▎ 摘　　要

NOVELTY - Electric connection structure comprises circuit board, which is provided with an inserting hole, and a metal elastic sheet, and an inserting terminal, where the metal elastic sheet comprises a base band and many respectively sheets are connected with the base band, the base band is wrapped on at least a portion of the outer circumference of the inserting terminal, the elastic sheet is provided with a convex part protruding outwards, and the convex part is propped against the surface of the circuit board, the inserting terminal is electrically connected with the circuit board through the metal elastic sheet. USE - The electric connection structure is useful for circuit board used in charging gun or charging seat of electric automobile and in electric vehicle charging system. ADVANTAGE - The structure: has a metal elastic sheet provided with a base band and multi sheets that are connected with the base band, can wrap the base band on a portion of an outer circumference of an inserting terminal, can form the elastic sheet with a convex portion protruding outward, uses convex unit i.e. propped against a surface of circuit board, provides inserting terminal i.e. electrically connected to circuit board through the metal elastics sheet. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) charging seat; and (2) automobile. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the electric connection structure.
