ABSTRACT:
An improved HF shielding feature is provided for electrical enclosures having a box-like base and a sealing cover wherein a tongue projects integrally from the upper periphery of the base into a groove formed integrally in under periphery of the cover. The tongue has a compression surface spaced apart from the base periphery, a first outside wall depends from such tongue compression surface to an outside portion of the base periphery and a first inside wall depends from the tongue compression surface to an inside portion of the base periphery. The groove has a second compression surface spaced apart from the tongue compression surface, a second outside wall depends from the groove compression surface to an outside section of the cover periphery and a second inside wall depends from the groove compression surface to an inside section of the cover periphery. A gasket is compressed between the tongue and groove compression surfaces, the inside wall of the groove is in contact with the inside portion of the base periphery and the groove outside wall is out of contact with any of the outside portion of the base periphery.
