Description

[0001] Plug and receptacle connecting structure with a contactless power transfer structure [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plug and socket fastening structure having a non-contact type wireless power transmission structure, and more particularly to a plug and socket fastening structure having a power transmission part inside a socket main body, Electric power is transmitted, so that the risk of a serious safety accident due to electric shock can be reduced, and the electric power supply portion and the water receiving portion are built in to maintain the watertightness, Contact type power transmission structure in which a problem of difficulty in separating a plug from an outlet due to a contact due to a contact between the plug and the socket is prevented.

Generally, in a conventional socket-outlet, a power source input terminal and a ground terminal are connected to a power source input terminal and a ground terminal, and when the connection terminal plug of the plug is inserted into a socket, The ground terminal exposed on both sides is contacted with the ground terminal of the socket, thereby functioning as a power connection and grounding.

However, since the conventional power outlet has to be connected to the outlet only in one direction, there is a problem that adjacent plugs and electric wires interfere with each other when the plurality of plugs are coupled,

In addition, when the electric wires are bent or scrambled according to the position of the appliance and the socket, the user can not adjust the position of the plug but can not arrange it properly.

Further, the multi-tap is a device in which a plurality of outlets are connected in parallel and a plurality of plugs can be simultaneously inserted and used.

As the number of electric devices used in homes, offices, and the like increases, the number of receptacles required is increasing. However, installing a large number of outlets in an office or a home is neither cost-effective nor aesthetically pleasing. Therefore, most homes or offices are equipped with an adequate number or a minimum number of flush-type receptacles in consideration of the indoor size, and if necessary, additional multi-tabs are connected to the outlet.

However, when plugging in multiple plugs into a multi-tap that uses several outlets in parallel, it often happens that they interfere with other plugs plugged into adjacent outlets. This is because the intervals between the plurality of outlets constituting the multi-tap are narrow and the sizes of the plugs are different from each other. In many cases, the widest part of the plug terminal is larger than the terminal inserting port of the receptacle. In the case of outlets on the outermost side of a multi-tap, the direction of inserting the plugs may be adjusted to some extent, but in the middle of the plurality of outlets, Interference occurs.

In order to solve such a problem, a multi-tap type in which a terminal insertion port rotates and a direction can be adjusted has been developed. Korean Registered Utility Model No. 20-0185381 (Prior Art 1) and Korean Patent Laid-Open No. 10-2013-0108808 (Prior Art 2) are representative examples of rotary type multi tap.

However, since a pair of terminals are provided so as to protrude from the plug and a terminal groove is formed in the outlet so that the configuration for rotating the plug fastened to the socket plug is complicated and a large number of parts are required, And there is a serious problem that a child may insert a tongue or a pin into the terminal groove to cause an electric shock accident.

The above-mentioned invention means the background art of the technical field to which the present invention belongs, and does not mean the prior art.
