Description

Rotatable socket with USB interface

technical field

The utility model relates to an electrical connection device, in particular to a rotatable socket with a USB interface.

Background technique

With the gradual increase of electrical products, more and more users choose power strips to save space. Socket strips are generally used when several sockets need to be used in a certain place in the family, which can save space and save lines. However, there are still many disadvantages in the existing power strips. When the plug is too large, it will cover the jacks on the side, so that the advantages of the power strips cannot be fully reflected.

In some existing technologies, in order to increase the utilization rate of the socket, one hole of the three-hole socket is embedded between the two sockets. Although the utilization rate of the socket can be improved to a certain extent, when the plug is too large, There is still the phenomenon that the jack is covered and cannot be used. If it can be further improved on this basis, the socket module is pivotally connected to the housing, so that the housing can be rotated to change the direction of the socket on it, so as to avoid covering the socket of the socket next to it, which can improve the utilization of the socket Rate. At the same time, there are more and more mobile devices using USB charging. If a USB interface is added to the power strip, the utilization rate of the power strip will also be greatly improved.
