초록 ▼

In order to provide environmental protection, a leadless sensor of the type having a central boss is secured within a composite metal housing consisting of a top metal housing having a central boss which communicates with the central boss of the sensor. The top housing has a thin top portion surrounded by a peripheral portion, which peripheral portion is epoxied or otherwise secured to a bottom metallic housing having an internal hollow for accommodating the pressure sensor and the glass backing wafer, both of which are secured to a header which accommodates terminal pins associated with the active elements on the sensor device.

대표청구항 ▼

1. A pressure sensor, comprising: a first cylindrical metal member having a closed top surface and an opened bottom surface, said closed top surface having a central boss extending towards said open bottom surface, a second cylindrical metal member having an inner recess surrounded by a flange, with the outer surface of said second cylindrical member secured to the periphery about said open bottom surface of said first cylindrical member, a leadless semiconductor sensor having a central boss surrounded by an active deflecting region to enable said sensor to produce an output when a pressure is applied to said semiconductor sensor boss, said sensor positioned on an insulator support member and located in said inner recess of said second cylindrical member with said support member positioned on said flange, with said central boss of said sensor in contact with said central boss of said first cylindrical member to cause a force applied to the closed top surface of said first cylindrical member to be applied to said sensor via said associated bosses. 2. The pressure sensor according to claim 1 wherein said second cylindrical metal member is secured to said first cylindrical member by an epoxy bond. 3. The pressure sensor according to claim 1 further including terminal pins extending from the inner recess of said second member and connected to said sensor to provide contact areas for said sensor. 4. The pressure sensor according to claim 1 wherein said central boss of said first cylindrical member is affixed by means to said central boss of said sensor. 5. The pressure sensor according to claim 4 wherein said means is an epoxy bond. 6. The pressure sensor according to claim 1 wherein said insulator support member is fabricated from glass. 7. The pressure sensor according to claim 1 wherein said insulator support member is fabricated from plastic. 8. The pressure sensor according to claim 1, wherein said second cylindrical member has a peripheral wall extending from said flange and positioned to surround said leadless semiconductor sensor and said insulator support member. 9. The pressure sensor according to claim 1 wherein said first housing is stainless steel. 10. The pressure sensor according to claim 9 wherein said second housing is stainless steel.
