BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electric connection apparatus, and more particularly, to an electric connection apparatus which can easily detach an electric plug and a socket with one hand and can prevent an electric shock accident.

Electric plugs (hereinafter referred to as "plugs") and electrical outlets (hereinafter referred to as "outlets", hereinafter referred to as "outlets" It is used everywhere and it is a commodity that can not be found in modern life. As shown in FIG. 1, such plugs and outlets are classified into about 14 kinds of shapes, and they are not standardized in each country.

It is inconvenient to have a multi-plug so that it can be used in the outlet of a country when traveling abroad in each country.

As shown in FIG. 1, the receptacle has at least two or more connection ports, and the receptacle has at least two electrode rods for insertion into each connection port.

In Korea, the plug is also equipped with two circular electrodes because the outlet has two circular connection ports.

However, in the conventional outlet, since the connection port into which the electrode rod is inserted is exposed to the outside, there is a problem that electric discharge accident, fire or the like occurs due to the fact that young children pierce the chopstick into the connection port with curiosity.

Especially, 61% of child electric shocks occurred in the last 5 years are serious enough to cause accidents.

In addition, since a conventional outlet and a plug have at least two connection ports and an electrode rod, all the connection ports and the positions of the electrode need to be exactly matched so that the outlet can be mounted on a narrow corner, a desk, In the case where it is located at a place too high or low, narrow, or dark, the connection port of the outlet is not visible to the user's eyes.

That is, since the overall shape of the plug is formed in a round shape and the receptacle is formed with a seating groove having a corresponding shape, when the electric plug and the receptacle are mounted only by themselves, In order to position it accurately, it was only possible to mount it by turning the plug for a long time.

In addition, when a plug is attached to an extension socket such as a multi-tap, not a wall outlet, it is very inconvenient to separate the plug with one hand while holding the socket with one hand in order to separate the plug. There is a problem that it is very difficult to detach.

In addition to this, in the work site where welding, drilling and the like are performed, plugs and receptacles must be removed several tens to hundreds of times a day. However, the problems described above cause a problem that the worker's fatigue is greatly increased and the working time is increased .

Also, there is a high risk of fire, such as occurrence of spark due to contact failure due to elastic disappearance of terminals to which the electrodes are contacted.

Conventional technologies related to plugs and outlets have been described in "Outlet (Protective Patent No. 10-1573492) " and" Outlet for preventing electric shock and plug (Patent No. 10-1571397) " Is known.

However, although it is possible to prevent electric shock in the prior arts such as " outlet with protection means for preventing foreign objects from entering the socket and preventing electric shock "and" socket and plug for preventing electric shock, " Remains.

Korean Patent No. 10-1573492 (November 25, 2015) Korean Patent No. 10-1571397 (November 18, 2015)

On the other hand, the conventional electric outlet has a disadvantage that it is very difficult to separate the electric plug with one hand when the electric plug is detached, so that it is necessary to use both hands. Therefore, the electrical outlet C according to the present invention can be provided with the separation auxiliary unit 800 so that the user can easily separate the electric plug P with only one hand.

The separation auxiliary unit 800 may be provided in the electrical outlet C or the electrical plug P and applies a force to push the mounted electrical plug P in the direction opposite to the insertion direction. That is, in a state where the electric plug P is not mounted, an external force is applied in a pushing direction when the electric plug P is mounted without generating any external force.

Accordingly, when the electrode plug 300 is brought into contact with the terminal unit 600 by inserting the electric plug P into the mounting portion 510 and then rotating the electrode plug 300, the separation auxiliary unit 800 applies a pushing force to the entire electric plug P The electrode rod 300 and the terminal unit 600 are more closely adhered to each other to maintain a stable state and when the electrode rod 300 is positioned in the opening portion 710 by rotating in the opposite direction to separate the electric plug P It is possible to separate the electric plug P from the separation auxiliary unit 800 very easily by applying a pushing force to the electric plug P. [

This separation assisting unit 800 includes a ground terminal 810 and an elastic member 830 as shown in Fig.

The ground terminal 810 is positioned below the ground hole 530 and contacts the ground bar 200 inserted through the ground hole 530 to escape the leakage current or the like and is supported by the elastic member 830.

In the embodiment of the present invention, a grounding hole 530 is formed by applying an outlet body 500 of a non-conductive material such as plastic, and a cylindrical guide pipe 530, which extends vertically downward from the end of the grounding hole 530 (540) was applied.

The inner diameter of the guide pipe 540 corresponds to the outer diameter of the ground bar 200, the length thereof is smaller than the length of the ground bar 200, and the end thereof is open. Therefore, the ground bar 200 inserted through the ground hole 530 passes through the guide pipe 540 and protrudes downward.

The guide tube 540 has a hollow inside and a ground terminal 810 having one side opened and the opposite side closed. The guide tube 540 is inserted into the ground terminal 810 .

A predetermined spacing space 820 is formed between the ground terminal 810 and the inner bottom surface of the electrical outlet C and the ground terminal 810 is kept spaced apart by the elastic member 830.

When the ground bar 200 is inserted through the ground hole 530, the end of the ground bar 200 is pressed downward by contacting the closed surface of the ground terminal 810, and the elastic member 830 is compressed, The position of the terminal 810 is lowered.

In this state, when the electric plug P is rotated to complete the mounting, the elastic force of the elastic member 830 applies a constant pushing force to realize the above-mentioned effects. In order to separate the electric plug P, The position of the ground terminal 810 is rotated by the elastic force of the elastic member 830 and the ground bar 200 is pushed out to help the electric plug P easily fall out.
