Description

Die Erfindung betrifft eine Batterieklemme, die einen metallischen Klemmenkörper in Form eines radialgeschlitzten Ringes, eine an den Ringenden angreifende Spannvorrichtung sowie eine Anschlußvorrichtung für einen mit der Klemme zu verbindenden elektrischen Leiter aufweist.The invention relates to a battery clamp, which has a metallic clamp body in the form of a radially slotted ring, a clamping device acting on the ring ends and a connecting device for an electrical conductor to be connected to the clamp.

Bei den bekannten Batterieklemmen dieser Art ist die Übertragung sehr hoher Ströme auch dann nicht problemlos, wenn die nur durch den radialen Schlitz unterbrochene Innenmantelfläche des Ringes, welche die Kontaktfläche des Klemmenkörpers bildet, möglichst genau auf den zu kontaktierenden, konischen Anschlußzapfen oder Pol der Batterie abgestimmt ist.In the known battery terminals of this type, the transmission of very high currents is not without problems even if the inner circumferential surface of the ring, which is only interrupted by the radial slot and forms the contact surface of the terminal body, is matched as precisely as possible to the conical connecting pin or pole of the battery to be contacted is.

Der Erfindung liegt die Aufgabe zugrunde, eine auch für sehr hohe Ströme geeignete Batterieklemme zu schaffen, die es ermöglicht, mit geringem Aufwand eine hohe und sich auch über lange Zeiträume hinweg nicht oder zumindest nicht wesentlich verschlechternde Kontaktqualität zu gewährleisten.The invention has for its object to provide a battery terminal which is also suitable for very high currents and which makes it possible, with little effort, to ensure a high contact quality which does not deteriorate, or at least not significantly deteriorates, even over long periods of time.

Diese Aufgabe ist mit den Merkmalen des Anspruches 1 gelöst. Die an der Ringinnenseite vorgesehenen Zähne garantieren eine gleichmäßige Anlage an der Mantelfläche des Batteriepols, wodurch ein optimaler Kontakt zwischen dem Klemmenkörper und den: Batteriepol erreicht wird, was Voraussetzung ist für die Erzielung einer maximalen Strombelastbarkeit der Batterieklemme.This object is achieved with the features of claim 1. The teeth provided on the inside of the ring guarantee a uniform contact with the outer surface of the battery pole, which ensures optimal contact between the terminal body and the battery pole, which is a prerequisite for achieving maximum current carrying capacity of the battery terminal.

Damit auch noch bei sehr großen Fertigungstoleranzen des Batteriepols oder der Batterieklemme eine gleichmäßige Anlage der Kopfflächen der Zähne am Batteriepol gewährleistet ist, sind bei einer bevorzugten Ausführungsform die im Bereich zwischen dem radialen Schlitz und der ihm gegenüberliegenden Stelle angeordneten Zähne gegenüber der radialen Richtung in Umfangsrichtung des Ringes gegen die dem radialen Schlitz gegenüberliegende Stelle hin geneigt. Hierdurch erreicht man eine gewisse Federung der Zähne, die zum Ausgleich großer Toleranzen ausreicht. Außerdem trägt die federnde Vorspannung der Zähne bei montierter Batterieklemme dazu bei, negative Einflüsse auf die Kontaktqualität durch Wärmedehnung zu unterdrücken.So that even with very large manufacturing tolerances of the battery pole or the battery clamp, a uniform contact of the head surfaces of the teeth on the battery pole is ensured, in a preferred embodiment, the teeth arranged in the area between the radial slot and the opposite location are opposite the radial direction in the circumferential direction of the Ring inclined towards the point opposite the radial slot. This results in a certain amount of tooth suspension, which is sufficient to compensate for large tolerances. In addition, the resilient pre-tensioning of the teeth when the battery clamp is installed helps to suppress negative influences on the contact quality through thermal expansion.

