Description

Die vorliegende Erfindung betrifft einen Lufterhitzer mit einem Anschlussgehäuse für den Anschluss der elektrischen Energieversorgung und die zu erhitzende Luft und einem an dem Anschlussgehäuse über einen Trägerkörper befestigten Heizelement, wobei in dem Anschlussgehäuse mindestens zwei Netzspannung führenden Kontaktelemente angeordnet sind.The present invention relates to an air heater with a connection housing for the connection of the electrical power supply and the air to be heated and a heater attached to the terminal housing via a carrier body, wherein in the connection housing at least two line voltage leading contact elements are arranged.

Derartige Lufterhitzer sind allgemein bekannt und finden umfangreich Anwendung in der Industrie. Die Lufterhitzer erhitzen für die vielfältigsten Fertigungsprozesse entweder die von einer externen Luftquelle (Gebläse) herangeführte oder durch ein direkt an dem Lufterhitzer angeschlossenes Gebläse erzeugte Luft. Dabei wird die Luft durch ein Anschlussgehäuse für die elektrische Versorgung hindurch oder daran vorbei geführt und anschließend durch ein Heizelement erwärmt.Such air heaters are well known and are widely used in industry. The air heaters for the most varied manufacturing processes either heat the air supplied by an external air source (blower) or generated by a blower connected directly to the air heater. The air is passed through a connection housing for the electrical supply or past it and then heated by a heating element.

Diese Geräte müssen für die erzeugte Wärme und den Dauerbetrieb robust aufgebaut sein. Darüber hinaus soll auch die Montage möglichst einfach und schnell möglich sein, da eine Vielzahl derartiger Geräte in der Serienproduktion hergestellt werden. Bei den bisherigen Geräten erfordert gerade der Anschluss der elektrischen Anschlüsse bei der Montage erheblich Zeit.These devices must be robust for the generated heat and continuous operation. In addition, the assembly should be as simple and fast as possible, since a variety of such devices are manufactured in mass production. In the previous devices just requires the connection of the electrical connections during installation considerably time.

So ist bisher üblich die elektrische Kontaktierung insbesondere auch wegen der Isolation gegenüber der Gehäuse durch flexible Einzellitzen oder flexible Anschlussplattenverbinder herzustellen, wobei die elektrische Verbindung an den Kontaktstellen in der Regel durch Impulsschweißen oder durch Handlöten hergestellt wird. Eine derartige Verbindung ist zeitaufwendig herzustellen und verursacht hohe Montagekosten. Zudem besteht die Gefahr, dass die Verbindungsstelle durch mechanische Schläge oder Vibrationen unterbrochen und das Gerät dadurch funktionsunfähig wird. Ein weiterer Nachteil derartiger Litzenverbindungen ist die aufwendige Trennung der Verbindung im Reparaturfall.
Elektrische Verbindungen werden auch bei speziellen Anwendungen durch gummielastische, elektrisch leitfähige Verbindungselemente hergestellt, wobei die beschriebenen Nachteile nicht auftreten. Derartige elastische Verbindungselemente zur Kontaktierung elektrischer Bauelemente sind in zahlreichen Ausführungsformen bekannt und werden von vielen Herstellern unter der Bezeichnung Leitgummi auf dem Bauteilemarkt angeboten. Durch den Begriff Leitgummi wird zum Ausdruck gebracht, dass es sich dabei um ein Bauteil mit gummiähnlichen Eigenschaften handelt, welches elektrisch leitfähig ist. Es ist jedoch nicht zwingend aus Gummi hergestellt. Die elektrische Leitfähigkeit von Leitgummis wird durch Anreicherung des isolierenden Basismaterials mit leitfähigen Materialien erzeugt. So verwendet man seit langem derartige Kontaktvorrichtungen zur elektrischen Kontaktierung von LCD-Displays mit den Leiterbahnen von bestückten Schaltungs-Anschlussplatten (DE 88 08 947 U1).So far, it is customary to produce the electrical contact in particular also because of the insulation with respect to the housing by flexible stranded or flexible terminal plate connector, wherein the electrical connection is made at the contact points usually by pulse welding or by hand soldering. Such a connection is time consuming to produce and causes high assembly costs. In addition, there is a risk that the joint interrupted by mechanical shock or vibration and the device is thus inoperative. Another disadvantage of such stranded joints is the complex separation of the compound in case of repair.
Electrical connections are made in special applications by rubber-elastic, electrically conductive fasteners, the disadvantages described do not occur. Such elastic connecting elements for contacting electrical components are known in numerous embodiments and are offered by many manufacturers under the name Conductive rubber in the components market. The term conductive rubber expresses that it is a component with rubber-like properties, which is electrically conductive. However, it is not necessarily made of rubber. The electrical conductivity of conductive rubbers is created by enriching the insulating base material with conductive materials. So long used such contact devices for electrical contacting of LCD displays with the tracks of populated circuit connection plates (DE 88 08 947 U1).

