Description

  The present invention relates to an electric wire covering stripping tool for removing an insulating covering material covering a core wire of an electric wire, and in particular, to an electric wire insulating covering material by an indirect hot wire method using an indirect hot wire operating tool such as an insulating Yatsuko. The present invention relates to a wire covering stripping tool for removing and exposing a core wire.

  Conventionally, when electrically connecting electric wires, the insulation covering material covering the core wires (copper wires, aluminum wires, etc.) of the wires is removed in advance to expose the core wires to be electrically connected. However, since the operation of removing the insulation coating material is complicated, a number of devices and instruments for removing the insulation coating material at the connection target position of the wires (hereinafter referred to as wire coating strippers) are provided. ing.

  And in order to ensure the safety of the worker who performs various work on the charged electric wire, the work is performed at a position where the worker is separated from the charging part by using an indirect hot wire operation tool having a longitudinal direction in one direction. The indirect hot wire method that has been performed is becoming widespread, and an electric wire covering stripping tool for such an indirect hot wire method is also provided.

  Such a wire covering stripper is configured to be attachable to the tip of an indirect live wire operating tool. For example, this type of wire covering stripper has a radius of curvature as shown in FIG. A pair of arms 61, 61 having cutting edges 60, 60 having arcuate blade portions (not shown) corresponding to the radius of the core wire Ca attached to the distal end portion, the distal end sides being able to contact and separate from each other, and each arm 61 , 61 in order to guide the electric wire C between the cutting blades 60, 60 attached to the tip of the tube 61, a cylindrical shape arranged between the pair of arms 61, 61 so that the tip of the electric wire C can be inserted. Each arm 61, 61 is configured to be connected to a pair of sandwiching bodies 80a, 80a that are provided at the distal end portion of an insulating Yachco 8a that is an indirect live line operating tool and that can be contacted and separated from each other. (Hereinafter referred to as Yatsuko's electric wire stripping tool 6) Say) there is.

  Such a wire-coating stripping tool 6 for a kitten is made to approach the cutting blades 60, 60 attached to the tips of the arms 61, 61 by operating the insulated coco 8a to bring the pair of sandwiching bodies 80a, 80a closer to each other. And the cutting blades 60, 60 that are guided by the guide portion 62 and approach each other with respect to the periphery of the insulation coating material Cb of the electric wire C between the cutting blades 60, 60 (blade portions). ing. As a result, the wire coat stripping tool 6 for Yatco configured as described above is pulled in the axial direction (tip side) of the electric wire C in a state where the tips (cutting blades 60, 60) of the arms 61, 61 are brought close to each other. It is supposed that the insulating coating material Cb on the tip side of the cuts made by the cutting blades 60, 60 can be removed from the core wire Ca.

  Further, as another wire covering stripping tool, as shown in FIG. 11, the insulating coating material Cb of the wire C is stripped by mechanically rotating the cutting blade 73 around the wire C (hereinafter referred to as “the wire covering stripping tool”). There is also a mechanical wire covering stripper 7).

  Such a mechanical wire sheath stripper 7 is provided with an operation part (not shown) on the base end side, and an indirect hot wire provided with a rotation transmitting mechanism 80b at the distal end part for outputting the operation part by rotating the operation part. This is intended for the operation tool 8b, and has a cylindrical main body 70 connected to the tip of the indirect live wire operation tool 8b, and a main body attached to the main body 70 and receiving the rotation of the rotation transmission mechanism 80b. A mechanism portion 71 that converts the rotational motion around the axis of the portion 70, a cylindrical rotational portion 72 that is connected to the mechanical portion 71 and rotates around the axis of the main body 70 by the output (rotational motion) of the mechanical portion 71; , And a cutting edge 73 projecting from the inner peripheral side of the rotating portion 72.

