- RF radio frequency
- a generic coaxial connector has become known, for example, from US 4,575,694.
- a known RF connector from a bore in the outer conductor material is provided to provide here a switchable termination impedance.
- a coupling element for connecting a signal transmission device to a coaxial main line can be taken as known. It is a capacitive coupling element for connecting a signal transmission device to a coaxial main line. In this case, a coaxial tap using a coaxial segment of the outer conductor is provided.
- the object of the present invention is therefore to provide an improved coaxial RF connector, which allows a compact extraction of low-frequency control signals and / or DC components of a high-frequency useful signal.
- the inventive solution is characterized by its compactness and 'their variable field of application.
- the corresponding separating device is accommodated in the coaxial plug connector itself for separating high-frequency useful signals from low-frequency control signals and / or a remote supply voltage (DC voltage component).

- the contact connector according to the invention now comprises a branch circuit with an RF inner conductor, on which the radio-frequency signals continue to be transmitted, and a LF inner conductor, on which the low-frequency control signals and / or the DC voltage component for the optionally required remote supply voltage is coupled out.
- this is done by a ⁇ / 4 locking pot.
- this locking pot is accommodated in a corresponding bore in the connector outer conductor, whereby a further improvement in the RF signal attenuation is realized.
- the angle should preferably have less than ⁇ 10 °, in particular less than ⁇ 5 ° between the two branch lines.
- the RF signal conductor is preferably continued in the axial extension of the connector inner conductor and the NF inner conductor is arranged as a branch line with radial offset to the RF signal conductor on the output side in the coaxial connector.
- the branch circuit is designed such that the two preferably mutually parallel line branches for the RF and the NF signals both come to rest with radial offset to the plug-side coaxial inner conductor.
- the entire arrangement can be designed such that the preassembled plug connector inner conductor with attached dielectric and the branching arrangement consisting of the RF inner conductor and the NF inner conductor with the associated blocking pot can be inserted and mounted from the plug side into the outer conductor , But the entire arrangement can also be designed and be designed that a corresponding mounting from the opposite side is possible or that the assembly of the connector components takes place on both sides.
- the connector according to the invention is extremely inexpensive to produce, since in contrast to conventional connectors only in the outer conductor an additional hole is necessary.

- a coaxial connector 1 is shown in axial section, a connector outer conductor 3 and connector terminal side (ie, lying left in Figure 1) coaxial thereto in a known manner a connector inner conductor 5 includes, via an insulator, in the shown Embodiment, a disc-shaped dielectric 7 is held in the outer conductor 3 while avoiding an electrical-galvanic contact between the inner and outer conductor.
- the connector inner conductor plug connector side has a socket-shaped extension 5 '.
- a pin-shaped inner conductor connection can also be provided at this point.
- the coaxial connector formed in this way is preferably standardized on its coaxial connection side 8, for example as a 7/16 connector according to EN 122 190.
- the standardized region on the connection side 8 in the axial extension of the plug connector inner conductor 5 then merges into an RF inner conductor 9, specifically via a tapered intermediate section 5 ".
- transitions from connector inner conductor 5 to RF inner conductor 9 and from bore 12a to bore 12c need not be continuous as in the embodiment. There are also sudden changes in diameter between the cut possible.
- the RF inner conductor 9 terminates in front of the front-side outer conductor end 10, where in the radial direction extending a coaxial RF cable (high-frequency signals) coaxial connection cable 13 is connected via a radial bore 15 in the connector outer conductor 3.
- the coaxial connection cable 13 is correspondingly stepped stripped at its terminal end, the associated inner conductor 13 a passed through a preferably groove-like outbreak in the RF inner conductor 9 and soldered to it.
- the dielectric 13c surrounding the inner conductor 13a insulates the inner conductor from the outer conductor of the connector and is inserted into the radial bore 15 for this purpose.
- the stepped outer conductor 13b is the front side of the sleeve-shaped connection portion 17, which is part of the connector outer conductor 3, the front side and / or electrically contacted at the peripheral portion. 13d, the outer insulation of the coaxial connection cable 13 is shown.
- a coaxial cable is now connected to the coaxial connector of this kind on the connection side, via which not only RF signals (ie high-frequency useful signals) but also LF signals (for example low-frequency control signals and / or also a remote supply voltage or DC voltage) are transmitted by means of the coaxial connector according to the invention via.
- RF signals ie high-frequency useful signals
- LF signals for example low-frequency control signals and / or also a remote supply voltage or DC voltage
- a further bore 21 is parallel to the exit-side axial bore 12c (with a smaller diameter than the inlet-side axial bore 12a) then introduced in the material of the connector outer conductor 3, in which the mentioned Auskoppelzweig 23 is housed, the NF-inner conductor 27, inner dielectric 35, blocking pot 31 and outer dielectric 37 is made.
- the LF inner conductor is subdivided into a radial section 27a and an axial section 27b, which runs parallel to the RF inner conductor 9 in the exemplary embodiment shown.
- a locking pot 31 On the axial portion 27b of the NF inner conductor 27, a locking pot 31 is provided.
- the NF inner conductor 27 of the Auskoppelzweiges 23 is soldered to the bottom 31 b of the locking pot 31, and at the solder joint 34.
- the corresponding ratios are reproduced in an enlarged detail display ⁇ tion in Figure 2. Is the length of the inner bore of the locking pot
- ⁇ r is the corresponding dielectric constant of the inner dielectric 35 used and ⁇ is the mean wavelength of the frequency range to be transmitted in the RF branch, preferably the average wavelength of this frequency range, the short circuit formed thereby becomes inside the plastic or generally with a dielectric 35th filled locking pot to the open end of the locking pot transformed into an open circuit ( ⁇ / 4 electrical length).
