Definitions

  • the invention relates to a connecting terminal for electrical conductors according to the preamble of claim 1.
  • Such connecting terminals with a centering terminal connection are known in various embodiments.
  • z. B. to DE-C- 923 562.
  • single-wire conductors of different cross-sections can be correctly set with appropriate centering, but this arrangement is unsuitable for clamping stranded or fine-stranded conductors, possibly even different conductors of different cross-sections. because there would be an undefined and uncontrolled cutting of the conductor wires on the inclined surfaces, with the result that some of the wires would then only be insufficiently clamped.
  • DE-U-16 01 608 in which, in addition, particularly small individual wires can no longer be reliably clamped because the pressure piece would touch the clamping body wall before they were clamped.
  • DE-C-1 16 294 shows a connecting terminal with which both single-wire and multi-wire conductors can be clamped.
  • inclined beads protruding inward are formed as centering in the central region of the clamping body, for which corresponding impressions which completely accommodate them are provided on the pressure piece.
  • Flawless clamping is only possible here in a relatively small nominal cross-sectional area of the conductors.
  • the clamping is now only carried out on the upper oblique edges of the beads, so that the clamping area is small and the wire is also subjected to a considerable bending force.
  • the beads In order to avoid this at least for the nominal cross-section suitable for the conductors, the beads must be arranged in such a way that a flat region of the bottom section remains between them.
  • a flat clamping body base interacts with a pressure piece that is flat on the underside. This is because there is no longer a central preferred position and, as is often the case, during laying work and the like. Pulled and pulled on the connected conductor, the clamped conductor end moves back and forth under copper abrasion in the clamping zone and loosening occurs very quickly.
  • the present invention is therefore based on the object of providing a connecting clamp of the generic type with which solid, multi-wire and fine-stranded conductors can be clamped properly in a large cross-sectional area.
  • the concave taper of the bottom of the sprag provides the desired centering option.
  • the projections provided on the pressure piece in the clamping zone and projecting beyond its tapering now also cause, with their bottom surfaces, in conjunction with their complete reception in the recesses in the walls of the clamping body base, that it cannot occur even with multi-stranded and fine-stranded conductors, that these are clamped in an undefined division in large areas of the oblique tapered surfaces. If the pressure piece for clamping moves towards the bottom area of the clamping body, the bottom-side surfaces of the side lugs push the conductor wires as far as possible from the oblique tapering surfaces onto the central longitudinal axis, i.e. the deepest zone of centering.
  • 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 pressure piece. Together with the oppositely curved tapering tip of the clamping body, this fillet forms one 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 takes place by means of a busbar 3, the two ends of which each lie in one of the tension clamps 1 and the ends of which thus form the pressure pieces which, by means of the clamping screws 2 placed on top of them, insert an inserted or stranded wire Fix the conductors or several inserted conductors with their undersides by clamping 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 tension bow central longitudinal axis, the intersection of which forms the tapering 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 corrugation extends over the central-axis flattening 7, the bottom surfaces 9 of the lugs 8 and the bottom surface of the sections 13.
  • 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 tension 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 of large nominal cross-section and compacting them 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.
