  However, according to the technique disclosed in Patent Document 1, while aligning as accurately as possible the second edge portion to which the double-sided adhesive tape has been applied in advance and the portion where the second edge portion of the wire protection sheet overlaps, It is necessary to perform a bonding operation using a double-sided adhesive tape, which is difficult.

  Here, if a plurality of first extending pieces and a plurality of second extending pieces as disclosed in Patent Document 2 are provided on each of the facing edges of the wire protecting sheet, The opposing edges can be easily maintained in a combined state.

  However, in this case, there is a problem that the length in the circumferential direction of the wire protection sheet that covers the plurality of wires cannot be adjusted when the number of wires to be protected changes.

  Therefore, the present invention is capable of easily uniting opposing ends of an electric wire protection sheet wound around an electric wire and easily adjusting the circumferential length of the electric wire protection sheet covering the electric wire. With the goal.

  In order to solve the above problem, the electric wire with a protective member according to the first aspect is formed by an electric wire protection sheet in which at least one electric wire and a first end and a second end facing the outer periphery are formed. A protection member that protects the at least one electric wire in a state where the electric wire protection sheet is wound around the at least one electric wire, and the first end portion of the electric wire protection sheet includes: A plurality of first vertical slits inward from the first end are formed, and at least a first horizontal slit intersecting each of the plurality of first vertical slits extends along the extending direction of the first end. One row is formed, and a plurality of second vertical slits inward from the second end portion are formed in the second end portion of the wire protection sheet, and intersect with each of the plurality of second vertical slits. The second horizontal slit is A plurality of first vertical slits in the first end portion are formed in a plurality of rows along the extending direction of the two end portions, and the wire protection sheet is wound around the at least one electric wire once. And the portions divided by the plurality of second vertical slits of the second end portion are alternately combined, and the first lateral slit of the first end portion. The portion on the tip side is selectively locked to each portion on the tip side of the plurality of rows of the second horizontal slits in the second end portion.

  A 2nd aspect is an electric wire with a protection member which concerns on a 1st aspect, Comprising: At least one of the said 1st horizontal slit and the said 2nd horizontal slit is made into the cut formed in linear form.

  A 3rd aspect is an electric wire with a protection member which concerns on the 1st or 2nd aspect, Comprising: At least one of the said 1st vertical slit and the said 2nd vertical slit is made into the cut formed in linear form. ing.

  A 4th aspect is an electric wire with a protection member which concerns on any one 1st-3rd aspect, Comprising: In the at least 1 location of the edge part of the said 1st horizontal slit, and the edge part of the said 2nd horizontal slit The hole which draws an arc shape toward those outside is formed.

  A 5th aspect is an electric wire protection sheet which winds around at least one electric wire and protects an electric wire, Comprising: The 1st end part and 2nd end part which oppose outer periphery are formed, The said 1st end part In addition, a plurality of first longitudinal slits extending inward from the first end portion are formed, and first transverse slits that intersect each of the plurality of first longitudinal slits extend along the extending direction of the first end portion. A plurality of second longitudinal slits formed in the second end portion inward from the second end portion and intersecting each of the plurality of second longitudinal slits. Are formed in a plurality of rows along the extending direction of the second end portion.

  According to the first to fourth aspects, each portion of the first end portion divided by the plurality of first vertical slits in the state where the wire protection sheet is wound around at least one electric wire, and the second While combining each part divided | segmented by the several 2nd vertical slit among edge parts alternately, the part of the front end side rather than the said 1st horizontal slit among 1st edge parts is several in 2nd edge part. By selectively locking each part on the tip side of the second horizontal slit in the row, the opposing ends of the wire protection sheet wound around the wire can be easily combined and the wire covering the wire The object is to enable easy adjustment of the circumferential length of the protective sheet.

  Hereinafter, the electric wire with a protective member and the electric wire protection sheet according to the embodiment will be described. FIG. 1 is a schematic perspective view showing an electric wire 10 with a protective member, FIG. 2 is a plan view showing an electric wire protection sheet 30, and FIGS. 3 and 4 show a state in which ends of the electric wire protection sheet 30 are combined. It is explanatory drawing shown.

