Problems to be Solved by the Invention

[0004] However, in the technique disclosed in Patent Document 1, since the lid portion is attached to the case body via a hinge portion, the hinge portion may protrude from the case body, and the lid portion may interfere with adjacent components.

[0005] The present invention has been made in view of such problems of the prior art. An object of the present invention is to provide a bus bar wiring module capable of more reliably suppressing the interference between an opening / closing cover rotatably attached to a protective cover and adjacent components. [Means for solving the problem]

[0006] A busbar routing module according to an aspect of the present invention comprises a protective cover, a busbar routed to the protective cover, a busbar exposure space formed in the protective cover in which a part of the busbar is exposed, an opening / closing cover covering the opening of the busbar exposure space, a first holding part that releasably holds one end of the opening / closing cover to the protective cover, and a second holding part that releasably holds the other end of the opening / closing cover to the protective cover. The opening / closing cover is configured such that, by moving it parallel to the protective cover in the direction normal to the opening of the busbar exposure space, one end is held by the protective cover by the first holding part and the other end is held by the protective cover by the second holding part. With one end held by the first holding part to the protective cover, the holding of the other end by the second holding part to the protective cover can be released, allowing the opening / closing cover to rotate relative to the protective cover with the first holding part as an axis. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a busbar routing module that can more reliably prevent interference between an opening / closing cover, which is rotatably attached to a protective cover, and adjacent components. [Brief explanation of the drawing]

[0009] The busbar routing module according to this embodiment will be described in detail below with reference to the drawings. Note that the dimensional ratios in the drawings are exaggerated for illustrative purposes and may differ from the actual ratios.

[0010] The busbar routing module 1 according to this embodiment is installed in a vehicle such as an automobile and is formed by holding busbars 3, which are routed between stacks of high-voltage batteries for driving the automobile, with a protective cover 2. In this embodiment, the busbar routing module 1 shown in Figures 1 and 2 and the busbar routing module 1 shown in Figures 3 and 4 are given as examples of such a busbar routing module 1.

[0011] The busbar 3 is a conductive conductor and can be manufactured, for example, by performing various processes such as punching or bending using a die on a conductive plate material. The shape of the busbar 3 is not particularly limited, but for example, as shown in Figure 2, it may have a complex shape extending in three directions in orthogonal coordinates, or as shown in Figure 4, it may have a shape extending in two directions in orthogonal coordinates. The material of the busbar 3 is also not particularly limited, but for example, it may be a metallic material such as copper or aluminum.

[0012] As described above, the busbar routing module 1 is equipped with a protective cover 2, which is fixed to a panel (not shown) such as a body panel inside the vehicle.

[0013] In this embodiment, the protective cover 2 comprises an upper cover (first cover) 21 and a lower cover (second cover) 22. The busbar 3 is housed in the internal space formed when the upper cover (first cover) 21 and the lower cover (second cover) 22 are combined, thereby protecting the busbar 3 from the protective cover 2. The upper cover (first cover) 21 and the lower cover (second cover) 22 can be formed, for example, by injection molding using a synthetic resin material.

[0014] The upper cover (first cover) 21 is formed in an inverted U-shape in cross-section, having a top wall portion 211 and a pair of upper side wall portions 212, 212. Furthermore, each of the pair of upper side wall portions 212, 212 has a locking frame (locking portion) 2121 into which a hook portion (locking portion) 2221 is locked.

[0015] On the other hand, the lower cover (second cover) 22 is a component covered by the upper cover (first cover) 21. This lower cover (second cover) 22 is formed in a U-shape in cross-section, having a bottom wall portion 221 and a pair of lower side wall portions 222, 222. Each of the pair of lower side wall portions 222, 222 has a hook portion (receiving portion) 2221 that is locked to a locking frame (locking portion) 2121.

[0016] Furthermore, a bus bar exposure space 23 is formed in the protective cover 2, and the bus bar 3 is held by the protective cover 2 in a state where a part thereof is exposed from the opening 23a of the bus bar exposure space 23. In the present embodiment, by protruding a part of the upper cover (first cover) 21 from the lower cover (second cover) 22, the bus bar exposure space 23 defined by the upper cover (first cover) 21 is formed. Then, the bus bar 3 is held by the protective cover 2 in a state where the end portion 3a of the bus bar 3 is positioned within the bus bar exposure space 23. By doing so, the end portion 3a of the bus bar 3 is exposed from the opening 23a of the bus bar exposure space 23. The end portion 3a of this bus bar 3 functions as a connection terminal portion to which a terminal portion or the like of another member (not shown) is electrically connected.

