Abstract:
An electrical signal transmission device including a core and an outer conductor separated by a dielectric wherein, to eliminate external radiated interference, for which said device acts as a receiving antenna for said external radiated interference, said outer conductor features discontinuities forming impedance discontinuities, a set of discontinuities being chosen to prevent propagation towards said core of external interference waves in a particular range of frequencies,wherein said outer conductor is subdivided in an axial direction into alternating sections, at least one first section of said alternations having an outer conductor covering a first amount of the outer periphery of said dielectric and at least one second section of said alternations having an outer conductor covering a second amount of the outer periphery of said dielectric, wherein one of said first section and said second section having at least one aperture and where said first and second sections are electrically connected.
