Abstract
The utility model provides a grid side-surface leading-out structure, and the structure is provided with a stem. A stem glass tube is disposed under the stem, and is connected with the stem in a sealing-in manner. A cathode lead is led out from the upper surface of the stem. The structure is characterized in that a grid lead wire is led out from the peripheral surface of the stem glass tube; and the grid lead wire is connected with the stem glass tube in a sealing-in manner. The structure provided by the utility model can improve the insulating performance, is low in leakage current between cathode grids, can improve the level of an electrical parameter of an electron tube.
Description
Technical field
The utility model relates to a kind of grid side utmost point deriving structure of electron tube.
Background technology
The grid deriving structure of existing electron tube is that cathode terminal and the grid lead wire of drawing by stem stem, by stem stem upper surface form.Because cathode terminal and grid lead wire are all positioned at stem stem upper surface, the two close together and wayward, thus cause its insulation degree low, produce between cloudy grid and have leakage phenomenon, reduce the electrical parameter level of electron tube.
Utility model content
Technical scheme to be solved in the utility model provides that a kind of to improve leakage current between insulation property, cloudy grid low and improve the gate side deriving structure of electron tube electrical parameter level.
Technical solution of the present utility model is:
A kind of gate side deriving structure, there is stem stem, below stem stem, be provided with stem stem glass-tube, described stem stem glass-tube and stem stem sealing-in, stem stem upper surface is drawn cathode terminal, its special character is: on described stem stem glass-tube external peripheral surface, draw grid lead wire, described grid lead wire and the sealing-in of stem stem glass-tube.
The beneficial effects of the utility model are:
Grid lead wire sealing-in, on the external peripheral surface of stem stem glass-tube, is increased to the distance between cathode terminal and grid lead wire, improved the insulation property between the two poles of the earth, reduced leakage phenomenon between cloudy grid, improved the electrical parameter level of electron tube.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-stem stem, 101-cathode terminal, 2-stem stem glass-tube, 3-grid lead wire.
Embodiment
As shown in the figure, the gate side deriving structure that the utility model relates to, there is stem stem 1, stem stem 1 is provided with stem stem glass-tube 2 below, described stem stem glass-tube 2 and stem stem 1 sealing-in, stem stem 1 upper surface is drawn cathode terminal 101, on described stem stem glass-tube 2 external peripheral surfaces, draws grid lead wire 3, described grid lead wire 3 and 2 sealing-ins of stem stem glass-tube.
Claims (1)
