IEC62196 Flexing Under Mechanical Load Tester for EV Connector Screw Terminals

Product Overview

The Terminal Mechanical Flexing Test Equipment This IEC-compliant flexing test bench is a dedicated safety verification instrument for EV charging screw clamping terminals, widely adopted by EV charging testing laboratories, certification bodies, coupler manufacturers and quality inspection institutes across Europe, Southeast Asia, Latin America and the Middle East.

It strictly implements IEC 62196-3:2026 Clause13 and IEC 62196-1:2022 Clause13.3.1 (Figure12 & Table5). It simulates cyclic mechanical stress on terminals during daily charging plugging & unplugging, to validate two core performance indicators: Whether the clamping screw terminal structure will cause excessive damage to internal conductors; Whether the terminal assembly can withstand repeated flexing load without failure under normal service cycles.

Users can preset flex cycles before starting the experiment. Once the target cycle count is reached, the unit will automatically halt and trigger an audible & visual alarm, unattended operation is supported to boost lab testing efficiency. The unit comes with a manual lifting trolley, which greatly reduces labor risk when installing heavy test masses, convenient for fast weight replacement between different wire gauge tests.

Key Features & Advantages

1. Full IEC Standard Alignment:Test fixture layout fully replicates Figure12 of IEC62196-1, test data can be directly used for CB, CE certification reports for EV charging connectors.
2. Wide Wire Gauge Coverage:Covers conductor area 1.0 mm² ~ 630 mm², compatible with low-current small terminals and heavy-duty DC charging large-gauge cables.
3. Safe & Labor-Saving Design:Custom manual lift cart included. Heavy masses up to 70.3kg can be installed safely, avoiding dropping hazard in lab operation.
4. Stable Cycle Control & Auto Alarm Stop:Digital preset cycle, stable rotation speed (10±2rpm). Automatic stop + alarm, suitable for overnight unattended durability test.
5. Easy Calibration & Maintenance:Modular structure, independent bushing replacement, easy for third-party metrology calibration.
