Description

[Technical Field]

[0001] The present invention relates to a bus bar routing module. [Background technology]

[0002] In vehicles such as electric vehicles and plug-in hybrid vehicles, bus bars are routed between stacks of batteries installed inside the vehicle, and a bus bar routing module is sometimes formed by attaching a protective cover to the bus bars (see, for example, Patent Document 1). The bus bar routing module (electrical junction box) described in Patent Document 1 has lower and upper covers made of synthetic resin, and inside these lower and upper covers, storage compartments are formed to house various electrical components. In addition, the electrical junction box and the batteries are electrically connected by a power line. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2006-166528 Summary of the Invention [Problem to be solved by the invention]

[0004] In the busbar routing module described above, the lower cover and upper cover are generally made of synthetic resin and molded by injection molding or the like, and these lower cover and upper cover have recesses to prevent the gate remainder from exceeding the outermost contour of the cover. The formation of these recesses creates thin-walled portions in the lower cover and upper cover that are thinner than the general portions, which can cause the molded product to break at the thin-walled portions when the molded product is removed from the injection molding die. Furthermore, the lower cover and upper cover sometimes have protrusions that sandwich and hold the busbars, which can create thick-walled portions in the lower cover and upper cover that are thicker than the general portions.

[0005] The present invention has been made in view of the problems inherent in the conventional technology, and an object of the present invention is to provide a bus bar routing module in which the lower cover and upper cover constituting the protective cover are free of thin and thick portions. [Means for solving the problem]

[0006] A busbar routing module according to an embodiment of the present invention includes a protective cover having a lower cover and an upper cover, and a busbar routed through the protective cover. The lower cover and the upper cover are formed with a recess so that the gate remainder does not exceed the outermost shape of the protective cover, and a protrusion located inside the recess for clamping and holding the busbar. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide a bus bar routing module in which the lower cover and upper cover constituting the protective cover are not formed with thin-walled portions and thick-walled portions. [Brief explanation of the drawings]

[Figure 2] FIG. 2 is an exploded perspective view of the bus bar wiring module according to the embodiment. [Figure 3] FIG. 2 is a plan view of the bus bar routing module according to the embodiment. [Figure 4] FIG. 4 is a cross-sectional view taken along line AA in FIG. DETAILED DESCRIPTION OF THE INVENTION

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

[0010] Fig. 1 is a schematic perspective view showing a busbar routing module 1 according to one embodiment. Fig. 2 is an exploded perspective view of the busbar routing module 1 shown in Fig. 1. Fig. 3 is a plan view of the busbar routing module 1 shown in Fig. 1. Fig. 4 is a cross-sectional view of the busbar routing module 1 shown in Fig. 1.

[0011] The busbar routing module 1 is installed in a vehicle such as an automobile and holds busbars 3 that are routed between stacks of high-voltage batteries for driving the automobile. The busbars 3 are conductive plate-like conductors made of a metal material such as copper or aluminum. There are no particular limitations on the shape or structure of the busbars 3 that are to be held by the busbar routing module 1.

[0012] The bus bar wiring module 1 has a protective cover 2 that is fixed to a panel (not shown) such as a body panel inside a vehicle. The protective cover 2 is made of synthetic resin molded by injection molding or the like, for example.

[0013] The busbar routing module 1 is supported by a panel (not shown). In the following drawings, the vertical direction in which the busbar routing module 1 is installed on the panel is defined as the Z direction. Two directions perpendicular to each other in an imaginary plane perpendicular to the Z direction are defined as the X direction and the Y direction. Of these, the Y direction is along the extension direction of the busbar 3 when attached.

[0014] The protective cover 2 is configured to have a lower cover 10, an upper cover 20, and a locking portion 4.

[0015] The lower cover 10 has an accommodating portion 5 that accommodates the bus bar 3. The lower cover 10 is formed in a U-shape in cross section, having a bottom wall portion 11 and a pair of lower side wall portions 12, 12. The pair of lower side wall portions 12, 12 each have an engaged portion 16 formed thereon that is engaged with an engaging portion 26, which will be described later.

[0016] A recess 14 is formed in the outer surface (lower surface) of the bottom wall portion 11 of the lower cover 10 so that the gate remnant 13 does not exceed the outermost shape of the lower cover 10 (see FIG. 4). That is, the entire gate remnant 13 is located within the recess 14 and is not exposed (protrudes) below the lower end of the recess 14. Furthermore, a protrusion 15 is formed in the inner surface (upper surface) of the bottom wall portion 11 of the lower cover 10, located inside the recess 14 (on the upper side in the illustrated example). The protrusion 15 sandwiches and holds the bus bar 3 together with a protrusion 25 of the upper cover 20, which will be described later. Note that the thickness (thickness in the Z direction) of the lower cover 10 at the locations where the recess 14 and the protrusion 15 are located is preferably approximately the same as the thickness of other locations (general portions) (see FIG. 4).

