How Does a Pogo Pin Work?
The spring Pogo Pin is a precision connector used in electronic products such as mobile phones. The spring probe usually includes a needle shaft, a needle tube, and a spring. The spring is arranged in the Pogo Pin tube, and the needle shaft is inserted into the needle tube. When the needle shaft is squeezed by the component, the spring is compressed and moves axially, the outer surface of the needle shaft contacts the inner surface of the needle tube, and the electrical signal is transmitted from the needle shaft to the needle tube.
Spring probes are generally used in precision connections in electronic products such as mobile phones, communications, automobiles, smart wearables, drones, smart robots, aerospace, and other electronic products, which can improve the corrosion resistance, stability, and durability of these connectors.
The spring probe is a carrier for transmitting signals and currents, and it is the hardware that realizes electricity or conduction. Most of the spring probe needles are in contact with the copper wall obliquely downward. The spring of the spring probe bears a small amount of gravity, so it is required to The inner wall of the copper sleeve be smooth.
With the popularization of electronic equipment, the application of spring probes is becoming more and more extensive. It is widely used for signal transmission. The most common one is the antenna thimble of mobile phone; the advantage of using spring probe antenna and motherboard is that the inductance is small, Weak interference to RF signals
