Description

[Technical field]

[0001] The present invention relates to, for example, a harness routing structure in which an exterior material that exteriorly covers a wire harness extending from a connection target member is connected to the connection target member, and a connecting member that protects the wire harness. [Background technology]

[0002] Wire harnesses that transmit power and control signals to electrical components mounted in automobiles are routed in a two-dimensional or three-dimensional curve along a desired routing path. Such wire harnesses are sometimes protected by a flexible exterior material.

[0003] For example, a harness wiring structure in which a wire harness led out from a connector is inserted into a corrugated tube connected to the connector is disclosed in Patent Document 1. In the harness wiring structure disclosed in Patent Document 1, since the wire harness is inserted into a flexible corrugated tube, it is said that the wire harness led out from the connector can be wired along a desired wiring path and protected.

[0004] In recent years, the number of electrical equipment installed in automobiles has been increasing in order to improve safety and comfort. However, as living space tends to expand, there is a demand for installing electrical equipment in a space-saving manner. However, in the harness routing structure disclosed in Patent Document 1, the corrugated tube, which is the exterior material that protects the wire harness, is flexible, and therefore there was a risk that it would unintentionally interfere with other components, such as peripheral devices, placed nearby due to vibration or the like. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2020-202073 A Summary of the Invention [Problem to be solved by the invention]

[0006] The present invention aims to provide a harness routing structure and connecting member that can prevent interference between an outer casing through which a wire harness passes and other components, such as peripheral devices, that are arranged around the routing path of the wire harness, even when an unintended external force is applied. [Means for solving the problem]

[0007] The present invention is characterized in that it is a harness arrangement structure comprising a wire harness, an exterior material that is flexible and exteriors the wire harness, a connection target member having a derivation portion from which the wire harness is derived, and a connecting member through which the wire harness derived from the derivation portion is inserted and which connects the exterior material and the derivation portion, wherein the connecting member is hard and a regulating portion is provided at a joint portion joining the connecting member and the derivation portion, the regulating portion regulating the connection direction of the exterior material to the derivation portion.

[0008] The present invention is also characterized in that the connecting member includes a connection target member having a derivation portion from which a wire harness is derived, a first joint portion that joins the derivation portion, a second joint portion that is flexible and joins an exterior material that sheathes the wire harness derived from the derivation portion, and a hard insertion portion that is arranged between the first joint portion and the second joint portion and through which the wire harness derived from the derivation portion is inserted, and the first joint portion is provided with a joint side regulating portion that regulates the connection direction of the exterior material to the connection target member.

[0009] The exterior material is a flexible member capable of protecting the wire harness, and includes, for example, harness protection tubes such as corrugated tubes and shrinkable tubes, or insulating tapes wound around the wire harness to protect it.

[0010] The connection target member is a member that houses a part of the wire harness and has an outlet port for leading out the wire harness, and includes a connector, an electric connection box, a fuse box, or the like. The restricting portion restricts the rotation of the exterior material relative to the connection target member and the movement of the exterior material along the leading-out direction of the wire harness led out from the lead-out port.

[0011] According to the present invention, even if an unintended external force is applied, interference between the exterior material that exteriors the wire harness and other members such as peripheral devices arranged around the routing path of the wire harness can be prevented. In more detail, a restricting portion is provided at the joint between the lead-out portion and the exterior material and a hard connecting member that connects the lead-out portion and the exterior material, so that the connecting direction of the exterior material to the lead-out portion can be restricted with the end of the exterior material on the lead-out portion side (hereinafter referred to as the end of the exterior material) being positioned at a desired location. This allows the connection target member and the exterior material to be connected with the exterior material facing in a desired direction with respect to the lead-out portion, so that even if an unintended external force such as vibration acts, interference between the exterior material and other members such as peripheral devices can be suppressed.

[0012] In one aspect of the present invention, the direction in which the wire harness is led out from the lead-out portion is defined as the lead-out direction, the connecting member is provided with a bending portion that bends in a direction intersecting the lead-out direction, and the regulating portion may be a rotation regulating portion that regulates rotation of the connecting member relative to the connection target member around an axis along the lead-out direction as a rotation center. The rotation restricting portion includes a portion that restricts rotation by engaging the connecting member with the lead-out portion, and a portion that restricts rotation via a contact surface at the joint between the connecting member and the lead-out portion.

[0013] According to this invention, by having the bent portion, the end portion of the exterior material can be arranged in a direction away from the other member. Also, since the connecting member having the bent portion and the lead-out portion are joined via the rotation restricting portion, the rotation of the connecting member relative to the lead-out portion can be restricted. In other words, the exterior material can be more effectively prevented from interfering with the other member.

[0014] In another aspect of the present invention, a rectangular tubular portion configured in a rectangular shape when viewed from the lead-out direction is provided on one of the joint portions of the connecting member and the lead-out portion, and an outer fitting portion that fits around the rectangular tubular portion is provided on the other of the joint portions of the connecting member and the lead-out portion, and the rectangular tubular portion and the outer fitting portion abut circumferentially, thereby functioning as the rotation regulating portion.

[0015] According to this invention, the rectangular tubular portion of one of the connecting member and the lead-out portion is externally fitted with the external fitting portion of the other of the connecting member and the lead-out portion, thereby restricting rotation at the joint between the connecting member and the lead-out portion. In detail, the external fitting portion of the other of the connecting member and the lead-out portion is fitted onto the rectangular tubular portion of one of the connecting member and the lead-out portion, so that the rectangular tubular portion and the external fitting portion abut in the circumferential direction. Therefore, the other of the connecting member and the lead-out portion resists the rotation of one of the connecting member and the lead-out portion. Therefore, even if the connecting member and the lead-out portion attempt to rotate relative to the lead-out direction, the relative rotation of the external fitting portion with respect to the rectangular tubular portion can be restricted.

[0016] In another aspect of the invention, the rectangular tubular portion may have a rib that protrudes rectangularly when viewed from the lead-out direction, the inner surface of the external fitting portion may be configured rectangularly when viewed from the lead-out direction, and the outer surface of the rib and the inner surface of the external fitting portion may abut circumferentially, thereby functioning as the rotation regulating portion.

[0017] According to this invention, the outer surface of the rib provided on the rectangular tubular portion abuts against the inner surface of the outer fitting portion in the circumferential direction, so that the outer fitting portion can be restricted from rotating relative to the rectangular tubular portion. Therefore, rotation can be restricted reliably with a simple structure.

