[0001] This utility model relates to the field of connector technology, specifically a waterproof Type-C connector female socket. Background Technology

[0002] Type-C is a USB interface standard with a smaller size than both Type-A and Type-B. It can be used in both PCs (host devices) and external devices (slave devices, such as mobile phones). For reference, see announcement number CN222785544U, which describes a waterproof Type-C connector female socket, including a housing, an injection molded body inside the housing, and a base and a tongue plate connected together. The base is fixedly connected to the rear end of the housing, and the tongue plate is located on the base near the front end of the housing. The injection molded body has a terminal group that extends through the base to the tongue plate. A sealing ring and a first stop ring are sequentially fitted on the outer peripheral wall of the front end of the housing.

[0003] The aforementioned device uses a stop ring to prevent liquid from entering the gap between the electronic device and the socket. However, the stop ring is connected by a sleeve installation method, which makes it easy for the stop ring to fall off under stress. This connection method is not stable enough, and the risk of water ingress will increase during long-term use. Summary of the Invention

The mounting shell 401 is nested and connected to the upper surface of the metal casing 1, and the first mounting foot 402 is fixedly connected to the outer surface of the mounting shell 401.

[0028] Specifically, the waterproof mechanism 2 is integrally molded by injection molding, and the installation mechanism 4 applies downward pressure to the waterproof mechanism 2. The limiting strip 204 is located in the gap between the front limiting bend 406 and the first mounting foot 402. Together with the rubber pad 201 and the mounting shell 401, it can prevent the waterproof mechanism 2 from falling off. The rubber pad 201 seals the joint on the upper surface of the metal shell 1 and compensates for the extrusion piece 101. The waterproof ring 202 seals the gap between the metal shell 1 and the external equipment.
