Abstract: A pogo pin for an ultra-high current includes a first plunger (20), a coil spring (10) configured to elastically support the first plunger, and an outer cylinder (40) allowing the coil spring to be mounted therein and configured to guide sliding of the first plunger, wherein a plurality of brushes (21) is provided on one end of the first plunger such that the plurality of brushes is capable of sliding while elastically contacting an inner surface of the outer cylinder, and the coil spring (10) has an insertion part (I1) passing between the plurality of brushes and located inside the first plunger (20), with each turn of the insertion part being wound in close contact with each other.

Abstract: Proposed is a pogo pin including a plunger module (1) guided by a barrel (3) and whose length exposed to an outside of the barrel (3) is variable, wherein the plunger module (1) includes a first brush set (11) in which a plurality of brushes with a first side thereof fixed and a second side thereof elastically contacting an inner surface of the barrel (3) is arranged in an annular shape, and a second brush set (21) in which a plurality of brushes with a first side thereof fixed and a second side thereof elastically contacting the inner surface of the barrel (3) is arranged in an annular shape.
