The invention relates to a rotating shaft type USB connection device, which includes: a data line output end and a receiving end; the receiving end includes a cylindrical chip, and the chip can freely rotate around an axis; Inside, metal tubes coaxial with the chip are equidistantly arranged; the metal tubes are blocked and fixed by insulating materials; on the part of the product shell that is in contact with the end face of the chip, concentric tubes are equidistantly arranged. Annular metal brush; on the outer surface of the chip, conductive rings are evenly arranged along its axis, and the conductive rings are matched and connected with each metal tube located inside the chip; on the surface of the output end of the data line, connected with the receiving The side contacted by the chip on the end is a semi-circular cylindrical concave surface, and conductive brushes matching the conductive rings are evenly distributed on the concave surface; the internal chip of the interface is not easy to break and damage when used, and no need to be connected. Distinguish between positive and negative.
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 the...
