Four Structural Designs of Pogo Pins
The advantage of pogo pin is to help product engineers solve internal connection problems of products. In addition, micro-miniature pogo pin has significant advantages in structural space application, assembly cost, application life, sample cycle, and cost. For example, pogo pin has four structural designs and six pogo pin types.
- Inclined structure
To ensure that the needle shaft is in 100% contact with the needle tube during operation, we cut the end of the needle shaft in contact with the spring into a slope. This design concept can ensure stable low impedance.
Product advantages: The resistance value is small and stable, ensuring close contact between the needle shaft and the tube wall and reducing the probability of instantaneous power failure.
- Bevel plus ball structure
Steel balls or insulating balls are added to the needle tube to make contact more stable, thereby reducing the current passing through the spring. In addition, the steel balls in the pogo pin have a more stable contact, so the electrical performance will improve.
Product advantages: Large passing current, small contact resistance, and stable performance.
- Double contact structure
This design is the best choice for connectors with high concentricity requirements because the spring of this design can be directly sleeved on the tapered tail pin of the needle shaft so that the needle shaft is vertically stressed, so the deflection of the shaft is relatively small.
The bottom of the needle shaft is cone-shaped, and the cone tail is placed in the spring to reduce the needle shaft's chance of shaking.
- Anti-drilled structure
This design is the best choice for small-sized connectors. It can meet the elastic demand of customers in small sizes because the length of the spring in this design can exceed the length of the needle tube. In some cases where space is limited, we put The interior of the needle shaft is hollowed out to obtain more spring assembly space, so stable spring force and relatively more compression strokes can be obtained for customers to choose from.