  The protective member-attached electric wire 10 includes at least one electric wire 12 and a protective member 20.

  The electric wire 10 with a protective member only needs to include at least one electric wire 12. Therefore, the protective member-attached electric wire 10 may include a single electric wire 12 or a plurality of electric wires 12. Here, the latter example, that is, an example including a bundle of electric wires 12 will be described. In FIG.1 and FIG.2, the outline of the bundle | flux of the some electric wire 12 is shown.

  The electric wire 12 is configured such that a covering portion is formed by extrusion coating of resin on the outer periphery of the core wire. The plurality of electric wires 12 may be branched into a plurality inside or outside the protective member 20. In order to branch out the plurality of electric wires 12 within the protective member 20 and draw them out, it is preferable to form slits or holes in the protective member 20. Here, the plurality of electric wires 12 are bundled together at a place where the main protection member 20 is attached. An optical fiber or the like may be disposed along the electric wire 12. The electric wire 12 is used to electrically connect various electric devices mounted on a vehicle or the like in a state where the electric wire 12 is arranged at a location to be arranged on the vehicle or the like.

  The protection member 20 protects the electric wire 12 by covering an intermediate portion in the extending direction of the bundle of electric wires 12.

  The protection member 20 is formed by the electric wire protection sheet 30.

  The electric wire protection sheet 30 is formed of a sheet material such as PVC (polyvinyl chloride), PP (polypropylene), or non-woven fabric. As such a sheet material, it is preferable to use a material that is flexible enough to be wound so as to wrap the wire 12 or a bundle of wires 12 by bending without making a crease.

  The electric wire protection sheet 30 has a shape in which a first side 32 and a second side 42 facing the outer periphery are formed. Here, the electric wire protection sheet 30 is formed in a rectangular shape, and one side of the pair of opposite sides is a first side 32, and the other side opposite thereto is a second side 42. .

  The electric wire protection sheet 30 is wound around at least one electric wire 12 (here, a bundle of electric wires 12). Thereby, the protection member 20 which protects the electric wire 12 is comprised.

  As a configuration for maintaining the sheet in a state of covering the electric wire, a configuration using a double-sided adhesive tape can be considered. However, when using a double-sided pressure-sensitive adhesive tape, it is necessary to affix the double-sided pressure-sensitive adhesive tape to one end of the sheet, and when the double-sided pressure-sensitive adhesive tape is attached to the other end of the sheet, It is necessary to peel off the release paper. Also, this release paper becomes garbage. Further, dust may stick to the adhesive surface.

  Moreover, when the double-sided pressure-sensitive adhesive tape at one end of the sheet is attached to the double-sided pressure-sensitive adhesive tape at the other end of the sheet, it is necessary to accurately align the double-sided pressure-sensitive adhesive tape with the other end of the sheet. When this alignment cannot be performed accurately, for example, when one end and the other end of the sheet are inclined, it is necessary to remove the double-sided adhesive tape from the other end of the sheet and reapply it. Necessary. In this case, it is difficult to remove the double-sided adhesive tape from the other end of the sheet. Moreover, there is also a problem that the adhesive strength is reduced when the double-sided adhesive tape is reapplied.

  Further, when the wire protection sheet 30 is wound around at least one electric wire 12, the circumferential length L covering the outer periphery of the at least one electric wire 12 varies depending on the number of the electric wires 12, the outer diameter of the electric wires 12, and the like. . When the outer peripheral length of at least one electric wire 12 to be protected and the circumferential length L of the electric wire protection sheet 30 are greatly different, the electric wire protection sheet 30 becomes easy to move in the extending direction of the electric wire 12, Moreover, it is not preferable in terms of appearance. For this reason, it is preferable that the circumferential length L of the wire protection sheet 30 can be adjusted in accordance with the outer peripheral length of at least one electric wire 12 to be protected.

  Here, even if it does not use a double-sided adhesive tape, the 1st end part 33 and the 2nd end part 43 which the wire protection sheet 30 wound around the electric wire 12 can be united easily, and the electric wire 12 is covered. In order to easily adjust the circumferential length L of the wire protection sheet 30, the following configuration is employed.

