1. Small size (limited space) application: The exquisite compactness of the wearable device has been well explained on the Bluetooth headset. It is necessary to use the smallest size to achieve powerful functions, which greatly tests the design ability of the product engineer. Therefore, the pogopin charging thimble contact applied to the Bluetooth headset requires a very small volume and also needs to carry a larger current.
2. Anti-oxidation and corrosion: Sports enthusiasts like to listen to music while exercising. Human body sweat is corrosive. This requires the charging contacts of Bluetooth headsets to prevent oxidation and corrosion to ensure that the pogopin charging contacts are not affected by the human body. Sweat corrodes and does not affect the use of Bluetooth headsets.
3. Waterproof: When you may be swimming while listening to a song, the Bluetooth headset needs to be waterproof. The charging contact is the only point that connects to the outside world, and the process needs to be waterproof. At least the IP67 standard should be achieved.
To achieve the above-mentioned material selection and production process requirements for pogopin contacts are very high.
