Description

Multi-core optical connector

The present invention relates to a multi-core multi-core optical connector, and more particularly to a bundle of a multi-core optical connector that is easy to combine the core wire at the time of the binding and branching of the multi-core optical cable, the work process is simple.

In general, optical communication is an exchange of information by transmitting light. An optical fiber made of glass fiber, that is, an optical cable, is a medium, and can transmit tens of thousands of times more information than electric communication by current coaxial cable. have.

In addition, since the transmission state of the information is good because it is not influenced by radio waves from the outside and the electromagnetic at all, it is widely used in the communication field, and its use range is gradually expanding to other fields.

These cables will run on tracks hundreds of kilometers or more, with splitters, fiber amplifiers, or fiber connectors in the middle of the cable's connection branch.

In recent years, due to the rapid spread of information, more optical cables have been required, and recently, optical cables have been used to process a lot of information by making a ribbon optical cable in which an optical fiber is integrated into a strip. Such a multi-core optical cable requires branching or connection of the cable on the line, so a multi-core optical connector is also required.

Since the optical fiber is manufactured with a very small diameter (125㎛), it is not easy to actually connect the fiber cores with each other. In particular, all the cores of the ribbon-type optical cable should be properly connected in the line of the optical cable, but if any one of the cores of the optical cable is not properly connected, a connection failure will occur.

However, most of the multicore fiber connectors are designed so that the cores of the structural fiber cables are correctly connected. However, the fiber connectors of the multicore fiber cable are influenced by the environment of the place where the fiber cables are installed. When this misalignment occurs, there is often a problem that a communication failure occurs that causes transmission or loss of light (signal) to be lost or interrupted. In addition, since the core wire of the optical cable is mainly installed in the ground or in the pipeline and the sea floor, the environment of the installation place is often poor during the connection and branching of the fiber connector or the maintenance of the cable. Cable maintenance is very difficult. Therefore, when connecting and branching the fiber connector, it is necessary to arrange or arrange the connector concisely like the terminal box of the communication device. This is a very important matter in the maintenance of the optical cable later, or in identifying the cable route. It is desirable to perform the optical cable installation process.

Accordingly, various optical fiber connectors for fiber connection have been developed according to such demands. An example of a fiber connector for optical cable connection has been disclosed in detail in Patent Application No. 95-38970, Patent Application No. 95-71047, and Utility Model Registration Application No. 96-5085.

As an example, a conventional optical fiber connector disclosed in Patent Application Nos. 95-38970 will be described with reference to the accompanying drawings.

1 is an exploded perspective view illustrating a fiber connector for connecting a conventional optical cable, wherein reference numeral 10 is a pair of plugs to which a boot 12 to which an optical cable is coupled is coupled, and 20 is a plug 10. An adapter for connecting the plug 10, 30 is a case for fixing the plug 10 and the adapter 20. Reference numeral 40 is an exhaust plate.

The plug 10 is coupled to the boot 12 made of a resilient material formed with a guide 15 through which the optical cable 60 is inserted into one side, and the guide 15 of the boot 12 slides on the other side. The ferrule 16a is coupled to allow the core wire 61 extending from the optical cable 60 to be coupled to the through hole 18. Fin holes 15 are formed at both sides of the ferrule 16a.

The adapter 20 is formed so that the alignment hole 22a penetrates inside, and guide pins 24 are formed at both sides of the alignment hole 22a on both sides.

The case 30 is a guide hole is formed on the bottom surface in one side is open, the reinforcing member 32 is formed on both sides of the guide groove 34 is coupled, the elastic member 36 is coupled to both sides Grooves are formed.

The discharge plate 40 has a discharge pin is coupled to the bottom surface and a bending hole is formed in each corner.

The guide pins 24 are inserted into the pin holes 15 on both sides of the adapter 20 so as to be symmetrical with each other of the plug 10 to which the optical cable 60 is coupled. At this time, the ferrule 16a in which the core wires 61 are arranged is inserted into and fixed in the alignment hole 22a and contacts the core wire 61 arranged in the ferrule 22a on the other side. In addition, when the guide 14 of the boot 12 is inserted into the guide groove 34 of the case 30 while the plug 10 is integrally coupled to both sides of the adapter 20, the plug 10 and the adapter 20 ) Is built into the case 30. Since the elastic member 36 presses one side of the plug 10 embedded in the case 30, the plug 10 on both sides is prevented from being retracted from the adapter 20. The 61 can be prevented from being separated.

The optical fiber optical connector coupled in such a configuration has a case after fixing the plug 10 to which the optical cable 60 is connected to the adapter 20 as shown in FIG. 2 at the time of binding and branching of the optical cable 60. The core wire 61 may be connected by coupling the optical cable 60 so that the optical cable 60 is not separated by the elastic force of the elastic member 36 of the 30.

However, as the use of the optical cable increases, the number of core wires increases, so that core wires arranged on the ferrules of the plugs are mixed or entangled, which makes it difficult to work during maintenance of the wires, and the assembly structure of the plug and adapter In the coupling, there is a complex end using a guide pin or the like of the adapter.

Therefore, the present invention has been devised to solve the above-mentioned problem.
