Description

  The present invention relates to a strand terminal processing jig and a strand terminal processing method, and in particular, a strand end processing jig for processing a strand end of each strand and a strand using the strand end processing jig And a terminal processing method.

  When the electrode terminal is joined to the end of the stranded wire, if the surface of each strand constituting the stranded wire is covered with an insulating coating, it is necessary to remove the insulating coating. As a method for removing the insulating coating of the strands, there are a method of mechanical removal using sandblast, and a method of chemical removal such as dissolution with a solvent or swelling and peeling. In order to completely remove the insulating coating on the surface of the strands by these methods, it is necessary to widen the interval between the twisted strands.

  For example, in Japanese Patent Laid-Open No. 5-336634, there is a method for removing an insulation film of a strand at a connecting end portion of a strand insulated conductor formed by twisting a plurality of strands with an insulation film into a plurality of layers by sandblasting. Proposed. In this publication, separation rings having different diameters are inserted between the twisted layers of the insulated wire conductor, and the twisted layers are separated from each other by the separation ring. An insulating film is subjected to a sand blasting process after a space capable of sand spraying is provided between the twisted layer constituting wires.

JP-A-5-336634

  However, in the method described in this publication, workability is poor because it is necessary to sequentially push a plurality of separation rings into a stranded wire from separation rings having a large diameter.

  In addition, when a plurality of separation rings having different diameters are pushed into the stranded wire, the relative position of each separation ring changes each time, so that the spread of the strands changes each time, and the quality of the stranded wire is not stable.

  Further, since the strand is twisted when the separating ring is pushed in, it is necessary to rotate the separating ring in the direction in which the strand is twisted. However, in the case of a square stranded wire, it is difficult to push in the separation ring because the corner portion of the separation ring interferes with the stranded wire and it is difficult for the separation ring to rotate.

  In addition, when an obstacle such as a part is attached to the root part where the stranded wire is extended, even if the separation ring is pushed to the end face of the obstacle, the stranded wire is within the range of the thickness of the separation ring from the end face of the obstacle. Can not spread.

  This invention is made | formed in view of the said subject, The objective is to provide the strand terminal processing jig with good workability | operativity, and the strand terminal processing method using the strand terminal processing jig. is there.

  The strand terminal processing jig of the present invention is a strand end processing jig for processing the ends of each strand of strands formed by twisting a plurality of strands, and the first surfaces intersect with each other. A step-shaped member including a step formed by the first surface and the second surface, and the end surface of the stranded wire from the oblique direction with respect to the direction in which the joint portion between the first surface and the second surface extends It is comprised so that it may contact.

  The strand terminal processing jig of the present invention is a strand end processing jig for processing the ends of each strand of strands formed by twisting a plurality of strands, and each strand is widened. A stranded wire forming member for narrowing the space between the wires, a support member for rotationally supporting the stranded wire formed member, and a stranded wire formed member supported by the support member in the radial direction of the stranded wire contacting the stranded wire formed member A slide member for guiding and a driving means for opening and closing the stranded wire forming member along the slide member, and the stranded wire forming member is formed by facing the arc-shaped outer peripheral portion and the outer peripheral portion in the thickness direction. Including.

  According to the present invention, since the end surface of the stranded wire comes into contact with the stepped shape member from an oblique direction with respect to the extending direction of the joint portion between the first surface and the second surface of the stepped shape member, the pushing operation is performed once. Thus, the end of the strand wire can be expanded into a fan shape divided into a plurality of stages, so that workability can be improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment 1)
Initially, the structure of the strand terminal processing jig of Embodiment 1 of this invention is demonstrated.

  Referring to FIG. 1, a stranded wire 1 processed by the strand end processing jig 10 of the present embodiment is formed by twisting a plurality of strands 2 together. For example, aluminum or copper is used as the material of the strand 2. Moreover, the wire diameter of the strand 2 is about 1 mm in diameter, for example. In addition, in FIG. 1, although the shape of the end surface 1a of the strand wire 1 is formed in the square shape, it is not limited to this.

  With reference to FIG. 2 and FIG. 3, the strand terminal processing jig 10 mainly includes a stepped member 3, a regulating member 4, and a guide member 5. The strand terminal processing jig 10 is an apparatus for processing the ends of the strands 2 of the stranded wire 1 formed by twisting a plurality of strands 2. In FIG. 2, each component is illustrated separately for easy viewing.

