管等からなる補強管を示す。[Technical Background of the Invention] Conventionally, in order to connect cable conductors with a multilayer structure constructed by twisting a large number of wires, as shown in FIG. A method is used in which the conductor connection sleeve 2 is inserted into the connection sleeve 2 from both sides and abutted in the center, and then the conductor connection sleeve 2 is compressed from the outside. Note that 3 in the figure indicates a reinforcing tube made of copper tube or the like.

らなかつた。[Problems with the Background Art] However, in this method, most of the current flows through the conductor connection sleeve 2 for each layer of the cable conductor 1 at the connection part, as shown by the arrows in the figure, and the outermost layer Since the tensile strength is maintained by grasping only the wire 1a, a long conductor connecting sleeve 2 had to be used in order to lower the contact resistance and increase the tensile strength of the conductor connecting portion.

という欠点があつた。 In addition, since the gaps between the individual wires 1a cannot be sufficiently filled even by compression, the outer diameter of the conductor connection sleeve 2 cannot be sufficiently reduced even after compression, and the entire conductor connection part is large. It had the disadvantage of becoming boring.

Each wire is inserted into a wire connection sleeve having an insertion portion having a shape corresponding to the wire, and these wire connection sleeves are laminated around the outer periphery of a reinforcing tube arranged between the two cable conductors to be connected. It is characterized by the fact that it is arranged in such a way that it is compressed all at once from the outside.

導体接続部６を示す断面図である。 In the present invention, first, as shown in FIG.
The ends of the cable conductor 4, which is made by twisting a plurality of strands 4a in multiple layers, to be connected are made to face each other, and the corresponding strands 4a are connected to each other with a thin diameter element having an inner diameter approximately equal to the outer diameter of the strands 4a. The wires 4a are inserted into the wire connection sleeve 5 from both sides, and the ends of the wires 4a are butted together at the center of the wire connection sleeve 5. Next, wire 4
The cable conductor connection is achieved by arranging the wire connection sleeves 5 fitted in each case a and stacking them on the outer periphery of the reinforcing tube 7 placed between them, and compressing them all at once from the outside. part is formed. FIG. 3 is a sectional view showing the cable conductor connection portion 6 formed in this manner.

れたものとなる。 In the cable conductor connection portion 6 formed according to the present invention as described above, current flows through each strand 4a through each strand connection sleeve 5, as shown by the arrows in FIG. In addition, since the contact area between the wire connection sleeve 5 and the wire 4a is increased as a whole, the electrical and mechanical properties are excellent even if the length of each wire connection sleeve 5 is short.

Since it is buried, it is possible to obtain a compressed cable conductor connection portion that is compact and has excellent electrical and mechanical properties.
