Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a protector fixing structure with improved workability in mounting.

(Prior Art) In order to wire electric wires in a vehicle body of an automobile or the like, it is necessary to arrange a wire harness in which a large number of electric wires are bundled along each part.

Since this wire harness is branched and wired to the connector of each electric component, it is housed in a gutter-shaped protector at various places, and the protector is fixed to the panel of the vehicle body to make the wire harness compact and to prevent vibration. Protects against abrasion and cutting.

The structure which attaches the conventional protector to the panel of the body is the 4th.
It is as shown in FIG. 5 and FIG.

FIG. 4 is an overall perspective view of the protector, and FIG. 5 is a perspective view of the panel.

The main body 2 of the protector 1 is formed in a U-shaped cross section, and the wire harness 3 is housed therein.

The body 2 of the protector 1 has a clamp mounting piece 4,
4'are provided, and clamps 5, 5'are projected from the clamp mounting pieces 4, 4 '.

On the other hand, the panel 6 shown in FIG. 5 is provided with circular clamp holes 7, 7'corresponding to the positions of the clamps 5, 5'shown in FIG. The diameter of the clamp holes 7, 7'is slightly smaller than the heads of the clamps 5, 5 '.

To fix the protector 1 to the panel 6, the clamp 5,
By inserting 5'into the clamp holes 7, 7'of the panel 6, the elastic pieces formed on the head of the clamp are irreversibly fixed by utilizing the bending deformation and the restoring force.

(Problems to be Solved by the Invention) Although the conventional fixing structure of the protector is as described above, this structure has the following drawbacks.

The clamp 5 of the protector 1 has an adjacent clamp 5 '.
And the clamp pitch t is constant, while the clamp holes 7, 7'of the panel 6 are also constant pitch T.
However, the protector 1 and the panel 6 are usually manufactured at completely different places.

That is, since the panel is usually a part of the vehicle body, it is produced in a vehicle body manufacturing factory of the automobile, and the protector is produced in another factory as a fixed part of the wire harness.

Therefore, the variation in the clamp pitch t of the protector 1 and the variation in the clamp hole pitch T of the panel are large, and when these are combined, fitting and fixing may be difficult. Particularly, when the protector 1 is manufactured by injection molding of plastic, there is molding shrinkage of the plastic, which is likely to be different from the variation in the hole pitch T of the panel 6.

If these pitch variations occur, it becomes difficult to fix the protector, and the work efficiency drops rapidly.

Therefore, it has been a problem in this industry to reduce the pitch variation due to this processing.

[Constitution of device]

(Means for Solving the Problems) In order to solve the above problems, a protector fixing structure according to the present invention is a protector in which at least a pair of clamps having at least one elastic piece are protrudingly fixed at intervals. In a structure that comprises a panel having at least a pair of clamp holes that match the positions of the clamps, and the clamps are fitted and fixed in the clamp holes, the clamp holes are elongated holes that are long in the clamp hole pitch direction, and It is characterized in that the bending direction of the elastic piece is set in the minor axis direction of the clamp hole.

(Operation) The clamp hole in the present invention is a long hole that is long in the clamp hole pitch direction. Therefore, even if there is some variation in the pitch of the clamps or the clamp holes, the elongated holes that are long in the pitch direction act to absorb them.

On the other hand, the bending direction of the elastic piece of the clamp coincides with the minor axis direction of the clamp hole (long hole). That is, by bending the long hole in the short axis direction, even if the bending width is small, the locking is ensured.

Further, the ratio of the major axis / minor axis of the clamp hole is preferably about 1.5.

(Example) Hereinafter, the present invention will be specifically described with reference to the drawings. Fig. 1 ~
FIG. 3 shows an embodiment of the present invention, FIG. 1 is an overall perspective view of a protector, FIG. 2 is a sectional view taken along line AA of FIG. 1, and FIG. 3 is a perspective view of a panel.

In this embodiment, the main body 2 and the clamp mounting pieces 4 and 4'of the protector 1 are the same as the conventional ones. The clamps 5 and 5'include arrow-shaped elastic pieces 9 and 9'at the tip of the central shaft 8.
A pair of elastic pieces 9 and 9'are formed so as to bend in the arrow B direction, and the direction of the arrow B is a direction intersecting the pitch direction of the clamps 5 and 5'at a right angle.
Further, in the figure, 9a and 9a 'are locking portions formed at the tips of the elastic pieces 9 and 9'.

It is also possible to omit the elastic piece 9'on one side and lock the elastic piece 9 alone.

On the other hand, the panel 6 is provided with clamp holes 7, 7'at a constant pitch T.
In the present invention, the shape of the holes is a long hole and the long diameter is the pitch direction of each hole.

Next, an operation of fixing the protector 1 to the panel 6 will be described.

First, the wire harness 3 is housed in the protector 1, and the clamps 5 and 5'are inserted into the clamp holes 7 and 7'of the panel 6. At this time, even if there is some variation in the clamps 5, 5 ', the pitch t, and the pitch T of the panel holes 7, 7', since the clamp holes 7, 7'are long holes that are long in the pitch direction, this variation occurs. It is absorbed and the clamps 5, 5'can be easily inserted into the clamp holes 7, 7 '. When the clamps 5 and 5'are inserted, the elastic pieces 9 and 9'will become clamp holes 7,
Bending in the direction of the short axis of 7'and pushing it further, elastic pieces 9, 9 '
It is locked at the locking portions 9a, 9a '. Elastic piece 9,
Since the bending direction of 9'is the minor axis direction of the clamp holes 7, 7 ', the locking is reliable.

[Advantages of the Invention] Since the present invention has the above-described configuration, it has the following effects.

(1) Since the clamp holes are long holes that are long in the pitch direction, even if there are variations in the pitch of each clamp and the pitch of the clamp holes, this variation can be absorbed and the fitting work efficiency can be improved.

(2) Since the bending direction of the elastic piece of the clamp is the minor axis direction of the clamp hole, the locking fitting is reliable.
