 is formed of, for example, an insulating synthetic resin. The slide body 4 slides with respect to the case portion 2 while being guided by the case portion 2. The slide body 4 holds the end portion 3d of the flexible printed circuit board 3 and is configured to slide together with the end portion 3d. The slide body 4 is movable to the first side X1 and the second side X2 within a movable range along the slide direction X.

[0032] As shown in FIG. 7, the slide body 4 has a main body 41 and a cover 42. The main body 41 and the cover 42 are integrally molded, for example. The main body 41 has a groove portion 41a capable of accommodating the flexible printed circuit board 3. The groove portion 41a extends in the slide direction X. The cover 42 has a hinge portion 42a and an engaging portion 42b. The hinge portion 42a is disposed at one end in the width direction of the cover 42, and the engaging portion 42b is disposed at the other end in the width direction of the cover 42. The hinge portion 42a is connected to the side surface of the main body 41. The cover 42 covers the groove portion 41a of the main body 41 and protects the flexible printed circuit board 3.

[0033] The main body 41 and the cover 42 function as a holding part for holding the flexible printed circuit board 3. The cover 42 is configured to sandwich and hold the flexible printed circuit board 3 between the main body 41 and the cover 42, for example.

[0034] At the end of the first side X1 of the main body 41, a widened portion 43 having a shape corresponding to the end 3d of the flexible printed circuit board 3 is formed. Two protrusions 43a are provided on the widened portion 43. The protrusions 43a are inserted into the through holes of the flexible printed circuit board 3 to hold the end 3d of the flexible printed circuit board 3.

[0035] As shown in FIG. 8, the slide body 4 has two legs 44. The legs 44 are arranged at both ends in the width direction Y of the main body 41. The legs 44 project from the main body 41 in the depth direction Z. At the tip of the legs 44, claws 44a projecting in the width direction Y are provided. The legs 44 are inserted into the guide portion 25 of the case portion 2. The side wall 23b of the case portion 2 suppresses the detachment of the legs 44 by locking the claws 44a.

[0036] The legs 44 are arranged at the end of the second side X2 of the main body 41. That is, the end of the second side X2 of the slide body 4 is connected to the case portion 2. On the other hand, the end of the first side X1 of the slide body 4 is not connected to the case portion 2 and is relatively movable with respect to the case portion 2. Therefore, the end of the first side X1 of the slide body 4 can be separated from the case portion 2. In other words, the slide body 4 can swing with respect to the case portion 2. When the slide body 4 can swing in the depth direction Z, the posture of the connector 10 changes flexibly when the connector 10 is inserted into and removed from the mating connector 240.

[0037] As shown in FIG. 9, the slide body 4 holds the flexible printed circuit board 3 so as to form a second folding portion 32b in the flexible printed circuit board 3. The slide body 4 is configured to hold a portion between the connector 10 and the extra length portion 31 in the flexible printed circuit board 3. The slide body 4 of the present embodiment holds the end portion 3d in the flexible printed circuit board 3 and holds the portion 3a adjacent to the end portion 3d. The adjacent portion 3a is a portion on the side opposite to the side of the connector 10 with respect to the end portion 3d. In other words, the adjacent portion 3a is a portion located on the second side X2 with respect to the end portion 3d. The slide body 4 sandwiches the adjacent portion 3a between the main body 41 and the cover 42.

[0038] The second folding portion 32b is formed so as to cover the main body 41 from both sides in the depth direction Z. The second folding portion 32b has a folding shape convex toward the second side X2. In the flexible printed circuit board 3, the portion on the end portion 3d side rather than the second folding portion 32b is the adjacent portion 3a. In the flexible printed circuit board 3, the portion on the side opposite to the end portion 3d rather than the second folding portion 32b is connected to the first folding portion 32a. The portion 3b between the first folding portion 32a and the second folding portion 32b faces the bottom wall 23a of the case portion 2 and is accommodated in the accommodation space 27. The accommodation space 27 is formed between the bottom wall 23a of the case portion 2 and the main body 41 of the slide body 4.

[0039] As described above, the slide body 4 forms the second folding portion 32b in the flexible printed circuit board 3 and folds the flexible printed circuit board 3 into a substantially U shape. The flexible printed circuit board 3 is held by the protector 1 so as to form a substantially S shape having two folding portions 32a and 32b.

[0040] The main body 41 of the slide body 4 has a protection part 45. The protection part 45 is provided at the end of the main body 41 on the second side X2. The protection part 45 protects the flexible printed circuit board 3 so that the bending R in the second folding part 32b does not become excessively small. The protection part 45 has a substantially cylindrical shape. The protection part 45 bulges toward one side in the depth direction Z. The direction in which the protection part 45 bulges is the side toward the bottom wall 23a of the case part 2. Therefore, the second folding part 32b curves so as to bulge toward the bottom wall 23a. Thereby, an increase in the size of the slide body 4 in the depth direction Z is suppressed.

[0041] The support part 26 of the case part 2 is formed so that the bending R in the first folding part 32a does not become excessively small. That is, the arm 26c of the support part 26 bulges toward the main body 41 of the slide body 4 along the depth direction Z.

