1 is an internal configuration diagram of a switchboard as an example of a conventional enclosure.

In the case of the enclosure, due to vibration generated when an earthquake occurs, a bus bar or electric power device, which is a power transmission means assembled inside the enclosure, is damaged or broken due to impact caused by vibration.

Accordingly, a vibration damping device for preventing damage and failure due to vibration occurring during a disaster such as an earthquake or typhoon is provided in a housing such as a switchboard.

However, the vibration damping device installed in the existing enclosure is generally equipped with a spring or rubber, etc., and has a structure to absorb vibrations generated during disasters such as earthquakes or typhoons.

However, whenever vibrations such as earthquakes or typhoons occur, springs or rubbers for absorbing vibrations in the vibration damping device on the lower side of the housing repeatedly contract and expand continuously, and when used for a long time, fatigue is aggravated and elasticity is lost. As a result, there is a problem in that the vibration damping device loses its vibration damping ability when an actual earthquake or the like occurs.

Therefore, even if the vibration damping device is used for a long time in the housing, there is a demand for a housing having a vibration damping device configured to appropriately damp vibrations caused by earthquakes while maintaining the vibration damping ability without loss.

The above Ex. The OR gate 124 is a gate whose output becomes H only when two inputs are opposite to each other {(H, L)(L, H)}, and the AND 1 gate 122 and the AND 2 gate 123 are Only when the signals output through the above Ex. It is a configuration in which a signal is output from the OR gate 124 .

In detail, a first signal conversion unit 110a that receives and converts a signal from the electronic acceleration sensor 300 is configured, and the signal conversion unit 110a includes an AV converter, an A/D converter, etc. It may be configured, the signal converted to digital in the signal conversion unit (110b) is input to the CPU (120).

In more detail, the signals converted by the first signal conversion unit 110a are respectively input to the AND 1 gate 122 and the AND 2 gate 123 of the CPU 120 .

In addition, a signal generated when the contact portion J of the first conductor plate 240 and the second conductor plate 250 is attached and detached through the conductor sphere 240a of the mechanical earthquake sensing device 200 is received and converted. The conversion unit 110b is configured.

Similarly, the signal conversion unit 110b may be configured to include an AV converter, an A/D converter, and the like, and the digitally converted signal in the signal conversion unit 110b is input to the CPU 120 .

Hereinafter, the operation configuration of the CPU 120 will be described. The signal converted to digital by the signal conversion unit 110b is input to the microcontroller 121, and the signal processing unit 121a of the microcontroller 121 receives the signal. It is configured to input different signals to the built-in latch circuit 121b when the signals respectively generated when the state of attachment and detachment of the contact portion J is input is received.

For example, when the signal processing unit 121a changes the state of attachment and detachment of the contact unit J, when different signals generated from the signal conversion unit 110b are input, for example, 1 when detaching, and 1 when attaching. A signal of 0 is input to the latch circuit 121b.

When the contact portion J of the first conductor plate 240 and the second conductor plate 250 is attached through the conductor sphere 240a, the pin 3 is sent out through the latch circuit 121b of the microcontroller 121. The obtained signal is input to the AND 1 gate 122 .

Conversely, when the contact portion J of the first conductor plate 240 and the second conductor plate 250 is detached through the conductor sphere 240a, the fourth pin is passed through the latch circuit 121b of the microcontroller 121.

As a result, when the contact portion J of the first conductor plate 240 and the second conductor plate 250 is attached through the conductor sphere 240a, the AND 1 gate 122 is output through the signal conversion unit 110a. Since both the signal and the signal transmitted from pin 3 through the latch circuit 121b of the microcontroller 121 are input, the AND 1 gate 122 outputs a high level signal.

Conversely, when the contact portion J of the first conductor plate 240 and the second conductor plate 250 is detached through the conductor sphere 240a, the AND 2 gate 123 is output through the signal conversion unit 110a. Since both the signal and the signal transmitted from pin 4 through the latch circuit 121b of the microcontroller 121 are input, the AND 2 gate 123 outputs a high level signal.

The contact portion J of the first conductor plate 240 and the second conductor plate 250 is attached and detached through the conductor sphere 240a, so that any one of the AND 1 gate 122 and the AND 2 gate 123 is attached or detached. Only high level output is generated.

In other words, when the AND 1 gate 122 outputs a high level signal, the AND 2 gate 123 outputs a low level signal, and the AND 1 gate 122 outputs a low level signal. In this case, the AND 2 gate 123 is configured to output a high level signal.

When vibration occurs in the housing 10, if an earthquake, an external shock, or a temporary shock is applied, the electronic acceleration sensor 300 transmits a signal and the AND 1 gate 122 through the signal conversion unit 110a. and the AND 2 gate 123 , and in the mechanical earthquake sensing device 200 , the metal sphere 230 comes into contact with the metal sphere 230 while moving according to vibration around the bottom of the inner housing 220 . The contact portion J of the first conductor plate 240 and the second conductor plate 250 is detachably attached to one of the AND 1 gate 122 and the AND 2 gate 123 through the conductive sphere 240a. A signal is input.

Eventually, the Ex. The OR gate 124 is a gate whose output becomes H only when two inputs are opposite to each other {(H, L)(L, H)}, and the AND 1 gate 122 and the AND 2 gate 123 are Since the signals output through the above Ex. A signal is output at a high level from the OR gate 124 .

In the earthquake occurrence determination unit 150, the Ex.