[0018] As a further aspect of the present invention, the rectangular tube portion may have a shape in which corners are chamfered when viewed from the lead-out direction. According to this invention, the corners of the rectangular tubular portion are chamfered, so that the insertion of the rectangular tubular portion into the outer fitting portion can be improved while rotation of the connecting member can be reliably restricted.

[0019] In another aspect of the invention, the rib includes a first rib and a second rib arranged at a predetermined distance from the first rib along the lead-out direction, at least two engagement recesses capable of engaging with the first rib are arranged side by side along the lead-out direction on the inner surface side of the external fitting portion, and an accommodating portion capable of accommodating the second rib is provided on the side of the engagement recess opposite the lead-out portion, and the distance between adjacent engagement recesses may be different from the distance between the first rib and the second rib.

[0020] According to this invention, since the distance between the at least two fitting recesses is different from the distance between the first rib and the second rib, when the second rib is inserted into the fitting recess, the first rib does not enter the fitting recess and interferes with the inner surface of the lead-out portion, thereby preventing incorrect assembly when assembling the connecting member and the lead-out portion by fitting them together.

[0021] In another aspect of the invention, the rib may include a first rib and a second rib arranged at a predetermined distance from the first rib along the lead-out direction, at least one engagement recess capable of engaging with the first rib may be arranged side by side along the lead-out direction on the inner surface side of the external fitting portion, and an accommodating portion capable of accommodating the second rib may be provided on the side of the engagement recess opposite the lead-out portion, and the second rib may have a thickness greater than the width of the engagement recess.

[0022] It is sufficient that at least a portion of the second rib has a thickness greater than the width of the mating recess, and this includes, for example, a case in which the entire thickness of the second rib is large, or a case in which a protrusion along the lead-out direction is provided on a portion of the second rib. According to this invention, it is possible to prevent the second rib from fitting into the fitting recess, thereby preventing an incorrect assembly when assembling the connecting member and the lead-out portion by fitting them together.

[0023] As another aspect of the present invention, the exterior material may be formed of a corrugated tube in which small diameter portions and large diameter portions are alternately formed at a predetermined interval along the longitudinal direction, and the fitting recess may be provided in the lead-out portion and configured to be able to fit the large diameter portion.

[0024] According to this invention, the fitting recess provided in the lead-out portion is formed so that the large diameter portion of the corrugated tube can be fitted therein, so that the connecting member can be connected to a connection target member configured to be able to connect to the corrugated tube, thereby making it possible to configure a highly versatile harness routing structure.

[0025] As a further aspect of the present invention, the joint portion may be provided with an assembly restriction portion that restricts an assembly direction of the rectangular tube portion and the outer fitting portion. The assembly restricting portion includes a structure that restricts assembly by interfering with at least one of the rectangular tube portion and the outer fitting portion when the assembly is performed in an incorrect assembly direction.

[0026] According to this invention, by providing an assembly control portion at the joint portion, incorrect assembly is prevented when assembling the rectangular tube portion and the outer fitting portion, and the connection target member and the outer casing material can be connected with the outer casing material facing in the desired direction relative to the lead-out portion. Effect of the Invention

[0027] The present invention makes it possible to provide a harness routing structure and connecting member that can prevent interference between the outer casing through which the wire harness passes and other components, such as peripheral devices, that are arranged around the routing path of the wire harness, even when an unintended external force is applied.

In addition, in FIG. 8(b), the harness 10 and the exterior material 20 are omitted.

[0031] Here, in FIG. 1, the up-down direction in the figure is the insertion direction L, and the direction perpendicular to the insertion direction L and along the left-right direction in the figure is the width direction W. The direction perpendicular to the insertion direction L and the width direction W is the height direction H. In FIG. 1, the upper side along the insertion direction L is the connection side La, and the lower side is the lead-out side Lb. Similarly, the left side along the width W is the left side Wl, the right side along the width W is the right side Wr, the back side of the paper is the lower side Hd, and the front side of the paper is the upper side Hu along the height direction H. The directions defined in FIG. 1 are the same in FIG. 2 to FIG. 9.

[0032] As shown in Figures 1 to 3, the harness routing structure 1 is composed of a harness 10 to be routed in a vehicle, a long exterior material 20 that exteriorizes a portion of the harness 10, a connecting connector 30 connected to the end of the harness 10 opposite the exterior material 20, and a connecting member 40 through which the harness 10 is inserted and which connects the exterior material 20 and the connecting connector 30.

[0033] The harness routing structure 1 configured in this manner connects the linking connector 30 connected to the harness 10 to the electrical component Z, and also connects a connector (not shown) provided at the other end of the harness 10 to another electrical component, thereby electrically connecting the electrical component Z to the electrical component. Note that around the connecting member 40 connected to the linking connector 30, more specifically on the left side Wl and outlet side Lb of the connecting member 40, a bracket B and an armor pipe G held by the bracket B are disposed (see Figs. 1 and 2).

[0034] The harness 10 is a wire harness in which a plurality of insulated electric wires, each having a conductor surrounded by an insulating coating, are bundled together, and is routed along a predetermined routing path. In this embodiment, the harness 10 is a bundle of a plurality of insulated electric wires, but it may be a bundle of insulated electric wires and communication cables, or may be a bundle of only a plurality of communication cables.

[0035] The exterior material 20 is a cylindrical corrugated tube made of resin, into which the harness 10 is inserted. More specifically, as shown in Fig. 4(a) and Fig. 4(b), the exterior material 20 has a flexible bellows structure in which large diameter portions 21 whose outer circumferential surface protrudes radially outward over the entire circumference and small diameter portions 22 whose outer circumferential surface is recessed radially inward over the entire circumference are alternately and continuously arranged along the longitudinal direction.

[0036] The exterior material 20 having such a bellows structure has a slit 23 formed by cutting one location on the outer peripheral surface in a straight line along the longitudinal direction from one end to the other end (see FIG. 4(a)).

[0037] The linking connector 30 is a connector that can be connected to a connector connection portion Z1 provided on the electrical component Z. More specifically, the linking connector 30 is composed of a connector main body 31 configured to be able to fit into the connector connection portion Z1, and a lead-out portion 32 provided on the lead-out side Lb of the connector main body 31. The connector main body 31 and the lead-out portion 32 are in communication with each other so that the harness 10 can be inserted therethrough.

