VDE0620-1:2021 Figure Bild 11 Transverse Stress Test Gauge

GNGPL-6211BILD Transverse Stress Test Gauge is precisely manufactured per Figure 11 of DIN VDE 0620-1:2021, matching Clause 13.14. It is dedicated equipment for lateral mechanical strength test of German standard plug pins. Its pins are finished with roughness Rz3~Rz5 and all dimensions comply with standard tolerances. It applies accurate lateral force on plug pins to simulate extrusion force during plug insertion/removal and accidental collision, checking pin firmness and judging failure such as loosening, bending and displacement. It is widely adopted for plug type test, incoming inspection and structural reliability R&D verification.

Specifications:
• Standard: DIN VDE 0620-1:2021, Figure 11, Lateral Load Test Fixture (Clause 13.14)
• Pin Surface Roughness: Rz 3 ~ Rz 5
• Pin Diameter: Φ4.0±0.06 mm
• Force Applying Rod Diameter: Φ5 mm
• Key Dimension Tolerance:
– Pin center distance: 19±0.2 mm
– Pin exposed length: 19±0.5 mm
– Distance from force fulcrum to reference surface: 8±0.5 mm
– Total force arm length: 42±0.5 mm
– Base width 15±0.5 mm, base height 30±0.5 mm
• Structure: Integrated positioning base + double locating pins + single-point force application rod

Test Procedures:
• Pre-inspection: Check pin roughness and overall dimensions, ensure no deformation and burrs within drawing tolerance.
• Sample Mounting: Clamp tested plug onto two locating pins tightly, make plug end face fit reference surface without offset.
• Lateral Force Application: Apply specified vertical lateral force on the end of Φ5 rod and keep force for required duration.
• Result Inspection: Remove external force, check pins for bending, loosening, deflection or detachment; samples without structural damage are qualified.
• Retest & Record: Repeat tests on batches, record critical deformation force for structural optimization.

Applications:
• Third-party Labs: Mechanical type certification test for German plugs in VDE, TÜV, CQC laboratories;
• Power Cord Manufacturers: Factory reliability sampling inspection and incoming structural test for EU plugs;
• Connector R&D Enterprises: Verification of pin reinforcement schemes and bending resistance of new materials;
• Quality Supervision Institutions: Import & export plug spot check and defective product failure analysis;
• University Labs: Scientific experiments on mechanical durability of electrical connectors.
