Abstract

In some circuit modules, an upper enclosure part and a lower enclosure part are joined with a sealing ring located between oppositely facing flanges on the two parts. The sealing ring has a generally square shape with rounded corners as seen looking downward into a plane of a flange. It has e.g. a C shape in section as seen looking horizontally parallel to the plane of a flange, and the upper and lower surfaces of the C shape form a sealing contact with the two flanges. Before the seal and the two parts are assembled, wax is applied to the sealing ring by means of a wax dispensing tool and a structure that holds the sealing ring and guides the wax dispensing tool.