  The mechanical wire sheath stripping tool 7 operates the operation part of the indirect hot wire operation tool 8b with the distal end of the electric wire C inserted into the rotating part 72, so that the cutting blade 73 and the rotating part 72 are connected to the electric wire C. It is designed to rotate around. Thereby, the mechanical electric wire covering stripping tool 7 having the above configuration can rotate around the electric wire C while the cutting blade 73 is in contact with the insulating covering material Cb to strip (remove) the insulating covering material Cb. (For example, refer to Patent Document 1).

JP 2006-333632 A

  By the way, the insulation coating material Cb of the electric wire C is generally in close contact with the core wire Ca and is not easily peeled off from the core wire Ca. The YATCO wire coating stripper 6 strips off the insulation coating material Cb. In some cases, it may not be possible to remove the insulating coating material Cb, and it may take time and effort. In other words, the wire coat stripping tool 6 for Yatco is on the tip side by pulling in the axial direction (tip side) of the electric wire C in a state where the tips (cutting blades 60, 60) of the arms 61, 61 are brought close to each other. It is said that the insulation coating material Cb can be peeled off from the core wire Ca, but if the insulation coating material Cb is in close contact with the core wire Ca, the adhesion becomes resistance and the movement of the insulation coating material Cb is hindered. In some cases, the insulating coating material Cb on the tip side of the notch cannot be moved at all, or the insulating coating material Cb cannot be moved unless a large tensile force is applied.

  For this reason, there is a problem that the electric wire covering stripping tool 6 for the above configuration cannot reliably and smoothly strip the insulating coating material Cb. In particular, since the electric wire sheath stripping tool 6 attached to the tip of the insulating jacket 8a is located far from the operator, it is possible to operate the insulating jacket 8a to move the insulating coating material Cb. The fact is that the insulation coating material Cb cannot be removed smoothly.

  On the other hand, the mechanical wire sheath stripper 7 does not need to move the insulation coating material Cb unlike the wire sheath stripper 6 for Yatsuko, but the insulation sheath material Cb is surely secured by the posture and arrangement of the wire C. May not be peeled off. That is, in the mechanical electric wire sheath stripping tool 7, since the cutting edge 73 rotates concentrically with the rotating portion 72, the axial line of the electric wire C does not contact the cutting edge 73 evenly with the entire outer periphery of the electric wire C. Although it must be concentric with the rotation center of the rotating portion 72, the electric wire C is inserted into the rotating portion 72 in a curved state, or the electric wire C is inserted into the rotating portion 72 in an eccentric state with respect to the rotating portion 72. The axis of the electric wire C inserted into the rotating part 72 may not be concentric with the center of rotation of the cutting edge 73.

  Therefore, in the mechanical wire covering stripping tool 7, the insulating coating material Cb remains on the outer periphery of the core wire Ca without the cutting edge 73 coming into contact with the electric wire C (insulating coating material Cb) over the entire circumference. There is. Moreover, since the mechanical wire sheath stripping tool 7 includes a mechanism (mechanism part 71 and rotating part 72) for rotating the cutting edge 73, etc., it tends to be heavy, and the indirect hot wire operating tool 8b is used. There is also a problem that the work burden of the operator who operates becomes large.

  Therefore, in view of such circumstances, the present invention makes it possible to easily and reliably provide an insulation coating material for electric wires without increasing the work burden on the operator even if the work is performed by an indirect hot wire method using an indirect hot wire operation tool. It is an object of the present invention to provide an electric wire covering stripper that can be stripped off.

  An electric wire covering stripping tool according to the present invention is an electric wire covering stripping tool for removing an insulating covering material covering a core wire of an electric wire, and is in contact with the distal end of an indirect live wire operating tool by an operation from the base end side. A pair of divided bodies attached to each of a pair of releasable holding bodies, each of the divided bodies having a connecting portion connectable to at least one of the holding bodies and the other holding body A split body main body having a groove portion in which a half of the radial direction of the electric wire can be fitted on a surface facing the other side of the attached split body, and an arcuate blade portion whose radius of curvature corresponds to the radius of the core wire of the electric wire A first insert blade attached to the divided body with the center of curvature of the arcuate blade portion aligned with the center of the groove portion and the arcuate blade portion facing the other divided body side; A linear blade extending in the same direction as the groove from a position close to the blade A second cutting blade attached on the inner peripheral surface defining the groove portion with the linear blade portion facing the other divided body side, and projecting on the inner peripheral surface defining the groove portion of the electric wire Insulation of the electric wire between the divided bodies by the cooperation of the first insert blades of the two divided bodies by bringing the pair of divided bodies close to each other. The covering material is cut over the entire circumference, the second cutting blade cuts the insulating coating material of the electric wire in the axial direction, and the covering piercing body of each divided body is cut in the circumferential direction by cutting with the second cutting blade. It is characterized by being configured to pierce different portions of the insulating coating material divided into two or more parts.

