  • the lever handle before a wire is inserted, the lever handle is first rotated to 90° to abut against the conductive terminal for elastic deformation to reserve a wire insertion space, then the wire is inserted, and finally the lever handle is rotated to an initial position to remove its abutting force against the conductive terminal, so that the conductive terminal elastically resets, and abuts against and fixes the wire.
  • this switch with the lever handle avoids inconvenience of screws, the switch requires an operator to apply an external force to rotate the lever handle to the initial position, which leads to complex operations. The wire may be driven to withdraw from the conductive terminal if the operation is improper.
  • an objective of the present invention is to provide an auto-reset wiring switch, which makes a maximum rotation angle of a lever handle less than 55° by making an inclination angle of a first inclined plane not exceed 55°, so that the lever handle can be automatically reset by an elastic restoring force of an elastic sheet, and the objective of automatic reset during the wiring of the switch can be achieved.

  • the second inclined plane is parallel to the first inclined plane.
  • the copper sheet is provided with a first plate, a second plate formed by bending and extending from the first plate, and a third plate formed by bending and extending from the second plate, the first plate abuts against the second inclined plane, and the third plate and the elastic sheet jointly clamp the wire.
  • a convex sheet is formed by tearing the third plate and bending in a direction close to the first plate, and the convex sheet abuts against the wire.
  • a through groove is formed by penetrating a surface of the second plate, and the wire runs through the through groove and reaches contact with the convex sheet.
  • the through groove extends to the first plate
  • the elastic sheet is provided with a contact part and a positioning part
  • the contact part is located in the through groove corresponding to the second plate
  • the positioning part is located in the through groove corresponding to the first plate.
  • the elastic sheet is provided with a mounting part attached to the first plate, an elastic part is formed by bending and extending from the mounting part, the elastic part is bent and extends in a direction close to the second plate to form a contact part, and the contact part abuts against the wire.
  • an included angle between the mounting part and the elastic part is an acute angle, and the mounting part is bent to form a positioning part to clamp the insulating body.
  • the lever handle is provided with an operating part and an abutting part, the operating part is located outside the wire insertion hole for the operator to apply an acting force, and the abutting part is accommodated in the wire insertion hole to abut against the elastic part.
  • the insulating body is provided with a plurality of wire insertion holes arranged in two rows, each of the wire insertion holes accommodates one lever handle and one stationary terminal, and a row of movable terminals is located between the two rows of wire insertion holes.
  • the present invention may achieve the following beneficial effects:
  • the inclination angle of the first inclined plane does not exceed 55°, and the lever handle abuts against the first inclined plane when rotating to the maximum angle. Therefore, a rotation angle of the lever handle does not exceed 55°, so that the lever handle can be automatically reset to the initial position by the elastic restoring force of the elastic sheet. Therefore, after the wire is inserted into the wire insertion hole of the auto-reset wiring switch, the lever handle is automatically reset, and the elastic sheet clamps the wire terminal, which is simple in operation. This prevents the wire terminal from being withdrawn from the wire insertion hole when the lever handle is reset, and a risk of poor contact between the auto-reset wiring switch and the wire is reduced.

  • a plurality of wire insertion holes 21 are formed by penetrating the insulating body 2 and are arranged in two rows, each of the wire insertion holes 21 accommodates one lever handle 3 and one stationary terminal 4, and a row of movable terminals 6 is located between the two rows of wire insertion holes 21.
  • the switch button 1 drives the movable terminals 6 to switch a connection between the two rows of stationary terminals 4, to achieve a double control function of the auto-reset wiring switch 100.
  • only one row of stationary terminals 4 may be provided, so that single control of the auto-reset wiring switch 100 is achieved. No limitation is imposed herein.
  • Each of the wire insertion holes 21 is provided with a first inclined plane 22 and a second inclined plane 23 that are parallel to each other, and an inclination angle of the first inclined plane 22 is less than 55°.
  • the inclination angle of the first inclined plane 22 is 45°, and when the wire 5 is inserted in the wire insertion hole 21, the wire 5 is located between the first inclined plane 22 and the second inclined plane 23.
