Protective device for solid electrolytic capacitor body

Abstract

The invention discloses a protective device for a solid electrolytic capacitor body. The protective device comprises a plurality of capacitor components which are arranged on an anode terminal and a cathode terminal in a laminated mode, wherein the plurality of capacitor components, the anode terminal and the cathode terminal are packaged and fixed by packaging materials such as synthetic resin and the like; and the packaging and fixing process comprises the following steps of: coating one or more layers of insulating glue on the capacitor body consisting of the plurality of capacitor components, the anode terminal and the cathode terminal to form an airtight protective layer; and packaging the capacitor body coated with the insulating glue by using the packaging materials. The protective device for the solid electrolytic capacitor body can overcome the defects that packaging pressure is high, the capacitor body is easy to damage, a short circuit and overhigh leakage current are easy to cause, and the like in the prior art, and has the advantages that: air tightness is high, the packaging pressure is low, the capacitor body is difficult to damage, and the short circuit and the overhigh leakage current are difficult to cause.

Description

technical field [0001] The present invention relates to the protection technology of capacitors, in particular to a protection device for a solid electrolytic capacitor body, in particular to a protection device that can reduce the pressure on the capacitor body when the packaging material is packaged, and avoid damage to the capacitor body due to excessive packaging pressure . Background technique [0002] In the existing technology, such as figure 1 and figure 2 As shown, the solid electrolytic capacitor 10 includes a multi-chip capacitor assembly 6 stacked in layers. At the bottom of the capacitor assembly 6 at the lowest level, an anode terminal 12 and a cathode terminal 13 are installed. The lower surface of the anode terminal 12 and the bottom surface of the cathode terminal 13 The bottom surface of the capacitor element 6 , the anode terminal 12 and the cathode terminal 13 are respectively covered with a synthetic resin 14 . [0003] Such as figure 2 As shown, i...

AI Technical Summary

Problems solved by technology

However, when encapsulating and covering the synthetic resin 14, the encapsulation pressure is still easy to damage the body of the capacitor assembly 6, causing short circuit and excessive leakage current. Therefore, how to improve the excessive encapsulation pressure problem in the prior art will be relevant. Issues that the industry needs to work on urgently
