US Patent 7484417 Pressure sensor and manufacturing method of the same

A pressure sensor includes: a main body case including a housing (1) and a joint (2); an electronic circuit (3) housed inside the main body case to convert detected pressure into electrical signals to send out; a connecting metal piece (5), one end (51)of which abuts on an electrode (31) of the electronic circuit (3); a terminal (4), one end (41) of which is joined to the other end (52) of the connecting metal piece (5) and the other end (42) of which is disposed outside the main body case; and a cushion (7) biasing the one end (51) to the electrode (31). The one end (51) and the electrode (31) are electrically connected by biasing force of the cushion (7), which eliminates welding, enabling manufacturing at low cost.
