Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a grommet that is attached to a panel through which piping and wiring pass.

[Prior Art] Grommets are used to support piping and wiring when they are installed through a panel of an automobile or the like.

Grommets have already been proposed by the present applicant in, for example, Japanese Utility Model Application Publication No. 56-15, but in the conventional grommet, it was necessary to use one grommet for each piping and wiring. Therefore, when a plurality of pipes or wires pass through a panel, holes must be drilled for each, which is cumbersome.

Further, Japanese Utility Model Publication No. 57-22653 discloses a grommet having two holes in a substrate. However, such known techniques are limited in number, lack versatility, and can only be applied in specific cases.

[Problem to be Solved] Therefore, the purpose of the present invention is to provide a grommet that can be universally applied to panels of automobiles, etc., and can be implemented regardless of the number of wiring or piping.

[Means for Solving the Problems] According to the present invention, in a grommet that is attached to a panel through which wiring and piping pass, a plurality of divided grommet elements are provided in accordance with the number of wiring and piping that pass through the same through hole. , a part of the outer periphery of the grommet element has an engaging portion with each other, and each grommet element can engage with each other, and the remaining portion of the outer periphery has an engaging portion with the panel. and can be freely engaged with the inner periphery of the panel.

[Explanation of effects] Therefore, since the number of wiring and piping is predetermined during assembly, grommet elements corresponding to that number are prepared, and the grommet is attached to the panel with those grommet elements assembled. Make a hole large enough to install it. and the wiring,
Among the grommet elements through which the piping is inserted, the end grommet elements are engaged with the inner periphery of the panel, and the other grommet elements are engaged with each other. The operation is therefore very simple and the grommet elements can be firmly engaged with each other.

[Example] Hereinafter, an example of the present invention will be described based on the drawings.

Figure 1 shows the case where the present invention is applied to a vehicle such as an automobile, in which a plurality of pipes 2, 3, graces or harnesses 4 are piped and wired through a panel 1 in the passenger compartment of the vehicle. ing.

These pipes are, for example, air conditioner piping, and the harness is an electric wire connected to the battery 5.

The grommet 10 of the present invention is used to support these piping and wiring to the panel 1.

Details of the grommet 10 are shown in Figure 2 and below, and the grommet of the present invention has several elements 1
It is divided into 1, 12, and 13 parts, and some elements are used in combination depending on the purpose of use.

That is, the element 11 is made of a rubber material having a hole 11a in the center through which the tube 2 passes, and supports the tube 2 flexibly by using the ribs. One side portion 11b of the element 11 has a groove portion that engages with the opening edge of the panel 1, and the other end portion 11c is formed in a shape that can be engaged with and detached from another adjacent element 12.

That is, the element 12 also has a hole 12a in the center that supports the tube 3, and a side 12b that joins to the element 11 side.
is formed in a shape to engage with the side portion 11c of the element 11, and the other side 12c is formed in a shape to be joined to the next element 13.

The shape of this joint is shown in FIG. 4, for example. One side 12c is formed to have a circular cross section, and the other side 13b is formed to have a circular groove in cross section. good. Then, it can be engaged and disengaged by utilizing the flexibility of the rubber material.

The shape of this engaging/disengaging portion may be a convex portion 22c and a concave portion 23b having a rectangular cross section as shown in FIG.

The element 13 has a hole 1 in the center through which the cable 4 passes.
3a, one side 13b engages with the element 12, and the other side 13c engages with a portion of the panel 1.

Since the grommet of the present invention is used by combining a plurality of elements in this way, if only the pipe 2 and cable 4 are to be passed through one opening, only the elements 11 and 13 should be combined as shown in FIG. Just use it.

As described above, according to the present invention, the following excellent effects are achieved.

(1) Since the grommet that supports the pipes and cables is made into a split type, multiple elements can be combined to form one grommet in one hole in the panel as needed.

(2) It is easy to work and can reduce the grommet installation space and assembly man-hours.

(3) Grommet elements of several sizes can be prepared in advance, allowing parts to be shared.

(4) This improves versatility.
