With the introduction of Apple's wireless charging mobile phones, wireless charging technology has developed rapidly. After removing the data cable, the wireless charger has the advantages of safety, reliability, convenience, and speed.
A wireless charger is a device for charging according to the principle of electromagnetic induction. Its principle is similar to that of a transformer. A coil is installed at the transmitting end and the receiving end, so that the transmitting coil sends an electromagnetic signal to the outside world based on electromagnetic induction. Then the electromagnetic signal is converted into electric current to realize the purpose of wireless charging.
The data cable suitable for the wireless charger should be easy to move and connect, and can supply power at the same time. Therefore, the core of the contact surface magnetic connector that determines whether the wireless charger can work normally is the POGO PIN connector, which has the following advantages:
1. The internal structure adopts nozzle claw design. When the needle is stretched or shortened, the current and voltage will not be cut off instantly, and the contact resistance is very small. Therefore, the heat of the connector is very low.
2. Anti-amplitude, anti-shock and anti-compression.
3. The magnetic connector of the spring thimble can be flexibly connected to wireless charging and can be automatically calibrated and docked.
4. It meets the requirements of plug-in resistance and has a long service life, which can meet the use of magnetic connectors for 5 years.
