Description

[Technical field]

[0001] The present invention relates to a wire guide attached to a wire coating layer scraper that scrapes off the coating layer of a low-voltage wire or the like, and to a wire coating layer scraper equipped with the wire guide. [Background technology]

[0002] Conventionally, workers would insert an electric wire into the electric wire insertion hole of the electric wire insulation layer scraper, and then rotate the electric wire insulation layer scraper in that state to scrape off the insulation layer of the electric wire with the cutting blade built into the electric wire insulation layer scraper. However, since the diameter and shape of the electric wire differ depending on the type of electric wire, the inserted electric wire would twist inside the electric wire insertion hole, making it difficult to properly scrape off the insulation layer.

[0003] [Patent Document 1] Patent No. 4283778 Summary of the Invention [Problem to be solved by the invention]

[0004] Therefore, in consideration of the above problems, the present invention provides a wire guide that can stably scrape off the coating layer so as to be compatible with various types of wires, and a wire coating layer scraper equipped with the wire guide. [Means for solving the problem]

[0005] In order to solve the above problems, the wire guide of the present invention is an electric wire guide attached to a wire coating layer scraper, and comprises a base provided with a first guide hole and a second guide hole through which an electric wire can be inserted, and a first guide portion extending from the first guide hole of the base and inserted into a wire insertion hole of the wire coating layer scraper, and is characterized in that the base is detachably attached to the wire coating layer scraper so that the first guide hole and the second guide hole can be alternately aligned in a straight line with the wire insertion hole of the wire coating layer scraper.

[0006] According to the above-mentioned features, the guide hole can be easily changed to an appropriate one according to the diameter, shape, etc. of the electric wire, and the coating layer can be stably scraped off.

[0007] Furthermore, in order to solve the above problem, the wire guiding tool of the present invention is characterized in that when the second guide hole is aligned in a straight line with the wire insertion hole of the wire coating layer scraper, the first guide portion abuts against a recess in the outer wall of the wire coating layer scraper.

[0008] According to the above feature, even if the wire guide is about to rotate due to an external force when scraping off the coating layer of the wire, the first guiding portion can abut against the recess of the wire coating layer scraper to prevent the rotation.

[0010] According to the above feature, the wire guide is fixed to the wire coating layer scraper by magnetic force, so that it can be easily attached and detached.

[0011] Furthermore, in order to solve the above problem, the wire guide of the present invention is characterized in that the base is fixed to the mounting portion of the wire coating layer scraper by a protrusion and a hole portion into which the protrusion is inserted.

[0012] According to the above feature, the wire guide is firmly fixed so as not to rotate on the mounting portion.

[0013] Furthermore, in order to solve the above-mentioned problems, the wire guiding tool of the present invention is characterized in that the base has a third guide hole through which the electric wire can be inserted, and a second guide portion extends from the second guide hole of the base and is inserted into the wire insertion hole of the wire coating layer scraper, and when the third guide hole is aligned in a straight line with the wire insertion hole of the wire coating layer scraper, the second guide portion abuts against a recess in the outer wall of the wire coating layer scraper.

[0014] According to the above feature, the first guiding portion and the second guiding portion abut against the recesses at two locations, thereby effectively preventing rotation of the wire guiding tool.

[0015] Furthermore, in order to solve the above-mentioned problems, the present invention provides an electric wire coating layer scraper comprising the above-mentioned electric wire guide.

[0016] According to the above-mentioned features, the guide hole can be easily changed to an appropriate one according to the diameter, shape, etc. of the electric wire, and the coating layer can be stably scraped off. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, the embodiments of the present invention will be described with reference to the drawings. Note that the shapes of the figures referred to in the following description are conceptual or schematic diagrams for explaining preferred shapes and dimensions, and the dimensional ratios do not necessarily match the actual dimensional ratios. In other words, the present invention is not limited to the dimensional ratios in the drawings.

