One by one pushes into the terminals 34 and 44 to be completely inserted, and the first and second terminal rods 12 and 14 of the present invention are inserted into the terminal rod insertion portion 4a of the outlet 4.

As described above, when the power cord C is twisted according to the use of the electronic product in a state in which the present invention is coupled between the plug 2 and the outlet 4 of the electronic product, the second rotating body having the plug 2 coupled thereto. (26) (28) is rotated together with the plug (2) in the direction in which the power cord (C) is twisted around the first rotating body (16) (18) coupled to the outlet (4). The twist of the power cord C is loosened by itself.

In the above, the second rotary bodies 26 and 28 rotate at an angle between 0 ° and 360 ° in a clockwise or counterclockwise direction according to the twisting direction or the degree of twist of the power cord C. The whole 26 and 28 are rotated in any direction or at any angle, so that the first semi-circular metal strip 40 and the second semi-circular metal strip 50 mounted on the inner surface of the receiving space 20 of the first case 26 are rotated. ) Is always in contact with the first and second circular metal bands 36 and 38 of the first and second rotating bodies 16 and 18, which are rotation axes. Regardless of the direction of rotation or the angle of rotation, the + terminal rod 2a of the plug 2 has a first connecting terminal 34 → a first connecting terminal 42 → a first semi-circular conductor band 40 → a first circular conductor band. (36) → The electrically conducting state of the first terminal rod 12 is always maintained through the path of the first conductor piece 38, and the negative terminal rod 2b of the plug 2 is connected to the second connection terminal 44. → second connection terminal 52 → second half Type conductive strip (50) → second is a second terminal bar 14 and always maintains the energized state through the path of the circular conductive strip (46) → second conductor piece (48).

Accordingly, the user does not need to pay attention to the power cord C not to be twisted during use of the electronic product.

Although the present invention has been described above by being limited to one embodiment, various changes and modifications may be made by those skilled in the art without departing from the technical spirit of the present invention.

For example, the positions of the first and second terminal bars and the first and second through holes may be interchanged. Specifically, the first and second terminal rods are mounted on the second rotating body, and the first and second through-holes in which the + terminal rod and the-terminal rod of the plug are inserted in the first rotating body are formed. When the cord is twisted, the twist of the power cord may be released by spontaneously rotating by rotating the power cord in a direction in which the power cord is twisted about the second rotor connected to the outlet.

In addition, the mutual coupling structure of the first rotary body of the present invention and the second rotary body having a receiving device of the janggu shape for accommodating the first rotating body is composed of a separate device as in the present invention Instead, it can be installed directly on the body of the plug or outlet.

Thus, the power cord twist prevention device according to the present invention is located between the plug and the outlet, when the power cord is twisted in accordance with the use of electronic products, the rotating body coupled with the plug rotates around the rotating body coupled to the power cord Because the twist of the power cord is released by itself, it prevents the twist between the power cord connected to one outlet in advance to prevent the disconnection of the plug and power cord connection part, and the user pays attention to the twist of the power cord during the use of electronic products. There is an effect that can be aimed at the user by not having to tilt.
