Description

Technical Field

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

[0002] A connector is also called a coupler. In China, it is also called a connector and a socket, generally referring to an electrical connector. That is, a device that connects two active devices to transmit current or signals. Currently, the most widely used connector is the USB connector. Among them, the most commonly used USB connector is the USB Type-C. USB Type-C, abbreviated as Type-C, is a hardware interface specification for the Universal Serial Bus (USB). The highlights of the Type-C connector are its thinner design, a transmission speed of up to 10 Gbps, and a powerful power transmission of up to 100 W. The biggest feature is that it supports double-sided insertion of the USB interface.

[0003] In order to improve the anti-interference ability of existing connectors, most of them adopt an inner shell and outer shell structure. However, there will be a gap between the inner shell and the outer shell. The existence of the gap will weaken the waterproof performance of the connector, and moisture is likely to penetrate into the connector through the gap, thereby affecting the normal use of the connector. Therefore, it is necessary to improve the existing Type-C connector. Summary of the Utility Model

[0004] In view of this, in view of the deficiencies of the existing technology, the main purpose of the present utility model is to provide a waterproof Type-C female socket connector, which can effectively solve the problem that there is a gap between the inner shell and the outer shell of the existing Type-C connector, and moisture is easily penetrated into the connector through the gap, thereby affecting the normal use of the connector.

[0005] To achieve the above object, the present utility model adopts the following technical solutions:

[0006] A waterproof Type-C female socket connector includes an insulating body, an upper row of terminal groups, a lower row of terminal groups, an inner shell, and an outer shell; the insulating body includes a tongue plate and a base; the upper row of terminal groups and the lower row of terminal groups are both arranged on the insulating body.

[0009] As a preferred solution, the rear end of the inner shell has a retracting part, which tightly abuts against the surface of the tongue plate and the front end surface of the base. The retracting part forms a hard interference with the insulating body, making the assembly of the inner shell and the insulating body more firm and reliable.

[0010] As a preferred solution, a through groove penetrating the upper and lower surfaces of the base is provided at the rear end of the base. The aforementioned upper row terminal group and lower row terminal group both pass through the through groove, and a waterproof member is filled in the through groove to prevent water from penetrating into the gap between the terminals and the insulating body.

[0011] As a preferred solution, a fixing groove is provided at the rear end of the base. The rear end of the outer shell has a limiting piece, and the limiting piece extends into the fixing groove for fixing and limiting, making the assembly of the outer shell and the insulating body more firm and reliable.

[0012] As a preferred solution, grounding feet are provided on both sides of the outer shell.

[0013] As a preferred solution, further comprising two middle steel sheets. The two middle steel sheets are both arranged in the insulating body. The hook parts of the two middle steel sheets are both exposed outside the tongue plate. The welding feet of the two middle steel sheets both extend out of the base, and the two middle steel sheets are arranged at intervals left and right and are located between the upper row terminal group and the lower row terminal group. The two middle steel sheets are both in contact conduction with the grounding terminals of the upper row terminal group and the grounding terminals of the lower row terminal group.

[0014] As a preferred solution, through holes are provided in both of the two middle steel sheets, and the through holes are buried in the insulating body, making the assembly of the middle steel sheets and the insulating body more firm and reliable.

[0015] The utility model has obvious advantages and beneficial effects compared with the prior art. Specifically, as can be seen from the above technical solutions:

[0016] By filling waterproof glue in the gap, the waterproof glue effectively isolates the moisture in the gap between the inner shell and the outer shell, so that the moisture cannot enter the connector interior through the gap between the inner shell and the outer shell, ensuring a dry environment inside the connector and ensuring that the connector can work and be used normally.
