Ambient temperature and humidity are important factors affecting the reliability of electronic connectors. Through a series of chemical reactions, it can easily lead to contact failure and insulation failure, which ultimately reduces the service life of the connector and causes frequent equipment failures.
The reason why the ambient temperature and humidity is easy to cause contact failure is that the contact material of the connector is generally copper metal, and copper will undergo an oxidation reaction under the action of ambient temperature stress to form an oxide film. As the oxide film grows and thickens, due to the poor conductivity of the oxide film itself, the thickened film increases the contact resistance of the contact body, which eventually leads to contact failure of the connector.
The insulation failure is because the connector insulator is mainly made of high molecular polymer and other materials. Under the action of temperature stress, the movement of the molecules inside the polymer material will speed up, and vacancies will be generated on the molecular chain. At this time, harmful gases in the air, etc. The medium will penetrate and diffuse into the material, and under the influence of the ambient temperature, the material will undergo thermal degradation and cross-linking reaction, the material will deteriorate, and the physical and electrical properties of the material will be reduced, resulting in a reduction in the insulating properties of the insulator. lead to the failure of the connector insulation.
Therefore, in order to maintain the long-term reliability of the connector, the connector manufacturer must consider the selection and processing technology of the contact material and insulating material of the connector.
