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 fully complies with Clause 12.3.12 Figure 12 of IEC 60884-1:2022 (GB/T 2099.1-2021) and Clause 12.3.12 Figure 11 of IEC 60669-1:2017 (GB/T 16915.1-2024). After the wires are connected according to the standard, a dflection test is performed on the wires and their voltage drop is measured to assess the clamping capacity and contact performance of the screwless terminals, thereby verifying whether the screwless terminals can be clamped even if they are deflected during the wiring process and the deflection force has been transmitted to the clamping parts after being connected to the single-core hard wires.

Standard: 
IEC 60884-1 (GB/T 2099.1) “Plugs and socket-outlets for household and similar purposes – Part 1: General requirements” Clause 12.3.12 Figure 12
IEC 60669-1 (GB/T 16915.1) “Switches for household and similar fixed-electrical installations – Part 1: General requirements” Clause 12.3.12 Figure 11

Specification:
• Operating Mode: Manual
• Bending Angle: 0-360°, Graduation: 10°
• Bending Direction: Towards any one of the 12 directions, each differing by 30°±3°
• Weights: 0.25 N, 0.5 N, 1.0 N
