Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a protector in which a wire harness is housed in a U-shaped protector body in which a pair of side walls are integrally formed in the same direction from both sides of a bottom portion.

[0002]

[Prior Art]

 FIG. 4 shows the protector 1 in which the wire harness is accommodated. The protector 1 includes a protector body 3 in which a wire harness is housed, and a lid 5 that closes the upper portion of the protector body 3. The protector body 3 is formed in a substantially U-shape by integrally forming a pair of side walls 9a and 9b from both sides of the bottom portion 7 in the same direction. The lid 5 has a flat plate shape, both sides thereof are bent in the same direction, and a pair of lock arms 11 are integrally formed on both sides downward, and locking ridges 13 are projectingly provided on the respective lock arms 11. ing.

On the other hand, locking frames 15 are formed on the outer peripheries of the side walls 9a and 9b of the protector body 3, respectively. By inserting the lock arm 11 into the locking hole 17 surrounded by the locking frame 15 and the side walls 9a and 9b, and locking the upper end of the locking projection 13 to the lower end of the locking frame 15. The lid 5 is held by the protector body 3.

By the way, when the protector body 3 is injection-molded from a synthetic resin, the pair of side walls 9a and 9b fall inward due to contraction due to a decrease in temperature after molding, and the distance between the locking frames 15 becomes narrow. For this reason, the distance between the locking holes 17 becomes smaller than the distance between the pair of lock arms 11, and the work of inserting the lock arm 11 into the locking holes 17 is troublesome.

Therefore, Japanese Patent Laid-Open No. 6-72821 discloses a protector which prevents the side walls 9a and 9b from falling after being molded. In the protector shown in FIG. 5A, the thickness of the connecting portion between the bottom portion 7 and the side wall 9a is 1/2 of the thickness t of the bottom portion 7. In the protector shown in FIG. 5B, the thickness of the bottom portion 7 immediately before the side wall 9a is 1/2 of the thickness t of the bottom portion 7.

[0006]

[Problems to be solved by the device]

 However, even in the protector which prevents the side walls from collapsing in the above-mentioned conventional publication, it was not possible to reliably prevent the side walls 9a and 9b from collapsing inward after the molding, depending on the molding conditions. ..

Therefore, an object of the present invention is to provide a protector capable of reliably preventing the pair of side walls from collapsing.

[0008]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention is characterized in that a collapse preventing member for preventing collapse of both side walls inward is provided between the both side walls in a breakable manner.

[0009]

[Action]

 According to the present invention, the fall-prevention member is formed integrally with the protector main body, so that after the protector main body is formed, the fall-down prevention member supports the inward fall of both side walls and both side walls fall inward. Never. In addition, when installing the electric wire in the protector body, the fall-prevention member is ruptured from the protector body and easily detached from the protector body.

[0010]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows a protector 21 of this embodiment. Between the both side walls 9a, 9b of the protector body 3 of the protector 21, a flat plate-like collapse prevention member 23 is integrally formed with the protector body 3. The collapse prevention member 23 is formed to be slightly smaller than the inner shape of the protector body 3, and is connected to both side walls 9a and 9b of the protector body 3 and the bottom portion 7 at a plurality of breaking portions 25. The breakable portion 25 is formed to be thin so that it can be easily broken, and is formed integrally with the protector body 3 when the protector body 3 is molded to prevent the side walls 9a and 9b from falling inward. Further, the fall-down prevention member 25 is provided on both sides in the longitudinal direction of the protector body 3 and at an intermediate portion at a predetermined interval.

When accommodating a wire harness (not shown) in the protector body 3, the breaking portion 25 is broken so that the protector body 3 is detached from the protector body 3. In this case, even if the fall-prevention member 23 is detached from the protector body 3, since a certain amount of time has elapsed from the time of molding, the protector body 3 becomes cold and both side walls 9a and 9b do not fall inward. ..

After the collapse prevention member 23 is detached from the protector body 3, a wire harness (not shown) is housed in the protector body 3 and the lid 5 closes the upper opening. At this time, since the both side walls 9a and 9b are not tilted inward, the lock arm 11 of the lid 5 can be easily inserted into the locking hole 17 of the locking frame 15.

Next, another embodiment shown in FIGS. 2 and 3 will be described. In the protector 27 shown in FIG. 2, a rod-shaped collapse prevention member 29 is integrally formed on the upper portion between the side walls 9a and 9b of the protector body 3 with a thin connecting body 31 interposed therebetween. The thin connecting body 31 can be easily broken, and can be easily broken when the wire harness (not shown) is housed in the protector body 3, and the collapse prevention member 29 can be easily detached from the protector body 3. ..

Also in this embodiment, since the fall prevention member 29 is integrally formed when the protector main body 3 is formed, the both side walls 9a and 9b do not fall inward, and the lock arm 11 of the lid 5 is formed on both sides. It can be easily inserted into the locking frame 15 formed on the walls 9a and 9b.

Next, the protector 33 shown in FIG. 3 will be described. In the protector 33 shown in FIG. 3, the entire outer circumference of the collapse prevention member 35 is connected to both side walls 9a and 9b of the protector body 3 and the bottom portion 7 through a thin portion 37. The thin portion 37 can be easily broken, and can be easily broken when the wire harness (not shown) is housed in the protector body 3, and the collapse prevention member 35 can be detached from the protector body 3.

Also in this embodiment, since the fall prevention member 35 is integrally formed through the thin portion 37 when the protector main body 3 is formed, the side walls 9a and 9b do not fall inward and the lid is closed. The lock arm 11 of the body 5 can be easily inserted into the locking frame 15 formed on both side walls 9a and 9b.

[0018]

[Effect of the device]

 As described above, according to the protector of the present invention, since the collapse prevention member for preventing the collapse of both side walls inward is provided so as to be breakable between both side walls, the collapse after the pair of side walls is collapsed. It can be surely prevented.
