As shown in FIG. 2, this segment shaping jig consists of two metal fittings 20, 40 and means for forcibly widening the distance therebetween, that is, a threaded rod 34. The metal fittings 20 and 40 have almost the same shape.

初めに金具20について述べる。 First, the metal fitting 20 will be described.

In the center, the same shape and size as the cross section of segment 10,
A fan-shaped hole 22 is provided so as to pass through the front and back (the front and back are determined as indicated by arrows 23). In other words, the inner surface 24 is the outer surface 12 of the segment 10.
It is designed to fit snugly.

“FIG. 3” is a side view of the metal fitting 20 viewed from the direction of the arrow 27. The fitting 20 has tapered portions as shown at 28 and 30, which taper toward the rear. This part is inserted between the segments 10 as described below. It is tapered in this way so as not to damage the segment and so that it can be inserted deeply into the base of the conductor 10 (on the side of the cable insulator 14).

The metal fitting 20 can be divided into two vertically from the point indicated by the virtual plane 33. 35 is a connecting screw. One end of the threaded rod 34 is rotatably mounted on a bearing 32 provided on the convex portion 26 of the metal fitting 20, that is, the threaded rod 34
Even if it rotates, it remains fixed to the segment and is gripped so that it does not fall out.

Another metal fitting 40 is used for shaping the segment 10.

As mentioned above, it has almost the same shape as the metal fitting 20. That is, the cross section of the hole 42 is the same as the cross section of the segment 10, and the inner surface 44 thereof is the same as the outer surface 1 of the segment 10.
You can closely follow 2. Further, a convex portion 46 is integrally provided on the top. And it can be divided into two parts, top and bottom. Here, one of the two halves, for example, the convex portion 46, is provided with a screw hole 47 into which the threaded rod 34 is screwed, and when the screw rod 34 is rotated, the screw is fed and the metal fitting 40 moves back and forth.

なお、「第4図」のように、内面44の前端に

As shown in FIG. 4, a rounded surface 45 is provided at the front end of the inner surface 44.

Function As shown in FIG. 5, the metal fitting 20 is attached to the back of the segment 10, that is, near the cable insulator 14. Since the strand insulation film has not been removed from this area, there is no disturbance of the strands.

Note that when attaching the metal fitting 20 to the segment 10, it is tightened and fixed with the screw 35, but the metal fitting 20
The screw 35 does not necessarily have to be tightened because it is caught between the segments and cannot move back any further.

Another fitting 40 is attached to the segment 10 immediately in front of the fitting 20 and secured by tightening with a screw.

The threaded rod 34 is then turned, for example clockwise, using a suitable means, for example a handle at the tip 37.
Then, the metal fitting 40 moves forward in the direction of the arrow 36 while opposing the friction with the segment 10. Along with this, the segments 10 that are about to widen are squeezed and the strands are pushed back to their original positions, that is, into the valleys between the strands in the inner layer. As mentioned above, the front end surface 4 of the inner surface 44
5, the above-mentioned strand shaping operation is carried out smoothly. Also, it does not damage the wire at that time.

When the metal fitting 40 moves forward in the direction of arrow 36, a reaction force acts on the threaded rod 34 in the opposite direction (arrow 38). The reaction force is received by the metal fitting 20. As mentioned above, the fitting 20 is segment 1
Since it is sandwiched between zero, it can withstand the reaction force without retreating.

Note that even if the segment 10 is large in size, it can be used as long as it is spaced apart from the top and bottom in half, as shown in FIG. 6.

Effects of the Invention (1) The metal fitting 20 has a fan-shaped hole 22 with an inner surface that is in close contact with the outer surface of the cable conductor segment 10, and the outside of at least the V-shaped portion of the hole 22 has an equal wall thickness, and Since the whole is divided into two parts, by making the wall thickness appropriate (within the mechanical strength allowed), it can be easily attached to the undisturbed part of the strands at the base of the open segment 10. 10
(Do this with considerable time between each other.)

(2) 金具20、金具40間の間隔を強制的に広げ

(3) The metal fitting 40 has a fan-shaped hole 42 with an inner surface that is in close contact with the outer surface of the cable conductor segment 10, and at least the outside of the V-shaped portion of the hole 42 has an equal wall thickness, and the entire part is divided into two. Because of this shape, it can be easily attached to the segment 10 in the immediate vicinity of the metal fitting 20, and when moving forward, the wire opened during blasting returns to its original shape as described above.
