Description

electrical plug

The present invention relates to an electric plug, and more particularly, to an electric plug capable of making furniture or home appliances in close contact with a wall surface as much as possible and improving space utilization.

An electrical plug is a type of electrical wiring device and is a connection device that is provided at the end of a cord connected to an electrical device and used by being plugged into an outlet. In general, electricity entering a home or factory leads to an outlet, and the electric appliance is operated by supplying electricity to the electric appliance by plugging the electric appliance into the outlet.

At this time, the plug has two pins (connection pins) connected to the cord in a connection part with the outlet, for example, the plug body, and is inserted and fixed into the outlet hole to supply electricity to the electric appliance.

That is, the general structure of the plug includes a plug body and a pair of connection pins provided on the front surface of the plug body. According to this configuration, the connection pins provided on the plug body are connected to a connection hole provided on the outlet. This makes it possible to supply power to home appliances.

In this case, the connection pin is connected to the wiring, and the wiring is connected to the electric device, so that the power supplied from the connection pin may be supplied to the electric device through the wiring.

On the other hand, the plug can be largely classified into two types according to the shape of the plug. First, a “straight plug” in which the connection pin and the wiring are arranged in a straight line, and second, the connection pin and the wiring are at a right angle. It can be classified as a "right-angled plug" arranged as
