Abstract
Description
[Technical Field]
[0001] The present invention relates to a housing, a protector, and an electrical junction box that house, for example, an elongated body or electronic components to be wired in a vehicle. [Background technology]
[0002] Vehicles are equipped with housings such as protectors that house elongated objects such as wire harnesses and tubes to protect the elongated objects and regulate the wiring direction, and electrical connection boxes that house boards with electronic components mounted thereon, terminals, etc. Such housings have an opening and are equipped with a housing section that houses the object to be housed inside, and a cover section that covers the opening of the housing section, and are sometimes configured by assembling the housing section and the cover section.
[0003] For example, Patent Document 1 discloses an example of the above-mentioned housing, which is a vehicle protector in which a main body portion having a concave cross section that accommodates a part of a wire harness and a lid portion that covers an opening of the main body portion are engaged and fixed. The vehicle protector disclosed in Patent Document 1 has a frame-shaped locked portion provided on a side surface of a main body portion, and a locking portion that protrudes toward the locked portion provided on a side surface of a lid portion. The locked portion and the locking portion are locked together by inserting the locking portion through the locked portion, and the lid portion can be locked and fixed in place in an assembled state to the main body portion.
[0004] In order to fasten the lid to the main body, the lid is brought close to the main body while aligning the positions of the engaging portion on the main body and the engaging portion on the lid, and then the engaging portion and the engaging portion are engaged.
[0005] Specifically, the locked portion and the locking portion are aligned, and the top plate of the lid is pressed against the main body. At this time, the force pressing the top plate acts on the locking portion as an external force that deforms the locked portion and inserts it through, thereby locking the locked portion and the locking portion together and fixing the lid to the main body. However, in the locking structure of the vehicle protector disclosed in Patent Document 1, there are cases where the force pressing the top plate portion of the lid portion toward the main body portion cannot be sufficiently applied to the locked portion.
[0006] For example, when a wire harness is routed by bending it downward, the top plate portion of the lid may be inclined to avoid the separate component located above the routing path in order to prevent unintended interference between the vehicle protector and the separate component.
[0007] In such a lid, the top plate portion directly above the locking portion is inclined, so there is a risk that the force pressing the top plate portion of the lid toward the main body portion may not act sufficiently as an external force to lock the locked portion and the locking portion together.
[0008] In detail, with such a lid portion, even if the inclined portion directly above the locking portion or a portion different from the inclined portion is pressed toward the main body portion, the pressing force cannot be applied directly to the locking portion, and there is a risk that the locked portion and the locking portion will not be able to be locked together.
[0009] Thus, in a housing such as a vehicle protector equipped with the locking structure disclosed in Patent Document 1, depending on the shape of the lid portion, the force pressing the lid portion may not be sufficiently applied to the locking portion, and there is a risk that the main body portion and the lid portion may not be locked and fixed.

[0010] [Patent Document 1] Japanese Patent Application Publication No. 2023-116180 Summary of the Invention [Problem to be solved by the invention]
[0011] In view of the above-mentioned problems, the present invention aims to provide a housing, a protector, and an electrical connection box that can reliably engage a locking portion with a locked portion, regardless of the shapes of the main body portion and the cover portion, and that can assemble and lock the main body portion and the cover portion together. [Means for solving the problem]
[0012] This invention is characterized in that it comprises a main body portion having an opening and accommodating at least a part of a contained object, a cover portion covering at least a part of the opening of the main body portion, and a locking and fixing portion that locks and fixes the cover portion in an assembled state with the cover portion assembled to the main body portion, wherein the direction in which the main body portion and the cover portion are assembled is defined as an assembly direction, and the locking and fixing portion comprises a locking portion provided on at least one of the main body portion and the cover portion, and a locked portion provided on at least the other and with which the locking portion locks, the locking portion protrudes toward the locked portion along the assembly direction, and the cover portion is provided with a locking operation portion that protrudes in a direction intersecting the assembly direction and outward, and performs a locking operation to lock the locked portion and the locking portion, and the direction in which the locking operation portion protrudes from the cover portion and a direction perpendicular to the assembly direction are defined as an orthogonal direction, and the locking operation portion is arranged so as to straddle the center of the orthogonal direction of the locking portion in the orthogonal direction.
[0013] The present invention is also characterized in that the object to be accommodated in the housing is an elongated body, the main body is a protector main body, and the cover is a protector cover. The present invention is also characterized in that the object to be accommodated in the housing is an electronic component, the main body is a lower cover, and the cover is an upper cover, making it an electrical junction box.
[0014] The object to be accommodated includes a long body such as a wire harness or a tube, and an electronic component that is electrically connected to a board provided inside the accommodation portion. The wire harness includes not only a bundle of insulated electric wires formed by bundling a plurality of insulated electric wires, or a single insulated electric wire, but also a communication cable such as an optical fiber cable for transmitting information, or a bundle of communication cables.
[0015] The tube also includes a hose through which a fluid such as washer fluid or cooling water flows, a corrugated tube through which the wire harness is inserted, and a single corrugated tube. The electronic components are the circuit body provided in the main body portion and components electrically connected to the circuit body, including terminals for connecting a connector from the outside, and relays and fuses that are attached to the main body portion or cover portion and electrically connected to the circuit body.
[0016] The main body and the cover may be formed separately, or may be integrally connected to each other so as to be openable and closable. The main body and the cover being integrally connected includes the main body and the cover being connected to each other by a hinge so as to be openable and closable.
[0017] The locking and fixing portion may be provided on the main body portion and the cover portion, respectively, so long as the locking portion and the locked portion form a pair and can be locked and fixed, and the locked portion may be provided on the main body portion and the locking portion may be provided on the cover portion, or vice versa. Also, the locking portion and the locked portion may be provided at different positions on the main body portion, and the locked portion and the locking portion may be provided on the cover portion at positions corresponding to the locking portion and the locked portion provided on the main body portion.
[0018] The aforementioned "protruding outward in a direction intersecting the assembly direction" includes not only the locking operation portion protruding in a direction perpendicular to the assembly direction, but also the locking operation portion protruding at an angle relative to the assembly direction rather than in the perpendicular direction. The locking operation refers to applying an external force to the locking operation portion in a direction toward the main body portion along the assembly direction by the fingers of a worker performing the assembly work, a jig of an assembly device, etc. Note that the external force may be applied to the locking operation portion in a direction toward the main body portion along the assembly direction while pressing a location other than the locking operation portion, such as the cover portion, toward the main body portion along the assembly direction.
[0019] According to this invention, regardless of the shapes of the main body and the cover, the locking portion and the locked portion can be securely locked together, thereby locking and fixing the main body and the cover together. In detail, the main body part and the cover part are brought closer together in the assembly direction while aligning the positions of the locking portion and the locked portion provided in the locking fixing part, and by performing a locking operation on the locking operating part, the locking portion and the locked portion are locked together, thereby locking and fixing the main body part and the cover part together.
[0020] Specifically, by aligning the positions of the locked portion and the locking portion and performing a locking operation on the locking operation portion provided on the cover portion, an external force can be applied to one of the locking portion and the locked portion provided on the cover portion in the assembly direction toward the main body portion. This allows at least one of the locking portion and the locked portion to be deformed and moved to a locking position where the locking portion and the locked portion are locked, thereby locking the locking portion and the locked portion together.
