Abstract

The utility model relates to an electrode of a neon lamp, which comprises a sealing guide wire, a heat isolating piece, an insulating piece, a cup-shaped electrode and a glass tube. The utility model is characterized in that the external surface of the cup-shaped electrode is wrapped by an oxide layer, and thus the utility model has the advantages of low cost, easy control of the process, no rust of the protected oxide layer, no sputtering occurrence, easy bombardment air removing function, etc.

Description

Neon tube electrode

The utility model relates to a kind of neon tube electrode.

Neon tube electrode is also referred to as the neon tube electrode chamber, electrode chamber is the critical piece of neon light, usually neon light is by electrode, the sealing-in seal wire, heat-barrier material (ceramic ring), insulating material (mica sheet), glass tube, the electronics bisque is formed, wherein the used material of electrode has copper, pure nickel, cast aluminium, pure iron and nickel-clad iron, wherein pure iron and nickel plating material have the life-span long, the fusing point height, cost is low, sputtering raste is little, processes means unanimity, so electrode high conformity, in lamp manufacturing process, degasification is more convenient easy to operate, but the pure iron electrode very easily gets rusty, and can cause the electrode emitting performance to descend; Nickel-plated iron electrode, its electroplating technology are difficult for grasping, and require overlay coating 8-10 μ degree layer thickness unanimity in electroplating technology, and nickel requirement based on very high purity, and coating is firm, otherwise will produce serious sputter, so nickel-plated iron electrode cost height, and electroplating technology is wayward.

The purpose of this utility model is to propose a kind of by sealing-in seal wire, heat shield, insulating trip, glass tube, electronics bisque with have the neon tube electrode that the electrode of pure iron oxide layer is formed; it not only manufacture craft control easily; protect oxide layer non-corrosive, no sputter; and easy bombardment characteristics such as degas, thereby solved the existing in prior technology problem.

The technical scheme that the utility model adopted is: it includes the oxide layer cup type electrode of wiring seal wire, heat shield, insulating trip, glass tube, electronics bisque and band pure iron; Wherein, this sealing-in seal wire, garden, the top arc outer surface welding of its middle part and cup type electrode, two ends of lead are as exit; This thermal insulation ceramics sheet, it is arranged on glass openend of type electrode, and this electronics bisque is to be attached to a glass type electrode inner wall, and this glass type electrode inner wall also can not apply the electronics powder; This glass type electrode is sealed in glass tube inside; This insulating trip places between glass type electrode and the glass tube, constitutes the utility model with this.

Advantage of the present utility model is that the oxidation technology cost is low, and is easy to control, protect oxide layer non-corrosive, no sputter, and easy bombardment characteristics such as degas, thus guaranteed the electrode chamber quality.

Fig. 1 is a structure chart of the present utility model.

Further specify preferred embodiment of the present utility model now in conjunction with the accompanying drawings, as shown in Figure 1, the utility model includes: sealing-in seal wire 1, and cup type electrode 3, glass tube 2, heat shield 4, electronics bisque 5 and insulating trip 6 are formed.Wherein said sealing-in seal wire 1, its middle part is welded on a glass type electrode garden cambered top end outer surface, and two ends of sealing-in seal wire extend in the outside of glass tube 2;

Said heat shield 4 is a potsherd 4, and it is arranged on glass openend of type electrode 3, and this electronics bisque 5 is to be attached to glass surface of type electrode inner wall; This glass type electrode 3 is sealed in the inside of glass tube 2; Said this insulating trip 6 is a mica sheet.Be set between glass type electrode 3 and the glass tube 2, constitute neon tube electrode with this, it is characterized in that said cup type electrode 3, its outer surface has an oxide layer, its manufacture craft is: the pure iron plate blanking, stretch, cut edge, clean, boronation is handled, be placed on that 12 station oxidation special equipment lists prop up or many in atmosphere, revolve round the sun by equipment in turn, the part rotating device is by 600 ℃ to 800 ℃ of the heating of the high pressure flame spray head on the equipment of being fixed on, 10-20 second, make pure iron anodizing surface form 5-50 μ oxide layer, overlap mica ring behind the natural cooling, ceramic ring plate roll extrusion is fixed, the pincers sealing connects lead-in wire, to constitute the utility model.
