摘要

The production of a pressure sensor (1) useful as an interference suppression kit in the vehicles, comprises encapsulating the pressure sensor partly with two-component micro-cellular foamed plastic. The pressure sensors hanging together in grid form, are encapsulated and subsequently separated from one another. Electrical functional elements are attached on a metal sheet and are assigned to a printed circuit board. The boards are punched out under forming contact legs and are encapsulated with the plastic under release of contact legs and the boards are separated from one another. The production of a pressure sensor (1) useful as an interference suppression kit in the vehicles, comprises encapsulating the pressure sensor partly with two-component micro-cellular foamed plastic. The pressure sensors hanging together in grid form, are encapsulated and subsequently separated from one another. Electrical functional elements are attached on a metal sheet and are assigned to a printed circuit board. The boards are punched out under forming contact legs and are encapsulated with the plastic under release of contact legs and the boards are separated from one another. Electrical cable (4) is attached at the sensors before the encapsulation. The connection ends of the cable are encapsulated area wise. The enclosing of the pressure sensor from a carrier plate is formed for the supporting the pressure sensor from a hard plastic. A pressure area (3) is formed for actuating the pressure sensor from a soft plastic. An independent claim is included for a pressure sensor enclosed with plastic.
