When designing a short and small Pogo pin (spring thimble), it is necessary to take into account its structural characteristics, functional requirements, and space constraints. Here are some design points and suggestions:
First, structural characteristics
Needle design:
Beveled needle: In order to ensure 100% contact with the needle tube at work, the end of the needle and the spring can be designed as a beveled surface. This design helps to reduce contact impedance and ensure stable conduction.
Anti-drilling needle: For space constraints, the anti-drilling design can be used, so that the spring length can exceed the length of the needle, so as to obtain stable elasticity and travel. This design is particularly suitable for small size Pogo pins.
Needle and spring:
The needle tube should be designed to be strong enough to support the repeated movement of the needle and spring while maintaining adequate electrical conductivity.
The selection of the spring should take into account its elasticity, travel and durability to ensure that the Pogo pin will work properly under various conditions of use.
Second, functional requirements
Electrical conductivity: Ensure that the Pogo pin conducts electricity well to reduce signal attenuation and energy loss.
Stability: Under multiple insertions and vibration environments, the Pogo pin should be able to maintain a stable connection without loosening or falling off.
Durability: Considering that Pogo pin may need to work in harsh environments, its material and structure should have good durability and corrosion resistance.
3. Space limitation
Compact design: In order to meet the short and small requirements, the various components of the Pogo pin need to be compact design to reduce unnecessary space occupation.
Optimized layout: By optimizing the layout of needles, tubes and springs, you can achieve the best performance and stability in limited Spaces.
4. Design suggestions
Select the right material: Select the right material according to the use environment and functional requirements, such as stainless steel, copper alloy, etc., to improve the electrical conductivity, durability and corrosion resistance of Pogo pin.
Precision machining: Precision machining equipment and processes are used to ensure precise dimensions and smooth surfaces of each component of the Pogo pin to reduce contact resistance and improve connection stability.
Strict testing: After the design is completed, strict performance testing and reliability testing are carried out to ensure that the Pogo pin meets the design requirements and use standards.
To sum up, the design of short and small Pogo pin needs to consider many aspects such as structural characteristics, functional requirements and space constraints. Through reasonable design and processing, Pogo pin products with high performance, high stability and long life can be achieved.
