Abstract
Description
Technical Field
[0001] This utility model relates to the field of electrical connection components, specifically a novel aluminum busbar with a data acquisition structure. Background Technology
[0002] Currently, common aluminum busbar connection methods for achieving low-voltage data acquisition mainly involve bolting, soldering, and laser welding. Taking laser welding as an example, a nickel plate needs to be added between the aluminum busbar and the acquisition line as a transitional connection component. The nickel plate is then fixed to both the aluminum busbar and the acquisition line using laser welding (as shown in the attached image). Figure 3 (As shown). However, this structure has the following significant drawbacks: 1. Laser welding requires precise positioning, resulting in high equipment debugging costs and long welding times per operation, making it difficult to meet the needs of large-scale production; 2. Additional processes such as nickel sheet installation and welding are required, increasing labor costs; 3. Collecting nickel sheets as independent components requires additional procurement and inventory management, increasing overall costs; 4. The welding interface may crack or oxidize due to thermal stress, affecting long-term conductivity stability. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a novel aluminum busbar with a data acquisition structure, which solves the technical problem of high cost in the existing connection structure between the aluminum busbar and the data acquisition line.
[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel aluminum busbar with a data acquisition structure, comprising an aluminum busbar body, wherein the aluminum busbar body is provided with an integrally formed connecting part, and a data acquisition line is pressed onto the connecting part;
[0005] The connecting part includes a connecting arm that is connected to the aluminum busbar body. The connecting arm has a convex groove structure formed by stamping, and one end of the acquisition line is pressed into the convex groove structure.
[0006] Preferably, the inner surface of the convex groove structure is provided with anti-slip texture, which is one of the following: grid, stripe, or serrated.
[0007] Preferably, the convex groove structure includes a fixed edge and a folded edge. The fixed edge is connected to the connecting arm, and the folded edge is formed by bending the two ends of the fixed edge inward. The fixed edge and the folded edge together form a groove for fixing one end of the acquisition line.
[0008] Preferably, the distance between the two folded edges is less than the thickness of one end of the acquisition line, so as to achieve interference fit of the acquisition line.
[0009] Preferably, the inner surface of the convex groove structure is provided with a conductive coating.
[0010] Preferably, the conductive coating is either a silver plating or a nickel plating.
[0011] By employing the above technical solution, this utility model provides a novel aluminum busbar with a data collection structure, which has at least the following beneficial effects:
[0012] 1. This new type of aluminum busbar with a collection structure forms a convex groove structure by directly stamping it on the main body of the aluminum busbar, replacing the traditional laser welding process and the collection nickel sheet. This eliminates the cost of nickel sheet procurement, investment in laser welding equipment, and manual welding procedures, resulting in a significant reduction in material and process costs.
[0013] 2. This new type of aluminum busbar with a data acquisition structure uses a convex groove structure to directly clamp the data acquisition line through mechanical pressing, eliminating the need for complex positioning and welding processes. This simplifies the operation steps and avoids problems such as thermal stress cracks and oxidation that may occur during laser welding, improving connection efficiency while enhancing conductivity stability and structural reliability.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] In the fields of batteries and conductive connections, aluminum busbars are widely used as conductive components, and their connection method with the acquisition line 2 directly affects conductivity, production cost, and process efficiency. (See the attached diagram in the manual.) Figure 6 As shown, the connection structure is made by welding nickel sheets. This method increases the cost of nickel sheets, raising the overall production cost. It also requires high-quality welding and sophisticated equipment, further increasing production costs.
[0025] Example 1
[0026] Due to the high cost and technical limitations of existing technologies, please refer to... Figures 1-3 This embodiment provides a novel aluminum busbar with a data acquisition structure. By directly stamping a convex groove structure 32 onto the main body 1 of the aluminum busbar, a traditional laser welding process and data acquisition nickel sheet are replaced. This eliminates the cost of nickel sheet procurement, investment in laser welding equipment, and manual welding procedures, significantly reducing material and process costs. The main body 1 of the aluminum busbar has an integrally formed connecting part 3, on which a data acquisition line 2 is pressed. The data acquisition line 2 is directly pressed onto the integral connecting part 3, eliminating the need for data acquisition nickel sheet and laser welding process. This simplifies the structure and reduces material and labor costs. Furthermore, the pressing method improves assembly efficiency and is suitable for large-scale production.
