Abstract

PURPOSE:To make it possible to shield the whole of a semiconductor pressure transducer from the outside electro-magnetic wave by bending a ground plate installed at the terminal section and completely covering the cut-out portion in a shield cover that is made for the work of connecting lead wires. CONSTITUTION:A shield case 9 that accomodates a semiconductor strain gauge 1 and a circuit substrate 8 and a shield cover 12 on which a condenser 16 for penetrating terminal is mounted are set up independently. A cut-out section 14 for the work of connecting the substrate 8 and a terminal 15 is provided to this cover 12. A grounding plate 17 is attached to the grounding side of the condenser 16 and after the cover 12 is molded to a housing 18 with the condenser 16, and the case 9 that accomodates the gauge 1 and the substrate 8 is mounted on the inside of the housing 18, the case 9 and the cover 12 are connected and at the same time connection of the substrate 8 and the condenser 12 is made by a lead wire between them by means of the cut-out section 14 that is provided in the cover 12. After welding the cover 12 and the grounding plate 17 the grounding plate 17 is bent to cover the cut-out section 14 to effect complete shielding.
