Description

Technical Field

[0001] This utility model relates to the field of tin-plated copper stranded wire technology, specifically a tin-plated copper stranded wire with a reinforced inner core. Background Technology

[0002] Tinned copper wire is a type of conductor with a layer of tin alloy plated on the surface of copper wire. It has excellent electrical conductivity and mechanical strength and is widely used in the connection of various electrical equipment and electronic products. Tinned copper stranded wire is made by drawing copper products into wires, tinning the drawn copper wires, and then stranding the tinned copper wires together with other materials.

[0003] The existing publication number CN222126067U discloses a tinned copper stranded wire with a reinforced inner core, relating to the field of tinned copper wire technology. It includes a copper wire comprising a main copper wire at the center and multiple sets of side copper wires spirally stranded on the outer wall of the main copper wire. The main copper wire is disposed inside a reinforcing tube, and the outer wall of the reinforcing tube is fitted with an alloy lead sleeve. A second outer sheath is connected to the outer wall of the alloy lead sleeve through a fiber layer. The reinforcing tube has a double-layered annular hollow structure. By placing the main copper wire inside the reinforcing tube, the reinforcing tube provides stable support at the center of the copper stranded wire, facilitating stable stranding of the multiple sets of side copper wires on the outer wall of the main copper wire. Furthermore, by providing a closed cavity and a cork plug inside the reinforcing tube, the stranding effect of the tinned copper stranded wire is improved, enhancing its structural strength and tensile strength, thus extending its service life.

[0004] While existing technologies have improved the tensile strength of tin-plated copper stranded wire to some extent, the tensile strength is limited by relying solely on the reinforcing tube. Therefore, we propose a tin-plated copper stranded wire with a reinforcing core. Summary of the Invention