Um eine gleichmäßige Biegebeanspruchung des Ringes sicherzustellen, was im Hinblick auf eine gleichmäßige Anlage der Zähne am Batteriepol ebenfalls vorteilhaft ist, ist vorzugsweise der Querschnitt des die Zähne tragenden, ringförmigen Teils des Klemmenkörpers im Bereich des Grundes der zwischen den Zähnen vorhandenen Nuten rechteckförmig. Dieser rechteckförmige Querschnitt führt außerdem zu Nuten, deren Längsachse parallel zur Längsachse des vom ringförmigen Teil des Klemmenkörpers gebildeten Kanals verläuft, was für die Herstellung der Batterieklemme aus einem Ziehprofil, aber auch für ein Herausarbeiten der Nuten aus einem ringförmigen Körper,von großem Vorteil ist.In order to ensure a uniform bending stress of the ring, which is also advantageous with regard to a uniform abutment of the teeth on the battery pole, the cross section of the annular part of the clamp body that supports the teeth is preferably rectangular in the region of the base of the grooves present between the teeth. This rectangular cross section also leads to grooves, the longitudinal axis of which runs parallel to the longitudinal axis of the channel formed by the annular part of the clamp body, which is useful for producing the battery clamp from a drawn profile, but also for working out the grooves from an annular one Body, is of great advantage.

Um den Materialaufwand und die mit der Spannvorrichtung aufzubringende Spannkraft sowie den Raumbedarf der erfindungsgemäßen Klemme so gering wie möglich zu halten, nimmt der Querschnitt des den Ring bildenden Teils des Klemmenkörpers einer besonders vorteilhaften Ausführungsform von den Ringenden gegen die dem radialen Schlitz gegenüberliegende Stelle hin ab. Besonders vorteilhaft ist es hierbei, wenn der Querschnitt des Ringes eine Größe hat, die eine wenigstens annähernd gleiche Biegebeanspruchung ergibt.In order to keep the cost of materials and the clamping force to be applied with the clamping device as well as the space requirement of the clamp according to the invention as low as possible, the cross section of the part of the clamp body forming the ring of a particularly advantageous embodiment decreases from the ring ends towards the point opposite the radial slot. It is particularly advantageous here if the cross section of the ring has a size that results in an at least approximately the same bending stress.

Für eine hohe und über lange Zeiträume hinweg zumindest annähernd gleichbleibende Kontaktqualität ist auch die Ausbildung der Anschlußvorrichtung für den elektrischen Leiter von großer Bedeutung. Bei einer bevorzugten Ausführungsform ist deshalb die Anschlußvorrichtung als eine Preßhülse mit in Umfangsrichtung variierender Wandstärke ausgebildet. Eine Preßhülse ist in mancherlei Hinsicht gegenüber anders ausgebildeten Anschlußvorrichtungen vorteilhaft. Erwähnt sei hierbei beispielhaft nur die Brauchbarkeit auch für Aluminiumkabel und der erzielbare hohe Kontaktdruck. Eine optimale Kontaktqualität erhält man mit einfachen Mitteln jedoch erst durch die variable Wandstärke der Preßhülse, weil hierdurch beim Verpressen eine unterschiedlich starke radiale Druckbeanspruchung des Leiters erreicht wird, was bei Seilen, und zwar auch bei sehr feindrähtigen Seilen und solchen aus Aluminium, zu einer optimalen Kontaktierung des Seiles und einer optimalen, eine hervorragende Querleitfähigkeit ergebenden Verdichtung des Seiles führt.For a high and at least approximately constant contact quality over long periods of time, the design of the connection device for the electrical conductor is also of great importance. In a preferred embodiment, the connection device is therefore designed as a compression sleeve with a wall thickness that varies in the circumferential direction. A press sleeve is advantageous in many respects compared to differently designed connection devices. Only the usability for aluminum cables and the high contact pressure that can be achieved are mentioned here as examples. Optimal contact quality can only be obtained with simple means through the variable wall thickness of the compression sleeve, because this results in a different radial pressure load on the conductor during crimping, which leads to an optimum with ropes, even with very fine-stranded ropes and those made from aluminum Contacting the rope and an optimal compression of the rope resulting in an excellent transverse conductivity.

Hinsichtlich des Fertigungs- und Montageaufwandes besonders vorteilhaft ist eine Form der Preßhülse gemäß Anspruch 6, weil eine kreiszylindrische Längsbohrung der Preßhülse fertigungstechnisch besonders günstig ist und die Verpressung mittels eines einen kreiszylindrischen Preßkanal aufweisenden Preßwerkzeuges erfolgen kann. Da mit zunehmender Anzahl der Ecken des die äußere Kontur der Preßhülse bildenden Polygons die Unterschiede in der radialen Verpressung geringer werden, ist es zweckmäßig, die Eckenzahl nicht größer als acht zu wählen.A form of the compression sleeve according to claim 6 is particularly advantageous with regard to the manufacturing and assembly effort, because a circular cylindrical longitudinal bore of the compression sleeve is particularly favorable in terms of production technology and the pressing can be carried out by means of a compression tool having a circular cylindrical compression channel. As the number of corners of the polygon forming the outer contour of the compression sleeve increases, the differences in the radial compression become smaller, it is advisable not to choose more than eight corners.

