Abstract
The present utility model discloses an anode leading-out part of a super capacitor. The part comprises an anode leading-out wire which is wrapped by a Kovar alloy sleeve and an insulator body with acid-filling holes, an installing hole is arranged on the insulator body, and the anode leading-out wire is arranged inside the installing hole and connected with the insulator body through an insulation layer. The part has the following beneficial effects, first, the anode leading-out wire is wrapped by the Kovar alloy sleeve, welding performance of an anode end is increased; second, as the weldability of the anode end is increased, when installing a capacitor, the anode end can be directly embedded into a panel and welded with a circuit, thus the capacitor body can be tightly clung to the circuit, the structure is simple, installing is convenient and firm; and third, as the capacitor is tightly combined with the circuit, stress endured by the capacitor anode end can be reduced when mechanical movement is realized, thus the anode end and the insulation layer of the sealing insulator can be protected, and the capacitor can work stably.
Description
Technical field
The utility model relates to a kind of anode leader part of ultracapacitor, relates in particular to a kind of sealing anode leader part with ultracapacitor of sealing property, belongs to electrolytic capacitor manufacturing technology field.
Background technology
Progress along with the tantalum electrolytic capacitor manufacturing technology, static capacity approaches or the tantalum capacitor that reaches the farad level becomes high-end member in the ultracapacitor, become preferred energy storage, filter element in the electric/electronic devices such as medical instrument, automotive electronics, laser equipment, wind energy, solar energy, it not only has the characteristics that volume is little, operating voltage is high, capacitance is large, leakage current is low, reliability is high, has also that high power density and the energy density of ultracapacitor, the speed that discharges and recharges are fast, lead and cadmium free heavy metal pollution, long-life advantage.
At present, the structure of super tantalum capacitor is by advancing in the metal shell with the common encapsulation of electrolyte behind a plurality of anode tantalum pieces, cathode sheets, the insulating spacer juxtaposition, the lead-out wire of a plurality of anode tantalum pieces is welded on the tantalum rod of sealing insulator jointly, fill between tantalum rod and sealing insulator body with glass or ceramic as insulating barrier, be welded with negative outside wire on the sealing insulator body, the exit of cathode sheets and sealing insulator, shell are welded together, finish the sealing of capacitor.
Yet, current practice be with the wire bonds of anode block in tantalum rod bottom, the tantalum rod is directly as the anode exit.Because the welding performance of tantalum rod is relatively poor, when installing, super tantalum capacitor welds nickel wire on tantalum rod top, realize being electrically connected by nickel wire and circuit again.Such installation method namely uses fluid sealant fixed capacitor body, capacitor is contacted with the circuit printing plate gapless, the mechanical stability variation that causes complete machine, the ease of connection when test or operation between capacitor and circuit disconnects, and uses extremely inconvenience.
Summary of the invention
The purpose of this utility model is to provide a kind of anode leader part of ultracapacitor simple in structure, easy for installation, can improve the welding performance of anode tap, and capacitor is combined closely with circuit, makes the capacitor can steady operation.
The purpose of this utility model is achieved through the following technical solutions: a kind of anode leader part of ultracapacitor, it comprises that but outer wrap has the positive outside wire of valve alloy overcoat and with the insulator body in acid filling hole, be provided with installing hole on the insulator body, positive outside wire is installed in the installing hole and by insulating barrier and is connected with insulator body.
Described insulating barrier is the sintered body of glass dust or ceramic powder.
Described insulator body is bowl structure.
The beneficial effects of the utility model are: (1) but the outside valve alloy overcoat that coats of positive outside wire has strengthened the welding performance of anode tap; (2) because the solderability of anode tap strengthens, and capacitor can directly embed panel with anode tap when installing, and anode tap and circuit are welded together, thereby capacitor body can be close to circuit, and is simple in structure, easy for installation and firm; (3) because capacitor is combined with circuit closely, when mechanical movement, the suffered stress of capacitor anode end is alleviated, thereby has protected the insulating barrier on anode tap and the sealing insulator, so that capacitor can steady operation.

Fig. 2 is vertical view of the present utility model.
Wherein, 1-insulator body, 2-insulating barrier, but 3-valve alloy overcoat, 4-positive outside wire, 5-acid filling hole, 6-installing hole.
Embodiment
Further describe the technical solution of the utility model below in conjunction with accompanying drawing, but that claimed scope is not limited to is described.
Such as Fig. 1, Fig. 2, a kind of anode leader part of ultracapacitor, it comprises that but outer wrap has the positive outside wire 4 of valve alloy overcoat 3 and with the insulator body 1 in acid filling hole 5, be provided with installing hole 6 on the insulator body 1, positive outside wire 4 is installed in the installing hole 6 and by insulating barrier 2 and is connected with insulator body 1.
Described insulating barrier 2 is the sintered body of glass dust or ceramic powder, after positive outside wire 4 is installed in insulator body 1, in insulator body 1 and 4 fillings of positive outside wire with glass dust or ceramic powder, put into Muffle furnace after glass dust or the compacting of ceramic powder compression and calcine, until glass dust or ceramic powder melting namely form the insulating barrier 2 of connecting insulator body 1 and positive outside wire 4.
Described insulator body 1 is bowl structure.
When carrying out super tantalum capacitor assembling, the lead-out wire of anode tantalum piece is welded on the positive outside wire 4 simultaneously, stack successively insulating spacer and cathode sheets on anode tantalum piece surface, consist of the capacitor core sub-component, core assembly is put into shell, with shell, cathode sheets, insulator body 1 seal welding together, inject electrolyte by acid filling hole 5 at last.
