What is a power cord bending testing machine?
In today's era of rapid technological development, power cords are an important part of electronic equipment, and their quality and durability have attracted much attention. The power cord bending tester is a device specially used to test the durability and reliability of power cords under repeated bending. This article will introduce in detail the definition, working principle, application fields and related technical parameters of the power cord bending testing machine.
1. Definition of power cord bending testing machine
The power cord bending tester is a testing device that simulates the repeated bending of power cords during actual use. By conducting multiple bend tests on the power cord, its durability and reliability are evaluated to ensure that it meets relevant industry standards and safety requirements.
2. Working principle of power cord bending testing machine
The power cord bending testing machine uses a mechanical device to simulate the bending action of the power cord in usage scenarios such as plugging, unplugging, and moving. During the test, the power cord is fixed on the testing machine and driven by a motor to bend it repeatedly within a certain angle. The number of bends is recorded during the test until the cord breaks or performance degrades.
| test items | Test method | Test standards |
|---|---|---|
| Number of bends | Repeatedly bend until it breaks | IEC 60884 |
| bending angle | Usually 90 degrees or 180 degrees | UL 817 |
| Test speed | 10-30 times/minute | GB/T 2099 |
3. Application fields of power cord bending testing machine
Power cord bending testing machines are widely used in the following fields:
1.Electronic equipment manufacturing: Used to test the durability of power cords for mobile phones, computers, home appliances and other equipment.
2.Automotive industry: Test the reliability of the car's internal power cord in the vehicle's vibration environment.
3.Aerospace: Evaluate the bending performance of aircraft power cords in extreme environments.
4.Quality inspection agency: As a third-party testing device, it ensures that the power cord complies with national safety standards.
| Industry | Test focus | Related standards |
|---|---|---|
| Home appliances | Plug connection durability | IEC 60320 |
| car | Bending in a vibrating environment | ISO 6722 |
| Aviation | Performance in extreme temperatures | MIL-STD-202 |
