EMS filter for mine - inhibits electro-magnetically caused interference fields with circuit board on side turned away from filter, having large area conductor surface connected to ground

摘要

The filter surrounds the trigger circuit (7) for the explosive content (6) of a mine, and has at least one filter (9,10) arranged on a conductor plate (8), connected to an external signal source (11). The circuit board on its side turned away from the filter has a large area conductor surface connected to ground, which covers the total surface of the board. The ground connections of the filter (9,10) are connected to the conductor surface. The filter is a rod-shaped integrated component which has at least one band of material connected to ground encompassing it. The external signal source (11) is a sensor, e.g. a movement or contact sensor, and the filter is a low pass filter. The conductor plate (8) has at least one pin socket for accommodation of contacts. USE/ADVANTAGE - For military applications. Prevents accidental triggering of mine.