  • One lever handle 3 is correspondingly and pivotally connected in one wire insertion hole 21, and the lever handle 3 abuts against the first inclined plane 22 when rotating to a maximum angle, so that the first inclined plane 22 limits excessive rotation of the lever handle 3.
  • the lever handle 3 is provided with an operating part 31 and an abutting part 32, the operating part 31 is located outside the wire insertion hole 21 for the operator to apply an acting force, and the abutting part 32 is accommodated in the wire insertion hole 21 to abut against the stationary terminal 4.
  • Each stationary terminal 4 includes a copper sheet 41 and an elastic sheet 42 that match each other.
  • the copper sheet 41 is provided with a first plate 411, a second plate 412 formed by bending and extending from the first plate 411, and a third plate 413 formed by bending and extending from the second plate 412.
  • the first plate 411 abuts against the second inclined plane 23.
  • a convex sheet 4131 is formed by tearing the third plate 413 and bending in a direction close to the first plate 411, and the convex sheet 4131 abuts against the wire 5, so as to increase an elastic force of the convex sheet 4131 abutting against the wire 5 and improving abutting stability of the convex sheet 4131.
  • a through groove 4121 is formed by penetrating a surface of the second plate 412.
  • the through groove 4121 extends to the first plate 411.
  • the elastic sheet 42 is provided with a mounting part 421 attached to the first plate 411, and an elastic part 422 is formed by bending and extending from the mounting part 421.
  • the elastic part 422 abuts against the abutting part 32, and extends in a direction close to the second plate 412 to form a contact part 424, and the contact part 424 is located in the through groove 4121 corresponding to the second plate 412, so that the contact part 424 and the convex sheet 4131 jointly clamp the wire 5.
  • the mounting part 421 is bent to form a positioning part 423, and the positioning part 423 is located in the through groove 4121 corresponding to the first plate 411 and clamps the insulating body 2 to prevent the elastic sheet 42 from shaking in the insulating body 2.
  • an included angle between the mounting part 421 and the elastic part 422 is an acute angle, to increase an elastic restoring force of the elastic sheet 42.
  • a process of connecting the wire 5 to the auto-reset wiring switch 100 is as follows: The operator first presses the operating part 31 to make the lever handle 3 rotate until the abutting part 32 abuts against the elastic sheet 42 to produce a maximum elastic deformation when the lever handle 3 abuts against the first inclined plane 22. In this case, the elastic part 422 experiences a maximum displacement, and at this time, the wire 5 can be inserted into the wire insertion hole 21 without resistance and run through the through groove 4121.
  • an elastic restoring force of the elastic sheet 42 drives the elastic part 422 to restore from the displacement, and then abut against the abutting part 32 to drive the lever handle 3 to return to an initial position.
  • the contact part 424 and the convex sheet 4131 jointly clamp the wire 5. Because the elastic part 422 and the convex sheet 4131 have relatively high elasticity, the elastic part 422 and the convex sheet 4131 can stably clamp the wire 5, reducing a risk of poor contact between the wire 5 and the stationary terminal 4. It should be noted that, if the wire 5 is a hard wire 5, the wire 5 can be directly inserted into the wire insertion hole 21 to squeeze the elastic part 422 for a deformation and displacement without pulling the lever handle 3. In this case, wiring of the auto-reset wiring switch 100 in the present invention becomes easier.
  • the operator flips the operating part 31 to rotate the lever handle 3, so that the abutting part 32 abuts against the elastic part 422 to stay away from the wire 5 until the wire 5 is separated.
  • the wire 5 can be withdrawn from the wire insertion hole 21 without resistance, to achieve the objective of separating the wire 5 from the auto-reset wiring switch 100.
  • the lever handle 3 can still return to the initial position by the elastic restoring force of the elastic sheet 42.
  • Embodiment 2 has the same wiring structure as Embodiment 1. The only difference lies that an upper portion of one insulating body 2 is covered with two switch buttons 1, and details are no longer described herein.
