Slotted pogo pins, also called C pins, consist of rolled strips of steel, iron, aluminum, or other metals that expand when inserted. They rely on the same compression principle as coil spring pins, but have a simpler design. Instead of using a coil spring, they use a metal strip to expand and compress the inside of the insertion hole.
Pogo pin and open pin: what is the difference?
Although they are used to connect parts, spring pins are not the same as split pins. Split pins are simply metal fasteners with two long metal blocks, which deform when inserted. When the split pin is bent, it holds the components together. However, split pins usually do not return to their original shape-at least without human intervention.
Even if the width of the spring pins is larger than the width of the insertion hole, the spring pins will work because they deform and then expand. They have at least one chamber, allowing them to enter the cargo hold. Once inside, the spring pin expands, causing it to press against the inner wall of the hole. This compression will continue to occur until the spring pin reaches the same diameter as the hole.
The history of pogo pins
Pogo pins have existed for more than half a century. The world’s first coil spring was invented by German aeronautical mechanics and pilots
In 1948, HERMAN KOEHL. Since then, they have become common mechanical speeds used in heavy machinery, automobiles, airplanes and even household furniture.
