Method and apparatus for attaching a sensor assembly in a control unit

摘要

A control unit for a safety restraint device includes a main printed circuit board that supports lateral and vertical acceleration sensors and an auxiliary printed circuit board that supports rollover sensors. The main and auxiliary printed circuit boards are spaced apart from and are positioned in an overlapping relationship to each other within a housing. A pin connection provides electrical connection between the main and auxiliary printed circuit boards to permit signal transfers between the main and auxiliary printed circuit boards. A common fastener is used to connect both the main and auxiliary printed circuit boards to the housing. A cover is used to enclose the main and auxiliary printed circuit boards within the housing. The fastener extends through the cover, through both the main and auxiliary printed circuit boards, and finally into the housing.
