Claims (1)

[Scope of utility model registration request] A segment-type element consisting of a plurality of stranded insulated wire segments, in which the ends of the segment-type strand-insulated cable conductors are faced to each other, and a compression sleeve fitted around the outer periphery of the segment is compressed to make the connection. In a compression connection of wire insulated cable conductors, if the number of segments is even, the ends of the cable conductors facing each other are connected to the compression sleeve at the boundary surface of the segments so that they form an X circle. The segment on the removal side is cut in a range shorter than the length to form a segment end face with different levels in the longitudinal direction and an exposed segment boundary face along the longitudinal direction existing between them, and the number of segments is an odd number. The opposite ends of said cable conductor are arranged in a sector-shaped shape smaller than a circle, so that said segment on the removal side is shorter than the length of said compression sleeve at the interface of said segment closer to the inside. is cut to form segment end faces that are uneven in the longitudinal direction and exposed segment boundary surfaces along the longitudinal direction that exist between them, and the other end of the cable conductor is cut into an X circle so that it has a fan shape larger than the X circle. Each of the segments on the removal side is cut in a range shorter than the length of the compression sleeve at the boundary surface of the segment near the end surface of the compression sleeve, so that the end surface of the segment is uneven in the longitudinal direction and the exposed segment boundary surface along the longitudinal direction existing therebetween. is formed,
Each of the segment end faces is cut into a tapered surface, and the insulating coating on the outer circumferential surface of each cable conductor and the boundary surface of each segment is removed at a portion of each cable conductor that is compressed by the compression sleeve. In the cable conductor, both of the exposed segment boundary surfaces along the longitudinal direction are overlapped with each other, and the tapered segment end surfaces are abutted against each other, and the compression sleeve is fitted around the outer periphery of the overlapped butted portion. A compression connection portion of a segment type bare wire insulated cable conductor, characterized in that the conductor is compression connected.