[0038] 5(a), the connector body 31 is a hollow housing configured to be able to fit into the connector connection part Z1, and accommodates terminals (not shown) connected to ends of conductors that constitute the harness 10. The connector body 31 configured in this manner can electrically connect the terminals held therein and the terminals accommodated in the connector connection part Z1 by fitting the end of the coupling side La into the connector connection part Z1.

[0039] The lead-out portion 32 is a hollow tubular body protruding from the end of the lead-out side Lb of the connector body 31, and has a substantially rectangular cross-sectional shape perpendicular to the insertion direction L. The lead-out portion 32 has, at the end of the lead-out side Lb, a lead-out opening 321 for leading out the harness 10 connected to the terminal held in the connector body 31 toward the lead-out side Lb.

[0040] The lead-out portion 32 will be described in detail. As shown in Fig. 5(b) and Fig. 6(a), the lead-out portion 32 is composed of a concave upper lead-out portion 33 that opens on the lower side Hd, and a concave lower lead-out portion 34 that is integral with the connector body 31 and opens on the upper side Hu. The lead-out portion 32 also has a locking portion 35 that locks and fixes the upper lead-out portion 33 and the lower lead-out portion 34 together.

[0041] As shown in Figures 5(b), 6(a) and 6(b), three annular ribs 36 are provided at a predetermined interval on the inside of the lead-out portion 32 configured as described above, extending from the end of the lead-out side Lb toward the connecting side La. A partition wall 37 is provided at the end of the connecting side La of the lead-out portion 32 to separate the boundary between the connector body 31 and the lead-out portion 32. A first fitting groove 38 is formed between adjacent annular ribs 36, and a second fitting groove 39 is formed between the annular rib 36 provided on the connecting side La and the partition wall 37.

[0042] The upper lead-out portion 33 has a gate-shaped shape in a front view with the corners of the outer edge and the inner edge being chamfered when viewed from the lead-out side Lb. In detail, as shown in Fig. 6(a), the upper lead-out portion 33 is integrally formed with an upper surface portion 331 forming the upper surface of the lead-out portion 32, an upper inclined wall portion 332 extending from both ends of the upper surface portion 331 while inclining, and a pair of upper side wall portions 333 erected from the ends of the upper inclined wall portion 332 toward the lower side Hd.

[0043] The upper surface portion 331 is a rectangular flat plate having long sides aligned along the insertion direction L in a plan view. The upwardly inclined wall portion 332 is a flat plate that protrudes outward from the outer end of the upper surface portion 331, and is inclined outward as it approaches the lower side Hd. The upwardly inclined wall portion 332 has a long side with a length equal to the length of the upper surface portion 331 in the insertion direction L.

[0044] The upper side wall portion 333 has approximately the same thickness as the top surface portion 331 and the upper inclined wall portion 332, and is a flat plate having a long side equal to the length of the top surface portion 331 in the insertion direction L. 6(b), a pair of extension walls 334 are provided in the insertion direction L at both ends of the flat upper side wall 333 in the insertion direction L. The extension walls 334 protrude outward from the outer surface of the upper side wall 333 by a predetermined length. The extension walls 334 are provided from one end to the other end of the upper side wall 333 in the height direction H. That is, the upper side wall 333 is formed in a substantially concave shape when viewed from the upper side Hu.

[0045] The upper side wall portion 333 thus formed in a generally concave shape in plan view is provided at a central portion in the insertion direction L and height direction H with a locking protrusion 351 protruding outward (see FIG. 3). The locking protrusion 351 is a protruding piece having a predetermined width and formed in a substantially rectangular shape when viewed from the outside in the width direction W, and has a bottom surface that is inclined to the upper side Hu as it extends outward from the main surface of the upper side wall portion 333. The amount of protrusion of the locking protrusion 351 is substantially equal to the amount of protrusion of the extension wall portion 334.

[0046] In addition, on the lower side Hd surface of the gate-shaped upper lead-out portion 33 configured in this manner, three lower chord ribs 361 are provided at a predetermined interval in order from the lead-out side Lb, as shown in Figure 5 (b), and an upper partition portion 371 is provided at the end of the connecting side La of the upper lead-out portion 33.

[0047] The lower chord rib 361 is a rib that protrudes from the concave surface of the upper lead-out portion 33 so as to form a semicircular shape having an opening on the lower side in a front view seen from the lead-out side Lb. The inner diameter of the lower chord rib 361 is approximately equal to the outer diameter of the small diameter portion 22.

[0048] The lower chord ribs 361 thus configured are arranged in three rows from the end of the lead-out side Lb toward the connecting side La at intervals approximately equal to the intervals between the large diameter portions 21. In addition, the lower chord rib 361 provided on the lead-out side Lb is arranged so as to be flush with the upper lead-out portion 33 at the end of the lead-out side Lb. Here, the space between the lower chord ribs 361 spaced at a distance substantially equal to the distance between the large diameter portions 21 is defined as an upper fitting recess 381.

[0049] The upper partition 371 is a rib that protrudes from the concave surface of the upper lead-out portion 33 to form a semicircular shape with an opening on the lower side, similar to the lower chord rib 361, in a front view seen from the lead-out side Lb.

[0050] Here, the space between the lower chord rib 361 and the upper partition portion 371 is defined as an upper accommodating portion 391. The length of the upper accommodating portion 391 in the insertion direction L is twice the length of the upper fitting recess 381 in the insertion direction L.

[0051] On the other hand, the downward lead-out portion 34 has a gate-shaped shape in a front view that is substantially plane-symmetrical with the upward lead-out portion 33, with a plane perpendicular to the height direction H as a symmetry plane. In more detail, the downward lead-out portion 34 has a gate-shaped shape in a front view with an opening on the upper side Hu and with chamfered corners on the outer and inner edges, and is composed of a bottom surface portion 341 that forms the bottom surface of the lead-out portion 32, downward inclined wall portions 342 that extend from both ends of the bottom surface portion 341 while being inclined, and a pair of lower side wall portions 343 that stand from the ends of the upper inclined wall portion 332 toward the upper side Hu.

