Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the conventional technique, all bus bars can be removed when one cover is opened, and there is room for improvement from the viewpoint of preventing misremoval of the bus bars to be removed.

[0005] Therefore, an object of the present invention is to provide a bus bar holder capable of individually removing a plurality of bus bars.

Means for Solving the Problems

[0006] The present invention comprises a holder that holds the straight portions of a first busbar and a second busbar, both covered with an insulating coating, running parallel to each other; a first cover connected to the holder via a first hinge; a second cover connected to the holder via a second hinge; a first holding mechanism that holds the first cover in a closed position on the holder; and a second holding mechanism that holds the second cover in a closed position on the holder. The holder has a first fitting chamber that accommodates the straight portion of the first busbar inserted through a first insertion opening; and a second fitting chamber that accommodates the straight portion of the second busbar inserted through a second insertion opening. The first cover is in a closed position. The aforementioned first insertion opening is left with a portion of the first insertion opening remaining The second cover is formed in a shape that closes, and in the closed position, it is characterized in that it closes a portion of the first insertion opening and also closes the second insertion opening. [Effects of the Invention]

[0007] In the busbar holder according to the present invention, if the second busbar is to be removed when the first and second covers are in the closed position, the second cover only needs to be opened to the open position. Conversely, in this busbar holder, if the first busbar is to be removed when the first and second covers are in the closed position, both the first and second covers need to be opened to the open position. Thus, the busbar holder according to the present invention allows for the individual removal of the busbar to be removed from among the first and second busbars. Therefore, this busbar holder is useful in preventing the mistaken removal of the wrong busbar. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0009] An embodiment of the busbar holder according to the present invention will be described in detail below with reference to the drawings. However, this embodiment does not limit the present invention.

[0010] [Embodiment] One embodiment of the busbar holder according to the present invention will be described with reference to Figures 1 to 5.

[0011] Reference numeral 1 in Figures 1 to 5 indicates the busbar holder of this embodiment.

[0012] The bus bar holder 1 is a member for accommodating and holding a part of the first bus bar B1 covered with an insulating coating and the second bus bar B2 covered with an insulating coating (Figs. 4 and 5), and is attached to the vehicle body of a vehicle such as an automobile. This bus bar holder 1 is formed of an insulating material such as synthetic resin. Incidentally, the first bus bar B1 and the second bus bar B2 are used, for example, for power distribution from a secondary battery of a vehicle, and one of them is used as the positive side and the other is used as the negative side.

[0013] The bus bar holder 1 has a holder 10 that holds the linear portions B1a and B2a of the first bus bar B1 and the second bus bar B2 side by side (Figs. 1 to 5). This holder 10 has a first fitting and accommodating chamber 10b that fits and accommodates the linear portion B1a of the first bus bar B1 inserted through the first insertion port 10a, and a second fitting and accommodating chamber 10d that fits and accommodates the linear portion B2a of the second bus bar B2 inserted through the second insertion port 10c.

[0014] Specifically, the holder 10 shown here has a first bottom wall 11, a pair of first side walls 12 vertically provided at intervals from this first bottom wall 11, a second bottom wall 13, and a pair of second side walls 14 vertically provided at intervals from this second bottom wall 13 (Figs. 1 to 3).

[0015] In this holding body 10, its first bottom wall 11, a pair of first side walls 12, second bottom wall 13, and a pair of second side walls 14 are each formed in a rectangular flat plate shape. And in this holding body 10, the first bottom wall 11 and the second bottom wall 13 are arranged on the same plane with a gap therebetween, and a pair of first side walls 12 and a pair of second side walls 14 are arranged opposite to each other with their planes facing each other and spaced apart. The pair of first side walls 12 have two side portions of the first bottom wall 11 as fixed ends and are perpendicularly provided from these two side portions respectively. Also, the pair of second side walls 14 have two side portions of the second bottom wall 13 as fixed ends and are perpendicularly provided from these two side portions respectively. Thus, the holding body 10 has a rectangular parallelepiped-shaped space surrounded by the first bottom wall 11 and the pair of first side walls 12, and this space is used as the first fitting and accommodating chamber 10b. In this holding body 10, since the first bottom wall 11 and the pair of first side walls 12 form the first fitting and accommodating chamber 10b, the rectangular opening on the free end side of the pair of first side walls 12 is used as the first insertion port 10a. Also, the holding body 10 has a rectangular parallelepiped-shaped space surrounded by the second bottom wall 13 and the pair of second side walls 14, and this space is used as the second fitting and accommodating chamber 10d. In this holding body 10, since the second bottom wall 13 and the pair of second side walls 14 form the second fitting and accommodating chamber 10d, the rectangular opening on the free end side of the pair of second side walls 14 is used as the second insertion port 10c.

