Description

[Technical field]

[0001] The present invention relates to a connection structure for holding parts, and more particularly to a connection structure for holding parts that mutually connect two holding parts capable of holding two elongated members, respectively. [Background technology]

[0002] Conventionally, two holding parts (combined clips) for holding two long members (e.g., wire harnesses) at a fixed distance from each other are already known. Here, the following Patent Document 1 discloses a technique for connecting two holding parts so that they can rotate relative to each other. Therefore, even if there is a misalignment in the routing paths of the two long members held at a fixed distance, the two holding parts can rotate relative to each other to follow the misalignment. Therefore, compared to a case in which the two holding parts cannot rotate relative to each other, the misalignment in the routing paths of the two long members can be tolerated. [Patent Document 1] Patent No. 3314115 Summary of the Invention [Problem to be solved by the invention]

[0003] However, in the above-mentioned conventional technology, for example, the connecting shaft that connects the two holding parts so that they can rotate relative to each other may become distorted due to an external force acting from the two long members, and therefore the two holding parts cannot be smoothly rotated relative to each other.

[0004] The present invention has been made in consideration of the above circumstances, and the problem that the present invention aims to solve is to provide a connecting structure for holding parts that allows two holding parts to rotate smoothly relative to each other. [Means for solving the problem]

[0005] One feature of the present disclosure is a connection structure that connects two holding parts each capable of holding two elongated members. A cylindrical anchor having an engagement claw is formed in one of the two holding parts. An engagement hole is formed in the other of the two holding parts, into which the anchor of one of the holding parts can be inserted and the engagement claw can be engaged with the hole edge. In an engagement state of the two holding parts in which the engagement claw of the anchor of one of the holding parts is engaged with the hole edge of the engagement hole of the other holding part, the two holding parts are relatively rotatable around an axis whose axial direction is the insertion direction. The two holding parts are provided with a twist prevention mechanism that prevents twisting of the anchor of one of the holding parts when the two holding parts are engaged.

[0006] Therefore, even if an external force is applied from the two elongated members, the anchor that rotatably connects the two holding parts to each other does not become distorted, and therefore the two holding parts can rotate smoothly relative to each other.

[0007] Another feature of the present disclosure is that the other holding component includes a seat body having the engagement hole formed in a seat surface thereof, and an opening is formed in the seat body for disengaging the engagement claw from the hole edge of the engagement hole.

[0008] Therefore, the engagement between the two holding parts can be released without damaging the engaged portions of the two holding parts.

[0009] Another feature of the present disclosure is that the anti-twist mechanism is configured such that, when the two retaining parts are engaged, a support post formed on one retaining part penetrates into the anchor of the other retaining part, and the outer wall of the penetrated support post is in close proximity to the inner wall of the anchor.

[0010] Therefore, if the anchor becomes distorted due to external forces acting from the two long members, the outer wall of the post and the inner wall of the anchor immediately come into contact. This makes it possible to prevent the two holding parts from becoming distorted with a simple structure.

[0011] Another feature of the present disclosure is that the anti-twist mechanism is configured such that, when the two retaining parts are in an engaged state, a receiving wall formed on the other retaining part is in close proximity to an outer wall of the anchor of one retaining part.

[0012] Therefore, if the anchor becomes distorted due to external forces acting from the two long members, the receiving wall of the other holding part and the outer wall of the anchor immediately come into contact. Therefore, it is possible to prevent the two holding parts from becoming distorted with a simple structure.

[0013] In another feature of the present disclosure, the support column and the receiving wall of the other holding component are formed in a support part formed inside the base body, and a notch is formed in the edge of the support part on the side where the opening is formed.

[0014] Therefore, for example, when inserting a finger into the opening of the seat body to release the engagement between the two holding parts, the finger can be easily inserted into the opening of the seat body, and therefore the engagement between the two holding parts can be easily released.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the present invention will be described with reference to Figures 1 to 18. First, the overall configuration of two holding parts 1 and 2 (first holding part 1 and second holding part 2) according to the embodiment of the present invention will be described.

[0017] First, the first holding component 1 will be described (see Figs. 1 to 7). The first holding component 1 is composed of a base body 10 and a holding body 20. The base body 10 is configured in a substantially U-shape with a pair of walls 12 and a seat portion 13 bridging the pair of walls 12 so as to have an insertion space 11 therein. A support portion 14 is formed in the insertion space 11 of the base body 10 so as to bridge the pair of walls 12. The support portion 14 is formed with an elastic engagement piece 14a.

[0018] An engagement claw 14b is formed on the engagement piece 14a. A cylindrical anchor 15 is formed to protrude from the seat portion 13 of the seat body 10. An elastic engagement piece 15a is formed on the anchor 15 via a substantially U-shaped notch 16. An engagement claw 15b is formed on the engagement piece 15a. The engagement pieces 15a with the engagement claws 15b are formed to face each other in pairs.

