Description

TECHNICAL FIELD The present invention relates to an electric wire stripping tool used for stripping and removing a certain length of insulating coating in the intermediate portion of an electric wire.

When constructing power distribution facilities, bypass construction and grounding construction may be carried out in order to carry out partial power outages. At that time, in order to form a path for bypass or grounding, the insulation coating is stripped from the middle part of the wire, the conductor core is exposed, and the work of connecting the bypass device or grounding device to it is performed while the wire is still live. It is required to be implemented in

In order to meet such demands, a wire stripping tool has been developed that can spirally cut and strip the insulation coating at the middle of the wire without the operator having to directly touch the wire (for example, patented Reference 1). After the predetermined construction work is completed, restoration is achieved by attaching a plastic insulating cover to the portion where the core wire is exposed.

The wire stripping tool disclosed in Patent Document 1 is provided with a lead wire (core wire) surface scratch prevention pin that supports the core wire in order to prevent the core wire from being damaged when the insulation coating is stripped. there is

This lead wire (core wire) surface scratch prevention pin is telescopically protruding from the stripping blade-less frame side, and when the lead wire (core wire) surface scratch prevention pin is fully extended, the lead wire (core wire) surface scratch prevention pin A locking hole into which the tip of the clip is inserted is drilled in the opposite link (a link with a stripping blade).

As a result, when starting to strip the insulation coating using the wire stripping tool, the wire (wire) surface scratch prevention pin is retracted to the side without the stripping blade for the first round, so it does not interfere with the wire. After the second round, the conductor (core wire) surface scratch prevention pin extends and fits into the locking hole, so that the conductor (core wire) surface scratch prevention pin abuts and supports the core wire from which the insulation coating has been stripped. It is designed to

(Structure of wire stripping tool 100)
The wire stripping tool 100 according to the present embodiment is roughly composed of an opening/closing mechanism 110 , a rotating mechanism 200 and a stripping mechanism 300 . 1 is a perspective view showing a state in which the stripping mechanism 300 is removed from the wire stripping tool 100, and FIG. 2 is a front view showing the stripping mechanism 300. As shown in FIG.

Throughout the present specification, the conductive member inside the electric wire L is called the core wire S, and the insulating member covering the outer side of the core wire S is called the insulating coating H. Further, the entire core wire S covered with the insulating coating H is called the covered wire L or simply the wire L. As shown in FIG.

First, since the opening/closing mechanism 110 and the rotation mechanism 200 are already known, the operation of these will be briefly described. Of course, the opening/closing mechanism 110 and the rotating mechanism 200 described below are examples, and any opening/closing mechanism 110 and rotating mechanism 200 may be used as long as they can strip the insulating coating H of the electric wire L.

FIG. 3 shows the opening/closing mechanism 110 and the rotating mechanism 200 in the reference state. From this state, when the operating rod is used to rotate the operating rod connection member 125 of the opening/closing mechanism 110 in the forward direction, the rotation mechanism 200 rotates counterclockwise. When the operating rod connection member 125 of the opening/closing mechanism 110 is turned in the opposite direction, the rotating mechanism 200 rotates clockwise.

First, the operation of rotating the operating rod connection member 125 in the opposite direction until the rotation mechanism 200 is opened will be described. When the operating rod connecting member 125 is turned in the opposite direction from the state shown in FIG. When the operating rod connecting member 125 is subsequently rotated in the opposite direction, the rotation mechanism 200 rotates clockwise, and as shown in FIG. and one end of the first receiving member 210 of the rotational force receiving member 202 fixed thereto is separated from the combined second guide member 220 and second receiving member 212, and the rotating mechanism 200 and the peeling mechanism 300 It will be open. As the operating rod connecting member 125 is further rotated in the opposite direction, the degree of separation increases further and the rotating mechanism 200 is completely opened as shown in FIG. In this state, the wire L can be taken in and out from the inside of the wire stripping tool 100 .

