Shield Cap For HEV DC Relay
Products Description
Our Shield Cap for HEV DC Relay is a core shielding component specifically designed for new energy high-voltage DC contactors. Also known as the Shielding Cover for New Energy High Voltage DC Contactor and Shielding Cover for EV DC Contactor, it effectively suppresses electromagnetic interference, ensuring stable operation of the high-voltage DC system.
Our Shielding Cover for EV DC Contactors widely serves high-voltage DC relay manufacturers, customers in the new energy vehicle industry chain, and precision stamping/metal processing suppliers, and are indispensable key components in new energy vehicle high-voltage systems.
Key Selling Points
Material Properties
The Shielding Cover for New Energy High Voltage DC Contactor is made of high-purity electrical pure iron, possessing excellent magnetic permeability and magnetic shielding performance, effectively attenuating high-frequency electromagnetic radiation. The surface is nickel-plated/zinc-plated, withstanding salt spray corrosion for ≥480 hours, making it suitable for the harsh working environment of new energy vehicles.
Manufacturing Process
The Pure Iron Shell for DC Relay employs precision stamping and deep drawing processes, with dimensional tolerances controlled within ±0.05mm. Combined with CNC turning and laser welding processes, it ensures the airtightness and structural strength of the shell, meeting IP67 protection requirements.
Technical Features
The Shielding Cover for EV DC Contactor features a one-piece stamped structure with no seams, providing shielding effectiveness ≥80dB (10kHz-1GHz). The smooth, burr-free inner wall prevents wear on the relay's internal coil and contacts. It is compatible with the mounting interfaces of mainstream brand high-voltage DC relays, allowing for rapid integration without additional mold opening.
