Product Overview:
The pin bending test device is a specialized equipment used to test the mechanical strength and bending resistance of plug pins (including insulation sheaths). The core is based on standards such as GB 1002-2024 (corresponding to IEC 60884-1) and AS/NZS 3112, simulating the bending of pins under external forces during insertion, removal, and transportation to verify their structural integrity and conductivity reliability. The following will explain the core information, testing process, and selection points.
core purposeEvaluate the bending resistance of plug pins (especially those with insulation sheaths) to ensure that the pins are not broken, loose, or have insulation damage after bending, and that the conductive path is normal.
Main standards：
National standard: GB 1002-2024 "plugs and sockets for household and similar purposes - Part 1: General requirements", Article 5.3 (Figure 26).
International/regional standards: IEC 60884-1, AS/NZS 3112, BS 1363-1, JIS 8303, etc.
Sample preparationTake 3 qualified plug products and record the initial state (appearance, conductivity).
Clamping and positioningFix the plug in the fixture, adjust the swing fixture to the center of the pin, and set the force application position (such as 14 mm from the mating surface).
Parameter SettingsSet the bending speed (e.g. 5 mm/s), stroke (e.g. 10 mm), number of times (e.g. 50 times), and single-sided/double-sided bending mode on the touch screen.
Start the testThe device automatically runs according to the set parameters and displays real-time counting and status.
Result determination
Appearance: The plug is not broken or significantly deformed, and the insulation sheath is not damaged or detached.
Electrical: The connection between the plug and the conductor is reliable, the conductivity is normal, and there is no open circuit/short circuit.
If any failure occurs, it is judged as unqualified and the structure or materials need to be optimized.
Key selection points
Prioritize selecting models that meet the standards of the target market to ensure compliance.
Pay attention to driving accuracy (stepper motor+ball screw is superior to ordinary motor) and control stability.
Select single/multiple workstations based on the detection volume, and export companies are recommended to choose models that are compatible with multiple standards.
Precautions for use
During clamping, avoid damaging the insulation or pins of the plug to ensure accurate positioning and prevent testing errors.
Regularly calibrate the bending stroke, speed, and force values to ensure data traceability.
Clean the fixtures and actuators after the experiment to avoid dust affecting the accuracy of the next test.
