Problems solved by technology

However, this conventional configuration still has the disadvantage that external fluid or moisture at the relay base 130 may create a short circuit path between the relay terminals 130 and thus cause malfunctioning of the sealed relay 100
[0007] However, while the above configurations are effective in improving the protection of components inside the enclosure from fluid or moisture penetration, they are not effective in protecting the electrical terminals outside the enclosure Protected from moisture or condensation
As a result, the corresponding sealed relays cannot be installed in any orientation without risking a short circuit between the terminals

Abstract

The present invention relates to a seal housing for an electrical device, such as an electromagnetic relay, and a sealed relay using the seal housing. A seal housing comprises a base, a cover adaptedto cover an inwardly facing side of the base, thereby forming a housing for accommodating components of the electrical device, and a sealing plate adapted to partially cover an outwardly facing side of the base and protect the base from fluid condensate. 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 sealingplate, so that device failure due to short-circuits between terminals protruding from the base can be prevented. The intersection regions between the base, the cover and / or the electrical terminals are sealed by applying a sealing compound over discrete regions along the intersections regions that are not covered by the sealing plate, thereby reducing the amount of sealing compound required.

Description

technical field [0001] The present invention relates generally to sealed housings for electrical devices and sealed electrical devices, such as electromagnetic relays and the like, which use sealed housings to protect components of the electrical device from fluids such as water and dew condensate, and more particularly, It relates to a sealed enclosure having a sealed base that protects any terminals of an electrical device protruding from the base from short circuits caused by condensation condensation and is used to seal all installation orientations of the electrical device. Background technique [0002] Electrical devices, such as electromagnetic relays, having a hermetically sealed, fluid-tight enclosure to protect components of electrical devices from the penetration of fluid, moisture and / or condensation condensation, which are frequently used in applications where water condensation may occur or icing applications. This can occur, for example, when electrical insta...
