Description

[Technical Field]

[0001] The present disclosure relates to a protector and a wire harness with a protector. [Background technology]

[0002] Patent document 1 discloses that a positioning portion for positioning the head of the tie band is provided on the wall of the protector, and that an elastic leg portion is provided next to the positioning portion on the wall so as to protrude toward the positioning portion and in a direction away from the wall than the positioning portion.

[0003] According to Patent Document 1, when the tip of the band inserted into the head of the tie band and protruding from the head is cut off leaving a predetermined length of cutoff, the leg is elastically deformed so as to displace toward the positioning part. After cutting off, the leg returns to its original position due to its own elasticity, displacing the leg away from the positioning part. This makes it less likely that the cutoff part of the band will come into contact with the worker or other parts. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2020-28157 Summary of the Invention [Problem to be solved by the invention]

[0005] However, according to the technology disclosed in Patent Document 1, the size of the protector increases by the size of the leg portion. It is desired to make the protector smaller while protecting the cut margin of the tie band.

[0006] Therefore, an object of the present disclosure is to reduce the size of the protector while protecting the cut margin of the tie band. [Means for solving the problem]

[0007] The protector disclosed herein comprises a protector main body including a fixing plate portion arranged along a wire harness, a head accommodating portion having an accommodating space for accommodating the head of a tie band, and a cutout protection portion for protecting the cutout of the band portion of the tie band, wherein the head accommodating portion has an inner opening that opens to the inside of the fixing plate portion and an outer opening that opens to the outside of the fixing plate portion, and positions the head in the thickness direction of the fixing plate portion within the accommodating space, and the cutout protection portion includes a pair of protective walls extending from the outer opening to the outside of the fixing plate portion.

[0008] The wire harness with protector of the present disclosure also includes the protector, a wire harness arranged along the fixing plate portion, a head, and a tie band having a band portion extending from the head, the band portion being inserted into the head to engage and hold the band portion to the head, wherein the band portion extends from the head accommodated in the head accommodating portion, and when the band portion is wound around the fixing plate portion and the wire harness, it is engaged and held to the head through the inner opening, and the band portion extending through the head is positioned between the pair of protective walls through the outer opening.

[0011] [Description of the embodiments of the present disclosure] First, embodiments of the present disclosure will be listed and described.

[0012] The protector of the present disclosure is as follows.

[0013] (1) A protector comprising: a protector body including a fixing plate portion arranged along a wire harness; a head accommodating portion having an accommodating space for accommodating the head of a tie band; and a cut-off protection portion for protecting the cut-off of the band portion of the tie band, wherein the head accommodating portion has an inner opening that opens to the inside of the fixing plate portion and an outer opening that opens to the outside of the fixing plate portion, and positions the head in the thickness direction of the fixing plate portion within the accommodating space; and the cut-off protection portion includes a pair of protective walls extending from the outer opening to the outside of the fixing plate portion.

[0014] According to the present disclosure, the band portion of the tie band can be wrapped around the fixing plate portion and the wire harness, and the head portion of the tie band can be accommodated in the head accommodation portion. The band portion can also be passed through the inner opening, the head portion, and the outer opening. The portion of the band portion extending from the head portion can be left uncut and placed between a pair of protective walls. This protects the cut margin of the tie band. Furthermore, the pair of protective walls can be more easily miniaturized than a configuration in which the cut margin is protected by elastic legs. This allows the protector to be miniaturized.

[0015] (2) In the protector of (1), the storage space may extend in a direction intersecting the extension direction of the wire harness, the outer opening and the inner opening may be formed in an elongated shape along the extension direction of the storage space, and the pair of protective walls may be formed in a shape extending along the extension direction of the storage space.

[0016] This allows the position of the head in the accommodation space and the position where the band passes through the outer opening and inner opening to be adjusted according to the thickness of the wire harness. Also, even if the position of the cut margin of the band varies according to the thickness of the wire harness, the pair of protective walls can protect the cut margin of the band. Therefore, it is easy to accommodate different thicknesses of wire harnesses.

