Description
Die Erfindung bezieht sich auf einen Elektromagnet mit einem Magnetkörper, der mit einem Tubusrohr verbunden ist, wobei Mittel zur Befestigung des Magnetkörpers am Tubusrohr vorgesehen sind und der Elektromagnet wenigstens ein einerseits das Tubusrohr, andererseits den Magnetkörper kontaktierendes, elektrisch leitendes Element zur elektrischen Verbindung von Tubusrohr und Magnetkörper aufweisen.The invention relates to an electromagnet with a magnetic body, which is connected to a tube tube, means for fixing the magnetic body are provided on Tubusrohr and the electromagnet at least one on the one hand the Tubusrohr, on the other hand, the magnetic body contacting, electrically conductive element for electrical connection of Tubusrohr and magnetic body.
Elektromagnete mit einem Tubusrohr und einem daran angeordneten Magnetkörper sind bekannt. Zur Verbindung von Magnetkörper und Tubusrohr wird der Magnetkörper auf das Tubusrohr aufgesteckt, aufgeschoben oder aufgepresst und so mehr oder weniger dauerhaft mit dem Tubusrohr verbunden. Das Tubusrohr dient dabei als Führung von einem Magnetanker, der durch Beaufschlagung mit elektrischem Strom bewegbar ist.Electromagnets with a tube tube and a magnetic body arranged thereon are known. To connect the magnetic body and Tubusrohr the magnetic body is attached to the Tubusrohr, postponed or pressed and so more or less durable connected to the Tubusrohr. The tube tube serves as a guide of a magnet armature, which is movable by application of electrical current.
Beispiele für herkömmliche Elektromagnete mit einem Tubusrohr und einem daran angeordneten Magnetkörper sind aus den Dokumenten
Elektromagnete weisen in der Regel einen Schutzleiter auf, der so angebracht wird, dass eine elektrische Verbindung zwischen den metallischen Bestandteilen des Elektromagneten und dem Erdreich hergestellt ist. Besonders wichtig ist hierbei, dass der Schutzleiter alle metallischen Bestandteile des Elektromagneten kontaktiert. Bei herkömmlichen Elektromagneten, die einen auf das Tubusrohr aufgesteckten oder aufgepressten Magnetkörper aufweisen, tritt bei lange anhaltendem Gebrauch, der nicht selten mit Vibrationen einhergeht, eine Trennung der Verbindung zwischen Tubusrohr und Magnetkörper auf. Mit dieser Trennung wird oftmals auch der Schutzleiter unterbrochen, so dass keine ausreichende Erdung des Elektromagneten mehr gegeben ist. Zudem kann, bedingt durch die Tatsache, dass sich der Magnetkörper vom Tubusrohr löst, auch eine Funktionsstörung des Elektromagneten auftreten, die im Dauereinsatz unerwünscht ist und zu Stillstandszeiten sowie zu Reparaturaufwand und damit verbundenen Kosten führt.Electromagnets typically have a protective conductor which is mounted so that an electrical connection between the metallic components of the electromagnet and the soil is made. Particularly important here is that the protective conductor contacts all metallic components of the electromagnet. In conventional electromagnets which have a magnetic body plugged or pressed onto the tube tube, a separation of the connection between the tube tube and the magnetic body occurs during long-term use, which is often accompanied by vibrations. With this separation, the protective conductor is often interrupted so that there is no longer sufficient grounding of the electromagnet. In addition, due to the fact that the magnetic body dissolves from Tubusrohr, also a malfunction of the electromagnet occur, which is undesirable in continuous use and leads to downtime and repair costs and associated costs.
Es ist Aufgabe der vorliegenden Erfindung, einen Elektromagneten mit einem Tubusrohr als Führung für einen Magnetanker und einem Magnetkörper, der mit dem Tubusrohr verbunden ist, zur Verfügung zu stellen, der eine zuverlässige Verbindung zwischen Tubusrohr und Magnetkörper aufweist.It is an object of the present invention, an electromagnet with a tube tube as a guide for a magnet armature and a magnetic body, which is connected to the Tubusrohr to provide, which has a reliable connection between tube tube and magnetic body.
Erfindungsgemäß wird diese Aufgabe durch einen Elektromagneten nach Anspruch 1 gelöst, d.h. dadurch dass ein Elektromagnet zur Verfügung gestellt wird, der ein Tubusrohr als Führung für einen Magnetanker und einen Magnetkörper umfasst. Beim erfindungsgemäßen Elektromagneten ist, wie bereits aus dem Stand der Technik bekannt, der Magnetkörper mit dem Tubusrohr verbunden und wenigstens ein Mittel zur Befestigung des Magnetkörpers am Tubusrohr vorgesehen, wobei der Elektromagnet wenigstens ein einerseits das Tubusrohr und andererseits den Magnetkörper kontaktierendes, elektrisch leitendes Element zur elektrischen Verbindung von Tubusrohr und Magnetkörper aufweist. Über das Mittel kann eine zuverlässige und dauerhafte Verbindung zwischen Tubusrohr und Magnetkörper hergestellt werden. Um hierbei auch sicherzustellen, dass eine Erdung des Elektromagneten, aufgrund eines ununterbrochenen elektrischen Kontakts von Magnetkörper und Tubusrohr gegeben ist und hier Ströme abgeleitet werden können, weist das Mittel wenigstens ein elektrisch leitendes Element zur elektrischen Verbindung von Tubusrohr und Magnetkörper auf. Das elektrisch leitende Element kontaktiert dabei einerseits das Tubusrohr und andererseits den Magnetkörper. Das elektrisch leitende Element kontaktiert dabei metallische Flächen des Tubusrohr beziehungsweise des Magnetkörpers, so dass hier ein Strom ungehindert fließen kann. Das elektrisch leitende Element ist als Scheibe, insbesondere Federscheibe, Wellenscheibe, Lappenscheibe, Zahnscheibe, oder als Ring, insbesondere als Federring, Lappenring, Zahnring oder Sprengring, ausgebildet und die Scheibe oder der Ring weisst am Innen- und/oder Außenumfang angeordnet radiale Ausbrechungen auf, und der zwischen den Ausbrechungen verbleibende Scheiben- oder Ringkörper ist im Wechsel in Richtung des Tubusrohres bzw. des Magnetkörpers gebogen ausgebildet.According to the invention, this object is achieved by an electromagnet according to claim 1, that is, in that an electromagnet is provided which uses a tube tube as Guide for a magnet armature and a magnetic body comprises. In the electromagnet according to the invention, as already known from the prior art, the magnetic body connected to the Tubusrohr and provided at least one means for fixing the magnetic body on Tubusrohr, wherein the electromagnet at least one on the one hand the Tubusrohr and on the other hand, the magnetic body contacting, electrically conductive element having electrical connection of Tubusrohr and magnetic body. By means of a reliable and permanent connection between Tubusrohr and magnetic body can be made. In order to ensure that a grounding of the electromagnet, due to a continuous electrical contact of the magnetic body and Tubusrohr is given and currents can be derived here, the means comprises at least one electrically conductive element for electrically connecting Tubusrohr and magnetic body. The electrically conductive element contacted on the one hand, the Tubusrohr and on the other hand, the magnetic body. The electrically conductive element contacts metallic surfaces of the tube tube or of the magnet body, so that a current can flow unhindered here. The electrically conductive element is formed as a disc, in particular spring washer, wave washer, flap disc, toothed disc, or as a ring, in particular as a spring ring, lobe ring, toothed ring or snap ring, and the disc or the ring knows on the inner and / or outer circumference arranged radial breakouts , And the disc or ring body remaining between the breakouts is formed bent alternately in the direction of the tube tube or the magnet body.
