Definitions

  • the invention relates to a coupling element for connecting a signal transmission device to a coaxial main line with a connection part fastened to it in the course of the main line, with which a connection suitable for signal transmission can be established.
  • a coupling of signal transmission devices to a main line in the form of a coaxial cable is often necessary in the communications and data technology, the main lines are usually permanently installed and a complete interruption of the main line to connect special branch points often leads to interference in the signal transmission.
  • bus systems local networks
  • a large number of transmitting / receiving devices are connected to a common, often permanently installed transmission line (bus).
  • a coupling element is already known (Design Guide to AMP-Coaxial Taps, AMP Incorporated Harrisburg, DP 5525, Rev A, 1982, pages 1 to 9), in which one or more contacting pins pass through the insulating jacket, the outer conductor and the dielectric of the coaxial cable be pressed. This or these contacting pins establish the connection between the inner conductor of the coaxial cable and a connection of the signal transmission device; the outer conductor of the coaxial cable is also contacted with a connection of the signal transmission device by means of cutting, soldering or clamping contacts.
  • the contact security depends on the care taken when making contact and in particular on the contact pressure.
  • the invention has for its object to provide a coupling element for connecting a signal transmission device to a coaxial main line, in which the influence of the coupling element and the coupled devices on the main line are kept as low as possible.
  • a cylindrical segment of the outer conductor of the coaxial main line is formed by two spaced-apart interruption points of the outer conductor in a coupling element of the type specified above, the segment is electrically insulated from it by a conductive cylindrical element of the connecting part, and each with one End connected to the outer conductor of the main line at each interruption point, a first capacitance being formed between the segment and the inner conductor of the main line and a second capacitance between the segment and the cylindrical element, and the one conductor of the connection of the signal transmission supply device on the segment and the other conductor on the cylindrical element can be connected via the connecting part.
  • the coupling element according to the invention is also mechanically extremely stable, since it can be securely fastened to the conductive jacket (outer conductor) of the main line with a high degree of contact security and mechanical access to the inner conductor is not necessary.
  • the electrical transmission behavior it is advantageous that the reflections and reactions from the coupled device can be kept extremely low, since the conductor configuration and the dielectric of the main line are largely preserved.
  • the risk of a short circuit, which cannot be excluded in the case of mechanical contacting is completely avoided.
  • the coupling element is also possible to design the coupling element as a separate component, so that this type of coupling can also be advantageously used with a main line, the interruption of which does not present any difficulties or which is already disconnected.
  • FIG. 1 shows a coaxial main line 1 with an inner conductor 2, a dielectric 3 and a cylindrical outer conductor 4.
  • the entire main line 1 is enclosed by an insulating plastic jacket 5.
  • the outer conductor 4 is removed, so that a cylindrical segment 8 is formed, which is electrically insulated from the rest of the outer conductor 4.
  • the cylindrical segment 8 is completely enclosed by a conductive cylindrical element 9, which is insulated from the segment 8 by a dielectric intermediate layer 10 and is also electrically connected to the outer conductor 4 at points 11 and 12 (e.g. by soldering or clamping) .
  • the axial dimensions of the interruption points 6 and 7 are designated by b, the dimensions of the overlap or contacting points between the cylindrical element 9 and the outer conductor 4 are identified by a and the entire length of the cylindrical element 9 is 1.
  • the cylindrical element 9 can For example, be composed of two half-shells with an axial separation surface.
  • the cylindrical element 9 has a recess 13, through which a contact pin 14 is guided, which is connected to the cylindrical segment 8 in an electrically conductive manner via a connecting element 15.
  • the contacting pin 14 represents the inner conductor of a coaxial screw connection, to which a screw socket 16 belongs, which is held in an electrically conductive manner on the cylindrical element 9.
  • a transmission / reception device can be coupled as a signal transmission device with a coaxial connection.
  • FIG. 2 shows in simplified form the conductive coatings that are formed by the coupling element.
  • the outer conductor 4 together with the cylindrical element 9 and the cylindrical segment 8 form a tubular capacitor, as well as the cylindrical segment 8 together with the inner conductor 2.
  • the capacitive decoupling of the signal to the coupled device takes place via the pads, including the contacting pin 14.
  • the electrical equivalent circuit diagram according to FIG. 3 shows a first capacitance C 0 , which is formed between the inner conductor 2 and the segment 8 as a tubular condenser, and also a second capacitance C 1 , which lies between the cylindrical element 9 and the segment 8 as a T circuit , and half the wave resistance the main line 1 on one side and a parasitic capacitance C T with an input resistance R of the downstream device on the other side of the T circuit.
  • This circuit has a high-pass character in the receiving direction and a band-pass character in the sending direction. The cut-off frequencies and attenuations depend on the dimensions of the coupling element, the characteristic impedance Z and the electrical properties of the coupled signal transmission device (for example C T and R T ).
  • the capacitance values C 0 and C 1 are calculated as follows: 0 where ⁇ the permittivity of vacuum (0.8855 10 -13 F / cm), and ⁇ r0 D ielektrizticianskonstante of the dielectric 3 and ⁇ r1 represent the dielectric constant of the interlayer insulating layer 10th
  • the reflection behavior can be described approximately by changing the wave resistance over the length 1;
  • the resulting echo pulses for example in the case of square-wave signals, have a duration which corresponds to twice the transit time via the coupling (approx. 2 x 5 ns / m).
  • the amplitude of these pulses is determined by the ratio r 0 / r 1 .
  • Parasitic capacitances C T in the peripheral transceiver increase the constant portion of the input / output coupling attenuation, but do not have a negative effect on the reflection behavior with this type of coupling.
  • a short circuit in the peripheral device does not cause any additional reflections here, as a result of which the transmission on the main line (bus) is not impaired.
