NOVELTY - The utility model claims a reliable elastic sheet structure for 5 G antenna, comprising a main body; the main body is formed by integrally bending the anti-magnetic metal plate; the main body comprises a substrate; the left and right sides of the substrate are bent upwards to form a baffle; the upper end of each baffle are bent inwards to extend out of the limiting sheet; the substrate; two baffle pieces and two limiting pieces are surrounded to form an inverted T-shaped guide groove with opening forward; the inner bottom surface of the inverted T-shaped guide groove is fixed with a strong magnetic sheet; the back end of the substrate is reversely bent and extended with an elastic arm; the elastic arm is obliquely extended upwards; the inner bottom surface of the inverted T-shaped guide groove is fixed with a strong magnetic sheet; the strong magnetic sheet can absorb the terminal of the external device; so that contact is more stable and reliable, at the same time, by setting the convex structure of the arc ball, and matched with the outer surface of the convex structure is coated with a graphene layer, so that the conductive performance is better, not easy to be oxidized, more wearable, and the uniqueness of the contact is more reliable.
