Description
Technical field
The utility model relates to a kind of closing device of ultracapacitor.
Background technology
It is a kind of Novel energy storage apparatus that ultracapacitor is again double electric layer capacitor, and it has the features such as short, long service life of charging interval, good temp characteristic, energy savings and environmental protection.Capacitor need to seal and prevent electrolyte leakage, needs again to prevent that electrolyte is overheated, can cause the explosion of capacitor when pressure is excessive.Sealing means great majority between shell and the hush panel of traditional ultracapacitor adopt the form sealing of flexible rubber ring, and cushion rubber exposes, and such sealing means is because capacitor generates heat, and its inner electrolyte is easily revealed, and useful life is short; For the pressure relief device of capacitor, great majority are all by engrave thinner indent trace on shell, in the time that container internal pressure is too high, impression will break to reach the object of release, and such mode difficulty of processing is larger, because shell is generally thicker, to be difficult to for the control of impression thickness, to reach sealed explosion-proof effect and also have for electric capacity by welded seam, not only to seal but also explosion-proof effect in order reaching, its butt welded seam to melt dark requirement strict, implement also more difficult.
Utility model content
The purpose of this utility model is to provide a kind of closing device of ultracapacitor, to overcome currently available technology above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of closing device of ultracapacitor, comprise shell, hush panel and liquid injection hole, between described shell and described hush panel, adopt the form sealing of welding, in the middle of described hush panel, offer centre bore, in described centre bore, be provided with pole, described liquid injection hole is opened in hush panel, in described liquid injection hole, be provided with the explosion-proof seal nail matching with it, the ailhead of described explosion-proof seal nail is truncated cone-shaped, the procephalic diameter of described nail is greater than the diameter at described ailhead rear portion, and the end of described ailhead offers chamfering.
Further, described liquid injection hole be shaped as step-like.
Further, described pole is provided with screw thread, is from left to right provided with successively nut, copper aluminium meets pad, binding nut, boss shape pad and annular gasket on described pole, and the screw thread of described binding nut and the screw thread of nut are all suitable with the screw thread of pole; The projection section of described boss shape pad is closely set on pole through described centre bore, and described annular gasket is closely set in the inner side of hush panel, and described boss shape pad and described annular gasket are interlocked.
Further, the end of described pole is provided with cylinder boss, and on described cylinder boss, clamping is provided with collector plate.
Preferably, the weld seam welding manner between described shell and hush panel is Laser Welding.
The beneficial effects of the utility model are: simple in structure, process simple and easy, adopt welding form sealed capacitor, sealing effect is good, makes the long service life of product, the design of explosion-proof seal nail, both play the effect of sealing, effectively reached again the effect of safety anti-explosive.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the closing device structural representation of the ultracapacitor described in the utility model embodiment;
Fig. 2 is the structural representation of the hush panel described in the utility model embodiment.
In figure:
1, shell; 2, hush panel; 3, liquid injection hole; 4, explosion-proof seal nail; 5, centre bore; 6, pole; 7, boss shape pad; 8, annular gasket; 9, binding nut; 10, copper aluminium meets pad; 11, nut; 12, cylinder boss; 13, collector plate.
Embodiment
As shown in Figure 1-2, the closing device of a kind of ultracapacitor described in the utility model embodiment, a kind of closing device of ultracapacitor, comprise shell 1, hush panel 2 and liquid injection hole 3, between described shell 1 and described hush panel 2, adopt the form sealing of welding, in the middle of described hush panel 2, offer centre bore 5, in described centre bore 5, be provided with pole 6; Described liquid injection hole 3 is opened in hush panel 2, in described liquid injection hole 3, be provided with the explosion-proof seal nail 4 matching with it, the ailhead of described explosion-proof seal nail 4 is truncated cone-shaped, and the procephalic diameter of described nail is greater than the diameter at described ailhead rear portion, and the end of described ailhead offers chamfering; Described pole 6 is provided with screw thread, on described pole 6, be from left to right provided with successively nut 11, copper aluminium meets pad 10, binding nut 9, boss shape pad 7 and annular gasket 8, the screw thread of the screw thread of described binding nut 9 and nut 11 is all suitable with the screw thread of pole 6; The projection section of described boss shape pad 7 is closely set on pole 6 through described centre bore 5, and described annular gasket 8 is closely set in the inner side of hush panel 2, and described boss shape pad 7 is interlocked with described annular gasket 8; The end of described pole 6 is provided with cylinder boss 12, and on described cylinder boss 12, clamping is provided with collector plate 13; Weld seam welding manner between described shell 1 and hush panel 2 is Laser Welding.
When concrete use, because between shell 1 and hush panel 2 being adopts the form of welding to seal, save traditional mode with rubber sealing, sealing effectiveness is better, traditional cushion rubber form sealing, cushion rubber very easily damages, cause poorly sealed, useful life is not long, the good sealing effect of weld seam, not easy-to-leak liquid, when electrolyte is during in capacitor case 1 internal heat generation, just easily make container inner pressure increase, now, after in container, fluid injection completes, do not adopt traditional form sheet metal that liquid injection hole 3 is sealed, but utilize explosive-proof sealed nail 4 that has a tapering to enter liquid injection hole 3 from outside ground nail, the head of a nail of explosive-proof sealed nail 4 clamps the countersunk head end of step-like liquid injection hole 3, sealing effectiveness is also relatively good, in the time that container inner pressure increases, also just because explosion-proof seal nail 4 is by tapering, so electrolyte will be extruded explosion-proof seal nail 4 with comparalive ease, realize the object of safe unloading pressure.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection range of the present utility model.
