[0002] Existing copper-core PVC insulated flexible wires are susceptible to damage from external pulling during use. Internal damage and malfunctions are difficult to repair, often requiring replacement of the entire wire at high cost. A Chinese patent (application number CN202223449129.X) discloses a "copper-core PVC insulated connecting flexible wire," comprising a protective sleeve, a wear-resistant layer, and a second insulation layer. The wear-resistant layer is adhered to the inner periphery of the protective sleeve, and the second insulation layer is adhered to the inner periphery of the wear-resistant layer. Several support sleeves are embedded in the inner periphery of the second insulation layer, each with a support post at one end. The periphery of one end of the support post slides against the inner periphery of the support sleeve, and a heat-conducting layer is embedded at one end of the support post. This invention, through its protective sleeve, support sleeves, and support post structure, improves the protection of the wire's internal structure, buffers external pressure during operation, prevents damage to the internal structure, enhances the wire's protective performance, and extends its service life. However, electrical wires are difficult to withstand external pulling forces and are prone to damage caused by such forces; when electrical wires malfunction, they are not easy to repair and replacement costs are high.
