US Patent 10424420 Drain aligned cable for next generation speeds

A dual axial cable is provided with adjacent and substantially parallel first and second wires. Each wire is formed from electrical conductor surrounded by a respective first and second electrical insulator having lengthwise drain alignment groove on outward side and having respective first and second inward sides of interlocking structure. First and second inward sides of interlocking structure of first and second electrical insulators mutually engage to prevent relative transverse displacement of first and second wires. The interlocking structure maintains the planar alignment of lengthwise drain alignment grooves and electrical conductors of first and second wires. First and second drain conductors are received respectively in lengthwise drain alignment grooves of first and second electrical insulators and run adjacent and substantially parallel to first and second electrical conductors. Drain conductors are maintained in parallel alignment to electrical conductors to provide shielding benefits.
