Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wire harness protector for vehicles, particularly automobiles.

Some vehicles, especially passenger cars, have a fuel tank installed under the floor at the rear of the vehicle, and the wire harness connected to the electric oil level gauge of this fuel tank is wired to the floor through the floor through-hole for the connector. , conventionally, as shown in Figure 1,
A floor through hole (also called a service hole) of the attachment part B recessed in the rear floor A.

)C connection plug (also called twer sender plug).

)D was connected to wire harness W, but at this time,
Connect the end of the wire harness W leading to the grommet fitting hole F of the cover board E made of metal material to the connection plug D,
Next, the wire harness W was inserted into the groove K in the floor surface, attached to the lower back L at the rear as shown in FIG. 2, and then covered with the protector sheet G.

As is clear from the above, the number of component parts is large, and assembling the wire harness for waterproofing and protection requires a considerably complicated procedure, and also necessitates the work of fitting a grommet with a disc for ease of work. There were some drawbacks.

SUMMARY OF THE INVENTION An object of the present invention is to provide a wire harness protector that can open and close a cover piece that holds a wire harness in order to eliminate the above-mentioned drawbacks.

Hereinafter, one embodiment of the present invention will be explained according to FIGS. 3 to 8. In the figure, 1 is a floor in the rear trunk of an automobile, and the floor 2 is used to attach a wire harness protector WP. In this example, a fuel tank (not shown) is provided.

) is located at the top. Reference numeral 4 denotes a floor through hole provided through the attachment portion 2, and includes an underfloor fuel tank (not shown).

) is exposed.

6 is a connection plug of the electric oil level gauge 5, and is a connector (not shown) connected to the end of the wire harness W.

). WP indicates the entire wire harness protector (hereinafter simply referred to as protector),
In this example, it is molded from a synthetic resin material.

Next, each part of the protector WP described above will be described in detail. In the figure, γ is a cover plate whose central part is formed into an almost inverted dish shape, and the flange 8 on the outer periphery has screw holes 9 for fastening. A plurality of (three in this example) etc. are installed through the hole.

Reference numeral 10 denotes a cover piece which is bendably connected to the top surface 11 of the cover board 1 at a bending part 13, and whose planar shape is formed into a substantially U-shape, and for guiding the wire harness W. The guide groove portion 12 has a substantially trapezoidal cross section.

However, in this example, the above-mentioned bent portions 13 are connected in a thin manner, and the length of the wire harness is different when the cover piece 10 is upright and when the cover piece 10 is fitted to the cover plate γ. so that they are almost the same, that is, the eighth
In order to make the illustrations 11 and 12 substantially the same, the cover piece 10 is approximately 45 mm in length with respect to the longitudinal direction of the cover plate γ.
It is molded in a diagonal shape.

Reference numeral 14 denotes a connecting part which is hung in an annular shape near the base end 15 on the lower surface of the cover piece 10, and a part of the connecting part has a notch-shaped first through groove 16 opened in the longitudinal direction of the cover piece 10. It is removably fitted into a connecting hole 171 formed through the top surface 11 of the cover plate γ.

Therefore, the connecting portion 14 and the connecting hole 1γ are formed to have relative dimensions that allow watertightness to be maintained during fitting.

Reference numeral 18 denotes a second through groove recessed in the edge ζ of the connecting hole 1γ, through which the wire harness W is guided.

Reference numeral 19 denotes a second support member for the wire harness W, which is disposed in the connecting portion 15 and opposite to the through groove 16, and supports the wire harness W.

Reference numeral 20 denotes a first support member of the wire harness W, and is provided near the center of the lower surface of the guide groove portion 12.

21-2.1 are flanges 22.1 of the cover piece 10, respectively.
The cover piece 10 is attached to the rear floor 1 with screws 23 through screw holes 22 .

Reference numeral 24 denotes a guide groove section provided diagonally in an upright manner at the outer end of the cover piece 10, and an entrance section 25 for the wire harness W is formed at a right angle in the upper part of the guide groove section. It has a cylindrical shape that can be opened and closed to hold the wire harness W.

However, the closing is performed by engagement between the hook protrusion 27a and the hook hole 27b.

Next, the functions and effects of the embodiment configured as described above will be specifically explained.

First, the case where the wire harness W is attached will be explained. In this case, the connection plug 6 is connected to a connection connector (not shown).

) and then attach the cover plate γ to the attachment part 3 of the rear floor 1.
When the screws are attached, the floor surface through hole 4 is covered with this cover plate γ.

Next, after raising and opening the cover piece 10, the cover piece 1
0], the second support member 19
．． 20 and lead out the wire harness W to the outside along the guide groove portion 12. Next, when the cover piece 10 is closed toward the cover panel 1 side, the wire harness W is wired on the floor surface, so this cover piece 10
are attached to the rear floor 1 with screws 23, and the assembly of the wire harness protector WP is completed.

In addition, when inspecting or repairing the wire harness W, it is convenient because the cover piece 10 can be opened with the wire harness W attached in the reverse order as described above.

In other words, the present invention has the feature that the cover panel and the cover piece are always integrated, so they are not lost, and not only is it easy to assemble the attachment part, but also the wire harness can be easily attached by closing the cover piece toward the cover panel. Unlike conventional methods, (a) there is no need for difficult grommet fitting work or protector sheet pasting work, which greatly reduces assembly man-hours; In addition, unlike conventional wiring systems that allow a greater degree of freedom in wiring, the length of the wire harness can be set to a predetermined length in advance, so extending the wire harness to the rear floor and assembling the cover piece can be done easily. It is simple, and effects such as effective waterproofing and dustproofing for the electric oil level gauge side can be obtained.

In addition, when the wire harness guide groove is obliquely provided at the end of the cover piece, a part of the wire harness is not bent sharply, so that the effect of protecting the wiring can be recognized.

Therefore, the present invention is a preferable invention as a wire harness protector, and has a large contribution to vehicle equipment.

Note that the bending portions 13 of the cover board 1 and the cover piece 10 may be connected by a hinge instead of the one shown.
