Description

Adapter cable based on USB Type-C

technical field

The utility model relates to a connection line, in particular to a USB Type-C-based adapter line conforming to the USB Type-C standard.

Background technique

Universal Serial Bus (Universal Serial Bus, USB) is a convenient and low-cost connection method that can connect multiple input devices at the same time, such as printers, joysticks, keyboards, mice, scanners, modems, digital cameras, portable disk devices, etc. peripheral equipment.

Recently, a new USB3.1 Type-C interface has been launched by the USB promotion organization, which has a smaller opening size (about 8.3mm×2.5mm), and can maintain the high-speed transmission characteristics of USB3.1, and can withstand the connector products. Level of 10,000 mating cycles. The biggest feature of the Type-C interface is that its shell structure no longer distinguishes the front and back, and there is no need to align it when using it, and it has the function of "positive and negative insertion".

In addition to being used to transmit data between peripheral devices and the host computer, the Universal Serial Bus can also provide the electrical power required for the peripheral devices to work. Although there are currently many peripheral devices that only use the Universal Serial Bus to transmit data and use independent power connectors to provide electrical power, some peripheral devices only use the power cord to the Universal Serial Bus to provide electrical power and do not need to transmit power. Data such as lights, chargers, heaters, heat sinks, etc. Therefore, when the universal serial bus is used to connect peripheral devices, the power requirements for the serial bus are increased, and the power of the universal serial bus in the prior art cannot bear the high power demand.