[0016] In the holding body 10 shown here, one of the first side walls 12 and one of the second side walls 14 are arranged on the outer wall side, and the free ends of the other first side wall 12 and the other second side wall 14 on the inner wall side are connected by a rectangular flat plate-shaped connecting wall 15 (FIGS. 1 to 3).

[0017] This holding body 10 has a fixing portion 16 for fixing itself to the vehicle body (FIGS. 3 and 5). This fixing portion 16 is provided on at least one of the outer wall surfaces of one of the first side walls 12 and one of the second side walls 14. For example, the fixing portion 16 may adopt any form such as one that inserts and fits a piece provided on the vehicle body side, one that is screwed and fixed to the vehicle body side, etc.

[0018] Furthermore, the bus holder 1 has a first cover 20 and a second cover 30 (Figures 1 to 5).

[0019] The first cover 20 is formed in a shape that closes the first insertion opening 10a, leaving a portion open when in the closed position (Figure 2). The second cover 30 is formed in a shape that closes a portion of the first insertion opening 10a and also closes the second insertion opening 10c when in the closed position (Figure 3). The first cover 20 shown here closes the portion of the rectangular first insertion opening 10a excluding both ends in the longitudinal direction when in the closed position. The second cover 30 shown here closes both ends in the longitudinal direction of the rectangular first insertion opening 10a and the entire second insertion opening 10c when in the closed position.

[0020] The first cover 20 has a fitting groove 21 into which the end of the straight section B1a of the first busbar B1 housed in the first fitting chamber 10b is fitted in the closed position (Figures 1 and 4). The second cover 30 has a fitting groove 31A into which the end of the straight section B2a of the second busbar B2 housed in the second fitting chamber 10d is fitted in the closed position, and a fitting groove 31B into which the end of the straight section B1a of the first busbar B1 housed in the first fitting chamber 10b is fitted in the closed position (Figures 1, 2 and 4).

[0021] The first cover 20 shown here is formed in the shape of a rectangular flat plate (Figures 1, 2, and 4). The second cover 30 shown here is also formed in the shape of a rectangular flat plate that can completely cover the entire first insertion opening 10a and the entire second insertion opening 10c in the closed position, and covers the first cover 20 in the closed position (Figures 1 to 5). The second cover 30 has a recess 32 into which the first cover 20 in the closed position is fitted (Figures 1, 2, and 4). This recess 32 is formed in the shape of a rectangle that matches the shape of the first cover 20, and in the closed position the first cover 20 is fitted into it and covers it from the outside.

[0022] The first cover 20 is connected to the holder 10 via a first hinge portion 41 (Figures 1 and 4). This first hinge portion 41 connects the fixed end of the first cover 20 to one of the first side walls 12, holding the first cover 20 in a cantilevered state, and enabling opening and closing between the open and closed positions of the first cover 20. The first hinge portion 41 shown here is formed as a so-called living hinge. Here, the first hinge portion 41 is provided at each end of the first cover 20 in the longitudinal direction.

[0023] The second cover 30 is connected to the holder 10 via a second hinge portion 42 (Figures 1 to 5). This second hinge portion 42 connects the fixed end of the second cover 30 to one of the second side walls 14, holding the second cover 30 in a cantilevered state, and enabling opening and closing between the open and closed positions of the second cover 30. The second hinge portion 42 shown here is formed as a so-called living hinge. Here, a second hinge portion 42 is provided at each end in the longitudinal direction of the second cover 30, and two more second hinge portions 42 are provided between these two second hinge portions 42.

[0024] Furthermore, the busbar holder 1 includes a first holding mechanism 50 that holds the first cover 20 in the closed position on the holder 10, and a second holding mechanism 60 that holds the second cover 30 in the closed position on the holder 10 (Figures 1, 2, and 4).

[0025] The first holding mechanism 50 comprises a first cover engaging portion 51 provided on the holder 10 and a first cover engagement portion 52 provided on the free end of the first cover 20 (Figures 1, 2, and 4). The first holding mechanism 50 holds the first cover 20 on the holder 10 in the closed position by engaging the first cover engaging portion 51 and the first cover engagement portion 52 in the closed position. In the first holding mechanism 50 shown here, the peripheral edge of the through hole 15a provided in the connecting wall 15 is used as the first cover engaging portion 51, and the claw portion of the first cover engagement portion 52, which is inserted into the through hole 15a in the closed position, is hooked onto the first cover engaging portion 51 to hold the first cover 20 on the holder 10 in the closed position.

