Ordinary pogo pin is mainly composed of syringe, piston and spring. The
material of the piston head and the barrel is brass. Although it has good
conductivity, it has no elasticity. The spring material of stainless steel or
piano strings is characterized by poor conductivity and high resistance.
Generally, the current path of the ordinary pogo pin is through the friction
between the syringe and the piston to achieve current conduction, and the
friction between the syringe and the piston is related to the spring force. The
greater the elastic force, the greater the friction and the flow capacity. The
stronger. In addition, the impedance of the ordinary pogo pin is inversely
proportional to the elasticity, that is, the greater the elasticity, the greater
the friction, and the smaller the impedance, the more stable and reliable the
pogo pin, and the greater the resistance caused by friction, the greater the
resistance to the pogo pin The performance impact is also great, and its use on
the battery connector will cause the impedance to be too large and unstable,
instantaneously disconnected, and disconnected. Let’s take a look at the
difference between ordinary pogo pin and claw spring pogo pin with Tyco
Hanze.
The flow capacity of the aviation plug connector is mainly determined by
the diameter of the needle: the larger the diameter, the stronger the flow
capacity. The flow capacity of the claw spring pogo pin is also like this, 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 claw spring
pogo pin exposed by the spring 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 the same as the ordinary pogo pin battery connection machine, and
the claw spring type pogo pin with the spring exposed can be made into a thinner
battery connector.
Specifically, the difference between the claw spring type pogo pin
connector and the ordinary pogo pin connector is in the following aspects:
The high elastic claw spring of the former can ensure the reliability of
the connection under vibration and shock environment, and the hard connection of
the syringe and the piston in the latter has the risk of power failure in the
same situation.
The impedance of the former is stable and the resistance value is low,
while the impedance of the latter changes with the elastic force, and the
resistance value is relatively 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 is absorbed by the plastic case when the
battery is installed, and has no effect on the pogo pin. The oblique pressure of
the latter is absorbed by the constriction of the syringe when the electric
hammer is installed, resulting in deformation and affecting the performance of
the pogo pin.
All strokes of the former are reliable working strokes, while only the
second half of the strokes of the latter are reliable.