[0017] In the present embodiment, a pair of bus bars 3 are held by the protective cover 2, and the end portions 3a of each bus bar 3 are juxtaposed within the bus bar exposure space 23. Therefore, in the present embodiment, a partition wall 231 is provided in the bus bar exposure space 23 so as to secure an insulation distance between the end portions 3a of the bus bars 3 juxtaposed with each other.

[0018] Furthermore, in the present embodiment, as shown in FIGS. 5 and 6, an opening / closing cover 4 is rotatably attached to the protective cover 2. By rotating the opening / closing cover 4 with respect to the protective cover 2, the opening 23a of the bus bar exposure space 23 is covered by the opening / closing cover 4 so as to be openable and closable. By doing so, when the opening 23a of the bus bar exposure space 23 is covered by the opening / closing cover 4, the end portion 3a of the bus bar 3 exposed in the bus bar exposure space 23 is protected by the opening / closing cover 4. Further, when the opening / closing cover 4 is rotated to open the opening 23a of the bus bar exposure space 23, connection work of a terminal portion or the like of another member to the end portion 3a of the bus bar 3, inspection of the connection state of a terminal portion or the like of another member to the end portion 3a of the bus bar 3, and the like can be performed.

[0019] Note that adjacent components 7 as shown in FIG. 9 are arranged around the bus bar wiring module 1. In order to save space, it is preferable to place the adjacent components 7 as close as possible to the bus bar wiring module 1. However, it is necessary to ensure that the opening / closing cover 4 rotatably attached to the protective cover 2 does not interfere with the adjacent components 7 close to the bus bar wiring module 1.

[0020] Therefore, when arranging the adjacent components 7 in the vicinity of the opening / closing cover 4 rotatably attached to the protective cover 2, it is preferable to place the adjacent components 7 as close as possible to the opening / closing cover 4 while suppressing interference between the opening / closing cover 4 and the adjacent components 7.

[0021] Therefore, in the present embodiment, the opening / closing cover 4 is rotatably attached to the protective cover 2 without providing a hinge portion. By doing so, it is possible to suppress interference between the opening / closing cover 4 and the adjacent components 7 while bringing the adjacent components 7 as close as possible to the opening / closing cover 4.

[0022] Specifically, the bus bar wiring module 1 includes a first holding portion 5 that releasably holds one end side of the opening / closing cover 4 to the protective cover 2, and a second holding portion 6 that releasably holds the other end side of the opening / closing cover 4 to the protective cover 2.

[0023] And by translating the protective cover 2 in a direction parallel to the normal direction of the opening 23a of the bus bar exposure space 23, the opening / closing cover 4 is configured such that one end side is held by the protective cover 2 by the first holding portion 5 and the other end side is held by the protective cover 2 by the second holding portion 6.

[0024] Furthermore, with one end side held by the protective cover 2 by the first holding portion 5, the holding of the other end side to the protective cover 2 by the second holding portion 6 is released, and the opening / closing cover 可以4 is configured to be rotatable with respect to the protective cover 2 about the first holding portion 5 as an axis.

[0025] In this embodiment, the opening / closing cover 4 comprises a top wall 41 and a peripheral wall 42, and a pair of locking portions 43 are formed so as to protrude downward from the lower surface of one end of the top wall 41. In this embodiment, each locking portion 43 comprises a locking piece 431 and a locking projection 432 formed at the tip of the locking piece 431.

[0026] Then, by moving the opening / closing cover 4 parallel to the protective cover 2 in the direction normal to the opening 23a of the busbar exposure space 23, the locking projections 432 formed at the tips of the pair of locking parts 43 are held by the pivot shaft 213 formed on the upper cover 21. In this way, the opening / closing cover 4 rotates around the pivot shaft 213 while being held by the upper cover 21 (protective cover 2).

[0027] Thus, in this embodiment, the first holding portion 5 is formed by the pivot shaft 213 formed on the upper cover 21 (protective cover 2) and the pair of locking portions 43 formed on the opening / closing cover 4.

[0028] Furthermore, a locking frame 44 is formed on the other end of the peripheral wall 42 of the opening / closing cover 4 so as to protrude downward from the lower end of the peripheral wall 42 on the other end. By moving the opening / closing cover 4 parallel to the protective cover 2 in the direction normal to the opening 23a of the busbar exposure space 23, this locking frame 44 is locked into the locking hook 214 formed on the upper cover 21 (protective cover 2). In this embodiment, the locking hook 214 formed on the upper cover 21 (protective cover 2) and the locking frame 44 formed on the opening / closing cover 4 form the second holding portion 6.

