This invention belongs to the field of
titanium sublimators, specifically a
ceramic-sealed
electrode structure for
titanium sublimators. It includes a
guide tube, a sealing
flange, a cap, three conductive electrodes made of
titanium-
molybdenum wires, and a common
electrode. The three conductive electrodes and the common
electrode are arranged circumferentially along the cap and fixedly connected to it. The cap is fixed inside the sealing
flange, and the
guide tube is fixed to one side of the sealing
flange. The conductive electrodes of the titanium-
molybdenum wires include a titanium wire support rod, an upper cap, a
ceramic tube, and a lower cap. The
ceramic tube is connected to the upper and lower caps on both sides, respectively. The lower cap is fixed inside the cap. The titanium wire support rod passes through the upper cap, the ceramic tube, and the lower cap, and is fixedly connected to the upper cap. The common electrode includes a ground cap and a
ground support rod. The ground cap is fixed inside the cap, and the
ground support rod passes through the ground cap and is fixedly connected to it. This invention can prevent deformation of the
ground support rod and titanium wire support rod caused by the heating of the titanium-
molybdenum wires, avoiding poor contact with the
power cable due to deformation of the titanium sublimator connector.
