Abstract
The utility model discloses an improved structure of a chip tantalum capacitor anode core block, belonging to the improvement of the chip tantalum capacitor anode core block. The utility model aims to provide a chip tantalum capacitor anode core block which is not easy to deform in the calcination process. The improved structure of the chip tantalum capacitor anode core block comprises an anode core block body and an anode leading-out line of which one end is embedded in the anode core block body. Tantalum foil (3) is embedded in the anode core block body (2). The deformation resistance of the anode core block body in the calcination process is effectively improved, and the deformation rejection rate in the calcination process is smaller than 5%. The chip tantalum capacitor anode core block is an anode core block used for making tantalum capacitors.
Description
Technical field
The utility model relates to a kind of chip tantalum capacitor anode pellet, relates in particular to a kind of chip tantalum capacitor anode pellet and improves structure.
Background technology
As everyone knows, anode pellet is the vitals of chip tantalum capacitor.At present, conventionally adopt the die cavity that tantalum powder is housed is put into in one end of anode lead wire, after compression molding, carry out again the mode of high-temperature calcination and make anode pellet.Due to the very thin thickness of anode pellet, easily distortion in calcination process, percent defective, up to 30～40%, can not meet the needs of large-scale production.
Summary of the invention
In order to overcome the defect existing in prior art, the utility model aims to provide on-deformable chip tantalum capacitor anode pellet in a kind of calcination process and improves structure.
To achieve these goals, the utility model by the following technical solutions: it comprises that anode pellet body, one end are embedded in the anode lead wire in this anode pellet body; In anode pellet body, be inlaid with tantalum paper tinsel.
Tantalum paper tinsel is I-shaped structure, and that section of anode lead wire and this tantalum paper tinsel that are embedded in anode pellet body are fixed.
Compared with the prior art, the utility model, owing to having adopted technique scheme, is inlayed an I shape tantalum paper tinsel that plays skeleton function in anode pellet body, has therefore effectively improved the non-deformability of anode pellet body in calcination process.Experiment showed, that anode pellet body after the improvement distortion percent defective in calcination process is less than 5%.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1.
In figure: anode lead wire 1, anode pellet body 2, tantalum paper tinsel 3.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail:
As shown in Fig. 1～2: be inlaid with tantalum paper tinsel 3 in anode pellet body 2, one end of anode lead wire 1 is embedded in anode pellet body 2 and is fixed with this tantalum paper tinsel.In order to reduce tantalum paper tinsel 3 consumptions, tantalum paper tinsel 3 is I-shaped structure.
While making anode pellet, tantalum paper tinsel 3 is put into the die cavity that place mat has tantalum powder, anode lead wire 1 is put into die cavity and overlap with tantalum paper tinsel 3, then evenly pour tantalum powder into, matched moulds is pressed into block structure.
Claims (2)
1. chip tantalum capacitor anode pellet improves a structure, comprises that anode pellet body, one end are embedded in the anode lead wire in this anode pellet body; It is characterized in that: in anode pellet body (2), be inlaid with tantalum paper tinsel (3).
2. chip tantalum capacitor anode pellet according to claim 1 improves structure, it is characterized in that: tantalum paper tinsel (3) is I-shaped structure, and that section of anode lead wire (1) being embedded in anode pellet body (2) is fixed with this tantalum paper tinsel.
