  The design of the Pogo pin connector determines the actual performance of the pogo pin connector to a certain extent. Through the analysis of common parameters in pogopin connector design, we can analyze the rationality and practicality of pogopin connector design.

How to improve the production process of the spring signal pin(图1)

  Low level circuit contact resistance

  When supplying voltage and current does not change the size of the physical contact surface and the oxide and film of the contact surface, evaluate the contact resistance of the contact system,

  The maximum test current is 100mA, and the maximum open circuit voltage is 20mV.

  Insulation resistance

  When the DC potential is supplied to adjacent contact points or between the metals closest to the contact points, the resistance of the insulating material is detected.

  Dielectric withstanding voltage

  The voltage that the connector can withstand when the system voltage increases suddenly or because of switching, an instantaneous excess potential is generated when the connector can remain safe and undamaged.

  Normal force

  The pressure of the contact point perpendicular to the contact surface under normal use of the contact system.

  Durability

  Because the contact surface is worn out during insertion and removal, this wear will reduce the mechanical and electrical performance of the connector. Under the set environment, the connector is inserted and removed as a cycle. The minimum number of insertion and removal cycles the connector can withstand To evaluate the durability of the connector.

  Vibration

  Assess the impact of the small changes on the contact surface caused by the mechanical force on the electrical characteristics of the contact system.

  Mechanical shock

  Detect the mechanical and electrical integrity of the connector. When the connector device acts on the electronic device, it may be subjected to vibration during handling, transportation, etc.

  Thermal shock

  Detect the resistance when the connector is exposed to extremely high and low temperatures, or the worst-case shock during storage, transportation, and use.

  Temperature Life

  When exposed to a high temperature environment where the mechanical properties fail due to temperature changes, evaluate the impact of this environment on electrical stability. High temperature will cause contact oxidation and reduce the positive force of the terminal, which will reduce the electrical performance.

  Thermal cycling with humidity
