Key Points for Routine Maintenance of FFC/CCS Connectors
2025-06-18 11:13:07

In the operation of new energy equipment, standardized maintenance is crucial to ensuring the long-term stable performance of FFC/CCS connectors. Operators should establish a regular inspection schedule, focusing on checking the tightness of crimped terminal connections and inspecting for oxidation on contact surfaces. It is recommended to use a high-precision torque wrench to retighten connections to the standard value (typically 0.8–1.2 N·m). For cleaning, use specialized lint-free wipes along with electronics-grade cleaning agents, avoiding solvents like isopropyl alcohol that may corrode insulating materials.
In offshore wind power applications where connectors are exposed to salt spray, silicone grease coatings should be applied for protection and reapplied periodically. Additionally, monitor the aging of sealing rings to ensure the connector maintains a protection rating of IP54 or higher. During storage, maintain a stable environment with a temperature of 10–30°C and relative humidity of 30–60% to prevent warping or delamination of the FFC flexible circuit boards.
Special attention should be given to proper mating/unmating procedures: insertion/extraction force should be kept within 80% of the product’s rated value, and when the cumulative mating cycles reach 70% of the design limit, a preventive replacement program should be initiated.
