DIN VDE 0620-1 Bild 14 Example Device for Measuring Contact Force of Lateral Protective Contacts

This DIN VDE 0620-1 Bild 14 example device is designed to measure the contact force of lateral protective contacts in sockets, complying with DIN VDE 0620-1 Bild 14 (2021-02 edition). It ensures that protective conductor contacts maintain adequate contact pressure and do not deteriorate during intended use. Featuring a structured design with rotatable levers and precise marking mechanisms, the device delivers accurate and reliable force measurement results, serving as a key tool for quality control and compliance verification in electrical socket production.

Specifications:

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

Test Procedures:

• Prepare the test socket and ensure the device is clean and properly assembled.
• Position the socket in the designated location on the device to align with the test mechanism.
• Adjust the device so that the lower ends of the two rotatable levers (L) press against the lateral protective contacts of the socket.
• Align the marking indicators (a and b) on the upper ends of the levers with the marks on the fixed part of the device, confirming that the distance between the lever tips (F) and the device’s center line is 16 mm ± 0.1 mm.
• Apply force to the hooks (H) at the upper ends of the levers in accordance with standard requirements.
• Measure and record the contact force exerted by the lateral protective contacts during the test process.
• Evaluate whether the measured contact force meets the required standards.
