Description
【Technical field】
The utility model is related to solid electrolytic capacitor production technical field, more particularly to a kind of polymer of high moisture-proof
Chip-type laminated solid aluminum electrolytic capacitor.
【Background technology】
Compared to liquid alminium electrolytic condenser, the chip-type laminated solid aluminum electrolytic capacitor of polymer is more suitable for surface mount,
Also it is more stable under the conditions of applied at elevated temperature, but due to being influenced be subject to packaging air tightness, the ability of resistance to high humility is not dashed forward
Go out, the performance of this aspect also limits the application range and development prospect of chip-type laminated alminium electrolytic condenser bigger.
【Utility model content】
The purpose of this utility model is to provide a kind of chip-type laminated solid aluminum electrolytic capacitor of polymer of high moisture-proof,
Waterproof coating is prepared by the cathode in dissimilar core, prevents steam from entering inside fuse, improves the moisture-proof ability of capacitor.
The utility model solves above-mentioned technical problem using following technical scheme.
A kind of polymer chip-type laminated solid aluminum electrolytic capacitor of high moisture-proof, if including lead terminal, plastic packaging material and
Dry lamination fuse, the lamination fuse include aluminium, aluminum oxide dielectric layer, conductive solid polymer dielectric successively from inside to outside
Layer, carbon containing cathode layer and silver-contained cathode layer；It is characterized in that the silver-contained cathode layer bottom is equipped with cathode waterproof layer, the cathode
Waterproof layer height is no more than the 20% of the silver-contained cathode layer.
Further, the cathode waterproofing layer thickness scope is 1 μm -50 μm.
Further, the cathode waterproof layer material is polyurethane, polyacrylate, polyvinyl acetate, polyethylene third
One kind or its mixture in synthetic fibre, silicon rubber.
The utility model has the advantage of by the cathodic region of polymer chip laminated aluminum electrolytic capacitor cartridge units
Bottom covers one layer of hydrophobic material so that the solid aluminum electrolytic capacitor of preparation has better moisture resistance properties.
【Description of the drawings】
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Fig. 1 is the organigram of the utility model embodiment.
Reference numeral is as follows：
1st, aluminium；2nd, aluminum oxide dielectric layer；3rd, conductive solid polymer electrolyte layer；4th, carbon containing cathode layer；5th, argentiferous is cloudy
Pole layer；6th, lead terminal；7th, electrically conducting adhesive；8th, glue is obstructed；9th, plastic packaging material；10th, cathode waterproof layer.
【Specific embodiment】
The chip-type laminated solid aluminum electrolytic capacitor of polymer of the utility model is illustrated according to Fig. 1, including aluminium 1, oxygen
Change Al-electrolyte layer 2, conductive solid polymer electrolyte layer 3, carbon containing cathode layer 4, silver-contained cathode layer 5, the fuse for obstructing glue 8,
Bottom is immersed in in hydrophobic polyurethane mixed liquor, forms cathode bottom waterproof layer 10, then polymer is chip-type laminated
The cathode of solid aluminum electrolytic capacitor fuse is adhered to the cathode terminal of lead terminal 6 by conductive adhesive 7, and anode passes through welding
The stacking completed on the anode tap of lead terminal 6 with lead terminal is adhered to, it is whole that plastic packaging is carried out with plastic packaging material 9 again.
The utility model can reduce steam to fuse by being protected in core cathode bottom using hydrophobic material
It corrodes, so as to promote the moisture-proof ability of product.The utility model material is rationally easy to get, preparation process is simple, is suitble to push away on a large scale
Wide application.
The above are the preferred embodiment of the utility model, all changes made according to technical solutions of the utility model are produced
Function without departing from technical solutions of the utility model scope when, belong to the scope of protection of the utility model.
