<Explanation of Embodiments of the present disclosure>
First, embodiments of the present disclosure will be listed and described.
The cable guide of the present disclosure is
(1) A pair of link frames arranged side by side in a row and rotatably connected to each other, and the link frames are separated from each other in an orthogonal direction orthogonal to the arrangement direction and face each other. Link plates, a bottom wall arranged between the base ends of the pair of link plates and connecting the base ends, and a bottom wall arranged between the tips of the pair of link plates and connecting the tips. The lid body has a pair of connecting portions that are detachably connected to the pair of the link plates via a locking mechanism, and each connecting portion faces the bottom wall. The outer wall and the inner wall are separated from each other in the orthogonal direction, and the tip end portion of the link plate is arranged between the outer wall and the inner wall. The lid is a cable guide provided with reinforcing ribs that extend continuously in the orthogonal direction and connect the pair of connecting portions.

According to the cable guide of the present disclosure, the lid is detachably connected to the pair of link plates via a lock mechanism. As a result, when the lid body is removed from the pair of link plates, the link frame body, which has conventionally been continuous in the circumferential direction, can be provided with an opening that opens toward the tip end side of the link plate. it can. Therefore, by removing the lid, a continuous opening in the length direction is secured in the insertion space of the wire harness formed by the internal spaces of the plurality of link frames being continuous in the alignment direction. As a result, the wire harness is easily inserted into the insertion space of the wire harness provided in the cable guide.

The lid body separated from the pair of link plates and separated from the lid has a double wall structure in which the connecting portion to the pair of link plates consists of an inner wall and an outer wall, and the pair of links between the inner wall and the outer wall. The tip of the plate is inserted. Therefore, even if a load is applied between the pair of link plates connected between the tips by the lid, the link plates are stably supported by the connecting portion of the double wall structure, and the strength of the link frame is increased. To be secured.

Since the lid is reinforced by the reinforcing ribs that extend continuously across the connecting portions, the risk of buckling of the lid when a load is input between the connecting portions is eliminated or reduced. .. In this way, even if the lid is separated from the pair of link plates, the decrease in strength with respect to the conventional tubular link frame is reduced or avoided, and the protection function of the wire harness and the like are sufficiently provided. It will be demonstrated.

(2) It is preferable that the bottom surface of the lid body facing the bottom wall of the link frame body is a flat surface, and the reinforcing ribs are provided on the top surface of the lid body.

Since the bottom surface of the lid that constitutes the wall surface of the insertion space of the wire harness is a flat surface, interference between the lid and the wire harness is prevented. The lid is reinforced by providing reinforcing ribs on the top surface of the lid.

(3) In the alignment direction, both edges of the lid may be formed thinner than the central portion of the lid, and the reinforcing ribs may be provided at the central portion of the lid.

By forming both edges of the lid that easily come into contact with the wire harness when the cable guide bends, the contact pressure of the lid against the wire harness is reduced, and the risk of damage to the wire harness is reduced. Will be done. By providing the reinforcing rib in the central portion of the lid, for example, one reinforcing rib can obtain a well-balanced reinforcing effect, and it is possible to avoid the generation of a moment due to the imbalance of rigidity.

(4) In the alignment direction, the central portion of the lid may be formed thinner than both edges of the lid, and the reinforcing ribs may be provided on both edges of the lid.

Reinforcing ribs are provided on both edges of the lid, where pressure from the wire harness tends to concentrate when the cable guide bends, preventing damage to the lid and improving the durability of the cable guide. ..

(5) It is preferable that the width dimension of the lid body is larger on the connecting portion side than the central portion in the orthogonal direction.

At the central portion of the lid, where pressure from the wire harness extending in a circular cross section is likely to be applied when the cable guide bends, the width dimension of the lid is smaller than that on the connecting portion side. Therefore, the concentration of the load is reduced when the wire harness is brought into contact with the lid body, and damage to the lid body is prevented and durability is improved.

