[0002] Enclosed busbar trunking is a completely enclosed busbar system with a metal shell, such as steel plate or aluminum alloy. It contains conductive busbars of copper or aluminum, separated by insulating materials, and is used to transmit high-current electrical energy. Its core function is to replace traditional cables in industrial, commercial, and high-rise building scenarios, achieving efficient power transmission and distribution. Suitable for high-current applications, it offers advantages such as high reliability, convenient installation, and easy maintenance. Enclosed busbar trunking mainly consists of conductive busbars, connectors, a shell, and sealing plates. The enclosure created by the connectors directly affects the stability and safety of the enclosed busbar trunking's connection operation.

[0003] In related technologies, during the use of enclosed busbar trunking, the joints of the connected enclosed busbar trunking are generally surrounded and sealed by top, bottom and left and right sealing plates, thereby protecting the joints before use.

[0004] However, in the current use of enclosed busbar trunking, the installation of the upper and lower sealing plates requires multiple bolts, and the sealing plates are installed on the outside of the enclosed busbar trunking joints. This makes it inconvenient to connect and surround the enclosed busbar trunking, affecting the convenience and efficiency of connecting and surrounding the enclosed busbar trunking.

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1-4This utility model provides a technical solution: a closed busbar trunking, including a busbar trunking 1 and a connecting and surrounding mechanism. Connectors 2 are installed on both sides of the busbar trunking 1. Side sealing plates 3 located outside the connectors 2 are installed on the front and rear sides of both sides of the busbar trunking 1. After the connectors 2 are connected to the busbar trunking 1, a fully enclosing and sealing medium is formed on the outside of the connection between the busbar trunking 1 and the connectors 2. The operation only requires vertical alignment and tightening, avoiding the need for separate vertical and horizontal bolt installation of the connectors 2 during the sealing process. Therefore, the convenience and operational efficiency of connecting and sealing the busbar trunking 1 and the connectors 2 are improved.

[0031] Reference Figures 1-4 In a preferred embodiment, the connecting enclosure mechanism includes an enclosure seat 4, which is movably connected to both sides of the bottom left side of the busbar trough 1. An enclosure frame 5 is movably connected to the top of the enclosure seat 4, and an enclosure plate 6 is movably connected to the inner side of the enclosure seat 4. An enclosure piece 7 is movably connected to the inner side of the enclosure frame 5. Enclosure widening mechanisms are respectively arranged on both sides of the enclosure plate 6 and the enclosure piece 7. After the connector 2 connects the two busbar troughs 1, the enclosure plate 6 and the enclosure piece 7 are held and moved to the upper and lower positions of the connector 2, and then the enclosure frame 5 and the enclosure seat 4 are moved inward to mate the enclosure seat 4 and the enclosure frame 5 on the outside of the connector 2, so that the enclosure seat 4 and the enclosure frame 5 are connected. The frame 5, together with the surrounding plate 6 and the surrounding piece 7, performs the work of surrounding and sealing the joint 2. The surrounding and widening mechanism includes a widening groove 8, a widening plate 9, and a widening opening 10. The widening groove 8 is respectively opened on both sides of the surrounding plate 6 and the surrounding piece 7. The widening plate 9 is movably connected inside the widening groove 8. The outer side of the widening plate 9 is fixedly connected to the inner side of the surrounding seat 4 and the surrounding frame 5 respectively. The widening opening 10 is opened on the top of the widening plate 9. The surrounding plate 6 and the surrounding piece 7 can be used to widen the connection between the surrounding seat 4 and the surrounding frame 5, so that the user can adjust the surrounding width between the surrounding seat 4 and the surrounding frame 5 according to the actual use needs, thus improving the usability of the surrounding seat 4 and the surrounding frame 5.

