Abstract

PROBLEM TO BE SOLVED: To make it possible to work the slot rod of an optical fiber cable without the damage of hands and coated fibers by freely attachably and detachably loading a working tool made of metal having a blade consisting of a thin metallic plate to the tip of an electric soldering iron. SOLUTION: The working tool 20 formed by mounting the blade 26 consisting of the thin metallic plate to a main body 21 made of metal is freely attachably and detachably loaded to the tip 32 of the electric soldering iron 30. The soldering iron 30 is energized to generate heat, by which the blade 26 is heated. The resin part 12 of the slot rod 10 is fusion cut by the heated blade 26. The edge 260 of the blade 26 is like a razor blade edge and, therefore, the resin part can be cut deep inside even by the small force. Since the blade 26 is stopped by screws 29, etc., the blade is easily exchangeable and the labor for removing the residual matter of the molten polyethylene is eliminated. The slot rod is cut while the rod is melted by utilizing the commercially marked soldering iron and, therefore, the rod is cuttable with the small force and there is no worry about the damage on the hand.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of processing a slot rod of an optical fiber cable, that is, a method of removing a resin portion of a main body while leaving a tension member or a mountain portion of a slot rod. Is.

[0002]

2. Description of the Related Art FIG. 3 schematically shows a slot rod 10 as a model. Generally, a tension member 14 is provided at the center of a round cord-shaped resin portion 12 made of polyethylene, and the resin portion 12 is provided with a spiral or SZ-shaped groove 120. 122 is a mountain portion.

When processing an end of an optical fiber cable, for example, as shown in FIG. 3B, the slot rod 1
It is necessary to perform processing for removing 0 to expose the tension member 14. At that time, conventionally, it was processed with a cutter such as a cutter knife.

However, there is a risk of damaging the hand or the optical fiber core by machining with a cutting tool.

[0005]

Means for Solving the Problem A processing tool 20 as illustrated in FIG. 1 is used. The processing tool 20 has a metal main body 21 to which a blade 26 made of a thin metal plate is attached. By attaching the processing tool 20 to the iron tip 32 of the electric soldering iron 30 in a detachable manner and energizing the soldering iron 30 to generate heat,
The blade 26 is heated, and the resin portion 12 of the slot rod 10 is fused by the heated blade.

DETAILED DESCRIPTION OF THE INVENTION An example of a processing tool 20 is shown in FIG. Reference numeral 21 is its main body, which is made of a metal having good thermal conductivity,
For example, it is a quadrangular prism and has a flange 22 in part. Two
Reference numeral 4 denotes a hole, which has a size in which the iron tip 32 of the soldering iron 30 is fitted exactly. It may penetrate as shown in the figure, or the tip may be closed. Reference numeral 26 denotes a blade, which is made of a thin metal having good thermal conductivity, and the blade tip 260 is sharp like a razor blade.
The blade 26 is detachably attached to the flange 22 of the main body 21 with a screw 28 or the like.

The slot rod 10 is processed as follows. As shown in FIGS. 1B and 1C, the processing tool 20 is fitted into the iron tip 32 of the soldering iron 30. When the soldering iron 30 is energized to heat the iron 32, the blade 26 is heated via the main body 21. The heated blade 26 cuts while melting the resin portion 12 of the slot rod 10 as shown in FIG.
Since the cutting edge 260 of the blade 26 is like a razor blade, it can be cut into the inside with a small force.

Since the blade 26 is fixed by a screw 28 or the like, it can be easily replaced and the labor of removing the residue of the melted polyethylene can be saved. Also, since only the blade 26 needs to be replaced,
It is cheap.

[0009]

[Other Embodiments] The processing tool 20 shown in FIG. 2 has a blade 36 bent in an L shape, and the cutting edge 36 is provided at the tip of the bent portion.
0 is formed. The blade 36 is convenient for removing the portion of the crest 122 of the slot rod 10.

[0010]

[Effects of the Invention] Since the slot rod is melted and cut by using a commercially available soldering iron, it can be cut with a small force and there is no fear of damaging the hand. Since the blade is detachable, the polyethylene attached can be removed by removing the blade. By changing the shape of the blade, it is possible to perform fine processing of the slot rod.
