願平3-58368 号に示すものもある。The expansion of the insulating cylinder is carried out by inserting cylindrical expanding metal fittings having an outer diameter larger than the inner diameter of the insulating cylinder from both ends of the insulating cylinder. However, since the insulating cylinder is usually made of rubber, both expanding metal fittings are used. There was a problem that the insulating cylinder was bent due to the slight deviation of the core and the expansion metal fitting could not be inserted skillfully. There is also a jig shown in Japanese Patent Application No. 3-58368, which is a type of jig in which an expansion metal fitting is inserted from one end of an insulating cylinder.

This is a substantially U-shaped metal fitting (see FIG. 2B) for holding the insulating cylinder A with the opening 5A facing downward, and the above-mentioned three cylinders are fixed to the upper part through a mounting plate 11. When the expansion metal fitting 2 is press-fitted, the insulating cylinder A is provided with a tubular protective cover 12 which is broken into two pieces.

The sliding rod 6 is pierced through. The sliding rod 6 is the case 1
The guide groove 9 serves as a guide when the sliding plate 4 slides, and has a length substantially equal to that of the insulating cylinder A. One end of each sliding rod 6 is alternately joined to one of the sliding plates 4, and the other end is open. That is, if one end of a sliding rod is joined to the sliding plate 4R on the right side in FIG. 1 as shown in FIG. 2 (A) or (C), the other end of the sliding rod 6 adjacent thereto is The sliding plate 4L on the left side is joined, and the other sliding rods 6 are sequentially joined in the same manner. Therefore, the set fitting 5 and the cylinder 3 fixed thereto are held by the sliding plate 4 via the sliding rod 6.

The outer tube 2A has a uniform diameter over its entire length and is slightly longer than the outer tube 2A. One end is tapered and the other end is flanged.

This is one in which a pair of metal rods bent into a mold are attached to face the end surface of the inner tube 2B. In this example, as shown in FIG. 2 (A) or (C), the middle side of the metal rod is curved in an arc shape and attached concentrically with the end face of the inner pipe 2B, and the guide rod 22 is penetrated through the inner pipe 2B. It was configured so as not to become an obstacle when doing.

It is configured so that it can be connected to the connecting plate 16. The connecting plate 16 is an annular member that connects the expansion metal fitting 2 and the sliding plate 4 and is fixed to the large-diameter side end of the outer tube 2A (see FIG. 3). A groove 17 is formed on the outer peripheral surface along the entire circumference, and the groove 17 is configured to be fitted to the protrusion 10 provided on the notched end surface of the sliding plate.

When the connecting plate 16 fixed to the outer pipe 2A is viewed from the axial direction, three notches 19 are formed on the inner peripheral side as shown in FIG. 2A or 2C, and the notches 19 are It extends to groove 18. Therefore, when the inner tube 2B is fitted into the outer tube 2A, and the projection 15 provided on the flange-shaped end portion of the inner tube 2B is fitted into the notch 19 of the connecting plate 16 and appropriately rotated, the projection 15 is caught in the groove 18. , Outer tube 2A (connecting plate 15) and inner tube
2B can be joined together.

This is for penetrating into the insulating cylinder A when press-fitting the expanding metal fitting and holding the insulating material A so as not to bend from the inside thereof. In this example, the length is approximately “length of insulating cylinder + length of expanding metal fitting x 2”. I used the one from Sasa. In addition, the left and right end surfaces of the case in FIG. 1 are provided with notches (not shown) corresponding to the notches 7 of the sliding plate 4 in order to facilitate the insertion and removal of the guide rod 22.

に示すようにセット金具5の開口部5Aに装填する。[Operation] Using such a device, for example, a connecting portion of a 33 kv, 400 mm 2 , CV cable is formed. Since the outer diameter of the cable sheath is about 51 mm, the inner diameter of the insulating cylinder needs to be expanded to about 55 mm. Further, since the outer diameter of the cable insulator is 42.1 mm, an insulating cylinder having an inner diameter of 40.9 mm before expansion was used. The work procedure is as follows. First, the insulation cylinder A (eg rubber, length 370 mm, outer diameter 60
mm) is covered with a protective cover 12 that has two cracks, and this is shown in FIG.
As shown in FIG.

Is inserted to form an integral unit, and the cylinder 3 is driven to widen the gap between the sliding plates 4. Next, as shown in FIG. 4 (A), the expansion metal fittings 2 are arranged at both ends of the insulating cylinder A, respectively.
The connecting plate 16 integrated with the above is fitted into the notch 7 of the sliding plate 4.

The guide rod 22 is made to penetrate to the other enlargement metal fitting 2 through. As a result, both expansion metal fittings 2 and the insulating cylinder A are located on the same axis.

At this time, since the expansion metal fitting 2 advances along the guide rod 22, the expansion metal fitting 2 is securely press-fitted into the insulation cylinder A without causing any bending, and the insulation cylinder inner diameter is expanded.

Pull out 22 and inner tube 2B. The guide rod 22 need only be pulled out in either direction from the state shown in FIG. 4 (B), and each inner tube 2B is held by the handle 14 and slightly rotated, and the projection 15 at the flange-shaped end portion 15 is rotated.
It suffices to disengage from the groove 18 on the inner circumference of the connecting plate and pull out.

Since the inner tube 2B is longer than the inner tube 2B, the outer tube 2A is not completely press-fitted as shown in FIG. 5 (A), and there is a space between the outer tubes 2A. Therefore, as shown in FIG. 5 (B), this outer tube 2A
Are further pressed into contact with each other (enlarged diameter of insulating cylinder about 55 mm).

Next, the cable conductor is compressed or crimped by the connecting sleeve to perform the cable connecting work, and the cable connecting portion B is aligned with substantially the center of the insulating cylinder A as shown in FIG. Load the set metal fitting 5.

As shown in (A), the inner diameter of the expanded insulating cylinder A is restored to its original size, and the elastic force causes the insulating cylinder A to come into close contact with the connecting portion B. The expansion metal fitting (outer tube 2A) may be split in two and removed from the cable.

こり易い。Although the outer diameter of the insulating cylinder A and the inner diameter of the protective cover 12 are almost the same in each figure, the outer diameter of the insulating cylinder A is often smaller than the outer diameter of the insulating cylinder A. Since there is a space between the cover and the cover, the conventional method is likely to cause the insulating cylinder A to bend.

At this time, the guide rod is penetrated from one expansion metal fitting to the other expansion metal fitting to the other expansion metal fitting, the expansion metal fitting is press-fitted into the insulation cylinder, and then the guide bar is pulled out, and then the cable connecting portion is arranged in the insulation cylinder. A method for enlarging an insulating cylinder, which is characterized in that