Schwierigkeiten bei der Anwendung von Leitgummis ergeben sich immer dann, wenn die zu kontaktierenden Bauelemente eine von der parallelen Lage abweichende Lage einnehmen und/oder die Oberflächen nicht plan sind. Dann werden üblicherweise speziell ausgestaltete Leitgummis eingesetzt, die an die Geometrien und an die räumliche Lage der zu kontaktierenden Kontaktstellen angepasst sind. Da auch derartige Leitgummis ebenfalls elastische Eigenschaften haben müssen, ist jedoch eine sichere Positionierung und damit eine exakte Kontaktgabe problematisch, da sich die Leitgummis beim Aufbau des notwendigen Kontaktdruckes unkontrollierbar verformen können.Difficulties in the application of conductive rubbers always arise when the components to be contacted occupy a different position from the parallel position and / or the surfaces are not flat. Then specially designed conductive rubbers are usually used, which are adapted to the geometries and the spatial position of the contact points to be contacted. Since such conductive rubbers must also have elastic properties, however, a secure positioning and thus an exact contact problematic because the conductive rubbers can deform uncontrollably when building the necessary contact pressure.

Aufgabe der vorliegenden Erfindung ist es daher, einen derartigen Lufterhitzer vorzuschlagen, bei dem durch den Aufbau und die Anordnung der Anschlüsse für die Übertragung der elektrischen Heizleistung eine kostengünstige und schnelle Montage möglich ist. Zusätzlich soll auch der Anschluss für eine zugeordnete Steuereinrichtung leicht möglich sein.Object of the present invention is therefore to propose such an air heater, in which by the construction and arrangement of the terminals for the transmission of electrical heating power cost and fast assembly is possible. In addition, the connection should be easily possible for an associated control device.

Diese Aufgabe wird erfindungsgemäß durch einen Lufterhitzer mit den Merkmalen des Anspruchs 1 gelöst. Weitere vorteilhafte Ausgestaltungen sind den Unteransprüchen zu entnehmen.This object is achieved by an air heater with the features of claim 1. Further advantageous embodiments can be found in the dependent claims.

Der erfindungsgemäße Lufterhitzer weist ein Anschlussgehäuse für die elektrische Energieversorgung und die zu erhitzende Luft, sowie ein am Anschlussgehäuse über einen Trägerkörper befestigtes Heizelement auf. Im Anschlussgehäuse ist der Trägerkörper zur Übertragung der Heizleistung über eine Steckverbindung in Form von Steckkontaktstiften am Trägerkörper und entsprechenden Steckkontaktteilen im Anschlussgehäuse mit einer Anschlussplatte verbunden, auf der sich beispielsweise Anschlussklemmen für den Netzanschluss befinden. Hierzu weist das Anschlussgehäuse in der dem Heizelement zugewandten Gehäusewand mindestens zwei, mit den am Trägerkörper angeordneten Steckkontaktstiften fluchtende Einstecköffnungen auf. Die Steckkontaktstifte sind in einem Aufnahmewinkel im Anschlussgehäuse gegenüber dem Anschlussgehäuse, das üblicherweise metallisch ausgebildet ist, elektrisch isoliert gelagert.The air heater according to the invention has a connection housing for the electrical power supply and the air to be heated, and a heater attached to the connection housing via a carrier body. In the connection housing, the carrier body for transmitting the heating power via a plug connection in the form of plug contact pins on the carrier body and corresponding plug contact parts in the connection housing is connected to a connection plate on which, for example, terminals for the power connection. For this purpose, the connection housing in the housing wall facing the heating element has at least two insertion openings aligned with the plug contact pins arranged on the support body. The plug contact pins are mounted in a receiving angle in the connection housing opposite the terminal housing, which is usually formed metallic, electrically isolated.

