Abstract
The invention discloses a wire pressing frame for a low-voltage apparatus. The wire pressing frame comprises a rectangular frame, wherein the rectangular frame comprises a left side wall, a right side wall, a top side wall and a bottom side wall; a front end face and a rear end face are opened; the rectangular frame is formed through bending a bar-shaped conducting metal sheet; two ends of the metal sheet are bent and then overlapped vertically to form the top side wall or the bottom side wall; a screwed hole is arranged in the top side wall; a front side edge of the bottom side wall is provided with a projecting part; and the projecting part is bent below the rectangular frame. The wire pressing frame, the screwed hole, a boss, the projecting part and a notch are respectively formed one time through punching shear, drilling and stamping of the metal sheet, thus the machining process is reduced. The metal sheet is inserted into the notch at the other end through the boss at one end to form a self-lock, thus the wire pressing frame is firm in structure and is not deformed. The projecting part at the front side edge of a bottom side wall of the wire pressing frame can be matched with a packaging body of the low-voltage apparatus, thus the low-voltage apparatus is limited and prevented from falling. Meanwhile, the projecting part can be directly welded on a circuit board of the low-voltage apparatus without welding a transition conductor in the middle additionally.
