Pressure sensor
First Claim
1. A pressure sensor comprising a housing having a pressure introduction hole, a pressure detecting element formed of a semiconductor device having a piezoelectric resistance effect, a holder for fixing the pressure detecting element, and a connector case, the pressure detecting element and the holder being airtightly joined to form a pressure sensor body in which an interior space is defined, whereina circuit board having an electrode pad is provided on the holder of the pressure sensor body;
- a connector in the connector case and the electrode pad are connected by means of an electrically conductive spring body having elasticity; and
the holder is supported in the housing by means of a guide frame and a first O-ring and a second O-ring, the holder and the guide frame contacting one another with the first O-ring contacting the holder and the guide frame and the second O-ring contacting the holder and the connector case.

Abstract
A pressure sensor comprises a housing having a pressure introduction hole, a pressure detecting element formed of a semiconductor device having the piezoelectric resistance effect, a holder for fixing the pressure detecting element, and a connector case. The pressure detecting element and the holder are airtightly joined to form a pressure sensor body in which an interior space is defined. A circuit board having an electrode pad is provided on the holder of the pressure sensor body, and a connector in the connector case and the electrode pad are connected by means of an electrically conductive spring body having elasticity. The holder is supported in the housing by means of a guide frame and an O-ring.
