Description
Die vorliegende Erfindung betrifft eine elektrische Anordnung, welche geeignet ist, in einem Türantrieb und/oder einem Türschließer elektrische Signale weiterzuleiten.The present invention relates to an electrical arrangement which is suitable for forwarding electrical signals in a door drive and / or a door closer.
Im Stand der Technik werden zur Verteilung elektrischer Signale und/oder Spannungen bzw. Leistungen in Türantrieben und/oder Türschließern zumeist Kabel verwendet, mit welchen einzelne Kontakte an entlegenen Enden des Gehäuses des Türantriebs elektrisch verbunden werden. Diese elektrischen Kabel müssen an den übrigen Bestandteilen des Gehäuses (z. B. Getriebe, Netzteil, Steuerungsleiterkarten, Motor sowie Trägerkörper für die vorgenannten Elemente) vorbei verlegt werden, wodurch einerseits der Fertigungsaufwand, andererseits das Risiko einer Beschädigung erhöht wird. Zudem ist entsprechender Bauraum im Gehäuse vorzuhalten, wodurch das Gehäuse ein höheres Volumen aufweisen muss und daher höhere Materialaufwendungen notwendig sind. Zudem ist es aus ästhetischen Gesichtspunkten ein Bestreben, Türantriebe und Türsteuerungen kleinvolumig zu gestalten. Vorkonfektionierte Kabelbäume kommen zwar zum Einsatz, können die wesentlichen Nachteile des Standes der Technik jedoch nicht umfassend und zufrieden stellend mindern.In the prior art, cables are mostly used for distributing electrical signals and / or voltages or powers in door drives and / or door closers, with which individual contacts are electrically connected to remote ends of the housing of the door drive. These electrical cables must be routed past the other components of the housing (eg gearbox, power supply unit, control conductor cards, motor and carrier body for the aforementioned elements), which on the one hand increases the manufacturing effort and on the other hand increases the risk of damage. In addition, appropriate space must be provided in the housing, whereby the housing must have a higher volume and therefore higher material costs are necessary. Moreover, from an aesthetic point of view, it is a desire to make door drives and door controls small-volume. Although prefabricated cable harnesses are used, they can not comprehensively and satisfactorily reduce the major disadvantages of the prior art.
Es ist daher eine Aufgabe, die elektrischen Verbindungen innerhalb eines Türantriebs und/oder eines Türschließers zu vereinfachen bzw. zu verbessern.It is therefore an object to simplify or improve the electrical connections within a door drive and / or a door closer.
Die vorgenannte Aufgabe wird gelöst durch eine elektrische Anordnung mit den Merkmalen nach Anspruch 5 sowie Verfahren zur Herstellung einer solchen elektrischen Anordnung mit den Merkmalen gemäß Anspruch 1 bzw. 3.The above object is achieved by an electrical arrangement with the features of claim 5 and a method for producing such an electrical arrangement having the features of
Erfindungsgemäß weist die elektrische Anordnung ein Spritzgussteil aus Kunststoff auf, welches als Trägerkörper für Elemente im Inneren des Türantriebs dienen kann, andererseits jedoch auch Anteile des Gehäuses in sich vereinen kann. Beispielsweise kann ein unterer Teil des Gehäuses einen solchen Trägerkörper beinhalten, wobei ein oberer Teil des Gehäuses als Deckel auf den unteren Teil des Gehäuses bzw. des Trägerkörpers aufgesetzt wird. Darüber hinaus weist die elektrische Anordnung metallische Stanzteile auf, welche mit dem Spritzgussteil formschlüssig verbunden sind. Die metallischen Stanzteile können aus elektrisch leitendem Werkstoff wie beispielsweise Metallblech bestehen und bereits im Zuge eines Spritzgussverfahrens zur Herstellung des Spritzgussteils in den Kunststoff integriert worden sein. Einerseits schützt dies die Stanzteile vor Korrosion und mechanischer Beschädigung, andererseits isoliert ein Einbetten des Stanzteils im Spritzgussteil das Stanzteil elektrisch von seiner Umgebung. Darüber hinaus kann ein Stanzteil auch die Festigkeit der gesamten Anordnung erhöhen. Zum Zwecke der elektrischen Kontaktierung können vordefinierte Bereiche des Stanzteils auf dem Spritzgussteil hervorstehen. Bevorzugt wird hierfür während des Spritzgussvorgangs dadurch Sorge getragen, dass die zur elektrischen Kontaktierung dienenden Bereiche des Stanzteils außerhalb des mit Kunststoff zu füllenden Volumens angeordnet sind.According to the invention, the electrical arrangement comprises an injection-molded part made of plastic, which can serve as a carrier body for elements in the interior of the door drive, but on the other hand can also combine parts of the housing in itself. For example, a lower part of the housing may include such a carrier body, wherein an upper part of the housing is