Description

Die Erfindung betrifft eine elektrische Heizpatrone mit Anschlussleitung, wobei die Heizpatrone einen metallischen Mantel aufweist, in welchem mindestens ein elektrischer Leiter isoliert angeordnet ist, der mit einem metallischen Anschlussstift verbunden ist, der aus dem Mantel vorragt, wobei die Anschlussleitung an einem Endbereich freigelegt ist, im freigelegten Bereich von einem Gehäuse umgeben ist, wobei das Gehäuse eine am freien Ende der Anschlussleitung fixierte Kontaktbuchse umgibt, in die der Anschlussstift einsteckbar oder eingesteckt ist, wobei schließlich das Gehäuse mit der Heizpatrone unmittelbar lösbar verbunden oder verbindbar ist.The invention relates to an electrical heating cartridge with connecting cable, wherein the heating cartridge has a metallic shell in which at least one electrical conductor is arranged insulated, which is connected to a metallic pin protruding from the jacket, wherein the connecting cable is exposed at an end region, is surrounded by a housing in the exposed area, wherein the housing surrounds a fixed at the free end of the connecting line contact socket into which the pin is inserted or plugged in, finally, the housing with the heating cartridge is directly releasably connected or connectable.

Aus der DE 34 27 207 C2 ist eine solche Anordnung bekannt. Vorteilhaft bei der bekannten Ausbildung ist, dass es in einfacher Weise möglich ist, bei einer defekten Heizpatrone allein diese Heizpatrone auszutauschen, ohne dass die Zuleitung neu verlegt werden muss. Vielmehr kann die elektrische Zuleitung in ihrer ursprünglichen Position verbleiben. Dies ist insbesondere bei üblichen Spritzgusswerkzeugen von besonderer Bedeutung, die mit solchen Heizpatronen beheizt werden, da solche Spritzgusswerkzeuge häufig mehrere hundert solcher Heizpatronen einschließlich Anschlussleitungen aufweisen. Eine solche Ausbildung ist aber nicht nur bei verlegten Heizpatronen nebst Anschlussleitungen vorteilhaft, sondern es ist auch vorteilhaft, dass solche Heizpatronen separat gefertigt und bevorratet werden können und die dazugehörigen Anschlussleitungen in unterschiedlicher Länge ebenfalls standardmäßig konfektioniert vorgehalten werden können. Sofern eine entsprechende Kombination verwendet werden soll, wird eine elektrische Heizpatrone mit einer passenden Anschlussleitung kombiniert. Bei der im Stand der Technik bekannten Ausbildung hat die Heizpatrone einen kleinen Durchmesser von beispielsweise 4mm.From the DE 34 27 207 C2 Such an arrangement is known. An advantage of the known design is that it is possible in a simple manner to replace this heating cartridge alone with a defective immersion heater without the supply line must be relocated. Rather, the electrical supply line can remain in its original position. This is especially true at conventional injection molds of particular importance, which are heated with such cartridges, since such injection molds often have several hundred such cartridges including connecting cables. However, such a design is advantageous not only for installed heating cartridges together with connecting lines, but it is also advantageous that such heating cartridges can be manufactured and stored separately and the associated connection cables in different lengths can also be kept ready made by default. If an appropriate combination is to be used, an electric immersion heater is combined with a suitable connecting cable. In the training known in the art, the heating cartridge has a small diameter of for example 4mm.

Bei der bekannten Ausbildung ist nachteilig, dass die Anschlussleitung in einem Endbereich von einem formfesten Isolierkörper aus Keramik umgeben ist, in dem die Kontakthülsen angeordnet sind, wobei dieser Isolierkörper von einem metallischen Gehäuse umgeben ist. Zusätzlich sind noch Dichtelemente in Form eines Stopfens aus Silikon in dem Gehäuse unterzubringen und die Abdichtung zwischen der elektrischen Zuleitung und dem Gehäuse sowie den im Gehäuse befindlichen Einzelteilen ist problematisch. Auch ist die lösbare Verbindung des Gehäuses mit dem Mantel der Heizpatrone kompliziert, weil im Stand der Technik dazu zwar eine Gewindeverbindung angegeben ist, wobei aber bei dieser Ausgestaltung das umgebende Gehäuse relativ zum Isolierstoffkörper samt Stopfen verdrehbar angeordnet sein muss. Dies führt weiterhin zu erheblichen Problemen bezüglich der abgedichteten Ausbildung und Anordnung gegenüber Umwelteinflüssen.In the known embodiment is disadvantageous that the connection line is surrounded in an end region by a dimensionally stable insulating body made of ceramic, in which the contact sleeves are arranged, said insulating body is surrounded by a metallic housing. In addition, sealing elements in the form of a plug made of silicone still be accommodated in the housing and the seal between the electrical supply line and the housing and the individual parts located in the housing is problematic. Also, the detachable connection of the housing with the jacket of the heating cartridge is complicated, because in the prior art to a threaded connection is specified, but in this embodiment, the surrounding housing relative to Insulating body must be arranged rotatable together with stopper. This further leads to significant problems with respect to the sealed training and arrangement with respect to environmental influences.

Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine elektrische Heizpatrone mit Anschlussleitung zu schaffen, die unter Beibehalt des Vorteils der leichten Auswechselbarkeit der Heizpatrone ohne Anschlussleitung eine vereinfachte Fertigung, eine sichere Montage und eine hohe Dichtigkeit gegen Umwelteinflüsse wie Hydrauliköl, Spritz- oder Schwallwasser gewährleistet. Dabei soll zudem eine hohe Zugfestigkeit zwischen Heizpatrone und der angesteckten Anschlussleitung erreicht werden.Based on this prior art, the present invention seeks to provide an electric immersion heater with connecting cable, while maintaining the advantage of easy interchangeability of the immersion heater without connection line a simplified manufacturing, safe installation and high tightness against environmental influences such as hydraulic oil, spray - or splash water guaranteed. In addition, a high tensile strength between the heating cartridge and the infected connecting cable should be achieved.

Zur Lösung dieser Aufgabe schlägt die Erfindung vor,
dass auf die Heizpatrone endseitig eine metallische Hülse aufgesteckt und mit dem Mantel der Heizpatrone formfest und fluiddicht verbunden ist, in die das Ende des elektrischen Leiters der Heizpatrone hineinragt,
dass das Ende des Leiters mit dem metallischen Anschlussstift innerhalb der Hülse verbunden ist, wobei der Anschlussstift bis zur der Heizpatrone abgewandten Mündung der Hülse vorragt oder über diese hinausragt,
dass die Hülse in dem Bereich, in welchen das Ende der Heizpatrone hineinragt und in dem der Leiter mit dem Anschlussstift verbunden ist, sowie über einen Teil der Länge des Anschlussstiftes mit Isoliermaterial, insbesondere einer Glasschmelze, gefüllt ist, mittels derer eine abgedichtete, zentrierte und mechanisch feste Anordnung der Teile zueinander erfolgt,
dass die Hülse an ihrem der Heizpatrone abgewandten Ende ein Außengewinde aufweist, dass die am freien Ende der Anschlussleitung fixierte Kontaktbuchse samt des an diese anschließenden Endbereichs der Anschlussleitung von einem aufgeformten Kunststoffformteil umgeben ist, welches mit der Einstecköffnung der Kontaktbuchse offen endet und in die Hülse einsteckbar ist, so dass der Anschlussstift in die Kontaktbuchse eingreift,
dass am Mantel des Kunststoffformteils mit Abstand von dessen offenem Ende ein nach außen abragender Mitnehmer angeformt ist, an dem sich ein Kragen einer Überwurfmutter abstützt, die drehbar auf dem Kunststoffformteil angeordnet ist und mit ihrem Innengewinde auf das Außengewinde der Hülse aufschraubbar oder aufgeschraubt ist, wobei in einem Bereich zwischen einer Stirnfläche des Mitnehmers und einer Stirnfläche der Hülse ein Dichtelement angeordnet ist, und
dass schließlich das Kunststoffformteil im Bereich zwischen dem Umgriff der Überwurfmutter bis zur austretenden Anschlussleitung sowie über einen Teilbereich der Anschlussleitung, die über das Formteil vorragt, von einem Schrumpfschlauch umgeben und durch diesen gedichtet ist.To solve this problem, the invention proposes
in that a metallic sleeve is attached to the end of the heating cartridge and connected in a dimensionally stable and fluid-tight manner to the jacket of the heating cartridge into which the end of the electrical conductor of the heating cartridge protrudes,
in that the end of the conductor is connected to the metallic connecting pin inside the sleeve, wherein the connecting pin protrudes or projects beyond the mouth of the sleeve facing away from the heating cartridge,
that the sleeve in the region in which the end of the heating cartridge protrudes and in which the conductor is connected to the pin, and over a part of the length of the connecting pin with insulating material, in particular a glass melt is filled, by means of which a sealed, centered and mechanically fixed arrangement of the parts takes place to one another,
in that the sleeve has an external thread on its end facing away from the heating cartridge, that the contact bush fixed at the free end of the connecting lead is surrounded by a shaped plastic molded part which ends openly with the insertion opening of the contact bush and can be inserted into the sleeve is such that the pin engages the contact socket,
that on the jacket of the plastic molded part at a distance from the open end an outwardly projecting driver is integrally formed on which a collar of a union nut is supported, which is rotatably mounted on the plastic molding and screwed with its internal thread on the external thread of the sleeve or screwed, wherein in a region between an end face of the driver and an end face of the sleeve, a sealing element is arranged, and
that finally the plastic molded part in the area between the gripping of the union nut to the exiting connecting line and over a portion of the connecting line, which projects beyond the molded part, surrounded by a shrink tube and sealed by this.

