Problems solved by technology

like figure 1 As shown, since the all-tantalum capacitor can only be directly installed on the printed circuit board, it is necessary to bend the all-tantalum capacitor during installation, and manually solder and fix it on the surface of the PCB with a soldering iron. More tantalum electrolytic capacitors are required for combination when the power is 1 watt, and the design and installation of its own printed circuit board cannot meet the miniaturization requirements of satellite space, which restricts its application range

specific Embodiment

[0071] The tantalum capacitor in this embodiment is a CAK38-125V-82uF-K axial non-solid electrolyte all-tantalum capacitor.

[0072] Step 1: Take 16 tantalum capacitors 1, and trim the positive and negative pins of each tantalum capacitor so that the length of the trimmed pins is 3mm, and the solder joints on the positive pins cannot be damaged when trimming ;

[0073] Step 2: If Figure 5 with 6 As shown, according to the principle that the same polarity is on the same side, the trimmed 16 tantalum capacitors are stacked into a two-layer and two-column structure. In this structure, there are 8 tantalum capacitors in each layer and 8 tantalum capacitors in each column; The homopolar pins on the left side of the structure follow the Figure 5 The method shown is welded on a silver-plated copper wire with a diameter of 0.7mm. After welding, the silver-plated copper wire forms an inverted "mesh" structure. Figure 4 The method shown is welded on a silver-plated copper wire wi...

Abstract

The invention provides a pulse energy storage capacitor packaging method and packaging structure, belonging to the energy storage capacitor technology field. The pulse energy storage capacitor packaging method comprises steps of arranging a plurality of pulse energy storage capacitors together and connecting and fixing the plurality of pulse energy storage capacitors in parallel to form a pulse energy storage capacitor set, and arranging at least one positive electrode terminal lead and at least one negative electrode terminal lead for the capacitor set, packaging the pulse storage energy capacitor set inside a packaging housing through a glue solution for potting, wherein the positive electrode terminal lead and the negative electrode terminal lead are left outside of the packaging housing. The pulse energy storage capacitor packaging method and packaging structure can arrange a single pulse energy storage capacitor, can package the plurality of arranged pulse energy storage capacitors, can connect the pulse energy storage capacitor set to other members through the positive electrode terminal lead and the negative electrode terminal lead which are exposed outside, and can fix thepackaging housing through a fixing member. The pulse energy storage capacitor packaging method and packaging structure realize three-dimensional spatial arrangement of the pulse energy storage capacitors, improve a space utilization rate, simplify a fixation mode of the capacitor, make the pulse energy storage capacitor barely be under stress, and greatly improve safety and reliability of operation of an amplifier.

Description

technical field [0001] The invention relates to a secondary packaging method and packaging structure of a space-use pulse energy storage capacitor, belonging to the technical field of energy storage capacitors. Background technique [0002] The pulse traveling wave tube amplifier has the advantages of high efficiency, light weight and low cost, and is widely used in radar satellites. Its main function is to amplify the pulse power of the downlink signal of the user link, and at the same time adjust the amplitude and phase of the radio frequency channel. Send it to the rear antenna subsystem. In order to realize the normal operation of the radio frequency link in the pulse traveling wave tube amplifier, the traveling wave tube power supply requires a stable output of hundreds of watts for the changing power. The power supply must use an electronic power conditioner (EPC) to step down the primary bus of the satellite. , to meet the voltage and current requirements required by...
