An x-ray source of the type used in medical or inspection devices having a first and second housing part which are detachably secured together to define an interior chamber for the housing. A plurality of power feeds is secured to the first housing part wherein each power feed has an elongated conductor extending into the chamber such that the conductors are parallel to each other. A removable cathode assembly includes a mounting plate having a plurality of tubular standoffs constructed of an electrically insulating material. These standoffs, furthermore, are secured to the mounting plate and protrude outwardly therefrom so that one standoff is associated with and registers with the conductor for each power feed. With the cathode assembly mounted in the housing chamber, the cathode assembly is secured to the housing by a threaded member extending through a cap secured to each standoff such that one end of the threaded member frictionally engages the conductor in its associated standoff thus securing the cathode assembly to the housing. |
