Abstract
The utility model discloses an anti-creeping tantalum capacitor, comprising a tantalum housing with one end provided with an opening and an inner wall plated with a ruthenium dioxide layer, a cathode leading-out wire fixed to the bottom of the tantalum housing, an anode tantalum block fixed in the tantalum housing through a fixing washer, a top cover covering the opening of the tantalum housing and an anode leading-out wire fixed in the anode tantalum block after traversing the center of the top cover, wherein the outer wall of the anode tantalum block is wrapped by a layer of polyimide diaphragm. The anode tantalum block in the tantalum capacitor is wrapped by the polyimide diaphragm, which blocks contact between a chip and a ruthenium oxide electrode, avoids short circuit problems caused by the contact between a chip and a cathode caused by various reasons and electric leakage problems and substantially increases the service life of the tantalum capacitor.
Description
Technical field
The utility model belongs to electrolytic capacitor manufacturing technology field, is specifically related to a kind of anticreep tantalum capacitor.
Background technology
The core of high energy tantalum capacitor is electrode active material ruthenic oxide and anode tantalum piece, the ruthenic oxide powder comes off when being subjected to the mechanical shock of outside higher magnitude, dither, random vibration easily, and the powder that comes off will stick on the tantalum capacitor anode tantalum piece, finally causes leaky condenser because electrode material migrates to anode tantalum piece.
The utility model content
The purpose of this utility model is: a kind of anticreep tantalum capacitor is provided, stick on the anode tantalum piece because mechanical shock, dither, random vibration cause its inner ruthenic oxide powder to come off to solve existing tantalum capacitor, cause the problem of leaky condenser.
The purpose of this utility model is achieved by following technical solution:
A kind of anticreep tantalum capacitor, the top cover that comprise tantalum shell that an end is provided with opening and inwall and is coated with the ruthenic oxide layer, be fixed in the negative outside wire of tantalum outer casing bottom, the anode tantalum piece in retaining washer is fixed on described tantalum shell, lid is contained in tantalum shell aperture place, be fixed in the positive outside wire of anode tantalum piece inside after passing the top cover center, wherein: described anode tantalum piece outer wall is enclosed with one deck polyimide diaphragm.
Preferably, described retaining washer is polytetrafluoroethylene gasket.
Compared with prior art, the anticreep tantalum capacitor that the utility model provides is wrapped by polyimide diaphragm owing to its anode tantalum piece, having prevented that the ruthenic oxide powder is subjected to come off behind the mechanical tests such as mechanical shock, dither, random vibration contacts with the direct of fuse, avoid the problem of leaky condenser, effectively promoted the useful life of capacitor.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation behind the anode tantalum piece parcel barrier film in the utility model;
Among the figure: 1-positive outside wire, 2-top cover, 3-ruthenic oxide layer, 4-anode tantalum piece, 5-tantalum shell, 6-negative outside wire, 7-retaining washer, 8-polyimide diaphragm.
Embodiment
Below in conjunction with accompanying drawing the technical solution of the utility model is described further, but that desired protection range is not limited to is described:
As shown in Figure 1, 2, the anticreep tantalum capacitor that the utility model provides, the top cover 2 that comprise tantalum shell 5 that an end is provided with opening and inwall and is coated with ruthenic oxide layer 3, be fixed in the negative outside wire 6 of tantalum shell 5 bottoms, the anode tantalum piece 4 in retaining washer 7 is fixed on described tantalum shell 5, lid is contained in tantalum shell 5 opening parts, pass the positive outside wire 1 that is fixed in anode tantalum piece 4 inside behind top cover 2 centers, wherein: described anode tantalum piece 4 outer walls are enclosed with one deck polyimide diaphragm 8.
For further promoting useful life of the present utility model, described retaining washer 7 adopts polytetrafluoroethylene gasket.
The anticreep tantalum capacitor that the utility model provides, its inner anode tantalum piece 4 surfaces are wrapped up by polyimide diaphragm 8, blocked contacting of fuse and ruthenium-oxide electrode, block the fuse that causes because of a variety of causes and contacted the short circuit problem that causes with negative electrode, avoided the appearance of electric leakage problem, big leap ahead useful life of tantalum capacitor.
