Product Overview

The Sinyinda SYCBCHF01P6DIP is a 6Pin high-current female connector (solder type) designed for 120A-class pure power lithium battery transmission scenarios. This product adopts 6 identical 20A power terminals, supporting 6 parallel current-sharing paths to achieve 120A continuous current capacity, and features true N+4 ultimate redundancy capability—even if a single pin fails, the remaining 5 pins can still carry 100A normal load; with two pins failed, it maintains 80A emergency operation; with three pins failed, it still supports 60A safe return/shutdown; with four pins failed, it still provides 40A minimum guarantee. It adopts copper nickel-plated (50-80μ") high-wear-resistant contact technology, with a mating life of ≥1000 cycles and stable contact resistance ≤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℃~+105℃. The six-hole positioning design ensures installation accuracy of ±0.1mm, the asymmetric housing provides physical reverse-connection prevention, and the recommended mating life is 1000 cycles. The U-slot structure supports direct press-in soldering of AWG 10-18 gauge wires without pre-tinning, greatly improving assembly efficiency. It is particularly suited for application scenarios with rigid requirements for "120A-class power + flexible wiring + manual/semi-automatic assembly + ultimate redundancy," such as TWS earbud charging case super-fast-charging ports, smartwatch magnetic charging bases, micro drone battery interfaces, and medical portable device power modules. It pairs precisely with the male connector SYCBCHM01P6R1 to form a complete 120A-class solder-type lithium battery interconnection solution.

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

• 6×20A Homogeneous Terminals + N+4 Ultimate Redundancy Architecture:6 terminals with identical dimensions, material, plating, and pad specifications, initial contact resistance dispersion <5%, ensuring current distribution deviation among pins under 120A load is <±3%; when a single pin fails, the remaining 5 pins automatically share current to carry 100A normal load; with two pins failed, maintain 80A emergency operation; with three pins failed, still support 60A safe return/shutdown; with four pins failed, still provide 40A minimum guarantee, system availability improved to 99.999%, MTTR extended from emergency repair to planned maintenance window.
• Copper-Nickel Plated (50-80μ") High-Wear-Resistant Contacts:The nickel plating thickness reaches 50-80μ" (1.27-2.03μm), with a hardness of HV400-500, mating wear of <0.1μm per cycle, and a contact resistance change rate of <10% after 1000 mating cycles; the nickel layer exhibits excellent chemical stability, with salt spray corrosion resistance of >96h (5% NaCl), making it suitable for outdoor smart wearables, sweat environments in sports earphones, and high-altitude low-temperature conditions for drones, at a cost of only 1/5 of gold-plating solutions.
• High-Strength PA66 Substrate for Load Bearing:Tensile strength ≥80MPa, flexural strength ≥120MPa, withstands frequent open/close impacts of TWS earbud cases (5000 cycles without cracking) and micro drone drop vibration; CTI value ≥250V, meets UL94 V0 flame rating, heat deflection temperature ≥240°C (1.8MPa), short-term tolerance of 150°C peak temperature without softening, ensuring housing does not deform under 120A transient surge.
• U-Slot Wire Crimping Structure + No Pre-Tinning Required:The U-slot (width 2.5mm, depth 1.8mm) is designed at the bottom of the terminal, supporting direct press-in of AWG 10-18 gauge wires followed by soldering, without the need for pre-tinning or crimping terminals, greatly simplifying the assembly process; solder joint fullness is improved by 30%, and the cold solder joint rate is reduced to <0.1%.
• Asymmetric housing + guide groove dual keying:Housing adopts trapezoidal profile + asymmetric guide rib/groove design, 6Pin positions uniquely matched, completely eliminating reverse insertion risk; guide groove depth 2.5mm, ensuring all contacts are fully aligned before mating, avoiding arc damage from hot plugging, supporting blind mating operation.
• -40℃~+105℃ wide-temperature current-sharing stability:PA66 base material low-temperature toughness optimized through modification, no cracking at -40°C impact; at high temperature 105°C, 6-pin contact resistance synchronous rise rate <8%, avoiding current imbalance or redundancy failure caused by temperature drift differences; sealing O-ring (optional) compression set rate <20%, maintaining IP54 protection rating during long-term use.
