ABSTRACT:
A coil spring, a pogo pin having the coil spring, and manufacturing methods thereof are provided. The method for manufacturing a coil spring includes i) preparing a metal strip200with a periodically repeated U- or S-shape pattern, and ii) bending the metal strip200at one or more inward bending points210and at one or more outward bending point220, which are formed on the metal strip200, in opposite directions, the inward bending point and the outward bending point being spaced apart from each other. The coil spring and the pogo pin may be manufactured to be small in size and low in manufacturing costs as compared with conventional ones. Further, the coil spring and the pogo pin may provide a sufficient maximum range of motion and spring force of a probe.
