[0002] The busbar joint silicone protective box is a device used in electrical equipment, especially at the busbar connection, to provide insulation protection and sealing. It not only provides comprehensive insulation and mechanical protection, but also significantly improves safety and corrosion and rust prevention capabilities, ensuring the stable operation of the power system.

[0003] When the existing protection box needs maintenance on the busbar joint, it must be removed from the outside of the busbar joint. After the busbar joint is repaired, the removed protection box must be reinstalled in its original position. In this process, not only must the removed protection box be stored properly, but it must also be repositioned and installed on the outside of the busbar joint, which increases the cumbersomeness of busbar joint maintenance. Therefore, a high-temperature resistant silicone protection box for busbar joints is needed to quickly open the protection box and position it at the bottom of the busbar joint, making it easy to put the protection box back in place and reducing the cumbersomeness of busbar joint maintenance. Utility Model Content

[0004] The purpose of this utility model is to provide a high-temperature resistant silicone protective box for busbar joints, in order to solve the problem mentioned in the background art, where existing protective boxes require the protective box to be removed from the outside of the busbar joint when maintenance is needed, and then reinstalled in its original position after the maintenance. This process not only requires storing the removed protective box properly, but also repositioning and reinstalling it outside the busbar joint, which increases the complexity of busbar joint maintenance.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a high-temperature resistant silicone protective box for busbar connectors, comprising:

[0007] The protective box body and the guide assembly are located at the bottom of the protective box body;

[0008] The guiding assembly includes a first connecting block, a second connecting block, a limiting post, a guide plate, a connecting hole, a limiting groove, and a limiting block; the first connecting block is fixed to the upper surface of the protective box body, the second connecting block is fixed to the lower surface of the protective box body, the limiting post is connected through the interior of the second connecting block, the guide plate is fixed to the outer surface of the limiting post, the connecting hole is opened inside the guide plate, the limiting groove is opened inside the guide plate, the limiting groove is not opened through the interior of the guide plate, and the limiting block has the same shape as the connecting hole.

[0009] Furthermore, a fixing plate is fixed to the outer surface of the second connecting block, a fixing tube is fixed to the outer surface of the fixing plate, and a first spring is fixed inside the fixing tube.

[0010] Furthermore, a connecting post is fixed to the outer surface of the first spring, the connecting post and the limiting block are rotatably connected, and a guide post is fixed to the outer surface of the connecting post.

[0011] Furthermore, it also includes a limiting component, which includes a fixed frame, a movable groove, a movable column, a guide rod, and a silicone column; the fixed frame is fixed to the lower surface of the second connecting block, the movable groove is opened inside the fixed frame, the movable column is slidably connected to the inside of the movable groove, the guide rod is fixed to the outer surface of the bottom end of the movable column and is connected through the inside of the fixed frame, and the silicone column is fixed to the upper surface of the movable column and is connected through the inside of the limiting column.

[0012] Furthermore, a mounting tube is fixed to the outer surface of the fixing frame, and a second spring is fixed inside the mounting tube.

[0013] Furthermore, a connecting plate is fixed to the outer surface of the second spring, and a fixing rod is fixed to the outer surface of the connecting plate, with the fixing rod penetrating and connecting to the inside of the guide rod.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through the set guide component, when the busbar connector needs to be repaired, firstly, the protective box body is opened, so that the first connecting block and the second connecting block are on the same horizontal line. A pushing force is applied to the guide plate, and after the limiting post passes through the inside of the first connecting block, a pulling force is applied to the guide post, which drives the limiting block and the connecting post to pass through the connecting hole. A rotational force is applied to the limiting block, so that the limiting block is consistent with the shape of the limiting groove. The force applied to the guide post is removed, and under the elastic force of the first spring, the limiting block is stuck inside the guide plate, thus exposing the busbar connector for repair. This solution quickly opens the protective box and positions it at the bottom of the busbar connector, making it easy to return the protective box to its original position. This reduces the cumbersomeness of repairing the busbar connector. In addition, the addition of alumina inside the protective box body improves the high temperature resistance and thermal conductivity of the silicone protective box.

[0016] Second, based on the first beneficial effect, when the limit post needs to be pushed to the required position, a pushing force is applied to the connecting plate to drive the fixed rod out of the guide rod. Then, a downward pressing force is applied to the guide rod to drive the movable post back into the movable groove, thereby driving the silicone post out of the limit post. This solution can quickly complete the locking and releasing of the limit post. Attached Figure Description

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0029] Please see Figures 1-3As shown, this embodiment is a high-temperature resistant busbar connector silicone protective box, comprising:

[0030] The protective box body 11 and the guide assembly are located at the bottom of the protective box body 11.

[0031] The inner surface of the protective box body 11 is attached to the lower surface of the bus connector. When the protective box body 11 is opened, it can still be restricted to the required position.

