ABSTRACT:
A releasable locking and sealing assembly for a cylindrical casing which fits over a body. The body includes a cylindrical portion about which an O-ring formed from a stiffly deformable, springy material is disposed. The casing is dimensioned to compress the O-ring as it is slid over the body, and includes an annular groove around its interior cylindrical wall, the width of the groove being no greater than the width of contact between the casing wall and the O-ring when compressed. When aligned with the groove, an annular portion of the O-ring is crimped to form a seal between the body and casing which resists axial movements of the casing relative to the body. However, the seal yields to an axial force coupled with a twisting force on the casing, thereby permitting the casing to be locked in sealing relation to the body but readily removed when desired. The invention is of particular usefulness in a linear motion potentiometer.