[0032] Reference Figures 2-4 In a preferred embodiment, screw cylinders 11 connected to the widening opening 10 are fixedly connected to both sides of the outer side of the surrounding plate 6 and the surrounding piece 7. The screw cylinders 11 are internally threaded with bolts 12 located inside the widening opening 10. The widening opening 10 can prevent the widening plate 9 from detaching from the widening groove 8 during operation, thus providing stability for the widening plate 9. The top of the surrounding base 4 is provided with a lifting groove 13, and the bottom of the surrounding frame 5 is located inside the lifting groove 13, which can provide space for the surrounding frame 5 to dock and lift with the surrounding base 4, thus improving the docking flexibility of the surrounding frame 5 and the surrounding base 4.

[0033] Reference Figures 2-4In a preferred embodiment, a fixing port 14 communicating with the lifting groove 13 is provided on the top of the outer side of the enclosure seat 4. A fixing plate 15 is movably connected inside the fixing port 14, which can be used to tighten and fix the enclosure seat 4 and the enclosure frame 5, avoiding the situation where it is difficult to connect and fix the enclosure seat 4 and the enclosure frame 5. Therefore, the convenience of connecting and fixing the enclosure seat 4 and the enclosure frame 5 is improved. A fixing pad 16 is movably connected inside the fixing port 14. The outer side of the fixing pad 16 is fixedly connected to the inner side of the fixing plate 15, which can fix and prevent slippage between the fixing plate 15 and the enclosure frame 5, thus improving the fixing stability of the fixing plate 15.

[0034] Reference Figures 2-4 In a preferred embodiment, a screw sleeve 17 communicating with a fixing port 14 is fixedly connected to the top of the outer side of the surrounding seat 4. A screw rod 18 is threadedly connected to the inside of the screw sleeve 17. The inner side of the screw rod 18 is fixedly connected to the outer side of the fixing plate 15. This provides a medium for the user to apply a clamping force to the fixing plate 15, avoiding the situation where it is difficult to apply force to fix the fixing plate 15 during use. Therefore, the ease of applying force to fix the fixing plate 15 is improved. The inner side of the screw sleeve 17 is provided with a movable groove 19 communicating with the fixing port 14. The outer side of the fixing plate 15 is located inside the movable groove 19, which provides the fixing plate 15 with a space for back and forth movement. This avoids the situation where the fixing plate 15 is difficult to move back and forth during the application of force by the screw rod 18. Therefore, the smoothness of operation of the fixing plate 15 is improved.

[0035] Specifically, the working process or principle of this enclosed busbar trunking is as follows: During use, after the busbar trunking 1 is connected via connector 2, the surrounding plate 6 and surrounding piece 7 are held and moved to the upper and lower positions of connector 2. Then, the surrounding piece 7 and surrounding plate 6 move the surrounding frame 5 and surrounding seat 4 inwards, allowing the bottom of the surrounding frame 5 to enter the lifting groove 13 for docking. Subsequently, according to the actual width requirement of the busbar trunking 1 and connector 2 enclosure, the surrounding seat 4 is held and moved towards the busbar trunking 1 via the lifting groove 13, causing the inner sides of the surrounding frame 5 and surrounding seat 4 to contact the surface of the busbar trunking 1. At this time, the widening plate 9 moves along with the surrounding seat 4 and surrounding frame 5 inside the widening groove 8. During the expansion and adjustment process, the expansion connection between the enclosure seat 4 and the enclosure plate 6, and between the enclosure frame 5 and the enclosure piece 7, is expanded. At the same time, the inner side of the bolt 12 moves inside the widening opening 10 to engage with the screw cylinder 11, and moves between the widening plate 9 and the widening groove 8 to prevent them from detaching. Then, the hand-held screw 18 is rotated to engage with the screw sleeve 17 to apply an inward threaded thrust to the fixing plate 15, so that the fixing plate 15 drives the fixing pad 16 to contact and press against the surface of the enclosure frame 5, and presses and fixes the enclosure frame 5 and the enclosure seat 4. The enclosure frame 5 and the enclosure seat 4, together with the enclosure plate 6 and the enclosure piece 7, are clamped and fixed on the outside of the busbar trough 1 and the joint 2, forming a protective medium that fully surrounds and seals the outside of the joint 2, and performing a surrounding and sealing operation between the connected joints 2.

[0036] It should be noted that busbar 1, connector 2 and side sealing plate 3 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