Das im Elektromagneten zum Einsatz kommende Mittel zur Befestigung von Magnetkörper und Tubusrohr beziehungsweise zur Festlegung des Magnetkörpers am Tubusrohr kann als Mutter oder Kappe ausgeführt sein.The means used in the electromagnet for attachment of the magnetic body and Tubusrohr or fixing the magnetic body on Tubusrohr can be used as a mother or cap be executed.
Wird das Mittel als Mutter ausgeführt, so wird diese nach dem Aufstecken oder Aufschieben beziehungsweise Verstemmen des Magnetkörpers mit dem Tubusrohr auf das Tubusrohr, das hierzu günstigerweise ein entsprechendes Gewinde aufweist, aufgeschraubt. Alternativ hierzu besteht auch die Möglichkeit, dass der Magnetkörper ein beispielsweise angesetztes oder eingeformtes Gewinde aufweist, das mit einem entsprechenden Gegengewinde der Mutter in Eingriff gebracht wird. Dabei besteht auch die Möglichkeit, dass an der Mutter ein Gewinde angefügt ist, das somit die Mutter überragt und von einer Oberfläche der Mutter vorsteht und in einer Ausnehmung im Magnetkörper, die beispielsweise das Tubusrohr umschließt, eingeschraubt wird. Es besteht selbstverständlich auch die Möglichkeit, dass insgesamt zwei Gewinde vorgesehen sind, ein radial angeordnetes Gewinde am Tubusrohr und ein axial angeordnetes Gewinde im Magnetkörper und die Mutter entsprechende Gegengewinde aufweist und somit sowohl mit dem Tubusrohr als auch mit dem Magnetkörper verbunden beziehungsweise verschraubt werden kann.If the agent is designed as a nut, then this is screwed after plugging or pushing or caulking of the magnetic body with the Tubusrohr on the Tubusrohr, which conveniently has a corresponding thread for this purpose. Alternatively, there is also the possibility that the magnetic body has an example applied or molded thread, which is brought into engagement with a corresponding mating thread of the nut. In this case, there is also the possibility that a thread is attached to the nut, which thus projects beyond the nut and protrudes from a surface of the nut and in a recess in the magnetic body which encloses, for example, the tube tube is screwed. Of course, there is also the possibility that a total of two threads are provided, a radially arranged thread on Tubusrohr and an axially disposed thread in the magnetic body and the mother has corresponding counter-thread and thus connected to both the tube tube and with the magnetic body or can be screwed.
Die genannten Mittel zur Befestigung erlauben alle eine zuverlässige Verbindung zwischen dem Tubusrohr und dem Magnetkörper und können zudem besonders einfach und damit kostengünstig angeordnet und hergestellt werden.The said means for fixing all allow a reliable connection between the tube tube and the magnetic body and can also be arranged and manufactured particularly simple and therefore cost.
Um eine elektrische Verbindung von Tubusrohr und Magnetkörper sicherzustellen, weist der Elektromagnet ein elektrisch leitendes Element auf, wobei das elektrisch leitende Element mit dem Mittel zur Befestigung verbunden oder in dieses integriert ist. Eine Verbindung oder Integration des elektrisch leitenden Elementes in dem Mittel beziehungsweise mit dem Mittel kann dabei fest oder lösbar ausgebildet werden. Selbstverständlich besteht auch die Möglichkeit, dass eine feste Verbindung zwischen elektrisch leitendem Element und Mittel zur Befestigung erst durch oder beim Aufsetzen, Aufstecken, Aufschrauben oder Aufklemmen des Mittels zur Befestigung auf Tubusrohr beziehungsweise Magnetkörper erstellt wird. Darüber hinaus können die elektrisch leitenden Elemente beziehungsweise das elektrisch leitende Element bereits vorab in dem Mittel zur Befestigung integriert werden und eine elektrisch leitende Aktivierung des Elementes erst beim oder nach dem Aufschrauben, Aufklemmen, Aufsetzen, Aufstecken oder sonstigen Anordnen des Mittels am Tubusrohr beziehungsweise am Magnetkörper durchgeführt werden.In order to ensure an electrical connection of tubular tube and magnetic body, the electromagnet has an electrically conductive element, wherein the electrically conductive element is connected to the means for attachment or integrated in this. A connection or integration of the electrically conductive element in the means or with the means can be formed fixed or detachable. Of course, there is also the possibility that a firm connection between the electrically conductive element and means for attachment only by or when placing, plugging, screwing or clamping the means for attachment to tube tube or magnetic body is created. In addition, the electrically conductive elements or the electrically conductive element can be integrated in advance in the means for attachment and an electrically conductive activation of the element only during or after screwing, clamping, placing, plugging or otherwise arranging the means on Tubusrohr or on the magnetic body be performed.
