| 摘要 | The present invention relates to a flat plate folding type coil spring, a single body type pogo pin having a flat plate folding type coil spring, and a manufacturing method thereof. The method for manufacturing a flat plate folding type coil spring includes the steps of i) preparing a band type metal plate (200) to which a U- or S-shaped pattern is recursively connected, and ii) bending the band type metal plate (200) at one or more inward bending points (210) and an outward bending point (220) which are formed on the band type metal plate, in the direction opposite from one another, such that the inward bending point (210) and the outward bending point (220) are spaced apart from each other. The coil spring and the pogo pin according to the present invention are small in size and have low manufacturing costs as compared with conventional ones, while providing a sufficient maximum movement range and a spring force of a probe. | ||||||
