A pogo pin is a spring probe made of a spring, a needle shaft, and a needle tube that have been riveted together and preloaded by a precision tool. Almost every pogo pin has a gold plating on its surface, which helps it resist corrosion, work better mechanically, and conduct electricity. A pogo connector is made up of a pogo pin, various numbers of pins, and housings. Pogo Pins are the strongest type of connector.
Spring connectors are quite durable as compared to other connectors. Pogo pins are compressed vertically, which is different from any other type of connector. All of the parts are compressed in the same direction, which greatly reduces wear on each part. The problem is that when a connector is put in, two pieces of metal scratch against each other.
Over time, this will cause the outer plating to wear down, which will lower the carrying capacity. This effect is stronger when the connector is plugged in with more force. However, this can’t happen with pogo pins because the only frictional parts are the plunger and the barrel. This friction comes from the internal spring force, which is set to a certain level by the engineer.
High Tolerance Connector
Pogo pin connectors have more movement than any other type of connector. This gives engineers and people who use the connector a huge amount of freedom in how they use it. Small mistakes in production can be made up for by working travel. Take the case of LG, which had (and may still have) problems with the fingerprint sensors on the back of its G6 smartphones.
Inside the phone, the connectors were small there were flat spring connectors that touched the fingerprint sensor’s contacts. on the back cover. The back cover’s plastic expanded in warm places, causing the contact pads to separate from the connectors. A connector with a longer travel, which is more forgiving of these kinds of material changes, could have been used instead, and this problem could have been avoided.
Steady Flow of Current
The last point is that the flow of the current is very stable. Pogo Pins can be made with different spring forces and designs for each person. When the spring force is increased, the plunger is pushed against the barrel inside the pin in a more stable way. This makes the conductivity better.
Different designs, like the design of the ball and CCP’s patent for a high-current pogo design, also improve the current flow. The key is to have as many points of contact as possible between the plunger and the barrel. This will reduce the chance of a temporary break. During disconnection, the whole current may flow through the spring, which can cause the spring to melt and the pin to break.
Most of the time, this improves the user experience when working with Pogo pin connectors. This is especially true when the connectors are made in such a way that they automatically fit the device.