placed as a lid on the lower part of the housing or the carrier body. In addition, the electrical arrangement on metallic stampings, which are positively connected to the injection molded part. The metallic stampings may be made of electrically conductive material such as sheet metal and have already been integrated in the course of an injection molding process for the production of the injection molded part in the plastic. On the one hand, this protects the stamped parts against corrosion and mechanical damage, on the other hand, an embedding of the stamped part in the injection-molded part electrically isolates the stamped part from its surroundings. In addition, a stamped part can also increase the strength of the entire assembly. For the purpose of electrical contacting, predefined regions of the stamped part can project on the injection-molded part. During the injection molding process, this is preferably done by ensuring that the areas of the stamped part serving for electrical contacting are arranged outside the volume to be filled with plastic.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung wird ein Verfahren zur Herstellung einer elektrischen Anordnung für einen Türantrieb vorgeschlagen. Gemäß diesem wird ein Spritzgussteil aus Kunststoff erzeugt, welches als Gehäuseteil und/oder Trägerkörper in einem elektrischen Türantrieb dienen kann. An seiner Oberfläche weist das Spritzgussteil Vertiefungen auf, welche eingerichtet sind, ein metallisches Stanzteil aufzunehmen. Gegenüber der Oberfläche des Spritzgussteils sind die Vertiefungen lediglich wenige Millimeter tief, so dass ein Metallblech als metallisches Stanzteil in die Vertiefungen eingelassen werden kann. Die Befestigung des Metallteils kann beispielsweise durch Kleben, Klemmen
oder Umformen des Spritzgussteils erfolgen. Alternativ oder zusätzlich kann auch ein zweiter Spritzgussvorgang nun mit dem integrierten metallischen Stanzteil vorgenommen werden.According to a further aspect of the present invention, a method for producing an electrical arrangement for a door drive is proposed. According to this an injection molded part is produced from plastic, which can serve as a housing part and / or carrier body in an electric door drive. On its surface, the injection-molded part has recesses which are adapted to receive a metallic stamped part. Opposite the surface of the injection-molded part, the recesses are only a few millimeters deep, so that a metal sheet can be inserted as a metallic stamped part in the wells. The attachment of the metal part, for example, by gluing, clamping
or forming the injection molded part done. Alternatively or additionally, a second injection molding process can now be carried out with the integrated metallic stamped part.
Vorzugsweise sind in den Vertiefungen Dome vorgesehen, welche mit Durchbrüchen im metallischen Stanzteil derart korrespondieren, dass nach einem Einlegen des metallischen Stanzteils in die Vertiefungen des Spritzgussteils die Dome das metallische Stanzteil durchdringen und das Stanzteil durch einen Vorgang des Heißverprägens formschlüssig mit dem Spritzgussteil verbunden werden kann. Gemäß einer alternativen Ausführungsform flankieren Dome die Vertiefungen und umgreifen das Stanzteil im Zuge eines Heißverprägens.Dome are preferably provided in the recesses, which correspond with openings in the metallic stamped part such that after inserting the metallic stamped part in the recesses of the injection molded part, the dome penetrate the metallic stamped part and the stamped part can be positively connected by a process of Heißverprägens with the injection molded part , According to an alternative embodiment, domes flank the recesses and embrace the stamped part in the course of a hot stamping.
Gemäß einem weiteren Aspekt der vorliegenden Erfindung wird ein alternatives Verfahren zur Herstellung einer elektrischen Anordnung vorgeschlagen, bei welchem ein metallisches Stanzteil in eine Spritzgussform eingelegt wird. Anschließend wird die Spritzgussform geschlossen und Kunststoffmasse eingespritzt. Hierbei umschließt der eingespritzte Kunststoff das Stanzteil bis auf diejenigen Bereiche des Stanzteils, welche zum Zwecke der elektrischen Kontaktierung außerhalb des Spritzvolumens bzw. der Spritzform angeordnet sind.According to a further aspect of the present invention, an alternative method for producing an electrical arrangement is proposed, in which a metallic stamped part is inserted into an injection mold. Subsequently, the injection mold is closed and injected plastic compound. Here, the injected plastic surrounds the stamped part except for those areas of the stamped part, which are arranged for the purpose of electrical contacting outside the injection volume or the injection mold.