[0017] The upper cover 20 is connected to the lower cover 10 and covers the lower cover 10 (accommodating section 5). The upper cover 20 is formed in an inverted U-shape in cross section, and has a top wall section 21 and a pair of upper side wall sections 22, 22. The pair of upper side wall sections 22, 22 each have a locking section 26 to which the locked section 16 is locked.

[0018] A recess 24 is formed on the outer surface (top surface) of the top wall portion 21 of the upper cover 20 so that the gate remnant 23 does not exceed the outermost shape of the upper cover 20 (see FIG. 4). That is, the entire gate remnant 23 is located within the recess 24 and is not exposed (protrudes) above the upper end of the recess 24. Furthermore, a protrusion 25 is formed on the inner surface (bottom surface) of the top wall portion 21 of the upper cover 20, located inside the recess 24 (lower side in the illustrated example), and sandwiches and holds the bus bar 3 together with the protrusion 15 of the lower cover 10. Note that the thickness (thickness in the Z direction) of the upper cover 20 at the locations where the recess 24 and the protrusion 25 are located is preferably approximately the same as the thickness of other locations (general portions) (see FIG. 4).

[0019] The locking portion 4 is for locking the upper cover 20 to the lower cover 10. The locking portion 4 is configured to have a locking portion 26 formed on the upper cover 20 and a locked portion 16 formed on the lower cover 10 and locked by the locking portion 26.

[0020] In this embodiment, the locking portion 4 is provided on each side in the width direction (X direction) of the protective cover 2. However, this is not limited to this, and the locking portion 4 may be provided only on one side in the width direction of the protective cover 2, and the lower cover 10 and the upper cover 20 may be connected on the other side in the width direction by, for example, a hinge portion.

[0021] The upper cover 20 is placed over the opening side of the lower cover 10 and the locked portions 16 are locked to the locking portions 26, whereby the upper cover 20 is attached to the lower cover 10.

[0022] A protrusion 15 and a protrusion 25 are formed on the inner surface of the bottom wall 11 of the lower cover 10 and the inner surface of the top wall 21 of the upper cover 20, respectively. When the upper cover 20 is attached to the lower cover 10, the bus bar 3 is sandwiched and held down by the protrusions 15 and 25.

[0023] The following describes the effects of the bus bar routing module 1.

[0024] As described above, the busbar routing module 1 according to this embodiment includes the protective cover 2 including the lower cover 10 and the upper cover 20, and the busbar 3 routed through the protective cover 2. The lower cover 10 and the upper cover 20 are formed with recesses 14 and 24 that are provided so that the gate remains 13 and 23 do not exceed the outermost shape of the protective cover 2, and protrusions 15 and 25 that are positioned inside the recesses 14 and 24 and that sandwich and hold the busbar 3.

[0025] 4, in this embodiment, protrusions 15, 25 for sandwiching and holding the bus bar 3 are formed in positions inside the recesses 14, 24 in the lower cover 10 and the upper cover 20. Therefore, the plate thickness of the protective cover 2 at the locations where the recesses 14 and protrusions 15 are located can be set to be approximately the same as the plate thickness of the general portion, and the lower cover 10 and the upper cover 20 that constitute the protective cover 2 do not have thin portions or thick portions.

[0026] As described above, according to this embodiment, it is possible to provide the bus bar routing module 1 in which the lower cover 10 and the upper cover 20 constituting the protective cover 2 are not formed with thin-walled portions and thick-walled portions.

[0027] In the busbar routing module 1, the lower cover 10 may have a bottom wall portion 11 and a pair of lower side wall portions 12, 12, and the upper cover 20 may have a top wall portion 21 and a pair of upper side wall portions 22, 22. The bottom wall portion 11 of the lower cover 10 and the top wall portion 21 of the upper cover 20 may have recessed portions 14, 24 and protruding portions 15, 25, respectively.

[0028] 4, in this embodiment, convex portions 15, 25 for sandwiching and holding the bus bar 3 are formed in positions inside the concave portions 14, 24 on the bottom wall portion 11 of the lower cover 10 and the top wall portion 21 of the upper cover 20. Therefore, the plate thickness of the protective cover 2 at the locations where the concave portions 14 and the convex portions 15 are located can be set to be approximately the same as the plate thickness of the general portion, and the lower cover 10 and the upper cover 20 that constitute the protective cover 2 do not have thin portions or thick portions.

[0029] Although the present embodiment has been described above, the present embodiment is not limited to this, and various modifications are possible within the scope of the gist of the present embodiment. [Explanation of symbols]
