[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] This utility model protects the busbar joint by combining a first side plate and a second side plate, ensuring normal electrical conductivity. The mounting plate provides an installation environment for other components. When protecting the busbar joint, the worker first applies the first side plate to the joint. During application, the first side plate presses against a blocking block, causing the blocking block to move inwards onto the mounting plate. This movement of the blocking block moves a limiting rod and compresses a first spring. After the first side plate is in contact with the busbar joint, the groove aligns with the blocking block. The spring's return causes the blocking block to reset, entering the groove and securing the first side plate. The worker then installs the second side plate onto the first side plate, pressing against the sealing gasket for a tighter seal, thus protecting the joint. To remove the first side plate, the worker pulls a lever to move the blocking block, releasing the first side plate from its fixation. Attached Figure Description

[0020] 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 protection scope of the present utility model.

[0021] Example 1

[0022] like Figures 1-4 As shown, this utility model provides a technical solution: a busbar trunking with joint protection, including a busbar joint 1, an mounting plate 2 fixedly connected to the outer surface of the busbar joint 1, a first side plate 3 provided on the outer surface of the mounting plate 2, a pull rod 5 provided on the outer surface of the mounting plate 2, a limit rod 6 fixedly connected to the outer surface of the pull rod 5, a first spring 7 sleeved on the outer surface of the limit rod 6, a blocking block 8 fixedly connected to one end of the limit rod 6, a groove 9 provided on the outer surface of the first side plate 3, the groove 9 engaging with the blocking block 8, a sealing gasket 10 fixedly connected to the outer surface of the first side plate 3, and a second side plate 11 sleeved on the outer surface of the first side plate 3, the second side plate 11 slidingly connected to the first side plate 3.

[0023] In this embodiment, the busbar connector 1 is protected by the combination of the first side plate 3 and the second side plate 11, ensuring normal operation of the conductive work. The mounting plate 2 provides an installation environment for other components. When protecting the busbar connector 1, the worker first applies the first side plate 3 to the busbar connector 1. During application, the first side plate 3 presses against the blocking block 8, causing the blocking block 8 to move inward into the mounting plate 2. The movement of the blocking block 8 drives the limit rod 6 to move, and the blocking block 8 compresses the first spring 7. After the side plate 3 is attached to the busbar connector 1, the groove 9 will align with the blocking block 8. Then, the first spring 7 will push the blocking block 8 back to its original position, so that the blocking block 8 enters the interior of the groove 9, thus fixing the first side plate 3. Then, the worker will install the second side plate 11 on the first side plate 3. The second side plate 11 will squeeze the sealing gasket 10 to ensure a tighter seal, thereby protecting the connector. When it is necessary to disassemble the first side plate 3, the blocking block 8 will be moved by pulling the pull rod 5 to release the fixation of the first side plate 3.

[0024] Example 2

[0025] like Figures 1-4 As shown, a fixing frame 13 is fixedly connected to the outer surface of the first side plate 3. A moving rod 14 is sleeved on the inner wall of the fixing frame 13. The moving rod 14 is slidably connected to the fixing frame 13. A pull plate 4 is fixedly connected to one end of the moving rod 14. A locking block 16 is fixedly connected to one end of the moving rod 14. A locking hole 12 is opened on the outer surface of the second side plate 11. The locking hole 12 is engaged with the locking block 16. A second spring 15 is sleeved on the outer surface of the moving rod 14. One end of the second spring 15 is fixedly connected to the fixing frame 13. The other end of the second spring 15 is fixedly connected to the locking block 16.

[0026] In this embodiment, when the second side plate 11 is connected to the first side plate 3, the moving rod 14 is moved inside the fixing frame 13 by pulling the pull plate 4. The movement of the moving rod 14 causes the locking block 16 to move, and the second spring 15 is compressed at the same time as the locking block 16 moves. Then, the worker attaches the second side plate 11 to the bus connector 1 and squeezes the sealing gasket 10. After the second side plate 11 is attached, the locking hole 12 opened in the second side plate 11 will be directly above the locking block 16. Then, by releasing the pull plate 4, the second spring 15 will cause the locking block 16 to reset, so that the locking block 16 engages with the locking hole 12, thus completing the fixation of the second side plate 11.

[0027] Working principle:

[0028] like Figures 1-4As shown, in this utility model, during use, the operator first attaches the first side plate 3 to the busbar connector 1. During the attachment process, the first side plate 3 will press the blocking block 8, causing the blocking block 8 to move inward into the mounting plate 2. The movement of the blocking block 8 drives the limiting rod 6 to slide inside the mounting plate 2. At the same time, the blocking block 8 will compress the first spring 7. When the first side plate 3 and the busbar connector 1 are completely attached, the groove 9 of the first side plate 3 will align with the position of the blocking block 8. At this time, the first spring 7 is no longer under force. The rebound of the first spring 7 drives the blocking block 8 to reset, thereby allowing the blocking block 8 to enter the groove 9 and completing the fixation of the first side plate 3. Then, the operator puts the second side plate 11 onto the outer surface of the first side plate 3. During the movement of the second side plate 11, it will press the sealing gasket 10 to ensure a tighter seal. When connecting the second side plate 11 to the first side plate 3, the operator pulls the pull plate 4. The movement of the pull plate 4 drives the moving rod 14 to fix the first side plate 3. The internal sliding of the fixed frame 13 and the movement of the moving rod 14 drive the movement of the locking block 16. At the same time as the locking block 16 moves, the second spring 15 is compressed. When the second side plate 11 is attached to the bus joint 1, the locking hole 12 opened in the second side plate 11 will be directly above the locking block 16. At this time, the operator releases the pull plate 4, and the second spring 15 is no longer under force. The rebound of the second spring 15 drives the locking block 16 to reset, so that the locking block 16 enters the interior of the locking hole 12, completing the fixation of the second side plate 11 and thus protecting the joint. When it is necessary to disassemble the first side plate 3, the operator pulls the pull rod 5. The movement of the pull rod 5 drives the movement of the limiting rod 6. The movement of the limiting rod 6 drives the movement of the blocking block 8, so that the blocking block 8 leaves the interior of the groove 9, releasing the fixation of the first side plate 3. Then the operator pulls the pull plate 4 to drive the locking block 16 to move, so that the locking block 16 leaves the interior of the locking hole 12, and the second side plate 11 can be disassembled, thus facilitating the operator to inspect the bus joint 1.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
