を必要とし十分適しているとは言い難い。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of removing a coating on an end portion of an optical fiber core, fusion splicing an optical fiber, and re-reinforcing the spliced portion. (Prior Art) A fusion splicing method is usually used for permanent connection of optical fibers. In this method, the end coatings of the two optical fiber cores to be connected are removed by a certain length, the exposed end faces of the optical fibers are cut at right angles, and both end faces are abutted to each other to use arc discharge or the like as a heat source. It is a method of melting and connecting. After that, it is necessary to re-reinforce the above-mentioned fusion spliced portion which is not covered, but conventionally, a method of using a heat shrinkable tube as a reinforcing member as shown in FIG. 6 is generally used. In this method, as shown in FIG. 6 (a), a heat-shrinkable tube (31) is used as an outermost layer, and a hot-melt adhesive tube (32) and a steel core (33) are arranged inside the reinforcing member. As a reinforcing method, the optical fiber core wire is inserted into the hot melt adhesive tube (32) in advance before the connection, and after the connection, the reinforcing member is moved to the connection portion and heated to about 180 ° C from the outside. As shown in (b) of the figure, the heat-shrinkable tube (31) is shrunk and the hot-melt adhesive is melt-filled (32 '), and the whole is integrated around the steel core (33). As another method, as shown in FIG. 7, two flat plates (41a) (41b) each having hot melt adhesive layers (41a) (41b) adhered to opposite surfaces are used. The optical fiber (B) connection part is sandwiched and heated,
A method of melting and integrating the hot melt adhesive layers (42a) and (42b) has been proposed. (Problems to be solved) However, the method of using the heat-shrinkable tube as the reinforcing member described above has a problem in that workability is poor because the reinforcing member needs to be inserted into the optical fiber core wire in advance before connection. There is. Further, the method of using a flat plate having a hot melt adhesive layer adhered as a reinforcing member solves the above-mentioned problems, but the reinforcing member and the optical fiber are displaced during the reinforcing because the reinforcing time is long (2 to 3 minutes). There is a risk of this, and a device that simultaneously provides heating and positioning becomes large in scale, and it is poor in portability. Furthermore, since the connection work is carried out in a manhole, on a pillar, on a bridge, or in other bad conditions, it cannot be said that any of the above methods requires heating and is sufficiently suitable.

なり、接続特性のすぐれた補強部が得られる。The present invention provides a method of reinforcing an optical fiber connection portion that solves the above-mentioned problems, and is characterized by opening and closing a pair of reinforcing substrates having pressure-sensitive adhesives adhered to the opposite surfaces thereof around a fulcrum. Of the crimping tool is detachably attached to each of the upper and lower arm clamp parts, and the optical fiber connecting portion is positioned between the reinforcing substrates by the optical fiber core wire guide formed on the lower arm clamp part. Is to fix the reinforcing substrate to the optical fiber connecting portion. (Example) FIG. 1 is an explanatory view of a reinforcing tool used in the reinforcing method of the present invention, and FIG. 2 is an explanatory view of a clamp portion of the tool of FIG. As shown in FIG. 1, the reinforcing tool has upper and lower arms (1) and (2) that open and close about a fulcrum (5), and the surfaces of the tips of the upper and lower arms (1) and (2) facing each other. A clamp part (3) (4) having a groove for fitting a reinforcing member is provided on the above. By mounting the reinforcing member on the clamp part (3) (4) and grasping the gripping part (6). The upper and lower arms (1) and (2) are configured to be closed around a fulcrum and a reinforcing member is fixed and pressure-bonded to the optical fiber connecting portion. FIG. 2 (a) is an explanatory view showing a state in which reinforcing members are attached to the clamp parts (3) and (4) of the upper and lower arms (1) and (2) of FIG. The reinforcing member used in the present embodiment has two pressure-sensitive adhesives (12a) (1a) (1a) (1b) on opposite surfaces of two reinforcing substrates (11a) (11b).
