DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fixing structure for a long member, which can reduce the amount of deformation even if vibration such as bending and stretching is applied to a wire harness of an automobile and can quickly reduce the initial shape. The present invention relates to a fixing structure for a long member that can be restored to a normal state.

[0002]

2. Description of the Related Art As shown in FIG. 7, a wire harness 71 in which a large number of various electric wires are bundled is often fixed to a vehicle body 70 of an automobile by a substantially C-shaped fixing member 72.

[0003]

However, when such a wire harness 71 is fixed over the vehicle body 70 and the engine 73, for example, the wire harness 71 is caused by the vibration of the engine 73 with respect to the vehicle body 70. The straddling portion 74 bends and stretches (see the chain line in the figure), and there is a possibility that each internal wire may be broken due to fatigue. The present invention has been made in view of the aforementioned problems,
The purpose is that when a long member such as a wire harness is straddled over a pair of mounting surfaces that relatively vibrate, bending and stretching deformation occurring in the long member can be reduced and the initial shape can be quickly restored. An object of the present invention is to provide a fixing structure for a measuring member.

[0004]

According to the present invention, there is provided a fixing portion extending in a direction intersecting the mounting surface for fixing a bendable elongate member to the mounting surface. And a holding portion capable of holding the long member, and connecting means for interconnecting the fixing portion and the holding portion, wherein the connecting means is a horizontal engaging pin, and the engaging pin is inserted and engaged. A possible slot, wherein the slot is inclined with respect to a horizontal plane.

Here, the long member in the present invention includes, for example, various hoses and outer tubes of wires, in addition to the above-mentioned wire harness. The mounting surface does not need to be a flat surface, but may be an arc surface such as upward, downward, or sideways, a curved surface, or a spherical surface.

[0006] Further, the fixing portion is provided upright from the mounting surface.
A hanging member, a horizontally arranged plate member, a rod-shaped member, or the like can be employed. Such a fixing portion may be integrally formed with a plate-shaped mounting member which is in abutment with the mounting surface and which is detachable by bolting or the like, or may be provided directly on the mounting surface. On the other hand, the holding portion may be formed, for example, in a substantially C-shape capable of gripping the long member, or may be formed in a band shape along the longitudinal direction of the long member. Then, such a holding portion may hold the elongate member by co-winding an insulating tape or the like in a state of being in close contact with the side surface of the elongate member.

The engaging pin may have any cross-sectional shape as long as it can slide in the long hole, and a flange may be formed integrally or separately at the tip. Furthermore, if the slot is inclined with respect to the horizontal plane,
Any of arc shapes may be selected. As the connection means, an engagement pin may be provided on one of the fixed portion and the holding portion, and an elongated hole may be provided on the other of the fixed portion and the holding portion. It is.

[0008] In the fixing structure of the long member configured as described above, since the holding portion is connected to the fixing portion extending in the cross direction of the mounting surface via the horizontal engaging pin, the long member is fixed. When an external force is applied along the radial direction of the member, the holding portion can swing about the engagement pin. Also, since the retaining pin is inserted and engaged with the elongated hole,
When an external force is applied along the longitudinal direction of the elongate member, the elongate member can relatively move with respect to the fixing portion, that is, the mounting surface. At this time, since the long hole is inclined with respect to the horizontal plane, when the external force applied along the longitudinal direction of the long member is eliminated, the engagement pin moves to the lowest position of the long hole due to its own weight of the holding portion. Will move.

Therefore, in the fixing structure of the elongated member, for example, when fixing the wire harness laid over the vehicle body and the engine, the lowermost position of the elongated hole is determined in advance by the initial position of the engaging pin. So that
If the fixed part and the holding part are positioned relative to each other, the amount of deformation can be reduced by swinging or moving the holding part with respect to the fixed part in response to engine vibration, and the wire harness is always restored to the initial shape. Such a force acts, which can reduce the possibility of the wire harness being disconnected due to fatigue.

Further, in the present invention, the long hole may have an arc shape. Here, the long hole provided in the fixing portion may be formed so that the curved vertex projects downward, and the long hole provided in the holding portion may be formed such that the curved vertex projects upward. I just need. In this structure for fixing the long member, since the long hole is arc-shaped, for example, if it is formed in the fixing portion so that the curved vertex protrudes downward, the engagement along the inner surface facing the arc center of the long hole. The pin is guided in a curved manner, so that the operation of the holding portion with respect to the fixing portion can be smoothed.

Further, according to the present invention, a pair of the engaging pins and the long holes are provided, and the respective engaging pins and the long holes are respectively arranged in plane symmetry. It is characterized by having. In this structure for fixing the long member, the holding portion is supported at two points with respect to the fixing portion, so that the holding portion can swing or move stably with respect to the fixing portion.

Further, according to the present invention, as described in claim 4, the holding portion has a substantially C section capable of accommodating the long member.
A first holding portion and a second holding portion each having a U-shape.
The holding portion and the second holding portion may be interconnected along the same axis, and a slit may be formed along a circumferential direction therebetween.

Here, the first holding portion and the second holding portion may be integrally formed of a suitable synthetic resin or the like, or may be separate members connectable via a suitable connection member. Is also good. In such a fixing structure of a long member, if one of the first holding portion and the second holding portion is bent and deformed along the long member, the holding member co-winds the long member with an insulating tape or the like. The work can be easily performed, and the long member can be reliably held on the holding portion.

According to the present invention, the thickness of the second holding portion may be smaller than the thickness of the first holding portion. In this structure for fixing the long member, since the first holding portion having a smaller thickness than the second holding portion can obtain desired flexibility, the first holding portion and the second holding portion are integrally formed. You can do it.

Further, in the present invention, the second holding portion may be provided at both ends in the axial direction of the first holding portion, for example, as compared with the first holding portion. If the flexibility of the second holding portion is high, the long member can be held substantially linearly.

On the other hand, the present invention is characterized in that, as described in claim 7, a break is provided in the elongated hole, and the engaging pin can pass through the break. Here, as the break portion, for example, a cut from the end surface of the fixing portion formed in a plate shape to the long hole may be formed. The broken portion may be provided so as to reach a surface of the pair of inner surfaces along the longitudinal direction of the elongated hole which faces the guide surface on which the engagement pin is pressed by the weight of the holding portion.

In this structure for fixing the long member, a breakable portion through which the engaging pin can pass is provided in the long hole.
For example, even if a stopper collar is integrally formed at the tip of the engagement pin, the engagement pin can be easily engaged with the elongated hole by passing through the breakage portion, whereby the fixing portion and the holding portion are formed. Can easily be assembled and disassembled.

Further, according to the present invention, as set forth in claim 8, the connecting means is such that the engaging pin is projected from an outer surface of the holding portion, and the elongated hole is formed in the fixing portion. It is characterized in that it is formed so as to penetrate the provided wall member in the thickness direction, and to have a curved vertex projecting downward.

Further, according to the present invention, as set forth in claim 9, the connecting means is arranged such that the engaging pin is provided on the fixing portion, and the elongated hole projects from the outer surface of the holding portion. It is characterized in that it is formed so as to penetrate in the thickness direction through a plate member provided and continuous in the longitudinal direction and to have a curved vertex projecting directly upward.
