Embodiment Construction

[0022] Embodiments described herein include cable assemblies and cable harnesses configured to suppress electromagnetic interference (EMI). The cable assembly includes an assembly housing that holds one or more electrical connectors. The electrical connector is configured to transmit power and / or data signals. The component housing includes an interior chamber in which at least a portion of the electrical connector is disposed. The assembly housing has one or more loading channels each receiving a portion of the cable harness. A cable harness consists of insulated wires and a shield surrounding the insulated wires. The cable harness also includes a discrete ferrule that surrounds the covered segment of the cable harness and engages the assembly housing. A harness housing seam may be defined by the cable harness and the component housing. Various embodiments are configured to reduce or suppress EMI leakage through harness housing seams.

[0023] The insulated wires are ter...

Abstract

Cable assembly (100) includes an assembly housing (104) having an interior cavity (470) and a loading passage (126) that provides access to the interior cavity. The assembly housing has an inner housing surface (474) that defines the loading passage (126). The cable assembly (100) also includes a cable harness (125) having insulated wires (244) and a conductive shielding layer (224). The insulatedwires (244) extend through a cable passage (242) defined by the shielding layer (224). The cable harness also includes a discrete ferrule positioned within the cable passage at an end of the cable passage. The discrete ferrule has an outer ferrule surface (478) that is surrounded by the shielding layer. The inner housing surface (474) and the outer ferrule surface (478) interface each other alonga harness-housing seam (490). The harness-housing seam (490) includes a projection and a recess that receives the projection. The shielding layer is stretched by the projection within the harness-housing seam (490) and electrically grounds the cable harness to the assembly housing.

Description

technical field [0001] The subject matter herein relates generally to cable assemblies, including cable harnesses for interconnecting communication systems or devices. Background technique [0002] Communication systems, such as routers, servers, switches, Redundant Array of Inexpensive Disks (RAID), Uninterruptible Power Supplies (UPS), Host Bus Adapters (HBAs), supercomputers, etc., can be large and complex Multiple components interconnected by a cable assembly. For example, a cable backplane (or cable midplane) system includes several daughter card assemblies interconnected with each other through cable assemblies. Daughter card assemblies of such systems may also be interconnected with remote components or devices through different types of cable assemblies. Examples of such circuit assemblies include pluggable input / output (I / O) cable assemblies. [0003] A cable assembly may include a cable harness (or multi-conductor cable), one or more electrical connectors, and a...
