NH-SicherungsleisteNH fuse strip
Die Neuerung betrifft eine NH-Sicherungsleiste gemäß dem . Oberbegriff des Schutzartspruches 1The innovation concerns an NH fuse strip according to the generic term of protection class 1
Bekannte auf Sammelschienen montierte und mit Abdeckungen versehene NH-Sicherungsleisten bieten üblicherweise im Betriebszustand von der Bedienungsseite her einen Schutz gegen direktes Berühren mit dean Finger.Known NH fuse strips mounted on busbars and provided with covers usually offer protection against direct contact with fingers from the operating side when in operation.
In elektrischen Anlagen; in denen derartige NH-Sicherungsleisten montiert und an denen Arbeiten unter Spannung erforderlich sind, werden auch die darin installierten Sammelschienen mit Isolierstoff ummantelt, um einen Schutz gegen zufälliges Berühren zu bieten.In electrical systems in which such NH fuse strips are installed and where work under voltage is required, the busbars installed in them are also covered with insulating material in order to provide protection against accidental contact.
Die Montage der NH-Sicherungsleisten erfolgt dann mittels Schneidringen, die an der Verbindungsstelle der Kontaktschienen der NH-Sicherungsleiste mit der zugeordneten Sammelschiene die Isolierung durchschneiden, so daß dann eine Kontaktierung über die Schneidringe erfolgt.The NH fuse strips are then mounted using cutting rings, which cut through the insulation at the connection point between the contact rails of the NH fuse strip and the associated busbar, so that contact is then made via the cutting rings.
Da jedoch in bestimmten elektrischen Anlagen die Sammelschienen auch von der Rückseite her zugängig sind, ist es erforderlich, auch von der Rückseite her den Schutz gegen direktes Berühren zu bieten.However, since in certain electrical systems the busbars are also accessible from the rear, it is necessary to provide protection against direct contact from the rear as well.
Aufgabe der Neuerung ist, bekannte NH-Sicherungleisten so weiterzubilden, daß diese einen allseitigen Schutz gegen direktes Berühren bieten.The aim of the innovation is to further develop known NH fuse strips so that they offer all-round protection against direct contact.
Diese Aufgabe wird neuerungsgemäß durch den kennzeichnenden Teil des Schutzanspruches 1 gelöst.This problem is solved according to the innovation by the characterizing part of claim 1.
Vorteilhafte Ausgestaltungen der Neuerung sind Gegenstand der Unteransprüche.Advantageous embodiments of the innovation are the subject of the subclaims.

It shows
Fig. 1 die auf eine Sammelschiene montierte NH-Sicherungsleiste, geschnitten an der Sammelschienen-befestigungsstelle, Fig. 2 einen Längsschnitt durch die mittig auf eine Sammelschiene montierte NH-Sicherungsleiste ohne frontseitige Abdeckungen undFig. 1 the NH fuse strip mounted on a busbar, sectioned at the busbar fastening point, Fig. 2 a longitudinal section through the NH fuse strip mounted centrally on a busbar without front covers and
Fig. 3 einen Längsschnitt durch die versetzt auf die Sammelschiene montierte NH-Sicherungsleiste ohne frontseitige Abdeckungen.Fig. 3 a longitudinal section through the NH fuse block mounted offset on the busbar without front covers.
Die NH-Sicherungsleiste, üblicherweise in 3-poliger Ausführung, ist zum Anschluß an Sammelschienen 2 geeignet, die in einem bestimmten Abstand zueinander angeordnet sind.The NH fuse strip, usually in 3-pole design, is suitable for connection to busbars 2 that are arranged at a certain distance from each other.
Die Steckkontaktteile 5 der jeweiligen Pole der NH-Sicherungsleiste werden mittels der Kontaktschienen 1 mit der Sammelschienen 2 elektrisch verbunden. Die Kontaktierung der Kontaktschiene 1 mit der Sammelschiene erfolgt über einen Schneidring 4, dessen umlaufende messerartige Schneidkante beim Anziehen der Klemmschraube den Isolierstoff 2A an der Sammelschiene 2 durchdringt und dann in die Oberfläche der Sammelschiene 2 eindringt.The plug contact parts 5 of the respective poles of the NH fuse strip are electrically connected to the busbar 2 by means of the contact rails 1. The contact rail 1 is contacted with the busbar via a cutting ring 4, the circumferential knife-like cutting edge of which penetrates the insulating material 2A on the busbar 2 when the clamping screw is tightened and then penetrates the surface of the busbar 2.
Sämtliche spannungsführenden Teile der NH-Sicherungsleiste sind allseitig durch die Gesamtheit der Abdeckungen 3,auch in Form von Schaltklappen zur Betätigung der eingesetzten NH-Sicherungseinsätze, berührungssicher abgedeckt, wobei jedes der an der Rückseite der NH-Sicherungsleiste befindlichen Abdeckungsteile 3A jeweils den Schneidring 4 und die Kontaktschiene 1 überdeckt.All live parts of the NH fuse strip are covered on all sides by the entirety of the covers 3, also in the form of switching flaps for operating the NH fuse inserts used, in a touch-safe manner, whereby each of the cover parts 3A located on the back of the NH fuse strip covers the cutting ring 4 and the contact rail 1.
Die einzelnen Abdeckungsteile 3A bieten gegenüber einer einteiligen Rückwand den Vorteil, daß Toleranzen des Sammelschienenabstandes und ein Versatz der KontaktSchraubenaufnahme problemlos ausgeglichen werden können.The individual cover parts 3A offer the advantage over a one-piece rear wall that tolerances in the busbar spacing and an offset in the contact screw receptacle can be easily compensated.

Die Abdeckungsteile 3A sind dabei formschlüssig an der Kontaktschiene 1 gehalten und längs der NH-Sicherungsleiste verschiebbar.The cover parts 3A are held in a form-fitting manner on the contact rail 1 and can be moved along the NH fuse strip.
Um die Schneidringe 4 auf den jeweiligen erforderlichen Befestigungsabstand zueinander einstellen zu können, sind den Abdeckungsteilen 3A Federarme 3Al zur Lagearretierung angeformt.In order to be able to adjust the cutting rings 4 to the required fastening distance from one another, spring arms 3Al are formed on the cover parts 3A for locking the position.
