Description

Technical Field

[0001] This invention relates to a two-in-one USB connector, and more particularly to a two-in-one USB connector that offers double the improvement in charging and transmission performance. Background Technology

[0002] Universal Serial Bus (USB) is a globally universal standard connector that includes male and female connectors. By inserting the male connector into the female connector, electronic devices can be connected to external devices to transmit control commands, multimedia data, and power.

[0003] In recent years, the Type-C standard electrical connector has been developed. This type of electrical connector has no insertion direction restriction, so users no longer need to distinguish between the front and back of the USB. That is, the Type-C electrical connector can be inserted in either direction and provides relatively high transmission efficiency. It also has many advantages such as small size, so it is widely used in electronic devices.

[0004] However, conventional Type-C connectors are all single-port connectors with a maximum current rating of 5 amps (A). When used in charging devices, this results in insufficient current transmission, making them unsuitable for charging high-power products.

[0005] Therefore, the problem that this invention aims to solve is to provide a Type-C USB connector with twice the charging and transmission efficiency. Summary of the Invention
