[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0024] This application discloses a conductive copper busbar for a switching device. (Refer to...) Figure 1 and Figure 2 A conductive copper busbar for a switchgear includes a conductive copper busbar body 1, a connecting bolt 101 penetrating the surface of the conductive copper busbar body 1, a connecting nut 102 threadedly connected to one end of the connecting bolt 101, a protective frame 2 slidably sleeved on the surface of the conductive copper busbar body 1, and a sealing component 3 provided on the surface of the protective frame 2.

[0025] The sealing component 3 includes several sealing plates 31, which are slidably connected to the top and bottom of the protective frame 2. Each sealing plate 31 has a pull plate 32 fixedly connected to its surface. The protective frame 2 has several tension springs 33 fixedly connected to its surface, with one end of each tension spring 33 fixedly connected to the surface of each pull plate 32. A connecting component 4 is fixedly connected to the surface of each sealing plate 31, and the connecting component 4 is fixedly connected to the surface of another sealing plate 31. After the conductive copper busbar body 1 is connected, the sealing plate 31 is pulled by the connecting component 4, and then the protective frame 2 is slid so that the protective frame 2 is fitted onto the connection point of the conductive copper busbar body 1. Then the connecting component 4 is released, and the tension springs 33 drive the pull plates 32 to reset. The pull plates 32 drive the sealing plates 31 to reset, so that the sealing plates 31 seal the gap between the protective frame 2 and the conductive copper busbar body 1. The connecting component 4 avoids affecting the position of the sealing plates 31, so that the sealing plates 31 can adapt to gaps of different widths. This allows the sealing plates 31 to cooperate with the protective frame 2 to protect the connection point of the conductive copper busbar body 1.

[0026] Reference Figure 1 and Figure 2 A support plate 3101 is fixedly installed on the surface of the sealing plate 31. A sliding groove 3102 is formed on the surface of the support plate 3101. A sliding rod 3103 is fixedly installed on the surface of the protective frame 2. The surface of the sliding rod 3103 is slidably connected to the inner cavity of the sliding groove 3102. By sliding the surface of the sliding rod 3103 to the inner cavity of the sliding groove 3102, the position of the sealing plate 31 is stabilized by the sliding rod 3103 and the support plate 3101, so as to prevent the sealing plate 31 from moving too much and separating from the protective frame 2.

[0027] Reference Figure 1 and Figure 2 A positioning block 3104 is fixedly installed at one end of the slide rod 3103. The surface of the positioning block 3104 is slidably connected to the surface of the support plate 3101. The positioning block 3104 can stabilize the position of the slide rod 3103 inside the slide groove 3102, and prevent the slide rod 3103 from separating from the slide groove 3102 and affecting the position of the sealing plate 31.

[0028] Reference Figure 2 and Figure 3 The connecting assembly 4 includes several brackets 41, which are fixedly installed on the surfaces of several sealing plates 31. A connecting sleeve 42 is rotatably connected inside one bracket 41, and a connecting rod 43 is rotatably connected inside another bracket 41. The surface of the connecting rod 43 is slidably connected to the inner cavity of the connecting sleeve 42. The connecting sleeve 42, the connecting rod 43 and the sealing plate 31 are rotatably connected through the brackets 41, and the inner cavity of the connecting sleeve 42 is slidably connected to the surface of the connecting rod 43. This prevents the connecting rod 43 and the connecting sleeve 42 from affecting the position of the sealing plate 31 after the sealing plate 31 is reset, so that the sealing plate 31 can adapt to gaps of different widths.

[0029] Reference Figure 2 and Figure 3 A connecting block 44 is fixedly installed at one end of the connecting sleeve 42 and the connecting rod 43 respectively. A support rod 45 is fixedly connected inside each of the brackets 41. The inner cavity of the connecting block 44 is slidably connected to the surface of the support rod 45. The connecting rod 43, the connecting sleeve 42 and the bracket 41 are rotatably connected by the slidable connection between the inner cavity of the connecting block 44 and the surface of the support rod 45.

[0030] Reference Figure 3 and Figure 4 A support block 4201 is fixedly installed on the inner wall of the connecting sleeve 42, and a support groove 4202 is opened on the surface of the connecting rod 43. The surface of the support block 4201 is slidably connected to the inner cavity of the support groove 4202. The slidable connection between the surface of the support block 4201 and the inner cavity of the support groove 4202 stabilizes the position of the connecting rod 43 inside the connecting sleeve 42.

[0031] Reference Figure 3 and Figure 4 A limiting block 4203 is fixedly installed on the surface of the support block 4201, and a limiting groove 4204 is formed in the inner wall of the support groove 4202. The inner cavity of the limiting groove 4204 is slidably connected to the surface of the limiting block 4203. By slidingly connecting the surface of the limiting block 4203 with the inner cavity of the limiting groove 4204, the position of the support block 4201 inside the support groove 4202 is stabilized, and the separation of the support block 4201 from the support groove 4202 or the offset of the support block 4201 is avoided, thereby avoiding affecting the position of the connecting rod 43 inside the connecting sleeve 42.

[0032] Working principle: After connecting the conductive copper busbar body 1 with connecting bolts 101 and connecting nuts 102, pull the connecting sleeve 42 and connecting rod 43, causing the connecting rod 43 and connecting sleeve 42 to move the sealing plate 31 through the bracket 41. Then slide the protective frame 2 so that the protective frame 2 is fitted onto the connection point of the conductive copper busbar body 1. Then release the connecting sleeve 42 and connecting rod 43, and the tension spring 33 drives the pull plate 32 to reset. The pull plate 32 drives the sealing plate 31 to reset, and the positioning block 3104 stabilizes the docking position of the sliding rod 3103 and the sliding groove 3102, so that the sliding rod 3103 stabilizes the position of the sealing plate 31 through the support plate 3101, so that the sealing plate 31 closes and protects. The gap between the frame 2 and the conductive copper busbar body 1 is slidably connected to the surface of the support rod 45 through the inner cavity of the connecting block 44, so that the connecting rod 43, the connecting sleeve 42 and the bracket 41 are rotatably connected. At the same time, the surface of the limiting block 4203 is slidably connected to the inner cavity of the limiting groove 4204 to stabilize the connection position of the support block 4201 and the support groove 4202, so that the surface of the connecting rod 43 is slidably connected to the inner cavity of the connecting sleeve 42, so that the connecting rod 43 and the connecting sleeve 42 will not affect the position of the sealing plate 31, thereby allowing the sealing plate 31 to adapt to gaps of different widths, so that the sealing plate 31, together with the protective frame 2, plays a protective role for the connection position of the conductive copper busbar body 1.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
