[0019] The present invention will be further described below with reference to embodiments, but the present invention is not limited to these embodiments. Any similar variations using the present invention should be included in the protection scope of the present invention. The use of directional terms such as up, down, front, back, left, right, middle, inside, and outside in the present invention is only for the convenience of clear description and is not intended to limit the technical solution of the present invention.

[0020] like Figures 1-7 As shown, this utility model provides a double-layer disconnection connection device, including two parallel screws 1. Each screw 1 has an insulating layer 2 covering its middle section. From bottom to top, each screw 1 is provided with two nuts 3, a first insulating sleeve 4, a conductive element 5, a second insulating sleeve 6, and a locking nut 7. The nuts 3 are threaded to the lower end of the screw 1. The first insulating sleeve 4 is fitted onto the insulating layer 2 of the screw 1. The conductive element 5 is fixedly connected to the insulating layer 2 of the screw 1. The conductive element 5 includes a first conductive plate 8. A second conductive plate 9 and a third conductive plate 10 are vertically connected to the upper and lower ends of the first conductive plate 8, respectively. The third conductive plate 10 is located above the first insulating sleeve 4. One end of the second conductive plate 9 is connected to the first conductive plate 8, and the other end is provided with a conductive element. The second conductive plate 9 is located below the second insulating sleeve 6 and is protruding 11. A rotary toggle switch is connected between the two screws 1. The rotary toggle switch includes a first conductor 12, a second conductor 13 and an insulating handle 14. The first conductor 12 and the second conductor 13 are fixedly connected to the insulating handle 14. The first conductor 12 is located above the second conductor 13 and is located between the locking nut 7 and the second insulating sleeve 6. One end of the first conductor 12 is rotatably sleeved on the left screw 1 and the other end of the first conductor 12 is provided with a notch. The notch of the first conductor 12 is movably sleeved on the right screw 1. The two ends of the second conductor 13 are in movable contact with the two conductive protrusions 11 respectively. The locking nut 7 is threadedly connected to the upper end of the screw 1.

[0021] Working principle:

[0022] The first circuit wiring method is as follows: On each screw 1, the end of a first wire is connected between two nuts 3, and the two first wires are connected through the screw 1 and the first conductor 12.

[0023] The second circuit wiring method is as follows: On each screw 1, the end of a second wire is connected between the conductive part 5 and the first insulating sleeve 4, and the two second wires are connected through the conductive part 5, the conductive protrusion 11, and the second conductor 13.

[0024] The first conductor 12 is rotatably sleeved with the screw 1 on the left. Manually turning the insulating handle 14 will cause the first conductor 12 to rotate around the screw 1 on the left, thereby causing the second conductor 13 to rotate. Figure 6 , Figure 7 As shown, when the notch at the right end of the first conductor 12 disengages from the screw 1 on the right side, both the first and second wires are no longer connected. Figure 2 As shown, when the notch at the right end of the first conductor 12 is connected to the screw 1 on the right side, the first wire is connected. At the same time, the second conductor 13 is connected to the conductive protrusions 11 on both sides, and the second wire is connected. Then, the locking nut 7 on the screw 1 is tightened to fix the first conductor 12, and then the second conductor 13 is also fixed.

[0025] The first insulating sleeve 4 and the second insulating sleeve 6 can provide support and have a certain height, and can also improve the electrical performance of the product (increasing the creepage distance of the two circuits).

[0026] This utility model, through the conductive element 5 and the dual conductor design, realizes the conduction or disconnection of two circuits on a single connector, reducing space occupation, saving usage costs, and making it easier for users to use in more complex environments.

[0027] Furthermore, both the second conductive plate 9 and the third conductive plate 10 are sleeved on the screw 1. A limiting block 15 is provided on the side of the insulating layer 2 of the screw 1, and the second conductive plate 9 is hung on the limiting block 15. The limiting block 15 provides support and positioning for the insulating component 16.

[0028] Furthermore, such as Figure 1 As shown, it also includes an insulating component 16, which includes two cylindrical bodies 17. The two cylindrical bodies 17 are fixedly connected by a connecting plate 18. The two cylindrical bodies 17 are respectively fixedly sleeved on the insulating layer 2 of the two screws 1 and sleeved on the outside of the conductive component 5. The upper and lower ends of the conductive component 5 extend out of the cylindrical body 17.

[0029] Furthermore, such as Figure 3 As shown, it also includes a mounting plate 19, which has two through holes. The lower ends of both cylindrical bodies 17 are provided with external threads. The mounting plate 19 is fitted onto the external threads of the two cylindrical bodies 17 through the two through holes. Large nuts 20 are threaded onto the external threads of the cylindrical bodies 17 on the underside of the mounting plate 19. The entire connector can be easily installed on the electrical cabinet door via the mounting plate 19. The electrical cabinet door needs to have two mounting holes for the screw 1 to pass through.

[0030] Furthermore, two first washers 21 are fitted on the screw 1 between the two nuts 3.

[0031] Furthermore, a second washer 22 is fitted on the upper and lower sides of the first conductor 12 on the left screw 1, and a bowl-shaped washer 23 is fitted on the upper and lower sides of the first conductor 12 on the right screw 1.

[0032] Furthermore, the screw 1 and the insulation layer 2 are integrally injection molded, which can improve the electrical insulation performance.
