Flexible connection

definition: Flexible connection is made of multiple layers of copper foils superimposed and welded by polymer diffusion welding, with a smooth surface and no welding scars

. Function: With its good flexible conductive function, the flexible connection can eliminate the problem of poor conductivity of the battery pack caused by loose fasteners due to vibration during the operation of the car; at the same time, the insulating layer can slow down the oxidation corrosion of the internal copper foil and meet the insulation requirements between electrical components.

Classification: Copper flexible connection; Aluminum flexible connection;

Applicable scenarios: Power equipment, high-voltage electrical appliances, vacuum electrical appliances, mining explosion-proof switches, automobiles, locomotives

Features: Overall processing without welds; Highly protective housing; Spray-coated wear-resistant surface; Strong anti-interference ability; Metal waterproof joint; Measurement of harsh media; Easy installation and debugging; No leakage risks; Durable

Copper soft connection operating temperature: -40℃-300℃

Welding methods of copper foil soft connection:

1. Press welding soft connection: Press welding is to press the copper foil laminated parts together, use molecular diffusion welding, and press welding through high current heating; copper foil: 0.05mm-0.3mm thick

2. Brazing soft connection: Brazing is to press the copper foil laminated parts together, use silver-based brazing material, and weld with flat copper blocks; copper foil: 0.05mm-3mm thick