[0017] (3) In the protector of (1) or (2), the accommodation space may be set to a size that allows movement of the head in the thickness direction of the fixing plate portion.

[0018] In this case, the band portion can be pulled to move the head toward the outer opening, and then cut. When the pulling force on the band portion is then released, the elastic force of the wire harness allows the head to move toward the inner opening. This makes it easier for the cut edge of the band portion to be positioned within the pair of protective walls. This ensures more reliable protection of the cut edge of the tie band.

[0019] (4) A protector according to any one of (1) to (3), wherein the protector body includes a bottom plate portion and a fixing plate portion connected to one side edge of the bottom plate portion, the head storage portion has a bottom portion located on the bottom plate portion side of the storage space and has a setting opening on the opposite side of the bottom portion that allows the head portion to be set, the bottom portion has a passage hole through which the band portion extending from the head portion can pass, and the bottom plate portion may have a band passage groove formed in it that extends from the other side edge of the bottom plate portion toward the middle of the width of the bottom plate portion.

[0020] In this case, the head is accommodated in the head accommodation portion, and the band portion extending from the head can be guided into the protector through the passage hole and the band passing groove. The band portion can pass outside the wire harness disposed between the bottom plate portion and the fixed plate portion, through the inner opening, the head in the head accommodation portion, and then extend outside through the outer opening. Because the band portion passes through the band passing groove, it is easy to accommodate wire harnesses of different thicknesses. Furthermore, when the tie band is tightly tightened to fasten the wire harness, the band portion passes through a position in the band passing groove close to the fixed plate portion. When the force exerted on the tie band is released, the elastic restoring force of the wire harness causes the band portion to pass through a position in the band passing groove farther from the fixed plate portion, and the head moves toward the inner opening. This makes it easier for the cutting edge to be positioned within the pair of protective walls, thereby more reliably protecting the cutting edge.

[0021] (5) In the protector according to any one of (1) to (4), the distance between the pair of protective walls may be narrower than the width of the accommodation space.

[0022] This makes it difficult for the head to move from the accommodation space toward the pair of protective walls, and also makes it possible to more effectively protect the cutting margin.

[0023] (6) In the protector according to any one of (1) to (5), the distance between the pair of protective walls may be 10 mm or less.

[0024] This makes it difficult for fingers to get inside the pair of protective walls, and the cutting margin can be protected more effectively.

[0025] The protector-equipped wire harness of the present disclosure is as follows.

[0026] (7) A wire harness with a protector comprising any one of the protectors (1) to (6), a wire harness arranged along the fixing plate portion, a head, and a tie band having a band portion extending from the head, the band portion being inserted into the head to engage and hold the band portion on the head, wherein the band portion extends from the head accommodated in the head accommodating portion, and when the band portion is wound around the fixing plate portion and the wire harness, it is engaged and held on the head through the inner opening, and the band portion extending through the head passes through the outer opening and is arranged between the pair of protective walls.

[0027] This makes it possible to protect the cut margin of the tie band, and also makes it possible to miniaturize the wire harness with protector by using a miniaturized protector.

[0028] (8) In the protector-equipped wire harness of (7), the end of the band portion may be positioned on an extension of or inside the outward facing surfaces of the pair of protective walls.

[0029] This prevents the end of the band from protruding outside the pair of protective walls, thereby more effectively protecting the cutting margin.

[0030] [Details of the embodiments of the present disclosure] Specific examples of the protector and the wire harness with the protector of the present disclosure will be described below with reference to the drawings. Note that the present disclosure is not limited to these examples, but is defined by the claims, and is intended to include all modifications within the meaning and scope of the claims.

[0031] [Embodiment] A protector and a wire harness with a protector according to an embodiment will be described below. Fig. 1 is a perspective view showing a wire harness with a protector 10. Fig. 1 shows a part of a vehicle body B to which the wire harness with a protector 10 is to be attached. Also, in Fig. 1, a wire harness 20 is shown by a two-dot chain line.

