DIN VDE 0620-1 Bild 14 Lateral Protective Contact Force Measurement Device

This DIN VDE 0620-1 Bild 14 Lateral Protective Contact Force Measurement Device is engineered to measure the contact force of lateral protective contacts in electrical sockets, ensuring full compliance with DIN VDE 0620-1 Bild 14 (2021-02 edition). The device verifies that protective conductor contacts maintain specified contact pressure and do not experience premature degradation during normal operation. Featuring a precision-engineered design with rotatable levers and calibrated marking mechanisms, this instrument delivers accurate and repeatable force measurement results, serving as an essential tool for quality control departments and compliance verification in electrical socket manufacturing.

Specifications

• Applicable Standards: DIN VDE 0620-1 Bild 14 (2021-02 edition)
• Core Function: Measurement of contact force for lateral protective contacts in electrical sockets
• Structural Components: Two rotatable levers (L), force application hooks (H), calibrated marking indicators (a and b), fixed alignment structure with reference marks, standardized spacing plate
• Critical Dimensional Parameter: Distance between lever tips (F) and device center line: 16 mm ± 0.1 mm
• Application Scope: Fixed electrical sockets for household and similar applications

Test Procedures

1. Prepare the test socket specimen and verify the measurement device is properly calibrated and assembled according to standard requirements.
2. Position the socket specimen in the designated test location, ensuring proper alignment with the measurement mechanism.
3. Adjust the device configuration so the lower ends of both rotatable levers (L) engage precisely with the lateral protective contacts of the socket.
4. Align the marking indicators (a and b) on the upper lever ends with the reference marks on the fixed structure, confirming the distance between lever tips (F) and device center line measures 16 mm ± 0.1 mm.
5. Apply standardized force to the hooks (H) at the upper lever ends in accordance with DIN VDE 0620-1 Bild 14 requirements.
6. Measure and document the contact force exerted by the lateral protective contacts throughout the test sequence.
7. Evaluate whether the measured contact force values comply with the specified requirements in the applicable standard.