Next, the operation of rotating the operating rod connection member 125 in the forward direction to close the rotation mechanism 200 will be described. When the operating rod connecting member 125 is rotated forward from the reference state shown in FIG. 3, the guide member 204 rotates counterclockwise in the drawing, forming an open/close lock mechanism 208 as shown in FIG. The outer surface of the outward projecting portion 228 of the lock body 222 contacts the lock body pressing member 128 projecting from the holding member 118 of the opening/closing mechanism 110 . As the operating rod connecting member 125 is further rotated in the forward direction, the hook portion 226 of the lock body 222 pushed by the lock body pressing member 128 rotates further inward (toward the center). 226 securely engages the lock body engaging member 224 .

As the operating rod connecting member 125 is further rotated in the forward direction, the rotating mechanism 200 rotates while the hook portion 226 is securely engaged with the lock body engaging member 224 as shown in FIG.

Next, the peeling mechanism 300 will be described with reference to FIGS. 2 and 8 to 13. FIG. The peeling mechanism 300 according to this embodiment generally includes a peeling mechanism main body 302 and a cutting mechanism 304 .

The skin peeling mechanism main body 302 is a substantially cylindrical member, and is configured by combining a first main body member 310 and a second main body member 312 each having an arc-shaped cross section, and is a core wire surface scratch prevention member. 400 , a support member 410 , a wire support member 420 and a wire guide 430 .

As described above, the first body member 310 has a substantially arcuate cross section, and the outer diameter of the other end is set smaller than the outer diameter of the one end. The other end portion having the smaller outer diameter is the “rotation mechanism insertion end portion 314 ” that is inserted into the central portion of the front side of the rotation mechanism 200 .

A pair of rotation mechanism attachment projections 316 are provided on the edge facing the rotation mechanism insertion end 314 on the outer surface of the first body member 310 . Further, an insertion hole insertion projection 318 protrudes from the pair of rotation mechanism mounting projections 316 along the direction in which the rotation mechanism insertion end 314 extends.

Further, a surface of the first main body member 310 facing the second main body member 312 is provided with a core wire surface scratch prevention member 400 that expands and contracts toward the second main body member 312 .

This core wire surface scratch prevention member 400 is a substantially cylindrical member and is biased in a direction extending toward the second main body member 312 . In this embodiment, a plunger is used as the core wire surface scratch prevention member 400 .

Further, as shown in FIG. 14, when the straight wire L is set in the peeling mechanism 300, the outer peripheral surface of the core wire surface scratch prevention member 400 is set so as to come into contact with the core wire S of the wire L. ing. That is, the core wire surface scratch prevention member 400 is located at a position where it interferes with the insulating coating H of the electric wire L. As shown in FIG.

As a result, when the electric wire L before being stripped is set in the stripping mechanism 300, the core wire surface scratch prevention member 400 is pushed by the insulating coating H of the electric wire L, and the first It is retracted to be received within the body member 310 .

The core wire surface scratch prevention member 400 is preferably made of a material softer than the core wire S of the electric wire L. As shown in FIG. This is because it is possible to prevent the core wire S from being damaged with a higher probability.

Moreover, it is preferable that the end shape of the core wire surface scratch prevention member 400 that abuts on the electric wire L has a corner portion 402 that abuts on the electric wire at a position closest to the cross-sectional center of the electric wire L. For example, tip shapes as shown in FIGS. 15(a) and 15(b) are conceivable.

Returning to FIGS. 2 and 8 to 13, a support member 410 is detachably attached to the first body member 310 to support the stretched core wire surface scratch prevention member 400 from the opposite side of the electric wire L. As shown in FIG.

This support member 410 has a support portion 412 that supports the core wire surface scratch prevention member 400 and a connection portion 414 that connects to the first body member 310 . In this embodiment, the support member 410 is a substantially L-shaped member, and the support portion 412 has a shape (that is, an arc-shaped concave shape) along the outer shape of the core wire surface scratch prevention member 400. .

In this embodiment shown in FIG. 10, between the tip position of the cylinder 404 on which the core wire surface scratch prevention member (plunger) 400 slides (the base of the core wire surface scratch prevention member (plunger) 400) and the support member 410 Although there is a gap X, by setting the gap X to zero, that is, by making the tip position of the cylinder 404 and the support member 410 contact each other, the extended position of the core wire surface scratch prevention member (plunger) 400 can be managed. becomes easier.

