[0004] (ii) Technical solution.
[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution: A high-heat-dissipation dense busbar trunking includes a busbar trunking body, busbar connectors on both sides of the busbar trunking body, a protective component on the busbar trunking body, and a heat dissipation component at the bottom of the busbar trunking body. The protective assembly includes a housing fixedly installed on the upper part of the busbar trunking body. Two sliding rods are fixedly installed inside the housing, and two sliders are slidably connected between the two sliding rods. Two guide plates are fixedly installed on both sides of the busbar trunking body, and a surrounding plate is slidably connected between the two guide plates on the same side. Connecting plates are rotatably connected to both sides of the two sliders, and the two connecting plates on the same side are rotatably connected to the surrounding plate. Protective shells are fixedly installed on the opposite sides of the two surrounding plates. A bidirectional screw is rotatably connected inside the housing, and a handle is fixedly installed on one side of the bidirectional screw. The bidirectional screw is threadedly connected to the slider.
[0006] Furthermore, the protective shell has a U-shaped structure and is fitted onto the outside of the busbar trunking body.

[0011] 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.
[0012] Example like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an embodiment of the present invention proposes a high-heat-dissipation dense busbar trunking, including a busbar trunking body 1, busbar connectors 2 on both sides of the busbar trunking body 1, a protective component 3 on the busbar trunking body 1, and a heat dissipation component 4 at the bottom of the busbar trunking body 1. The protective component 3 protects the busbar connectors 2 from damage caused by falling or impacting foreign objects, improves the overall service life of the busbar trunking body 1, and facilitates the storage of the protective shell 39, making it easier to maintain the busbar connectors 2 and improving the flexibility of use. The heat dissipation component 4 dissipates heat from the busbar trunking body 1, preventing the resistance from increasing due to excessive temperature rise, thereby improving the current carrying capacity of the busbar trunking body 1, slowing down the insulation aging rate, and extending the service life of the busbar trunking. The protective assembly 3 includes a housing 31 fixedly installed on the upper part of the busbar trunking body 1. Two sliding rods 32 are fixedly installed inside the housing 31, and two sliders 33 are slidably connected between the two sliding rods 32. Two guide plates 37 are fixedly installed on both sides of the busbar trunking body 1. A surrounding plate 38 is slidably connected between the two guide plates 37 on the same side. Connecting plates 34 are rotatably connected to both sides of the two sliders 33, and the two connecting plates 34 on the same side are rotatably connected to the surrounding plate 38. Protective shells 39 are fixedly installed on the opposite sides of the two surrounding plates 38. A bidirectional screw 35 is rotatably connected inside the housing 31, and a handle 36 is fixedly installed on one side of the bidirectional screw 35. The bidirectional screw 35 is threadedly connected to the sliders 33. By rotating the handle 36, the bidirectional screw 35 is rotated, causing the sliders 33 to slide on the sliding rods 32. By rotating the connecting plate 34, the surrounding plate 38 slides on the guide plate 37 for guidance, thereby causing the two protective shells 39 to move away from or closer to each other. Thus, the protective shells 39 provide external protection for the busbar joint 2.
[0013] like Figure 3 As shown, in some embodiments, the protective shell 39 has a U-shaped structure and is fitted on the outside of the busbar trunking body 1; it is convenient to slide to the outside of the busbar connector 2 for protection.
[0014] like Figure 4 As shown, in some embodiments, the heat dissipation assembly 4 includes a heat-conducting plate 41 fixedly installed at the bottom of the bus trunking body 1, and heat dissipation fins 42 are provided at the bottom of the heat-conducting plate 41; the heat of the bus trunking body 1 is conducted out through the heat-conducting plate 41 and dissipated through the heat dissipation fins 42.
[0015] The wiring diagrams of the electrical components in this utility model are common knowledge in the field, and their working principles are known technologies. The appropriate model is selected according to actual use, so the control method and wiring layout will not be explained in detail.
[0016] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
