Why Is Stamped Pure Iron Bracket for Contactor Widely Used in DC Charging Pile Relays?

The new energy vehicle industry is experiencing rapid expansion. DC chargers, as high-power charging devices, have internal high-voltage relays as the core component for controlling the on-off state. The supporting components bear the magnetic circuit and the contact components, directly affecting the overall performance of the relay. The Stamped Pure Iron Bracket for Contactor, thanks to its excellent magnetic conductivity and stamping process advantages, has become the mainstream supporting component for high-voltage relays in chargers. The low magnetic resistance characteristic of pure iron material can optimize the magnetic field distribution and reduce energy loss during the large-power direct current switching process, making it suitable for fast-charging equipment's high-current working conditions. Outdoor chargers face complex temperature differences and dust environments, and the stability of the bracket material directly determines the long-term operational reliability of the relay.

The high-power DC charging scenarios impose strict standards on the durability of relay components. The equipment undergoes frequent high-frequency switching and continuous pressure, and the bracket needs to balance structural strength and environmental corrosion resistance. The EV Relay Bracket Pure Iron adopts an integrated stamping process, with an overall structure without any joint gaps, uniform mechanical strength, and the ability to withstand the electromagnetic impact force inside the relay, making it less prone to deformation or loosening. The raw materials undergo surface passivation anti-rust treatment, which can resist outdoor moisture and dust erosion, reducing rusting and failure over the long term, significantly reducing the frequency of later maintenance, and stabilizing the operating life of the entire charging equipment.

High-voltage safety is the first principle in the design of DC chargers. The magnetic circuit and isolation structure inside the relay rely on the bracket to achieve a regular layout, and the selection of components and forming process are directly related to the high-voltage protection effect. The Electrical Pure Iron Stamping for EV DC Contactor ensures dimensional accuracy by precise stamping molds, with controllable assembly clearance gaps, capable of precisely separating the high-voltage circuit from surrounding components, avoiding current leakage and short-circuit risks. The magnetic shielding effect of pure iron material is excellent, capable of weakening electromagnetic interference and preventing adjacent circuit signals from being disordered. Combined with the relay overload and power-off protection structure, it doubles the safety coefficient of the charger's charging operation and avoids dangerous situations such as overheating and arcs.

The stamping processing technology determines the forming accuracy and batch production consistency of the pure iron bracket. The internal space of the relay is compact, and the brackets are mostly in an irregular and ultra-thin structure, requiring high processing technology. The Iron Backet for EV DC Relay completes multiple processes such as cutting, bending, and drilling in one go using high-speed stamping equipment, with a unified mold standard ensuring minimal size deviation in the same batch of products, and it is suitable for automated assembly lines. The pure iron has moderate plasticity, making stamping easier to avoid cracking, and the wall thickness of the stamping parts is more uniform and lighter than those of cast parts, facilitating the miniaturization design of the relay and aligning with the current trend of lightweight and integrated charging equipment.

The technology of DC charging stations is continuously evolving, and high-voltage relays are constantly upgrading towards miniaturization, high power, and long lifespan. The comprehensive performance standards of internal supporting components are also being enhanced simultaneously. The HVDC Relay Skeleton Pure Iron integrates the characteristics of pure iron materials and precise stamping technology, while also considering multiple functions such as magnetic conductivity, structural support, and safety isolation. It perfectly meets the assembly requirements of various DC charging station high-voltage relays.
