The term "and / or" used in this utility model includes any and all combinations of one or more related listed items.

[0035] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0036] Please refer to Figures 1 to 3 The embodiment of the utility model provides a copper bar fixing structure 20, which is an insulating component and is used to fix multiple copper bars 10 to form a whole.

[0037] For the convenience of explanation, a coordinate system XYZ is established, which represents a first direction X, a second direction Y, and a third direction Z, respectively. The three directions intersect with each other, and further, the three directions may be perpendicular to each other.

[0038] The copper bar fixing structure 20 includes a fixing section 21 and an isolating section 22. The fixing section 21 is suitable for connecting a plurality of copper bars 10 spaced apart from each other. The isolating section 22 is connected to the fixing section 21 and is suitable for covering at least one copper bar 10 close to a housing (not shown) of the electrical device among the plurality of copper bars 10. Optionally, the copper bar 10 is close to the housing of the electrical device, and the distance between the copper bar and the housing of the electrical device may be less than a preset distance.

[0039] The plurality of copper bars 10 are arranged at intervals from each other. The number of the copper bars 10 can be 2, 3, 4, etc., and can be arranged as required. The structures of the plurality of copper bars 10 can be substantially the same or different, and there is no limitation.

[0040] Optionally, the plurality of copper bars 10 are spaced apart along the first direction X. Alternatively, the plurality of copper bars 10 may be spaced apart along the second direction Y, the third direction Z, or any other feasible direction, which are not limited.

[0041] Taking multiple copper bars 10 arranged at intervals along the first direction X as an example, the first direction X is roughly the width direction of each copper bar 10, and of course, it can also be the thickness direction, length direction, etc. of each copper bar 10, without limitation. Optionally, the first direction X can also be the width direction of some copper bars 10, the thickness direction, length direction, etc. of other copper bars 10, without limitation.

[0042] In the following text, multiple copper bars 10 are arranged at intervals along the first direction X, the first direction X is the width direction of the multiple copper bars 10, and the shapes of the multiple copper bars 10 are substantially the same. It should be understood that the first direction X can also be different directions of each copper bar 10, and the structures of each copper bar 10 can also be different, without limitation.

[0043] The length direction of the plurality of copper bars 10 is approximately the second direction Y, and the thickness direction is approximately the third direction Z. The length direction of the main part of each copper bar 10 is approximately the second direction Y, and the thickness direction is approximately the third direction Z. The length direction and thickness direction of the remaining part of each copper bar 10 may also be other directions without limitation.

[0044] The specific shape and structure of the copper bar fixing structure 20 are not limited. The copper bar fixing structure 20 is an insulating component, that is, its material is an insulating material, specifically plastic material, bakelite material, etc., which has good structural strength and insulation performance.

[0045] Optionally, at least a portion of each copper busbar 10 is covered by the fixing section 21 , so that the multiple copper busbars 10 are connected and fixed to the copper busbar fixing structure 20 , thereby forming a whole by connecting and fixing the multiple copper busbars 10 through the copper busbar fixing structure 20 .

[0046] The electrical device usually includes a shell and components in the shell. The shell is usually made of metal with high structural strength, such as aluminum alloy, stainless steel and the like, that is, the shell is a conductive component. The copper bar 10 is arranged in the shell. When the distance between the copper bar 10 and the shell is too close, that is, when the distance between the copper bar 10 and the shell of the electrical device is less than the preset distance, if the copper bar 10 is not insulated, a high-voltage arc may be generated between the copper bar 10 and the shell, thereby causing electrical abnormality, resulting in electrical conduction between the copper bar 10 and the shell, and thus causing the shell to be charged. It should be understood that the preset distance is the farthest distance between the copper bar 10 and the shell to generate a high-voltage arc, and its specific value can be set as needed, and the embodiment of the utility model is not limited. The charged shell may cause damage to the components in the shell, resulting in electrical abnormality, and may also cause people to be injured by electric shock when they touch the shell, so insulation protection is required. In the embodiment of the utility model, the isolation section 22 covers at least one copper busbar 10 close to the shell of the electrical device. Further, the isolation section 22 can cover at least one copper busbar 10 whose distance from the shell of the electrical device is less than a preset distance, so that the copper busbar 10 whose distance from the shell of the electrical device is less than the preset distance is separated from the shell by the isolation section 22, thereby avoiding the generation of high-voltage arcing between the copper busbar 10 and the shell, thereby causing electrical abnormalities, and meeting the electrical insulation performance requirements.

