Abstract

According to the subject matter of the invention, a process for inserting a plastics body into an opening of a sensor housing is provided, wherein the opening has a side surface with an edge, in which a collar-like bead is formed on the edge and a shoulder-like protrusion for supporting the plastics body is formed on the side surface, a strip-like seal is incorporated on the protrusion before the plastics body is placed thereon, the plastics body is placed onto the protrusion of the side surface in such a manner that a side surface of the plastics body is arranged alongside the side surface of the sensor housing such that they impact against one another, and a form-fitting, elastically supported bond is produced by means of deformation between at least one part of the side surface of the sensor housing and a part of the side surface of the plastics body, such as to form a substantially jointless and substantially step-free transition between the sensor housing and the plastics body at the bonding site on the top side of the sensor housing and of the plastics body.

Sensorgehäuse sensor housing
Die Erfindung betrifft ein Verfahren zum Einfügen eines Kunststoffkörpers gemäß dem Oberbegriff des Patentanspruchs 1 und ein Sensorgehäuse gemäß dem Oberbegriff des Patentanspruchs 7. The invention relates to a method for inserting a plastic body according to the preamble of patent claim 1 and a sensor housing according to the preamble of patent claim 7.
Das Einfügen von Kunststoffen in ein Metallgehäuse ist in der Technik ein wichtiger Bestandteil, insbesondere in Bereichen in denen eine optische Kon¬ trolle von Fertigungsprozessen notwendig ist. Im Bereich der Lebensmitteltechnik werden an derartige Verbindungen oftmals erhöhte Anforderungen an die physikalischen und chemischen Eigenschaften gestellt, insbesondere muss eine derartiger Verbund hohe Anforderungen hinsichtlich der Zuverlässigkeit, der Dichtheit erfüllen und die entsprechenden Normen einhalten. Weiterhin unterliegen derartige Verbindungen stark wechselnden Temperaturen im Bereich von -40°C bis 120°C und unterliegen Druckschwankungen im Bereich von mehreren Bar. Um diese hohen Anforderungen erfüllen zu können, werden bei herkömmlichen Verfahren die Verbindungsstellen zwischen dem Gehäuse und des Kunststoffkörpers mittels mechanischen Befestigungsmitteln, wie Schrauben und Klammern, und oder chemischen Dichtungsmitteln zumeist in Form von Klebemittel geschützt. Nachteilig ist jedoch, dass die zwischen den Dichtflächen der aneinanderliegenden Seitenflächen des Gehäuserandes und des Kunststoffkörpers eingebrachten Klebemittel und oder Dichtmittel unerwünschte Inhaltstoffe enthalten, die eventuell abgegeben werden und nicht ausreichend alterungsbeständig sind. Andererseits sind mechanische Befestigungsmittel aufwändig in der Herstellung und verursachen vielfältige hygienische Nachteile, insbesondere bei der Reinigung. The insertion of plastics in a metal housing is an important component in the art, particularly in areas in which an optical Kon ¬ troll of manufacturing processes is necessary. In the field of food technology, such compounds are often subject to increased demands on the physical and chemical properties; in particular, such a composite must fulfill high requirements with regard to reliability, tightness and comply with the corresponding standards. Furthermore, such compounds are subject to strongly changing temperatures in the range of -40 ° C to 120 ° C and are subject to pressure fluctuations in the range of several bar. In order to meet these high requirements, in conventional methods, the connection points between the housing and the plastic body by means of mechanical fasteners such as screws and clips, and or chemical sealants, mostly in the form of adhesives. The disadvantage, however, that the introduced between the sealing surfaces of the adjacent side surfaces of the housing edge and the plastic body adhesives and or sealants contain undesirable ingredients that may be submitted and are not sufficiently resistant to aging. On the other hand, mechanical fasteners are expensive to produce and cause a variety of hygienic disadvantages, especially in cleaning.
Des weiteren ist es wünschenswert, insbesondere an der Oberfläche an der Schnittstelle zwischen den beiden Materialien einen möglichst ebenen, fugenfreien Übergang auszubilden, um ein Einlagern von Stoffen zu unterdrücken . Im allgemeinen sind hierzu nach dem Zusammenfügen aufwändige mechanische Nachbearbeitungsschritte notwendig, um die erforderliche Oberflächenbeschaffenheit zu gewährleisten. Furthermore, it is desirable, in particular on the surface at the interface between the two materials, to form as level as possible a joint-free transition in order to suppress the incorporation of substances. In general, this requires complex mechanical post-processing steps after assembly in order to ensure the required surface finish.