[0052] The bottom surface portion 341 has substantially the same shape as the top surface portion 331 in a plan view, and is a rectangular flat plate having long sides along the insertion direction L. The downward inclined wall portion 342 is a flat plate that protrudes outward from the outer edge of the upper surface portion 331 and is inclined outward as it approaches the upper side Hu. The upward inclined wall portion 332 has a long side with a length substantially equal to the length of the upper surface portion 331 in the insertion direction L.

[0053] The lower side wall portion 343 is a flat plate having approximately the same thickness as the bottom surface portion 341 and the downward inclined wall portion 342, and having a long side approximately equal to the length of the bottom surface portion 341 in the insertion direction L, and a pair of locking frames 352 extending upward Hu are provided in the center of the outer surface in the insertion direction L (see Figure 3). The locking frame 352 is a gate-shaped frame body that is open on the lower side Hd when viewed from the right side Wr. More specifically, the locking frame 352 is a frame body that is configured with a pair of standing pieces that stand in the height direction H at a distance equal to the width length (length in the insertion direction L) of the locking protrusion 351, and a connecting piece that connects the ends of the upper sides Hu of the standing pieces. The length of the connecting piece in the insertion direction L is approximately equal to the distance between the extension wall portions 334.

[0054] The concave surface of the downward lead-out portion 34 configured in this manner is provided with three upper chord ribs 362 and a lower partition portion 372 that separates the boundary with the connector main body 31 at the end of the connection side La of the downward lead-out portion 34, similar to the upper lead-out portion 33. In addition, a lower fitting recess 382 is defined between the upper chord ribs 362, and a lower accommodation portion 392 is defined between the upper chord ribs 362 and the lower partition portion 372.

[0055] Details of the upper chord rib 362 and the lower partition portion 372 are similar to the lower chord rib 361 and the upper partition portion 371, respectively, except that their shapes are upside down, so a detailed explanation will be omitted. Similarly, details of the lower fitting recess 382 and the lower accommodating portion 392 are similar to the upper fitting recess 381 and the lower accommodating portion 392, respectively, so a detailed explanation will be omitted.

[0056] The upper lead-out portion 33 and the lower lead-out portion 34 thus configured can be assembled from the height direction H such that the locking frame 352 is inserted between the pair of extension walls 334. By locking the locking protrusions 351 and the locking frame 352 in this manner, the upper lead-out portion 33 and the lower lead-out portion 34 form the lead-out portion 32, which is a hollow cylindrical body (see FIG. 3). The locking protrusion 351 provided on the upper lead-out portion 33 and the locking frame 352 provided on the lower lead-out portion 34 constitute a locking portion 35 .

[0057] In addition, on the inside of the lead-out section 32, which is formed by assembling the upper lead-out section 33 and the lower lead-out section 34 as described above, three annular ribs 36 consisting of a lower chord rib 361 and an upper chord rib 362, and a partition wall 37 consisting of an upper partition section 371 and a lower partition section 372 are provided.

[0058] 6(a) and 6(b), the annular rib 36 composed of the lower chord rib 361 and the upper chord rib 362 forms an insertion hole that is approximately circular in front view and has an inner diameter equal to the outer diameter of the small diameter portion 22. The partition wall 37 communicates with the connector main body 31 and forms an insertion hole that is approximately circular in front view and has an inner diameter smaller than the outer diameter of the small diameter portion 22.

[0059] Furthermore, the pair of upper fitting recess 381 and lower fitting recess 382 facing each other in the height direction H constitutes a first fitting groove 38. Similarly, the upper accommodating portion 391 and the lower accommodating portion 392 constitute a second fitting groove 39. Note that the inner circumferential surfaces of the first fitting groove 38 and the second fitting groove 39 are formed in a substantially rectangular shape having chamfered corners when viewed from the front from the outlet side Lb.

[0060] As described above, the extension wall portion 334 protrudes from the upper side wall portion 333. Therefore, in the lead-out portion 32 in which the upper lead-out portion 33 and the lower lead-out portion 34 are assembled, as shown in Fig. 6(b) , a step portion 322 having a dimensional difference in the width direction W corresponding to the protruding length of the extension wall portion 334 is formed between the upper lead-out portion 33 and the lower lead-out portion 34 at both ends of the lower side wall portion 343 in the insertion direction L.

[0061] The connecting member 40 is a hard cylindrical body curved in a plan view, and has a degree of rigidity that does not easily deform even when an external force is applied. In detail, as shown in Fig. 7(a), the connecting member 40 is integrally composed of a rectangular tube portion 50 having one end (the end of the connecting side La) connected to the lead-out portion 32, an intermediate curved portion 60 connected to the other end (the end of the lead-out side Lb) of the rectangular tube portion 50, and a tube portion 70 connected to the other end (the end of the lead-out side Lb) of the intermediate curved portion 60.

[0062] The rectangular tube portion 50 is a linear tube extending along the insertion direction L, and as shown in FIG. 7(a), is composed of a first tube portion 51 having a cylindrical shape, two engaging ribs 52 arranged in order from the intermediate curved portion 60 side, and a positioning rib 53 spaced a predetermined distance from the engaging rib 52.

[0063] The first tubular portion 51 is a cylinder having an outer diameter approximately equal to the inner diameter of the insertion hole formed by the annular rib 36 and an inner diameter approximately equal to the inner diameter of the insertion hole formed by the partition wall 37, and extends along the insertion direction L a length approximately equal to the length of the insertion direction L in the lead-out portion 32.

[0064] The fitting rib 52 is a rib that is rectangular in front view and protrudes outward from the outer circumferential surface of the first tubular portion 51. More specifically, the fitting rib 52 is a substantially rectangular rib with chamfered corners when viewed from the connecting side La so that the fitting rib 52 has an outer edge that is substantially the same shape as the inner circumferential surface of the first fitting groove 38. The plate thickness of the fitting rib 52 is substantially equal to the width of the first fitting groove 38. The fitting ribs 52 thus configured are provided side by side in the insertion direction L at a distance equal to the distance between the annular ribs 36 .

[0065] The positioning rib 53 is a rib that is rectangular in front view and configured to have the same shape as the fitting rib 52 when viewed from the connecting side La, and is provided so as to be flush with the end face of the connecting side La of the first tubular portion 51. Furthermore, the positioning rib 53 is provided at the center of each of the upper side Hu and lower side Hd with two protrusions 54 that protrude from the main surface toward the fitting rib 52 and are spaced a predetermined distance apart in the width direction W.

