Definitions

  • the invention relates to a terminal block arrangement, in particular an initiator terminal arrangement, consisting of a plurality of series terminals, each with at least one perforated busbar and with a cross connector, consisting of a crossbar running over the terminal blocks and from there to the perforated busbars, inserted into the holes.
  • cross connectors are known (DE 33 12 002 C1), in which tabs are formed on the cross bar running over the terminal block arrangement in a comb-like variety and arrangement, with the tabs in holes in the Busbar of those terminal blocks that are to be switched to this potential.
  • Flat plugs that are not required in accordance with those terminal blocks in the arrangement that are not to be switched to this potential can be broken off from the crossbar during assembly via a predetermined breaking point.
  • the known design is simple in terms of assembly, but on the other hand is not very flexible in the area of use. After their first installation, for example in a switchgear, changes are no longer possible. In the event of changes in the circuit arrangement, a new comb-type cross connector must generally be used.
  • the entire comb-like cross connector must also be removed, so that practically the entire circuit system and the units to be supplied attached to it are switched off.
  • the tabs in their lower area interacting with the perforated busbar are formed to a certain extent by an expansion slot so that they can be inserted into the hole in the busbar with slight compression.
  • the contact force that can be achieved in this way is limited and must also be the case when a large number of tab connectors are normally inserted at the same time during the assembly process or have to be pulled out again when the connection is released.
  • a cross connector arrangement is known (DE 27 36 664 A1), in which the busbars each have two plug-in openings oriented in a row with row terminals connected in series.
  • a large number of U-shaped cross connector plug elements are provided as cross connectors, which are designed in the manner of a flat plug, one leg of the U-shaped plug connector in each case in a hole in a busbar and the other leg in the closest hole in the busbar of the adjacent terminal block is stuck.
  • a cross connector element must always be inserted in a seamless sequence from terminal block to terminal block.
  • the low flexibility is also a particular disadvantage here.
  • All terminal blocks of the arrangement must be switched to the same potential, since if such a cross connector is omitted, the terminal blocks behind in the current flow direction can no longer be switched to this potential due to this interruption. If you release a cross connector in an existing arrangement, all the terminal blocks behind are automatically de-energized.
  • cross connectors are known in which a plurality of spacing or connecting elements extend from a cross bar to the busbars of the terminal blocks, sometimes also over predetermined breaking points, the elements reaching to the busbars carrying a connecting screw and the busbar having a threaded hole (DE 23 57 052 A1).
  • Such cross connectors are expensive to manufacture, in particular because they require a threaded hole in the busbar. It takes a lot of time to make the screw connections.
  • flexibility is conceivably low, since a transverse bar that has been set up cannot be used again when the circuit arrangement is changed. It is also not sensible to loosen individual cross-connection connections of affected terminal blocks.
  • the present invention is therefore based on the object of providing a modular terminal arrangement of the generic type which is particularly flexible in the region of the cross connector with regard to changes in circuit arrangement and with regard to a desired release of the connection.
  • the solution according to the invention consists in a modular terminal arrangement of the generic type in that the flat plugs are designed as separate plugs which can be placed on the crossbar and are placed on them.
  • isolating plugs can be placed in any arrangement on the crossbar leading over the terminal block arrangement and, like the known flat plugs, can be inserted with their lower ends into the holes in the affected busbars.
  • This assembly and insertion is a simple process in terms of assembly.
  • the individual cross-connection connections of the individual terminal blocks are and remain independent of each other. If a change in the circuit arrangement is required, the same isolating plugs can be used in the series, where necessary with other terminal blocks. It is particularly possible in a very simple way to open a single cross connector connection of an affected terminal block in the sense of disconnection from the circuit, without affecting the power supply to all other terminal blocks in the arrangement, including those that use the same cross connector Are switched, has some influence. This gives the cross connector flat connector a dual function.
  • the flat plug is designed to be placed on the crossbar, its basic structure can also be designed to be elastically spreadable when it is placed on the crossbar, so that in conjunction with the hole in the affected conductor rail, a very high resilient contact force for the inserted flat connector or isolating plug can be achieved, as is the case in many applications, for example with strong vibratory loads and / or downward arrangement of the terminal block arrangement as a whole.
  • the configuration according to the invention is particularly suitable for so-called initiator terminal block arrangements.
