Abstract: A cathode structure of a thermal electron emitting cathode of an electron tube, particularly of a magnetron for preventing the damage and break due to mechanical vibration of the cathode. A spacer is interposed in a space between a center lead and a lower end shield to prevent the vibration through the center lead. The antivibration effect of the filament cathode is attained by arranging the spacer having an aperture through which the center lead and a side lead extend such that the spacer contacts to an inner wall of a shielding member which constitutes a portion of a vacuum envelope of the magnetron.

Abstract: In a cathode for a heavy-duty electron tube, the cathode wires (5) lying on the surface (11) of a cylinder between two rigidly constructed connector rings (7, 8) have the form of a surface line with changing pitch. The cathode wires are connected by a support ring (6). The thermal expansion of the cathode wires during operation results only in a shifting on the surface (11). In this manner the cylindrical shape of the cathode and thus the distance to the control grid are maintained without the expensive spring suspension device used in the cage cathode.

Abstract: One end of an electrode wire is doubled back at least once forming a teardrop shaped loop around a connector with the terminal end of the wire placed adjacent the wire inwardly of the connector. A rounded conductive mass encapsules said terminal end and the wire. This mass suppresses the field generated at the terminal end of the wire, provides mass dampening inwardly of the connector and distributes the load over both sides of said teardrop shaped loop. A converging restraining means may be disposed over and in contact with both sides of said loop intermediate said mass and said connector thereby providing additional dampening and an ultimate limit on loop movement. The connector has a circular groove within which the base portion of the loop is tightly accommodated by crimping the connector thereover. Preferably, the connector should be constructed from a metal having a substantially lower modulus of elasticity than the wire to preserve the cross-sectional stress area of the wire in so crimping.
