SHIELDED CABLE ASSEMBLY

摘要

A wire cable assembly capable of transmitting signals at speeds of 5 Gigabits per second over a single pair or conductors. The cable has a characteristic impedance of 95 Ohms and can support transmission data according to either USB 3.0 or HDMI 1.3 performance specifications. The wire cable includes a pair of conductors, a shield surrounding the conductors, and a dielectric structure configured to maintain a first predetermined spacing between the conductors and a second predetermined spacing between said the conductors said shield. The shield includes an inner shield conductor enclosing the dielectric structure, a ground conductor external to the inner shield conductor, extending generally parallel to the pair of conductors, an outer shield conductor enclosing the inner shield conductor and the ground conductor.

1. An assembly configured to transmit electrical signals, comprising:
a wire cable having
a first inner conductor and second inner conductor;a shield surrounding the first inner conductor and the second inner conductor; anda dielectric structure configured to maintain a first predetermined spacing between the first inner conductor and the second inner conductor and a second predetermined spacing between said the first inner conductor and the second inner conductor and said shield, wherein the shield comprises
an inner shield conductor at least partially enclosing the dielectric structure, thereby establishing a characteristic impedance of the wire cable,a ground conductor external to the inner shield conductor, extending generally parallel to the pair of first and second inner conductors and in electrical communication with the inner shield conductor, andan outer shield conductor at least partially enclosing the inner shield conductor and the ground conductor and in electrical communication with the inner shield conductor and the ground conductor.