Further, a screw is formed on the outer surface of the cylinder 404 so that the core wire surface scratch prevention member (plunger) 400 and the cylinder 404 can be attached to and detached from the first body member 310 .

The second body member 312 has basically the same configuration as the first body member 310, and includes a rotation mechanism insertion end portion 314, a rotation mechanism mounting projection 316, and an insertion hole insertion projection 318. . The cutting mechanism 304 is attached to the end surface of the rotation mechanism attachment protrusion 316 of the second body member 312 opposite to the insertion hole insertion protrusion 318 .

In this embodiment, the insertion hole insertion protrusion 318 is formed in a round bar shape, and a peripheral groove 320 is formed in the tip portion thereof. Furthermore, it is preferable to chamfer the tip of the insertion hole insertion protrusion 318 in a tapered shape.

As shown in FIG. 14, the wire support member 420 is a member arranged on the opposite side of the cutting mechanism 304 from the cutting blade 330 when viewed from the core wire surface scratch prevention member 400 along the direction in which the wire L extends. It abuts on the surface of the wire L (the surface of the insulation coating H) at the start of stripping. In this embodiment, the wire support member 420 is attached to the tip surface of the first body member 310 .

By providing such a wire support member 420, the wire L is undesirably bent when the wire L is set in the wire stripping tool 100 and stripping is started. It is possible to avoid the problem that the core wire S is not exposed because it does not reach a predetermined depth, and the problem that the cutting blade 330 penetrates too deeply into the insulation coating H and damages the core wire S as well.

Returning to FIGS. 2 and 8 to 13, the wire guide 430 is a part that guides the wire L so that the wire L is set in the stripping mechanism 300 along the direction in which the core wire surface scratch prevention member 400 expands and contracts. The embodiment includes a first wire support member 432 and a second wire support member 434 . These first wire support member 432 and second wire support member 434 are preferably arranged on both sides of the core wire surface scratch prevention member 400 along the direction in which the wire L extends.

The first wire support member 432 corresponds to the side portion of the wire support member 420 described above.

The second wire support member 434 according to the present embodiment is provided at the rear end of the first main body member 310 opposite to the wire support member 420 (first wire support member 432) to prevent scratches on the surface of the core wire. Like the member 400 , it is a substantially cylindrical member facing the second body member 312 .

By providing the first wire support member 432 and the second wire support member 434 as described above, when the wire L is set in the stripping mechanism 300, the peripheral side surface of the wire L is held by the first wire support member 432 and the second wire support member. The wire L can be smoothly guided by sliding it to a predetermined position while contacting the wire 434 .

The cutting mechanism 304 is attached to the end surface of the rotation mechanism attachment protrusion 316 of the second body member 312 opposite to the insertion hole insertion protrusion 318 as described above. As the entire stripping mechanism 300 rotates around the wire L, the cutting mechanism 304 cuts and strips the insulation coating H while rotating around the wire L. As shown in FIG.

The cutting mechanism 304 according to this embodiment generally includes a cutting blade 330 , a cutting blade base member 332 , a coated chip fall prevention member 336 , a cutting blade rotation center bolt 338 , a collar 340 , and a biasing member 342 . , and retaining bolts 344 .

The cutting blade 330 is a member that cuts and strips the insulation coating H of the electric wire L. As shown in FIG. A bolt insertion hole 346 through which a cutting-blade rotation center bolt 338 is inserted is formed at substantially the center in the longitudinal direction of the cutting blade 330 according to this embodiment.

The cutting blade base member 332 is a member for holding the cutting blade 330 at a proper position with respect to the skin peeling mechanism main body 302 . The cutting tool post member 332 according to the present embodiment includes a cutting tool post member main body portion 348 formed in a substantially rectangular shape, and a base portion 350 protruding from the cutting blade post member main body portion 348 in a direction perpendicular thereto. have. The cutting blade 330 has a side surface in contact with the cutting blade base member body portion 348 and a bottom surface in contact with the base portion 350 . Also, a second bolt insertion hole (not shown) through which the cutting blade rotation center bolt 338 is inserted is formed at a position corresponding to the bolt insertion hole 346 of the cutting blade 330 in the cutting blade post member body portion 348. It is

The covering dust fall prevention member 336 is a member that has a role of preventing the covering dust of the electric wire L, which extends as the work by the electric wire stripping tool 100 progresses, from undesirably scattering or falling. The covering dust fall prevention member 336 according to this embodiment has a base portion 354 and a covering dust holding portion 356 .

