Description
Technical field
It the utility model is related to a kind of electronic component, and in particular to a kind of aluminium electrolutic capacitor.
Background technology
At present, the development trend of aluminium electrolutic capacitor is to high pressure, Large Copacity and miniaturization.It is compact for internal structure
Capacitor for, easily because cover plate and core Inter-packet gap it is small extrude lead-out wire, cause lead-out wire deform or fracture, made after extruding
Into short circuit between positive and negative lead-out wire.
The core bag lead of Large Copacity aluminium electrolutic capacitor mainly uses riveting method with cover plate, and the quality of riveting quality is directly
Affect many technical indicator parameters of aluminium electrolutic capacitor.It is riveted using punch press in the punching of lead head, is then enclosed on cover plate
Shell tool is riveted on rivet.Due to having certain interval, lead and rivet contact surface around lead punching and cover plate rivet
Very little, electric current mainly by pad plane, cover plate end face and lead flat contact surface by when, contact resistance is bigger than normal, so direct
Cause electrical parameter loss big.When terminal passes through high current for a long time in use, the heating oxidation of riveting contact site, work as contact resistance
Continue that during increase capacitor failure can be caused.
Utility model content
The utility model makes improvement for the above-mentioned problems of the prior art, i.e., skill to be solved in the utility model
Art problem is to provide a kind of aluminium electrolutic capacitor, and manufacturing process is simple, effectively reduces contact resistance, while saves material cost,
For enterprise's cost efficiency.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：
A kind of aluminium electrolutic capacitor, including housing and cover plate, anode foils, Cathode Foil and electrolysis are provided with the housing
Paper, the electrolytic paper, which is interposed between anode foils and Cathode Foil, is wound into cylindric core bag, and the cover plate lid is located at the core bag top
Portion and it is hermetically connected with the shell, has capillary by rivet on the cover plate, two groups of lead-out wires are provided with below the cover plate,
Two groups of lead-out wire one end are riveted with anode foils, Cathode Foil respectively, and the other end is welded with cover plate rivet bottom using laser spot welding respectively
It is connected together.
Preferably, the housing is aluminum hull.
Preferably, the aluminum hull inwall is provided with one layer of erosion resisting insulation film.
Preferably, the periphery of the aluminum hull is coated with insulation rubber tube.
Preferably, the insulation rubber tube is made up of material contracting with heat.
Compared with prior art, the utility model aluminium electrolutic capacitor is connected with lead-out wire by cover plate and uses laser spot welding
The mode advantage of connection is：（1）Contact resistance is effectively reduced, avoids product initial failure caused by loose contact or open circuit
Phenomena such as；（2）Lead-out wire shortens technological process, greatly improves production efficiency without punching；（3）Rivet is without pass through extraction
Line is added gasket, and is shortened the length of rivet, is enterprise's cost efficiency so as to save material；（4）Rivet is with drawing linear contact lay thickness
Reduce, the gap of increase cover plate and core bag, avoid lead-out wire crimp or fracture from causing short circuit between positive and negative lead-out wire.

Fig. 2 is lead-out wire and the partial enlarged drawing of backboard attachment structure；
Fig. 3 is lead-out wire and the upward view of backboard attachment structure.
In figure：1- housings, 2- core bags, 3- lead-out wires, 4- rivets, 5- capillaries, 6- cover plates, 7- laser solder joints.
Embodiment
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
As shown in figure 1, a kind of aluminium electrolutic capacitor, including housing 1 and cover plate 6, be provided with the housing 1 anode foils,
Cathode Foil and electrolytic paper, the electrolytic paper, which is interposed between anode foils and Cathode Foil, is wound into cylindric core bag 2, and the cover plate 6 covers
It is located at the top of core bag 2 and is tightly connected with housing 1, has capillary 5, the cover plate 6 by the riveting of rivet 4 on the cover plate 6
Lower section is provided with two groups of lead-out wires 3, and two groups of one end of lead-out wire 3 rivet with anode foils, Cathode Foil respectively, the other end respectively with cover plate
The bottom of 6 rivet 4 is welded together using laser spot welding.
Preferably, the housing 1 is aluminum hull, and aluminum hull inwall is provided with one layer of erosion resisting insulation film, and the periphery of aluminum hull is coated with
Insulation rubber tube, the insulation rubber tube are made up of material contracting with heat.
The utility model aluminium electrolutic capacitor is excellent by way of cover plate 6 is connected using laser spot welding connection with lead-out wire 3
Point is：（（1）Contact resistance is effectively reduced, caused by avoiding loose contact or open circuit phenomena such as product initial failure；（2）
Lead-out wire 3 shortens technological process, greatly improves production efficiency without punching；（3）Rivet 4 is without pass through the cushioning of lead-out wire 3
Piece, the length of rivet 4 is shortened, be enterprise's cost efficiency so as to save material；（4）Rivet 4 contacts thickness with lead-out wire 3 and subtracted
It is few, the gap of increase cover plate 6 and core bag 2, avoid the crimp of lead-out wire 3 or fracture from causing short circuit between positive and negative lead-out wire 3.
The foregoing is only preferred embodiment of the present utility model, it is all done according to present utility model application the scope of the claims it is equal
Deng change and modification, it should all belong to covering scope of the present utility model.
