DETAILED DESCRIPTION

[0036] In order to make the technical scheme in the utility model better understood by the person skilled in the art, the technical scheme in the utility model embodiments will be clearly and completely described below in combination with the drawings in the utility model embodiments. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the utility model.

[0037] As described in the background, the busbar support of the integrated busbar in the prior art is a separation plate, and the size of the support is the size of a separation plate. However, the number of battery cells in different battery packs is different, which leads to the different size of the support in the busbar. Therefore, the size of the separation plate needs to be customized according to the demand, which leads to the need of new molds for processing and producing the separation plate each time, and thus the production cost of the integrated busbar is increased and the production efficiency is decreased.

[0038] The integrated busbar of the utility model comprises a busbar support; the busbar support comprises a plurality of sequentially connected separation plates, and among the two adjacent separation plates, a first clamping part is arranged on one separation plate, and a second clamping part clamped with the first clamping part is arranged on the other separation plate.

[0039] It can be understood that the busbar support of the integrated busbar in the prior art is an integral structure or formed by only one separation plate, while the utility model is formed by a plurality of separation plates sequentially clamped and fixed along the first direction to form a busbar support. The utility model can select a corresponding number of separation plates for splicing according to the different number and size of battery cells, thereby saving the number of molds for producing the separation plates, improving the production efficiency, and reducing the production cost.

[0040] In addition, the connection mode of sequentially clamping the plurality of separation plates can not only ensure the connection stability and connection strength between the plurality of separation plates, facilitate the transfer and transportation in the production process, but also can make the connected plurality of separation plates hardly shake relatively, so as to ensure the consistency when some holes or mounting structures on the separation plates are connected with the mounting structures on other components, that is, the holes or mounting structures on the separation plates can be easily aligned with the mounting structures on other components, and deviation is not easy to occur, thereby realizing the installation of the integrated busbar and other components.

[0041] For example, when the busbar support is composed of two separation plates, the busbar support comprises a first separation plate and a second separation plate clamped; when the busbar support is composed of three or more separation plates, the busbar support comprises a first separation plate, a second separation plate, and at least one third separation plate sequentially connected between the first separation plate and the second separation plate.

[0042] Embodiment 1

[0043] As Figures 1-6As shown, the busbar support 1 of the embodiment includes a first isolation plate 11 and a second isolation plate 12, the first isolation plate 11 is provided with a first clamping part 111, the second isolation plate 12 is provided with a second clamping part 122, and the first clamping part 111 and the second clamping part 122 are clamped and fixed.

[0044] Specifically, as shown, Figure 4 The first clamping part 111 includes a first clamping body 1111 extending outward from one side of the first isolation plate 11 in a first direction, and the distal end of the first clamping body 1111 is provided with a first clamping hook 1112; the second clamping part 122 includes a second clamping body 1221 extending outward from one side of the second isolation plate 12 in the first direction, and the distal end of the second clamping body 1221 is provided with a second clamping hook 1222; the first clamping hook 1112 and the second clamping hook 1222 are clamped with each other. The distal end of the first clamping body 1111 is one end of the first clamping body 1111 facing the second isolation plate 12; the distal end of the second clamping body 1221 is one end of the second clamping body 1221 facing the first isolation plate 11.

[0045] Further, one side of the first isolation plate 11 is provided with a first groove 112, and the first clamping body 1111 is located at the first groove 112; one side of the second isolation plate 12 is provided with a second groove 121, and the second clamping body 1221 is located at the second groove 121. In this way, when the first isolation plate 11 and the second isolation plate 12 are connected, one side of the first isolation plate 11 and one side of the second isolation plate 12 abut, ensuring the stability of the connection between the first isolation plate 11 and the second isolation plate 12.

[0046] Preferably, the end of the first clamping body 1111 and the end of the second clamping body 1221 in the embodiment can be provided with a guide surface, facilitating the mutual insertion of the two.

