[PROBLEMS] To provide a fuse switch capable of controlling a power supply and protecting a circuit. SOLUTION: Two power terminals 1P and 1M are separately provided at the bottom end of a hollow concave tank 11 of a switch body 10, and one separated fixing plate 20 is installed at one of the power terminals. A spring plate 21 is provided at the upper end of the fixed plate 20, and a fuse plate 22 made of bimetal is provided at the lower end of the fixed plate. A spring plate mass 30 is pivotally connected between the spring plate 21 and the fuse plate 22 so as to be active. At the upper end of the spring plate 21, a control mass 40 interlocked with the splash plate mass 30 is pivotally connected in an active manner. A sliding tank 41 is provided in the control block 40, and a splash block 51 of the push button 50 is provided.
It is connected to the end. Therefore, when the fuse plate 22 is overloaded, deformation occurs, and the splash plate mass 30 is
Can be restored to its original position and the power can be turned off, so that the power can be reliably controlled and the circuit can be protected.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a power switch, and more particularly to a fuse switch that can control power from a power supply.

[0002]

[Prior art]

 A conventional general switch has two conductive plates that are separated and conductive at the bottom at the inner end of the switch body, one splash plate is provided between the two conductive plates, and extends to the outer end of the switch body. It was connected to a push button to control conduction or electrical disconnection between two conductive plates.

[0003]

[Problems to be solved by the invention]

 However, in the above-described configuration, the slab only connects and connects two conductive plates, and when the load is excessive, it is extremely easily damaged. In order to increase the practicality of the configuration, the edge of the outer plate is improved, one metal plate is installed, and the ON / OFF control of the two conductive plates is automatically performed under the bimetallic temperature sensing condition. It is carried out. However, such a configuration cannot be widely used because the life of the slab is greatly reduced because the slab is always turned on and automatically deformed to control the operating direction of the slab. Therefore, a main object of the present invention is to provide a fuse switch capable of controlling a power supply and protecting a circuit.

[0004]

[Means for Solving the Problems]

 According to the fuse switch according to the first aspect of the present invention for achieving the above object, two power terminals are separately provided at the bottom end of the hollow recessed tank of the switch body, and one of the power terminals is provided at one of the power terminals. Install one separate fixing plate. A spring plate is provided at the upper end of the fixed plate, and a bimetal fuse plate is provided at the lower end of the fixed plate. A spring plate is pivotally connected between the spring plate and the fuse plate so as to be freely movable. At the upper end of the spring plate, a control lump that is linked with the spring lump is pivotally connected freely. A sliding tank is provided in the control block, and is connected to the end of the push button. Therefore, if the fuse plate is overloaded, it will be deformed, and the splash plate mass can restore the control mass to its original position and cut off the power supply, so it is necessary to control the power supply reliably and protect the circuit. Can be.

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, two power terminals 1P and 1M are installed at the bottom end of the hollow concave tank 11 of the switch body 10, and one separated fixing plate 20 is provided on one side of one power terminal 1M. . One spring plate 21 and two metal fuses 22 are separately provided at the upper and lower ends of the fixed plate 20, and one spring plate mass 30 is installed between the spring plate 21 and both metal fuse plates 22 in active pivot contact. I do. At the upper end of the spring plate 21, another control block 40 interlocking with another spring plate block 30 is installed in active pivotal contact to form one continuous rod device. In addition, one slide tank 41 is installed in the control block 40, and is connected to the end of the splash block 51 of the push button 50. Thus, a switch structure having one fuse device can be formed.

Next, as shown in FIGS. 2 and 3, when the push button 50 is not used under normal conditions, the front and rear of the spring plate 21 are separated from the power supply terminal 1 P to form an OFF state. I have. After the push button 50 is pressed, the push button 50 slides the control lump 40 and receives the swing motion control of the tank 41, pushes the front and back of the spring plate 21 and comes into contact with the power terminal 1 P to form an ON energized state. . If the load on the entire circuit is large during energization, the fuse plate 22 is deformed and pushes one end of the plate mass 30, and the other end of the plate mass 30 presses the control mass 40 to restore the original shape. Return to position to create an OFF state for the electrical circuit and protect the circuit. During the entire operation, the load can be protected because the spring plate 21 and the fuse plate 22 have their own characteristics and functions. This can extend the service life of the switch.

As described above, according to the fuse switch of the present invention, it is possible to reliably control the power supply according to demand and protect the circuit.
