Zudem kann eine komplett unverlierbare Verrastung des Isolierkörpers 105 an einer geschwenkten Position gebildet sein. The plug-in portion 107 of the insulating body 105 dives correspondingly deep into the receptacle 109, so that it remains captive even in the high-rotated state. In addition, a completely captive locking of the insulating body 105 may be formed at a pivoted position.
Der Isolierkörper 105 umfasst ein leiterschonendes, bügeiförmiges Druckstück 1 15, das durch ein u-förmiges Stanzteil realisiert ist. Das Druckstück 1 15 ist an der Stirnfläche poliert, um beim Festziehen die Leiteradern zu schonen. Das Druckstück 1 15 ist in seitlich herausstehenden Druckstückaufnahmen 1 19 des nicht-drehbaren Isolierkörpers 105 unverlierbar verrastet ist. The insulating body 105 comprises a ladder-protecting, bow-shaped pressure piece 1 15, which is realized by a U-shaped stamped part. The pressure piece 1 15 is polished at the end face to protect when tightening the conductor wires. The pressure piece 1 15 is latched captive in laterally protruding pressure piece receptacles 1 19 of the non-rotatable insulating body 105.
Die diametral angeordneten Druckstückaufnahmen 1 19 für das Druckstück 1 15 sind mit herausstehenden Auslegerflügeln derart ausgestaltet, dass zusätzlich ein Berührschutz zu abgemantelten blanken Leitern gegeben ist. Die umgebogenen Endabschnitte des The diametrically arranged pressure piece receptacles 1 19 for the pressure piece 1 15 are designed with protruding boom wings such that in addition a Berührschutz is given to stripped bare conductors. The bent end sections of the
Druckstücks 1 15 sind mit einem Sägezahnprofil versehen, das Widerhaken bildet, so dass das Druckstücks 1 15 durch Eindrücken in die Druckstückaufnahme 1 19 des Isolierkörpers 105 befestigt werden kann. Weiter können die seitlich herausstehenden Druckstückaufnahmen 1 19 mit  Pressure piece 1 15 are provided with a sawtooth, which forms barbs, so that the pressure piece 1 15 can be fixed by pressing into the pressure piece receiving 1 19 of the insulator 105. Next, the laterally protruding pressure piece receptacles 1 19 with
Beschriftungsflächen versehen sein. Der Isolierkörper 105 kann farbig ausgeführt sein, beispielsweise um Phasen oder Spannungsebenen zu markieren. Alle diese Funktionalitäten können durch das Kunststoff teil des Isolierkörpers 105 gelöst werden. Fig. 2 zeigt eine schematische Ansicht einer weiteren Mantelklemme 100. Die Mantelklemme 100 umfasst ebenfalls einen u-förmigen Gewindebolzen 101 mit einem Schlitz 121 zum Einlegen eines Kabels und eine Hutmutter 103 zum Aufschrauben auf den Gewindebolzen 101 , um das Kabel zwischen dem Gewindebolzen 101 der Hutmutter 103 einzuklemmen und einen elektrischen Kontakt herzustellen.. Be provided labeling surfaces. The insulating body 105 may be colored, for example, to mark phases or voltage levels. All of these functionalities can be solved by the plastic part of the insulator 105. Fig. 2 shows a schematic view of another jacket clamp 100. The jacket clamp 100 also includes a U-shaped threaded bolt 101 with a slot 121 for inserting a cable and a cap nut 103 for screwing onto the threaded bolt 101 to the cable between the threaded bolt 101 of Clamp cap nut 103 and make an electrical contact.
