Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a wiring harness with terminals and an aluminum busbar connection structure. Background Art

[0002] In the context of high safety, high reliability and low cost requirements for new energy vehicle battery packs, more reliable processes and cost reduction technology support are urgently needed. In the current aluminum busbar connection components, the connection is only laser welding. Once a false weld or poor welding occurs, there will be functional risks, affecting the use of the product.

[0003] Therefore, it is urgent to develop a more reliable connection structure between the wiring harness and the aluminum busbar with terminals. Utility Model Content

[0004] The present invention aims to solve one of the above technical problems at least to a certain extent.

[0005] To this end, the purpose of the present invention is to provide a wiring harness with terminals and an aluminum bar connection structure, which makes the connection more reliable.

[0006] To achieve the above-mentioned purpose, an embodiment of the present application discloses a wiring harness with a terminal and an aluminum busbar connection structure, comprising a wiring harness (1), a terminal (2), and an aluminum busbar (3); wherein one end of the terminal (2) is connected to the wiring harness (1), and the other end is provided with a boss (21); the aluminum busbar (3) is provided with a connection hole (31); and the boss (21) is connected to the connection hole (31).

[0007] In addition, the wiring harness and aluminum bar connection structure with terminals according to the above technical solution of the present application may also have the following additional technical features:

[0008] Optionally, the boss (21) is a bent boss.

[0009] Optionally, the boss (21) is a bent boss that is bent into a “concave” shape.

[0010] Optionally, the connecting hole (31) is a rectangular hole.

[0011] The beneficial effects of the present application are: perfect contact between the terminal and the aluminum busbar can be achieved, dual fixation by crimping and welding can be achieved, the risk of non-conduction can be avoided, and the reliability of the product can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 It is a structural schematic diagram of a wiring harness with terminals and an aluminum busbar connection structure provided by an embodiment of the present application.

[0013] Figure 2 It is a structural schematic diagram of a wiring harness with terminals and an aluminum busbar connection structure provided in another embodiment of the present application.

[0016] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or components / elements with the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0017] The following describes a method for forming a wiring harness with terminals and an aluminum busbar connection structure according to an embodiment of the present application in conjunction with the accompanying drawings.

[0018] Figure 1 is a schematic structural diagram of a wiring harness with terminals and an aluminum bar connection structure provided by an embodiment of the present application. Figure 2 FIG. 1 is a schematic diagram of a structure of a wiring harness with terminals and an aluminum bar connection structure provided by another embodiment of the present application. Figure 1-2 As shown: the wiring harness with terminal and aluminum bus connection structure includes a wiring harness 1, a terminal 2, and an aluminum bus 3; wherein one end of the terminal 2 is connected to the wiring harness 1, and the other end is provided with a boss 21; the aluminum bus 3 is provided with a connecting hole 31; the boss 21 is connected to the connecting hole 31.

[0019] Specifically, the conventional terminal is a flat terminal, and the solution of the present application is to process a boss 21 on the terminal 2, insert the boss 21 into the connection hole 31 in the aluminum bar 3, and then fix it by laser welding or ultrasonic welding. At the same time, from the shape of the boss 21, it can be seen that the area of ​​contact between the boss 21 and the aluminum bar is slightly larger than that of the conventional terminal with a flat end face, which can also improve the reliability of the connection.

[0020] According to the wiring harness with terminal and aluminum bar connection structure of the present application, the boss is inserted into the connection hole so that the terminal is fully in contact with the aluminum bar, and then welding is performed, and double fixation is performed, so that the reliability of the product is further guaranteed.

[0021] According to an embodiment of the present application, the boss 21 is a bent boss.

[0022] According to an embodiment of the present application, the boss 21 is a bent boss bent into a “concave” shape.

[0023] Specifically, the terminal end can be processed into a bent boss by stamping or other cold working methods, especially Figure 1 The "concave"-shaped bending boss shown is easy to process and has low cost.

[0024] According to an embodiment of the present application, the connection hole 31 is a rectangular hole.

[0025] Specifically, the rectangular hole has good compatibility with the “concave”-shaped bent boss, which can maximize the contact area between the connecting hole 31 and the boss 21 .

[0026] The above embodiments are preferred implementation schemes of the present application. In addition, the present application may also be implemented in other ways. Any obvious replacement without departing from the concept of the present application is within the protection scope of the present application.
