Abstract

1. Contact bracket for automatically making contact to, and breaking contact with, the product supports used in electroplating units, having a main body (1), a wedge-shaped clamping plate (2) and a compression spring (6) arranged between them, the wedge-shaped clamping plate (2) being arranged to slide at a wedge angle (4) on the main body (1), characterized in that the lower part of the wedge-shaped clamping plate is provided with a projection (3) whose upper surface (5) is of saddle-shaped construction.

Description

Kontaktbock für galvanische BäderContact block for galvanic baths

Es handelt sich um einen elektrischen Kontakthock aus Al oder Cu für galvanische Bäder, zur Kontaktierung von Warenträgern.It is an electrical contact stool made of Al or Cu for galvanic baths, for contacting goods carriers.

Die Kontaktböcke dienee zur elektrischen Stromübergabe an Träger die mit zu galvanisierender Ware (Teilen) bestückt bzw. beladen sind. hierbei muß sichergestellt sein, daß die Übertragung des elektr. Stromflusses vom Kontaktbock zum Warenträger, kraftschlüssig und mit geringstmöglicher Wärmeentwicklung erfolgt.The contact blocks serve for the electrical current transfer to carriers which are equipped or loaded with goods (parts) to be galvanized. it must be ensured that the transmission of the electr. Current flow from the contact block to the goods carrier, non-positively and with the least possible heat development.

Bekannte Ausführungen sind:

  • Aus einzelnen Kontaktlamellen bestehende Böcke, wobei die Lamellen durch Federdruck gegen den Warenträger gepresst werden. Kontaktböcke mit feststehenden Zungen, in die einzelne mit Federdruck arbeitende Kontaktbolzen eingesetzt sind. Kontaktböcke mit pneumatisch oder hydraulisch gesteuerten Exzentern oder Druckplatten sowie Sattelkontaktböcke mit prismenartiger Auflage.
Known designs are:
  • Bocks consisting of individual contact lamellae, the lamellae being pressed against the goods carrier by spring pressure. Contact blocks with fixed tongues, in which individual contact bolts working with spring pressure are inserted. Contact blocks with pneumatically or hydraulically controlled eccentrics or pressure plates as well as saddle contact blocks with prism-like supports.

Durch Einfluß von Badchemikalien und Wärme sind bewegliche Teile und mechanische Geräte erheblichem Verschleiß unterworfen, der die Kontaktfähigkeit mit der Zeit stark beeinträchtigt und so zu einer weiteren Zunahme der Erwärmung führt.Due to the influence of bath chemicals and heat, moving parts and mechanical devices are subject to considerable wear, which severely impairs their ability to make contact over time and thus leads to a further increase in heating.

Die Erfindung ist das Ergebnis der Suche nach einer einfachen Lösung, für eine einwandfreie, problemlose Kontaktierung, die durch die kennzeichnenden Merkmale des Anspruchs l.bis 4. gegeben ist.The invention is the result of the search for a simple solution, for a flawless, problem-free contact, which is given by the characterizing features of claims 1 to 4.

rm Sinne einer einwandfreien Funktion, müssen die Dimensionen des Kontaktbockes auf die Abmessungen des Kontaktkopfes der jeweiligen Warenträger abgestimmt sein. Für die Erzielung einer optimalen Verbindung, bedarf es keiner zusätzlichen manuellen oder steuerungstechnischen Maßnahmen. Die Erwärmung wird auf ein Minimum begrenzt. Durch einsetzen oder anheben der Warenträger wird die Verbindung automatisch hergestellt bzw. gelöst. Aus diesem Grunde eignet sich der Kontaktbock insbesondere auch für vollautomatisch gesteuerte Galvaniken.In order to function properly, the dimensions of the contact block must be matched to the dimensions of the contact head of the respective goods carrier. No additional manual or control measures are required to achieve an optimal connection. Warming is kept to a minimum. The connection is automatically established or released by inserting or lifting the product carrier. For this reason, the contact block is particularly suitable for fully automatically controlled electroplating.

Das in der Zeichnung dargestellte Ausführungsbeispiel wird wie folgt beschrieben:

  • Der Kontaktbock(l) als Grundkörper ist mit der elektr. Stromzuführung verbunden. Die Keilspannplatte(2) wird durch Federdruck(6) in ihrer Ausgangsstellung gehalten. Bei aufsetzen des Warenträgers auf die Keilspannplattennase(3) wird die Keilspannplatte(2) gegen den Federdruck(6) nach unten gedrückt, so daß infolge der in einem entsprechenden Winkel verlaufenden Gleitfläche(4), durch das Eigengewfcht des Warenträgers, eine kraftschlüssige Verkeilung bzw. Kontaktierung erfolgt. Beim Anheben des Warenträgers wird die Keilspannplatte(2) mittels Federdruck(6) in Richtung Ausgangsposition zurückgeschoben, so daß sich die Kontaktierung von selbst löst.
The embodiment shown in the drawing is described as follows:
  • The contact block (l) as the main body is with the electr. Power supply connected. The wedge clamping plate (2) is held in its starting position by spring pressure (6). When the product carrier is placed on the wedge clamping plate nose (3), the wedge clamping plate (2) is pressed downwards against the spring pressure (6), so that due to the sliding surface (4) running at an appropriate angle, a forceful wedging or Contact is made. When the product carrier is lifted, the wedge clamping plate (2) is pushed back in the direction of the starting position by means of spring pressure (6), so that the contact is released automatically.

Mit der sattelförmigen Ausführung(5) der Keilspannplattennase(3) wird erreicht, daß Differenzen an den Kontaktflächen der Warenträger ausgeglichen werden. hierfür ist die Führung der Keilspannplatte(2) so gewählt, daß diese in ihrer Querachse ausschwenken kann.With the saddle-shaped design (5) of the clamping plate nose (3) it is achieved that differences on the contact surfaces of the goods carriers are compensated for. For this purpose, the guide of the wedge clamping plate (2) is selected so that it can swing out in its transverse axis.
