Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an optical cable connection test technique, and more particularly to an optical cable temporary connection reinforcing material for temporarily connecting a measuring optical cable on a measuring instrument side to an optical cable to be measured and a temporary connection method using the same.
[0002]
[Prior art]
Various methods have been proposed for connecting the optical fiber of the measurement optical cable on the measuring instrument side and the optical fiber of the optical cable to be measured when performing a connection test on the optical cable. For example, there is a connection by a heat shrinkage reinforcement sleeve, a temporary connection by an optical cable simple butter or a temporary connection method by a fusion splicer. When the number of cores of the optical cable is large, a connection method using a heat shrink reinforcement sleeve is suitable. On the other hand, when the number of cores of the optical cable is small, it is said that temporary connection using an optical cable simple butter or temporary connection using a fusion splicer is efficient.
[0003]
For example, as shown in FIG. 7 and FIG. 8, the connection method using the heat shrinkage reinforcement sleeve is preliminarily fused and fixed to the optical fibers 3 and 4 of the optical cord for measurement 1 and the optical fiber core 2 to be measured. In addition, the fusion splicing portion of the optical fibers 3 and 4 is fixed and connected by the heat shrinkage reinforcement sleeve 5.
[0004]
In this connection method using the heat shrinkage reinforcement sleeve 5, as shown in FIGS. 9A, 9B and 10C, the optical fiber 3 exposed from the measurement optical cord 1 is connected to the light to be measured. A heat shrinkage reinforcement sleeve 5 is attached to a portion of the tape core wire 2 where the optical fiber 4 is fused and connected, and the connection portion is reinforced by heat shrinkage treatment. The measuring optical cord 1 is connected to a measuring instrument 7 through a connector 6. Then, when the connection test of the optical cord 14 was completed, the optical cord 1 and the optical tape core wire 2 on both sides were cut across the heat shrinkage reinforcement sleeve 5 (the portion indicated by “x” in FIG. 9C). ). The heat-shrink reinforcing sleeve 5 was discarded together with the cut optical fibers 3 and 4.
[0005]
The temporary connection method using the optical cable simple butter is a method in which the measurement optical cord and the optical tape core to be measured are temporarily connected using the optical cable simple butter. The optical cable for measurement is fixed, and the optical cable to be measured is temporarily connected in units of optical fiber cords.
[0006]
In addition, the temporary connection method using the fusion splicer is a method in which the measurement optical cord and the optical tape core to be measured are temporarily connected by the fusion splicer. Note that it is not necessary to force connection by discharging. For example, the optical cable for measurement is fixed, and the optical cable to be measured is temporarily connected in units of optical tape cores.
[0007]
[Problems to be solved by the invention]
However, in the connection test method using the heat-shrinkage reinforcing sleeve 5, the optical cable 14 having a large number of cores is mainly used. Since the heat-shrinking reinforcing sleeve 5 is disposable, the number of cores is large. Had the problem of a large loss in work costs.
[0008]
Further, since the heat shrinkage reinforcing sleeve 5 needs to be attached to each one of the fused portions, when the number of the optical cords 1 and the optical tape cores 2 is large and there are many connection points, There was a problem that the connection work took a long time.
[0009]
The present invention has been developed to solve such problems. That is, the object of the present invention is to fix the fusion spliced portion of the optical fiber of the optical cable with a simple structure member, so that the spliced spliced portion can be easily reinforced and used repeatedly. It is to provide a temporary connection reinforcing material for an optical cable and a temporary connection method using the same.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows an embodiment of a temporary connection reinforcing material for an optical cable and a temporary connection method using the optical cable according to the present invention. FIG. 1 (a) is an explanatory side view of a state in which an optical fiber of an optical cable is sandwiched between temporary connection reinforcing materials. (B) is an explanatory side view of the state where the optical fiber of the optical cable is sandwiched between the temporary connection reinforcing materials, and (c) is an explanatory side view of the state where the optical fiber of the optical cable is sandwiched between the temporary connection reinforcing materials. FIG. 2 is a perspective view showing a state in which the fastening tool for the outer plate material of the temporary connection reinforcing material is closed.

The fastening tool 15 of this embodiment is a so-called “fitting type”, and a tongue piece member 15a is attached to the opening / closing side edge of one outer plate material 9 toward the other outer plate material 9, and the other On the edge of the outer plate member 9, a fitting convex portion 15c that can be fitted into and detached from a fitting concave portion 15b provided in the tongue piece member 15a is provided, and this tongue piece member 15a is fitted into the fitting convex portion of the other outer plate member 9. When fitted toward the portion 15c, the two outer plate materials 9 are firmly fixed. When the two outer plate members 9 are opened, the tongue piece member 15a can be easily opened by holding the tip of the tongue piece member 15a away from the fitting convex portion 15c. As for the fasteners, in addition to the fasteners 12 and 15 having the above-described configuration, it is possible to use “a configuration that is fastened with a button” or “a configuration that is secured with a string, a wire, or the like”.

[0027]
Next, the temporary connection reinforcing material 8 is pressed and fixed to the connecting portion between the optical fibers 3 and 4 to complete the reinforcement. In this state, the connection test of various optical cables 14 is performed using the measuring instrument 7. When this connection test is completed, the temporary connection reinforcing material 8 is removed, and only the connected optical fibers 3 and 4 are cut (portions indicated by “x” in FIG. 5). The temporary connection reinforcing material 8 can be reused in the next cable laying work. This eliminates the need for the heat-shrink reinforcing sleeves 5 that are conventionally attached one by one.
