[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0017] Reference Figure 1-3 A wire connection structure for a wall switch includes a mounting shell 1 and a mounting bolt 2 threadedly embedded at its end, a threaded ring 3 embedded at the top of the mounting shell 1, a vertical bolt 4 passing through the middle thread of the threaded ring 3, a conductive plate 5 fixed to the bottom of the inner wall of the mounting shell 1, a supporting plate 6 fixed to the top of the conductive plate 5, a metal plate 7 movably placed on the top of the supporting plate 6, and a lever plate 8 fixed to the top of the metal plate 7.
[0018] Preferably, a lower jaw 10 is integrally formed upward at the top of one side of the lever plate 8, and a protrusion 12 is integrally formed downward at the bottom of the other side of the lever plate 8. The lower jaw 10 cooperates with the protrusion 12 to bite the wire, and the lower jaw 10 and the protrusion 12 press the wire into multiple corner bends, so that the wire is firmly fixed in the mounting shell 1.
[0019] Preferably, a plurality of upper jaw blocks 11 are fixed to the top of the inner wall of the mounting shell 1, and a metal spring sheet 9 is arranged between the protrusion 12 and the top of the metal plate 7. The metal spring sheet 9 can lift one side of the lever plate 8 to quickly reset the lever plate 8 for easy use.
[0020] Preferably, the side of the conductive plate 5 is bent vertically upward, the thread of the mounting bolt 2 passes through the portion of the conductive plate 5 that is bent vertically upward, the conductive plate 5 is connected to the mounting bolt 2, and the mounting bolt 2 is installed in the switch so that the conductive plate 5 is connected to the switch.
[0021] Preferably, the support plate 6 is made of metal, the top of the support plate 6 is semicircular, and the bottom of the metal plate 7 is provided with an arc-shaped groove. The metal plate 7 can rotate on the top of the support plate 6 to form a lever, thereby greatly increasing the strength of the lever plate 8 to clamp the wire.
[0022] Preferably, the metal plate 7 is located on one side in the middle of the lever plate 8, and the bottom of the vertical bolt 4 is spherical and rests against the other side of the top of the lever plate 8. The vertical bolt 4 moves downward in the threaded ring 3, and the vertical bolt 4 pushes one side of the lever plate 8 downward, so that the protrusion 12 on the other side of the lever plate 8 moves upward to clamp the wire.
[0023] Among them, the distance between the metal plate 7 and one side of the lever plate 8 is smaller than the distance between the metal plate 7 and the other side of the lever plate 8, so that the moving distance on one side of the lever plate 8 is short and the pressure is large, and the moving distance on the other side of the lever plate 8 is long and the pressure is small. The lever principle is used to increase the pressure of the raised part 12 on the top of the lever plate 8 on the wire.
[0024] In the utility model, when in use, first, use a screwdriver to remove the mounting bolt 2 from the mounting shell 1, then screw the mounting bolt 2 through the switch housing into the mounting shell 1, so that the mounting shell 1 is installed on the switch housing, and then weld the switch connecting wire to the mounting bolt 2, and then insert the conductor of the wire into the mounting shell 1, and then use a screwdriver to twist the vertical bolt 4 to move it downward in the threaded ring 3, the end of the vertical bolt 4 is against the lever plate 8, one side of the lever plate 8 is pressed down and the metal spring 9 is bent, and at the same time the other side of the lever plate 8 is tilted, so that the raised portion 12 on the top of the lever plate 8 presses the wire on the lower jaw 10, the lower jaw 10 and the raised portion 12 bite the wire, and the wire is fixed in the mounting shell 1, so that the switch is connected to the circuit.
