Abstract
Description
Technical Field
[0001] This utility model belongs to the field of busbar technology, specifically a busbar connection structure with a waterproof plug-in box. 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] Busbar trunking connections often employ butt-fitting installation due to structural design requirements. These connections are typically enclosed by covers or seals, resulting in narrow airflow space and slow air circulation. Heat accumulates at the connection points, hindering efficient heat exchange with the outside environment through air convection. The heat exchange rate is significantly lower than that of the main body of the busbar trunking, causing the temperature at these points to rise continuously and significantly reducing heat dissipation. Furthermore, the proximity of the air inlet to the connection point means that during rainy weather, external airflow may carry rainwater in through the inlet, and gaps or minor imperfections in the seals at the connection point can become channels for rainwater penetration. Therefore, this application proposes a busbar trunking connection structure with a waterproof plug-in box. Utility Model Content

Two busbar trunkings are installed on the wall. The heat dissipation mechanism includes a mounting frame installed between the two busbar trunkings. A motor is fixedly installed on the mounting frame, and a rotating rod is fixedly installed on the output end of the motor.