[0021] Furthermore, since the locking operation portion is positioned so as to straddle the center of the locking portion in the orthogonal direction, the external force applied by the locking operation can be applied directly and efficiently to the locking portion protruding in the assembly direction, and the locking operation can reliably lock the locking portion and the locked portion together.
[0022] Therefore, since a locking operation portion is provided in the cover portion, regardless of the shapes of the main body portion and the cover portion, the locking portion and the locked portion can be securely locked together by performing a locking operation on the locking operation portion, and the main body portion and the cover portion can be assembled and locked.
[0023] In one aspect of this invention, the locking operation portion is formed in a plate shape having a predetermined length in the orthogonal direction, the cover portion has a cover side wall portion extending in the assembly direction, and the locking operation portion and at least one of the locking portion and the locked portion are provided on the cover side wall portion, and an operation connecting portion is provided that connects the main surface of the locking operation portion formed in a plate shape to the cover side wall portion.
[0024] This invention allows the locking operation to be performed on the main surface of the locking operation portion that intersects with the assembly direction, making the locking operation easy. Furthermore, the operation connecting portion that connects the protruding locking operation portion to the cover side wall portion improves the rigidity of the locking operation portion. This allows the external force applied to the locking operation portion to be used efficiently as an external force that locks the locking portion and the locked portion. In other words, the locking operation allows the locking portion and the locked portion to be more reliably locked together.
[0025] As another aspect of the present invention, the operation connecting portion may be disposed on both ends of the locking operation portion in the orthogonal direction. According to this invention, the rigidity of the locking operation part is improved by the operation connecting parts arranged on both ends in the perpendicular direction, while the locking operation can be performed using the central part of the locking operation part in the perpendicular direction, thereby improving the locking operability.
[0026] As a further aspect of the present invention, an operation anti-slip portion for preventing slippage during the locking operation may be provided on one of the two main surfaces of the locking operation portion opposite to the main body portion. According to this invention, the fingers or a jig of the worker performing the locking operation can be prevented from slipping off the locking operation portion, and the locking operation can be performed reliably.
[0027] The operation slip prevention portion may be a protrusion protruding from the locking operation portion, or may be formed by attaching a separate member with a high friction coefficient, such as rubber. The protrusion may include a single or multiple ribs extending in the perpendicular direction at the tip side of the locking operation portion, a zigzag rib extending in the same direction, or multiple projections protruding from the locking operation portion.
[0028] As another aspect of the present invention, the main body may be provided with an operation assisting portion that assists the locking operation, and the operation assisting portion may be disposed at a position corresponding to the locking operation portion in the orthogonal direction. The above-mentioned operation assisting part being positioned at a position corresponding to the locking operation part in the orthogonal direction means that in the orthogonal direction, at least a portion of the locking operation part and the operation assisting part are positioned so as to face each other in the assembly direction.
[0029] According to this invention, the locking operation can be assisted by the operation assisting part provided at a position corresponding to the locking operation part. That is, the locking operation can be performed by sandwiching the locking operation part provided on the cover part and the operation assisting part provided on the main body part along the assembly direction, thereby improving the workability of the locking operation. Alternatively, a locking operation can be performed on the locking operation portion while using the operation assisting portion as a fulcrum, and an external force can be easily applied to the locking operation portion in the assembly direction.
[0030] As another aspect of the present invention, the locking operation portion and the operation auxiliary portion may be formed in the shape of plates having a predetermined length in the orthogonal direction, and at least a portion of each may face each other in the assembly direction. According to this invention, in both the locking operation section and the operation assistance section, the main surfaces that intersect with the assembly direction can be used to perform the locking operation by sandwiching the locking operation section and the operation assistance section, thereby further improving the workability of the locking operation.
[0031] In another aspect of the present invention, the locking portion is provided on the cover portion, and the locked portion is provided on the main body portion, the locked portion protrudes in the direction in which the locking operation portion protrudes, and is formed in a frame shape into which the locking portion can be inserted, and the locked portion and the operation assistance portion may be configured as a single unit.
[0032] This invention improves the rigidity of the operation auxiliary part that is integral with the locked part, and suppresses deformation of the operation auxiliary part when performing a locking operation in which the locking operation part and the operation auxiliary part are sandwiched between them. Therefore, the external force applied by the locking operation can be reliably applied as an external force that inserts the locking part into the locked part while deforming at least one of the locking part and the locked part, thereby reliably locking the locking part and the locked part. Furthermore, by integrally configuring the locked part and the operation auxiliary part, it is possible to save space in the housing and simplify the structure.
[0033] In another aspect of the present invention, the operation assisting portion may have a through hole portion formed therein that penetrates in the assembly direction, and the through hole portion may be provided near the point where the engaging portion engages with the engaged portion. With this invention, when engaging the engaging portion and the engaged portion, the engaging portion can be easily inserted into the engaged portion by deforming the area near the through-hole portion in the engaged portion, and the engaging portion and the engaged portion can be easily engaged with each other.
[0034] In another aspect of the present invention, the main body portion has a main body side wall portion extending in the assembly direction, and the main body side wall portion is provided with the locking portion and the operation auxiliary portion, and an auxiliary connecting portion is provided that connects the main surface of both main surfaces of the operation auxiliary portion opposite the cover portion to at least one of the main body side wall portion and the locking portion, and the cover portion has a cover side wall portion extending in the assembly direction, and the locking portion and the locking operation portion are provided on the cover side wall, and an operation connecting portion is provided that connects the main surface of both main surfaces of the locking operation portion opposite the main body portion to the cover side wall.
[0035] According to this invention, the auxiliary connecting portion connecting the operation auxiliary portion to at least one of the main body side wall portion and the locked portion can improve the rigidity of the operation auxiliary portion, and the operating connecting portion connecting the cover side wall portion and the locking operating portion can improve the rigidity of the locking operating portion. This allows the external force applied to the locking operating portion and the operation auxiliary portion to be used efficiently as an external force that locks the locking portion and the locked portion. In other words, the locking operation can more reliably lock the locking portion and the locked portion.
[0036] In addition, since the auxiliary connecting portion is provided on the main surface of the operation assisting portion opposite the cover portion, and the operation connecting portion is provided on the main surface of the locking operation portion opposite the main body portion, the locking operation portion and the operation assisting portion can be provided close to each other along the assembly direction, improving the operability of the locking operation. Furthermore, unintentional interference between the auxiliary connecting portion and the operation connecting portion can be prevented when locking the locked portion and the locking portion.
[0037] As another aspect of the present invention, the operation connecting portion may be disposed on both ends of the locking operation portion in the orthogonal direction. With this invention, the rigidity of the locking operation part is improved by the operation connecting parts arranged on both ends in the perpendicular direction, while the locking operation can be performed by utilizing the central part of the locking operation part in the perpendicular direction, making the locking operation easy to perform.
[0038] In another aspect of the present invention, the auxiliary connecting portions may be arranged on both ends of the operation auxiliary portion in the orthogonal direction. According to this invention, the auxiliary connecting portions arranged on both ends in the perpendicular direction improve the rigidity of the operation auxiliary portion, while the locking operation can be performed by utilizing the central portion of the operation auxiliary portion in the perpendicular direction, making the locking operation easy to perform.
