ABSTRACT:

The invention concerns a process for production of a capacitor, in particular a vacuum capacitor, with cold-flow-extruded electrodes according to patent claim
1
, and a capacitor according to patent claim
7
.
Capacitors, in particular vacuum capacitors, for high-voltage ranges are known and, for example, find application in HF technology. The capacitor plates are generally each attached to a carrier part, this taking place, for example, through soldering. The two carrier parts are connected to the capacitor plates by means of an insulator, which is brought about through the same or a further soldering process. A rather expensive production method is required for this in order to meet the high demands with respect to the plate gap. Finally, the dimensional stability of the plate gap establishes the dielectric strength.
It is the task of the present invention to propose a process for production of a capacitor, in particular a vacuum capacitor, which process is simple to carry out and without problem meets the demands for dimensional stability in the plate gap. A further task of the present invention consists in proposing capacitors that are produced according to the process referred to.
According to the invention this task is accomplished with a process for a capacitor, in particular a vacuum capacitor, in which process each of the two electrode sets and the capacitor's holder for each set consist of a single piece, conforming to the wording of patent claim
1
, and with a capacitor produced according to this process, conforming to the wording of patent claim
7
.
