Coaxial cable and method of manufacturing a coaxial cable

Abstract

The invention relates to a coaxial cable (100) comprising an inner conductor (110) and an outer conductor (120) which is arranged radially outside of said inner conductor (110) and which is electrically isolated from said inner conductor (110), wherein at least one stress absorbing element (130) for absorbing mechanical stress is arranged radially between said inner conductor (110) and said outerconductor (120).

Description

technical field [0001] The invention relates to a coaxial cable comprising an inner conductor and an outer conductor arranged radially outside said inner conductor and electrically isolated from said inner conductor. [0002] The invention also relates to a method of manufacturing a coaxial cable. Background technique [0003] Coaxial cables can be used to transmit electrical signals, especially in the radio frequency RF range, for example to supply telecommunication equipment with signals in the frequency range between a few MHz (megahertz) and a few GHz (gigahertz). For this purpose, the inner conductor and the outer conductor comprise or are made of an electrically conductive material such as copper. [0004] Although for RF signals in particular, the penetration depth of the currents associated with RF signals is relatively low due to the skin effect, whereby a correspondingly low material thickness would be required to properly guide the RF within the electrical conduc...

[0004] Although for RF signals in particular, the penetration depth of the currents associated with RF signals is relatively low due to the skin effect, whereby a correspondingly low material thickness would be required to properly guide the RF within the electrical conductors of a conventional cable. current, however the inner and / or outer conductors of conventional coaxial cables typically comprise a relatively large material thickness or wall thickness, respectively, which is, in particular, greater than that required from the standpoint of RF signal transmission, so Requires large and expensive resources such as copper
