Technical Field

New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.

[0003] A snap ring, also called a retaining ring or retaining ring, is a type of fastener used to prevent axial movement of parts on a shaft or in a hole in machines or equipment. A terminal block is an accessory used to achieve electrical connections; industrially, it falls under the category of connectors. With increasing industrial automation and more stringent and precise industrial control requirements, the use of terminal blocks is gradually rising. With the development of the electronics industry, the application range of terminal blocks is expanding, and the types are also increasing. Besides PCB board terminals, the most widely used types include metal terminals, nut terminals, spring terminals, and so on.

[0004] However, when a new energy vehicle travels on a bumpy road, the retaining ring used to connect the terminal block may vibrate, which may cause the terminal block connection to loosen. Utility Model Content

[0005] The purpose of this utility model is to provide a hyperbolic snap ring terminal for energy storage in new energy vehicles with high reliability, so as to solve the problem mentioned in the background art that when a new energy vehicle travels through a bumpy road, the snap ring used to connect the terminal may vibrate, which may cause the terminal connection to loosen.