[0020] First, Fig. 1 and Fig. 2 show a wire coating layer scraper 600 to which the wire guide 100 of the present invention is attached. Fig. 1 is an overall perspective view of the wire coating layer scraper 600, Fig. 2(a) is an exploded view of the wire coating layer scraper 600 cut in the center and exploded to clearly explain the internal structure, and Fig. 2(b) is a side view of the wire coating layer scraper 600.

[0021] The wire coating layer scraper 600 has a cylindrical shape with a wire insertion hole 630 in the center for inserting the wire, and is entirely made of synthetic resin, etc. The wire insertion hole 630 extends linearly along the longitudinal direction of the wire coating layer scraper 600.

[0022] Further, a plurality of recesses 603 are provided on the outer peripheral wall 602 of the electric wire coating layer scraper 600. The recesses 603 have a cross section that is recessed inward in a substantially semicircular shape, and extend linearly along the longitudinal direction of the electric wire coating layer scraper 600. By providing the recesses 603, the surface of the outer peripheral wall 602 of the electric wire coating layer scraper 600 becomes uneven, making it easy for an operator to hold and rotate the electric wire coating layer scraper 600 by hand. Note that the recesses 603 have a cross section that is recessed inward in a substantially semicircular shape, but are not limited to this, and may be any shape.

[0023] Further, the electric wire insertion hole 630 is provided with a through hole 631 penetrating from the inside to the outside. A scraping blade 609 is attached at a position adjacent to the through hole 631, and a tip of the scraping blade 609 protrudes to the inside of the electric wire insertion hole 630. Therefore, when the electric wire coating layer scraper 600 is rotated with the electric wire inserted into the electric wire insertion hole 630, the scraping blade 609 scrapes off the coating layer of the electric wire, and the scraped off coating layer is discharged to the outside via the through hole 631.

[0024] Further, the electric wire insertion hole 630 is provided with a confirmation window 632 extending along the longitudinal direction of the electric wire insertion hole 630. The confirmation window 632 penetrates from the inside to the outside, and the electric wire inserted into the electric wire insertion hole 630 can be visually confirmed from the outside. Then, the worker can confirm how much of the wire's covering has been stripped through the confirmation window 632. Note that a scale 633 is provided on the outer surface of the confirmation window 632, and can be used as a guide to measure the length of the wire's covering that has been stripped. The scale 633 is formed of grooves, but is not limited to this, and the scale 633 may be of any other configuration, such as a configuration in which the scale 633 is drawn in the form of lines with paint or the like.

[0025] The end surface on the tip side of the wire coating layer scraper 600 is a mounting part 640 for mounting the wire guide 100 described later. The mounting part 640 is a flat surface so that the wire guide 100 can be stably mounted. Furthermore, a metal body 641 is disposed on the mounting part 640 so that the wire guide 100 can be attached and detached by magnetic force. Furthermore, a protrusion 642 is disposed on the mounting part 640 to be inserted into a hole of the wire guide 100. Note that the mounting part 640 is a flat surface, but is not limited thereto, and may have any shape as long as the wire guide 100 can be attached.

[0026] Next, the electric wire guide 100 of the present invention is shown in Fig. 3 and Fig. 4. Fig. 3(a) is an overall perspective view of the right front side of the electric wire guide 100, Fig. 3(b) is an overall perspective view of the left front side of the electric wire guide 100, Fig. 3(c) is an overall perspective view of the back side of the electric wire guide 100, Fig. 4(a) is a front view of the electric wire guide 100, Fig. 4(b) is a back view of the electric wire guide 100, and Fig. 4(c) is a side view of the electric wire guide 100.

[0027] The electric wire guide 100 includes a flat plate-like base 110, and is entirely made of synthetic resin or the like. The base 110 has a generally triangular shape in a plan view, and a first guide hole 120, a second guide hole 130, and a third guide hole 140 are provided at each corner. The first guide hole 120, the second guide hole 130, and the third guide hole 140 are shaped to penetrate from front to back so that an electric wire can be inserted. The second guide hole 130 has a larger diameter than the first guide hole 120 so that an electric wire with a larger diameter can be inserted. The third guide hole 140 has a larger diameter than the second guide hole 130 so that an even larger diameter electric wire can be inserted.