  That is, a plurality of first vertical slits 34 facing inward from the first end portion 33 are formed in the first end portion 33 on the first side 32 side of the wire protection sheet 30. Here, the first vertical slit 34 is orthogonal to the first end portion 33 (more specifically, the first side 32). The plurality of first vertical slits 34 are formed at equal intervals in the extending direction of the first side 32.

  In each of the plurality of first vertical slits 34, a first horizontal slit 35 that intersects the first vertical slit 34 is formed. Here, one first horizontal slit 35 is formed at the tip of the first vertical slit 34. The first horizontal slits 35 formed in each of the plurality of first vertical slits 34 extend in a line along the extending direction of the first end portion 33 (more specifically, the first side 32). Is formed. The length dimension of the first horizontal slit 35 is a length dimension that does not divide the portion between the first vertical slits 34. Here, the length dimension of the first horizontal slit 35 is between the first vertical slits 34. It is set to the same extent as the width dimension. For this reason, the edge part of the 1st horizontal slit 35 reaches the center position of the 1st vertical slit 34 which adjoins among the electric wire protection sheets 30. FIG.

  Here, at least one (here, both) of the first vertical slit 34 and the first horizontal slit 35 is formed in a cut shape formed in a linear shape.

  The number of first vertical slits 34 is arbitrary, and a plurality of first vertical slits 34 may be formed at narrower intervals. Moreover, the 1st horizontal slit 35 may be formed in multiple rows like the 2nd horizontal slit 45 mentioned later.

  In addition, a plurality of second vertical slits 44 directed inward from the second end portion 43 are formed in the second end portion 43 on the second side 42 side of the wire protection sheet 30. Here, the second vertical slit 44 is orthogonal to the second end portion 43 (more specifically, the second side 42). Each second vertical slit 44 is formed at a position (in this case, a central position) between the first vertical slits 34 in the extending direction of the first side 32 and the second side 42. Further, the plurality of second vertical slits 44 are formed at equal intervals in the extending direction of the second side 42.

  In each of the plurality of second vertical slits 44, a plurality of second horizontal slits 45 intersecting the second vertical slit 44 are formed. Here, one second horizontal slit 45 is formed at the tip of the second vertical slit 44. In addition, at least one (three in this case) second horizontal slits 45 are formed in an intermediate portion in the extending direction of the second vertical slit 44. In each second vertical slit 44, a plurality of second horizontal slits 45 are formed at intervals. The interval between the second horizontal slits 45 may or may not be uniform. A plurality of rows of second horizontal slits 45 formed in each of the plurality of second vertical slits 44 are arranged in a plurality of rows along the extending direction of the second end portion 43 (more specifically, the second side 42). It is formed so as to extend. The length dimension of the second horizontal slit 45 is a length dimension that does not divide the portion between the second vertical slits 44. Here, the length dimension of the second horizontal slit 45 is between the second vertical slits 44. It is set to the same extent as the width dimension. For this reason, the edge part of the 2nd horizontal slit 45 reaches the center position of the 2nd vertical slit 44 which adjoins among the electric wire protection sheets 30. FIG.

  Here, at least one (here, both) of the second vertical slit 44 and the second horizontal slit 45 is formed in a line-like cut shape.

  In addition, a plurality of auxiliary horizontal slits 49 positioned in the same row as the plurality of second horizontal slits 45 are formed in the side portion positioned outside the second vertical slit 44 in the periphery of the wire protection sheet 30.

  The first end portion 33 and the second end portion 43 of the wire protection sheet 30 are combined and combined as follows.

  That is, a portion of the electric wire protection sheet 30 between the first end portion 33 and the second end portion 43 is wound around the electric wire 12 once. And each part divided | segmented by the 1st vertical slit 34 among the 1st edge part 33, and each part divided | segmented by the 2nd vertical slit 44 among the 2nd edge part 43 are the 1st edge part 33 and the 1st. The two end portions 43 are alternately combined along the extending direction.

  At this time, a portion of the first end portion 33 on the front end side (first side 32 side) with respect to the first horizontal slit 35 is on the front end side with respect to the plurality of rows of second horizontal slits 45 on the second end portion 43 ( It is selectively locked to each part on the second side 42 side.

