Abstract

end. The technical field to which the invention described in the claims belongs

Earth leakage breaker with plug

I. The technical problem the design is trying to solve

The conventional earth leakage breaker is attached to the wall or panel, so it has a closed end to check all the loads connected to the load side terminal at the time of switch trip, and it is mandatory to use the earth leakage breaker by connecting electric machinery. However, it is too wasteful to use a circuit breaker for each load individually.

All. Summary of solution of the design

The present ground fault circuit breaker can be used for individual load because it is easy to install and detach the plug in the conventional ground fault circuit breaker, and the ground fault circuit breaker can be used as in the conventional or plugged into a general outlet.

The present invention relates to an earth leakage circuit breaker equipped with a plug, and more particularly, to an earth leakage circuit breaker that enables the plug to be easily installed or detached from the earth leakage circuit breaker.

Conventional earth leakage breaker has no choice but to directly connect the wires to the load side terminals of the earth leakage breaker and detect the load of individual loads such as electric tools and home appliances. It's a dangerous and cumbersome task. Therefore, a ground fault circuit breaker equipped with an outlet such as Korean Utility Model Publication No. 95-25854 has been conceived as a method for facilitating the connection of individual loads to the ground fault circuit breaker, but the ground fault circuit breaker also has a wall or panel like the conventional ground fault circuit breaker. It can be used by plugging in individual loads while they are attached.

However, the circuit breaker used by attaching it to the wall or panel is also connected to the load side terminal, so the switch is tripped by the short circuit, short circuit, etc. of all the loads connected to the load side terminal. There is a problem in that all connected loads must be checked.

In addition, in industrial sites, when workers use electric machine tools, they are difficult to install and are cumbersome, so they only need to attach a plug to the end of the input wire of the power tool and plug it into a terminal box or outlet to prevent accidents. Due to frequent occurrence, the government obliges the use of earth leakage breakers connected to electric machinery by complying with Article 329 of the Rules on Industrial Safety Standards. However, it is too wasteful to install and install an earth leakage breaker daily for each individual load. Even if the lamp is plugged in, it is possible to identify the electric leakage of the load individually and to reduce the electric shock accident. Moreover, since the mounted plug can be detached, it can be attached to the wall or panel like the conventional earth leakage breaker. It can provide.

If described in detail by the accompanying drawings the configuration of the present invention as follows.

The earth leakage breaker 10 of the present invention allows the plug 20 to be mounted in front of the power supply terminal 12 of the earth leakage breaker 10 by a fastening means such as a screw, and the plug blade 22 of the plug is directly or an electric wire. The plug blade 22 and the power supply side terminal 12 can be energized with each other by being connected to the power supply side terminal 2 by a conductive means such as the like.

An embodiment of the present invention for this purpose is as follows.

In the conventional ground fault circuit breaker, the screw insertion hole 11 is drilled so as to pass in a straight line from the front to the rear of the ground circuit breaker 10, but the screw insertion hole 11 of the power supply terminal 12 for inputting power. Must pass through the center.

This is for the plug blade 22 of the plug 20 mounted in front of the earth leakage breaker 10 to be in line with the power supply terminal 12, and this is also a plug blade having the coupling hole 22a. (22) is screwed by the screw 30 through the screw insertion hole 11 from the back of the body of the earth leakage breaker (10), so that the power supply terminal (12) and the plug blade (22) are energized. At the same time, the plug 20 is to be mounted on the earth leakage breaker 10.

As such, the present invention earth leakage breaker 10 capable of mounting and detaching the plug 20 can be used by plugging into any outlet, and may form an outlet for the 220 and 110 volt outlets 15 in the lower part of the body. It is very easy to use in home appliances.

In this way, the earth leakage breaker is easy to install and detach the plug, so it is possible to attach it to a wall or panel like a conventional earth leakage breaker in places where the plug cannot be used. It is not only very easy to use individual electric tools or home appliances but also to prevent accidents caused by short circuit and short circuit for each load.
