Definitions

  • the invention relates to a connecting terminal for electrical conductors according to the preamble of claim 1.
  • connection terminals are known for example from catalog No. 69 of the Wieland company, October 1968 edition, pages 5/5 and 5/10.
  • these two pieces can be completely moved into one another by actuating the clamping screw by the corresponding design of the pressure piece and counterpart.
  • the concave clamping zone for the conductors which converges concavely to the central longitudinal axis, also means that numerous wires of multi-wire conductors or numerous individual wires, including those of different diameters, are forced into a tapering zone of the clamping zone, compacted here and then, possibly also jammed, against one another will. It is also possible to clamp only a single, relatively thin individual wire in this clamping zone.
  • a pressure piece that can be moved by the clamping screw is located on the lower side of the clamping zone.
  • This pressure piece itself carries top-side inclined surfaces involved in the definition of the clamping zone.
  • a further separate clamping piece is provided above the actual clamping zone, which can enter like pliers through recesses in the pressure piece located below and movable by the clamping screw.
  • the upper clamping piece also has inclined surfaces which are involved in the formation of the clamping zone.
  • the known connecting clamp has more parts, since two separate clamping or pressure pieces are required to form the clamping zone and the corresponding inclined surfaces must be worked into these two relatively solid pressure pieces.
  • the clamping force by the clamping screw is always eccentric to the actual clamping zone, ie. H. the zone of engagement of the pressure piece and counterpart must be applied.
  • DE-C-11 16 294 shows a connecting terminal with which both single-wire and multi-wire conductors can be clamped.
  • inclined beads protruding inwards are formed in the middle area of the clamping body as a centering, for which corresponding impressions which completely accommodate them are provided on the pressure piece.
  • the present invention has for its object to provide a connecting clamp of the generic type, which makes it possible to achieve the functionally reliable clamping of solid and multi-wire and fine-stranded conductors in a large cross-sectional area with little design and manufacturing effort.
  • such a connecting clamp also enables the clamping force to be applied practically centrally to the clamping zone via the clamping screw.
  • a special embodiment is provided in such a way that a fillet extending over the entire clamping zone is incorporated into the central flattening of the tapering tip of the movable pressure piece. Together with the oppositely curved tapering tip of the clamping body, this fillet forms a collecting and centering receiving space for the individual wires, which are clamped here particularly reliably in a particularly reliable agglomeration.
  • the busbars and drawbar 1 shown in the figures also called clamp body 1, belong to a type of connection clamp in which two clamp connections are provided in an insulating housing, each of which has a hollow clamp body in the form of a drawbar 1, through which a clamping screw 2 is screwed on the top .
  • the conductive connection between the two tension clamps 1 of the two clamp connections is done by a busbar 3, the two ends of which are each in one of the tension clamps 1 and the ends of which thus form the pressure pieces, which are inserted or inserted by means of the clamping screws 2 placed on top of them Fix multi-wire conductors or several inserted conductors with their undersides to be clamped against the bottom area of the respective pull bracket 1.
  • the bottom region of the tension bow 1 has a concave taper converging towards the central axis, so that there are two bottom walls 4 which run obliquely downward towards the central bow longitudinal longitudinal axis, the snapping point of which forms the tapered tip 5, which is rounded.
  • the bottom walls 4 form a centering for the conductor to be clamped.
  • the associated pressure piece formed by the busbar 3 in the illustrated embodiment, is provided on both sides with corresponding tapering in the form of incorporated inclined surfaces 6, which converge towards the bottom of the busbar, the tapering tip here also having a flattening 7.
  • the dimensioning is chosen so that the corresponding busbar end can be pressed completely against the centering bottom of the tension bracket 1 from the tapering and sloping.
  • the inclined surfaces 6 are located on the underside of the busbar only in its clamping zone, that is to say the region which interacts with the tension bracket 1.
  • recesses 11 are also provided in its sloping bottom walls, which are dimensioned so large that they can completely accommodate the lugs 8, that is, the busbar despite the lugs 8 can still be completely pressed against the bottom of the drawbar 1.
  • these recesses are formed by corresponding embossed beads 12.
  • the busbar 3 has a section 13 adjacent to the clamping zones at its ends, which has the full busbar cross section.
  • the sections 13 lie on the conductor insertion side and can support the collection and merging effect of the lugs 8 in the central region of the clamping zone with their undersides. This also applies to the sections 13a adjacent to the inside of the clamping zones.
  • the tension clamps 1 and the busbars 3 are expediently corrugated in their interacting surface zones which act on the conductors.
  • the corrugation expediently extends over the inclined bottom walls 4 and the rounded taper tip 5.
  • the area of the flattening at the tapering tip at the end of the inclined surfaces 6 is formed as a fillet 7' pointing inwards with the same structure in the clamping zone. Together with the central axis rounding of the tapering tip 5 of the associated pull bow 1, this fillet 7 'forms a collecting and receiving space which is particularly suitable for collecting the multitude of individual wires in a particularly secure manner in the case of multi-stranded and fine-stranded conductors with a coarse nominal cross section centered, clearly defined position.
  • connection terminal types in which the conductive connection from terminal connection to terminal connection takes place via the clamping bodies themselves, which are conductively connected to one another, while on the underside, separate molded parts are provided as pressure pieces on the clamping screws.
  • the construction principle described above can also be realized with this type of connection terminal.