  Here, the width dimension W <b> 1 of the portion between the first horizontal slits 35 adjacent in the column direction in the first end portion 33 is the same as half the interval dimension of the first horizontal slit 35. Moreover, the width dimension W2 of the part between the 2nd horizontal slits 45 adjacent in each row among the 2nd edge part 43 is the same as the half of the space | interval dimension of the 2nd horizontal slit 45. FIG. Since the interval dimension of the 1st horizontal slit 35 and the interval dimension of the 2nd horizontal slit 45 are the same, the width dimension W1 of the part between the 1st horizontal slits 35 adjacent in the column direction among the 1st edge parts 33 is shown. Is the same as the width dimension W2 of the portion between the second horizontal slits 45 adjacent in each row of the second end 43, and the length dimension of the first horizontal slit 35 and the length of the second horizontal slit 45 It is the same as the size.

  For this reason, the portion between the first horizontal slits 35 adjacent in the column direction in the first end portion 33 is disposed in the second horizontal slit 45 in an arbitrary row of the second end portion 43. can do. At the same time, in an arbitrary row of the second end portion 43, a portion between the second horizontal slits 45 adjacent to each other in the second end portion 43 is replaced with the first vertical slit 34 of the first end portion 33. Can be disposed within.

  By combining as described above, the first end portion 33 and the second end portion 43 are combined in a combined state.

  In such a combination, it is possible to select which of the plurality of rows of second horizontal slits 45 in the second end portion 43 is to be combined with the first end portion 33. This will be described with reference to FIGS. For convenience of explanation, in FIGS. 3 and 4, a portion of the second end portion 43 that overlaps the outside of the first end portion 33 is hatched.

  That is, as shown in FIG. 3, the second horizontal slit 45 in the row closer to the second side 42 is selected, and this second horizontal slit 45 is adjacent to the second end slit 33 in the row direction. If the part between the 1st horizontal slits 35 is arrange | positioned, the circumferential direction length L which covers the electric wire 12 among the electric wire protection sheets 30 will become comparatively long. For this reason, it is suitable for protecting a bundle of relatively thick wires 12.

  On the other hand, as shown in FIG. 4, the second horizontal slit 45 in the row far from the second side 42 is selected, and adjacent to the second horizontal slit 45 in the row direction of the first end portion 33. If the part between the 1st horizontal slits 35 is arrange | positioned, the circumferential direction length L which covers the electric wire 12 among the electric wire protection sheets 30 will become comparatively short. For this reason, it is suitable for protecting a bundle of relatively thin electric wires 12.

  The circumferential length L covering the electric wire 12 in the electric wire protection sheet 30 is arbitrarily adjusted when the electric wire protection sheet 30 is wound around the electric wire 12 according to the interval, number, etc. of the second lateral slits 45. Can do.

  In addition, the 1st end part 33 and the 2nd end part 43 which extend outside among the electric wire protection sheets 30 may be left as it is, and have been wound by the wound adhesive tape or double-sided adhesive tape etc. It may be maintained in a state where it is overlapped with the portion. Even in the latter case, the first end portion 33 and the second end portion 43 may be maintained in a state where the first end portion 33 and the second end portion 43 are overlapped with the wound portion by an adhesive tape or an adhesive tape. Even in the latter case, since the first end portion 33 and the second end portion 43 are maintained in the combined state by the above-described locking structure, the adhesive tape or double-sided adhesive tape or the like can be easily attached. Is called.

  According to the protective member-equipped electric wire 10 and the electric wire protection sheet 30 configured as described above, the first vertical portion of the first end portion 33 in the state where the electric wire protection sheet 30 is wound around at least one electric wire 12. Each part divided by the slit 34 and each part divided by the second vertical slit 44 in the second end 43 are alternately combined. A portion of the first end portion 33 on the front end side of the first horizontal slit 35 is selectively locked to a portion of the second end portion 43 on the front end side of the plurality of rows of second horizontal slits 45. doing. Thereby, the 1st end part 33 and the 2nd end part 43 which the electric wire protection sheet 30 wound around the electric wire 12 oppose can be easily maintained in the union | combined state. Moreover, the circumferential direction length L of the electric wire protection sheet 30 which covers the electric wire 12 can be easily adjusted by selecting one of the several rows in the 2nd edge part 43, and comprising the said engagement state.

