[0002] Wire-wound resistors are a type of fixed resistor. A wire-wound resistor is composed of a resistance wire wound around an insulating skeleton. The resistance wire is generally made of alloys such as nickel-chromium and manganese-copper with a certain resistivity. The insulating skeleton is made of materials such as ceramics, plastics, and metals coated with an insulating layer in various shapes such as tubular and flat. The resistance wire can be wound around the skeleton in one layer as needed, or multiple layers can be wound, or a non-inductive winding method can be used, etc. Wire-wound resistors are mainly applicable for use as voltage-dividing, voltage-dropping, current-dividing, and load resistors in AC and DC circuits of precision instruments, telecommunications instruments, electronic equipment, etc.

The efficiency of manually braiding resistors is low, and the cost of braiding by large machines is too high and is only applicable to scenarios of mass production. In scenarios such as laboratories where there is a small demand for braided resistors, there is a need for a high-efficiency resistor wire braided frame structure without the use of large machines.