[0066] The protrusion 54 is a protruding piece that protrudes toward the outlet side Lb by a length equal to the plate thickness of the positioning rib 53, and is provided along the height direction H from the outer circumferential surface of the first cylindrical portion 51 to the outer edge of the positioning rib 53. Note that a gap equal to the length in the insertion direction L of the annular rib 36 is provided between the tip of the protrusion 54 and the fitting rib 52 arranged on the connection side La.

[0067] The rectangular cylinder portion 50 thus configured is divided into two in the height direction H. In the assembled state, the upper side Hu is the upper rectangular cylinder portion 50a, and the lower side Hd is the lower rectangular cylinder portion 50b (see FIG. 7(b)). That is, the upper rectangular cylinder portion 50a has an opening on the lower side Hd and is generally gate-shaped when viewed from the front, and the lower rectangular cylinder portion 50b has an opening on the upper side Hu and is generally gate-shaped when viewed from the front.

[0068] In addition, when the rectangular tube portion 50 is divided into the upper rectangular tube portion 50a and the lower rectangular tube portion 50b, the fitting rib 52 and the positioning rib 53 are also divided into two. That is, the fitting rib 52 is composed of a first fitting rib 52a and a second fitting rib 52b provided on the upper rectangular tube portion 50a, and the positioning rib 53 is composed of a first positioning rib 53a and a second positioning rib 53b provided on the upper rectangular tube portion 50a.

[0069] The intermediate curved portion 60 is a cylindrical body that is generally arc-shaped in plan view and curves to the right side Wr as it approaches the outlet side Lb, and is configured to allow the harness 10 to be inserted therein. In detail, the intermediate curved portion 60 is configured with an intermediate cylindrical portion 61 that is a curved cylindrical portion, a first restricting rib 62 that is disposed on the side surface on the left side Wl, and a second restricting rib 63 that is disposed on the side surface on the right side Wr.

[0070] The intermediate cylindrical portion 61 is a cylindrical body whose cross section perpendicular to the insertion direction of the harness 10 has a generally rectangular shape with chamfered corners. The first regulating rib 62 is a rib that protrudes from the central part of the intermediate tubular portion 61 in the height direction H toward the left side Wl, and is provided continuously from the end on the rectangular tubular portion 50 side to the end on the tubular portion 70 side.

[0071] The end face of the connecting side La of the first restricting rib 62 is provided so as to face the fitting rib 52 provided on the first cylindrical portion 51, and protrudes from the intermediate cylindrical portion 61 toward the left side Wl by a length substantially equal to the length from the inner edge of the lower chord rib 361 at the end of the lower side Hd of the upward lead-out portion 33 to the outer edge of the extension wall portion 334. The end of the left side Wl of the first restricting rib 62 is provided with a first restricting protrusion 64 that protrudes toward the fitting rib 52.

[0072] The first regulating projection 64 is formed in a substantially rectangular shape when viewed from the connecting side La, and protrudes toward the connecting side La by a length equal to the length along the insertion direction L of the lower side wall portion 343. Note that a gap of a length substantially equal to the sum of the plate thickness of the upper side Hu of the lower side wall portion 343 and the inner diameter of the upper chord rib 362 is provided between the first regulating projection 64 and the first cylindrical portion 51.

[0073] The second regulating rib 63 is a rib that protrudes from the central part of the height direction H of the intermediate tubular portion 61 toward the right side Wr, and is provided continuously from the end portion on the rectangular tubular portion 50 side to near the end portion on the intermediate curved portion 60 side of the tubular portion 70.

[0074] The end face of the connecting side La of the second restricting rib 63 is arranged to face the fitting rib 52 provided on the first cylindrical portion 51, similar to the first restricting rib 62. And, it protrudes toward the right side Wr by a length substantially equal to the length from the inner edge of the lower chord rib 361 at the end of the lower side Hd to the outer edge of the extension wall portion 334. In addition, the end of the second restricting rib 63 on the right side Wr is provided with a second restricting protrusion 65 that protrudes toward the fitting rib 52.

[0075] The second restricting projection 65 is formed in a substantially rectangular shape when viewed from the connecting side La, and protrudes toward the connecting side La by a length equal to the length along the insertion direction L of the lower side wall portion 343. Note that a gap of a length substantially equal to the sum of the plate thickness of the upper side Hu of the lower side wall portion 343 and the inner diameter of the upper chord rib 362 is provided between the second restricting projection 65 and the first cylindrical portion 51.

[0076] The intermediate curved portion 60 thus configured is divided into two in the height direction H, similar to the rectangular tube portion 50. Here, in the assembled state, the upper side Hu is the upper curved portion 60a, and the lower side Hd is the lower curved portion 60b (see FIG. 7(b)). That is, the upper curved portion 60a has an opening on the lower side Hd and is generally gate-shaped in front view, and the lower curved portion 60b has an opening on the upper side Hu and is generally gate-shaped in front view. The first restricting rib 62 and the second restricting rib 63 are provided at the end of the lower curved portion 60b on the opening side.

[0077] The tubular portion 70 is composed of a second tubular portion 71, which is a straight tubular body along the insertion direction of the harness 10, and three engagement ribs 72 protruding from the inner surface of the second tubular portion 71. The second cylindrical portion 71 is a generally rectangular cylindrical body that is one size larger than the outer diameter of the exterior material 20, and extends from the intermediate cylindrical portion 61 by a length approximately five times the distance between the large diameter portions 21.

[0078] The locking rib 72 is a rib that protrudes from the inner peripheral surface of the second cylindrical portion 71 and forms a through hole that is substantially circular in front view and has an inner diameter substantially equal to the outer diameter of the small diameter portion 22 . The locking ribs 72 configured in this manner are arranged side by side at intervals approximately equal to the intervals between adjacent large diameter portions 21, from the end portion opposite the intermediate curved portion 60 toward the intermediate curved portion 60. The locking rib 72 provided at the end portion opposite the intermediate curved portion 60 of the second cylindrical portion 71 is flush with the end portion opposite the intermediate curved portion 60 of the second cylindrical portion 71.

