Abstract

PURPOSE:To enable a spherical body to freely correspond to the aligning direction of a linear/tubular member, by controlling the spherical body, through which the linear or tubular member is inserted, by means of a cover so that the member is positioned at a given insertion angle and securing the spherical body under this condition. CONSTITUTION:A linear/tubular member 2 is inserted through a through hole 14a in a spherical body 14, and the spherical surface of the spherical body 14 is brought into contact with a flange 1b of a panel 1. Thereafter, the linear/tubular member 2 is also inserted through a hole 17a in a tubular seal part 17 of a cover 15 which is formed so that the linear/tubular member 2 can be installed at a predetermined insertion angle, and a recess 16a in a retainer 16 is brought into contact with the spherical surface of the spherical body 14. The cover 15 is then attached to a panel 1 by means of a bolt 19, etc. This enables the spherical body 14 to be held between the flange 1b of the panel 1 and the retainer 16 of the cover in a condition to hold an angle which is previously set by means of the hole 17a in the tubular seal part 17 and at which the linear/tubular member 2 is inserted through the panel 1.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a glock 1- that seals a hole in a panel and maintains airtightness and watertightness when a wire/tubular member is inserted through the hole in the panel. , a grommet that can be effectively used in areas where a wire or tubular member is inserted diagonally into a hole in a panel, mainly in cab-type vehicles, or in cases where the wire or tubular member is mainly a speedometer cable. It depends.

Examples of conventional clocks 1 to 1 include those shown in FIGS. 1 and 2.

Reference numeral 1 designates a dash panel, which has an insertion hole 1a through which a wire/tubular member 2 is inserted. The grommet 3, which has a cylindrical body with a bellows-shaped through hole 3a through which the wire/tubular member 2 is inserted, is attached to the dash panel 1 by fitting its fitting portion 3b to the periphery of the hole 1a of the dash panel 1. It is being For example, the indoor iD side side line tubular member 2 is inserted into the through hole 3a of the chromet 3 from the engine route side.

Note that 4 is a sound insulating cover and 5 is an I-rim.

However, when the wire/tubular member 2 is inserted diagonally through the dash panel 1 as shown in FIG. When inserted, the grommet 3 is deformed in accordance with the direction in which the wire/tubular member 2 is disposed. Therefore, A when the bellows is stretched
In this case, the grommet 3 rose from the dash panel 1, resulting in a problem that the sealing performance of the grommet 3 deteriorated.

Also, in the state shown in Figure 2, place Gromeso 1-3 on panel 1.
Installation workability is also poor because it has to be installed on the
If the grommet 3 is not completely secured, the grommet will not be able to maintain its original function of airtightness and watertightness, and if the grommet 3 is not completely damaged, the grommet 3 will come off due to vibrations such as when the vehicle is running. There was a problem.

This invention was made by focusing on such conventional problems, and a through hole is drilled through which a wire/tubular member is inserted.
Also, the insertion angle of the inserted wire/tubular member into the panel can be freely adjusted, and the spherical body is brought into contact with the hole in the panel, and the spherical body that is inserted into the panel and inserted through the wire/tubular member is inserted at a predetermined insertion angle. The purpose of this invention is to solve the above problems by constructing a grommet from a cover that regulates and fixes the grommet.

The present invention will be explained below based on the drawings.

FIG. 3 is a diagram showing an embodiment of the present invention.

First, to explain the configuration, the grommet 13 includes a sphere 14 integrally molded from an elastic material such as rubber, and a cover that regulates and fixes the sphere 14 into which the wire/tubular member 2 is inserted into the panel 1 at a predetermined insertion angle. It consists of 15. A through hole 14a is bored through the center of the sphere 14 through which the wire/tubular member 2 is inserted, and this through hole 14a is provided with irregularities to improve the sealing performance with the wire/tubular member 2. ing. This uneven through hole 14a can be easily obtained by inserting a soft insert 1 suitable for the through hole into a mold in advance, forming a sphere, and then pulling out the soft insert to one side. The cover 15 has four hemispherical parts 1 that abut the spherical surfaces of the sphere 14 and regulate and fix the sphere 1, /I at a predetermined angle.
6a is formed, and the wire/tubular member 2 is inserted into a predetermined portion of the support portion 16, that is, a portion corresponding to a desired insertion angle of the wire/tubular member 2 into the panel 1. A cylindrical seal portion] 7 having a hole 1.7a is provided. The cover 15 is attached to the panel 1 via the backing 20 and the bolts 1 are attached to the periphery of the support portion 16.
A fixing part 18, which is attached with 9 or the like, is extended.

The periphery of the insertion hole 1a of the panel 1 is bent toward the indoor ID side,
A flange 1b is formed that contacts the spherical surface of the sphere I4 and seals the indoor ID side and the engine room ER side.

Next, the action will be explained.

First, the L-wire/tubular member 2 is inserted through the through hole 14a of the sphere 14, and the spherical surface of the sphere 14 is brought into contact with the flange 1b of the panel 1. After that, the cylindrical seal part 17 is formed to attach the wire/tubular part 2 at a predetermined insertion angle.
The wire/tubular member 2 is also inserted through the hole 17a of the support part 16.
The concave portion 16a is brought into contact with the spherical surface of the sphere I4.

Next, a backing 20 is placed between the panel 1 and the fixed part 18.
The cover 15 is attached to the panel 1 with bolts 19 or the like. Then, the sphere 14 is inserted into the flange 1 of the panel 1 while the preset insertion angle of the wire/tubular member 2 into the panel l is maintained by the hole 17a of the cylindrical seal part 17.
b and the supporting portion 16 of the cover. Therefore, the interior ID side and the engine room ER
The side refers to the close contact between the flange 1b and the spherical surface of the sphere 14, the line and
The tubular member 2, the convex portion of the through hole 14a, and the cylindrical seal portion 17
, the spherical surface of the sphere 14 and the concave portion 16a of the support portion 16 , and the panel 1 and the fixing square portion 18 are in close contact to achieve a complete seal.

In addition, the insertion angle of the wire/tubular member 2 into the panel 1 is determined depending on the position of the cylindrical seal portion 17.
Since it can be brought into sliding contact with b, it can be set freely. Therefore, the sphere can be shared. Furthermore, since the sphere 14 and the cover 15 are not damaged, their sealing performance is not degraded. Also,
It goes without saying that the cover 15 functions as the sound insulating cover 4 in the conventional example.

In the above, the sphere 14 is not limited to being molded from an elastic material, but any material may be used as long as the sealing property is improved, and the through hole ]/Ia does not necessarily have irregularities. Of course, it is not necessary.

Further, although the sphere 14 is sandwiched between the support portion 16 and the flange 1b, it is needless to say that the present invention is not limited to this.

As described above, according to the present invention, the grommet is provided with a through hole through which the wire/tubular member is inserted, and the insertion angle of the inserted wire/tubular member into the panel is freely adjustable. It consists of a sphere that comes into contact with the hole, and a cover that is attached to the panel and regulates and fixes the sphere through which the wire/tubular member is inserted at a predetermined insertion angle, so it is flexible in the direction in which the wire/tubular member is installed. This grommet can be used for all vehicles. Furthermore, since the grommet is not deformed when it is attached to the panel, its sealing performance is not degraded, and furthermore, there is an effect that no problems occur due to problems in the attachment work.