[0042] In the case part 2, a thin part 21c is provided between the bottom wall 21a and the bottom wall 23a. The thin part 21c is arranged at the corner where the two bottom walls 21a and 23a intersect and is curved in an arc shape. The plate thickness of the thin part 21c is thinner than that of the two bottom walls 21a and 23a. Therefore, the thin part 21c allows the bottom wall 23a to swing with respect to the bottom wall 21a.

[0043] In the protector 1 of the present embodiment, the accommodation chamber 22 can swing in the depth direction Z with the thin part 21c as the rotation center. Further, as described above, the slide body 4 can swing with respect to the accommodation chamber 22. Therefore, the protector 1 of the present embodiment enables both the position adjustment of the connector 10 in the depth direction Z and the angle adjustment of the connector 10 with respect to the slide direction X.

[0044] The end portion 3d of the flexible printed circuit board 3 protrudes from the slide body 4 and is connected to the connector 10. The slide body 4 holds the end portion 3d of the flexible printed circuit board 3 by the protrusion 43a. The illustrated protrusion 43a has a cylindrical shape. A reinforcing plate 5 for reinforcing the flexible printed circuit board 3 is attached to the end portion 3d. Through holes corresponding to the protrusion 43a are provided in the end portion 3d and the reinforcing plate 5. The protrusion 43a is inserted into the through holes of the end portion 3d and the reinforcing plate 5 to hold the end portion 3d and the reinforcing plate 5.

[0045] The slide body 4 in FIG. 9 is located at the end of the second side X2 within the slidable range. At this time, the protective portion 45 of the slide body 4 is located inside the second folded portion 32b and supports the folded portion 32b.

[0046] When the slide body 4 and the connector 10 move to the first side X1 from this state, the surplus portion 31 of the flexible printed circuit board 3 extends from the accommodation chamber 22. The surplus portion 31 extends from the space between the main body 41 of the slide body 4 and the bottom wall 23a of the case portion 2 to the external space. More specifically, when the slide body 4 moves to the first side X1, the position where the second folded portion 32b is formed approaches the first folded portion 32a. As a result, the portion 3b between the first folded portion 32a and the second folded portion 32b is pulled out to the external space.

[0047] The slide body 4 in FIG. 10 is located at the end of the first side X1 within the slidable range. At this time, the protective portion 45 of the slide body 4 is separated from the second folded portion 32b. Most of the slide body 4 protrudes from the accommodation chamber 22 to the first side X1. When the slide body 4 protrudes to the end of the first side X1 within the movable range, the flexible printed circuit board 3 has two folded portions 32a and 32b. That is, the flexible printed circuit board 3 maintains a substantially S-shaped curved shape regardless of the position of the slide body 4 within the movable range. Thereby, the shape of the flexible printed circuit board 3 is less likely to be disturbed.

[0048] In the protector 1 of the present embodiment, the movable range St of the slide body 4 is set so that the connector 10 can be inserted into and removed from the mating connector 240. That is, by moving the slide body 4 to the second side X2, the connector 10 can be detached from the mating connector 240. Further, by moving the slide body 4 to the first side X1, the connector 10 can be fully fitted to the mating connector 240.

[0049] Thus, the protector 1 of the present embodiment is configured such that the connector 10 can be inserted into and removed from the mating connector 240 with both the mating connector 240 and the case portion 2 fixed. Therefore, the protector 1 of the present embodiment can improve the workability of the attachment and detachment operation of the connector 10 with respect to the mating connector 240.

[0050] As described above, the protector 1 of the present embodiment includes a case portion 2 and a slide body 4. The case portion 2 includes a housing chamber 22 and a guide portion 25. The housing chamber 22 houses the excess portion 31 of the flexible printed circuit board 3 to which the connector 10 is connected. The guide portion 25 extends along the slide direction X. The slide body 4 has a holding portion. The holding portion holds the portion between the connector 10 and the excess portion 31 on the flexible printed circuit board 3. The slide body 4 of the present embodiment has a sandwiching structure by the main body 41 and the cover 42 and a protrusion 43a as the holding portion. The main body 41 and the cover 42 hold the portion 3a adjacent to the end portion 3d on the flexible printed circuit board 3. The protrusion 43a holds the end portion 3d of the flexible printed circuit board 3.

[0051] The case portion 2 and the slide body 4 are configured to be capable of an extending operation and a housing operation. The extending operation is an operation of extending the excess portion 31 from the housing chamber 22. The case portion 2 and the slide body 4 are configured such that the excess portion 31 is extended from the housing chamber 22 when the slide body 4 moves to the first side X1 in the slide direction X.

[0052] The housing operation is an operation of housing the excess portion 31 in the housing chamber 22. The case portion 2 and the slide body 4 house the excess portion 31 extending from the housing chamber 22 into the housing chamber 22 by moving the slide body 4 toward the second side X2 in the slide direction X. The protector 1 of the present embodiment can improve the workability of the operation of attaching and detaching the connector 10 to and from the mating connector 240 by moving the connector 10 in the slide direction X.

