[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0033] Reference below Figure 1-Figure 5 The anti-offline switch according to the embodiment of the utility model is described.

[0034] like Figure 1-Figure 5 As shown, the anti-offline switch includes a bottom shell 100 and a shell cover 200, and the bottom shell 100 and the shell cover 200 are connected to form a shell. The bottom shell 100 is provided with a wire clamping groove 110, one side of the wire clamping groove 110 is in contact with the side wall of the bottom shell 100, and the two sides of the wire clamping groove 110 are respectively provided with a first metal part 310 and a second metal part 320, and a metal contact part 330 is hinged in the middle of the wire clamping groove 110. Different from the prior art, the wire clamping groove 110 in this embodiment is arranged close to the side wall of the bottom shell 100, and the side wall of the bottom shell 100 can be used as the side wall of the wire clamping groove 110, which can reduce the molding material and improve the structural strength of the wire clamping groove 110.

[0035] Among them, the first metal part 310 and the second metal part 320 are respectively provided with a clamping part 410, and fixing teeth 411 are provided on both sides of the clamping part 410. The fixing teeth 411 are used to fix the clamping part 410 in the wire clamping groove 110. The middle part of the clamping part 410 is provided with a wire clamping claw 412, and the wire clamping claw 412 is used to clamp the cables in the wire clamping groove 110.

[0036] Specifically, the structures of the first metal part 310 and the second metal part 320 are also improved, especially the clamping part 410. The clamping method of the clamping part 410 using fixed teeth 411 and wire clamping claws 412 greatly reduces the sheet metal stamping materials of the metal parts and simplifies the processing procedures. While improving the clamping force, it effectively reduces the material cost and improves the production efficiency, meeting the production needs of reducing costs and increasing efficiency.

[0037] In some embodiments of the present invention, Figure 3-Figure 5 As shown, the fixed teeth 411 on both sides of the clamping part 410 are arranged at equal intervals, and at least three groups of fixed teeth 411 are arranged on each side. Specifically, the fixed teeth 411 on both sides of the clamping part 410 are structurally optimized, and the fixed teeth 411 on both sides correspond to each other, ensuring that the force on both sides is uniform, thereby improving the connection stability between the metal part and the clamping groove 110.

[0038] Furthermore, if Figure 3-Figure 5As shown, the fixed teeth 411 and the plane of the clamping portion 410 form an inclined angle, and the inclination direction of the fixed teeth 411 is in the same direction as the clamping claw 412. Specifically, the fixed teeth 411 and the surface of the clamping portion 410 are tilted by 1° to 3°. When the metal part is pressed into the clamping groove 110, the fixed teeth 411 of the clamping portion 410 can be pressed down along the side wall of the clamping groove 110. When the clamping portion 410 moves outward at the bottom of the clamping groove 110, the fixed teeth 411 form a reverse limit with the displacement direction, and the fixed teeth 411 hook the side wall of the clamping groove 110, so that the metal part is firmly fixed in the clamping groove 110.

[0039] In some embodiments of the present invention, Figure 3-Figure 5 As shown, a clamping groove 413 is provided in the middle of the clamping portion 410, and wire clamping claws 412 are provided on both sides of the clamping groove 413. The cable is placed in the clamping groove 413, and the wire clamping claws 412 are pressed toward the clamping groove 413. Specifically, the clamping groove 413 provides space for placing the cable, so that the wire clamping claws 412 can clamp the cable at a specified position.

[0040] In some embodiments of the present invention, Figure 3-Figure 5 As shown, the wire clamping claw 412 adopts a right-angle triangle structure, and the right-angle sides of the wire clamping claws 412 on both sides are arranged to face each other. When the two wire clamping claws 412 are pressed down into the clamping groove 413, the oblique sides of the two wire clamping claws 412 are close to each other. Specifically, the two wire clamping claws 412 are stamped from the clamping groove 413, which efficiently utilizes the plate material to reduce the manufacturing cost.

[0041] Furthermore, if Figure 4 and Figure 5 As shown, the clamping claw 412 is bent in two sections, so that when the clamping claw 412 is pressed down, a clamping area can be formed to accommodate the cable.

[0042] In some embodiments of the present invention, Figure 4 and Figure 5 As shown, the first metal member 310 and the second metal member 320 are respectively provided with a contact portion 420 , and the contact portion 420 extends to below the metal contact member 330 .

[0043] Specifically, the contact portion 420 and the clamping portion 410 are integrally formed. When the metal contact member 330 rotates and connects the cables at both ends, the switch is turned on.

[0044] In some embodiments of the present invention, Figure 1-Figure 3 As shown, it includes a button 210, which is rotatably connected to the middle of the wire clamping groove 110 and is located above the metal contact piece 330. The button 210 is used to press and switch the working state of the metal contact piece 330.

[0045] Specifically, the button 210 is made of insulating material, is embedded with the metal contact piece 330 , and works synchronously with the metal contact piece 330 .

[0046] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the shell cover 200 is provided with a slot at a position corresponding to the button 210 , and the button 210 protrudes from the surface of the shell cover 200 .

[0047] In some embodiments of the present invention, the first metal member 310 and the second metal member 320 are respectively formed by integral stamping.
