High frequency electronic circuit null electricity and the electronic formative which

摘要

(57) Abstract Electricity and the electronic formative and it possesses that joint line (3), the printed circuit board (2) being the electronic circuit above, with the interference operation to the electronic circuit and the electronic circuit depending, the interference which it occurs encircling the aforementioned electronic circuit in order to prevent due to the reverse clipping housing, high frequency as for this invention, the printed circuit board (2) the joint line of the electronic circuit above (3) the reverse clipping housing (1) has gone outside in the electronic circuit in order is attenuated, to use for the combination indicatory instrument of the especially automobile, the reverse clipping housing (1,15) connecting means outside (5) to be jointed by the joint line (3), aforementioned reverse clippingTo the housing (1) invasion and it decides that the reverse clipping means which discharge of high frequency it decreases or suppresses, or are offered from the aforementioned reverse clipping housing of high frequency (1).
