In recent years, the most popular smart wearable devices on the market are TWS Bluetooth earphones, smart wristbands, smartwatches, and other smart wearable devices.

Advantages of using PogoPin spring needle contact for charging:

1. Small footprint.

2. Charging conducts electricity quickly.

3. Cooperate with magnetic connectors for precise contact.

Taking TWS Bluetooth earphones as an example, when using the pogo pin spring pin charging contact, the following points should be noted:

1. TWS Bluetooth earphones have limited space and require the use of the smallest volume pogo pin spring needle to achieve strong conductivity, which greatly tests the drawing and design ability of factory product engineers.

Because the spring pin pogo pin charging pin contact used in Bluetooth earphones requires a very small volume and the ability to carry a large current for charging.

2. The pogo pin spring top pin, as a charging contact for TWS Bluetooth earphones, needs to have anti oxidation and corrosion resistance characteristics. Because the human body secretes a large amount of sweat that seeps into the earphones, sweat is corrosive and can affect the normal charging and use of the earphones.

3. The pogo pin spring top pin also needs to have waterproof characteristics. For example, swimming, rain, sweat, etc. can seep into the headphones. As the only point of connection between Bluetooth earphones and the outside world, the charging contact needs to be properly waterproof in terms of product technology, and at least meet the IP67 standard.