Als günstig wird in diesem Zusammenhang angesehen, wenn das elektrisch leitende Element als Scheibe ausgebildet ist. Hierbei bieten sich beispielsweise Ausführungen als Federscheibe, Wellenscheibe oder Lappenscheibe an, die zum einen eine Sicherung des Befestigungsmittels und andererseits eine dauerhafte und besonders stabile elektrische Kontaktierung beziehungsweise Verbindung der Magnetelemente gewährleisten können. Die Federscheibe, als eine Ausführungsform der als elektrisch leitendes Element verwendbaren Scheibe wird dabei durch das Anbringen, Aufklemmen, Aufschrauben oder Aufstecken des wie auch immer ausgeführten Mittels zur Befestigung verformt und hierbei einerseits an das Tubusrohr und andererseits an den Magnetkörper angelegt oder angepresst, so dass hier eine elektrische Verbindung gegeben ist. Nach einem ähnlichen Prinzip funktioniert die Verwendung einer Wellen- oder Lappenscheibe, wobei bei letzterer bereits verformte Bereiche vorgesehen sind, die zum einen am Tubusrohr und zum anderen am Magnetkörper angelegt werden können, um hier die elektrische Verbindung dieser Elemente zu verbessern. Neben der Ausführung des elektrisch leitenden Elementes als Scheibe besteht auch die Möglichkeit, dieses als Ring auszuführen, der über das Tubusrohr gesteckt und am Magnetkörper angelegt wird. Auch hier kann allein durch den Ring bereits eine Festlegung des Magnetkörpers am Tubusrohr erfolgen, indem der Ring als Mittel zur Befestigung einerseits und als elektrisch leitendes Element andererseits dient. Der Ring wird dann entweder mit dem Tubusrohr oder mit dem Magnetkörper dauerhaft verbunden, beispielsweise in eine entsprechende Ausnehmung, Nut oder Furche am Tubusrohr oder Magnetkörper eingesetzt und dann mit dem Magnetkörper oder Tubusrohr verstemmt oder verpresst. Hierdurch wird auch sichergestellt, dass das elektrisch leitende Element in Grenzen flexibel bleibt und somit auf Bewegungen des Magnetkörpers am Tubusrohr beziehungsweise Verschiebungen des Tubusrohrs im Magnetkörper reagieren kann, ohne dass die elektrische Verbindung zwischen den Bestandteilen abreißt. Auch kann zur weiteren Verbesserung der elektrischen Verbindung der Ring als Zahnring oder nach Art einer Zahnscheibe ausgebildet sein. Beim Ansetzen, Aufsetzen, Aufstecken, Aufschrauben oder Aufklemmen des Mittels zur Befestigung wird durch den Ring dann eine Beschädigung der Oberfläche des Tubusrohrs oder des Magnetkörpers oder beider Bestandteile durchgeführt, da der Ring beziehungsweise die Scheibe hierzu spezielle zahnartige Vorsprünge trägt. Durch diese Beschädigung der Oberfläche wird die Kontaktfläche zwischen elektrisch leitendem Element und Tubusrohr beziehungsweise Magnetkörper geschaffen oder vergrößert und die elektrische Verbindung dadurch hergestellt oder verbessert.As low is considered in this context, when the electrically conductive element is formed as a disc. in this connection offer, for example, versions as a spring washer, wave washer or disc, on the one hand can ensure a backup of the fastener and on the other hand, a permanent and very stable electrical contact or connection of the magnetic elements. The spring washer, as an embodiment of the usable as an electrically conductive element disc is thereby deformed by attaching, clamping, or attaching the executed whatever means for attachment and this applied on the one hand to the tube tube and on the other hand to the magnetic body or pressed, so that Here is an electrical connection is given. According to a similar principle, the use of a wave or rag wheel works, in the latter already deformed areas are provided, which can be applied to the tube tube on the one hand and the other on the magnetic body, to improve the electrical connection of these elements. In addition to the design of the electrically conductive element as a disk, it is also possible to perform this as a ring, which is inserted over the tube tube and applied to the magnetic body. Here, too, a determination of the magnetic body on the tube tube can already be done by the ring alone by the ring serves as a means for attachment on the one hand and as an electrically conductive element on the other. The ring is then permanently connected to either the tube tube or the magnetic body, for example, inserted into a corresponding recess, groove or groove on Tubusrohr or magnetic body and then caulked or pressed with the magnetic body or Tubusrohr. This also ensures that the electrically conductive element remains flexible within limits and thus can react to movements of the magnetic body on the tube tube or displacements of Tubusrohrs in the magnetic body without the electrical connection between the components breaks off. Also, to further improve the electrical connection of the ring may be formed as a toothed ring or in the manner of a toothed disc. When applying, Placing, plugging, screwing or clamping the means for attachment is then carried out by the ring damage to the surface of Tubusrohrs or the magnetic body or both components, since the ring or the disc carries special tooth-like projections for this purpose. As a result of this damage to the surface, the contact surface between the electrically conductive element and tube tube or magnetic body is created or enlarged, and the electrical connection is thereby produced or improved.
Wenn eine lösbare oder feste Anordnung des elektrisch leitenden Elementes im Mittel zur Befestigung im oder am Tubusrohr und/oder im oder am Magnetkörper vorgesehen ist, so erweist es sich als besonders vorteilhaft, wenn hier eine insbesondere nutförmig ausgebildete Ausnehmung vorgesehen ist, die zum Eingriff des elektrisch leitenden Elementes dient. Diese nutförmige Ausnehmung kann bereits bei der Herstellung des Tubusrohrs des Magnetkörpers oder des Befestigungsmittels in diesem vorgesehen werden oder nachträglich hier eingeschnitten, eingeformt, eingefräst oder in sonstiger Art und Weise eingebracht werden. So besteht beispielsweise die Möglichkeit, dass das Mittel zur Befestigung aus einem Kunststoff gebildet wird. Hierbei kann bereits bei der Herstellung, die beispielsweise in einem Spritzgussverfahren erfolgt, eine entsprechende Ausnehmung in das Werkstück integriert oder eingeplant beziehungsweise eingeformt werden. Bei dem Tubusrohr, das ebenfalls aus einem Kunststoffmaterial gebildet werden kann, kann die Ausnehmung beziehungsweise Vertiefung oder Nut auch bereits im Herstellungsprozess in das Werkstück eingebracht werden. Hier besteht jedoch selbstverständlich auch die Möglichkeit, dass eine nachträgliche Einbringung der Ausnehmung erfolgt.If a detachable or fixed arrangement of the electrically conductive element is provided in the means for attachment in or on the tube tube and / or in or on the magnetic body, then it proves to be particularly advantageous if here a particular groove-shaped recess is provided, which is for engaging the electrically conductive element is used. This groove-shaped recess can already be provided in the manufacture of the tube tube of the magnetic body or the fastening means in this or subsequently cut here, molded, milled or introduced in any other way. For example, there is the possibility that the means for attachment is formed from a plastic. In this case, a corresponding recess can already be integrated into the workpiece during the production, which takes place, for example, in an injection molding process, or can be planned in or molded into it. In the tube tube, which can also be formed from a plastic material, the recess or recess or groove can also be introduced into the workpiece during the manufacturing process. Of course, there is also the possibility here that a subsequent introduction of the recess takes place.
