Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body mounting structure for a wire harness for an automobile, and more particularly, to a wire in which a locking portion of a clamp mounted on a wire harness is inserted and locked into a locking hole provided on a body side. When the harness is attached to the body, the clamp can be easily removed from the body.

[0002]

2. Description of the Related Art A band-type or board-type clamp is attached in advance to a wire harness routed along a body of an automobile, and a wing-like engaging portion of the clamp is formed in the body. The wire harness is fixed to the body by pushing it into the locking hole.

In recent years, the necessity of separate disposal and recycling of automobile parts and materials has been increasing. As for the above-mentioned clamp, not only can the wire harness be securely fixed to the body, but also if necessary, it can be easily removed from the body. There is a need to be able to remove and recycle.

However, in the above-described general clamp, in order to remove the clamp from the body, it is necessary to release the lock by bending the locking portion inward with a finger to get out of the locking hole. Actually, however, it is difficult for the wire harness to hinder the bending of the locking portion of the clamp, and once the clamp is attached to the body, it cannot be removed.

Japanese Patent Laid-Open Publication No. Hei 8-200327 discloses a structure in which a clamp can be removed from a body.
(A) The mounting structure shown in (B) has been proposed. In this structure, an inverted L-shaped support member 2 protrudes from the mounting surface of the body 1 and locking grooves 3 are recessed on both sides thereof.
A clamp 4 having a pair of locking portions 4a and an upwardly curved bottom 4b is provided, the bottom 4b of the clamp 4 is locked by the support member 2, and the lower ends of the pair of locking portions 4a are locked by the locking grooves 3.
And the clamp 4 is attached to the body 1. The wire 5 is inserted into the clamp 4 by pushing and expanding the locking portion 4a from above, and after the insertion, the locking portion 4a is elastically restored to hold the wire 5.

When the clamp 4 having the above structure is used, when the wire 5 is pulled upward with a strong force, the locking portion 4a is pushed out by the wire 5, and the wire 5 can be removed from the body.

[0007]

However, in the above-mentioned mounting structure, it is necessary to provide the locking groove 3 on the mounting surface of the body 1, so that complicated processing such as cutting the body 1 is required. Further, since the wire 5 comes into direct contact with the support member 2,
There is a risk of disconnection, and in order to prevent the disconnection, an exterior is required, which leads to an increase in cost and labor.

Further, when attaching the wire to the body,
First, a step of attaching the clamp 4 to the body 1 is required, and the number of attaching steps increases, which is a factor of impeding productivity. Further, when the wire is removed, the clamp 4 remains on the body 1 side, and furthermore, it is necessary to remove the clamp 4 from the body 1. Furthermore, the diameter of the wire (or wire harness) is various, and if the diameter is large, there is a problem that the wire does not enter between the locking portions 4a of the clamp 4, and if the diameter is small, it cannot be fixed. In order to solve this problem, various types of clamps are required according to the diameter, and there is a problem that the number of parts increases.

The present invention has been made in view of the above-mentioned problems, and a clamp for fixing a wire harness to a body is provided.
It is an object of the present invention to be able to easily remove a body together with a wire harness.

[0010]
