Waterproof USB Type-C female seat connector

Technical Field

The utility model relates to the technical field of USB Type-C female socket connectors, in particular to a waterproof USB Type-C female socket connector.

Background

USB Type-C is an USB interface appearance standard, has a smaller volume than both Type-A and Type-B, and can be applied to interface types of PC (host device) and external device (slave device such as mobile phone). The most intuitive advantage of Type-C is to get rid of the trouble of the plug wire thoroughly, the design of the front and back pluggable interfaces with excellent natures can not cause misplug or damage to parts caused by misplug. More importantly, the Type-C interface has strong compatibility, so that the Type-C interface becomes a standardized interface capable of connecting a PC, a game host, a smart phone, a storage device and expanding all electronic devices, and unifies data transmission and power supply, for example, two display devices are tightly combined together through a Type-C line for use. In addition, type-C supports the USB3.1 standard. The standard power supply is 100W at maximum, and the voltage and the current are improved; the coding consumption is reduced from 20% of 3.0 to 3%. In other words, the user can rapidly transmit data and video through Type-C or charge more rapidly. The standard also allows the user to charge other devices with their own cell phone. For the display, when the Type-C is used for data transmission, a power line is not needed to be additionally used for supplying power to the display, the problem that desktop wires are messy is solved, and even the HDMI and DP interfaces at the relatively high end cannot be used.
