  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a jig for treating a twisted wire end portion of the present invention will be described with reference to the drawings.

1 to 4 show an embodiment of a jig for treating a twisted wire end portion of the present invention.
This twisted wire end portion processing jig 1 is a tool for processing the end portion of the twisted wire W in a loop shape, and when the twisted wire W is processed in the loop shape, The clamping member 22 that fixes one side, the shaft member 21 that serves as the axis of the loop when the stranded wire W is processed in a loop shape, and is positioned between the clamping member 22 and the shaft member 21 to restrict the displacement of the stranded wire W. The jig body 2 is provided with a regulating member 23 to be mounted, and the handle 3 is rotatably attached to the shaft member 21 of the jig body 2. By rotating the handle 3, the handle 3 is rotated. The peripheral surface of the shaft member 21 is formed by pushing the stranded wire W between the shaft member 21 and the regulating member 23 to form the first bent portion W1 in the stranded wire W and rotating the handle 3 in the reverse direction. The stranded wire W is pressed along the shape to form the stranded wire W into a loop shape, and Molded member that pushes the stranded wire W between the shaft member 21 and the regulating member 23 from a direction opposite to the pushing direction when the first bent portion W1 is formed to form the second bent portion W2 in the stranded wire W. 31 is arranged.

  The jig main body 2 is configured by disposing a shaft member 21, a clamping member 22, and a regulating member 23 on a long plate-like member 20.

  The shaft member 21 is formed of a bottomed cylindrical member in which a hole portion 21a into which the shaft member 32 disposed on the handle 3 is inserted. In this embodiment, the shaft member 21 is fitted in the hole portion opened in the plate-like member 20. And fixed.

  The clamping member 22 is not particularly limited as long as the stranded wire W can be easily and detachably fixed on the jig main body 2, but in this embodiment, the stranded wire W is guided. A wall member 22B standing on the plate-like member 20 and a pressing member 22A that presses the stranded wire W against the wall member 22B and sandwiches the stranded wire W with the wall member 22B. A bolt (for example, butterfly bolt) that is screwed into a screw hole formed in a mounting member 22 </ b> C that is erected on the plate-like member 20 is configured.

The regulating member 23 is disposed between the shaft member 21 and the clamping member 22, and regulates the displacement of the stranded wire W whose position is displaced by the molding member 31 disposed on the handle 3.
In this embodiment, the regulating member 23 has a cylindrical member 23A and a head that is inserted through the cylindrical member 23A and contacts the upper end surface of the cylindrical member 23A, and is formed on the plate-like member 20 at the lower end. The mounting member 23B is provided with a male screw portion that is screwed into the screw hole.
By configuring the cylindrical member 23A and the mounting member 23B in this manner, the cylindrical member 23A can be rotated about the mounting member 23B as a rotation shaft, and the resistance of the outer peripheral surface due to the stranded wire W to be pressed. And reduce wear.

  The handle 3 includes a handle main body 30, a shaft member 32 for inserting the handle main body 30 disposed at the end of the handle main body 30 into a hole 21 a formed in the shaft member 21 of the jig tool body 2, and a handle. In order to form the stranded wire W in a loop shape or to form the first bent portion W1 and the second bent portion W2 by rotating the main body 30 about the axis of the shaft members 21 and 32 as the rotation center. The forming member 31 is formed.

  In this embodiment, the molded member 31 has the same structure as the regulating member 23, and is constituted by the cylindrical member 31A and the mounting member 31B, so that the cylindrical member 31A rotates around the mounting member 31B as a rotation axis. In a possible state, the resistance of the outer peripheral surface caused by pressing against the stranded wire W is reduced, and wear is prevented.

  In addition, the outer diameter of the shaft member 21 of the jig tool body 2, the disposition position of the restricting member 23 relative to the shaft member 21, and the disposition position of the forming member 31 relative to the shaft member 32 of the handle 3 can be changed.

The method for changing the outer diameter of the shaft member 21 of the tool body 2 can be performed by replacing the shaft member 21 with a shaft member 21 having a different outer diameter, and the inner diameter is substantially the same as the outer diameter of the shaft member 21. This can be done by attaching and detaching the cylindrical member 24.
By changing the outer diameter of the shaft member 21, the radius of curvature of the loop at the end of the stranded wire W to be processed can be easily changed.

