However, also in this case, the width d3 of the support recess 47 of the support member 45 is adjusted to the width d4 of the protector body 3.
Therefore, the support member 45 cannot be shared and the side walls 9a and 9b cannot be prevented from falling down.

On the other hand, the protector 35 shown in FIG. 8 is provided with a locking portion 53 for locking the distal end portion 51 of the support member 49 on the protector main body 3, and according to this, straightening of the side walls 9a, 9b is corrected. However, since it is impossible to prevent the protector body 3 from falling down during molding, the work of attaching the deformed protector body 3 to the support member 49 becomes complicated, and the support member 49 cannot be shared.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a protector support structure capable of securely supporting a protector body, using a common support member, and preventing the side walls from falling down.

[0016]

In order to achieve the above object, the present invention provides a supporter having a protector body having a pair of side walls erected in the same direction from both sides of a bottom provided on a flat work table. In the support structure of the protector body supported by the member, a thick portion is provided on a side wall of the protector body,
An insertion support portion is formed in the thick portion along the direction in which the side wall is erected, and the insertion support portion is inserted into the insertion hole portion of the support member to support the side wall. And a horizontal support portion which is provided orthogonal to the main body and supports the lower surface side of the protector body.

[0017]

When the insertion support portion of the support member is inserted into the insertion hole, the insertion support portion supports the side wall along the standing direction, and the horizontal support portion supports the lower surface side of the protector body. It is supported in a stable state by the member. In addition, by setting the shape of the insertion hole portion to the insertion support portion, the same support member can also support different protector bodies, so that the support member can be shared. Further, by providing a thick portion on the side wall, it is possible to prevent the side wall from falling into the inside.

[0018]

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

FIG. 1 is a perspective view of a protector according to the present embodiment.
FIG. 2 is a cross-sectional view of a main part of the protector of FIG.
Shows a state before being supported by the support member, and (b) shows a state where it is supported by the support member. The same parts as those in the related art are denoted by the same reference numerals, and description thereof will be omitted.

The protector 55 has a bent portion 57 that is bent at a substantially right angle, and is formed so that its planar shape is substantially L-shaped. Inside the bent portion 57 of the protector body 3, a thick portion 59 is provided integrally with the side wall 9 a so as to protrude toward the housing recess 10. The thick portion 59 is formed in a substantially cylindrical shape having an insertion hole 61 in the center.
It penetrates from the bottom 7 side toward the lid 5 side along the direction in which the side wall 9a is erected. The thick portion 59 protrudes from the lid 5 side, and the lid 5 is formed with a through hole 63 through which the protruding portion of the thick portion 59 penetrates.

The support member 65 is provided with an insertion support 67 extending substantially perpendicularly to the work table 29 and a horizontal support 69 extending substantially perpendicularly from the insertion support 67.
The insertion support portion 67 is a rod-shaped body penetrating the insertion hole 61 and is formed in a tapered shape such that the tip becomes thin.
When the insertion support 67 is inserted into the insertion hole 61, the insertion support 67 engages with the insertion hole 61 to support the side wall 9 a of the protector body 3. At this time, the side wall 9a is supported along the upright direction, so that the support state of the protector 55 is stabilized. In this embodiment, the horizontal support portion 69 assists the bottom portion 7 of the protector body 3 from the lower surface in an auxiliary manner, so that the support state is more reliable.

When the wire harness W is routed and housed in the protector main body 3, the support member 65 is disposed at a predetermined position on the work table 29, and the work is performed while the protector main body 3 is supported by the support member 65. At this time, since the side wall 9a of the protector main body 3 is supported in a stable state by the insertion support portion 67 and the bottom portion 7 is additionally supported by the horizontal support portion 69, a reliable support state is obtained. Therefore, there is no possibility that the support state of the protector main body 3 becomes unstable due to the weight of the wire harness W and the like, and the workability of arranging the wire harness W is improved.

The thick portion 5 formed on one side wall 9a
Since the protector main body 3 is supported by inserting the insertion support portion 67 into the insertion hole 61 of FIG.
If the inner diameters of the support members 65 are the same, it is possible to cope with protector bodies having different widths without changing the shape and size of the support member 65 according to the width of the protector body 3. Therefore, a plurality of types of protector main bodies 3 can be supported by the same support member 65, and the cost can be reduced by using a common support member 65.

Further, since the thick portion 59 prevents the side wall 9a from falling down, the lock arm 37 can be easily inserted into the locking hole 43, and the workability of mounting the lid 5 is improved. Further, thick portions 71 and 73 are provided on the other side wall 9b so as to be displaced from each other, and insertion holes 75 and 77 are formed in the thick portions 71 and 73 so that the protector body 3 is separated from both side walls 9a and 9b. Can also be supported. Thus, both side walls 9a, 9b
By supporting the protector body 3 from above, a more stable supporting state can be obtained. Further, since the thick portions 71, 73 are formed on both the side walls 9a, 9b, the thick portions 71, 73 can prevent the side walls 9a, 9b from falling down.

Further, since the thick portion 59 projects from the cover 5 inside the bent portion 57 of the protector body 3, the projecting portion of the thick portion 59 extends from the bent portion 57 of the protector body 3 to the wire harness W. Prevents sticking out. Thereby, as shown in FIG. 3, there is no possibility that the wire harness 79 will protrude from the housing recess 10 when the cover 5 is mounted, and the mounting operation of the cover 5 is easy and reliable.

By setting the cross-sectional shape of the insertion hole 61 and the insertion support portion 67 to a polygonal shape such as a rectangle, the protector body 3 can be prevented from rotating around the insertion support portion 67, and more reliable support can be achieved. The state is obtained.

In this embodiment, the thick portion 59 is provided so as to protrude toward the housing recess 10 of the bent portion 57 of the protector body 3, but to protrude outside the bent portion 57 as shown in FIGS. Thick portion 59 may be provided. According to such a protector 81, since the thick portion 59 is provided on the outer side of the bent portion 57, it does not become a hindrance when the wire harness W is accommodated in the accommodating recess 10 of the protector main body 3, and workability is improved. improves.

Although the insertion hole 61 is formed to penetrate the thick portion 59, the insertion hole 61 does not have to penetrate as long as it is formed deep along the direction in which the side walls 9a and 9b are erected.

The protector is not limited to the L-shape, but may be another shape such as a linear shape.

[0030]

As described above, according to the present invention, the protector body can be securely supported, the support member can be shared, and the workability can be improved and the cost can be reduced. In addition, it is possible to prevent the side wall from falling down, and the workability of attaching the lid is improved.
