The Three Types of Electrical Connectors

Electrical connectors are classified into three types based on their termination ends:

  • Board-to-board connectors
  • Cable/wire-to-cable/wire connectors
  • Cable/wire-to-board connectors

What are Pogo Pins?

Pogo pins are spring-loaded contact pins used primarily in electronic test systems and to make connections between modules in electronic devices. They are named for their pogo-stick-like mechanism that allows them to compress and make contact reliably even in high-vibration environments.


Description

Pogo pins are designed with a pin head that can compress into a hollow tube, allowing for consistent electrical contact. They are used extensively in charging docks, test jigs, and in any application where easy, repeatable connection and disconnection are needed.


Types of Pogo Pins

Pogo Pin Type Diameter Spring Force Current Rating Typical Use
Standard 0.9 mm to 1.5 mm 60g to 200g Up to 3A Test jigs, charging stations
High-current 2 mm to 3 mm 100g to 300g Up to 10A Battery testers, industrial applications
High-density 0.5 mm to 0.8 mm 30g to 100g Up to 1A Data transfer in compact devices

Application Areas

Consumer Electronics: Common in charging stations and docking ports for wearables and mobile devices.

Testing and Calibration: Used in test fixtures for rapidly connecting and disconnecting boards during manufacturing tests.

Medical Devices: Employed in equipment that requires frequent disassembly for sterilization and maintenance.


Conventions

Pogo pins are preferred in scenarios where space is limited and high precision is needed. They offer excellent conductivity and durability over many cycles of compression.


Pros and Cons

Pros:

  • Provide reliable, consistent contact.
  • Allow for quick connect and disconnect.
  • Suitable for high-density applications where space is at a premium.

Cons:

  • More expensive than other types of connectors.
  • Require precise alignment to ensure good contact.
  • Prone to wear and damage if improperly used or subjected to excessive force.
