Pogo pin is composed of pin shaft, springs, the needle of three basic parts formed by precision instruments riveting pressure after the preloading of spring-loaded probes, the interior has a sophisticated spring design.Gold-plated pogo pin surface finishes are generally better able to improve its corrosion resistance function, mechanical properties, electrical properties, etc.Pogo pin is generally used in mobile phones, communications, automotive, medical, aerospace and other electronic products in the precision connection, can improve the anticorrosive property of these connectors, stability and durability.Due to the pogo pin is a very fine probe, so used in precision connector can reduce the weight of the connector and the volume of the appearance, can let the connector more delicate and beautiful.
