Product Overview

Sinyinda SYCBCHM01P6R1 is a 6-pin high-current plug male connector (current-sharing version) specifically designed for 120A-class pure power lithium battery transmission scenarios. This product adopts 6 identical 20A power terminals, supporting 6 parallel current-sharing channels to achieve 120A continuous current carrying capacity, and features industry-leading N+2 dual redundancy capability—even if any two pins fail simultaneously, the remaining 4 pins can still carry 80A regular load without derating or shutdown, providing dual safety fallback for mission-critical systems. It employs copper nickel-plated (50-80μ") high-wear-resistant contact technology, with a mating cycle life of ≥1000 times and stable contact resistance of ≤3mΩ; the PA66 insulating substrate balances mechanical strength and temperature resistance, with a rated voltage of DC 250V and an operating temperature range of -40℃ to +105℃. The enhanced snap-lock mechanism provides ≥60N holding force, and the asymmetric housing design physically prevents reverse insertion, with a recommended mating cycle life of 1000 times. It is particularly suited for applications with rigid requirements for "100A+ continuous current carrying capacity + ultimate availability," such as megawatt-level energy storage DC-side interconnection, heavy-duty truck battery-swap high-voltage fast charging, marine main propulsion power supplies, and data center UPS lithium battery cabinets, precisely pairing with the female socket SYCBCHM01P6R1F to form a complete 120A-class dual-redundancy power interconnection solution.

Core Advantages Exclusive to 120A Dual-Redundancy Power Terminals (6×20A Current-Sharing Version)

• 6×20A Homogeneous Terminals + N+2 Dual Redundancy Architecture:All 6 terminals are completely identical in size, material, plating, and crimping specifications, with an initial contact resistance dispersion of <5%, ensuring that the current distribution deviation among pins is <±3% under 120A load; when any two pins fail simultaneously due to contamination/damage/aging, the remaining 4 pins automatically share current to carry 80A regular load, and the system does not require derating or shutdown, improving availability to 99.999%, meeting the highest safety standards of "dual fault tolerance" for power systems as required by aviation-grade and classification society specifications.
• Copper-Nickel Plated (50-80μ") High-Wear-Resistant Contacts:Nickel plating thickness reaches 50-80μ" (1.27-2.03μm), hardness HV400-500, insertion wear <0.1μm/cycle, contact resistance change rate <10% after 1000 insertion cycles; the nickel layer offers excellent chemical stability, salt spray corrosion resistance >96h (5% NaCl), suitable for outdoor harsh environments of heavy-duty truck battery swap stations, marine salt spray conditions, and high-humidity energy storage container environments, at only 1/5 the cost of gold plating solutions.
• High-Strength PA66 Substrate for Load Bearing:Tensile strength ≥80MPa, flexural strength ≥120MPa, capable of withstanding high-speed docking impacts from heavy-duty truck battery swap robots (no cracking at 3m/s) and continuous marine vibration; CTI value ≥250V, meets UL94 V0 flame retardant rating, heat deflection temperature ≥240℃ (1.8MPa), short-term tolerance of 150℃ peak temperature without softening, ensuring no housing deformation under 120A transient surge.
• 14AWG Hydraulic Crimping Consistency Assurance:All 6 terminals adopt T2 copper forging construction, crimped with 14AWG cables using the SYC-H20 dedicated crimping tool, crimp area ≥2.5mm², pull-out force ≥150N/pin; mass production must use pneumatic crimping machines with closed-loop pressure sensor control, ensuring 6-pin crimping force dispersion <±5%, guaranteeing current sharing and dual-redundancy reliability from the process source.
• Enhanced Snap-Lock Mechanism:Addressing the increased insertion force of 120A high-current applications, the latch spring is widened and thickened with a tri-metal redundant design, locking retention force ≥60N (20% higher than 5Pin), release force ≤20N still supporting one-hand operation; even if a single spring breaks, ≥35N retention force is maintained, preventing accidental disconnection in high-vibration or elevated scenarios.
• -40℃~+105℃ wide-temperature current-sharing stability:PA66 substrate low-temperature toughness is modified and optimized, no cracking at -40℃ impact; at high temperature 105℃, the 6-pin contact resistance simultaneous rise rate <8%, avoiding current-sharing imbalance or premature redundancy depletion caused by temperature drift differences; sealing O-ring (optional) compression permanent deformation rate <20%, maintaining IP54 protection rating over long-term use.
