Description
Technical field
The present invention relates to capacitor design and manufacturing technology field, it particularly relates to a kind of novel non-solid electrolyte tantalum electrolytic capacitor.
Background technology
Along with electronic message unit constantly develops to miniaturization, digitized direction, the volume requiring the solid electrolyte Ta capacitor of present Metal Packaging constantly reduces, installation dimension constantly reduces, and product convenient fixing is reliable, to meet the needs of the device miniaturization such as Aeronautics and Astronautics, communication.Current non-solid electrolyte tantalum electrolytic capacitor is in actual use, due to reasons such as operational errors, the negative pole being easily caused non-solid electrolyte tantalum electrolytic capacitor bears forward voltage, if and negative pole bears forward voltage, electric current can flow to positive pole by negative pole, causing that capacitor reverse breakdown lost efficacy, electric current can sharply increase and burn capacitor simultaneously, causes greater loss.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of novel non-solid electrolyte tantalum electrolytic capacitor, the negative pole to solve existing non-solid electrolyte tantalum electrolytic capacitor bears forward voltage and causes capacitor reverse breakdown to lose efficacy and the technical problem that exists.
The present invention solves above-mentioned technical problem by the following technical programs:
A kind of novel non-solid electrolyte tantalum electrolytic capacitor, including housing, positive outside wire, plunger, ruthenium dioxide layer, anode tantalum fuse, retaining washer, negative outside wire and insulator, the one end open of housing, and the inwall of housing is coated with ruthenium dioxide layer, anode tantalum fuse is arranged in housing, plunger is arranged on shell nozzle end, and the two ends of plunger jointed anode tantalum fuse and insulator respectively, positive outside wire is connected on the tantalum pipe of insulator, retaining washer is arranged between housing and anode tantalum fuse, negative outside wire is connected to housing bottom, negative outside wire is provided with electronic device, this electronic device has the function of unidirectional conduction electric current.
Described electronic device is diode.
Described diode is any one in commutation diode, Zener diode, switching diode and isolating diode.
Described positive outside wire is that Plasma Welding is at insulator.
Described housing is cuboid or cylinder.
Described plunger is bonded on anode tantalum fuse by fluid sealant.
Being provided with groove, through hole and cannelure on described plunger, groove is arranged on the top of plunger, and through hole is arranged on the plunger below groove, and cannelure is arranged on plunger side.
Described positive outside wire is provided with electric fuse.
Described housing is silver shell.
The cross section of described insulator is convex.
The beneficial effects of the present invention is: diode has unilateral conduction, the present invention by after increasing diode on the cathode terminal of non-solid electrolyte tantalum electrolytic capacitor, when capacitor bears backward voltage, diode effectively stops and reverses current through capacitor, is reversed punctures inefficacy thus being prevented effectively from capacitor.It addition, the present invention arranges electric fuse on positive outside wire, it is possible to be prevented effectively from and burn out capacitor because the electric current in capacitor is excessive.
