Description

Technisches GebietTechnical field

Die Erfindung betrifft eine elektrische Baueinheit mit einem Steuergerät, insbesondere einem Vorschaltgerät für eine Leuchtstofflampe, das an einer Trageinrichtung, insbesondere einer Wanne einer elektrischen Leuchte, montiert ist gemäss dem Oberbegriff des Patentanspruchs 1.The invention relates to an electrical unit with a control unit, in particular a ballast for a fluorescent lamp, which is attached to a support device, in particular a tub of an electric light, is mounted according to the preamble of claim 1.

Stand der TechnikState of the art

Leuchtstofflampen benötigen Vorschaltgeräte für die Zündung und zur Strombegrenzung im Betrieb. Dabei werden konventionelle Vorschaltgeräte (KVG) und elektronische Vorschaltgeräte (EVG) eingesetzt. Die letztgenannten elektronischen Vorschaltgeräte haben sich in Bezug auf die Qualität und die Zuverlässigkeit bewährt. Des weiteren haben elektronische Vorschaltgeräte wesentlich geringere Verluste als konventionelle Vorschaltgeräte, wobei durch den Betrieb mit Hochfrequenz die Leuchtstofflampen eine höheren Lichtausbeute mit einem flackerfreien Licht aufweisen.Fluorescent lamps require ballasts for the ignition and to limit the current operational. It uses conventional ballasts (KVG) and electronic ones Ballasts used. The latter electronic ballasts have proven themselves in terms of quality and reliability. Furthermore, electronic ballasts have much lower losses than conventional ballasts, the operation with high frequency Fluorescent lamps have a higher light output with a flicker-free light.

Üblicherweise ist ein derartiges Vorschaltgerät in einem Gehäuse aufgenommen, das zusammen mit der Leuchtstofflampe und den Fassungen für die Lampe in eine Wanne einer Leuchte eingesetzt wird. Zur Erdung der Leuchtenwanne wird diese mit dem Gehäuse des Vorschaltgerätes elektrisch leitend verbunden. Diese Erdung kann beispielsweise durch eine Schraubverbindung zwischen Gehäuse und Leuchtenwanne erfolgen, wobei durch entsprechende Ausgestaltung der Schraubverbindung sichergestellt ist, dass ein zuverlässiger Kontakt zwischen Leuchtenwanne und Gehäuse herstellbar ist. Alternativ kann die Erdung auch über ein Schutzleiter-Kabel erfolgen, das das Gehäuse elektrisch mit der Leuchtenwanne verbindet. Such a ballast is usually accommodated in a housing in a tub together with the fluorescent lamp and the holders for the lamp a lamp is used. To ground the lamp tray, this is with the Ballast housing electrically connected. This grounding can, for example thanks to a screw connection between the housing and luminaire tray take place, ensured by appropriate design of the screw connection is that a reliable contact between luminaire tray and housing can be produced. Alternatively, grounding can also be carried out using a protective conductor cable, that electrically connects the housing to the lamp tray.

Nachteilig bei diesen Lösungen ist, dass ein erheblicher Montageaufwand erforderlich ist, um die Leuchtenwanne mit dem Vorschaltgerät zu verbinden und den Schutzleiterkontakt herzustellen.The disadvantage of these solutions is that they require considerable assembly effort is to connect the lamp tray with the ballast and the Establish protective conductor contact.

Eine derartige Problematik besteht im Prinzip bei allen elektrischen Baueinheiten mit Steuer- und Stromversorgungsgeräten, die über einen Schutzleiterkontakt mit einem das Gerät aufnehmenden Leuchtenwanne, einer Tragkonsole oder ähnlichem zu verbinden sind.Such a problem exists in principle with all electrical components Control and power supply devices that have a protective conductor contact with a to connect the device-receiving lamp tray, a support bracket or the like are.

Darstellung der ErfindungPresentation of the invention

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, eine elektrische Baueinheit zu schaffen, bei der ein Schutzleiterkontakt auf einfache Weise herstellbar ist.In contrast, the invention has for its object an electrical assembly to create, in which a protective conductor contact can be produced in a simple manner.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This object is achieved by the characterizing features of patent claim 1 solved.

