Product Introduction
Stainless Steel Spring Contact Fingers
Stainless steel spring contact fingers are generally made by winding stainless steel wires through specific processes, presenting a spiral shape. They utilize the elastic properties of springs: when subjected to external forces, they can undergo elastic deformation to provide a certain contact pressure, thereby achieving reliable connection with other components. During the connection process, the spring contact fingers adapt to different contact surfaces and gaps through elastic deformation, ensuring good electrical and mechanical connections.
In terms of material selection, stainless steel materials with high strength, corrosion resistance, and high hardness are usually used, such as stainless steel grades like 304, 306, and 316. Then, high-precision wire winding equipment is employed to wind the stainless steel wires into spring contact fingers of specific shapes and sizes in accordance with design requirements. To further improve performance, surface treatments such as silver plating and gold plating are often carried out to reduce contact resistance and enhance oxidation resistance and corrosion resistance.
Stainless steel spring contact fingers have the following characteristics:
- Electromagnetic Interference Resistance: The stainless steel material itself has a certain electromagnetic shielding effect, which can reduce the impact of external electromagnetic interference on electrical connections and ensure the stability of signal transmission.
- Low Maintenance Cost: Due to their excellent performance and stability, they are less prone to failures under normal operating conditions, requiring no frequent maintenance or replacement.
Application Scope
- Electric Vehicles: Their core function is to ensure the stable transmission of high-voltage and high-current, and solve the problem of high-voltage connection reliability under vehicle vibration conditions.
- Industrial Automation: They can be used for PLC control systems and industrial sensor connections.
- Electromagnetic Shielding: They form a reliable electromagnetic sealing barrier, fill gaps in the shielding structure, block the leakage and intrusion of electromagnetic interference, and are suitable for scenarios requiring strict electromagnetic compatibility.
- Electronic Devices: They realize low-impedance signal/current connections. Their core role is to adapt to the connection of miniaturized and high-reliability electronic components, balancing the requirements of elastic contact and space occupation.
- Semiconductors: They are suitable for precision manufacturing and testing scenarios, meeting the strict requirements of semiconductor equipment for "high precision, low damage, and clean resistance", and are mainly used in manufacturing and testing links.
- Oil Pressure Sealing: They assist in enhancing the reliability and adaptability of the sealing structure. Through their own elasticity, they compensate for gap changes caused by seal wear, assembly deviations, or oil pressure fluctuations, and are mainly used in oil pressure systems with high requirements for sealing precision and durability.