[0032] <Overall structure> The protector-equipped wire harness 10 includes a protector 30, a wire harness 20, and a tie band 60.

[0033] The protector 30 is made of resin or the like, and is configured to be able to accommodate the wire harness 20 therein.

[0034] The protector 30 includes a protector body 32. The protector body 32 includes a fixing plate portion 40. The fixing plate portion 40 is disposed along the wire harness 20. The fixing plate portion 40 protects the wire harness 20.

[0035] In this embodiment, the protector main body 32 includes a bottom plate portion 33, a fixing plate portion 40, and an opposite plate portion 34. The bottom plate portion 33 is formed in the shape of an elongated plate that follows the routing path of the wire harness 20. The fixing plate portion 40 is continuous with one side edge of the bottom plate portion 33. The fixing plate portion 40 rises from one side edge of the bottom plate portion 33, and the opposite plate portion 34 rises from the other side edge of the bottom plate portion 33. The fixing plate portion 40 and the opposite plate portion 34 function as a pair of side walls that form a storage space for the wire harness 20 on one main surface side of the bottom plate portion 33.

[0036] The wire harness 20 is housed in a space surrounded by the bottom plate 33, the fixing plate 40, and the opposite plate 34. This protects the wire harness 20 from three directions while it is aligned along a fixed path. The fixing plate 40 is used to bundle and fix the wire harness 20 within the protector 30.

[0037] The protector 30 has a locking protrusion 36 that is locked and fixed to the body B (see FIGS. 2 and 3). The locking protrusion 36 may be provided on a protruding piece 35 that protrudes outward from the protector main body 32, or may be provided on the outward surface of the bottom plate portion 33. The locking protrusion 36 is locked into a locking hole formed in the body B, thereby attaching the protector 30 to the body.

[0038] The opening of the protector 30 on the opposite side to the bottom plate portion 33 may be closed by a lid portion 38 .

[0039] The wire harness 20 is a wiring member including at least one electric wire. For example, the wire harness 20 is configured by bundling a plurality of electric wires. The wire harness 20 is a component that connects electrical components in a vehicle.

[0040] A longitudinal portion of the wire harness 20 is housed in the protector 30. Both ends of the wire harness 20 extend outward from both ends of the protector 30.

[0041] The tie band 60 is a component that fastens the wire harness 20 to the protector 30. The tie band 60 keeps the wire harness 20 housed within the protector 30.

[0042] In this embodiment, the wire harness 20 is bound and fixed by tie bands 60 at both ends of the protector 30. The number of locations where the tie band 60 is used for binding and fixing may be at least one. The location where the tie band 60 is used for fixing may be a middle portion of the protector 30 in the longitudinal direction.

[0043] Focusing on one end of the protector 30, the configuration for binding and fixing the wire harness 20 and the protector 30 by the tie band 60 will be described.

[0044] <About the binding points of the protector> Fig. 2 is a perspective view of one end of protector 30 as seen obliquely from above, and Fig. 3 is a perspective view of one end of protector 30 as seen obliquely from below. Fig. 4 is a plan view showing one end of protector 30. Fig. 5 is a partially enlarged view of Fig. 4. Fig. 6 is a cross-sectional view taken along line VI-VI in Fig. 4.

[0045] 1 to 6, the protector 30 is a component that is integrally molded from resin or the like using a mold. The protector may also be a component that is a combination of multiple components.

[0046] The protector 30 includes the protector main body 32, a head accommodating portion 41, and a cut-off protection portion 50. The head accommodating portion 41 is a portion that accommodates the head 62 of the tie band 60. The cut-off protection portion 50 is a portion that protects the cut-off 66a of the band portion 66 of the tie band 60.

[0047] The wire harness 20 is bound and fixed to the protector body 32 using a tie band 60 at a position where the head accommodating portion 41 and the cut margin protecting portion 50 are provided.

