Abstract

The invention discloses a data transmission interface, apparatus and system. The data transmission interface comprises a connector used for connecting terminal equipment and a magnetic field shielding layer, wherein at least one data receiving-sending chip connected with the connector is wrapped with the magnetic field shielding layer; and the data receiving-sending chip performs data transmission between the terminal equipment and other equipment through signal lines in the receiving-sending chip. According to the data transmission interface, the outer layer of the chip for the data transmission is wrapped with the magnetic field shielding layer for shielding magnetic field interference so as to reduce radial component in the data transmission and to further reduce interference on the data transmission.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a data transmission interface, device and system. Background technique [0002] At present, in order to realize wireless transmission, a USB (Universal Serial Bus, universal serial bus) interface is usually used as an interface of a wireless transmission device such as WiFi to connect with a terminal device to realize wireless data transmission between the terminal device and other devices. [0003] However, since the transceiver IC chip of the USB interface has radiation during signal transmission on its signal line, this causes an impact on signal transmission. Contents of the invention [0004] The object of the present invention is to provide a data transmission interface, device and system to solve the technical problem that the signal line in the USB interface has radiation which affects the signal transmission in the prior art. [0005] In view of this, the pr...
