Description

Outlet Safety Cover {SAFETY COVER FOR RECEPTACLE}

The present invention relates to an outlet safety cover that opens and closes a plug insertion hole using a rotating plate, and has a complementary material for preventing the plug from being loosely inserted due to the thickness of the switch and the outlet safety cover which can reposition the rotating plate after removing the plug. It relates to an outlet safety cover provided.

In general, an outlet refers to a device that is connected to indoor wiring of electricity to insert a plug in order to supply power to an electric appliance. It is roughly classified as a multi-outlet that can be used by connecting electrical appliances.

The basic structure of such an outlet has a ground copper plate inside the body and a terminal rod insertion hole is formed in the upper part of the body. When a user inserts the terminal rod of the plug into the terminal rod insertion hole, the terminal rod of the plug is connected to the ground copper plate of the outlet. It will flow.

However, since the terminal rod insertion hole is always exposed to the outside, and there is no protection device between the terminal rod insertion hole and the ground copper plate, when a curious child inserts a conductor such as chopsticks, it is usually connected to an electric shock accident.

In addition, when using electrical appliances where dust is accumulated, electric sparks may splash on the dust or electricity may flow into the dust, resulting in a fire that will lead to a fire. It is possible to accumulate and be exposed to the risk of fire.

In order to prevent such electric shocks and fires, a cover may be attached to the outlet of the existing outlet, but the practical effect is small due to the inconvenience and frequent loss of removing the cover every time the electrical appliance is connected.

In addition, there has been a study on the structure of the outlet to prevent electric shock, but it is rarely installed because of the high cost because the structure is more complicated than the general outlet.

In order to solve this problem, the outlet safety cover for opening and closing the terminal rod insertion port by the rotation of the rotary plate was developed.

The safety cover is to allow the insertion of the plug by opening the terminal rod insertion hole of the outlet by rotating the rotating plate using the terminal rod of the plug only when using the plug and the terminal rod of the outlet, usually by the rotary plate.

However, the conventional rotary safety cover has a problem in that when the plug is inserted and used, the restoring force of the elastic member acts on the rotating plate, and the terminal rod is tightened by the rotating plate.

11 and 12 illustrate a general type of plug. Recently, as shown in FIG. 11, only the tip 12e of the terminal rod 12 is made of metal so as to prevent electric shock from the terminal rod 12. And the middle (12m) is a plug 10 composed of an insulating material, such as plastic is used a lot, such a plug 10 has a layer between the tip (12e) and the middle (12m) when the plug 10 is pulled out The terminal rod 12 is often caught by the rotating plate to be restored.

 Furthermore, as shown in FIG. 12, in the case of the plug 10 including the recess 12g on the outer circumferential surface of plastic, which is frequently used, the terminal rod 12 is excessively caught by the rotating plate, and the plug 10 is excessively applied. When unplugged, it is a fact that damage occurs in a safety cover such as a rotating plate.

In addition, the conventional rotatable safety cover has a problem that the plug inserted into the outlet is loosely fixed because the length of the terminal rod is shortened due to the thickness of the safety cover.

Accordingly, an object of the present invention is to provide an outlet safety cover including a switch so that the restoring force of the rotating plate is not disturbed when the plug is removed to solve the above-mentioned problems.

In addition, another object of the present invention to provide a socket safety cover including a complementary material so that the plug is not loosely inserted due to the thickness of the safety cover.

An outlet safety cover according to the present invention for achieving the above object is made of a rotating plate and a lower plate body including an upper plate body with a plug guide hole and an insertion hole into which the plug terminal rod is inserted, and the outlet is rotated by the rotating plate. The terminal rod insertion hole of the opening and closing, the rotation of the rotary plate when the terminal rod insertion hole is opened to block the force of the elastic portion to block the insertion hole by rotating the rotary plate in place, after removing the plug and the user's operation of the elastic portion A switch for releasing the force to block the terminal rod insertion port is fixed to the rotating plate.

According to the outlet safety cover according to the present invention, when the rotating plate is rotated for use, the rotating plate is fixed and the plug terminal is inserted into the outlet because of the thickness of the switch and the outlet safety cover to return the rotating plate by the user's operation after removing the plug By providing a complementary material to compensate for the shortening of the rod length, the plug is not disturbed by the rotating plate when the plug is unplugged, and there is no problem that the plug is loosely inserted into the outlet.
