Definitions

  • the invention relates to a connection device for data transmission lines, in particular for a data network, with at least one plug device with plug contacts, in which a socket and a plug interact.
  • a data transmission line which include networks of data processing systems as well as other transmission lines of mostly high-frequency signals, such as video signals, etc.
  • high-frequency signals are usually transmitted, the transmission accuracy of which is subject to high demands because even minor interference can have serious consequences.
  • the cables are mostly coaxial cables with shielding.
  • connection resistance ratios are often very critical, and it is usually not possible to branch off from a continuous cable run without special measures.
  • a data network usually has to be looped through from one system to another, i.e. a line must run to one device and from there to the next device.
  • connection device From DE-U-89 08 236 a connection device has become known in which a conventional telephone socket is used as a through-junction box. It contains contacts in the socket, which normally abut one another and are simultaneously separated from each other when the plug is inserted and connected to the corresponding contacts on the plug. From there, a double, appropriately shielded cable runs to a coaxial connector in the form of a BNC connector, which can be connected to a corresponding BNC socket of the connected device.
  • the junction box itself is also connected to the data bus via BNC connectors.
  • connection device ensures that the data bus, which is disconnected when a cable is plugged in for a connected device and is passed through the device, is closed and forwarded again when the plug is pulled out.
  • connection contacts designed as flat plug connections are not sufficiently reliably contacted for data lines, and there is no complete shielding. This is particularly critical because such sockets are usually laid on cable ducts that also carry power lines, so that the susceptibility to interference signals is particularly high.
  • DE-A-27 07 250 which corresponds to the general term, shows a plug connection with an integrated switch which is actuated by the center socket of the coaxial plug. This is sprung axially movable and lifts a ring from a ring contact. The socket is short-circuited when not connected to a plug.
  • US-A 3 873 785 shows a coaxial plug-in device in which a terminating resistor is connected to a switch actuated by axial movement in the form of a contact spring and can thus be switched on.
  • the invention aims to provide a connection device for data transmission lines that works very reliably and fail-safe due to another solution principle and is optimally adaptable to the network and the connection devices with a small size.
  • the type of BNC coaxial plug-in connection with an internal contact and a shield-external contact insulated from it have an intermediate contact surrounding the internal contact and separated from it by insulation.
  • a total of three-pole coaxial connector thus makes no significant additional production costs and enables the connection of connections to data networks in particular, but is also useful for other purposes, for example for stereo connections, separate video and audio or other connections with two shielded conductors.
  • one of the plug contacts can be arranged in an axially movable manner when the plug device is plugged together and can be provided with a switching contact actuated during axial movement.
  • This enables the disconnection of the data bus, which is carried along a wall, for example, when a connector is inserted, and when this connector is disconnected, the line closes again and can thus supply the further devices.
  • This is possible in a coaxial plug connection, preferably with locking in the axial direction by means of a screw or bayonet lock, which is ideally, namely completely, shielded.
  • a terminating resistor which is automatically switched on when the plug connection is disconnected can be provided in the plug device his. This can be switched in the same way through an axially displaceable central sleeve without taking up any additional space.
  • a particularly preferred embodiment connects such a 2-conductor plug connection with two conventional plug connections, for example BNC plug connections, in a T-shape to form a connection unit in which the data bus is connected on both sides via conventional BNC connections and the connecting lines can be connected with automatic switching .
  • two conventional plug connections for example BNC plug connections
  • the connecting lines can be connected with automatic switching .
  • FIG. 1 and 2 each show a socket 12 of a plug-in device 11 designed as a built-in socket.
  • a plug 13 (FIG. 2) can be connected to the socket.
  • the plug device is designed in the manner of a BNC plug connection and has an inner contact sleeve 14 on the socket 12, which is surrounded at a distance by a sleeve forming a shielding outer contact 15, which has two lateral projecting pins 16 for a bayonet lock 17, to which an angle more curved Slot 18 belongs to a locking sleeve 19 of the plug 13.
  • This sleeve is rotatably mounted on the housing 22 of the plug with the interposition of an annular disc 20 and a spring ring 21.
  • the inner contact sleeve 14 is slotted so that it can be expanded and cooperates with an inner contact 23 of the plug designed in the manner of an axial central pin.
  • the inner contact sleeve 14 is located at the end of an axially displaceably mounted central pin 25 in an insulating insert 24 of the socket, onto which a ring 26 is pressed on the side of the insulating insert 24 opposite the inner contact sleeve 14 at a distance from the end 27 of the central pin 25.
  • the ring 26, flange 30 and the compression spring 28 lie in a space 33 of an insulating body 34 which is designed in the manner of a blind bore and which is fastened to a metallic outer body 36 by means of an overlapping fastening sleeve 35.
  • the inner contact sleeve 14 is surrounded by an insulating tube 48, which in turn is surrounded by a sleeve or tubular intermediate contact 50. Over the insulating body 24, which this unit penetrates, it projects that it surrounds the inner sleeve up to close to its end on the connection side.
  • the intermediate contact sleeve 50 is on its distal end a flange 52, which lies in a corresponding recess of the insulating body 24 and via a line 53 to the inner conductor pin 54 of a conventional BNC connector, but which is designed here without a locking bayonet sleeve.
  • the BNC plug devices 54, 56 and the socket 12 form an overall T-shaped unit 70.
