[0032] 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.

[0033] Reference Figure 1 - Figure 5 The present invention provides an embodiment of a fire-resistant busbar trunking connection side plate, comprising two side plates 1 and a mounting plate 2. The side plates 1 are provided with multiple insertion slots 3, a fixing component is provided inside the side plates 1, and a shielding component is provided inside the side plates 1.

[0034] The fixing assembly includes a rotating rod 4, which is rotatably connected to the inside of the side plate 1. Two winding wheels 5 are fixedly connected to the outside of the side plate 1, and two winding ropes 6 are fixedly connected to the outside of the winding wheels 5. A baffle 9 is fixedly connected to the end of the winding rope 6 away from the winding wheels 5. A plug block 10 is fixedly connected to one side of the baffle 9 and to the other side of the baffle 9. A spring 8 is sleeved on the outside of the winding rope 6.

[0035] Specifically, the two side plates 1 form the main body of the connecting side plates, which cooperate with the mounting plate 2 to connect and protect the busbar groove. The insertion groove 3 in the side plate 1 is used to insert into the protrusion of the mounting plate 2 to achieve a fixed connection between the two. The rotating rod 4 is used to control the rotation of the winding wheel 5, thereby winding and unwinding the winding rope 6. The winding wheel 5 is used to wind or release the winding rope 6 under the drive of the rotating rod 4. The winding rope 6 is used to drive the baffle 9 to slide in the sliding groove 7 in the side plate 1. The spring 8 is used to push the baffle 9 to insert the insertion block 10 into the mounting plate 2 when the winding rope 6 is released; and to provide reverse resistance during disassembly. The baffle 9 is used to drive the insertion block 10 in and out of the protrusion of the mounting plate 2 under the action of the winding rope 6 and the spring 8 to achieve insertion and disassembly with the mounting plate 2. The insertion block 10 is used to cooperate with the protrusion of the mounting plate 2 to complete the connection and separation of the side plate 1 and the mounting plate 2.

[0036] Reference Figure 5 The shielding assembly includes an electromagnetic shielding layer 16, which is fixedly connected to the outside of the side plate 1. A base layer 17 is fixedly connected to one side of the electromagnetic shielding layer 16, and an insulating layer 15 is fixedly connected to the other side of the electromagnetic shielding layer 16. A fire-resistant layer 14 is fixedly connected to the outside of the insulating layer 15, and a heat-conducting layer 13 is fixedly connected to the outside of the fire-resistant layer 14.

[0037] Specifically, the electromagnetic shielding layer 16 is used to shield the electromagnetic field generated inside the busbar trunking to prevent electromagnetic interference to external equipment. The base layer 17 is fixed to one side of the electromagnetic shielding layer 16 to provide basic structural support for the entire connecting side plate, ensuring that it has sufficient strength and stability. The insulation layer 15 is used to prevent current leakage inside the busbar trunking to ensure the safety of personnel and equipment. The fire-resistant layer 14 is used to effectively resist high temperatures in the event of a fire and extend the safe operating time of the busbar trunking in a fire environment. The heat-conducting layer 13 is used to conduct away the heat generated when the busbar trunking is working, maintain the normal operating temperature of the busbar trunking, and ensure its stable operation.

[0038] Reference Figure 1 - Figure 5 The side plate 1 has multiple sliding grooves 7 inside. The outer side of the baffle 9 is slidably connected to the inner wall of the sliding groove 7. One end of the spring 8 is fixedly connected to the inner wall of the sliding groove 7, and the other end of the spring 8 is fixedly connected to the outer side of the baffle 9. The outer side of the plug block 10 is slidably connected to the inside of the side plate 1, and the outer side of the plug block 10 is inserted into the inner wall of the mounting plate 2. The side plate 1 has two winding grooves 12 inside. The outer side of the winding wheel 5 is fixedly connected to a rotating block 11. The outer sides of the heat-conducting layer 13, the fire-resistant layer 14, and the base layer 17 are all set inside the side plate 1. The electromagnetic shielding layer 16 is a metal shielding mesh.

