導体を接続するという方法がとられていた。``Prior art'' In recent years, in the electric power business, as power transmission capacity increases, the conductor diameter of power cables continues to increase in size. In other words, conductors consisting of stranded wires, in which the eastern wire that constitutes the conductor itself has an insulating skin and no current flows between the wires, can reduce the so-called skin effect, so they are being widely adopted in many fields. It has become. Also, strands of copper wire have been developed in which an insulating layer such as an enamel layer or an oxide layer is provided on the outer surface of the copper wire. When connecting copper wires, it is necessary to keep the resistance of the conductor connection part within a specified tolerance, so the conductor wires to be connected are untwisted and the insulation coating of each wire is completely coated. Once separated, the cables were inserted together into the openings at both ends of the connection sleeve, and the connection sleeve was compressed to connect both conductors.

た。[Problem 1 that ε-ro attempts to solve In the conventional technology described in 1.1, there was a problem in that when the strands were untwisted, the insulating film peeled off frequently and was troublesome. In addition, in the conventional method of connecting strands of wire, although the part of the connection sleeve that is pinched is pressed, the inner wall is relatively smooth due to the overall pressure, and the strands of wire are stretched from the sleeve. This caused undesirable conditions for the cable connection, such as the wires being pulled out, the wires being disturbed and bent within the sleeve.

し、複雑な密接面をもっていてもさしつかえない。FIG. 1 illustrates the concept of the integral embodiment of the method of the invention, Connection 2! It is a sectional view of i tool. As shown in the figure, conductors 11 and 12 consisting of two stranded insulated wires to be connected are cut to form a plane perpendicular to their axial direction, and a cylindrical connecting sleeve 2 is formed. Insert each conductor 11, 12 into the opening and press the two cut surfaces together.The insulated cable wire is made of copper, aluminum or [
A conductor 1 (11, 12) is made by twisting a large number of wires made of these alloys with an enamel layer or other thin insulating layer. Therefore, as mentioned above, it is relatively difficult to cut the stranded wire in a plane perpendicular to the longitudinal axis, and a special cutting machine must be used. It can also be obtained by cutting in advance so that the surface is relatively close to a vertical surface, and then polishing the cut surface to surface a more precise vertical surface. After inserting the conductors 11 and 12 whose cut surfaces are vertical in this manner into the openings at both ends of the connection sleeve 2, both are pushed further into the openings to press the vertical surfaces together. be. By this pressure welding, it is possible to relatively accurately bring the corresponding wires of both conductors into close contact with each other, and even if a slight deviation occurs, the corresponding cable wire and the adjacent wire l: will remain in close contact. (According to 4fi theory, the outermost strands do not come in close contact with the central strands), so problems such as skin effect do not occur when used as a power cable. As described above, the most important point in the conductor connection method of the present invention is that the cut surfaces of the two conductors inserted into the connection sleeve 2 are in close contact with point a. Therefore, the inner diameter of the connecting sleeve 12 is selected as close as possible to the outer diameter of the conductor to avoid misalignment of the cut surfaces of the conductors that are in close contact with each other, and the conductors are pressure-welded to each other to maintain perfect contact during the connection process. After pressing the cut surfaces, press both ends of the sleeve 2 to make it crimped to the conductor, or tighten compression rings fitted to both ends of the sleeve 2 to maintain the pressure contact between the conductors. It is also necessary to maintain it. It is also possible to provide R bMs for strongly gripping the conductor at both ends of the sleeve, and use the mechanisms and screws provided on the inner wall of the sleeve to press the ends of the gripped conductors by turning the mechanisms at both ends. In addition, in the embodiment shown in FIG.
The close contact surfaces between the conductor ends were formed on a plane perpendicular to the longitudinal axis of the conductors, but it is sufficient that the two conductors are in close contact with each other so that the conductors form one longitudinal axis. It is okay to have a complex, intimate aspect.

The mold jig 3 can be opened and closed in the same manner, and a support 4 is fitted in the mold jig 3 so that it can rotate and run on the mold jig 3. A press hole for the extrusion rod 5 is provided on the side of the mold jig 3. 41 is provided, and the push rod 5 is inserted into the press hole 41. It is desirable that the suppression holes 41 be arranged in two opposite directions in a plane perpendicular to the length direction of the conductor, as in the case of the press holes 31 in the mold jig 3 described above.

Next, the press rod 5 is retreated from the press hole 31, moved as indicated by the arrow in the figure to align the press hole 41 with the adjacent suppression hole 31, and the same operation is performed again. The connecting sleeve 2 and the conductor 11 are deformed, and the operation is continued to deform the conductor 12 as well. It is better to press both the pressing rods 5 at the same time. Also, connection sleeve 3
should be suppressed to a level that does not cause damage.

The support tool 4 moves on the mold jig 3. By aligning the extrusion holes on both sides and strongly pressing the pressing rod 5, the connecting sleeve 2 containing the conductor 1 is deformed. The pressing force holes in the mold jig 3 may be provided radially as described above. Although the dividing surface of the mold jig 3 is not shown in the figure (because the dividing surface is vertical and behind the pressing rod 5),
The dividing plane of the support 4 movable on the shaping jig 3 is clearly illustrated together with the fastening material, so that its attachment can be easily understood.

It is also possible to use a system in which pressing rods are arranged in all the pressing holes and all the pressing rods are pressed simultaneously and instantaneously using hydraulic equipment. In the case of the illustrated embodiment, -
Pressure can be applied by placing one pressure rod on the board and hitting the other pressure rod with a hammer, etc., and is suitable for field work where large-scale suppression equipment cannot be prepared. .

とも可能である。In the conductor connection method of the present invention, the most important point is that the cut surfaces of the two conductors inserted into the connection sleeve 2 are in close contact with each other. Therefore, the inner diameter of the connecting sleeve 2 is selected to be as close to the outer diameter of the conductor as is C: to prevent the cut surfaces of the conductors that are in close contact with each other from shifting, and to maintain perfect contact during the connection process. Use a device to press the conductors together, press both ends of the sleeve 2 to crimp it to the conductor after pressing the cut surfaces, or tighten compression rings fitted to both ends of the sleeve 2. It is also necessary to maintain the pressure contact state between the conductors. It is also possible to provide clamping mechanisms at both ends of the sleeve for strongly gripping the conductor, and use the mechanisms and screws provided on the inner wall of the sleeve to press the tips of the gripped conductors together by turning the mechanisms at both ends.

It suffices to form a transverse axis, it may have an oblique plane, or it may have a complex close contact surface.

The ends of the conductors are kept close together within the center thereof. FIG. 3 shows a cross-sectional view of a conductor connection formed in another embodiment. As shown in the figure, the conductor 1 is strongly tightened by deforming the twist arrangement as the connecting sleeve 2 deforms, and as a result, the conductor 1 and the connecting sleeve are strongly adhered, and the tip cross-section side of the conductor remains in close contact with each other. Conductors are connected.