[0048] Here, we will explain about tie band 60.

[0049] The tie band 60 is a resin part having a head portion 62 and a band portion 66 .

[0050] The head 62 is formed so as to be able to lock and hold the longitudinal middle portion of the band portion 66. For example, an insertion hole 63h through which the band portion 66 can be inserted is formed in the head 62. Locking claws 63p that can be selectively locked into a plurality of locking recesses of the band portion 66 are formed inside the insertion hole 63h.

[0051] The band portion 66 is a strip-shaped portion extending from the head portion 62. A plurality of locking recesses are formed on one main surface of the band portion 66. The plurality of locking recesses are aligned along the direction in which the band portion 66 extends.

[0052] Then, the band portion 66 is deformed into a ring shape and passed through the insertion hole 63h, and the tip of the band portion 66 is pulled. When this is done, the locking claws 63p lock into the locking recesses at any position on the band portion 66 at a position corresponding to the pulling force. As a result, the middle portion of the band portion 66 in the longitudinal direction is locked and held by the head 62.

[0053] With the wire harness 20 arranged along the fixing plate 40, the band 66 is wound around the fixing plate 40 of the protector body 32 and the wire harness 20. Then, the band 66 is engaged and held by the head 62, whereby the wire harness 20 is bound and fixed to the fixing plate 40.

[0054] The tie band 60 may be a part called a cable tie.

[0055] If the portion of the band portion 66 that passes through the insertion hole 63h extends too far, it may become a hindrance, and therefore the end of the band portion 66 may be cut off and removed. However, if the band portion 66 is cut at the exit of the insertion hole 63h, even a slight pull in the direction of removal from the head 62 may cause the band portion 66 to be removed from the head 62. For this reason, it is preferable to cut off the end of the band portion 66 at a position away from the exit of the insertion hole 63h. As a result of cutting the end of the band portion 66 at a position a predetermined distance away from the exit of the insertion hole 63h, the end of the band portion 66 extends a predetermined distance from the insertion hole 63h, and its tip end has a portion that is a cut cross section. This portion is the cut margin 66a of the band portion 66.

[0056] The head accommodation portion 41 is a portion provided on the fixing plate portion 40 and has an accommodation space 45, an inner opening 43h, and an outer opening 44h. The head 62 is accommodated in the accommodation space 45. The inner opening 43h opens to the inner opening 43h of the fixing plate portion 40, and the outer opening 44h opens to the outside of the fixing plate portion 40. The inner opening 43h and the outer opening 44h open toward the accommodation space 45. When viewed along the thickness direction of the fixing plate portion 40, it is preferable that the inner opening 43h and the outer opening 44h extend in an overlapping range.

[0057] Then, with the head 62 accommodated in the accommodation space 45, the band portion 66 passes through the inner opening 43h and is inserted into the head 62 in the accommodation space 45. Furthermore, after passing through the head 62 in the accommodation space 45, the band portion 66 can extend out of the head accommodation portion 41 through the outer opening 44h.

[0058] Furthermore, the accommodation space 45 narrows on the inner opening 43h and outer opening 44h sides, and the head 62 can be positioned within the accommodation space 45 in the thickness direction of the fixing plate portion 40.

[0059] More specifically, the head receiving portion 41 has a pair of receiving walls 42 , an inner wall 43 , and a pair of narrowing protrusions 44 .

[0060] The inner wall 43 is continuously connected to the fixing plate portion 40. The inner opening 43h is formed in the inner wall 43. The width W5 of the inner opening 43h is smaller than the width W1 of the storage space 45 and smaller than the width W2 of the head portion 62. The width W5 of the inner opening 43h is the same as or larger than the width W4 of the band portion 66.

