Abstract

A device for monitoring tire pressure includes an antenna for transmitting pressure data, a printed circuit board with a circuit for measuring and transmitting pressure data that is connected to the antenna, a power source for supplying the circuit, and a housing surrounding the printed circuit board, According to the invention, the housing is produced by insert-molding the antenna.

Claims

1. A device for monitoring tire pressure, comprising:

an antenna for transmitting pressure data;

a printed circuit board, connected to the antenna, having a circuit for measuring and transmitting pressure data;

a power source for supplying the circuit; and

a housing surrounding the printed circuit board, said housing is produced by insert-molding the antenna.

2. The device according to claim 1, wherein the antenna comprises press-fit pins that protrude from a housing wall and are pressed into metallized holes of the printed circuit board, so that the antenna is connected by means of a pressing technique to the circuit carried by the printed circuit board.

3. A device according to claim 1, wherein the antenna is a magnetic antenna.

4. The device according to claim 3, wherein the magnetic antenna is formed by a metal bracket embedded in a housing wall.

5. A device according to claim 1, wherein the power source and the printed circuit board are disposed on top of one another in the housing.

6. A device according to claim 1, wherein a spacer plate is disposed between the power source and the printed circuit board.

7. A device according to claim 1, wherein the power source is disposed on the side of the printed circuit board which faces away from the antenna.

8. A device according to claim 1, wherein the housing comprises undercut detent elements, which grip the power source.

9. A device according to claim 1, wherein the printed circuit board is embedded into a potting compound.

10. A device according to claim 1 wherein the printed circuit board is embedded into a potting compound.
