Patent ID: 8492652

Claim:
A junction box for connecting to a sensor assembly of a probe, the sensor assembly having a housing and a plate, the junction box comprising: a plurality of walls, one of the walls comprising: an opening configured to accept insertion of the housing; a mating area on an interior surface of said one of the walls, wherein the mating area comprises a perimeter encompassing the opening and wherein the mating area is sized and shaped to be congruent with the plate; at least two stopper walls each projecting from the interior surface of said one of the walls and aligned proximate the perimeter of the mating area to obstruct the plate from rotating in a first rotational direction out of an assembled position; at least two retaining flanges, wherein each of the at least two retaining flanges projects from one of the stopper walls and extends over the mating area at a distance offset from the interior surface of said one of the walls to obstruct the plate from moving out of the assembled position in a direction perpendicular to the interior surface of said one of the walls; and at least one retainer spring comprising an interior edge aligned in a plane proximate the perimeter of the mating area and projecting outward from the interior surface of said one of the walls, wherein the at least one retainer spring is elastically deformable and configured to be pressed toward the interior surface of said one of the walls during assembly without permanently deforming and to return to a non-flexed position when the plate reaches the assembled position to obstruct rotation of the plate in a second rotational direction opposite the first rotational direction out of the assembled position.
