Spring probe.The role of the copper pillar of the Pogo Pin spring ejector

　　The copper pillar of the Pogo Pin spring ejector is a key component of the Pogo Pin connector, and it mainly plays the following roles:

　　1. Conductive function: The copper pillar is a conductor responsible for establishing a stable electrical connection when the Pogo Pin is inserted into the target jack. It is usually plated with precious metals (such as gold, silver, etc.) to improve conductivity and anti-oxidation ability.

　　2. Support function: The copper pillar provides structural support for the spring, so that the spring can remain stable during compression and recovery, ensuring that the Pogo Pin maintains good contact performance during multiple plugging and unplugging.

　　3. Heat dissipation function: The copper pillar has good thermal conductivity, which can help the Pogo Pin quickly dissipate heat under high current working conditions, prevent overheating, and thus improve the service life and reliability of the connector.

　　4. Mechanical strength: The hardness and toughness of the copper pillar enable it to maintain its shape when subjected to external forces, preventing the Pogo Pin from deforming or breaking during use.

　　From the above points, it can be seen that the copper column plays a vital role in the Pogo Pin spring ejector, ensuring the stability and reliability of the connector in various application environments.
