Seal housing for an electrical device and sealed relay using the seal housing

An electromagnetic relay, comprising:

• an electrical terminal coupled to a relay assembly;
• and
• a seal housing including a base, a cover adapted to cover an inwardly facing side of the base to form a closed chamber for accommodating components of the relay assembly, and a sealing plate adapted to partially cover an outwardly facing side of the base, the sealing plate has an outward side with a profile that is shaped to divert fluid or fluid condensate formed at the outward side of the sealing plate, the sealing plate has an aperture through which the electrical terminal protrudes to an outside of the seal housing, the aperture surrounds the electrical terminal and is separated from the electrical terminal that extends through the aperture by a separation gap, the aperture is open into an evacuation channel provided on the base, the cover includes a slot along the evacuation channel to expel the fluid condensate accumulated at the evacuation channel from the base.

A sealing plate for protecting a base of an electrical device housing from fluid condensate, comprising:

• a plurality of apertures extending through the sealing plate and through which a plurality of electrical terminals of an electrical component extend, each of the apertures surrounds one of the electrical terminals and is separated from the electrical terminal that extends through the aperture by a separation gap, at least one of the plurality of apertures is a closed aperture that forms a closed fluid reservoir around the electrical terminal;
• and
• an outward side having an inclined face that is inclined with respect to a side of the base on which the sealing plate is mounted so that fluid condensate descends along the inclined face.