[0047] Since the copper bars 10 are spaced apart and the copper bar fixing structure 20 is insulated, the insulation performance between the copper bars 10 can be ensured, and electrical abnormalities such as short circuits will not occur. The two ends of the copper bar 10 in the length direction generally do not need to be covered with the copper bar fixing structure 20, and the two ends can be used to connect with the electrical components to be connected (not shown), which can be battery cells (not shown), connectors (not shown), power distribution interfaces (not shown), power interfaces (not shown), etc., without limitation.

[0048] The copper bar fixing structure 20 provided in the embodiment of the utility model connects a plurality of copper bars 10 spaced apart from each other by setting a fixing section, so that the plurality of copper bars 10 are relatively fixed, and the plurality of copper bars 10 are connected to form a whole through the copper bar fixing structure 20, and the copper bars 10 are insulated from each other, so that the plurality of copper bars 10 constitute a material, which reduces the amount of materials and improves the convenience of operation compared to moving the plurality of copper bars 10 one by one for installation, and the isolation section 22 covers at least one copper bar 10 close to the shell of the electrical device, so as to ensure the electrical insulation performance and avoid electrical abnormalities.

[0049] In one embodiment, reference Figure 1, multiple copper bars 10 are arranged at intervals along the first direction X, and the fixed section 21 extends along the first direction X and connects the multiple copper bars 10. Among them, the main part of the fixed section 21 extends along the first direction X, and a part of it can also extend along the second direction Y or the third direction Z without limitation. Optionally, the size of the fixed section 21 in the third direction Z is larger than the size of the copper bar 10 in the third direction Z, so that the fixed section 21 can cover the copper bar 10. The fixed section 21 can be one or multiple sections arranged at intervals along the second direction Y, without limitation. The fixed section 21 is provided to connect multiple copper bars 10 to form a whole, so that the multiple copper bars 10 form a material.

[0050] Optionally, the fixed section 21 includes a plurality of covering portions 211 and a series connection portion 212 , the plurality of covering portions 211 correspondingly cover a plurality of copper bars 10 , the series connection portion 212 connects two adjacent covering portions 211 , and the series connection portion 212 is located between two adjacent copper bars 10 .

[0051] According to the number of copper bars 10, a corresponding number of covering parts 211 and serial connection parts 212 may be provided. For example, when there are two copper bars 10, there are two covering parts 211 and one serial connection part 212; when there are three copper bars 10, there are three covering parts 211 and two serial connection parts 212; and so on, the number of covering parts 211 is the same as the number of copper bars 10, and the number of serial connection parts 212 is one less than the covering parts 211. The size of the covering part 211 in the third direction Z is larger than the size of the copper bar 10 in the third direction Z, so that the covering part 211 can cover the copper bar 10. There is no requirement for the size of the serial connection part 212 in the third direction Z, as long as the two adjacent covering parts 211 can be stably connected and sufficient structural strength can be maintained. Exemplarily, the size of the serial connection portion 212 in the third direction Z is equal to the size of the covering portion 211 in the third direction Z, and the two surfaces of the serial connection portion 212 and the covering portion 211 in the third direction Z are flush, such as Figure 1 As shown, in this way, the fixing section 21 roughly forms a shape structure and maintains a consistent shape and structure in the first direction X, with low manufacturing difficulty and high structural reliability.

[0052] Optional, reference Figure 1 , the orthographic projections of the plurality of copper bars 10 in the first direction X may overlap, that is, the plurality of copper bars 10 are kept flush at various positions in the third direction Z. In this way, the fixing section 21 may be in the shape of a straight plate extending along the first direction X.

[0053] Optionally, the orthographic projections of some of the multiple copper bars 10 in the first direction X overlap, but the orthographic projections of at least one copper bar 10 in the first direction X are staggered with the orthographic projections of other copper bars 10 in the first direction X. This is to consider that different copper bars 10 need to avoid some structures to avoid interference when connecting electrical components, and to ensure electrical insulation and other requirements, so that adaptive arrangement can be performed. In this case, the entire fixed section 21 extends roughly along the first direction X, but some areas will extend toward the second direction Y or bend in the second direction Y to ensure that all copper bars 10 are connected to form a whole.

