A pogo pin for an ultra-high current, the pogo pin comprising:
- a first plunger;
- a coil spring configured to elastically support the first plunger;
- and
- an outer cylinder allowing the coil spring to be mounted therein and configured to guide sliding of the first plunger,
- wherein a plurality of brushes 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 has an insertion part passing between the plurality of brushes and located inside the first plunger, with each turn of the insertion part being wound in close contact with each other.
A pogo pin for an ultra-high current, the pogo pin comprising:
- a first plunger;
- a coil spring configured to elastically support the first plunger;
- and
- an outer cylinder allowing the coil spring to be mounted therein and configured to guide sliding of the first plunger,
- wherein a plurality of brushes 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, wherein a part of each of the brushes in contact with the outer cylinder or a vicinity of the part of the brush in contact with the outer cylinder is chamfered.
A pogo pin for an ultra-high current, the pogo pin comprising:
- a first plunger and a second plunger;
- a coil spring configured to elastically support the first plunger and the second plunger on opposite ends of the coil spring, respectively;
- and
- an outer cylinder (50) allowing the coil spring to be mounted therein and configured to guide sliding of each of the first plunger and the second plunger,
- wherein the second plunger comprises:
- a 2-1 plunger cylindrical part of a cylindrical shape;
- and
- a 2-2 plunger cylindrical part, which is shaped cylindrically, having a step and connected to the 2-1 plunger cylindrical part, with the 2-2 plunger cylindrical part being located farther from the coil spring than the 2-1 plunger cylindrical part and having an outer diameter smaller than an outer diameter of the 2-1 plunger cylindrical part, and
- the outer cylinder (50) comprises a U-shaped or inverted U-shaped window (52b) and a holding piece (52a) formed by punching the window,
- wherein the holding piece (52a) extends in a longitudinal direction of the second plunger, and after the outer cylinder and the second plunger are assembled with each other, a free end of the holding piece (52a) is held on the step to be prevented from being removed.