  Moreover, according to the said structure, it becomes unnecessary to use a double-sided adhesive tape, and the protection member 20 can also be made cheap. But as above-mentioned, the 1st end part 33 and the 2nd end part 43 may be hold | maintained in the state piled up by the double-sided adhesive tape, the adhesive tape, etc. at the other part. Even in this case, since the first end portion 33 and the second end portion 43 are maintained in the combined state, a failure in bonding of the double-sided adhesive tape and the adhesive tape is suppressed.

  Moreover, the 1st horizontal slit 35 and the 2nd horizontal slit 45 are made into the cut formed in the linear form. For this reason, the portion between the first vertical slits 34 in the first end portion 33 is difficult to be removed from between the second horizontal slits 45, and the portion between the second vertical slits 44 in the second end portion 43 is not the first horizontal slit. It becomes difficult to remove from between the slits 35. For this reason, the locked state is not easily released, and the combined state of the first end portion 33 and the second end portion 43 is more reliably maintained.

  Moreover, the 1st vertical slit 34 and the 2nd vertical slit 44 are made into the cut formed in linear form. For this reason, the portion of the first end portion 33 divided by the plurality of first vertical slits 34 is difficult to come out through the second vertical slit 44, and the second end portion 43 has a plurality of second ends. The portion divided by the vertical slit 44 hardly passes through the first vertical slit 34 to the outside. Therefore, each portion of the first end portion 33 divided by the plurality of first vertical slits 34 and each portion of the second end portion 43 divided by the plurality of second vertical slits 44 are alternately assembled. The combined state is more reliably maintained, and the combined state of the first end portion 33 and the second end portion 43 is more reliably maintained.

  Various modifications will be described based on the above embodiment.

  In the electric wire protection sheet 130 according to the first modification shown in FIG. 5, holes that draw an arc shape that protrudes outwardly toward both ends of the first horizontal slit 35 and both ends of the second horizontal slit 45. 35h and 45h are formed. Here, the holes 35h and 45h are formed in a circular shape. In addition, the hole may be elliptical.

  In the direction orthogonal to the first horizontal slit 35 or the second horizontal slit 45, the diameters of the holes 35h and 45h are set larger than the width of the first horizontal slit 35 or the second horizontal slit 45, and accordingly. The first horizontal slit 35 and the second horizontal slit 45 are observed as portions extending at the holes 35h and 45h at both ends thereof.

  As described above, when the holes 35h and 45h are formed in the both ends of the first horizontal slit 35 and the both ends of the second horizontal slit 45 so as to form an arc shape protruding outward toward the outside, Even if a force that widens the horizontal slit 35 and the second horizontal slit 45 is applied, the force is distributed at the arc edges of the holes 35h and 45h. For this reason, the ends of the first horizontal slit 35 and the second horizontal slit 45 are difficult to tear.

  The holes 35h and 45h may be formed in one of the first horizontal slit 35 and the second horizontal slit 45. The holes 35h and 45h may be formed only at one end of the first horizontal slit 35, or may be formed only at one end of the second horizontal slit 45. Even in these cases, at the portions where the holes 35h and 45h are formed, the ends of the first horizontal slit 35 and the second horizontal slit 45 are difficult to tear.

  A hole 49h similar to the holes 35h and 45h is also formed at the end of the auxiliary horizontal slit 49.

  In the electric wire protection sheet 230 according to the second modification shown in FIG. 6, the distal end portion 239 of each portion divided by the plurality of first vertical slits 34 in the first end portion 33 gradually becomes wider toward the distal end side. It is formed into a narrowing shape. Here, the tip end portion 239 in the middle portion of the first end portion 33 is formed in an isosceles triangle shape, and the tip end portions 239 on both sides of the first end portion 33 are in an isosceles triangle shape. It is formed in a half shape.

