Abstract:
1. A side grounded structure for a combined battery lid for a mobile communications terminal, comprising: a metallic battery lid having a plastic layer, the metallic battery lid and the plastic layer having similar shape and size; an elastic contact sheet set between the metallic battery lid and the plastic layer, said elastic contact sheet being electrically connected to the metallic battery lid and having an elastic curvature configured to connect to a grounded down-lead of a circuit board, wherein the elastic contact sheet has an inner side and an outer side with the inner side extending with a similar curvature as the metallic battery lid and the plastic layer, wherein the elastic contact sheet has a humped area in contact with the metallic battery lid, wherein the outer side of the elastic contact sheet curves inward and extends from one side of the plastic layer to another side of the plastic layer, and wherein the elastic contact sheet partially wraps up the plastic layer; and an electrically conducting contact sheet on a main enclosure corresponding to the elastic curvature, the elastic curvature being connected to the grounded down-lead of the circuit board, wherein the electrically conducting contact sheet extends through a hole in a battery side of the main enclosure, wherein the elastic curvature of the elastic contact sheet between the metallic battery lid and the plastic layer is configured to ground the metallic battery lid.
