Embodiment Construction

[0015] Articles having composite shields and methods of making articles having composite shields are provided. Embodiments of the present disclosure, for example, allow for increased shielding of electronic components, allow for increased shielding effectiveness in the high and low frequency ranges, allow for flexibility, for example, compared to concepts that do not include one or more of the features disclosed herein, Allows for lower electrical resistivity, allows for lower manufacturing costs, allows for reduced weight of articles comprising such composite shields rather than alternative shielding mechanisms, allows for fixation heat recoverable without the use of adhesives that adversely increase electrical resistivity materials, allowing other suitable advantages and differences, and combinations of the above.

[0016] figure 1 Illustrated is a method 100 of manufacturing a heat-recovered conductive composite shield 101 formed into a product such as a tube, sheet, sleev...

Abstract

An article and process are described. The article includes a conductive heat- recoverable composite shield or a conductive heat-recovered composite shield (101) formed from a conductive heat-recoverable composite shield (103). The conductive composite shield and / or the conductive heat-recovered composite shield formed from a conductive heat-recoverable composite shield comprises a non-conductive matrix and conductive particles within the non-conductive matrix. The article has a resistivity of less than 0.05 ohm-cm. A process (100) of producing the conductive heat-recovered composite shield includes extruding (102) the conductive heat-recoverable composite shield (103) and heating (104) the conductive heat-recoverable composite shield thereby forming the conductive heat-recovered compositeshield.

Description

technical field [0001] The present invention relates to articles having composite shields and methods of making such articles. More particularly, the present invention relates to heat recoverable and heat recovered composite shields. Background technique [0002] In general, the cable shielding material can be metallic or include ferrite. Metal shields come in the form of braids, tapes, tubes, spirals, braided wire mesh with plastic covers, laminates, plated yarns and fabrics, and many more arrangements. Such shields provide shielding for low frequency applications, but they have several disadvantages. For example, due to low optical coverage, the shielding effectiveness of the braid is reduced in the high frequency range. Metal shields can be heavy and / or require expensive and complicated plating processes. Ferrite beads are used for high-frequency noise suppression, but they are limited by the frequency range allowed by a particular type of ferrite and are not suitable...
