Description

  The present invention relates to a component mounting structure, for example, a tube mounting structure that is an exterior material of a harness routed in a vehicle.

  Conventionally, various harnesses are routed in a vehicle. The path of some harnesses is regulated while being protected from other parts by inserting a section that may interfere with other parts into the tube (see, for example, Patent Documents 1 and 2). As described in FIG. 3 of Patent Document 1 or FIG. 2 of Patent Document 2, the tube that protects the harness is usually fixed to other parts on the vehicle body side by a clip.

  Regarding the attachment of the clip to the tube, there is no specific description in Patent Document 1, and a state in which the tube is simply passed through the tube portion of the clip is described (see FIG. 3, paragraph 0033). Patent Document 2 describes a configuration in which a large number of convex portions are arranged at a predetermined pitch in the axial direction on the outer surface of the tube, and the clip mounting position can be changed by allowing the annular wall of the clip to be inserted into each convex portion. (See FIG. 2, paragraph 0015).

  In the tube mounting structure described in Patent Document 1, if the clip is fixed so as not to move with respect to the tube, the positioning becomes difficult due to the variation in the arrangement position of the bracket for fixing the clip, and the tube or harness may not be routed. was there.

  In order to cope with such a problem, it is conceivable to mount the clip so that the position of the clip can be adjusted with respect to the tube. However, in this case, there is a possibility that the clip is likely to fall out of the tube before or after the tube is attached to the vehicle body side component, and the work efficiency is impaired. Such a problem is also conceivable in the tube mounting structure described in Patent Document 2.

  Further, in the tube mounting structure described in Patent Document 2, the position of the clip can be adjusted with respect to the tube, but the adjustment requires a considerable force for repeatedly engaging and disengaging the convex portion and the groove, and is not easy. In addition, the tube needs to be formed with a large number of convex portions on the outer surface, and the existing tube material cannot be used, resulting in a high cost.

  The present invention has been made paying attention to the problems of the conventional techniques as described above. A clip for fixing a linear or tubular part without lowering the work efficiency or increasing the cost. An object of the present invention is to provide a component mounting structure that facilitates position adjustment and enables reliable and efficient mounting of components.

  The present invention has been developed to achieve the above-described object, and a component mounting structure according to one aspect of the present invention includes a clip for mounting a linear or tubular mounting component to a mounted component, and a mounting component. The clip is mounted so as to be movable in the axial direction of the attachment component, and the movement range is limited by the stopper.

  According to the component mounting structure of the present invention, it is possible to easily adjust the position of a clip for fixing a component without lowering the work efficiency and increasing the cost, and the component can be securely and efficiently mounted.

It is the rear view seen from the back of the attachment structure of the tube which concerns on one Embodiment of this invention. It is a perspective view which expands and shows the state which attached the clip to the edge part of the tube which concerns on one Embodiment of this invention so that a movement was possible.

  Hereinafter, a mounting structure for mounting parts according to an embodiment of the present invention will be described with reference to the drawings. First, the attachment component is a linear or tubular component that extends continuously in the axial direction, such as a harness, a cable, a tube, or a pipe. Such attachment parts are not limited to linearly extending parts, and may be curvedly extending parts. Further, the attachment component does not necessarily have to have rigidity that cannot be deformed.

  FIG. 1 and FIG. 2 show an application example to a tube (attachment part) which is an exterior material of a headlamp harness in a vehicle such as a truck. In front of the driver's seat in the vehicle, a pair of headlamps arranged on the left and right of the vehicle are provided, and a harness for the headlamp is routed. FIG. 1 shows a state in which the head lamp 1 on the right side of the vehicle (RH) is viewed from the rear, and the left side of the vehicle (LH) (not shown) basically has a symmetrical structure with FIG. In FIG. 1, the upper side of the vehicle is indicated by an arrow of UPR.

  As shown in FIG. 1, a frame-shaped headlamp stay 2 is fixed to a vehicle body side part (attached part), and a housing 3 of the headlamp 1 is attached thereto. Related parts such as a lamp that is a light source and a motor that electrically adjusts the optical axis of the lamp are disposed in the housing 3, and a harness 10 is extended from the housing 3. A part of the section extending in the axial direction of the harness 10 is routed while being inserted through the tube 20.

  The tube 20 is an exterior material for restricting movement in the middle of the harness 10 and arranging and routing the harness 10. Therefore, the tube 20 is formed in a tubular shape whose inner diameter is larger than the outer diameter of the harness 10 by a material having a hardness higher than that of the harness 10. The harness 10 is a wire harness in which a plurality of cables are inserted into an exterior material such as a corrugated tube. The cable in the harness 10 is an electric wire group in which a plurality of electric wires used for power supply and signal communication are bundled together.

