If you have ever used a fixed line telephone, you must be familiar with its crimped earpiece cable - it will grow longer as soon as you pull it, and will automatically bounce back as soon as you let go. This is the most common spiral cable, also known as spring wire. The wire that can be stretched and retracted like a spring is a kind of equipment connecting wire that uses scalability to work.
Unlike ordinary flat and easily wound straight-line wires, spiral cables wind high-quality copper wires into spiral shape, and the outer layer is wrapped with durable insulation (such as PVC and pur materials). Its biggest feature is that it can stretch flexibly and rebound automatically: it can be pulled to several times its original length when in use, and quickly shrink back to a compact spiral shape when not in use, saving space while maintaining a clean environment.
More importantly, spiral cable is more durable than ordinary wire. It is specially designed to withstand repeated tension, bending and torsion, and is not easy to break even if it is frequently used. This makes it very suitable for scenes where devices need to move back and forth, wires need to follow and cannot be damaged.
Advantages of spiral cable
- Space saving: compact spiral shape, bid farewell to messy wires, and make your products more concise and beautiful.
- Durable and durable: resistant to repeated stretching and bending, reducing the maintenance cost of your product.
- Wide applicability: it is suitable for indoor and outdoor, high and low temperature environment, and has a variety of materials (PUR material is oil-resistant and wear-resistant, suitable for industrial and outdoor use; PVC material is cost-effective and suitable for daily scenes)
So where is spiral cable applied?
1. Daily consumer electronics
Fixed telephone handset line and multimeter test probe line that can be seen in almost every home or office
And some mobile power charging lines, etc
2. Industrial automation
In factories, spiral cables are widely used in industrial robots (connecting the power and signals of mechanical arms), CNC machine tools, logistics sorting equipment, and cleaning equipment (such as vacuum cleaners and floor washers). The moving parts of these equipment need to run back and forth. The spiral cable can follow the movement flexibly, without affecting the operation of the equipment, and at the same time, avoiding the winding and damage of wires.
3. Automotive industry
The clock spring cable in the steering wheel is connected to the airbag and multi-function buttons - when you turn the steering wheel, the cable will stretch and rebound with the rotation to ensure that the airbag and buttons always work normally
4. Medical equipment
Spiral cable will also be used for medical equipment such as monitors, surgical instruments and mobile diagnostic equipment. These devices need to be moved frequently in the hospital, and spiral cables can keep the wires clean
