[0050] Hereinafter, an implementation mode of the bus bar holder according to the present invention will be described in detail with reference to the drawings. In addition, the present invention is not limited to this implementation mode.

[0051] [Implementation mode]

[0052] Based on Figures 1 to 5 An implementation mode of the bus bar holder according to the present invention will be described.

[0053] Figures 1 to 5 Reference numeral 1 in the drawings represents the bus bar holder of this implementation mode.

[0054] The bus bar holder 1 is a component for accommodating and holding a part of the first bus bar B1 covered by an insulating coating part and the second bus bar B2 covered by an insulating coating part ( Figure 4 and Figure 5 ), and is installed on the body of a vehicle such as an automobile. The bus bar holder 1 is formed of an insulating material such as synthetic resin. In addition, the first bus bar B1 and the second bus bar B2 are used for power distribution from a secondary battery of a vehicle, for example, one of them is used as the positive electrode side and the other is used as the negative electrode side.

[0055] The bus bar holder 1 has a holding body 10 for holding the straight parts B1a, B2a of the first bus bar B1 and the second bus bar B2 in parallel ( Figures 1 to 5)。The holding body 10 has: a first fitting accommodation chamber 10b that fits and accommodates the straight portion B1a of the first bus bar B1 inserted from the first insertion port 10a; and a second fitting accommodation chamber 10d that fits and accommodates the straight portion B2a of the second bus bar B2 inserted from the second insertion port 10c.

[0056] Specifically, the holding body 10 shown here has a first bottom wall 11, a pair of first side walls 12 vertically provided at intervals from the first bottom wall 11, a second bottom wall 13, and a pair of second side walls 14 vertically provided at intervals from the second bottom wall 13 ( Figures 1 to 3 ).

[0057] In the holding body 10, the first bottom wall 11, the pair of first side walls 12, the second bottom wall 13, and the pair of second side walls 14 are each formed in a rectangular flat plate shape. Also, in the holding body 10, the first bottom wall 11 and the second bottom wall 13 are arranged at intervals in the same plane, and the pair of first side walls 12 and the pair of second side walls 14 are arranged opposite to each other at intervals such that their planes face each other. The pair of first side walls 12 are vertically provided from the two side portions of the first bottom wall 11 with the two side portions of the first bottom wall 11 as fixed ends. In addition, the pair of second side walls 14 are vertically provided from the two side portions of the second bottom wall 13 with the two side portions of the second bottom wall 13 as fixed ends. Therefore, 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 accommodation chamber 10b. In the holding body 10, the first fitting accommodation chamber 10b is formed by the first bottom wall 11 and the pair of first side walls 12, so 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 accommodation chamber 10d. In the holding body 10, the second fitting accommodation chamber 10d is formed by the second bottom wall 13 and the pair of second side walls 14, so the rectangular opening on the free end side of the pair of second side walls 14 is used as the second insertion port 10c.

[0058] In the holding body 10 shown here, one first side wall 12 and one second side wall 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 to each other by a rectangular flat plate-shaped connecting wall 15 ( Figures 1 to 3 ).

[0059] The holding body 10 has a fixing portion 16 for fixing itself to the vehicle body ( Figure 3 and Figure 5)。The fixing portion 16 is provided on at least one outer wall surface of a first side wall 12 and a second side wall 14. For example, the fixing portion 16 can also be in any form such as a form in which a sheet portion provided on the vehicle body side is inserted and fitted, or a form in which it is screwed to the vehicle body side.

[0060] Moreover, the bus bar holder 1 has a first cover 20 and a second cover 30 ( Figures 1 to 5 ).

[0061] The first cover 20 is formed in a shape that closes the first insertion port 10a while leaving a part of the first insertion port 10a at the closed position ( Figure 2 ). In addition, the second cover 30 is formed in a shape that closes a part of the first insertion port 10a and closes the second insertion port 10c at the closed position ( Figure 3 ). The first cover 20 shown here closes the part of the rectangular first insertion port 10a except for both ends in the length direction at the closed position. And the second cover 30 shown here closes both ends in the length direction of the rectangular first insertion port 10a and the whole of the second insertion port 10c at the closed position.

