Advantages and disadvantages of the internal structure of the pogo pin:

1. Pogopin pogo pin anti-drilling structure

Advantages: smooth compression, easy processing, large stroke, conventionally used for signal transmission

Disadvantages: The impedance is unstable and requires a large amount of elasticity. It is widely used for charging and signal transmission of smart wearable products.

2. Pogopin pogo pin beveled edge structure

Pros: Impedance stable at 20-50 milliohms

Disadvantage: It is not easy to process compared to the reverse drilling structure. Can pass 2-3A current

3. Pogopin pogo pin section bevel and ball structure

Advantages: stable impedance, can increase the ball of excessive current

Disadvantages: The process is more complicated than the beveled edge structure, and there are certain requirements for the height of the needle tube

4. Pogopin pogo pin bevel with retaining wall and ball structure

Advantages: high current resistance, stable structure

Disadvantages: Needle increases retaining wall, complex process, high cost

5. Pogopin pogo pin ball needle structure

Advantages: It can be used for mechanical positioning and lateral connection for signal transmission.

Disadvantages: mainly need to bear lateral force, the size of the product used is limited by the size of the ball, and cannot pass more than 1A current, etc.
