Definitions

  • the invention relates to a terminal for connecting an electrical line to an electrical rail, the terminal having a terminal body designed as a one-piece frame for receiving the line and rail on top of one another in a passage enclosed by the frame, as well as a one-piece clamping screw, the clamping screw having a threaded section and a Comprising pressure body portion, the frame also having a threaded bore through which the threaded portion of the clamping screw penetrates, and the electrical line and the electrical rail can be tensioned against the frame by means of the adjustable clamping screw via its pressure body portion.
  • Such terminals are designed in particular as device or direct connection terminals in electrical switchgear or electrical devices, such as for busbars, fuse strips and fuse switch strips.
  • the frame surrounds a clamping or clamping space which is essentially closed on four sides and which is open on two opposite sides.
  • the electrical line and the electrical Rail inserted and tensioned against the frame by means of the tensioning screw.
  • the electrical cable and the electrical rail are introduced as a rule from opposite sides of the clamping or clamping space.
  • the electrical lines can be designed in different ways, for example as a single-wire cable that extends over a circular sector of 90 ° or 120 °.
  • the arrangement of four cables, which extend over a circular angle of 90 ° each, enables the arrangement of an overall cable which extends over a full circle.
  • a full circle arrangement is possible with an arrangement of three cables, each extending over an angle of 120 °.
  • the cables can be designed as single-wire or multi-wire.
  • the cables are formed in particular from copper or aluminum, which also includes alloys on this basis.
  • the rail used in each case is designed in particular as a tab.
  • the rail is preferably made of copper or a copper alloy.
  • a clamp of the type mentioned which thus has the features of the preamble of claim 1, is from DE 76 17 897 U known.
  • the pressure body section of the tensioning screw is hemispherical, the diameter of the ball corresponding to the diameter of the threaded section of the tensioning screw.
  • the clamping screw In relation to the dimensions of the passage enclosed by the frame, the clamping screw has such a large axial length that it cannot be mounted from the passage, and thus can be screwed into the threaded hole in the frame. This is only possible from the side of the frame facing away from the passage.
  • the hemispherical design of the pressure body section has the disadvantage that the pressure body section only acts on the electrical line in its central, small front section when the clamping screw is adjusted, and as a result of this it is necessary to apply very high clamping forces there in order to connect the electrical line to the electrical rail to clamp. Since the pressure body portion is hemispherical, and the ball diameter corresponds to the outer diameter of the threaded portion of the Corresponding to the clamping screw, it is also necessary in this clamp to make the passage enclosed by the frame adjacent to the threaded hole with a reduced cross-section, in order to prevent the cable's lateral areas from being undesirably pressed on both sides when the cable is clamped. A profiling of the passage is accordingly provided with an enlarged passage area at the point where the rail is arranged with respect to the clamp.
  • Terminals for connecting an electrical line to an electrical rail are known in which the clamping screw is designed in several parts, thus in particular has a threaded section representing one component and a pressure body section representing another component.
  • the tensioning screw is designed in two parts
  • the pressure body section can be designed in any desired shape due to the two-part design, in particular under the aspect of optimal transmission of the tensioning force from the tensioning screw to the electrical line.
  • such a clamp is associated with increased construction and assembly costs, since on the one hand two components have to be produced with regard to the clamping screw and these also have to be assembled.
  • Such a two-part tensioning screw cannot be mounted from the passage of the frame either.
  • the threaded section is usually screwed into the threaded hole in the frame until the threaded section of the clamping screw protrudes into the passage enclosed by the frame and the pressure body section is then connected to the threaded section.
  • DE 21 38 715 A1 describes an electrical connection socket in which a screw freely traverses a lateral opening made in a wall of the socket and interacts with a nut which is arranged outside the socket.
  • the screw has a circular washer at its operative end located in the socket, this operative end serving to retain a cable located in the socket in the socket by the operative end of the screw with the cable against an inner surface of the socket presses.
  • the circular washer can be attached to the screw or is integral therewith.
  • a clamp which has the features of the preamble of claim 1.
  • the pressure body section of the one-piece tensioning screw based on an axis of rotation of the tensioning screw, has a greater extent perpendicular to the axis of rotation than the diameter of the threaded hole in the frame.
