One, anti-oxidation and corrosion
Sports lovers like to listen to music while exercising. Human sweat is corrosive. It is necessary to protect the charging contacts of the Bluetooth headset from oxidation and corrosion to ensure that the pogo pin charging contacts are not corroded by human sweat and do not affect the use of the Bluetooth headset.
two. To be waterproof
You may be swimming while listening to a song. At this time, the Bluetooth headset needs to be waterproof, and the charging contacts are used as the connection point with the outside world. Technically, they need to be waterproof, at least IP67 standards.
3. Small application size (limited space)
The exquisiteness and compactness of the device has been well explained in the Bluetooth headset. The powerful function must be realized in the smallest volume, which is a great test of the design ability of the product engineer. Therefore, the pogo pin charging thimble contact applied to the Bluetooth headset requires a very small volume and the ability to generate a large current.
