DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wire harness clamp for fixing a wire harness routed to an automobile to a vehicle body, and more particularly to a clamp for a vehicle body panel in which a mounting hole provided is a round hole or a long hole. It can be locked.

[0002]

2. Description of the Related Art A wire harness for an automobile needs to be fixed to a vehicle body panel in order to route the wire harness along a required route. For this reason, the wire harness is attached to the wire harness and connected to a mounting hole provided in the vehicle body panel. Clamps are provided with blades to stop.

A mounting hole provided in the vehicle body panel P has a round hole H as shown in FIG.
1 (for example, φ7 mm) and an elongated hole H2 (for example, φ7 × 12 mm) as shown in FIG. 7B. A clamp 1 having an engaging portion 1a corresponding to the diameter of the round hole H1 shown in FIG. 10A is used for attachment to the round hole H1, and FIG. The clamp 1 'having the engaging portion 1a' corresponding to the hole size of the elongated hole H2 shown in FIG.

Has a holding hole 9a 'corresponding to the clamp 1', so that the clamp jigs 9 and 9 'are dedicated jigs respectively.

Therefore, as a clamp that can be shared by one clamp for these two types of clamp mounting holes, there is known a clamp for a wire harness described in Japanese Patent Application Laid-Open No. Hei 8-82389 shown in FIG. This clamp 1 "has two blade portions 1c, a first blade portion 1d" for locking to a small-diameter round hole and a second blade portion 1c "for locking to a large-diameter long hole. "1d" are provided orthogonally.

[0006]

However, since the above-mentioned clamp requires two blades corresponding to the round hole and the long hole, the structure becomes complicated and the molding becomes difficult. Since the members protrude in a positional relationship perpendicular to each other, there is a problem that the members are easily caught with other members.

SUMMARY OF THE INVENTION The present invention has been made in consideration of the above problems, and provides a clamp that can be commonly used and locked by a simple structure including a single blade even if a mounting hole provided in a vehicle body panel is a round hole or a long hole. Is an issue.

[0008]

In order to solve the above-mentioned problems, the present invention is characterized in that the present invention is applied to a wire harness, which is commonly used for two types of mounting holes, namely, a round hole and a long hole of a vehicle body panel. A clamp for a wire harness that can be inserted and locked, wherein a pair of blades are formed by folding back a pair of blades from the tip of a shaft protruding from a mounting portion to the wire harness, and a locking step is formed on each of the blades. A coaxial with the base of the shaft portion, an elongated hole engagement portion that can be fitted and fitted to the elongated hole,
A round hole engaging portion that is arranged above the elongated hole engaging portion and that can be fitted and fitted to the round hole is protruded, and the elongated hole engaging portion and the round hole engaging portion are provided. At the outer peripheral portion, a blade escape portion that can receive the blade portion when the blade portion bends in the axial direction is formed in a cutout shape, and when the insertion into the round hole is locked, the engagement with the round hole is performed. And the engaging step is engaged with the inner peripheral edge of the round hole. On the other hand, at the time of insertion into the elongated hole, the engaging portion for the elongated hole is inserted into the elongated hole. Along with
A clamp for a wire harness is provided, wherein a lower end of the blade is locked to an inner surface of a vehicle body panel.

[0009] With the above configuration, at the time of locking to the round hole,
The engagement portion for the round hole is fitted and positioned in the inner periphery of the round hole, and the locking step of the blade portion is bent so that the tip of the locking step portion enters the blade escape portion, and the locking step portion is round. By being elastically locked to the inner peripheral edge of the hole, the hole can be fixed stably without rattling. On the other hand, at the time of engagement with the elongated hole, the elongated hole is inserted further into the inner periphery of the elongated hole, and at the same time, the wing portion is completely inserted into the elongated hole. As a result, both ends elastically return in the opening direction, and the inner surface of the vehicle body panel is locked at the lower end of the locking step, so that it can be similarly stably fixed.

Furthermore, since one blade can be shared for two types of mounting holes, a round hole and a long hole, the structure of the clamp can be simplified. In addition, a clamp jig used for attaching the clamp to the wire harness can be used in common because it has a holding hole for a long hole.
