Description

Technical Field

[0001] The utility model relates to a female socket connector, in particular to a waterproof Type-C female socket connector, belonging to the technical field of Type-C connectors. Background Art

[0002] Compared with traditional interfaces, the Type-C interface has many advantages such as video signal transmission, high-speed signal transmission, high power supply, and no difference in forward and reverse connection. It has gradually replaced traditional interfaces and is applied to major electronic product platforms. It has a smaller volume than both Type-A and Type-B, and can be used for both PCs and external devices. The Type-C interface has strong compatibility, so it has become a standardized interface that can connect all electronic devices such as PCs, game consoles, smartphones, and storage devices, and realizes the unification of data transmission and power supply.

[0003] However, at present, the waterproofing of Type-C female socket connectors mostly adopts the dispensing installation method. To ensure that the tongue plate does not shift, the installation instrument needs to have a certain accuracy, and after dispensing, steps such as baking the colloid are also required. The process is cumbersome, and the waterproof performance of the female socket connector is not ideal enough. Electronic devices are easily affected by water and damaged. At the same time, common female socket connectors usually adopt a fixed installation method, which is relatively inconvenient for assembly, thus affecting production efficiency. Content of the Utility Model

A limiting plate is arranged at the left end of the outer shell. The Type-C female socket main body includes plastic. The left end of the plastic contacts the limiting plate. A groove is opened on the outer surface of the plastic, and a sealing rubber ring is sleeved on the inner wall of the groove.

[0006] The Type-C female socket main body further includes PIN needle terminals. The PIN needle terminals are embedded in the plastic. The length of the PIN needle terminals is less than the length of the inner shell, which is beneficial to the stability of the PIN needle terminals, so that the PIN needle terminals are maintained stable under the protection of the inner shell of the inner shell.

[0007] The inner housing includes a left housing and a right housing. Auxiliary grooves are formed on the upper and lower surfaces of the left housing and the right housing. Auxiliary plates are fixed at the positions where the left housing and the right housing are fixed in the auxiliary grooves. The auxiliary plates are snap-fitted with the auxiliary grooves, and the splicing of the left housing and the right housing is completed through the snap-fitting of the auxiliary plates and the auxiliary grooves.

[0008] Connectors are fixed at the left ends of the left housing and the right housing. The other ends of the connectors are fixed to the limiting plates. Welding fixing plates are fixed to the bottom surfaces of the left housing and the right housing. One side surfaces of the two limiting plates away from each other are fixed to the welding fixing plates, and the inner housing is conveniently installed on the circuit board through the welding fixing plates.

[0009] A positioning post is fixed to the bottom surface of the left end of the plastic. The size of the positioning post is smaller than that of the welding fixing plate. The positioning post can be used for positioning during the overall installation process, avoiding the displacement and loosening of the connector during the plugging and unplugging process, and improving the service life of the Type-C female socket connector.

[0010] Rail blocks are fixed to the inner wall of the metal outer housing. Rail grooves are formed on the upper and lower surfaces of the left housing and the right housing. The rail blocks are slidably connected with the rail grooves. A clamping groove is formed on the upper surface of the metal outer housing. Groove openings are formed on the upper surfaces of the left housing and the right housing. Clamping blocks are installed on the inner walls of the groove openings. The clamping blocks are snap-fitted with the clamping groove. The metal outer housing is limited through the clamping blocks, and the left housing and the right housing are limited through the metal outer housing, thereby completing the extrusion sealing of the rubber sealing ring and improving the waterproof ability.

[0011] A limiting flange is arranged at the right end of the metal outer housing. The limiting flange is in contact with the inner housing, facilitating the assembly and limitation between the inner housing and the metal outer housing and avoiding the improper assembly position of the inner housing.

[0012] The present utility model provides a waterproof Type-C female socket connector, and the beneficial effects thereof are as follows:

[0013] 1. For the waterproof Type-C female socket connector, by placing the sealing rubber ring on the inner wall of the groove and extruding the sealing rubber ring through the inner housing after the installation is completed, the sealing is completed, avoiding the damage caused by external liquid reaching the position of the circuit board through the plastic from the connection position, and solving the problem of poor waterproof performance of the common Type-C female socket connector in the prior art.

[0014] 2. The waterproof Type-C female socket connector forms an inner housing by splicing a left housing and a right housing during use. A metal outer housing is installed on the outer surface of the inner housing to limit the inner housing and maintain its stability, achieving rapid assembly of the Type-C female socket connector and solving the problem of low production efficiency caused by inconvenient assembly of common Type-C female socket connectors.