  According to the wire covering stripping tool having the above-described configuration, the split body is attached to each of the pair of sandwiching bodies at the distal end of the indirect live wire operation tool, and the operation on the proximal end side with respect to the indirect live wire operation tool is performed. If it carries out, a pair of division body will also contact / separate mutually with a contact / separation of a pair of clamping body. And after arrange | positioning between a pair of division body so that the electric wire used as a process may be along a groove part, when this pair of division body is made to approach, between the division bodies by the 1st insert blade of both division bodies A cut extending in the circumferential direction is made in the insulating covering material of the electric wire arranged in the above, and a cutting extending in the axial direction is made in a different position of the insulating covering material by the second cutting blade of each divided body. In addition, as the pair of divided bodies approach each other, the covering and guiding body of each divided body pierces the insulating coating material of the electric wire.

  And when each divided body is kept close to each other, one half in the radial direction of the electric wire is fitted into the groove formed in the divided body main body of one divided body and formed on the divided body main body of the other divided body The other half in the radial direction of the electric wire is fitted into the groove, and the electric wire is surrounded by a pair of divided bodies (divided body main body). In this state, the electric wires fitted in the groove portions of the pair of divided bodies are annularly continuous in the circumferential direction by the cooperation of the first blades of both divided bodies with respect to the insulating coating material without cutting the core wire. And at least two cuts extending straight in the direction perpendicular to the annular cut are made by the second cutting blades of both divided bodies. As a result, the insulation coating material around the core wire is divided in the axial direction and at least in the circumferential direction, and the electric wire is divided into each of the divided regions of the insulation coating material (a plurality of regions divided by the cuts). Each of them is in a state in which the coated stab bodies of different divided bodies are stabbed.

  In this state, when the rotational force centered on the electric wire is applied to the pair of divided bodies sandwiching the electric wire by operating the indirect hot wire operation tool, each of the insulating coating materials divided in the circumferential direction by the cuts On the other hand, the rotational force acting on the divided body is transmitted. In other words, when the pair of divided bodies are brought close to each other, the coated piercing body is in a state of being pierced by the insulation coating material of the electric wire. It is transmitted to the insulating coating material through the body.

  As a result, even if the insulating coating material is in close contact with the outer periphery of the core wire, the insulating coating material is wrinkled and the insulating coating material is peeled off from the outer periphery of the core wire. Then, when the operation on the proximal end side of the indirect live wire operation tool is released, the pair of holding bodies are separated from each other, and accordingly, the pair of divided bodies attached to each holding body is also separated and the pair of divisions with respect to the electric wire is separated. The siege by the body will be released. Thereby, the insulation coating material peeled off from the core wire is removed or the insulation coating material can be removed. Since the insulating coating material is generally composed of a deformable resin molded product, it can be maintained in a state in which the covering piercing body stabs against the insulating coating material when the pair of divided bodies are separated from each other. For example, the insulating coating material of different parts divided into two or more in the circumferential direction by cutting with the second cutting blade is deformed corresponding to the separation of the divided body, and attached to the coated piercing body to be separated from the core wire. Become.

  Therefore, the electric wire covering stripping tool having the above-described configuration can easily and reliably strip the electric wire insulating covering material. In addition, the wire sheath stripping tool having the above configuration does not require a mechanism portion for transmitting rotation, and thus can be reduced in weight, and even if the work is performed by an indirect hot wire construction method using an indirect live wire operating tool. Does not increase the work burden on the worker.

