[0002] Among the connector types commonly used in various electronic products, Universal Serial Bus (USB) connectors are the most widely used, including USB 2.0, USB 3.0, Micro USB, Mini USB, and USB Type-C. The USB Type-C connector features the ability to simultaneously charge and transfer data, and its reversible pluggable port enhances ease of use. As a result, the USB Type-C connector is widely used in various electronic products.

[0003] For example, Chinese Patent No. 106654648 discloses a structurally stable USB Type-C receptacle connector comprising a main housing with ears extending outward from both sides of the main housing. Each ear has a screw hole, and the main housing is secured to an electronic device by locking a screw in the screw hole. However, the main housing is typically made of plastic, which is relatively weak. When the connector is subjected to significant external forces, the ears can easily break and damage, affecting the locking force between the connector and the electronic device and affecting the stability of signal transmission through the connector.
