[Prior Art] For example, in a straight connection portion of a power cable, the first
As shown in the figure, a conductor connecting pipe (sleeve) 2 is put on the ends of the cable conductors 1 and 1 to be connected, and the compressor is connected to the compressor by using a round die or a hexagonal die. A compression connection method is common. Usually, since the conductor connection pipe is longer than the compression die width and it is difficult to complete the compression connection by one compression, the compression is performed stepwise in a plurality of times.

FIG. 5 shows a conventional method of such a compression connection method. The drawing exemplifies the case of three compressions. First, the central part of the conductor connection pipe 2 is compressed by a die 3 by a predetermined amount α (compression depth required for compression connection), and then the compressed width of the compressed central part a If D is set to D, the end portions b and c of the conductor connection tube 2 are compressed by the die 3 by a predetermined amount α so as to overlap the center portion a by about D / 3 to perform compression connection.

[Problems to be Solved by the Invention] However, after the main compression of the center portion a of the conductor connection pipe 2 is performed by the die 3 for the predetermined amount α, and the end portions b and c are successively fully compressed, the compressed portion (the center portion) The connection pipe wall near the rising point p, p point portion from a) to the non-compressed portion (both end portions b, c) will fall centripetally by being compressed, and the conductor connection pipe 2 by the compression method will be dropped. In the finished state, the concave portions 21 are formed as shown in FIG. The reason that the recesses 21 and 21 are generated is considered to be that the step between the compressed portion and the non-compressed portion on the surface of the conductor connection pipe 2 is large when the central portion a is fully compressed and the both end portions b and c are fully compressed. Can be Since the presence of the recesses 21 and 21 causes a decrease in the electrical characteristics of the conductor connection portions, the surface of the conductor connection pipe 2 is cut and polished until the bottoms of the recesses 21 and 21 generated by the compression work are smoothed. And require a very cumbersome finishing operation. Also, there is a problem that the generation of cutting metal powder generated during the cutting and polishing work on the surface of the conductor connection pipe 2 has an unfavorable effect on the cable conductor connection work that dislikes the atmosphere in which dust scatters.

[Means for Solving the Problems] The gist of the present invention is to insert both ends of a conductor to be connected to a conductor connection pipe, compress the conductor connection pipe a plurality of times using a compressor and a die, and compress and connect the conductor. In this case, first, the central portion of the conductor connection pipe is temporarily compressed without being compressed by a predetermined amount, then the main portion is compressed by a predetermined amount at the end portion, and then the temporary compression portion is fully compressed. In the method of compressing and connecting the conductor.

[Operation] By temporarily compressing the central portion of the conductor connection pipe and then main-compressing the end portion, the temporary compression section is fully compressed, so that a compressed portion and an uncompressed portion (temporary compression portion) are formed on the surface of the conductor connection tube. Can be made relatively small, and accordingly, the occurrence of concave portions due to compression can be suppressed.

First, as shown in FIG. 1, the conductors 1, 1 at a pair of cable ends to be connected are exposed, and a conductor connection pipe 2 made of copper or the like is exposed.
The conductors 1 and 1 are inserted into each other and put together. Then, as shown in FIG. 2, a central portion a of the conductor connection pipe 2 is temporarily compressed using a compressor (not shown) and a die 3.

In this specification, the term “temporary compression” means that the conductors 1 and 1 are
When the compression connection is performed by using, the conductor connection pipe 2 does not reach a predetermined amount to be compressed, that is, a compression state in which the compression by the die 3 is stopped in an incomplete compression state,
The compressed state after the predetermined amount of compression is called main compression. In the present embodiment, the compression amount of the main compression, that is, the predetermined compression amount is indicated as α, and the temporary compression amount is quantitatively represented. Therefore, as an example, the temporary compression amount is simply indicated as α / 2. Therefore, the temporary compression amount =
It is not limited to α / 2.

Next, as shown in FIG. 3, both ends b and c of the conductor connection pipe 2 in the non-compressed state are placed on the center part a where the temporary compression has already been performed in the previous step by about 1/3 of the die width. The main compression is performed by overlapping and performing a predetermined amount α compression. Finally, as shown in FIG. 4, the central portion a in the temporarily compressed state is fully compressed. In this case, the level difference between the central portion a and both end portions b and c on the surface of the conductor connection pipe 2 is small because the central portion a is provisionally compressed, and a concave portion generated by compressing a large level difference portion as in the related art. Is less likely to occur. Therefore, the work of finishing the surface of the conductor connection pipe 2 after the completion of the compression connection work can be simplified.