[0039] In another aspect of the present invention, the operation connecting portion may be arranged at both ends of the locking operation portion in the orthogonal direction, and the auxiliary connecting portion may be arranged at both ends of the operation auxiliary portion in the orthogonal direction. With this invention, the operating connection portion and auxiliary connection portion arranged on both ends in the perpendicular direction improve the rigidity of the locking operating portion and the operating auxiliary portion, while allowing the locking operation to be performed using the central portion in the perpendicular direction of the locking operating portion and the operating auxiliary portion, making the locking operation easy.
[0040] In another aspect of the present invention, an operation anti-slip portion for preventing slippage during the locking operation may be provided on at least one of the main surfaces of the locking operation portion opposite the main body portion and the main surfaces of the operation auxiliary portion opposite the cover portion. According to this invention, the fingers or tool of the operator performing the locking operation can be prevented from slipping off from at least one of the locking operation portion and the operation auxiliary portion, and the locking operation can be performed reliably. [Effects of the Invention]
[0041] This invention makes it possible to provide a housing, a protector, and an electrical connection box that can reliably engage the locking portion with the locked portion, regardless of the shapes of the main body portion and the cover portion, and that can assemble and lock the main body portion and the cover portion together.

In FIG. 1, the right side along the longitudinal direction X is referred to as the right side XR, and the left side is referred to as the left side XL. Similarly, the right side along the short-side direction Y is referred to as the front side YF, and the left side is referred to as the back side YB. The upper side along the up-down direction Z is referred to as the upper side ZU, and the lower side is referred to as the lower side ZD. This direction also applies to FIGS. 2, 3, 5, 7 and 8.
[0051] 4, 6, and 9, the direction in which the locked portion 24 protrudes from the main body side wall portion 25 and the direction in which the locking operation portion 35 protrudes from the cover side wall portion 36 is referred to as the protruding direction P, and the width direction of the locked portion 24 and the locking operation portion 35, which is perpendicular to the protruding direction P, is referred to as the width direction W. The direction perpendicular to the protruding direction P and the width direction W coincides with the up-down direction Z in FIG.
[0052] The wire harness WH installed in a vehicle is a bundle of multiple insulated electric wires that electrically connect the electrical devices installed in the vehicle, and depending on the arrangement of the electrical devices, it may be bent multiple times and installed in three dimensions.
[0053] In this embodiment, the wire harness WH is routed with two bent portions. Specifically, the left side XL of the portion of the wire harness WH along the longitudinal direction X is bent toward the front side YF along the lateral direction Y, and the front side YF of the portion of the wire harness WH along the lateral direction Y is bent toward the downward side ZD along the up-down direction Z.
[0054] The protector 10, which regulates and protects the routing path of the wire harness WH thus routed, is formed in a tubular shape bent along the routing path of the wire harness WH, as shown in Fig. 1, and the wire harness WH is inserted inside the protector 10. The wire harness WH inserted into the protector 10 is fixed to the protector 10 by a fixing band (not shown) at a location where the wire harness WH is led out from the protector 10.
[0055] The protector 10 has a shape formed by bending a cylindrical body having a roughly rectangular cross section at two points, and has a protector long portion 11 along the longitudinal direction X, a protector short portion 12 along the lateral direction Y, and a protector upper and lower portion 13 along the vertical direction Z.
[0056] More specifically, the protector 10 is formed in an L-shape in plan view by providing a protector short-side portion 12 that is bent from the left end of the protector long-side portion 11 toward the front side YF. The protector 10 is formed in a horizontal inverted L shape when viewed from the left side XL by providing the protector upper and lower parts 13 so as to bend from the front end of the protector short parts 12 to the downward side ZD. The protector long parts 11, the protector short parts 12, and the protector upper and lower parts 13 are arranged to form a horizontal L shape when viewed from the front side YF.
[0057] The protector longitudinal portion 11 is formed in a cylindrical shape extending along the longitudinal direction X, and is provided at its right end with a band attachment portion 111 for attaching a fixing band (not shown). The protector short portion 12 is formed in a cylindrical shape extending approximately at a right angle from the left end of the protector long portion 11 toward the front side YF, and the internal space of the protector short portion 12 is connected to the internal space of the protector long portion 11.
[0058] At the connecting portion with the protector long portion 11, the outer portion in the bending direction of the protector short portion 12 is formed in an arc shape, and the inner portion in the bending direction is formed in a straight line that extends toward the front side YF as it extends toward the left side XL.
[0059] The protector short-side portion 12 is formed in an L-shape in plan view together with the protector long-side portion 11, and therefore regulates the routing path of the wire harness WH so that the wire harness WH routed inside the protector long-side portion 11 along the longitudinal direction X is bent toward the front side YF. That is, the protector short-side portion 12 regulates the routing path of the wire harness WH so that it follows the transverse direction Y.
[0060] The protector upper / lower part 13 is formed in a cylindrical shape extending from the front end of the protector short part 12 toward the downward side ZD, and the internal space of the protector upper / lower part 13 communicates with the internal space of the protector short part 12. The front side YF of the upper end of the protector upper / lower part 13 is inclined toward the downward side ZD as it approaches the front side YF. A band attachment portion 131 for attaching a fixing band (not shown) is provided at the lower end of the protector upper / lower portion 13. The band attachment portion 131 has substantially the same configuration as the band attachment portion 111.
[0061] The protector upper / lower portion 13, together with the protector short-side portion 12, is formed in a horizontal inverted L shape when viewed from the left side XL, and therefore regulates the routing path of the wire harness WH so that the wire harness WH routed inside the protector short-side portion 12 along the short-side direction Y is bent toward the downward side ZD. That is, the protector upper / lower portion 13 regulates the routing path of the wire harness WH so that it follows the up-down direction Z.
[0062] The protector 10 configured in this manner can route the wire harness WH inside, and can fix the wire harness WH led out from the protector 10 to the band attachment portions 111, 131. This makes it possible to protect the routed wire harness WH while restricting the routing path of the wire harness WH three-dimensionally.
[0063] As shown in FIG. 2, such a protector 10 is composed of a protector main body 20 that surrounds the wire harness WH from three sides and has an opening on one side, and that houses the wire harness WH inside, and a protector cover 30 that covers the opening of the protector main body 20, and is provided with a locking and fixing portion 40 that locks and fixes the protector cover 30 to the protector main body 20 in an assembled state.
[0064] The protector body 20 is formed with a generally concave cross section that extends along the routing path of the wire harness WH. The protector body 20 is integrally formed with a body long portion 21 that corresponds to the protector long portion 11, a body short portion 22 that corresponds to the protector short portion 12, and a body upper / lower portion 23 that corresponds to the protector upper / lower portion 13. The protector body 20 is also provided with a plurality of latched portions 24 for assembling the protector cover 30. The protector body 20 is also provided with mounting and fixing portions (not shown) for fixing to the vehicle.
[0065] As shown in Fig. 3, the main body longitudinal part 21 is formed with a concave cross section that opens to the upper side ZU and extends along the longitudinal direction X (see Fig. 2). As shown in Fig. 3(a), the main body longitudinal part 21 is composed of a plate-shaped longitudinal bottom part 211 having a main surface perpendicular to the up-down direction Z, and plate-shaped main body longitudinal side wall parts 212 that stand upright from both ends of the longitudinal bottom part 211 in the short direction Y toward the upper side ZU.