[0026] The second retaining mechanism 60 comprises a second cover engaging portion 61 provided on the retaining body 10 and a second cover engagement portion 62 provided on the free end of the second cover 30 (Figures 1, 2, and 4). The second retaining mechanism 60 holds the second cover 30 in the closed position on the retaining body 10 by engaging the second cover engaging portion 61 and the second cover engagement portion 62 in the closed position. In the second retaining mechanism 60 shown here, the annular end face of the cylindrical portion 14a that bulges out from the outer wall surface of the other second side wall 14 is used as the second cover engaging portion 61, and the claw portion 62a of the second cover engagement portion 62 inserted into the cylindrical portion 14a is hooked onto the second cover engaging portion 61 to hold the second cover 30 in the closed position on the retaining body 10. This second retaining mechanism 60 is provided at each end in the longitudinal direction of the second cover 30.

[0027] In the busbar holder 1 described above, when the first cover 20 and the second cover 30 are in the open position, the straight portion B1a of the first busbar B1 is housed in the first fitting chamber 10b (Figures 1 and 4). Then, in this busbar holder 1, the first cover 20 is rotated to the closed position and the first holding mechanism 50 keeps the first cover 20 in the closed position (Figure 2). Note that in Figure 2, the first busbar B1 is omitted for illustrative purposes. Also, in Figure 4, for illustrative purposes, the straight portion B2a of the second busbar B2 is also housed in the second fitting chamber 10d.

[0028] Next, in this busbar holder 1, the straight portion B2a of the second busbar B2 is housed in the second fitting chamber 10d while the second cover 30 is kept in the open position (Figure 4). Then, in this busbar holder 1, the second cover 30 is rotated to the closed position and the second holding mechanism 60 holds the second cover 30 in the closed position (Figure 5).

[0029] In this busbar holder 1, if the second busbar B2 is to be removed when the first cover 20 and the second cover 30 are in the closed position, the second cover 30 only needs to be opened to the open position. However, in this busbar holder 1, if the first busbar B1 is to be removed when the first cover 20 and the second cover 30 are in the closed position, both the first cover 20 and the second cover 30 need to be opened to the open position.

[0030] As described above, the busbar holder 1 of this embodiment allows for the individual removal of the busbar to be removed from among multiple busbars (first busbar B1, second busbar B2). Therefore, this busbar holder 1 is useful in preventing the mistaken removal of the wrong busbar. Furthermore, since this busbar holder 1 allows for the removal of multiple busbars (first busbar B1, second busbar B2) one by one, it can suppress the conduction of current due to contact between the busbars.

[0031] Furthermore, in this busbar holder 1, the first cover 20 in the closed position is covered by the second cover 30 in the closed position, so the first cover 20 cannot be opened without opening the second cover 30. Therefore, in this busbar holder 1, if the first busbar B1 is to be removed when the first cover 20 and the second cover 30 are in the closed position, the second cover 30 must be opened to the open position, and then the first cover 20 must be opened to the open position. Accordingly, the busbar holder 1 of this embodiment can more effectively prevent the misidentification of the busbar to be removed, and can more effectively suppress the conduction of current due to contact between busbars.

[0032] Furthermore, the bus bar holder 1 of this embodiment is designed to be attached to the straight sections B1a and B2a of the first bus bar B1 and the second bus bar B2, respectively. Therefore, the bus bar holder 1 can be made smaller in size. Moreover, the bus bar holder 1 can be freely attached within the range of the straight sections B1a and B2a of the first bus bar B1 and the second bus bar B2, respectively. Consequently, the bus bar holder 1 of this embodiment can be easily adapted to the routing paths of bus bars in various vehicles, thus providing versatility.

[0033] Furthermore, the busbar holder 1 of this embodiment is designed to be assembled to the straight sections B1a and B2a of the first busbar B1 and the second busbar B2, respectively. Compared to a design that accommodates the entirety of the first busbar B1 and the second busbar B2, this design allows for a reduction in the number of first and second holding mechanisms 50 and 60, as well as improved assembly workability for the first and second busbars B1 and B2.

