Abstract:
1. A sensor assembly comprising: a sensor body comprising a sensing device connected to a sensor terminal; a sensor body insert comprising said sensor body and a sensor body molding made of a first thermoplastic material that covers at least a portion of said sensor body, wherein said sensor body molding comprises a sensor body cover that contacts and covers said at least a portion of said sensor body, and an arcuate ring of greater diameter than, and extending around and radially outward of, at least a portion of said sensor body cover forming an open space radially separating said arcuate ring from said sensor body cover; and a sensor housing made of a second thermoplastic material comprising a sensor housing cavity for receiving said sensor body insert, wherein said sensor housing cavity comprises an arcuate inner surface circumscribing said sensor housing cavity shaped to receive said arcuate ring of said sensor body molding, and a ridge circumscribing said sensor housing cavity proximate to said arcuate inner surface, wherein during assembly of said sensor assembly, said sensor body insert is pushed axially into said sensor housing cavity causing said ridge to apply a radial force on said arcuate ring, bending said arcuate ring toward said sensor body cover and allowing said arcuate ring to pass said ridge and be seated in said arcuate inner surface forming a spherical-type snap-fit.
