Not only is the installation time-consuming, but the processing cost is also high. We have developed the extruded copper busbar for the connection between the power battery modules of new energy vehicles. The extruded copper busbar uses T2 copper raw materials, which has low resistivity, high conductivity, low temperature rise, and heat dissipation. Compared with traditional cable products, it has faster processing speed, higher efficiency, and lighter weight. The special structural design means that it can be twisted, bent, and folded to a large extent.

When the copper busbar fixing structure is loose, poor contact at the copper busbar connection may occur, thereby causing a short circuit. In addition, the necessary buffer structure is lacking. Once subjected to a large impact, the impact force may cause damage to the copper busbar, thereby affecting the conductivity and connection problems. Utility Model Content
