Description

Coated wire stripper

Technical Field

The invention relates to a covered wire stripper. The covered wire is, for example, an insulated wire distributed in the air (in other words, an insulated wire for overhead power distribution wire). Examples of the insulated wires include Ethylene insulated wires, polyethylene insulated wires, EP (Ethylene Propylene) rubber insulated wires (Ethylene Propylene rubber insulated wires), and crosslinked polyethylene insulated wires for high voltage reduction (PDC: a plate transducer driver wire crosslinked polyethylene insulated wire, hereinafter sometimes referred to as PD wire).

Background

When performing construction using a PD wire or the like, a covered wire stripper is known which peels off a covering layer of the PD wire or the like.

For example, patent document 1 (japanese patent application laid-open No. 10-215512) describes a coating stripper. The coating stripper described in patent document 1 includes a pair of wire clamping bodies for clamping the coating wire. When the pair of thread clamping bodies are in the closed position, threads are formed on the inner surfaces of the pair of thread clamping bodies. A blade configured to bite into the covered wire is provided on an inner surface of the wire clamping body. When the pair of wire clamping bodies are rotated around the covered wire in a state where the pair of wire clamping bodies are in the closed position, the covering material of the covered wire is continuously peeled off from the electric wire. The peeled coating material is discharged from the discharge hole toward the side of the clip body.

Patent document 2 (jp 2009-. The covered wire peeling device described in patent document 2 includes: a coating peeling tool; a rotary drive tool; and a coating peeling tool holding section for mounting the coating peeling tool to the rotary driving tool. The covered wire stripping device comprises: the wire peeling device includes a pair of holding members formed with wire holding portions, and a peeling blade that protrudes toward a covered wire held in the wire holding portions and peels off an insulating cover. When the covered wire stripping device is operated, a remote operation rod of a rotary driving tool is rotated around a long axis of the remote operation rod. As a result, the rotational force applied to the remote operation rod is transmitted to the coating peeling tool via the rotation transmission portion, and the coating peeling tool rotates around the coated electric wire. By this rotation, the peeling blade rotates relative to the covered electric wire, and the insulating coating of the covered electric wire is peeled off by the peeling blade.

Patent document 3 (japanese patent application laid-open No. 2006-251260) describes a steel strip stripping tool for an optical cable. The steel strip stripping tool described in patent document 3 is a tool for stripping a steel strip from an optical cable having a core portion and a steel strip wound around the outer periphery of the core portion. The steel strip stripping tool is provided with a pair of holding blocks capable of contact/separation operation. Holding grooves for holding the optical fiber with the coating layer stripped are formed on the opposite surfaces of the pair of holding blocks. Further, a knife is formed on one of the pair of holding pieces, and the tip of the knife bites into the joint of the steel strip.

Detailed Description

Hereinafter, a covered wire stripper according to an embodiment will be described with reference to the drawings. In the present specification, the same or similar reference numerals are attached to members having the same functions. Note that, the same or similar reference numerals are attached to members, and a repetitive description thereof may be omitted.

(first embodiment)

A covered wire stripper 4 according to a first embodiment will be described with reference to fig. 1 to 5. Fig. 1, 2, and 5 are schematic front views showing an example of the covered wire stripper 4 according to the first embodiment. Fig. 1 and 5 show a case where the peeler body 5 of the covered wire peeler 4 is in a closed state, and fig. 2 shows a case where the peeler body 5 is in an open state. Fig. 3 is a schematic side view showing an example of the covered wire stripper 4 according to the first embodiment. Fig. 4 is a schematic side view showing an example of the guide body 8 of the covered wire stripper 4 according to the first embodiment.

Refer to fig. 1 and 2. The covered wire stripper 4 includes a stripper body 5, a cutter body 7, and a guide body 8. The covered wire stripper 4 may also include an operating mechanism 6.

