Description

Technical Field

[0001] This utility model relates to the field of busbar technology, and in particular to a dense insulated busbar connection box. Background Technology

[0002] A plug-in box is an assembly used for the installation and wiring of electrical and electronic equipment. It typically provides a centralized location for plugging in and connecting multiple electrical devices or cables. Plug-in boxes are widely used in various equipment, buildings, and power systems, especially in industrial, construction, transportation, and communication fields. To effectively prevent electrical faults such as electric shock and short circuits, they are particularly suitable for high-voltage, high-current power distribution systems, thus requiring the use of densely insulated busbar plug-in boxes.

[0003] Compact insulated busbar trunking junction boxes can be divided into several types, including internal junction boxes, exposed junction boxes, and horizontally installed junction boxes. The variety of types allows users to choose the appropriate type based on specific application scenarios and power requirements. Exposed junction boxes expose the busbar trunking to the outside, making them suitable for installation in relatively open areas, facilitating the connection and inspection of electrical equipment. They are typically used for electrical connections between equipment and are suitable for environments with high space and frequency requirements.

[0004] In traditional busbar junction box designs, the connection between the busbar trunking and electrical equipment often relies solely on friction and simple mechanical connections to maintain stability. Especially during the connection process, cables are prone to tangling due to lack of organization, affecting the convenience of later maintenance. This often fails to provide sufficient connection strength, particularly in high-current transmission applications, easily leading to poor contact or loosening, increasing electrical risks. Therefore, ensuring the stability and reliability of busbar junction boxes in practical applications has become an urgent problem to be solved. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a dense insulated busbar trunking plug-in box, which aims to improve the problem that cables are messy and inconvenient for future maintenance if they are not organized after being connected in the plug-in box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dense insulated busbar trunking plug-in box, including a box body, a fixing rod fixedly connected inside the box body, a positioning groove being opened inside the fixing rod, and an installation component being provided on one side of the fixing rod;

[0007] The installation assembly includes an installation plate with one side attached to the outer wall of a fixed rod, a locking block fixedly connected to the outer wall of the fixed rod, a buckle fixedly connected to the outer wall of the installation plate, the buckle engaging with the locking block, a telescopic rod fixedly connected to one side of the installation plate, a clamp fixedly connected to one end of the telescopic rod, the clamp slidingly connected inside a positioning groove, and a reset assembly provided on the outer wall of the telescopic rod.

[0008] As a further description of the above technical solution:

[0009] The reset assembly includes a spring, which is sleeved on the outer wall of the telescopic rod. One end of the spring is fixedly connected to the outer wall of the clamping plate, and the other end of the spring is fixedly connected to one side of the mounting plate.

[0010] As a further description of the above technical solution:

[0011] A connecting column one is fixedly connected inside the box body. A connecting plate one is fixedly connected to one end of the connecting column one, and a connecting plate two is fixedly connected to one end of the connecting column one.

[0012] As a further description of the above technical solution:

[0013] One end of the first connecting post is provided with a second connecting post, and one end of the second connecting post is fixedly connected with a second contact plate.

[0014] As a further description of the above technical solution:

[0015] The second contact plate is slidably connected between the first connecting plate and the second contact plate. The third locking block is fixedly connected to the outer wall of the second contact plate. The second locking block is fixedly connected to one side of the first connecting plate. The third locking block is engaged with the second locking block.

[0016] As a further description of the above technical solution:

[0017] One end of the second connecting column is fixedly connected to a first contact plate, and the first contact plate is slidably connected between the first connecting plate and the second connecting plate.

[0018] As a further description of the above technical solution:

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the cable is first placed inside the positioning groove, and the mounting plate is connected to the clamp by a buckle. The tension of the spring supports the clamp plate, which achieves the effect of limiting the cable. This solves the problem that the cable is messy if it is not organized after being connected in the socket box, which makes it inconvenient for future maintenance, and improves the practicality of the socket box.