(6) Each of the connecting portions of the lid body is provided with a lock insertion hole penetrating the outer wall, and the lock frame of the lock mechanism is formed by the outer wall that is bent and deformable by the lock insertion hole. Therefore, it is desirable that the lock claw of the lock mechanism is provided so as to project outward from the tip of each link plate in the orthogonal direction.

The lock mechanism is composed of a lock frame formed by the outer wall of the connecting portion and a lock claw protruding outward in the orthogonal direction from the tip end portion of the link plate. As a result, the lock mechanism is compactly provided while a large volume of the internal space of the link frame is secured.

Since the lock frame is formed by forming the lock insertion hole in the outer wall of the connecting portion, the deformation rigidity of the lock frame is reduced, and the lock frame is elastically deformed to easily get over the lock claw. Therefore, the lid body is easily connected to the link plate by the locking mechanism, and the lid body can be easily attached to the link plate.

(7) It is preferable that the inner wall and the outer wall of the lid have a width dimension that is the length dimension in the alignment direction, and the width dimension of the inner wall is smaller than the width dimension of the outer wall. ..

By reducing the width dimension of the inner wall that is inserted between the pair of link plates, interference between the link plate and the inner wall is less likely to occur when the cable guide is bent, and bending deformation of the cable guide is allowed with a greater degree of freedom. ..

By increasing the width dimension of the outer walls arranged on the outer side of the pair of link plates in the opposite direction, the outer walls are overlapped over a wider range of the link plates. Therefore, the reinforcement of the link plate by superimposing the outer walls is realized over a wide range.

(8) It is preferable that the pair of link plates are provided with a support portion for supporting the inner wall.

Since the inner wall of the lid is supported by a pair of link plate supports, the amount of deformation of the link plate and lid due to load input is limited, improving durability and avoiding interference with the wire harness. Be done.

The wire harness device of the present disclosure is
(9) A wire harness device including the cable guide according to at least one of (1) to (8) above and a wire harness housed in the cable guide.

According to the wire harness device of the present disclosure, in the wire harness device in which the wire harness is housed in the cable guide, the effect of the cable guide disclosed in at least one of the above (1) to (8) can be obtained. ..

<Details of Embodiments of the present disclosure>
A specific example of the cable guide of the present disclosure will be described below with reference to the drawings. It should be noted that the present invention is not limited to these examples, and is indicated by the scope of claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.

<Embodiment 1>
As shown in FIGS. 1 and 2, the cable guide 10 has a structure in which a plurality of link frames 12 arranged side by side in a row are rotatably connected to each other. The cable guide 10 extends by a predetermined length in the arrangement direction A of the plurality of link frames 12. The cable guide 10 is used as an exterior to a wire harness W bridged between a vehicle body (not shown) and a movable body such as a sliding door. As shown in FIG. 3, each link frame body 12 is composed of a base body 14 and a lid body 16.

The substrate 14 is an injection-molded product of a synthetic resin such as polypropylene or polyamide. The substrate 14 has a groove shape as a whole, and the pair of link plates 18 and 18 arranged so as to face each other in the orthogonal direction B orthogonal to the arrangement direction A and the base ends of the link plates 18 and 18. A bottom wall 22 that connects the 20s to each other is integrally provided.

The link plate 18 has a first plate 24 arranged on one side and a second plate 26 arranged on the other side in the arrangement direction A of the plurality of link frames 12. The first plate 24 and the second plate 26 are spread out so as to be displaced from each other in the orthogonal direction B, which is the thickness direction, and are integrally connected to each other. The link plate 18 composed of the first plate 24 and the second plate 26 has an offset structure in which a step portion 28 is formed at a connecting portion between the first plate 24 and the second plate 26.

In the link plate 18, the first plate 24 is located outside the second plate 26 in the orthogonal direction B. The inner surface of the first plate 24 extends in the same plane as the outer surface of the second plate 26.