[0062] A fitting groove 21 is formed in the first cover 20, and the end portion of the straight portion B1a of the first bus bar B1 accommodated in the first fitting accommodation chamber 10b is fitted into the fitting groove 21 at the closed position ( Figure 1 and Figure 4 ). In addition, a fitting groove 31A and a fitting groove 31B are formed in the second cover 30. The end portion of the straight portion B2a of the second bus bar B2 accommodated in the second fitting accommodation chamber 10d is fitted into the fitting groove 31A at the closed position, and the end portion of the straight portion B1a of the first bus bar B1 accommodated in the first fitting accommodation chamber 10b is fitted into the fitting groove 31B at the closed position ( Figure 1 , Figure 2 and Figure 4 ).

[0063] The first cover 20 shown here is formed in a rectangular flat plate shape ( Figure 1 , Figure 2 and Figure 4 ). In addition, the second cover 30 shown here is formed in a rectangular flat plate shape that can close the whole of the first insertion port 10a and the whole of the second insertion port 10c at the closed position, and covers the first cover 20 at the closed position at the closed position ( Figures 1 to 5 ). Therefore, a recess 32 into which the first cover 20 at the closed position is inserted is formed in the second cover 30 at the closed position ( Figure 1 , Figure 2 and Figure 4 ). The recess 32 is formed in a rectangle matching the shape of the first cover 20, and is inserted into the first cover 20 at the closed position to cover it from the outside.

[0064] The first cover 20 is connected to the holding body 10 via a first hinge portion 41 ( Figure 1 and Figure 4 ). The first hinge portion 41 connects the fixed end of the first cover 20 to a first side wall 12, holds the first cover 20 in a cantilever state, and enables opening and closing between the open position and the closed position of the first cover 20. The first hinge portion 41 shown here is formed as a so-called movable hinge. Here, first hinge portions 41 are provided at respective end portions in the longitudinal direction of the first cover 20.

[0065] The second cover 30 is connected to the holding body 10 via a second hinge portion 42 ( Figures 1 to 5 ). The second hinge portion 42 connects the fixed end of the second cover 30 to a second side wall 14, holds the second cover 30 in a cantilever state, and enables opening and closing between the open position and the closed position of the second cover 30. The second hinge portion 42 shown here is formed as a so-called movable hinge. Here, second hinge portions 42 are provided at respective end portions in the longitudinal direction of the second cover 30, and further two second hinge portions 42 are provided between the second hinge portions 42 at both ends.

[0066] Moreover, the bus bar holder 1 has: a first holding mechanism 50 that holds the first cover 20 in the closed position on the holding body 10; and a second holding mechanism 60 that holds the second cover 30 in the closed position on the holding body 10 ( Figure 1 、 Figure 2 and Figure 4 ).

[0067] The first holding mechanism 50 includes a first cover engaging portion 51 provided on the holding body 10 and a first cover engaged portion 52 provided at the free end of the first cover 20 ( Figure 1 、 Figure 2 and Figure 4 ). The first holding mechanism 50 holds the first cover 20 in the closed position on the holding body 10 by engaging the first cover engaging portion 51 with the first cover engaged portion 52 in the closed position. In the first holding mechanism 50 shown here, the peripheral portion of the through hole 15a provided in the connecting wall 15 is used as the first cover engaging portion 51, and for example, a claw portion of the first cover engaged portion 52 inserted into the through hole 15a in the closed position is hooked on the first cover engaging portion 51 to hold the first cover 20 in the closed position on the holding body 10.

