Embodiment Construction

[0030] The method according to the invention can be used for different housings including housing walls in which components are guided outwards through the housing wall and the housing has to be sealed. This includes, for example, latches and electrical connectors, but can also involve securing the coil form or the base flap on the top cover. In the following description the method according to the invention will be described in more detail with reference to an electromagnetic relay.

[0031] figure 1 is an external three-dimensional view of an electrical component, here an electromagnetic relay 14 including a base plate 10 . Base plate 10 has a plurality of openings through which electrical connectors such as pins 12 may be guided, a plurality of openings 16 for receiving latches, and a plurality of openings 18 for applying encapsulant.

[0032] figure 2 Electromagnetic relay 14 is shown from below, so pin 12 , latch receiving opening 16 and opening 18 can be seen.

Abstract

The invention discloses a method of sealing a housing for an electrical connector (12), wherein the housing has at least one housing wall including at least one opening. To seal the opening, the method includes applying a sealant in such a way that the sealant reaches the opening along the inside of the housing wall to seal the opening. The invention also discloses an electrical component comprising a housing portion.

Description

technical field [0001] The invention relates to a method for sealing housings of electrical components. Background technique [0002] When producing microswitches for use on vehicles, it is necessary, for example, to glue the housing to the base and at the same time seal the connection pins. [0003] The housing components and connections protruding therefrom are sealed with a sealant. The housing parts may be caps and headers; the connectors may be electrical connection pins. [0004] In this method, a meniscus is formed at the interface of the components due to capillary action. When a certain amount of sealant is measured and applied to the outside of the housing, the meniscus is larger because the sealant forming the meniscus at the top itself initially has the smallest height. If the sealant is applied in close proximity to the interface to be sealed, the height of the meniscus increases due to separation drops. [0005] The formation of a meniscus can cause problem...