[0066] The longitudinal bottom portion 211 is formed in the shape of a rectangular plate in plan view, having long sides along the longitudinal direction X and short sides along the lateral direction Y, and the length of the short sides is sufficiently longer than the diameter of the wire harness WH. In addition, near the right end of the longitudinal bottom portion 211, on the front side YF of the central portion in the lateral direction Y, a band insertion hole 213, which is a through-hole having a square shape in plan view, is provided.
[0067] As shown in Figure 3(a), the main body longitudinal side wall portion 212 is composed of a plate-shaped main body longitudinal front side wall 214 erected from the front side YF of the longitudinal bottom portion 211, a plate-shaped main body longitudinal rear side wall 215 erected from the rear side YB and left side XL of the longitudinal bottom portion 211, and a plate-shaped longitudinal band mounting wall 216 erected from the right side XR of the main body longitudinal rear side wall 215.
[0068] 3(a) and 3(b), the main body longitudinal front side wall 214 and the main body longitudinal rear side wall 215 are erected from the longitudinal bottom portion 211 toward the upper side ZU so that their main surfaces face each other, from the left end of the longitudinal bottom portion 211 to the vicinity of the left side XL of the band insertion hole 213. The lengths of the main body longitudinal front side wall 214 and the main body longitudinal rear side wall 215 in the up-down direction Z are sufficiently longer than the diameter of the wire harness WH.
[0069] The longitudinal band mounting wall 216 stands upwardly from a portion corresponding to the band insertion hole 213 on the rear side YB of the longitudinal bottom portion 211 toward the upper side ZU, and is provided so as to be continuous with the main body longitudinal rear side wall 215 along the longitudinal direction X. The length of the longitudinal band mounting wall 216 along the up-down direction Z is shorter than half the length of the main body longitudinal rear side wall 215, and is formed so as to be one step lower on the lower side ZD than the main body longitudinal rear side wall 215.
[0070] A frame-shaped band insertion frame 217 that protrudes toward the back side YB and has insertion holes through which the fixing bands are inserted is provided at the upper end of the longitudinal band mounting wall 216. The band insertion frame 217 has insertion holes that pass through in the up-down direction Z (see FIG. 3(a)). In the main body longitudinal portion 21 configured in this manner, the right side XR of the longitudinal bottom portion 211, the longitudinal band mounting wall 216, and the band insertion frame 217 form a band mounting portion 111.
[0071] The main body short-side portion 22 is provided so as to extend from the left end of the main body long-side portion 21 toward the front side YF, has a concave cross section that opens toward the upper side ZU, and is configured so as to form a horizontal L-shape together with the main body long-side portion 21 in a plan view (see FIG. 2). As shown in FIG. 3(a), the main body short-side portion 22 is configured with a plate-shaped short-side bottom portion 221 having a main surface perpendicular to the up-down direction Z, and a main body short-side side wall portion 222 that stands from the short-side bottom portion 221 toward the upper side ZU.
[0072] In a plan view, the short bottom portion 221 is plate-shaped and extends at a right angle from the left end of the long bottom portion 211 toward the front side YF, and is integrally formed with a trapezoidal bottom portion 223 that extends from the long bottom portion 211 toward the left side XL, and a rectangular bottom portion 224 that extends from the left end of the trapezoidal bottom portion 223 toward the front side YF.
[0073] The trapezoidal bottom 223 is a trapezoidal plate-like shape with a base along the short-side direction Y, with the back side YB formed linearly along the longitudinal direction X and the front side YF formed linearly extending in a diagonal direction toward the front side YF as it approaches the left side XL. That is, the trapezoidal bottom 223 is formed in a plate-like shape that widens from the left end of the long-side bottom 211 toward the front side YF. The diagonally extending portion of the trapezoidal bottom 223 is referred to as a short-side bottom inclined portion 225.
[0074] The rectangular bottom 224 is a rectangular plate extending from the left end of the trapezoidal bottom 223 toward the front side YF, and has short sides along the longitudinal direction X. The length of the rectangular bottom 224 along the longitudinal direction X is approximately the same as the length of the long bottom 211 along the short side direction Y. The rectangular bottom 224 has an end portion on the far side YB and on the left side XL that is chamfered in an arc shape. The arc-shaped portion of the rectangular bottom 224 is referred to as a short bottom arc portion 226.
[0075] The main body short side wall portion 222 is a plate-shaped wall portion whose length and thickness along the vertical direction Z are the same as those of the main body long front side wall 214 and the main body long rear side wall 215, and is formed integrally so as to continue from the main body long side wall portion 212.
[0076] The main body short side wall portion 222 is composed of a main body inner side wall 227 that stands upright from the inner part of the protector short portion 12 in the bending direction relative to the protector long portion 11, and a main body outer side wall 228 that stands upright from the outer part of the bending direction.
[0077] The main body inner side wall 227 is a plate-like member erected from the short bottom inclined portion 225, and is integrally formed so as to extend diagonally from the left end of the main body longitudinal front side wall 214 toward the front side YF as it moves toward the left side XL.
[0078] The outer side wall 228 of the main body is a plate-like member curved in an approximately arc shape that stands upright from the rear end of the trapezoidal bottom 223, the edge of the short bottom arc portion 226, and the left end of the rectangular bottom 224, and extends from the left end of the longitudinal rear wall 215 of the main body on the rear side YB and is integrally formed so as to curve toward the front side YF.
[0079] The main body short-side portion 22 configured in this manner can surround the wire harness WH routed inside from three sides by the short-side bottom portion 221, the main body inner side wall 227, and the main body outer side wall 228. That is, the main body short-side portion 22 is open toward the upper side ZU.
[0080] The upper and lower main body parts 23 are formed to have a concave cross section that opens to the front side YF and is provided so as to extend downward to the downward side ZD from the front end of the main body short arm part 22. In addition, the upper and lower main body parts 23, together with the main body short arm part 22, are configured to form a horizontally inverted L shape when viewed from the left side XL (see FIG. 2).

[0082] The upper and lower bottom portions 231 are formed in the shape of vertically long rectangular plates extending perpendicularly from the front end of the short bottom portion 221 toward the lower side ZD. The length of the short sides of the upper and lower bottom portions 231 in the longitudinal direction X is the same as the length of the rectangular bottom portion 224 in the longitudinal direction X. Further, near the lower end of the upper and lower bottom portions 231, on the right side XR of the center portion in the longitudinal direction X, there is provided a band insertion hole 233 which is a through-hole having a square shape in a side view.
[0083] As shown in Figure 3(b), the upper and lower side wall portions 232 of the main body are composed of a plate-shaped upper and lower left side wall 234 of the main body extending in the vertical direction Z on the left side XL of the upper and lower bottom portion 231, a plate-shaped upper and lower right side wall 235 of the main body extending in the vertical direction Z on the right side XR of the upper and lower bottom portion 231, and a plate-shaped upper and lower band mounting wall 236 extending from the upper and lower left side wall 234 of the main body to the downward side ZD.
[0084] The main body upper and lower left side wall 234 and the main body upper and lower right side wall 235 are rectangular plates in front view extending in the vertical direction Z with their main surfaces facing each other in the longitudinal direction X. The upper side ZU of the main body upper and lower left side wall 234 and the upper and lower right side wall 235 are formed integrally with the front end of the main body short side wall portion 222, and the lower side ZD are formed integrally with both ends in the longitudinal direction X of the upper and lower bottom portion 231. The main body upper and lower left side wall 234 and the main body upper and lower right side wall 235 are provided from the upper end of the main body short side wall portion 222 to the vicinity of the upper side ZU of the band insertion hole 233.