The base portion 354 is a substantially plate-like member that covers the outer side of the cutting blade 330, and a third bolt insertion hole 358 through which the cutting blade rotation center bolt 338 is inserted is formed in the substantially central portion of the base portion 354.

Also, the base portion 354 is directly fixed to the second body member 312 of the skin peeling mechanism body 302 by fastening bolts 344 .

The coating scrap holding part 356 hooks and holds the insulation coating H (coating scrap) stripped off by the cutting blade 330, thereby preventing the insulation coating H from undesirably falling from the wire stripping tool 100. have. The coated dust holding portion 356 according to the present embodiment includes a strip-shaped plate-like portion 360 extending in a direction away from the cutting blade 330, and an end of the plate-like portion 360 farther from the cutting blade 330. It has a substantially constant-width strip-shaped covering scrap locking portion 362 extending in a substantially orthogonal direction. Further, the width of the plate-like portion 360 and the width of the coating scrap locking portion 362 are approximately the same size.

The cutting blade rotation center bolt 338 is a member for attaching the cutting mechanism 304 to the peeling mechanism main body 302 . The tip portion of the cutting blade rotation center bolt 338 is inserted through the third bolt insertion hole 358 in the coating chip drop prevention member 336, the collar 340, the biasing member 342, the bolt insertion hole 346 in the cutting blade 330, and the cutting blade post member 332. It is inserted in order through a second bolt insertion hole (not shown), and finally inserted and screwed into a cutting blade rotation center bolt receiving hole 364 formed in the second body member 312 of the peeling mechanism body 302 . Thus, the cutting mechanism 304 can be attached to the peeling mechanism main body 302 .

As described above, the covering dust fall prevention member 336 is fixed to the peeling mechanism main body 302 by the fastening bolt 344 at its base portion 354 . For this reason, the cutting blade 330 is rotatably held around the cutting blade rotation center bolt 338 between the coating dust fall prevention member 336 and the peeling mechanism main body 302 .

The collar 340 is a cylindrical member that provides a clearance between the cutting blade 330 and the coating dust drop prevention member 336 to secure an arrangement space for the urging member 342 that is arranged therebetween.

The biasing member 342 is a member for biasing the cutting blade 330, which is rotatably held between the coating dust drop prevention member 336 and the peeling mechanism main body 302, to rotate in a predetermined direction. , in this embodiment a coil spring is used. Of course, as long as the cutting blade 330 can be biased in a predetermined direction, it is not limited to a spiral spring.

The direction in which the biasing member 342 rotationally biases the cutting blade 330 is the direction in which the end of the cutting blade 330 that cuts the electric wire L faces the center of the electric wire L. As shown in FIG. By biasing in this way, the end of the wire L cut by the cutting blade 330 advances toward the center of the wire L as the cutting progresses, and the insulation coating H can be stripped off. When the end of the cutting blade 330 that cuts the electric wire L reaches the core wire S, the tip of the cutting blade base member main body 348 of the cutting blade base member 332 comes into contact with the core wire S or the insulation coating H. , the cutting edge 330 is prevented from advancing further and touching the core wire S.

According to the cutting mechanism 304 according to the present embodiment, by cutting the insulation coating H of the electric wire L with the cutting blade 330, the coating waste generated spirally extends to the coating waste holding portion 356, and the coating waste It winds around the plate-like portion 360 of the scrap holding portion 356 . As the insulation coating H is further cut, the coating waste reaches the coating waste retaining portion 362 of the coating waste holding portion 356 and extends beyond the coating waste holding portion 356 .

When the covering chips extend beyond the covering chips locking portion 362 in this way, the covering chips are always engaged with the coating chips locking portion 362 at a part thereof. Therefore, when the coating scraps are separated from the wire L during the work of stripping the insulation coating H or at the end of the work, the coating scraps do not undesirably leave the wire stripping tool 100 .

