Description

Technical Field

[0001] This utility model relates to the field of probe technology, specifically to a high-current probe assembly. Background Technology

[0002] Probes are an important part of electronic product connectors. In actual use, with the existing probe technology, if the current is small, even if the current flows through the aforementioned tiny path, it will not affect the probe's lifespan. However, when the probe needs to carry a large current, the current concentration at the tiny contact area can easily deteriorate and cause the material to melt or change its thermal properties, thus affecting the probe's lifespan.

[0003] With the rapid development of new energy, chip testing requires high-current probes (tens to hundreds of amperes) with low contact resistance and large current throughput.

[0004] Therefore, it is of great significance to provide a high-current probe assembly that can solve the problems existing in the current technology. Utility Model Content
