There are dovetail grooves and dovetail protrusions symmetrically designed on the side, the dovetail grooves and dovetail protrusions of adjacent plastic parts cooperate with each other, anti-loosening steel nuts are designed on the plastic parts, and clamping square holes are designed between the plastic parts and the current-carrying copper parts , the two ends of the series-parallel compression seat are designed with an upper compression plate, the side of the upper compression plate is designed with a lower compression plate, the lower compression plate and the upper compression plate are integrated, the lower compression plate and the upper compression plate Both are provided with fixing holes, the internal thread of the anti-loosening steel nut is connected with a bolt assembly, and the lower pressing plate and the lower surface of the upper pressing plate are fixedly connected with a clamping square column.
Description
technical field [0001] The invention relates to a connector assembly, in particular to a series-parallel connector assembly of a soft pack lithium battery. Background technique [0002] Lithium batteries have the advantages of small size, light weight, high energy density, safety and environmental protection, making lithium batteries undoubtedly become the development direction of power batteries. The characteristics of high energy density and convenient combination of soft-pack lithium batteries make soft-pack lithium batteries have a very broad market, but the series and parallel connection of pole pieces of soft-pack lithium batteries is still a bottleneck restricting its development. At present, tin welding, ultrasonic welding and other methods are mostly used for the series-parallel connection of soft-pack lithium battery pole pieces. The number of parallel connections is limited. Therefore, for the long-term development of soft-pack lithium batteries, the series-para...