[0028] Moreover, the inner surface 121 of the first guide hole 120 is inclined from the tip 122 side of the front surface to the end 123 side of the back surface, so that the first guide hole 120 is configured to have a smaller diameter from the tip 122 to the end 123. Similarly, the inner surface 131 of the second guide hole 130 is inclined from the tip 132 side of the front surface to the end 133 side of the back surface, so that the second guide hole 130 is configured to have a smaller diameter from the tip 132 to the end 133. Similarly, the inner surface 141 of the third guide hole 140 is inclined from the tip 142 side of the front surface to the end 143 side of the back surface, so that the third guide hole 140 is configured to have a smaller diameter from the tip 142 to the end 143.

[0029] A cylindrical first guide portion 150 extending toward the rear side is provided on the rear surface of the first guide hole 120. The first guide portion 150 is configured so as to be able to be inserted into the electric wire insertion hole 630 of the electric wire coating layer scraper 600, and further includes an insertion hole 151 through which the electric wire can be inserted. The insertion hole 151 and the first guide hole 120 are arranged in a straight line and communicate with each other. An opening 152 opening toward the side is provided in a part of the insertion hole 151, and the opening 152 is arranged so as to face the through hole 631 of the electric wire insertion hole 630 and the scraping blade 609 when the first guide portion 150 is inserted into the electric wire insertion hole 630.

[0030] A cylindrical second guide portion 160 extending toward the rear side is provided on the rear surface of the second guide hole 130. The second guide portion 160 is configured so as to be insertable into the electric wire insertion hole 630 of the electric wire coating layer scraper 600, and further includes an insertion hole 161 through which the electric wire can be inserted. The insertion hole 161 and the second guide hole 130 are arranged in a straight line and communicate with each other. An opening 162 opening toward the side is provided in a part of the insertion hole 161, and the opening 162 is arranged so as to face the through hole 631 of the electric wire insertion hole 630 and the scraping blade 609 when the second guide portion 160 is inserted into the electric wire insertion hole 630.

[0031] A magnet 170 is attached to the center of the back surface of the base 110. The magnet 170 can be coupled to a metal body 641 of the wire coating layer scraper 600 by magnetic force. A plurality of holes 180 are provided on the back surface of the base 110. The holes 180 are configured so that the protrusions 642 of the wire coating layer scraper 600 can be inserted therein.

[0032] Although the magnet 170 is attached to the base 110 and the metal body 641 is attached to the wire coating layer scraper 600, the present invention is not limited to this, and the metal body 641 may be attached to the base 110 and the magnet 170 may be attached to the wire coating layer scraper 600. Any other configuration may be used as long as the base 110 can be attached to the wire coating layer scraper 600 by magnetic force. Furthermore, although the base 110 is attached to the wire coating layer scraper 600 by magnetic force, the present invention is not limited to this, and any other configuration may be used as long as the base 110 can be detachably fixed to the wire coating layer scraper 600 by Velcro (registered trademark), a suction cup, adhesive, or the like. In addition, the base 110 is provided with the hole 180, and the wire coating layer scraper 600 is provided with the protrusion 642, but the present invention is not limited to this, and the base 110 may be provided with the protrusion 642, and the wire coating layer scraper 600 may be provided with the hole 180. In addition, the wire guide 100 is fixed to the wire coating layer scraper 600 by the magnetic force of the magnet 170 and the fitting force between the hole 180 and the protrusion 642, but the present invention is not limited to this, and the wire guide 100 may be fixed to the wire coating layer scraper 600 only by the magnetic force of the magnet 170 or only by the fitting force between the hole 180 and the protrusion 642.

