The application of pogo pin charging contacts on Bluetooth headsets

The prosperity of smartphones has also promoted the rise of smart wearable devices; smart bracelets, smartwatches, Bluetooth headsets, and so on. So what are the precautions for the application of the pogo pin charging contact on the Bluetooth headset?

First of all, the application of small size (limited space):
The exquisite compactness of wearable devices has been particularly well-interpreted on Bluetooth headsets. It is necessary to use the smallest size to achieve powerful functions, which is a test of the designability of product engineers. Therefore, the pogo pin charging thimble contact used on the Bluetooth headset requires a particularly small volume and also requires a large current to be carried.
Second, anti-oxidation and corrosion:
Sports enthusiasts particularly like to listen to music while exercising. Human sweat is corrosive. This requires that the charging contacts of Bluetooth headsets must be anti-oxidation and corrosion to ensure that the pogo pin charging contacts are not corroded by human sweat. The use of the headset will not have any effect.
Third, make it waterproof:
Some people may be swimming while listening to songs. At this time, the Bluetooth headset is required to be waterproof, and the charging contacts are the point that connects to the outside world. The process requires good waterproof treatment, at least IP67 standards.
