A fire spread prevention safety cover for a circuit breaker according to an embodiment of the present invention is a product capable of preventing a fire caused by overheating of an electronic device such as a circuit breaker 60 in advance.

To this end, the fire spread prevention safety cover for a circuit breaker according to an embodiment of the present invention may include at least one or more of the cover part 10 and the fire extinguishing part 20.

First, referring to FIG. 1 , the circuit breaker 60 may be formed in a substantially rectangular parallelepiped shape.

Wire connection parts 61 are formed on one side and the other side of the circuit breaker 60 .

The wire connectors 61 are formed at regular intervals along the longitudinal direction of the circuit breaker 60 so that the plurality of wires 80 can be individually connected.

The wire connection parts 61 are located at separate locations from each other by the partition walls 62 .

In the circuit breaker 60 by the partition wall 62, an empty space 63 is formed at regular intervals in a partitioned structure.

The partition wall 62 is formed with a rail groove 64 formed in a substantially 'ㅗ' cross-sectional shape.

On the other hand, the cover part 10 may include a horizontal part and a vertical part bent in a right angle direction at an end of the horizontal part, and may be formed in a substantially 'L'-shaped cross-sectional shape.

In the lid part 10, additional slider parts 11 are formed at positions corresponding to the rail grooves 64, respectively.

The additional slider part 11 is formed in a 'ㅗ' cross-sectional shape to correspond to the rail groove 64.

Therefore, when the additional slider part 11 is slidably coupled to the rail groove 64, it does not escape, and as a result, the cover part 10 also maintains a state of being coupled to the circuit breaker 60.

And, when the cover part 10 is coupled to the circuit breaker 60, it covers the wire connection part 61.

In addition, the cover portion 10 is formed with the same number of passage holes 10a passing the wires 80 connected to the wire connection portion 61 as the wire connection portion 61 .

Due to the cover part 10, it is possible to minimize the amount of dust flowing into the wire connection part 61, and thereby, the amount of dust deposited on the wire 80 connected to the wire connection part 61 can be minimized.

That is, when dust is applied to a certain area of the wire 80 connected to the wire connection part 61, a fire may occur when overheating occurs in the circuit breaker 60, but a fire for the circuit breaker according to an embodiment of the present invention The anti-diffusion safety cover can reduce the probability of fire occurrence by minimizing dust contact with the electric wire 80 through the cover part 10.

On the other hand, the fire extinguishing unit 20 is configured to be initially extinguished when a fire occurs in the circuit breaker 60 .

The fire extinguishing unit 20 may be formed of microcapsules having a predetermined size or less.

At this time, as an example, the microcapsules may be set by attaching an adhesive means 90 such as double-sided tape to the inner wall surface of the cover part 10 and then applying a plurality of them to one surface of the adhesive means 90.

As another example, the microcapsules may be set by applying paint to the inner wall surface of the cover part 10 and then applying a plurality of microcapsules to the paint.

Microcapsules are capsules containing an extinguishing agent, an epoxy resin for film formation, and an activating compound (complex).

A fire occurs in the circuit breaker 60 mainly at a connection point between the wire connection portion 61 and the wire 80. At this time, in the fire spread prevention safety cover for a circuit breaker according to an embodiment of the present invention, the microcapsules are disposed facing the connection point of the wire connection part 61 and the wire 80 on the inner wall surface of the cover part 10.

Therefore, when a fire occurs, the microcapsule reacts immediately and spreads the fire extinguishing agent widely so that the initial fire can be effectively extinguished (extinguished).

In particular, even if a fire occurs at the connection point between the wire connection portion 61 and the wire 80, since the flame is immediately extinguished by the fire extinguishing agent of the microcapsule, the spread of the fire can be more effectively blocked.

At this time, the microcapsule may be formed in a type in which fire extinguishing gas is ejected as the particles burst in response to chloride in case of fire.

This type of microcapsule particle is microencapsulation (a technique of inserting liquid, gas, or solid into microcapsules) of micro-active agents (5 to 10 μm) into micro-size capsules with a diameter of 5 to 20 μm. By applying, it is inserted into the micro cap, and the micro-extinguishing agent corresponding to the extinguishing agent uses hydrofluorocarbon prepared from a halogen compound, so that the fire can be extinguished by restrained cooling.

Due to this, it is possible to prevent a large-scale fire from occurring, and it is possible to safely protect the circuit breaker 60 or a power supply device such as an outlet located nearby from fire.

Next, another embodiment of a fire spread prevention safety cover for a circuit breaker according to an embodiment of the present invention will be described with reference to FIGS. 4 and 5 .

4 is a diagram showing an example in which a slider part and a cover part are applied to a fire spread prevention safety cover for a circuit breaker according to an embodiment of the present invention, and FIG. 5 is a fire spread prevention safety cover for a circuit breaker according to an embodiment of the present invention.
