Description

Technical Field

[0001] The utility model belongs to the technical field of copper busbar insulation, and in particular relates to a copper busbar insulation structure. Background Art

[0002] With the rapid development of electric vehicles, energy storage systems and other fields, lithium-ion battery packs are becoming the mainstream choice in these fields as an efficient and reliable energy storage solution. Lithium-ion batteries are a very important energy storage technology and are widely used in electric vehicles, mobile phones, laptops and other fields. With its advantages such as high energy density, long cycle life and low self-discharge rate, it has become the mainstream technology in the current battery field. Lithium-ion battery packs have been widely used in various fields, especially in the field of electric vehicles. At present, there are many batteries in series and parallel in electric vehicles. In order to ensure the safety and maintainability of the battery during use, the battery system adopts a modular design, and different numbers of batteries are connected in series and parallel to form a module. Lithium-ion battery systems usually work under high voltage and high current conditions. Its safety and reliability are one of the key factors to focus on. In the process of lithium-ion battery system composition, it is necessary to connect the batteries in series and parallel through conductors. The conductor parts used to achieve series and parallel connection are called copper busbars.

[0003] At present, the insulation treatment solutions for copper busbars on the market are as follows: 1. Insulation coating Insulation coating is one of the most common insulation treatment methods for copper busbars. A layer of insulating paint or insulating paint film is applied to the surface of the copper busbar to prevent the corrosion of the copper busbar by environmental factors such as air and moisture. Usually, the insulating coating can be made of materials such as epoxy resin, polyurethane, and fluorocarbon spray. 2. Insulation sleeve is another common insulation treatment solution for copper busbars. Insulation sleeve is a tubular insulating material that can wrap the copper busbar in it to form an insulating protective layer. 3. Insulation tape is also a common insulation treatment method for copper busbars. Insulation tape is made of an adhesive with an insulating layer and can be easily attached to the surface of the copper busbar.

[0004] Therefore, a copper busbar insulation structure is needed to solve the problem in the prior art that the copper busbar is easily mechanically damaged and easily corroded. Utility Model Content

[0005] The purpose of the utility model is to provide a copper busbar insulation structure to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a copper busbar insulation structure, comprising a first protective cover, a second protective cover, and a third protective cover, wherein a first clamping mechanism and a second clamping mechanism are respectively arranged on both sides of the first protective cover, and a protective layer is arranged on the outer side of the first protective cover, the second protective cover, and the third protective cover.

[0007] It should be noted that the first clamping mechanism includes a first buckle, which is installed on the surface of the first protective cover and at one end corresponding to the second protective cover;

[0008] The first clamping mechanism also includes a first clamping port, which is opened on the surface of the second protective cover and at an end corresponding to the first protective cover, and the first buckle is clamped with the first clamping port.

[0009] It is further worth noting that the second clamping mechanism includes a second clamping buckle, and the second clamping buckle is installed on the surface of the third protective cover and at an end corresponding to the first protective cover;

[0010] The second clamping mechanism also includes a second clamping opening, which is opened on the surface of the first protective cover and at an end corresponding to the third protective cover, and the second buckle is clamped with the second buckle.

[0011] It should be further explained that the protective layer includes a wear-resistant layer and a high-temperature resistant layer attached sequentially from the outside to the inside.

[0012] As a preferred implementation, the wear-resistant layer mainly improves the wear resistance of the insulating protective sleeve, and the high-temperature resistant layer improves the high-temperature resistance of the insulating sleeve.

[0013] As a preferred implementation, copper bars are provided on both end surfaces of the second protective cover and the third protective cover.

[0014] Compared with the prior art, the copper busbar insulation structure provided by the utility model has at least the following beneficial effects:

[0015] (1) Through the mutual cooperation among the first buckle, the first bayonet, the second buckle and the second bayonet, the first protective cover, the second protective cover and the third protective cover can be quickly installed, thereby improving work efficiency. In addition, through the cooperation among the first protective cover, the second protective cover and the third protective cover, the copper busbar can be protected from mechanical damage. The copper busbar may be damaged by mechanical impact or extrusion during use, and the insulating cover can prevent such damage from occurring.

[0016] (2) The protective layer, wear-resistant layer and high-temperature resistant layer work together to protect the copper busbar from chemical corrosion: the copper busbar may be exposed to various chemicals in the use environment, such as acids, alkalis, salts, etc. The insulating sheath can prevent these substances from corroding the copper busbar.

[0017] (3) By isolating the copper busbar from contact with other metals: The copper busbar may come into contact with other metals, such as aluminum terminal blocks, during use. Copper is prone to corrosion when in contact with other metals, resulting in a reduction in contact area, which in turn affects electrical performance. The insulating sheath can isolate the copper busbar from contact with other metals, thereby ensuring the electrical performance of the copper busbar. BRIEF DESCRIPTION OF THE DRAWINGS
