Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to an anti - falling - off structure for bus duct joints. Background Technique

[0002] A bus duct is a closed metal device composed of copper or aluminum bus bars, used to distribute relatively large power to each component of a decentralized system. It is mainly formed by a conductor system, which consists of bus bars spaced and supported by insulating materials in pipes, troughs or similar enclosures. Due to its outstanding advantages such as strong current - carrying capacity, simple and convenient installation, high safety, and long service life, it is an important part of the low - voltage distribution trunk system in the low - voltage distribution design of building electricity, and is widely used in power supply and distribution places such as factories, commercial centers, high - rise buildings, data centers, and lighting systems. At the joints of bus ducts, connections are often made through bus duct joints. Existing bus duct joints mostly use locking - torque bolts to ensure the friction between the insulating phase - separating blocks and the conductors, without corresponding anti - falling - off structures, which is relatively dangerous to use. Therefore, an anti - falling - off structure for bus duct joints is designed to solve the above problems. Content of the Utility Model

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution: an anti-dropping structure for a busbar joint, including: two busbar main bodies 1, cover plates 2 are arranged at the upper and lower ends of the busbar main body 1, the cover plates 2 are connected to the busbar main bodies 1 on the left and right sides by screws, pressing plates 3 are connected to the front and rear ends inside the busbar main body 1, the front pressing plate 3 is in close contact with the ground wire inside the busbar main body 1, one end of the pressing plate 3 is provided with a slope inclined outward, the upper end of the busbar main body 1 is provided with insulating phase separation blocks 4 with hollow interiors in an array, a conductive plate 5 with a hollow interior is arranged between the insulating phase separation blocks 4, outer baffles 6 with hollow interiors are arranged on the outer sides of the insulating phase separation blocks 4 at the front and rear ends, an inward inclined slope is provided at the inner side of one end of the outer baffle 6, a washer 7 is arranged at the opening of the middle hole of the insulating phase separation block 4, an insulating partition tube 8 is arranged at the rear end of the rear outer baffle 6, the insulating partition tube 8 is inserted into the holes inside the insulating phase separation block 4, the conductive plate 5, the outer baffle 6, a torque bolt 9 is arranged at the front end of the insulating partition tube 8, a pressing block 10 is arranged at the front end of the torque bolt 9, and the pressing block 10 is threadedly connected to the torque bolt 9.

[0024] During use, the insulating partition tube 8 is inserted into the interiors of the insulating phase separation block 4, the conductive plate 5, and the outer baffle 6, then the torque bolt 9 is inserted into the interior of the insulating partition tube 8, and the other end is fixed by the pressing block 10. The lower ends of the two busbar main bodies 1 are connected to the upper cover plate 2 by screws. The insulating phase separation block 4, the conductive plate 5, and the outer baffle 6 are pressed downward from the upper end. The conductors of one busbar main body 1 are clamped between adjacent two insulating phase separation blocks 4. The pressing plate 3 is clamped between the insulating phase separation block 4 and the outer baffle 6. Then it is pushed downward until the lower end of the outer baffle 6 contacts the lower cover plate 2. Then the torque bolt 9 is tightened. After the nut at one end of the torque bolt 9 is broken off, the installation is completed. Finally, the upper cover plate 2 is locked by screws to complete the installation. When loosening occurs and the busbar main body 1 slides outward, the slopes of the outer baffle 6 and the pressing plate 3 will contact each other and squeeze inward at the same time, making the insulating phase separation block 4 clamp tighter to prevent dropping.

[0025] Such as Figures 1-2As shown, an embodiment of the utility model provides an implementation method, based on the above implementation method, the inner sides of the three middle insulating phase-isolating blocks 4 and the insulating phase-isolating blocks 4 at the front and rear ends are all provided with conductive plate slots, the conductive plate 5 is inserted and connected with the conductive plate slots, and the thickness of the conductive plate 5 is thicker than the thickness of the conductive plate slots.

[0026] From the analysis of the above structure, it can be known that the conductive plate 5 is inserted into the conductive plate slot inside the insulating phase isolation block 4, which can prevent the conductive plate 5 from shaking and rotating at an angle, and facilitates installation.

[0027] like Figures 1-2 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the total thickness of the two washers 7 is the same as the thickness of the wire inside the bus duct body 1.

[0028] Analysis of the above structure shows that the total thickness of the gasket 7 is the same as the thickness of the wire inside the bus duct body 1. When locking, it can act as a limit to prevent the insulating phase-isolating block 4 from being crushed.

[0029] like Figures 1-2 As shown, the embodiment of the utility model provides an implementation method. Based on the above implementation method, the outer diameter of the gasket 7 is larger than the diameter of the inner hole of the conductive plate 5.

[0030] From the analysis of the above structure, it can be known that the outer diameter of the gasket 7 is larger than the diameter of the inner hole of the conductive plate 5 , and the outer side of the gasket 7 can press the conductive plate 5 to prevent the conductive plate 5 from shifting in position.

[0031] like Figures 1-4 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, the height of the extrusion plate 3 and the outer baffle 6 is the same as the height of the bus duct body 1.

[0032] From the analysis of the above structure, it can be known that after installation, the upper and lower ends of the extrusion plate 3 and the outer baffle plate 6 will support the cover plate 2 to play a role in horizontal positioning.

[0033] like Figures 1-3 As shown, an embodiment of the utility model provides an implementation method. Based on the above implementation method, the left and right ends of the outer side of the outer baffle plate 6 are connected with force component plate grooves 21, and a force component plate 22 which is generally arc-shaped and hollow inside is inserted and connected between the left and right force component plate grooves 21. The force component plate 22 is sleeved on the outside of the torque bolt 9.

[0034] From the analysis of the above structure, it can be known that when the torque bolt 9 is tightened, the torque bolt 9 will press against the force distribution plate 22, and the force will be applied more evenly through the force distribution plate 22 to prevent the force from gathering in one place.

[0035] like Figures 1-3As shown, an embodiment of the present utility model provides an implementation manner. Based on the above implementation manner, arc chamfers are provided at both the front and rear ends of the lower end of the insulating phase separation block 4.

[0036] Analyzing the above structure, it can be seen that the arc chamfers provided at both the front and rear ends of the lower end of the insulating phase separation block 4 can play a guiding role when the insulating phase separation block 4 is inserted downward, facilitating the insertion of the insulating phase separation block 4.
