Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a grommet for an automobile.

(Prior art) Conventionally, harnesses and
Pipes, cables, etc. (hereinafter simply referred to as "harnesses, etc.")
Grommets with insertion holes that match the size of each individual harness, etc., are used to pass the harness through. When pulling multiple harnesses, etc. through the through-holes of the panel, prepare multiple grommets that match the diameter of the harnesses, etc. to be pulled through, and fit one grommet to each harness, etc. It was attached to a through hole in the panel.

(Problem to be solved by the invention) The number and type of grommets to be used are determined in advance depending on the type of vehicle. However, in the past, it was troublesome to select the grommet to be used one by one and attach it to the panel, and if the wrong grommet was selected, problems could occur. .

(Means for Solving the Problems) The present invention provides a method for connecting one flange of a pair of flanges formed at a fitting portion that fits into a plurality of through holes provided close to each other in a panel. are connected by a flexible connecting part.

(Function) When first pulling one harness, etc. through the through-hole of a panel, once the grommet through which this harness, etc. is inserted is attached to the panel, the grommet through which the other harness, etc. should be inserted, pulls the first harness, etc. At the same time as passing it through, it is connected to the grommet mentioned above.

(Example) Hereinafter, the present invention will be explained in detail based on the illustrated example. As shown in Fig. 1, the cab floor panel 1 of a cab-over type automobile has various harnesses, cables such as a speedometer cable, and pipes such as cooler piping (hereinafter simply referred to as "harnesses, etc.") 2. Through-holes 10a, 10b, and 10c are drilled for pulling through, respectively, and the coupled grommet 3 is fitted into these through-holes 10a, 10b, and 10c. This coupled grommet 3 consists of three grommet parts 3a, 3b, 3c and two connecting parts 35a, 35b that connect the adjacent grommet parts 3a, 3b, 3c to each other, and is made of natural rubber or flexible material. It is formed by integrally molding a synthetic resin having a Each grommet part 3
a, 3b, 3c are three insertion holes 31a, 31b, 31c through which the harness etc. 2 is inserted, and each through hole 1.
0a, 10b, 10c, and flanges 33a, 3 formed at both ends of the fitting portions to form a pair.
It consists of 4a, 33b, 34b, 33c, and 34c. The connecting portions 35a, 35b connect through holes 10a, 10 of adjacent grommet portions 3a, 3b, 3c.
Flange 33 that is not pushed into b, 10c
a, 33b, and 33c are connected to each other. The inner diameter of each insertion hole 31a, 31b, 31c of the coupled grommet 3 is formed according to the outer diameter of the harness etc. 2 to be inserted, and has a different diameter. Flanges 33a, 33b, 33c, 34a, 34b, 34
flanges 34a, 34b, 34c that are pushed into the through holes 10a, 10b, 10c and protrude from the back surface of the cab floor panel 1;
It consists of flanges 33a, 33b, 33c that are not pushed into 0a, 10b, 10c.

As clearly shown in FIG. 2, the fitting portion 32a is fitted with the flange 34a pushed into the through hole 10a. Similarly, the fitting portion 32b is connected to the through hole 10b.
In addition, the fitting portions 32c are fitted into the through holes 10c, respectively. The connecting portion 35a is the same as the flange 33a.
b, and the connecting portion 35b is the same as the flange 33b and 33c.
and are connected to each other, and each connecting portion 3
The thickness of flanges 33a, 33
It is formed thinner than the thicknesses of b and 33c so that it can be easily bent. Also, the first
As shown in the figure, adjacent insertion holes 31a, 31b, 3
The center-to-center distance L1, L2 of 1c is the distance between adjacent through holes 1.
The center-to-center distances 1 and 2 of 0a, 10b, and 10c are approximately equal to each other.

By the way, the through-holes drilled in the cab floor panel 1 may be shaped like the through-holes 10d, 10e, 10f shown in FIG. It's not necessarily in a straight line. In this case, since the connecting portions 35a and 35b of the coupled grommet 3 have flexibility, it can be used within the range of expansion and contraction of the connecting portions 35a and 35b.

Incidentally, if the through holes are not in a straight line, it goes without saying that the grommet 3 may be preformed to correspond to the arrangement of the through holes 10d, 10e, 10f.

Further, the grommet 3 has through holes 10a and 10.
The distance L1, L between the centers of the insertion holes 31a, 31b, 31c is greater than the distance L1, L2 between the centers of the insertion holes 31a, 31b, 31c.
2 is slightly larger than the connecting portion 35a,
Once the length of 35b is set, it can be used even if it is slightly different from the predetermined length due to errors due to variations in grommet molding.

The grommet 3A in FIG. 3 is a so-called cut-off type grommet in which a portion of the flange and fitting portion of each grommet portion is cut out, as indicated by the symbol S.
This grommet 3A can be attached to a harness or the like after the harness or the like is passed through a through hole (not shown) in the panel.

Note that, depending on the type of vehicle, harnesses and the like may not be routed through all the through holes, and certain through holes may become unnecessary, and these unnecessary through holes are usually closed with plugs. In such a case, as shown in FIG. 4, a grommet 3B connected to a part of a plug 30 for closing an unnecessary through hole (not shown) may be prepared and used. .

Although FIGS. 1 to 4 show a three-connected grommet having three insertion holes, it may be two-connected or four or more connected as required.

(Effect of the invention) As described above, according to the grommet of the invention,
When any one of the grommet parts is installed in the through hole of the panel, the other grommet parts are selected as the same, so there is no mistake, and work efficiency is improved.
