DRIVING AND CONTROL DEVICE FOR A VACUUM PUMP, VACUUM PUMP, AND METHOD FOR PRODUCING A CONTROL CIRCUIT BOARD FOR A VACUUM PUMP

摘要

In a separating wall, which separates a vacuum region from a region under atmospheric pressure, pins are provided as a current lead-through. The pins are cast in, for example, glass. A plug-in contact is arranged on a separate carrier plate in order to prevent force or stresses, which can occur in particular because of tolerances, from being introduced into the glass. The carrier plate is connected to the control device by a flexible cable.

主权项

1. Driving and control device for a vacuum pump having
an electric device arranged in a vacuum region of a vacuum pump, a control device arranged outside the vacuum region of the vacuum pump, a separating wall for delimiting the vacuum region and a current lead-through arranged in the separating wall in a vacuum-tight manner and connected to the electric device via first current conductors and to the control device via second current conductors, wherein the second current conductor has a plug contact directly connected to the current lead-through, the plug contact, prior to assembly, being connected to the control device via at least one connecting web.
