Description
Verschraubung für Kabel, Schläuche u.ä. Kabelverschraubungen werden verwendet, um Kabel (e1. Leitung) durch Gehäusewände (Bchaltschränke, Motoren usw.) zu führen und dieselben gegeneinander abzudichten.Screw connection for cables, hoses, etc. Cable glands are used to route cables (1st line) through housing walls (switch cabinets, motors, etc.) to lead and seal them against each other.
Diese Abdichtung geschieht meist durch eine Gummi- oder Kunststoffdichtung welche durch eine Druckschraube zusammengequetscht wird und so die Abdichtung hervorruft.This seal is usually done with a rubber or plastic seal which is squeezed together by a pressure screw and thus creates the seal.
Im Laufe der Zeit beginnt dieses Dichtmaterial zu kriechen, d.h. der Druck innerhalb der Dichtung läßt nach und der Zweck der Verschraubung ist aufgehoben.Besonders bei älteren Anlagen kann man das abzudichtende Kabel in der Verschraubung hin- und herziehen und auf diese Weise sogar die Kabeladern von den Anschlußstellen abreißen welches eine große Gefahr darstellt (Körperschluß). Zur Vermeidung dieser Übelstände wird die Kabelverschraubung zusätzlich meist verkittet was zeitraubend und unschön ist.Eine Zugentlastung wird hierbei jedoch nicht erreicht. Die Neuerung besteht darin, daß das Kriechen des Dichtmaterials weitgehend vermindert und ;las Kabel sicher festgeklemmt wird (Zugentlastung).Over time, this sealing material begins to creep, i.e. the Pressure within the seal decreases and the purpose of the screw connection is canceled With older systems, the cable to be sealed can be back and forth in the screw connection pull and in this way even tear off the cable cores from the connection points which represents a great danger (body injury). To avoid these evils the cable gland is also usually cemented, which is time-consuming and unattractive However, strain relief is not achieved here. The innovation is there in that the creep of the sealing material is largely reduced and read cables is securely clamped (strain relief).
In dem Unterteil der neuen Katielvarsctiraubung befindet sich eine Druckhülse, welche mit mehreren 'linfräsungen (Schlitzen) versehen ist.Das obere Ende dieser s)ruckhülse ist abgeschrägt.In der Druckhülse befintiet sich das Dichtmaterial, welches eingespritzt ist und die Linfräsungen ausfüllt.In the lower part of the new Katielvarsctiraubung is located themselves a pressure sleeve, which is provided with several 'linfräsungen (slots) The upper end of this pressure sleeve is bevelled, which is located in the pressure sleeve Sealing material that is injected and fills the milled linings.
Jas Oberteil der neuen Verschraubung ist hier in r'orm einer @.berwurfmutter ausgeführt und ist an seinem oberen inneren Ende mit einer @3chrär;e versehen.3eim Aufschrauben des Oberteils auf :las unterteil rutscht die Druckhülse über die )chräge im Cberteil und verringert so ihren Durchmesjer.Gleichzeitig wird das innerhalb der Druckhülse befindliche i)icht@naterial zusammengepreht und dichtet ;las Kabel ab, während es von dem oberen Teil der Druckhülse festgeklemmt Die -@^aci@ r@i? se ist leicht abgerundet (Biegeschutz) um Kabelverletzungen zu vermeiden und klemmt das Kabel fest, wodurch eine sichere Zugentlastung gewährleistet ist.The upper part of the new screw connection is here in the form of a union nut and has a @ 3chrär; e at its upper inner end Unscrew the upper part: the lower part slides the pressure sleeve over the incline in the upper part and thus reduces its diameter. At the same time, this becomes within The i) icht @ naterial located on the pressure sleeve is twisted together and sealed; the cable off while it is clamped by the upper part of the compression sleeve The - @ ^ aci @ r @ i? It is slightly rounded (bending protection) to avoid cable injuries and jams the cable tightly, which ensures reliable strain relief.
Durch die Druckhülse ist die neue Verschraubung an ihrem oberen Ende dicht abgeschlossen, so daß sich kein Schmutz (z3.rnetall.äpäne) darin ansammeln kann.The new screw connection is at its upper end through the pressure sleeve tightly sealed so that no dirt (e.g. metal chips) collects in it can.
Durch die lange Druckhülse wird das Kabel auf einer großen Länge abgedichtet.The long pressure sleeve seals the cable over a great length.
Häufig werden auch metalldrahtumhüllte Kabel verwendet, wobei das Drahtgeflecht zum-ichutz des Kabels und zur Erdung dent:Durch die metallische Klemmhülse wird eine einwandfreie Erciüng gewährleistet.Metal wire sheathed cables are also often used, whereby the Wire mesh for the protection of the cable and for earthing dent: Through the metallic clamping sleeve a perfect result is guaranteed.