[0061] Each of the pair of storage walls 42 protrudes outward from the inner wall 43. The inner opening 43h is located between the pair of storage walls 42. The pair of storage walls 42 are parallel to each other, and a storage space 45 is formed therebetween in which the head 62 can be placed. The distance between the pair of storage walls 42 is the width W1 of the storage space 45, which is the same as or larger than the width W2 of the head 62. The protruding length of the pair of storage walls 42 is the same as or larger than the dimension of the head 62 in the direction in which the insertion hole 63h extends. Therefore, the head 62 can be accommodated in the storage space 45 formed between the pair of storage walls 42.

[0062] The pair of narrowing protrusions 44 protrude inward from the tip ends of the pair of storage walls 42. The tip ends of the pair of narrowing protrusions 44 face each other. An outer opening 44h is formed between the pair of narrowing protrusions 44. The width W6 of the outer opening 44h is smaller than the width W1 of the storage space 45 and smaller than the width W2 of the head 62. The width W6 of the outer opening 44h is the same as or larger than the width W4 of the band portion 66.

[0063] The head portion 62 is positioned between the inner wall 43 and the pair of narrowing protrusions 44 in the thickness direction of the fixing plate portion 40 .

[0064] The cutting margin protection portion 50 includes a pair of protection walls 52 that extend from the outer opening 44h to the outside of the fixing plate portion 40. More specifically, a pair of protection walls 52 protrude outward from the respective tip ends of the pair of width-narrowing protrusions 44. The pair of protection walls 52 are parallel to each other. The distance W3 between the pair of protection walls 52 is the same as or greater than the width W4 of the band portion 66.

[0065] The cutout 66a of the band portion 66 that passes through the head 62 passes through the outer opening 44h and is disposed between the pair of protective walls 52. The distance W3 between the pair of protective walls 52 is preferably narrower than the width W1 of the accommodation space 45. The distance W3 between the pair of protective walls 52 is preferably 10 mm or less.

[0066] In order to accommodate different thicknesses of the wire harness 20, the head 62 may be configured to be able to be accommodated at any position in the direction intersecting with the wire harness 20.

[0067] In this embodiment, the pair of protective walls 52, the inner wall 43, and the pair of width-narrowing protrusions 44 are formed in an elongated shape in a direction intersecting the extension direction of the wire harness 20, i.e., along the width direction of the fixing plate portion 40. As a result, the accommodating space 45 is formed in a shape that extends in a direction intersecting the extension direction of the wire harness 20, i.e., along the width direction of the fixing plate portion 40.

[0068] This allows the head 62 to be accommodated at any position in a direction intersecting the extension direction of the wire harness 20. In other words, it can be said that the head 62 can be accommodated at any position by changing the distance from the bottom plate portion 33.

[0069] The pair of protective walls 52 are also formed in a shape that extends along the extension direction of the accommodation space 45. Therefore, no matter where the head 62 is accommodated along the extension direction of the accommodation space, the cutout 66a extending from the head 62 can be positioned between the pair of protective walls 52.

[0070] The accommodation space 45 is preferably sized to allow movement of the head 62 in the thickness direction of the fixing plate 40. In other words, the distance L1 between the inner wall 43 and the pair of narrowing protrusions 44 is preferably set larger than the dimension L2 of the head 62 in the extending direction of the insertion hole 63h (see FIG. 5). In this embodiment, the distance L1 is larger than the dimension L2 by a dimension D.

[0071] In this case, when cutting the band portion 66 with the cutting blade E, the tip of the band portion 66 can be pulled to position the head portion 62 closer to the outer opening 44h. In this state, the band portion 66 can be cut on the extension of the outlet end faces of the pair of protective walls 52 or very close to it.

[0072] After the band portion 66 is cut, the force pulling the tip of the band portion 66 is released. When the tip of the band portion 66 is pulled to move the head 62 toward the outer opening 44h, it is considered that the wire harness 20 is elastically deformed and pressed toward the fixing plate portion 40. When the force pulling the tip of the band portion 66 is released, the wire harness 20 attempts to return to its original shape, and the head 62 attempts to move away from the outer opening 44h. Then, the cut end surface of the cut margin 66a moves so as to retreat from the extension of the outlet end surfaces of the pair of protective walls 52. Therefore, the cut margin 66a is more reliably protected within the pair of protective walls 52.