- This open circuit on the open side 31c of the blocking pot 31 is provided very close to the branching point 24 of the decoupling branch 23 and thereby causes the RF signal not to be fed into the output branch 23 but into the HF branch and thus via the HF branch.
- Inner conductor 9 flows.
- a dielectric 35 inner dielectric 35
- the dielectric 37 outer dielectric 37
- a dielectric of a different material even of air or the like, can in principle also be used.
- Lock pot and the surrounding the locking pot adjacent Wall 21a of the bore 21 formed.
- This distance space between the outer or peripheral surface of the locking pot 31 and the adjacent inner wall 21a of the bore 21, in which the locking pot is seated, is filled in the embodiment 5 shown, for example, by means of an insulator or dielectric 37 in order to reliably avoid an electrical-galvanic connection ,
- the NF inner conductor therefore protrudes axially in the axial extension at the connection end 10 of the connector housing thus formed.
- the connector inner conductor 5 integrally connected to the RF inner conductor 9 can be plugged onto a disc-shaped dielectric 7 as shown in FIG. 3a. Subsequently, the radial LF inner conductor section 27a of the premonstrative
- the arrangement may be such that the unit prepared in this way and shown perspectively in FIG. 3b, including the decoupling branch 23, is inserted from the coaxial terminal side 8 into the connector outer conductor housing 3. Subsequently, only the mentioned end of the radially supplied connection cable 13 must be inserted at the radial connection section 17 and the associated inner conductor and outer conductor sections connected accordingly.
- the terminal-side outer conductor opening 3a can then be closed by an end cap 41.
- a corresponding coaxial connector 1 without the aforementioned radially supplied connecting cable 17 is reproduced in the figure 4a again in axial section and in Figures 4b and 4c in perspective view.
- a coaxial connector explained in accordance with FIG. 1 is connected to an electronics housing 43, wherein only the decoupled LF signals and a possibly provided DC voltage signal (remote supply voltage) are fed via the LF inner conductor 27 into the electronics housing, namely via an electronics housing 43 provided opening or bore 43 a.
- the inner conductor projection can be sized so large that it extends to a housed in the electronics housing 43 printed circuit board 45 and, where appropriate, this still penetrated in a bore 45a and can be soldered there.
- the HF signals are forwarded via the HF connection cable 13.
- the RF inner conductor 9 is also designed to be axially elongated and projects beyond the terminal end 10 of the plug connector outer conductor or outer conductor housing 3 and, in this case, likewise leads into the electronics housing 43 via a further bore 43b, if necessary into a second chamber 43 ", which is separated from a first chamber 43 'by a shielded wall 44, into which the LF inner conductor 27 leads in. If the housing 43 is produced by casting, the outer conductor can be produced very cost-effectively in this embodiment variant 3 fully or at least partially in the same manufacturing process.
- connection end 10 is also different in this embodiment. Also different in this embodiment is the embodiment of the connector outer conductor 3 at its connection end 10, which is provided here with a connection flange 3b.
- connection flange 3b which is designed square in the embodiment shown and in the corners has four holes, about which screws can be screwed into the electrical housing (for Be ⁇ fastening of the coaxial connector).
- FIGS. 6b and 6c also show that in addition to the central bore 21 in the axial offset there is provided not only for the decoupling branch a further axial bore 21a but also a second bore 21b which is also parallel. This makes it possible, for example, to accommodate a second branch line, which is constructed like the first branch line 23 and connected to the RF inner conductor 9. is coupled. If a plurality of branch lines are provided, the associated blocking pots may also have different lengths to block different frequency ranges. Therefore, in principle even more than one locking pot or even more than two locking pots can be arranged.
- the blocking pots or the branch line 27 do not always have to be arranged parallel to the HF inner conductor. Both lines can also diverge or at least slightly diverge. However, a diverging angle should, if possible, be less than 10 °, particularly preferably less than 9 °.
- the construction could conversely also be designed so that the LF inner conductor 27 extends in the axial extension of the connector inner conductor 5 and the connector inner conductor 5 thus virtually merges into the LF inner conductor 27.
- the HF internal conductor 9 branch off to a first radial portion of NF-inner conductor 27, and then pass into a preferably parallel portion. This would virtually lead to an exchange of the two branches shown in FIG.
- FIG. 7 differs from that according to FIG. 1 in that the decoupling device 23 has a larger outer diameter and that the blocking pot, viewed from the central axial line 51, lies further outward, ie ends radially further outwards, so that the bore 21a does not is completely aligned with the connection-side bore 12a, but forms a stepped shoulder 3d in the central region.
- This structure may be necessary if the decoupling unit must have a large characteristic impedance, which is determined by the ratio of the inner diameter of the locking cup to the outer diameter of the LF inner conductor, in order to achieve a high decoupling between HF and LF signals.
- the outer conductor inner diameter and the inner conductor diameter decrease from the connector side to the connection side, preferably with constant characteristic impedance.
- the characteristic impedance does not necessarily have stay.
- the outer conductor inner diameter and the réelleleiter- fürr ⁇ esser remain the same.
- the invention can be implemented such that, for example, both diameters or at least one of them increase from the connector side to the connection side.
- the characteristic impedance does not necessarily have to remain the same over the entire length, since, for example, in intentional deviation from a desired characteristic impedance, other characteristic impedance values may also be important, for example. to be compensated from a standard range or caused by solder joints characteristic impedance deviations.