The first plate 24 is formed with a connecting pin hole 30 penetrating in the orthogonal direction B. The first plate 24 is thickened at the peripheral edge of the opening of the connecting pin hole 30, and the deformation rigidity of the opening of the connecting pin hole 30 is ensured. The connecting pin hole 30 is not limited to the through hole, and may have a concave shape in which the outer opening is closed, for example. The second plate 26 is formed with a connecting pin 32 that projects outward in the orthogonal direction B. The inner peripheral surface of the connecting pin hole 30 and the outer peripheral surface of the connecting pin 32 have circular cross-sectional shapes corresponding to each other.

A support portion 34 is formed on the inner surfaces of the pair of link plates 18 and 18 in the opposite direction. That is, since the second plate 26 is offset inward with respect to the first plate 24, a step portion 28 is formed on the inner surfaces of the pair of link plates 18 and 18 in the opposite direction. By forming a notch in the stepped portion 28, a stepped support portion 34 is formed.

A lock claw 38 is provided on the tip portion 36 of the link plate 18. The lock claw 38 is integrally formed with the link plate 18 and projects outward in the orthogonal direction B. The lock claw 38 is an inclined surface in which both sides in the orthogonal direction B are inclined outward in the orthogonal direction B toward the base end portion 20 side. The lock claw 38 has a flat locking surface on the base end portion 20 side.

The pair of link plates 18, 18 have base end portions 20 connected to each other by a plate-shaped bottom wall 22. The bottom wall 22 is integrally formed with the pair of link plates 18, 18.

As shown in FIGS. 4 and 5, the lid body 16 has a plate shape and has a structure in which connecting portions 42 and 42 are provided on both sides of the lid wall portion 40. The lid body 16 has a different shape from the front surface on the top surface 46 side described later and the back surface on the bottom surface 44 side described later. The lid 16 is an injection-molded product of a synthetic resin such as polypropylene or polyamide. The lid 16 may be formed of the same material as the substrate 14, or may be formed of a material different from that of the substrate 14. For example, the lid 16 smaller than the substrate 14 is formed of a higher-strength material to improve durability, and the limited use of the high-strength material reduces the cost increase. obtain.

The lid wall portion 40 has a long plate shape extending in the orthogonal direction B. The bottom surface 44 of the lid wall portion 40 facing the bottom wall 22 of the substrate 14 is a flat surface. In the alignment direction A, a reinforcing rib 48 projecting from the top surface 46 is integrally formed at the center of the lid wall portion 40. The reinforcing rib 48 is a ridge extending linearly in the orthogonal direction B. In the lid wall portion 40, the thickness dimension of both edge portions off the reinforcing rib 48 in the arranging direction A is smaller than the thickness dimension of the central portion where the reinforcing rib 48 is formed. Since the reinforcing rib 48 is formed in the central portion of the lid wall portion 40, the reinforcing effect can be obtained in a well-balanced manner by one reinforcing rib 48.

The connecting portion 42 includes a top wall 50 extending parallel to the lid wall portion 40. The top wall 50 is formed with an outer wall 52 projecting at the outer end portion in the orthogonal direction B and an inner wall 54 projecting at the inner end portion in the orthogonal direction B. The reinforcing ribs 48 are continuously provided so as to be bridged between the pair of connecting portions 42, 42, and both ends of the reinforcing ribs 48 are connected to the top walls 50, 50 of the connecting portions 42, 42. .. The protruding tip surface of the reinforcing rib 48 extends on the same plane as the surface of the top walls 50 and 50 on the top surface 46 side.

The outer wall 52 has a plate shape that extends orthogonally to the top wall 50. The outer wall 52 has a base end portion connected to the top wall 50 protruding with a constant width dimension. The width of the tip of the outer wall 52 gradually decreases toward the protruding tip.