  As one aspect of the present invention, each divided body has a cutting blade portion extending linearly in a direction intersecting with the extending direction of the groove portion, and at one end side in the extending direction of the groove portion with respect to the first insert blade. A wire cutting blade attached to the divided body main body with a predetermined interval is further provided, and by bringing the pair of divided bodies close to each other, the wire cutting blades of both divided bodies cooperate with each other so as to It is preferably configured to cut. If it does in this way, a cutting | disconnection of an electric wire and removal of an insulation coating material can be performed by a series of work, for example, it becomes a thing suitable for the process with respect to the high voltage underline which branches from a trunk line and is connected to a transformer.

  Specifically, when performing work on the load side (for example, transformer replacement work, etc.), the high-voltage underline that branches from the main line and is electrically connected to the transformer is cut and the downstream side from the cutting position is cut. Various work on the load side is performed after preventing the battery from being charged, and the high-voltage underlines cut after the work is completed are reconnected.

  Therefore, conventionally, when performing work on the load side, cutting work of the high-voltage underline and removal work of the insulation coating material at the tip of the high-pressure underline on the upstream side of the cutting position (stripping work of the insulation coating material) The cores of the disconnected high-voltage underline on the charging side and the high-voltage underline on the load side were individually connected to each other. However, if the wire covering stripping tool having the above configuration is used, the wire (high-voltage underline) Cutting and removal of the insulating coating material can be performed in a series of operations, and the efficiency of the operations can be improved.

  In this case, in the pair of divided bodies, the electric wire cutting blades are arranged in the middle of the groove portion, and by bringing the pair of divided bodies closer to each other, the divided body bodies of both divided bodies extend in the direction in which the groove portion extends from the electric wire cutting blade. It is preferable that the electric wire can be clamped on one end side. In this way, when the electric wire cutting blades of both divided bodies cooperate to completely cut the electric wire between the divided bodies, each of the electric wires that are divided at the cutting position is held. Can do. As a result, as described above, the cut electric wires do not drop drastically even when cutting high-voltage electric wires such as high-voltage underlines, and safety is ensured below the work position. can do.

  As another aspect of the present invention, the coated stab body may extend in the same direction as the groove and protrude in a direction different from the protruding direction of the second cutting blade. In this way, when the rotational torque around the electric wire is applied in a state where the pair of divided bodies surround the electric wire, the tip side of the covering piercing member is pierced into the insulating coating material (the reduced state) ) And the rotational torque is transmitted to the insulating coating material. As a result, the insulation coating material divided in the circumferential direction can be curled, and each insulation coating material can be reliably peeled from the core wire.

  As another aspect of the present invention, the coated impingement body may be formed in a hook shape or a hook shape with a tapered tip. In this way, the tip of the coated stab body pierces the insulating coating material, and when the rotational torque around the wire is applied while the wire is surrounded by a pair of divided bodies, The rotational torque is transmitted to the insulating coating material in a state where the impactor has pierced the insulating coating material (a reduced state). As a result, the insulation coating material divided in the circumferential direction can be curled, and each insulation coating material can be reliably peeled from the core wire. In addition, as described above, the tip end portion of the covering piercing body is formed in a bowl shape or a bowl shape, so that it is difficult to remove from the insulating coating material that has been pierced. When it is made to move, the insulating covering body moves on the covering piercing body (separated from the core wire). Therefore, the insulation coating of the electric wire can be easily removed (stripped).

  As described above, according to the wire sheath stripping tool of the present invention, even if the work is performed by the indirect live wire method using the indirect live wire operation tool, the insulation coating of the wire is performed without increasing the work burden on the operator. An excellent effect that the material can be easily and reliably peeled off can be obtained.

