Abstract

In an electronic cable, a shielding tape prevents and mitigates the creation and propagation of micro-fractures and the deleterious effects thereof. In some embodiments, the shielding tape has layers which are oriented in a non-zero transverse relation with respect to each other, or have been treated to have non-zero orientations. Other embodiments include micro-fracture propagation mitigation means, such as perforations, ridges, waffling, and dimpling. In some embodiments, the layers of the shielding tape are bonded to each other with an electrically-conductive elastomeric adhesive. In other embodiments, the shielding tape is wrapped around a cable's dielectric and form an overlap gap, which is filled by an electrically-conductive elastomeric adhesive.

Claims (6)

1. Shielding tape in an electronic cable, the shielding tape comprising:

a first metallic layer having a first orientation along which micro-fractures are predisposed to form;

a second metallic layer having a second orientation along which micro-fractures are predisposed to form; and

the first and second orientations have a non-zero transverse relation with respect to each other.

2. The shielding tape of claim 1 , wherein the first and second orientations in the first and second metallic layers are formed by burnishing the first and second metallic layers.

3. The shielding tape of claim 1 , wherein the first metallic layer is arranged with a non-zero transverse orientation with respect to the second metallic layer.
