Abstract

PURPOSE:To attain connection having connecting strength and to replace an optical fiber cable without damaging the inside of an aluminum pipe by roughing the connection end of a lead wire, winding a bind wire such as stainless wire around the connection end and soldering the wound part. CONSTITUTION:The lead wire 9 consists of a fluororesin coat 11a and a piano wire 10a (a high-tensile-strength wire) and formed by peeling the coat 11a, exposing the piano wire 10a, roughing the surface from its end part by a sand paper, winding a stainless bind wire 13 around the roughed part, soldering 14 the wound part, and then cutting off projections by a file. On the other hand, the surface of the connection end of an FRP coat 8 of an FRP coated optical cable 1 is cut off by a sand paper to reduce the outer diameter, the inner optical cable is removed and longitudinal slits 15 are formed on four approximately uniformly dispersed positions. Then, an FRP coated piano wire (the piano wire exposed from the lead wire 9) is inserted into the end part of the cable 1, a bonding agent is injected from the FRP coated slit 15, a polyester or nylon string 16 is tightly wound from the external and then the cable 1 is left as it is until the bonding agent is set.

At this time, the heat-shrinkable plastic sleeve 17t is inserted into one side of the cable field ≧ the lead wire (in the figure, the heat-shrinkable plastic sleeve 17 is inserted into the lead wire as shown in FIG. 1 (E)). Pull it back and heat shrink it to cover the connection part to complete the connection.The outside diameter of this connection part is 3.
At 0φwam, the load capacity is 152 to 160 mm f'C (Reference FRP 300 mm, lead wire 160 mm, and polyester thread L Oklf have sufficient strength 'kN.) Other examples of the present invention Instead of the densely wound polyester thread or nylon thread 16, 0.2φm @ stainless steel thread is used.
If the T-bind wire is used, the stainless steel wire will not break due to friction even if the aluminum pipe circle is pulled, so there is no need to cover it with a heat shrink sleeve. The outer diameter of the connecting part is 2.8

(Effects of the Invention) In the present invention, the connecting end of the lead wire is of course roughened and wrapped around a bind wire made of stainless steel or the like and soldered, so this bind wire part serves as an anchor and covers the FFLPm. It becomes a strong bond.

Even if both sides are pulled, they will not slip off, and even if the surface of the end of the FRP coating is scraped to reduce the cross-sectional area, the F-PO strength is extremely high, and the original cross-section If it is 60% or more of the area, it will be smaller than the strength of the lead wire.

In the present invention, a binding 16 as shown in FIG.
This can be done using an appropriate material such as polyester thread, nylon thread, stainless steel wire, etc., but if you leave it until the adhesive is completely dry, you only need to bind it in one place, and if the adhesive is not completely dry, If you are going to implement it, it is better to bind it in three places.

Next, when replacing the original FRP-coated fiber cable, about 100011E will be moved inside the aluminum pipe, so if there is no heat-shrinkable plastic sleeve as mentioned above, polyester thread or nylon thread will be used. Although there is a risk that the tube will wear out and break, it is preferable to use a heat-shrinkable tube because it has excellent abrasion resistance and has a small coefficient of friction, so the pulling force is small and the tube is sufficiently protected.

As the material for the heat-shrinkable sleeve, a fluororesin is preferable in consideration of heat resistance, coefficient of friction, etc.

Also, the length t of the connection part between the FRP coating and the high tensile strength wire is 35
~40m1K is preferable, and if L<35tnm, the soldering area will be too small and the load capacity will be too small.
When the length of the connection part is 45 mm, the load capacity will not change even if the length t of the connection part is made longer than this. Since the connection part has poor flexibility, there is a risk of rubbing and damaging the circular surface of the aluminum pipe when it passes through the circular surface of the small diameter aluminum pipe. Furthermore, since the optical composite overhead ground wire has curved portions of different sizes, the resistance increases if the connection portion is long.

大きな引き抜き力を必要とするので好ましくない。This is not preferable because it requires a large pulling force.
