NON-RIGID CONDUCTOR LINK MEASUREMENT SENSOR AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to electronic sensors comprising an electromechanical microsensor cell such as a microaccelerometer. The invention more specifically relates to the mounting of a the microsensor cell (10) in a housing comprising inter alia a printed circuit board (30) including electronic processing circuits associated with the microsensor cell. In order to ensure a non-rigid electronic connection between a conducting contact plate (34) of the board (30) and a connection pin (12) of the cell (10), a conductor link is welded in the form of a narrow ribbon cut by chemical machining in a thin, flexible metal sheet (CuBe). The ribbon comprises at least one circular arc shaped segment (51) extending over a two-quarter or three-quarter turn. The elasticity thereof results in extremely low rigidity in all directions and thus prevents transmission of vibrations or shocks to the cell. It is possible to collectively manufacture all of the sensor links and successive mass-produced sensors. The invention can be applied to accelerometers subjected to the high stress from shocks and vibrations.
