Abstract
The utility model discloses an inserting embedded butt welding structure of the electrode of a ceramic metal halide lamp. An electrode main rod is used as a tungsten electrode main rod, a molybdenum electrode main rod, a tungsten alloy electrode main rod or a molybdenum alloy electrode main rod, a leading-out rod is a niobium leading-out rod or a niobium zirconium alloy leading-out rod, one end of the electrode main rod is inserted into the end surface of the leading-out rod, and the outer wall of the inserting end of the electrode main rod is welded and connected with the end surface of the leading-out rod. The utility model has the advantages that the structure is reasonable, the electrode main rod is fully melted and combined with the grain boundary of the niobium leading-out rod, a molybdenum bush and a tungsten tungsten rod are in seamless and gapless connection, the welding point has high strength, and no broken two-segment phenomenon is caused in 90-degree folding. As the tungsten electrode main rod and the niobium leading-out rod are perfectly and tightly connected, the consistence of the resistance of the product is ensured to be very high, so that the defect that due to the problems of rough and uneven spot welding, hollowing, insufficient welding and the like of the current laser welding, quality potential of air leakage is caused when the electrode is connected with a ceramic pipe in a sealing way can be avoided.
Description
Technical field
The utility model relates to a kind of ceramic metal halogen lamp pole structure.
Background technology
Ceramic metal halogen lamp pole is taked traditional laser welding mode in the prior art, as shown in Figure 1: when electrode mobile jib 1 and leading-in pole welding junction place two nose circle contact-making surfaces can not guarantee perfect 90 ° of right angles, the end is bound to gapped, at this moment Laser Welding can only reach melt surface, if and the employing high power laser is soldered to the center, its result sandwiches air because metal can be spoilt sunken reaching in the quick flow process of niobium liquation because of the effect of gravity when reaching fusing point, can't reach the butt joint effect, so in order to keep the reset condition on surface, laser can only melt knot in shallow surface, have following result: 1, contact layer density when both ends of the surface are closed up can't reach the density of metal metallographic intergranular combination, cause resistance value big, logical for a long time can the heating when impacting therebetween of electric current (can expand when accepting heat owing to residual air; When 2, there is big gap at two ends since around wrap, the air in the middle space runs into heat and can produce blast.
Summary of the invention
The purpose of this utility model is the Laser Welding shortcoming that has the ceramic metal halogen lamp pole complexity now in order to overcome, and the ceramic metal halogen lamp pole of good working effect inserts inserted to welding structure.
The technical solution adopted in the utility model is:
A kind of ceramic metal halogen lamp pole inserts inserted to welding structure, comprise electrode mobile jib and leading-off rods, described electrode mobile jib is tungsten electrode mobile jib, molybdenum electrode mobile jib, alloyed tungsten electrode mobile jib or alloy molybdenum electrode mobile jib, described leading-off rods is niobium leading-off rods or niobium zirconium alloy leading-off rods, it is characterized in that: an end of described electrode mobile jib inserts in the end face of described leading-off rods one end, and the outer wall of electrode mobile jib insertion end and leading-off rods end face are welded to connect.
Leading-off rods and electrode mobile jib plugging position surface are expands upwards, and leading-off rods expansion place diameter is than the big 0.02mm ~ 0.2mm of leading-off rods position diameter.
The insertion end of electrode mobile jib is the chamfering form.
The utility model is rational in infrastructure, and the electrode mobile jib combines with niobium leading-off rods crystal boundary full-fusing, and molybdenum cover and the seamless no gap of tungsten zirconium bar, and Joint Strength height are rolled over 90 ° of no dialysis and divided two sections phenomenons.Because tight between tungsten bar and the niobium bar perfectly is connected, and guaranteed that product resistance consistency is very high; Thereby the hidden danger of quality that has leaked gas when having avoided present Laser Welding to cause electrode and earthenware sealing-in effectively because of problems such as solder joint is rough and uneven in surface, hollow, rosin joints.
The utility model has solved following several shortcomings of traditional electrode with inserted mode.
1, fragility is big in various technical processs, intensity is low for the strength laser welding electrode, thoroughly fragments into two sections at 45 ° when crooked.
2, middle residual air has expand aging or hidden peril of explosion.
3, the recessed injustice of spoiling of solder joint, the even dense distribution of the scolder when having a strong impact on the fluorescent tube sealed knot and produce gas leakage makes fluorescent tube die young in early days (common deficiency).