  Similarly, the tip end portion 249 of each portion divided by the plurality of second vertical slits 44 in the second end portion 43 is formed in a shape that gradually becomes narrower toward the tip end side. Here, the tip end portion 249 at the intermediate portion of the second end portion 43 is formed in an isosceles triangle shape, and the tip end portions 249 on both sides of the second end portion 43 have an isosceles triangle shape. It is formed in a half shape.

  According to this example, the front end portion 239 of each portion divided by the plurality of first vertical slits 34 in the first end portion 33 is arranged between the second vertical slits 44 of the second end portion 43 or in any row. It is easy to pass through the two horizontal slits 45. Similarly, the front end portion 249 of each portion divided by the plurality of second vertical slits 44 in the second end portion 43 can be easily passed between the first vertical slits 34 of the first end portion 33 or the first horizontal slit 35. . For this reason, the 1st end part 33 and the 2nd end part of electric wire protection sheet 230 can be united easily.

  In this modification, the first vertical slit 234 corresponding to the first vertical slit 34 is formed in a triangular slit shape that gradually spreads toward the tip side, and the second vertical slit 244 corresponding to the second vertical slit 44. The tip of each is formed in a triangular slit shape that gradually spreads toward the tip.

  In the wire protection sheet 330 according to the third modification shown in FIG. 7, the distal end portion 339 of each portion divided by the plurality of first vertical slits 34 in the first end portion 33 gradually becomes wider toward the distal end side. It is formed into a narrowing shape. Here, the front end portion 339 of the intermediate portion of the first end portion 33 is formed in a semi-elliptical shape, and the front end portions on both sides of the first end portion 33 are formed in a shape that further halves the semi-elliptical shape. Is done.

  Similarly, the tip part 349 of each part divided by the plurality of second vertical slits 44 in the second end part 43 is formed in a shape that gradually becomes narrower toward the tip side. Here, the distal end portion 349 of the intermediate portion of the second end portion 43 is formed in a semi-elliptical shape, and the distal end portions on both sides of the second end portion 43 are formed in a shape that halves the semi-elliptical shape. ing.

  Also according to this example, the first end portion 33 and the second end portion of the wire protection sheet 330 can be easily combined as in the second modified example.

  In this modification, the first vertical slit 334 corresponding to the first vertical slit 34 is formed in a slit shape gradually spreading in an arc shape toward the tip side, and the second vertical slit corresponding to the second vertical slit 44. The distal end portion of 344 is formed in a slit shape that gradually expands in an arc shape toward the distal end side.

  Moreover, in the electric wire protection sheet 430 which concerns on the 4th modification shown in FIG. 8, it respond | corresponds to each of the 1st vertical slit 34, the 1st horizontal slit 35, the 2nd vertical slit 44, and the 2nd horizontal slit 45 in the said embodiment. The first vertical slit 434, the first horizontal slit 435, the second vertical slit 444, and the second horizontal slit 445 are formed in a slit shape having a width. The widths of the first vertical slit 434, the first horizontal slit 435, the second vertical slit 444, and the second horizontal slit 445 can be, for example, approximately the same as the thickness of the wire protection sheet.

  According to this example, each portion of the first end 33 divided by the plurality of first vertical slits 434 is divided between the second vertical slits 444 of the second end 443 or the second horizontal slits 445 in any row. Easy to pass through. Similarly, each portion of the second end portion 443 divided by the plurality of second vertical slits 444 can be easily passed between the first vertical slits 434 of the first end portion 433 or the first horizontal slit 435. For this reason, the 1st end part 33 and the 2nd end part of electric wire protection sheet 230 can be united easily.

  In this modification, it is not necessary that all of the first vertical slit 434, the first horizontal slit 435, the second vertical slit 444, and the second horizontal slit 445 are formed in a slit shape having a width, and a part thereof is Similarly to the above-described embodiment, the slits may be formed in the same manner as the first vertical slit 34, the first horizontal slit 35, the second vertical slit 44, or the second horizontal slit 45.

  The auxiliary horizontal slit 449 corresponding to the auxiliary horizontal slit 49 is also formed in a slit shape having a width.

  In addition, each structure demonstrated in the said embodiment and each modification can be suitably combined unless it mutually contradicts.

  As described above, the present invention has been described in detail. However, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention.