  The staircase-shaped member 3 is a member for separating the strands of the stranded wire 1 by spreading the ends of the stranded wire 1. The staircase-shaped member 3 includes a step formed by a first surface 3a and a second surface 3b that intersect each other. The staircase-shaped member 3 has an end surface 1a of the stranded wire 1 extending from a direction oblique to the direction in which the joint 3c between the first surface 3a and the second surface 3b extends (direction of arrow X in the figure). It is comprised so that it may contact.

  Specifically, the staircase-shaped member 3 has a staircase shape in which a plurality of wedge shapes having different sizes are overlapped in order of size. It should be noted that the shape of the staircase-shaped member 3 does not have to be similar to all the staircase shapes. Depending on the dimension of the stranded wire 1 and the angle at which each strand 2 (FIG. 1) is expanded, the height of each step of the staircase shape, the angle in the extending direction of the joint portion 3c, and the like may be different. Further, the staircase-shaped member 3 may be configured by being divided for each step or may be configured by one component. However, the height of each step of the staircase shape is preferably equal to or greater than one diameter of the strand 2. Further, the number of steps of the staircase shape may be changed according to the dimension of the end face 1a of the stranded wire 1.

  The guide member 5 is a member for linearly guiding the stranded wire 1 to the stepped member 3. The guide member 5 is attached to the step-shaped member 3 so as to be inclined with respect to the extending direction of the joint portion 3c. The staircase-shaped member 3 and the guide member 5 are in contact with each other without a gap.

  The regulating member 4 is a member for regulating the spread and bending of the stranded wire 1. The regulating member 4 is attached to the stepped member 3 so as to extend in a direction along one of the first surface 3a and the second surface 3b. The regulating member 4 is attached to the upper surface (the surface where the smallest wedge shape faces the regulating member 4) and the lower surface (the surface where the largest wedge shape faces the regulating member 4) of the staircase-shaped member 3. It is not limited to this. It is preferable that the regulating members 4 attached to the upper surface and the lower surface of the staircase-shaped member 3 are arranged in parallel to each other.

Next, the strand terminal processing method of this Embodiment is demonstrated.
The strand terminal processing method of the present embodiment uses the strand terminal processing jig 10 to widen the spacing between the strands 2, and to sandblast each strand 2 that has been widened. It has.

  First, the process of widening the space | interval of each strand 2 using the strand terminal processing jig | tool 10 is demonstrated. 4 to 6 are diagrams in which the regulating member 4 attached to the upper surface of the step-shaped member 3 is omitted for easy viewing.

  Referring to FIG. 4, the end of the range where the stranded wire 1 is separated is pressed by the fixing jig 6. One side surface of the stranded wire 1 is placed along the guide member 5, and the stranded wire 1 is pushed into the stepped member 3 from the end surface 1a in the direction of the arrow X in the figure. Thereby, the end surface 1a of the strand wire 1 contacts the step-shaped member 3 from a direction (arrow X direction in the drawing) oblique to the direction in which the joint portion 3c between the first surface 3a and the second surface 3b extends. .

  With reference to FIG. 5, the terminal 1b of the strand 2 of the strand wire 1 contacts the 2nd surface 3b of the step-shaped member 3, and is extended along the direction where the junction part 3c is extended. Thereby, the terminal 1b of the strand 2 of the strand wire 1 is extended in fan shape in planar view. Moreover, since the 2nd surface 3b is comprised by step shape, the terminal 1b of the strand 2 of the strand wire 1 is spread | expanded in the fan shape divided in multiple steps.

  In addition, referring to FIG. 6, an obstacle 7 such as a part may be attached to a part of the stranded wire 1. In this case, the range from the end of the end 1b of the strand 2 of the strand 1 to the end of the obstacle 7a is pushed by pushing the end surface of the strand end processing jig 10 in contact with the strand 1 to the obstacle end surface 7a. The stranded wire 1 can be expanded.

Then, the process of carrying out the sand blast process to each strand 2 with which the space | interval was expanded is demonstrated.
Referring to FIG. 29, a part of the stranded wire 1 that has been fanned out and inserted into the sandblasting device 30 is inserted. A fixing member 35 for fixing the stranded wire 1 is attached to the frame 34 of the sandblasting device 30. A spacer 36 for sealing the periphery of the stranded wire 1 is disposed inside the fixing member 35. The stranded wire 1 is supported by the sandblasting device 30 with the spacer 36 interposed.

  Sand 33 is sprayed from the injection nozzle 31 via the blast hose 32 to the terminal 1b of the strand 2 of the strand 1 that has been pushed out in a fan shape. The sand 33 is made of, for example, aluminum powder. By blowing the sand 33 onto the terminal 1b of the strand 2, the insulating coating on the end 1b of the strand 2 is removed. In the step of widening the distance between the strands 2, the strands 2 of the stranded wire 1 are fanned out to expand the gap between the strands 2, so that the sand 33 is insulated from the strands 2. The coating can be easily removed.