[0032] The guide assembly includes a first connecting block 21, a second connecting block 22, a limiting post 23, a guide plate 24, a connecting hole 25, a limiting groove 26, and a limiting block 292. The first connecting block 21 is fixed to the upper surface of the protective box body 11, the second connecting block 22 is fixed to the lower surface of the protective box body 11, the limiting post 23 is connected through the interior of the second connecting block 22, the guide plate 24 is fixed to the outer surface of the limiting post 23, the connecting hole 25 is opened inside the guide plate 24, the limiting groove 26 is opened inside the guide plate 24, the limiting groove 26 is not opened through the interior of the guide plate 24, and the limiting block 292 has the same shape as the connecting hole 25.

[0033] By passing the limiting post 23 through the interior of the first connecting block 21 and the second connecting block 22, the protective box body 11 can be restricted to an open state. The guide plate 24 is used to pull and push the limiting post 23 to the desired position. The connecting hole 25 is used to allow the limiting block 292 to pass through the interior of the guide plate 24, and the limiting groove 26 is used to restrict the limiting block 292 inside the guide plate 24.

[0034] A fixing plate 27 is fixed to the outer surface of the second connecting block 22, a fixing tube 28 is fixed to the outer surface of the fixing plate 27, and a first spring 29 is fixed inside the fixing tube 28.

[0035] The fixing plate 27 is used to support and install the second connecting block 22, and then to support and install the fixing tube 28. The fixing tube 28 is used to support and install the first spring 29. The first spring 29 is used to drive the limiting block 292 to return to its original position, thereby restricting the limiting block 292 inside the guide plate 24.

[0036] A connecting post 291 is fixed on the outer surface of the first spring 29. The connecting post 291 is rotatably connected to the limiting block 292. A guide post 293 is fixed on the outer surface of the connecting post 291.

[0037] The connecting post 291 is used to support and install the first spring 29, and then support and install the limiting block 292, while the guide post 293 facilitates pulling the limiting block 292 out of the guide plate 24.

[0038] Working principle: When the busbar connector needs to be repaired, first open the protective box body 11 so that the first connecting block 21 and the second connecting block 22 are on the same horizontal line. Apply a pushing force to the guide plate 24. After the limiting post 23 passes through the inside of the first connecting block 21, apply a pulling force to the guide post 293. After the limiting block 292 and the connecting post 291 pass through the connecting hole 25, apply a rotational force to the limiting block 292 so that the limiting block 292 is consistent with the shape of the limiting groove 26. Remove the force applied to the guide post 293. Under the elastic force of the first spring 29, the limiting block 292 is stuck inside the guide plate 24, and the busbar connector can be exposed for repair.

[0039] This step quickly opens the protection box and positions it at the bottom of the busbar connector, making it easy to return the protection box to its original position. This reduces the complexity of repairing the busbar connector. In addition, aluminum oxide is added inside the protection box body 11, which improves the high temperature resistance and thermal conductivity of the silicone protection box.

[0040] Please see Figure 1 , Figure 2 and Figure 4 As shown, this embodiment, based on the above embodiment, further includes a limiting component. The limiting component includes a fixed frame 31, a movable groove 32, a movable column 33, a guide rod 34, and a silicone column 35. The fixed frame 31 is fixed to the lower surface of the second connecting block 22. The movable groove 32 is opened inside the fixed frame 31. The movable column 33 is slidably connected to the inside of the movable groove 32. The guide rod 34 is fixed to the outer surface of the bottom end of the movable column 33 and passes through the inside of the fixed frame 31. The silicone column 35 is fixed to the upper surface of the movable column 33 and passes through the inside of the limiting column 23.

[0041] The fixed frame 31 provides an installation base for the movable slot 32 and the movable column 33, ensuring that the entire limiting assembly is stably installed under the protective box. The movable slot 32 is used for the movable column 33 to move inside it. The movable column 33 is used to change the position of the silicone column 35. The guide rod 34 facilitates changing the position of the movable column 33. The silicone column 35 is used to limit the limiting column 23 to the required position.

[0042] A mounting tube 36 is fixed to the outer surface of the mounting bracket 31, and a second spring 37 is fixed inside the mounting tube 36.

[0043] The mounting tube 36 is used to support and install the fixing bracket 31, and then support and install the second spring 37. The second spring 37 is used to spring the connecting plate 38 back to its original position, and then spring the fixing rod 39 back into the guide rod 34.

[0044] A connecting plate 38 is fixed to the outer surface of the second spring 37, and a fixing rod 39 is fixed to the outer surface of the connecting plate 38. The fixing rod 39 passes through and connects to the inside of the guide rod 34.

[0045] The connecting plate 38 is used to change the position of the fixing rod 39, which in turn is used to limit the guide rod 34 to the required height.

[0046] Working principle: When it is necessary to push the limiting post 23 to the required position, a pushing force is applied to the connecting plate 38, which causes the fixed rod 39 to disengage from the guide rod 34. Then, a downward pressing force is applied to the guide rod 34, which causes the movable post 33 to retract into the movable groove 32, thereby causing the silicone post 35 to disengage from the limiting post 23.

[0047] This step allows for the quick locking and releasing of the limit post 23.
