  • Sealing apertures through which electrical terminals protrude
    Patent number: 4246437
    Abstract: The apertures in one wall of an electrical component housing through which electrical terminals protrude are sealed with resin. The resin is applied to the housing wall at a remote area and caused to flow by capillary action along grooves to the required locations for sealing the apertures. In the case of a two part housing the parts of which join at the perimeter of the wall having the protruding terminals, the resin may also be caused to flow by capillary action into this join to seal it.
