Definitions

  • the invention relates to a jumper for electrical connection and / or connection terminals, in particular terminal blocks, for resilient engagement in openings in busbars and for electrically contacting busbars at least two connection and / or connection terminals, with a bridge rail, wherein the bridge rail a rail and a plurality having plug connected to the bus bar and wherein each plug has at least two substantially mutually parallel contact legs, of which at least one is resilient.
  • the invention also relates to an electrical connection and / or connection terminals, in particular terminal blocks, with a housing, with at least one busbar, with at least two connecting elements and with a detachable jumper.
  • connection and / or connection terminals have been known for decades and are used a million times in the wiring of electrical systems and devices.
  • the terminals are usually snapped onto mounting rails, which in turn are often arranged in a plurality in a control cabinet.
  • conductor connection elements predominantly screw terminals or tension spring terminals are used in terminal blocks.
  • the clamping principle with tension spring clamps is similar to that of screwdriving technology. While with the screw terminal a tension sleeve pulls the conductor against the current bar by the operation of the clamping screw, this task is taken over by the tension spring at the tension spring clamp.
  • there are also known terminal blocks whose conductor connection elements have cutting blades which cut through the insulation of the inserted conductors and contact the core of the conductor.
  • Electrical terminal blocks are usually connection terminals, so that they have at least two conductor connection elements which are electrically connected to one another via an electrically conductive connection rail, the busbar. Such terminal blocks are also referred to as feed-through terminals. In addition to this basic type of terminal blocks, there are In addition, a variety of different types of terminal block, which are specially adapted to the particular application. As an example, two-storey, three-storey or four-storey terminals as well as three-conductor or four-conductor terminals may be mentioned, which then each have a correspondingly larger number of conductor connection elements.
  • Double-decker, three-storey or four-storey terminals which are generally also referred to as floor terminals, have two, three or four bus bars arranged one above the other, arranged in different levels, which each electrically connect two conductor connection elements to one another.
  • a jumper described at the outset or an electrical connection and / or connection terminal described in the introduction is known, for example, from US Pat DE 44 11 306 C1 known.
  • the known jumper is characterized in that it comprises two juxtaposed bridge rail sections, on each of which a contact leg per plug is formed, wherein the spring loading of the plug is parallel to the longitudinal direction of the rail.
  • the two bridge rail sections may be simple stampings, so that the known jumper can be easily made.
  • From the DE 42 23 540 A1 is also a jumper known, but in which the spring forces of the contact legs are aligned transversely to the longitudinal direction of the rail strip when plugged into the opening of the busbars.
  • Both known jumpers is common, however, that they can only be used when the same types of terminal blocks are lined up. For example, a plurality of identical through terminals can be electrically connected to each other with such jumpers.
  • the known jumper consists of two juxtaposed spring contacts, which have in the region of their upper, cooperating with the upper busbar contact zone in opposite directions to each other directed cranks. This results in the insertion of the jumper in the two openings of the two busbars to a resilient, opposing spreading of the two spring contacts in the opening of the upper and lower busbar, whereby the jumper contacts the two busbars.
  • the present invention is based on the object to provide a jumper for electrical connection and / or connection terminals, which makes it possible to connect different types of terminal blocks, in particular those terminal blocks with different conductor connection elements with each other.
  • the busbars are arranged higher than in such terminal blocks, in which the conductor connection elements are designed as tension spring terminals or as a cutting blade.
  • the relative height difference of the busbars refers to the distance between the individual busbars to the mounting rail with two adjacent to each other on a mounting rail snapped terminal blocks.
  • the plug or the contact legs have different widths, wherein the width of a plug is adapted to the width of the busbar or to the width of the opening in the busbar.
  • the individual contact legs of a plug are the same width, so that all the contact legs of a plug are narrower than the contact legs of another plug.
  • the jumper according to the invention also two - or more - terminals to connect with each other, which are provided for connecting conductors with different conductor cross-sections. If a conductor with a larger conductor cross-section is to be connected to a terminal block, then this terminal usually also has a busbar with a greater width and thus also wider openings due to the higher currents flowing through the thicker conductors.
  • the bridge rail is designed so that the spring forces of the plug or the contact legs are directed parallel to the longitudinal direction of the rail strip when plugged into the openings of the busbar and when contacting the busbar.
  • the principle of contacting a busbar thus corresponds essentially to the contacting principle of the DE 44 11 306 C1 known jumper.
  • the jumper according to the invention advantageously has three substantially mutually parallel contact legs, of which at least the middle contact leg is resilient. If only the middle contact limb is resiliently formed - and the two outer contact limbs are relatively stiff - twisting of the jumper perpendicular to the longitudinal direction of the rail strip and thus perpendicular to the longitudinal direction of the jumper is prevented, whereby the insertion of the jumper into a plurality of juxtaposed Terminal blocks is facilitated.
  • a longitudinal slot is formed in at least one contact leg.
  • at least the middle contact leg is provided with the longitudinal slot. Due to the design of the longitudinal slot, the restoring force is reduced due to the deflection of the contact leg when inserted into the opening of the busbar, which in particular reduces the insertion force in the upper contact area, so that the insertion or penetration force through the opening of an upper busbar hardly from the Insertion force into an opening in a lower busbar is different.
  • the contact legs below the lower contact area on at least one narrow side of a run-on slope are further facilitated.
  • the lower contact area can be limited upwards by a laterally projecting offset, so that with a corresponding dimensioning of the opening a defined insertion of the jumper is ensured in the terminal block.
