The utility model discloses a puncture terminal structure belongs to circuit connection technical field, include: main body structure, the main body structure includes wiring section, first bending angle, connecting section, second bending angle and press line section, the first bending angle is located between wiring section and connecting section, the second bending angle is located connecting section away from the side of first bending angle, one side of second bending angle is connected with press line section, the main body structure whole presents multistage bending U type structure, the utility model discloses through first bending angle and second bending angle to wiring section, connecting section and press line section are connected, make main body structure partial bending resilience, and under the support of
elastic component simultaneously, make the corrugation puncture surface on press line section have enough contact surface with enameled wire and guarantee enameled wire puncture, and to the optimization of second bending angle, make the main body structure in the pressurized distance inside terminal box lengthen, can avoid enameled wire of
thin line diameter and can not be effectively punctured, improve the reliability of wiring terminal.