[0047] Further, in the embodiment, the length of the first clamping body 1111 in the connection direction of the first isolation plate 11 and the second isolation plate 12 is greater than or equal to the depth of the first groove 112; and / or, the length of the second clamping body 1221 in the connection direction of the first isolation plate 11 and the second isolation plate 12 is greater than or equal to the depth of the second groove 121.

[0048] Specifically, the length of the first clamping body 1111 is greater than the depth of the first groove 112, and the length of the second clamping body 1221 is greater than the depth of the second groove 121; when the first isolation plate 11 and the second isolation plate 12 are connected, part of the first clamping body 1111 is located in the second groove 121, and part of the second clamping body 1221 is located in the first groove 112.

[0049] The first isolation plate 11 in the embodiment is further provided with a plurality of first clamping portions 111 on one side, and the second isolation plate 12 is provided with a plurality of second clamping portions 122 corresponding to the first clamping portions 111 on one side. In this way, the connection stability and strength of the first isolation plate 11 and the second isolation plate 12 can be further enhanced.

[0050] As shown in the drawings, Figure 5 two first limiting blocks 115 extend outwardly along the first direction in the first recess 112, and a second limiting block 125 extends outwardly along the first direction in the second recess 121. The two first limiting blocks 115 are provided with a limiting space, and the second limiting block 125 is inserted into the limiting space, thereby achieving the limiting effect of the first isolation plate 11 and the second isolation plate 12 in the distribution direction of the two first limiting blocks 115.

[0051] It can be understood that at least part of the two first limiting blocks 115 is located in the first recess 112, and at least part of the second limiting block 125 is located in the second recess 121. In the embodiment, when the second limiting block 125 is inserted into the limiting space, part of the first limiting block 115 is located in the second recess 121, and part of the second limiting block 125 is located in the first recess 112. The insertion and cooperation of the second limiting block 125 and the limiting space achieve the limiting effect of the first clamping portion 111 and the second clamping portion 122.

[0052] Further, as shown in the drawings, Figure 5 a limiting member 116 extends outwardly along the first direction in the first recess 112, and the limiting member 116 and the first clamping body 1111 are distributed in parallel. A bottom plate 126 extends outwardly along the first direction in the second recess 121, and the bottom plate 126 and the second clamping body 1221 are distributed in parallel along the first direction with a gap 127. The limiting member 116 is inserted into the gap 127, and the limiting member 116 is limited from the distribution direction of the bottom plate 126 and the second clamping body 1221, thereby achieving the limiting effect of the first isolation plate 11 and the second isolation plate 12.

[0053] In the embodiment, one side of the first isolation plate 11 is provided with a recessed portion 113 along the first direction, and one side of the second isolation plate 12 is provided with a protruding portion 123. When the first isolation plate 11 and the second isolation plate 12 are connected, the protruding portion 123 is inserted into the recessed portion 113, which can limit the relative shaking of the two isolation plates in the direction perpendicular to the first direction, for example Figure 2 the first direction in the drawings is the up-down direction, and the protruding portion 123 and the recessed portion 113 can limit the relative shaking of the two isolation plates in the left-right direction.

[0054] Furthermore, the recessed portion 113 is provided with a first engaging portion 111, and the protruding portion 123 is provided with a second engaging portion 122. This arrangement can further enhance the connection stability and connection strength between the first isolation plate 11 and the second isolation plate 12.

[0055] Preferably, the width of the recess 113 is slightly greater than the width of the protrusion 123, and the depth of the recess 113 is slightly greater than the length of the protrusion 123, thereby providing a certain tolerance to facilitate the insertion of the recess 113 and the protrusion 123.

[0056] like Figures 1-3 As shown, in this embodiment, the second isolation plate 12 is provided with a limiting baffle 124, and the limiting baffle 124 and the second isolation plate 12 form a limiting cavity 128. A limiting post 114 extending outward along a first direction is provided on one side of the first isolation plate 11, and the limiting post 114 is inserted into the limiting cavity 128 along the first direction. After the limiting post 114 is inserted into the limiting cavity 128, the inner wall of the limiting cavity 128, i.e., the limiting baffle 124 and the second isolation plate 12, can restrict the movement of the limiting post 114 within the limiting cavity 128, thereby limiting the first isolation plate 11 and the second isolation plate 12, and thus enhancing the connection stability and connection strength of the isolation plate 11 and the second isolation plate 12.

