In der FR-A-758644 ist eine elektrische Glühlampe mit Stromzuführungen offenbart, die in einen geformten Block aus transparentem Material eingelassen sind. Die Stromzuführungen sind mit äußeren Anschlüssen verbunden, wobei mindestens einer der Anschlüsse einen streifenförmigen oder flächig ausgebildeten Kontaktbereich aufweist, der sich über einen Teilbereich der Oberfläche des Blocks erstreckt.FR-A-758644 discloses an electric incandescent lamp with power supplies, which are embedded in a molded block of transparent material.

Eine weitere Aufgabe besteht darin Außenkontakte zu schaffen, die, auch bei Abweichung der räumlichen Anordnung der Gegenkontakte einer geeigneten Fassung von einer vorgegebenen Positionierung, eine ausreichende Kontaktgabe sicherstellen und somit relativ geringe Anforderungen an die Fertigungstoleranzen stellen. Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale des Anspruchs 5 gelöst. Weitere vorteilhafte Ausführungen der Erfindung sind in den darauf gerichteten Unteransprüchen erläutert.Another task is to create external contacts, even in the event of a deviation the spatial arrangement of the mating contacts of a suitable version of a predetermined positioning, ensure sufficient contact and thus make relatively low demands on the manufacturing tolerances. This task is according to the invention by the characterizing features of claim 5 solved. Further advantageous embodiments of the invention are in those directed to it Sub-claims explained.
Der erste Teil der Erfindung schlägt als Außenkontakte buchsenähnliche Klemmelemente vor. Ein Klemmelement besteht aus einem Anschlußteil, an dem eine Stromzuführung angeschlossen ist, und einem Klemmteil. Die Kontaktgabe mit einer Fassung wird durch Einstecken eines stiftartigen Steckelements, beispielsweise eines Drahtstücks oder eines Metalldorns in das Klemmteil hergestellt. Durch die Klemmwirkung des Klemmelements wird ein zuverlässiger Kontakt sichergestellt und gleichzeitig die Baueinheit in der Fassung fixiert.The first part of the invention proposes socket-like clamping elements as external contacts in front. A clamping element consists of a connecting part on which a power supply is connected, and a clamping part. The contact with a version is by inserting a pin-like plug element, for example one Wire piece or a metal mandrel made in the clamping part. Due to the clamping effect the clamping element ensures reliable contact and at the same time the unit fixed in the socket.
In einer bevorzugten Ausführung weist der Block an seiner Oberfläche Aussparungen auf, in welche jeweils ein Klemmelement eingesetzt ist. Der Anschlußteil ist dabei zumindest teilweise in den Block eingebettet, während sich der Klemmteil innerhalb der Aussparung erstreckt. Der Vorteil ist, daß das Klemmelement vor der Einwirkung äußerer Kräfte, etwa durch Stöße bei Handhabung oder Transport geschützt ist. Außerdem vergrößert sich die Gleitstrecke für Oberflächenentladungen, so daß die Betriebssicherheit erhöht ist.In a preferred embodiment, the block has cutouts on its surface on, in each of which a clamping element is inserted. The connector is there at least partially embedded in the block while the clamping part is within the recess extends. The advantage is that the clamping element before the action is protected from external forces, for example by shocks during handling or transport. In addition, the sliding distance for surface discharges increases, so that the Operational safety is increased.
In einer ersten Ausführung bestehen die Klemmteile jeweils aus mindestens zwei federnden Armen, die an ihren, in Richtung der Stromzuführung weisenden Enden mit dem Anschlußteil, z.B. einem Steg oder einer Platte verbunden sind. Die Arme sind so gekrümmt, daß das Klemmteil zwischen seinen Armen eine Engstelle aufweist. Durch Krümmung und Federkraft der Arme kann die Klemmwirkung gezielt beeinflußt werden. Die Aussparung bietet bei dieser Ausführung den weiteren Vorteil, daß eine Führung für die Steckanschlüsse einer Fassung gegeben ist und folglich ein Auswandern quer zu den sich gegenüberstehenden Armen verhindert wird.In a first embodiment, the clamping parts each consist of at least two resilient arms with the ends pointing towards the power supply the connector, e.g. are connected to a web or a plate. The arms are like that curved that the clamping part has a constriction between his arms. By The curvature and spring force of the arms can be influenced in a targeted manner. The recess in this embodiment has the further advantage that a guide is given for the plug connections of a socket and consequently emigration across the opposing arms is prevented.
In einer weiteren Ausführung bestehen die Klemmelemente jeweils aus einer topfartigen Hülse, deren Mantelfläche so geformt ist, daß die Hülse in ihrem Innern eine Engstelle aufweist. In a further embodiment, the clamping elements each consist of a pot-like one Sleeve, the outer surface of which is shaped so that the sleeve has a inside Has a constriction.
Der zweite Teil der Erfindung schlägt vor, daß ein oder mehrere der elektrischen Bauelemente in SMD-Technik ausgeführt sind, in den Block mindestens teilweise eingebettet sind und zusätzlich als Außenkontakte wirken, wobei jeweils eine der Anschlußflächen der SMD-Bauteile als Kontaktbereich dient.The second part of the invention proposes that one or more of the electrical Components are designed in SMD technology, are at least partially embedded in the block and also act as external contacts, one of the connection surfaces of the SMD components as the contact area serves.
