TWIN AXIAL CABLE STRUCTURES FOR TRANSMITTING SIGNALS

摘要

A twin axial cable structure is provided for transmitting signals that makes use of insulative materials that are not easily extruded, such as expanded polyethylene (ePE) and expanded polytetrafluoroethylene (ePTFE). The cable structure includes an insulative body portion having a pair of open channels defined through an outer longitudinal surface of the insulative body portion, in which are disposed a pair of conductive wires. A conductive sheet is disposed on the insulative body portion, and a grounding element is placed in contact with the conductive sheet, such as by applying planar conductive sheets and grounding elements and/or ground wires to the insulative body portion. Corresponding methods and apparatuses for manufacturing the same are also provided. The cable structures, methods, and apparatuses described herein can produce a cable structure for transmitting multiple differential signals within the same structure, with minimal negative effects on other, neighboring transmissions.

1. A cable structure for transmitting a differential signal comprising:
an insulative body portion defining a pair of open channels, wherein the channels are parallel to each other and extend a length of the insulative body portion, wherein each channel is defined through an outer longitudinal surface of the insulative body portion and extends through opposite ends of the insulative body portion; a pair of conductive wires disposed within the pair of open channels, wherein the pair of conductive wires is configured to collectively transmit a differential signal; a conductive sheet disposed on the insulative body portion and configured to shield the pair of conductive wires; and a grounding element in contact with the conductive sheet and configured to conduct electric current away from the conductive sheet.