Erfindungsgemäß weist die elektrische Baueinheit ein Steuergerät auf, das mit seinem Gehäuse an einer Trageinrichtung einer anzusteuernden elektrischen Einrichtung, beispielsweise einer Leuchte befestigt ist. Die mechanische und elektrische Verbindung erfolgt erfindungsgemäß über zumindest eine Biegelasche, die entweder am Gehäuse oder - in kinematischer Umkehr - an der Trageinrichtung ausgebildet ist und die zur Herstellung der mechanischen und elektrischen Verbindung derart verformbar ist, dass sie form- oder kraftschlüssig in eine Ausnehmung des jeweils anderen Bauteils, d.h. der Trageinrichtung oder des Gehäuses eingreift. D.h., zur Montage des elektrischen Steuergerätes wird dieses auf die Trageinrichtung aufgesetzt und anschließend durch Umbiegen der Biegelasche(n) die mechanische Verbindung und der Schutzleiterkontakt hergestellt. Im Gegensatz zum eingangs beschriebenen Stand der Technik bedarf es keiner aufwendigen Schraubverbindung oder der Ausbildung eines zusätzlichen Schutzleiter-Kabels, über das das Gehäuse und die Trageinrichtung elektrisch miteinander verbunden sind.According to the invention, the electrical unit has a control unit which, with its Housing on a support device of an electrical device to be controlled, for example, a lamp is attached. The mechanical and electrical Connection takes place according to the invention via at least one bending tab, which either is formed on the housing or - in kinematic reversal - on the carrying device and so deformable for establishing the mechanical and electrical connection is that they are positively or non-positively in one recess of the other Component, i.e. the support device or the housing engages. That is, for assembly of the electrical control unit, this is placed on the carrying device and then by bending the bending tab (s) the mechanical connection and the protective conductor contact is established. In contrast to the stand described at the beginning the technology does not require any complex screw connection or training an additional protective conductor cable, via which the housing and the carrying device are electrically connected to each other.

Bei dem elektrischen Steuergerät handelt es sich vorzugsweise um ein Vorschaltgerät für eine Leuchtstofflampe. Prinzipiell lässt sich die Erfindung jedoch auch bei anderen elektrischen Baueinheiten einsetzen, bei denen ein Steuer- oder Stromversorgungsgerät mechanisch und elektrisch mit einer Trageinrichtung zu verbinden ist. The electrical control device is preferably a ballast for a fluorescent lamp. In principle, however, the invention can also be applied to others use electrical units in which a control or power supply device is to be connected mechanically and electrically to a carrying device.

Bei einer besonders bevorzugten Ausführungsform ist die Biegelasche durch eine Ausstanzung ausgebildet, die im umgebogenen Zustand einen Umfangskantenabschnitt der Ausnehmung umgreift, um die mechanische und elektrische Verbindung herzustellen.In a particularly preferred embodiment, the bending tab is a Punched out formed a peripheral edge portion in the bent state of the recess encompasses the mechanical and electrical connection manufacture.

Die Festigkeit der mechanischen Verbindung lässt sich erhöhen, wenn die Biegelasche einen die Ausnehmung überdeckenden Verriegelungsabschnitt hat, dessen Grundfläche etwas kleiner als diejenige der Ausnehmung ist, so dass beim Umbiegen der Biegelasche der Verriegelungsabschnitt eine Umfangskante der Ausnehmung umgreift und eine Hinterschneidung ausbildet.The strength of the mechanical connection can be increased if the bending tab has a locking portion covering the recess, the Base area is slightly smaller than that of the recess, so that when bending the bending tab of the locking section a peripheral edge of the recess grips and forms an undercut.

