Seal apparatus and method of manufacturing the same
A seal includes a housing with an exterior surface. The housing forms a cavity extending from the exterior surface into the housing and defines at least one slanted interior surface. The at least one slanted interior surface extends from the exterior surface of the housing and is in a substantially non-perpendicular and angled relation to the exterior surface of the housing. The seal also includes at least one electrical lead that extends through the housing and has a portion exposed across the cavity therein. The at least one electrical lead extends from the housing and is configured to be in electrical contact with at least one electrical component encased within the electronic control housing. The seal also includes an adhesive material that substantially fills the cavity and surrounds the exposed portion of the at least one electrical lead exposed across the cavity.
1. A method of manufacturing a seal comprising:
forming at least one electrical lead;
molding a housing at least partially around the at least one electrical lead, the housing formed with an exterior surface;
forming a cavity in the housing, the cavity extending into the housing from the exterior surface, wherein the cavity defines at least one slanted interior surface, the at least one slanted interior surface extending from the exterior surface and being in a substantially non-perpendicular and angled relation to the exterior surface, the cavity formed so as to expose a portion of the at least one electrical lead across the cavity; and
filling the cavity with an adhesive material, the adhesive material substantially filling the cavity and surrounding the exposed portion of the at least one electrical lead.
2. The method of claim 1 further comprising curing the adhesive material.
3. The method of claim 1 wherein forming the cavity further comprises forming the cavity so as to extend completely through the housing.
4. The method of claim 3 further comprising placing a block beneath the housing before filling the cavity.
5. The method of claim 1 wherein the at least one slanted surface of the cavity of the seal comprises a plurality of individual step portions.
6. The method of claim 1 wherein the at least one slanted surface of the cavity of the seal is formed with a wave-like pattern.
