Description

Extraction device for ribbon optical fiber connection part

According to the present invention, a ribbon optical fiber connecting portion for extracting a ribbon optical fiber connecting portion (hereinafter referred to as a "connecting portion") from the fusion splicer safely after connecting the ribbon optical fiber core wires (hereinafter referred to as "ribbon core wire") to each other with a fusion splicer. It is about.

Referring to the accompanying drawings, a technique for connecting ribbon optical fibers to each other using a conventional fusion splicer is as follows.

FIG. 1A is a view showing a state in which a ribbon optical fiber connecting portion is drawn out from a conventional fusion splicer;

1B is a detailed view of the ribbon optical fiber.

Referring to the drawings, the fusion splicing of the ribbon optical fibers is usually carried by placing two cross-sectioned ribbon optical fibers on the fusion splicer 4 on the fusion splicer 2, and connecting the two optical fiber fibers by arc discharge. (1a) is reinforced with a heat shrink rib 17 or the like.

At this time, when the ribbon core wire connected to reinforce the connecting portion 1a of the conventional ribbon core wire is moved to the connection part reinforcing member 6 (hereinafter referred to as a "reinforcing machine"), the ribbon core wire is centered on the connecting part 1a. After both sides of (1) are pulled out by hand, the heat-shrink ribs 17 previously inserted in the ribbon core wire 1 are placed in the connecting portion 1a, and inserted into the reinforcement 6 to be reinforced.

However, the strength of the connection 1a with the coating removed is so weak that the connection easily breaks even under small torsional or tensile forces, and both sides of the ribbon core wire connected by the fusion 4 are pulled out by hand and then moved to the reinforcing device. In order to prevent the operator from twisting the connecting portion 1a or to apply a constant tension so that the two ribbon cores connected to the connecting portion can be kept in the same plane state, the connecting portion can be pulled out from the welded portion and connected to the reinforcing device. In the moving process, the connection part is cut off, or the connection part is broken within a short time by being inserted and reinforced in the heat shrinkage rib in an entangled state between the optical fibers in the connection part.

In addition, a skilled worker is required to precisely position the heat shrink ribs in the state of holding the ribbon core wires on both sides of the connection part, and the reliability of the connection reinforcement work is lowered, and much attention is required for the connection work. There are a number of problems such as delayed connection work.

Therefore, in order to solve the above problems, when the ribbon core wire connected at the welded portion of the fusion splicer is pulled out, the connecting portion is applied with a constant tension in the same plane state with the two ribbon core wires. It is an object of the present invention to provide an apparatus for extracting a connection portion of a ribbon optical fiber, which prevents a phenomenon in which the connection portion is twisted or the optical fibers are entangled with each other and the connection portion is cut.
