Definitions

  • the invention relates to a connection system with at least one direct plug connection with a compression spring according to the preamble of claim 1.
  • Direct plug connections can be realized by means of compression springs, which press a conductor to be contacted against a busbar with a free clamping leg.
  • a type V is formed between the free clamping leg of the compression spring and the busbar in the contacted state, in the top of the conductor between the busbar and the free end of the clamping leg is clamped and contacted. It is also known to bend the free end of the clamping leg slightly against the direction of insertion for the conductor to ensure that the clamping leg abuts linearly against the edge of the conductor to increase the resistance to inadvertent release of the conductor from the nip.
  • the area to be contacted conductor is limited, in particular when the clamping leg is only pivotable by a small angle due to the geometric conditions.
  • the maximum pivot angle also determines the maximum possible diameter that the conductors to be contacted can have. This has the disadvantage that, for example, conductive pins of larger diameter are not contactable.
  • the clamping leg is provided with at least two different pressure ranges, each serving for contacting conductors of different cross-section. This makes it possible with the clamping spring both conductors smaller and conductors larger diameter to contact, since each of the two pressure ranges only comes with conductors of different diameters used.
  • one of the two pressure areas is formed by the free end of the clamping leg and further of the two pressure areas by a first bending area in the clamping leg.
  • a further oppositely directed bending region is formed in the clamping leg, so that the two bending regions together form a kind of S-curve, which means that even conductors with a particularly large diameter can be contacted in the clamping point.
  • the compression spring has a V-shape with a first fixed leg and an adjoining the first leg free clamping legs.
  • FIG. 1 to 3 are side views of a terminal block with a direct plug-in connection according to the invention, in each of which conductors of various types are inserted;
  • FIG. 4 - 6 direct plug connections, in each of which conductors of various types are inserted.
  • 1 shows a terminal block 1 with two direct plug connections 2 according to the invention.
  • a busbar 3 preferably a busbar 3 is arranged with u-shaped cross-section, which has a base leg 4 and two longitudinal legs 5 and the open area in the terminal upwards - at the side facing away from a support rail 21 - out is aligned ,
  • a compression spring 6 is arranged for each of the twoticiansteckan- inferior 2 (see also Fig. 4).
  • These compression springs 6 rest with a base leg 7 on the longitudinal legs 5 and each have a window-like recess 8 in the base leg 7.
  • a long drawn and looped bent region 9 follows, which merges into a free clamping leg 10 after a bending range of far more than 220 °, which passes through the recess 8 with its free end 11 and the movable in the recess 8 or is pivotable.
  • the size of the recess 8 thus limits the maximum pivoting range of the clamping leg 10, which in turn affects the diameter of the conductor to be contacted.
  • contact tabs 12 are bent inwardly into the interior of the U-shaped busbar, which serve as an abutment for the clamping legs 10.
  • the terminal In the terminal are upper -. facing away from the locking foot 20 for the support rail 21 - insertion 18, 19 designed for conductors and for actuating tools such as a screwdriver.
  • the screwdriver is only used to release the ladder.
  • the clamping leg has two separate clamping areas 11, 13, which serve in each case, conductors 14, 15, 16 (Fig. 1 - 6) of different diameters against the current rail - here the contact lugs 12 of the busbar 3 - to press, so that a secure and good contact between the conductors and 14 -16 and the busbar 3 is realized.
  • the insertion direction for the conductors 14-16 is designated X in FIG. Imports are usually done without tools simply by inserting the conductor in the nip between busbar 3 and clamping leg 10, wherein the clamping leg 10 deviates to the side until the head is sufficiently far inserted into the connection point for the realization of a good contact.
  • One of the two clamping regions is formed by the free end 11 of the clamping leg 10, which can be bent or bent opposite to the conductor insertion direction, in order to secure the conductor to be contacted against being pulled out.
  • This first pressure region 11 serves for contacting conductors 14 of a first smaller diameter region.
  • the further clamping region 13 is formed by a first bending region 22 in the clamping leg, which is located a small distance from the free end 11 of the clamping leg and its side facing the conductor is concave and its applied by the conductor side is convex.
  • the conductor 15 may be a pin-like contact tip of a plug-type terminal 17 (Fig. 2 or 3), e.g. serves to make a transition to another type of connection (here tension spring), or it may simply be a conductor with a particularly large diameter (Fig. 5).
  • Fig. 4 illustrates the position of the clamping leg 10 by way of example for two conductor diameters.
  • the diameter range of conductors to be contacted is increased by the fact that the pressure range 13 or the convex bending range is oppositely offset.
  • directed further bending region 23 in the clamping leg 10 is upstream, so that the two bending areas give the free clamping leg 10 an S-curve-like course with elongated S-curve geometry.
  • the further bending region 23 is arranged approximately in the middle of the free clamping leg 10.
  • the first bending region forming the pressure region 13 is only a few mm - less than 10 mm - or close to the free end 10 of the clamping leg
