This process requires high-precision molds and advanced stamping equipment to ensure the dimensional accuracy and shape consistency of each component. Next, the Outer Cap and Contact are connected through laser welding technology. Laser welding provides a high-strength welding effect while avoiding thermal damage that may be caused by traditional welding methods. After welding, the component undergoes rigorous inspection, including dimensional inspection, conductivity testing, and mechanical strength testing. Only components that pass these strict inspections are used in the production of new energy vehicles. In addition, we have adopted advanced automated production lines, significantly improving production efficiency and the stability of product quality.
Application Fields
The Cap and Contact is mainly applied in the electrical systems of new energy vehicles. In these vehicles, the electrical system is responsible for providing power support to the vehicle's power system, control system, and auxiliary systems. As a key component of the electrical system, the End Cap and Contact ensures the safe operation of the circuit. It connects important components such as the high-voltage battery, motor controller, and on-board charger, providing reliable support for the vehicle's normal operation. Moreover, with the continuous development of new energy vehicle technology, the application scope of the Fuse Contact Knife Cap is also expanding.