[0068] The second holding mechanism 60 includes a second cover engaging portion 61 provided on the holding body 10 and a second cover engaged portion 62 provided at the free end of the second cover 30 ( Figure 1 、 Figure 2 and Figure 4)。The second holding mechanism 60 holds the second lid 30 at the closed position on the holding body 10 by engaging the second lid engaging portion 61 with the second lid engaged portion 62 at the closed position. In the second holding mechanism 60 shown here, the annular end face of the cylindrical portion 14a protruding from the outer wall surface of the other second side wall 14 is used as the second lid engaging portion 61, and the claw portion 62a of the second lid engaged portion 62 inserted into the cylindrical portion 14a is hooked on the second lid engaging portion 61 to hold the second lid 30 at the closed position on the holding body 10. The second holding mechanism 60 is provided at each end in the longitudinal direction of the second lid 30.

[0069] In the bus bar holder 1 shown above, when the first lid 20 and the second lid 30 are in the open position, the straight portion B1a of the first bus bar B1 is received in the first fitting receiving chamber 10b ( Figure 1 and Figure 4 ). And, in this bus bar holder 1, the first lid 20 is rotated to the closed position, and the first lid 20 is held at the closed position by the first holding mechanism 50 ( Figure 2 ). In addition, in Figure 2 , for the convenience of illustration, the first bus bar B1 is omitted. In addition, in Figure 4 , for the convenience of illustration, the straight portion B2a of the second bus bar B2 is also received in the second fitting receiving chamber 10d.

[0070] Next, in this bus bar holder 1, with the second lid 30 held in the open position, the straight portion B2a of the second bus bar B2 is received in the second fitting receiving chamber 10d ( Figure 4 ). And, in this bus bar holder 1, the second lid 30 is rotated to the closed position, and the second lid 30 is held at the closed position by the second holding mechanism 60 ( Figure 5 ).

[0071] In this bus bar holder 1, if the second bus bar B2 is to be removed when the first lid 20 and the second lid 30 are in the closed position, it is only necessary to open the second lid 30 to the open position. And, in this bus bar holder 1, if the first bus bar B1 is to be removed when the first lid 20 and the second lid 30 are in the closed position, it is necessary to open both the first lid 20 and the second lid 30 to the open position.

[0072] Thus, the bus bar holder 1 of the present embodiment can allow the bus bar to be removed as the removal target to be removed individually from a plurality of bus bars (the first bus bar B1, the second bus bar B2). Therefore, this bus bar holder 1 is useful in preventing misremoval of the bus bar to be removed. In addition, since this bus bar holder 1 can be used to remove a plurality of bus bars (the first bus bar B1, the second bus bar B2) one by one, it is possible to suppress energization caused by contact between the bus bars.

[0073] Moreover, in the bus bar holder 1, the second lid 30 in the closed position covers the first lid 20 in the closed position. Therefore, the first lid 20 cannot be opened unless the second lid 30 is opened. Thus, in the bus bar holder 1, if the first bus bar B1 is to be removed when the first lid 20 and the second lid 30 are in the closed position, the first lid 20 needs to be further opened to the open position after the second lid 30 is opened to the open position. Therefore, the bus bar holder 1 of the present embodiment can prevent misremoval of the bus bar to be removed in a more appropriate state and can suppress energization caused by contact between the bus bars in a more appropriate state.

[0074] In addition, the bus bar holder 1 of the present embodiment is assembled to the linear portions B1a and B2a of the first bus bar B1 and the second bus bar B2, respectively. Therefore, the bus bar holder 1 can be miniaturized in size. And the bus bar holder 1 can freely set the assembly position within the ranges of the linear portions B1a and B2a of the first bus bar B1 and the second bus bar B2, respectively. Therefore, the bus bar holder 1 of the present embodiment can easily follow the wiring paths of the bus bars in various vehicles and can have versatility.

[0075] In addition, the bus bar holder 1 of the present embodiment is assembled to the linear portions B1a and B2a of the first bus bar B1 and the second bus bar B2, respectively. Compared with the way of accommodating the entire first bus bar B1 and the second bus bar B2, it can reduce the number of the first holding mechanism 50 and the second holding mechanism 60 and improve the assembling workability with respect to the first bus bar B1 and the second bus bar B2.

