[0002] Electronic wires are wires or cables used to connect electronic components, transmit electrical signals and electricity, and are usually composed of metal conductors and insulation layers. Electronic wires are widely used in electronic equipment, communication equipment, automobiles, household appliances and other fields. Electronic wires may suffer some damage during the bending process. These damages include: frequent bending can cause fatigue fracture of metal wires, especially at the bends where fracture points are prone to occur. When bending, the insulation layer may be subjected to excessive tension or compression, causing the insulation layer to rupture, thereby affecting the insulation performance of the wire. Long-term bending may cause the shape of the wire to change, affecting the connection and transmission performance of the line. Therefore, when producing electronic wires, it is usually necessary to test the bending life of the electronic wires. Electronic wire bending test equipment is usually used to test the durability and performance of electronic wires during the bending process. This equipment can simulate the bending of electronic wires during use, thereby evaluating their durability and life.