A lock insertion hole 56 is formed in the top wall 50 and the outer wall 52. The lock insertion hole 56 is formed in the central portion of the top wall 50 and the outer wall 52 in the alignment direction A, straddling the outer end portion of the top wall 50 in the orthogonal direction B and the base end portion of the outer wall 52. As a result, in the formed portion of the lock insertion hole 56, the cross sections of the top wall 50 and the outer wall 52 are reduced by the amount of the lock insertion hole 56, and the bending rigidity of the top wall 50 and the outer wall 52 is reduced. By forming the lock insertion hole 56 in the outer wall 52, the outer wall 52 constitutes a U-shaped lock frame 58 that is opened toward the top wall 50 side.

The inner wall 54 has a plate shape that extends parallel to the outer wall 52, and faces the outer wall 52 inward in the orthogonal direction B at a distance. The inner wall 54 projects from the top wall 50 with a certain width dimension. The outer surface of the protruding tip portion of the inner wall 54 is inclined inward toward the tip, and is thinned in the orthogonal direction B toward the protruding tip. The inner wall 54 is located inside the opening portion of the lock insertion hole 56 in the top wall 50 in the orthogonal direction B.

The lid 16 is attached to the substrate 14 as shown in FIGS. 6 and 7. That is, the tip portions 36 of the link plates 18 and 18 of the substrate 14 are inserted and arranged between the outer wall 52 and the inner wall 54 of each connecting portion 42. Then, the lock frames 58 of both outer walls 52 get over the lock claws 38 of both link plates 18, and both lock claws 38 are inserted into the two lock insertion holes 56 of the lid body 16. As a result, the separation of the base 14 and the lid 16 is restricted by the engagement (snap fit) between the lock claw 38 and the lock frame 58, and the locking mechanism that connects the pair of link plates 18 and 18 of the base 14 and the lid 16 is connected. 60 is configured. In the lock mechanism 60, the lock claw 38 is arranged in a housed state without protruding from the lock insertion hole 56, and a space-saving lock mechanism 60 is configured, and an unintended lock is released by the action of an external force. Hard to occur.

The lid 16 has a plane-symmetrical shape relating to a plane extending orthogonally to the alignment direction A at the center of the alignment direction A, and a plane-symmetrical shape relating to a plane extending orthogonally to the orthogonal direction B at the center of the orthogonal direction B. Has been done. Therefore, in the work of assembling the lid 16 to the base 14, only the front and back orientations of the lid 16 need to be aligned with the base 14. For example, even if the lid 16 with the correct front and back orientation is rotated 180 ° with respect to the base 14, the lid 16 is correctly assembled to the base 14. As described above, the mounting directionality of the lid 16 to the base 14 is reduced during the assembling work of the lid 16, and the lid 16 can be easily assembled to the base 14.

Since the outer surface of the protruding tip portion of the inner wall 54 is inclined inward toward the protruding tip, the tip portion 36 of the link plate 18 is easily guided between the inner wall 54 and the outer wall 52. Both sides of the lock claw 38 in the orthogonal direction B are inclined surfaces, and the lock claw 38 is thinned in the orthogonal direction B toward the lid 16 side. As a result, the lock claw 38 is easily guided between the inner wall 54 and the outer wall 52. A compact lock mechanism 60 is composed of a lock frame 58 formed by an outer wall 52 of the connecting portion 42 and a lock claw 38 protruding outward in the orthogonal direction B from the tip portion 36 of the link plate 18. As a result, a large volume of the internal space 62 described later of the link frame body 12 is secured.

The lock mechanism 60 detachably connects the base 14 and the lid 16. In a state where the base body 14 and the lid 16 are connected by the lock mechanism 60, an external force is applied to the lid 16 to bend and deform the outer wall 52 and the top wall 50. As a result, the engagement between the lock claw 38 and the tip end portion of the outer wall 52 is released, and the lid 16 can be removed from the base body 14.

Since the lock frame 58 is formed by the outer wall 52 of the connecting portion 42 in which the lock insertion hole 56 is formed, the rigidity of the lock frame 58 against bending deformation is reduced. Therefore, the lock frame 58 can easily get over the lock claw 38 while elastically flexing, and the connection work between the lid 16 and the link plates 18 and 18 becomes easy.

