Definitions
- the invention relates to a separating member for connecting two coaxial cables terminated with coaxial connectors with electrical isolation of the inner conductor and the cable metal sheaths, the pot-like, electrically conductive outer sleeve, an electrically conductive inner sleeve arranged concentrically therewith, a first end flange, a hollow cylindrical outer separating capacitor, an insulating washer and has an internal separation capacitor.
- Such a separator is used, for example, to connect a coaxial feed line of a broadband cable network to a coaxial house connection line.
- the broadband cable network used to transmit messages from a central office has a frequency range that extends up to 400 MHz. If return channels are still provided, the lower band limit is around 5 MHz.
- an AC supply voltage is also applied to the coaxial feed line in addition to the HF messages in order to be able to supply amplifiers in the course of the feed line.
- Branch cables lead to the feed line and lead to the message receivers. It is necessary to connect the inner conductors and the metal cable sheaths of the feed line and the house connection cable to each other with high frequency as low as possible.
- a separator of this type is known from GB-A-13 28 604.
- a coaxial cable is firmly connected to the isolating element and the external and internal isolating capacitors are mechanically heavily loaded as load-bearing components.
- sufficient RF shielding can only be achieved with a separate shielding housing in which the isolating element is inserted.
- the structure of the separator is also complicated.
- US-A-39 80 976 shows a separator in which the inner conductor and the outer conductor are galvanically separated by means of inner and outer separating capacitors.
- these isolating capacitors are connected to them in an electrically conductive manner solely by means of the contact forces transmitted via the divided inner conductor or the divided outer conductor. This contact is not clear, especially for high frequencies, and the RF shielding is not complete in the area of the external isolating capacitor.
- FR-A-13 55 646 shows a coaxial connector which is firmly connected to the end of a coaxial cable.
- the inner conductor and the cable jacket of the coaxial cable are connected to the inner and outer sleeves of the coaxial connector via isolating capacitors, all parts being embedded in an insulating part.
- the coaxial cable is always firmly connected.
- the coaxial structure is also maintained in the area of the isolating element and the isolating element is completely shielded in terms of HF.
- a sufficiently large capacitance can be achieved with the hollow cylindrical external separating capacitors, which guarantees a low-resistance transition for the HF currents.
- the inner separating capacitor connecting the inner conductors is held centrally in the middle of the inner sleeve, so that the coaxial structure of the separating member is not significantly affected thereby either.
- the insulating washers take over the electrical isolation of the outer sleeve from the inner sleeve.
- the contact mats thereby ensure a large-area connection of the coatings of the hollow cylindrical outer separating capacitors with the outer sleeve and the inner sleeve, that the contact mats consist of flexible tape, from which a plurality of contact springs are punched and bent and that the contact mats over the entire circumference of the outer sleeve and Extend inner sleeve so as not to deteriorate the coaxial structure.
- the clear galvanic separation of the outer sleeve from the inner sleeve is obtained in one embodiment in that the insulating washer between the bottom the outer sleeve and the facing end of the inner sleeve has an outer diameter corresponding to the inner diameter of the outer sleeve and an inner diameter corresponding to the inner diameter of the inner sleeve, and that the insulating washer between the end flange of the inner sleeve and the facing end face of the outer sleeve has an outer diameter corresponding to the outer diameter of the outer sleeve and one of the Has outer diameter of the inner sleeve corresponding inner diameter.
- a further embodiment provides that the insulating disk projects with a section reduced to the inner diameter of the outer sleeve into the chamber formed between the outer sleeve and the inner sleeve.
- the outer diameter of the end flange of the inner sleeve is smaller than the outer diameter, but larger than the inner diameter of the outer sleeve, and that that of the outer sleeve is turned away Outside of the insulating washer has a receptacle for flush insertion of the end flange.
- the design is such that the carrier plate has a width that is smaller than the inner diameter of the inner sleeve and that the length of the carrier plate and thus the distance between the the first coaxial connector and the socket part is matched to the axial dimension of the outer sleeve and the inner sleeve and thus the distance to the second coaxial connector so that when the coaxial connectors are screwed in, the inner contact of the second coaxial connector is inserted as a plug pin into the socket part connected to the carrier plate.
- the carrier plate can then be freely rotated in the inner sleeve and when the second coaxial connector is screwed into the thread receptacle in the bottom of the outer sleeve, the plug connection between the inner contact of the second coaxial connector and the socket part fixed on the carrier plate is automatically established.
- This plug connection allows the required mutual rotatability of the two coaxial plug connectors, so that it does not really matter which of the two coaxial plug connectors is screwed in first. It is only necessary to ensure that the first coaxial connector forms a sufficiently rigid unit with the carrier plate and the socket part.
- the carrier plate carries conductor tracks separated by slots at both ends and in that the internal contact of the first coaxial connector and a contact pin of the socket part are in each case soldered to these conductor tracks together with one of the connections of the disk isolating capacitor.
- an embodiment has proven to be expedient, which is characterized in that the carrier plate has a breakthrough into which the internal separation capacitor is inserted and held upright in it.