[0079] The above-mentioned tubular portion 70 is divided into two in the height direction H, similar to the rectangular tubular portion 50 and the intermediate curved portion 60. More specifically, the tubular portion 70 is composed of an upper tubular portion 70a and a lower tubular portion 70b connected via a hinge 80 and a connecting locking portion 90. Here, in the assembled state, the upper side Hu is the upper tubular portion 70a, and the lower side Hd is the lower tubular portion 70b (see FIG. 7(b)). That is, the upper tubular portion 70a has an opening on the lower side Hd and is generally gate-shaped when viewed from the front, and the lower tubular portion 70b has an opening on the upper side Hu and is generally gate-shaped when viewed from the front.

[0080] When the tubular portion 70 is divided into the upper tubular portion 70a and the lower tubular portion 70b, the locking rib 72 is also divided into two parts. That is, the locking rib 72 is composed of a first semicircular arc rib 72a provided on the inner circumferential surface of the upper tubular portion 70a and a second semicircular arc rib 72b provided on the inner circumferential surface of the lower tubular portion 70b.

[0081] In an assembled state in which the upper and lower cylinder portions 70a, 70b are assembled, the hinge 80 connects an upper end of the left side Wl of the upper cylinder portion 70a to a lower end of the left side Wl of the lower cylinder portion 70b in a manner that allows the hinge 80 to freely open and close. The connecting and locking portion 90 is disposed on the side opposite to the hinge 80, and is composed of a locking arm 91 and a connecting and locking frame 92 which lock with each other in an assembled state.

[0082] When assembled, the locking arm 91 is composed of a convex flat plate portion 911 that protrudes from the right side Wr of the upper cylindrical portion 70a toward the lower cylindrical portion 70b, and a claw portion 912 that protrudes outward from the outer surface of the flat plate portion 911. The connecting locking frame 92 is a frame body having a rectangular insertion space into which the locking arm 91 can be inserted when viewed in a plane in the assembled state, and is configured so that the claw portion 912 can be locked by inserting the flat plate portion 911 therethrough.

[0083] As described above, the connecting member 40, which is made up of the rectangular tube portion 50, the intermediate curved portion 60, and the tube portion 70, is made up of the upper connecting member 40a, which is an integrated combination of the upper rectangular tube portion 50a, the upper curved portion 60a, and the upper tube portion 70a, and the lower connecting member 40b, which is an integrated combination of the lower rectangular tube portion 50b, the lower curved portion 60b, and the lower tube portion 70b. The upper connecting member 40a and the lower connecting member 40b are configured to be freely opened and closed via the hinge 80 provided on the tube portion 70, and can be maintained in a closed state via the connecting locking portion 90.

[0084] Next, an assembly process for assembling the harness 10, the exterior material 20, the connecting connector 30, and the connecting member 40 to configure the harness routing structure 1 will be briefly described. First, one side of the harness 10 leading out from the lead-out portion 32 is inserted into the exterior material 20 via the slit 23. Next, the locking arm 91 and the connecting locking frame 92 are released to open the connecting member 40 up and down, and the harness 10 exposed from the exterior material 20 on the side of the connecting connector 30 of the exterior material 20 is placed along the lower connecting member 40b, and the exterior material 20 is fitted into the lower tubular portion 70b. At this time, the small diameter portions 22 of the exterior material 20 through which the harness 10 has been inserted are fitted into the three second circular arc ribs 72b arranged in parallel, respectively.

[0085] Then, the upper connecting member 40a is closed relative to the lower connecting member 40b via the hinge 80, and the locking arm 91 is locked with the connecting locking frame 92. This allows the harness 10, a portion of which is inserted into the exterior material 20, to be housed in the connecting member 40. In addition, the three first circular arc ribs 72a arranged in parallel are fitted into the small diameter portion 22, allowing the connecting member 40 to hold the exterior material 20 (see FIG. 8(a)).

[0086] Next, the rectangular tube portion 50 constituting the connecting member 40 accommodating the harness 10 is placed in the downward lead-out portion 34. More specifically, the second fitting rib 52b is placed in a position corresponding to the lower fitting recess 382 formed between the upper chord ribs 362, and the second positioning rib 53b is placed in a position corresponding to the lower accommodating portion 392 formed between the upper chord rib 362 and the lower partition portion 372, and the rectangular tube portion 50 is moved toward the downward lead-out portion 34.

[0087] Here, the plate thickness of the second fitting rib 52b is configured to be equal to the interval between the upper chord ribs 362 (annular rib 36). Therefore, the second fitting rib 52b can be fitted into the lower fitting recess 382 formed between the upper chord ribs 362.

[0088] The second positioning rib 53b is provided with a protrusion 54 that protrudes in the insertion direction L by the same amount as the plate thickness of the positioning rib 53. Therefore, the length of the second positioning rib 53b along the insertion direction L is approximately twice the plate thickness of the second fitting rib 52b. Furthermore, the length in the insertion direction L of the lower accommodating portion 392 formed between the upper chord rib 362 and the lower partition portion 372 is approximately twice the distance between the upper chord ribs 362 (annular ribs 36). Therefore, the second positioning rib 53b can be fitted into the lower accommodating portion 392 (see FIG. 8(b)).

[0089] On the other hand, since the length of the second positioning rib 53b along the insertion direction L is approximately twice the plate thickness of the second fitting rib 52b, the second positioning rib 53b cannot be inserted into the lower fitting recess 382. This makes it possible to prevent the rectangular tube portion 50 from being fitted into the annular rib 36 at any position other than the predetermined position. In addition, since the corners of the second fitting rib 52b and the second positioning rib 53b are chamfered, they can be easily inserted into the lower fitting recess 382 and the lower accommodating portion 392.

[0090] In this way, the second fitting rib 52b and the second positioning rib 53b are inserted and fitted into the lower fitting recess 382 and the lower accommodating portion 392, and then the upper lead-out portion 33 is assembled to the downward lead-out portion 34. This allows the first fitting rib 52a to be fitted into the upper fitting recess 381 formed between the lower chord ribs 361 in the upper lead-out portion 33, and the second positioning rib 53b to be fitted into the upper accommodating portion 391 formed between the lower chord rib 361 and the upper partition portion 371.

[0091] Furthermore, in a state where the downward lead-out portion 34 is assembled to the upper lead-out portion 33, the first and second restricting protrusions 64 and 65 are disposed so as to abut against the step portion 322 (see FIGS. 8(a) and 9(a)). If the rectangular tube portion 50 is inverted in the height direction H and fitted to the lead-out portion 32, the first and second restricting protrusions 64 and 65 abut against the extension wall portion 334, and therefore the downward lead-out portion 34 cannot be assembled to the upper lead-out portion 33. This makes it possible to prevent the rectangular tube portion 50 from being assembled to the lead-out portion 32 in the wrong direction.