Vorteilhafterweise ist der Aufnahmewinkel im Anschlussgehäuse eingelegt und weist mindestens zwei angeformte Dome auf, die durch die Einstecköffnungen durchführen und die Steckkontaktstifte isolieren. Grundsätzlich können noch weitere Dome für andere Anschlüsse vorhanden sein. Die Dome dienen neben der Isolierung auch als Abstandshalter bei der Montage für den Trägerkörper. Außerdem sind Anlageelemente und mindestens ein Befestigungselement für die Anschlussplatte vorgesehen. Durch diese Ausbildung des Aufnahmewinkels als Einlegeteil ist eine schnelle Montage möglich, wobei gleichzeitig eine stabile Durchführung für die elektrische Heizenergie mit entsprechender Isolierung gegenüber dem Anschlussgehäuse gewährleistet wird. Hierzu ist vorzugsweise der Aufnahmewinkel mit dem Anschlussgehäuse verrastbarAdvantageously, the receiving angle in the terminal housing is inserted and has at least two molded domes, which perform through the insertion and insulating the plug contact pins. In principle, other dome for other connections may be present. The dome serve in addition to the insulation as a spacer during assembly for the carrier body. In addition, contact elements and at least one fastening element for the connection plate are provided. Due to this design of the receiving angle as an insert is a quick installation possible, while ensuring a stable implementation of the electrical heating energy with appropriate insulation against the terminal housing. For this purpose, preferably the receiving angle can be latched to the connection housing

In einer weiteren vorteilhaften Ausgestaltung sind zum Abgriff von Referenzspannungen für die Steuereinrichtung die Steckkontaktstifte mit den Kontaktbahnen der Anschlussplatte über gummielastische, leitfähige Verbindungselemente verbindbar, um Signale zu einer auf der Anschlussplatte angeordneten Steuereinrichtung (Mikroprozessor) zu verbinden. Vorzugsweise wird zur Kontaktierung und Verbindung der Kontaktflächen der Anschlussplatte und der Steckkontaktstifte Leitgummi eingesetzt, das zu einem gummielastischen elektrisch leitenden Formteil verarbeitet ist. Der an sich isolierende Grundstoff ist mit elektrisch leitfähigen Partikeln aus Metall oder Kohlenstoff angereichert, wodurch das Leitgummi stromleitfähig ist. Durch Variation des leitfähigen Materials bzw. dessen Anteils lässt sich der Leitwert des Verbindungselements verändern. Damit kann über die auf der Anschlussplatte angeordnete Steuereinrichtung die Spannung an den Steckkontaktstiften erfasst und ausgewertet werden. Zusätzlich können die Verbindungselemente auch zur Strombegrenzung verwendet werden.In a further advantageous refinement, the plug contact pins can be connected to the contact tracks of the connection plate via rubber-elastic, conductive connection elements in order to tapped reference voltages for the control device in order to connect signals to a control device (microprocessor) arranged on the connection plate. Preferably, conductive rubber is used for contacting and connecting the contact surfaces of the terminal plate and the plug contact pins, which is processed into a rubber-elastic electrically conductive molding. The inherently insulating base material is enriched with electrically conductive particles of metal or carbon, whereby the conductive rubber is conductive. By varying the conductive material or its proportion, the conductance of the connecting element can be changed. In this way, the voltage at the plug contact pins can be detected and evaluated via the control device arranged on the connection plate. In addition, the connecting elements can also be used for current limiting.

In einer vorteilhaften Ausgestaltung wird das elastische Verbindungselement in einer als U-förmige Halbschale ausgebildeten Lagerschale am Boden des Aufnahmewinkels gehaltert. Die Aufnahme des elastischen Verbindungselements in der Lagerschale bewirkt eine lagegenaue Positionierung sowie eine Abstützung, damit sich das Verbindungselement beim Aufbau des Kontaktdruckes nicht unkontrollierbar verformt.In an advantageous embodiment, the elastic connecting element is held in a trained as a U-shaped half-shell bearing cup at the bottom of the receiving angle. The inclusion of the elastic connecting element in the bearing shell causes a positionally accurate positioning and a support, so that the connecting element does not deform uncontrollably when building the contact pressure.