Eine bevorzugte Ausführungsform der Erfindung sieht vor, dass das elektrisch leitende Element lösbar oder fest an oder in dem Mittel zur Befestigung beziehungsweise an dem Tubusrohr oder an dem Magnetkörper angeordnet ist. Dies bedeutet, dass das elektrisch leitende Element an einem der genannten Bestandteile des Elektromagneten vorgesehen ist und eine elektrische Verbindung nach dem Aufsetzen, Ansetzen, Aufschrauben, Aufstecken oder sonstigen Verbinden von Tubusrohr und Magnetkörper und/oder dem Festlegen des Mittels zur Befestigung durchgeführt wird. Um hier eine lösbare oder feste Verbindung von elektrisch leitendem Element und Mittel zur Befestigung beziehungsweise Tubusrohr oder Magnetkörper durchführen zu können, empfiehlt sich insbesondere eine Anordnung durch Ankleben, Anschmelzen, Anlöten, Anschweißen oder dem formschlüssigen Ein- oder Ansetzen des Elementes. Eine weitere Möglichkeit besteht im Einstemmen, also dem Herstellen einer mechanischen Verbindung. Wird das Mittel zur Befestigung, der Magnetkörper oder das Tubusrohr aus einem elektrisch nicht leitenden Material hergestellt beziehungsweise weist dieses Bereiche auf, die elektrisch nicht leitend ausgebildet sind, so sieht eine bevorzugte Ausführungsform der Erfindung vor, dass das elektrisch leitende Element in das Mittel zur Befestigung, den Magnetkörper oder das Tubusrohr beziehungsweise in Bereichen davon eingeformt vorliegt, so dass hier dennoch eine ausreichende und zuverlässige sowie sichere elektrische Kontaktierung stattfinden kann. Es besteht hier zur Einformung des elektrisch leitenden Elements die Möglichkeit, dieses beispielsweise beim Herstellungprozess des Befestigungsmittels des Magnetkörpers oder des Tubusrohrs mit in den Werkstückrohling einzuspritzen. Wird hier eine Gießform verwendet, so kann das elektrisch leitende Element selbstverständlich auch mit der Vergussmasse umgossen werden, um hierbei in das Mittel zur Befestigung, den Magnetkörper oder das Tubusrohr eingeformt zu werden. Auch besteht selbstverständlich die Möglichkeit der nachträglichen Anordnung des elektrisch leitenden Elements, indem dieses in das Mittel zur Befestigung, den Magnetkörper oder das Tubusrohr eingeschmolzen wird. Das Einschmelzen kann dabei in besonders einfacher Art und Weise dadurch erfolgen, dass das elektrisch leitende Element elektrisch beaufschlagt wird und sich dabei erhitzt. Hierüber kann gleichzeitig eine Funktionskontrolle des elektrisch leitenden Elementes durchgeführt werden.A preferred embodiment of the invention provides that the electrically conductive element releasably or firmly on or in the means for attachment or on the tube tube or on the magnetic body is arranged. This means that the electrically conductive element is provided on one of said components of the electromagnet and an electrical connection is made after placing, attaching, screwing, plugging or otherwise connecting the tube tube and magnetic body and / or fixing the means for fastening. In order to perform a detachable or fixed connection of electrically conductive element and means for attachment or tube tube or magnetic body here, in particular, an arrangement by gluing, melting, soldering, welding or the positive insertion or attachment of the element is particularly recommended. Another possibility is in the caulking, so the establishment of a mechanical connection. If the means for fastening, the magnetic body or the tube tube made of an electrically non-conductive material or has this areas, which are electrically non-conductive, so provides a preferred embodiment of the invention, that the electrically conductive element in the means for attachment , the magnet body or the tube tube or is formed in areas thereof, so that here nevertheless a sufficient and reliable and secure electrical contact can take place. Here, for the purpose of forming the electrically conductive element, it is possible to inject it into the workpiece blank, for example during the production process of the fastening means of the magnetic body or of the tube tube. If a casting mold is used here, the electrically conductive element can, of course, also be encapsulated with the potting compound in order to be molded into the means for fastening, the magnetic body or the tube tube. Of course, there is also the possibility of subsequent arrangement of the electrically conductive element by this is melted into the means for attachment, the magnetic body or the tube tube. The melting can in a particularly simple way and The way in which the electrically conductive element is electrically charged and thereby heated. This can be carried out at the same time a functional check of the electrically conductive element.
Wie bereits vorher ausgeführt, wird das elektrisch leitende Element als verformbare Scheibe oder verformbarer Ring ausgebildet. Daneben besteht auch die Möglichkeit, dass das elektrisch leitende Element in sonstiger Weise ausgeführt wird und hierbei auch verform- oder verspannbar ausgebildet ist. Eine Kontaktierung von Magnetkörper und Tubusrohr erfolgt dann nach Verformen oder Verspannen des elektrisch leitenden Elementes. Im Zuge des Verformens oder Verspannens des elektrisch leitenden Elementes kann auch ein Eingriff des elektrisch leitenden Elementes in den Magnetkörper und/oder das Tubusrohr stattfinden, so dass hier entweder erst durch den Eingriff ein elektrischer Kontakt zu einer elektrischen Verbindung hergestellt wird oder aber durch den Eingriff die bereits bestehende elektrische Kontaktierung weiter verbessert und stabilisiert wird. Die Herstellung der elektrischen Verbindung sowie der Eingriff des elektrisch leitenden Elementes in den Magnetkörper und/oder das Tubusrohr kann dabei vor, während oder nach dem Verformen oder Verspannen vorgesehen sein. Dies bedeutet, dass das elektrisch leitende Element zunächst lose, das heißt im Laufsitz oder Gleitsitz auf das Tubusrohr oder den Magnetkörper aufgesetzt oder aufgebracht wird und dann, im Zuge eines Verformungs- oder Verspannungsprozesses eine Festlegung des elektrisch leitenden Elementes erfolgt. Im Zuge des Verformens oder des Verspannens des elektrisch leitenden Elementes kommt es dann zur Herstellung oder Ausbildung eines elektrischen Kontakts beziehungsweise zu dessen Verbesserung und Stabilisierung.As stated previously, the electrically conductive element is formed as a deformable disk or deformable ring. In addition, there is also the possibility that the electrically conductive element is executed in any other way and in this case is formed deformable or braced. A contacting of the magnetic body and Tubusrohr then takes place after deformation or distortion of the electrically conductive element. In the course of deformation or distortion of the electrically conductive element, an engagement of the electrically conductive element in the magnetic body and / or the tube tube take place, so that here either by the engagement of an electrical contact to an electrical connection is made or by the intervention the existing electrical contact is further improved and stabilized. The preparation of the electrical connection and the engagement of the electrically conductive element in the magnetic body and / or the tube tube can be provided before, during or after the deformation or distortion. This means that the electrically conductive element is first loosely, that is placed or applied to the barrel tube or the magnetic body in the running seat or sliding fit and then, in the course of a deformation or bracing process, a determination of the electrically conductive element. In the course of deforming or straining the electrically conductive element, it then comes to the production or training of an electrical contact or to its improvement and stabilization.
