  • spring element made of an elastomer consists.
  • Such spring elements are special simple and therefore inexpensive to manufacture. You can for example, consist of vulcanized rubber.
  • the aforementioned embodiment has the disadvantage that that at high temperatures, such as at a lightning strike on the outer conductor of the coaxial cable occur, there is a risk that the spring element is heated so much that it cools down loses its elastic properties or even gets destroyed. There is also a risk that the spring element made of elastomer heats up so much will start to burn For this reason, see other developments of the teaching according to the invention before that the spring element made of electrically conductive Material, preferably made of metal. With these Embodiments is the risk that the spring element warmed too much, decreased, in particular applies to those embodiments in which the Spring element made of metal.