  The wire coating stripping tool 1 according to the present embodiment is as described above. Next, a method of using the wire coating stripping tool 1 having the above-described configuration and an operation during use will be described. Since the wire covering stripping tool 1 according to the present embodiment is provided with the wire cutting blade 24 in each of the divided bodies 2 and 2, here, in order to cut off the power supply to the load side when replacing the transformer or the like. An example will be described in which the high voltage underline C branched from the high voltage line and electrically connected to the transformer is cut, and the insulation coating of the charge side high voltage underline C (electric wire C) is removed.

  First, the pair of divided bodies 2 and 2 are attached to the sandwiching bodies 51a and 51b of the insulating jacket 5 so that the groove portions 201 face each other. Then, as shown in FIG. 6, the insulating jacket 5 is operated so that the high pressure underline C to be processed is aligned with the groove portion 201 of the pair of divided bodies 2, 2. The underline C is placed. At this time, the other end side of the base 200 (the side on which the first cutting blade 21 and the second cutting blade 22 are provided) is positioned on the high pressure line side in the high pressure drawing line C, and the one end side of the base 200 is placed on the high pressure drawing side. It is located on the transformer side in underline C.

  And the front-end | tip part of a pair of clamping body 51a, 51b is made to approach by operating the lever 52 of the insulating Yatco5. Then, as shown in FIG. 5, the divided bodies 2, 2 attached to the sandwiching bodies 51 a, 51 b approach each other, and the first insert blades 21, 21 of both divided bodies 2, 2 are between the divided bodies 2, 2. A notch extending in the circumferential direction is made in the insulating coating material Cb of the high-voltage underline C arranged in FIG. 2, and a notch extending in the axial direction at the second cutting blade 22 of each divided body 2, 2 at a different position of the insulating coating material Cb. In addition, the covering piercing bodies 23 of the divided bodies 2 and 2 pierce the insulating coating material Cb of the high-voltage underline C. That is, in the wire covering stripping tool 1 according to the present embodiment, the covering piercing bodies 23 of the divided bodies 2 and 2 are provided over the entire length in the longitudinal direction of the groove portion 201 of one groove forming member 202. Then, the covering stab body 23 is stabbed into the insulating coating material Cb of the high-voltage underline C in the region where the one groove forming member 202 exists.

  Since the wire covering stripping tool 1 according to the present embodiment is provided with the wire cutting blade 24 in each of the divided bodies 2 and 2, as described above, when the pair of divided bodies 2 and 2 approach each other, the high-voltage underline C The position is cut by the electric wire cutting blade 24 at a predetermined interval with respect to the cutting position by the first cutting blade 21.

  When the divided bodies 2 and 2 are kept close to each other, the one half in the radial direction of the high-voltage underline C is fitted into the groove 201 formed in the divided body 20 of the one divided body 2 and the other. The other half in the radial direction of the high-voltage underline C is fitted into the groove 201 formed in the divided body 20 of the divided body 2, and the high-pressure underline C is a pair of divided bodies 2 and 2 (divided bodies). The main body 20) is surrounded.

  In this state, the high-voltage underline C fitted in the groove portion 201 of the pair of divided bodies 2 and 2 is inserted into the insulating covering material Cb without cutting the core wire Ca. The blade 21 cooperates to make an annular cut continuous in the circumferential direction, and the second cut blades 22 of both divided bodies 2 and 2 make two cuts extending straight in a direction perpendicular to the annular cut. become. As a result, the high-voltage underline C is divided into two parts in the circumferential direction, with the insulating coating material Cb around the core wire Ca being divided in the axial direction, and divided into two in the circumferential direction. Each of the plurality of regions) is in a state in which the covering piercing bodies 23 of the different divided bodies 2 and 2 are pierced.

  Further, as described above, the high-voltage underline C is cut by the wire cutting blade 24, but the groove forming portion is provided without providing the second cutting blade 22 in the groove forming portion 202a of one groove forming member 202. Since the radius of curvature of the inner peripheral surface of 202a corresponds to the outer diameter of the high-pressure underline C, the cut high-voltage underline C on the load side is connected to the pair of divided bodies 2 and 2 (inner peripheral surface of the groove 201). It will be in the clamped state (see FIG. 4). Thereby, even if the high-voltage underline C is cut, the high-pressure underline C on both the upstream side and the downstream side of the cutting position is held between the divided bodies 2 and 2 (a state in which dropping after cutting is prevented). Will be maintained at.