  And when performing the change of the curvature radius of the loop of the twisted wire W to be processed or the treatment of the twisted wire W having a different wire diameter (including the case of dealing with both the change of the curvature radius of the loop and the change of the wire diameter), The arrangement positions of the regulating member 23 and the molding member 31 are changed.

  A method of changing the arrangement position of the restricting member 23 is that a plurality of screw holes (in the illustrated example, screw holes 20a) are formed on the plate-like member 20 for screwing the male screw portions formed on the mounting member 23B of the restricting member 23. And two positions of the screw holes 20b), and the mounting positions are changed according to the outer diameter of the shaft member 21 and the wire diameter of the stranded wire W.

In addition, the method of changing the arrangement position of the forming member 31 with respect to the shaft member 32 of the handle 3 is such that the handle 3 is pivotable to the shaft member 21 of the tool body 2 at both ends of the handle 3 and selectively. A shaft member 32 to be attached is disposed as a shaft member 32 ′ at one end and a shaft member 32 ″ at the other end, and the distance from the shaft member 32 is different from the distance L1 on one side and the distance L2 on the other side from the distance L1. (In the example shown in the figure, L1 <L2), so that the molding member 31 ′ is disposed at one end and the molding member 31 ″ is disposed at the other end. This can be easily performed by replacing the shaft 32 'and the shaft member 32''.
The method for changing the arrangement position of the forming member 31 may be performed by forming a plurality of screw holes in the handle body 30 in the same manner as the method for changing the arrangement position of the regulating member 23.

  Next, a procedure for processing the end of the stranded wire W (for example, an electric wire) in a loop using the stranded wire end processing jig 1 will be described.

First, as shown in FIG. 4A, the twisted wire W is clamped by the clamping member 22 of the jig tool body 2 with the end side of the twisted wire W extended toward the shaft member 21, thereby forming the handle 3. The shaft member 32 is inserted into the hole 21a of the shaft member 21 of the tool body 2 at a position where the member 31 does not contact the stranded wire W (in the illustrated example, the position where the handle body 30 is substantially perpendicular to the stranded wire W). Insert into.
In the present embodiment, processing in a state where the cylindrical member 24 is attached to the shaft member 21 is shown.

Next, as shown in FIG. 4 (b), the handle 3 is rotated counterclockwise, and the stranded wire W is pushed between the shaft member 21 and the regulating member 23 by the forming member 31 to twist the stranded wire. A first bent portion W1 is formed in W.
At this time, even if the handle 3 is rotated clockwise and the pushing (pressing force) by the molding member 31 is released, the handle 3 is pushed so that permanent distortion remains at the stress concentration portion of the first bent portion W1.

  After forming the predetermined bent portion W1, as shown in FIG. 4C, the handle 3 is rotated clockwise and the stranded wire W is pressed along the peripheral surface of the shaft member 21 by the molding member 31. The end of the stranded wire W is formed in a loop shape.

After the end portion of the stranded wire W is formed in a loop shape, as shown in FIG. 4D, the holding of the stranded wire W by the holding member 22 is released, and the handle 3 is further rotated clockwise to form the forming member. 31, the stranded wire W is pushed in from the direction opposite to the pushing direction when the first bent portion W1 is formed between the shaft member 21 and the regulating member 23, and the second bent portion W2 is inserted into the stranded wire W. Form.
The pushing (pressing force) at this time is also pushed to the extent that permanent distortion remains at the stress concentration portion of the second bent portion W2, as in the case of forming the first bent portion W1.

Thereafter, the stranded wire W is removed from the jig 1 for treating the end portion of the stranded wire, and in the state where the loop is formed at the end portion of the stranded wire W, the base portion of the loop is wound and fixed.
At this time, since the first bent portion W1 and the second bent portion W2 are formed at two locations serving as the base of the loop by the twisted wire end portion processing jig 1, the winding position of the winding wire rod Can be easily determined, and the position thereof does not vary, and the end of the stranded wire W can be uniformly and efficiently formed in a loop shape.

  As mentioned above, although the jig for twisted wire end part processing of the present invention was explained based on an example, the present invention is not limited to the composition described in the above-mentioned example, and suitably in the range which does not deviate from the meaning. The configuration can be changed.

  The jig for treating a twisted wire end portion of the present invention can form the end portion of the twisted wire in a loop shape uniformly and efficiently. It can be used for the purpose of processing.
