Description

Technical Field

[0001] The utility model relates to the technical field of battery protection plates, in particular to an anti-breakage battery protection plate electrical contact component. Background Art

[0002] The lithium battery protection board is a charge and discharge protection for the series lithium battery pack. When fully charged, it can ensure that the voltage difference between each single battery is less than the set value, realize the equal charging of each single battery in the battery pack, effectively improve the charging effect under the series charging mode, and protect and extend the battery life. The components and electrical contact components on the existing battery protection board lack protective components, which leads to the surface of the electrical contact components being easily damaged when the battery protection board falls, resulting in the phenomenon of the electrical contact components being broken, thereby reducing the service life of the battery protection board and increasing the maintenance cost of the battery.

[0003] After searching, in the published patent (CN218867253U, a damage-resistant battery protection board electrical contact assembly), the upper protective cover, rubber strip, limit block, mounting bolt, lower protective cover and fixing block and other parts can effectively solve the problem that the components and electrical contact assembly on the existing battery protection board lack protective components, which leads to the surface of the electrical contact assembly being easily damaged when the battery protection board falls, thereby causing the electrical contact assembly to be broken, thereby reducing the service life of the battery protection board and increasing the maintenance cost of the battery; although the electrical contact assembly can be effectively protected, it is installed by multiple bolts, which makes the installation process more cumbersome and inconvenient for subsequent disassembly and maintenance. Therefore, we introduce a new damage-resistant battery protection board electrical contact assembly. Utility Model Content