Gemäß dem Gegenstand der Erfindung nach Anspruch 7 wird ein Sensorgehäuse bereitgestellt, aufweisend eine Öffnung mit einem Rand und einer Seitenfläche die senkrecht zu der Oberfläche des Sensorgehäuses ein rücklaufendes Profil und einen schulterförmigen Absatz ausbildet, eine auf dem Absatz aufliegende streifenförmige Dichtung und ein Kunststoffkörper mit einer Seitenfläche, die teilweise stoßförmig an die Seitenfläche des Sensorgehäuses anliegt, wobei die Unterseite des Kunststoffkörpers teilweise auf der Dichtung -3- T/EP2010/003944 aufliegt und eine Verbindungsstelle, welche auf Oberseite des Sensorgehäuses und des Kunststoffkörpers einen im Wesentlichen fugenlosen und im Wesentlichen stufenfreien Übergang zwischen dem Sensorgehäuse und dem Kunststoffkörpers ausbildet. According to the subject matter of the invention according to claim 7, a sensor housing is provided, comprising an opening with an edge and a side surface perpendicular to the surface of the sensor housing forms a returning profile and a shoulder-shaped shoulder, resting on the shoulder strip-shaped seal and a plastic body with a Side surface which rests partially shock-shaped on the side surface of the sensor housing, wherein the underside of the plastic body partially on the seal T-EP2010 / 003944 rests and a connection point, which forms a substantially seamless and substantially stepless transition between the sensor housing and the plastic body on top of the sensor housing and the plastic body.
Ein Vorteil des erfindungsgemäßen Verfahrens ist es, dass zwei unterschiedliche Materialien ohne zusätzliche mechanische oder chemische Befestigungsmittel aneinandergefügt werden können. Ferner wird eine Ausbildung von Fugen und Stufen zumindest an deren Oberflächen unterdrückt. Hierdurch ist es möglich einen klebstofffreien Verbund auszubilden, der weitestgehend undurchlässig für atmosphärische Gase und oder Flüssigkeiten ist. Insbesondere bei einer Anwendung im Lebensmittelbereich unterdrückt die weitgehende Fugenfreiheit der Oberfläche und die Klebstofffreiheit eine unerwünschte Einlagerung von Stoffen oder eine Abgabe von Klebstoffmittel, die die hygienischen oder aseptischen Eigenschaften des Verbundes verschlechtern würden. Ferner wird aufgrund des Umformprozesses in Verbindung mit einer angepassten Profilführung von den beiden Seitenflächen ein stufenloser Übergang zwischen der Oberseite des Sensorgehäuses und der Oberseite des Kunststoffkörpers ohne die bisher notwendigen zusätzlichen Nachbearbeitungsschritte wie beispielsweise Polieren oder Fräsen erzielt. An advantage of the method according to the invention is that two different materials can be joined together without additional mechanical or chemical attachment means. Furthermore, a formation of joints and steps is suppressed at least on their surfaces. This makes it possible to form an adhesive-free composite which is largely impermeable to atmospheric gases and / or liquids. In particular, in an application in the food industry, the extensive freedom from joints of the surface and the freedom from adhesives suppresses an undesirable incorporation of substances or a release of adhesive agents, which would worsen the hygienic or aseptic properties of the composite. Furthermore, due to the forming process in conjunction with an adapted profile guide from the two side surfaces a stepless transition between the top of the sensor housing and the top of the plastic body without the previously necessary additional post-processing steps such as polishing or milling achieved.
