[0002] Connectors are used to bridge blocked or isolated circuits, allowing current to flow and the circuits to function as intended. Connectors are essential components in electronic devices and are also commonly used in new energy vehicles to connect cables, power modules, and motors. However, most existing automotive cable connectors are secured using direct plug-in technology, which can easily move when subjected to external forces. Loosening the connection between the cable and connector can lead to poor contact.
