Embodiment 1

[0040] The installation process of the pulse xenon lamp electrode connection device of this embodiment is as follows:

[0041] a. Use a torque wrench to connect the electrode to the electrode cap through threads, and the torque setting value is 17N·m~19N·m;

[0042] b. Cut the solder into solder pieces with a width of about 10mm to 15mm, and wrap them on the outer surface of the tail end of the quartz tube, and then insert the tail end of the quartz tube wrapped with the solder pieces into the annular groove of the electrode cap equipped with electrodes;

[0043] c. Put the quartz tube equipped with electrodes, electrode caps and solder vertically into a vacuum brazing furnace at a temperature not higher than 5×10 －3 Heating to above 600°C in a vacuum environment of Pa until the solder melts and fully reacts with the quartz glass, and the quartz tube and the electrode cap are directly welded into a whole;

[0044] d. After filling the quartz tube with a certain amount of xeno...

Abstract

The invention discloses an electrode connecting device for a pulse xenon lamp. The electrode connecting device is mainly composed of an electrode, an electrode cap, an adapter, a voltage equalizing cap, a cable wire and other components; and the components of the electrode connecting device are connected with one another in an orderly manner by means of interference fit connection, screw thread connection, screw fastening, crimping and brazing. According to the electrode connecting device for the pulse xenon lamp of the invention, the cleanness of the electrode and the electrode cap during theproduction process of the xenon lamp is ensured, so that the interior of the xenon lamp can be prevented from being contaminated; the assembling process of each component is simple and stable, and the structural strength of the components is high; and the connection area and cross-sectional area of each component are large, so that the components can withstand high current, and therefore, the service lives of the components can be significantly prolonged, and the operational reliability of the components can be improved.

Description

technical field [0001] The invention belongs to the technical field of electric light sources, and in particular relates to an electrode connection device for a pulse xenon lamp. Background technique [0002] High-power pulsed xenon lamps are widely used as pump light sources for large lasers. The peak current of the high-power pulse xenon lamp in normal operation reaches about 10kA to 25kA, and the peak current under the accelerated life working condition is even as high as 40kA or more. Therefore, the electrode connection device of the high-power pulsed xenon lamp should have a strong ability to withstand large currents and a high structural strength. [0003] The electrode connection device for the high-power pulse xenon lamp prepared by the transition glass sealing technology is simple. It is composed of electrodes, wire connectors and cables. And pour low-temperature solder into the through holes to solder them together. This structure is not suitable for high-temper...
