A basic spring-loaded pin consists of 3 main parts: a plunger, barrel, and spring. When force is applied to the pin, the spring is compressed and the plunger moves inside the barrel. The shape of the barrel retains the plunger, stopping the spring from pushing it out when the pin is not locked in place.

In the design of electrical contacts, a certain amount of friction is required to hold a connector in place and retain the contact finish. However, high friction is undesirable because it increases stress and wear on the contact springs and housings. Thus, a precise normal force, typically around 1 newton, is required to generate this friction. Since a spring-loaded pin needs to have a slight gap between the plunger and barrel so that it can slide easily, momentary disconnections can happen when there is vibration or movement. In order to counter this, the plunger usually has a small tilt to ensure a continuous connection.

What is Pogo pin?

Pogo Pin is spring loaded probe which is made by precision instruments with riveting workmanship. It usually consists of plunger, tube and spring.

Pogo pin is generally applied in the precision connection inside the electronics products such as mobile phones, communication devices, automotive, medical devices, aerospace devices and so on. Since pogo pin is very fine probe, it can make the finished connector light in weight, small in size and exquisite in look when it’s applied in a precision connector.
