Abstract
The invention discloses a high-capacity electric double-layer capacitor cover plate assembly, which comprises a cover plate. The edge part of the cover plate is bent for two times to form a first side wall vertical to the cover plate and a second side wall extending outwardly and opposite to the direction of the first side wall. An insulation seat is arranged on the surface of a boss, the upper end of the insulation seat is provided with wiring terminals, the back face of the boss is provided with a sealing ring, a connection plate and a conductive sheet, and the conductive sheet, the connection plate, the sealing ring, the cover plate and the insulation seat are sequentially serially connected and positioned via rivets. The contact area with the capacitor is added through extending the height of the second side wall, the installation space of the connection plate is reduced through adding the boss, such that more gas generated inside the electric double-layer capacitor during the use process can be accommodated, the blasting time of an explosion-proof tank can be delayed, and the service life of the electric double-layer capacitor is prolonged.
Description
Technical field
The present invention relates to capacitor technology field, relate in particular to a kind of large capacity cover plate of super capacitor assembly.
Background technology
Ultracapacitor (Electric double-layer capacitor) is the electrochemical energy storage element between ordinary capacitor and chemical cell that development in recent years is got up; Because it has that power density is high, service life cycle is long and the advantage such as charging rate is fast, have broad application prospects at multiple fields such as mobile communication, electric tool, solar power generation, wind power generation, information technology and electric automobiles.
The especially large capacity ultracapacitor of ultracapacitor is in service in high pressure, large electric current impulse electricity work, particularly under high-temperature work environment, due to chemical reaction, electrochemical reaction and the high temperature evaporation of electric capacity inside, can make the inner gas that produces of ultracapacitor, the gas of these generations can be more and more under sealing state, the pressure that makes capacitor internal is gradually increasing, finally causes that the anti-explosion groove above capacitor case breaks, and capacitor damages and can not re-use.
Based on this reason, capacitor has much considerations for this problem in design, such as a certain amount of electrolyte of note, minimizing impurity and water content, is limited under certain voltage and uses etc.But these designs all cannot be dealt with problems at all, thereby, be necessary further to improve the structural design of capacitor, with further maximized prolongation its useful life.
Summary of the invention
In order to solve the technical problem existing in background technology, the present invention proposes a kind of large capacity cover plate of super capacitor assembly, prevent that the anti-explosion groove above capacitor case from breaking, so that capacitor damages and can not re-use.
The large capacity cover plate of super capacitor of the one assembly that the present invention proposes, comprise cover plate, be bent to form the first side wall vertical with cover plate for twice in the marginal portion of cover plate and stretch out and second sidewall reverse with the first side wall, the height of the second sidewall is greater than the height of the first side wall, be provided with in the center of cover plate and the first side wall boss in the same way, surface at boss is provided with insulating base, insulating base upper end is provided with binding post, the back side at boss is provided with sealing ring, connecting plate and conducting strip, conducting strip, connecting plate, sealing ring, cover plate and insulating base are connected in series location successively mutually by rivet.
Preferably, boss is truncated cone-shaped, and the height of boss is lower than the height of the first side wall.
Preferably, sealing ring and connecting plate are one-body molded.
Preferably, the projection that conducting strip is installed is set on connecting plate.
Preferably, projection periphery is provided with the catch of conducting strip enclosing.
Preferably, the thickness of cover plate is 0.25-0.35mm.
Large capacity cover plate of super capacitor assembly of the present invention, by extending, the height of the second sidewall increases and the contact area of capacitor, by increasing boss, reduce the installing space of connecting plate, to hold the inner gas producing of ultracapacitor in more use procedure, can delay the blasting time of anti-explosion groove, and then extend the useful life of super capacitor.