In einer bevorzugten Weiterbildung ist zusätzlich ein Teilbereich der Oberfläche des Blocks konvex gekrümmt und mit einer elektrisch leitfähigen und spiegelnden Schicht oder Folie bedeckt, beispielsweise mit Gold bedampft. Diese Schicht dient als Außenkontakt und zusätzlich als optischer Reflektor, der die Lichtstärke auf der dem Reflektor gegenüberliegenden Sichtseite des Blocks erhöht.In a preferred development, a portion of the surface of the Blocks convexly curved and with an electrically conductive and reflective layer or foil covered, for example with gold. This layer serves as an external contact and in addition as an optical reflector that reflects the light intensity on that of the reflector opposite face of the block increased.
Der minimale Abstand zwischen den Außenkontakten beträgt bei einer Versorgungsspannung von 230 V typisch ca. 3 mm, um Oberflächenentladungen zu vermeiden. Um die Gleitstrecke zwischen den Außenkontakten zu vergrößern - ohne notwendigerweise die Außenabmessungen des Isolierstoffblocks vergrößern oder die Kontaktbereiche verkleinern zu müssen -, kann die Oberfläche zwischen den Außenkontakten eine, ggf. zusätzlich mit Rillen versehene Erhebung aufweisen.The minimum distance between the external contacts is at a supply voltage of 230 V typically approx. 3 mm to avoid surface discharges. In order to increase the sliding distance between the external contacts - without necessarily enlarge the outer dimensions of the insulating material block or the contact areas need to reduce the size - the surface between the external contacts have an elevation, optionally also provided with grooves.
Die Oberfläche des Isolierstoffblocks kann nahezu beliebig geformt sein, etwa völlig irregulär. Vorteilhaft ist sie mindestens im Bereich der Außenkontakte gleichmäßig geformt oder mit ebenen Abschnitten versehen. Geeignet sind insbesondere quader- oder zylinderförmige Bereiche, z.B. an einem oder beiden Enden des Isolierstoffblocks. Vorteilhaft ist der gesamte Block als geometrisch gleichförmiger Körper ausgebildet, z.B. als Quader oder Zylinder. The surface of the insulating material block can have almost any shape, for example completely irregular. It is advantageously uniform at least in the area of the external contacts shaped or provided with flat sections. Cuboid or cylindrical areas, e.g. at one or both ends of the insulating block. The entire block is advantageously designed as a geometrically uniform body, e.g. as cuboid or cylinder.
Die Außenkontakte bzw. ihre Kontaktbereiche bestehen aus einem elektrisch leitfähigen Material, z.B. aus einem Metall, etwa Kupfer, Gold, Silber oder einer Legierung.

3 eingreifen und auf diese Weise die beiden Kupferbänder 18a, 18b am
Kunststoffblock 3 fixieren. Der jeweils der Seitenfläche 19 zugewandte zweite Schenkel
182a, 182b der Kupferbänder 18a, 18b weist einen Abstand von der Seitenfläche
19 auf, indem er leicht gekrümmt ist. Dadurch federt dieser Teil bei Druckbelastung
mit einem Gegenkontakt und stellt so eine dauerhafte Kontaktgabe sicher.The
In Figur 3 ist der Längsschnitt einer weiteren Baueinheit 22 gemäß dem Stand der
Technik in schematischer Darstellung gezeigt. Im Unterschied zu derjenigen in Figur 2
weisen die Außenkontakte keinen Federbereich auf. Außerdem befindet sich auf der
quetschfußnahen Stirnseite 23 nur das mit dem Vorwiderstand 2 verbundene Kupferband
24a. Das zweite
Kupferband 24b ist symmetrisch bezüglich des Lampenkolbens 4 auf der pumpspitzennahen
Stirnfläche 25 angeordnet. Es ist im Bereich der pumpspitzennahen Vertiefung 17b
mit der Stromzuführung 26b verschweißt.In Figure 3 is the longitudinal section of a
Die Figuren 4a bis 4c zeigen eine Seitenansicht, eine Stirnansicht bzw. eine Draufsicht
einer Glimmlampe 1 mit zwei Vorwiderständen 27a, 27b in SMD(Surface Mounted
Device)-Technik, eingebettet in einem Kunststoffblock 28 mit teilweise metallisch
beschichteter Oberfläche 29.Figures 4a to 4c show a side view, a front view and a plan view of a
Der Kunststoffblock 28 weist eine im wesentlichen quaderähnliche Form auf, wobei
eine der Seitenflächen mit einer konvexen, in Stirnansicht rinnenähnlichen Krümmung
versehen ist. Auf diese gekrümmte Fläche ist eine dünne Nickelschicht 29 aufgedampft,
die als optischer Reflektor und gleichzeitig als zweiter Außenkontakt wirkt.
Um letzteres zu realisieren ist zunächst die erste Stromzuführung 30a mit der ersten
Anschlußfläche 31a des ersten Vorwiderstands 27a verbunden. Die gegenüberliegende
zweite Anschlußfläche 32a des ersten Vorwiderstands 27a schließt mit der sich an die
Krümmung anschließenden Seitenfläche des Blocks 28 ab. Sie ist von einer ebenfalls
metallischen Fortsatzfläche 33 überdeckt, die sich unmittelbar an die Längskante der
Metallschicht 29 anschließt und den elektrischen Kontakt zwischen Vorwiderstand
27a und Nickelschicht 29 sicherstellt. Die zweite Stromzuführung 30b ist mit der
ersten Anschlußfläche 31b des zweiten Vorwiderstands 27b verbunden. Die gegenüberliegende
zweite Anschlußfläche 32b des zweiten Vorwiderstands 27b schließt mit
der Oberfläche der quetschfußnahen Stirnseite 34 des Blocks 28 ab und wirkt als
zweiter Außenkontakt.The