[0073] In order to keep the head 62 housed within the head housing 41 during the bundling operation, etc., the head housing 41 may have a bottom 46 with a passage hole 46h and a setting opening 42h.

[0074] In this embodiment, the bottom portion 46 protrudes outward from the inner wall 43. The bottom portion 46 is located closer to the bottom plate portion 33 than the inner opening 43h. The bottom plate portion 33 may also be connected to the pair of storage walls 42. The bottom portion 46 is located closer to the bottom plate portion 33 than the storage space 45, and prevents the head portion 62 stored in the storage space 45 from escaping toward the bottom plate portion 33.

[0075] The bottom portion 46 is formed with a passage hole 46h through which the band portion 66 extending from the head portion 62 can pass. The head portion 62 is accommodated in the accommodation space 45 with the band portion 66 passing through the passage hole 46h.

[0076] The side of the pair of protective walls 52 opposite the bottom 46 is a setting opening 42h that allows the head 62 to be set. For example, the setting opening 42h has a width that is the same as or larger than the width of the head 62, and a length in the thickness direction of the fixing plate 40 that is the same as or larger than the length of the head 62.

[0077] A band passing groove 33g is formed in the bottom plate portion 33. The band passing groove 33g penetrates the inside and outside of the bottom plate portion 33, allowing the band portion 66 to pass through the inside and outside of the bottom plate portion 33. The band passing groove 33g is a long, narrow groove extending from the other side edge of the bottom plate portion 33 toward the center in the width direction of the bottom plate portion 33. The position at which the band portion 66 passes through the bottom plate portion 33 can be adjusted depending on the extent of the band passing groove 33g. For example, if the wire harness 20 is thick, the band portion 66 can pass through the band passing groove 33g at a position closer to the other side edge of the bottom plate portion 33. Furthermore, for example, if the wire harness 20 is thin, the band portion 66 can pass through the band passing groove 33g at a position closer to one side edge of the bottom plate portion 33.

[0078] The tie band 60 is wound around and fixed to the wire harness 20 and the fixing plate portion 40 as follows.

[0079] That is, the tie band 60 is prepared before the end is cut. The band portion 66 is passed through the accommodation space 45 and inserted into the through hole 46h of the bottom portion 46. Then, the head portion 62 is placed in the accommodation space 45 through the setting opening 42h. In this state, the head portion 62 can be placed at any position within the accommodation space 45 in its extending direction.

[0080] The band portion 66 passes over the outward surface of the bottom plate portion 33 and is guided into the protector body 32 through the band passage groove 33g.

[0081] The wire harness 20 is disposed in a space surrounded by the bottom plate 33, the fixing plate 40, and the opposite plate 34. The band 66 is wrapped around the wire harness 20 from the opposite side of the bottom plate 33 and the fixing plate 40. The band 66 further passes through the inner opening 43h and is inserted into the insertion hole 63h of the head 62. The portion of the band 66 that has exited the head 62 passes through the outer opening 44h and between the pair of protective walls 52. Before being cut, the band 66 extends outward from the pair of protective walls 52.

[0082] The portions of the band portion 66 that extend beyond the pair of protective walls 52 are cut and removed by the cutting blade E. The cutting locations are preferably on the extensions of the outward end faces of the pair of protective walls 52 or in the very vicinity thereof.

[0083] Since the cutout 66a of the band portion 66 is easily secured to have a length corresponding to the protruding length of the pair of protective walls 52, it is easy to secure the cutout 66a with a sufficient length to prevent slipping out.

