DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protector for protecting a wire such as an electric wire, a wire harness and an optical fiber cable.

[0002]

2. Description of the Related Art As this type of protector, FIGS.
The following are known. This protector 10 '
A substantially plate-shaped protector body made of synthetic resin having a routing path K for routing the wire harness W in a substantially U-shape and having U-shaped locking frames 12 and 12 ′ integrally protruding on both outer sides, respectively. 11 and one end of the protector body 11 is openably and closably supported via a flexible hinge 20, and covers the routing path K when closed to form a substantially U-shaped wire harness W between the protector body 11. And a cover 21 made of a synthetic resin for accommodating and protecting a portion bent in a substantially U-shaped plane.

At substantially the center of the back surface 11b of the protector body 11, a clamp portion 16 for detachably attaching the protector body 11 to a circular mounting hole 31 of a vehicle body 30 is integrally formed. The clamp portion 16 has a pair of flexible locking claws 16a, 16a, and each tip of the pair of locking claws 16a, 16a is attached to the mounting hole 3 of the vehicle body 30.
It is locked to and detached from the edge of one hole. That is, a pair of legs 17, 17 'integrally formed on both ends of the back surface 11b of the protector body 11 and the pair of locking claws 16a,
The protector body 11 is attached to the vehicle body 30 such that the vehicle body 30 is sandwiched between the respective ends of the protector body 16a. When the clamp portion 16 is formed, a pair of forming holes 18, 18 are formed in the protector body 1.
1 is formed so as to penetrate from the front surface 11a to the back surface 11b.

As shown in FIGS. 5 (a), 5 (b) and 6, the cover 21 has a pair of parallel portions 22, 22 'having an inverted U-shaped cross section which face each other so as to be substantially parallel to each other. A pair of parallel portions 22, 22 'are integrally formed in a substantially U-shaped plane with a connecting portion 23 having an inverted U-shaped cross section connected to each base end of the pair. Outside the one parallel portion 22, a triangular prism-shaped locking projection 24 that is locked to one locking frame 12 of the protector body 11 when the cover 21 is closed is integrally formed.
On the outside of the other parallel portion 22 ', a triangular prism-shaped locking projection 24' which is locked to the other locking frame 12 'of the protector body 11 when the cover 21 is closed is integrally formed.

[0005] Then, as shown in FIGS. 4 and 6, the cover 21 is closed to the protector body 11 via a flexible hinge 20 and the wiring path K of the protector body 11 is covered with the cover 21. Thereby, a portion of the wire harness W that is bent into a substantially U-shape between the protector body 11 and the cover 21 is housed and protected.

[0006] A similar technique relating to the protector 10 'is disclosed in Japanese Utility Model Laid-Open Publication No. 64-37315.

[0007]

However, in the conventional protector 10 ', when the wiring path K of the protector body 11 is closed and covered with the cover 21, the pair of parallel portions 22, 22' of the cover 21 are held with both hands. And the locking projections 24, 24 'on both sides of the cover 21 must be operated so as to be locked to the locking frames 12, 12' on both sides of the protector body 11, respectively. The fitting work became complicated and required skill.

The cover 21 is formed of a pair of parallel portions 22 and 2
2 'and the connecting portion 23 form a substantially U-shaped plane, so that a space is created in the center of the inside.
When the cover 21 is attached to the cover 21, the pair of forming holes 18, 18 of the protector body 11 are
It is difficult to press the clamp portion 16 against the mounting hole 31 side of the vehicle body 30 by the exposed pair of forming holes 18, 18 being exposed from between the 2 ′ and the connecting portion 23.

Therefore, the present invention has been made to solve the above-mentioned problems, and can improve the workability of fitting the cover to the protector body and the workability of mounting the protector body to the mounted body. The purpose is to provide a protector.

[0010]

An object of the present invention is to provide a protector body having a routing path for routing a striatum in a substantially U-shape and having locking portions on at least both sides, respectively.
A substantially U-shaped cover for covering the wiring route of the protector body when closed and accommodating and protecting the striatum between the protector body and a cover for closing the protector body when the cover is closed. In a protector in which a locking portion of the cover is freely locked to a stop portion, a pair of parallel portions facing each other so that the cover is substantially parallel, and a connection respectively connected to respective base ends of the pair of parallel portions. And a pressing operation portion for pressing the cover against the front side of the protector body between the pair of parallel portions and the connecting portion. I do.

In this protector, the cover is pressed between the pair of parallel portions forming a substantially U-shape of the cover and the connecting portion toward the front side of the protector body having a substantially U-shaped wiring path. Since the operating section is provided, the pressing operation section facilitates the work of fitting the cover to the protector body when closing the wiring path of the protector body with the cover.

According to a second aspect of the present invention, there is provided the protector according to the first aspect, wherein each of the locking portions is provided on each of the outer sides of the pair of parallel portions and on both sides of the protector body opposed to each of the outer portions. The pressing operation portion is provided at a substantially intermediate position between the pair of locking portions on the cover side.

In this protector, since the pressing operation portion is provided at a substantially intermediate position between the pair of locking portions on the cover side, the pressing operation portion is merely pressed against the front surface side of the protector main body so that the pressing operation portion is provided on the protector main body side. The pair of locking portions on the cover side are extremely easily and reliably locked to the pair of locking portions.

According to a third aspect of the present invention, there is provided the protector according to the first aspect, wherein a clamp portion for detachably attaching the protector body to a mounting hole of the mounted body is formed integrally on the back surface of the protector body. Pressing the pressing operation portion between the pair of parallel portions and the connecting portion so as to cover a forming hole formed in the protector body and contact the surface of the protector body when forming the clamp portion. , And are formed integrally with each other at a position opposed to.

In this protector, the pressing operation portion is connected to the pair of parallel portions of the cover so as to cover a forming hole formed when the clamp portion is formed on the back surface of the protector body and to contact the surface of the protector body. Since it is integrally formed at a position opposite to the clamp portion between the clamp portion and the pressing portion, the pressing operation portion covers the forming hole, so that the clamp portion is easily pressed, and the cover is closed to accommodate the striated body. The workability of mounting the protected protector body to the mounted body is further improved.