  • the frame has walls surrounding the passage, one of the walls having a threaded hole for the clamping screw and a wall opposite this wall, which forms a clamping surface, has a through opening for the clamping screw. This through opening is of sufficient size to allow the clamping screw to pass through.
  • the screw is inserted into the frame in such a way that the clamping screw is inserted from the outside along an axis of the threaded section into the passage enclosed by the frame, the clamping screw being guided through the through opening for the purpose of inserting the clamping screw into the passage.
  • the object of the present invention is to develop a clamp of the type mentioned at the outset in such a way that it can be produced simply and inexpensively and can be easily installed, and furthermore has an optimal permanent functionality.
  • the pressure body section based on an axis of rotation of the clamping screw, has a greater extent perpendicular to the axis of rotation than the diameter of the threaded hole in the frame, and the passage of the frame is dimensioned such that the clamping screw from the passage can be screwed into the threaded hole and completely screwed out of the threaded hole into the passage.
  • the clamping screw also has, in a projection in the direction of insertion of the line and rail into the passage of the frame, such a cross-sectional shape that it envelops by a cross-sectional shape of the passage, seen in a direction of extension of the line and rail in the direction of the passage of the frame becomes.
  • the clamp according to the invention thus combines the advantages of the one-piece clamping screw, which is easy to manufacture and, due to the one-piece nature, does not require separate assembly to form the clamping screw, with the advantages of optimal clamping of the electrical line and electrical rail due to the fact that the pressure body section of the clamping screw, in relation to the axis of rotation of the clamping screw, has a greater extent perpendicular to the axis of rotation than the diameter of the threaded hole in the frame.
  • the one-piece design of the clamping screw combined with the greater extent of the pressure body section than the diameter of the threaded hole, perpendicular to the axis of rotation of the clamping screw, ensures optimal long-term functionality.
  • parts of the clamping screw cannot change from one another, since the clamping screw is designed in one piece and, moreover, the clamping connection is significantly more secure because the pressure body section of the clamping screw covers a large surface section the electric line acts. With a relatively high tensioning force of the tensioning screw, there is thus a relatively large deformation of the electrical line.
  • the frame consists of aluminum or an aluminum alloy and / or the clamping screw consists of aluminum or an aluminum alloy.
  • a clamp can be made that is relatively light in weight with high strength.
  • a contact grease is preferably used in the critical electrical contact areas to ensure oxygen tightness.
  • a contact grease between the clamping screw and the electrical line also reduces the friction between these components when the clamping force is applied via the clamping screw.
  • the threaded section of the clamping screw and / or the threaded hole of the frame is preferably also greased in order to minimize the thread friction in order to achieve the highest possible clamping force.
  • the threaded section of the clamping screw preferably has a fine thread.
  • a fine thread makes it possible to apply very high forces via the tensioning screw for tensioning the electrical line and electrical rail between the tensioning screw and the frame, whereby it is not necessary to apply particularly high adjusting forces for turning the tensioning screw.
  • the fine thread has a pitch which is 40% to 60%, in particular 50% of a standard thread according to DIN 13-1: 1999-11.
  • the clamping screw preferably has a fine thread M16 with a pitch of 1 mm.
  • the tensioning screw for tensioning the electrical line and the electrical rail between the tensioning screw and the frame can be actuated particularly easily if the tensioning screw is in the area of the pressure body section has a receptacle for a tool for turning the clamping screw at the opposite end.
  • the receptacle is preferably designed as a hexagon socket recess.
  • the frame is preferably designed in such a way that it has a head section which has the threaded bore, a bottom section arranged opposite the head section, and side sections connecting the head section and the bottom section.
  • the side sections are preferably arranged parallel to one another. This ensures that the cross section of the passage, viewed perpendicular to the axis of rotation of the clamping screw, does not change in the longitudinal extension of the side sections, thus in the extension of the side sections in the direction of the axis of rotation of the clamping screw. This is advantageous when tensioning for the purpose of connecting the electrical line to the electrical rail.
  • the head section is arranged perpendicular to the side sections. This arrangement of the head section is advantageous from the point of view of a simple geometry of the passage, the passage having a constant cross section, in particular over a large length section, based on the longitudinal extension of the axis of rotation of the clamping screw.
  • the bottom section is V-shaped, in particular a central area of the bottom section facing away from the side section has a smaller V angle than outer areas of the bottom section adjoining this area of the bottom section towards the side sections.
