Description

Technical Field

[0001] This utility model relates to the field of busbar technology, specifically to a busbar that can be connected side by side. Background Technology

[0002] Busbar trunking uses copper or aluminum as conductors, is supported by non-alkaline insulation materials, and is encapsulated in a metal trough to form a high-efficiency power transmission system. Its original design purpose was to solve the limitations of traditional cables in high-current transmission scenarios. It is especially suitable for high-capacity power distribution needs in modern high-rise buildings, industrial plants, etc. In factories with high-power equipment, using busbar trunking for power transmission is the preferred choice. In factories with many equipment, multiple busbar trunkings are usually used for power transmission. However, existing busbar trunking is installed individually. When multiple busbar trunkings are installed at the same time, they cannot be connected side by side. The installation is time-consuming and labor-intensive, wastes fasteners, and also affects the aesthetics of the line.

[0003] Chinese Utility Model Patent Publication No. CN213959677U discloses a parallel-connectable aluminum alloy busbar trunking. During installation, the first busbar trunking shell is fixed to the outside using bolts through bolt holes. The second busbar trunking shell is installed by mounting a retaining plate on the ribs of the first busbar trunking shell, and then securing it with bolts to one end of the ribs. The third busbar trunking is installed in the same manner. This installation method achieves parallel connection of busbar trunking, is simple and convenient, uses few fasteners, and is aesthetically pleasing. However, the bolt connection between adjacent busbar trunking shells is relatively slow, and the lack of a heat dissipation structure means the copper busbars inside the busbar trunking operate at high temperatures for extended periods, making them prone to damage and affecting overall usability. Therefore, its practicality is poor and it is not suitable for widespread use. Summary of the Invention

This also facilitates maintenance and replacement after prolonged use. Then, the operator inserts connecting block 10 into connecting slot 17, enabling quick positioning between the first busbar 1, second busbar 2, and third busbar 3. After quick positioning of the first busbar 1, second busbar 2, and third busbar 3, the operator inserts connecting plate 21 into slot 18, and simultaneously inserts guide block 22 into the guide slot. Inside the slot 19, the connecting plate 21 can be quickly positioned. After the connecting plate 21 is quickly positioned, the operator extends the limiting rod 24 through the limiting slot 23 into the limiting slot 20, which can quickly limit the connection of the connecting plate 21, thereby achieving a quick connection between the first busbar slot 1, the second busbar slot 2, and the third busbar slot 3. The installation efficiency is high, and it is easy to maintain after long-term use. During use, the design of multiple fixing blocks 1 6 and fixing blocks 2 13 improves the firmness and stability of the connection between the first busbar slot 1, the second busbar slot 2, and the third busbar slot 3, making it highly practical. The design of the ventilation hole 25 facilitates air circulation inside the first busbar slot 1, which facilitates heat dissipation of the copper busbar inside the first busbar slot 1 and prevents the copper busbar inside the first busbar slot 1 from working in a high-temperature environment for a long time, which could lead to damage and affect the normal use of the whole. It is also highly practical.
