The difference between ordinary pogo pin connector and claw spring type pogo pin connector

time:2021-03-13 Views:152

  The flow capacity of the aviation plug connector mainly depends on the diameter of the needle: the larger the diameter, the stronger the flow capacity, and the flow capacity of the claw spring pogo pin is the same. The current range through it is 2A~20A . Therefore, the claw spring pogo pin can fully meet the current flow requirements of 5A~8A mobile phone battery connectors. In terms of structure, the size of the claw spring pogo pin is similar to that of the ordinary pogo pin, but the diameter of the spring exposed claw spring pogo pin can be much smaller than that of the ordinary pogo pin. Therefore, the size of the claw spring type pogo pin battery connector can also be made larger and the same as the ordinary pogo pin battery and machine, and the claw spring type pogo pin with exposed spring can be used to make a thinner battery connector.

The difference between ordinary pogo pin connector and claw spring type pogo pin connector(图1)

  Specifically, the difference between the claw spring type pogo pin connector and the ordinary pogo pin connector is in the following points:

  The former highly elastic claw spring can ensure the reliability of the connection under vibration and shock environment, while the latter has the risk of power failure in the hard connection of the syringe and the piston under the same conditions.

  The impedance of the former is stable and the resistance is low, while the impedance of the latter changes with the elastic force, and the resistance is high; the direct friction between the piston and the barrel of the former has nothing to do with the elastic force of the spring, while the friction of the piston and the barrel of the latter is positively related to the spring.

  The oblique pressure of the former battery will be absorbed by the plastic case when the battery is installed and will not have any effect on the pogo pin. The latter will be absorbed by the constriction of the syringe when the electric hammer is installed, causing deformation and affecting the performance of the pogo pin.

  All the strokes of the former are reliable working strokes, while the latter is only reliable for the second half of the strokes.