[0039] Specifically, the chute 7 provides a sliding track for the baffle 9, allowing it to move smoothly within the side plate 1. Under the action of the winding rope 6 and the spring 8, the baffle 9 drives the insertion block 10 along the chute 7 to move in and out of the side plate 1, enabling connection and separation with the insertion slot 3 on the mounting plate 2. The spring 8 provides elasticity when the winding rope 6 is released, pushing the baffle 9 outwards so that the insertion block 10 is inserted into the mounting plate 2, thus fixing the side plate 1 to the mounting plate 2. During disassembly, this elasticity is overcome, providing reverse resistance for the retraction of the baffle 9 and the insertion block 10. The insertion block 10 cooperates with the insertion slot 3 on the side plate 1 to achieve quick connection and disassembly between the side plate 1 and the mounting plate 2, ensuring the connection of the fire-resistant busbar trunking. The installation and maintenance of the side panels proceeded smoothly. The winding groove 12 is used to accommodate the winding wheel 5, and the rotating block 11 is used to facilitate the operator to rotate the winding wheel 5, thereby controlling the winding and unwinding of the winding rope 6, and further controlling the position of the baffle 9 and the plug-in block 10. The heat-conducting layer 13 is used to conduct away the heat generated during the operation of the busbar trunking and maintain the normal operating temperature of the busbar trunking. The fire-resistant layer 14 is used to effectively resist high temperatures in the event of a fire and extend the safe operating time of the busbar trunking in a fire environment. The base layer 17 provides the basic structural support for the entire connecting side panel, ensuring that it has sufficient strength and stability. The electromagnetic shielding layer 16 uses a metal shielding mesh to shield the electromagnetic field generated inside the busbar trunking and prevent electromagnetic interference to external equipment.

[0040] Working principle: When it is necessary to connect the side plate 1 to the mounting plate 2, rotate the rotating rod 4. The rotating rod 4 drives the outer fixedly connected winding wheel 5 to rotate. The rotation of the winding wheel 5 will wind up the winding rope 6, which in turn drives the baffle 9 to compress the spring 8 until the plug block 10 is completely disengaged from the mounting plate 2. At this time, align the two mounting plates 2 with the plug slots 3 of the side plate 1 and insert them. Then release the rotating rod 4. Under the elastic force of the spring 8, the baffle 9 will slide outward along the slide groove 7, thereby driving the plug block 10 to move outward until the outer side of the plug block 10 is inserted into the mounting plate 2, realizing the fixed connection between the side plate 1 and the mounting plate 2. When it is necessary to disassemble, rotate the rotating rod 4. The rotating rod 4 drives the outer fixedly connected winding wheel 5 to rotate. The rotation of the winding wheel 5 will wind up the winding rope 6, which in turn drives the baffle 9 to compress the spring 8 until the plug block 10 is completely disengaged from the mounting plate 2. This realizes the convenient installation and disassembly of the side plate 1 and the mounting plate 2, so as to facilitate the maintenance and repair of the busbar trunking.

[0041] The electromagnetic shielding layer 16 is fixed inside the side plate 1, effectively shielding the electromagnetic field generated inside the busbar trunking and preventing electromagnetic interference to external equipment. One side of the electromagnetic shielding layer 16 is connected to the base layer 17, which provides structural support for the entire connecting side plate; the other side is connected to the insulation layer 15, which prevents current leakage inside the busbar trunking, ensuring the safety of personnel and equipment. Outside the insulation layer 15 is a fire-resistant layer 14, which effectively resists high temperatures in the event of a fire, extending the safe operating time of the busbar trunking. The outermost heat-conducting layer 13 is responsible for conducting away the heat generated during the operation of the busbar trunking, ensuring its normal operation.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
