Description

INSULATED OPTICAL CABLE DIVERGENCE BOX < RTI ID = 0.0 >

The present invention relates to an optical cable branch box capable of minimizing a failure due to environmental factors.

It should be noted that the contents described in this section merely provide background information on the present invention and do not constitute the prior art.

Optical communication is a technology that transmits information by transmitting light, and it transmits optical signal having large capacity information by using optical fiber made of glass fiber as a medium. This optical communication system has the following advantages in comparison with the electrical communication system in which information is transmitted using an electric signal through a conventional copper wire.

First, because there is almost no interference by external electromagnetic waves, installation cost is economical because a distance of several tens to several hundred km can be transmitted without a repeater. Second, it can not be intercepted from the outside. Third, fiber bundles are called fiber optic cables, which can transmit and receive a large amount of information at the same time.

Therefore, there is no doubt that optical communication is the most suitable medium for data transmission such as a trunk line, a subscriber line, a submarine cable and the like, which require a large amount of information transmission and high reliability.

However, the optical fiber has a disadvantage in that the strength is relatively weak due to the nature of the material, since a transparent dielectric material such as quartz glass or synthetic resin is drawn out by elongation and elongation. For this reason, the outer surface of the optical fiber is coated with a buffering cover or the like to be formed into a cable shape.

Meanwhile, the optical cable branch box is a device for performing connection and distribution functions between the external optical line and the transmission device of the subscriber. A part of the optical fiber led into the optical fiber branching box is connected to the optical fiber of the optical adapter and is distributed to the transmission device of the subscriber in the short distance and the remaining optical fibers of the optical cable can be drawn out in the optical cable form and distributed to the transmission device of the subscriber at long distance Do.

As a prior art of the present invention, Korean Utility Model Laid-Open No. 20-2011-0005160 (May 25, 2011) discloses a photoconductor box.

Further, the space portion of the main body is provided with an optical adapter which is connected to the optical fiber in the optical cable and distributes to the subscriber side transmission device.

On the other hand, since the photonic band is directly connected to the telephone pole, damage to the photonic band is transmitted due to the lightning striking the telephone pole.

Therefore, in order to prevent this, it is general that a ground for connecting the lightning strike to the ground is connected to the telephone pole.

However, if grounding is not properly installed on the telephone pole, or if the ground is faulty, the optical cable connected to the photoconductor box is damaged due to lightning.

First, the difference in level between the lead-in space 217 and the lead-out space 218 serves as a reference in inserting the optical cable having the enclosure into the connection body 210.

Therefore, the constructor is very convenient to insert the optical cable since the optical cable is always inserted at a certain depth when inserted at the maximum without any measurement.

In addition, the optical cable introduced from the outside can be inserted with reference to the level difference, which means that the optical cable inserted in the connection main body 210 by a predetermined length can be tightened with the tightening body 220.

For example, the connection body 210 may be formed to have a length of about 70 to 75 mm. By optimizing the length of the connection body 210, the tightening operation of the tightening body 220 and the detachment of the optical cable from the connection body 210 are prevented You can give.

The difference in height between the inlet space 217 and the outlet space 218 serves as a kind of water film for preventing the water introduced into the inlet space 217 from riding on the optical cable.

Accordingly, in the present invention, the inflow of water is primarily blocked while the optical cable connection part 200 is installed at a predetermined angle and is inclined downward, and water is introduced by the step formed between the inlet space 217 and the drawing space 218 So that the passage of water into the main body 100 can be almost completely blocked.