  And in this state, if the rotational force centering on the high-voltage underline C is applied to the pair of divided bodies 2 and 2 that sandwich the high-voltage underline C by operating the insulating yoke 5, the circumferential direction is generated by the cutting. The rotational force acting on the divided bodies 2 and 2 is transmitted to each of the divided insulating coating materials Cb. That is, when the pair of divided bodies 2 and 2 are brought close to each other, the covering piercing body 23 is in a state of being pierced by the insulating coating material Cb of the high-voltage underline C. Then, the rotational torque is transmitted to the insulating coating material Cb through at least the coating stab body 23.

  Thereby, even if the insulation coating material Cb is in close contact with the outer periphery of the core wire Ca, the insulation coating material Cb is bent and the insulation coating material Cb is peeled off from the outer periphery of the core wire Ca. Then, after holding the high-voltage underline C on the load side with another insulation jacket 5, the operation of the lever 52 of the insulation jacket 5 to which the wire covering stripping tool 1 is attached (at the base end side of the indirect live wire manipulation tool 5). Is canceled. Then, after the load-side high-voltage underline C is prevented from falling off by another insulating yoke 5, the pair of sandwiching bodies 51a and 51b (the pair of divided bodies 2 and 2) are separated to form a pair with respect to the high-voltage underline C. The enclosure by the divided bodies 2 and 2 is released.

  When the divided bodies 2 and 2 are separated from each other in this manner, the covering piercing body 23 is kept in a state where it stabs against the insulating coating material Cb, and two in the circumferential direction are cut by the second cutting blade 22. Different portions of the resin insulation coating material Cb divided as described above are attached to the coating stab body 23 while being deformed corresponding to the separation of the divided bodies 2 and 2 and away from the core wire Ca.

  Then, after the load side work such as transformer replacement is completed or before the load side high voltage underline C is removed, the charge side high voltage underline C is removed after the load side work is completed. A series of operations are completed by connecting the cores Ca of the high-voltage underline C on the load side via a cylindrical compression sleeve and insulating the compression sleeve and its periphery.

  As described above, according to the wire covering stripping tool 1 according to the present embodiment, a pair of sandwiching bodies 51a provided so as to be able to come into contact with and separate from the distal end of the indirect live wire operating tool 5 by operation from the base end side. Each of the divided bodies 2 and 2 includes a connecting portion 205 that can be connected to at least one of the holding bodies 51a and 51b and the other holding body. A split body main body 20 in which a groove 201 capable of fitting a half in the radial direction of the electric wire C is formed on a surface facing the other split member 2, 2 attached to 51a, 51b, and a core wire having a radius of curvature of the electric wire C An arcuate blade portion 210 corresponding to the radius of Ca is provided, and the center of curvature of the arcuate blade portion 210 is made to coincide with the center of the groove portion 201 so that the arcuate blade portion 210 faces the other divided body 2, 2 side. Attached to the split body 20 The insert blade 21 has a straight blade portion extending in the same direction as the groove portion 201 from a position close to the first insert blade 21, and the groove portion with the straight blade portion facing the other divided body 2, 2. The second cutting blade 22 attached on the inner peripheral surface that defines 201, and the covering impact that projects from the inner peripheral surface that defines the groove 201 and can impinge on the insulating coating material Cb of the electric wire C And the pair of divided bodies 2 and 2 are brought close to each other, so that the first insert blades 21 of both the divided bodies 2 and 2 cooperate with each other in the electric wire C between the divided bodies 2 and 2. The insulation coating material Cb is cut over the entire circumference, and the second cutting blade 22 cuts the insulation coating material Cb of the electric wire C in the axial direction. So as to stab the insulating coating material Cb of different parts divided into two or more in the circumferential direction by the cutting by the cutting blade 22 Therefore, the insulation coating material Cb of the electric wire C can be easily and reliably peeled off without increasing the burden on the operator even if the work is performed by the indirect hot wire method using the indirect hot wire operation tool 5. It is possible to achieve an excellent effect of being able to.