Einen dichten Verschluß der Preßhülse, der eine Beeinträchtigung der Kontaktqualität zwischen der Preßhülse und dem Leiter durch äußere Störeinflüsse verhindert, läßt sich in besonders einfacher Weise erreichen, wenn die Preßhülse gemäß Anspruch 9 ausgebildet ist, da dann beim Verpressen der im Inneren der Preßhülse liegende Endabschnitt der Kabelisolation eine Dichtung bildet.A tight closure of the press sleeve, which prevents the contact quality between the press sleeve and the conductor from being impaired by external interference, can be achieved in a particularly simple manner if the press sleeve is designed according to claim 9, since then the end section lying inside the press sleeve is pressed the cable insulation forms a seal.

Sowohl im Hinblick auf den Widerstand, den die Klemme für den zu übertragenden Strom bildet, als auch aus Raum- und Fertigungsgründen ist bei einer bevorzugten Ausführungsform der erfindungsgemäßen Klemme, die sich an die Ringenden anschliessende Flansche aufweist, die mit je einer Durchgangsbohrung zur Aufnahme einer Spannschraube versehen sind, die Preßhülse mit an den einen Flansch gleichachsig/dessen Durchgangsbohrung angeformt, wobei im Anschluß an den der Aufnahme des Leiterendes dienenden Abschnitt der Hülsenlängsbohrung der Kopf der Spannschraube liegt. Beim Verpressen der Preßhülse im Bereich des Kopfes dieser Schraube wird die Schraube gegen ein Verdrehen gesichert. Außerdem wird die Preßhülse mit Hilfe des Schraubenkopfes auch an diesem Ende dicht verschlossen.Both in terms of the resistance that the terminal forms for the current to be transmitted, and for space and manufacturing reasons, in a preferred embodiment of the terminal according to the invention, which has flanges adjoining the ring ends, each with a through hole for receiving a Tensioning screw are provided, the compression sleeve is formed with a flange coaxial with its through hole, the head of the tensioning screw being located after the section of the sleeve longitudinal bore serving to accommodate the conductor end. When pressing the compression sleeve in the area of the head of this screw, the screw is secured against twisting. In addition, the compression sleeve is also sealed at this end with the help of the screw head.

Bei einer bevorzugten Ausführungsform sind der Klemmenkörper und die Preßhülse durch ein von einem Profilstab abgelängtes Stück gebildet. Hierdurch wird der Fertigungsaufwand minimiert. Außerdem ist die rechteckförmige oder quadratische äußere Kontur der Preßhülse, die sich beim Ablängen von einem Profilstab ergibt, für eine in Umfangsrichtung des Leiters unterschiedliche radiale Verpressung beim Rundpressen der Preßhülse besonders vorteilhaft. Das Rundpressen der Preßhülse beim Verpressen ist auch insofern vorteilhaft, als das hierzu erforderliche Preßwerkzeug besonders einfach ausgebildet ist und in beliebiger Winkellage an die Preßhülse angesetzt werden kann.In a preferred embodiment of the clamp body and the compression sleeve are abgelän by one from a section bar formed g th piece. This minimizes the manufacturing effort. In addition, the rectangular or square outer contour of the compression sleeve, which results when a profile bar is cut to length, is particularly advantageous for a radial compression which differs in the circumferential direction of the conductor when the compression sleeve is pressed round. The round pressing of the pressing sleeve during pressing is also advantageous in that the pressing tool required for this is particularly simple and can be attached to the pressing sleeve in any angular position.

Im folgenden ist die Erfindung anhand eines in der Zeichnung dargestellten Ausführungsbeispiels im einzelnen erläutert. Es zeigen:

  • Fig. 1 das Ausführungsbeispiel teils in Ansicht und teils im Längsschnitt,
  • Fig. 2 einen Schnitt nach der Linie II - II der Fig. 1,
  • Fig. 3 einen schematisch dargestellten Schnitt entsprechend Fig. 2 nach dem Verpressen.
The invention is explained in detail below using an exemplary embodiment shown in the drawing. Show it:
  • 1 shows the embodiment partly in view and partly in longitudinal section,
  • 2 shows a section along the line II - II of FIG. 1,
  • Fig. 3 shows a schematically illustrated section corresponding to Fig. 2 after pressing.