[0054] In one embodiment, reference Figures 1 to 3 The outermost copper bar 10 in the first direction X among the multiple copper bars 10 is the first copper bar 10', and the first copper bar 10' is suitable for being close to the housing (not shown) of the electrical device; the isolation segment 22 is coated on the first copper bar 10', and the isolation segment 22 is connected to the fixed segment 21.

[0055] Among the plurality of copper bars 10, there is one copper bar 10 on the outermost side in the first direction X. Figure 2 As shown, the copper bar 10 on the far right in the first direction X is closest to the housing of the electrical device after being installed to the electrical device, and this copper bar 10 is defined as the first copper bar 10'. The distance between the first copper bar 10' and the housing of the electrical device may be less than the preset distance, and the copper bar 10 on the far left in the first direction X has a sufficiently large distance from the housing of the electrical device after being installed to the electrical device, so no special requirements are made for this copper bar 10.

[0056] For the first copper bar 10', since it is closest to the housing of the electrical device, and the housing is usually made of conductive materials such as aluminum alloy and alloy steel, the distance between the first copper bar 10' and the housing is very close, which may be less than the preset distance. To ensure the electrical insulation requirements, the first copper bar 10' needs to be designed for certain insulation isolation. Specifically, in this embodiment, the isolation section 22 of the copper bar fixing structure 20 is provided to cover the first copper bar 10', so as to meet the insulation isolation design requirements of the first copper bar 10'.

[0057] The isolation section 22 covers a local area of ​​the first copper bar 10', and can be directly connected to the covering portion 211 covered on the first copper bar 10', or can be indirectly connected to the covering portion 211 or the serial connection portion 212, without limitation. The isolation section 22 is connected to the fixing section 21, so that the copper bar fixing structure 20 forms an integral body, which can strengthen the connection and fixing effect of multiple copper bars 10 (including the first copper bar 10'), so that the multiple copper bars 10 have strong structural strength and stability as a material, and avoid falling apart during transportation and movement.

[0058] Optional, reference Figure 1The isolation segment 22 is spaced apart from the covering portion 211 covering the first copper bar 10'. In this embodiment, the isolation segment 22 is indirectly connected to the fixing segment 21, and the indirect connection method is not limited. In this way, only the isolation segment 22 needs to be partially arranged to meet the electrical insulation performance requirements between the first copper bar 10' and the housing, saving materials.

[0059] Optionally, the copper bar fixing structure 20 further includes a connecting section 23 , which is located between the first copper bar 10 ′ and the adjacent copper bar 10 , and is connected to the series connection portion 212 and the isolation section 22 .

[0060] In this embodiment, the isolation section 22 is connected to the serial connection portion 212 via the connection section 23, so that the fixed section 21 and the isolation section 22 are connected to form a whole through the connection section 23, thereby ensuring the connection stability. The connection section 23 is located between two copper bars 10, and can play an insulating and isolating role between two adjacent copper bars 10, thereby preventing abnormalities such as electrical breakdown from occurring when the distance between two adjacent copper bars 10 is too close.

[0061] In one embodiment, reference Figures 1 to 3 The copper busbar fixing structure 20 further includes a positioning section 24 , which is connected to the fixing section 21 and protrudes from the fixing section 21 . The positioning section 24 is suitable for positioning the copper busbar assembly 100 .

[0062] Specifically, the positioning section 24 is connected to the serial connection portion 212, and the positioning section 24 can protrude from the fixed section 21 in the second direction Y and / or the third direction Z so as to abut against the positioning structure on the electrical device to position the copper busbar assembly 100 during installation, thereby achieving rapid positioning and installation of the copper busbar assembly 100.

[0063] Optionally, the positioning section 24 is located between two adjacent copper bars 10 and connected to the serial connection portion 212 .

[0064] Alternatively, the positioning section 24 may be located at any other position except between two adjacent copper bars 10 , and may be connected to the covering portion 211 , the isolation section 22 , the connection section 23 , etc., without limitation.

[0065] There can be one or more positioning segments 24. When there is one positioning segment 24, it can protrude from the copper busbar 10 in the second direction Y or the third direction Z. When there are multiple positioning segments 24, all of them can protrude from the copper busbar 10 in the second direction Y or the third direction Z, or some positioning segments 24 can protrude from the copper busbar 10 in the second direction Y and other positioning segments 24 can protrude from the copper busbar 10 in the third direction Z, without limitation.