Erfindungsgemäß wird es bevorzugt, wenn die Ausnehmung an der Trageinrichtung, beispielsweise der Wanne der Leuchte und die Biegelasche(n) am Gehäuse des Steuergerätes, beispielsweise des Vorschaltgerätes für die Leuchtstofflampe ausgebildet ist.According to the invention, it is preferred if the recess on the support device, for example the tub of the lamp and the bending tab (s) on the housing of the control unit, for example, the ballast for the fluorescent lamp is.

Die Montage der erfindungsgemäßen Baueinheit ist besonders einfach, wenn jede Biegelasche durch einen in die Ausnehmung einsetzbaren Einpressdorn in ihre Eingriffsposition bringbar ist.The assembly of the assembly according to the invention is particularly simple if each Bending tab into its engagement position by a press-in mandrel that can be inserted into the recess is feasible.

Der vorrichtungs- und fertigungstechnische Aufwand lässt sich weiter verringern, wenn jeder Biegelasche ein Einpressdorn zugeordnet ist, der einstückig an einem Bauelement des Steuergeräts ausgebildet ist. Durch diese Weiterbildung der Erfindung bedarf es keines zusätzlichen Montagewerkzeuges, um die Biegelaschen aus ihrer Grundposition in die Verriegelungsposition zu bringen.The outlay on equipment and production technology can be further reduced, if each bending tab is assigned a press-in mandrel, which is integral with one Component of the control unit is formed. Through this development of the invention there is no need for an additional assembly tool to remove the bending tabs to bring their basic position into the locking position.

Dieses Bauelement kann beispielsweise eine Untersteckwanne für eine Anschlussklemme oder ein Montagerahmen des Vorschaltgerätes sein. Dabei wird es besonders bevorzugt, wenn jeder Einpressdorn über ein Filmscharnier an der im Kunststoffspritzgießverfahren hergestellten Untersteckwanne oder an dem Montagerahmen angebunden ist.This component can, for example, a bottom trough for a connection terminal or a mounting frame of the ballast. It will be special preferred if each press mandrel has a film hinge on the plastic injection molding process manufactured under-tray or on the mounting frame is connected.

Zusätzlich kann der Einpressdorn eine Nut am Umfang aufweisen durch den er an der Leuchtenwanne verriegelbar ist. Vorteilhaft ist der Einpressdorn dabei so geformt, dass er eine Positionierung und Ausrichtung zu der Ausnehmung der Leuchtenwanne vornimmt. Damit ist eine exakte Ausrichtung der Untersteckwanne und damit der an der Untersteckwanne befestigten Anschlussklemme bzw. des an der Untersteckwanne befestigten Montagerahmens gegenüber der Ausnehmung in der Leuchtenwanne möglich.In addition, the press-in mandrel can have a groove on the circumference through which it engages the lamp tray can be locked. The press-in mandrel is advantageously shaped in such a way that it has a positioning and alignment to the recess of the lamp tray performs. This is an exact alignment of the bottom tray and so that the terminal attached to the lower trough or the Lower trough attached mounting frame opposite the recess in the Luminaire tray possible.

Eine besonders gute mechanische und elektrische Verbindung wird durch vier zueinander beabstandete Biegelaschen erzielt, wobei jeder Biegelasche eine Ausnehmung zugeordnet ist. Bei diesem Ausführungsbeispiel wird es bevorzugt, wenn zwei Biegelaschenpaare um 180 Grad versetzt zueinander angeordnet sind, so dass die Befestigung des Steuergerätes sowohl senkrecht zur Grundfläche der Trageinrichtung als auch parallel zur Grundfläche der Trageinrichtung optimal ist.A particularly good mechanical and electrical connection is made by four to each other spaced bending tabs achieved, each bending tab has a recess assigned. In this embodiment, it is preferred if two pairs of bending tabs are offset from each other by 180 degrees, so that the attachment the control unit both perpendicular to the base of the support device and is also optimal parallel to the base of the support device.

Sonstige vorteilhafte Weiterbildungen der Erfindung sind Gegenstand der weiteren Unteransprüche.Other advantageous developments of the invention are the subject of the others Dependent claims.

