Principle and Structure of Pogo Pins:
| Component | Principle |
|---|---|
| Spring | Stores and releases energy between plunger and housing, maintaining stable contact under uneven surfaces or vibration. |
| Plunger | Axially slides under force to drive the contact tip engagement, completing signal transmission. |
| Barrel | Precisely locates internal components and distributes mechanical load to the mounting structure. |
| Contact Tip | Establishes electrical contact with DUT, using spring preload for low-resistance connection and signal integrity. |
| Insulating Sleeve | Surround plunger and contact tip to prevent short circuits between different potentials and isolate housing from conductive path. |
| Base | Secures the probe assembly to the test fixture or PCB and bears external mounting loads. |
