Description

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 locking and fixing structure for a protector for accommodating a linear body such as a wire harness and adjusting the arrangement 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) for disposing and protecting a wire harness to be mounted in a vehicle is required to have a structure that suppresses 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 8. As shown in FIG. 3, after the electric wire bundle 7 is accommodated in a predetermined disposition posture and inserted into the protector body 1 for protection, the protector cover 2 provided in the protector body 1 with a hinge structure is closed. Next, the stay 6 protruding from the surface of the vehicle panel 8 or attached to the surface of the vehicle panel 8 is inserted into the locking fixing portion 3 of the protector main body 1 and locked and fixed. Here, as the mounting stay 6, a commercially available product or an off-the-shelf product is often used, and it is impossible for the user to change the design, specifications and the like. In the following, the mounting means such as stays handled in the specification is limited to products whose design cannot be changed by the user.

Next, an example of the locking structure between the locking fixing portion 3 and the stay 6 of the vehicle body panel 8 described above is shown in FIG. 4 (a).
As described above, for example, a groove-shaped guide portion 4 for inserting and guiding the stay 6 is provided in the locking and fixing portion 3 provided at a predetermined position of the protector body 1, and the stay 6 is inserted to the end. Then, the locking projection 3'of the locking fixing portion 3 and the locking hole 6'of the stay 6 are engaged and locked.

[0005]

In such a conventional locking and fixing structure, the state in which the stay 6 is locked and fixed to the locking and fixing portion 3 is as shown in FIG. 4 (b). Although the locking projection 3 ′ of the fixing portion 3 is engaged with the locking hole 6 ′ of the stay 6, the guide portion 4 and the locking projection 3 ′ of the locking fixing portion 3 are provided.
Is molded in accordance with the width dimension of the stay 6 and the locking hole 6 ′ in consideration of the molding dimension error in advance.
Therefore, gaps A and B are formed in the width direction of the guide portion 4 (the left-right direction in FIG. 4B). This clearance A provides an appropriate guide clearance during the work of attaching the protector for inserting the stay 6 into the guide portion 4 and facilitates the work, but after locking and fixing to the stay 6, that is, after attaching to the vehicle body panel. Also has gaps A and B, there is a problem that rattling occurs in the width direction of the guide portion and abnormal noise is generated due to vibration when the vehicle is traveling.

In order to solve such a problem, when the width of the guide portion 4 is formed so as to match the width of the stay 6, the width of the guide portion becomes a predetermined dimension or less due to a molding dimension error, and thus the stay 6 is formed. It may be difficult to insert. An object of the present invention is to solve the above problems and provide a protector having a structure in which generation of abnormal noise is suppressed in locking and fixing the protector to a mounting surface.

In particular, in the invention of claim 1, the stay (mounting means) is inserted into the guide portion and is made of a material having elasticity larger than that of the protector body so as to extend along the insertion path of the stay. By forming the convex portion (pressing means), it is possible to prevent the occurrence of a gap between the locking fixing portion and the stay,
The purpose is to suppress the generation of abnormal noise due to vibration when the vehicle is running.

[0008]

In order to achieve the above-mentioned object, the invention according to claim 1 is a protector for accommodating a linear body and locking and fixing to a mounting means projecting from a predetermined mounting surface. A locking means having a guide part for inserting and guiding the attachment means, and a pressing means provided along the shape of the guide part and made of a material having elasticity greater than that of the protector. Is characterized by.

With such a construction, when the protector is locked and fixed, the locking position of the mounting means inserted into the guide portion of the locking and fixing portion provided on the protector is corrected by the pressing means, so that the guide portion A gap between the mounting means and the mounting means is prevented, and rattling of the mounting means in the guide portion is prevented.

The stay 6 is pressed toward the locking projection 3 ′ by the convex portion 5, so that the engagement between the locking projection and the locking hole becomes deep. Therefore, the gaps A and B are formed in the width direction (left and right direction) of the guide portion 4 and the locking hole 6 ′, but since the stay 6 is pressed and fixed by the convex portion 5,
Rattling is suppressed.

In the above embodiment, the convex portion 5 is shaped to extend along the guide portion 4 in accordance with the insertion path of the stay 6, but the present invention is not limited to this. It is sufficient that the convex portion 5 is formed so as to suppress or eliminate rattling in the locking and fixing state of the stop fixing portion and the stay 6. Further, in the case where the convex portion 5 is formed to extend, on the side where the stay 6 is inserted, a slope is formed in the inserting direction of the convex portion to widen the insertion opening, so that the insertion work (protector mounting) can be performed. Work) can be performed smoothly.

Further, if the structure of the first and second embodiments described above is combined and the stay 6 is pressed and fixed from the left, right, up and down directions, the rattling of the protector is completely eliminated and abnormal noise is generated. Is prevented from occurring. Further, the structure of the present invention, that is, the protector having different elastic materials can be integrally molded by a well-known two-color molding technique.
