Meanwhile, the vibration damping plate 110 may be made of vibration-proof rubber in an embodiment.

Here, the vibration damping plate 110 made of vibration-proof rubber provides a composition having excellent absorption and sound insulation properties, including raw rubber, a filler, and an activator.

Raw material rubber uses both natural rubber and synthetic rubber, and as synthetic rubber, butadiene rubber with high rebound elasticity and low copper ratio is mixed with butadiene rubber with excellent flexibility.

Accordingly, by optimizing the mixing ratio of natural rubber and butadiene rubber, the effect of improving the same ratio of rubber materials is obtained.

The raw rubber is used together with 60 to 80 parts by weight of natural rubber and 20 to 40 parts by weight of synthetic rubber, and by optimizing the blending ratio of natural and synthetic rubber, the effect of improving the magnification of the material without loss of physical properties of the material is maximized can do.

In addition, although the mixed use of natural rubber and butadiene rubber as a raw material rubber has an effect of suppressing vibration and noise, the phenomenon such as a decrease in tensile strength and a decrease in heat aging resistance due to the mixed use with butadiene rubber is reduced by using fillers and other additives. It is solved through selection and content control.

As the filler, carbon black having an average particle diameter of 65 to 85 nm is used, and it is preferable to use 20 to 60 parts by weight based on 100 parts by weight of the raw rubber. When carbon black is less than 65 nm, there is a limit to vibration performance, and when it exceeds 85 nm, there is a limit in improving mechanical properties, so it is used within the above range.

In addition, if the amount of carbon black is less than 20 parts by weight, there is a limit to the increase in hardness, and if it is more than 60 parts by weight, there is a limit to carbon black dispersion, so it is preferable to use it within the above range.

In addition, in the present invention, carbon nanotubes (a-CNTs) into which one or more active groups selected from the group consisting of a carboxyl group, a hydroxyl group, an ether group and an ester group are introduced are used. At this time, the carbon nanotube (a-CNT) has a diameter of 5 to 15 nm, a length of 20 to 60 nm, and a surface area of 150 to 250 m ² /g, containing 3 to 7 parts by weight of an oxygen element. it is preferable More preferably, the carbon nanotube (a-CNT) has a carboxyl group (-COOH) and a hydroxyl group (-OH) in a weight ratio of 1:3 to 4 used.

As in the present invention, when a carbon nanotube having an activating group containing 5 to 7 parts by weight of oxygen is used as a filler as a filler, the effect of satisfying mechanical properties such as tensile strength and elongation as well as improvement of vibration performance of the vibration-proof rubber material Therefore, it is effective to use 0.5 to 3 parts by weight based on 100 parts by weight of the raw rubber. When the amount of carbon nanotubes is used in less than 0.5 parts by weight, there is a limit to the improvement of mechanical properties, and when it is more than 3 parts by weight, there is a limit in carbon nanotube dispersion, so it is preferable to use it within the above range.

The activator serves to activate the crosslinking accelerator, and in the present invention, at least one selected from the group consisting of zinc oxide (ZnO) and stearic acid (staricacid) is used. In addition, it is preferable to use the activator in an amount of 1 to 3 parts by weight based on 100 parts by weight of the raw rubber. When the amount of the active agent is less than 1 part by weight, there is a problem in that the sulfur crosslinking reaction is slow, and when it is more than 3 parts by weight, the crosslinking reaction rate is too fast, so there may be a problem in productivity.

The operation of the enclosure for communication facilities having the earthquake-proof and vibration-proof function according to the present invention of the configuration as described above will be described with reference to FIGS. 3 to 5 again.

In case of vibration and shock caused by mechanical vibration or earthquake to the housing 100, the vibration of the vertical force causes the housing 100 and the vibration damping plate 110 to vibrate in the vertical direction together, and the vibration is the support plate 120. The shock is absorbed while compressing the compression spring 138 around the bolt shaft 132 supported by the support 124 of the .

At this time, by using the nut 134 and the washer 135 of the bolt shaft 132 , the elevating vibration is limited to some extent, and the ball 132a of the bolt shaft 132 is a hemispherical receiving groove 124a of the support part 124 . ), the left and right flows can be flexibly replaced to some extent as they come into contact with the clouds.

And the vibration by the horizontal force, it is possible to attenuate the impact by the connecting means (140).

As the first link section 144 and the second link section 147 rotate around the hinge connection part 148, the distance between the first hinge member 142 and the second hinge member 146 increases and then moves away. , the first hinge member 142 may be horizontally moved along the first guide hole 113a like the first movable body 142a.

As such, the second hinge member 146 may also be horizontally moved along the first guide hole 113a like the first movable body 142a, and the first link section 144 and the second link section 147 are 2 It may also be possible to move in the longitudinal direction through the long hole (147a) formed on the link section (147).

Accordingly, the housing 100 can be protected without mutual interference by using the horizontal direction vibration as the connecting means 140 of the four sides as the first and second guide holes 113a and 122a and the long holes 147a.

Due to the above-described functions, it is possible to safely protect the equipment inside the telecommunication facility by minimizing the transmission of external force or vibration to the internal device even when vibration and shock caused by mechanical vibration or earthquake that occur all the time are generated.

In addition, it is possible to stably support the housing from the seismic force of both the horizontal force and the vertical force in the vertical direction acting on the housing when an earthquake occurs.
