Method of producing a sensor subassembly, and sensor subassembly

DETAILED DESCRIPTION It is accordingly an object of the invention to provide a method of producing a sensor subassembly, and a sensor subassembly which overcome the above-mentioned disadvantages the prior art methods and devices of this general type, in particular a sensor subassembly which can be used in occupant protection systems of motor vehicles, which, with the capability of simple implementation, permits the costeffective production of sensor subassemblies which can be adapted to different requirements and operate reliably.
The invention is further based on the object of providing a sensor subassembly that can be produced cost-effectively in large numbers, can be adapted to the different requirements and has a high reliability.
With the foregoing and other objects in view there is provided, in accordance with the invention, a method of producing a sensor subassembly, which includes producing a plastic base part having a sensor holding region and a connection region; fastening a printed circuit board to the plastic base part; fitting a sensor element to the plastic base part and providing sensor connections for producing an electrical connection between the sensor element and the printed circuit board; and placing plug connections that extend from the connection region to the printed circuit board for providing an electrical connection between the printed circuit board and the plug connections.
A significant feature of the method according to the invention is based on the fact that a printed circuit board is fastened to the finished base part.
It being possible for the printed circuit board to be equipped to correspond to the respective requirements, so that, in spite of different sensor elements and printed circuit boards with different equipment or different configurations, the same base part can be used in large numbers for the different configurations.
The tolerances on the sensor subassembly are reduced to a minimum by the prefabricated base part having the sensor holding region and the connection region
