Spring Loaded Solder Cup Pin Catalog

Solder cup pogo pin, also known as spring loaded solder cup pins, solder cup spring contacts, or through hole spring loaded solder cup pins, are primarily used to establish reliable electrical or signal connections between components. They ensure consistent conductivity and stable contact performance in various electronic applications.

Solder Cup Pogo Pins Overview

Solder Cup Pogopin Product Details

With advanced technology and expert craftsmanship, we create durable, high performance custom solder cup pogo pin / solder cup spring connector pin tailored to each project’s needs. 

What is solder cup pogo pin

Solder cup pogo pin is a type of spring loaded electrical contact designed for reliable temporary connections in electronic devices. Unlike surface mount or through hole pogo pins, it features a small hollow cup at the tail end where a wire can be inserted and soldered directly. This makes wiring easier, stronger, and more flexible, especially in low to medium volume assemblies or prototypes. The pogo pin’s internal spring allows it to maintain stable electrical contact despite vibration, tolerance variations, or repeated mating cycles. Solder cup pogo pins are widely used in test fixtures, battery connections, charging docks, and modular connectors. They are valued for quick assembly, good conductivity, mechanical durability, and ease of repair or replacement without redesigning a PCB.

How to install solder cup pogo pin

To install solder cup pogo pin, first prepare the wire by stripping a small section of insulation and twisting the strands neatly. Tin the exposed wire and the solder cup with a small amount of solder to improve bonding. Insert the tinned wire into the solder cup, ensuring it sits fully inside. Heat the cup gently with a soldering iron until the solder flows and securely joins the wire and pin. Avoid overheating, as excessive heat may damage the internal spring. Allow the joint to cool naturally without movement. After cooling, inspect the joint for a smooth, shiny finish. Finally, perform a gentle pull test and check electrical continuity to ensure a reliable connection.

solder cup pogopin material & parts

Solder cup pogo pin is made of several key materials and parts that ensure reliable electrical and mechanical performance. The main body, or barrel, is typically made from brass or phosphor bronze for strength and conductivity, often plated with nickel and gold to resist corrosion. Inside the barrel is a spring, usually stainless steel or music wire, which provides consistent contact force. The plunger (or pin head) is commonly brass or beryllium copper, also gold plated to improve wear resistance and signal stability. At the rear is the solder cup, formed as part of the barrel, designed to hold solder and wire securely. Together, these parts allow repeated compression, stable contact, and durable wire termination.

solder cup pogopin Internal structures

Solder cup pogo pins commonly adopt a plunger bevel structure combined with a plunger inner hole bevel structure to ensure smooth travel and stable contact. The matched bevel surfaces guide the plunger inside the barrel, helping reduce sticking and improving alignment during repeated compression. When lateral force occurs, the bevel design helps convert it into effective contact force, maintaining reliable electrical performance. An internal spring provides consistent pressure, compensating for tolerance and vibration in high cycle applications. The solder cup termination offers a secure wire soldering cavity for strong mechanical retention and low resistance conduction. With gold plated contact surfaces, these pins achieve low contact resistance, corrosion protection, and long service life.

How Solder Cup Pogo Pins Work

Solder cup pogo pins work by combining a soldered wire termination with a spring loaded contact tip. First, a wire is soldered into the cup shaped tail to form a strong, low resistance connection. Inside the pin, a plunger slides within a barrel under spring force. When the tip meets a pad or terminal, it compresses and maintains constant pressure, ensuring reliable electrical contact even with vibration or tolerance variation. The guided plunger design helps keep movement smooth and reduces the risk of sticking during high cycle use. Gold plated contact areas lower contact resistance and resist oxidation, supporting stable signal or power transfer.

Dip Pogo Pin Contact Resistance

This chart illustrates that during the full compression and release stroke of the dip pogo pin, the spring force increases smoothly while the contact resistance remains extremely low and stable. This demonstrates a well-engineered internal structure, precise machining tolerances, and high-quality vacuum blind-hole plating that together ensure reliable electrical connectivity and long-term performance stability.
