Description

Die Erfindung bezieht sich auf eine Schließkanten-Sicherung gemäß dem Oberbegriff des Anspruches 1 und des Anspruches 4.The invention relates to a closing edge safety device according to the preamble of claim 1 and claim 4.

Schließkanten-Sicherungen sind in einer Vielzahl unterschiedlich ausgebildeter Anordnungen z. B. aus der FR 21 35 922 A1 , der EP 103 726 B1 oder der EP 234 523 B1 oder der WO 97/38199 bekannt. All diesen Schließkanten-Sicherungen ist eigen, daß in einem elastisch verformbaren Schlauch Kontaktelemente angeordnet sind, die bei Einwirkung eines Verformungsdruckes auf den Schlauch einen elektrischen Schaltkontakt auslösen, der eine Sicherheitsfunktion schaltet.Locking edge fuses are in a variety of differently designed arrangements z. B. from the FR 21 35 922 A1 , of the EP 103 726 B1 or the EP 234 523 B1 or the WO 97/38199 known. All these locking edge fuses is peculiar that contact elements are arranged in an elastically deformable hose, which trigger an electrical switching contact upon the action of a deformation pressure on the hose, which switches a safety function.

Die elektrischleitend miteinander in Verbindung stehenden Kontaktelemente benötigen eine Kabeldurchführung durch den elastischen Schlauch zu der elektrischen Schalteinrichtung, und diese Kabeldurchführung bereitet erhebliche Schwierigkeiten. Einmal ist nicht sichergestellt, daß die Kabeldurchführung absolut feuchtigkeitsdicht ist, sondern durch Bewegungen des Schlauches in der Kabeldurchführung können Freiräume entstehen, die das Eindringen von Feuchtigkeit in den die Kontaktelemente aufnehmenden Raum des Schlauches ermöglichen. Zum anderen wirken auf das Kabel Zugkräfte, die sich bis in den Schlauch fortführen können. Weiterhin treten Biegebeanspruchung im Bereich des Leitungsaustrittes aus dem Schlauch auf, die zu Zerstörungen der Kabeladern führen können, so daß Fehlschaltungen auftreten. Auch auf die eigentliche Schließkanten-Sicherung einwirkende Wärmebeanspruchungen führen zu einem unterschiedlichen Dehnen des Schlauches und des Signalgebers, also der Kontaktkette, so daß auch hier Beanspruchungen des Kabel auftreten und was bisher dazu zwingt, Kabellängen innerhalb des Schlauches vorzusehen, um diese unterschiedlichen Ausdehnungen beherrschen zu können. Diese innerhalb des Schlauches vorzusehenden Kabelschlaufen führen wiederum leicht zu Kabelbrüchen und damit zu Fehlschaltungen.The electrically conductive interconnected contact elements require a cable bushing through the elastic hose to the electrical switching device, and this cable feedthrough prepares considerable difficulties. Once it is not ensured that the cable gland is completely moisture-proof, but by movements of the hose in the cable gland can open spaces, the penetration of moisture in the contact elements Allow receiving space of the hose. On the other hand act on the cable tensile forces that can continue into the tube. Furthermore, bending stress occur in the region of the line outlet from the hose, which can lead to destruction of the cable cores, so that faulty circuits occur. Also acting on the actual closing edge fuse thermal stresses lead to a different stretching of the hose and the signal generator, so the contact chain, so that here too stresses of the cable occur and what forces so far to provide cable lengths within the hose to dominate these different dimensions can. These cable loops to be provided inside the hose in turn lead easily to cable breaks and thus to faulty circuits.