This has one extending from a base 24 radially inwardly extending radial web 26 to Center of the punch 22 towards a circular segment-shaped locking section 28 is expanded.

Gemäss der Darstellung in Figur 2 erstrecken sich die Biegelaschen 18a, 18b, 18c und 18d jeweils zu der benachbarten Seitenkante 30 bzw. 32 der Bodenplatte 16 hin nach außen - d.h. die Biegelaschen 18a, 18b sind gegenüber den Biegelaschen 18c, 18d um 180 Grad versetzt in der Bodenplatte 16 ausgebildet.As shown in FIG. 2, the bending tabs 18a, 18b, 18c extend and 18d towards the adjacent side edge 30 and 32 of the base plate 16, respectively to the outside - i.e. the bending tabs 18a, 18b are opposite the bending tabs 18c, 18d formed in the base plate 16 offset by 180 degrees.

In den Seitenkanten 30, 32 ist jeweils ein Langloch 34, 36 ausgebildet, über das eine zusätzliche oder alternative Fixierung des Gehäuses 6 erfolgen kann.An elongated hole 34, 36 is formed in each of the side edges 30, 32, via which one additional or alternative fixation of the housing 6 can take place.

Figur 4 zeigt eine Draufsicht auf den Boden 20 der Leuchtenwanne 4, wobei die Bodenplatte 16 des Gehäuses 6 des Vorschaltgerätes 2 gestrichelt eingezeichnet ist. Gemäss Figur 4 sind im Boden 20 vier runde Ausnehmungen 38a, 38b, 38c und 38d ausgebildet, die auch in Figur 2 teilweise sichtbar sind. Demgemäss liegen diese Ausnehmungen 38 konzentrisch zu den kreissegmentförmigen Verriegelungsabschnitten 28, so dass die Verriegelungsabschnitte 28 jeweils etwa die Hälfte der darunter liegenden Ausnehmung 38 überdecken. Der Durchmesser des etwa halbkreisförmigen Verriegelungsabschnittes 28 ist etwas geringer als der Durchmesser der zugeordneten Ausnehmung 38a bis 38d.Figure 4 shows a plan view of the bottom 20 of the lamp tray 4, the bottom plate 16 of the housing 6 of the ballast 2 is shown in dashed lines. According to FIG. 4 there are four round recesses 38a, 38b, 38c and 38d in the base 20 formed, which are also partially visible in Figure 2. Accordingly, these lie Recesses 38 concentric with the circular segment-shaped locking sections 28, so that the locking sections 28 each about half of those below cover recess 38. The diameter of the approximately semicircular Locking section 28 is slightly less than the diameter of the associated recess 38a to 38d.

Wie aus Figur 4 des weiteren entnehmbar ist, sind im Boden 20 des weiteren noch zwei Befestigungsbohrungen 40, 42 ausgebildet, die mit Bezug zu den Langlöchern 34 bzw. 36 ausgerichtet sind. Über die Langlöcher 34, 36 und die zugeordneten Bohrungen 40 bzw. 42 kann durch Einsetzen von Schrauben die zusätzliche oder alternative Befestigung des Gehäuses 6 an der Leuchtenwanne 4 erfolgen.As can also be seen from FIG. 4, there are still further in the bottom 20 two mounting holes 40, 42 formed, which are related to the elongated holes 34 and 36 are aligned. Via the elongated holes 34, 36 and the associated holes 40 or 42 can be the additional or alternative by inserting screws Attachment of the housing 6 to the lamp tray 4.

Zur Montage des Vorschaltgerätes 2 auf der Leuchtenwanne 4 wird dieses zunächst in die in Figur 1 dargestellte Relativposition zur Leuchtenwanne 4 gebracht, in der die Verriegelungsabschnitte 28 die darunter liegenden Ausnehmungen 38 im Boden 20 der Leuchtenwanne 4 abschnittsweise überdecken.To mount the ballast 2 on the lamp tray 4, this is first brought into the relative position shown in Figure 1 to the lamp tray 4, in the the locking sections 28 the underlying recesses 38 in the floor Cover 20 of the lamp tray 4 in sections.

