Technical Field [0001] The present invention relates to an optical cable connecting terminal box,

The present invention relates to an optical fiber cable connection terminal box for connecting an optical fiber cable and an optical jumper cord extended to a building, an apartment or a house of a subscriber, and is particularly easy to install, has excellent waterproof function, So that it can be fixed.

With the rapid development of high-speed information networks, demand for advanced information and communication services has surged, and a large number of optical cables have been installed in buildings and apartments to provide FTTH (Fiber To The Home) services.

The optical cable, which is usually extended from the installer side, is connected to the optical fiber line connection terminal box, and the optical cable is branched into a plurality of optical jumper cords inside the terminal box to provide the optical Internet service to the customer through the optical jumper cord.

On the other hand, the optical fiber cable connection terminal box is mounted on the inner or outer surface of communication equipment and communication equipment, and is located inside or outside of communication equipment and communication equipment normally installed outdoors.

In order to mount an optical fiber cable connection terminal box (hereinafter referred to as "terminal box") to communication equipment and communication equipment installed outdoors, mounting brackets should be installed in the terminal box. In order to install the mounting brackets, mounting holes should be formed in the terminal box .

On the other hand, since the terminal box is located outdoors, it is required to be waterproof and moisture-proof. However, as described above, since the mounting hole is formed in the terminal box, it is difficult to expect waterproof property and moisture-proof property.

1 is a rear perspective view showing a back surface of a terminal box according to the related art, and FIG. 2 is a conceptual view showing the inside of a terminal box.

As shown in FIG. 1, a plurality of mounting holes 1H are formed on the back surface of the terminal box 1 to fix the mounting bracket 10. Since the holes 1H are formed in the terminal box 1, the waterproof and moisture- There is a drawback that this remarkably falls.

2, the optical fiber 3 inserted into one side of the terminal box 1 is in a state in which the cover is removed and the exposed optical core 3C is connected to the optical cable 3 inserted into the other side of the terminal box 1 3 and the remaining part of the optical core 3C is connected to the adapter 20 mounted on the terminal box 1. [

The adapter 20 is disposed through the terminal box 1. The optical core 3C is connected to one end of the adapter 20 located inside the terminal box 1 and the adapter 20 Is connected to an optical jumper cord 40 extending to the consumer side.

On the other hand, inside the terminal box 1, the optical cores 3C are stored inside the terminal box 1 in a state of being wound with a radius of curvature of at least the required minimum radius of curvature.

However, depending on the position of the adapter 20 and the position of the sleeve 30 connecting the optical core 3C of the optical cables 3, it can be wound and stored with a radius of curvature smaller than the internal minimum radius of curvature of the terminal box 1. [

Experienced workers may be able to roll the optical core to a radius greater than or equal to the minimum radius of curvature by experience and awareness, but in the case of unskilled persons, the optical core may be wound with a radius smaller than the minimum radius of curvature required, have.

In this case, when the door of the terminal box 1 is closed, the optical core 3C is caught and broken, or the like. There is a problem.

Korea Patent Registration No. 10-1093439 (December 19, 2011)
