摘要： Disclosed a capacitive stylus pen, comprising a holding structure comprising a pen holder, and a pen tip assembly comprising a pen tip shaft and a strain sensor, the strain sensor comprising a resilient element and a strain gauge on the resilient element, and the resilient element being connected to the pen tip shaft and the holding structure, wherein the resilient element is L-shaped, the pen tip assembly further comprises an energy absorption structure arranged on the pen tip shaft, and the energy absorption structure is connected to the holding structure. The L-shaped resilient element in cooperation with the energy absorption structure forms a double-support elastic buffering structure and reduces deformation rate of the strain gauge with same load when the capacitive stylus pen itself rotates to different angles; and the energy absorption structure is added to share part of the stress on the resilient element to reduce the resilient element's deformation.

摘要： A rectangular impact-resistant elastic connector includes an upper contact part, first and second side plates, first and second S-shaped lift force arms and a bottom plate, wherein the first and second side plates are connected with the bottom plate, the first S-shaped lift force arm has an end connected with the upper contact part and an end connected with one end of the first side plate, and the second S-shaped lift force arm has an end suspended below the upper contact part and an end connected with one end of the second side plate. The S-shaped lift force arm structures having the advantage of greater elasticity over other force arm structures under the same unit size are used to provide an elastic force, so that the size of the connector is reduced. The side plates protect the force arms, thus, improving the overall impact resistance of the connector.
