Screw Terminal Strength Tester Description
Terminal Tester IEC 62196-1 Figure 7 Screw Terminal Strength & Durability Testing Machine
The Screw Terminal Strength Tester is a specialized mechanical durability testing system designed to evaluate the clamping strength and long-term reliability of screw terminals in vehicle plugs, socket-outlets and connectors. Manufactured in full compliance with IEC 62196-1:2022 Clause 13.3.1 (Figure 12 & Table 3), the tester applies controlled rotating mechanical loads to simulate repeated flexing stress under normal operating conditions, ensuring terminals maintain secure wire retention throughout their service life.
Testing Principle
The tester mounts the terminal specimen on a rotating fixture and applies a preset weight while performing continuous rotation at (10 ยฑ 2) r/min. The system records the number of cycles and automatically stops when the preset count is reached or when a fault condition is detected, providing accurate assessment of terminal clamping strength and wire damage resistance as required by the standard.