Im nächsten Fertigungsschritt werden die Biegelaschen 18a bis 18d in der Darstellung gemäss Figur 1 nach unten gebogen, so dass die Verriegelungsabschnitte 28 in die jeweils zugeordnete Ausnehmung 38a bis 38d eintauchen und nach unten aus dem Boden 20 hervorstehen. Diese Montageposition ist in den Figuren 5 und 6 dargestellt, wobei beide Figuren einen vergrößerten Längsschnitt entlang der Linie A-A in Figur 2 darstellen. Demgemäss liegt der durch die Ausstanzung 22 gebildete Radialsteg 26 der Bodenplatte 16 des Gehäuses 6 auf einer benachbarten Grundfläche 44 des Bodens 20 der Leuchtenwanne 4 auf, während der kreissegmentförmige Verriegelungsabschnitt 28 um 90° nach unten gebogen ist und die Ausnehmung 38a durchsetzt. Dabei wird durch die sich vom Radialsteg 26 weg erstreckenden Rundschultern 46, 48 des Verriegelungsabschnitts 28 (siehe Figur 3) eine Hinterschneidung gebildet, die die untere Umfangskante der Ausstanzung 22 hintergreift, so dass die Bodenplatte 16 senkrecht zu der Grundfläche 44 lagefixiert ist. Die Lagefixierung in Querrichtung ist durch die jeweilige Anlage des Verriegelungsabschnittes 28 an der benachbarten Anlagefläche 52 der Ausnehmung 38a bis 38d gewährleistet.In the next manufacturing step, the bending tabs 18a to 18d are shown bent down according to Figure 1, so that the locking portions 28 in Immerse the respectively assigned recess 38a to 38d and downwards protrude from the floor 20. This assembly position is shown in FIGS. 5 and 6, both figures being an enlarged longitudinal section along the line A-A represent in Figure 2. Accordingly, the radial web formed by the punch 22 lies 26 of the base plate 16 of the housing 6 on an adjacent base surface 44 of the bottom 20 of the lamp pan 4, while the circular segment-shaped locking section 28 is bent downward by 90 ° and passes through the recess 38a. This is due to the round shoulders extending away from the radial web 26 46, 48 of the locking section 28 (see FIG. 3) an undercut is formed, which engages behind the lower peripheral edge of the punching 22, so that the base plate 16 is fixed in position perpendicular to the base surface 44. The fixation in Transverse direction is due to the respective contact of the locking section 28 on the adjacent contact surface 52 of the recess 38a to 38d guaranteed.

Die elektrische Verbindung zwischen der Bodenplatte 16 des Gehäuses 6 und dem Boden 20 der Leuchtenwanne 4 erfolgt durch die Anlage des Verriegelungsabschnitts 28 an den beiden Umfangskanten 50 der Ausnehmung 38a bis 38d. Die Biegelaschen 18a bis 18d und die Umfangskanten 50 der Ausnehmung 38a bis 38d liegen entlang der relativ scharfkantigen Umfangskanten aneinander, so dass eventuell vorhandene Beschichtungen, beispielsweise eine Lackierung der Leuchtenwanne 4 und des Gehäuses 6 durch den Biegeprozess und die aufeinanderstoßenden Umfangskanten durchbrochen und somit ein zuverlässiger Kontakt hergestellt wird. Diese Kontaktierung kann durch besonders scharfkantige Ausgestaltung der Anlageabschnitte noch verbessert werden. Üblicherweise werden die Bleche zur Herstellung der Bodenplatte 16 und des Bodens 20 vor dem Stanzen der Biegelaschen 18 und der Ausnehmungen 38 lackiert, so dass die Stanzkanten ohnehin unlackiert sind und somit die Kontraktierung keine Schwierigkeiten bereitet.The electrical connection between the base plate 16 of the housing 6 and the Bottom 20 of the lamp trough 4 is created by the installation of the locking section 28 on the two peripheral edges 50 of the recess 38a to 38d. The bending tabs 18a to 18d and the peripheral edges 50 of the recess 38a to 38d along the relatively sharp-edged peripheral edges, so that possibly existing coatings, for example painting the luminaire tray 4 and the housing 6 through the bending process and the abutting peripheral edges broken and thus a reliable contact is made. This Contacting can be achieved through a particularly sharp-edged configuration of the contact sections can still be improved. The sheets are usually used for production the bottom plate 16 and the bottom 20 before punching the bending tabs 18 and Recesses 38 painted so that the punched edges are unpainted anyway and thus the contracting presents no difficulties.