Next, the effect of this Embodiment is demonstrated.
According to the present embodiment, the end surface 1a of the stranded wire 1 is formed in the staircase-shaped member 3 from a direction oblique to the direction in which the joint 3c between the first surface 3a and the second surface 3b of the staircase-shaped member 3 extends. Since the terminal 1b of the strand 2 of the stranded wire 1 can be expanded in a sector shape divided into a plurality of stages by a single pushing operation, workability can be improved.

  Moreover, since the spreading method of the strand 2 of the stranded wire 1 is determined by the shape of the staircase-shaped member 3, the spreading direction of the strand 2 is constant, so that the quality of the stranded wire 1 can be stabilized.

  Moreover, since the stranded wire 1 can be expanded in a fan shape by bringing the stranded wire 1 into contact with the step-shaped member 3 from the end face 1a, even the rectangular stranded wire 1 can be expanded in a fan shape.

  Further, since the guide member 5 is attached to the step-shaped member 3 so as to be inclined with respect to the extending direction of the joint portion 3c, the side surface of the stranded wire 1 is set along the guide member 5 and the stranded wire 1 is stepped. The terminal 1b of the strand 2 of the stranded wire 1 can be expanded by linearly guiding it to the shape member 3. Since the pushing operation can be performed linearly, the operation can be simplified.

  Further, the regulating member 4 is attached to the step-shaped member 3 so as to extend in a direction along one of the first surface 3 a and the second surface 3 b of the step-shaped member 3. Thereby, when the stranded wire 1 is pushed into the strand terminal processing jig 10, the restriction member 4 restricts the spread of the stranded wire 1 in the thickness direction of the stepped member 3. By regulating the spreading direction of the stranded wire 1, the stranded wire 1 can be easily returned to its original shape after the insulating coating on the surface of the strand 2 is removed.

  Further, when an obstacle 7 such as a part is attached to the stranded wire 1, the strand 2 of the stranded wire 1 is pushed by pushing the stranded wire 1 into the strand end processing jig 10 to the obstacle end surface 7 a. The entire range from the tip of the terminal 1b to the obstacle end face 7a can be expanded.

  Moreover, since the space | interval of each strand 2 is expanded by pushing the strand wire 1 fan-shaped with the strand end processing jig 10, the sand 33 easily removes the insulating film of the strand 2 in the sandblasting process. Workability can be improved. Moreover, the quality of the strand wire 1 can be stabilized.

  Other surface treatments may be performed instead of the sandblast treatment. Chemical removal methods such as dissolving the film with a solvent or swelling and peeling the film may also be used. Mechanical force may be applied by rubbing the surface with a file or applying pressure. In addition to the surface coating, the cross-sectional shape of the strand 2 may be deformed by pressurization, or the characteristics of each strand 2 may be altered by ion irradiation or the like. Even in these methods, since the portion where the distance between the strands 2 is widened is processed, effective processing is possible.

  As shown in FIG. 7, there are two types of stranded wire 1, Z stranded wire 11 and S stranded wire 12, depending on the twist direction. Although the Z stranded wire 11 is described in the present embodiment, the S stranded wire 12 may be used. In the case of the S stranded wire 12, the extending direction of the joint portion 3 c (FIG. 4) of the step-shaped member 3 is configured to be opposite to that in the case of the Z stranded wire 11.

  Moreover, as shown in FIG. 8, in the strand terminal processing jig 10, the guide member 5 may be arrange | positioned at the bottom. In this case, the stranded wire 1 is fanned out in the height direction of the regulating member 4 in the drawing.

It is pushed into the staircase shape 3e. Thereby, the end surface 1a of the stranded wire 1 has the first stepped shape 3d and the first step 3d from the direction oblique to the direction in which the joint portion 3c between the first surface 3a and the second surface 3b extends (in the direction of arrow X in the figure).

Thereby, the terminal 1b of the strand 2 of the two strand wires 1 is each fanned out in planar view. Moreover, since the 2nd surface 3b is comprised by step shape, the terminal 1b of the strand 2 of the two strand wires 1 is each spread | expanded in the fan shape divided in multiple steps.

  As described above, according to the wire terminal processing jig 10 of the present embodiment, the same effects as those of the first embodiment are obtained.

  Further, according to the present embodiment, the first staircase shape 3d and the second staircase shape 3e are configured symmetrically with respect to the predetermined point P1 on the boundary surface J1. Thereby, since the two strands 1 can be simultaneously fan-shaped, work efficiency can be improved.

