Definitions

  • the present invention relates to an EMP arrester in a coaxial line of a housing placed in the outer conductor and one with the inner conductor the coaxially electrically connected ⁇ / 4 line at their The end of an arrester is contacted with the housing in accordance with the definition of the claims.
  • Swiss patent application 158/97 provides for a gas discharge - Surge arrester which is between the outer conductor of the coaxial line and the ⁇ / 2 line is contacted to derive interference currents and interference voltages or reflect.
  • This ⁇ / 2 line with its pot circles and the in series switched gas discharge surge arrester acts as a frequency selective Filters for multiple frequency bands and allows the simultaneous transmission of AC / DC supply voltages.
  • the EMP arrester according to an embodiment of claim 1 shows an arrester that is between the housing and an electrically extended ⁇ / 4 line is used interchangeably, wherein a capacitance is connected in parallel to the arrester, which also carries the line for HF connects the housing and together with the ⁇ / 4 line a parallel resonant circuit forms.
  • Gas discharge surge arresters are suitable as surge arresters, Varistors or different types of diodes.
  • This circuit enables the transmission of AC / DC supply voltage and is for suitable for the simultaneous transmission of RF frequency bands with high power, without generating intermodulation products or without Use of a gas discharge surge arrester whose extinguishing behavior negatively changes. Furthermore, this switching arrangement enables the transmission of large ones HF power, this in broad frequency bands, with very high, with upwards in principle unlimited frequencies and with the smallest static response voltage the surge arrester. With this invention, terminals with AC / DC dine and at the same time effectively protect against harmful electrical surges.
  • the sectional view according to FIG. 2 or 6, for example, as a plug-in coupling designed EMP arrester consists of an outer conductor 10, which as a cylindrical Housing with connectors 11 and 12 arranged on both sides for screw connections or has plug connections of coaxial conductors.
  • the connector is 11 left in the drawing as a connection to the unprotected area, for example to an antenna, thought and the connector 12, right in the drawing is supposed to be the protected one Connect to an electronic device.
  • this EMP arrester on a screw connection or to be attached to a housing bushing as an earth connection. Is to a screw connection 18 or a flange 13 on the outer conductor 10 is present together with a washer 17 or the like.
  • An outer hollow cylinder is screwed into a middle part 106 of the outer conductor 10 or put on.
  • This outer hollow cylinder 20 is with a screwed end cover 21 provided.
  • An arrester 28 is inserted into the end cover 21.
  • the arrester 28 can as a gas discharge surge arrester (see Figures 1 and 2), or as a Varistor (see FIG. 3), or also as a diode, for example as a transzorb diode, zener diode, Suppressor diode, protection diode, etc. (see Figure 4) can be designed.
  • the arrester 28 is interchangeable and can be opened by opening the cover 21 can be replaced quickly and easily.
  • the length of line 24 is electrical extended ⁇ / 4 wavelength of the frequency band to be transmitted tuned.
  • the Diverter 28 is contacted between a line 24 and the end cover 21.
  • the disk 40 with the concentrated capacitance 41 is arranged parallel to the arrester 28.
  • the line 24 between the inner conductor 30 and the arrester 28 acts by the capacitance of the capacitance 41 as the ⁇ / 4 short-circuit line of the transmission Frequency band.
  • the electrical length of line 24 can be achieved by attaching dielectrics 25 Shorten geometrically in the area of the line 24. For this reason they are hollow cylinders 20 and conductor 24 in Figures 2 and 6 shown interrupted. Also lets the length of line 24 is concentrated by attaching one or more Capacities or reactances, which are, for example, by one or more End disks 26, cup or cylinder capacities are formed, shorten geometrically. These measures are optional, but they have many advantages because they enable, for example, a small installation dimension, thereby simple assembly, etc..
  • the bandwidth of the frequency band to be transmitted can be subdivided of the inner conductor 30 into different line sections 31, 32, 33, 34, with attribution corresponding wave impedances.
  • An exemplary arrangement such line sections 31, 32, 33, 34 is shown in Figures 5 and 6.
  • the Bandwidth of the frequency band to be transmitted via bandpass transformations set to up to an octave.
  • the concentrated capacitance 41 and the arrester 28 are connected in parallel. With the Line 24, the dielectric 25 attached in the area of line 24, one or a plurality of end disks 26 of the line 24 and the concentrated capacity 41 the arrester 28 decouple to such an extent that the transmitted HF frequency band No voltage maxima occur at the front. That way For example, a gas discharge surge arrester cannot pre-ionize.
  • the dielectric 25 attached in the area of the line 24, one or more end disks 26 of the line 24, the line sections 31, 32, 33, 34 and their impedances becomes the bandwidth as well as the frequency range of the transmitted signal determined.
  • This allows bandwidths up to an octave realize and at the same time transfer AC / DC supply voltages and protect against harmful Protect interferers, so that all kinds of end devices against EMP effects can be protected.
  • For example. become frequency bands between 100 MHz and 30 GHz transmitted.
  • the level of the transmissible frequencies is determined by the inventive Switching is not limited per se, the connector sizes are limiting. It is quite possible to use frequencies when using other connector sizes to be transmitted far above 30 GHz.