[0057] It should be understood that this embodiment is illustrated by taking the example of a recess 113 and a limiting post 114 provided on the first isolation plate 11, and a protrusion 123 and a limiting baffle 124 provided on the second isolation plate 12. In other embodiments, the positions of the recess 113 and the protrusion 123, and the limiting post 114 and the limiting baffle 124 can be interchanged, and the number is not limited. Any technical solution that can enhance the connection stability and connection strength of the two isolation plates 11 and 12 is within the scope of protection of this utility model.

[0058] like Figures 1-7 As shown, both the first isolation plate 11 and the second isolation plate 12 are provided with cable trays 14, and both sides of the cable trays 14 are provided with connection holes 15. The integrated busbar also includes several electrical connectors 2, acquisition harnesses 3 and wire baffles 4. The electrical connectors 2 are installed on the busbar support 1, the acquisition harnesses 3 are electrically connected to the electrical connectors 2, and a portion of the acquisition harnesses 3 is housed in the cable trays 14. The wire baffles 4 include a baffle portion 41 and a connecting portion 42 bent from opposite sides of the baffle portion 41. The wire baffles 4 cover the cable trays 14, and the connecting portion 42 is snapped and fixed with the connection holes 15.

[0059] The electrical connection can be made by welding, that is, the electrical connector 2 can be installed on the isolation plates on both sides of the acquisition harness 3.

[0060] Further, the connecting portion 42 is an elastic connecting portion 42, that is, when the connecting portion 42 is clamped with the connecting hole 15, the connecting portion 42 can be deformed by pressing one end of the connecting portion 42, so that the clamping of the connecting portion 42 with the connecting hole 15 is released, and thus the baffle plate 4 can be removed from the isolation plate, thereby facilitating the installation and removal of the baffle plate 4 and the isolation plate.

[0061] As shown in Figure 2 , the first isolation plate 11 and the second isolation plate 12 are both provided with a positioning hole 16 for accommodating the electrode post of the battery cell, and the electrical connecting piece 2 is electrically connected with the electrode post accommodated in the positioning hole 16. Preferably, the positioning hole 16 in the embodiment is a square hole.

[0062] As shown in Figure 6 , the first isolation plate 11 and the second isolation plate 12 in the embodiment are both provided with a plurality of mica plate mounting holes 17, and the mica plate 5 is also provided with a plurality of isolation plate mounting holes 51. Since the first isolation plate 11 and the second isolation plate 12 are fixed by clamping of the first clamping portion 111 and the second clamping portion 122, the mica plate mounting holes 17 on the first isolation plate 11 and the second isolation plate 12 can correspond to the isolation plate mounting holes 51 on the mica plate 5 one by one, and will not be dislocated. The first isolation plate 11, the second isolation plate 12 and the mica plate 5 can be fixed and installed by cooperation of bolts or other components with the isolation plate mounting holes 51 and the mica plate mounting holes 17. Since the mica plate mounting holes 17 and the isolation plate mounting holes 51 are consistent, the installation efficiency and convenience of the busbar support 1 and the mica plate 5 are improved.

[0063] As shown in Figures 1-6 , the first isolation plate 11 and the second isolation plate 12 in the embodiment are both provided with a plurality of electrical connecting holes 18 for accommodating the electrode post of the battery cell, and the electrical connecting piece 2 is arranged at the electrical connecting hole 18 and is electrically connected with the electrode post. The electrical connecting piece 2 can be provided with a hole, and the first isolation plate 11 and the second isolation plate 2 are provided with a connecting column 19 inserted into the hole. When the hole of the electrical connecting piece 2 is inserted with the connecting column 19, the connecting column 19 can be deformed by using a hot riveting process, so that the size of the connecting column 19 is greater than the hole diameter of the hole on the electrical connecting piece 2, thereby realizing stable connection of the electrical connecting piece 2 with the first isolation plate 11 and the second isolation plate 2.
