Description

Technical Field

[0001] The utility model relates to the technical field of bus ducts, in particular to a spliced ​​bus duct. Background Art

[0002] With the emergence of modern engineering facilities and equipment, the electricity consumption of various industries has increased rapidly, especially with the emergence of numerous high-rise buildings and large factories and workshops. Traditional cables as transmission conductors can no longer meet the requirements in high-current transmission systems. The parallel use of multiple cables has brought many inconveniences to on-site installation and construction. Bus ducts have emerged as a new type of distribution conductor. They are a closed metal device composed of copper and aluminum busbars, which are used to distribute large power to various components of the distributed system. They have increasingly replaced wires and cables in indoor low-voltage power transmission trunk line projects.

[0003] Upon investigation, it was found that the Chinese utility model patent with publication number CN220066827U discloses a spliced ​​bus duct, comprising a first bus duct body and a second bus duct body, wherein the first bus duct body and the second bus duct body are fixedly connected with a pre-splicing mechanism and a lateral fixing mechanism.

[0004] In the above-mentioned bus duct, a lateral fixing mechanism is provided, and the movable plate buckle is pushed outward. When the second mounting plate is clamped into the recessed part of the locking rod, the movable plate buckle is pressed so that the distance between the first connecting plate and the second connecting plate has a certain adjustment range. When the first mounting plate and the second mounting plate are installed farther away, the tension of the elastic connecting arm is greater, thereby achieving the fixation of the first bus duct body and the second bus duct body. However, when the above-mentioned bus duct lateral fixing mechanism is just buckled, the elastic connecting arm is in a relaxed state and does not play a fixing role. Only when the movable plate buckle is pressed to adjust the distance between the first connecting plate and the second connecting plate, the elastic connecting arm gradually provides tension. This is also the process of separating the first bus duct and the second bus duct. In summary, the lateral fixing mechanism can only provide a certain reset tension at the beginning of the bus duct separation, and cannot play a role in fixing the spliced ​​bus duct.

[0005] Therefore, the utility model provides a spliced ​​bus duct to solve the above problems. Utility Model Content
