The invention discloses a universal connection terminal, which belongs to the technical field of electronic parts and components. The universal connection terminal comprises a terminal main body, a through hole arranged on the top end of the connection terminal, an absorption part, a bending part, a buckling part, a connecting convex part and a welding end face, wherein the front end of the through hole is provided with a feed belt connecting part; the absorption part is formed by horizontally extending the top end, back to one end of the through hole, of the terminal; the bending part is formed by extending and bending the absorption part; the buckling part is formed by extending the bending part; the connecting convex part is formed by extending and bending the buckling part; and the welding end face is formed by extending and bending the lower lateral surface of the terminal main body. The invention also discloses a preparation process of the universal connection terminal. The universal connection terminal can be widely used for connecting circuit substrates and electronic construction members of the circuit boards in small-sized electronic equipment, and connecting pieces are connected stably and firmly and can be assembled accurately.