[0092] Therefore, the rectangular tubular portion 50, through which the harness 10 led out from the lead-out portion 32 passes, is fitted onto the lead-out portion 32 so that the outer casing 20 is in the desired position, and the outer casing 20 is held by the tubular portion 70, thereby manufacturing the harness routing structure 1 (see FIG. 8(a)).

[0093] The harness routing structure 1 configured in this manner can electrically connect the electrical component Z and the harness 10 by connecting the interlocking connector 30 to the connector connection portion Z1 (see Figs. 1 and 2). In this manner, the harness routing structure 1 connected to the electrical component Z curves the routing direction of the harness 10 to the right side Wr via the intermediate curved portion 60 that is curved in a plan view. In other words, the routing direction of the harness 10 is curved so that the exterior material 20 does not interfere with the bracket B or the exterior pipe G.

[0094] Here, at the joint between the lead-out portion 32 and the rectangular tube portion 50, the fitting rib 52 and the positioning rib 53, which are configured to have a substantially rectangular shape when viewed from the front, are fitted into the first fitting groove 38 and the second fitting groove 39. Therefore, the outer peripheral surfaces of the fitting rib 52 and the positioning rib 53 are in surface contact with the inner peripheral surfaces of the first fitting groove 38 and the second fitting groove 39, which are formed to have a substantially rectangular shape (see FIG. 9(b)). Therefore, even if an unintended external force acts on the exterior material 20 or the connecting member 40, it is possible to restrict the rectangular tube portion 50 (connecting member 40) from unintendedly rotating relative to the connecting connector 30. Therefore, it is possible to prevent the exterior material 20 from rotating and interfering with the bracket B or the exterior pipe G.

[0095] As described above, the fitting rib 52 and the positioning rib 53 are fitted into the first fitting groove 38 formed by the adjacent annular rib 36 and the second fitting groove 39 formed by the annular rib 36 and the partition wall 37. This also restricts the rectangular tubular portion 50 from moving along the insertion direction L. This prevents the connection portion between the tubular portion 70 and the exterior material 20 from moving unintentionally, thereby reliably preventing the exterior material 20 from interfering with other members.

[0096] The harness routing structure 1 thus configured includes the harness 10, a flexible exterior material 20 that exteriorizes the harness 10, a connecting connector 30 having an outlet portion 32 from which the harness 10 is led out, and a connecting member 40 through which the harness 10 led out from the outlet portion 32 is inserted and which connects the exterior material 20 to the outlet portion 32. The connecting member 40 is hard, and a first fitting groove 38, a second fitting groove 39, a fitting rib 52, and a positioning rib 53 that regulate the connecting direction of the exterior material 20 to the outlet portion 32 are provided at a joint portion that joins the connecting member 40 and the outlet portion 32.

[0097] The connecting member 40 is provided with a rectangular tubular portion 50 which joins the outlet portion 32 of the connecting connector 30 from which the harness 10 is led out, a flexible tubular portion 70 which joins the outer casing 20 through which the harness 10 led out from the outlet portion 32 is inserted, and a hard intermediate curved portion 60 which is disposed between the rectangular tubular portion 50 and the tubular portion 70 and through which the harness 10 led out from the outlet portion 32 is inserted, and the rectangular tubular portion 50 is provided with an engaging rib 52 and a positioning rib 53 which regulate the connection direction of the outer casing 20 to the connecting connector 30.

[0098] This makes it possible to prevent interference between the exterior material 20 that exteriors the harness 10 and other members such as peripheral devices disposed around the routing path of the harness 10, even if an unintended external force is applied. More specifically, the first fitting groove 38, the second fitting groove 39, the fitting rib 52, and the positioning rib 53 are provided at the joint between the lead-out portion 32 and the exterior material 20 and the hard connecting member 40 that connects the lead-out portion 32 and the exterior material 20, so that the connecting direction of the exterior material 20 to the lead-out portion 32 can be regulated in a state where the end of the exterior material 20 on the lead-out portion 32 side (hereinafter simply referred to as the end of the exterior material 20 on the connecting member 40 side) is positioned at a desired location. This allows the connecting connector 30 and the exterior material 20 to be connected with the exterior material 20 facing in a desired direction with respect to the lead-out portion 32, so that even if an unintended external force such as vibration acts, interference between the exterior material 20 and other members such as the bracket B can be suppressed.

[0099] In addition, the direction in which the harness 10 is led out from the lead-out portion 32 is defined as the lead-out side Lb, and the connecting member 40 has an intermediate curved portion 60 that bends in a direction intersecting the lead-out side Lb. The first fitting groove 38, the second fitting groove 39, the fitting rib 52, and the positioning rib 53 regulate the rotation of the connecting member 40 relative to the connecting connector 30 around an axis along the lead-out side Lb as the rotation center.

[0100] As a result, by having the intermediate curved portion 60, the end portion of the exterior material 20 on the side of the connecting member 40 can be positioned in a direction away from the bracket B. In addition, since the connecting member 40 having the intermediate curved portion 60 and the lead-out portion 32 are joined via the first fitting groove 38, the second fitting groove 39, the fitting rib 52, and the positioning rib 53, it is possible to restrict rotation of the connecting member 40 relative to the lead-out portion 32. In other words, interference between the exterior material 20 and the bracket B can be further suppressed.

[0101] In addition, a rectangular tubular portion 50 that is configured in a rectangular shape when viewed from the lead-out side Lb is provided at the joint portion of the connecting member 40, and the rectangular tubular portion 50 is configured to be able to be externally fitted to the joint portion of the lead-out portion 32, and the rectangular tubular portion 50 (the engaging rib 52 and the positioning rib 53) and the lead-out portion 32 (the first engaging groove 38 and the second engaging groove 39) abut circumferentially, thereby regulating the rotation of the connecting member 40 relative to the connecting connector 30.

