Abstract

(57) [Abstract] [Purpose] When cutting the end aluminum wire layer to hold the steel core aluminum stranded wire, if the outer aluminum wire has a ridge for preventing icing, centering is unstable and cutting The blade may damage the inner steel core wire. On the other hand, a reliable centering is possible. [Structure] An aluminum cylinder piece P having a wall thickness equal to the height of the ridge and in which a twisted ridge can be inserted and provided with a crack p is integrally inserted into an aluminum stranded wire. If necessary, a slit k is provided on the side opposite to the split p, and an aluminum stranded wire is held by two pieces. In this state, perform centering, and then cut the aluminum stranded wire together with the aluminum cylinder piece.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 As the steel core aluminum stranded wire, one or a plurality of surface aluminum wires provided with an anti-freezing ridge is incorporated, and the present invention uses aluminum wire at the end thereof. This relates to a twisted tube piece that is added for centering when performing layer cutting work, so-called stripping work.

[0002]

[Prior art]

 When holding the steel core aluminum stranded wire, cut off the aluminum wire around the outer periphery of the end and insert the remaining steel core wire into the steel sleeve and crimp it. Japanese Patent Application No. 5-84010 is a device having a pair of upper and lower blades for cutting the aluminum wire on the outer periphery. When cutting with this type of equipment, it is strongly required to perform centering when attaching the holder so as not to damage the steel core wire. Is not easy. An appropriate inclusion is selected and inserted between the holder and the holder on the opposite side of the ridge each time, but it lacks stability during cutting and causes step defects.

[Means for solving problems]

 A twisted crack that allows the ridge to be inserted is provided in an aluminum cylinder that has a wall thickness equal to the height of the ridge and can be inserted with an aluminum stranded wire. Prepare this cylinder piece, insert it into the end of the aluminum stranded wire, and center it with this cylinder piece. Peeling with the upper and lower blades is done together with this cylinder piece.

【Example】

 The drawings will be described. Figure 1 shows the cross section of the target steel-core aluminum stranded wire. The outer circumference of the steel core wire A is surrounded by two layers of aluminum wire B, and a special wire having a ridge S is used for one aluminum wire of the outer layer.

The aluminum cylinder piece P attached to this object has an inner diameter equal to the outer diameter of the aluminum wire layer B, and the inner diameter includes the apex of the ridge S, but the crevice p into which the ridge S fits is raised. It is provided along the twist of S. (FIG. 2) This tube piece P is inserted into the end of the steel core aluminum stranded wire, and centered through the tube piece. Although a rectangular aluminum wire is illustrated in FIG. 1, the same applies to a round aluminum wire. This cylinder piece is convenient for mounting if a cut k is formed on the opposite side of the split p in the same twisting direction and divided into two pieces. If you hold the two pieces from both sides with the protrusion as the boundary, they will be attached without falling off due to twisting. In the case of an aluminum stranded wire in which two or more ridged aluminum wires are incorporated, it is obvious that the above-mentioned cut may be used as a crack in the width of the ridge S.

【effect】

 Accurate centering can be done by the attached aluminum tube piece, so that it is possible to eliminate step defects.

Claims (1)

[Scope of utility model registration request] 1. In a stripped part of an end portion of a steel-core aluminum stranded wire, in which a special aluminum wire with ridges for preventing icing is incorporated into an aluminum wire layer on the surface, the tip of the ridge is located outside the center of the stranded wire. An aluminum centering twisted tube piece that can be inserted to complement the blank part of the virtual large cylinder with the diameter.