[0085] In addition, at the ends of the front side YF and upper side ZU of the upper and lower left side wall 234 and the upper and lower right side wall 235 of the main body, a side wall inclined portion 237 is formed which inclines toward the lower side ZD as it approaches the front side YF, as shown in Figures 3(b) and 3(c). The lengths of the main body upper and lower left side walls 234 and main body upper and lower right side walls 235 in the short direction Y are substantially the same as the lengths of the main body short side wall portions 222 in the up and down direction Z.
[0086] The upper and lower band mounting walls 236 are arranged to extend from the innermost end of the upper and lower left side walls 234 of the main body to the lower side ZD so as to correspond to the band insertion holes 233 on the lower side ZD of the upper and lower bottom portions 231, and are formed integrally with the lower end of the left side XL of the upper and lower bottom portions 231. In addition, the length of the upper and lower band mounting walls 236 along the short side direction Y is shorter than half the length of the upper and lower left side walls 234 of the main body along the short side direction Y, and is formed one step lower on the rear side YB than the upper and lower left side walls 234 of the main body (see Figure 3(c)).
[0087] A frame-shaped band insertion frame 238 that protrudes to the left side XL and has insertion holes through which the fixing bands are inserted is provided at the front end of the upper and lower band mounting walls 236. The band insertion frame 238 has insertion holes that pass through in the short-side direction Y (see FIG. 3(b)).
[0088] In the upper and lower main body parts 23 configured in this manner, the lower side ZD of the upper and lower bottom parts 231, the upper and lower band mounting walls 236, and the band insertion frame 238 form a band mounting part 131. The main body long side wall portions 212, main body short side wall portions 222, and main body upper and lower side wall portions 232 configured as described above constitute main body side wall portions 25 which are the side walls of the protector main body 20 (see FIG. 2).
[0089] The main body side wall portion 25 is provided with a plurality of engagement portions 24 for assembling and fixing the protector cover 30 to the protector main body 20 . The engaging portion 24, which constitutes the engaging and fixing portion 40 together with the engaging portion 34 of 30 described later, is a roughly frame-shaped body that protrudes outward from the main body side wall portion 25, and is provided in a total of seven locations on the main body long side wall portion 212, the main body short side wall portion 222, and the main body upper and lower side wall portions 232, as shown in Figure 3.
[0090] Specifically, the engaging portion 24 provided on the main body longitudinal side wall portion 212 is provided so as to protrude outward in the short direction Y from near the center in the longitudinal direction X and the center portion in the up-down direction Z of the main body longitudinal front side wall 214 and the main body longitudinal rear side wall 215 (see Figures 3(a) and 3(b)).
[0091] The locked portions 24 provided on the main body short side wall portions 222 are provided on the main body inner side wall 227 and the main body outer side wall 228 . Specifically, the locked portion 24 provided on the main body inner side wall 227 is provided so as to protrude obliquely from the center in the up-down direction Z toward the right side XR and the front side YF.
[0092] The locked portions 24 provided on the main body outer sidewall 228 are disposed in the center of the main body outer sidewall 228 in the up-down direction Z, near the rear side YB of the rectangular bottom portion 224 and the short bottom arc portion 226 on the left side XL. The locked portion 24 on the rear side YB is provided so as to protrude outward from the rear side YB, and the locked portion 24 on the left side XL is provided so as to protrude toward the left side XL. In other words, the locked portions 24 provided on the main body outer sidewall 228 protrude outward from the main body outer sidewall 228.
[0093] The engaging portions 24 provided on the upper and lower side wall portions 232 of the main body are provided on the upper and lower left side wall 234 and the upper and lower right side wall 235 of the main body so as to protrude outward in the longitudinal direction X from a position spaced a predetermined distance above the lower end of the front end on the upper side ZU (see Figures 3(b) and 3(c)).
[0094] The engaging portion 24 arranged in such a position is integrally composed of a frame-shaped engaging frame 241 protruding in the protruding direction P, a flat engaging side flange portion 242 extending in a flange-like shape from the engaging frame 241 in the protruding direction P, and an engaging side connecting portion 243 connecting the engaging frame 241, the engaging side flange portion 242 and the main body side wall portion 25, as shown in Figure 4.
[0095] As shown in Fig. 4(a), the locked frame 241 is formed in a frame shape having through holes along the up-down direction Z, and is spaced a predetermined distance apart along the width direction W, and is integrally configured with a pair of protruding portions 244 that protrude approximately perpendicularly from the main body side wall portion 25, and a protruding connecting portion 245 that connects the tips of the protruding portions 244 along the width direction W. The upper end of the protruding connecting portion 245 on the base end side in the protruding direction P is inclined so as to approach the tip side in the protruding direction P as it approaches the upper end (see Fig. 4(c)).
[0096] The length of the protruding portion 244 in the protruding direction P is shorter than the distance between the pair of protruding portions 244 in the width direction W, and an interlocking hole portion 246, which is a through-hole that penetrates in the up-down direction Z, is formed between the protruding connecting portion 245 and the main body side wall portion 25 in the protruding direction P. The interlocking hole portion 246 is a rectangular through-hole with its long side in the width direction W in a plan view.
[0097] 4(c), the upper ends of the protruding portion 244 and the protruding connecting portion 245 are formed in a plane perpendicular to the vertical direction Z. In other words, the upper end of the locked frame 241 is in a plane perpendicular to the vertical direction Z.
[0098] The engaging side flange portion 242 has a main surface perpendicular to the vertical direction Z and is a rectangular plate in plan view with long sides along the width direction W, and is formed integrally with the engaging frame 241 so as to extend from the engaging frame 241 in the protruding direction P (see Figure 4(a)).
[0099] The locked-side flange portion 242 is formed so that the length in the direction along the protruding direction P, which is the short side, is approximately twice the length of the locked frame 241 in the protruding direction P. Such a plate-shaped locked-side flange portion 242 is provided with a flange through-hole 247 that penetrates in the up-down direction Z at a position a predetermined distance away from the protruding connecting portion 245 on the tip side in the protruding direction P. The flange through-hole 247 is a through-hole that is rectangular in plan view and is provided along the protruding connecting portion 245.
[0100] In addition, on the main surface of the lower side ZD of the retaining side flange portion 242, as shown in Figures 4(b) and 4(c), a retaining side round rib 248, which is a rib with an approximately semicircular cross section that protrudes toward the lower side ZD, is formed along the width direction W at the tip of the protruding direction P.
[0101] The locked-side connecting portion 243 is a rib that connects the lower side ZD of the locked frame 241 and the locked-side flange portion 242 to the main body side wall portion 25, and a pair of them are provided at a predetermined interval along the width direction W (see FIG. 4(b)). The locked-side connecting portion 243 is formed in a right-angled triangular shape when viewed from the width direction W, and is inclined so as to go toward the upper side ZU as it goes toward the tip in the protruding direction P.
