Abstract
A connection device (70) provides electrical connection between a stator motor (50) of an x-ray tube and a stator cord (56). The connection device is connected with the x-ray tube housing (30) by threading a threaded portion (80) into a corresponding threaded aperture (82) in the housing to create a leak-tight seal. The threaded portion is rigidly connected with a connecting portion (100), such as a bayonet socket, which receives a corresponding fitting (102) of the stator cord. An electrical conduction path (125), hermetically sealed in the connecting device, provides electrical connection between the socket and the interior of the housing. The connection device allows the stator cord to be quickly connected or disconnected from the housing yet provides a seal which resists leakage of cooling oil from the housing.
