Abstract
The utility model discloses a composite energy-saving electron gun cathode which structurally comprises an electric heating plate and a cathode base metal coated by carbonate cathode powder; the electric heating plate is inverted U-shaped, the cathode base metal is sheet-type, and one surface of the cathode base metal is not coated by the carbonate cathode powder and is fixed in the center of the top end of the electric heating plate. The composite energy-saving electron gun cathode can effectively reduce the energy consumption of the electron gun cathode and greatly saves the energy source.
Description
Technical field
The utility model relates to a kind of gun cathode, especially a kind of be applied in monochromatic show on the electron gun, Remarkable Energy Saving combined type energy-saving gun cathode.
Background technology
The existing monochromatic negative electrode of electron gun that shows comprises cathode base metal, negative electrode inner sleeve and the heating wire that is coated with carbonate negative electrode powder, the cathode base metal is the cap shape, be enclosed within negative electrode inner sleeve top, heating wire is positioned at negative electrode inner sleeve inside, be the cathode base metal heat supply, to excite the carbonate negative electrode powder emitting electrons on the cathode base metal; The diameter of cap shape cathode base metal is 1.5mm, the top of the spraying scope covering cap shape cathode base metal of carbonate negative electrode powder, thus its spraying diameter also is 1.5mm, the sheet thicknesses of cathode base metal is 0.11mm.This design is owing to the negative electrode inner sleeve of being separated by between heating wire and the cathode base metal, and the efficiency of heating surface is low, wastes energy.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of combined type energy-saving gun cathode, can effectively reduce the energy consumption of gun cathode.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of combined type energy-saving gun cathode, comprise in the structure that electric heating piece and its go up the cathode base metal that simultaneously is coated with carbonate negative electrode powder, electric heating piece is inverted U, the cathode base metal in the form of sheets, the one side that the cathode base metal is not coated with carbonate negative electrode powder is fixed on the top central authorities of electric heating piece.
The cathode base metal is the disk shape, and the diameter of disk is 0.68-0.8mm, and the thickness of disk is 0.04-0.06mm.
The spraying scope of carbonate negative electrode powder on the cathode base metal is a circle concentric with the cathode base metal, and circular diameter is 0.55-0.63mm.
The one side that the cathode base metal is not coated with carbonate negative electrode powder is fixed by welding in the top central authorities of electric heating piece.
Adopt the beneficial effect that technique scheme produced to be: owing to directly be weldingly fixed on the cathode base metal on the electric heating piece, the efficiency of heating surface height of electric heating piece target Base Metal, thereby under the prerequisite that guarantees the electron gun operate as normal, can do the cathode base metal littler and spraying scope thinner, carbonate negative electrode powder also can be littler, reach energy-conservation effect; Because the cathode base metal is the disk shape, the diameter of disk is 0.68-0.8mm, and thickness is 0.04-0.06mm, is that 1.5mm, thickness are that the cap shape cathode base metal of 0.11mm is compared with the past diameter, operating voltage becomes present 0.6V by original 12V, has saved the energy greatly; Because the spraying diameter of carbonate negative electrode powder becomes present 0.55-0.63mm by original 1.5mm, has further saved the energy.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structure cutaway view of an embodiment of the utility model;
Fig. 2 is the partial enlarged drawing of Fig. 1 in the cathode base metal part.
Embodiment
Referring to accompanying drawing 1.2, comprising the electric heating piece 1 that is inverted U in the structure of a specific embodiment of the utility model and being coated with carbonate negative electrode powder 3, that be the disk shape, diameter is that 0.72mm, thickness are the cathode base metal 2 of 0.05mm, the one side that cathode base metal 2 is not coated with carbonate negative electrode powder is weldingly fixed on the top central authorities of electric heating piece 1, the spraying scope of carbonate negative electrode powder 3 on cathode base metal 2 is a circle concentric with cathode base metal 2, and circular diameter is 0.6mm.
During use, electric heating piece 1 is fixed on the holder to be assembled on the electron gun, can as existing gun cathode, uses, can save the energy greatly.
