Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a current distributor which has a built-in wiring breaker for shutting off an overcurrent in a current distributor such as a dup and has a current disconnection alarm display attached.

[0002]

[Prior art]

 Normally, the electric circuit installed in a building is structured so that if an overcurrent flows through one circuit and the electric capacity exceeds that, all of that circuit will be cut off, so it is used in that circuit. All the electric currents of the electric products were cut off, and it was very inconvenient for the electric products that had to keep the current flowing in the same electric circuit, because the usage condition could not be maintained.

Conventionally, current distributors have been widely spread and used as simple current distributors such as taps even in general households, and can be seen in any household and are indispensable. In modern society, in particular, every household has a wide variety of electrical products, and even children's toys are not functioning unless they use regular electricity.

However, there is a limit to the number of outlets installed in each building and each room, and the number of outlets installed is absolutely insufficient as compared with the electric appliances owned by the owner. Is. As a result, there are more opportunities to use current distributors such as taps in order to use many electrical products, resulting in the extended distribution and use of electrical cords from one tap to many electrical products.

[0005]

[Problems to be solved by the device]

 The present invention automatically suppresses the current flowing through one current distributor to within the rated current, prevents damage to equipment and the like due to overcurrent, and prevents accidents such as fires at the initial stage, and the same electrical circuit. It is intended to retain the functions of other electric appliances used in. In other words, one current distributor always displays the allowable current within the rated range, but using a current above the rated current puts a heavy burden on the current distributor, causing heat generation, etc. There is a danger of equipment damage and fire, etc. However, since electricity is an indispensable source of energy in modern society as a simple energy source, in reality, one current distributor is used for wiring to many electric appliances, Few people are aware of the danger.

Further, when the so-called octopus wiring is commonly used, a large load due to overcurrent causes an accident such as a fire from the current distributor, causing great damage or even loss of human life. In many cases, it is very difficult to make one current distributor recognize that only a specified current can be used, and this has become a major social issue in terms of the safe use of equipment.

In addition, since an overcurrent flows through one tap or the like, a built-in wiring breaker is automatically activated to cut off the current, so that the current interruption alarm lamp is turned on. In that case, it is possible to recognize that a lot of load is applied to the taps that are being used.Therefore, reduce the number of electrical products currently wired from the current distributor to reduce the amount of electricity used. If the circuit breaker is switched on again after the number of contacts has been reduced, the structure shall be easy to handle and easy to return to the original usable state immediately. Also, when recovering, the recovery switch of the wiring breaker built into the current distributor should be provided with a function that allows easy recovery operation from the outside.

[0008]

[Means for solving the problem]

 This plan has a built-in wiring breaker that shuts off the current even if a small overcurrent of about 13 amps flows in a current distributor such as a tap. The current is split into two, one of which is always energized to the tooth part of the output electrode of one of the taps, and the other one is automatic only when an overcurrent flows to the circuit breaker. The current flows only when the contacts move and switch.

Then, only when the overcurrent flows, the wiring breaker is automatically operated and the current interruption alarm display lamp is turned on.

Since the present invention is configured as described above, the current divider has a built-in wiring breaker having a function of automatically blocking the overcurrent, so that the overcurrent always flows. It is possible to confirm that the current supply to the electric appliances currently in use is stopped by the current disconnection alarm display lamp.

[0011]

【Example】

 The present invention will be described with reference to the drawings. A non-fuse-type circuit breaker for wiring that has a function of automatically blocking an overcurrent from one wiring (2) on the input current primary side inside the current distributor (1) Attach (3).

Then, the input primary side current is branched into two poles in the circuit breaker for wiring, and one pole is connected to one of the current output tooth portions (4) of the current distributor. The other pole of the circuit breaker is connected to the primary side of the current interruption alarm display lamp (9). Further, the secondary side (6) of the current interruption alarm display lamp and the current input teeth (7) other than (4) are connected. Then, the wire connecting (6) and (7) is connected to the wire on the input current side (8) other than (2). The wiring breaker in (3) is designed so that current always flows in the direction of (4) in normal use, but when an overcurrent flows in (3), the contacts automatically move ( A current flows in the direction of 5) and the current supply to (4) is cut off. When the current flows to (5), the current cutoff alarm indicator lamp that did not light up when the current flows to (4) lights up, and it can be confirmed that the current does not flow in the direction of (4). It is a thing.

[0013]

[Effect]

 With the above configuration, a phenomenon that cannot be visually recognized even when a current is normally in danger due to an overcurrent flowing through a current distributor such as a tap is confirmed by checking the current interruption alarm indicator lamp. It can be confirmed that the current flows and the current is cut off. As a result, it is possible to prevent the risk of equipment damage or fire leading to a serious accident, and to automatically cut off the current without knowing the allowable amount of electricity for a single equipment. It is expected that people who have little knowledge of electric appliances and how to use them can use various electric appliances with peace of mind.

In addition, there are many electric appliances that do not fully exhibit their functions unless they are constantly energized, such as an electric timepiece. If you plug in an electrical outlet and apply an electric current, it will be left as it is semi-permanently.Therefore, there is a possibility that you will not notice until a fire occurs due to the tracking phenomenon at the plugged-in part. Seed fires are increasing. However, by using this current distributor with overcurrent protection, an overcurrent protection device works before an overcurrent flows to cause a fire, and it is possible to prevent such a fire case.

Furthermore, although the society is aging, there are few people who handle it according to the manuals for electric products. For this reason, most people have used it appropriately based on past experience, and many people do not notice it until an accident occurs. However, once electricity is turned on, electricity flows forever unless the switch is intentionally shut off.Therefore, there is always the danger of an accident.Therefore, use this current divider with overcurrent protection. This makes it possible to ensure the safety of current flow that is not directly visible.

[0016] Recently, the number of households that are away from home due to mutual income from couples is increasing. Of course, it is expected that a person will be connected, but if a person is nearby, some kind of response is possible, but in the case of an unmanned person, the response is completely impossible and the accident It will lead to expansion. However, by using this current distributor with overcurrent protection, it is possible to prevent accidents from occurring from the current distributor such as taps.
