IEC 60884-1 IEC 60669-1 Clause 12.3.12 Screwless Terminal Deflection/Bending Test Device

The JCY-2 Screwless Terminal Deflection/Bending Test Device is a precision-engineered apparatus designed for the quantitative assessment of threadless terminal connection integrity in accordance with international electrical safety standards. This specialized test equipment simulates mechanical bending stresses encountered during field installation by applying controlled bending forces in specified orientations to connected conductors.

The device implements the standardized test methodology defined in Clause 12.3.12 of IEC 60884-1:2022 (Plugs and socket-outlets for household and similar purposes – Part 1: General requirements) and Clause 12.3.12 of IEC 60669-1:2017 (Switches for household and similar fixed electrical installations – Part 1: General requirements). During test execution, the apparatus simultaneously measures voltage drop across the terminal connection while applying bending moments, providing objective data for evaluating terminal clamping force retention and contact stability under mechanical stress conditions.

This verification process confirms that terminal connections maintain electrical continuity and mechanical integrity when bending forces are transmitted to clamping components, ensuring compliance with safety requirements for electrical installations.