[0027] The existing connection between the aluminum busbar and data acquisition line 2 requires laser welding. However, laser welding requires precise positioning and is equipment-dependent, resulting in low welding efficiency and high positioning difficulty. To address this issue, please refer to... Figure 2The connecting part 3 includes a connecting arm 31 connected to the aluminum busbar body 1. The connecting arm 31 is provided with a convex groove structure 32 formed by stamping. One end of the acquisition line 2 is pressed into the convex groove structure 32. Further, the convex groove structure 32 includes a fixed edge 321 and a folded edge 322. The fixed edge 321 is connected to the connecting arm 31, and the folded edge 322 is formed by bending the two ends of the fixed edge 321 inward. The fixed edge 321 and the folded edge 322 together form a slot for fixing one end of the acquisition line 2. The stamping process is used. This method replaces laser welding, eliminates the need for complex equipment debugging, simplifies the process, and increases production efficiency. The convex groove structure 32 mechanically presses and fixes the acquisition line 2, avoiding the impact of welding thermal stress on material properties and improving connection stability. During production, one end of the acquisition line 2 is placed on the fixed edge 321, and then the folded edge 322 is bent using a stamping device. After bending, the convex groove structure 32 is formed. The folded edge 322 presses and fixes the acquisition line 2, thereby achieving the connection between the acquisition line 2 and the aluminum busbar.
[0028] Traditional welding or crimping methods may cause problems such as loosening and poor contact of the acquisition line 2 due to the smooth contact surface, which affects the reliability of conductivity. To address this issue, the inner surface of the convex groove structure 32 is provided with anti-slip texture, specifically, the anti-slip texture is grid-shaped. The anti-slip texture increases the friction of the contact surface, preventing the acquisition line 2 from sliding or falling off after crimping, improving the mechanical connection strength and conductivity stability. Moreover, the grid-shaped design can provide friction in multiple directions, which can disperse the pressure on the contact surface, reduce local wear, and extend the service life of the anti-slip layer.
[0029] Furthermore, the distance between the two folded edges 322 is less than the thickness of one end of the acquisition line 2, so as to achieve interference fit of the acquisition line 2, and the clamping force generated by the interference fit can further prevent the acquisition line 2 from loosening and enhance the connection reliability.
[0030] Direct contact between the aluminum busbar and the acquisition line 2 may lead to oxidation due to metal electrochemical corrosion, affecting long-term conductivity. To address this issue, a conductive coating 323 is provided on the inner surface of the convex groove structure 32. Specifically, the conductive coating 323 is a silver plating layer. As an anti-oxidation conductive layer, the silver plating layer can isolate the direct contact between the aluminum and the acquisition line 2, inhibit electrochemical corrosion and oxidation, extend service life, and has excellent conductivity, strong resistance to oxidation and sulfur at room temperature, and good solderability.
[0031] Example 2
[0032] Basically the same as in Example 1, see reference. Figure 4The difference lies in the fact that the anti-slip texture is striped, and the anti-oxidation conductive layer 323 is a nickel plating layer. The striped design can provide stronger friction in the front and back directions, and the striped structure is simpler than the grid. The mold cost is lower and the process is less difficult during production. The nickel plating layer has a good cost performance and comprehensive mechanical properties, and has good wear resistance and corrosion resistance.
[0033] Example 3
[0034] Basically the same as in Example 1, see reference. Figure 5 The difference lies in the fact that the anti-slip texture is serrated; the sharp edges of the serrations can be embedded in the tiny gaps of the contact surface to provide instantaneous high friction, so as to prevent the collection line 2 from falling off when pulled.