Das elektrisch leitende Element ist in einer bevorzugten Ausführungsform der Erfindung so ausgeführt, dass eine radiale oder axiale Kontaktierung des Magnetkörpers erfolgt, wobei auch andererseits eine axiale und/oder radiale Kontaktierung des Tubusrohrs stattfindet. Selbstverständlich besteht auch die Möglichkeit, dass das elektrisch leitende Element eines der Bestandteile, das heißt den Magnetkörper oder das Tubusrohr radial kontaktiert und das den zweiten Bestandteil, das heißt, den Magnetkörper oder das Tubusrohr andererseits axial kontaktiert. Eine axiale und radiale Kontaktierung beispielsweise des Tubusrohrs kann dadurch erreicht werden, dass in diesem eine umlaufende Ringnut vorgesehen ist, indem ein Teilbereich des elektrisch leitenden Elements eingreift und ein weiterer Bereich des elektrisch leitenden Elementes dann in axialer Richtung an dem Tubusrohr oberflächenparallel beziehungsweise umfangsparallel anliegt. Bezüglich des Magnetkörpers besteht auch die Möglichkeit, dass ein Bereich des elektrisch leitenden Elementes auf einer ersten Oberfläche des Magnetkörpers aufliegt und sich radial in diese Oberfläche erstreckt, während ein zweiter Bereich koaxial zum Magnetkörper angeordnet ist und an einer weiteren Oberfläche des Magnetkörpers axial anliegt.The electrically conductive element is designed in a preferred embodiment of the invention so that a radial or axial contacting of the magnetic body takes place, wherein also on the other hand takes place an axial and / or radial contacting of the Tubusrohrs. Of course, there is also the possibility that the electrically conductive element of one of the components, that is, the magnetic body or the Tubusrohr radially contacted and the other part, that is, the magnetic body or the Tubusrohr axially contacted on the other hand. Axial and radial contacting, for example, of the tube tube can be achieved by providing a circumferential annular groove therein by engaging a portion of the electrically conductive element and then abutting a further region of the electrically conductive element in the axial direction on the tube tube in parallel to the surface or parallel to the circumference. With respect to the magnetic body, there is also the possibility that a region of the electrically conductive element rests on a first surface of the magnetic body and extends radially into this surface, while a second region is arranged coaxially to the magnetic body and abuts axially on a further surface of the magnetic body.
Erfindungsgemäß ist auch vorgesehen, dass das als Scheibe oder Ring ausgebildete elektrisch leitende Element beziehungsweise das Mittel zur Befestigung Schneiden, Grate oder Schnittkanten aufweist, und somit eine Kontaktierungsfläche an dem Magnetkörper und dem Tubusrohr beim Einsetzen, Ansetzen, Aufsetzen, Aufklemmen, Verspannen oder Verstemmen selbständig herstellt.According to the invention it is also provided that the trained as a disc or ring electrically conductive element or the means for attachment cutting, ridges or cut edges, and thus a contacting surface on the magnetic body and the tube tube when inserting, attaching, placing, clamping, bracing or caulking independently manufactures.
Hierbei ist vorgesehen, dass die Schneiden durch Schnittkanten in das Material des Magnetkörpers und/oder des Tubusrohres eingreifen, und hier eine Oberflächenschicht abtragen und dauerhaft im Material des Magnetkörpers bzw. des Tubusrohres festgelegt werden. Das elektrisch leitende Element wird dabei beispielsweise mit dem Magnetkörper und dem Tubusrohr verzahnt bzw. krallt sich in diesem fest und reißt dabei bereichsweise die Oberfläche des Tubusrohres und/oder des Magnetkörpers auf, wobei eine blanke Kontaktfläche geschaffen oder vergrößert und die dauerhafte Leitfähigkeit gesichert wird.In this case, it is provided that the cutting edges engage in the material of the magnetic body and / or the tube tube by cutting edges, and here ablate a surface layer and are permanently fixed in the material of the magnetic body or of the tube tube. The electrically conductive element is interlocked, for example, with the magnetic body and the Tubusrohr or clings in this firmly and thereby partially ruptures the surface of the Tubusrohres and / or the magnetic body, wherein creating or enlarging a bare contact surface and ensuring permanent conductivity.
Im Interesse einer Materialersparnis bei der Herstellung des elektrisch leitenden Elementes kann die Ringstärke bzw. die Scheibendicke weitgehend reduziert werden, so dass diese nur wenige Millimeter bis Zehntel-Millimeter misst. Die Scheibe oder der Ring können auch als Folie ausgebildet werden. Erfindungsgemäss weist die Scheibe oder der Ring am Innen- beziehungsweise Außenumfang angeordnete radiale Ausbrechungen auf. Die Ausbrechungen sind dann als materialfreier Raum der Scheibe oder des Rings zu verstehen. Zwischen den Ausbrechungen verbleiben Reste des Scheiben- oder Ringkörpers, so dass die Scheibe oder der Ring letztlich nach Art eines Zahnringes mit Vorsprüngen am Außen- sowie Innenumfang ausgebildet ist. Um nun eine zuverlässige und stabile elektrische Verbindung zwischen dem Tubusrohr und dem Magnetkörper sicherstellen zu können, sind die verbleibenden Reste des Ringkörpers im Wechsel in Richtung des Tubusrohrs bzw. des Magnetkörpers gebogen und kontaktieren einerseits das Tubusrohr sowie andererseits den Magnetkörper.In the interest of saving material in the production of the electrically conductive element, the ring thickness or the thickness of the pane can be largely reduced so that it measures only a few millimeters to tenths of a millimeter. The disc or the ring can also be formed as a film. According to the invention, the disk or the ring on the inner or outer circumference arranged on radial Ausbrechungen. The breaks are then to be understood as a material-free space of the disc or ring. Remains of the disk or ring body remain between the breaks, so that the disc or the ring is ultimately formed in the manner of a toothed ring with projections on the outer and inner circumference. In order to be able to ensure a reliable and stable electrical connection between the tube tube and the magnet body, the remaining remnants of the annular body are alternately bent in the direction of the tube tube or the magnetic body and contact on the one hand the tube tube and on the other hand the magnetic body.
