Abstract
The utility model relates to a connector for high-pressure sodium lamps, which comprises a cup body part and an inserting part which are welded into one body. The utility model is characterized in that a spigot end of the inserting part corresponds to the diameter of a tungsten wire; the inserting part can be made of a niobium alloy wire, a niobium alloy band, and a niobium alloy cup; the niobium alloy wire, the niobium alloy band, and the niobium alloy cup which are welded together with a cup body are respectively formed into three kinds of forms, namely three kinds of connectors. The utility model has the advantages of simple technology operation, raw material saving, low cost, long service life, and 100 percent of yield.
Description
The utility model relates to light fixture, refers to the connector on a kind of high-pressure sodium lamp especially.
High-pressure sodium lamp is adopted widely as electric light source of new generation, and this is because it is compared with high-pressure mercury lamp with the incandescent lamp of present use, and it is long to have a life-span, saves series of advantages such as electric power and light are soft, is domestic and international a kind of electric light source of actively applying.
High-pressure sodium lamp is that sodium amalgam is luminous under high-tension electricity excites, and sodium at high temperature corrosivity is very strong, therefore adopts the connector of the niobium alloy of high temperature corrosion-resisting as the fixed tungsten electrode.Such as making connector with the niobium pipe with tungsten electrode fixedly the time, be that a end with the niobium pipe closes up with after the external diameter of tungsten electrode equates, tungsten electrode is inserted, and be that the not closing in end of niobium pipe is put into one section or several sections titanium silks in the other direction at it, make the titanium fusing through electron beam, tungsten electrode and niobium pipe are linked together securely, do not allow any slit, to prevent that at high temperature sodium vapor overflows.This process complexity, and during the molten titanium silk of weldering, because of niobium pipe diameter is very little, very easily puncture tube wall under electron beam causes increasing of waste and waste product, makes in this way rate of finished products only have 50% one 80% at present, the processing cost height, and lumber recovery is low.
The purpose of this utility model is at the problems referred to above, provides a kind of not only easy and simple to handle but also saves raw material, not only reduced cost but also improves connector on sodium vapor lamp a kind of high-pressure sodium lamp in useful life.
The purpose of this utility model is achieved in that the connector on a kind of high-pressure sodium lamp comprises inner cup portion and Plug Division, the cup end and the Plug Division of above-mentioned inner cup portion are welded as a whole, and the socket end of Plug Division is corresponding with the diameter of tungsten filament, and above-mentioned Plug Division can be niobium alloy silk, niobium alloy band, niobium alloy cup and makes.Constitute three kinds of forms that weld together with cup, three kinds of connectors respectively.
Advantage of the present utility model is:
1. adopt cheap niobium alloy by punching press or other pressure processing method moulding, the connector that constitutes after welding is compared with the niobium pipe of present employing, and cost is much lower.
2. connector and the shutoff of tungsten filament union end fundamentally stopped at high temperature to leak the possibility of sodium, thereby improved the useful life of sodium vapor lamp.
3. connector connects with tungsten filament by spot welding, has avoided adding titanium silk, with the loaded down with trivial details operation of electron beam welding, saved man power and material's consumption, puncture the possibility that tube wall is made waste product when having eliminated, make lumber recovery reach 100%, greatly reduced the cost of sodium vapor lamp because of electron-beam melting titanium silk.
The utility model further specifies by the following drawings and embodiment:
Fig. 1 is the utility model embodiment (one);
Fig. 2 is the utility model embodiment (two);
Fig. 3 is the left-hand view of Fig. 2;
Fig. 4 is the utility model embodiment (three).
Referring to Fig. 1-4: the connector on a kind of high-pressure sodium lamp comprises inner cup portion 1 and Plug Division 2, and the cup end and the Plug Division 2 of above-mentioned inner cup portion 1 are welded as a whole, and the socket end 3 of Plug Division 2 is corresponding with the diameter of tungsten filament.Above-mentioned Plug Division 2 can be niobium alloy silk 21, niobium alloy band 22, niobium alloy cup 23 and makes.Constitute three kinds of forms that weld together with cup 1, three kinds of connectors respectively.Above-mentioned cup 1 adopts the niobium alloy band to make the cylinder cup by punching press or other pressure processing method.
Referring to Fig. 1: the Plug Division 2 of above-mentioned niobium alloy silk 21 brake formings, its socket end 3 be between the alloy silk apart from e.During work, earlier be the bottom that the niobium alloy silk 21 of d is welded on cup 1, be bent into a Plug Division 2 then, and tungsten filament is inserted in back shutoff in the socket end diameter, then fundamentally stopped at high temperature to leak the possibility of sodium, thereby improved the useful life of sodium vapor lamp.
In like manner, referring to Fig. 2: the Plug Division 2 of above-mentioned niobium alloy band 22 brake formings, its socket end 3 be between the alloy band apart from e.Earlier be the bottom that the niobium alloy band 22 of b is welded on cup 1 during work, be bent into a Plug Division 2 then, and tungsten filament is inserted in the back shutoff get final product in the socket end 3 width.
In like manner, referring to Fig. 3: above-mentioned niobium alloy cup 23 stamping forming Plug Divisions 2 are a cup, and its socket end 3 is the inner diameter d of cup.The connected body of cup shape is welded on two cups of cup 1 bottom composition size, and tungsten filament is inserted in shutoff in the socket end, fundamentally stopped the possibility that high temperature leaks sodium down, avoid adding the titanium silk, loaded down with trivial details operation with electron beam welding, save human and material resources, improved lumber recovery, reduced cost.
