Patent ID: 7249572

Claim:
An electronic animal training device comprising: a receiver housing defining an interior of said receiver, an internally threaded opening extending between said interior of said housing and the ambient environment, said opening including an inner flange extending radially inwardly of said opening and defining an annular shoulder adjacent a proximate end of said opening, an wire antenna having a first portion disposed within said housing and extending through said housing, and a second portion extending beyond said housing, a resilient O-ring which is substantially impervious to moisture and liquids, interposed in encircling and frictional engagement with said first portion of said antenna in the region of said opening in said receiver housing, a circular retainer element having a central opening through the thickness thereof, said retainer element being disposed in encircling, non-physically engaging relationship to said antenna, an annular recess of generally semi-circular cross section defined in said central opening through said retainer element and adapted to receive and frictionally engage the outer surface of said O-ring at multiple locations about the outer circumference of said O-ring, said retainer element having external threads adapted to mesh with said internal threads of said opening through said receiver housing whereby said retainer element with said O-ring captured within said recess is threadably insertable into said opening in said receiver housing to compress said O-ring between said retainer, said shoulder and the outer circumferential wall of said first portion of said antenna to effect a flexible hermetic seal between said antenna and said O-ring.