Eine Batterieanschlußklemme zur Herstellung einer für hohe Ströme geeigneten Verbindung zwischen einem Aluminiumkabel 1 und dem durch einen nicht dargestellten, konischen Bolzen gebildeten Pol einer Batterie weist einen Klemmenkörper 2 in Form eines radial geschlitzten Ringes auf. An das eine Ringende ist ein Flansch 3, an das andere Ringende ein zu ihm parallel liegender Flansch 4 angeformt, zwischen denen sich der radiale Schlitz des Klemmenkörpers 2 nach außen hin fortsetzt. Eine Durchgangsbohrung 5 des Flansches 3 steht mit ihrer Längsachse lotrecht auf der durch das Zentrum des vom Klemmenkörper 2 gebildeten Klemmkanals 6 gehenden, radial verlaufenden Mittelebene des den Klemmenkörper 2 teilenden Schlitzes 7.A battery connection terminal for establishing a connection suitable for high currents between an aluminum cable 1 and the pole of a battery formed by a conical bolt (not shown) has a terminal body 2 in the form of a radially slotted ring. A flange 3 is formed on one ring end, and a flange 4 lying parallel to it is formed on the other ring end, between which the radial slot of the clamp body 2 continues outwards. A through hole 5 of the flange 3 is perpendicular with its longitudinal axis on the radially extending central plane of the slot 7 dividing the clamp body 2 and passing through the center of the clamp channel 6 formed by the clamp body 2.

Der andere Flansch 4, der mit einer mit der Durchgangsbohrung 5 fluchtenden Durchgangsbohrung 8 versehen ist, ist auf der dem Flansch 3 abgekehrten Seite einstückig mit einer Preßhülse 9 ausgebildet, deren Längsachserit der Längsachse der Durchgangsbohrung 8 fluchtet.The other flange 4, which is provided with a through hole 8 aligned with the through hole 5, is formed in one piece on the side facing away from the flange 3 with a compression sleeve 9, the longitudinal axis of which is aligned with the longitudinal axis of the through hole 8.

Wegen der einstückigen Ausbildung der Preßhülse 9 mit dem Klemmenkörper 2 ist das Material, aus dem diese beiden Teile bestehen, ein verpreßbares Aluminium. Um die erfindungsgemäße Klemme möglichst kostengünstig herstellen zu können, werden der Klemmenkörper 2 und die Preßhülse 9 von einem Ziehprofil abgelängt. Die Preßhülse 9 hat deshalb im unverpreßten Zustand eine rechteckige Außenkontur, wieBecause of the one-piece design of the compression sleeve 9 with the clamp body 2, the material from which these two parts are made is a compressible aluminum. In order to be able to produce the clamp according to the invention as inexpensively as possible, the clamp body 2 and the compression sleeve 9 are cut to length from a drawing profile. The compression sleeve 9 therefore has a rectangular outer contour in the uncompressed state, such as

Fig. 2 zeigt. Sie besteht aus einer Aluminiumlegierung, die wesentlich härter ist als das Aluminium, aus dem die feindrähtige Seele 11 besteht.Fig. 2 shows. It consists of an aluminum alloy that is much harder than the aluminum from which the finely stranded core 11 is made.