[0033] The first guide hole 120, the second guide hole 130, and the third guide hole 140 may have any shape or size as long as the electric wire can be inserted therethrough. The base 110 has three guide holes, but is not limited thereto, and may have two guide holes or four or more guide holes. The first guide hole 120 has a first guide portion 150, but is not limited thereto, and may not have the first guide portion 150. The second guide hole 130 has a second guide portion 160, but is not limited thereto, and may not have the second guide portion 160. The third guide hole 140 does not have a guide portion extending to the back side, but is not limited thereto, and may have a guide portion extending to the back side.

[0034] Next, a mode of attaching the electric wire guiding tool 100 to the electric wire coating layer scraper 600 will be described with reference to Fig. 5. Fig. 5(a) is an overall perspective view of the electric wire guiding tool 100 before being attached to the electric wire coating layer scraper 600, Fig. 5(b) is a rear view of the electric wire guiding tool 100 attached to the electric wire coating layer scraper 600, and Fig. 5(c) is a plan view of the electric wire guiding tool 100 attached to the electric wire coating layer scraper 600.

[0035] First, in Fig. 5(a), it is assumed that the coating layer of a large diameter electric wire is scraped off. In this case, the third guide hole 140, which has the largest diameter, of the electric wire guide 100 is arranged in a straight line with the electric wire insertion hole 630 of the electric wire coating layer scraper 600. Specifically, the electric wire guide 100 is directed to the mounting part 640 of the electric wire coating layer scraper 600 so that the third guide hole 140 is aligned in a straight line with the electric wire insertion hole 630 of the electric wire coating layer scraper 600, and the magnet 170 of the electric wire guide 100 and the metal body 641 of the electric wire coating layer scraper 600 are coupled by magnetic force. Then, the electric wire guide 100 is attached to the mounting part 640 of the electric wire coating layer scraper 600. At this time, since the projection 642 of the mounting portion 640 is inserted into the hole 180 of the wire guide 100 , the wire guide 100 is firmly fixed on the mounting portion 640 so as not to rotate.

[0036] When scraping off the coating layer of the electric wire, the worker holds and rotates the electric wire coating layer scraper 600 while inserting the electric wire from the third guide hole 140 into the electric wire insertion hole 630. The coating layer of the electric wire in the electric wire insertion hole 630 is scraped off by the scraping blade 609 and discharged to the outside from the through hole 631. Furthermore, the worker moves the electric wire coating layer scraper 600 along the electric wire while rotating it (moves it to the left in the drawing), and the coating layer of the electric wire is scraped off in a spiral shape by a predetermined length. At that time, the electric wire is pushed from the third guide hole 140 into the electric wire insertion hole 630. Since the inner surface 141 of the third guide hole 140 is inclined toward the electric wire insertion hole 630, even if the electric wire is slightly crushed or bulged, the electric wire can be fed straight toward the electric wire insertion hole 630, and the coating layer can be stably stripped off.

[0037] As shown in FIG. 5(b), the first guiding part 150 and the second guiding part 160 of the electric wire guide 100 are arranged to fit into the recess 603 of the electric wire coating layer scraper 600. Therefore, even if the electric wire guide 100 is about to rotate due to an external force when scraping off the coating layer of the electric wire, the first guiding part 150 and the second guiding part 160 of the electric wire guide 100 abut against the recess 603 of the electric wire coating layer scraper 600 to prevent the rotation. As a result, the coating layer can be stably peeled off. In particular, since the first guiding part 150 and the second guiding part 160 abut against the recess 603 at two points, the rotation of the electric wire guide 100 is effectively prevented.

[0038] Next, a mode of replacing the electric wire guiding tool 100 with the electric wire coating layer scraper 600 will be described with reference to Fig. 6. Fig. 6(a) is an overall perspective view of the electric wire guiding tool 100 before being attached to the electric wire coating layer scraper 600, Fig. 6(b) is a rear view of the electric wire guiding tool 100 attached to the electric wire coating layer scraper 600, and Fig. 6(c) is a plan view of the electric wire guiding tool 100 attached to the electric wire coating layer scraper 600.