[0019] The holding body 20 is composed of a substantially semicircular first curved portion 21 extending from the base body 10, and a substantially semicircular second curved portion 23 whose base end is connected to the tip of the first curved portion 21 via a hinge 22. The substantially semicircular arc shapes of the first curved portion 21 and the second curved portion 23 are formed to correspond to the arc shape of the outer diameter of the first wire harness 40 to be held. An engagement piece 24 is formed at the tip of the second curved portion 23.

[0020] The engagement piece 24 is formed with a first engagement claw 24a and a second engagement claw 24b in this order from the tip. The first engagement claw 24a corresponds to (is used to hold) the first wire harness 40 having a large diameter, and the second engagement claw 24b corresponds to the first wire harness 40 having a small diameter. The first engagement claw 24a and the second engagement claw 24b are capable of engaging with the engagement claw 14b by bending the engagement piece 14a. The base body 10 and the holding body 20 are integrally formed from a synthetic resin having rigidity. The first holding part 1 is configured in this manner.

[0021] The holding body 20 of the first holding component 1 configured in this manner can hold the first wire harness 40 by bending the hinge 22 to engage the first engagement claw 24a or the second engagement claw 24b of the engagement piece 24 with the engagement claw 14b of the seat body 10. When the first wire harness 40 has a large diameter, the first engagement claw 24a of the engagement piece 24 can be engaged with the engagement claw 14b of the seat body 10. When the first wire harness 40 has a thin-large diameter, the second engagement claw 24b of the engagement piece 24 can be engaged with the engagement claw 14b of the seat body 10.

[0022] Next, the second holding part 2 will be described (see Figs. 1 to 7). The second holding part 2, like the first holding part 1, is composed of a base body 30 and a holding body 20. Note that since the holding body 20 of this second holding part 2 has the same configuration as the holding body 20 of the first holding part 1 already described, the same reference numerals are used in the drawings to avoid redundant description. Also, the first engagement claw 24a of the holding body 20 of this second holding part 2 corresponds to the second wire harness 50 with a large diameter, and the second engagement claw 24b corresponds to the second wire harness 50 with a small diameter.

[0023] The base body 30 is configured in a substantially U-shape with a pair of walls 32 and a seat portion 33 bridging the pair of walls 32 so as to have an insertion space 31 inside. The base body 30 is formed with an opening 30a for disengaging each engagement claw 15b of the anchor 15 from the hole edge of an engagement hole 36, which will be described later. In the insertion space 31 of the base body 30, a first support portion 34 and a second support portion 35 are formed at a distance from each other so as to bridge the pair of walls 32.

[0024] The first support portion 34 is formed with an elastic engagement piece 34a. The engagement piece 34a is formed with an engagement claw 34b. The second support portion 35 is formed with a cross-shaped support 35a protruding toward the engagement hole 36. The outer diameter of the support 35a is set to be slightly smaller than the inner diameter of the anchor 15 (see FIG. 15). The second support portion 35 is also formed with a pair of auxiliary walls 35c protruding from the wall portion 32 so as to face each other across the support 35a.

[0025] A receiving wall 35d is formed at the tip of each of the pair of auxiliary walls 35c. Therefore, the support pillar 35a and the receiving wall 35d are formed in the second support portion 35. The opposing distance between the receiving walls 35d is set to be slightly larger than the outer diameter of the anchor 15 (see FIG. 15). A notch 35e is formed in the edge of the second support portion 35 on the side where the opening 30a of the base body 30 is formed.

[0026] An engagement hole 36 into which the anchor 15 of the first holding component 1 can be inserted is formed in the seat surface 33a of the seat portion 33 of the seat body 30. The seat body 30 and the holding body 20 are integrally formed from a synthetic resin having rigidity. The second holding component 2 is thus configured.

[0027] The holding body 20 of the second holding component 2 configured in this manner can hold the second wire harness 50 by bending the hinge 22 to engage the first engagement claw 24a or the second engagement claw 24b of the engagement piece 24 with the engagement claw 14b of the seat body 10. When the second wire harness 50 has a large diameter, the first engagement claw 24a of the engagement piece 24 can be engaged with the engagement claw 14b of the seat body 10. When the second wire harness 50 has a thin-large diameter, the second engagement claw 24b of the engagement piece 24 can be engaged with the engagement claw 14b of the seat body 10.

[0028] Next, the engagement operation between the first holding part 1 and the second holding part 2 will be described (see Figs. 8 to 14). First, the anchor 15 of the first holding part 1 is inserted relatively into the engagement hole 36 of the second holding part 2. Then, the engagement claws 15b of the anchor 15 interfere with the inner circumferential surface of the engagement hole 36. As a result, the engagement pieces 15a of the anchor 15 bend in directions approaching each other. Eventually, the engagement claws 15b of the anchor 15 climb over the inner circumferential surface of the engagement hole 36.

[0029] Then, the deflection of each engaging piece 15a of anchor 15 is released, and each engaging piece 15a of anchor 15 from which the deflection has been released engages with the hole edge of engaging hole 36 (see FIG. 16). As a result, first holding part 1 and second holding part 2 are brought into an engaged state. This description corresponds to the "engaged state of two holding parts" described in the claims.