Der Innendurchmesser der Längsbohrung 10 der Preßhülse 9 ist mit Ausnahme eines Abschnittes am freien Ende der Preßhülse 9 auf den Außendurchmesser der als Seil ausgebildeten Seele 11 des Aluminiumkabels 1 angepaßt. Im Bereich des vorstehend erwähnten Abschnittes ist der Innendurchmesser der Längsbohrung 10 auf den Außendurchmesser der Isolation 12 des Aluminumkabels 1 abgestimmt. Es ist dann gewährleistet, daß bei einem Rundverpressen, bei dem die Preßhülse eine im wesentlichen kreiszylindrische Außenmantelfläche erhält, wie Fig. 3 zeigt, der Preßhülse im Bereich der schematisch angedeuteten Preßstellen 13 nicht nur eine optimale Kontaktbildung mit der Seele 11 einschließlich einer optimalen Komprimierung dieser Seele dank der ungleichmäßigen radialen Verpressung erreicht wird, sondern auch ein völlig dichter Verschluß in dem die Isolation 12 aufnehmenden Endabschnitt. Von diesem freien Ende der Preßhülse 9 her können also keine Feuchtigkeit oder andere äußere Störeinflüsse in das Innere der Preßhülse und zu dem abisolierten Endabschnitt der Seele 11 gelangen.With the exception of a section at the free end of the compression sleeve 9, the inside diameter of the longitudinal bore 10 of the compression sleeve 9 is adapted to the outside diameter of the core 11 of the aluminum cable 1 which is designed as a rope. In the area of the above-mentioned section, the inside diameter of the longitudinal bore 10 is matched to the outside diameter of the insulation 12 of the aluminum cable 1. It is then ensured that in a round pressing, in which the compression sleeve receives a substantially circular cylindrical outer surface, as shown in FIG. 3, the compression sleeve in the area of the schematically indicated pressing points 13 not only an optimal contact formation with the soul 11 including an optimal compression of this Soul is achieved thanks to the uneven radial compression, but also a completely tight seal in the end portion receiving the insulation 12. From this free end of the compression sleeve 9, no moisture or other external interference can get into the interior of the compression sleeve and to the stripped end section of the core 11.

In dem sich unmittelbar an den Flansch 4 anschließenden Abschnitt der Preßhülse 9 liegt der Kopf 14 einer im Ausführungsbeispiel aus rostfreiem Stahl bestehenden Spannschraube 15, welche die beiden Durchgangsbohrungen 5 und 8 der Flansche 4 bzw. 3 durchdringt. Da die Preßhülse 9 auch in dem den Kopf 14 umgebenden Bereich so verpreßt wird, daß ein dichter Verschluß entsteht, können auch durch die Durchgangsbohrungen 8 hindurch keine Feuchtigkeit oder andere Störeinflüsse in das Innere der Preßhülse 9 gelangen. Kontaktfett, das vor dem Verpressen in die Preßhülse 9 eingefüllt wird, verhindert Lufteinschlüsse im Inneren der Preßhülse 9.In the section of the compression sleeve 9 directly adjoining the flange 4, there is the head 14 of a clamping screw 15, which in the exemplary embodiment is made of stainless steel, and which penetrates the two through bores 5 and 8 of the flanges 4 and 3, respectively. Since the compression sleeve 9 is pressed in the area surrounding the head 14 in such a way that a tight seal is formed, no moisture or other interferences can get into the interior of the compression sleeve 9 through the through holes 8. Contact grease, which is filled into the compression sleeve 9 before pressing, prevents air pockets in the interior of the compression sleeve 9.

Durch die Verpressung der Preßhülse 9 im Bereich des Kopfes 14, der im Ausführungsbeispiel ein Vierkantkopf ist, aber auch ein Sechskantkopf sein könnte, kann sich die Spannschraube 15 nicht relativ zur Preßhülse 9 und den Flanschen 4 sowie 3 verdrehen. Eine an der dem Flansch 4 abgekehrten Seite des Flansches 3 anliegende Mutter 16 kann deshalb angezogen werden, ohne dabei die Spannschraube 15 mittels eines Werkzeuges gegen ein Verdrehen sichern zu müssen.By pressing the compression sleeve 9 in the area of the head 14, which in the exemplary embodiment is a square head, but could also be a hexagonal head, the clamping screw 15 cannot rotate relative to the compression sleeve 9 and the flanges 4 and 3. A nut 16 resting on the side of the flange 3 facing away from the flange 4 can therefore be tightened without having to secure the clamping screw 15 against rotation by means of a tool.

Das Zentrum des vom Klemmenkörper 2 gebildeten Klemmkanals 6 ist, wie Fig. 1 zeigt, aus dem Zentrum der zylindrischen Außenmantelfläche des Klemmenkörpers 2 heraus gegen die dem Schlitz 7 gegenüberliegende Stelle des Klemmenkörpers 2 hin versetzt. Dadurch nimmt der Querschnitt des ringförmigen Teils des Klemmenkörpers 2 von den die Flansche 3 bzw. 4 tragenden Enden aus gegen die dem Schlitz 7 gegenüberliegende Stelle hin ab, und zwar derart, daß bei einem Zusammenspannen der beiden Flansche e-ine annähernd gleiche Biegebeanspruchung des ringförmigen Teils des Klemmenkörpers errecht wird.As shown in FIG. 1, the center of the clamping channel 6 formed by the clamp body 2 is offset from the center of the cylindrical outer surface of the clamp body 2 towards the point of the clamp body 2 opposite the slot 7. As a result, the cross section of the annular part of the clamp body 2 decreases from the ends carrying the flanges 3 and 4 towards the point opposite the slot 7, in such a way that when the two flanges are clamped together, approximately the same bending stress is applied to the annular one Part of the clamp body is achieved.

