Abstract
A wire pressing frame for a low-voltage electrical appliance comprises a rectangular frame. The rectangular frame comprises a left side wall, a right side wall, a top side wall and a bottom side wall, wherein a front end face and a rear end face are opened; the rectangular frame is formed by bending a bar-shaped conducting metal sheet; both ends of the metal sheet are bent and then are overlapped vertically to form the top side wall or the bottom side wall; a threaded 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 toward the underneath of the rectangular frame. The wire pressing frame, the threaded hole, a boss, the projecting part and a notch are respectively formed through punching shear, drilling and stamping of the metal sheet at one time, and thus a machining process is reduced. The metal sheet forms a self-locking state by inserting the boss at one end into the notch at the other end, and thus structure is firm and does not get deformed. The projecting part at the front side edge of the bottom side wall of the wire pressing frame can cooperate with a packaging body of the low-voltage electrical appliance, and thus the position of the low-voltage electrical appliance is limited and the electrical appliance is prevented from falling off. Meanwhile, the projecting part can be directly welded onto a circuit board of the low-voltage electrical appliance without welding a transition conductor in the middle additionally.
