The invention relates to a USB de-concentrator which is provided with five de-concentrating units distributed at intervals. Each de-concentrating unit includes a USB female port, fixed elastic pieces, a golden finger, and a golden finger attachment plate, wherein the upper and lower sides of the USB female port are both equipped with the fixed elastic pieces, the golden finger attachment plate is arranged in the middle of the upper and lower fixed elastic pieces corresponding to each other, and the golden finger is arranged on the golden finger attachment plate. The USB de-concentrator has the following beneficial effects: (1) because of spaced distribution and double-sided socket design, the probability of correct insertion is ensured, and the work efficiency is improved greatly; (2) the foldable design makes the USB de-concentrator easy to carry, effectively prevents dust from entering, and improves the cleanliness during use; (3) the compact design makes the USB de-concentrator small and light, the USB de-concentrator is divided into upper and lower space layers during use, and the problem of congestion caused by too many interfaces in the same layer is reduced; and (4) an independent indicating lamp design is adopted, the indicating lamps display the working states of the corresponding positions during working, and the indicating lamps flash when in normal operation.