[0039] In Fig. 6(a), it is assumed that the coating layer of an electric wire having a smaller diameter than the electric wire described in Fig. 5 is to be scraped off. In this case, first, the electric wire guide 100 is removed from the electric wire coating layer scraper 600 from the state shown in Fig. 5. The electric wire guide 100 is fixed to the electric wire coating layer scraper 600 by magnetic force, so that it can be easily attached and detached. Then, as shown in Fig. 6(a), the position of the electric wire guide 100 is rotated so that the second guide hole 130 having the second largest diameter of the electric wire guide 100 is aligned in a straight line with the electric wire insertion hole 630 of the electric wire coating layer scraper 600. Specifically, the wire guide 100 is rotated and aligned with the mounting portion 640 of the wire coating layer scraper 600 so that the second guide hole 130 is aligned in a straight line with the wire insertion hole 630 of the wire coating layer scraper 600, and the second guide portion 160 extending from the second guide hole 130 is inserted into the wire insertion hole 630, and the magnet 170 and the metal body 641 of the wire guide 100 are fixed by magnetic force. Then, the wire guide 100 is attached to the mounting portion 640 of the wire coating layer scraper 600. At this time, since the protrusion 642 of the mounting portion 640 is inserted into the hole portion 180 of the wire guide 100, the wire guide 100 is firmly fixed so as not to rotate on the mounting portion 640.

[0040] When scraping off the coating layer of the electric wire, the operator holds and rotates the electric wire coating layer scraper 600 while the electric wire is inserted into the electric wire insertion hole 630 of the electric wire coating layer scraper 600. Specifically, the electric wire is inserted from the second guide hole 130 and inserted into the insertion hole 161 of the second guide part 160. Furthermore, the electric wire is inserted from the insertion hole 161 of the second guide part 160 into the electric wire insertion hole 630 of the electric wire coating layer scraper 600. As shown in FIG. 6(c), when the second guide part 160 is inserted into the electric wire insertion hole 630, the opening 162 of the second guide part 160 overlaps with the through hole 631 of the electric wire insertion hole 630.

[0041] Then, with the electric wire inserted into the insertion hole 161 of the second guiding part 160 and the electric wire insertion hole 630 of the electric wire coating layer scraper 600, the worker grasps and rotates the electric wire coating layer scraper 600. The coating layer of the electric wire in the insertion hole 161 of the second guiding part 160 is scraped off by the scraping blade 609 and discharged to the outside from the through hole 631. Furthermore, when the worker moves the electric wire coating layer scraper 600 along the electric wire while rotating it (moving it to the left in the drawing), the coating layer of the electric wire is scraped off in a spiral shape by a predetermined length. At that time, the electric wire is pushed from the second guiding hole 130 into the electric wire insertion hole 630. Since the inner surface 131 of the second guide hole 130 is inclined toward the second guide portion 160 and the electric wire insertion hole 630, even if the electric wire is slightly crushed or bulged, the electric wire can be fed straight toward the second guide portion 160 and the electric wire insertion hole 630, and the coating layer can be stably stripped off.

[0042] 6(b), the first guiding part 150 of the electric wire guide 100 is arranged to fit into the recess 603 of the electric wire coating layer scraper 600. Therefore, even if the electric wire guide 100 is about to rotate due to an external force when scraping off the coating layer of the electric wire, the first guiding part 150 of the electric wire guide 100 abuts against the recess 603 of the electric wire coating layer scraper 600 to prevent the rotation. As a result, the coating layer can be stably stripped off.

[0043] Next, a mode of replacing the electric wire guiding tool 100 with the electric wire coating layer scraper 600 will be described with reference to Fig. 7. Fig. 7(a) is an overall perspective view of the state before the electric wire guiding tool 100 is attached to the electric wire coating layer scraper 600, Fig. 7(b) is a rear view of the state in which the electric wire guiding tool 100 is attached to the electric wire coating layer scraper 600, and Fig. 7(c) is a plan view of the state in which the electric wire guiding tool 100 is attached to the electric wire coating layer scraper 600.