Vorzugsweise können die vorstehend genannten Verfahren weitergebildet werden, indem vordefinierte Verbindungsstege zwischen Bereichen des Stanzteils z. B. noch innerhalb der Spritzgussform durchtrennt werden. Beispielsweise kann nach einem Schließen der Spritzgussform, wobei das Stanzteil durch Schließen der Spritzgussform fixiert wird, ein Stanzvorgang die Verbindungsstege durchtrennen und die vordefinierten Bereiche des Stanzteils somit elektrisch voneinander isolieren. Anschließend wird Kunststoff eingespritzt, wodurch die vordefinierten Bereiche des Stanzteils dauerhaft elektrisch voneinander isoliert und ihre mechanische Lage zueinander fixiert wird.Preferably, the aforementioned methods can be developed by predefined connecting webs between areas of the stamped part z. B. are still severed within the injection mold. For example, after closing the injection mold, wherein the stamped part is fixed by closing the injection mold, a punching process cut through the connecting webs and thus electrically isolate the predefined regions of the stamped part from one another. Subsequently, plastic is injected, whereby the predefined areas of the stamped part permanently electrically isolated from each other and their mechanical position is fixed to each other.
Im Folgenden werden vorteilhafte Ausgestaltungen einzelner Merkmale der erfindungsgemäßen elektrischen Anordnung diskutiert, welche jedoch auch für entsprechende Ausgestaltungen der erfindungsgemäßen Verfahren gelten, ohne dass dies im Einzelnen erwähnt wird.In the following, advantageous embodiments of individual features of the electrical arrangement according to the invention are discussed, which, however, also apply to corresponding embodiments of the method according to the invention, without this being mentioned in detail.
Vorteilhaft kann das Kunststoffspritzteil möglichst viele Funktionen vereinen, wodurch sich der Aufwand für Fertigung und Montage verringert. Daher wird vorgeschlagen, das Kunststoffspritzteil als zumindest ein Teil des Gehäuses für einen Türantrieb bzw. einen Türschließer auszugestalten. Elemente bzw. Aggregate des Türantriebs, wie beispielsweise Motor, Getriebe, Netzteile, Befestigungselemente und Steuerungsleiterkarten, können ebenso in ihm vorgesehen werden, wie beispielsweise Schnapp-/ Rastelemente, mit welchen ein Deckel bzw. ein zweites Gehäuseteil auf dem Spritzgussteil gehalten werden kann. Die Fertigung als Kunststoffspritzteil ermöglicht dabei eine kostengünstige sowie mechanisch hochbelastbare Anfertigung bei vergleichsweise geringem Gewicht der Gesamtanordnung. Weiter vorzugsweise kann das Kunststoffspritzteil eine schallentkoppelnde Montageplatte für einen Türantrieb sein. Insbesondere bei geeigneter Wahl des Kunststoffes können sich im Spritzgussteil ausbreitende Schwingungen nur in reduziertem Maße auf beispielsweise ein Türblatt oder eine Wand, an welchem bzw. welcher der Türantrieb befestigt ist, fortpflanzen. Als Montageplatte sei im Rahmen der vorliegenden Erfindung also derjenige Teil zu verstehen, mit welchem die elektrische Anordnung in ihrer Umgebung festgelegt wird.Advantageously, the plastic injection molded part combine as many functions, thereby reducing the cost of manufacture and assembly is reduced. It is therefore proposed to design the plastic injection-molded part as at least part of the housing for a door drive or a door closer. Elements or units of the door drive, such as motor, gearbox, power supplies, fasteners and control cards, can also be provided in it, such as snap / locking elements, with which a lid or a second housing part can be held on the injection molded part. The production as a plastic injection molded part allows a cost-effective and mechanically heavy-duty production at a comparatively low weight of the overall arrangement. Further preferably, the plastic injection-molded part can be a sound-decoupling mounting plate for a door drive. In particular, with a suitable choice of the plastic can propagating in the injection molded part Vibrations only to a reduced extent on, for example, a door leaf or a wall to which or which the door drive is attached propagate. As a mounting plate in the context of the present invention, therefore, that part to understand, with which the electrical arrangement is set in their environment.
Weiter vorteilhaft kann das Stanzteil Durchbrüche zur Positionierung innerhalb der Spritzgussform aufweisen, welche mit Positionierhilfen innerhalb einer Spritzgussform korrespondieren können. Auf diese Weise kann das Stanzteil innerhalb einer Spritzgussform in einer vordefinierten Lage angeordnet und während des Spritzgießens in dieser fixiert werden.Further advantageously, the stamped part can have openings for positioning within the injection mold, which can correspond with positioning aids within an injection mold. In this way, the stamped part can be arranged within an injection mold in a predefined position and fixed therein during injection molding.
