FAQ
Why is 6 pin connector more popular than traditional plug-in connector?
Longer service life, stable and reliable connection, adaptable to harsh environments, compact size for integration, and low maintenance costs. Engineers prefer 6 pin connectors because their elastic structure reduces wear and ensures stable signals with low contact resistance. It is not easy to disconnect during vibration, with good dust and water resistance, and can adapt to high-density PCB layouts. The space saving design makes this pogo pin connector the preferred choice for precision equipment.
What is 6 pin connector working principle?
The spring pushes the plug tip, providing constant pressure to ensure stable contact, unobstructed signal flow, and efficient current transfer. The plunger tip tightly adheres to the contact surface under the action of the spring, ensuring stable conductivity. Not affected by external forces, the spring pre tension maintains contact and reduces resistance fluctuations. The signal quality of the 6 pin connector doesn’t get worse yet after prolonged use.
Why is 6 pin design more common than 4-pin or 8-pin?
Reasonable signal and power distribution, compact structure to meet most needs. The 6 pin connector can balance cost and performance, with better stability than 4-pin and lower complexity than 8-pin. 6 pogo pins can simultaneously transmit power and signals, suitable for multiple applications, it is just right. It can avoid unnecessary pins increasing costs while ensuring conflict free data and power transfer, making it a common standard.
How does 6 pin connector prevent current overload?
Control spring pressure, select appropriate electroplating layer, optimize contact area, ensure good heat dissipation, and avoid overcurrent damage. Excessive contact resistance can cause heating, therefore precise control of spring pressure is required to stabilize the contact. Reasonable selection of coating can reduce losses, increase contact area, and reduce resistance. The heat dissipation design ensures that there is no temperature rise when high current passes through, ensuring the stable operation of 6 pin connector.
What will affect life cycles of 6 pin connector?
Spring fatigue, contact surface oxidation, external force damage, temperature and humidity changes, and high current load. After prolonged use, the spring may lose its elasticity, and the metal surface exposed to air will oxidize and affect conductivity. Excessive external force may cause deformation of plunger tip, and extreme temperature and humidity may accelerate the aging of 6 pin connector. High current loads can cause overheating and also reduce the lifespan of 6 pin connector.
Why is gold generally used for plating or coating of 6 pin connector?
Gold is resistant to oxidation, has good conductivity, strong corrosion resistance, low friction loss, and maintains long-term stable connection. Compared to other metals, gold is not easily oxidized, has low signal transfer loss, and can withstand harsh environments. The service life far exceeds that of nickel or silver plating, and high-frequency contact will not affect contact performance due to wear. The 6 pin connector with gold-plated pogo pins is the best choice for high-precision connectors.
