Use Case of High Current Pogo Pins

Our R&D Team Who Focused on The Product

After receiving customers’ requirements, we studied the product requirements together. we were sure we could do it based on our R&D experience, furtherly, we worked out DFM & DFMEA to confirm every detail no risks on process manufacturing and technological process, including preliminary quality SIP and process SOP, and so on. Finally, a high current pogo pin with coaxial integration was commended.

What is The Structure of High Current Pogo Pins?

It has a different structure from other pogo pins. The usual three parts of the pogo pin do not meet the requirements for high current use, its structure is not enough to support the passage of high current, easy to form a short circuit.

Read More

So, high current pogo pin often adopts the structure of four parts type or coaxial integration. The high current pogo pin’s special structure is mainly to make the current distribution of the internal circuit so that the maximum current can be divided and distributed to different parts of the internal circuit.

High current pogo pin-Coaxial integration type

What is Its Structure of Coaxial Integration?

Coaxial integrated structure: The plunger part of the pogo pin is a structure through spring and needle pipe. It keeps the simple structure of the pogo pin and effectively reduces the resistance.

The pogo pin with this structure is widely used in high-speed and high-current applications. The advantage of this structure is the easy formation of short circuits, so it is the most suitable for the low-resistance application. The disadvantage of this structure is that the length of the pogo pin is fixed and needs a certain activity space.

High current Pogo Pin - T-pin Type

T-pin type design: The T-pin structure adds a cover between the plunger and the spring,

which contacts the barrel to form a current-dividing circuit. The high current pogo pin with a T-pin type design has a wider range of applications and surface area, as well as a simple structure and low resistance. The disadvantage of this structure is the complicated mechanism and high cost. The t-pin structure is widely used in pogo pins.

High current pogo pin - Ball Type

Ball-type design: The ball structure adds a ball between the plunger and the spring,

What is advantage of High Current Pogo Pin

What are The Advantage of High Current Pogo Pins?

Stable contact resistance: It is mainly used in the intelligent terminal equipment, so it has high requirements for the stability of the current signal.Life cycle: It needs to be inserted and removed repeatedly during operation, and its life cycle can reach 100,000 times.

Small size, high density, lightweight: With the continuous development of science and technology, intelligent equipment tends to be miniaturized and diversified. Therefore high current pogo pin size and accuracy requirements are particularly high.Easy to update: With the continuous progress of technology, it can also update its components when installing a high current pogo pin. At the same time, better components can be used to replace them.
