Micro Spring Contact Fingers

Key Features of Micro Spring Contact Fingers

• Excellent Electrical Performance: They have low resistance, ensuring efficient current transmission; meanwhile, they provide a stable channel for high-frequency signals, guaranteeing the integrity and accuracy of the signals.
• Reliable Mechanical Performance: They exhibit good elasticity, enabling stable pressure contact in small spaces; they also have strong fatigue resistance—after special process treatment, they can withstand frequent telescopic deformations and extend their service life.
• Strong Environmental Adaptability: They have a wide operating temperature range and can work reliably for a long time in environments with a relatively broad temperature span.
• High Dimensional Precision: With small sizes, they can meet the connection needs of miniature electronic devices; they also feature high precision, as their dimensional tolerances can be controlled within an extremely small range, allowing for high-precision matching with other micro-components.

Application Fields of Micro Spring Contact Fingers

• Electric Vehicles: Their core function is to ensure stable transmission of high-voltage and high-current, and solve the problem of high-voltage connection reliability under vehicle vibration conditions.
• Electronic Devices: They realize low-impedance signal/current connection. 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.
• Medical Equipment: They are used for micro-circuit connection in large-scale medical testing equipment such as X-ray machines and B-ultrasound machines, ensuring that the equipment can accurately collect and transmit testing data during long-term use.
• Communication Terminal Equipment: They are applied in internal circuit connection of devices such as routers and switches to ensure the stability and reliability of the equipment during data transmission.
• Industrial Automation: They can be used for PLC control systems and industrial sensor connections.
• Aerospace: They are suitable for avionics equipment, aerospace vehicles, and other related products.
• Semiconductor Equipment: They adapt to 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.
• Unmanned Aerial Vehicles (UAVs): They can achieve stable electrical connection between internal electronic devices of UAVs; they also play an electromagnetic shielding role, effectively isolating the impact of external electromagnetic interference on internal electronic components.
• Robotics: They are mainly used for connections between internal circuit boards of robots, and between electronic components and circuit boards, as well as in joint drive, grasping operations, and sensor feedback.
• Rail Transit: They are used in train control systems, on-board power supply systems, etc.
• Energy Storage and Energy Supplement Equipment: In energy storage and energy supplement equipment, especially in high-power charging scenarios, a large amount of heat is generated. Micro spring contact fingers can be combined with a temperature sensing system, and adaptively adjust the contact state through their elastic characteristics to help dissipate heat, effectively solving the problem of local overheating and improving the thermal management performance of the equipment.