Das Umbiegen der Biegelaschen 18a bis 18d kann durch ein eigenes Werkzeug oder aber - wie in den Figuren 5 und 6 angedeutet - durch Integration eines Einpressdorns 56 in das Steuergerät 2 erfolgen, über die die Biegelaschen 18 in ihre dargestellte Verriegelungsposition bringbar sind. Diese Einpressdorne 56 können beispielsweise an der als Spritzgießbauteil ausgeführten Untersteckwanne 12 oder einem Montagerahmen ausgebildet sein, wobei die Anbindung - wie in Figur 5 angedeutet - über ein Filmscharnier 58 erfolgt, so dass die Einpressdorne 56 gegenüber der Untersteckwanne 12 bzw. dem Montagerahmen verschwenkbar sind. Die Einpressdorne 56 haben einen derartigen Querschnitt, dass sie in die Ausnehmung 38a bis 38d einschwenkbar sind und dabei den Verriegelungsabschnitt 28 der Biegelasche 18a bis 18d aus ihrer in Figur 1 dargestellten Grundposition (nach dem Stanzen) in die in Figur 5 dargestellte Verriegelungsposition bringen können. Je nach Anwendungsfall können die Einpressdorne 56 dann in ihrer unteren Schwenkposition durch eine Verriegelungsnut 54 arretierbar sein, so dass über diese Einpressdorne 56 der Verriegelungsabschnitt 28 gegen die Umfangswandung der zugeordneten Ausnehmung 38a bis 38d vorgespannt ist.The bending of the bending tabs 18a to 18d can be done using a separate tool or but - as indicated in Figures 5 and 6 - by integrating a press-in mandrel 56 in the control unit 2, via which the bending tabs 18 are shown in their Locking position can be brought. These press-in mandrels 56 can, for example on the bottom trough 12 designed as an injection molded component or a mounting frame be formed, the connection - as indicated in Figure 5 - via a Film hinge 58 takes place, so that the press-in mandrels 56 opposite the lower trough 12 or the mounting frame are pivotable. The press-in mandrels 56 have such a cross section that it can be pivoted into the recess 38a to 38d are and the locking portion 28 of the bending tab 18a to 18d from its basic position shown in FIG. 1 (after stamping) into the position shown in FIG Figure 5 can bring locking position shown. Depending on the application can then press the mandrels 56 in their lower pivot position by a locking groove 54 can be locked, so that the locking section via these press-in pins 56 28 against the peripheral wall of the associated recess 38a up to 38d.

Die Einpressdorne 56 besitzen eine angeformte Spitze 60 die beim Verriegelungsvorgang zuerst in den ausgestanzten Bereich zwischen Ausstanzung 22 und Biegelasche 18 und anschließend in die Ausnehmung 38 eingreifen, bevor sie die Biegelaschen 18 umbiegen. Dadurch wird eine Positionierung und Ausrichtung der Untersteckwanne 12 und somit der in die Untersteckwanne 12 eingesetzten Klemmenleiste 10 an den Ausnehmungen 38 des Bodens 20 der Leuchtenwanne 4 ermöglicht.The press-in mandrels 56 have an integrally formed tip 60 during the locking process first in the punched area between the punch 22 and the bending tab 18 and then engage in the recess 38 before the bending tabs 18 bend. This will position and align the lower trough 12 and thus the terminal block inserted in the lower trough 12 10 on the recesses 38 of the bottom 20 of the lamp tray 4 allows.
