[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] An auxiliary signal structure of a disconnector, as Figures 1-11 shown, the disconnector includes a housing 10. Among them, the auxiliary signal structure includes a transmission member 60, an auxiliary switch 20, and a push rod 30. A rotating shaft 50 is rotatably arranged in the housing 10, a transmission member 60 is fixedly arranged on the rotating shaft 50, and an auxiliary switch 20 is fixedly arranged in the housing 10.

[0033] The auxiliary switch 20 includes a circuit board 22. Above the circuit board 22, a socket 21 is fixedly arranged. Below the circuit board 22, a microswitch 23 is fixedly arranged. The microswitch 23 is horizontally installed, and a microswitch push rod 231 is fixedly arranged on one side of the microswitch 23. When the microswitch push rod 231 is touched, the microswitch 23 conducts signals to the circuit board 22 and the socket 21.

[0034] In this embodiment, the socket 21 makes the wiring convenient and is easy to disassemble and assemble. The circuit board 22 acts as a flexible wire, and its firmness is better than that of soft wire welding, making it more reliable and firm when assembled in the switch.

[0035] Two horizontally arranged compression springs 40 are fixedly arranged in the housing 10. One end of the compression spring 40 is connected to a push rod 30. The two push rods 30 are symmetrically arranged in the housing 10 and are located on both sides of the transmission member 60. The push rod 30 is correspondingly arranged with the microswitch 23, and a pressing surface 301 is fixedly arranged on the push rod 30. An opening groove is formed at one end of the pressing surface 301. The pressing surface 301 contacts the microswitch push rod 231 of the microswitch 23. When the microswitch push rod 231 slides from the opening groove to the pressing surface 301, the microswitch 23 will be triggered, as Figure 6 、 Figure 7 shown.

[0036] A transmission push block 601 is fixedly arranged on one side of the transmission member 60, as Figure 9As shown, when the rotating shaft 50 drives the transmission member 60 to be positioned at the corresponding angle at this angle, the transmission push block 601 presses the push rod 30 on the left, and the push rod 30 on the right separates from the transmission push block 601 and moves leftward by the restoring force provided by the compression spring 40.

[0037] Similarly, as Figure 10 shown, when driving the transmission member 60 to be positioned at the corresponding angle at this angle, the transmission push block 601 presses the push rod 30 on the right, and the push rod 30 on the left separates from the transmission push block 601 and moves rightward by the restoring force provided by the compression spring 40.

[0038] As Figure 12 shown, when the rotating shaft 50 is at the switch opening position at this angle, the push rod 30 on the left moves accordingly to compress the microswitch 23 on the left. At this time, the microswitch 23 on the left is in the closed state, and the push rod 30 on the right is released and separated from the microswitch 23 on the right. At this time, the microswitch 23 on the right is in the open state.

[0039] In this embodiment, the structure of the disconnecting switch is improved, the complexity of the auxiliary switch is reduced, the processing is simplified, and the cost and failure rate are reduced; the circuit board 22 replaces the flexible wire and the auxiliary seat, saving cost, and providing a stable structure to make the assembly more firm. A socket 21 is provided for the customer to wire, making it more convenient for the customer to wire. The circuit board 22 replaces the flexible wire and the auxiliary seat, which can realize modularization, making the processing and installation more convenient, and making the structure more stable and firm. The two groups of auxiliary switch materials are unified, and there will be no misassembly. The auxiliary switch is opened and closed by the mechanism.
