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 is that the terminal is located inside the body and the plug insertion hole is formed in the upper body, when the user inserts the terminal rod of the plug into the plug insertion port, the terminal rod of the plug is connected to the terminal of the outlet to flow the current.

However, since the plug insertion hole is always exposed to the outside, and there is no protective device between the plug insertion hole and the terminal, it is common to connect an electric shock accident when a curious child inserts a conductor such as chopsticks.

In addition, when electrical appliances are used where dust is accumulated, electric sparks may splash on the dust or electricity may flow into the dust, causing the fire to ignite, leading to fire. The reality is that you are exposed to the risk of fire.

In order to prevent such an electric shock and a fire, a cover may be attached to an existing outlet to prevent the plug from being inserted, 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, a safety cover for an outlet for opening and closing a plug insertion hole by a rotation of a rotating plate has been developed.

The safety cover is usually to prevent the plug insertion port of the outlet by the rotary plate by the elastic member, and to only insert the plug by opening the plug insertion port of the outlet by rotating the rotary plate using the terminal rod of the plug only when used.

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.

In particular, as shown in FIG. 4 (a), in order to prevent an electric shock caused by the plug terminal rod, a plug composed of only an end portion of the terminal rod as a metal (M) and an intermediate portion made of an insulating material (P) such as plastic is used. These plugs are layered at the metal (M) and plastic (P) contact portion, the terminal rod is often caught by the rotating plate acting the restoring force when the plug is pulled out.

 In addition, as shown in Figure 4 (b) in the case of a plug including a groove on the outer peripheral surface of the plastic (P), which is used a lot recently, the degree of the terminal rod is caught on the rotating plate is too severe to pull out the plug excessively, such as a rotating cover safety cover It is a reality that breakage occurs.

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.
