Title:
MULTI-LAYER MEMS SPRING PIN
Document Type and Number:
WIPO Patent Application WO/2020/213899
Kind Code:
A1
Abstract:
A three-layer MEMS spring pin of the present invention comprises: a lower-layer spring pin, in which a lower-layer wave is connected between a lower-layer top plunger and a lower-layer bottom plunger; an upper-layer spring pin, in which an upper-layer wave is connected between an upper-layer top plunger and an upper-layer bottom plunger; a middle-layer top tip interposed between the upper-layer top plunger and the lower-layer top plunger; and a middle-layer bottom tip interposed between the upper-layer bottom plunger and the lower-layer bottom plunger. According to the configuration of the present invention as described above, the effects of preventing bending, stabilizing a stroke due to the multi-layer spring, and enhancing contact characteristics due to the multi-layer plunger are expected.