[0076] In addition, the bus bar holder 1 of the present embodiment has an integral structure in which the first lid 20 and the second lid 30 are respectively connected to the holding body 10 via the first hinge portion 41 and the second hinge portion 42. Therefore, it can reduce the number of components and improve the assembling workability with respect to the first bus bar B1 and the second bus bar B2.

[0077] [Modification Example]

[0078] Figures 6 to 10 The reference numeral 2 of the bus bar holder represents the bus bar holder of this modification example. The bus bar holder 2 of this modification example is equivalent to replacing the first lid 20 and the second lid 30 in the bus bar holder 1 of the foregoing embodiment with the following first lid 120 and second lid 130 ( Figures 6 to 10 ). Therefore, in the bus bar holder 2 of this modification example, the same parts as those in the bus bar holder 1 of the embodiment are labeled with the same reference numerals as those in the embodiment, and the description thereof is omitted.

[0079] The first cover 120 of this modified example has a cover main body 121 formed in the same shape as the first cover 20 of the aforementioned embodiment. When the cover main body 121 in the closed position retains a part of the first insertion port 10a of the retainer 10 (both ends in the longitudinal direction of the first insertion port 10a), the first insertion port 10a is closed. Figures 6 to 10 )

[0080] Similar to the first cover 20 of the embodiment, the fixed end of the cover main body 121 is connected to one first side wall 12 of the retainer 10 via the first hinge portion 41. Figure 6 And Figure 9 ) Figures 6 to 10 ) Figure 6 And Figure 9 )

[0081] Similar to the second cover 30 of the aforementioned embodiment, the second cover 130 of this modified example is formed in a shape that closes a part of the end of the first insertion port 10a of the retainer 10 (both ends in the longitudinal direction of the first insertion port 10a) and closes the second insertion port 10c of the retainer 10 in the closed position. Figures 6 to 10 )

[0082] However, the second cover 130 of this modified example is different from the second cover 30 of the embodiment and has a cutout portion 130a into which the first cover 120 in the closed position is inserted in the closed position. Figures 6 to 10 ) Figures 6 to 10 )

[0083] The second cover 130 of this modification is similar to the second cover 30 of the embodiment. Its fixed end (fixed end of the main body 131) is connected to one second side wall 14 of the holder 10 via a second hinge portion 42 ( Figures 6 to 10 ). In addition, the second cover 130 has a second cover engaging portion 62 at its free end (the free end of each of the pair of sheet portions 132) similarly to the second cover 30 of the embodiment, and the second cover 130 is held by the holding body 10 by engaging the second cover engaging portion 61 of the holding body 10 with the second cover engaging portion 62 in the closed position ( Figures 6 to 10 ). In addition, the second cover 130 is formed similarly to the second cover 30 of the embodiment, with: a fitting groove 133A, in which the end of the straight portion B2a of the second bus bar B2 accommodated in the second fitting accommodation chamber 10d is inserted in the closed position; and a fitting groove 133B, in which the end of the straight portion B1a of the first bus bar B1 accommodated in the first fitting accommodation chamber 10b is inserted in the closed position ( Figure 6 , Figure 7 and Figure 9 ). The fitting groove 133A is formed in the main body portion 131. In addition, the fitting groove 133B is formed in each piece portion 132.

[0084] In the bus bar holder 2 of this modification, similarly to the bus bar 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 bus bar B1 is accommodated in the first fitting accommodation chamber 10b ( Figure 6 and Figure 9 ). In addition, in the bus bar holder 2, similarly to the bus bar holder 1 of the embodiment, the first cover 120 is rotated to the closed position, and the first cover 120 is held in the closed position by the first holding mechanism 50 ( Figure 7 ). In addition, Figure 7 In the figure, the first bus bar B1 is omitted for the convenience of illustration. Figure 9 In FIG. 1 , for convenience of illustration, the straight portion B2a of the second bus bar B2 is also accommodated in the second fitting accommodation chamber 10d.

