Title:
DOUBLE-SIDED PLUG HAVING A QUADRANGULAR FRAME
Document Type and Number:
WIPO Patent Application WO/2011/087282
Kind Code:
A3
Abstract:
The present invention relates to a double-sided plug which has a quadrangular frame coming into contact with and being supported on the inner surface of a connecting port, and thus is firmly inserted into and connected to the connecting port by preventing easy separation of the plug from the connecting port due to an accidental shock, and allows terminals to be stably connected to corresponding ground pins for a long period of time without much difficulty. The double-sided plug according to the present invention comprises: a quadrangular frame inserted into the connecting port in a way that the outer surface thereof makes contact with and is supported on the inner surface of the connecting port; a hard substrate arranged at the inner center of the quadrangular frame; and four terminals (V, D+, D-, G) arrayed symmetrically to one another on both sides of the substrate. As such, although the plug may be inserted into the connecting port in any direction, the four terminals arrayed on one side of the substrate are connected, respectively, to the four ground pins on the connecting port, and the four terminals arrayed on the other side of the substrate can be connected without short circuiting by making no contact with a tension ground pin provided at the connecting port.
