Patent ID: 6893267

Claim:
A USB plug with a multi-directional rotation structure, adopted for a portable electronic device and mating with an electronic product having a USB port; the USB plug comprising: a main body having a first pivotal portion connecting an end thereof, the first pivotal portion including a first hollow housing having semi-spherical inner and outer surfaces, and a first mating portion formed on a free end of the first hollow housing; and a USB mating body relative to the main body, and having a second pivotal portion connecting an end thereof and a USB interface disposed on an opposite end thereof; the second pivotal portion corresponding to the first pivotal portion, and the USB interface being relative to the USB port of the electrical product, wherein the second pivotal portion includes a second hollow housing having semi-spherical inner and outer surfaces and a second mating portion formed on a free end of the second hollow housing; wherein the second hollow housing has an internal diameter longer than an external diameter of the first hollow housing, and the second hollow housing is loosely matched with the first hollow housing for the first hollow housing to be wrapped partially and loosely inside the second hollow housing; the second hollow housing has an aperture diameter formed concentrically with the second mating portion and shorter than the external diameter of the first hollow housing, in order to prevent the second hollow housing from escaping out of the first hollow housing; and the second hollow housing has a retaining rim contacting and sliding on the first hollow housing for adjusting a relative displacement therebetween, whereby the second hollow housing can be manipulated with no angular limitations and rotated in multiple directions.
