Application of pogo pin connector on the wireless charger
With the release of wireless charging mobile phones by Apple, wireless charging technology has developed rapidly. Because the data cable is removed, wireless chargers have great features such as safety, reliability, convenience, and immediacy.
The 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 set at the transmitting and receiving ends. The transmitting coil sends an electromagnetic signal to the outside under the action of electric power, and the receiving coil receives the electromagnetic signal. Signal, and then convert the electromagnetic signal into electric current, and then realize the purpose of wireless charging.
The data cable that matches the wireless charger requires that it is easy to move, plug, and supply power at the same time. In the number of plugs, the most important thing is the connectivity of the contact surface, which determines whether the wireless charger can work normally. Therefore, the core of the magnetic connector is the POGO PIN connector, which has the following advantages:
1. The internal structure uses a spring claw design. When the needle is stretched and contracted, it will not cause instantaneous interruption of current and voltage, and the contact resistance is very small. Therefore, the heat generation of the connector is very low.
2. Excellent seismic performance, impact resistance, and compression resistance.
3. Flexible connection can be made between the magnetic connector of the spring thimble and the wireless charging, and the docking can be automatically calibrated.
4. It meets the plug-in resistance requirements, has a long service life, and can meet the use of magnetic connectors for 5 years.