In der FR-A 21 35 922 erfolgt der Abschluß des Schlauches durch einen gut elektrisch leitende Eigenschaften aufweisenden Stopfen, der also aus Metall besteht. Wie die unbedingt erforderliche elektrische Isolierung dieses Verschlußelementes erreicht wird, geht aus dieser Literaturstelle nicht hervor. Da der eigentliche Schlauch unter erheblicher Spannung steht, um den erforderlichen Kontakt der Kontaktelemente sicherzustellen, erscheint das Einsetzen eines einfachen elektrisch leitenden Verschlußstopfens in das Innere des Schlauches in der Praxis nicht durchführbar.In the FR-A 21 35 922 the conclusion of the tube by a good electrical conductivity properties having plug, which therefore consists of metal. How the absolutely necessary electrical insulation of this closure element is achieved does not emerge from this reference. Since the actual tube is under considerable tension to ensure the required contact of the contact elements, the insertion of a simple electrically conductive stopper into the interior of the tube in practice appears impracticable.

In der DE 196 47 721 erfolgt der Abschluß des Schlauchinnenraumes dadurch, daß der Schlauch durch eine Scheibe abgeschlossen wird, die an ihrem äußeren Ende zylinderförmig verlängert ist. Diese Verlängerung besitzt einen geringeren Durchmesser als die Scheibe und schafft eine Schulter, über die ein Ring gestülpt wird, wobei zwischen der Innenseite des Ringes und der einen geringeren Durchmesser aufweisenden Verlängerung der Schlauch eingeklemmt werden soll. Das Festlegen des Ringes und des Schlauches erfolgt durch eine Schraube.In the DE 196 47 721 the conclusion of the tube interior is characterized in that the tube is closed by a disc which is extended in a cylindrical shape at its outer end. This extension has a smaller diameter than the disc and creates a shoulder over which a ring is slipped, wherein between the inside of the ring and the smaller diameter having extension of the hose to be clamped. The fixing of the ring and the hose is done by a screw.

Auch diese Anordnung ist nicht praxisgerecht, da nicht erkennbar ist, wie es möglich sein soll, einen Schlauch in seinem Durchmesser zu verringern, ohne daß sich Falten oder Wölbungen bilden, durch die Feuchtigkeit eindringen kann. Da der Schlauch zudem durch die eingesetzte Schraube verletzt wird, besteht auch die Gefahr, daß Feuchtigkeit eintritt, was einerseits zu Fehlkontakten, andererseits zu Korrosionen der Kontaktelemente führen kann.Also, this arrangement is not practical, since it is not clear how it should be possible to reduce a hose in its diameter, without forming wrinkles or bulges through which moisture can penetrate. Since the hose is also injured by the screw used, there is also the risk that moisture enters, which can lead to incorrect contacts, on the one hand, on the other hand, to corrosion of the contact elements.

In der DE 196 47 721 wird außerdem der erforderliche Anlagedruck der Kontaktelemente aneinander durch ein Federelement geschaffen.In the DE 196 47 721 In addition, the required contact pressure of the contact elements is created together by a spring element.

Der Erfindung liegt die Aufgabe zugrunde, eine Entkopplung der Sensorkette von dem nach außen führenden Signalübertrager, d. h. dem Kabel herbeizuführen, und dabei eine sichere und von einwirkenden Kräften unabhängige Kabeldurchführung zu schaffen.The invention is based on the object of decoupling the sensor chain from the outwardly leading signal transformer, d. H. To bring the cable, while creating a safe and acting forces independent cable feedthrough.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehren des Anspruches 1 und des Anspruches 4 gelöst.This object of the invention is achieved by the teachings of claim 1 and claim 4.

Vorteilhafte Ausgestaltungen sind in den Unteransprüchen erläutert.Advantageous embodiments are explained in the subclaims.

