[0097] Example

[0098] like Figures 1 to 17 As shown, this embodiment provides an isolating switch with a novel transmission structure, including an operating system 1 and a transmission disc 2, wherein the operating system 1 is provided with an output shaft 11 and a fixing plate 12; the fixing plate 12 is used to fix the transmission mechanism 13; the transmission disc 2 is provided with a transmission hole 21 on the end surface close to the output shaft 11, and the transmission hole 21 is suitable for the output shaft 11 to be inserted; the transmission disc 2 is also provided with a protrusion 22; the protrusion 22 is an arc-shaped structure, and extends along the movement direction of the transmission disc 2, so that the protrusion 22 is The length of the protrusion 22 corresponds to the movement stroke of the transmission disk 2; a pressure plate 121 is provided on the side of the fixed plate 12 close to the transmission disk 2; the pressure plate 121 abuts against the protrusion 22; the contact system 3 is provided with a moving contact 31 and a stationary contact 32; the arc extinguishing assembly 4 is provided with a plurality of arc extinguishing grids 41 and an insulating plate 42, and arc-starting plates are also provided on both sides of the arc extinguishing grid 41, and the arc generated by the abutment between the moving contact 31 and the stationary contact 32 is transferred to the arc extinguishing grid 41 through the arc-starting plates.

[0099] The transmission disc of the existing transmission structure is only connected to the output shaft of the operating system, resulting in a certain gap between the transmission disc and other parts of the operating system. In addition, due to the influence of the manufacturing process, the matching relationship between the output shaft and the transmission disc is not very stable, so that the transmission disc will be unevenly stressed when rotating, thereby causing distortion or offset, which in turn causes the disconnector to have response delays, poor contact, and operational failure. In an embodiment of the utility model, by providing a transmission hole 21 on one side of the transmission disc 2, and providing a protrusion 22 on the other side corresponding to the transmission hole 21, the output shaft 11 can drive the transmission disc 2 to rotate, and at the same time, the protrusion 22 abuts against the pressure plate 121, and the protrusion 22 rotates relative to the pressure plate 121, so that the two sides of the transmission disc 2 are evenly stressed, and distortion or offset will not occur, further improving the stability of the disconnector.

[0100] Furthermore, if Figure 5 and Figure 6 As shown, an arc groove 122 is also provided on the fixing plate 12, and the arc groove 122 is the movement path of the output shaft 11 and is suitable for limiting the stroke of the output shaft 11. In addition, two fixing plates 12 are provided, and the two fixing plates 12 are provided on both sides of the transmission mechanism 13 and are connected by a plurality of pillars. One end of the output shaft 11 is inserted into the arc groove 122, and the other end of the output shaft 11 passes through the arc groove 122 and is inserted into the transmission hole 21. When the output shaft 11 moves from one end of the arc groove 122 to the other end, the pressure plate 121 moves relatively from one end of the protrusion 22 to the other end, and the movement stroke of the output shaft 11 corresponds to the length of the protrusion 22.

[0101] In the embodiment of the utility model, the transmission mechanism 13 is first driven to drive the output shaft 11 to move from one end of the arc groove 122 to the other end, thereby driving the transmission disk 2 to rotate. At the same time, since the pressure plate 121 abuts against the protrusion 22, during the rotation of the transmission disk 2, the pressure plate 121 moves relatively from one end of the end face of the protrusion 22 to the other end, thereby ensuring that the transmission disk 2 is subjected to uniform force.

[0102] Specifically, the contact system 3 is arranged on a side of the transmission disk 2 away from the operating system 1, and the transmission disk 2 is connected to the contact system 3 through a positioning member 23; under the action of external force, the operating system 1 drives the transmission mechanism 13 to move, drives the output shaft 11 to move, and then drives the transmission disk 2 to rotate, thereby controlling the on and off operation of the contact system 3.

[0103] Furthermore, the contact system 3 is formed by connecting a plurality of contact units in sequence, and the plurality of contact units are connected by bolts.

