Fluid pressure sensor
First Claim
1. A sensor for sensing a pressure associated with a fluid comprising:
- a port body including;
a distal end defining an axial passage for receiving the fluid; and
a first sidewall extending from the distal end and terminating in a proximal crimp portion defining an opening;
an electrical connector including a shoulder extending through the opening with a flexible flange within the port body, the electrical connector and the port body defining an interior for a plurality of components; and
a support ring in the interior, the support ring having an upper surface with a radially inward ledge that acts as a stop for the shoulder and, in turn, sets a gap between the upper surface and the flexible flange,wherein the proximal crimp portion is crimped down on the flexible flange to form an upper seal.

Abstract
A sensor includes a port body which defines an axial passage for receiving fluid. An electrical connector extends through an opening in the port body near a crimp portion opposite the axial passage and forms an upper seal with the port body. Within the interior of the port body, a support ring and base cover form a cavity which retains a sensing element. The sensing element is exposed to the fluid within the axial passage and determines the pressure. An annular seal is retained by the base cover. The crimp portion of the port body is crimped to provide an upper seal and apply a force on the components within the interior, pinching the annular seal between the sensing element and the base of the port body to create a lower seal.

6. An assembly for sealing a passageway with a fluid passing therethrough, the assembly comprising:
-
a first body including;
a distal end defining an axial passage;
a first sidewall extending from the distal end to define an interior; and
a skirt defining an axial bore and having a ledge extending radially inward from the skirt and terminating in two opposing annular ridges to form a recess therebetween;a second body; and an annular seal seated at least partially within the recess, wherein when the annular seal is compressed between the first body and the second body, the interior is sealed from the fluid. - View Dependent Claims (7, 8, 9, 10, 11)
