Definitions

  • the present invention relates to a coaxial cable connector for connecting to a coaxial cable.
  • coaxial cables as e.g. described in the US 2004/123999 may be employed.
  • a coaxial cable comprises an inner conductor, an outer conductor and a dielectric material disposed there between.
  • the outer conductor of the coaxial cable may be formed from copper which is, however, expensive and has a high weight.
  • the outer conductor may be formed from aluminum which may further be coated with a thin layer.
  • aluminum is difficult to form and to handle.
  • the corrosion resistance of aluminum is less than the corrosion resistance of copper.
  • coaxial cable connectors may be employed.
  • a coaxial cable connector may comprise specific connector parts connected to an inner conductor and an outer conductor of a coaxial cable, respectively.
  • corrosion may occur.
  • the outer conductor may be coated by e.g. a jacket, further corrosion may occur due to possible water ingress between the outer conductor and the jacket.
  • problems of installing the connector may occur due to the softness of aluminum.
  • the invention is based on the finding that the corrosion resistance may be improved when at least one connecting element of a coaxial cable connector is or comprises an alloy of copper, tin and zinc.
  • a connector may be used in particular for connecting to coaxial cables having an outer conductor formed from aluminum since the inventive alloy significantly increases the corrosion resistance.
  • the improvement of corrosion resistance associated with using the inventive alloy of copper, tin and zinc is due to the fact that the electrochemical voltage between e.g. a connector and an outer conductor of a coaxial cable is reduced.
  • the coaxial cable may comprise an inner conductor covered with a dielectric coating, a heat shrink tube disposed around the dielectric coating and an outer conductor made of e.g. aluminum or of the inventive alloy of copper, tin and zinc.
  • at least one connector having e.g. an outer layer for connecting to the outer conductor, the outer layer comprising the alloy of copper, tin and zinc, may be soldered to the outer conductor of the coaxial cable, wherein at least one sealing ring between the outer conductor and the connector may be provided.
  • At least one further sealing ring may be provided between the outer conductor and the heat shrink tube coating the dielectric material and/or the outer conductor.
  • the invention relates according to an aspect to a coaxial cable connector for connecting to a coaxial cable with an inner conductor and an outer conductor.
  • the connector comprises a first connecting element for connecting to the outer conductor and a second connecting element for connecting to the inner conductor, the first connecting element and/or the second connecting element comprising an alloy of copper, tin and zinc.
  • the connector comprises according to an embodiment a sealing ring arranged between the first connecting element and the second connecting element. Furthermore, the connector may comprise a further sealing ring surrounding the first connecting element.
  • the first connecting element and/or the second connecting element may according to an embodiment further comprise brass.
  • the invention relates according to another aspect to a coaxial cable assembly with a coaxial cable with an outer conductor and an inner conductor and the inventive coaxial cable connector, wherein the first connecting element is connectable, e.g. by soldering, to the outer conductor and the second connecting element is connectable, e.g. by soldering, to the inner conductor.
  • the coaxial cable assembly comprises according to a further embodiment a sealing ring disposed between the outer conductor and the coaxial cable connector.
  • the coaxial cable may comprise a heat shrink tube or a molded plastic sleeve coating the outer conductor. Furthermore, the coaxial cable assembly may further comprise a further sealing ring disposed between the outer conductor and the heat shrink tube.
  • the inner conductor or the outer conductor comprise or consist of aluminum or an alloy of copper, tin and zinc and may additionally comprise brass.
  • the invention relates according to a further aspect to a method for making a coaxial cable connector for connecting to a coaxial cable with an inner conductor and an outer conductor.
  • the method comprises forming a first connecting element for connecting to the outer conductor, the first connecting element comprising an alloy of copper, tin and zinc, and forming a second connecting element for connecting to the inner conductor, the second connecting element comprising copper, aluminum or an alloy of copper, tin and zinc.
  • the method comprises forming a coaxial cable with an outer conductor and an inner conductor, forming the coaxial cable connector, soldering the outer conductor to the first connecting element and soldering the inner conductor to the second connecting element.
  • the invention further relates to a coaxial cable comprising an inner conductor, a dielectric material coating the inner conductor, an outer conductor which may be corrugated and a heat shrink tube coating the outer conductor.
  • the coaxial cable assembly shown in Fig. 1 comprises a coaxial cable with an inner conductor 101 which is coated by a dielectric material 103.

  • the coaxial cable connector further comprises a second connecting element 111 for connecting to the inner conductor 101.
  • the first and the second connecting elements 109 and 111 may have e.g. a rotation symmetric form for accommodating the respective conductor of the coaxial cable.
  • the first connecting element 109 has an overlap section 113 which, when assembled, overlaps with at least a part of the outer conductor 105.
  • the corresponding overlap section of the outer conductor 105 is free of the coating 107.
  • the second connecting element 111 comprises an overlap section 115 for overlapping with at least a part of the inner conductor 101.
