[0018] 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.

[0019] This utility model provides a busbar trunking housing that facilitates heat dissipation, such as... Figure 1 , Figure 2 and Figure 5 As shown, it includes a base 1 and a top cover 2. The bottom of the top cover 2 is fixedly connected to an insert 3. The base 1 has a slot 4 and a fixing mechanism is provided on one side of the base 1.

[0020] The fixing mechanism includes a limiting frame 5, one side of the limiting frame 5 is fixedly connected to one side of the base 1, one side of the base 1 is fixedly connected to a mounting plate 6, a pull rod 7 is slidably connected to the upper part of the mounting plate 6, a movable plate 8 is slidably connected to the side surface of the pull rod 7, one side of the movable plate 8 is fixedly connected to an insert block 9, and the other side of the movable plate 8 is fixedly connected to a first spring 10. The inner cavity of the limiting frame 5 is connected to the slot 4, and the end of the first spring 10 away from the movable plate 8 is fixedly connected to one side of the mounting plate 6.

[0021] The insert 3 has a socket that matches the insert block 9. The insert 3 is inserted into both the slot 4 and the limiting frame 5. The insert block 9 extends into the limiting frame 5 and is inserted into the socket.

[0022] When the top cover 2 is installed on the top of the base 1, the insert strip 3 needs to be inserted into the slot 4 and the limiting frame 5. When the insert strip 3 enters the limiting frame 5, it will contact the arc surface of the insert block 9 and squeeze the insert block 9, causing the insert block 9 to retract. When the insert block 9 retracts, the moving plate 8 can slide synchronously, thereby compressing the first spring 10. When the top cover 2 is installed in place, the insertion hole on the insert strip 3 is just aligned with the insert block 9. At this time, the first spring 10 will release the pressure and push the moving plate 8 to move, thereby driving the insert block 9 to be stably inserted into the insertion hole and locking the insert strip 3, thus effectively improving the stability of the top cover 2 after it is installed on the base 1.

[0023] Furthermore, in order to allow the upper cover 2 to be separated from the base 1, such as... Figure 1 , Figure 3 and Figure 5 As shown, a pull plate 13 is fixedly connected to one end of the pull rod 7, and a limit ring 11 and a magnetic ring 12 are fixedly connected to the side surface of the pull rod 7 respectively. One side of the limit ring 11 is in contact with the side of the moving plate 8 near the insert block 9, and one side of the magnetic ring 12 is in contact with the side of the mounting plate 6 away from the first spring 10.

[0024] In the initial state, the magnetic ring 12 can be attracted to the mounting plate 6, which effectively ensures the stability of the pull rod 7. When removing the top cover 2, the staff can pull the pull rod 7 through the pull plate 13. When the pull rod 7 moves, the limiting ring 11 will drive the moving plate 8 to move. When the moving plate 8 moves, it can drive the insert 9 to move out of the insertion hole, thereby releasing the restriction on the insert 3. Then the staff can remove the top cover 2.

[0025] Furthermore, to facilitate heat dissipation from the busbar casing, such as Figure 1 , Figure 2 and Figure 3 As shown, an insulating partition 14 is fixedly connected inside the base 1, a heat sink 15 is fixedly connected to the bottom of the base 1, the inner cavity of the heat sink 15 is connected to the inner cavity of the base 1, a cooling fan 16 is fixedly connected inside the heat sink 15, and a filter plate 17 is fixedly connected to the bottom of the heat sink 15.

[0026] A connecting frame 18 is fixedly connected to the top of the cover 2. The inner cavity of the connecting frame 18 is connected to the inner cavity of the base 1. A top plate 19 is fixedly connected to the top of the connecting frame 18. Several ventilation holes are provided on the connecting frame 18.

[0027] The filter plate 17 can effectively block external dust and debris from entering the inner cavity of the base 1, ensuring the cleanliness and safety of the inside of the busbar trunking. When the cooling fan 16 is working, it can draw out the hot air in the inner cavity of the base 1, thereby expelling the hot air to the external environment, effectively reducing the temperature inside the busbar trunking. At the same time, the vent holes on the connecting frame 18 ensure air circulation, further accelerating heat dissipation and improving heat dissipation efficiency.

[0028] In order to facilitate the disassembly of the top cover 2 by staff, such as Figure 1 , Figure 3 and Figure 4 As shown, a push plate 21 is slidably connected inside the slot 4, and a second spring 20 is fixedly connected to the bottom of the push plate 21. The bottom end of the second spring 20 is fixedly connected to the bottom inner wall of the slot 4, and the top of the push plate 21 is in contact with the bottom of the insert 3.

[0029] When the insert 3 is inserted into the slot 4, it will come into contact with the push plate 21 and squeeze the push plate 21, causing the push plate 21 to move downward inside the slot 4, thereby compressing the second spring 20. When the operator removes the top cover 2, after the insert 9 is moved out of the socket, the second spring 20 will release the pressure and can drive the insert 3 and the top cover 2 to move upward through the push plate 21, thereby causing the insert 9 to be misaligned with the socket, so that the operator can remove the top cover 2.

[0030] It should be noted that, in order to improve the stability of the busbar trunking casing, such as... Figure 1 , Figure 2 and Figure 3 As shown, a bracket 22 is fixedly connected to the bottom of the base 1, and a connection hole is provided at the top of the bracket 22.

[0031] When in use, the base 1 can be installed in a preset position by means of the bracket 22. The bracket 22 is provided with a connection hole, and bolts can be used to fix the bracket 22 through the connection hole, thereby effectively improving the stability of the busbar trunking housing.

[0032] Working principle: When the top cover 2 is installed on the base 1, the insert 3 needs to be inserted into the slot 4 and the limiting frame 5. When the insert 3 enters the limiting frame 5, it will contact the arc surface of the insert 9 and squeeze the insert 9, causing the insert 9 to retract. When the insert 9 retracts, the moving plate 8 can slide synchronously, thereby compressing the first spring 10. At the same time, the insert 3 will also contact the push plate 21 and squeeze the push plate 21, causing the push plate 21 to move downward inside the slot 4, thereby compressing the second spring 20. When the top cover 2 is installed in place, the insertion hole on the insert 3 is just aligned with the insert 9. At this time, the first spring 10 will release pressure and push the moving plate 8 to move, thereby driving the insert 9 to be stably inserted into the insertion hole. Inside, the insert 3 is locked. During use, the cooling fan 16 can draw out the hot air from the inner cavity of the base 1. The vent on the connecting frame 18 ensures air circulation, thereby expelling the hot air to the outside environment. When separating the top cover 2 from the base 1, the operator can pull the pull rod 7 through the pull plate 13. When the pull rod 7 moves, the limiting ring 11 will drive the moving plate 8 to move. When the moving plate 8 moves, it can drive the insert block 9 to move out of the socket, thereby releasing the restriction on the insert 3. When the insert block 9 moves out of the socket, the second spring 20 will release the pressure and can drive the insert 3 and the top cover 2 to move upward through the push plate 21, thereby causing the insert block 9 to be misaligned with the socket. Then the operator can directly remove the top cover 2.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
