Description

{Concentric Plug with Fire-Extinguishing Function}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an outlet having a fire extinguishing function, and more particularly, to an outlet having a fire extinguishing function capable of automatically extinguishing a powder fire extinguishing agent by fire when an internal fire occurs.

Generally, various electric and electronic products used in homes, offices, factories, etc., are connected to an outlet that is installed in a building in order to receive electric power.

The power line connected to the outlet is connected to a circuit breaker which is automatically operated when an overcurrent occurs to block the supply of electric power, thereby preventing fire or electric and electronic products from being damaged due to overcurrent.

However, dust and moisture accumulate in the outlet and electricity is generated. In the case of tracking fire caused by the heat and flame generated at this time, a fire occurs even under the allowable current amount. In this case, since the overcurrent is not generated, the breaker does not operate, and it is impossible to prevent the tracking fire by using only the breaker.

Generally, when a fire occurs, it is best to extinguish the fire near the fire point in the early stage of fire.

In recent years, some techniques have been proposed for an outlet that can be extinguished in the early stage of a fire by incorporating a fire extinguishing device therein.

For example, Korean Patent Publication No. 10-1011709 discloses a socket outlet having a fire extinguishing means for extinguishing a fire when a spark occurs at a power supply terminal or a fire occurs due to a leakage current.

The fire extinguishing means includes a compression container in which the extinguishing gas is filled, and a blocking member that opens the opening of the compression container so that the extinguishing gas is diffused to the ignition point when the temperature rises above a certain temperature.

Since the digestion means is filled with the digestion gas in the compression vessel, there is a possibility that the digestion gas will leak out when the pressure inside the compression vessel rises due to shaking during storage, transportation and use. If a minute leakage of the compressed gas occurs at the installation site of the blocking member or the like, the fire extinguishing function can not be sufficiently exhibited in the actual fire, and it is difficult to confirm whether or not the compressed gas has leaked in the compression vessel.

In the case where the compressed gas is leaked in the above, there is a problem that the initial evolution does not occur when an actual fire occurs.

Korean Patent Publication No. 10-0840245 discloses a technique for a multi-tap in which a lid having a fire extinguishing space in which a fire extinguishing liquid is stored is provided.

In the lid of the multi-tap, a wall surface constituting the fire extinguishing space part is melted by the ignition heat so that the fire extinguishing liquid is ejected to the ignition part.

In the case of the above-described multi-tap, a lid is required, so that when the installation space is not sufficient, it is not possible to use it and causes a rise in cost.

In addition, the above-described multi-tap is not only difficult to evolve since it is a structure in which the fire extinguisher is dispersed after the fire is transferred, and is also plugged by the plug, so that the fire extinguishing liquid is ignited at the fire point Which occurs in the terminal portion).

The present invention provides a socket having a fire extinguishing function which is provided near a fire point so that the fire extinguisher is configured to cover the fire point immediately after the fire and the initial fire is surely performed, There is a purpose.

A socket having an extinguishing function according to an embodiment of the present invention includes a box-shaped case having a mounting space formed therein, and a terminal member having a plurality of female terminals, And the surface facing the female terminal is made of a thin film or a thermoplastic synthetic resin film which is easy to burn or dissolve in heat and is provided with a powder fire extinguishing agent And the like.

The female terminals may be configured as a pair or a plurality of pairs.

The fire extinguishing member is preferably disposed on the left and right sides of the female terminal in a plan view, so that when the fire extinguishing is performed in any direction, the powder extinguishing agent is effectively poured to the fire point and covered.

Alternatively, the fire extinguishing member may be disposed so as to surround the respective female terminals in the upper, lower, left, and right sides.

The fire extinguishing member can be formed into a bag or box shape.

According to the socket with the fire extinguishing function according to the embodiment of the present invention, since the surface facing the female terminal is formed by a thin film or thermoplastic synthetic resin film which is easy to burn or thermally melt, When the ignition occurs, the surface of the extinguishing member rubs or melts, and the powdery extinguishing agent packed therein is poured toward the ignition point, and the extinguishing agent is effectively covered with the extinguishing agent, so that the extinguishing agent is initially extinguished.

Further, according to the outlet having the fire extinguishing function according to the embodiment of the present invention, it is possible to manufacture and install the fire extinguishing member with a simple structure and low cost, so that the fire extinguishing function can be effectively provided It is possible to do.

According to the socket of the present invention having the fire extinguishing function according to the embodiment of the present invention, since the fire extinguishing member can be installed by effectively utilizing a small space, the size and structure of the existing socket can be used as it is.

According to the outlet having the fire extinguishing function according to the embodiment of the present invention, since the powder fire extinguishing agent is used, the extinguishing agent does not leak or leak to the outside unless a large external force is applied to the case of the outlet.
