Flat Electrical Contact
Products Description
Flat electrical contacts are precision functional components developed to meet the "surface contact conductivity requirement." Through the surface composite molding of dissimilar metals, they achieve three-dimensional optimization of "contact uniformity, space compactness, and performance stability." As a core conductive component of highly integrated electrical equipment, its core value lies in solving the industry pain points of traditional point/line contact components, such as "large contact resistance fluctuations, high space occupancy, and easy failure at high frequencies." They are widely used in key components such as power modules, sensors, connectors, and relays in fields such as new energy vehicles, industrial precision control, medical equipment, and high-end consumer electronics, serving as a "conductive connection bridge" supporting the miniaturization and high-density integration of equipment.
Key Features: Structural and Performance Characteristics Adapted to Highly Integrated Scenarios
Surface Contact Structure Design
The contact area is a regular plane, increasing the contact area by more than 40% compared to traditional Stationary Electrical Contact, resulting in more uniform current distribution and avoiding localized heat concentration.
Ultra-thin and Compact Form Factor
The overall thickness is controlled within the range of 0.1mm-3mm, adapting to confined installation spaces and supporting lightweight and high-density assembly layouts;
Multi-dimensional Environmental Tolerance
Resistant to high and low temperatures (-55℃~150℃), resistant to damp heat and salt spray, and resistant to arc erosion, suitable for various environments such as automotive, industrial outdoor, and medical cleanrooms;
Multi-functional Installation Compatibility
Supports multiple installation methods such as welding (laser welding, brazing), bonding, and snap-fit fixing, requiring no special assembly equipment and adapting to different production processes.
Manufacturing Process: An Industrial Benchmark for Flexible Manufacturing
Material Composite
Copper strip and polymer substrate are plasma-enhanced composited in an inert gas atmosphere, resulting in a pore-free interface.
01
Microforming
A servo press performs 0.01mm precision stamping, ensuring a thickness tolerance of ±0.005mm.
02
Surface Treatment
An environmentally friendly nano-coating (0.1μm thick) is electrochemically deposited to enhance corrosion resistance.
03
Smart Packaging
Each Stationary Silver Contact is independently protected against static electricity and comes with a QR code traceability system, supporting full lifecycle management.