  • the busbar has an opening for resilient engagement and electrical contacting a jumper
  • the above-described object is achieved in that in the jumper, a bridge rail having a rail and a plurality of connectors connected to the rail connector, the connector has two superimposed contact areas for contacting two arranged on different levels busbars of two juxtaposed connection and / or connection terminals.
  • the jumper for electrically connecting two juxtaposed connection and / or connection terminals is formed, it is, of course, possible to connect with the connector also significantly more than just two connection and / or connection terminals with one another , On the other hand, it is not necessary that the connecting and / or connecting terminals to be electrically connected to each other are arranged directly next to each other. In particular, it is also possible to connect only a few specific, for example, the first, third, fourth, seventh and tenth terminal block by a correspondingly formed jumper in a plurality of latched on a mounting rail terminal blocks.
  • the distances between the individual connectors are formed accordingly, which can preferably be realized in that the corresponding to the terminal blocks, which are not to be electrically connected, corresponding plug are removed, including in the transition region between the rail and the individual Plugs corresponding predetermined breaking points are provided.
  • Each busbar 3, 30 is arranged in a housing of the electrical terminal block and serves for the electrically conductive connection of two terminal elements of the terminal block.
  • the bus bar 3 is one typically used in terminal blocks with spring-loaded terminals, while the bus bar 30 is one such bus bar used in terminal blocks with screw terminals.
  • the jumper 1 has a comb-like bridge rail which has an upper rail strip 5 (FIG. Fig. 7 .) And a plurality of connected to the rail bar 5 6 plugs.
  • a comb-like bridge rail which has an upper rail strip 5 (FIG. Fig. 7 .) And a plurality of connected to the rail bar 5 6 plugs.
  • only two plugs 6 are shown per bridge rail 4, so that with the jumpers 1 shown, only two busbars 3, 30 of two terminal blocks can be electrically connected. It is understood that, of course, far more than two plugs can be provided.
  • each plug 6 has two separate contact legs 7, 8.
  • each plug 6 three contact legs 7, 8, 9 on. Assign the plug 6 of the jumpers 1 only two contact legs 7, 8, so preferably both contact legs 7, 8 are resilient. If, however, the plugs 6 have three contact legs 7, 8, 9, then preferably only the middle contact leg 9 is resilient formed while the two outer contact legs 7, 8 are relatively stiff.
  • All plugs 6 and all jumpers 1 have in common that they have two superimposed contact areas 10, 11, so that there is the possibility of two at different levels I, II arranged busbars 3, 30 of two juxtaposed terminal blocks to electrically connect with each other.
  • plug 6 or the contact legs 7, 8, 9 in the openings 2 of the busbars 3, 30 contact the connector 6 in the longitudinal direction L of the rail bar 5.
  • the longitudinal direction L of the rail bar 5 and the jumper 1 is approximately perpendicular to Longitudinal direction of the busbars 3, 30.
  • the above-described direction of the spring forces occurring through the plug 6 when inserting the plug 6 in the openings 2 is achieved in that the plug 6 in the unloaded state, ie in the non-inserted state, have a width which is greater than the width of the opening. 2 is.
  • the middle contact leg 9 in the longitudinal direction L of the rail strip 5 slightly offset from the two outer contact legs 7, 8 are arranged. This ensures that when inserting the plug 6 in the opening 2 of the busbars 3, 30 only the middle contact leg 9 is deflected, whereby a distortion of the jumper 1 is prevented perpendicular to the longitudinal direction L.
  • the insertion of a jumper 1 with a plurality of plugs 6 facilitates in a corresponding number of terminal blocks.
  • the embodiments according to the Fig. 1 to 3 differ by the use of each identical jumper 1 together with different busbars 3, 30, ie by the use of different terminal blocks.
  • the embodiment according to Fig. 1 is the - in the drawing plane - front plug 6 inserted into an opening 2 of a busbar 3 of a terminal with spring clips, while - in the drawing plane - rear plug 6 is inserted into an opening 2 of a busbar 30 a terminal with screw terminals.
  • the Busbar 3 is located on a lower level I, while the busbar 30 is located on an upper level II.
  • the busbar 3 is contacted in the lower contact region 10 of a plug 6 of the jumper 1, while the busbar 30 is contacted in the upper contact region 11 of the second connector 6 of the jumper 1.
  • jumper 1 is the - in the plane of the drawing - front plug 6 slightly narrower than the rear connector 6, since in the embodiments shown there, the front busbar 3, 30 is also narrower than the rear busbar 30, 3.
  • the width of the plug 6 is always matched to the width of the opening 2 in the busbar 3, 30. Since the different terminal blocks have only a limited number of different busbar widths, a total of only a few jumpers 1 with different combinations of connector widths are required to connect almost all types of different terminal blocks with each other.
  • the middle contact leg 9 has a longitudinal slot 12.
  • the longitudinal section 12 extends from a region slightly above the lower contact region 10 to a region slightly above the upper contact region 11.
  • the formation of the slot 12 in the contact leg 9, the restoring force of the contact leg 9 slightly reduced, whereby the force required when inserting the plug 6 through the opening 2 of a bus bar 30 in the upper level II is reduced.
  • an insertion force can thereby be achieved, which is substantially constant, regardless of whether a plug 6 in an opening 2 of a busbar 3 in the lower level I or in an opening 2 of a busbar 30 in the upper Level II is inserted.
  • the contact legs 7, 8, 9 are formed such that their width B is greater than their thickness D.
  • a relatively narrow plug-in bridge 1 can be realized, on the other hand sufficiently large spring forces at a load of the contact legs 7, 8, 9 in the longitudinal direction L of the rail strip 5, so that a sufficient contact force is ensured.