  • the two BNC connectors 55, 56 are inserted into a transverse bore of a tubular metal housing part 35 which is closed at its free end. The result is a very compact unit, the possible uses of which are described in more detail with reference to FIGS. 4 to 6.
  • the axially movable central pin 25, which has at its end the slotted inner contact sleeve 14 which is slightly tapered in the non-connected state, lies with the contact shoulder 42 of its ring 26 in the uncoupled state (FIG. 1) on the flange 52 and thus connects the inner connections 54 , 57 of the BNC connectors 55, 56 electrically to one another.
  • the inner conductor pin 23, the inner contact sleeve 14 and the central pin 25 move axially against the force of the spring 28, and the switch contact 10 is opened via the contact shoulder 42, so that the inner conductor 14th , 23 is only connected to the inner sleeve 57 of the socket 56, while the intermediate contact 50 is connected to the inner conductor pin 54 of the plug 55.
  • the insulating insert 24 can have a lateral, axially directed recess 39, in which an electrical resistor 40 is received in the manner of a subminiature resistor. It is fixed between the outer body 35, the sleeve-shaped shielding external contact 15 and the insulating body 34 in such a way that it makes electrical contact with the shielding external contact with one end face, while the other contactable end face 41 is overlapped in part by the insulating body 35 for fixing purposes. while on the other end face part which forms a support shoulder 42, in the drawing the lower annular surface of the ring 26 is supported in contact. A switching contact 10 is thus formed.
  • the plug 13 shown in FIG. 2 contains its internal contact 23 designed as a central pin in the recess of an insulating body 43, on the outside of which a shielding external contact sleeve 44 runs, which is slit lengthwise, so that individual contact tabs or tongues form on the upper, free side have outer thickenings 45.
  • the plug 13 shown in Fig. 2 contains a slotted and thus resilient inner contact sleeve 60, which is arranged inside the tubular insulating body 43 and is insulated from the inside contact 23 on the one hand by an air space and on the other hand by an insulating insert 61.
  • this intermediate contact sleeve 60 cooperates with the intermediate contact 50, so that there is a plug connection in the three contact levels are coaxial to each other.
  • a sufficient contact pressure is possible by slitting and expanding the intermediate contact sleeve 60 inwards.
  • Inner conductor 23 and intermediate contact 26 are connected to separate connecting lugs 62, 63, which in the present case lie in the interior of a connecting piece 65 running transversely to the plugging direction (axis 64), into which a coaxial cable is inserted through a connecting opening 66.
  • a very space-saving and stable angled plug is thus formed.
  • the socket is provided, for example, on a data processing device for its connection to a line network or to a corresponding connection socket
  • the switch contact 10 in the uncoupled state provides an electrical connection between the inner contact 25 and the metallic one via the resistor 40 Housing of the socket, and thus also the mass of the device housing and the shield. This saves the special attachment of a terminating plug provided with the corresponding connecting resistor (FIG. 3) or a short-circuit device when a connecting cable is removed. This is necessary in particular in the case of devices with several connection sockets, in order not to interfere with the data processing.
  • a terminating resistor is automatically switched on and off.
  • the resistor and its switching device are housed in a housing the size of a normal BNC socket.
  • the axial stroke of the central pin 25 can be significantly less than shown.
  • FIG. 4 and 5 show a wall junction box, which are provided with two connection units 70 corresponding to FIG. 1. It can be seen that the two T-shaped units 70 each with a BNC connector 55 and 56 immediately are put together so that they have the basic shape of the Greek letter pi.
  • Two sockets 12 protrude side by side from a front plate 71 of the wall socket 72.
  • the outer body 36 holds between its flanged flange-like collar and a ring nut 38 screwed onto its external thread an insulating connecting bridge or plate 73 which fix the assembled units 70 to one another in such a way that the two bushings 12 run parallel to one another.
  • the connecting plate 73 also serves to hold an edge fastening part 74 which can be used in a conventional wall junction box.
  • connection sockets 12 can be arranged next to one another, whereby these can be arranged parallel to one another, but also at any angle.
  • a terminal block could have sockets on several sides, in that the sockets 12 are each offset at an angle of, for example, 90 or 180 ° from the adjacent socket.
  • a continuous data transmission line data bus
  • the bayonet lock 17 By locking by means of the bayonet lock 17, the very compact and stable connection connections also secured against accidental loosening, which is particularly important when transferring data.
  • a connecting cable 75 leads to the connected device from the respective connecting socket 12, which consists of a plug 13 according to FIG. 4, a shielded connecting line 76 with two inner conductors 77, 78 and a normal BNC plug 13 according to FIG. 2.
  • the two inner conductors are connected separately from one another to the connecting lugs 62, 63 of the plug 13, but are connected together in the BNC plug 13 to its central connecting pin 23. It has been shown that this separate guidance is important until shortly before the processing device for the purpose of adaptation.
  • the shield 79 of the connecting line is fastened to the plug housing by a crimping or compression sleeve 80.
  • novel plug connections 12, 13 with coaxial intermediate contacts 50, 60 are partially compatible with normal BNC plugs.
  • a BNC plug 13 can also be connected to a socket 12, the intermediate contact 50 then remaining unoccupied.
  • An embodiment with a terminating resistor according to FIG. 3 could also be used in the junction box or the connecting cables, although this is not necessary per se in the through junction box 72.