The lock insertion hole 56 is formed in the connecting portion 42 so as to penetrate not only the outer wall 52 but also the top wall 50. As a result, the deformation rigidity of the top wall 50 with respect to bending is also reduced, and the lock frame 58 can easily get over the lock claw 38 even by the elastic deformation of the top wall 50. Since the lock insertion hole 56 is opened between the outer wall 52 and the inner wall 54 in the top wall 50, the structure of the mold can be simplified when the lid 16 is formed.

By attaching the lid 16 to the link plates 18, 18 of the base 14, the lid wall portion 40 of the lid 16 is arranged between the tips 36, 36 of the pair of link plates 18, 18, and the side of the base 14 is arranged. The opening to the direction is covered by the lid 16. As a result, the tubular link frame body 12 is composed of the base body 14 and the lid body 16. As shown in FIGS. 6 and 7, the link frame body 12 is formed with an internal space 62 penetrating in the arrangement direction A.

The outer wall 52 and the inner wall 54 of the lid 16 are arranged so as to sandwich the tip 36 in a state of being overlapped with the tip 36 of the link plate 18, and are connected to the tip 36. As a result, the tip 36 of the link plate 18 is reinforced by the outer wall 52 and the inner wall 54, and the deformation rigidity is improved at the connecting portion between the lid 16 and the base 14.

The inner wall 54 of the lid 16 is supported by being overlapped with the support portion 34 of the link plate 18. As a result, the connecting portion 42 of the lid 16 and the link plate 18 are relatively positioned in the protruding direction of the inner wall 54. For example, even when the lid 16 is deformed by the action of a load or the lid 16 is displaced relative to the base 14, the inner wall 54 of the lid 16 is supported by the support portion 34, so that the lid 16 is supported. The deformation and displacement of 16 are limited. As a result, damage due to excessive deformation of the lid 16 is prevented, and damage to the wire harness W due to the lid 16 being pressed against the wire harness W is also prevented.

As shown in FIG. 5, the height dimension h, which is the protruding dimension of the inner wall 54 from the top wall 50, is smaller than the height dimension H, which is the protruding dimension of the outer wall 52 from the top wall 50. As a result, the reinforcing effect of the link plate 18 by the outer wall 52 can be exerted over a wide range while preventing the internal space 62 from being narrowed by the inner wall 54.

As shown in FIGS. 1 and 2, a plurality of the link frame bodies 12 are rotatably connected to each other in the arrangement direction A. That is, in the link frame bodies 12 and 12 adjacent to each other in the arrangement direction A, the connecting pin 32 of one link frame body 12 is inserted into the connecting pin hole 30 of the other link frame body 12. As a result, the link frames 12 and 12 adjacent to each other in the alignment direction A are connected to each other in a manner in which rotation within a predetermined angle range around the connecting pin 32 is permitted. In this way, the cable guide 10 is configured by connecting the plurality of link frames 12 so as to be rotatable with each other. The number of link frames 12 constituting the cable guide 10 is not particularly limited.

One end of the alignment direction A on the inner surface of the link plate 18 and the other end of the alignment direction A on the tip surface of the connecting pin 32 are inclined surfaces corresponding to each other. As a result, the connecting pin 32 can be easily inserted into the first plate 24 from one of the alignment directions A, and the work of inserting the connecting pin 32 into the connecting pin hole 30 is facilitated.

The cable guide 10 is bendable at a connecting portion between the link frame bodies 12 adjacent to each other in the arrangement direction A. The rotatable angle range of the plurality of link frame bodies 12 is that, for example, the end portion of the second plate 26 of one link frame body 12 hits the step portion 28 of the second plate 26 of the other link frame body 12. Specified by. Bending of the cable guide 10 may be permitted only on either one of the lid 16 side and the bottom wall 22 side, or may be permitted on both sides of the lid 16 side and the bottom wall 22 side.

