In gap of anode Tanzania block and tube filled with electrolyte. The advantages are stable, the long service life of no-damage.
Description
Technical field: the present invention relates to a kind of electrolytic capacitor, relate in particular to a kind of high backward voltage resistance capacitor.
Background technology: at present, the typical structure of capacitor is an encapsulation anode tantalum capacitor in silver-colored shell, and directly with the negative electrode of silver-colored shell as capacitor.Though this design is simple, have following defective: when applying reverse voltage, argent can be dissolved in the electrolyte, and is deposited on anode surface; When applying forward voltage again, just can produce bigger leakage current or cause short circuit.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the present invention aims to provide a kind of high backward voltage resistance capacitor that can bear big reverse voltage in a long time.
Technical scheme of the present invention comprises shell, anode tantalum piece, electrolyte and cathode and anode lead-in wire, and an end is fixed with in cathode leg, the tantalum shell of the other end by the stick harness sealing negative electrode tantalum tube is housed, and the anode tantalum piece that is with the insulation underlay is installed in this tube; The tantalum wire that is inserted in the anode tantalum piece passes from stick harness, and fixedly docks with anode tap; Electrolyte is loaded in gap between anode tantalum piece and negative electrode tantalum tube.
The glass insulator sealing that the port of tantalum shell is made of glass insulator, tantalum pipe and tantalum ring; The tantalum wire that passes from stick harness passes the tantalum pipe and fixedly docks with anode tap, and with the ferrule of tantalum pipe; Between anode tantalum piece and stick harness, pad is housed, is with the O RunddichtringO in the outer ring of stick harness.
Compared with the prior art, the present invention is owing to increased a negative electrode tantalum tube on the basis of traditional electrical electrolysis condenser, thereby improved the ability that capacitor bears reverse voltage significantly, make capacitor under bearing continuously and not breakdown greater than the situation of the reverse voltage of 3V, can under high ripple current, work thousands of hours and do not lose efficacy, improve useful life widely.
Description of drawings:
Accompanying drawing is a structural representation of the present invention.
In the accompanying drawing: anode tantalum piece 1 negative electrode tantalum tube 2 insulation underlays 3 electrolyte 4 pads 5 stick harnesses 6 O RunddichtringOs 7 tantalum shells 8 anode taps 9 cathode legs 10 tantalum wires 11 glass insulators 12 tantalum pipes 13 tantalum rings 14
Embodiment: the invention will be further described below in conjunction with accompanying drawing and specific embodiment:
In the accompanying drawings, at one end be welded with in the tantalum shell 8 of cathode leg 10 negative electrode tantalum tubes 2 be installed, this be by the punch forming of tantalum powder and behind sintering and form have a microporous tubular structure.One end is installed in the tube is with the anode tantalum piece 1 that insulation underlay 3, the other end fixedly are fitted with tantalum wire 11, this tantalum piece be by the punch forming of tantalum powder and behind sintering and form have a microporous column structure.Tantalum shell 8 is by stick harness 6 sealing of insulation, tantalum wire 11 from stick harness 6, pass and with anode tap 9 butt weldings.The outer surface of negative electrode tantalum tube 2 and the inner surface of tantalum shell 8 keep closely contact, and anode tantalum piece 1 separates by insulation underlay 3 and negative electrode tantalum tube 2 and forms certain clearance, filling electrolyte 4 in this gap.
In order to improve sealing, also be welded with glass insulator at the faucal place of tantalum shell 8.Described glass insulator is that the tantalum pipe 13 that by tantalum ring 14, fixedly is filled in glass insulator 12 wherein and is fixed on glass insulator 12 centre positions constitutes.The tantalum wire 11 that passes from stick harness 6 passes tantalum pipe 13 and anode tap 9 butt weldings and sealing.More reliable for the sealing that makes capacitor, in the outer ring of stick harness 6 an O RunddichtringO 7 can also be installed, and on tantalum shell 8, roll out the camber annular groove corresponding to sealing circle place.In order to adjust the position of stick harness 6, between stick harness 6 and anode tantalum piece 1, a pad 5 can also be installed.
