[0002] Laminated busbar, also known as laminated busbar or composite copper busbar, is a multi-layer composite structure connection bar, which can be regarded as the highway of the distribution system. Compared with the traditional, bulky, time-consuming and troublesome wiring method, the use of laminated busbar can provide a modern, easy-to-design, fast-to-install and clearly structured distribution system. It is a high-power modular connection structure component with the characteristics of repeatable electrical performance, low impedance, anti-interference, good reliability, space saving, simple and quick assembly, etc.
[0003] During use, the existing laminated busbar uses an insulating plate to cover the upper and lower end surfaces, but no sealing structure is set at the edge position and the capacitor connection. As a result, when the laminated busbar is in use, water is easily introduced from the side or the capacitor connection, thereby affecting the safety of the laminated busbar. In addition, its conductive end plate is in an exposed state, and the external wire needs to be wrapped and tightened at the socket position of the conductive end plate at the connection, which is prone to leakage, affecting the overall sealing and waterproofing effect of the laminated busbar.