[0024] 2. In this utility model, the locking block three on the outer wall of the second contact plate engages with the second locking block to prevent separation. The first contact plate is inserted between the first connecting plate and the second connecting plate to further increase the contact area. Then, the bolts are inserted into the first connecting plate, the first contact plate and the second contact plate, thereby improving the connection strength of the busbar trunking. This solves the problem that the traditional busbar trunking has poor connection strength due to only friction connection and then insulation through the insulating sleeve, and improves the connection strength of the dense insulated busbar trunking plug-in box.

[0030] 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.

[0031] Reference Figure 1 and Figure 2This utility model provides an embodiment of a dense insulated busbar trunking plug-in box, comprising a box body 1, a fixing rod 2 fixedly connected inside the box body 1, a positioning groove 4 formed inside the fixing rod 2, and an installation component provided on one side of the fixing rod 2. The fixing rod 2 serves as a support structure, ensuring the stability of the entire installation component, allowing each connecting part to be precisely aligned and firmly fixed. The positioning groove 4 allows for accurate positioning of cables and connectors during assembly, preventing deviations.

[0032] The mounting assembly includes a mounting plate 6 that is attached to the outer wall of a fixing rod 2 on one side. A locking block 5 is fixedly connected to the outer wall of the fixing rod 2, and a buckle 7 is fixedly connected to the outer wall of the mounting plate 6. The engagement of the locking block 5 and the buckle 7 provides reliable fixation through a locking mechanism, ensuring the mounting plate 6 is securely connected to the fixing rod 2, preventing loosening or detachment, and ensuring the safety and stability of the connector box during use. A telescopic rod 8 is fixedly connected to one side of the mounting plate 6, and a clamping plate 10 is fixedly connected to one end of the telescopic rod 8. The clamping plate 10 precisely positions the connecting cable, allowing the connection end to be accurately inserted into the busbar system. The design of the telescopic rod 8 allows the clamping plate 10 to be adjusted as needed to accommodate connecting cables of different sizes and shapes. A reset assembly is provided on the outer wall of the telescopic rod 8, including a spring 9. The spring 9 is sleeved on the outer wall of the telescopic rod 8, with one end fixedly connected to the outer wall of the clamping plate 10 and the other end fixedly connected to one side of the mounting plate 6. The elasticity of the reset component ensures that the clamp 10 can quickly return to its initial position during installation and disassembly, preventing the clamp 10 from loosening or shifting when not in operation, thereby improving the convenience and safety of the installation process.

[0033] Specifically, during cable positioning and arrangement, the cables are first neatly placed inside the structure equipped with positioning grooves 4. Positioning grooves 4 precisely provide suitable space for the cables, ensuring they remain stably in their predetermined positions. Next, the clamping plate 10 is securely mounted on the fixing rod 2 via the mounting plate 6, ensuring the stability and reliability of the entire positioning device. The mounting plate 6 is engaged with the locking block 5 via buckles 7, forming a strong connection and ensuring the mounting plate 6 remains firmly in place during use. The mounting plate 6 and clamping plate 10 are connected via a telescopic rod 8, which has flexible adjustment capabilities, allowing for adjustments to the contact force and position of the clamping plate 10 according to actual needs, thus more precisely fixing the cables. Once the mounting plate 6 is in place, the spring 9 supports the clamping plate 10 through tension, ensuring the clamping plate 10 firmly adheres to the outer wall of the cable. This not only effectively prevents cable slippage but also avoids cable displacement due to external forces, thereby achieving precise cable positioning and arrangement. This design takes into full consideration the safety and neatness of the cables, making the entire cable management process more efficient and stable, while also improving the protection of the cables during the use of the equipment.