[0102] Such a locked-side connecting portion 243 is provided so as to be integrally connected to the lower side ZD of the protruding portion 244, the main surface of the lower side ZD of the locked-side flange portion 242, and the main body side wall portion 25. The interval between the locked-side connecting portions 243 in the width direction W is equal to the interval between the protruding portions 244 in the width direction W. The tips of such a pair of locked-side connecting portions 243 in the protruding direction P are connected by a locked-side rounded rib 248 formed along the width direction W. The locked portion 24 configured in this manner is configured so that the outer periphery of the main surface on the lower side ZD of the locked side flange portion 242 is surrounded by the pair of locked side connecting portions 243 and the locked side round rib 248.
[0103] The protector cover 30 to be assembled to the protector body 20 configured in this manner is configured in the shape of a lid that covers the protector body 20 from the upper side ZU (see FIG. 2). 2, the protector cover 30 is integrally formed of a cover long portion 31 which is a portion corresponding to the protector long portion 11, a cover short portion 32 which is a portion corresponding to the protector short portion 12, and a cover upper / lower portion 33 which is a portion corresponding to the protector upper / lower portion 13. The protector cover 30 also has a locking portion 34 which locks with the locked portion 24 provided on the protector main body 20, and a locking operation portion 35 which protrudes outward from the protector cover 30, provided at a position corresponding to the locked portion 24.
[0104] The cover longitudinal part 31 is formed so as to close the opening on the upper side ZU of the main body longitudinal part 21, and is formed with a concave cross section extending along the longitudinal direction X of the concave cross section opening on the lower side ZD (see FIG. 2). As shown in FIG. 5, the cover longitudinal part 31 is composed of a plate-shaped longitudinal top panel part 311 having a main surface perpendicular to the up-down direction Z, and a pair of cover longitudinal side wall parts 312 erected from both ends of the longitudinal top panel part 311 in the short direction Y toward the lower side ZD. As shown in FIG. 5(a), the top longitudinal panel portion 311 is a rectangular plate-like shape in plan view that is slightly longer than the bottom longitudinal portion 211 in the short direction Y. The top longitudinal panel portion 311 has substantially the same shape as the bottom longitudinal portion 211. As shown in FIG.
[0105] The cover longitudinal side wall portions 312 are a pair of plates spaced a predetermined distance apart in the short direction Y, and the distance along the short direction Y is slightly wider than the distance along the short direction Y between the pair of main body longitudinal side wall portions 212. In addition, the length along the up-down direction Z of the cover longitudinal side wall portions 312 is slightly shorter than the length from the upper end of the main body longitudinal side wall portion 212 to the upper end of the locked portion 24. The cover longitudinal portion 31 configured in this manner can close the opening on the upper side ZU of the main body longitudinal portion 21 from the upper side ZU.
[0106] The cover short-side portion 32 is configured to close the opening on the upper side ZU of the main body short-side portion 22, and is provided so as to extend from the left end of the cover long-side portion 31 to the front side YF, and has a concave cross-section that opens on the lower side ZD (see FIG. 5(a)).

[0130] The upper end of the locking claw portion 342 is disposed at a position spaced apart from the lower end of the cover side wall portion 36 by a distance slightly wider than the length of the locked frame 241 in the vertical direction Z. The upper end of such locking claw portion 342 is formed in a flat shape that is approximately perpendicular to the vertical direction Z.
[0131] As shown in Figure 6, the locking operating portion 35 is composed of a plate-shaped locking side flange portion 351 that protrudes from the lower end of the cover side wall portion 36 in the protruding direction P, and a locking side connecting portion 352 that connects the locking side flange portion 351 and the cover side wall portion 36.
[0132] The locking side flange portion 351 has a main surface perpendicular to the up-down direction Z and is a rectangular plate-like shape in a plan view with long sides along the width direction W, and is formed so as to be wider than the locking portion 34. Specifically, the length of the locking side flange portion 351 along the width direction W is about 1.5 times the length of the locking portion 34 along the width direction W. In addition, the main surface of the lower side ZD of the locking side flange portion 351 is formed flush with the lower end of the cover side wall portion 36. The locking side flange portion 351 is formed so that its length along the width direction W and its length along the protruding direction P are approximately the same as those of the locked portion 24, and the main surface of the lower side ZD is formed so as to face the upper side ZU of the locked portion 24 when the locked portion 24 and the locking portion 34 are locked together.
[0133] As shown in Figure 6(b), on the main surface of the upper side ZU of such a plate-shaped locking side flange portion 351, a locking side round rib 353, which is a rib with an approximately semicircular cross section that protrudes toward the upper side ZU, is formed along the width direction W at the tip in the protruding direction P.
[0134] The locking side connecting portions 352 are ribs that connect the main surface of the lower side ZD of the locking side flange portion 351 to the cover side wall portion 36, and a pair of them are provided at a predetermined interval along the width direction W (see FIG. 6(a)). As shown in FIG. 6(c), the locking side connecting portions 352 are formed in the shape of a right triangle when viewed from the width direction W, sloping toward the lower side ZD as they approach the tip in the protruding direction P. Such locking side connecting portions 352 are provided at intervals substantially the same as the intervals along the width direction W of the locked side connecting portions 243. The ends of the pair of locking-side connecting portions 352 in the protruding direction P are connected by a locking-side rounded rib 353 formed along the width direction W.
[0135] The locking operation portion 35 configured in this manner is formed such that the main surface of the upper side ZU of the locking side flange portion 351 is surrounded at its outer periphery by a pair of locking side connecting portions 352 and locking side round ribs 353.
[0136] 6, the locking operation portion 35 configured in this manner is disposed so as to straddle the center portion of the locking portion 34 in the width direction W. Specifically, the center of the locking portion 34 in the width direction W and the center of the locking operation portion 35 in the width direction W coincide with each other. In this embodiment, the locking operation portion 35 is provided directly above the locking portion 34, and the locking portion 34 and the locking operation portion 35 are close to each other in the up-down direction Z.
[0137] In the protector body 20 and protector cover 30 configured as described above, the engaging portion 24 provided on the protector body 20 and the engaging portion 34 provided on the protector cover 30 form an engaging and fixing portion 40 that engages and fixes the protector body 20 and the protector cover 30.
[0138] The protector 10 can be constructed by assembling and fastening the protector body 20 and the protector cover 30 configured as described above. A method for engaging the locking portion 34 with the locked portion 24 to lock and fix the protector cover 30 to the protector body 20 will be briefly described below with reference to FIGS.
[0139] First, as shown in Fig. 7, a part of the wire harness WH is housed inside the protector main body 20. More specifically, as shown in Fig. 7(a), the wire harness WH routed in the main body long portion 21 is bent toward the front side YF so as to be aligned with the main body short portion 22, so that the wire harness WH is housed along the main body long portion 21 and the main body short portion 22. At this time, the portion of the wire harness WH on the front side YF of the main body short portion 22 is exposed on the front side YF of the protector main body 20, as shown in FIG. 7(b).
[0140] Next, as shown in Figure 8(a), the protector cover 30 is placed on the upper side ZU of the protector main body 20 which houses a portion of the wire harness WH, and a locking operation is performed on the locking operation portion 35 to lock the locked portion 24 and the locking portion 34, thereby locking and fixing the protector main body 20 and the protector cover 30 together.
[0141] Specifically, while aligning the locked portions 24 and the locking portions 34 at their corresponding locations, the protector cover 30 is moved downwardly ZD relative to the protector body 20. At this time, the wire harness WH exposed on the front side YF of the protector body 20 is bent downwardly ZD by the cover upper and lower connecting portions 333, while the protector cover 30 is moved downwardly ZD.