Gemäß dieser Ausgestaltung wird in einfacher Weise einerseits die gegen Umwelteinflüsse dichte Anordnung und Ausbildung eines ersten Elementes am Körper der Heizpatrone sichergestellt und andererseits eine ebensolche Ausbildung am Ende der Anschlussleitung, wobei beide Elemente in einfacher Weise steckverbunden werden können und durch die Überwurfmutter in einfacher Weise fixiert werden können, wobei auch im Trennbereich zwischen den beiden Teilen eine hervorragende Abdichtung erreicht wird. Eine solche Ausgestaltung ermöglicht eine schlanke Anordnung der Kupplungsbestandteile, so dass der benötigte Einbaurahmen relativ gering ist. Die anzuschließenden Heizpatronen können Standardbauteile sein, die in üblicher Weise gefertigt werden und zur Verfügung stehen. Ebenso ist die elektrische Anschlussleitung ein Standardbauteil, welches ohne besondere Maßnahmen zu Verfügung steht.According to this embodiment, on the one hand, the tightly sealed against environmental influences arrangement and formation of a first element on the body of the heating cartridge and on the other hand, a similar training at the end the connection line, wherein both elements can be plugged into a simple manner and can be fixed by the union nut in a simple manner, with an excellent seal is achieved in the separation area between the two parts. Such a configuration allows a slender arrangement of the coupling components, so that the required mounting frame is relatively low. The heating cartridges to be connected can be standard components that are manufactured and available in the usual way. Likewise, the electrical connection cable is a standard component, which is available without special measures.

Bevorzugt ist bei der erfindungsgemäßen Gestaltung, dass das Dichtelement ein O- Ring ist.In the design according to the invention, it is preferred that the sealing element is an O-ring.

Insbesondere ist bevorzugt, dass das Dichtelement aus hochtemperaturfestem Silikon besteht.In particular, it is preferred that the sealing element consists of high temperature resistant silicone.

Darüber hinaus ist bevorzugt vorgesehen, dass das Kunststoffformteil aus hochtemperaturfestem, spritzfähigem Kunststoff besteht.In addition, it is preferably provided that the plastic molded part consists of high temperature resistant, injection-moldable plastic.

Besonders bevorzugt ist zudem vorgesehen, dass der Schrumpfschlauch außenliegend aus einer Schicht aus duroplastischem Polytetrafluoräthylen (PTFE) und innenliegend aus einem Hochtemperatur-Schutzkleber besteht, vorzugsweise FEP.It is also particularly preferably provided that the shrink tubing on the outside of a layer of thermosetting polytetrafluoroethylene (PTFE) and internally consists of a high-temperature protective adhesive, preferably FEP.

