ABSTRACT:
A liquid-tight seal is achieved in a two-part transformer casing by use of a U-shaped channel in the main body of the casing, the U-shaped channel being formed on one side by a rigid joint member and, on the other side, by a flexible member. Both members are molded in a single unit with the main casing, but the flexible member has a decreased cross-section relative to that of the rigid member. The cover for the casing has a lip extending into the U-shaped channel. The lip is wegge-shaped, having a minimum cross-sectional area at its furthest projection into the U. At its other extremity, the cross-sectional height of the lip slightly exceeds the perpendicular distance between the flexible and rigid members. A rectangular cross-sectional part of the lip immediately adjacent to the cover provides a contact surface for the flexible member, while the rigid member makes contact with the wedge-shaped portion over a greater area. The flexible member thus pushes the lip against the rigid member and, further, provides a backup seal should liquid pass through the seal between the lip and the rigid member.
