Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a molded protector for a linear body, and more particularly to a protector for accommodating a linear body such as a wire harness and adjusting the disposition posture of the linear body for protection.

[0002]

2. Description of the Related Art In recent years, a resin-molded protector has been widely used as a means for arranging and protecting a linear body such as an electric wire bundle for a vehicle or an optical fiber bundle or an air pipe bundle. . In particular, a harness protector (hereinafter, referred to as a protector) that disposes and protects a wire harness to be mounted in a vehicle needs to be securely attached so as to suppress an abnormal noise (vibration noise) due to vibration during traveling of the vehicle. .

A conventional protector mounting structure will be described in detail below with reference to the drawings. FIG. 3 shows a general mounting method of the protector 1 to the vehicle panel 5. As shown in FIGS. 3A and 3B, a separate clip 6 is attached to a tree stud bolt (hereinafter referred to as a stud bolt) 4 protruding from the surface of a vehicle panel 5 through a mounting hole 3 of a protector 1. , Fixed. When the mounting state is described in detail, as shown in FIG. 4A, when a separate clip 6 is used for fixing the protector 1, at least a region where the protector 1 comes into contact with the vehicle panel 5 is cushioned with urethane rubber or the like. The material was interposed as the insulator 7, and the clip 6 was pushed into the stud bolt 4 and locked. With such a structure, the rattling of the protector 1 due to the vibration during traveling of the vehicle is suppressed by the insulator 7,
The generation of abnormal noise is prevented. As a method of attaching the protector to the vehicle panel, there is a structure in which the clip is integrally molded with the protector in addition to the structure shown in FIG. 3, and the mounting situation in such a structure is shown in FIG. 4 (b). As shown, attach the stud bolt 4 to the clip 1'of the protector 1.
Is locked. In this case, the locking portion 6a of the clip portion 6 '
Is securely engaged with the stud bolt 4, and rattling of the protector 1 is suppressed.

[0004]

As described above, in the method of interposing the insulator, there is a problem that the number of man-hours for mounting the wire harness is increased, and in addition to the structure or the dimension, a portion where the insulator cannot be used is used. However, when the integrally molded clip cannot be used, there are many cases where no measures are taken to prevent the generation of abnormal noise. For example, when the protector is attached and fixed to a vehicle panel or the like by a separate clip, the fixing position of the clip 6 depends on the pitch b of the thread of the stud bolt 4 as shown in FIG. At the final fixing position of, the clearance a having a size smaller than the thread pitch b of the stud bolt 4 is formed between the protector 1 and the protector 1. That is, when the relation of a <b is satisfied, the protector 1 cannot be fixed any more by the clip 6, the rattle of the protector 1 occurs, and the abnormal noise is generated when the vehicle is running.

Further, as shown in FIG. 5A, when the A protector 1 and the B protector 1'in which the clip portion 6'is integrally formed are fixed (co-tightened) to the same stud bolt, as shown in FIG. As shown in (b), a gap a is formed between the B protector 1 ′ and the A protector 1 at the final fixing position, which causes a noise. As a method of solving such a problem, a nut for a stud bolt is used instead of the clip, which is a fixing means of the protector,
There is a method to prevent the clearance a by tightening this nut. However, the use of the nut increases the number of parts, and increases the number of man-hours for tightening the nut with an impact wrench or the like and lowers the work efficiency. However, it was not a fundamental solution.

[0006] An object of the present invention is to solve the above problems,
An object of the present invention is to provide a protector having a structure in which generation of abnormal noise is suppressed when the protector is mounted on a mounting surface. Particularly, in the invention of claim 1, the elastic means having the spring portion for ensuring the locking mechanism is provided in the vicinity of the locking structure by the stud bolt and the clip, thereby preventing the protector from rattling due to the vibration of the vehicle. The purpose is to provide a protector that

[0007]

In order to achieve the above-mentioned object, the invention according to claim 1 is a protector for accommodating a linear body, which is mounted and fixed to a bolt projecting from a predetermined mounting surface. A locking means that is locked to the bolt; and an elastic means that is provided in the vicinity of the fixed portion of the protector that is mounted and fixed by the locking means and that presses the locking means in a direction opposite to the mounting surface. It is characterized by that.

