Abstract

The invention provides a USB connecting apparatus, a USB structure and a terminal. The USB connecting apparatus comprises a first impedance matching apparatus and a second impedance matching structure; one end of the first impedance matching apparatus is connected with a first differential signal pin of a universal serial bus (USB) interface while the other end is connected with the first connecting end of a printed circuit board (PCB); the first connecting end of the PCB is connected with the first differential signal connecting end of a processor; one end of the second impedance matching apparatus is connected with a second differential signal pin of the USB interface while the other end is connected with the second connecting end of the PCB; and the second connecting end of the PCB is connected with the second differential signal connecting end of the processor. By adoption of the USB connecting apparatus, improvement to connecting impedance mismatching of a USB data line is realized, so that anti-interference property is further improved and distortion probability is lowered.

Description

technical field [0001] The invention relates to electronic technology, in particular to a USB connection device, a USB structure and a terminal. Background technique [0002] The universal serial bus (Universal Serial Bus, USB) interface circuit has the advantages of fast transmission speed, convenient use, support for hot plugging, flexible connection and independent power supply, etc., and is currently widely used in mice, keyboards, printers, scanners, chargers, Interface modules for external devices such as digital cameras and mobile hard disk lights. In the application of the USB interface circuit, it is necessary to maintain sufficient transmission power under the configuration of impedance matching, and reduce the impact on the working state of the device itself after being connected to the load. [0003] In the prior art, the length of the differential line is shortened by arranging the USB chip as close as possible to the USB socket, and the shorter differential li...