[0104] Furthermore, if Figure 7 As shown, the contact unit also includes a contact housing 33 and a rotating assembly 34; an arc extinguishing assembly 4 is arranged inside the contact housing 33; the rotating assembly 34 is arranged in the contact housing 33, the rotating assembly 34 is connected to the transmission disk 2, and the rotating assembly 34 is provided with a first groove 3421 and a second groove 3422; the moving contact 31 is arranged in the first groove 3421; the static contact 32 is arranged on the contact housing 33, and one end of the static contact 32 extends into the second groove 3422; under the rotation action of the transmission disk 2, the rotating assembly 34 drives the moving contact 31 to rotate, so that the moving contact 31 abuts against the static contact 32, thereby controlling the on and off of the contact system 3.

[0105] Furthermore, if Fig. 9 and Fig.10 As shown, the rotating assembly 34 includes a first rotating member 341 and a second rotating member 342. The first rotating member 341 is provided with a protrusion 3411 on the top, and a third groove 3412 is provided at the bottom of the first rotating member 341. The protrusion 3411 is suitable for being engaged with the third groove 3412 or the positioning member 23; the second rotating member 342 is engaged with the first rotating member 341, and a long first groove 3421 is provided in the middle of the second rotating member 342. The moving contact 31 is installed in the first groove 3421 and is suitable for synchronously rotating with the second rotating member 342. The side wall of the second rotating member 342 is provided with an annular second groove 3422, and the static contact 32 is inserted into the second groove 3422. During the rotation of the second rotating member 342, the second rotating member 342 drives the moving contact 31 to rotate and abuts against the static contact 32, so that the contact system 3 is connected. In the embodiment of the utility model, the protrusion 3411 is set to an elliptical shape. Of course, it can also be set to a rectangular parallelepiped or a cube. This embodiment does not limit the setting shape of the protrusion 3411. Technical personnel in this field can change the setting shape of the protrusion 3411 according to actual conditions as long as the same technical effect can be achieved.

[0106] When the contact system 3 is connected, the transmission disk 2 is rotated, and through the engagement between the protrusion 3411 and the positioning member 23, the transmission disk 2 drives the first rotating member 341 and the second rotating member 342 to rotate, and then synchronously drives the moving contact 31 to rotate until the moving contact 31 abuts against the static contact 32, and the contact system 3 is connected; when the contact system 3 is disconnected, the transmission disk 2 is rotated in the opposite direction.

[0107] Furthermore, if Figure 8As shown, the arc extinguishing assembly 4 includes a plurality of arc extinguishing grids 41 and an insulating plate 42. The plurality of arc extinguishing grids 41 are arranged in the contact housing 33; the insulating plate 42 is clamped on the arc extinguishing grids 41. In addition, arc-starting plates are also arranged on both sides of the arc extinguishing grids 41. The arc generated by the abutment between the moving contact 31 and the static contact 32 is transferred to the arc extinguishing grids 41 through the arc-starting plates, thereby performing an arc extinguishing operation on the generated arc.

[0108] Furthermore, the contact housing 33 is also provided with a wiring terminal 35 , which is connected to the stationary contact 32 , and is connected to an external wire through the wiring terminal 35 , thereby controlling the on-off operation of the entire circuit system.

In the embodiment of the utility model, by the cooperation and installation of the positioning member 23 and the center hole, the stability of the transmission disk 2 during the rotation process can be improved, thereby enhancing the durability of the isolating switch.

[0110] By rotating the handle 18, the drive shaft 17 is driven to rotate, and the rotation of the drive shaft 17 drives the transmission mechanism 13 to move, and the movement of the transmission mechanism 13 drives the output shaft 11 to move, thereby driving the transmission disk 2 to rotate, and the rotation of the transmission disk 2 drives the rotating assembly 34 to rotate, so that the moving contact 31 abuts against the static contact 32, and the isolating switch is turned on. When the isolating switch needs to be disconnected, the handle 18 can be rotated in the opposite direction.

[0111] Furthermore, an iron core is provided on the electromagnetic driver 15 , and the electromagnetic driver 15 receives an external electrical signal to drive the iron core to strike the transmission mechanism 13 , so that the transmission mechanism 13 moves, thereby disconnecting the isolating switch.
