Sheet Metal Relay Yoke
Products Description
In electric vehicles and high-voltage distribution architectures, the electromagnetic conversion efficiency and current-carrying capability of relays are fundamental to system integrity. The Sheet Metal Relay Yoke, serving as the primary flux-guiding structure within the electromagnetic loop, determines contact force stability and arc erosion resistance through its physical property consistency.
Product Features and Functions
Magnetic Conducting Function
The Relay Steel Yoke acts as a magnetic conducting channel in the electromagnetic circuit, concentrating the magnetic field generated by the coil, improving the relay's electromagnetic conversion efficiency, and reducing coil operating current and heat generation.
01
Structural Load-Bearing Function
The Pure Iron Relay Yoke Plate adopts an integrated bent-formed bracket structure, simultaneously supporting the electromagnetic coil and moving/stationary contact components, replacing separate brackets and reducing the number of parts in the overall assembly.
02
Installation and Positioning Function
Standardized pre-drilled mounting holes ensure compatibility with the Yoke Mount Kit for Relay, precisely controlling the air gap in the magnetic circuit and ensuring stable relay engagement and disengagement.
03
Deformation Resistance and Buffering Function
The Relay Yoke Stamping uses a bent, reinforced, integrated stamping process to maintain a constant magnetic circuit gap under vehicle-mounted vibration conditions, preventing contact malfunctions and relay misoperation.
04
Corrosion Protection Function
The base material undergoes passivation treatment after stamping, isolating it from air and corrosive media. The Relay Iron Yoke Bracket is suitable for harsh, enclosed environments such as engine compartments and energy storage cabinets in new energy vehicles.
05
Material Advantages
Magnetic Performance Batch Stability
Each batch undergoes rapid magnetic performance testing to ensure that the fluctuation range of coercivity and maximum permeability is narrowed to within ±5% of the standard value. This indicator directly affects the consistency of relay operation after mass production and vehicle assembly.
01
Low Coercivity Advantage
Low coercivity ensures rapid reset of the Power Relay Yoke after relay release, reducing the risk of contact adhesion, especially significantly improving contact electrical life under frequent on/off conditions of pre-charged relays.
02
Controllable Work Hardening
The material of Magnetic Yoke Metal Stamping for EV Relay exhibits a gradual work hardening trend during stamping and bending, preventing abnormal die wear or cross-sectional cracking caused by a sudden increase in edge hardness due to continuous stamping.
03
Welding/Bragging Compatibility
The material has an extremely thin oxide layer, making it highly compatible with resistance spot welding, laser welding, or induction brazing processes. This facilitates a reliable connection between the Precision Relay Yoke Stamping Part and other magnetically conductive components during customer assembly.
04
Product Application Advantages
Optimized Overall Relay Size/Weight
The Relay Coil Yoke structure integrates mounting clips, positioning posts, and other features, reducing additional fasteners and helping customers achieve lightweight relays.
Reduced Assembly Costs
High-precision positioning of the Precision Relay Yoke Metal Stamping Parts eliminates the need for manual adjustments during relay assembly, adapting to fully automated assembly islands and reducing process cycles and manual intervention.
Enhanced After-Sales Reliability
The Electromagnetic Relay Yoke Frame offers excellent consistency, fatigue resistance, and corrosion resistance, extending the relay's functional integrity throughout its automotive lifespan.
