Problems solved by technology

However, manufacturing tolerances in conductors and insulators can lead to performance degradation in high-speed signal cables
For example, air pockets formed by cable shielding wraps can cause performance degradation in the form of electrical signal timing skew due to differences in the effective dielectric surrounding the first and second signal conductors

Embodiment Construction

[0010] figure 1 is a perspective view of a portion of cable 100 formed according to an embodiment. Cable 100 may be used for high-speed data transmission between two electrical devices, such as electrical switches, routers, and / or host bus adapters. The cable 100 has a shielding structure configured to control capacitance and inductance relative to the signal conductors to control signal skew in the cable 100 for high speed applications.

[0011] The cable 100 includes a conductor assembly 102 . The conductor assembly 102 is retained within the outer jacket 104 of the cable 100 . The outer jacket 104 surrounds the conductor assembly 102 along the length of the conductor assembly 102 . exist figure 1 In , for clarity, conduit assembly 102 is shown protruding from outer sheath 104 in order to illustrate various components of conductor assembly 102 that would otherwise be blocked by outer sheath 104 . However, it should be appreciated that the outer jacket 104 may be strippe...

Abstract

An electrical cable (100) includes a conductor assembly (102) having a first conductor (110), a second conductor (112) and an insulator (114) surrounding the first conductor and the second conductor.The insulator has an outer surface (116) having an RMS roughness of less than 1.0 micrometers. A cable shield (120) provides electrical shielding for the first and second conductors and has a metallized conductive layer (122) on the outer surface of the insulator.

Description

technical field [0001] The subject of this article relates generally to the shielding effectiveness of signal transmission cables and signal conductors. Background technique [0002] Shielded cables are used in high-speed data transmission applications where electromagnetic interference (EMI) and / or radio frequency interference (RFI) are involved. Electrical signals routed through shielded cables radiate less EMI / RFI to the external environment than electrical signals routed through unshielded cables. Additionally, electrical signals transmitted over shielded cables are better protected from environmental EMI / RFI than signals over unshielded cables. [0003] Shielded electrical cables are usually provided with a cable shield formed from a tape wrapped around a conductor assembly. Signal conductors are usually arranged in pairs to carry differential signals. The signal conductor is surrounded by an insulator, and the cable shield is wrapped around the insulator. However, ...
