Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a protector for accommodating and protecting electric wires and a method of accommodating electric wires in the protector.

[0002]

2. Description of the Related Art An example of a conventional protector of this type is shown in FIG. 5 (see Japanese Patent Laid-Open No. 26208/1990).

The protector 1 comprises a protector body 3 and a cover 5. The protector body 3 is formed in a substantially U-shaped groove, and has a bottom surface 7 and a pair of side walls 9 and 9 provided upright from both sides of the bottom surface 7. The bottom surface 7 and the side wall 9 form a storage recess 11 having a U-shaped cross section for storing the wire harness W (a wire assembly for an automobile). Cover 5
Is formed in a lid shape so as to cover the upper surface of the protector body 3. A flexible locking frame 13 is provided on the outer surface of the side wall 9 of the protector body 3, and the locking frame 1 is provided.
3 is a locking hole 13a that penetrates along the standing direction of the side wall 9.
Is equipped with. The side edge 5a of the cover 5 has a protrusion 15
A locking arm 15 that is a projecting a is provided. The upper surface of the protector body 3 is covered with the cover 5, and the locking arm 15
Is inserted into the locking hole 13a of the locking frame 13, the locking frame 13
The projection 15a is locked to the lower end of the cover 5, and the cover 5 is attached to the protector body 3.

A notch 17 having an opening 17a on the upper surface side of the protector body 3 is formed at a position where both side walls 9, 9 of the protector body 3 face each other along the standing direction of the side wall 9. A jig pin 19 for locking the upper surface of the wire harness W is inserted into the cutout portion 17. The jig pin 19 has an appropriate rigidity, and one end thereof is supported by a support base 23 provided on the wiring plate 21 so as to be slidable in a direction perpendicular to the protector body 3. The jig pin 19 inserted into the notch 17 and passed between the both side walls 9 and 9 locks the upper surface of the wire harness W housed in the housing recess 11 to prevent the wire harness W from rising. As a result, even when the wire harness W is stored in a large amount, the wire harness W is sandwiched between the protector body 3 and the cover 5 when the cover 5 is attached, and part of the wire harness W protrudes out of the protector 1. It can be prevented that the cover 5 is attached and the cover 5 can be easily attached.

[0005]

However, in such a structure of the protector 1, since the support base 21 for supporting the jig pin 19 is indispensable in the assembling work of the protector 1, the work is performed by the wiring board 21. However, there is a disadvantage in that even if the jig pin 19 is used, a sufficient effect cannot be expected when it is assembled in a place other than the wiring stand 21.

The present invention has been made in order to solve the above problems, and provides a structure of a protector capable of preventing the wire harness from being lifted up by a jig pin without limiting the place for assembling the protector. With the goal.

[0007]

The invention according to claim 1 is
A structure of a protector body which is formed in a substantially U-shaped groove and has a protector body for accommodating and protecting an electric wire therein, and a cover for covering the upper surface of the protector body. Forming a cutout portion having an opening on the upper surface side of the protector body, into which a jig pin that locks the upper surface of the electric wire is inserted, and from the opening of the jig pin to the cutout portion in the protector body Is provided, and a flexible lock portion that locks the inserted jig pin to prevent the jig pin from coming off from the opening is provided.

According to a second aspect of the present invention, an electric wire is housed inside a protector body formed in a substantially U-shaped groove, and the electric wire is formed at a position where both side walls of the protector body face each other. A jig pin that locks the upper surface of the electric wire is inserted into a notch portion having an opening in the protector body, and the jig pin is allowed to be inserted into the notch portion from the opening. After the jig pin is locked to the flexible lock portion that prevents the jig pin from coming off from the opening, and the upper surface of the protector body is covered with the cover while the jig pin is locked. The jig pin is pulled out from the cutout portion.

A third aspect of the present invention is the protector according to the first aspect, characterized in that a cover-side cutout portion is formed in the cover so as to face the cutout portion of the protector body.

The invention according to claim 4 is the protector according to claim 1 or 3, wherein at least one of the flexible lock portion and the jig pin is provided integrally with the protector body. It is characterized by

[0011]

According to the structure of the protector described in claim 1 and the method for accommodating the electric wire in the protector according to claim 2, when the protector is assembled to the electric wire, the electric wire is first accommodated inside the protector body, and the notch is provided with a jig. Insert the pin, lock the jig pin to the flexible lock part, cover the upper surface of the protector body with the cover, and then pull out the jig pin from the notch. Therefore, when installing the cover, the upper surface of the wire is always locked by the jig pin, so that the wire is prevented from rising and the wire is not caught between the protector body and the cover when the cover is attached. The work of attaching the cover can be easily performed.

Further, since the protector body is provided with the flexible lock portion so that the jig pin is locked to the flexible lock portion, the protector assembling work is performed at any place other than the wiring board or the like. Even if the above is performed, the jig pin can effectively prevent the electric wire from floating.

In the structure of the protector according to the third aspect, since the cover side cutout is formed in the cover so as to face the cutout in the protector body, the locking position of the jig pin by the flexible lock portion is set in the protector body. It can be provided close to the top surface. Therefore, even when the electric wire is stored by making maximum use of the capacity in the protector body, the jig pin can be locked to the flexible lock portion, and the space efficiency can be improved.

In the structure of the protector according to claim 4, when the flexible lock portion is provided on the protector main body, the protector main body can have a simple structure, and the protector main body can be manufactured at low cost. . Further, when the jig pin is provided integrally with the protector body, the jig pin parts need not be managed and the workability when assembling the protector is improved.
