Abstract

PROBLEM TO BE SOLVED: To prevent a non-energizing state only of specific plug blade inserting parts even when the current goes beyond the specified current, and to allow the non-energizing state only of electrical equipment plugged into the other plug blade inserting parts, and to prevent wiping out of data of electrical equipment plugged into the specific plug blade inserting parts. SOLUTION: This electric outlet a with safety device is constituted by arranging plural plug blade inserting parts 2 connected with a power cord 3 in parallel within an electric outlet case body 1, and connecting a non-fuse bracer 4 operating before a lever of a circuit breaker comes down because the current goes beyond the specified current, between the plural plug blade inserting parts 2, 2 in parallel.

Description

DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the field of outlets with safety devices.

[0002]

2. Description of the Related Art In a conventional safety outlet, a plurality of blade insertion portions and a power switch connected to each of the blade insertion portions are arranged in parallel in a case body of the outlet connected to a power cord. A non-fuse breaker is disposed between the power cord and the power cord.

In the above-mentioned safety outlet, plugs of a plurality of electric appliances such as a rice cooker, an electric kotatsu, a fan heater, an electric pot, and a television are inserted into a plurality of blade insertion portions, and a specified current amount is exceeded. Then, the reset switch connected to the non-fuse breaker is actuated to turn off the power, so that the main power breaker does not drop.

[0004] For this reason, when the power is suddenly turned off, the data being driven into the connected personal computer and its peripheral devices is often erased. In order to restore the operation of the reset switch from the state described above, the power switch corresponding to any one of the plurality of electrical devices is switched from ON to OFF, although the main power breaker does not shut down, and the reset switch is further reset. Was pressed to turn on the power.

[0005]

[Problems to be solved by the present invention] However, the present invention
Unlike conventional safety outlets, only a specific plug blade insertion part where a special electrical device is inserted will be in a non-energized state even if the specified current exceeds only the electrical device where the plug was inserted. Therefore, even if only the electric device in which the plug is inserted only into the other blade insertion portion is in a non-energized state, the electric device has an outlet with a safety device that can be safely used without erasing data. Was developed.

According to another aspect of the present invention, there is provided an outlet a with a safety device according to the first aspect of the present invention. The blade inserts 2 are arranged in parallel, and a non-fuse breaker 4 that operates before the breaker lever falls due to an excess of a prescribed current is connected between the plurality of blade inserts 2 arranged in parallel. And

According to a second aspect of the present invention, the non-fuse breaker 4 is disposed between the first blade insertion portion 2 and the second blade insertion portion 2 near the power cord 3. It is characterized by having.

According to the third aspect of the present invention, the non-fuse breaker 4 is disposed between the second blade insertion portion 2 and the third blade insertion portion 2 near the power cord 3. It is characterized by the following.

According to a fourth aspect of the present invention, the non-fuse breaker 4 is the second or more blade insertion portion 2 near the power cord 3, and the blade insertion portion 2 and the blade insertion portion 2 are provided. And the adjacent blade insertion section 2.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the first aspect of the present invention will be described. Reference numeral a in the figure denotes an outlet with a safety device of the present invention. Reference numeral 1 denotes an outlet case body. Reference numeral 2 denotes a blade insertion portion connected to a power cord 3 arranged in parallel in the case main body 1.

Reference numeral 4 denotes a plurality of blade insertion portions 2 arranged in parallel.
This is a non-fuse breaker that is activated before the lever of the breaker is dropped due to an excess of the specified current amount connected between the two. Reference numeral 5 denotes an electromagnetic valve, and reference numeral 6 denotes a reset button connected to the non-fuse breaker 4. Code 7
Is a plug connected to the distal end of the cord 9 connected to the adapter body b inserted into the blade insertion portion 2.

An embodiment according to the second aspect of the present invention will be described. In the present invention, the non-fuse breaker 4 is disposed in the middle between the first blade insertion portion 2 near the power cord 3 and the second blade insertion portion 2.

An embodiment according to the third aspect of the present invention will be described. In the present invention, the non-fuse breaker 4 is disposed between the second blade insertion portion 2 near the power cord 3 and the third blade insertion portion 2.

An embodiment according to the fourth aspect of the present invention will be described. According to the present invention, the non-fuse breaker 4 is provided with a second or more blade insertion portion 2 near the power cord 3 and the blade insertion portion 2 and the blade insertion portion adjacent to the blade insertion portion 2. It is arranged between the two.

Reference numeral c denotes a conventional outlet, which has the following configuration. Reference numeral 10 denotes an outlet case main body, 11 denotes a plurality of blade insertion portions arranged in parallel, 12 denotes a power switch corresponding to the blade insertion portion 11, and 13 denotes a main power supply and the plurality of parallel blade insertion portions 11. This is a reset switch arranged between them. Reference numeral 14 denotes a plug attached to the end of the cord 15. 16 is a cord for electric appliances, and 17 is a plug.

[0016]

The effects of the first aspect of the present invention are as follows. According to the present invention, a plurality of blade insertion portions to be connected to a power cord are arranged in parallel in the outlet case main body, and a breaker lever falls due to an excess of a specified current amount between the plurality of blade insertion portions arranged in parallel. Since it is an outlet with a safety device to which a previously activated non-fuse breaker is connected, unlike a conventional safety outlet, only a specific blade insertion part may be de-energized even if the specified amount of current is exceeded. Even if only the electric device in which the plug is inserted into the other blade insertion portion is de-energized, the data of the electric device can be safely used without being erased.

The advantages of the invention described in claim 2 are as follows. The present invention provides an outlet with a safety device in which the non-fuse breaker is disposed between the first blade insertion portion and the second blade insertion portion near the power cord. Even if the amount is excessive, only the electric device inserted into the blade insertion portion between the non-fuse breaker and the power cord does not become de-energized, so that there is no fear of erasing data and it is safe. .

The effects of the third aspect of the invention are as follows. The present invention provides an outlet with a safety device in which the non-fuse breaker is disposed between the second blade insertion portion and the third blade insertion portion near the power cord. Even if the amount is excessive, only the electric device inserted into the blade insertion portion between the non-fuse breaker and the power cord does not enter a non-energized state, there is no fear of erasing data, and it is safe. is there.

The effects of the invention described in claim 4 are as follows. In the present invention, the non-fuse breaker may be a second or more blade insertion portion near the power cord, and the blade insertion portion may be disposed between the blade insertion portion and the blade insertion portion adjacent to the blade insertion portion. In the event that the specified current is exceeded, only the electrical devices inserted into the blade insertion section between the non-fuse breaker and the power cord are in a non-energized state. It is safe because there is no worry about erasing data.
