1-1579018-4 is a crimping terminal manufactured by TE Connectivity for solderless electrical assembly applications. The terminal functions by compressing a wire barrel tightly around stripped wire strands to form a homogeneous metal connection without requiring solder, heat, or flux. The product is engineered to meet industry certification standards including vibration testing (16 hours of intense vibration exposure), crimp tensile strength requirements per MIL-T-7928, dielectric strength testing, and voltage drop testing to ensure electrical resistance stability. The terminal must be crimped using tools from the same manufacturer to guarantee quality and meet industry certifications. This crimping terminal is widely used in industrial systems and electrical assembly applications where reliable, low-cost solderless connections are required, offering lasting crimp performance when properly applied with matched tooling.