[0034] Reference Figure 3 Inside the housing 1, a connecting column 1 (3) is fixedly connected. One end of connecting column 1 (3) is fixedly connected to a connecting plate 11 (11), and the other end is fixedly connected to a connecting plate 2 (13). Connecting column 1 (3) serves as a support structure, providing a stable foundation for connecting plates 11 (11) and 2 (13), ensuring the components maintain correct alignment and stability during assembly. One end of connecting column 1 (3) is provided with a connecting column 2 (15), and one end of connecting column 2 (15) is fixedly connected to a contact plate 2 (17). The function of contact plate 2 (17) is to further enhance the stability of the connection and allow it to slide between connecting plates 11 (11) for fine-tuning and precise alignment during the connection process, ensuring optimal contact surface fit. A locking block 3 (18) is fixedly connected to the outer wall of contact plate 2 (17), engaging with locking block 2 (12). This locking structure ensures a secure connection between contact plate 2 (17) and connecting plate 11, preventing loosening or detachment during use and enhancing connection reliability. A locking block 12 is fixedly connected to one side of connecting plate 11. This design helps enhance the stability of the engagement, ensuring that locking block 12 can fit tightly with locking block 18, improving connection strength and preventing any displacement or gaps. A contact plate 16 is fixedly connected to one end of connecting post 15. Contact plate 16 is slidably connected between connecting plate 11 and connecting plate 13, allowing for flexible adjustment to adapt to different connection requirements and provide a stable contact area. The sliding connection design of contact plate 16 enables precise mating and maintains good contact, thereby effectively transmitting current and reducing contact resistance. Limiting plates 14 are fixedly connected to one side of both connecting plate 13 and contact plate 16. The function of limiting plates 14 is to prevent excessive displacement of contact plate 16 and contact plate 17, ensuring they always remain in the correct position, thereby improving the overall stability and reliability of the system and avoiding connection failures caused by displacement or misalignment. Bolts 19 are installed inside the connecting plate 11, contact plate 16, and contact plate 17, and nuts 20 are threaded onto the outer wall of the bolts 19. The use of bolts 19 ensures a tight connection between the various components, while nuts 20 further ensure the fixing of bolts 19. This not only improves the strength and stability of the entire structure, but also allows for precise adjustment and locking through nuts 20, thereby ensuring the long-term reliable operation of the device.

[0035] Specifically, when connecting post 2 15 is connected to connecting post 1 3, connecting post 2 15 is first inserted between connecting post 1 11 via contact plate 2 17. During the connection process, the locking block 3 18 on the outer wall of contact plate 2 17 is firmly engaged with locking block 2 12, effectively preventing any loosening or separation during the connection process. Contact plate 1 16 is further inserted between connecting post 1 11 and connecting post 2 13, thereby increasing the contact area and further improving the stability and conductivity of the electrical connection. To ensure the stability of the entire connection structure, bolts 19 are then inserted into the pre-set holes of connecting post 1 11, contact plate 1 16, and contact plate 2 17 to ensure that all components are tightly connected. Bolts 19 are then tightened with nuts 20, forming a reliable and robust electrical connection. This structural design effectively improves the connection strength and safety of the busbar system, ensures the stability of the connection during long-term high-current use, reduces the risk of poor contact and electrical faults, and thus optimizes the performance of the entire electrical system.

[0036] Working principle: When using this compact insulated busbar duct plug-in box, the cables are first positioned and arranged inside the positioning slot 4. Then, the clamping plate 10 is installed on the fixing rod 2 via the mounting plate 6. The mounting plate 6 is connected to the clamping block 5 via the buckle 7. The mounting plate 6 is connected to the clamping plate 10 via the telescopic rod 8. After the mounting plate 6 is installed in place, the tension of the spring 9 supports the clamping plate 10, allowing the clamping plate 10 to fit against the outer wall of the cable, achieving the effect of limiting the cable position. When the connecting column 2 1... When connecting to the first connecting post 3, the second connecting post 15 is inserted between the first connecting post 11 through the second contact plate 17, and is engaged with the second contact plate 12 through the third locking block 18 on the outer wall of the second contact plate 17 to prevent separation. The first contact plate 16 is inserted between the first connecting post 11 and the second connecting post 13 to further increase the contact area. Then, the bolt 19 is inserted into the first connecting post 11, the first contact plate 16 and the second contact plate 17. Finally, the bolt 19 is installed with the nut 20, thereby improving the connection strength of the busbar trunking.
