Product Overview

The Sinyinda SYCBCHM01P2R1 is a 2Pin high-current plug male connector (copper-nickel plated version) specifically designed for 20A-class lithium battery power transmission scenarios. This product adopts a copper-nickel plated (50-80μ") high-wear-resistant contact process, with a mating cycle life of ≥1000 times and stable contact resistance ≤3mΩ, perfectly balancing conductivity, wear resistance, and cost; the PA66 insulating substrate combines mechanical strength and temperature resistance, with a rated current of 20A, rated voltage of DC 250V, and operating temperature range of -40℃~+105℃. The integrated snap-lock mechanism provides ≥30N retention force, supports one-hand quick mating and unmating, with a recommended mating cycle life of 1000 times. It is particularly suitable for scenarios with rigid requirements for "20A continuous current-carrying + wear resistance + cost sensitivity," such as lithium battery PACK output interfaces, power tool battery packs, two-wheeled electric vehicle charging ports, AGV automatic charging contacts, and portable energy storage power supplies, precisely pairing with the female connector SYCBCHM01P2R1F to form a complete 20A-class lithium battery power interconnection solution.

Core Advantages Exclusive to Lithium Battery Power Terminals (Copper-Nickel Plated Version)

• 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, far exceeding gold plating (HV130) and tin plating (HV15); the wear amount per mating cycle is <0.1μm, and the contact resistance change rate after 1000 mating cycles is <10%; the nickel layer exhibits excellent chemical stability, with salt spray corrosion resistance >96h (5% NaCl), suitable for humid and dusty environments such as outdoor power tools and two-wheeled vehicles, at a cost of only 1/5 of gold-plated solutions.
• PA66 Substrate Mechanical Strength Assurance:Tensile strength ≥80MPa, flexural strength ≥120MPa, 30% higher than PA6, capable of withstanding drop impacts from power tools (no cracking after 1.5m free fall); CTI value ≥250V, meeting UL94 V0 flame retardant rating, heat deflection temperature ≥240℃ (1.8MPa), and short-term resistance to 150℃ peak temperature without softening.
• 20A Terminal Hydraulic Crimping Process:The main circuit terminal adopts a T2 purple copper forged structure, crimped with a 14AWG dedicated crimping tool (model SYC-H20), with a crimping area ≥2.5mm², pull-off force ≥150N, contact resistance ≤3mΩ, and terminal temperature rise <30K at 20A full load, avoiding the risk of loose connections and overheating caused by traditional manual crimping pliers.
• Integrated snap-lock mechanism:Press-type elastic snap design, with locking retention force ≥30N and unlocking force ≤10N, supporting one-hand blind mating operation while wearing gloves; the snap features a built-in metal spring leaf to enhance fatigue life, maintaining reliable locking after 5,000 presses, offering superior assembly efficiency compared to traditional screw-fixing solutions, especially suitable for frequent battery replacement scenarios in power tools.
• Reverse polarity protection design:The housing adopts an asymmetric trapezoidal profile with guide rib grooves, providing physical keying to prevent reverse insertion of positive and negative terminals, avoiding the risk of battery short-circuit burnout; the guide rib groove depth is 2mm, ensuring complete contact alignment before mating, preventing arc damage during live plugging and unplugging.
• Wide temperature range -40℃~+105℃:The low-temperature toughness of the PA66 base material is modified and optimized, with no cracking on impact at -40℃; at high temperature 105℃, the dimensional change rate is <0.3%, meeting the temperature differential requirements of outdoor energy storage and northern winter power tools; the sealing O-ring (optional) has a compression set rate of <20%, maintaining IP54 protection rating during long-term use.
