In recent years, with the continuous development of electronic products, many devices have been born that use contact type connections, namely pogopin charging docks. This design is very convenient for charging, and only requires rough alignment to achieve connection. Unlike USB ports, which require careful alignment to ensure charging, contact type connections only require rough alignment and can usually be directly connected through structural or magnetic design.

Compared with plug-in connectors, contact type and plug-in type connectors also have a much longer lifespan. Each connection is only a top surface contact and is not prone to friction. Therefore, the service life of pogopin charging sockets can usually easily reach tens of thousands of times. Some specially designed products can even achieve hundreds of thousands of times of plugging and unplugging, and can withstand high-intensity continuous plugging and unplugging.

Pogopin charging docks can usually be designed with electrical characteristics and structures to match the device, so reliable design is required in terms of body shape, appearance, and other aspects. At the same time, project engineers also need to cooperate. Due to the relatively small size of spring pins, they can be tightly arranged, so for electronic products, they do not occupy too much space.