(Operation of the wire stripping tool 100 according to the embodiment)
Next, the operation of the wire stripping tool 100 described above will be briefly described. Since the opening/closing mechanism 110 and the rotating mechanism 200 rotate as described above, when the peeling mechanism 300 is attached to the rotating mechanism 200 and the operating rod connection member 125 is rotated in the opposite direction, the rotating mechanism 200 and the peeling mechanism 300 are rotated. It will be open.

In this state, the electric wire L is set in the stripping mechanism 300, and then the operation rod connecting member 125 is rotated in the forward direction. As shown in FIG. Become.

As the operating rod connecting member 125 is further rotated in the forward direction from this state, the stripping operation of the wire L by the stripping mechanism 300 progresses.

(Characteristics of the wire stripping tool 100 according to the embodiment)
According to the wire stripping tool 100 according to the above-described embodiment, the first body member 310 constituting the stripping mechanism body 302 is provided with the core wire surface scratch prevention member 400 that expands and contracts toward the second body member 312. A support member 410 that supports the core wire surface scratch prevention member 400 from the opposite side of the electric wire L has a connection portion 414 that connects to the first body member 310 .

Thus, the core wire surface scratch preventing member 400 in the wire stripping tool 100 according to the present embodiment is provided with the core wire surface scratch preventing member 400 by the support member 410 connected to the same first main body member 310 where the core wire surface scratch preventing member 400 is provided. Since it is supported, even if it is pushed by the core wire S or the like while the core wire surface scratch preventing member 400 is expanding and contracting, the supporting member 410 continues to hold the stretching direction of the core wire surface scratch preventing member 400. It is possible to provide the wire stripping tool 100 that can avoid damage to the core wire surface scratch prevention member 400 .

Further, the peeling mechanism main body 302 is provided with a wire support member 420 disposed on the side opposite to the cutting blade 330 in the cutting mechanism 304 when viewed from the core wire surface scratch prevention member 400 along the direction in which the wire L extends. there is

By providing such a wire support member 420, the wire L is undesirably bent when the wire L is set in the wire stripping tool 100 and stripping is started. It is possible to avoid the problem that the core wire S is not exposed because it does not reach a predetermined depth, and the problem that the cutting blade 330 penetrates too deeply into the insulation coating H and damages the core wire S as well.

Further, the stripping mechanism main body 302 is provided with a wire guide 430 that guides the wire L so that the wire L is set in the stripping mechanism 300 along the stretching direction of the core wire surface scratch prevention member 400 .

As a result, when the wire L is set in the stripping mechanism 300, the extension and contraction of the core wire surface scratch prevention member 400 and the guide of the wire L can be performed smoothly.

Further, the end shape of the core wire surface scratch prevention member 400 that abuts on the electric wire L has a corner portion 402 that abuts on the electric wire L at a position closest to the cross-sectional center of the electric wire L. As shown in FIG.

As a result, when the electric wire L is set in the stripping mechanism 300, the tip of the core wire surface scratch preventing member 400 pushed by the electric wire L can be bent away from the stretching direction of the core wire surface scratch preventing member 400, thereby minimizing the force. When the electric wire L is set in the stripping mechanism 300, the extension and contraction of the core wire surface scratch prevention member 400 and the guide of the electric wire L can be performed smoothly.

In addition, since the support portion 412 of the support member 410 has a shape that conforms to the outer shape of the core wire surface scratch prevention member 400, the support member 410 does not damage the surface of the core wire surface scratch prevention member 400, and the surface of the core wire surface scratch prevention member 400 is more reliably The core wire surface scratch prevention member 400 can be supported.

Further, by forming the core wire surface scratch prevention member 400 with a material softer than the core wire S of the electric wire L, the core wire S can be prevented from being damaged with a higher probability.

It should be considered that the embodiments disclosed this time are illustrative in all respects and not restrictive. The scope of the present invention is indicated by the scope of the claims rather than the above description, and is intended to include all modifications within the scope and meaning equivalent to the scope of the claims.