Die Aufnahme 109 der Sockelplatte 1 1 1 und der Steckabschnitt 107 des Isolierkörpers 105 weisen eine im Querschnitt rechteckige Form auf, falls eine seitliche Schwenkbewegung anwendungstechnisch oder konstruktiv unerwünscht ist. Der Steckabschnitt 107 bildet eine Führungsscheibe, die gleichfalls das Heben und Senken des Isolierkörpers 105 in der Aufnahme 109 erlaubt. In der hochgeschraubten Position der Hutmutter 103 ist ein The receptacle 109 of the base plate 1 1 1 and the plug portion 107 of the insulator 105 have a rectangular in cross-section shape, if a lateral pivoting movement is application technology or constructive undesirable. The plug portion 107 forms a guide disc, which also allows the lifting and lowering of the insulating body 105 in the receptacle 109. In the raised position of the cap nut 103 is a
Wegklappen der Zylinderpartie des Isolierkörpers 105 zusammen mit der Hutmutter 103 möglich, so dass ein einfaches Einlegen der Leiter erreicht wird. Im oberen Teil des  Folding away the cylinder section of the insulating body 105 together with the cap nut 103 possible, so that a simple insertion of the ladder is achieved. In the upper part of the
Steckabschnittes 107 ist zu diesem Zweck ein Filmscharnier 1 13 vorgesehen, das das Wegklappen ermöglicht. Plug-in portion 107, a film hinge 1 13 is provided for this purpose, which allows the folding away.
Im Allgemeinen kann auch ein Isolierkörper 105 verwendet werden, der sowohl ein In general, an insulating body 105 may be used, which is both a
Wegklappen als auch ein seitliches Schwenken der Hutmutter 103 erlaubt. In diesem Fall kann ein dicker Rundstift als Steckabschnitt 107 vorgesehen sein, der im oberen Teil ein Filmscharnier aufweist, so dass die beiden Funktionsweisen des Klappens und Folding away as well as a lateral pivoting of the cap nut 103 allowed. In this case, a thick round pin can be provided as a plug-in portion 107, which has a film hinge in the upper part, so that the two functions of the flap and
Seitwärtsschwenkens realisiert werden können. Dadurch kann eine Zugänglichkeit zu den Leitern in dem u-förmigen Schlitz 121 des Gewindebolzens 101 verbessert werden. In einer weiteren Ausführungsform können zwei parallele Führungszapfen als Steckabschnitt 107 verwendet werden. Die Mantelklemme 100 ist in der Lage, außer ungeschnittenen Leitern auch mehrere Leiter unterschiedlichster Querschnitte und Drahtarten, wie beispielsweise massiv, mehrdrähtig, feindrähtig, mit oder ohne Aderendhülse, unmittelbar miteinander zu verklemmen. Die Mantelklemme 100 bildet eine anwendungstechnisch robust-sichere Lösung zum Verbinden von Leitern, ohne eine Handhabung beim Anschließen der Leiter zu beinträchtigen. Der Isolierkörper 105 ermöglicht eine Hoch/Runter-Bewegung der Hutmutter 103, ohne dass diese verloren gehen kann. Durch den Isolierkörper 105 ist die Hutmutter 103 beweglich und dennoch unverlierbar gelagert. Alle in Verbindung mit einzelnen Ausführungsformen der Erfindung erläuterten und gezeigten Merkmale können in unterschiedlicher Kombination in dem erfindungsgemäßen Gegenstand vorgesehen sein, um gleichzeitig deren vorteilhafte Wirkungen zu realisieren. Sideways pivoting can be realized. Thereby, accessibility to the conductors in the U-shaped slot 121 of the threaded bolt 101 can be improved. In a further embodiment, two parallel guide pins can be used as plug-in section 107. The jacket clamp 100 is capable, in addition to uncut conductors and several conductors of different cross-sections and types of wire, such as solid, stranded, fine stranded, with or without end sleeve to clamp directly to each other. The jacket clamp 100 forms an application-technically robust-safe solution for connecting conductors, without impairing handling when connecting the conductors. The insulator 105 allows up / down movement of the cap nut 103 without it being lost. By the insulating body 105, the cap nut 103 is movable and yet stored captive. All features explained and shown in connection with individual embodiments of the invention may be provided in different combinations in the article according to the invention, in order to simultaneously realize their advantageous effects.