With such a structure, in the first aspect of the invention, the locking means (clip) which is locked to the bolt (stud bolt) by the elastic means (spring portion) provided in the vicinity of the locking and fixing portion of the protector. ) Is pushed back to the direction opposite to the mounting surface, the locking means is locked and fixed to the bolt with sufficient force.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail with reference to embodiments. FIG. 1 is a diagram showing an embodiment of a protector according to the present invention. In FIG. 1A, a seat surface portion for mounting on a vehicle panel or the like is formed at a predetermined portion of the protector 1, and a mounting hole 3 into which a stud bolt protruding from the mounting surface is inserted is opened in this seat surface portion. ing. The elastic means 2 is provided on the seat surface portion near the mounting hole 3. The shape of this elastic means has a spring portion 2a protruding toward the mounting surface side of the protector 1 as shown in a sectional view in FIG. Clip 6 has stud bolt 4
A locking portion 6a is formed that is inserted into the mounting thread in the mounting surface direction and is locked in the counter mounting surface direction (removal direction).

FIG. 2 shows the mounting state of the protector 1 as described above.
Shown in In FIG. 2A, first, the stud bolt 4 provided so as to project from the vehicle panel 5 is passed through the mounting hole 3 of the protector 1, and then the separate clip 6 is pushed in. By such mounting work, as shown in FIG. 2B, the spring portion 2a of the elastic means 2 is pressed by the mounting surface 5, and an elastic force is generated in the direction (arrow direction) for removing the clip 6 from the stud bolt 4. . Therefore, even if a gap a occurs between the protector 1 and the vehicle panel 5, the protector 1
Is the locking force between the clip 6 and the stud bolt 4, and the spring portion 2
The elastic force of “a” securely locks and secures the protector 1.
Prevents rattling. Here, the elastic force of the spring portion 2a as the elastic means 2 is appropriately set according to the weight of the wire harness protected by the protector, the locking force of the clip 6, and the like.

With such a structure, the protector can be prevented from rattling due to the vibration of the vehicle, and the generation of abnormal noise can be prevented. Also, as shown in the prior art,
Since the nut for preventing abnormal noise can be replaced with a separate clip, the protector can be securely fixed only by pushing the clip without tightening the nut, which deteriorates workability. It is possible to prevent an increase in man-hours.

The present invention can also be applied to the prior art shown in FIG. In this case, the elastic means 2 of the present invention is attached to the seat surface portion of the A protector 1 located on the vehicle panel 5 side.
By applying the above structure, the A protector 1 is pushed up with respect to the vehicle panel 5 and is fixed in close contact with the B protector 1'locked to the stud bolt 4 by the locking portion 6 '.

With such a structure, the clip can be replaced by an integrally molded clip without using a nut for preventing abnormal noise, so that an increase in cost due to an increase in the number of parts can be suppressed. In this embodiment, only the spring portion protruding toward the mounting surface side is described as the elastic means, but it goes without saying that the present invention is not limited to this. That is, a plurality of spring portions as shown in FIG. 1 may be provided around the mounting hole 3, or an elastic body may be provided concentrically with the mounting hole.

Further, in this embodiment, the elastic means is provided on the protector side, but in the present invention, the elastic means is provided so as to press the clip as the locking means in the direction of removing from the bolt (opposite mounting surface direction). The elastic means may be provided on the protector side surface of the separate clip.

[0015]

As described above, according to the first aspect of the invention, the protector is fixed without rattling due to the locking force of the clip locked to the stud bolt and the elastic force of the elastic means. Since the generation of abnormal noise due to the vibration of the vehicle can be prevented and the nut for preventing the abnormal noise can be replaced with a clip, it is possible to suppress an increase in cost due to an increase in the number of parts. Further, since the protector can be securely fixed only by the pushing operation of the clip without performing the nut tightening operation, it is possible to prevent the workability from being deteriorated and the number of steps to be increased.
