Pogo pins are an indispensable part of electronic equipment. Observing along the path of current flow, you will always find one or more pogo pins. In our lives, pogo pins are generally used for precision connections in electronic products such as mobile phones, communications, automobiles, smart wearables, drones, smart robots, aerospace, etc., which can improve the corrosion resistance, stability, and durability of these connectors . The role of the pogo pin can not be ignored.
First, it helps to improve the production process. Its appearance simplifies the assembly process of electronic products and simplifies the mass production process. Secondly, it is easier to repair. If an electronic component fails, the failed component can be quickly replaced when the pogo pin is installed; at the same time, the pogo pin is easy to upgrade, and the use of the pogo pin can increase the diversity and flexibility of the design. You cannot live without electricity, so you cannot live without a pogo pin. Pogo pins are also called Pogo Pins, pogo pins, thimble pins, pins, and probes in China. They generally refer to Pogo Pin pogo pins, that is, connecting two devices with components to transmit current or signals.
The pogo pin pins were never designed to have high-speed data transmission. Let's take a look at the working principle of pogo pins. The mating ends of the contact points are usually gold-plated and are usually sharp points. The connection is made when the sharp point is pressed against the normally soft "mating contact". Since there is no wiping action, like a standard pin and socket contact, this design is more susceptible to contamination and corrosion, increasing the contact resistance through the connection, which makes low-voltage, high-speed signals more difficult to transmit.
The second design issue is the internal spring of the pogo pin. The spring must make good contact with the plunger and base of the pogo pin, otherwise problems will occur. Due to its spiral design, the spring also introduces inductance into the contacts. In order to overcome the problem of using these contacts in a matched impedance system, each signal circuit must be surrounded by several grounding circuits to isolate the signal path of the contacts from the surrounding signal paths.
