The function of spiral cables
Spiral cable (also known as spring cable or slingshot wire) is a special type of cable with flexibility and rapid rebound characteristics. Its core function is to provide stable and reliable electrical connections for mobile devices. According to different application scenarios, its main functions can be summarized as follows:
Power and signal transmission in dynamic environments
Youdaoplaceholder0 Adaptive extension and contraction
It supports continuous power supply and signal transmission of the equipment during telescopic and reciprocating movement. The extension length can reach 3.5 to 4 times the original spiral length, and it will automatically rebound and return to its original state after the external force is removed.
It is widely applied to cranes, production line conveyor belts, lifting platforms, construction machinery and other equipment that need to be moved frequently.
Youdaoplaceholder0 Resistance to mechanical stress
It can withstand complex working conditions such as stretching, friction and rapid bending, has a long service life (up to 3 million cycles), and is not prone to core wire cracking or sheath damage.
It is applicable to scenarios with high requirements for mechanical strength, such as agricultural equipment, CNC machine tools, and laser cutting machines.
Stable connection between rotating parts
Youdaoplaceholder0 Automotive safety systems
As the hairspring of the steering wheel, it connects the airbag and the steering column wiring harness to ensure the stable transmission of signals from the airbag detonation circuit, the horn and the multi-functional buttons when the steering wheel is turned.
If damaged, it will cause the airbag fault code or functional failure.
Youdaoplaceholder0 Industrial robot control
The robot drag chain cable and spiral cable are used in conjunction to provide power and control signals for the rotation of the mechanical arm joint.
Reliable performance in special environments
Youdaoplaceholder0 Chemical and weather resistance
The PUR material sheath is resistant to oil stains, hydrolysis, weak acids, weak alkalis and ultraviolet rays, and is suitable for clean or corrosive environments such as medical equipment and semiconductor manufacturing.
Youdaoplaceholder0 Anti-electromagnetic interference
Shielded helical cables can suppress electromagnetic interference and ensure the accuracy of signal transmission for precision instruments such as medical equipment and meters.
Optimize the layout and maintenance of equipment
Youdaoplaceholder0 Efficient space management : The spiral structure is convenient for storage, prevents cable tangling, and enhances the aesthetic appearance and operational safety of the equipment.
Automobile spiral cable (also known as steering wheel hairspring, clock spring or spiral cable) is a special electrical connection component specially designed to adapt to the rotational movement of the car steering wheel. Its core function is to ensure the continuous stability of the electrical connection when the steering wheel rotates. The following is a summary of the key information:
Core function
Youdaoplaceholder0 Dynamic circuit connection : During the 360° rotation of the steering wheel, keep the airbag, horn button, multi-function button and other electrical appliances on the steering wheel and the electrical system below the steering column powered on and signal transmitted to avoid entanglement or breakage of the circuit.
Youdaoplaceholder0 Airbag protection : It is particularly crucial to provide a reliable current to the airbag to ensure it triggers instantly in the event of a collision, and the internal wiring is designed to withstand long-term torsion without damage.
Structural characteristics
Youdaoplaceholder0 Two-stage design :
Youdaoplaceholder0 Rotatable section : Connects electrical components on the steering wheel (such as airbag modules).
Youdaoplaceholder0 Fixed section : Connects the body wiring harness below the steering column.
Youdaoplaceholder0 Elastic material : The conductor is usually made of multiple strands of fine copper wire (high flexibility), and the insulation and sheath are made of wear-resistant, oil-resistant, and high and low temperature resistant materials such as polyurethane (PUR) (-40 ° C to +125 ° C) to ensure long-term reliability.
Youdaoplaceholder0 Helical shape : Formed into a spring-like structure through hot working, with an extension ratio of 1:3 to 1:4, suitable for large turns of the steering wheel.
Application scenarios
Youdaoplaceholder0 Airbag system : Core transport path, keeping airbags on standby in real time.
Youdaoplaceholder0 Steering wheel electrical appliances : Connect signal lines for horn, multimedia control, cruise buttons, etc.
Youdaoplaceholder0 Trailer power transmission : Seven-core helical cable for trailer power supply, supporting frequent telescopic movement.
Impact of malfunction
If damaged, it may cause:
The airbag fault light is on and the airbag fails.
The horn is malfunctioning and the steering wheel buttons are unresponsive.
It is necessary to check the plug connection or replace the helical cable assembly.