- both coaxial connectors are designed as coaxial sockets, the inner contacts of which end as socket parts and the outer sleeves of which are provided with further external threads for coaxial connectors of the coaxial cables provided with union nuts, in order to be able to completely shield and secure these plug connections between the coaxial cables and the isolating element .
- the pot-like outer sleeve 10 with the bottom 11 and the inner sleeve 13 with the end flange 14 form a hollow cylindrical, shielded chamber for receiving external separating capacitors 20, which are correspondingly hollow-cylindrical and are provided with outer coverings 21 and inner coverings 22.
- the annular insulating washers 16 and 54 are used.
- the insulating disk 16 separates the bottom 11 of the outer sleeve 10 from the facing end face of the inner sleeve 13.
- the outer diameter of the insulating disk 16 corresponds to the inner diameter of the outer sleeve 10
- the inner diameter of the bore 17 corresponds to the inner diameter of the inner sleeve 13.
- the insulating disk 54 has an outer diameter, which corresponds to the outer diameter of the outer sleeve 10.
- the insulating disk 54 On the inner side facing the outer sleeve 10, the insulating disk 54 carries a section reduced to the inner diameter of the outer sleeve, which protrudes into the chamber between the outer sleeve 10 and the inner sleeve 13, since the inner diameter of the insulating disk 54 corresponds to the outer diameter of the inner sleeve 13. This section holds the external separation capacitors 20 axially immovable in the chamber.
- the outer layers 21 of the outer separating capacitors 20 are electrically conductively connected via the contact mat 19 to the inner wall of the outer sleeve 10 and the inner layers 22 of the outer separating capacitors 20 via the contact mat 18 to the outer wall of the inner sleeve 13.
- the contact mats 18 and 19 are made of flexible tape and provided with many punched-out and bent-out contact springs in order to always obtain a large-area connection.
- the contact mats 18 and 19 each extend over the entire circumference of the outer sleeve 10 and the inner sleeve 13.
- the insulating washer 54 carries on the outside facing away from the outer sleeve 10, the receptacle 56 for the end flange 14 of the inner sleeve 13, in order thereby the creepage distance between the outer sleeve 10 and to enlarge the end flange 14 of the inner sleeve 13.
- the outer diameter of the end flange 14 is smaller than the outer diameter of the outer sleeve 10, but larger than the inner diameter of the outer sleeve 10 in order not to deteriorate the shielding of the chamber at this point.
- the bottom 11 of the outer sleeve 10 has the central thread receptacle 12, while the end of the inner sleeve 13 has the internal thread 15 in the region of the end flange 14.
- the first coaxial connector 29 with the external thread 32 of its outer sleeve 35 is screwed into this internal thread 15 of the inner sleeve 13 until the collar 36 stops.
- the inner contact 31 in the insulating part 34 terminates in the socket part 30, so that the first coaxial connector 29 is designed as a coaxial socket.
- the coaxial connector on the coaxial cable is then designed as a coaxial connector.
- the reversed training is also possible.
- the inner contact 31 then runs out into a plug pin.
- the outer sleeve 35 of the first coaxial connector 29 has a further external thread 33, so that a coaxial connector with a union nut can be used, with which the connector can be secured.
- the inner contact 31 of the first coaxial connector 29 is connected to the carrier plate 37, which carries the two conductor tracks 38 and 39 separated from one another by a slot at the facing end. As the solder joint 49 shows, the inner contact 31 is connected to these conductor tracks 38 and 39, and to the connection 42 of the inner separating capacitor 41, which is designed as a disk capacitor.
- This internal separation capacitor 41 stands upright in the opening 40 of the carrier plate 37 so that it is held centrally.
- the other terminal 43 of the internal separating capacitor 41 is soldered together with the contact pin 47 of the socket part 46 to the conductor tracks 44 and 45 separated by a slot at the other end of the carrier plate 37, as the soldering point 50 shows.
- the protruding socket part 46 carries a spring 48 which keeps the slotted socket parts 46 always under tension in order to obtain clear contact with the internal contact 23 of the second coaxial connector 21, which with the external thread 24 of its outer sleeve 27 up to the stop of the collar 28 in the thread receptacle 12 is screwed into the bottom 11 of the outer sleeve 10.
- the inner contact 23 is inserted more and more into the socket part 46 and a plug connection is made.
- the inner contact 23 of the second coaxial connector 21 defined in the insulating part 26 also runs out into a socket part 22, so that a coaxial socket is formed again.
- the attached coaxial connector is secured via the further external thread 25 of the outer sleeve 27.
- the second coaxial connector can also be designed as a coaxial connector. Then only the inner contact 23 and the outer sleeve 27 change.
- solder joints 49 and 50 can also only establish the connection to the internal contact 31 and the contact pin 47 of the socket part 46.
- the connections 42 and 43 of the disk isolating capacitor 41 are then soldered to other locations on the conductor tracks 38 or 39 or 44 or 45.
- the conductor tracks can form additional inductances if necessary.
- the number of external isolating capacitors 20 and thus also the axial dimension of the isolating member depends on the required capacitance between the outer sleeve 10 and the inner sleeve 13.
- the diameter of the outer sleeve 10 and the inner sleeve 13 are also significantly influenced by the RF coupling between these two Sharing is required.
