[0002] Generally, connectors are used as connecting elements for electronic signals and power supplies and their accessories. Their main function is to provide connections between various electronic devices or equipment and to ensure accurate signal transmission. Connectors have developed into various types depending on the products, power, and usage environment. They can be used in computers, servers, computer peripherals (such as keyboards, mice, or printers), peripherals of vehicle hosts (such as car computers or satellite navigation), telecommunications or communication equipment, and household appliances.

[0003] Existing high-power CRPS power connectors generally include terminals and an insulating body. The terminals are inserted from one end of the insulating body.