[0085] Next, in the bus bar holder 2, similarly to the bus bar holder 1 of the embodiment, the straight portion B2a of the second bus bar B2 is accommodated in the second fitting accommodation chamber 10d ( Figure 9 ). In addition, in the bus bar holder 2, similarly to the bus bar holder 1 of the embodiment, the second cover 130 is rotated to the closed position, and the second cover 130 is held in the closed position by the second holding mechanism 60 ( Figure 10 ).

[0086] In the bus bar holder 2, similar to the bus bar holder 1 of the embodiment, if it is necessary to remove the second bus bar B2 when the first cover 120 and the second cover 130 are in the closed position, it is only necessary to open the second cover 130 to the open position. Further, in the bus bar holder 2, similar to the bus bar holder 1 of the embodiment, if the first bus bar B1 is removed when the first cover 120 and the second cover 130 are in the closed position, it is necessary to open both the first cover 120 and the second cover 130 to the open position.

[0087] Thus, similar to the bus bar holder 1 of the embodiment, the bus bar holder 2 of this modification can individually remove the bus bar to be removed from among a plurality of bus bars (the first bus bar B1 and the second bus bar B2). Therefore, the bus bar holder 2 is useful in preventing misremoval of the bus bar to be removed. Further, similar to the bus bar holder 1 of the embodiment, the bus bar holder 2 can allow a plurality of bus bars (the first bus bar B1 and the second bus bar B2) to be removed one by one, and thus can suppress energization caused by contact between the bus bars.

[0088] Here, in the bus bar holder 2, it may be configured similar to the bus bar holder 1 of the embodiment such that the first cover 120 cannot be opened unless the second cover 130 is opened. For example, in the bus bar holder 2, the locking portion 123 projects from the cover body 121 of the first cover 120 in the closed position toward a part of the end of the first insertion port 10a (both ends in the longitudinal direction of the first insertion port 10a) Figure 6 , Figure 7 and Figure 9) The piece portion 132 of the second lid 130 in the closed position covers the locking portion 123 in the closed position. Thus, in this bus bar holder 2, when the first lid 120 in the closed position is to be opened, the locking portion 123 is locked by the piece portion 132 of the second lid 130. Therefore, the first lid 120 in the closed position cannot be opened unless the second lid 130 in the closed position is opened. Thus, in this bus bar holder 2, similar to the bus bar holder 1 of the embodiment, if the first bus bar B1 is removed when the first lid 120 and the second lid 130 are in the closed position, it is necessary to further open the first lid 120 to the open position after opening the second lid 130 to the open position. Therefore, the bus bar holder 2 of this modified example, similar to the bus bar holder 1 of the embodiment, can prevent misremoval of the bus bar to be removed in a more appropriate state and can suppress energization caused by contact between the bus bars in a more appropriate state. Here, the two locking portions 123 protrude from one end in the length direction of the lid body 121 in the closed position toward one end in the length direction of the first insertion port 10a, and the two locking portions 123 protrude from the other end in the length direction of the lid body 121 in the closed position toward the other end in the length direction of the first insertion port 10a.

[0089] In addition, the bus bar holder 2 of this modified example, similar to the bus bar holder 1 of the embodiment, is assembled to the linear portions B1a and B2a of the first bus bar B1 and the second bus bar B2, respectively. Therefore, similar to the bus bar holder 1 of the embodiment, the bus bar holder 2 can achieve miniaturization of the body size, and can freely set the assembly position within the linear portions B1a and B2a of the first bus bar B1 and the second bus bar B2, respectively. Therefore, the bus bar holder 2 of this modified example, similar to the bus bar holder 1 of the embodiment, can easily follow the wiring paths of the bus bars in various vehicles and can have versatility.

[0090] In addition, the bus bar holder 2 of this modified example, similar to the bus bar holder 1 of the embodiment, is assembled to the linear portions B1a and B2a of the first bus bar B1 and the second bus bar B2, respectively.