Mit anderen Worten wird vorgeschlagen, daß der die Kontaktkette oder den Signalgeber aufnehmende Raum des Schlauches nach außen hin durch einen Verschlußelement verschlossen wird, das eine elektrischleitende Kontaktbrücke trägt, so daß das Einführen eines Kabels in den die Kontaktelemente aufnehmenden Raum des Schlauches nicht mehr notwendig ist.In other words, it is proposed that the contact chain or the signal transducer receiving space of the tube is closed to the outside by a closure element which carries an electrically conductive contact bridge, so that the insertion of a cable in the contact elements receiving space of the hose is no longer necessary ,

Die Kontaktbrücke kann formschlüssig oder materialschlüssig mit dem Verschlußelement verbunden sein, d. h. es ist möglich, das Verschlußelement z. B. aus einem Gummiformartikel herzustellen und die Kontaktbrücke einzuvulkanisieren, wobei die Kontaktbrücke auch durch eine Art Labyrinthdichtung zusätzlich innerhalb des Verschlußelementes gesichert sein kann. Das Einvulkanisieren der Kontaktbrücke in einem aus Gummi oder gummiartigen Werkstoff bestehenden Formteil bewirkt eine absolut feste und dichte Verbindung.The contact bridge may be positively or materially connected to the closure element, ie it is possible for the closure element z. B. produce from a rubber molded article and to vulcanize the contact bridge, wherein the contact bridge can also be secured by a kind of labyrinth seal within the closure element. The vulcanization of the contact bridge in a molding made of rubber or rubber-like material causes an absolutely solid and tight connection.

Das Verschlußelement kann dabei gemäß der Erfindung einerseits als Verschlußstopfen ausgebildet sein, der in das Innere des Schlauches eingesetzt wird und mit einer Verschlußkappe zusammenarbeitet. Die im Schlauch im Verschlußstopfen und in der Verschlußkappe erforderliche Kabeldurchführung kann nach Einsetzen des Kabels stoffschlüssig verschlossen werden, so daß hier eine absolute Feuchtigkeitssicherung erreicht wird. Gemäß einem anderen Merkmal der Erfindung besteht das Verschlußelement aus einer Verschlußhaube, die den Schlauch übergreift und ihrerseits dann von einer Verschlußkappe übergriffen wird, die als Schrumpfelement ausgebildet ist. Schrumpffolien und Schrumpfschläuche sind im Stand der Technik bekannt und durch den Einsatz dieser Werkstoffe wird ebenfalls wiederum eine absolut sichere Abdichtung des Schlauches erreicht und gleichzeitig die erforderliche Festlegung des Verschlußelementes im oder am Schlauch.The closure element may be formed according to the invention on the one hand as a plug, which is inserted into the interior of the tube and cooperates with a cap. The cable bushing required in the hose in the stopper and in the closure cap can be firmly closed after insertion of the cable, so that an absolute moisture protection is achieved here. According to another feature of the invention, the closure element consists of a closure cap, which engages over the tube and in turn is overlapped by a closure cap, which is formed as a shrink element. Shrink films and heat shrink tubing are known in the art and by the use of these materials, in turn, an absolutely secure sealing of the hose is achieved and at the same time the required determination of the closure element in or on the hose.

Innerhalb des die Kontaktelemente aufnehmenden Raumes des Schlauches ist zwischen der nach innen vorstehenden Kontaktbrücke des Verschlußstopfens und dem letzten zur Kontaktbrücke hinweisenden Kontaktelement ein elektrischleitendes Federelement angeordnet, das nunmehr einerseits die innerhalb des Schlauches angeordneten Kontaktelemente aneinanderlegt, andererseits eine elektrischleitende Verbindung von den Kontaktelementen zur Kontaktbrücke schafft, so daß das Einsetzen eines Kabels in den Schlauch nicht mehr notwendig ist.Within the space of the tube receiving the contact elements, an electrically conductive spring element is arranged between the inwardly projecting contact bridge of the stopper and the last pointing to the contact bridge contact element, now on the one hand juxtaposed arranged within the tube contact elements, on the other hand creates an electrically conductive connection of the contact elements to the contact bridge so that the insertion of a cable into the hose is no longer necessary.

