Product Overview

The Sinyinda SYCBCHM01P5R1 is a 5-Pin high-current plug male connector (current-sharing version) specifically designed for 100A-class pure power lithium battery transmission scenarios. This product adopts 5 identical 20A power terminals, supports 5-way parallel current sharing to achieve 100A continuous current-carrying capacity, and features true N+1 redundancy—even if a single pin fails, the remaining 4 pins can still carry 80A of normal load without derating or shutdown. It employs copper nickel-plated (50-80μ") high-wear-resistant contact technology, with a mating cycle life of ≥1000 times 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℃ to +105℃. The enhanced snap-lock mechanism provides ≥50N 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 application scenarios with rigid requirements for "hundred-amp-level continuous current-carrying capacity + ultimate reliability," such as high-voltage energy storage cluster-level parallel connection, battery swap station high-power fast charging, heavy-duty AGV/forklift power ports, and marine lithium propulsion systems, precisely pairing with the female connector SYCBCHM01P5R1F to form a complete 100A-class redundant power interconnection solution.

Core Advantages Exclusive to 100A Redundant Power Terminals (5×20A Current-Sharing Version)

• 5×20A Homogeneous Terminals + N+1 Redundant Architecture:The 5 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 100A load; when a single pin fails due to contamination/damage/aging, the remaining 4 pins automatically share current to carry 80A of normal load, and the system does not require derating or shutdown, extending MTTR from emergency repair to planned maintenance windows, improving availability to 99.99%.
• Copper-Nickel Plated (50-80μ") High-Wear-Resistant Contacts:The nickel plating layer 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 battery swap station environments, high-humidity energy storage container conditions, and marine salt spray environments, at a cost of only 1/5 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 battery swap robots (no cracking at 2.5m/s) and vibration from heavy-duty AGVs; CTI value ≥250V, meets UL94 V0 flame retardant rating, heat deflection temperature ≥240°C (1.8MPa), short-term resistance to 150°C peak temperatures without softening, ensuring no housing deformation under 100A transient surge conditions.
• 14AWG Hydraulic Crimping Consistency Assurance:All 5 terminals feature forged T2 copper construction, crimped with the SYC-H20 dedicated crimping tool for 14AWG cable, with a crimp area ≥2.5mm² and pull-out force ≥150N per pin; for mass production, pneumatic crimping machines with closed-loop pressure sensor control are recommended to ensure a dispersion of <±5% across all 5 pins, guaranteeing current sharing and redundancy reliability from the process source.
• Enhanced Snap-Lock Mechanism:Addressing the increased insertion/withdrawal force of 100A high-current applications, the latch spring has been widened and thickened with a bimetallic redundant design, providing a locking retention force ≥50N (25% higher than 4-pin versions), while the release force ≤18N still supports one-hand operation; even if a single spring breaks, a retention force of ≥30N is maintained to prevent accidental disconnection in overhead or high-vibration scenarios.
• -40℃~+105℃ wide-temperature current-sharing stability:The PA66 base material has been modified for low-temperature toughness, with no cracking on impact at -40°C; at high temperatures up to 105°C, the simultaneous rise rate of contact resistance across the 5 pins is <8%, preventing current sharing imbalance or redundancy failure due to temperature drift differences; the optional sealing O-ring has a compression set rate of <20%, maintaining IP54 protection over long-term use.