[0030] In this engaged state, the first holding part 1 and the second holding part 2 can rotate relative to each other around an axis in the axial direction of the anchor 15. For example, Fig. 17 shows a state in which the first holding part 1 and the second holding part 2 are rotated 90 degrees relative to each other. Also, Fig. 18 shows a state in which the first holding part 1 and the second holding part 2 are rotated 180 degrees relative to each other. Of course, the first holding part 1 and the second holding part 2 can also be rotated 360 degrees relative to each other.

[0031] In addition, in this engaged state, the support 35a of the second holding part 2 enters the anchor 15 of the first holding part 1. Therefore, the outer wall 35b of the entered support 35a is in close proximity to the inner wall 15c of the anchor 15 (see FIG. 15). Note that this engaged state in which the receiving wall 35d of the support 35a enters close proximity to the inner wall 15c of the anchor 15 corresponds to the twist prevention mechanism 60.

[0032] In addition, in this engaged state, the pair of receiving walls 35d of the second holding component 2 is in close proximity to the outer wall 15d of the anchor 15 of the first holding component 1 (see FIG. 15). Note that, in this engaged state, the pair of receiving walls 35d is in close proximity to the outer wall 15d of the anchor 15, which corresponds to the twist prevention mechanism 60. As is clear from these descriptions, the first holding component 1 and the second holding component 2 are provided with the twist prevention mechanism 60.

[0033] To disengage the first holding part 1 and the second holding part 2, a finger (not shown) is inserted through the opening 30a of the base body 30 to bend the engagement piece 15a of the anchor 15. This disengages the engagement claw 15b of the anchor 15 from the edge of the engagement hole 36. This allows the anchor 15 to be pulled out of the engagement hole 36. This allows the engagement to be disengaged without damaging the engagement portion between the first holding part 1 and the second holding part 2.

[0034] The connection structure of the first holding part 1 and the second holding part 2 according to the embodiment of the present invention is configured as described above. With this configuration, in the engaged state of the first holding part 1 and the second holding part 2, the first holding part 1 and the second holding part 2 can rotate relative to each other around the axis of the anchor 15. In addition, the first holding part 1 and the second holding part 2 are provided with a twist prevention mechanism 60. Therefore, even if an external force acts from the first wire harness 40 and the second wire harness 50, the anchor 15 that connects the first holding part 1 and the second holding part 2 to be rotatable relative to each other does not twist. Therefore, the first holding part 1 and the second holding part 2 can rotate relative to each other smoothly.

[0035] Moreover, according to this configuration, the base body 30 is formed with an opening 30a for disengaging the engagement claws 15b of the anchor 15 from the edge of the engagement hole 36. Therefore, the engagement between the first holding part 1 and the second holding part 2 can be released without damaging the engagement portion.

[0036] Also, according to this configuration, the twist prevention mechanism 60 is configured such that, in an engaged state between the first holding component 1 and the second holding component 2, the support 35a of the second holding component 2 enters the anchor 15 of the first holding component 1, and the outer wall 35b of the entered support 35a is in close proximity to the inner wall 15c of the anchor 15. Therefore, when twisting occurs in the anchor 15 due to an external force acting from the first wire harness 40 and / or the second wire harness 50, the outer wall 35b of the support 35a immediately comes into contact with the inner wall 15c of the anchor 15. Therefore, twisting of the first holding component 1 and the second holding component 2 can be prevented with a simple structure.

[0037] Furthermore, according to this configuration, the twist prevention mechanism 60 is configured by the receiving wall 35d of the first holding component 1 being in close proximity to the outer wall 15d of the anchor 15 of the first holding component 1 when the first holding component 1 and the second holding component 2 are in an engaged state. Therefore, when twisting occurs in the anchor 15 due to an external force acting from the first wire harness 40 and / or the second wire harness 50, the receiving wall 35d of the second holding component 2 and the outer wall 15d of the anchor 15 immediately come into contact with each other. Therefore, twisting of the first holding component 1 and the second holding component 2 can be prevented with a simple structure.

[0038] Furthermore, according to this configuration, the support pillar 35a and the receiving wall 35d of the second holding component 2 are formed in the second support portion 35. A notch 35e is formed in the edge of the second support portion 35 on the side where the opening 30a of the seat body 30 is formed. Therefore, when inserting a finger into the opening 30a of the seat body 30 to release the engagement between the first holding component 1 and the second holding component 2, the finger can be easily inserted into the opening 30a of the seat body 30. Therefore, the engagement between the first holding component 1 and the second holding component 2 can be easily released.

[0039] The connection structure of the first holding part 1 and the second holding part 2 according to the embodiment of the present invention is not limited to the above-described embodiment, and may be configured by modifying appropriate portions as follows: The two long members are not limited to the first wire harness 40 and the second wire harness 50, and may be two hoses, etc.

[0040] In addition, in the first holding part 1, the first wire harness 40 is held by the first curved part 21 and the second curved part 23, but this is not limited thereto, and the first wire harness 40 may be held (clamped) by a belt, a substantially U-shaped protector, a substantially rectangular protector, etc. The same applies to the second holding part 2.
