Abstract
A semiconductor sensor (10) is built into a cable connector to provide rapid and reliable attachment of the semiconductor sensor (10) into a monitoring or control system. The sensor (10) is mounted in a package (11) having cable connector leads (12, 13, 14) extending through the package (11). The semiconductor sensor (10) is electrically attached to the cable connector leads (12, 13, 14). A housing (20,30) surrounds the package (11) and provides a protective shroud for the cable connector leads (12, 13, 14).
Claims5
A pressure sensor built into a cable connector, comprising:
- a semiconductor pressure sensor that is on a semiconductor chip which also includes an analog-to-digital converter, a resistor bridge, an amplifier and temperature compensation;
- a pressure sensor package for receiving the semiconductor pressure sensor, wherein the pressure sensor package has walls through which cable connector leads extend, the walls forming an enclosure for the semiconductor pressure sensor and the semiconductor pressure sensor being wirebonded to the connector leads:
- and
- a housing for enclosing the pressure sensor package, the housing providing a protective cover for the connector leads, and the connector leads being for directly receiving a cable connector, and wherein the housing has a port for conveying an external pressure to be measured to the pressure sensor.
A cable connector and semiconductor sensor combination, comprising:
- a semiconductor sensor;
- a package for the semiconductor sensor having walls surrounding the semiconductor sensor and having cable connector leads extending through the walls, wherein the semiconductor sensor is electrically connected to the cable connector leads by wire bonding;
- and
- a housing surrounding the package and forming a protective cover for the portion of the cable connector leads extending through the walls, the housing having a top portion and a bottom portion, wherein the top portion and bottom portion are held in a fixed relationship.