Dabei ist auch vorgesehen, dass die Anschlussleitung einen Mantel aus PTFE aufweist. Insbesondere bei der letztgenannten Kombination wird erreicht, dass beim Aufbringen des Schrumpfschlauches durch Temperatureinwirkung nicht nur das Schrumpfen des Schlauches bewirkt wird, sondern der innenliegende Hochtemperaturschmelzkleber (FEP) schmilzt auf und verbindet sich hervorragend mit dem aus PTFE bestehenden Mantel der Anschlussleitung, so dass eine dichte Anordnung erreicht wird.It is also provided that the connection line has a jacket made of PTFE. In particular, in the latter combination is achieved that when applying the shrink tube by temperature not only the shrinkage of the tube is effected, but the internal high-temperature hot melt (FEP) melts and combines well with the existing PTFE sheath of the connecting line, so that a dense Arrangement is achieved.

Ein bevorzugtes Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und im Folgenden näher beschrieben.A preferred embodiment of the invention is illustrated in the drawing and described in more detail below.

Im unbeheizten Endbereich der Heizpatrone 1 kann ein Stift 5 aus Metall vorgesehen sein, der mit dem elektrischen Leiter 3 verbunden ist und über die Mündung der Heizpatrone 1 vorragt, wie in der Zeichnung dargestellt. Anstelle dessen könnte auch der Leiter 3 verlängert sein und über die Mündung der Heizpatrone 1 vorragen, wie dies der Stift 5 zeigt. Der Endbereich oder der Stift 5 kann mit einem metallischen Anschlussstift 6 verbunden sein, der vorzugsweise aus Nickel besteht. Die Verbindung der Elemente 5 und 6 kann durch Schweißung, durch Steckverbindung oder in anderer geeigneter Weise erfolgen.In the drawing, an electric immersion heater 1 is shown, which has a metallic shell 2. This jacket is for example a tube made of stainless steel with a dimension of the order of 2-4mm is common. On the heating cartridge, an electrical conductor 3 is arranged, which is surrounded by an electrically insulating, heat-conducting layer 4, for example MgO. In the unheated end region of the heating cartridge 1, a pin 5 may be provided of metal, which is connected to the electrical conductor 3 and protrudes beyond the mouth of the heating element 1, as shown in the drawing. Instead, the conductor 3 could be extended and protrude beyond the mouth of the heating cartridge 1, as the pin 5 shows. The end portion or the pin 5 can with be connected to a metallic pin 6, which preferably consists of nickel. The connection of the elements 5 and 6 can be effected by welding, by plug connection or in another suitable manner.

Die Anschlussleitung 7 kann eine übliche isolierte Leitung mit innenliegendem Leiter sein. Randseitig ist der Leiter 8 freigelegt, wobei die Anschlussleitung 7 mindestens in dem freigelegten Bereich von einem Gehäuse 9 umgeben ist. Das Gehäuse 9 umgibt zusätzlich eine am freien Ende des Leiters 8 fixierte Kontaktbuchse 10 aus Metall. In diese Kontaktbuchse 10 ist in den Bereich 11 der Anschlussstift 6 einsteckbar oder in der Zeichnung eingesteckt. Das Gehäuse 9 ist in der Montagesolllage mittelbar mit der Heizpatrone 1 lösbar verbunden.The connecting line 7 may be a conventional insulated conductor with internal conductor. The edge 8 of the conductor is exposed, wherein the connecting line 7 is surrounded at least in the exposed area of a housing 9. The housing 9 additionally surrounds a fixed at the free end of the conductor 8 contact socket 10 made of metal. In this contact socket 10, the pin 6 can be inserted or plugged into the area 11 in the drawing. The housing 9 is detachably connected in the assembly target position indirectly with the heating cartridge 1.

Auf die Heizpatrone 1 ist endseitig eine metallische Hülse 12, beispielsweise aus Edelstahl, aufgesteckt und in einem Bereich 13 mit dem Mantel der Heizpatrone 1 formfest und fluiddicht verbunden. In den von der metallischen Hülse 12 umgebenen Hohlraum passt sowohl das Ende der Heizpatrone 1 als auch der Stift 5 beziehungsweise der Anschlussstift 6 hinein. Das Ende des Leiters 3 oder des Stiftes 5 ist mit dem metallischen Anschlussstift 6 innerhalb der Hülse 12 verbunden, wobei der Anschlussstift 6 bis zur der Heizpatrone 1 abgewandten Mündung der Hülse 12 vorragt oder sogar geringfügig über diese hinausragt.On the heating cartridge 1 is a metallic sleeve 12, for example made of stainless steel, plugged and connected in a region 13 with the jacket of the heating element 1 solid and fluid-tight.