Using the one to which 2b) is attached, fit into the grooves of the clamp parts (3) and (4) so that they face each other. At this time, the clamp portions (3) and (4) are provided with substrate fixing springs (7) so that the reinforcing substrates (11a) and (11b) once attached do not accidentally fall off. This spring (7) is a reinforcing substrate (11a) (11b)
It does not have to be so strong that it can be easily removed after both are integrated, and it is sufficient to support the weight of the reinforcing substrates (11a) and (11b). Also, on both sides of the lower clamp part (4), the optical fiber connection part and the reinforcing substrate (11a) (1
An optical fiber core wire guide (8) is provided to facilitate alignment with 1b). This optical fiber core wire guide (8) does not necessarily have to be the V groove, and may be constituted by a leaf spring as shown in FIGS. 2B and 2C, for example. To reinforce the optical fiber connection part, first, refer to Fig. 2 (a).
As shown in FIG. 5, the reinforcing boards (11a) (11b) are mounted on the clamp parts (3) (4) of the reinforcing tool. Subsequently, the optical fiber core wire (A) (see FIG. 4) is set on the guide (8) to align the optical fiber (B) with the reinforcing substrates (11a) and (11b). After that, grasp the gripping part (6) and clamp part (3)
When (4) is closed, as shown in FIG. 3, the end portions of the optical fiber (B) and the optical fiber core (A) are reinforced via the pressure sensitive adhesives (12a) and (12b). 11b) is fixed and crimped to form a reinforced portion. Finally, the clamp parts (3) and (4) are opened to take out the optical fiber core wire (A) together with the reinforcing substrates (11a) and (11b), but the required time is about 10 seconds. FIG. 4 is an explanatory view of another jig for further crimping the reinforcing portion by the method shown in FIG. 1 to remove the air layer and push it out. The same figure (a) is a front view and the same figure (b). FIG. 3 is a side view showing a partial cross section. The base (21) is provided with two rollers (22) (23) which rotate in the direction of the arrow in the figure, and a reinforcing portion (C) is provided between the rollers (22) and (23) from the right to the left in the figure. By moving to, the air layer remaining in the reinforcing portion (C) is removed, and the pressure bonding becomes stronger. In addition,
The lower roller (23) is provided on the space adjustment knob (24),
This makes it possible to optimally adjust the distance between the upper and lower rollers (22, 23). FIG. 5 is an explanatory view of an example in which a tension applying portion is provided for the optical fiber core wire (A) set in the optical fiber core wire guide. FIG. 5 (A) is a front view before reinforcement and (B) is reinforcement. FIG. Since the optical fiber set in the optical fiber core wire guide (8) is easily bent, the upper and lower arms (1) and (2) are closed as they are, and the optical fiber (B) is sandwiched between the upper and lower reinforcing substrates (11a) and (11b). If it is reinforced with the upper arm, the upper arm (1) may be broken or reinforced while it is bent, and the connection characteristics (coupling loss, loss variation due to heat cycle, strength, etc.) at the connection point may deteriorate.
Tension applying parts (10) are provided on both sides of the. As a result, when the upper arm (1) is lowered, tension as shown by an arrow is automatically applied to the optical fiber core wire (A) as shown in FIG. It is removed and a good reinforcement is obtained. Although the tension applying section (10) is simply attached with a member having a triangular cross section which is elastically deformed, the present invention is not limited to this. Further, when the low-strength connection portion is removed by applying this tension, it may be set appropriately, but if not, it is preferable that the tension is low enough to remove the slack of the optical fiber at most. Although the above embodiment has been described by taking the single-core optical fiber core as an example, it is needless to say that the same can be applied to a multi-core optical fiber core in which a plurality of optical fibers are integrated by a common coating. (Effects of the Invention) By using the reinforcing method of the present invention described above, the following effects are provided. A reinforcing substrate with a pressure-sensitive adhesive is used as a reinforcing member, and this reinforcing substrate is attached to the arm of a reinforcing tool,
Since the reinforcing portion is formed by closing the arm, the conventional heating is not required, and the optical fiber connection portion can be easily reinforced. Therefore, it can be easily carried out in a manhole, on a pillar, or on an overhead line where the conditions are bad. By providing the optical fiber core wire guide in the clamp portion of the arm, the optical fiber and the reinforcing substrate can be easily positioned, and the reinforcing optical fiber and the reinforcing substrate are not displaced. After forming the reinforcing portion with the reinforcing tool, the reinforcing portion is passed between two rollers whose gaps can be adjusted to remove the air layer remaining in the inside and extruding the reinforcing portion. A reinforced portion is obtained. By providing the tool with the tension applying portion of the optical fiber core wire, the tension is automatically applied to the optical fiber core wire, and the reinforcing portion having excellent connection characteristics can be obtained.
