How to design pogo pin spring ?
A lot of people think Pogo pin of the spring is a very simple components, but in use process, it is not easy, it plays a quite important role, in many people's impression, it is only comprised of several circles, and there is nothing special about, so, today we will talk about Pogopin spring is to use what equipment production, How is it produced? How should it be designed?
Pogo pin springs are usually thick in the middle and small at both ends, which is the most common. Generally, Pogo Pin spring is produced by compression Spring machine. The advantage of Pogo Pin
spring produced by Compression Spring machine is that the production speed is very fast. Therefore, in the design, if the cost is concerned, This design can be considered.
1. Design of effective winding number of Pogo PIN spring.
Because Pogo pin springs are generally small, so in the design, in order to effectively control the size of the force, then the number of turns of the Pogo pin spring is very important, when the number of turns of the Pogo PIN spring is more, the strength will be smaller. Conversely, the fewer turns the Pogo pin springs have, the greater the force.
2.Pogo PIN spring wire diameter design.
Of course, this is relatively simple, the greater the diameter of the spring line, the greater the strength of the Pogo pin spring, the smaller the diameter of the spring line, the smaller the strength of the Pogo pin spring
3.Pogo PIN spring outer ring diameter design.
When we design Pogo PIN spring outer ring diameter, this is very important. When our spring outer diameter is larger, the strength of the spring will be smaller. On the contrary, when our spring outer diameter is smaller, the strength of the spring will be greater.
4.Pogo PIN spring material selection
Because the spring is relatively small, easy to deformation, under normal circumstances, try to avoid 2 processing, so most will choose stainless steel. If in order to achieve better results, the spring will also be gilded, some engineers will use beryllium copper material to produce, but the performance is good, but the spring life is not as good as stainless steel and spring steel, these depends on the specific design requirements.