Durch die erfindungsgemäße Anordnung wird erreicht, daß, ohne Kabel im Schlauch einsetzen zu müssen, eine Verbindung von der Anschlußleitung zur Kontaktkette sichergestellt ist. Es wird ein absolut dichter Abschluß des die Kontaktelemente aufnehmenden Raumes des Schlauches erreicht, und es wird eine Trennung der Zugkräfte von mechanischen Beanspruchungen bewirkt. Ein Ausgleich zwischen den Bewegungen des Schlauches und der Kontaktkette wird durch Federn sichergestellt.The inventive arrangement ensures that, without having to use cables in the hose, a connection is ensured by the connection line to the contact chain. It is an absolutely tight closure of the contact elements receiving space of the hose achieved, and it is a separation of the tensile forces caused by mechanical stresses. A balance between the movements of the hose and the contact chain is ensured by springs.

Zusätzlich wird erreicht, daß durch die erfindungsgemäße Anordnung eine einfachere Montage der Schaltleiste möglich ist, weil keine langen Anschlußleitungen mit verarbeitet werden müssen, und die Anschlußleitung kann prinzipiell beliebig lang den örtlichen Verhältnissen angepaßt ausgeführt werden.In addition, it is achieved that a simpler installation of the switching strip is possible by the arrangement according to the invention, because no long leads must be processed with, and the lead can be performed arbitrarily long in principle adapted to the local conditions.

An diese Kontaktbrücke 4 schließt einenendes ein Kabel 5 an und anderenendes liegt an einer entsprechenden Kontaktplatte der Kontaktbrücke 4 ein elektrisch leitendes Federelement 6 an, das mit seinem anderen Ende die letzte zur Kontaktbrücke 4 hinweisende Kontaktelemente 2 beaufschlagt. Dieses Federelement 6 kann beliebig ausgebildet sein. So ist in den Zeichnungen in Fig. 4 und 5 eine Wendelfeder dargestellt, während in Fig. 6 das Federelement 6 ein einfaches Blattfederelement ist.With reference to the 4 to 6 is an elastic hose recognizable, in which a contact chain of individual contact elements 2 is arranged. The space in which the contact elements are arranged is closed to the outside by a closure element having an electrically conductive contact bridge 4.

In die Bodenplatte 8 des Verschlußstopfens 3 ist die Kontaktbrücke 4 einvulkanisiert. In diesen nach außen hin offenen Verschlußstopfen 3 kann eine Verschlußkappe 7 eingesetzt werden, die eine Wandung 10 und eine Abschlußplatte 11 aufweist, wobei auch hier die Wandung 10 nicht voll umlaufend sein muß, sondern aus einzelnen lamellenartigen Elementen bestehen kann. Die Öffnungen zur Durchführung des Kabels 5 sind in Fig. 1 erkennbar, und wenn das Verschlußelement beispielsweise gemäß Fig. 4 in den Schlauch 1 eingesetzt ist, können die miteinander korrespondierenden Öffnungen materialschlüssig verschlossen werden.According to Fig. 1 is the actual closure element designed as a plug 3, which is cup-shaped and has a circumferential wall 9, said wall 9 does not have to be fully encircling, but it can be provided individual wall elements. In the bottom plate 8 of the stopper 3, the contact bridge 4 is vulcanized.

Bei der Ausführungsform gemäß Fig. 2 und 3 ist das Verschlußelement als Verschlußhaube 12 ausgebildet und weist ebenfalls eine Abschlußplatte 14 auf, in die die Kontaktbrücke 4 einvulkanisiert ist. Diese Verschlußhaube 12 übergreift das offene Ende des Schlauches 1 und wird ihrerseits von einer Verschlußkappe 70 übergriffen, deren Wandung 100 an der Außenseite sowohl der Verschlußhaube 12 wie auch einem Teil des Schlauches 1 anliegt. Wenn diese Verschlußkappe 70 aus schrumpfendem Material hergestellt ist entsprechend einer Schrumpffolie oder eines Schrumpfschlauches, erfolgt eine dichte Festlegung der Verschlußkappe 70 auf der Außenseite der Verschlußhaube 12 und des Schlauches 1.