Den Klemmkanal 6 begrenzen Zähne 17, zwischen denen je eine Nut 18 liegt. Im Ausführungsbeispiel sind neun Zähne vorgesehen. Die Kopffläche 17' jedes dieser Zähne 17, welche die Kontaktfläche des Zahnes bildet, liegt in der gemeinsamen konischen Fläche, welche an die konische Außenmantelfläche des Poles der Batterie angepaßt ist. Hingegen verläuft die Längsachse aller Nuten 18 parallel zur Längsachse des Klemmkanals 6. Der Querschnitt des ringförmigen Teils des Klemmenkörpers 2 ist deshalb im Bereich des Nutgrundes jeder Nut 18 ein Rechteck, was zu einer gleichen Biegespannung über die gesamte axiale Länge des Klemmenkörpers 2 führt. Außerdem können infolge dieser Lage der Nutlängsachse die Nuten 18 am Ziehprofil vorgesehen sein, was insofern vorteilhaft-ist, als dann das Einarbeiten der Nuten 18 entfällt. Aber auch dann, wenn die Nuten 18 nachiträglich eingearbeitet werden müssen, ist eine zur Längsachse des Klemmkanals 6 parallele Lage vorteilhaft.The clamping channel 6 delimit teeth 17, between each of which there is a groove 18. In the exemplary embodiment, nine teeth are provided. The top surface 17 'of each of these teeth 17, which forms the contact surface of the tooth, lies in the common conical surface which is adapted to the conical outer surface of the pole of the battery. On the other hand, the longitudinal axis of all grooves 18 runs parallel to the longitudinal axis of the clamping channel 6. The cross section of the annular part of the clamp body 2 is therefore a rectangle in the region of the groove base of each groove 18, which leads to the same bending stress over the entire axial length of the clamp body 2. In addition, as a result of this position of the longitudinal axis of the groove, the grooves 18 can be provided on the drawing profile, which is advantageous in that the grooves 18 are then not incorporated. But even if the grooves 18 have to be worked in later, a position parallel to the longitudinal axis of the clamping channel 6 is advantageous.

Wie Fig. 1 zeigt, sind alle Zähne mit Ausnahme desjenigen, welcher an der dem Schlitz 7 gegenüberliegenden Stelle vorgesehen ist, in Umfangsrichtung gegen diese Stelle hin gegenüber der radialen Richtung geneigt, was eine gleichmäßige Anlage aller Kopfflächen 17' am Pol der Batterie fördert, weil so die Zähne 17 besser Toleranzen ausgleichen können. Wie die Figur zeigt, sind alle Nuten 18 mit Ausnahme der beiden neben dem mittleren Zahn liegenden Nuten parallelflankig ausgebildet.As shown in FIG. 1, all the teeth, with the exception of that which is provided at the point opposite the slot 7, are inclined in the circumferential direction towards this point with respect to the radial direction, which promotes an even contact of all the head surfaces 17 ′ on the battery pole, because the teeth 17 can better compensate for tolerances. As the figure shows, all the grooves 18, with the exception of the two grooves lying next to the central tooth, are formed with parallel flanks.

Sofern die Nuten 18 bereits im Ziehprofil vorhanden sind, müssen nach dem Ablängen des Klemmenkörpers 2 und der Preßhülse 9 vom Ziehprofil nur dem Klemmkanal 6 seine konische Form gegeben sowie die beiden Flansche 3 und 4 und die Preßhülse 9 durchbohrt werden. Der Fertigungsaufwand ist deshalb relativ gering.If the grooves 18 are already present in the drawing profile, only the clamping channel 6 must be given its conical shape after the clamping body 2 and the compression sleeve 9 have been cut to length from the drawing profile, and the two flanges 3 and 4 and the compression sleeve 9 have to be drilled through. The manufacturing effort is therefore relatively low.
