内接点の臭素による腐食の防止構造を提供することにあ
る。(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.

を発明の要旨とするものである。(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.

ない。(Example) Next, an example of the present invention will be described. It should be noted that the embodiments are merely illustrative, and it goes without saying that various changes and improvements may be made without departing from the spirit of the present invention.
接点金属をAuにし、そのまわりをZnあるいはSnで
おおったものを使い、リレーを組み立てた。A relay was assembled using Au as the contact metal and surrounding it with Zn or Sn.
この様にして組み立てたリレー100個を作動させ、接
触抵抗を計測し、100mΩ以上を不良と判定した。そ
の結果は第1表のとおりである。100 relays assembled in this manner were operated, contact resistance was measured, and contact resistance of 100 mΩ or more was determined to be defective. The results are shown in Table 1.
第1表
(発明の効果)
叙上のように本発明によれば、接点金属のまわりに臭素
をトラップする金属を接合しておくと、はとんど臭素が
接点と反応することはなくなり、製品の品質の向上に益
することが大きい。Table 1 (Effects of the Invention) As described above, according to the present invention, if a metal that traps bromine is bonded around the contact metal, bromine will hardly react with the contact. This greatly benefits the improvement of product quality.
この結果から、接点のまわりを臭素と化合しやすい金属
Zn、 Snでおおったものを使用すれば、接点の不良
率を減少させることが判る。From this result, it can be seen that the failure rate of contacts can be reduced by using metals such as Zn and Sn, which easily combine with bromine, around the contacts.