[0044] In Fig. 7(a), it is assumed that the coating layer of an electric wire having a smaller diameter than the electric wire described in Fig. 6 is to be scraped off. In this case, first, the electric wire guide 100 is removed from the electric wire coating layer scraper 600 from the state shown in Fig. 6. The electric wire guide 100 is fixed to the electric wire coating layer scraper 600 by magnetic force, so that it can be easily attached and detached. Then, as shown in Fig. 7(a), the position of the electric wire guide 100 is rotated so that the first guide hole 120 having the smallest diameter of the electric wire guide 100 is aligned in a straight line with the electric wire insertion hole 630 of the electric wire coating layer scraper 600. Specifically, the wire guide 100 is rotated and aligned with the mounting portion 640 of the wire coating layer scraper 600 so that the first guide hole 120 is aligned in a straight line with the wire insertion hole 630 of the wire coating layer scraper 600, and the first guide portion 150 extending from the first guide hole 120 is inserted into the wire insertion hole 630, and the magnet 170 and the metal body 641 of the wire guide 100 are fixed by magnetic force. Then, the wire guide 100 is attached to the mounting portion 640 of the wire coating layer scraper 600. At this time, since the protrusion 642 of the mounting portion 640 is inserted into the hole portion 180 of the wire guide 100, the wire guide 100 is firmly fixed so as not to rotate on the mounting portion 640.

[0045] When scraping off the coating layer of the electric wire, the operator holds and rotates the electric wire coating layer scraper 600 while the electric wire is inserted into the electric wire insertion hole 630 of the electric wire coating layer scraper 600. Specifically, the electric wire is inserted from the first guide hole 120 and inserted into the insertion hole 151 of the first guide part 150. Furthermore, the electric wire is inserted from the insertion hole 151 of the first guide part 150 into the electric wire insertion hole 630 of the electric wire coating layer scraper 600. As shown in FIG. 7(c), when the first guide part 150 is inserted into the electric wire insertion hole 630, the opening 152 of the first guide part 150 overlaps with the through hole 631 of the electric wire insertion hole 630.

[0046] Then, with the electric wire inserted into the insertion hole 151 of the first guiding part 150 and the electric wire insertion hole 630 of the electric wire coating layer scraper 600, the worker grasps and rotates the electric wire coating layer scraper 600. The coating layer of the electric wire in the insertion hole 151 of the first guiding part 150 is scraped off by the scraping blade 609 and discharged to the outside from the through hole 631. Furthermore, when the worker moves the electric wire coating layer scraper 600 along the electric wire while rotating it (moves it to the left in the drawing), the coating layer of the electric wire is scraped off in a spiral shape by a predetermined length. At that time, the electric wire is pushed from the first guiding hole 120 into the electric wire insertion hole 630. Since the inner surface 121 of the first guide hole 120 is inclined toward the first guide portion 150 and the electric wire insertion hole 630, even if the electric wire is slightly crushed or bulged, the electric wire can be fed straight toward the first guide portion 150 and the electric wire insertion hole 630, and the coating layer can be stably stripped off.

[0047] 7(b), the second guiding part 160 of the electric wire guide 100 is arranged to fit into the recess 603 of the electric wire coating layer scraper 600. Therefore, even if the electric wire guide 100 is about to rotate due to an external force when scraping off the coating layer of the electric wire, the second guiding part 160 of the electric wire guide 100 abuts against the recess 603 of the electric wire coating layer scraper 600 to prevent the rotation. As a result, the coating layer can be stably stripped off.

[0048] If the wire insertion hole 630 has a large gap with respect to the wire, the wire is likely to slip inside the wire insertion hole 630, making it difficult to stably scrape off the coating layer. Therefore, as shown in Fig. 5 to Fig. 7, the wire guide 100 of the present invention is designed to be easily changed to an appropriate guide hole according to the diameter, shape, etc. of the wire. The guide hole makes it difficult for the wire to slip inside the wire insertion hole 630, making it possible to stably scrape off the coating layer.