[0053] In the case portion 2 and the slide body 4 of the present embodiment, a plurality of folding portions 32a and 32b are formed in the excess portion 31, and the excess portion 31 is configured to be laminated in the housing chamber 22. In the illustrated protector 1, two folding portions 32a and 32b are formed in the flexible printed circuit board 3, and the excess portion 31 is laminated in the housing space 27. In the flexible printed circuit board 3, the laminated portions may be spaced apart from each other or may be in contact with each other. By laminating and housing the excess portion 31, the low-profile of the case portion 2 is realized.

[0054] The case portion 2 of the present embodiment has a support portion 26. The support portion 26 forms a first folding portion 32a in the excess portion 31 and supports the first folding portion 32a from the inside. The first folding portion 32a has a folding shape convex toward the first side X1. The support portion 26 can support the first folding portion 32a and stabilize the shape of the excess portion 31.

[0055] The slide body 4 of the present embodiment holds the flexible printed circuit board 3 by a holding portion so as to form a second folding portion 32b in the excess portion 31. For example, the sandwiching structure by the main body 41 and the cover 42 sandwiches the adjacent portion 3a so as to form the second folding portion 32b. The holding portion of the slide body 4 can stabilize the shape of the excess portion 31.

[0056] The bus bar module 100 of the present embodiment includes a protector 1, a flexible printed circuit board 3, a connector 10 connected to the flexible printed circuit board 3, and a plurality of bus bars 110. The plurality of bus bars 110 are connected to the flexible printed circuit board 3 and can be connected to the electrodes of the battery cell 220. The bus bar module 100 of the present embodiment can improve the workability of the operation of attaching and detaching the connector 10 to and from the mating connector 240.

[0057] Note that the object to which the protector 1 of the present embodiment is applied is not limited to the bus bar module 100. The mating connector 240 is not limited to the connector of the monitoring unit 230.

[0058] The protector 1 may be applied to, for example, the flexible printed circuit board 3 routed along the vehicle body of the vehicle. In this case, the flexible printed circuit board 3 may connect an ECU (electronic control unit) and a device controlled by the ECU. The mating connector 240 may be the connector of the ECU or the connector of the device to be controlled. The protector 1 of the present embodiment can fit the connector 10 to the mating connector 240 or detach the connector 10 from the mating connector 240 in a state where both the mating connector 240 and the protector 1 are fixed.

[0059] The slide body 4 may have a holding portion for holding the connector 10. In this case, when a force in the slide direction X is applied to the slide body 4 or the connector 10, the force is less likely to act on the flexible printed circuit board 3.

[0060] The number of the folded-back portions formed in the redundant portion 31 is not limited to the two illustrated ones. The protector 1 may form three or more folded-back portions in the redundant portion 31. The shape of the redundant portion 31 accommodated in the accommodation chamber 22 is not limited to the S shape. For example, the redundant portion 31 may be accommodated in the accommodation chamber 22 in any shape. When the shape of the redundant portion 31 in the accommodation chamber 22 is not controlled, the case portion 2 may not have the support portion 26, and the slide body 4 may not have the protection portion 45.

[0061] [Modification of Embodiment] Referring to FIGS. 11 and 12, the protector 1 according to a modification of the embodiment will be described. FIGS. 11 and 12 are plan views of the protector according to a modification of the embodiment. In the protector 1 according to a modification of the embodiment, the difference from the protector 1 of the above embodiment is, for example, that the flexible printed circuit board 3 extends in the width direction Y.

[0062] As shown in FIG. 12, in the protector 1 according to a modification of the embodiment, the flexible printed circuit board 3 and the connector 10 extend from the slide body 4 in the width direction Y. Thereby, even if the position of the mating connector 240 in the slide direction X is different, the connector 10 can be positioned at an appropriate position with respect to the mating connector 240.

[0063] As shown in FIG. 11, the main body 41 of the slide body 4 has a protruding portion 46. The protruding portion 46 protrudes toward the first side X1 with respect to the cover 42. The protruding portion 46 has a groove portion 41a capable of accommodating the flexible printed circuit board 3. A drawer opening 46a is provided in the protruding portion 46. The drawer opening 46a opens in the width direction Y.

[0064] As shown in FIG. 12, a flexible printed circuit board 3 is formed with a bent portion 3c. The bent portion 3c is bent so as to change the extending direction of the flexible printed circuit board 3 by 90°. The tip side of the flexible printed circuit board 3 beyond the bent portion 3c protrudes along the width direction Y from the lead-out port 46a. The flexible printed circuit board 3 is provided with a surplus length corresponding to the stroke for insertion and removal with respect to the mating connector 240. That is, in the flexible printed circuit board 3, the portion protruding from the lead-out port 46a has a surplus length that enables the connector 10 to be fitted to the mating connector 240.

[0065] The slide body 4 can position the connector 10 at an arbitrary position within the movable range by moving along the slide direction X. Therefore, the protector 1 according to the modification of the embodiment can improve the workability of the attachment / detachment operation of the connector 10 with respect to the mating connector 240.

[0066] The contents disclosed in the above embodiments and modifications can be executed in appropriate combination.