  • initiator terminal block arrangements EP 0 222 030 A1
  • three-tier terminals are used.
  • the first terminal block of the series is connected to the positive pole and the negative pole of the voltage source in the two-tier arrangement.
  • the forwarding then takes place exclusively via cross connectors on the individual floors.
  • the conductors then going out on the two floors lead to initiators and back from them, while the initiators then feed the remaining floor via a control line and the rear connections of this floor are then connected to signal transmitters.
  • FIG. 1 shows a three-tier terminal block as used in the context of initiator terminal arrangements.
  • a first electrical connection 2 which is for example a spring plug connection, is provided, into which the electrical conductor 3 coming from the positive pole of a voltage source (not shown) is inserted.
  • the electrical connection 2 is connected to a busbar 4, which is arranged at an angle in the terminal housing 1 in such a way that it has an area below a plug opening 5 provided in the terminal housing 1, in which it has a hole 4a.
  • a modular terminal arrangement In a modular terminal arrangement according to the invention, many such modular terminals are lined up next to one another, for which purpose they are, for example a common mounting rail (not shown) are snapped on.
  • a cross bar 6 is now guided as part of a cross connector through the plug openings 5 of the terminal housings 1 of the clamped strings, which are therefore aligned.
  • the cross bar 6 thus serves to supply power to the positive connections of all terminal blocks of the series, at least those terminal blocks in this arrangement which must be switched to this potential.
  • separate individual tabs 7 are provided from the cross bar 6, which have a downward-opening expansion slot 8, with which they can be used on the continuous cross bar 6 wherever the cross connection connection is desired , can be put on.
  • the inner walls of the expansion slot 8 also have expansion knobs, which interact when the crossbar 6 is placed on them and which allow a targeted elastic expansion of the lower region of the flat connector 7, which lower region in turn then closes the circuit into the hole 4a of the person concerned Busbar 4 of the affected terminal block is inserted. Thanks to the resilient design and thanks to the spreading of the tab 7 through the cross bar 6, a targeted very high electrical contact force can be guaranteed.
  • the flat connector 7 also has a handle 10 in its upper region.
  • the flat connector 7 has a narrow frame 11 which surrounds the actual flat connector part and consists of electrically conductive material and which carries the handle 10 on the upper side.
  • Frame 11 and handle 10 are made of an insulating material and form a protection against contact.
  • locking knobs 12 are provided on the frame 11 on both sides.
  • a latching recess 13 is provided on both sides in the inner wall area of the plug opening 5.
  • the upper locking knobs 12 engage in the locking recesses 13 and bring about a mechanical locking of the insertion position. If you pull the tab 7 out of the hole 4a of the busbar 4 to release the connection, you can lock the lower locking knobs 12 in these locking recesses 13 and thus have a mechanical, loss-proof hold in the disconnected or interrupted position.
  • tabs 7 also act as isolating plugs in the sense of forming the terminal block concerned as an isolating terminal.
  • the terminal block provided in the illustrated embodiment has a further electrical connection 14, into which, for example, the conductor 15 coming from the negative pole of a voltage source (not shown) can be inserted.
  • the electrical connection 14 in turn has a busbar 4 which has a hole 4a.
  • the arrangement is also made here so that the hole 4a of this busbar 4 is located under a plug opening 5a in the terminal housing 1.
  • a cross bar 6 is in turn guided, which, if desired, can be equipped with the previously described, at the same time enabling separation flat tabs 7, which then also here again in the hole 4a of the affected person Engage busbar 4.
  • FIG. 2 the arrangement is illustrated only for the one cross connector area consisting of the cross bar and a plurality of flat plugs 7.
  • One of the tabs 7 is shown for illustration in the raised disconnected position.
  • control signals still come from the initiators, which must be routed to special signal transmitters (not shown).
  • the terminal blocks then have a further electrical connection 15 in their terminal housings, into which the electrical conductor 16 coming from the initiator is to be inserted.
  • the control current in the interior of the terminal blocks is in each case conducted via a conductor rail 17 to wide connections 18, 19, into which the electrical conductors leading to the signal transmitters can then be inserted.
  • terminal housing 1 can be snapped together on the common mounting rail 21 within the baying with the usual locking feet 20.
