Pogo Pins are small electrical contact pins with an internal spring mechanism designed to ensure reliable electrical contact. They are one of the most commonly used types of spring connectors, widely adopted across various electronic and industrial applications. Pogo pins play a critical role in the wiring harness industry by providing highly reliable, vibration-resistant electrical connections, especially suited for applications requiring frequent mating cycles and limited space.

The main components of Pogo Pins include:

• Plunger/Tip: Responsible for contacting the mating surface and conducting current. Typically gold-plated or made from other wear-resistant materials to ensure excellent conductivity and corrosion resistance.
• Spring: Located inside the pin core, it provides stable spring force to maintain consistent and uniform contact pressure against the mating surface, ensuring a reliable connection.
• Barrel/Shell: Encases the plunger and spring, guiding the plunger’s movement and protecting the internal structure, while also serving as part of the electrical contact.
• Tail: Used to connect to PCBs or wiring harnesses, available in various forms such as solder pads, pins, or crimp terminals.

Common types of Pogo Pins:

• Standard Pogo Pins: Suitable for most testing and connection scenarios.
• Long Stroke Pogo Pins: Support larger compression travel, ideal for applications with greater mating tolerances.
• Micro Pogo Pins: Compact size, designed for precision electronics and consumer products.
• Spring Leaf Pogo Pins: Feature a spring leaf design to enhance elasticity and durability.
• High Current Pogo Pins: Designed for high current transmission with specially engineered pin bodies and springs.

Typical applications of Pogo Pins:

• Circuit Board Testing: Used as ICT (In-Circuit Test) probes on smartphone mainboards for rapid electrical testing of chips and circuits. For example, on the Apple iPhone production line, pogo pins test various electrical nodes on the motherboard.
• Charging Interfaces: Serve as wireless charging contact points in smartwatches (e.g., Apple Watch) and wireless earbuds (e.g., AirPods), ensuring stable charging.
• Electronic Module Connections: Provide flexible connections between smartphone camera modules and mainboards, maintaining stable signal transmission while allowing slight movement.
• Automation Equipment: Electrical connections between robot end-effectors and control systems, supporting frequent mating and vibration environments.
• Medical Devices: Connect sensors and main control boards inside wearable heart rate monitors, guaranteeing precise and reliable signals.
