Abstract

PURPOSE:To improve contact reliability of a relay contact by applying coating by fluxless solder on a case end part of a resin sealing relay and on the sealed part of a base. CONSTITUTION:A case 1 and a base 2 are formed by using a resin that has heat resistance for solder coating. An electromagnetic relay 3 is housed in the case 1, and an airtight container is composed of the case 1 and the base 2. The end part of the case 1 and a sealed part 4 of the base 2 are coated by using a fluxless solder and are thus sealed. As a method of applying solder coating, by applying automatic device for solder welding of such as electronic circuit, the sealing of a resin sealing relay can be carried out with a simple process.

[Prior Art] Conventionally, electromagnetic relays using resin as the case and base material have been widely used. The case and base are hermetically sealed to isolate the relay contacts from the outside air. This prevents oxidation of the relay contacts and increases contact reliability. In such resin-sealed relays, adhesives have conventionally been used to seal the ends of the case and the base. However, the gas evaporated from this adhesive contains aromatic compounds such as toluene and styrene, which has been a factor that inhibits the contact reliability of relay contacts.

[Problems to be Solved by the Invention] As described above, there has been a problem in that the organic gas that volatilizes from the adhesive of the resin-sealed relay affects the contact reliability of the relay contacts. Therefore, it is an object of the present invention to propose a sealing method that is more reliable than adhesives without impairing the characteristics of resin-sealed relays.
