[0002] The type-c data cable refers to the data cable of the USB Type-C interface, which is a hardware interface specification of a universal serial bus. The data cable is used to connect mobile devices and computers to achieve data transmission or communication purposes. In layman's terms, it is a channel tool that connects computers and mobile devices to transmit videos, ringtones, pictures and other files. It can also be connected to a charger to charge mobile devices.

[0003] Currently, the type C flat cable on the market is 21C specification, all wires are 30AWG, the TX / RX characteristic impedance is not controlled, the power supply is insufficient, there is no high-speed pairing, and the length can only be about 600mm, so the supported length is limited. In order to extend the type cable and increase the transmission speed, this application proposes a high-speed type C extension cable. Utility Model Content

A PCB board is arranged inside the two Key-A connectors. A soldering pad is fixedly connected to one side of the PCB board. A plurality of power lines are symmetrically arranged on the outside of the soldering pad. A plurality of high-speed shielded wires are fixedly connected to the outside of the soldering pad at equal intervals. Each of the high-speed shielded wires includes a pair of wires and a shielding sleeve.

[0009] As a preferred solution of the utility model, the wire core of the power cord includes a copper wire core, and an insulating film is provided on the outer side of each of the power cords.

[0010] As a preferred solution of the utility model, the specifications of the power line and the pair of lines are both 30AWG.

[0011] The beneficial effects of the utility model are: by improving the structure to adjust the correspondence between the PCB pad and the wire, a shielding sleeve made of aluminum foil is set on the outside of the wire, and the high-frequency characteristics are controlled. Compared with the current limitations of type C line length and transmission efficiency, the product function is realized through the improvement of the above structure, so that fast charging of wires with longer lengths can be supported, and USB3.2Gen2x2 can be stably supported to meet transmission requirements.