[0084] Preferably, during cutting, the tip of the band portion 66 is pulled in a direction to be pulled out from the head portion 62. In this case, the wire harness 20 is pressed against the fixing plate portion 40 while elastically deforming. After the tip of the band portion 66 is cut, the force pulling the band portion 66 is released. Then, the wire harness 20 tries to return to its original shape, so the band portion 66 widens and the head portion 62 tries to move toward the inner opening 43h. This makes it easier for the cut end surface of the cut margin 66a to move to a position retracted from the tip surfaces of the pair of protective walls 52.

[0085] Furthermore, because the band portion 66 can pass through any position in the direction in which the band passing groove 33g extends, when the force that tightly fastens the tie band 60 is released, the elastic restoring force of the wire harness 20 causes the band portion 66 to change its state so that it passes through a position in the band passing groove 33g that is far from the fixing plate portion 40. This makes it easier for the head portion 62 to move toward the inner opening 43h. This also makes it easier for the cutouts 66a of the band portion 66 to be positioned so that they fit within the pair of protective walls 52. This allows the cutouts 66a of the tie band 60 to be more reliably protected.

[0086] After cutting, the band portion 66 extends from the head 62 accommodated in the head accommodation portion 41. This band portion 66, while wound around the fixing plate portion 40 and the wire harness 20, passes through the inner opening 43h, returns to the head 62, and is engaged and held by the head 62. The band portion 66 that extends through the head 62 passes through the outer opening 44h and is positioned between the pair of protective walls 52.

[0087] After the tie band 60 is cut, the ends of the band portions 66 are preferably positioned on the extensions of or inside the outward facing surfaces of the pair of protective walls 52 .

[0088] <Differences due to wire harness thickness> The difference between when the wire harness 20 is thick and when it is thin will be described.

[0089] The wire harness 20 shown in Fig. 6 is thicker than the wire harness 20B shown in Fig. 7. For example, the wire harness 20 shown in Fig. 6 includes a first electric wire bundle 21 and a second electric wire bundle 22. The wire harness 20B shown in Fig. 7 includes a first electric wire bundle 21B and a second electric wire bundle 22. The first electric wire bundle 21 closer to the fixing plate 40 is thicker than the first electric wire bundle 21B, and therefore the wire harness 20 is thicker than the wire harness 20B.

[0090] As shown in FIG. 6, when the wire harness 20 is thick, the band portion 66 passes through the inner opening 43h at a position away from the bottom plate portion 33, so that the head portion 62 is disposed near the setting opening 42h in the accommodation space 45. Also, as shown in FIG. 7, when the wire harness 20B is thin, the band portion 66 passes through the inner opening 43h at a position close to the bottom plate portion 33, so that the head portion 62 is disposed near the bottom portion 46 in the accommodation space 45. Therefore, the head portion 62 can be disposed at a position in the accommodation space 45 according to the thickness of the wire harness 20. If the wire harness 20B is thin, the head portion 62 can be brought close to the bottom plate portion 33, so that the band portion 66 can be brought close to the bottom plate portion 33. Therefore, even when the wire harness 20B is thin, the wire harness 20B can be held in the protector main body 32 while being pressed against the bottom plate portion 33, and rattle of the wire harness 20B is suppressed.

[0091] 6, when the wire harness 20 is thick, the band portion 66 can pass through the band passing groove 33g at a position close to the opposite plate portion 34. When the wire harness 20B is thin, the band portion 66 can pass through the band passing groove 33g at a position close to the fixing plate portion 40. Therefore, even if the wire harness 20B is thin, the wire harness 20B can be held in the protector main body 32 while being pressed against the fixing plate portion 40, and rattle of the wire harness 20B is suppressed.

[0092] The binding and fixing structure of the tie band 60 at the other end of the protector 30 may be the same as the above structure, or may be a different structure.

