Abstract

PURPOSE:To prevent corrosion by hydrobromic gas of a contact metal by apply ing a metal more reactive on bromine than the contact metal to the contact in an electronic part, for example, a relay which contains a contact. CONSTITUTION:In order to prevent corrosion of a contact by bromine that is produced from a flame retarder of a plastic material in an electronic part, for example, a relay, which contains a contact a metal more reactive on the bromine than the contact metal is applied to the contact. By means of applying the metal more reactive on the bromine to the contact, the bromine is trapped so that the corrosion of the contact can be prevented. For example, a relay is assembled by using Au for its contact metal, which is covered with Zn or Sn. When the contact is covered with such a metal as Zn of Sn more reactive on the bromine, the failure rate of the contact can be decreased.

(Prior Art) Conventionally, electronic components including precision points (for example, relays, switches) often use plastic materials filled with brominated flame retardants. When this electronic component is used at high temperatures of 80°C or higher, hydrogen bromide gas is generated, and in this case, when the contacts are opened and closed, it reacts with the contact metal and corrodes, causing poor contact (which the invention aims to solve). The present invention was proposed in view of the above-mentioned circumstances, and its purpose is to eliminate hydrogen bromide gas when plastic materials filled with brominated flame retardants are used in electronic components containing precision contact points. An object of the present invention is to provide a structure for preventing corrosion of contacts in electronic components caused by bromine, which makes it possible to prevent corrosion of contact metals caused by bromine.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a method for preventing corrosion of contacts caused by bromine generated from flame retardants in plastic materials in electronic components including contacts such as relays. The gist of the invention is to provide a structure for preventing corrosion of contacts in electronic components by bromine, which is characterized by mounting a metal that reacts more easily with bromine than contact metals.