[0066] refer to Figures 1 to 3The embodiment of the utility model further provides a copper busbar assembly 100, comprising a plurality of copper busbars 10 and a copper busbar fixing structure 20 in any of the aforementioned embodiments.

[0067] The plurality of copper bars 10 are spaced apart from each other. The copper bar fixing structure 20 is an insulating component and includes a fixing section 21 and an isolation section 22. The fixing section 21 connects the plurality of copper bars 10. The isolation section 22 covers at least one copper bar 10 among the plurality of copper bars 10 that is close to the housing of the electrical device.

[0068] Regarding the copper busbar 10 and the copper busbar fixing structure 20 , reference may be made to the above description and no limitation is given here.

[0069] The copper busbar assembly 100 provided in the embodiment of the utility model is connected with a plurality of copper busbars 10 spaced apart from each other by setting a fixed section, so that the plurality of copper busbars 10 are relatively fixed, and the plurality of copper busbars 10 are connected to form a whole through a copper busbar fixing structure 20, and the copper busbars 10 are insulated from each other, so that the copper busbar assembly 100 constitutes a material, and the plurality of copper busbars 10 are moved one by one for installation, which reduces the amount of materials and improves the convenience of operation. The isolation section 22 covers at least one copper busbar 10 close to the shell of the electrical device, which can ensure the electrical insulation performance and avoid electrical abnormalities.

[0070] Optionally, the copper bar fixing structure 20 and the plurality of copper bars 10 are formed into one body by injection molding. In the present embodiment, the copper bar fixing structure 20 is a plastic material, and the copper bar assembly 100 is made by an injection molding process. Specifically, the plurality of copper bars 10 can be first placed in a mold cavity of a preset mold (not shown) and fixed, and then molten plastic liquid is injected into the mold cavity, and the plastic liquid fills the mold cavity and gradually cools and solidifies. After the plastic liquid solidifies, demolding is performed, and the solidified plastic liquid forms the copper bar fixing structure 20, thereby obtaining the copper bar assembly 100 of the present utility model embodiment.

[0071] The method of forming an integral body by injection molding has a simple process and high connection reliability, and no other additional connection components are required.

[0072] Combined with the above description, the plurality of copper bars 10 can be arranged arbitrarily, and the fixed section 21 can be set adaptively. Optionally, the plurality of copper bars 10 are arranged at intervals along the first direction X, and the fixed section 21 extends along the first direction and connects the plurality of copper bars 10. This example is used for detailed description below, and it should be understood that other methods are also feasible.

[0073] In one embodiment, reference Figure 1The copper busbar 10 includes a main body section 11, a first mounting section 12 and a second mounting section 13. The main body section 11 extends along the second direction Y, the first mounting section 12 is connected to one end of the main body section 11 in the second direction Y, and the second mounting section 13 is connected to the other end of the main body section 11 in the second direction Y. The first mounting section 12 and the second mounting section 13 both extend along the third direction Z, and the first mounting section 12 and the second mounting section 13 protrude from opposite sides of the main body section 11, respectively. The copper busbar fixing structure 20 covers at least a portion of the main body section 11.

[0074] The main body section 11 extends along the second direction Y as a whole, and a local area thereof may extend along other directions other than the second direction Y, without limitation. The copper bar fixing structure 20 covers at least part of the main body section 11, and the fixing section 21 covers at least part of the main body section 11. For the first copper bar 10', the isolation section 22 also covers at least part of the main body section 11, and the connection section 23 is located between the main body sections 11 of the first copper bar 10' and the adjacent copper bar 10.

[0075] The first mounting section 12 and the second mounting section 13 may be provided with holes, grooves, notches, protrusions and other structures for connecting with electrical components, and the specific structures are not limited, and they are respectively used to connect with different electrical components. The first mounting section 12 and the second mounting section 13 need to be exposed and cannot be covered with the copper busbar fixing structure 20 to achieve electrical connection.

[0076] The copper busbar 10 is an integrated structure, that is, the main section 11, the first mounting section 12 and the second mounting section 13 are an integrated structure. The copper busbar 10 can be made by plate stamping and bending processes, die-casting processes and other processes. The first mounting section 12 and the main section 11 can have a smooth transition, and the second mounting section 13 and the main section 11 can also have a smooth transition to avoid stress concentration and improve structural strength and stability.