Da das elektrisch leitende Element dauernd stromführend ausgebildet ist, besteht hier die Möglichkeit, dass sich Korossion bildet. Um dies zu verhindern, sieht eine bevorzugte Ausführungsform des erfindungsgemäßen Elektromagneten vor, dass wenigstens eine das elektrisch leitende Element einschließende Dichtung vorgesehen ist. Das elektrisch leitende Element kann dabei beispielsweise zwischen wenigstens zwei in axialer Richtung des Tubusrohrs angeordneten Dichtelementen angeordnet werden. Beim Zusammenbau bzw. bei der Bildung des Elektromagneten wird zunächst der Magnetkörper auf das Tubusrohr aufgeschoben oder aufgesteckt und an diesem bereits im Laufsitz oder Presssitz festgelegt. Als nächstes wird eine erste Dichtung, beispielsweise ein Dichtring oder eine Dichtlippe oder Dichtscheibe, auf das Tubusrohr aufgeschoben, wonach dann das Aufsetzen, Aufschieben, Aufstemmen, Aufklemmen oder Aufschrauben des elektrisch leitenden Elements erfolgt. Hernach wird eine zweite Dichtung, diese kann wiederum als Scheibe, Ring, Lippe oder in sonstiger geeignet erscheinender Art und Weise ausgebildet sein, auf das Tubusrohr aufgeschoben, womit das elektrisch leitende Element zwischen zwei in axialer Richtung des Tubusrohr angeordneter Dichtelemente angeordnet wird. Alternativ oder zusätzlich besteht selbstverständlich auch die Möglichkeit, dass das elektrisch leitende Element in die Dichtung eingeformt oder eingespritzt ist, das heißt, im wesentlichen in die Dichtung integriert vorliegt. Hierbei kann eine vollständige Umschließung des elektrisch leitenden Elementes durch das Material der Dichtung bzw. durch die Dichtung selbst vorgesehen werden. Ist dies der Fall, so durchbricht das elektrisch leitende Element die Dichtung wenigstens abschnittsweise in radialer und axialer Richtung und kontaktiert das Tubusrohr und den Magnetkörper. Bevorzugt erfolgt ein Durchbrechen oder Durchstoßen der Dichtung erst beim Verformen oder Verspannen des elektrisch leitenden Elements. Hierbei ist vorgesehen, dass das elektrisch leitende Element vollständig von Dichtmaterial umgeben ist und so beispielsweise in nicht verbautem Zustand Form und Aussehen eines Dichtrings oder einer Dichtscheibe aufweist. Nach dem Aufsetzen des Elements auf dem Tubusrohr beziehungsweise nach Anordnen im Mittel zur Befestigung und nach dem Festlegen im erfindungsgemäßen Elektromagneten wird im Zuge der Festlegung das Dichtmaterial von dem im Inneren angeordneten elektrisch leitenden Element wenigstens abschnittsweise sowohl radial als auch axial durchbrochen und somit eine Kontaktierung des Tubusrohrs und des Magnetkörpers hergestellt. Um hier eine zufriedenstellende Durchbrechung vorzunehmen, weist das elektrisch leitende Element günstigerweise entsprechende Schneiden, Grate oder Vorsprünge auf, die in der Lage sind, durch das elastische Material der Dichtung zu dringen. Es besteht auch die Möglichkeit, dass auf den Oberflächen der Scheibe oder des Rings ein Dichtmaterial aufgeklebt, aufgespritzt, aufgeschweißt oder in sonstiger Art und Weise angeordnet wird und so das elektrisch leitende Element bereits mit Dichtungen versehen im Elektromagneten angeordnet werden kann. Auch hier besteht die Möglichkeit, dass das elektrisch leitende Element die Dichtung nur bereichsweise durchbricht und so eine nur bereichsweise elektrische Kontaktierung über das elektrisch leitende Element durchgeführt wird. Eine bevorzugte Ausführungsform des im erfindungsgemäßen Elektromagneten einsetzbaren elektrisch leitenden Elementes sieht vor, dass das elektrisch leitende Element Eingriffsmittel, und hier beispielsweise Schneiden, vorspringende Grate oder Schnittkanten aufweist, die eine Verletzung der Oberfläche des Magnetkörpers und/oder des Tubusrohres durchführen, um hier die elektrische Kontaktierung herzustellen beziehungsweise zu verbessern. Aufgrund dieses Eingriffes in die Oberfläche des Magnetkörpers beziehungsweise des Tubusrohres wird jedoch eine korrosionsschützende Oxidschicht, die sich bei entsprechender Behandlung auf den Oberflächen bildet, verletzt beziehungsweise entfernt, so dass sich hier insbesondere an den Angriffspunkten beziehungsweise den Kontaktflächen der Schneiden, Grate oder Schnittkanten Korrosionspunkte bilden. Um einen praktisch luftdichten Abschluss des elektrisch leitenden Elementes gegenüber der umgebenden Atmosphäre zu erreichen, ist in einer bevorzugten Ausführungsform des Elektromagneten die Anordnung von Dichtungen im Mittel zur Befestigung vorgesehen, wobei die hier angeordneten Dichtungen vom elektrisch leitenden Element beabstandet angebracht sind. Vorgesehen ist hierbei eine erste Dichtung, die axial am Tubusrohr anliegt und eine zweite Dichtung, die radial am Magnetkörper abdichtet. Zwischen diesen beiden Dichtungen, die beispielsweise in entsprechenden Ausnehmungen oder Nuten im Mittel zur Befestigung eingelegt oder eingebracht, beispielsweise eingespritzt oder eingeformt sein können, befindet sich dann das elektrisch leitende Element und wird durch die Dichtungen, die beispielsweise als Dichtring, Dichtstreifen, Dichtmasse oder Dichtband ausgebildet sein können, gegenüber eindringender Feuchtigkeit geschützt. Die Dichtungen sind im Mittel zur Befestigung beabstandet zum elektrisch leitenden Element angeordnet, so dass hier zu keiner Zeit die Gefahr besteht, dass eine Verletzung der Dichtungen durch das teilweise scharfkantig ausgebildete elektrisch leitende Element erfolgt. Günstigerweise sind die mit dem erfindungsgemäßen Elektromagneten verwendbaren Dichtungen als O-Ringe, Dichtbänder, Dichtlippen oder Dichtscheiben ausgebildet. Bei der - wie oben bereits genannten Anordnung von zwei Dichtungen ober- und unterseits des elektrisch leitenden Elements - besteht auch die Möglichkeit, dass wenigstens zwei Dichtungen einen Kontaktraum am Tubusrohr oder im Magnetkörper bilden, in dem das elektrisch leitende Element angeordnet ist. Die Dichtungen begrenzen dann den Kontaktraum nach zwei Seiten hin. Die Dichtungen müssen dem elektrisch leitenden Element auch nicht unmittelbar am Elektromagneten, das heißt am Tubusrohr und/oder am Magnetkörper zugeordnet angeordnet sein. Wichtig ist, dass die Dichtungen das Eindringen von Flüssigkeit oder von Luft verhindern, so dass keine Korrosion des elektrisch leitenden Elementes stattfinden kann.Since the electrically conductive element is designed to be permanently current-carrying, there is the possibility here that corosion forms. In order to prevent this, a preferred embodiment of the electromagnet according to the invention provides that at least one seal enclosing the electrically conductive element is