Introduction to the working principle of the pogo pin.thimble Wholesale

　　The pogo pins were never designed to have high speed data transfer. Let's take a look at how a pogo pin works, the mating end of the contact is usually gold plated and is usually a pointed point. The connection is made when this sharp point is pressed against the usually softer "mating contact". Since there is no wiping action, as with standard pin and socket contacts, this design is more susceptible to contamination and corrosion, increasing the contact resistance across the connection, which makes low-voltage, high-speed signals more difficult to transmit.

　　The second design issue is the internal spring. The spring must make good contact with the plunger and base of the pogo pin, which can be problematic. Due to its helical design, the spring also introduces inductance into the contacts. Finally, to overcome the problems of using these contacts in a matched impedance system, each signal circuit must be surrounded by several ground circuits to isolate the contact's signal path from surrounding signal paths.

　　The pogo pin has long been established as a reliable and trusted technology for many applications. More recently, pogo pins have been used for more "permanent" connections in cell phones, laptops, computers, and other electronic devices. Many have relied on pogo pins for their durability, relatively small size, and their ability to absorb relatively large vertical mismatches between the connectors in which they are embedded. In a world where we want quick connections to batteries, laptop screens and I/O ports, they offer a very flexible solution.
