[0071] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0072] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0073] Batteries are devices that can convert chemical energy into electrical energy. They have the characteristics of simple structure, easy portability, and simple and easy charging and discharging operations. The installation and use of batteries are inseparable from copper bars or aluminum bars. In related technologies, copper bars and aluminum bars are mostly made of extrusion, heat shrink tubing or powder spraying as the insulation layer of copper bars and aluminum bars. In this case, the copper bars or aluminum bars cannot be fixed. If the copper bars or aluminum bars are fixed to the surrounding objects with cable ties, the insulation layer of the copper bars or aluminum bars will be worn, resulting in the failure of insulation protection.

[0074] In order to solve the above problems, the embodiments of the present application provide an insulating protection component, a battery module, a battery pack and an electrical device, wherein the insulating protection component can be used as an insulating layer of an electrical connector, covering special areas such as the straight and corner areas of the electrical connector, and a card connector is integrated on the insulating protection component, and the card connector is used to connect with surrounding objects. This can solve the problem in the related art that copper bars and aluminum bars cannot be fixed, and using cable ties to fix copper bars and aluminum bars to surrounding objects will cause the insulating layer of the copper bars or aluminum bars to wear, resulting in the failure of insulation protection.

[0075] The insulation protection assembly, battery module, battery pack and electrical device provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings and specific embodiments.

[0076] The battery module disclosed in the embodiments of the present application can be used for electrical devices that use batteries as power sources or various energy storage systems that use batteries as energy storage elements. Electrical devices can be, but are not limited to, mobile phones, tablets, laptops, electric toys, electric tools, battery cars, electric cars, ships, spacecraft, etc. Among them, electric toys can include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc., and spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0077] Figure 1 This is a schematic diagram of an insulation protection assembly 100 provided in an embodiment of the present application applied to an electrical connector 210, see Figure 1As shown, the insulation protection component 100 provided in the embodiment of the present application can be applied to the electrical connector 210. The electrical connector 210 can be a metal electrical connector such as a copper bar or an aluminum bar. The insulation protection component 100 is made of an insulating material, such as plastic, resin, polymer material, etc. In some embodiments of the present application, the insulation protection component 100 can be made by an injection molding process as a preform made for a certain model or certain models of electrical connectors 210, and the electrical connector 210 is insulated and protected.

[0078] The insulating protection assembly 100 includes: a straight piece 110 and a curved piece 120. Both the straight piece 110 and the curved piece 120 have a receiving cavity through which the power supply connector 210 passes. The receiving cavity of the straight piece 110 is adapted or interference-fitted with the straight area of ​​the electrical connector 210, and the receiving cavity of the curved piece 120 is at least partially adapted or interference-fitted with the curved area of ​​the electrical connector 210. "The receiving cavity of the curved piece 120 is at least partially adapted or interference-fitted with the curved area of ​​the electrical connector 210" means that the receiving cavity of the curved piece 120 needs to at least be adapted or interference-fitted with the curved area of ​​the electrical connector 210, and the curved piece 120 may cover part of or not cover the straight area extending from the curved area.

[0079] The purpose of “the accommodating cavity of the straight member 110 is adapted or interference fit with the straight area of ​​the electrical connector 210, and the accommodating cavity of the curved member 120 is adapted or interference fit with the curved area of ​​the electrical connector 210” is to fix the straight member 110 and the curved member 120 on the electrical connector 210. For example, when the working environment is free of vibration or the vibration is not large, the accommodating cavity of the straight member 110 is adapted to the straight area of ​​the electrical connector 210, and the accommodating cavity of the curved member 120 is adapted to the curved area of ​​the electrical connector 210, so that the straight member 110 and the curved member 120 can be fixed on the electrical connector 210. When the working environment has large vibration, the accommodating cavity of the straight member 110 and the straight area of ​​the electrical connector 210 can be interference fit, and the accommodating cavity of the curved member 120 and the curved area of ​​the electrical connector 210 can be interference fit, so that the straight member 110 and the curved member 120 can be fixed on the electrical connector 210.

[0080] It should be noted that in the embodiment of the present application, the number of the straight member 110 and the curved member 120 can be one or more, and the number of the straight member 110 and the curved member 120 should be set according to the points that the electrical connector 210 needs to protect. Figure 1 If the straight area to be protected by the electrical connector 210 has two sections, two straight members 110 can be provided, and if the curved area to be protected by the electrical connector 210 has one section, one curved member 120 can be provided. Here, the embodiment of the present application does not limit the number of straight members 110 and curved members 120.