Weiter vorteilhaft kann das Stanzteil an denjenigen Bereichen, welche nicht vom Spritzgussteil umgeben sind, Verbindungselemente zum Herstellen elektrischer Kontakte aufweisen oder zur Anbringung entsprechender Verbindungselemente eingerichtet sein. Beispielsweise können die Kontaktbereiche als Schneid-/Klemmkontakte und/oder Steckkontakte und/oder Lötfahnen ausgebildet sein. Auf diese Weise reduziert sich der Aufwand für zusätzliche Teile, mit welchen üblicherweise elektrische Kontakte hergestellt werden, und die Bauform kann Platz sparend gestaltet werden.Further advantageously, the stamped part at those areas which are not surrounded by the injection molded part, have connecting elements for producing electrical contacts or be set up for attaching corresponding connecting elements. For example, the contact areas may be formed as cutting / clamping contacts and / or plug contacts and / or Lötfahnen. In this way reduces the cost of additional parts, with which usually electrical contacts are made, and the design can be made space-saving.
Bevorzugt kann das Kunststoffspritzteil als Gehäuse für einen Antrieb ausgestaltet sein, welcher somit kein vollständiges eigenes bzw. gar kein Gehäuse aufweisen muss. Beispielsweise könnten Stator, Rotor und Welle eines Elektroantriebes direkt in entsprechende Ausnehmungen des Kunststoffspritzteils eingesetzt werden und gegebenenfalls durch einen Deckel fixiert werden. Somit ist das Kunststoffspritzteil als Aggregatträger verwendbar. Ebenso kann das Kunststoffspritzteil gemäß der vorliegenden Erfindung mechanische (Gehäuse-)Bestandteile eines Netzteils erübrigen. Weiter vorteilhaft kann die elektrische Anordnung einen integrierten Steckanschluss für Stecker und/oder Karten mit elektrischen Leiterbahnen zur Steuerung der Komponenten eines Türantriebes aufweisen. Gegebenenfalls können zur Befestigung dieser oder weiterer Elemente Schnapp-/Rastelemente in das Kunststoffspritzteil oder in einen für dieses vorgesehenen Deckel integriert sein.Preferably, the plastic injection-molded part can be designed as a housing for a drive, which thus does not have to have its own complete or even no housing. For example, stator, rotor and shaft of an electric drive could be used directly in corresponding recesses of the plastic injection molded part and optionally fixed by a cover. Thus, the plastic injection molded part is usable as an aggregate carrier. Likewise, the plastic injection molded part according to the present invention can eliminate mechanical (housing) components of a power supply. Further advantageously, the electrical arrangement can have an integrated plug connection for plugs and / or cards with electrical conductor tracks for controlling the components of a door drive. Optionally, snap-in / latching elements may be integrated in the plastic injection-molded part or in a cover provided for this purpose for fastening these or other elements.
Insbesondere bevorzugt kann das Kunststoffspritzteil eingerichtet sein, einen Deckel aufzunehmen, welcher Stempelelemente aufweist. Diese Stempelelemente können mit Kavitäten im Kunststoffspritzteil beispielsweise dahingehend zusammenwirken, dass in das Kunststoffteil eingelegte elektrische Elemente, wie beispielsweise Anschlussleitungen, in die im Kunststoffspritzteil vorgesehenen Schneid-/Klemmkontakte des Stanzteils zur Herstellung einer Schneid-/ Klemmverbindung gedrückt werden. Mit anderen Worten führt ein Schließen des Kunststoffspritzteils mittels eines wie vorstehend ausgeführt eingerichteten Deckels auch zu einem Schließen einer Schneid-Klemmverbindung, durch welche in das Kunststoffspritzteil eingelegte elektrische Elemente mit dem Stanzteil verbunden werden.Particularly preferably, the plastic injection-molded part may be adapted to receive a lid, which has stamping elements. These stamp elements can co-operate with cavities in the plastic injection-molded part, for example, in that electrical elements inserted in the plastic part, such as connection lines, are pressed into the cutting / clamping contacts of the stamped part provided in the plastic injection part for producing a cutting / clamping connection. In other words, closing the plastic injection-molded part by means of a lid as set forth above also leads to a closing of an insulation displacement connection, through which electrical elements inserted into the plastic injection-molded part are connected to the stamped part.
