In the design of telecom relay, the choice of gold + silver alloy as the contact material is a comprehensive decision based on multiple performance considerations. This choice is not only directly related to the electrical performance and reliability of the relay, but also closely related to its shock resistance and environmental humidity adaptability.
From the perspective of electrical performance, gold and silver are both excellent conductors with extremely low resistivity and good conductivity. After alloying gold and silver, their conductive properties can be further optimized to ensure that the telecommunications relay has extremely low loss and stable electrical characteristics when transmitting signals. This is crucial to ensure the communication quality and stability of the telecommunications system.
Gold + silver alloy has excellent corrosion resistance and oxidation resistance. In a humid or corrosive environment, ordinary metal materials are prone to corrosion and oxidation, resulting in increased contact resistance and even poor contact. The gold + silver alloy can largely resist the influence of these adverse factors, keep the contact points clean and conductive, and ensure that the telecommunications relay can still work normally in harsh environments.
In terms of seismic resistance, gold + silver alloy has high hardness and toughness, and can withstand certain mechanical shock and vibration. This makes it difficult for the contact points of the telecommunications relay to deform or be damaged when subjected to external vibration or shock, thereby ensuring the reliability and durability of the relay. Especially in earthquake-prone areas or occasions that need to withstand high-frequency vibration and shock, the advantages of gold + silver alloy contact materials are more obvious.
In addition, gold + silver alloy also has good adaptability to environmental humidity. In an environment with high humidity, some metal materials are prone to electrochemical corrosion, resulting in increased contact resistance and decreased performance. However, gold + silver alloy can maintain stable contact resistance and electrical properties in a high humidity environment due to its excellent corrosion resistance. This is of great significance for ensuring the reliability and stability of telecom relay in humid environments.
The selection of gold + silver alloy as the contact material in the design of telecom relay is to take into account the requirements of electrical performance, corrosion resistance, seismic resistance and environmental humidity adaptability. This choice not only improves the performance and reliability of the relay, but also provides a strong guarantee for its stable operation in various harsh environments.
