Type-C connector consists of the following three parts:
1. Insulation part. The insulating part is also called the Type-C connector base or mounting plate. Its main function is to enable the wires or pins to be fixed at the position required by the design without shaking at will. At the same time, it can also act as an insulator to prevent contact that should not be made. partially isolated.
2. Contact part. The contact part is one of the basic components of the electrical connector and plays the function of electrical connection in the electrical connector. In the USB low-speed transmission era, the contact part transmitted current and ordinary signals, but in the high-speed transmission era, the contact part is also responsible for guiding electromagnetic waves.
3. Shell part. The main function of the shell part is to protect the connector. It cannot affect the signal information received by the Type-C interface, but it can shield electromagnetism and reduce electromagnetic interference on the connector.
The contact part of the Type-C connector is one of the basic components of the electrical connector and plays the function of electrical connection in the electrical connector.
In the era of USB low-speed transmission, the contact part transmits current and ordinary signals. In the era of high-speed transmission, the contact part is also responsible for guiding electromagnetic waves.
Therefore, the contact part is crucial to the function of the Type-C connector.
The working principle of Type-C connector mainly includes three aspects: physical layer connection, signal transmission and power consumption control.
In terms of physical layer connection, Type-C adopts a reve-rse insertion design, that is, the guide pins inside the connector will automatically identify and adjust when connecting, making it more convenient for users to use and improving the stability of the connection.
In terms of signal transmission, Type-C uses two symmetrical data channels, which can support bidirectional transmission at the same time. It also adopts an ultra-low power consumption mode, which greatly reduces the energy consumption of the interface during the transmission process.
Type-C also has some additional functions, such as being able to connect to devices with video output functions to achieve multimedia transmission and support the transmission of audio signals, allowing users to enjoy multimedia entertainment such as music and movies.
