What is a power cord bending testing machine?
In today's era of rapid technological development, the quality and durability of electronic products have become the focus of attention of consumers and manufacturers. As an important part of electronic equipment, the durability and safety of power cords directly affect the overall performance of the product. The power cord bending testing machine is a device specially used to test the bending resistance of power cords. It is widely used in quality inspection links in electronics, home appliances, automobiles and other industries. This article will introduce in detail the definition, working principle, application fields and comparison of popular models in the market of power cord bending testing machines.
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 setting specific bending angles, frequencies and times, it detects whether the power cord will break or have insulation damage after long-term use. This device is an important tool to ensure that power cords comply with international standards (such as IEC, UL, etc.).
2. Working principle of power cord bending testing machine
The power cord bending testing machine drives the fixture through a motor to repeatedly bend the power cord within a set angle range. During the test, the device records the number of bends and monitors the conductive properties of the power cord. When the power cord is broken or the resistance is abnormal, the device will automatically stop and alarm so that the cause of the failure can be analyzed in time.
| Core components | Function description |
|---|---|
| Drive motor | Provide power to control bending frequency and angle |
| Fixture device | Fixed power cord to simulate actual bending scenarios |
| counter | Record the number of bends and stop when reaching the preset value |
| Resistance monitoring module | Detect the continuity status of the power cord to determine whether it has failed |
3. Application fields of power cord bending testing machine
Power cord bending testing machines are widely used in the following industries:
| Industry | Application scenarios |
|---|---|
| Electronic manufacturing | Test the durability of mobile phone charging cables, headphone cables, etc. |
| Home appliance industry | Evaluate the life of power cords such as rice cookers and vacuum cleaners |
| Automotive industry | Test the performance of vehicle charging cables and battery cables |
| Quality inspection agency | Third-party certification testing based on international standards |
4. Comparison of popular models
The following is a comparison of common power cord bending testing machine models on the market and their main parameters:
| Model | Maximum bending angle | Test speed | Applicable wire diameter range |
|---|---|---|---|
| DX-2000 | 180° | 10-60 times/minute | 0.5-6mm |
| QC-360 | 360° | 5-30 times/minute | 1-10mm |
| ProTest-100 | 90° | 20-100 times/minute | 0.3-5mm |
5. Conclusion
The power cord bending testing machine is a key equipment to ensure the quality of electronic products, and its test results directly affect the market competitiveness of the product. As industry standards continue to improve, this equipment will develop in the direction of intelligence and high precision in the future. When purchasing, enterprises need to select suitable models and functional configurations based on their own needs.
