Abstract
A robust, easy to mount probe sensor includes an elongated body enclosing a sensor element and an integral flange extending away from the body. The body and flange are formed of material having a relatively low characteristic yield point. First and second generally parallel closely spaced through passages extend through the flange. An insert formed of material having a relatively high characteristic yield point is disposed in one of the passages. A fastener including a shank portion which extends through the other passageway includes an enlarged head which overlays the insert containing passageway and engages an attachment structure to effect directed compressive loading of the probe sensor flange.
Claims24
In combination:
- an electromechanical device, such as a probe sensor, including a body portion and a flange extending there from, said flange defining opposed, generally parallel surfaces;
- first and second passageways within said flange, each said passageway interconnecting said parallel surfaces;
- a metal insert member disposed within said first passageway;
- and
- a fastener including a head portion substantially overlaying said first passageway and a shank portion extending through said second passageway and operative, in application, to interconnect said head portion with a substantially fixed attachment structure, and thereby to effect substantial compressive loading on said insert member.

A probe sensor assembly comprising:
- an elongated body enclosing a sensor element adjacent one end thereof;
- a flange integrally formed with said body adjacent an opposed end thereof and extending outwardly there from, said body and flange formed from a material having a relatively low characteristic yield point, said flange defining generally parallel upper and lower surfaces;
- first and second tangentially adjacent through passages interconnecting the upper and lower surfaces of said flange;
- an insert member fixedly disposed within first through passage and extending substantially entirely there through, said insert member formed of a material having a relatively high characteristic yield point and defining an upper abutment surface disposed substantially coplanar with said upper flange surface and an opposed lower abutment surface disposed substantially coplanar with said lower flange surface;
- and
- a fastener integrally formed of a material having a relatively high characteristic yield point including a head portion integrally formed with an elongated shank portion, said shank portion extending through said second through passage and operative, in application, to interconnect the head portion with a relatively fixed attachment structure, said head portion defining a lower surface which extends radially sufficiently to substantially overlay said first through passage and form an abutting relationship with the upper abutment surface of the insert member and thereby to effect substantially compressive loading on said insert member.
