Thermoplastic elastic wire can effectively extend the service life of the terminal

The terminal serves as a critical interface between wires and cables, where its functionality is closely tied to the performance of these components. When paired with high-quality wires and cables, the terminal’s capabilities can be fully realized, resulting in enhanced stability and extended service life. This synergy ensures smoother current flow and improved reliability. Consequently, the flexibility of wires and cables becomes a key consideration, as it directly impacts their ability to perform optimally under various conditions. In applications involving terminal blocks, rubber is frequently chosen as the material for insulation and sheathing due to its exceptional flexibility, excellent abrasion resistance, and superior weathering properties. However, rubber's complex processing requirements and relatively high costs present certain challenges. Over the past few years, thermoplastic elastomers (TPEs) have gained significant traction as an alternative. These materials allow manufacturers to produce flexible, cable-like products using existing plastic processing equipment, offering both cost efficiency and versatility. Terminals demand specific attributes from the wires they connect to, yet they remain adaptable to diverse materials. Among the commonly used options are ethylene-propylene TPEs, polyester TPEs, polyurethane TPEs, nitrile-polyvinyl chloride elastomers, and fluorine-containing TPEs. The production of TPEs typically involves two primary methods: mechanical blending of rubber with thermoplastics of similar solubility indices, followed by dynamic cross-linking; or block copolymerization of two distinct prepolymers, where one segment provides elasticity while the other forms cross-links to create a thermoplastic elastomer, such as polyurethane elastomers. By leveraging the ease of processing and flexibility offered by thermoplastic elastomers, terminals can maximize their current-carrying capacity. This approach is particularly advantageous for creating specialized cables tailored to meet specific market demands. The integration of terminals with custom-wired solutions not only enhances equipment performance but also brings substantial advantages to manufacturers by streamlining assembly processes and reducing costs. Moreover, the dual connection between terminals and wires/cables creates opportunities for innovation. By optimizing this interaction, equipment manufacturers can achieve greater efficiency, durability, and adaptability in their products. As industries continue to evolve, embracing advanced materials like thermoplastic elastomers will play a pivotal role in driving progress and meeting future technological needs.
