る。(Problems to be solved by the invention) However, when the compression sleeve 6 is compressed by a compression die, as shown in FIG. 6, the compression die 4 first comes into contact with both edge portions 7 of both quad faces 5. . At this time, if the axial center positions of the compression die 4 and the compression sleeve 6 are deviated from each other, the compression die 4 comes into contact with one of the edge portions 7 of the compression sleeve 6 first, so that a rotational moment is generated and an accurate rotation occurs. In some cases, it could not be compressed into a predetermined shape. If the compression is not performed accurately, a desired conductor resistance and tensile strength of the conductor compression connection may not be obtained.

される。(Operation) The compression sleeve used in the present invention has a shape in which both edges of the quad surface of the sleeve body are chamfered so that when compressed by the compression die, the axial center positions of the compression die and the sleeve body are displaced from each other. Also, the sleeve body is accurately compressed into a predetermined shape without causing a rotational moment.