  • the V-shaped design of the bottom section enables an optimal positioning of an electrical rail, which is also V-shaped in cross section, this rail in particular having the same V angle as the bottom section. If, according to a further development, the central area of the floor section has a smaller V-angle than the outer areas of the floor section adjoining this central area, the terminal is different, in particular for connecting electrical rails Have V angles, suitable.
  • connection of an electrical rail with a V-angle which corresponds to the V-angle of the central area, or the connection of an electrical rail with a V-angle, which corresponds to the V-angle that the outer areas enclose with one another, is particularly suitable. corresponds.
  • the central area of the floor section includes a V angle of approximately 85 ° to 95 °, in particular 90 °, and / or the outer areas of the floor section form a V angle of approximately 115 ° to 125 °, in particular 120 ° lock in.
  • this central area is preferably used to accommodate an electrical rail with a V-angle of 90 °, this V-rail in turn making contact with an electrical line, which is described in particular in Art of a cable is formed with a circular sector angle of 90 °. In this 90 ° sector area of the electrical line, it makes contact with the electrical rail.
  • the bottom section has a corrugation on its side facing the passage.
  • the bottom section makes contact with the electrical rail via this corrugation. If the tensioning screw is adjusted, the tensioning screw with its pressure body section presses on the electrical line and this on the electrical rail, the electrical rail being tensioned against the frame in the area of the base section and the frame in the area of the corrugation via micro-deformations generated by the corrugation the rail penetrates. This leads to a significant improvement in the electrical conductivity of the terminal.
  • inner surfaces of the side sections facing the passage and arranged parallel to one another are arranged perpendicular to an inner surface of the head section facing the passage.
  • the threaded hole extends in particular over the entire thickness of the head section. Because of this relatively large thread length of the threaded hole, very high clamping forces can be transmitted between the frame and the clamping screw.
  • the pressure body section of the tensioning screw too, it is considered to be advantageous if it has a specially adapted geometry with regard to the electrical line on which the pressure body section acts in particular.
  • the pressure body section of the clamping screw is designed to taper conically in the direction of the base section. This makes it possible, on the one hand, to apply high pressure to the electrical line when the clamping screw is infeed and, on the other hand, to ensure a defined deformation behavior of the electrical line when the pressure body section acts.
  • first flank sections of the cone enclose an angle of 115 ° to 125 °, in particular an angle of 120 °, and / or second flank sections of the cone enclose an angle of 85 ° to 95 °, in particular an angle of Include 90 ° with each other.
  • a central region between the first flank sections or the second flank sections has a bulge protruding in the direction of the bottom section. This curvature ensures optimal initial clamping of the electrical line, with subsequent optimal deformation of the electrical line, which acts on the electrical rail and thus tensions it against the frame.
  • the pressure body section has an outer ring section which is arranged rotationally symmetrical to the axis of rotation of the tensioning screw and which projects radially outward beyond the conically tapered area of the pressure body section, in particular the outer diameter of the outer ring section is slightly smaller than the distance between the side sections of the frame in the area of the outer ring section.
  • the pressure body section is designed to be rotationally symmetrical to the axis of rotation of the clamping screw.
  • this is advantageous in terms of the torques to be applied when clamping.
  • the clamping screw can simply be produced as a turned part which is to be provided with the threaded section and the receptacle for the tool.
  • the frame is designed as an extruded profile is particularly advantageous.
  • This extruded profile is provided with the threaded hole.
  • Such a frame can be produced in a particularly simple manner in that, as an essential production step, the extruded profile is to be cut perpendicular to its extrusion direction. With such a design as an extruded profile, the corrugations in the frame can easily be produced directly. In particular, a single-layer surrounding frame is thus provided. This design is thus compared to the design of the frame from a one-piece plate with overlapping ends, as in FIG DE 10 2014 011 558 A1 described as particularly advantageous.
  • the aim is to ensure that the geometry of the tensioning screw and frame are matched to one another in such a way that the tensioning screw can be installed with a minimal amount of space not required for installing the tensioning screw.
  • the clamping screw in the projection in the direction of insertion of the line and rail into the passage of the frame, has such a cross-sectional shape that it differs from the cross-sectional shape of the passage in the direction of extension of the line and rail in The direction of passage of the frame is seen slightly enveloped.