[0102] As a result, by fitting the rectangular tubular portion 50 of the connecting member 40 onto the lead-out portion 32, rotation at the joint portion between the connecting member 40 and the lead-out portion 32 can be restricted. More specifically, the rectangular tubular portion 50 of the connecting member 40 is fitted onto the lead-out portion 32 in a manner capable of restricting rotation, so that the rectangular tubular portion 50 (the fitting rib 52 and the positioning rib 53) and the lead-out portion 32 (the first fitting groove 38 and the second fitting groove 39) come into contact in the circumferential direction. Therefore, the other of the connecting member 40 and the lead-out portion 32 resists rotation of one of the connecting member 40 and the lead-out portion 32. Therefore, even if the connecting member 40 and the lead-out portion 32 attempt to rotate relative to the lead-out side Lb, the relative rotation of the lead-out portion 32 with respect to the rectangular tubular portion 50 can be restricted.

[0103] In addition, the rectangular tubular portion 50 has an engaging rib 52 and a positioning rib 53 that protrude in a rectangular shape when viewed from the lead-out side Lb, and the inner surface of the lead-out portion 32 is configured in a rectangular shape when viewed from the lead-out side Lb. The outer surfaces of the engaging rib 52 and the positioning rib 53 abut against the inner surface of the lead-out portion 32 in the circumferential direction, thereby regulating rotation of the connecting member 40 relative to the connecting connector 30.

[0104] According to this, the outer surfaces of the fitting ribs 52 and the positioning ribs 53 provided on the rectangular tubular portion 50 abut against the inner surface of the lead-out portion 32 in the circumferential direction, so that the lead-out portion 32 can be restricted from rotating relative to the rectangular tubular portion 50. Therefore, rotation can be reliably restricted with a simple structure.

[0105] In addition, the rectangular tube portion 50 has a shape in which the corners are chamfered when viewed from the lead-out side Lb. This makes it possible to improve the insertability of the rectangular tube portion 50 into the lead-out portion 32 (the lower lead-out portion 34) and to reliably restrict the rotation of the connecting member 40.

[0106] In addition, the mating rib 52 and the positioning rib 53 are arranged at a predetermined interval along the lead-out side Lb, and two first mating grooves 38 that can matingly engage with the mating rib 52 are arranged side by side along the lead-out side Lb on the inner surface side of the lead-out portion 32, and a second mating groove 39 that can accommodate the positioning rib 53 is provided on the side of the connector body 31 of the first mating groove 38, and the distance between adjacent first mating grooves 38 is different from the distance between the mating rib 52 and the positioning rib 53.

[0107] According to this, since the interval between the first fitting grooves 38 is different from the interval between the fitting rib 52 and the positioning rib 53, when the positioning rib 53 is inserted into the first fitting groove 38, the fitting rib 52 does not enter the first fitting groove 38 and interferes with the inner surface of the lead-out portion 32. This makes it possible to prevent incorrect assembly when assembling the connecting member 40 and the lead-out portion 32 by externally fitting them together.

[0108] In this embodiment, the convex portion 54 is provided on the positioning rib 53, and the interval between the fitting rib 52 and the positioning rib 53 is designed to be an integer multiple of the interval between the first fitting grooves 38. However, this is not limiting, and in the case where the convex portion 54 is not provided, the interval between the fitting rib 52 and the positioning rib 53 may be, for example, 1.2 times or 1.5 times the interval between the first fitting grooves 38, avoiding an integer multiple.

[0109] In addition, the mating rib 52 and the positioning rib 53 are arranged at a predetermined interval, and a first mating groove 38 capable of mating with the mating rib 52 is provided on the inner surface side of the lead-out portion 32, and a second mating groove 39 capable of accommodating the positioning rib 53 is provided on the connector body 31 side of the first mating groove 38, and the positioning rib 53 having the protrusion 54 has a thickness in the insertion direction L greater than the width of the first mating groove 38.

[0110] This makes it possible to prevent the positioning rib 53 from fitting into the first fitting groove 38, thereby preventing incorrect assembly when assembling the connecting member 40 and the lead-out portion 32 by fitting them from the outside.

[0111] Moreover, the exterior material 20 is formed of a corrugated tube in which small diameter portions 22 and large diameter portions 21 are alternately formed at predetermined intervals along the longitudinal direction, and the outlet portion 32 is configured so that the large diameter portion 21 can be fitted therein. As a result, the outlet portion 32 is formed so that the large diameter portion 21 of the corrugated tube can be fitted therein, and therefore the connecting member 40 can be connected to the connecting connector 30 configured so that the corrugated tube can be connected. Therefore, a highly versatile harness arrangement structure 1 can be configured.

[0112] Furthermore, the connecting member 40 which is the joint with the lead-out portion 32 is provided with a first restricting protrusion 64, a second restricting protrusion 65 and an extension wall portion 334 which restrict the assembly direction of the rectangular tube portion 50 and the lead-out portion 32. This makes it possible to prevent incorrect assembly when assembling the rectangular tube portion 50 and the lead-out portion 32, and also makes it possible to connect the coupling connector 30 and the exterior material 20 with the exterior material 20 facing in a desired direction relative to the lead-out portion 32.

[0116] Furthermore, the first fitting groove 38, the second fitting groove 39, the fitting rib 52, and the positioning rib 53 are configured to restrict the rotation of the exterior material 20 relative to the connecting connector 30 and also restrict the movement of the exterior material 20 along the insertion direction L, but are not limited to this. For example, they may restrict only the rotation of the exterior material 20 relative to the connecting connector 30, or may restrict only the movement of the exterior material 20 along the outlet side Lb of the harness 10 led out from the outlet 321.

[0117] Further, the first fitting groove 38, the second fitting groove 39, the fitting rib 52, and the positioning rib 53 are configured to restrict rotation via a contact surface at the joint between the connecting member 40 and the lead-out portion 32. However, the present invention is not limited to this configuration, and may be configured to restrict rotation of the exterior material 20 relative to the connecting connector 30 by, for example, engaging the connecting member 40 with the lead-out portion 32.

[0118] Furthermore, the positioning rib 53 is provided with a protrusion 54. That is, the positioning rib 53 is designed so that a portion of the thickness thereof is larger than the width of the first fitting groove 38, but, for example, the entire thickness of the positioning rib 53 may be larger.

[0119] In addition, in this embodiment, the lead-out portion 32 is configured to fit around the rectangular tube portion 50, but the rectangular tube portion 50 may be configured to fit around the lead-out portion 32. In this case, the rectangular tube portion 50 is provided instead of the lead-out portion 32, and the lead-out portion 32 is provided instead of the rectangular tube portion 50.