[0029] This configuration allows the opening / closing cover 4 to rotate relative to the protective cover 2 without the need for a hinge. This prevents the opening / closing cover 4 from protruding too far from the protective cover 2.

[0030] This makes it possible to miniaturize the opening / closing cover 4, and more reliably prevent the opening / closing cover 4 from interfering with the adjacent part 7. As a result, it becomes possible to keep the adjacent part 7 as close to the opening / closing cover 4 as possible while suppressing interference between the opening / closing cover 4 and the adjacent part 7.

[0031] Furthermore, in this embodiment, the pivot shaft 213 is formed within the busbar exposure space 23. This ensures that the first holding portion 5 is located within the busbar exposure space 23 while the protective cover 2 is holding the opening / closing cover 4.

[0032] This prevents the first holding part 5 (rotation axis 213), which acts as the axis for rotating the opening / closing cover 4 relative to the protective cover 2, from protruding outside the opening / closing cover 4. As a result, interference between the opening / closing cover 4 and adjacent parts 7 can be more reliably prevented.

[0033] [Effects / Effects] The following describes the characteristic configuration of the busbar routing module shown in the above embodiment and the effects obtained therefrom.

[0034] The busbar routing module 1 shown in the above embodiment comprises a protective cover 2, busbars 3 routed to the protective cover 2, and a busbar exposure space 23 formed in the protective cover 2 in which a part of the busbars 3 is exposed. The busbar routing module 1 also comprises an opening / closing cover 4 that covers the opening 23a of the busbar exposure space 23. Furthermore, the busbar routing module 1 comprises a first holding part 5 that releasably holds one end of the opening / closing cover 4 to the protective cover 2, and a second holding part 6 that releasably holds the other end of the opening / closing cover 4 to the protective cover 2.

[0035] Here, the opening / closing cover 4 is configured such that, by moving it parallel to the normal direction of the opening 23a of the busbar exposure space 23 relative to the protective cover 2, one end is held by the protective cover 2 by the first holding part 5 and the other end is held by the protective cover 2 by the second holding part 6.

[0036] Furthermore, the opening / closing cover 4 is configured such that, while one end is held by the protective cover 2 by the first holding part 5, the other end is released from the protective cover 2 by the second holding part 6, allowing it to rotate relative to the protective cover 2 with the first holding part 5 as the axis.

[0037] As described above, in the busbar routing module 1 shown in the embodiment, the opening / closing cover 4 is moved parallel to the protective cover 2 in the direction normal to the opening 23a of the busbar exposure space 23, so that one end is held by the protective cover 2 by the first holding part 5. With one end held by the first holding part 5 by the protective cover 2, the cover 4 can be rotated relative to the protective cover 2 with the first holding part 5 as an axis.

[0038] This allows the opening / closing cover 4 to rotate relative to the protective cover 2 without the need for a hinge, thus preventing the opening / closing cover 4 from protruding too far from the protective cover 2.

[0039] As a result, it becomes possible to miniaturize the opening / closing cover 4, and it becomes possible to more reliably prevent the opening / closing cover 4 from interfering with adjacent parts 7.

[0040] Thus, by using the busbar routing module 1 shown in the above embodiment, it becomes possible to more reliably prevent the opening / closing cover 4, which is rotatably attached to the protective cover 2, from interfering with adjacent parts 7.

[0041] Alternatively, the first holding portion 5 may be positioned within the busbar exposure space 23 while the protective cover 2 is holding the opening / closing cover 4.

[0042] This prevents the first holding part 5, which acts as the axis for rotating the opening / closing cover 4 relative to the protective cover 2, from protruding outside the opening / closing cover 4. As a result, interference between the opening / closing cover 4 and adjacent parts 7 can be more reliably prevented.

[0043] [others] Although this embodiment has been described above, this embodiment is not limited to these, and various modifications are possible within the scope of the gist of this embodiment.

[0044] For example, in the above embodiment, a pivot shaft 213 is provided on the protective cover 2 side and a locking portion 43 is provided on the opening / closing cover 4 side as an example. However, the locking portion may be provided on the protective cover 2 side and the pivot shaft on the opening / closing cover 4 side. Alternatively, the pivot shaft and locking portion may be provided on the protective cover 2 side, and the corresponding locking portion and pivot shaft may be provided on the opening / closing cover 4 side. In this case, it is preferable that the pivot shaft on the protective cover 2 side and the pivot shaft on the opening / closing cover 4 side be aligned in a straight line when the opening / closing cover is attached to the protective cover.

[0045] Furthermore, it is possible to modify the protective cover, busbars, and other detailed specifications (shape, size, layout, etc.) as needed. [Explanation of Symbols]
