Universal socket

Abstract

The invention discloses a universal socket. The socket includes a housing, insulators in the housing and plug clamping pieces L and N, wherein the plug clamping pieces L and N are installed in holes Land holes N of the insulators respectively. The socket is characterized in that the holes L and the holes N are through holes in the independent insulators respectively, and one end of each hole L orN serves as a plug hole; the insulators are installed on bases and matched with the bases; partial outer surfaces of the plug holes of the insulators are circular and are embedded in circular holes in the housing; the universal socket also includes a transformer with at least two groups of wiring ends, the plug clamping pieces L and N can be electrically connected with each group of wiring ends by rotating the insulators, and the plug clamping pieces L and N can be simultaneously electrically connected with only two corresponding wiring ends of the same wiring end group respectively. According to the socket, merely by means of simple operation, the voltage demands of different types of sockets for different types of appliances can be met at the same time, and moreover the universal socketalso has the advantages of being simple in structure, low in cost and convenient to use and operate.

Description

technical field [0001] The invention is a universal socket. Background technique [0002] At present, the plugs, sockets and voltage standards of countries all over the world are different, but the common shapes of L holes and N holes are: China, the United States and Japan, double ‖ shape, but the voltage in China is 220V, while that in the United States and Japan is 110V . In the UK, it is: a horizontal line, and its standard voltage is 240V. This leads to people who go abroad to carry conversion plugs, on the one hand to adapt to the different sockets, on the other hand, to adapt to the requirements of different voltages. However, people who don't know the situation go abroad, or forget to carry the conversion socket when they go abroad, especially if the conversion plug is lost when they are abroad, it will bring great trouble to the personnel abroad, and even delay travel or work. In fact, the need to carry additional conversion plugs is a troublesome thing in itself...
