Pressure sensor with electrically conductive spring bodies for connecting and fixing connector case and pads

Abstract

A pressure sensor 1′ comprising a housing 10′ having a pressure introduction hole 12, a pressure sensing element 22 composed of a semiconductor element having piezoresistance effect, a holder 30 having fixed thereto the pressure sensing element 22, a guide member 98, a seal member 99 and a connector case 70, the pressure sensor element 22 and holder 30 joined in airtight manner to create a reference pressure chamber 72. On the holder 30 of the pressure sensor body is mounted a circuit board 40 having electrode pads, the electrode pads connected to connectors 80 fixed to the connector case 70 via conductive spring bodies 50. The guide member 98 supports holder 30, and in the opening 100 of the guide member 98 is placed the seal member 99.