As shown in FIG. 7, in the lid 16, the width dimension d (length dimension in the alignment direction A) of the inner wall 54 is smaller than the width dimension D (length dimension in the alignment direction A) of the outer wall 52. .. As a result, when the link frames 12 and 12 connected to each other rotate, the inner wall 54 of one link frame 12 is less likely to interfere with the link plate 18 of the other link frame 12, and they are less likely to interfere with each other. The link frame 12 is allowed to rotate to a larger angle. By ensuring a large width dimension D of the outer wall 52, the link plate 18 can be reinforced by the outer wall 52 over a wide range.

A wire harness W is inserted through the cable guide 10. The wire harness W has, for example, a shape in which a plurality of electric wires are bound by a binding member such as a tube or a band and extends in a substantially circular cross section. However, the wire harness W does not have to have a strictly circular cross section, as can be seen from the fact that the wire harness W is formed by bundling a plurality of electric wires. In the cable guide 10, an insertion space 64 is formed in which the internal spaces 62 of each link frame body 12 are arranged and continuous in the direction A, and the wire harness W is arranged in the insertion space 64. As a result, the periphery of the wire harness W is protected by the cable guide 10, and the bending deformation of the wire harness W is allowed by the bending of the cable guide 10. The plurality of electric wires constituting the wire harness W do not have to be bound by the binding member.

Since the bottom surface 44 of the lid 16 constituting the wall surface of the insertion space 64 is a flat surface, when the wire harness W housed in the insertion space 64 hits the bottom surface 44, stress concentration due to the unevenness of the bottom surface 44 is concentrated. This is avoided and the durability of the wire harness W is improved.

The wire harness W inserted through the cable guide 10 is arranged between the pair of link plates 18 and 18 of the base 14 before the lid 16 is attached to the base 14. For example, after the wire harness W is placed between the link plates 18 and 18 of each base 14 in a state where the plurality of bases 14 are connected to each other on the link plate 18, the link plates 18 and 18 of each base 14 are arranged. A lid 16 is attached to each. As a result, the cable guide 10 can insert the wire harness W into the insertion space 64 through the openings of the respective base bodies 14 which are continuous in the arrangement direction A which is the length direction of the cable guide 10. ing. Therefore, the work of inserting the wire harness W from one end to the other end of the cable guide 10 in the line-up direction A becomes unnecessary, and the work of inserting the wire harness W into the cable guide 10 becomes easy. In addition, since it is not necessary to insert the terminal provided at the end of the wire harness W into the inside of the cable guide 10, the cable guide 10 is externally attached to the wire harness W without damaging the terminal of the wire harness W. It becomes possible to do.

When the lid 16 is connected to the base 14, the inner wall 54 of the lid 16 is slid and moved with respect to the inner surface of the link plate 18 of the base 14 while being kept in close proximity. As a result, the wire harness W does not get caught between the link plate 18 and the inner wall 54, damage to the wire harness W is avoided, and the work of assembling the lid 16 to the base body 14 becomes easy.

Since the lock mechanism 60 is provided between the link plate 18 of the base 14 and the outer wall 52 of the lid 16, the lock mechanism 60 does not interfere with the wire harness W.

The lid 16 has a double wall structure in which the connecting portions 42, 42 of the base 14 to the pair of link plates 18, 18 are provided with an outer wall 52 and an inner wall 54, respectively, and the link plate is formed between the outer wall 52 and the inner wall 54. The tip 36 of 18 is inserted. Therefore, even if a load is applied in the orthogonal direction B which is the opposite direction of the pair of link plates 18 to the link frame body 12, the link plates 18 are reinforced by the connecting portion 42 of the double wall structure. , The load-bearing performance of the link frame body 12 is sufficiently ensured.

Specifically, for example, when the cable guide 10 is exteriorized by a wire harness W that connects the vehicle body and the electrical components of the sliding door, a person steps on the cable guide 10 and the load in the orthogonal direction B is applied to the cable. It may act on the guide 10.
