Definitions

  • the invention relates to a terminal block for connecting individual conductors to ribbon cables, with a terminal block containing the individual conductor connections, a ribbon cable connection and a fixable lower part receiving the terminal block and the ribbon cable connection.
  • Terminal blocks of the generic type which can also be referred to as transfer elements for ribbon cables, have hitherto been of a mechanically and in particular electrically complicated structure with many contact points.
  • the end of the ribbon cable to be connected is provided with one element of a multipole connector, the counterpart of which, for example the corresponding socket element of such a multipole connector, is provided with an appropriately printed circuit board.
  • the circuit board in turn is then mounted in a lower part made of insulating material, the lower part having, for example, snap-in feet for snapping onto standard mounting rails, or being provided with connecting angles for fixing on flat surfaces.
  • the terminal block which contains the individual conductor connections, is then also mounted on the circuit board itself.
  • the arrangement described above has contact points between the ribbon cables and the connector, in the connector itself, in the connection of one element of the connector to the circuit board, in the transition to the conductor track and in the outlet from this to the connecting pins in the terminal block, in the connection between the connecting pins Drawbar when designing the individual conductor connections, for example as screw connections and in the connection area of the individual conductor to be connected in the drawbar.
  • the arrangement is therefore not only mechanically complicated and consists of many parts, but is also electrically affected by considerable contact resistance due to the extremely high number of contact points.
  • the present invention is therefore based on the object of providing a terminal block of the generic type which is distinguished by a simple mechanical structure and by low contact resistances.
  • the solution according to the invention consists in that a push-through guide for the ribbon cable is provided in the lower part, to which individual conductor connections in the terminal block and insulation-penetrating contacts are assigned, for which guide channels are provided in the lower part to the push-through guide and the single conductor connections in the terminal block are designed in a manner according to the ribbon cable grid Grid offset are arranged.
  • the arrangement thus has a greatly simplified mechanical structure and is also characterized by a very small number of contact points, since now only contact points between the directly contacted ribbon cables and the insulation-penetrating contacts, and also in the terminal block, the contacts between the insulation-penetrating contacts and the tension clamps There are individual conductor connections as well as between the drawbars and the individual conductors to be connected. The contact resistances are consequently considerably reduced.
  • the terminal block As a result of the grid offset of the individual conductor connections in the terminal block, which is oriented on the ribbon cable grid, the latter is spatially very compact and small, so that there is therefore no need to fear housing problems for such a terminal block, for example in switchgear installations on a standard mounting rail.
  • the terminal block for connecting individual conductors to ribbon cables has a lower part 1 on which means for fixing it, for example detents 2 for locking it on a standard mounting rail, are provided.
  • means for fixing it for example detents 2 for locking it on a standard mounting rail.
  • fastening brackets or the like could also be provided on flat surfaces for fixing, for example screwing.
  • a push-through guide 4 is provided which is adapted to the size, in particular the width, of a ribbon cable 3 to be connected.
  • the lower part 1 can be formed in several parts and can have a special inner part which essentially defines the push-through guide 4, the push-through guides 4 then opening on the insertion side in a frame housing of the lower part 1, while the rear frame side of the lower part 1, which can be seen in Figure 2, can be closed so that the ribbon cable 3 can be inserted against the closed rear wall as a stop with a defined insertion depth.
  • the arrangement also includes the actual terminal block 5, in which the individual conductor connections 6 are accommodated. These can be formed, for example, from tension clips 7 with clamping screws 8. All individual conductor connections 6 in the terminal block 5 are now assigned contacts 9 which penetrate insulation, for example in the form of molded double-blade contacts which are molded onto the pulling bracket 5 and run downward through the terminal block 5 in the direction of the push-through guide 4. In the lower part 1 9 guide channels 10 are provided for all these insulation penetrating contacts, as shown in Figure 3.
  • This guide channels 10 open out first in the push-through guide 4, but are also extended a little beyond this downwards, so that the double knife after pressing into the ribbon cable 3 and the penetration of the insulation with appropriate contact with the relevant conductor of the ribbon cable convenient Have space, as is also illustrated in Figure 3, which shows this contact position.
  • both a pre-locking and an end locking are provided.
  • a latching lip 11 can be formed on the actual terminal block 5 on two opposite sides, for which two latching receptacles 12 and 13 arranged one above the other are provided on the corresponding inner wall area of the lower part 1.
  • the arrangement can be supplied by the manufacturer such that the locking lip 11 of the actual terminal block 5 is initially locked in the upper locking receptacle 12, in which position the double blades of the insulation-penetrating contacts 9 do not yet reach the push-through guide 4.
  • the double blades of the insulation-penetrating contacts 9 penetrate the insulation of the ribbon cable 3 while making contact simultaneous locking of this end position by snapping the locking lip 11 in the lower locking receptacle 13.
  • the individual conductor connections 6 in the actual terminal block 5 are arranged in a grid offset, which according to predetermined ribbon cable grid is designed.
  • a grid offset which according to predetermined ribbon cable grid is designed.
  • the offset between the first individual conductor connection 6 and the further three individual conductor connections 6 is then a, 2a and 3a, the width of a grid offset element as a whole or of a grid offset group being 4a.
  • the currently standard ribbon cable grid is 1.27 mm.
  • the offset dimensions of 1.27 mm, as well as double and triple thereof, can still be implemented well and the total width of a single grid offset element or a grid offset group is then 5.08 mm and thus a width at which the usual Design of the single conductor connections in the form of screw connections or spring connections can still be realized.
  • an actual terminal block 5 is illustrated, which is either formed as a whole in one piece from insulating material, or in which at least the four rows which are offset one behind the other correspond to FIG selected four offset levels are one-piece and then assembled elements.
  • terminal block 5 from individual disks 14, each individual disk then containing the four individual connections 6, offset in a corresponding grid, with the associated insulation-penetrating contacts 9.