[0081] In the embodiment of the present application, a clamping joint 130 is provided on the straight member 110 and / or the curved member 120, and the clamping joint 130 is used to clamp with the interface of the surrounding object. Here, "a clamping joint 130 is provided on the straight member 110 and / or the curved member 120" means that the clamping joint 130 can be provided on the straight member 110 or the curved member 120, or the clamping joint 130 can be provided on both the straight member 110 and the curved member 120. For example, Figure 1 As shown, the clamping joint 130 is disposed on one of the two straight pieces 110 .

[0082] The clamping connector 130 can be assembled on the straight part 110 and / or the curved part 120 as a separate part through a series of conventional connection methods such as bonding and clamping, or it can be integrally formed with the straight part 110 and / or the curved part 120 and integrated on the straight part 110 and / or the curved part 120.

[0083] It is understandable that the insulation protection assembly 100 provided in the embodiment of the present application, through the straight piece 110 and the curved piece 120, performs insulation protection on the straight area and the curved area of ​​the electrical connector 210 that need insulation protection, which can replace the insulation layer formed by extrusion, heat shrink tube or powder spraying in the related art. Of course, the electrical connector 210 can also have its own insulation layer, and the insulation protection assembly 100 can be used as a second insulation protection to further protect the electrical connector 210. And a clamping joint 130 is provided on the straight piece 110 and / or the curved piece 120, and the clamping joint 130 can be clamped with the surrounding objects. By the fixation of the straight piece 110 and the curved piece 120 with the electrical connector 210, the electrical connector 210 can be fixed. In addition, it can also solve the problem in the related art that the copper bar and the aluminum bar are fixed to the surrounding objects by using cable ties, resulting in the wear of the insulation layer of the copper bar or the aluminum bar, causing the insulation protection to fail. In addition, by clamping the clamping connector 130 , the electrical connector 210 can be easily fixed, thereby reducing the assembly workload.

[0084] refer to Figure 1 As shown, in some embodiments of the present application, the clamping joint 130 is a flexible member, and the clamping joint 130 is umbrella-shaped. The flexible umbrella-shaped clamping joint 130 is conducive to clamping with surrounding objects, and the insulation protection component 100 can be fixed by pressing, and the fixing method is convenient and fast. Of course, in other embodiments of the present application, the clamping joint 130 can also be other shapes and materials, as long as the clamping joint 130 can be clamped with surrounding objects.

[0085] Of course, this application is not limited to this, please refer to Figure 1As shown, in some embodiments of the present application, the length of the straight member 110 is equal to the length of the corresponding straight area of ​​the electrical connector 210. On the one hand, the entire straight area corresponding to the electrical connector 210 can be provided with insulation protection. On the other hand, when the straight area is located at two corners of the electrical connector 210, the two corners can clamp the straight member 110, which can further ensure the fixation of the insulation protection assembly 100 on the electrical connector 210, thereby ensuring the fixation of the electrical connector 210 relative to the surrounding objects.

[0086] It should be noted that the flat member 110 can be a whole or multiple parts. Figure 1 As shown, in some embodiments of the present application, the straight member 110 may include a plurality of straight sub-members 111, and the plurality of straight sub-members 111 are connected end to end and spliced ​​to form the straight member 110. It is understandable that dividing the straight member 110 into a plurality of straight sub-members 111 can be applicable to various types of electrical connectors 210. For example, when the length of the straight area at the two corners of a certain electrical connector 210 is 20 cm, 5 straight sub-members 111 with a length of 4 cm can be used, or 4 straight sub-members 111 with a length of 5 cm can be used. When the length of the straight area at the two corners of a certain electrical connector 210 is 16 cm, 4 straight sub-members 111 with a length of 4 cm can be used. The straight sub-members 111 can be prefabricated and can be applicable to various electrical connectors 210. The present application is described by taking the example that the straight member 110 includes a plurality of straight sub-members 111. In some embodiments of the present application, the snap-in connector 130 can be disposed on the straight component 111, which corresponds to the straight area of ​​the electrical connector 210. The snap-in connector 130 is disposed on the straight component 111 to facilitate the snap-in fixation of the snap-in connector 130 and reduce the risk of interference with surrounding objects.

In this way, the insulation protection assembly 100 can achieve single-sided protection of the electrical connector 210. The snap joint 130 can be provided on the first cover 112 and / or the second cover 121.

Here, there is no specific limitation on the integration and connection method of the first cover body 112 and the third cover body 113 , and the second cover body 121 and the fourth cover body 122 .

[0090] Of course, part of the first cover 112 and part of the third cover 113, part of the second cover 121 and part of the fourth cover 122 can also be integrally formed, for example, the first cover 112 and the third cover 113, the second cover 121 and the fourth cover 122 can be integrally injection molded. This can facilitate mass production of the insulation protection assembly 100. The integrally formed first cover 112 and the third cover 113 can be sleeved into the straight area from the end of the electrical connector 210, where the straight area is not a straight area with curved areas at both ends.