(body of peeler)

The peeler body 5 includes a first member 51 and a second member 52. The first member 51 is relatively movable with respect to the second member 52. The first member 51 has a first groove 55 formed therein. The second member 52 has a second groove 56 formed therein. When the peeler body 5 is in a locked state, that is, when the first member 51 and the second member 52 are in contact with or close to each other, the peeler body 5 can hold the covered wire 1. More specifically, when the dehider body 5 is in the locked state, the covered wire 1 is held in the space formed by the first groove 55 and the second groove 56. In other words, when the dehider body 5 is in the locked state, the first groove 55 and the second groove 56 cooperate to form the covered wire accommodating space 50 (see fig. 1) that accommodates a part of the covered wire 1. As shown in fig. 3, the covered wire housing space 50 is provided so as to penetrate the peeler body 5 from one end of the peeler body 5 to the other end. Therefore, the covered wire stripper 4 in the first embodiment can strip the covering layer at the central portion in the longitudinal direction of the covered wire. The wire exposed by the peeling of the coating layer is connected to, for example, another wire.

As shown in fig. 3 and the like, the direction in which the first groove 55 extends is defined as "first direction" in this specification. Also, a direction in which the first member 51 is separated from the second member 52 is defined as a "second direction". The second direction is perpendicular with respect to the first direction. Further, a direction perpendicular to both the first direction and the second direction is defined as a "third direction".

The peeler body 5 is changeable between a locked state (see fig. 1) in which the covered wire can be held and an open state (see fig. 2) in which the covered wire can be received and removed. More specifically, by enabling the first member 51 to move relative to the second member 52 in the second direction, the state of the dehider body 5 can be changed between the locked state and the open state. In the open state shown in fig. 2, the dehider body 5 can receive the covered wire 1 by moving the covered wire 1 in the third direction. In the opened state shown in fig. 2, the covered wire 1 can be taken out from the peeler body 5 by moving the covered wire 1 in the direction opposite to the third direction.

In the example illustrated in fig. 1 and 2, the first member 51 is moved relative to the second member 52 by directly operating the operating portion 61 of the operating mechanism 6 provided in the dehider body 5, or indirectly operating the operating portion via a remote operating bar separate from the dehider body 5.

When the peeler body 5 includes the operation mechanism 6, the operation mechanism 6 may include, for example: a screw portion 610 screwed into the female screw portion 510 of the first member 51; and a reverse screw part 620 screwed into the female screw part 520 of the second member 52. In this case, the first member 51 can be moved in a direction relatively close to the second member 52 by rotating the operation portion 61 in the first rotational direction about the direction along the second direction as the center axis. Then, by rotating the operation portion 61 in the direction opposite to the first rotation direction, the first member 51 can be moved in a direction away from the second member 52. The mechanism for moving the first member 51 relative to the second member 52 is not limited to the mechanism shown in fig. 1 and 2. For example, the mechanisms disclosed in paragraphs 0017 and 0018 of patent document 3 can be adopted.

In the example shown in fig. 1 and 2, the peeler body 5 is provided with a guide rod 63 extending through the first member 51 and the second member 52. The guide bar 63 functions to prevent the first member 51 from rotating relative to the second member 52. The guide bar 63 may be omitted, or may be replaced with another rotation preventing mechanism.

(cutter body)

The blade 7 is attached to the first member 51 of the dehider body 5 by any attachment mechanism such as a screw (e.g., see the screw 11 shown in fig. 3). The blade 7 has a blade 71 for separating the coated wire 1 into the coating layer 2 and the wire 3. As shown in fig. 1, the bit 71 of the blade body 7 protrudes into the covered wire accommodating space 50. The chip 71 bites into the coating layer 2 along the circumferential direction (tangential direction) of the wire 3. As a result, coating layer 2 is separated from wire 3. In the example shown in fig. 1, the peeler body 5 is rotated (rotated in the direction of R1) about the covered wire 1 accommodated in the covered wire accommodating space 50, whereby the blade 71 bites into the covering layer 2.

In the example shown in fig. 1, coating layer 2 separated from wire 3 moves along a path indicated by arrow F. In the first embodiment, a member that guides coating layer 2 separated from wire 3 to be discharged along a path indicated by arrow F is used as guide 8.

(guide body 8)

The guide 8 is attached to the first member 51 of the dehider body 5 by any attachment mechanism such as a screw 12. The guide 8 has a guide hole 80 capable of guiding the coating layer 2 separated from the wire 3. In the first embodiment, the shape of the guide hole 80 is arbitrary. Fig. 4 (a side view of the guide body 8) shows an example of the guide hole 80.

