Waterproof electrical connection device

The present invention relates to an electrical connection device, and more particularly to a waterproof connection device.

Universal Serial Bus (USB) is a technical specification for input and output interfaces. Its biggest feature is to support hot swap and plug and play, and in addition to transmitting data, it can also transmit current for power supply. Therefore, it is widely used in communication products such as personal computers and mobile devices, and is also further used in electronic products such as monitors, digital televisions (on-board boxes), game consoles, and the like. Among them, the USB 3.1 electrical connector of the new Type-C interface has faster data transmission rate and higher power efficiency than the previous Type-A interface or Type-B interface USB 2.0 electrical connector, and the Type-C interface. The USB 3.1 electrical connector has an upper and lower symmetrical appearance, which allows the user to eliminate the need to distinguish the plugging direction. It is expected to be the mainstream specification of the USB in the future.

However, for industrial computers installed in industrial sites, monitors that must be subjected to wind and rain due to installation in the outdoors, etc., such as electronic products installed in harsh environments, even if these electronic products are used with high transmission and The Type-C interface electrical connector of the power supply rate, but the Type-C interface electrical connector will still cause contact failure or even damage due to factors such as oxidation due to moisture, dust accumulation, etc., thereby losing its data transmission and power supply. effect.
