Abstract
The utility model discloses a lead-out riveted structure for an aluminum electrolysis capacitor, which is composed of a lead-out strip, a rivet column and a metal sheet. A rivet hole is arranged on the lead-out strip, one end of the rivet column runs through the rivet hole, and the other end is connected with a cover plate; a hole is arranged in the middle of the metal sheet; a side corner is arranged on the inside edge of the rivet hole when punching the rivet hole on the lead-out strip, the side corner can cling or wrap the rivet column wall, and the side corner and the rivet column wall can be nested in the inner side of the metal sheet. The riveting structure can enlarge the contact area of the lead-out strip and the rivet column, and reduce the contact resistance of the lead-out strip and the rivet column, the contact resistance thereof can be reduced by 30-50 percent by compared with the prior connecting method, and the connecting fastness of the lead-out strip and the rivet column can be strengthened.
Description
Technical field
The utility model relates to a kind of riveted structure of fuse and terminal of aluminium electrolytic capacitor, relates in particular to the riveted structure of a kind of cover-plate type capacitor core and cover plate terminal.
Background technology
For the cover-plate type aluminium electrolytic capacitor, mainly be to be connected with the fuse lead by the cover plate terminal to draw the product capacitance.At present on the connected mode between aluminium electrolytic capacitor lead and the cover plate terminal, most of producers adopt machinery to cold pressing, at first a circular port will be made a call on the lead, the rivet that will connect cover plate then passes the lead circular port, metal meson of overcoat on rivet again, by punching machine mold rivet is flattened, lead 1 and rivet are linked together, the product capacitance is drawn.In fact lead circular hole limit and rivet post are the line way of contact, the shortcoming of this connected mode is to produce big contact resistance at lead and rivet junction, flow through above-mentioned junction because of having during product work than large ripple current, produce big temperature rise and cause this junction because of thermal expansion distortion and temperature height, easily oxidation, produce the insulating properties oxide-film and cause lead to contact absent-mindedness with rivet, the product capacitance can not be drawn, make product failure.
Chinese patent CN2648576 discloses the syndeton of a kind of aluminium electrolytic capacitor slugs and terminal, be to be connected with spot welding between the inner of drawing paper tinsel and binding post of aluminium foil fuse, then its contact resistance approaches zero, so the loss tangent tg δ of capacitor is little, but this spot welding syndeton reliability is not high enough, be subjected to mechanicalness collision etc. easily and come off, especially for ultra-large volume, jumbo cover-plate type capacitor.
The utility model content
The technical problem that the utility model need solve provides the riveted structure of drawing of a kind of suitable ultra-large volume, cover-plate type aluminium electrolytic capacitor slugs and terminal.
The problem that the utility model need solve is achieved through the following technical solutions: a kind of aluminium electrolytic capacitor is drawn riveted structure, comprise on fuse lead, rivet post, metal Jie sheet, the lead rivet hole is arranged, rivet post one end passes rivet hole, the other end connects cover plate, porose in the middle of metal Jie sheet, the rivet hole inner side edge is along having the corner that forms when beating rivet hole on lead, corner to be close to or wrap up the rivet post jamb, metal Jie sheet socket corner, inboard and rivet post jamb.
Further: draw in the riveted structure at above-mentioned aluminium electrolytic capacitor, described corner is distributed in the front or the reverse side of lead.Described corner is petal-shaped or burr shape.Described rivet post is cylindrical, and corresponding rivet hole is circular; Perhaps described rivet post is a square column type, and corresponding rivet hole is square; Again or described rivet post be irregular cylindricality, corresponding rivet hole is irregular shape.Described metal Jie sheet is an aluminium flake.
In above-mentioned riveted structure, because when on lead, beating rivet hole, at the part lead at rivet hole place along cardiorrhexis in the hole, form the corner, this corner closely contacts with the rivet post, promptly contact with the line of rivet post jamb except rivet hole inner side edge edge, the corner that also has lead to extend closely contacts the rivet post jamb, increase the contact area of lead and rivet post, reduce the contact resistance of lead and rivet post, its contact resistance is compared with existing connected mode and has been reduced 30-50%, strengthens the fastness that lead is connected with the rivet post.The other end of rivet connects cover plate, thereby the capacity of fuse is drawn.
Description of drawings
Fig. 1 is the utility model perspective view; Fig. 2 is that enlarged diagram is overlooked by the utility model A portion.
Wherein 1 lead, 2 rivet holes, 3 cover plates, 4 metal Jie sheets, 5 rivet posts, 6 corners.
Specific embodiments
Following embodiment is the preferred scheme of the utility model, and the utility model is not the following embodiment of limitation, and those skilled in the art can be protection range of the present utility model according to the scheme that thinking of the present utility model filters out fully.
With reference to Fig. 1, Fig. 2: a kind of aluminium electrolytic capacitor is drawn riveted structure, comprise on fuse lead 1, rivet post 5, metal Jie sheet 4, the lead rivet hole 2 is arranged, rivet post 5 one ends pass rivet hole 2, the other end connects cover plate 3, porose in the middle of metal Jie sheet 4, rivet hole 2 inner side edges are along the corner 6 that forms when beating rivet hole 2 on lead 1 is arranged, corner 6 is close to or is wrapped up rivet post 5 post jambs, metal Jie sheet 4 inboard socket corners 6 and rivet post 5 post jambs, be that rivet post 5 post jambs are close in corner 6, and pass metal meson 4 together.Described corner 6 is distributed in the front or the reverse side of lead 1.Described corner 6 is petal-shaped or burr shape.Described rivet post 5 is cylindrical, and corresponding rivet hole 2 is circular; Perhaps described rivet post 5 is square column types, and corresponding rivet hole 2 is square; Again or described rivet post 5 are irregular cylindricalitys, corresponding rivet hole 2 is irregular shapes.Described metal meson sheet is an aluminium flake.The rivet post that will pass meson 4 by punching machine mold partly compresses then, and lead 1 is closely contacted with rivet post 5.
Except rivet hole 2 inner side edges edge contacts with the line of rivet post 5 post jambs, also have the corner 6 of the extension of lead 1 closely to contact rivet post 5 post jambs, increased the contact area of lead 1 with rivet post 5, reduce the contact resistance of lead 1 and 5 riveted joints place of rivet post, its contact resistance is compared with existing connected mode and has been reduced 30-50%, strengthens the fastness that lead 1 is connected with rivet post 5.Rivet post 5 other ends connect cover plate 3, thereby the capacity of fuse is drawn.
