Abstract

The invention relates to a spindle type USB connecting device. The spindle type USB connecting device comprises a data line output end and a receiving end. The receiving end comprises a cylindrical chip capable of freely rotating around an axis. A plurality of metal pipes coaxial with the chip are distributed inside the chip at equal intervals and are isolated and fixed through insulating materials. Concentric ring metallic brushes are distributed on the part, making contact with the end face of the chip, on a product shell at equal intervals. A plurality of conducting rings are evenly distributed along the axis of the outer surface of the chip, and are connected with the metal pipes inside the chip respectively. The face, making contact with the chip at the receiving end, of the surface of the output end of a data line is a semi-circular cylindrical concave face, and conducting brushes matched with the conducting rings respectively are evenly distributed on the concave face. When an interface is used, the internal chip is not prone to fracture or damage, and the front face and the back face do not need to be distinguished during connecting.

Description

technical field [0001] The invention relates to an accessory of a digital product, in particular to a USB interface. Background technique [0002] At present, the USB interface on commonly used digital products is a trapezoidal port, and there is a thin-plate data chip inside the trapezoidal port to connect the data line, transmit data and charge; when in use, connect the output end of the data line to the USB port correctly The internal metal sheets are tightly bonded to realize signal transmission; this kind of interface is easy to break the internal chip when using it, and it is necessary to distinguish the front and back when connecting. Contents of the invention [0003] In view of the above problems, the present invention provides a rotating shaft type USB connection device, the internal chip of the interface is not easy to be broken and damaged during use, and there is no need to distinguish the front and back sides during connection. [0004] In order to solve th...
