Definitions

  • the invention relates to a coaxial connector having an inner conductor, an outer conductor and a surge protector with an inductance to ground and a capacitor, wherein the capacitor is connected in series with the inner conductor and having a first capacitor plate which is connected to a first inner conductor of an input of the coaxial connector , and a second capacitor plate, which is connected to a second inner conductor of an output of the coaxial connector, according to the preamble of claim 1.
  • US Pat. No. 6,061,223 discloses a coaxial connector with lightning protection in which a meandering coil connects the inner conductor to the outer conductor. This coil extends radially from the inner conductor out to the outer conductor and short low-frequency currents, such as due to voltages in a lightning strike, to ground short. On the other hand, high-frequency currents are not dissipated through the coil, but pass through the inner conductor in the axial direction.
  • the inner conductor is equipped with a capacitor. This can pass high-frequency currents and blocks low-frequency currents due to residual voltages when dissipating a lightning strike through the coil.
  • a coaxial connector with integrated electrical circuit is known.
  • a PI filter is applied on a circuit board.
  • an axial coil is arranged in a recess of the printed circuit board whose ends are connected to a capacitor connected to ground and applied to the printed circuit board.
  • the invention has for its object to provide a coaxial connector of o.g. To improve the type of manufacture and assembly.
  • the inductance is formed as an axial coil and coaxial with the inner conductor, wherein a first end of the axial coil is connected to the first capacitor plate and a second, the condenser facing away from the end of the axial coil at an axially spaced in the direction of entrance of the coaxial connector connected to the outer conductor.
  • the axial coil on a dielectric base body are applied to the coil windings of a wire of conductive material.
  • the axial coil and the first capacitor plate are integrally formed from a tube closed on one side of conductive material, wherein on the closed side, the first capacitor plate is formed and further wherein the tube between the closed side and an open side in a helical order Having a pipe wall extending around slot which divides the pipe wall into corresponding coil turns to an axial coil.
  • a simpler installation and a cost-effective production is achieved in that the first inner conductor is formed integrally with the first capacitor plate.
  • the first end of the axial coil in the region of an outer peripheral edge of the first capacitor plate is electrically connected thereto.
  • the first preferred embodiment of a coaxial connector according to the invention with overvoltage protection comprises an input 10, an output 12, a 10 connected to the input first inner conductor 14, a second output connected to the inner conductor 12 and an outer conductor 18 e.
  • a capacitor 20 is provided with a first capacitor connected to the first inner conductor 14 and a second capacitor plate 22 connected to the second inner conductor 16 second capacitor plate 24.
  • the overvoltage protection further comprises an inductance which, in the form of a helical coil 26, coaxially surrounds the first inner conductor 14, starting from the first capacitor plate 22 in the direction of the input 10.
  • a first end 28 of the helical coil 26 is electrically connected to the first capacitor plate 22 adjacent to its outer periphery.
  • a second, facing away from the capacitor 20 end 30 of the helix coil 26 is electrically connected to the outer conductor 18.
  • the helical coil 26 is slid onto a tubular dielectric 32 which is held by the first inner conductor 14 and adjusts to a desired impedance.
  • the helical coil is formed so that it does not change its diameter between the first and second ends, but extends substantially in the axial direction.
  • the helix coil forms a choke, so that such currents do not drain via the helix coil to ground, but from the first inner conductor 14 via the capacitor 20 to the second inner conductor 16 and thus transmitted to the output 12.
  • the second preferred embodiment of FIG. 2 works, but here the overvoltage protection helical coil 26 and capacitor 20 is constructed in a mechanically different manner.
  • the first capacitor plate 22 and the helix coil 26 are made in one piece from a tube 34 closed at one end.
  • the first capacitor plate 22 is formed, for example, by twisting off a part of the circumference of the tube 34 at its closed end.
  • a slot also extends helically between the closed end and the open end of the tube 34 and thereby divides a predetermined portion of a tube wall of the tube 34 into adjacent turns, so that the helix coil 26 is formed on the cylindrical tube jacket is.
  • the first inner conductor 14 is screwed, for example, in the first capacitor plate 22, pressed or integrally formed therewith.
  • the inductance in the form of the helix coil is particularly simple, fast, inexpensive and mass-produced. For this purpose, only a corresponding milling / turning of a tube blank is to perform.
