A flexible tube or snare is often used to surround fine wire leads, such as those extending from the transducer of a disk drive actuator assembly, to afford protection against tangling or abrasion. Although this provides mechanical protection, there is also a need to obtain noise reduction through protection against electromagnetic conditions. To protect against electrical noise as well as mechanical abrasion, the snare illustrated in the figure shows a flexible tube 3 surrounding the electrical leads 4 with a conductive layer 5 surrounding the flexible tube. The conductive layer 5 is electrically connected to a grounding lead 6. The conductive layer may be a braided wire tube of conventional design that closely surrounds the flexible tube.
