US 2026/0229387 A1 · Cold-Resistant Shielded Wire Assembly for Multi-Functional Power and Signal Transmission in Harsh Environments

Abstract

The present invention relates to a cold-resistant, shielded wire assembly designed for multi-functional power and data signal transmission in harsh and demanding environments. The wire assembly features conductors composed of tinned copper strands insulated with polyvinyl chloride (PVC) material capable of withstanding temperatures ranging from −40° C. to +105° C. An aluminum foil shielding layer with a 125% overlap rate minimizes electromagnetic interference (EMI), while a semi-matte PVC outer jacket provides enhanced durability, flexibility, and resistance to environmental factors such as moisture, abrasion, and chemicals. The assembly includes fool-proof connectors to ensure proper alignment during use and supports HDMI compatibility for audiovisual systems. Printed identification markings indicate compliance with UL and AWM standards, as well as temperature and voltage ratings, facilitating installation and maintenance. Suitable for industrial, automotive, aerospace, medical, outdoor, and consumer electronic applications, the invention provides a reliable, versatile, and robust solution for modern power and signal transmission challenges.
