Definitions

  • the invention is specifically concerned with Terminal connection for stripping-free connection of enamelled wires or plastic insulated Wire conductors and it can be left whether a terminal of this type has other terminal connections for stripping-free connection electrical conductor or other terminal connections have that known with another Connection technology work, for example one Screw terminal connection or another Spring clamp connection for connecting of electrical conductors, the end of their conductors has been stripped beforehand.
  • Terminals of the generic type are or known as feed-through terminals. They are often used as device or motor connection terminals used, but also as Terminal blocks on mounting rails or in shape of assembled from stackable individual terminals Terminal blocks or as ballasts and Transformer terminals or as other connection terminals, and always if at least on a connection side of the Clamp enamelled wires using a Ablack clamp connection or plastic-coated conductors free of stripping by means of a insulation displacement connection should be wired.
  • the insulating housing of the terminal accordingly be adapted and suitable housing open Insertion slots for pushing the Provide wire conductor (cf. DE 43 12 778 A1). Pushing in the wire conductor can be done both manually using an insertion tool as well as fully automatic by means of an automatic wiring machine.
  • Winding wires e.g. motor windings or from transformer windings
  • a bandwidth the diameter of e.g. 0.18 mm to e.g. 1.2 mm are present.
  • Such a range of Diameter is with the previously known Ablack clamp connections not to process especially not if between the opposing clamping edges of the same Terminal connection two or more enamelled wires with different wire diameters to be clamped.
  • the invention described below lies based on the task of having a terminal connection two opposing clamping edges for the stripping-free connection of enamelled wires or plastic-coated wire conductors to create a wide range of wire diameters can process and which still has a very small width, so that it also in narrow terminal blocks or other terminals with small sizes can be used is.
  • an austenitic chrome nickel spring steel is made, the clamping edge of the contact post as a tool for Paint stripping or as a cutting tool the conductor insulation is formed and the Clamping edge of the clamp spring the function of the Press the conductor against the clamping edge of the Contact post takes over.
  • Preferred embodiments of the invention are that the clamping spring as a U-shaped leaf spring is formed, in which the current carrying Contact post with parallel alignment stretched into the back of the leaf spring (see claim 3) and that the Clamping edge of the clamping spring in the form of a wide area Press-on skid is formed (see claim 4).
  • a stiff contact post can be made relatively narrow in cross section. It is live and at the same time the tool for stripping and cutting through one Conductor insulation. This has considerable advantages in terms of size.
  • the stiff contact post does not spring and therefore does not need any constructive movement spaces. It can edge be positioned on the track, so the remaining width of the busbar sufficient to clamp the one to be clamped there Wire conductor and the pull-off clamping edge of the clamping spring to arrange. Because at the same time the shape the clamping spring largely independent of the shape of the contact post, the clamping spring can be shaped so that its Outer contours essentially within the Width of the conductor rail.
  • the power line from the clamping force generation Cut that also leaves the best possible Material selection for the clamping spring too.
  • the aforementioned independent Shape of the clamping spring is thus ensures that the spring force characteristic the clamping spring for a wide range of Diameter of the wire conductor to be clamped can be interpreted in such a way that the clamping force of the pressure clamping edge the clamping spring automatically the respective Adapts the diameter of the conductor to be clamped.
  • the insulation remains despite the high clamping forces of the conductor on the side of the pressure clamping edge the clamping spring free of damage, in particular then when the pressure clamping edge in the form of a wide-area pressure skid is trained. That has the advantage, that with a clamp whose clamp spring is not is under voltage (e.g. because it stored in the insulating housing of the terminal and is guided) the clearance and creepage distance to an adjacent terminal on the facing away from the live contact post Side (this is the side of the pressure clamping edge the clamping spring) is easy to maintain, even with terminals with a very narrow width.
  • the new terminal connection can be on one multiple live contact posts be, for example, storied be arranged one above the other (as a 2-wire terminal connection, see claim 2), or it can with the same connection technology (and if desired) also a multi-conductor terminal connection are manufactured at the live contact post in the middle between the two clamping legs e.g. U-shaped leaf spring is set so that one on each side of the contact post Terminal point for conductors with different ones Result in conductor diameters.
  • a busbar 2 is shown which is connected to each of its ends has conductor terminal connections 3 and 4 has and those in the usual and known Way inside the housing in an insulating housing (not shown) is arranged.
  • Such Busbars usually also have one Plug receptacle 5 for receiving the plug contacts a cross bridge by means of which the busbars of clamps arranged adjacent to each other are electrically bridged.
  • the conductor terminal connection 3 is also known Type and described in more detail in DE 196 41 206 C2. This terminal connection is used for connection from conductor ends that were stripped beforehand have been.
  • the terminal connection consists of the end piece 6 of the busbar 2 and one Clamp spring 7 shaped in the manner of a loop and one on the conductor rail Contact leg 8 and a clamping leg 9 having.
  • the clamping leg has one Window recess through which the headboard extends of the conductor rail end piece extends through such that the outer clamping edge the window recess one between the bottom of the track end and the clamping edge of the window recess inserted electrical conductor (not shown) against the bottom of the track end stuck.
  • Fig. 1 at the right end of the busbar shown two terminal connections essential. Both terminal connections are identical executed, but suitable, electrical Conductors with a very wide range of Clamp conductor diameters.
  • Fig. 1 are two clamped for demonstration purposes electrical conductors 10 and 11 shown, whose diameters are clearly different from each other are.
  • Each of the two terminal connections consists of the end piece of the busbar and one own leaf spring 12 and 13.
  • the end piece the busbar is in shape according to the invention a stiff contact post 14 trained, the width of which is narrower than the width of the busbar 2.
  • each of above and one after the other in their illustrated Clamping positions are pressed in (by means of the tip of a screwdriver or by means of a flat slide piece or by means of a special indentation tool that to the existing constructive spaces is adapted) offers the contact post 14th a protruding clamping edge 15 which, depending on Application (enamelled wire to be jammed or jammed plastic-coated Conductor) as a stripping tool or as a tool for cutting through the conductor insulation is trained.
  • Application encoded wire to be jammed or jammed plastic-coated Conductor
  • the one opposite the contact post Clamping edge of the clamp connections are each from the free leg ends of the U-shaped Leaf spring 12 and 13 formed.
  • the non-free The end of the leaf springs is at the illustrated embodiment on the back the contact post fixed, for example through a protruding nose piece on Back of the contact post into a Recess of the leaf spring leg engages. Since the leaf spring is mounted pretensioned, it is self-retaining on the contact post.
  • the free leg ends of the leaf springs, the opposite of the contact post Forming clamping edges have the shape of wide areas Press-on skids 16 and 17 and each with a clear entry slope, see above that indenting the electrical conductor in the shown clamping positions without any problems is.
  • the position of the arrangement shown in Fig. 1 of the contact post at the end of the conductor rail and at the same time offset up to close to the right edge of the busbar (as shown) does not have to be for all embodiments the invention the most suitable arrangement his.
  • the contact post can also on one elsewhere along the track positioned, and several can be Contact posts along a conductor rail to be built there depending on the application Enamelled wires or plastic-coated Connect wire conductors without stripping.
