Abstract
The utility model relates to an electrode for a gas discharge lamp. The electrode comprises a core rod and a spring, wherein the spring is fixed on the core rod by laser spot welding, the spring is fixedly connected on one third to one fourth positions of the upper part of the core rod, and the laser welding spot is arranged on one fifth to one eighth positions of the lower part of the spring. Compared with the prior art, the electrode for the gas discharge lamp of the utility model has the beneficial effects that: the welding consistency is good, the product quality is assured, the welding electrode is not needed, worries about pollution or damage of the electrode are eliminated, the wastage and deformation of products can be minimized and the consistency of products is assured maximally since the manufacturing process of the electrode does not belong to touch-type welding process, and the strength of products after being burnt with hydrogen becomes stronger since the two objects are mutually melted after welding.
Description
Technical field
The utility model relates to a kind of electrode, especially relates to a kind of gaseous discharge lamp and uses electrode.
Background technology
The welding of electrode is to continue to use traditional electrode resistance welding always in the lamp; This technology adopts tungsten electrode discharge welding up and down; Being about to welded piece is pressed between two electrodes; And imposing electric current, resistance heat effect that workpiece contact-making surface and adjacent domain produce is heated fusing or mecystasis to utilize electric current to flow through, and makes it to form a kind of method of melts combine.Owing to receive influence of various factors, the product quality after its welding is difficult to be guaranteed, and the consistency of weld strength is very poor, has following shortcoming:
(1) the welding electrode contact-making surface is big, and the weldment position can not guarantee, the intensity that causes welding is very unstable.
(2) electrode surface needs frequent reconditioning because discharge generation is uneven.Can produce after electrode is discarded and pollute.
(3) after the annealing in hydrogen atmosphere in road was handled later, solder joint had obscission.
When (4) welding the small dimension product, because the extruding of upper/lower electrode can cause the distortion of product.
(5) welding energy changes, and causes the product embrittlement.
(6) single product is long weld time.
(7) product manual welding uses simple clamp tool can not guarantee the quality of welding.
The utility model content
The purpose of the utility model is exactly to provide a kind of high conformity, stay-in-grade gaseous discharge lamp to use electrode for the defective that overcomes above-mentioned prior art existence.
The purpose of the utility model can realize through following technical scheme:
Gaseous discharge lamp is used electrode, is made up of plug and spring, and described spring is fixed on the plug through laser spot welding, and spring is fixedly connected on 1/3-1/4 position, plug top, and the laser solder joint is located at 1/5-1/8 position, spring bottom.
The length of described plug is 4.5-15mm, and diameter is 0.5-1.2mm.
Described spring is made up of cycle spring assembly and inner ring spring assembly, and described cycle spring assembly is set in outside the inner ring spring assembly.
The length of described cycle spring assembly is the 2/3-3/4 of inner ring spring assembly length.
The diameter of described cycle spring assembly is 1.5-2 a times of inner ring spring assembly diameter.
Compared with prior art, the utlity model has following advantage:
(1) because laser energy is stable, product welding high conformity, quality is guaranteed;
(2) need not use welding electrode, not have electrode fouling or impaired misgivings, and because of not belonging to contact welding processing procedure, the consume of product and distortion connect can reduce to minimumly, has farthest guaranteed consistency of product;
(3) laser beam is easy to focus on, aims at and guide by optical instrument, can be placed on from the suitable distance of workpiece, and can between workpiece facility or obstacle on every side, guide again, can aim at weldment accurately;
(4) owing to weld the fusion each other of latter two article, the intensity of the product behind the annealing in hydrogen atmosphere improves.