In einer bevorzugten Weiterbildung des Verfahrens wird mittels der Umformung an der Seitenfläche des Sensorgehäuses ein rücklaufendes Profil ausgebildet, um den Kunststoffkörpers gegenüber dem Sensorgehäuse gegen eine senkrechte Verschiebung zu sichern. Des Weiteren ist es vorteilhaft, dass die Dichtung zwischen dem Sensorgehäuse und des Kunststoffkörpers aus einem elastischen Material wie beispielsweise Viton, Gummi oder Verbundkunststoffen besteht, um einen elastischen Formschluss zu erzeugen, der im Wesentlichen senkrecht zu der Metalloberfläche wirkt. Hierbei ist es vorteilhaft, wenn der äußere Rand des Kunststoffkörpers geeignet angefast wird, um die Ausbildung der hinterschnittenen Seitenfläche des Sensorgehäuses zu begünstigen. Gemäß einer anderen Weiterbildung ist es vorteilhaft, auch die Seitenfläche des Kunststoffkörpers mit einem stufenförmigen Absatz zu versehen. Hierbei wird das Profil des Absatz geeignet gewählt, so dass bei der Umformung nur die Unterseite des Absatzes des Kunststoffkörpers auf der Dichtung aufliegt und wenigstens ein Teil der Unterseite des Kunststoffkörpers zwischen den Rändern des Sensorgehäuses bei dem Umformprozess durchfedern kann. In a preferred embodiment of the method, a returning profile is formed by means of the forming on the side surface of the sensor housing in order to secure the plastic body against the sensor housing against a vertical displacement. Furthermore, it is advantageous that the seal between the sensor housing and the plastic body made of an elastic material such as viton, rubber or composite plastics to produce an elastic positive locking, which acts substantially perpendicular to the metal surface. It is advantageous if the outer edge of the plastic body is chamfered suitable to promote the formation of the undercut side surface of the sensor housing. According to another embodiment, it is advantageous to provide the side surface of the plastic body with a stepped shoulder. Here, the profile of the paragraph is chosen appropriately, so that during the forming only the bottom of the shoulder of the plastic body rests on the seal and at least a part of the underside of the plastic body between the edges of the sensor housing in the forming process can spring through.
Durch diese Ausbildung lässt sich, insbesondere unter Verwendung von optisch durchlässigen Kunststoffen, eine Möglichkeit zur Kontrolle von Fertigungsprozessen schaffen, ohne die Sensoren infolge direkten Kontakts mit chemisch oder mechanisch aggressiven Materialien zu beschädigen. Weiterhin ist es durch Wahl geeigneter Kunststoffe möglich, elektrische oder magnetische Felder durch den Kunststoffkörper, der im Allgemeinen scheibenförmig ausgebil¬ det ist, hindurch zusenden oder zu empfangen. Derartige Felder werden nämlich von Metallen im Allgemeinen abgeschirmt. This design makes it possible to control manufacturing processes, in particular using optically transparent plastics, without damaging the sensors as a result of direct contact with chemically or mechanically aggressive materials. Furthermore, it is possible by the choice of suitable plastics, electrical or magnetic fields through the plastic body, which is generally disk-shaped ausgebil ¬ det, send or receive. Namely, such fields are generally shielded from metals.
Untersuchungen der Anmelderin haben gezeigt, dass bei dem erfindungsgemäßen Gehäuse mit einliegendem Kunststoffkörper die Dichtung bevorzugt als elastischer umlaufender Streifen ausgebildet wird. Weiterhin können die elastischen Eigenschaften und die geometrische Ausführung der Dichtung je nach Anforderung und in Abhängigkeit von den bei der Umformung wirkenden Kräfte geeignet gewählt werden. Investigations by the applicant have shown that in the case of the housing according to the invention with an enclosed plastic body, the seal is preferably formed as an elastic circumferential strip. Furthermore, the elastic properties and the geometric design of the seal can be suitably selected depending on the requirements and depending on the forces acting during the deformation.

Des Weiteren wird mittels der Dichtung 40 die Seitenfläche 35 gegenüber der Seitenfläche 55 unter Ausbildung eines Spalts 78 abgedichtet. Je nach Größe und Elastizität der umlaufenden Dichtung 40 und in Abhängigkeit der geometrischen Abmessungen der Materialeigenschaften der verwendeten Metall- und Kunststoffflächen, sowie der Geometrie der stufenförmigen Absätze an den Seitenkanten, lässt sich sowohl der Anpressdruck des Kunststoffkörpers gegenüber dem Sensorgehäuse, als auch die Größe des Spaltes an der Seitenfläche einstellen.
