Abstract

An antenna assembly for mounting an antenna on a vehicle body, especially upon the roof of a vehicle, in which the assembly has a base body of metal with a threaded projection passing through a hole in a wall of the vehicle body. A housing of plastic encloses the antenna components mounted upon a plate-shaped portion of the base body and a seal is provided between the base body and the vehicle body and seals around the opening between the base body and the wall of the vehicle. The seal can be injection molded and molded onto the base body in the injection-molding process.

Claims

1. An antenna assembly for mounting upon a wall of a vehicle body, comprising:

a base body composed of metal and having a plate-shaped portion adapted to be juxtaposed with said wall;

a housing composed of plastic and enclosing antenna elements mounted upon said base body; and

a seal between said plate-shaped portion and said wall and sealing said base plate relative to an interior of the vehicle body.

2. The assembly defined in claim 1 wherein said seal is injected molded and is at least in part fitted on said base body.

3. The assembly defined in claim 2 wherein said seal is formed by one component or multiple components by injection molding.

4. The assembly defined in claim 1 wherein said seal has a part sandwiched between a surface of said wall and said plate-shaped portion.

5. The assembly defined in claim 4 wherein said plate-shaped portion is provided with a projection extending through a hole in said wall and said seal extends around said projection.

6. The assembly defined in claim 5 wherein said seal hugs said projection.

7. The assembly defined in claim 6 wherein said seal extends along and closely surrounds said projection.

8. The assembly defined in claim 6 wherein said seal is formed with a substantially circular cross section bead surrounding said projection.

9. The assembly defined in claim 8 wherein said seal is provided with an outer bead engaging said wall.

10. The assembly defined in claim 9 wherein said seal is provided with portions between said beads projecting through openings formed in said plate-shaped portion.

11. The assembly defined in claim 10 wherein said plate-shaped portion is provided with a pair of annular ridges flanking said opening in said plate-shaped portion.

12. The assembly defined in claim 5 wherein said projection is threaded, said assembly further comprising a nut threaded onto said projection and clamping said plate-like portion against said seal and said wall.

13. The assembly defined in claim 12 wherein said seal is provided with an inner bead surrounding said hole and sealing against said wall around said hole.

14. The assembly defined in claim 13 wherein said seal has an outer bead bearing against said wall and, between said beads, formations projection through openings in said plate-shaped portion.
