Hereinafter, the clip and the fixing structure according to the present embodiment will be described with reference to the attached drawings. The same parts are designated by the same reference numerals, and their names and functions are also the same. Therefore, detailed explanations about them will not be repeated.

FIG. 1 is a schematic perspective view showing a fixed structure 1 provided with a clip 10 according to the present embodiment.

As shown in FIG. 1, the fixed structure 1 of the present embodiment is used to fix and hold a distribution body such as a wire harness arranged to a vehicle or the like with respect to a vehicle body frame. Specifically, the fixed structure 1 includes a fixed member 2 such as a vehicle body frame, and a clip 10 for fixing and holding a distribution body (not shown) to the fixed member 2. In FIG. 1, for convenience of explanation, a part of the clip 10 (a part of the outer periphery of the tip portion 14B described later) is cut out and shown.

The fixed member 2 is, for example, a plate-shaped member, and a substantially circular through hole 3 on the fixed side is formed through the predetermined portion in the plate thickness direction. The hole diameter of the through hole 3 on the fixed side is not particularly limited, but is preferably substantially the same as the outer diameter of the base end portion 14A of the locking protrusion 14 described later, and the tip portion 14B of the locking protrusion 14 It is formed to have a smaller diameter than the outer diameter. Examples of the fixed member 2 include a side member extending in the front-rear direction of the vehicle, a cross member extending in the width direction of the vehicle, a floor panel of a cab, and the like.

The clip 10 is provided at one end of a band portion 11 formed of a thin plate curved in a substantially C-shaped cross section in the circumferential direction (longitudinal direction) of the band portion 11, and is a seat plate seated on the fixed member 2. A locking plate portion 13 provided at the other end of the portion 12 and the other end of the band portion 11 in the circumferential direction (longitudinal direction) and facing the seat plate portion 12, and from the locking plate portion 13 to the seat plate portion 12 side. It is provided with a locking protrusion 14 that projects toward it.

The band portion 11, the seat plate portion 12, the locking plate portion 13, and the locking protrusion portion 14 are preferably integrally formed of a resin material or the like, so that the band portion 11 is wound around the outer periphery of the control body. It can be curved and deformed. The band portion 11 may be curved in a C shape in advance, or may be a straight plate shape that is curved and deformed when wound around the steering body.

The seat plate portion 12 is formed in a substantially rectangular parallelepiped shape, and is preferably formed to be thicker than the band portion 11. Specifically, the connection portion between the seat plate portion 12 and the band portion 11 is formed so as to become thicker from the band portion 11 side toward the seat plate portion 12 side.

A substantially circular clip-side through hole 12A through which the locking protrusion 14 can be inserted is formed through the portion corresponding to the locking protrusion 14 of the seat plate portion 12 in the plate thickness direction. The hole diameter of the clip-side through hole 12A is not particularly limited, but is preferably formed to have substantially the same diameter as the fixed-side through hole 3, and is substantially the same as the outer diameter of the base end portion 14A of the locking protrusion 14, which will be described later. It is formed to have the same diameter and a smaller diameter than the outer diameter of the tip portion 14B of the locking protrusion 14.

The locking plate portion 13 is formed in a substantially rectangular parallelepiped shape having the same shape as the seat plate portion 12, and is preferably formed to be thicker than the band portion 11. The connection portion between the locking plate portion 13 and the band portion 11 is formed so as to become thicker from the band portion 11 side toward the locking plate portion 13 side. In this way, by making the band portion 11 thin and the locking plate portion 13 and the seat plate portion 12 thick, the band portion 11 can be easily deformed when wound around the control body, and the locking plate portion 11 can be easily deformed. Deformation of the portion 13 and the seat plate portion 12 can be effectively suppressed. By suppressing the deformation of the locking plate portion 13 and the seat plate portion 12, the operator can easily insert the locking protrusion portion 14 into the clip-side through hole 12A.

The locking protrusion 14 has a base end portion 14A and a tip end portion 14B in order from the locking plate portion 13 side. The base end portion 14A is preferably formed in a substantially columnar shape. The outer diameter of the base end portion 14A is preferably formed to be substantially the same as the hole diameter of each through hole 3, 12A, or slightly smaller than the hole diameter of these through holes 3, 12A. Further, the axial length t (protruding height from the locking plate portion 14) of the base end portion 14A is preferably a combination of the plate thickness t1 of the fixed member 2 and the plate thickness t2 of the seat plate portion 12. It is formed with substantially the same length as the total plate thickness (= t1 + t2).

That is, by setting the base end portion 14A of the locking protrusion 14 to have substantially the same diameter as the hole diameters of the through holes 3 and 12A, after the locking protrusion 14 is inserted, the locking plate portion 14 and the seat are used. It is possible to effectively prevent the plate portion 12 and the fixed member 2 from sliding (relatively moving) in the plane direction with each other. Further, by setting the protruding length of the base end portion 14A to be the same as the plate thickness of the fixed member 2 and the seat plate portion 12, the tip end portion 14B surely protrudes to the back surface side of the fixed member 2. While making it possible, the sliding (relative movement) of the clip 10 with respect to the fixed member 2 can be effectively suppressed.