The guide 8 guides the coating layer 2 discharged from the peeler body 5 toward the outside of the guide 8. In the first embodiment, since the covered wire stripper 4 includes the guide 8, the movement of the covering layer 2 discharged from the stripper main body 5 in an irregular direction (movement in an unintended direction) is suppressed. As a result, the coating layer 2 is prevented from being entangled with the peeler body 5 and the like. Moreover, in the first embodiment, even in the case where the coating layer 2 separated from the wire rod 3 has been completely cut off from the coated wire 1, since a part of the coating layer 2 is located between the guide body 8 and the peeler body 5 (in other words, a part of the coating layer 2 is sandwiched between the guide body 8 and the peeler body 5), an effect of suppressing the falling of the coating layer 2 is achieved.

Next, the arrangement of the guide 8 for more effectively suppressing the falling of the coating layer 2 will be described with reference to fig. 5.

(first Condition regarding configuration of guide body)

The first condition regarding the arrangement of the guide body is a condition that the bit 71 of the cutter body 7 and the guide hole 80 do not overlap each other when the dehider body 5 is viewed in the third direction. In the case where the tool bit 71 and the guide hole 80 overlap each other in the third direction, there are cases where: coating layer 2 separated by cutting tip 71 is discharged without coming into contact with the first direction end of guide hole 80. Therefore, when the coating layer 2 has been completely cut off from the coated wire 1, there are cases where: the coating layer 2 falls without being held by the guide 8 and the peeler body 5. On the other hand, when the first condition is satisfied, a part of coating layer 2 separated by cutting tip 71 comes into contact with the first direction end of guide hole 80, and a frictional force is likely to be generated. As a result, even when coating layer 2 has been completely cut off from coated wire 1, a part of coating layer 2 is held between guide 8 and peeler body 5. In this way, the risk of dropping coating layer 2 is reduced.

(second Condition regarding configuration of guide body)

Referring to fig. 3 and 5, the following is assumed: when the dehider body is in the closed state, the first recess 571 formed in the first member 51 and the second recess 572 formed in the second member are configured to cooperate to form the coating discharge hole 57. In this case, the second condition regarding the arrangement of the guide body is a condition that the coating layer discharge hole 57 and the guide hole 80 do not overlap each other when the peeler body 5 is viewed in the third direction. When the second condition is satisfied, a part of coating layer 2 separated by cutting tip 71 is also in contact with the first direction end of guide hole 80, and friction force is likely to be generated. As a result, even when the coating layer 2 is completely cut off from the coated wire 1, a part of the coating layer 2 is held between the guide 8 and the peeler body 5. In this way, the risk of dropping coating layer 2 is reduced.

In order to more effectively suppress the falling of the coating layer 2, one of the above-described first condition and second condition may be satisfied. In order to more effectively suppress the falling of coating layer 2, both of the first condition and the second condition may be satisfied.

In the example shown in fig. 5, the first side wall surface 515 of the first member 51 and the guide body 8 (inner wall surface 81 of the guide body) are separated from each other, and as a result, a space 9 in which a part of the coating layer 2 can be located is formed between the first side wall surface 515 and the guide body 8 (inner wall surface 81 of the guide body). When the space 9 is formed between the first side wall 515 and the guide body 8, the coating layer 2 discharged from the peeler body 5 is guided more smoothly toward the guide hole 80. In addition, when there is a gap between the inner wall surface 801 of the guide hole 80 and the inner wall surface 57a of the coating layer discharge hole 57, the coating layer 2 discharged from the peeler body 5 can be theoretically guided toward the guide hole 80 without the space 9. However, in order to more smoothly guide the coating layer 2 discharged from the peeler body 5, it is preferable that a space 9 is formed between the first side wall 515 and the guide 8.

The first side wall 515 is a side surface of the first member 51 from which the coating layer 2 is discharged, that is, a discharge side surface.