  Further, in the present embodiment, each of the divided bodies 2, 2 has a cutting blade portion 240 that extends linearly in a direction that intersects with the extending direction of the groove portion 201, and the groove portion 201 with respect to the first insert blade 21. Is further provided with a wire cutting blade 24 attached to the divided body main body 20 at a predetermined interval on one end side in the direction in which the wires extend, and by bringing the pair of divided bodies 2 and 2 closer to each other, Since the cutting blade 24 cooperates to cut the electric wire C between the divided bodies 2 and 2, the cutting of the electric wire C and the removal of the insulating coating material Cb can be performed by a series of operations. It can be made suitable for processing the high-voltage underline C that branches off from the main line and leads to the transformer.

  In addition, the pair of divided bodies 2, 2 has the electric wire cutting blade 24 disposed in the middle of the groove 201, and the pair of divided bodies 2, 2 are brought close to each other, so that the main bodies of both the divided bodies 2, 2 are wire-cut. Since the electric wire C is clamped on one end side in the extending direction of the groove portion 201 relative to the blade 24, the electric wire cutting blades 24 of the two divided bodies 2 and 2 cooperate with each other between the divided bodies 2 and 2. When a certain electric wire C is cut, it is possible to hold the electric wire C that is divided at the cutting position. As a result, as described above, the cut electric wire C does not accidentally hang down even if the electric wire C at a high place such as the high-voltage underline C is cut, and the safety at the lower side than the working position is ensured. Sex can be secured.

  Furthermore, in this embodiment, since the said covering and thrusting body 23 is extended in the same direction as the groove part 201, and protrudes in the direction different from the protrusion direction of the 2nd cutting blade 22, it is an electric wire with a pair of division bodies 2 and 2 When a rotational torque around the electric wire C is applied in a state of surrounding C, the rotational torque is applied to the insulating coating material Cb in a state where the leading end side of the coating impingement body 23 is stuck (decreased) into the insulating coating material Cb. The insulation coating material Cb can be bent and the insulation coating material Cb can be reliably peeled from the core wire Ca.

  For example, in the above embodiment, the covering piercing body 23 is constituted by a plate, and the covering piercing body 23 is grooved along the center of curvature of the inner peripheral surface (arc surface) of the groove forming member 202 (groove forming portion 202a). Although it provided over the full length of the formation part 202a, it is not limited to this, For example, as shown in FIG.7 and FIG.8, the 1st cutting blade 21 and the 2nd cutting blade 22 are implemented above. The covering piercing body 23 is provided in the same manner as the shape, and is formed in a bowl shape or a bowl shape (in the figure, a bowl shape) that protrudes partially from the inner peripheral surface that defines the groove 201 and has a tapered tip. It may be. That is, the covering piercing body 23 may be formed in a shape having a burr while the tip end portion is tapered.

  In this case, it is preferable to provide a plurality of covering piercing bodies 23 at intervals in the axial direction of the base 200 (direction in which the groove 201 extends). If it does in this way, the front-end | tip part of the covering stab body 23 will stab into the insulation coating material Cb, and the rotational torque around this electric wire C is made to act in the state which surrounded the electric wire C with a pair of division bodies 2 and 2. The rotational torque can be reliably transmitted to the insulating coating material Cb. Thereby, the insulation coating material Cb can be bent and the insulation coating material Cb can be reliably peeled off from the core wire Ca. Further, as described above, the tip end portion of the covering piercing body 23 is made to be hook-like or hook-like so that it is difficult to come out from the insulating covering material Cb that has been pierced, and the pair of sandwiching bodies 51a and 51b are separated to form a pair of divided pieces. When the bodies 2 and 2 are separated from each other, the insulating covering material Cb moves on the covering piercing body 23 (separated from the core wire Ca). Therefore, the insulation coating material Cb of the electric wire C can be easily removed (stripped).
