Description

Technical Field

[0001] The utility model relates to the technical field of power distribution cabinet assembly, and specifically relates to a modular power distribution cabinet copper bar fixing device. Background Art

[0002] The copper busbar in the distribution cabinet is mainly used for the transmission and conduction of current. The existence of the copper busbar also plays a certain role in safety protection. It can protect the safety of the distribution cabinet in overload and other situations through its own current carrying capacity, and avoid dangerous situations such as fire or electric shock. The installation and fixation of the copper busbar in the distribution cabinet needs to be carried out in accordance with certain specifications and requirements to ensure its stability and reliability.

[0003] If the copper busbar is not firmly fixed during installation, it will bring many disadvantages and shortcomings. Insecure fixation will cause the copper busbar to vibrate or move during current transmission, affecting the stable conduction of current, thereby affecting the stability and reliability of the entire power distribution system. If the copper busbar becomes loose, falls off or short-circuits during operation, it is also easy to cause safety accidents such as fire or electric shock. In addition, if the fixation is not secure, more time and effort will be spent on maintenance and repair, increasing maintenance costs and time. Therefore, we propose a modular distribution cabinet copper busbar fixing device to ensure the normal operation and safety of the copper busbar in the distribution cabinet. Utility Model Content

[0004] The utility model aims to provide a modular distribution cabinet copper bar fixing device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a modular distribution cabinet copper busbar fixing device, comprising a modular distribution cabinet, wherein the lower surface of the inner wall of the modular distribution cabinet is symmetrically fixedly connected with a support rod, the other end of the support rod is fixedly connected with a top block, the inner cavity of the top block is provided with a groove, and the groove of the top block is provided with a rotating structure, the lower surface of the rotating structure is fixedly connected with a screw rod, the outer wall of the screw rod is threadedly connected with a sleeve block, the center of the sleeve block is gap-matched with the outer wall of the support rod, the other end of the screw rod is threadedly connected with a screw block, the upper surface of the screw block is fitted with the lower surface of the sleeve block, the lower surface of the top block is fixedly connected with a round rod, the outer wall of the round rod is sleeved with a copper busbar, and the lower surface of the copper busbar is fitted with the upper surface of the sleeve block.

[0006] Preferably, the rotating structure includes a groove block, a side wall of the groove block is provided with a ball, the other side of the ball is fitted with the inner cavity groove of the top block, the upper surface of the groove block is fixedly connected to a turning handle, and the other end of the groove block is fixedly connected to the upper surface of the screw.

[0007] Compared with the prior art, the beneficial effects of the utility model are as follows: when the copper busbar is installed inside the modular power distribution cabinet, the fixing structure is improved, the fixing method is changed to a symmetrical clamping method, and the fixing is performed by a bolt with a rotating structure. Compared with the traditional fixing method, such as fixing only by point-to-point rivets or welding, this fixing method greatly simplifies the installation process. The symmetrical clamping design allows the installer to fix the copper busbar more quickly and accurately. At the same time, a screw block is set at the other end of the bolt. After the copper busbar is symmetrically clamped on both sides, the bottom screw block is tightened. Threaded fixation keeps the copper busbar stable, ensuring its stability and reliability. This double threaded fixation method can significantly improve the stability of the copper busbar. When subjected to external forces such as electric force, the copper busbar can better resist deformation and movement. The upper and lower symmetrical clamping design can create a larger space margin between the copper busbar and the cabinet structure, which is beneficial to the heat dissipation and ventilation of the cabinet. It also provides more space for the installation of other equipment or lines. By improving the fixing structure, the stability and reliability of the copper busbar are improved, reducing the risk of accidents caused by equipment failure and improving the safety of equipment use.
