Description

[Detailed Description of the Invention] (1) Technical Field of the Invention The present invention relates to the shape of a rubber packing, and particularly to the shape of a rubber packing configured to prevent water from entering from the outside.

(2) Conventional technology and problems When using a personal radio or receiving FM broadcasts, a dedicated antenna is attached to the radio. For example, when installing the above-mentioned antenna (trunk lid antenna) on a car, the antenna is usually installed outside the car body, but the feeder line (hereinafter referred to as the feeder) connected to the antenna is sandwiched between the trunk door and the like and inside the car. and connected to a wireless device, etc. At this time, a rubber packing as shown in FIG. 1 is attached to the portion of the feeder sandwiched between the trunk door and the vehicle body to prevent water from entering the trunk during rain. In the figure, 1 is a feeder and 2 is a rubber packing. FIG. 2 is a cross-sectional view of such a feeder fitted to the trunk door and body of a car, where 3 is the trunk door, 4 is the car body, 5 is a protrusion provided on the trunk room 7 side of the car body 4, and 6 is a rubber (hereinafter referred to as a weather strip) provided at the end of the protrusion 5 to prevent water from entering the trunk compartment 7. Figure 3 is A in Figure 2.
-A' sectional view, and parts equivalent to those in FIGS. 1 and 2 are given the same reference numerals. As is clear from FIGS. 2 and 3, the weather strip 6 is sufficiently pressed near the feeder 1 by the rubber packing 2, so there is no gap between the rubber packing 2 and the feeder 1.
At both ends, that is, at the boundary between the rubber packing 2, the trunk door 3, and the weather strip 6, the weather strip 6 is not properly pressed down, so a slight gap 8 is created, and water enters from the gap 8. There was a problem with coming.

(3) Purpose of the invention The present invention was devised in view of the above-mentioned drawbacks of the prior art, and aims to provide a rubber packing that can more reliably prevent water from entering the trunk from the outside.

(4) Structure of the invention According to the present invention, the invention has a fitting hole into which a power supply line is fitted, and uneven portions formed at both ends substantially parallel to the fitting hole, This is achieved by providing a rubber packing that is configured to become thinner as it approaches the uneven portion from the hole.

(5) Embodiments of the invention Examples of the invention will be described below with reference to the drawings.
FIG. 4 is a perspective view showing an embodiment of the present invention,
In the figure, 9 is a rubber packing, 10 is a fitting hole into which the feeder is fitted, 11 is a recessed portion, and 12 is a convex portion.
FIG. 5 is a sectional view taken along line BB' in FIG. 4.
In this figure, parts that are equivalent to those in FIG. 4 are given the same reference numerals. As is clear from FIGS. 4 and 5, a fitting hole 10 is formed in the center of the rubber packing 9, and uneven portions 11 and 12 are formed at both ends of the rubber packing 9, approximately parallel to the fitting hole 10. . The thickness of the rubber packing 9 decreases as it approaches the concavo-convex portions 11 and 12 from the fitting hole 10, and becomes the thinnest at the tip of the convex portion 12.

The rubber packing 9 configured as described above is attached to the feeder and the trunk door 3 is installed as shown in Fig. 2.
When the weather strip is fitted on the vehicle body 4, first, there is no gap in the vicinity of the fitting hole 10 because the weather strip is sufficiently pressed down. Further, the weather strip 6 is press-fitted into the recess 11 at both ends of the rubber packing 9, and the path through which water enters is blocked by the press-fit weather strip 6 and the convex portions 12 located on both sides thereof.

Incidentally, although the above embodiments have been described as being applied to a vehicle, particularly to a trunk door of a vehicle, the present application is not limited thereto.

(6) Effects of the invention As explained above in detail, according to the present application, by forming uneven parts on both ends of the rubber packing, the weather strip is press-fitted into the recessed parts and the protruding parts located on both sides thereof. Since the water intrusion path is blocked, water intrusion can be prevented even more reliably.