  The harness 10 illustrated in FIG. 1 includes a trunk line 11 in which a plurality of cables are bundled, and a branch line 12 branched from the middle of the trunk line 11. The trunk line 11 of the harness 10 supplies power to the lamp described above, and the branch line 12 supplies power to the motor. The harness 10 (the trunk line 11) is routed along the upper end portion of the headlamp stay 2 so as to extend in the left-right direction of the vehicle, and is then bent halfway downward and extended obliquely downward. In addition, although illustration was abbreviate | omitted, the connector which can connect a some electric wire at once to the edge part of the harness 10 is provided.

  The specific routing layout of the harness 10 is determined based on the relative positional relationship with other structural components arranged around the harness 10. The harness 10 in the present embodiment is routed to a fixed position extending linearly through the tube 20 by being inserted into the tube 20 over a predetermined section from a portion bent downward in the middle thereof. Has been. Although not shown, the dump cable is routed so as to extend in the vertical direction close to the tube 20 at the rear of the part where the tube 20 is attached to the vehicle body side part (the front side in FIG. 1). Yes. The dump cable is a power transmission cable for lifting the loading platform by lever operation at the driver's seat.

  The tube 20 regulates the routing route of the harness 10 in order to prevent interference between the dump cable routed behind it and the harness 10. Although the trajectory of the dump cable can fluctuate within a certain range, the provision of the tube 20 can ensure a gap between the harness 10 and the dump cable so as not to interfere with each other.

  The mounting structure of the tube 20 (attachment component) includes a clip 30 for attaching the tube 20 to a predetermined location of the housing 3 (attachment component) in addition to such a tube 20. The tube 20 is formed into a tubular shape from a material such as hard synthetic resin, and has an inner diameter larger than the outer diameter of the harness 10. In the harness 10, the portion inserted into the tube 20 may be reduced in diameter as compared with other portions.

  The total length of the tube 20 is determined according to, for example, the maximum fluctuation range of the dump cable described above, and a predetermined portion in the axial direction is attached to the housing 3 by the clip 30. Here, the clip 30 is mounted so as to be movable in the axial direction of the tube 20, and the movement range is limited by a stopper 40 described later provided on the tube 20.

  The clip 30 for attaching the tube 20 is not limited to one, and may be two or more. In this case, each clip 30 attaches the tube 20 to the housing 3 at at least two positions spaced from each other in the axial direction of the tube 20. Further, when there are two or more clips 30 to which the tube 20 is attached, at least one of them is mounted so as to be movable in the axial direction of the tube 20 and the movement range is limited by the stopper 40 provided on the tube 20. It ’s enough.

  In the present embodiment, both ends of the tube 20 in the axial direction are a pair of clips 30A and 30B (corresponding to the clip 30 described above. The clips 30A and 30B are hereinafter collectively referred to as the clip 30). Is attached through). One clip 30 </ b> A is fixed in advance to one end portion (upper end side in FIG. 1) of the tube 20. The other clip 30B is mounted so as to be movable in the axial direction on the other end (the lower end side in FIG. 1) side of the tube 20. The movement range of the other clip 30 </ b> B is limited by a later-described stopper 40 provided at the other end of the tube 20.

  The clip 30 includes a portion where the elastic band is bent in an annular shape and the tube 20 is externally fitted, and a base portion where the base end of the band is connected and fixed to the housing 3. The base portion has a through-hole through which the band passes, and the band can be tightened by engaging the serrated irregularities on one side of the band in the through-hole.

  The base portion of the clip 30 is formed in a dish shape with a material that can be elastically deformed when pressed against the housing 3. A shaft protrudes from the center of the dish-shaped portion, and a locking blade is provided at the tip of the shaft to prevent the shaft from coming off when the shaft is fitted into the locked hole on the housing 3 side. Depending on the degree of tightening of the band of the clip 30, the clip 30 can be fixed so as not to move in the axial direction of the tube 20, or the clip 30 can be mounted so as to be movable in the axial direction of the tube 20.

  On the other hand, a bracket 4 is fixed in advance at a location where the clip 30 on the housing 3 side is fixed. The bracket 4 is provided with a locking hole (not shown) for fitting the locking blades of the clip 30 on the wall surface with which the dish-like portion serving as the base of the clip 30 comes into contact. Such an arrangement of the brackets 4 is determined at a specific position in the housing 3 in principle although there is a tolerance. The clip 30 is used not only to attach the tube 20 but also to directly fix each part of the harness 10 to the housing 3.

  A pair of stoppers 40 that restrict the movement range of the clip 30 at the other end of the tube 20 are provided so as to be separated from each other and restrict the movement range of the clip 20 therebetween. That is, the stopper 40 is provided at the end of the other end portion of the tube 20, and is separated from the first stopper 40 </ b> A to the center side with respect to the first stopper 40 </ b> A that prevents the clip 30 from moving out of the other end portion of the tube 20. And a second stopper 40B that prevents the clip 30 from moving toward the center of the tube 20 (hereinafter, the first stopper 40A and the second stopper 40B are collectively referred to as the stopper 40). is there.).

