Description
Technical field
The utility model relates to capacitor design and manufacture field, is specifically related to non-solid electrolyte tantalum electrolytic capacitor negative electrode spot welding fixture (SWFX).
Background technology
Tradition non-solid tantalum electrolytic capacitor cathode leg adopts thermal-flame to burn the form of melting, the non-solid tantalum electrolytic capacitor of the new construction now studied, due to the difference of its structure, the spot welding of its cathode leg and the negative electrode spot-welding technology of traditional non-solid tantalum electrolytic capacitor are distinguished to some extent, the non-solid tantalum electrolytic capacitor cathode leg of new construction must adopt resistance melting welding, the cathode weld of tradition non-solid tantalum electrolytic capacitor can not meet the spot welding requirement of this new construction non-solid tantalum electrolytic capacitor cathode leg, thus the non-solid tantalum electrolytic capacitor for new construction is needed to design new weld jig, with cathode leg point is welded on the non-solid tantalum electrolytic capacitor of new construction rapidly and efficiently.
Utility model content
For solving the problems of the technologies described above, the utility model provides a kind of non-solid electrolyte tantalum electrolytic capacitor negative electrode spot welding fixture (SWFX), can be rapidly and efficiently welded on product by cathode leg point, and firm welding, meet and use.
The utility model is achieved by the following technical programs:
A kind of non-solid electrolyte tantalum electrolytic capacitor negative electrode spot welding fixture (SWFX), comprise base, top cover, electrode bar, air admission hole and through hole, the centre of base is provided with electrode bar, and the upper end of base is provided with top cover, air admission hole is arranged in top cover, has through hole in the middle of electrode bar.
Preferably, the upper surface of described base is provided with projection.
More preferably, described projection is annular protrusion, and top cover offers the groove matched with projection.
Preferably, the fastening bolt being arranged on base side is also comprised.
More preferably, electrode bar is fixed in the middle of base through base by described fastening bolt.
Preferably, described air admission hole flushes with the top of through hole.
Preferably, described electrode bar is the cylinder that conductive material is made.
Preferably, the diameter of described electrode bar and the equal diameters of top cover bottom.
The beneficial effects of the utility model are: solve the technical barrier that existing non-solid tantalum electrolytic capacitor cathode leg spot-welding technology does not meet new construction non-solid tantalum electrolytic capacitor cathode leg spot welding demand, and this cathode leg spot welding easy to operate, efficiency is high, welding effect good, can be used for go between the related experiment such as cripping test, pull test, torsion test.
