To meet these requirements, Sinuo provided the Charging Interface Mechanical Load Test Device, a high-performance solution developed specifically for EV connector and socket mechanical safety testing.
The device integrates adjustable clamping mechanisms, precision weight configuration systems, and standardized test layouts, ensuring accurate, repeatable test results and full compliance with IEC 62196-1, GB/T 20234.1, and GB 11918.4 standards.
Key Features & Advantages
1.Full Compliance with International Standards
The device is designed to meet IEC 62196-1:2022, with compatibility for major global standards including GB/T 20234.1 and GB 11918.4. It supports all required tests: mechanical load testing, locking device testing, and insertion/withdrawal force testing, ensuring the client’s products meet regulatory requirements for both domestic and international markets.
2. Flexible and Versatile Testing Capabilities
- Adjustable Clamping System: The device features an adjustable clamp that switches between vertical and horizontal orientations, accommodating various connector types and sizes. The hanging ring design simplifies operation, improving test efficiency.
- Precise Load Configuration: It supports a wide range of test loads, including 165N, 300N, 440N, 660N, and 750N withdrawal forces, with weight combinations tailored to different rated currents (AC/DC). The insertion force test uses standard weights (9.2kg for AC guns, 13.2kg for DC guns) plus a 0.8kg impact weight to simulate real-world use conditions.
- Comprehensive Test Modes: The device performs all required tests: mechanical load tests (60s holding time, 4 directions), locking device tests, and insertion/withdrawal force tests, covering every aspect of connector mechanical safety.
3. User-Friendly and Reliable Operation
The test station features a single-station design with S136 gauge components (±0.01mm tolerance, 0.8µm smoothness) for high precision. The hydraulic cylinder-driven system ensures stable weight lifting/lowering, with manual control for test timing and frequency. The working environment range (5-35°C, 30-90% humidity) ensures consistent performance in lab conditions.