provided. The electrically conductive element can be arranged, for example, between at least two arranged in the axial direction of the tube tube sealing elements. When assembling or during the formation of the electromagnet, the magnet body is first pushed onto the tube tube or plugged on and fixed to it already in the running seat or press fit. When Next, a first seal, for example, a sealing ring or a sealing lip or gasket, is pushed onto the tube tube, after which then placing, pushing, chiselling, clamping or screwing the electrically conductive element takes place. Thereafter, a second seal, which in turn may be formed as a disc, ring, lip or in any other suitable manner, pushed onto the tube tube, whereby the electrically conductive element between two arranged in the axial direction of the tube tube sealing elements is arranged. Alternatively or additionally, of course, there is also the possibility that the electrically conductive element is molded or injected into the seal, that is, is substantially integrated in the seal. In this case, a complete enclosure of the electrically conductive element can be provided by the material of the seal or by the seal itself. If this is the case, then the electrically conductive element breaks through the seal at least in sections in the radial and axial direction and contacts the tube tube and the magnet body. Preferably, a breakthrough or puncturing of the seal takes place only during deformation or distortion of the electrically conductive element. In this case, it is provided that the electrically conductive element is completely surrounded by sealing material and thus has the form and appearance of a sealing ring or a sealing disc, for example, in an uninstalled state. After placement of the element on the Tubusrohr or after arranging in the means for attachment and after setting in the electromagnet according to the invention, the sealing material is at least partially broken both radially and axially in the course of fixing the electrically conductive element arranged in the interior and thus a contact of the Tubusrohrs and the magnetic body produced. In order to make a satisfactory opening here, the electrically conductive element conveniently has corresponding cutting edges, ridges or protrusions which are capable of the elastic material of the seal to penetrate. There is also the possibility that a sealing material is glued, sprayed, welded or otherwise arranged on the surfaces of the disc or ring and so the electrically conductive element already provided with seals in the electromagnet can be arranged. Again, there is the possibility that the electrically conductive element breaks through the seal only partially and so only a partial electrical contact is made via the electrically conductive element. A preferred embodiment of the insertable in the electromagnet according to the invention electrically conductive element provides that the electrically conductive element engaging means, and here, for example, cutting, protruding ridges or cut edges, which perform a violation of the surface of the magnetic body and / or Tubusrohres here to the electrical Establish contact or improve. Due to this engagement in the surface of the magnetic body or of the tubular tube, however, a corrosion-protecting oxide layer which forms with appropriate treatment on the surfaces is injured or removed, so that corrosion points form here, in particular at the points of contact or the contact surfaces of the cutting edges, ridges or cut edges , In order to achieve a practically airtight seal of the electrically conductive element relative to the surrounding atmosphere, in a preferred embodiment of the electromagnet, the arrangement of seals is provided in the means for attachment, wherein the seals arranged here are spaced from the electrically conductive element. Provided here is a first seal which rests axially on the tube tube and a second seal which seals radially on the magnetic body. Between these two seals, which may be inserted or introduced, for example, injected or molded, for example, in corresponding recesses or grooves in the means for attachment, is then the electrically conductive element and is protected from penetrating moisture by the seals, which may be formed, for example, as a sealing ring, sealing strip, sealant or sealing tape. The seals are arranged spaced apart from the means for fixing the electrically conductive element, so that there is at no time the risk that a violation of the seals by the partially sharp-edged electrically conductive element takes place. Conveniently, the seals used with the electromagnet according to the invention are designed as O-rings, sealing strips, sealing lips or sealing washers. In the - as mentioned above arrangement of two seals above and below the electrically conductive element - there is also the possibility that at least two seals form a contact space on Tubusrohr or in the magnetic body in which the electrically conductive element is arranged. The seals then limit the contact space to two sides. The seals must also not be arranged directly on the electromagnet, that is to say on the tube tube and / or on the magnet body, to the electrically conductive element. It is important that the seals prevent the ingress of liquid or air, so that no corrosion of the electrically conductive element can take place.
Es besteht auch die Möglichkeit, dass das elektrisch leitende Element als sogenannter Leitgummi ausgeführt wird. Dieser Leitgummi besteht dann aus mit Kohlenstoffpartikeln gefülltem oder versetztem Gummimaterial. Das Verwenden eines Leitgummis bietet den Vorteil, dass hier eine elastische Dauerverbindung durchgeführt werden kann, die auch bei Vibration, wie diese an Elektromagneten auftritt, eine stabile und dauerhafte elektrische Verbindung zwischen Tubusrohr und Magnetkörper sicherstellen kann. Zudem übernimmt der Dichtgummi auch eine Abdichtfunktion für die Verbindungsstelle beziehungsweise -fläche von Tubusrohr und Magnetkörper.There is also the possibility that the electrically conductive element is designed as a so-called conductive rubber. This conductive rubber then consists of carbon particles filled or offset rubber material. The use of a conductive rubber has the advantage that an elastic permanent connection can be carried out here, which can ensure a stable and permanent electrical connection between tube tube and magnet body even with vibration, as occurs at electromagnets. In addition, the sealing rubber also assumes a sealing function for the connection point or area of tube tube and magnet body.