[0142] Then, by performing a locking operation on the locking operation portion 35, as shown in Fig. 8(b), the locked portion 24 and the locking portion 34 can be locked together while the wire harness WH is housed in the protector main body 20. The locking operation for locking the locked portion 24 and the locking portion 34 will be described later.
[0143] Here, by providing the locking operation portion 35, even if the cover upper and lower connecting portion 333 is deformed toward the front side YF due to the repulsive force of the wire harness WH pressed against the lower side ZD, the locked portion 24 and the locking portion 34 can be easily locked by the locking operation.
[0144] In this way, by performing the locking operation on all of the locking operation portions 35 and locking all of the locked portions 24 with the locking portions 34, the protector body 20 and the protector cover 30 can be locked and fixed.
[0145] Next, the locking operation of locking the locked portion 24 and the locking portion 34, which is performed by an operator who assembles, locks, and fixes the protector body 20 and the protector cover 30, will be described with reference to FIG. First, as shown in Figure 9(a), the positions of the engaging portion 24 of the protector main body 20 and the engaging portion 34 of the protector cover 30 are aligned, and the engaging claw portion 342 of the engaging portion 34 is abutted against the protruding connecting portion 245 of the engaging portion 24 from the upper side ZU.
[0146] In this state, the worker pinches the locked-side flange portion 242 and the locking-side flange portion 351 so that they approach each other in the vertical direction Z, in order to apply an external force toward the downward side ZD to the locking-side flange portion 351. Specifically, the worker supports the downward side ZD of the locked-side flange portion 242 with the worker's index finger, and pinches the upper side ZU of the locking-side flange portion 351 with the worker's thumb, pressing it toward the downward side ZD.
[0147] In this way, by applying an external force to the locking side flange portion 351 provided on the cover side wall portion 36, an external force toward the downward side ZD acts on the locking portion 34 provided on the cover side wall portion 36. Here, the locking claw portion 342 of the locking portion 34, on which the external force toward the downward side ZD acts, is inclined so as to approach the locking piece 341 as it approaches the lower end, and therefore an external force toward the tip in the protruding direction P acts on the protruding connecting portion 245 that abuts against the locking claw portion 342. In other words, the locking claw portion 342 toward the downward side ZD deforms the protruding connecting portion 245 toward the locked hole portion 246.
[0148] As a result, by deforming the protruding connecting portion 245 and inserting the locking portion 34 into the locking hole portion 246 provided in the locked portion 24, the locked portion 24 and the locking portion 34 can be locked together as shown in Figure 9(b).
[0149] The protector 10 configured in this manner includes a protector main body 20 having an opening and accommodating a portion of the wire harness WH, a protector cover 30 covering a portion of the opening of the protector main body 20, and a locking and fixing portion 40 that locks and fixes the protector cover 30 in an assembled state to the protector main body 20. The direction in which the protector main body 20 and the protector cover 30 are assembled is defined as the vertical direction Z. The locking and fixing portion 40 includes a locking portion 34 provided on the protector cover 30 and an engaged portion 24 provided on the protector main body 20 and engaged with the locking portion 34. The locking portion 34 protrudes toward the locked portion 24 along the vertical direction Z, and the protector cover 30 is provided with a locking operation portion 35 that protrudes outward in a direction intersecting the vertical direction Z and performs a locking operation to lock the locked portion 24 and the locking portion 34 together.The direction in which the locking operation portion 35 protrudes from the protector cover 30 is perpendicular to the direction P in which the locking operation portion 35 protrudes and the vertical direction Z is the width direction W, and the locking operation portion 35 is arranged in the width direction W so as to straddle the center of the width direction W of the locking portion 34.
[0150] This allows the locking portion 34 and the locked portion 24 to be securely locked together, regardless of the shapes of the protector body 20 and the protector cover 30, thereby locking and fixing the protector body 20 and the protector cover 30 together.
[0151] In detail, the protector main body 20 and the protector cover 30 are brought closer together in the vertical direction Z while aligning the positions of the locking portion 34 and the locked portion 24 provided on the locking fixing portion 40, and by performing a locking operation on the locking operating portion 35, the locking portion 34 and the locked portion 24 are locked together, thereby locking and fixing the protector main body 20 and the protector cover 30 together.
[0152] Specifically, by aligning the positions of the locked portion 24 and the locking portion 34 and performing a locking operation on the locking operation portion 35 provided on the protector cover 30, an external force can be applied to the locking portion 34 provided on the protector cover 30 in a direction along the vertical direction Z toward the protector body 20, i.e., toward the downward side ZD. This allows the locked portion 24 and the locking portion 34 to be deformed and moved to an locking position where the locking portion 34 and the locked portion 24 are locked, and the locking portion 34 and the locked portion 24 can be locked together.
[0153] The locking operation portion 35 is disposed so as to straddle the center of the locking portion 34 in the width direction W. More specifically, since the locking operation portion 35 is disposed so that the center of the locking portion 34 in the width direction W coincides with the center of the locking portion 34 in the width direction W, the external force applied by the locking operation is applied directly and efficiently to the locking portion 34 protruding in the up-down direction Z, and the locking portion 34 and the locked portion 24 can be reliably locked together by the locking operation.
[0154] Therefore, since the protector cover 30 is provided with a locking operation portion 35, regardless of the shapes of the protector main body 20 and the protector cover 30, the locking portion 34 and the locked portion 24 can be securely locked together by performing a locking operation on the locking operation portion 35, and the protector main body 20 and the protector cover 30 can be assembled and locked and fixed.
[0155] In addition, the locking operation portion 35 is formed in a plate shape having a predetermined length in the width direction W, and the protector cover 30 has a cover side wall portion 36 extending in the vertical direction Z, and the cover side wall portion 36 is provided with the locking operation portion 35 and a locking portion 34, and a locking side connecting portion 352 is provided to connect the main surface of the plate-shaped locking operation portion 35 to the cover side wall portion 36.
[0156] This allows the locking operation to be performed on the main surface of the locking operation portion 35 that intersects with the up-down direction Z, making the locking operation easy. Furthermore, the locking side connecting portion 352 that connects the protruding locking operation portion 35 and the cover side wall portion 36 can improve the rigidity of the locking operation portion 35. This allows the external force applied to the locking operation portion 35 to be used efficiently as an external force that locks the locking portion 34 and the locked portion 24. In other words, the locking operation can more reliably lock the locking portion 34 and the locked portion 24 together.
[0157] Furthermore, since the locking side connecting portions 352 are arranged at both ends of the locking operation portion 35 in the width direction W, the locking side connecting portions 352 arranged at both ends of the width direction W improve the rigidity of the locking operation portion 35, while allowing the locking operation to be performed using the central portion of the locking operation portion 35 in the width direction W, thereby improving the locking operability.
[0158] In addition, a locking side round rib 353 is provided on the main surface of the upper side ZU of the locking operation part 35 to prevent slipping during the locking operation, so that the fingers or jig of the worker performing the locking operation can be prevented from slipping off the locking operation part 35, and the locking operation can be performed reliably.
[0159] The protector body 20 is also provided with a locked flange portion 242 that assists the locking operation, and the locked flange portion 242 is disposed at a position corresponding to the locking operation portion 35 in the width direction W.
