Flexible Laminated Soft Connector
Products Description
The Flexible Laminated Soft Connector is a highly flexible, high-current-carrying electrical connection component made from high-purity electrolytic copper foil using a special process. Its core consists of multiple (or single) layers of ultra-thin copper foil, bonded together at the ends using advanced processes such as molecular diffusion welding, polymer brazing, or integral pressure welding, forming a composite structure that is both flexible and rigid. Its design essence lies in utilizing the excellent ductility and flexibility of copper foil to construct an electrical path that can adapt to complex spatial layouts and withstand vibration and thermal cycling.
Manufacturing Advantages
Molecular Diffusion Welding/Polymer Brazing Core Technology
Copper Foil Bus Bar utilizes a molecular diffusion welding process under vacuum or protective atmosphere, the atoms at the copper foil contact surface diffuse into each other under high temperature and pressure, forming a metallurgical bond with properties consistent with the substrate. This results in near-zero joint resistance, high strength, and the absence of brittle solder phases. Polymer brazing achieves high-strength connections at relatively low temperatures, making it particularly suitable for connecting heat-sensitive components.
High-Precision Stamping and Forming
Precision progressive dies are used to cut and punch the Copper Foil Resistance Diffusion Soldering Flexible Connection, ensuring dimensional accuracy and edge quality. Automated alignment technology is employed for multi-layer lamination to ensure alignment of each layer and prevent uneven current distribution caused by misalignment.
Integrated Insulation and Protection Treatment
A variety of insulation solutions are available for Tinned Foil Connector for Electrical Battery, such as integral injection molding (PA6, PBT), silicone tubing, heat shrink tubing, or coating with high-performance insulating varnish. The system also features insulation layer withstand voltage testing and partial discharge detection capabilities.
Main Functions
| High-Efficiency Power Transmission | Copper Foil Connector serves as a low-impedance channel, efficiently collecting electrical energy from individual battery cells/modules to the main circuit. |
| Stress Buffering | Copper Foil Flexible Storage Energy Battery Busbar absorbs volume changes during battery charging and discharging, as well as vibrations and shocks during vehicle operation, protecting the cell terminals. |
| Auxiliary Thermal Management | High thermal conductivity copper helps to quickly dissipate heat from localized hotspots. |
| Electromagnetic Compatibility (EMC) Optimization | The tightly laminated structure of Copper Foil Bus Bar significantly reduces circuit inductance and suppresses EMI noise generated by switching transients. |
Frequently Asked Questions
How to choose between Copper Foil Connector and braided flexible connectors?
Laminated structures have lower resistance and higher current carrying capacity, making them suitable for main power connections above 100A; braided connectors offer better flexibility (multi-directional bending), making them suitable for low current applications or applications requiring frequent bending.
How do I determine if a multi-layer braided structure of Tinned Foil Connector for Electrical Battery is necessary?
If your application scenario involves extremely high instantaneous current demands (such as the acceleration current peak of electric vehicles), or requires distributing current from a main branch to multiple secondary branches, a multi-layer braided structure is recommended. It provides lower contact resistance and higher reliability.
Will the connection loosen due to thermal expansion and contraction after prolonged use?
Our Copper Foil Flexible Storage Energy Battery Busbar connection employs a thermal expansion coefficient matching design and are secured using a professional welding process. Even in extreme environments ranging from -45°C to +150°C, it maintains structural robustness and electrical performance stability.