  The movement range of the portion of the band attached to the tube 20 by the clip 30 is limited between the first stopper 40A and the second stopper 40B. Each of the stoppers 40A and 40B is provided so as to protrude from the reference surface on the outer periphery of the tube 20 in the circumferential direction so as to contact the side end surface of the annularly curved band.

  The stopper 40 can be provided by, for example, winding a belt-shaped thick tape around the outer periphery of the tube 20. Thus, when the stopper 40 is retrofitted as a separate body to the outer periphery of the tube 20, an existing general hard tube can be used as it is. The stopper 40 may be integrally formed as an annular ridge on the outer periphery of the tube 20.

  As described above, according to the mounting structure of the tube 20 according to the present embodiment, the tube 20 inserted through the harness 10 is attached to the housing 3 via the clip 30. At this time, each clip 30 is fixed to each bracket 4 fixed to the housing 3 in advance. For example, first, the clip 30A fixed to one end of the tube 20 is fixed to the bracket 4 and positioned.

  As for a method of fixing the clip 30A to one end of the tube 20, for example, a vinyl tape or the like is wound around the outer periphery of the tube 20, and a band of the clip 30 is externally fitted on the vinyl tape or the like and tightened firmly. Thereby, even if it does not use an adhesive agent etc., it can fix so that clip 30A may not move easily with respect to the tube 20 by the normal condition of the force with respect to clip 30A.

  Next, the clip 30 </ b> B that is movable at the other end of the tube 20 is fastened while being matched with the bracket 4. Since the clip 30B is movable in the axial direction of the tube 20, even if there is a variation in the distance between the bracket 4 for fastening the clip 30A and the bracket 4 for fastening the clip 30B due to tolerances, the clip 30A and the clip 30B The interval can be easily adjusted.

  The movement range of the clip 30 </ b> B is limited by the first stopper 40 </ b> A provided at the end of the other end portion of the tube 20, and there is no fear that the clip 30 </ b> B comes off from the other end of the tube 20. Further, the moving range of the clip 30 </ b> B is limited by the second stopper 40 </ b> B provided to be separated from the first stopper 40 </ b> A toward the center side, and the clip 30 </ b> B does not move too much to the one end side of the tube 20. Therefore, the distance moved when adjusting the position of the clip 30B is small. Note that the moving range of the clip 30B, that is, the interval between the first stopper 40A and the second stopper 40B only needs to be set to exceed the tolerance of the interval between the brackets 4.

  In the present embodiment, the two end portions of the tube 20 are attached to the housing 3 side via the clip 30 as the two locations separated from each other in the axial direction of the tube 20, so that the attachment strength and stability are improved. By inserting the harness 10 through such a tube 20, the positional accuracy when routing the harness 10 in a limited space in the vehicle is improved. Further, the harness 10 can be protected from other components (such as the dump cable), and a gap can be secured so as not to interfere with other components.

  The embodiments of the present invention have been described above with reference to the drawings. However, the specific configuration is not limited to the above-described embodiments, and the present invention can be changed or added without departing from the scope of the present invention. Included in the invention. For example, in the above-described embodiment, the tube 20 that is the exterior material of the harness 10 of the headlamp 1 in the vehicle has been described as an attachment component. However, the present invention is not limited to the vehicle headlamp but is applicable to linear or tubular parts of various products. Can be applied. For example, the present invention can be applied to a member extending continuously in the axial direction, such as a rod or a frame material, as a kind of linear component.

  Further, in the above-described embodiment, the two locations on both ends of the tube 20 are each attached to the housing 3 via the two clips 30. However, the number of the locations where the tube 20 is attached and the number of the clips 30 are limited to two. 1 or 3 or more may be sufficient. Further, the illustrated clip 30 is merely an example, and as another clip, for example, one portion in the circumferential direction of a tubular portion is divided by a slit extending in the axial direction so that the slit expands and contracts by elastic deformation. It may be configured. In such a clip, the clip can be easily fitted in the middle of the tube 20 (between each stopper) by pushing the slit open.

  Furthermore, in the above-described embodiment, only one clip 30B of the two clips 30 attached to both ends of the tube 20 can be moved. In particular, when it is not necessary to position the other clip 30A, The clip 30A may also be movably attached to the end portion of the tube 20 in the same manner as the clip 30B.

  The mounting structure for mounting parts according to the present invention is suitable for mounting a tube as an exterior material of a harness routed in a vehicle, but can be widely applied to mounting various mounting parts used for things other than vehicles. is there.
