Description

[0002] The fatigue driving detection monitoring camera requires two circuit boards to realize its functions, namely the LED circuit board and the sensor circuit board. There are two major problems that need to be solved when designing the structure: shielding problem and improving the utilization rate of the circuit board. The existing technology solves the shielding problem by attaching conductive foam to the periphery of the board-end connector for shielding. The foam is relatively small and needs to be bonded to different step surfaces of the half-section connector, which makes the assembly of the foam time-consuming and labor-intensive. When the foam size is relatively large, it is not easy to control the deformation, which requires further improvement of the existing foam shielding structure. Summary of the invention
