Gemäß den Vorschriften des Vereins deutscher Elektrotechniker ist für Klemmen ein bestimmter Kriechweg und Überschlagweg in Luft an den Stoßstellen zweier benachbarter S Klemmen von der gemeinsamen, elektrisch leitenden Tragschiene der Klemmen bis zu deren spannungführenden Teilen entsprechend der Höhe der Spannung vorgeschrieben. Wenn eine für eine bestimmte Spannung, beispielsweise 500 Volt, bemessene Klemme für eine höhere Spannung, beispielsweise 1500 Volt, verwendet werden soll, so ist der obenerwähnte Überschlagweg, der durch die Konstruktion festgelegt ist, viel zu klein. Es müßten also größer dimensionierte Klemmen verwendet werden, oder, wenn man dies vermeiden wollte, die Klemmen statt auf Eisenschienen auf Isolierschienen aufgereiht werden. Diese Auswechslung der TragschienenAccording to the regulations of the Association of German Electrical Engineers, a certain creepage distance and rollover path in air at the joints between two neighboring ones S Terminals from the common, electrically conductive mounting rail of the terminals up to their live parts are prescribed according to the voltage level. if a terminal rated for a specific voltage, for example 500 volts, for a higher voltage, for example 1500 volts, is to be used, then that mentioned above The rollover path, which is determined by the construction, is much too small. So larger sized terminals would have to be used or, if you wanted to avoid this, the clamps instead of iron rails be lined up on insulating rails. This replacement of the mounting rails
eo ist, da hierbei die ganze bestehende Klemm-' anordnung abmontiert werden muß, sehr umständlich und erfordert demgemäß viel Zeit. Die Erfindung bezweckt nun, die für gewöhnlich für eine bestimmte Spannung, beispielsweise 500 Volt, bemessenen Klemmen in einfacher Weise auch für höhere Spannungen, etwa 1500 Volt, verwendbar zu machen. Dies wird erfindungsgemäß dadurch erreicht, daß zur künstlichen Vergrößerung des der jeweiligen Spannung entsprechenden Überschlagweges von der elektrisch leitenden Tragschiene zu dem spannungführenden Teil der Klemmen ein aus Isoliermaterial bestehendes Kernstück in Ausparungen zweier benachbarter Klemmen auswechselbar vorgesehen ist. Durch die Aussparungen wird gleichzeitig auch der Kriechweg an den Stoßstellen, die bisher glatt durchgehend ausgebildet waren, vergrößert.eo, since here the whole existing clamping ' arrangement must be dismantled, very cumbersome and accordingly requires a lot of time. The invention now aims, usually for a certain voltage, for example 500 volt, sized terminals can be used in a simple manner for higher voltages, about 1500 volts. this is achieved according to the invention that for the artificial enlargement of the respective Voltage of the corresponding flashover path from the electrically conductive mounting rail to the live part of the terminals a core piece made of insulating material in recesses of two adjacent ones Terminals is provided interchangeably. At the same time, the recesses also reduce the creepage distance at the joints, which were previously smooth and continuous, enlarged.
Zweckmäßig dient das Kernstück gleichzeitig dazu, eine an sich bekannte Isoliertrennwand zu tragen, welche über die Kanten der Seitenwand des Isolierkörpers der Klemmen hinausragt und zur Vergrößerung des Kriechweges und Überschlagweges in Luft zwischen den Metallteilen benachbarter Klemmen dient.The core piece expediently serves at the same time as an insulating partition wall known per se to wear, which protrudes over the edges of the side wall of the insulating body of the terminals and to enlarge the Creepage and rollover path in air between the metal parts of adjacent terminals serves.

Ansatz 2 besitzt, mit dem es auf den Klemmen aufliegt. Das Kernstück 1 ruht in den Aussparungen 3 der Klemmen 4 und 4', die auf der gemeinsamen Tragschiene 6 aufgereiht sind. Dieses Kernstück kann beim Aufreihen der Klemmen seitlich eingelegt bzw. bei nachträglicher Verwendung bei fertig montierten Klemmenreihen von oben eingeführt werden. Die isolierende Trennwand 5 besteht im dargestellten Ausführungsbeispiel aus einem Stück mit dem Kernstück i. Die beiden Teile können aber auch für sich hergestellt und nachträglich in geeigneter Weise miteinander verbunden werden.Approach 2 has, with which it rests on the terminals. The core 1 rests in the Recesses 3 of the terminals 4 and 4 ', which are lined up on the common mounting rail 6 are. This core piece can be inserted at the side when the terminals are lined up or when used at a later date completely assembled rows of terminals can be inserted from above. The insulating partition 5 consists in the illustrated embodiment of one piece with the core piece i. However, the two parts can also be produced individually and subsequently in a suitable manner Way to be connected.
