Probe-connection-type pogo pin and manufacturing method thereof

A method for manufacturing a probe-connection-type pogo pin including an upper probe part (100), a lower probe part (200′), and an elastic part (300) positioned between the upper probe part and the lower probe part, wherein the upper probe part and the lower probe part are connected to each other through the elastic part only, the method comprising:

• a) cutting a metal plate according to planar figures represented on the metal plate, wherein the represented planar figures include a planar figure of upper probe part (100′) with a planar figure of tip portion (120′) formed on an upper end of the planar figure of upper probe part, a planar figure of lower probe part (200′) with a planar figure of tip portion (220′) formed on a lower end of the planar figure of lower probe part, and a planar figure of strip-shaped elastic part (300′) formed to connect the planar figure of upper probe part (100′) and the planar figure of lower probe part (200′) to each other,
• b) forming a raw pogo pin made of an upper probe part, a lower probe part and an elastic part, which are made in one body, by forming the lower probe part (200′), which is shaped partly or wholly in cylindrical shape, from a plate of the planar figure of lower probe part (200′) using rolling means, winding the elastic part (300) to surround an outside of the lower probe part (200′), and making the upper probe part (100) shaped partly or wholly in cylindrical shape, and
• c) hardening the raw pogo pin through heat treatment and plating the raw pogo pin, and
• wherein the probe-connection-type pogo pin further includes a spring which has a predetermined elasticity,
• wherein the lower probe part (200′) includes an insertion portion which may be positioned in the middle of the spring, and
• wherein the spring has an electrical path in proportion to the number of turns of the spring and has a spiral structure of a coil causing resistance and inductance components.
