Abstract
A method and apparatus for sealing an electrical component in a housing surrounding the component employs a system of capillary channels in the housing through which sealing resin is conducted from a dispensing point to completely close and seal any housing gaps. A reliable sealing and closing of different housing joints is achieved by connecting only those housing joints of identical or similar capillary characteristics to a particular dispensing point via channels. A number of different dispensing points each associated with a particular group of housing gaps to be sealed are thus provided and different resins or variations of a same resin may be individually supplied to each dispensing point. The dispensing points and associated capillary channels may be contoured and profiled in order to best facilitate resin flow therein in order to insure a complete sealing of the housing.
