Do you know what factors will affect the life of the circular connector jack?
Circular connectors are used in complex environments. In order to ensure stable performance under different environmental conditions, the requirements for environmental adaptability are relatively high. However, even if the circular connector has strong environmental adaptability, in the long-term use process In China, the influence of environmental factors on the circular connector cannot be ignored, especially the socket part is susceptible to environmental factors such as humidity, temperature, vibration, etc., thereby shortening its service life.

Circular connectors are used in complex environments. In order to ensure stable performance under different environmental conditions, the requirements for environmental adaptability are relatively high. However, even if the circular connector has strong environmental adaptability, in the long-term use process In China, the influence of environmental factors on the circular connector cannot be ignored, especially the socket part is susceptible to environmental factors such as humidity, temperature, vibration, etc., thereby shortening its service life.
1. Humidity: When the humidity in the environment is too high, the water and metal parts will be corroded this year, the insulation of the electronic socket will be reduced, the conductivity will increase, the higher the humidity in the environment, the month will affect the service life of the circular connector jack, Many products are now made of materials that are less affected by water.
2. Temperature: Different seasons have different temperatures, especially in summer. The ambient temperature is high, and there is current after plugging in, which will increase heat, causing the jack temperature to rise easily. High temperature will change the service life of the circular connector jack. Generally, the working temperature of the circular connector jack is -60°C-200°C.
3. Salt spray: It is found that when the temperature is 35°C and the concentration of salt solution is 3%, the metal parts will be corroded, and once the metal part of the circular connector socket is corroded, the performance will be reduced.
In addition, vibration and shock will also affect the service life of the circular connector socket. When there is vibration and shock in the use environment, the connection firmness of the circular connector will be affected. Therefore, in order to extend the service life of the product, the manufacturer will pass the vibration and shock environment test before leaving the factory.
How does the circular connector plug and unplug 500 times?
Many circular connector packages on the market will indicate that the number of plugs and unplugs is 500 times, so do you know how to plug and unplug 500 times?
This needs to involve its contact resistance. Usually, the contact resistance consists of three parts, namely, conductor resistance, shrinkage resistance and film resistance. Generally speaking, the resistance value of conductor resistance is relatively small and can usually be ignored. Therefore, the data of shrinkage resistance and film resistance will be calculated in actual calculation.
From the experimental results, the contact resistance change of the circular connector is relatively stable when the number of plugging times is less than 500, but when the number of plugging times exceeds 500, the resistance value of the contact resistance increases continuously, especially when the number of plugging times reaches 2000, the ink layer on the contact surface will not be damaged when the number of plugging times is less than 500, but the base metal and gold plating layer on the contact surface will not start to wear, and the resistance of the film will remain in a stable state.
After 500 times of plugging and unplugging, the coating and matrix on the surface of the contact member begin to wear, and the contact point decreases. In addition, after multiple plugging and unplugging, the elasticity of the crown spring contact ring also decreases, increasing the contact resistance.
The above is the content of the editor's explanation. I hope it can help you. Thank you for watching. I'll see you next time.
