Description
Die Erfindung betrifft einen Kollektor einer el*i;tronischen Maschine, insbesondere eines Trommelkollektors oder Planke?- lelktors, Kit einem Kollektorkörpar acss «liner Kunststoff-Pr&Smasse und mit einer aktiven Kollektorfläche mit einer segmentierten Metallauflage, vorzugsweise aus Kupfer, an Ssgseaten <*"* i**rtrische Ansch!ußl<fei*-er vorgesehen sind,The invention relates to a collector of an electronic machine, in particular a drum collector or plank collector, with a collector body made of a plastic preform and with an active collector surface with a segmented metal coating, preferably made of copper, on which electrical connection leads are provided,

Ein derartiger, als Plankollektor ausgebildeter Kollektor ist Gegenstand rtes Alteren Gebrauchsmusters G 89 07 045.3. Die Kohlenstoffauflage ist dort dadurch formschlüssig mit den Metallsegmenten verbunden, daß in der Oberseite der Metallsegmente schvalbenschwanzförmige Aufnahmen ausgebildet sind, die mit dem Material der Kohlenstoffauflage gefüllt sind. Die Herstellung dieses Verbuncliicörpers, bestehend aus den Metallsegmenten mit den mit ihnen formschlüssig verbundenen 25 Kohlenstoff auf lagen ist daher verhältnismaBig arbeitsintensiv.Such a collector, designed as a flat collector, is the subject of the older utility model G 89 07 045.3. The carbon layer is connected to the metal segments in a form-fitting manner by forming dovetail-shaped recesses in the top of the metal segments, which are filled with the material of the carbon layer. The production of this composite body, consisting of the metal segments with the 25 carbon layers connected to them in a form-fitting manner, is therefore relatively labor-intensive.
Ausgehend von diesem Stand der Technik liegt daher der Erfindung die Aufgabe zugrunde, einen Kollektor mit den eingangs genannten Merkmalen vorzuschlagen, der eich besonders 3Q einfach und mit wenigen Verfahrensechritten und somit kostengünstig herstellen läßt.Based on this state of the art, the invention is therefore based on the object of proposing a collector with the features mentioned at the beginning, which can be manufactured particularly easily and with few process steps and thus cost-effectively.
Zur Losung dieser Aufgabe ist die Erfindung dadurch gekennzeichnet, das die zu der Kohlenstoff auf lage weisende Oberfl A-ehe der Metal 1 segmente mit Vorsprüngen versehen ist, von denen Teile seitlich über die Füße der Vorsprünge vorstehen und daßTo solve this problem, the invention is characterized in that the surface of the metal 1 segments facing the carbon layer is provided with projections, parts of which protrude laterally beyond the feet of the projections and that

Durch diese Maßnahmen wird auf arbeitstechnisch einfache Weise ein Verbundkörper, bestehend aus den Metallsegaenten sit ihren Kohlenstoff auf lagen geschaffen, wobei der Verbundkörper allen im Betrieb ausgesetzten Belastungen ausgezeichnet, standhält. Dies beruht darauf, daß das Kohlenstoff material durch die entsprechend profilierten und geformten Vorsprünge der Metallsegmente fest und unverlierbar mit dem Material derThese measures create a composite body consisting of the metal segments with their carbon layers in a technically simple manner, whereby the composite body can withstand all the stresses it is exposed to during operation. This is due to the fact that the carbon material is firmly and permanently bonded to the material of the

Das Material um die Spitzen 2 und auch über diesen Spitzen wird mit dem Material einer geeigneten Kohlenstoffauflage 3 ausgefüllt, wobei das Graphit-oder Kohlenstoffmaterial durch ein geeignetes Preßverfahren mit dem Material der Metallauf lage 1 unverlierbar verbunden wird.The material around the tips 2 and also above these tips is filled with the material of a suitable carbon coating 3 wherein the graphite or carbon material is permanently bonded to the material of the metal coating 1 by a suitable pressing process.
Eine andere Ausführungsform zeigt Fig. 2, wo die Vorsprünge 2 pilzförmige ausgebildet sind.Another embodiment is shown in Fig. 2, where the projections 2 are mushroom-shaped.
Die pilzförmigen Vorsprünge nach Fig.2 können beispielsweise dadurch hergestellt werden, daß die Oberfläche der Metallauflage 1 gerändelt und gekordert wird. Dadurch ergibt sich ein rhombenförmiges Muster von Erhebungen auf der Oberfläche der Metallauflage 1. Anschließend werden die Spitzen dieser Erhebungen gestaucht, wodurch sie die Pilzform annehmen.The mushroom-shaped projections according to Fig. 2 can be produced, for example, by knurling and knurling the surface of the metal layer 1. This results in a rhombus-shaped pattern of elevations on the surface of the metal layer 1. The tips of these elevations are then compressed, whereby they take on the mushroom shape.

Bezüglich der Einzelheiten des Kollektorbereichs, in dem die Schichten 1, 3 mit Hilfe der Vorsprünge 2 miteinander verankert sind, sowie des übrigen Aufbaus eines Plankollektors, wird beispielsweise auf die eingangs erwähnte deutsche Gebrauchsmuster schrift 89 07 045.3 verwiesen,, die Plankollektoren in mehreren Ausführungsformen zeigt. Trommelkollektoren nach der Erfindung sind entsprechend aufgebaut.Regarding the details of the collector area, in which the layers 1, 3 are anchored together with the help of the projections 2, as well as the remaining structure of a flat collector, reference is made, for example, to the German utility model 89 07 045.3 mentioned at the beginning, which shows flat collectors in several embodiments. Drum collectors according to the invention are constructed accordingly.