[0093] <Effects, etc.> According to the protector 30 and the protector-equipped wire harness 10 configured as described above, the band portion 66 of the tie band 60 can be wound around the fixing plate portion 40 and the wire harness 20, and the head portion 62 of the tie band 60 can be accommodated in the head portion accommodating portion 41. The band portion 66 can be passed through the inner opening 43h, the head portion 62, and the outer opening 44h. The portion of the band portion 66 extending from the head portion 62 can be left uncut and placed between the pair of protective walls 52. This protects the cutout 66a of the tie band 60. The pair of protective walls 52 can be made smaller than a configuration in which the cutout is protected by elastic legs. Therefore, the protector 30 can be made smaller. The protector-equipped wire harness 10 can be made smaller by making the protector 30 smaller.

[0094] Furthermore, because the cutting margin 66a is protected, when attaching the protector 30 to a vehicle, the worker can hold the protector 30 at any position. This improves the workability of attaching the protector 30.

[0095] Furthermore, the accommodating space 45 extends in a direction intersecting the extension direction of the wire harnesses 20, 20B, the outer opening 44h and the inner opening 43h are formed in an elongated shape along the extension direction of the accommodating space 45, and the pair of protective walls 52 are formed in a shape extending along the extension direction of the accommodating space 45. Therefore, the position of the head 62 in the accommodating space 45 and the position where the band portion 66 passes through the outer opening 44h and the inner opening 43h can be adjusted according to the thickness of the wire harnesses 20, 20B. Furthermore, even if the position of the cut margin of the band portion 66 varies according to the thickness of the wire harnesses 20, 20B, the cut margin 66a can be protected by the pair of protective walls 52. Therefore, it is possible to easily accommodate differences in thickness of the wire harnesses 20, 20B.

[0096] Furthermore, the accommodation space 45 is sized to allow movement of the head 62 in the thickness direction of the fixing plate 40. Therefore, the band 66 can be pulled to move the head 62 toward the outer opening 44h, and then cut. After this, when the force pulling the band 66 is released, the elastic force of the wire harness 20 allows the head to move toward the inner opening. This makes it easier for the cut margin 66a to be positioned so that it fits into the pair of protective walls 52. Therefore, the cut margin 66a of the tie band 60 can be more reliably protected.

[0097] The head accommodating portion 41 has a bottom portion 46 with a passage hole 46h and a mounting opening 42h. A band-passing groove 33g is formed in the bottom plate portion 33. The head 62 is accommodated in the head accommodating portion 41, and the band portion 66 extending from the head 62 can be guided into the protector 30 through the passage hole 46h and the band-passing groove 33g. The band portion 66 passes outside the wire harness 20 disposed between the bottom plate portion 33 and the fixing plate portion 40, passes through the inner opening 43h, the head 62 in the head accommodating portion 41, and then extends outward through the outer opening 44h. Because the band portion 66 passes through the band-passing groove 33g, it can easily accommodate different thicknesses of the wire harnesses 20, 20B. When the tie band 60 is tightly tightened to fasten the wire harness 20, the band portion 66 passes through a portion of the band-passing groove 33g close to the fixing plate portion 40. When the force tightening the tie band 60 is released, the elastic restoring force of the wire harness 20 causes the band portion 66 to pass through a position in the band passing groove 33g farther from the fixing plate portion 40, and the head portion 62 moves toward the inner opening 43h. This makes it easier for the cutout 66a to be positioned so that it fits inside the pair of protective walls 52. This more reliably protects the cutout 66a.

[0098] Furthermore, since the distance W3 between the pair of protective walls 52 is smaller than the width W3 of the accommodation space 45, the head 62 is less likely to move from the accommodation space 45 toward the pair of protective walls 52. Furthermore, the cutting margin 66a can be more effectively protected.

[0099] If the distance W3 between the pair of protective walls 52 is 10 mm or less, it is difficult for fingers to get inside the pair of protective walls 52, and the cutting margin 66a can be protected more effectively.

[0100] The end faces of the cutouts 66a are positioned on the extensions of or inward of the outward facing surfaces of the pair of protective walls 52, so that the cutouts 66a can be protected more effectively.

[0101] The configurations described in the above embodiment and modifications can be combined as appropriate as long as they are not mutually contradictory. [Explanation of symbols]