The tip portion 14B is formed in a substantially truncated cone shape that tapers toward the protruding end. The outer diameter of the tip portion 14B on the base end portion 14A side is formed to be larger than the outer diameter of the base end portion 14A and the hole diameters of the through holes 3 and 12A, and penetrates each of the locking protrusions 14. When the tip portion 14B is inserted into the holes 3 and 12A and the tip portion 14B is projected toward the back surface side of the fixed member 2, the tip portion 14B presses against the back surface of the fixed member 2 to hold the clip 10 on the fixed member 2. You can do it. The tip portion 14B preferably has a hollow structure at least on the base end portion 14A side so that the tip portion 14B can be easily deformed when inserted into the through holes 3 and 12A. Specifically, the portion of the tip portion 14B on the proximal end portion 14A side is formed in a skirt shape having a larger diameter than the proximal end portion 14A, and contracts inward in the radial direction when inserted into the through holes 3 and 12A. While deforming in diameter, it expands outward in the radial direction when passing through the through holes 3 and 12A.

In the present embodiment, the protruding length of the base end portion 14A is formed to be the same as the plate thickness of the fixed member 2 and the seat plate portion 12, and each through hole 3 of the locking protrusion portion 14 is formed. , Even if the tip portion 14B is pressed against the back surface of the fixed member 2 by insertion into the base end portion 14A, it is possible to effectively prevent a large axial tension from acting on the base end portion 14A. The shape of the base end portion 14A is not limited to the truncated cone shape, and other shapes that can be locked to the back surface of the fixed member 2 such as a conical shape may be applied.

Next, the work of fixing the arrangement body 50 to the fixed member 2 using the clip 10 according to the present embodiment will be described with reference to FIGS. 2, 3 and 4.

Here, the clip 10 is used to fix and hold the arranging body 50 such as a wire harness arranged by a predetermined route to the fixed member 2. The arrangement body 50 is not limited to the wire harness, and may be long cables, cords, hoses, and other pipes. Further, the arrangement place of the arrangement body 50 is not particularly limited, and can be widely applied to plants such as vehicles, industrial machines, electronic devices, factories and power plants. In FIGS. 2, 3 and 4 below, the arranging body 50 is shown by a alternate long and short dash line for simplification.

First, as shown in FIG. 2, the band portion 11 of the clip 10 is wound around the outer periphery of the distribution body 50, the locking projection portion 14 is inserted into the clip-side through hole 12A, and the locking plate portion 13 is seated. Join with the portion 12. Next, as shown in FIG. 3, the tip portion 14B of the locking projection portion 14 protruding from the seat plate portion 12 is aligned with the fixed-side through hole 3. When the tip portion 14B is aligned with the fixed side through hole 3, as shown in FIG. 4, the locking plate portion 13 is pushed in the direction of the arrow in the drawing, and the seat plate portion 12 is seated on the fixed member 2. As a result, the fixing work of the arrangement body 50 is completed. At this time, since the base end portion 14A of the locking projection portion 14 is formed to have the same length as the plate thickness of the fixed member 2 and the seat plate portion 12, the operator can perform the locking plate portion 13. The tip portion 14B can be easily projected toward the back surface side of the fixed member 2 simply by pushing the tip portion 14B with a fingertip or the like.

According to the clip 10 of the present embodiment described in detail above, the band portion 11 that can be wound around the steering body 50, the seat plate portion 12 that sits on the fixed member 2, and the locking that is joined to the seat plate portion 12. It includes a plate portion 13, a clip-side through hole 12A that penetrates the seat plate portion 12 in the plate thickness direction, and a locking protrusion portion 14 that protrudes from the locking plate portion 13 toward the seat plate portion 12. The locking projection 14 has a base end portion 14A and a tip end portion 14B, and the protrusion length of the base end portion 14A from the locking plate portion 13 is a combination of the seat plate portion 12 and the fixed member 2. It is formed with the same length as the thickness.

As a result, the clip 10 is distributed after the locking projections 14 are inserted into the through holes 3 and 12A while the distribution body 50 is easily fixed and held to the fixed member 2 with a simple configuration. It becomes possible to effectively prevent sliding (relative movement) with respect to the measure 2. By suppressing the sliding of the clip 10, it is possible to surely improve the fixing property of the arranging body 50 with respect to the fixed member 2.

It should be noted that the present disclosure is not limited to the above-described embodiment, and can be appropriately modified and implemented without departing from the spirit of the present disclosure.

For example, the work of fixing the arrangement body 50 to the fixed member 2 using the clip 10 is not limited to the procedure shown in FIGS. 2 to 4 described above, and may be performed by the procedure shown in FIGS. 5 to 7.

Specifically, first, as shown in FIG. 5, by inserting the locking protrusion 14 into the fixed-side through hole 3, the clip 10 is previously fixed to the mating-side fixed member 2 and sub-assembled. I will do it. Next, as shown in FIG. 6, the band portion 11 is wound around the outer periphery of the arrangement body 50, and further, as shown in FIG. 7, the clip-side through hole 12A is formed in the locking protrusion portion 14 protruding from the fixed member 2. Is inserted, and the fixed member 2 is sandwiched between the locking plate portion 13 and the seat plate portion 12, so that the fixing work of the distribution body 50 is completed. In this way, if the clip 10 is sub-assembled to the mating member 2 on the other side in advance, it is possible to shorten the assembly work time on the production line.

Further, in the above embodiment, the hole diameter of the fixed-side through hole 3 and the hole diameter of the clip-side through hole 12A are both formed to have the same diameter as the outer diameter of the base end portion 14A of the locking projection portion 14. However, if the hole diameter of the fixed-side through hole 3 is the same as the outer diameter of the base end portion 14A, the hole diameter of the clip-side through hole 12A is formed to be larger than the outer diameter of the base end portion 14A. You may. Further, although the band portion 11 is formed thinner than the seat plate portion 12 and the locking plate portion 13, these can also be formed with the same wall thickness. The wall thickness of the band portion 11 may be appropriately set according to the type, diameter, and the like of the arrangement body 50.