The covered wire stripper in the first embodiment includes a guide body attached to the first member of the stripper body, the guide body having a guide hole capable of guiding the covering layer separated from the wire rod. As a result, the covered wire stripper in the first embodiment can achieve both effects of suppressing the peeled covering layer from being entangled with the stripper body and the like and suppressing the peeled covering layer from falling out in a synergistic manner.

(second embodiment)

The covered wire stripper 4 according to the second embodiment is explained with reference to fig. 6 to 9. Fig. 6 is a schematic front view showing an example of the covered wire stripper 4 according to the second embodiment. Fig. 6 shows a state in which the peeler body 5 of the covered wire peeler 4 is opened. Fig. 7 is a schematic side view showing an example of the covered wire stripper 4 according to the second embodiment. Fig. 7 shows a state in which the dehider body 5 is in a locked state. Fig. 8 is a schematic plan view showing an example of the covered wire stripper 4 according to the second embodiment. Fig. 9 is a schematic perspective view showing an example of the guide body 8 of the covered wire stripper 4 according to the second embodiment. Fig. 9 is a schematic plan view of the guide body 8 at the upper side, and fig. 9 is a schematic side view of the guide body 8 at the lower side.

The covered wire stripper 4 according to the second embodiment is different from the covered wire stripper according to the first embodiment in that the stripper body 5 includes a plurality of covered wire housing spaces (see fig. 6) when the stripper body 5 is in a locked state, the guide body 8 is adjustable in position in the third direction (see fig. 8), and the guide hole 80 is formed so as to straddle the guide body first portion 84 and the guide body second portion 85 of the guide body 8 (see fig. 9). The main surface (the surface having the largest area) of the first portion 84 of the guide body is not flush with the main surface (the surface having the largest area) of the second portion 85 of the guide body. In other words, the angle formed between the major face of the guide body first portion 84 and the major face of the guide body second portion 85 is greater than 0 degrees and less than 180 degrees. The angle formed between the main surface (the surface having the largest area) of the first portion 84 of the guide body and the main surface (the surface having the largest area) of the second portion 85 of the guide body is, for example, 45 degrees or more and 135 degrees or less, and more preferably 80 degrees or more and 100 degrees or less. In other respects, the covered wire stripper of the second embodiment is the same as the covered wire stripper of the first embodiment.

Refer to fig. 6. The first member 51 includes a third groove 55a in addition to the first groove 55. The second member 52 includes a fourth groove 56a in addition to the second groove 56. The third groove 55a is parallel to the first groove 55, and the fourth groove 56a is parallel to the second groove 56. When the dehider body 5 is in the locked state, the covered wire 1 is held in the space formed by the first groove 55 and the second groove 56. In other words, the first and

second grooves

55 and 56 cooperate to form a covered wire accommodating space that accommodates a part of the covered wire 1 when the dehider body 5 is in the locked state. On the other hand, when the covered wire to be peeled is a covered wire having a relatively large diameter, that is, when the covered wire 1a to be peeled is larger in diameter than the covered wire 1, the third groove 55a and the fourth groove 56a are used. When the dehider body is in the closed state, the covered wire 1a having a large diameter is held in the space formed by the third groove 55a and the fourth groove 56 a. In other words, the third and

fourth grooves

55a and 56a cooperate to form a second covered wire accommodating space that accommodates a part of the covered wire 1a when the dehider body 5 is in the locked state.

Further, the covered wire stripper 4 according to the second embodiment includes a second blade 7a and a second guide 8 a. The second blade 7a is attached to the first member 51, and separates the coated wire 1a into the coating layer 2a and the wire rod 3 a. The second guide body 8a is attached to the first member 51. The second guide 8a has a second guide hole 80a capable of guiding the coating layer 2a separated from the wire 3 a. The guide hole 80 of the guide body 8 is provided so as to face the first side wall surface 515 on the side where the first groove 55 is arranged. On the other hand, the second guide hole 80a of the second guide body 8a is provided so as to face the second side wall surface 516 on the side where the third groove 55a is arranged.

In the example shown in fig. 6, the number of covered wire accommodating spaces is 2, but the number of covered wire accommodating spaces provided in the peeler body 5 may be 3 or more.