[0077] In one embodiment, reference Figure 1 The main body section 11 includes a first section 111, a second section 112 and a third section 113 which are sequentially connected along the second direction Y. The second section 112 is curved and protrudes from the first section 111 and the third section 113 in the third direction Z.

[0078] Optionally, the length directions of the first segment 111 and the third segment 113 may both be the second direction Y, that is, the orthographic projections of the first segment 111 and the third segment 113 in the second direction Y may substantially coincide. Figure 1, the first section 111 is a straight plate with its length direction being the second direction Y, the third section 113 is a straight plate with its length direction being the second direction Y as a whole, but the orthographic projection of a part connected to the second section 112 in the second direction Y coincides with the first section 111, and the orthographic projection of another part away from the second section 112 in the second direction Y coincides with the first section 111 in part and intersects in part, that is, the third section 113 is bent. Of course, the shapes and structures of the first section 111 and the third section 113 may also be other options, without limitation.

[0079] Optionally, the orthographic projection of the second section 112 in the first direction X is substantially semicircular, and the second section 112 may be smoothly connected to the first section 111 and the third section 113 to avoid stress concentration.

[0080] The second section 112 is provided with a curved structure. When the copper busbar 10 is installed, the first section 111 and the third section 113 can be pulled or squeezed in the second direction Y, so that the second section 112 is deformed, thereby achieving accurate installation of the copper busbar 10 and the electrical components. That is, the curved shape of the second section 112 can absorb the installation tolerance through deformation, thereby reducing the dimensional accuracy requirements and reducing the manufacturing cost.

[0081] The fixed section 21 of the copper bar fixing structure 20 can be connected to the first section 111, and the third section 113 of the first copper bar 10' can at least partially cover the isolation section 22. For the first copper bar 10', since a connecting section 23 is provided to connect the fixed section 21 and the isolation section 22, the second section 112 may not be provided, and the first section 111 and the third section 113 may be directly connected. Of course, the copper bar fixing structure 20 has a certain deformation ability, so the first copper bar 10' may also be provided with a second section 112. When the first copper bar 10' is deformed along the second direction Y, the second section 112 and the copper bar fixing structure 20 may both be deformed to a certain extent to meet the installation accuracy requirements.

[0082] Optional, reference Figure 1 The copper busbar 10 further includes a rivet nut 14, which is an integral structure with the first mounting section 12. The rivet nut 14 and the first mounting section 12 can be made by an integral molding process such as machining and die casting, without limitation. The first mounting section 12 has a rivet nut 14, which can be easily installed and fixed with the electrical components.

[0083] In one embodiment, reference Figure 1 The copper busbar 10 further includes a limiting section 15 , which is connected to an end of the second mounting section 13 away from the main section 11 , and the limiting section 15 and the second mounting section 13 have an included angle.

[0084] The limiting section 15 can extend roughly along the second direction Y and be located on the side of the second mounting section 13 facing away from the main section 11. The limiting section 15 and the second mounting section 13 can be connected by a smooth transition to avoid stress concentration. The angle between the limiting section 15 and the second mounting section 13 can be roughly 90°, and of course, it can also be other angles such as 60°-120°, without limitation. When the second mounting section 13 is installed with the electrical component, the limiting section 15 can abut against other limiting structures in the electrical component or electrical device to limit the copper busbar 10, ensure the accurate position of the copper busbar 10 during installation, and limit the copper busbar 10 to avoid problems such as rotation and shaking of the copper busbar 10.

[0085] In summary, by setting up the copper busbar assembly 100 of the embodiment of the utility model, both the installation flexibility is achieved, and the copper busbar assembly 100 can be managed and transported as a whole as a material, and the installation accuracy is achieved. Through the positioning section 24 of the copper busbar fixing structure 20 and the limiting section 15 of the copper busbar 10, it can be quickly positioned and the stability of the structure can be guaranteed after installation.

The electrical device can be any feasible device such as a vehicle-mounted power supply, a battery pack, etc., without limitation. The electrical device includes a housing and electrical components in the housing, etc. The electrical components and the copper busbar assembly 100 are installed in the housing, and the copper busbar assembly 100 is used to connect the electrical components of the electrical device.
