Sensor housing assembly
A sensor housing assembly for enclosing an electrical interface circuit, a sensor or sensor input, and a connector for interfacing with a data unit. The sensor housing assembly generally includes a housing containing a circuit board and interface circuitry to condition a sensor input signal, and a connector mounted on the circuit board, the assembly being insertable into a data unit. The housing can include a protrusion that prevents the assembly from being inserted into the data unit incorrectly, which also allows a symmetrical connector to be used. The sensor housing assembly is adapted to be inserted into a receptacle in the data unit, which has blocking tabs that act with the protrusion to ensure that the assembly can only be inserted one way.
1. A sensor housing assembly adapted for insertion into a data unit receptacle, comprising:
a circuit board comprising an electrical interface circuit that accepts a sensor signal and generates an output corresponding to the sensor signal;
a pressure sensor mounted on the circuit board;
a connector mounted on the circuit board and conductively coupled to the output, the connector comprising a first plurality of conductive elements; and
a housing substantially enclosing the circuit board, the housing comprising a first elongated side and a second elongated side opposite the first elongated side, the housing further comprising a first opening at a first end adapted to allow the connector to be mated to a complementary connector of the data unit, the complementary connector having a second plurality of conductive elements configured to mate with the first plurality of conductive elements;
wherein the housing comprises a second opening at a second end for receiving a tube for carrying a pressure to the pressure sensor; and
wherein the first elongated side is adapted to contact a surface of the data unit receptacle and wherein the second elongated side includes a protrusion to prevent the housing from being inserted with the second elongated side adjacent to the surface.
2. The sensor housing assembly of claim 1 , wherein the first elongated side and the second elongated side are parallel to each other.
3. The sensor housing assembly of claim 1 , wherein the housing surrounds the connector on four sides.
4. The sensor housing assembly of claim 1 , wherein the first plurality of conductive elements are symmetrically arranged.
5. The sensor housing assembly of claim 1 , wherein the first plurality of conductive elements are female.
6. The sensor housing assembly of claim 1 , wherein the protrusion comprises a curved surface.
7. The sensor housing assembly of claim 1 , wherein the protrusion comprises a cylindrically-shaped surface.