(Embodiment 3)
In the strand terminal processing jig according to the third embodiment of the present invention, the staircase-shaped member includes the first staircase shape and the second staircase shape as compared with the strand terminal processing jig according to the first embodiment. The main points are different.

  Referring to FIG. 15, the end of the range where the stranded wire 1 is separated is pressed by the fixing jig 6. The stranded wire 1 is pushed from the end surface 1a into the stepped member 3 in the direction of the arrow X in the figure so that the center point of the end surface 1a of the stranded wire 1 passes through a predetermined point P2 on the boundary surface J2. Thereby, the end surface 1a of the stranded wire 1 has the first stepped shape 3d and the first step 3d from the direction oblique to the direction in which the joint portion 3c between the first surface 3a and the second surface 3b extends (in the direction of arrow X in the figure).

  20 to 24, the stranded wire, the stranded wire forming member 21, and the support member 22 are illustrated for easy viewing, and the slide member 23, the driving unit 24, and the base member 25 are not illustrated.

  Referring to FIG. 20, the stranded wire 1 in which the strand 2 is fanned out is disposed between the movable portion 21a and the fixed portion 21b. A portion (fan-shaped portion) 26 in which the strand 2 of the stranded wire 1 is fanned out is arranged on the opposite side to the direction in which the movable portion 21a and the fixed portion 21b are pulled out. The movable portion 21a connected to the slide member 23 is slid by the driving means 24 in the arrow Y direction (the radial direction of the stranded wire 1) in the figure, and the stranded wire 1 is fixed. As the fixing position of the stranded wire 1, it is preferable to fix the root portion where the stranded wire 1 spread in a fan shape starts to be located at the closest position between the fixed portion 21b and the movable portion 21a before rotation.

  Next, in a state where the stranded wire 1 is fixed to the stranded wire forming member 21, either the stranded wire 1 or the stranded wire forming member 21 is linearly drawn and both are relatively moved.

  Referring to FIG. 21, since the stranded wire 1 is expanded in a fan shape, the fan-shaped portion 26 of the stranded wire 1 is wider than the interval between the fixed portion 21b and the movable portion 21a. Therefore, force is applied to the fixed portion 21b and the movable portion 21a in the drawing direction of the stranded wire 1 (in the direction of arrow Z in the figure). Thereby, the fixed part 21b and the movable part 21a rotate around the point where the support member 22 is rotatably supported.

  Specifically, the movable portion 21a rotates in the clockwise direction (the direction of the arrow L in the drawing) around the point where the movable member 21a is rotatably supported by the support member 22. Further, the fixing portion 21b rotates counterclockwise (in the direction of arrow R in the figure) around the point where the fixing member 21 is rotatably supported by the support member 22. At this time, the fan-shaped portion 26 of the stranded wire 1 is pushed back by the arc-shaped outer peripheral portion 21 c of the stranded wire forming member 21. Since both ends of the stranded wire forming member 21 in the thickness direction are formed with eaves portions 21d for restricting the spread of the stranded wire 1 in the thickness direction of the stranded wire forming member 21, the strand 2 is formed by stranded wire forming. The stranded wire 1 can be pushed back stably without protruding in the thickness direction of the member 21.

  Referring to FIG. 22, when the strand wire 1 further moves in the drawing direction (arrow Z direction in the figure) and moves to the end surface 1 a of the strand wire 1, the arc-shaped outer peripheral portion 21 c of the strand wire forming member 21 The stranded wire 1 spread in a fan shape is pushed back. Thereby, the strand wire 1 returns to the shape before it is fanned out.

  Moreover, with reference to FIG. 23, by adjusting the position of the movable part 21a of the stranded wire forming member 21 along the arrow Y direction (opening and closing direction of the stranded wire forming member 21) in the drawing with respect to the fixed portion 21b, A plurality of stranded wires 1 can be arranged and fixed. By pulling out the stranded wire 1 having the plurality of fan-shaped portions 26, the strands 2 of the plurality of stranded wires 1 can be simultaneously pushed back to the original shape. Note that the fixing position of the stranded wire forming member 21 may be adjusted by changing the mounting position of the fixing portion 21b.

  In addition, referring to FIG. 24, when an obstacle 7 such as a part is attached to a part of the stranded wire 1 and the stranded wire 1 is pushed up to the obstacle end surface 7 a, The obstacle end face 7a can be fixed at the closest position between the fixed portion 21b and the movable portion 21a. By pushing out either the stranded wire 1 or the stranded wire forming member 21 linearly from this state, the stranded wire 1 in the range from the obstacle end surface 7a to the end of the terminal 1b of the strand 2 of the stranded wire 1 is pushed back. Can do.

