Description
Technical field
The utility model relates to laser, particularly the radio frequency electrical feed through structures of laser.
Background technology
Gas laser generator is after utilizing a certain amount of Co2 gas, oxygen, nitrogen and other inert gas to mix in proportion, be filled with and taken out in the aluminium alloy laser cavity of ultra high vacuum degree in advance, by the discharge slat that feed-in optimal design in RF excited source is crossed, Co2 mixed laser gas generation glow discharge, discharge process is the transmittance process of an energy, and this process can produce the laser of high light beam quality.At present, many employing cermet soldering electricity feedthrough in laser, this electric feedthrough vacuum seal effect is poor, cause steam and pernicious gas to enter in laser cavity, and manufacturing cost is high, is not durable, and is not easy to batch production.The electric feedthrough of this mode is all fixed on above electrode, because electrode has heat to produce when electric discharge, electrode will be made like this to produce benefit of expanding with heat and contract with cold, because the length of electrode is long, electrode is easily out of shape, thus drives electric feedthrough to produce displacement, electricity feedthrough is moved and can be caused contacting with cavity, thus be short-circuited, cause whole laser circuit to be burnt, cannot normal operation.
Utility model content
For above-mentioned the deficiencies in the prior art part, the problem that the utility model solves is: provide that a kind of quality is high, the radio frequency electrical feedthrough of long service life, low cost.
For solving the problem, the technical scheme that the utility model is taked is as follows:
A floating type radio frequency electrical feedthrough for laser, comprises positioning element, floating member, Floating bolt, dead ring; Described positioning element is ∩ shape structure, and the top of positioning element is provided with floating hole; The elongated structure of described floating member, the longitudinal cross-section of floating member upper end is terraced structure, floating member is provided with internal thread hole, internal thread hole extends to the inside of floating member with one heart from the upper end of floating member, floating member is fit in the ∩ shape chamber of positioning element, the step surface of floating member upper end and the lower surface at positioning element top fit, and the step end of the upper end of floating member passes the floating hole of positioning element; Described step end and the floating distance in floating hole are 0.8 ~ 1mm; Described Floating bolt is connected with floating member threaded upper ends; Described dead ring is arranged on the outside of Floating bolt.
Further, the rounded shape in floating hole at described positioning element top, the cylindrical structure of step end of described floating member.
Further, the two bottom sides of described positioning element is vertically extended with fixing feet; Described fixing feet is provided with location hole.
Further, described step end and the floating distance in floating hole are 0.9mm.
The beneficial effects of the utility model
The utility model devises a kind of floating type radio frequency electrical feedthrough of laser of novel structure, positioning element and floating member are the main composition part of electric feedthrough, floating of 0.8 ~ 1mm distance can be produced between positioning element and floating member, positioning element is fixed on battery lead plate, because battery lead plate has heat to produce when electric discharge, battery lead plate will be made like this to produce effect of expanding with heat and contract with cold, because the length of battery lead plate is long, electrode is easily out of shape, the distortion of battery lead plate easily drives the movement of positioning element, when positioning element is moved, due to floating of 0.8 ~ 1mm distance can be produced between floating member and positioning element, so floating member can not be followed the movement of positioning element and move, thus avoid Floating bolt and produce short circuit with contacting of emission cavity shell, whole laser is caused to break down.Not only structure is simple, easily manufactured, cost is low in whole electric feedthrough, and the prolongation that the life-span of whole laser can be made to obtain, and greatly reduces spoilage.