[0034] Furthermore, the busbar holder 1 of this embodiment has an integrated structure in which the first cover 20 and the second cover 30 are connected to the holder 10 via the first hinge portion 41 and the second hinge portion 42, respectively, which makes it possible to reduce the number of parts and improve the ease of assembly for the first busbar B1 and the second busbar B2.

[0035] [Differentiation] Reference numeral 2 in Figures 6 to 10 indicates the busbar holder of this modified example. The busbar holder 2 of this modified example corresponds to the busbar holder 1 of the embodiment described above, in which the first cover 20 and the second cover 30 are replaced with the first cover 120 and the second cover 130 described below (Figures 6 to 10). Therefore, in the busbar holder 2 of this modified example, the same reference numerals as in the embodiment are used for the same parts as in the busbar holder 1 of the embodiment, and their descriptions are omitted.

[0036] The first cover 120 of this modified example has a cover body 121 formed in the same shape as the first cover 20 of the embodiment described above, and the cover body 121 in the closed position closes the first insertion opening 10a of the holder 10, leaving a portion of it (both ends in the longitudinal direction of the first insertion opening 10a) open (Figures 6 to 10).

[0037] The cover body 121, like the first cover 20 in the embodiment, has its fixed end connected to one of the first side walls 12 of the holder 10 via a first hinge portion 41 (Figures 6 and 9). Also, like the first cover 20 in the embodiment, the cover body 121 has a first cover engagement portion 52 at its free end, and is held by the holder 10 by engaging this first cover engagement portion 52 with the first cover engagement portion 51 of the holder 10 in the closed position (Figures 6 to 10). Furthermore, like the first cover 20 in the embodiment, the cover body 121 has a fitting groove 122 into which the end of the straight portion B1a of the first busbar B1 housed in the first fitting chamber 10b is fitted in the closed position (Figures 6 and 9).

[0038] In this modified example, the second cover 130 is formed in the same way as the second cover 30 in the embodiment described above, so as to close a portion of the front of the first insertion opening 10a of the holder 10 (both ends in the longitudinal direction of the first insertion opening 10a) and also closes the second insertion opening 10c of the holder 10 when in the closed position (Figures 6 to 10).

[0039] However, unlike the second cover 30 of the embodiment, the second cover 130 of this modified example has a notch 130a into which the first cover 120 in the closed position is fitted when the cover is closed (Figures 6 to 10). This second cover 130 is formed to have a shape having a main body 131 that closes the second insertion opening 10c and a piece 132 that protrudes from the main body 131 and closes a part of the front of the first insertion opening 10a (both ends in the longitudinal direction of the first insertion opening 10a) (Figures 6 to 10). In this second cover 130, the notch 130a is provided adjacent to the main body 131 and the piece 132. The main body 131 shown here is formed in the shape of a rectangular flat plate. The piece 132 shown here is also formed in the shape of a rectangular flat plate and protrudes from both ends in the longitudinal direction of the main body 131. The notch 130a is positioned between the pair of pieces 132.

[0040] In this modified example, the second cover 130, like the second cover 30 in the embodiment, has its fixed end (the fixed end on the main body 131) connected to one of the second side walls 14 of the holder 10 via a second hinge portion 42 (Figures 6 to 10). Also, like the second cover 30 in the embodiment, this second cover 130 has a second cover engagement portion 62 at its free end (each free end of the pair of piece portions 132), and is held by the holder 10 by engaging this second cover engagement portion 62 with the second cover engagement portion 61 of the holder 10 in the closed position (Figures 6 to 10). Furthermore, the second cover 130, like the second cover 30 of the embodiment, has a fitting groove 133A into which the end of the straight portion B2a of the second busbar B2 housed in the second fitting chamber 10d is fitted in the closed position, and a fitting groove 133B into which the end of the straight portion B1a of the first busbar B1 housed in the first fitting chamber 10b is fitted in the closed position (Figures 6, 7, and 9). The fitting groove 133A is formed in the main body 131, and the fitting groove 133B is formed in each of the pieces 132.

[0041] In this modified busbar holder 2, similar to the busbar holder 1 of the embodiment, when the first cover 120 and the second cover 130 are in the open position, the straight portion B1a of the first busbar B1 is housed in the first fitting chamber 10b (Figures 6 and 9). In this busbar holder 2, similar to the busbar holder 1 of the embodiment, the first cover 120 is rotated to the closed position and the first holding mechanism 50 keeps the first cover 120 in the closed position (Figure 7). Note that in Figure 7, the first busbar B1 is omitted for illustrative purposes. Also, in Figure 9, for illustrative purposes, the straight portion B2a of the second busbar B2 is also housed in the second fitting chamber 10d.