Das Anschlussgehäuse nimmt über den Aufnahmewinkel die aus Steckkontaktteilen und den korrespondierenden Steckkontaktstiften bestehende Steckverbindung sowie die Steuereinrichtung in einer abgeschlossenen Kammer auf. In einer vorteilhaften Ausgestaltung sind die Steckkontaktstifte als zylindrische Kontaktbuchsen ausgeführt, die auf einem ringförmigen Trägerkörper angeordnet sind. Die korrespondierenden Steckkontaktteile sind stiftförmig ausgebildet und an isolierten elektrischen Einzellitzen leitend angeschlagen, die über Klemmenblöcke mit der Anschlussplatte der Steuereinrichtung verbindbar sind. Es ist jedoch auch möglich, am Trägerkörper Steckerstifte und an den Litzen Steckbuchsen vorzusehen. Der Trägerkörper weist mehrere Steckkontaktstifte auf, von denen mindestens zwei Netzspannung führen. Die nicht Netzspannung führenden Steckkontaktstifte werden zum Anschluss von Sensoren der Steuereinrichtung und/oder zur Erdung metallischer Geräteteile verwendet. Die für Regelung durch die Steuereinrichtung benötigten Spannungen oder Signale werden an den Steckkontaktstiften abgenommen, die durch die gummielastischen Verbindungselemente kontaktierbar sind.The terminal housing takes on the receiving angle on the plug-in contact parts and the corresponding plug contact pins existing connector and the control device in a sealed chamber. In an advantageous embodiment, the plug contact pins are designed as cylindrical contact sockets, which are arranged on an annular carrier body. The corresponding plug contact parts are pin-shaped and isolated electric single stranded conductive, which are connectable via terminal blocks with the connection plate of the control device. However, it is also possible to provide plug pins on the carrier body and sockets on the wires. The carrier body has a plurality of plug contact pins, of which lead at least two mains voltage. The non-mains voltage leading plug pins are used to connect sensors of the controller and / or for grounding metallic equipment parts. The voltages or signals required for regulation by the control device are removed at the plug contact pins, which can be contacted by the rubber-elastic connecting elements.

Vorzugsweise ist das Verbindungselement einstückig und homogen ausgeführt und weist an seinem Körper eine Aussparung zur Aufnahme des Steckkontaktstifts auf. Die Aussparung ist an die Geometrie und an die Maße des Steckkontaktstifts angepasst und vorteilhafterweise als Bohrung ausgeführt, wobei der Innenumfang der Bohrung geringfügig kleiner ist als der Außenumfang des Steckkontaktstifts. Durchdringt der Steckkontaktstift die Bohrung des Verbindungselements, so wird die Bohrung aufgeweitet, wodurch das Verbindungselement formschlüssig und mit Druck am Mantel des Steckkontaktstifts anliegt.Preferably, the connecting element is made in one piece and homogeneous and has on its body a recess for receiving the plug contact pin. The recess is adapted to the geometry and the dimensions of the plug contact pin and advantageously designed as a bore, wherein the inner circumference of the bore is slightly smaller than the outer circumference of the plug contact pin. If the plug contact pin penetrates the bore of the connecting element, the bore is widened, as a result of which the connecting element rests positively and with pressure on the jacket of the plug contact pin.

In einer weiteren vorteilhaften Ausgestaltung weist das Verbindungselement an der der Anschlussplatte zugeordneten Seite ein Anpresselement zur Kontaktierung der Kontaktbahnen der Anschlussplatte auf. Das Anpresselement ragt aus dem Körper des Verbindungselements hervor, ist zylindrisch ausgeführt und am Körper des Verbindungselements angeformt. Das Anpresselement kann auch eine andere Form aufweisen oder aus mehreren einzelnen Anpresselementen zusammengesetzt sein. Vorteilhafterweise erfolgt die Kontaktierung der Kontaktbahnen durch Anpressen der Anschlussplatte an die im Aufnahmewinkel gelagerten Verbindungselemente, welche von den Steckkontaktstiften durchdrungen werden. Durch das Fixieren der Anschlussplatte am Aufnahmewinkel wird das Verbindungselement zusammengepresst und der Kontaktdruck aufrechterhalten.In a further advantageous embodiment, the connection element on the side assigned to the connection plate has a contact pressure element for contacting the contact paths of the connection plate. The pressing element protrudes from the body of the connecting element, is cylindrical and integrally formed on the body of the connecting element. The pressing element may also have a different shape or be composed of several individual pressing elements. Advantageously, the contacting of the contact tracks by pressing the connection plate to the mounted in the receiving angle connecting elements, which are penetrated by the plug contact pins. By fixing the terminal plate at the receiving angle, the connecting element is compressed and the contact pressure is maintained.
