| 发明名称 | Differential signal cable and production method therefor | ||
| 摘要 | A differential signal cable is composed of two inner conductors, an insulator, which covers the two inner conductors separately or together, and an outer conductor, which covers a circumference of the insulator. When measured in a cable length of 1 m, an effective capacitance difference ΔX represented by Formula (1) below is not greater than 0.2 percent of an average value C of capacitances of the two inner conductors, ΔX=ΔC+ΔL/Z02 (1), where ΔC is a difference in capacitance between the two inner conductors, ΔL is a difference in inductance between the two inner conductors, and Z0 is a reference impedance (50 ohms). | ||

| 主权项 | 1. A differential signal cable, comprising: two inner conductors; an insulator, which covers the two inner conductors separately or together; and an outer conductor, which covers a circumference of the insulator, wherein when measured in a cable length of 1 m, an effective capacitance difference ΔX represented by Formula (1) below is not greater than 0.2 percent of an average value C of capacitances of the two inner conductors, ΔX=ΔC+ΔL/Z02 (1),where ΔC is a difference in capacitance between the two inner conductors, ΔL is a difference in inductance between the two inner conductors, and Z0 is a reference impedance (50 ohms). | ||