Next, the effect of this Embodiment is demonstrated.
According to this Embodiment, since it has the strand wire forming member 21 for narrowing the space | interval of each strand 2 by which the space | interval was expanded, it twists after fixing the strand wire 1 to the strand wire forming member 21. By moving either the wire 1 or the stranded wire forming member 21 linearly, the stranded wire 1 spread in a fan shape can be restored. Thereby, workability | operativity can be improved. In addition, by performing the operation of moving either the stranded wire 1 or the stranded wire forming member 21 linearly once, the stranded wire 1 spread in a fan shape can be returned to the original, so that the operation is simplified. Can do.

  Since it has the slide member 23 which guides the stranded wire forming member 21 in the radial direction of the stranded wire 1 in contact with the stranded wire forming member 21, the stranded wires 1 spread in a plurality of sectors are arranged side by side, fixed, and pulled out. Can do. Thereby, the stranded wire 1 spread in a plurality of sectors can be pushed back to the original shape at the same time.

  Since the stranded wire forming member 21 includes an arc-shaped outer peripheral portion 21c and an eaves portion 21d formed to face the outer peripheral portion 21c in the thickness direction, the stranded wire 1 is stably prevented from protruding. Can be pushed back.

  Further, when an obstacle 7 such as a part is attached to a part of the stranded wire 1 that is spread in a fan shape, the stranded wire 1 can be pushed back from the obstacle end face 7a.

First, the configuration of the wire terminal processing jig of the present embodiment will be described.
Referring to FIG. 25, the stranded wire forming member 21 further includes a roller 27 for narrowing the interval between the strands 2 whose intervals are increased. It is comprised so that the roller 27 may contact the strand wire 1 continuously with the circular-arc-shaped outer peripheral part 21c.

  The movable part 21a and the fixed part 21b each have a roller 27. Each roller 27 is disposed such that the outer peripheral surface of the roller 27 is continuous with the outer peripheral portion 21c of the movable portion 21a and the fixed portion 21b facing each other. The roller 27 is disposed in the direction of a portion (fan portion) 26 in which the strand 2 of the stranded wire 1 is fanned out. In other words, the roller 27 is a case where the arc-shaped outer peripheral portion 21c of the stranded wire forming member 21 is in contact with the stranded wire 1 when the stranded wire 1 spread in a fan shape is attached. It is arranged on the end point side of the arc.

  In addition, since the structure other than this of this Embodiment is the same as that of Embodiment 5 mentioned above, the same code | symbol is attached | subjected about the same element and the description is abbreviate | omitted.

In FIG. 26 and FIG. 27, the stranded wire, the stranded wire forming member 21, the support member 22, and the roller 27 are illustrated for easy viewing, and the slide member 23, the driving means 24, and the base member 25 are illustrated. Absent.

  Referring to FIG. 26, the movable portion 21a rotates in the clockwise direction (in the direction of arrow L in the drawing) around the point where the movable portion 21a is rotatably supported by the support member 22. Further, the fixing portion 21b rotates counterclockwise (in the direction of arrow R in the figure) around the point where the fixing member 21 is rotatably supported by the support member 22. When the fixed portion 21b and the movable portion 21a rotate to a rotatable range, the roller 27 sandwiches and holds the stranded wire 1.

  Referring to FIG. 27, when the stranded wire 1 is further moved in the drawing direction (arrow Z direction in the drawing), the movable portion 21a further rotates in the arrow L direction in the drawing, and the fixed portion 21b is further moved in the arrow R direction in the drawing. Rotate. When the movable portion 21a and the fixed portion 21b exceed the range of rotation about the point where the support member 22 is rotatably supported, the twisted wire 1 is sent back while being pushed back to the end surface 1a by the rotation of the roller 27. 1 returns to the shape before being fan-shaped.

  As described above, according to the strand terminal processing jig 20 of the present embodiment, the same effects as those of the fifth embodiment are obtained.

  Moreover, according to this Embodiment, since the strand forming member 21 is further provided with the roller 27 for narrowing the space | interval of each strand 2 by which the space | interval was expanded, the circular arc shape of the strand forming member 21 The stranded wire 1 can be pushed back over a longer distance than the outer peripheral portion 21c. Therefore, even when the range of the stranded wire 1 expanded into a fan shape is long, the stranded wire 1 can be returned to the original shape by performing the operation of pushing it back to the original shape once.