Während die normalen Kabelverschraubungen aus 5 Einzelteilen bestehen, besteht die neue Kabelverschraubung aus ? bzw. 2 .sinzelteilen, die wenir-er leicht bei der '"ontacre verlorengehen.While the normal cable glands consist of 5 individual parts, the new cable gland exists the end ? or 2 .individual parts, which wenir-er easily get lost in the '"ontacre.
iIit der neuen Nabelverschraubung kann man auch sehr gut -etallschläuche und bei zusätzlicher Verwendung einer einfachen Hülse auch flexible .;chläucrle (:Wasserschlauch) vorschräuben.With the new umbilical screw connection you can also use metal hoses very well and if a simple sleeve is also used, flexible.; chläucrle (: Water hose).
Jie Lagerhaltung wird durch die neue Verschrauourlg sehr vereinfacht, da für die verschiedensten :ibrnessungen der Kabel und Schläuche nur wenige Verschraubungen erforderlich sind.Warehousing is very much simplified by the new screwing arrangement, there are only a few screw connections for the most varied of: ibrations of cables and hoses required are.
`-'egen der vielseitigen Verwendungsmöglichkeit und einfachsten ''ontage soll die neue Verschraubung als " Fix - Verschraubung " in den Handel kommen. Die neue "Fix- Verschraubung" ist in den 'Zeichnungen in einigen Ausführungsbeispielen dargestellt.`` -'because of the versatility of use and the simplest '' ontage the new screw connection is to come on the market as a "fix screw connection". the new "fix screw connection" is in the 'drawings in some embodiments shown.
Es zeigt: Fig.1 einen Schnitt durch die Verschraubung öemäß der Erfindung, Fig.2 eine Seitenansicht der Verschraubung (halb geschnitten), Fig.3 einen Schnitt durch die 2-teilige Verschraubung, Fig.4 einen Schnitt durch die Verschraubung als Schlauchverschraubung Wie Fig. 1 und 2 zeigen, ist das Unterteil (1) mit zwei Gewinden (2) und (3) versehen.Das Gewinde (2) dient zur Verschraubung mit der Gehäusewand (4) mit der Gegenmutter (5).Der Buncj (6) dient als jinlagefläche an die Gehäusewand (4).Das Gewinde (3) dient zum Aufschrauben des Cberteils (7), welches innen abgeschrägt ist.It shows: FIG. 1 a section through the screw connection according to the invention, FIG. 2 a side view of the screw connection (half-cut), FIG. 3 a section through the 2-part screw connection, FIG. 4 a section through the screw connection as a hose screw connection Fig. 1 and 2 show, the lower part (1) is provided with two threads (2) and (3). The thread (2) is used for screwing to the housing wall (4) with the counter nut (5). The Buncj (6 ) serves as a support surface on the housing wall (4). The thread (3) is used to screw on the upper part (7), which is beveled on the inside.
Jie Druckhülse (i3) befindet sich im Unterteil (1) und enthält das Dichtmaterial (9).Jas obere Ende der Druckhülse (8) kann zur Vermeidung von Kabelbeschädigungen leicht abgerundet sein.Die Druckhülse ist mit schlitzartigen Einfräsungen (1o) versehen.The pressure sleeve (i3) is located in the lower part (1) and contains the Sealing material (9). The upper end of the pressure sleeve (8) can be used to prevent cable damage The pressure sleeve is provided with slot-like millings (1o).
Beim Aufschrauben des Oberteils (7) auf das Unterteil (1) wird die Druckhülse (8) durch die Schräge im Oberteil (7) in ihrem Innendurchmesser verkleinert und gleichzeitig die Dichtung (9) zusammengepreßt.Hierdurch wird das Kabel (11) festgeklemmt (zugentlastet) und gleichzeitig abgedichtet.When screwing the upper part (7) onto the lower part (1), the The inner diameter of the pressure sleeve (8) is reduced by the incline in the upper part (7) and at the same time the seal (9) is pressed together. This causes the cable (11) clamped (strain-relieved) and sealed at the same time.
Wie Fig.3 zeigt, ist die Druckhülse hier Bestandteil des Unterteils (1).Die Einfräsungen (1o) reichen bis zum Gewindeanfang (3).Durch diese Bauart besteht die Verschraubung nur aus zwei Einzelteilen.As Figure 3 shows, the pressure sleeve is part of the lower part here (1). The millings (1o) extend to the start of the thread (3) the screw connection only consists of two individual parts.
