Abstract
A super capacitor with a sealing ring belongs to the technical field of super capacitors and is fine in sealing property and high in reliability. The super capacitor comprises a capacitor shell, a coiled core is disposed in the capacitor shell, a terminal cover plate is arranged on the coiled core, and an insulation ring is disposed between the upper edge of the terminal cover plate and the capacitor shell. The super capacitor is characterized in that the terminal cover plate is provided with a clamp groove, the sealing ring is arranged in the clamp groove of the terminal cover plate and corresponds to a waist band of the capacitor shell, and the width of the sealing ring corresponds to that of the clamp groove.
Description
Technical field:
The utility model belongs to the ultracapacitor technical field, particularly relates to a kind of ultracapacitor with sealing ring.
Background technology:
Ultracapacitor is a kind of novel energy-storing device, has good high-power charge-discharge performance, energy conversion efficiency height, good temp characteristic, recycles advantages such as life-span length, environmental protection; Thereby its technology has been subjected to the generally attention of countries in the world.Taken into account battery and traditional capacitor characteristics separately because of it, had good performance, and be widely used in the various industrial products that have power storage and a high power discharge.
The sealing quality of ultracapacitor is very big to the performance impact of ultracapacitor, if seal badly, can cause the ultracapacitor electrolyte inside directly to contact with extraneous air, makes the rotten and salinization of electrolyte; Make the conductivity of electrolyte seriously descend, cause the ultracapacitor internal resistance to increase gradually, finally make product failure.And, be easy to make electrolyte to leak if the ultracapacitor sealing is bad, cause the inefficacy of ultracapacitor, cause the unnecessary loss such as corrosion of exterior part and circuit board simultaneously.
The utility model content:
At the bad problem of existing ultracapacitor sealing, the utility model provides a kind of good airproof performance, the ultracapacitor with sealing ring that reliability is high.
To achieve these goals, the utility model adopts following technical scheme, a kind of ultracapacitor with sealing ring, comprise capacitor case, be provided with the volume core in the inside of capacitor case, above the volume core, be provided with the terminal cover plate, between the upper edge of terminal cover plate and capacitor case, be provided with insulated ring; Be characterized in that described terminal cover plate has draw-in groove, be provided with sealing ring in the draw-in groove of terminal cover plate, described sealing ring is with a tight waist corresponding with capacitor case, and the width of sealing ring is corresponding with draw-in groove.
Described sealing ring is that cross section is the O-ring seal of rectangle.
The thickness of described sealing ring is 5～10mm.
The beneficial effects of the utility model:
Because terminal cover plate of the present utility model has draw-in groove, is provided with sealing ring in the draw-in groove of terminal cover plate, described sealing ring is with a tight waist corresponding with capacitor case; Just make ultracapacitor good airproof performance of the present utility model, reliability height.
In addition, ultracapacitor of the present utility model also has a series of advantages such as manufacture craft is simple, with low cost.
Description of drawings:
Fig. 1 is the structural representation of ultracapacitor of the present utility model;
Fig. 2 is the sectional view of sealing ring of the present utility model;
Fig. 3 is the sectional view of terminal cover plate of the present utility model;
Among the figure, 1-rolls up core, the 2-capacitor case, and 3-terminal cover plate, the 4-sealing ring, 5-is with a tight waist, 6-insulated ring, 7-draw-in groove.
Embodiment:
As Fig. 1, shown in Figure 3, a kind of ultracapacitor with sealing ring comprises capacitor case 2, is provided with volume core 1 in the inside of capacitor case 2, above volume core 1, be provided with terminal cover plate 3, between the upper edge of terminal cover plate 3 and capacitor case 2, be provided with insulated ring 6; Described terminal cover plate 3 has draw-in groove 7, is provided with sealing ring 4 in the draw-in groove 7 of terminal cover plate 3, described sealing ring 4 and capacitor case 2 with a tight waist 5 corresponding, and the width of sealing ring is corresponding with draw-in groove, is typically designed to 5～10mm.
As shown in Figure 2, described sealing ring 4 is the O-ring seal of rectangle for cross section.The thickness of described sealing ring 4 is 5～10mm.
Described sealing ring 4 adopts resistant materials such as butyl rubber or polytetrafluoroethylene to make.
When processing ultracapacitor of the present utility model, at first, with cross section is that O-ring seal 4 integral body of rectangle are enclosed within the draw-in groove 7 of terminal cover plate 3, the electrode of terminal cover plate 3 with volume core 1 is connected, terminal cover plate 3 and volume core 1 are packed in the capacitor case 2, and with capacitor case 2 with the volume core 1 another electrode be connected, at this moment, sealing ring 4 is between capacitor case 2 and terminal cover plate 3; Then, with a tight waist to capacitor case 2 by rotating sealing machine with a tight waist in sealing ring 4 positions, thus make sealing ring 4 compressive deformations realize positiver sealing.The degree of depth with a tight waist is to make sealing ring 4 be deformed into 1/2～2/3 of original thickness, reaches the sealing to product.