Refer to fig. 8. The guide body 8 is attached to the first member 51 so as to be adjustable in position in the third direction. The guide body 8 is movable in a direction parallel to the top surface 59 of the first member 51. More specifically, the guide body 8 includes a long hole 83, and any attachment member such as the screw 12 is inserted into the long hole 83. For example, after the screw 12 is loosened from the first member 51, the guide body 8 is slidably moved in the third direction, and then the screw 12 is fastened to the first member 51, whereby the position of the guide body 8 with respect to the first member 51 is adjusted. The mechanism for adjusting the position of the guide body 8 is not limited to the mechanism shown in fig. 8. As the position adjusting mechanism of the guide body 8, any mechanism can be adopted. For example, the first member 51 may be provided with rack teeth, and the guide body 8 may be provided with claws that can engage with the rack teeth. In this case, the guide body 8 is arranged so as to be capable of multi-stage position adjustment with respect to the first member 51.

The interval L1 between the first side wall surface 515 of the first member 51 and the guide body 8 (the inner wall surface 81 of the guide body) is preferably set so that the separated coating layer 2 can be smoothly guided and a part of the separated coating layer 2 can be held between the guide body 8 and the first side wall surface 515. The optimum value of the interval L varies depending on the thickness of the coating layer 2 or the material of the coating layer 2.

In the second embodiment, the guide body 8 is attached to the first member 51 so as to be adjustable in position in the third direction. Therefore, the interval L1 between the first side wall surface 515 of the first member 51 and the guide 8 (the inner wall surface 81 of the guide) can be set to be optimum in accordance with the characteristics of the coating layer 2.

In the second embodiment, it is preferable that the second guide body 8a is also attached to the first member 51 so as to be adjustable in position along the third direction. More specifically, the second guide 8a may have a long hole 83a, and an arbitrary attachment member such as the screw 12a may be inserted into the long hole 83 a. The interval between the second side wall surface 516 of the first member 51 and the second guide body 8a (the inner wall surface of the second guide body) is preferably set in such a manner that: the separated coating layer 2a can be smoothly guided and a part of the separated coating layer 2a can be held between the second guide 8a and the second side wall surface 516.

Further, the configuration in which the guide body 8 is attached to the first member 51 so as to be adjustable in position along the third direction is also applicable to the first embodiment.

Next, an example of a specific configuration of the guide body 8 in the second embodiment will be described with reference to fig. 9. Fig. 9 is a schematic plan view of the guide body 8 at the upper side, and fig. 9 is a schematic side view of the guide body 8 at the lower side. In the example shown in fig. 9, the guide body 8 includes: a guide body first portion 84 parallel to the top surface 59 of the first member 51 (the surface opposite to the surface on which the first groove 55 is formed); and a guide body second portion 85 parallel to the side surface (first side wall surface 515) of the first member 51. That is, when the guide body 8 is viewed in the first direction, the guide body 8 has an L shape (see fig. 6). In the example shown in fig. 9, the first portion 84 of the guide body is parallel to the top surface 59 of the first member 51, and the second portion 85 of the guide body is parallel to the side surface of the first member 51. Alternatively, the guide body first portion 84 may be non-parallel with respect to the top surface 59 of the first member 51. Also, the guide body second portion 85 may also be non-parallel with respect to the side of the first member 51.

The guide first portion 84 is attached to the first member 51 by an arbitrary attachment member such as the screw 12. In the example shown in fig. 9, a hole (for example, an elongated hole 83) for receiving an attachment member such as the screw 12 is provided in the guide body first portion 84. By attaching the guide body 8 to the first member 51, the guide body first portion 84 is brought into close contact with the top surface 59 of the first member 51.

As is understood from the upper side view (plan view) of fig. 9, a guide hole first portion 810 is formed in the guide body first portion 84. As is understood from the lower side view (side view) of fig. 9, a guide hole second portion 820 is formed in the guide body second portion 85. The guide hole first portion 810 and the guide hole second portion 820 communicate with each other. In other words, the via first portion 810 and the via second portion 820 form one via 80.

