Abstract
The utility model discloses an aluminum electrolytic capacitor, including the lead wire, the apron is provided with the riveting hole on the lead wire, the lead wire with the apron links to each other its characterized in that through the rivet that penetrates the rivet hole: and a flange is arranged on the riveting hole. The utility model discloses increased the contact surface of lead wire and rivet, effectively reduced contact resistance between lead wire and the apron, reduced condenser electrical parameter loss value, its contact resistance falls to 0.02m omega-0.06 m omega, and condenser electrical parameter loss value descends about 1.8%.
Description
Technical field
The utility model relates to a kind of aluminium electrolytic capacitor.
Background technology
At present, the core bag of big capacity aluminium electrolytic capacitor lead-in wire mainly adopts the riveted joint mode with cover plate, and the quality of riveting quality directly affects the many technical indicator parameters of aluminium electrolytic capacitor.Its riveted joint adopts punch press in the punching of lead-in wire head, and lead-in wire passes punching and cover plate rivet riveted way.Punching and cover plate rivet circumference have certain interval owing to go between, and lead-in wire is very little with the rivet contact-making surface, and when the main back cushion plate plane of electric current, cover plate end face passed through with the lead-in wire flat contact surface, contact resistance was bigger than normal, generally in 0.04m Ω-0.09m Ω scope.So direct phenomenon causes the electrical quantity loss big exactly.Long-time during by big electric current between terminal in the use, the heating oxidation of riveted joint contact site can cause capacitor to lose efficacy when contact resistance continues to increase.
Summary of the invention
Technical problem: in order to overcome above-mentioned defective, the utility model provides a kind of aluminium electrolytic capacitor that reduces contact resistance.
Technical scheme: the technical scheme in the invention for solving the technical problem is: a kind of aluminium electrolytic capacitor, comprise lead-in wire, cover plate, lead-in wire is provided with riveted holes, described lead-in wire links to each other by the rivet that penetrates rivet hole with described cover plate, it is characterized in that: described riveted holes is provided with flange.
Beneficial effect: the utility model is by being provided with flange on rivet hole, increased the contact-making surface with rivet, effectively reduces the resistance of getting an electric shock indirectly of lead-in wire and cover plate, thereby reduced capacitor electrode parameters-loss value.Its contact resistance can be reduced to 0.02m Ω-0.06m Ω, and capacitor electrode parameters-loss value descends about 1.8%, the useful life that can improve capacitor.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples
Fig. 1 is the utility model structural representation.
Fig. 2 is the schematic diagram of pin configuration in the utility model.
Among the figure 1, lead-in wire, 2, cover plate, 3, rivet, 4, rivet hole, 5, flange
Embodiment
With lead-in wire was gone up and cover plate links by rivet in the past rivet hole be form by mould punching different, in the present embodiment, the rivet hole that connects lead-in wire and cover plate cuts lead-in wire with the rhombus mould and forms, the rivet hole core disconnects, can pass rivet, do not remove lead material during incision, it is the magic flower shape keeps, thereby increase contact-making surface with rivet, effectively reduce lead-in wire and the cover plate resistance of getting an electric shock indirectly, reduced capacitor electrode parameters-loss value, its contact resistance is reduced to 0.02m Ω-0.06m Ω, and capacitor electrode parameters-loss value descends about 1.8%.
