Description

Optical cable connection divergence box

The present invention relates to an optical cable splicing box, and more particularly, to an optical cable splicing box which can increase the sealing force by double sealing and can use a ribbon cable that is a trunk network.

In general, an optical cable is an optical cable that converts an electrical signal into a light signal and transmits the same through a glass fiber. The shape is cylindrical and consists of a core, a clad, a jacket, and the like. Shims are optical fibers made of very thin glass or plastic.

Clad is a kevlar fiber to withstand strong forces around the glass fiber. Its main component is the light pulse of glass fiber, which is not disturbed by the external current and is covered with glass, plastic, etc. which has different optical characteristics from the core. The jacket is the outermost layer around the fiber bundle and is made of a material such as plastic to prevent moisture, abrasion and damage.

It transmits a signal-coded light beam to internal reflection, which has a wider bandwidth than other wired transmission media, resulting in a high data rate. In addition, since the size and weight are small, the supporting structure can be reduced in size and transmitted in the form of light, thereby preventing external interference such as impact noise and crosstalk. The data rate is about 1 Gbit. It is widely used in local area and wide area network, long distance communication, military use, and subscriber line.

The optical communication cable junction box in which the optical communication cable is connected and branched to each other is composed of two half-moon fluorescent lamps and a cover, and the optical cable guide part formed in the cover is formed in a tubular structure, so that the optical cable is inserted into the tube in order to insert the optical cable into the tube. After cutting the tip of the optical cable, inserting the optical cable, sealing it with a thermocompression tape on the outer periphery, and heat-shrink it again to maintain airtightness. It has been pointed out that the sealing force is remarkably dropped due to the large number of joints, and various foreign substances penetrate into the inside, which reduces the call sensitivity. Moreover, the work efficiency is inferior because the work can be completed only through various processes. .

In order to solve such a conventional problem, the present applicant proposed a sealing device for an optical cable junction box, which was applied for a patent registration on February 25, 1998, and registered as a patent No. 255054 on February 10, 2000. In the center, a metal fixing member for fixing the main holder extends inward, and a cable guide portion for inserting and supporting the incoming optical cable and the outgoing optical cable at the outer periphery of the fixing member protrudes inward and outward, and the screw portion at the outer periphery. The inner threaded portion is formed by screwing a cap nut in which a seal is inserted into the inner circumference, and the outer threaded portion is interleaved with the inner circumferential seal and cuts a predetermined portion of the end portion to integrally fasten a fastening member having a knurled portion on the inner circumferential surface as a bolt. Is configured to screw on the cap nut, which is joined together with a screw. A sealed cover; The fixing member provided at the central portion of the sealing cover has a plurality of fastening holes formed at one end thereof, and a through hole formed at one side of the “c” shaped bracket and the connecting member configured to stack the rearranging panels stepwise. A main holder fixed by using; An alignment plate for arranging the branch lines of the optical cable in the center of the upper surface and arranged on the both sides of one end of the rear panel by mating stepwise to match the fastening holes formed in the bracket by using elastic clips formed with projections on the outside; The outer circumference of the opening panel, which is integrally combined with the main holder, is provided with a recess for inserting the sealing seal on the outer circumference of the opening, and on the outside for matching with the flange formed on the outer circumference of the sealing cover to mate as a bolt. The flange portion is provided and the outer periphery has a configuration in which the deformation preventing boss for adapting to the change in the external temperature is extrapolated to the enclosure at equal intervals.

However, the conventional sealing device of the optical cable junction box is composed of a sealing member between the sealing cover and the enclosure with a sealing member and screwed together to place the sealing on the outer surface of the optical cable. Type cable had a problem that can not be used.

The present invention is to solve the conventional problems as described above, an object of the present invention is to provide an optical cable junction box that can increase the sealing force by double sealing and can use a ribbon-type cable that is a trunk network.