Als empfehlenswert wird auch angesehen, wenn eine unmittelbar am oder im elektrisch leitenden Element angeordnete zusätzliche Dichtung vorgesehen ist. Diese Dichtung kann dann dafür verwendet werden, das elektrisch leitende Element mit dem Mittel zur Befestigung zu befestigen, zu verbinden oder zu verspannen und gleichzeitig abzudichten. Dies erfolgt dadurch, dass sich in einer Verbindung von elektrisch leitendem Element und Mittel zur Befestigung das Dichtelement verformt und im Zuge dieser Verformung eine Verformung des elektrisch leitenden Elements durchgeführt wird, wobei dieses in das Mittel zur Befestigung eingepresst oder dauerhaft eingesetzt und festgelegt wird. Auch hier, wie bei allen anderen verwendeten Dichtungen, besteht die Möglichkeit, diese ganz oder teilweise aus Leitgummi zu bilden.It is also considered to be recommendable if an additional seal arranged directly on or in the electrically conductive element is provided. This seal can then be used to secure, connect or clamp the electrically conductive element with the means for attachment and at the same time seal. This is done by deforming the sealing element in a connection of the electrically conductive element and the fastening means and, in the course of this deformation, carrying out a deformation of the electrically conductive element, which is pressed into the fastening means or permanently inserted and fixed. Again, as with all other seals used, it is possible to form these wholly or partly of conductive rubber.
Bevorzugt umfasst der Elektromagnet der vorliegenden Erfindung ein das Tubusrohr und den Magnetkörper umschließendes Gehäuse. Um hier eine Kontaktierung des Tubusrohrs und des Magnetkörpers sicherzustellen, besteht einerseits die Möglichkeit, das elektrisch leitende Element in das Gehäuse einzufügen und über das Mittel zur Befestigung eine Festlegung von Tubusrohr, Gehäuse und Magnetkörper durchzuführen. Im Zuge dieser Festlegung erfolgt dann die elektrische Kontaktierung beziehungsweise Verbindung von Magnetkörper und Tubusrohr. Darüber hinaus besteht auch die Möglichkeit, das elektrisch leitende Element so auszubilden, dass eine elektrische Verbindung von Gehäuse, Magnetkörper und Tubusrohr über das elektrisch leitende Element stattfinden kann. Hierbei ist die Verwendung aller vorgenannter Ausführungsformen des elektrisch leitenden Elements beziehungsweise des Mittels zur Befestigung möglich, wobei lediglich noch das Gehäuse von diesen Bestandteilen des Elektromagneten mit umfasst beziehungsweise mit festgelegt oder kontaktiert wird.Preferably, the electromagnet of the present invention comprises a housing enclosing the tube tube and the magnetic body. In order to ensure a contacting of the Tubusrohrs and the magnetic body, on the one hand there is the possibility to insert the electrically conductive element into the housing and perform on the means for fixing a determination of Tubusrohr, housing and magnetic body. In the course of this determination is then made the electrical contact or connection of the magnetic body and Tubusrohr. In addition, it is also possible, the electrically conductive element in such a way that an electrical connection of housing, magnetic body and Tubusrohr can take place via the electrically conductive element. Here, the use of all the aforementioned embodiments of the electrically conductive element or the means for attachment is possible, wherein only the housing of these components of the electromagnet is also included or fixed with or contacted.
Der erfindungsgemäße Elektromagnet eignet sich bevorzugt für eine Betriebsspannung im Niederspannungsbereich, das heißt, zwischen 12 V und 400 V wird. Als günstig wird angesehen, wenn eine Spannung zwischen 12 V und 230 V, zwischen 12 V und 48 V oder zwischen 12 V und 35 V am Elektromagneten anliegt. Selbstverständlich besteht die Möglichkeit, auch Betriebsspannungen die höher oder niedriger liegen, das heißt in einem Bereich unter 12 V beziehungsweise über 400 V am Elektromagneten anzulegen. Das elektrisch leitende Element muss dann so ausgebildet sein, dass auch diese Spannungen aufgenommen werden können.The electromagnet according to the invention is preferably suitable for an operating voltage in the low-voltage range, that is, between 12 V and 400 V. It is considered favorable when a voltage between 12 V and 230 V, between 12 V and 48 V or between 12 V and 35 V is applied to the electromagnet. Of course, it is also possible to apply operating voltages which are higher or lower, that is to say in a range below 12 V or above 400 V at the electromagnet. The electrically conductive element must then be designed so that these voltages can be absorbed.
Es versteht sich, dass die vorstehend genannten und nachstehend noch zu erläuternden Merkmale nicht nur in der jeweiligen angegebenen Kombination sondern auch in anderen Kombinationen denkbar und verwend- beziehungsweise einsetzbar sind, sofern unter den Schutzumfang von Anspruch 1 fallend.It is understood that the features mentioned above and below are not only conceivable and useable or usable in the respective combination indicated but also in other combinations, if covered by the scope of claim 1.

Selbstverständlich besteht auch die Möglichkeit, dass keine Befestigungsmutter 20 verwendet wird, um die Verbindung zwischen Magnetkörper 12 und Tubusrohr 11 zu sichern beziehungsweise zu verbessern. Vielmehr kann stattdessen auch das elektrisch leitende Element 17 als Verbindungsmittel ausgebildet sein. Das elektrisch leitende Element 17 ist dann als Scheibe oder Ring ausgebildet. In dieser Ausführungsform, das heißt in der Ausführungsform ohne Befestigungsmutter 20, wird das elektrisch leitende Element 17 beispielsweise als Ring ausgebildet, der einen Vorsprung zum Eingriff in das Tubusrohr 11 aufweist.

Das somit am Tubusrohr 11 festgelegte elektrisch leitende Element 17 wird hernach in Richtung des Magnetkörpers 12 verbogen oder in sonstiger Weise verformt und dabei an der Oberfläche 19 des Magnetkörpers 12 angelegt. Nach einer abschließenden Verpressung oder Verstemmung des elektrisch leitenden Elementes 17 wird eine dauerhafte und belastbare Verbindung von Tubusrohr 11 und Magnetkörper 12 durchgeführt.
