Abstract
The utility model discloses a universal random-insertion type USB plug comprising a plugging chip which is used for installing plug transmission core wires and a plugging shell which is used for fixing the plugging chip. The plugging chip is arranged in the exact middle of the plugging shell. Multiple plug transmission core wires are divided into two groups which are symmetrically installed on the two surfaces of the plugging chip. A central axis, which is parallel with the plug transmission core wires, in the plugging chip acts as the axis of symmetry, one of the plug transmission core wires in the first group and one of the plug transmission core wires in the second group, wherein the plug transmission core wires in the first group and the second group are mutually symmetrical, are connected via conductive wires to act as a corresponding output end of the USB plug. The process of reverse insertion of the USB plug is equivalent to the process of symmetry with the central axis of the plugging chip as the axis of symmetry so that the plug transmission core wires can be correspondingly connected with socket transmission core wires in a one-to-one way when the universal random-insertion type USB plug is inserted into a USB socket from any direction, and thus a universal random insertion function is realized and application is facilitated.

Described in the utility model undirectedly comprise for the grafting chip of plug transmission heart yearn being installed and for the insertion shell of fixing described grafting chip with inserting formula USB plug, described grafting chip is positioned at the center position of described insertion shell, and many described plug transmission heart yearns are divided into the two sides that two groups of symmetries are installed on described grafting chip; The central axis parallel with described plug transmission heart yearn in described grafting chip of take is symmetry axis, wherein described plug transmission heart yearn of symmetrical first group and second group wherein between a described plug transmission heart yearn, by wire, connect and as the corresponding output of described USB plug.
In said structure, grafting chip is placed in to the center position of insertion shell, can realizes USB plug and no matter which direction insert the function that all can insert smoothly with; Because the process that USB plug is oppositely inserted be equivalent to the to peg graft central axis of chip is that symmetry axis carries out symmetrical process, so originally undirected, with slotting formula USB plug, no matter which direction to insert USB socket with, its plug transmission heart yearn all can transmit heart yearn with socket and connect one to one.
Particularly, described first group of plug transmission heart yearn comprises the first cathode power supply line being arranged in order, the first negative pole data wire, the first anodal data wire and the first anode power cord, described second group of plug transmission heart yearn comprises the second anode power cord being arranged in order, the second anodal data wire, the second negative pole data wire and the second cathode power supply line, described the first cathode power supply line is connected by wire with described the second cathode power supply line and as the cathode power supply output of described USB plug, described the first anode power cord is connected by wire with described the second anode power cord and as the negative power supply output of described USB plug, described the first anodal data wire is connected by wire with described the second anodal data wire and as the anodal data output end of described USB plug, described the first negative pole data wire is connected by wire with described the second negative pole data wire and as the negative pole data output end of described USB plug.This structure is applicable to apply four maximum line USB plug.
As required, the output stube cable of described USB plug or USB flash disk circuit board.
The beneficial effects of the utility model are:
Described in the utility modelly undirectedly with slotting formula USB plug, no matter which direction to insert USB socket with, its plug transmission heart yearn all can transmit heart yearn with socket and connect one to one, thereby realizes undirectedly with plugging function, is convenient to application.
Accompanying drawing explanation