In the example shown in fig. 9, the guide hole 80 is formed by a guide hole first portion 810 formed in the guide body first portion 84 and a guide hole second portion 820 formed in the guide body second portion 85. Therefore, the coating layer 2 discharged from the peeler body 5 can be smoothly guided in a direction obliquely upward, in other words, in a direction away from both the first side wall surface 515 of the first member 51 and the top surface 59 of the first member 51. As a result, the coating layer 2 separated from the wire 3 can be more effectively prevented from being entangled with the peeler body or the like.

The shape of the elongated hole 83 may be changed as necessary, or the guide body 8 may be slidably moved in the first direction by adjusting the width of the elongated hole 83 in the first direction and the diameters of the head portion and the screw portion of the screw 12. By sliding the guide body 8 in the first direction, the contact between a part of the coating layer 2 separated by the bit 71 and the first direction end of the guide hole 80 can be adjusted. The configuration of the guide body 8 shown in fig. 9 is a configuration that can be adopted in the first embodiment.

The covered wire stripper in the second embodiment has a plurality of covered wire accommodating spaces having mutually different diameters. Therefore, the same covered wire stripper can be used for covered wires having different diameters. In the covered wire stripper according to the second embodiment, the guide body is attached to the first member so as to be adjustable in position. Therefore, the distance between the guide and the peeler body can be optimally set according to the characteristics of the coating layer to be peeled. In this way, the peeling layer that has been completely cut from the wire rod can be prevented from falling off more effectively. In the covered wire stripper according to the second embodiment, the guide hole is formed so as to straddle the first portion of the guide body and the second portion of the guide body. Therefore, the coating layer 2 discharged from the peeler body 5 can be preferably guided obliquely upward. Thus, the coating layer can be more effectively prevented from being entangled with the peeler body or the like.

(case where the covered wire is peeled off spirally)

When the coating layer is spirally peeled off from the wire, a thread (spiral protrusion) may be provided on the cylindrical surface formed by the first groove 55 and the second groove 56. A specific example of the screw is shown in fig. 3 of patent document 1. On the other hand, when the coating layer is peeled off from the wire rod in the circumferential direction, it is not necessary to provide a screw or the like on the cylindrical surface constituted by the first groove 55 and the second groove 56.

Fig. 10 is a photograph replacing the drawings. Fig. 10 is a photograph showing an example of a state in which the separated coating layer is held between the guide and the peeler body after the peeling operation.

(first example of the mode of use of the covered wire stripper)

Fig. 11 is a conceptual diagram illustrating an example of a usage form of the covered wire stripper according to the embodiment. In the example shown in fig. 11, a grip 100 that can be gripped by a worker is attached to the covered wire stripper 4. In the example shown in fig. 11, the operator holds the first grip 101 with one hand and the second grip 102 with the other hand. Then, the covered wire stripper 4 is rotated around the covered wire 1 together with the grip portion 100 (see an arrow R2 in fig. 11), thereby stripping the covered wire.

(second example of the mode of use of covered wire stripper)

Fig. 12 is a conceptual diagram showing another example of the usage form of the covered wire stripper according to the embodiment. In the example shown in fig. 12, the covered wire stripper 4 is attached to the rotary operating rod 110 via the power transmission mechanism 120. By rotating the rotating operation rod 110 in the R3 direction, the covered wire stripper 4 is rotated in the R4 direction. As the power transmission mechanism 120, any power transmission mechanism such as a bevel gear can be used. In the example shown in fig. 12, the peeling operation of the covered wire located at a position distant from the position of the operator can be performed. In the example shown in fig. 12, the rotation operation rod 110 is manually rotated. Alternatively, the covered wire stripper 4 may be automatically rotated around the covered wire 1 using an electric motor or the like.

(availability in industry)

When the covered wire stripper of the present invention is used, the coating layer separated from the covered wire can be effectively prevented from being entangled with the stripper body and the like. Therefore, the efficiency of the peeling work is not lowered. Further, when the covered wire stripper of the present invention is used, the covering layer separated from the covered wire can be effectively prevented from dropping. As a result, the operation of collecting the dropped coating layer is not required. Therefore, it is useful for a worker who handles the covered wire, for example, for a worker who connects the electric wire.
