How do I find the right constant force spring for my cable accessories?
How to determine the constant force spring’s constant spring force, magnetic properties, corrosion resistance, etc. is the first consideration for cable accessory manufacturers and customers.
Constant force springs are used in the same environment as cable accessories and are generally wrapped externally with some strip material to prevent axial displacement along the cable. In use, wrapped around the entire joint or inside the terminal, there is no direct contact with moisture, but it is easy to contact moisture when the sheath is broken, plus the heat generated when the cable is running and various internal insulation and sheathing materials such as escaping gas, forming a very harsh small environment, thus the corrosion resistance of constant force springs in cable accessories is very demanding.
The corrosion resistance of constant force springs is related to the material and processing technology. Constant force springs for cables are generally selected from stainless steel 301, cold processing when the tensile strength and hardness increased, non-magnetic, but magnetic after cold processing, after heat treatment can eliminate the magnetism, the surface will also become a light yellow.