[0160] This makes it possible to assist the locking operation by the locked-side flange portion 242 provided at a position corresponding to the locking operation portion 35. In other words, the locking operation can be performed by sandwiching the locking operation portion 35 provided on the protector cover 30 and the locked-side flange portion 242 provided on the protector body 20 in the vertical direction Z, thereby improving the workability of the locking operation. Alternatively, a locking operation can be performed on the locking operation portion 35 using the locked side flange portion 242 as a fulcrum, and an external force can be easily applied to the locking operation portion 35 toward the downward side ZD.
[0161] The locking flange portion 351 and the locked flange portion 242 that constitute the locking operation portion 35 are formed in the shape of plates having a predetermined length in the width direction W, and are opposed to each other in the up-down direction Z. This allows the locking operation to be performed by utilizing the main surfaces of both the locking side flange portion 351 and the locked side flange portion 242 that intersect with the vertical direction Z, thereby clamping the locking side flange portion 351 and the locked side flange portion 242, further improving the workability of the locking operation.
[0162] In addition, the locking portion 34 is provided on the protector cover 30, and the locked portion 24 is provided on the protector main body 20, and the locked portion 24 protrudes in the protruding direction P of the locking operating portion 35 and is formed in a frame shape into which the locking portion 34 can be inserted, and the locked portion 24 and the locked side flange portion 242 are integrally configured.
[0163] This improves the rigidity of the locked flange 242, which is formed integrally with the locked portion 24, and prevents the locked flange 242 from deforming when performing a locking operation in which the locking operation portion 35 and the locked flange 242 are sandwiched between them. Therefore, the external force applied by the locking operation can be reliably applied as an external force that inserts the locking portion 34 into the locked portion 24 while deforming the locked portion 24, and the locking portion 35 and the locked portion 24 can be reliably locked together. Furthermore, by forming the locked portion 24 and the locked flange 242 integrally, it is possible to save space in the protector 10 and simplify its structure.
[0164] Furthermore, a flange through-hole 247 penetrating in the vertical direction Z is formed in the locked-side flange portion 242, and the flange through-hole 247 is provided in the vicinity of the location where the locking portion 34 locks with the locked portion 24. In other words, the locked-side flange portion 242 is provided with the flange through-hole 247 penetrating in the vertical direction Z at a position spaced a predetermined distance from the protruding connecting portion 245 toward the tip end in the protruding direction P.
[0165] As a result, when engaging the engaging portion 34 with the engaged portion 24, by deforming the protruding connecting portion 245 located near the flange through hole 247 in the engaged portion 24, the engaging portion 34 can be easily inserted into the engaged portion 24, and the engaging portion 34 and the engaged portion 24 can be easily engaged with each other.
[0166] In addition, the protector main body 20 has a main body side wall portion 25 extending in the vertical direction Z, and is provided with an engaging portion 24 and an engaging side flange portion 242 on the main body side wall portion 25, and is provided with an engaging side connecting portion 243 that connects the main surface of the lower side ZD of the engaging side flange portion 242 to the main body side wall portion 25 and the engaging portion 24, and the protector cover 30 has a cover side wall portion 36 extending in the vertical direction Z, and is provided with an engaging portion 34 and an engaging operating portion 35 on the cover side wall portion 36, and is provided with an engaging side connecting portion 352 that connects the main surface of the upper side ZU of the engaging operating portion 35 to the cover side wall portion 36.
[0167] As a result, the rigidity of the locked-side flange 242 can be improved by the locked-side connecting portion 243 that connects the main body side wall 25 and the locked portion 24 to the locked-side flange 242, and the rigidity of the locking operation portion 35 can be improved by the locking-side connecting portion 352 that connects the cover side wall 36 to the locking operation portion 35. This allows the external force applied to the locking operation portion 35 and the locked-side flange 242 to be used efficiently as an external force that locks the locking portion 34 to the locked portion 24. In other words, the locking operation can reliably lock the locking portion 34 to the locked portion 24.
[0168] In addition, because the locked-side connecting portion 243 is provided on the main surface of the lower side ZD of the locked-side flange portion 242 and the locking-side connecting portion 352 is provided on the main surface of the upper side ZU of the locking operation portion 35, the locking operation portion 35 and the locked-side flange portion 242 can be provided close to each other in the up-down direction Z, improving the operability of the locking operation. Furthermore, when the locked portion 24 and the locking portion 34 are locked together, unintentional interference between the locked-side connecting portion 243 and the locking-side connecting portion 352 can be prevented.
[0169] Furthermore, since the locking side connecting portions 352 are arranged at both ends of the locking operation portion 35 in the width direction W, the locking side connecting portions 352 arranged at both ends of the width direction W improve the rigidity of the locking operation portion 35, and the locking operation can be performed using the central portion of the locking operation portion 35 in the width direction W, making it easy to perform the locking operation.
[0170] In addition, the locking side connecting portion 352 is arranged at both ends of the locking operating portion 35 in the width direction W, and the locked side connecting portion 243 is arranged at both ends of the locked side flange portion 242 in the width direction W. As a result, the locking side connecting portion 352 and the locked side connecting portion 243, which are arranged at both ends in the width direction W, improve the rigidity of the locking operation portion 35 and the locked side flange portion 242, while allowing the locking operation to be performed using the central portion in the width direction W between the locking operation portion 35 and the locked side flange portion 242, making the locking operation easy to perform.
[0171] Furthermore, a locking side round rib 353 is provided on the main surface of the upper side ZU of the locking operation portion 35 to prevent slippage during the locking operation, and a locking side round rib 248 is provided on the main surface of the lower side ZD of the locked side flange portion 242 to prevent slippage during the locking operation, so that the fingers or jig of the worker performing the locking operation can be prevented from slipping off from the locking operation portion 35 and the locked side flange portion 242, and the locking operation can be performed reliably.

[0173] For example, in the present embodiment, the wiring path of the wire harness WH is set as a three-dimensional path bent at two points, but the wiring path of the wire harness WH may be a linear path, a planar path bent at one point, or a path bent at three or more points.
[0174] In addition, in the present embodiment, a wire harness WH formed by bundling insulated electric wires is inserted into the protector 10, but a single insulated electric wire, a communication cable such as an optical fiber cable for transmitting information, or a bundle of communication cables may be inserted into the protector 10. In addition, a hose through which a fluid such as washer fluid or coolant flows, a corrugated tube containing the wire harness WH inside, or a single corrugated tube may be inserted into the protector 10.
[0175] In addition, in this embodiment, the protector body 20 and the protector cover 30 are configured as separate bodies, but the protector body 20 and the protector cover 30 may be partially connected to each other so that they can be opened and closed. Specifically, the protector body 20 and the protector cover 30 may be connected by a hinge.
[0176] Furthermore, in this embodiment, the locking portion 24 is provided on the protector body 20, and the locking portion 34 and the locking operation portion 35 are provided on the protector cover 30, but the locking portion 34 and the locking operation portion 35 may be provided on the protector body 20, and the locking portion 24 may be provided on the protector cover 30.

In addition, in this embodiment, the locked portion 24 and the locking portion 34 protrude in a direction perpendicular to the vertical direction Z, but may also be inclined in the vertical direction Z.
[0178] In this embodiment, the locking operation is performed by the fingers of the worker performing the assembly work, but it may also be performed by a jig of an assembly device.
