Description
Technical Field
[0001] This utility model belongs to the field of busbar technology, specifically a modular, expandable, and splicable busbar connection structure. Background Technology
[0002] The busbar trunking connection structure is a core component that ensures the safe and stable operation of the busbar trunking system. Through a fastening structure, the segmented busbar trunking is firmly spliced together to form an overall rigid frame, resisting external forces such as vibration and impact during installation and operation. At the same time, it ensures the expansion and contraction adaptability of the busbar trunking under temperature changes, maintains structural integrity, and the connection structure achieves reliable docking of conductors in adjacent busbar trunkings through conductive components, reducing contact resistance, reducing power loss and heat generation in power transmission, and ensuring stable passage of large currents.
[0003] When connecting busbar trunking, adjacent units need to be connected via flanges or connecting frames. Fixing these components requires installing dozens of screws around the perimeter. During installation, it is necessary to ensure that each screw is evenly stressed to prevent poor contact, and each screw must be tightened and checked individually, which consumes a lot of time and manpower. If the screw positioning is off during installation, repeated disassembly and adjustment are required, further increasing the complexity of the operation. This screw-dependent connection method also makes length adjustment difficult. When it is necessary to shorten or lengthen the busbar trunking, all fixing screws must be removed one by one, the connecting components must be separated, the corresponding length unit must be replaced, and then all screws must be reinstalled and tightened. The whole process is cumbersome, and frequent screw removal can easily cause thread wear, affecting the stability of subsequent connections. At the same time, power supply must be interrupted during adjustment, making it difficult to achieve quick and flexible length adaptation. Ultimately, this makes installation and adjustment face significant operational obstacles. To address this, this application proposes a modular, scalable, and splicable busbar trunking connection structure. Utility Model Content