[0042] Next, in this busbar holder 2, just like in the busbar holder 1 of the embodiment, the straight portion B2a of the second busbar B2 is housed in the second fitting chamber 10d while the second cover 130 is kept in the open position (Figure 9). Then, in this busbar holder 2, just like in the busbar holder 1 of the embodiment, the second cover 130 is rotated to the closed position and the second holding mechanism 60 holds the second cover 130 in the closed position (Figure 10).

[0043] In this busbar holder 2, just like in the busbar holder 1 of the embodiment, if the second busbar B2 is to be removed when the first cover 120 and the second cover 130 are in the closed position, then the second cover 130 only needs to be opened to the open position. And in this busbar holder 2, just like in the busbar holder 1 of the embodiment, if the first busbar B1 is to be removed when the first cover 120 and the second cover 130 are in the closed position, then both the first cover 120 and the second cover 130 need to be opened to the open position.

[0044] Thus, the busbar holder 2 of this modified example, like the busbar holder 1 of the embodiment, allows for the individual removal of the busbar to be removed from among multiple busbars (first busbar B1, second busbar B2). Therefore, this busbar holder 2 is useful in preventing the mistaken removal of the wrong busbar. Furthermore, since this busbar holder 2 allows for the removal of multiple busbars (first busbar B1, second busbar B2) one by one, just like the busbar holder 1 of the embodiment, it can suppress the conduction of current due to contact between the busbars.

[0045] Here, in this busbar holder 2, it may be configured such that the first cover 120 cannot be opened unless the second cover 130 is opened, similar to the busbar holder 1 of the embodiment. For example, in this busbar holder 2, a locking portion 123 is made to protrude from the cover body 121 of the first cover 120 in the closed position toward a part of the front of the first insertion opening 10a (both ends in the longitudinal direction of the first insertion opening 10a) (Figures 6, 7, and 9), and this locking portion 123 in the closed position is covered by a piece 132 of the second cover 130 in the closed position. As a result, in this busbar holder 2, when attempting to open the first cover 120 in the closed position, the locking portion 123 is locked by the piece 132 of the second cover 130, so the first cover 120 in the closed position cannot be opened unless the second cover 130 in the closed position is opened. Therefore, in this busbar holder 2, just like the busbar holder 1 of the embodiment, if the first busbar B1 is to be removed when the first cover 120 and the second cover 130 are in the closed position, it is necessary to open the second cover 130 to the open position and then open the first cover 120 to the open position. Accordingly, the busbar holder 2 of this modified version, just like the busbar holder 1 of the embodiment, can more effectively prevent the misidentification of the busbar to be removed and can more effectively suppress the conduction of current due to contact between busbars. Here, two locking portions 123 protrude from one longitudinal end of the cover body 121 in the closed position toward one longitudinal end of the first insertion opening 10a, and two locking portions 123 protrude from the other longitudinal end of the cover body 121 in the closed position toward the other longitudinal end of the first insertion opening 10a.

[0046] Furthermore, the bus bar holder 2 of this modified version is assembled to the straight sections B1a and B2a of the first bus bar B1 and the second bus bar B2, respectively, just like the bus bar holder 1 of the embodiment. Therefore, the bus bar holder 2 can be made smaller in size, just like the bus bar holder 1 of the embodiment, and the assembly position can be freely set within the range of the straight sections B1a and B2a of the first bus bar B1 and the second bus bar B2, respectively. Consequently, the bus bar holder 2 of this modified version can be easily adapted to the routing paths of bus bars in various vehicles, just like the bus bar holder 1 of the embodiment, thus providing versatility.

[0047] Furthermore, the busbar holder 2 in this modified example is assembled to the straight sections B1a and B2a of the first busbar B1 and the second busbar B2, respectively, just like the busbar holder 1 in the embodiment. Compared to one that accommodates the entirety of the first busbar B1 and the second busbar B2, this allows for a reduction in the number of first holding mechanisms 50 and second holding mechanisms 60, as well as improved assembly workability for the first busbar B1 and the second busbar B2.

[0048] Furthermore, the busbar holder 2 of this modified example adopts an integrated structure in which the first cover 120 and the second cover 130 are connected to the holder 10 via the first hinge portion 41 and the second hinge portion 42, respectively, just like the busbar holder 1 of the embodiment. This makes it possible to reduce the number of parts and improve the ease of assembly for the first busbar B1 and the second busbar B2. [Explanation of Symbols]
