Description

A kind of shell of high capacity cell

Technical field

The utility model relates to a kind of battery, more particularly, relates to a kind of structure of high capacity cell shell.

Background technology

The shell of NI-G, ni-mh two inferior batteries has certain requirement of withstand voltage.At present, the conventional capacity of NI-G, nickel-hydrogen secondary cell is less than 15Ah, and the resistance to compression of shell requires lower, and edge sealing is simpler, in general, adopts traditional punch press pier encapsulation technique just can satisfy and wants.Though the traditional pier encapsulation technique has the simple advantage of technology.But the edge sealing of this battery case is not suitable for NI-G, the nickel-hydrogen secondary cell of capacity greater than 15Ah.

Summary of the invention

At the deficiencies in the prior art, the purpose of this utility model provides a kind of shell of high capacity cell, and it has in conjunction with firm sealing end and seal closure, is fit to NI-G, the nickel-hydrogen secondary cell use of capacity greater than 20Ah.

The purpose of this utility model is achieved in that a kind of shell of high capacity cell, comprises shell, and shell is cylindrical, shell has sealing end, and sealing end has seal closure, and sealing end has convex tendon, fluted on the seal closure, the groove on the corresponding seal closure of the convex tendon on the sealing end.

On the basis of technique scheme, the utility model also has following further scheme:

Described sealing end has flange.

On the described seal closure flange is arranged.

There is the depression position at described envelope flange middle part, and depression has Raschig ring in the position.

There are sealing end and seal closure in described shell two ends.

Described shell is a stainless steel tube.

Described housing diameter is greater than 35 millimeters.

Advantage of the present utility model is as follows:

Because shell has sealing end, sealing end has seal closure, sealing end has convex tendon, fluted on the seal closure, groove on the corresponding seal closure of convex tendon on the sealing end, convex tendon on the sealing end embeds the groove on the seal closure, and seal closure not only can be securely in conjunction with shell, and has created condition for further fastening seal closure.Such as, under the support of seal closure, can use the clamp clamps shell, on sealing end, process combining of the further stiffened shell of flange and seal closure.The utility model is applicable to the high capacity cell of diameter more than 35 millimeters, and the capacity that is particularly suitable for is greater than 15Ah NI-G, Ni-MH battery.

Embodiment

Below in conjunction with accompanying drawing in detail execution mode of the present utility model is described in detail:

Referring to Fig. 1.A kind of shell of high capacity cell, shell 2 is made cylindrical, and shell 2 diameters are greater than 35 millimeters, and shell 2 diameters can be 40 millimeters or 100 millimeters, and shell 2 height can be at 60 millimeters or 160 millimeters.Be noted that the diameter of shell 2 and highly can also be the size of other standard cell.Described shell 2 is a stainless steel tube, and shell 2 can adopt the manufacturing of thin-wall seamless stainless steel tube, and in general, the stainless steel tube wall thickness can be decided according to shell 2 diameters, and during 60 millimeters of shell 2 diameters, the wall thickness of stainless steel tube can be 1 millimeter or 0.8 millimeter.Shell 2 has sealing end 4, and sealing end 4 is the open positions at shell 2 two ends, and when shell 2 adopted drawing process to make, shell 2 can only at one end leave sealing end 4.As, shell 2 uses the corrosion resistant plate manufacturing of 0.4 millimeter thickness, and drawn, punching press can form the round-ended cylinder that has of cup shape.Can put into the electric core of battery by sealing end 4, electric core is after sealing end 4 is put into shell 2, again with seal closure 1 encapsulation.Seal closure 1 on the sealing end 4 can use the metal material manufacturing, seal closure 1 is provided with the insulating regions and the electrode of installing electrodes, also safety exhaust can be set on the seal closure 1, when seal closure 1 was all used in shell 2 two ends, safety exhaust can be arranged on the seal closure 1 of shell 2 bottoms.

Sealing end 4 has convex tendon 6, convex tendon 6 on the sealing end 4 can be realized by processing modes such as roll extrusion or extruding, convex tendon 6 can be provided with 2 roads or 3 roads, roll extrusion or extruding are during convex tendon 6 on sealing end 4, seal closure 1 places earlier in the sealing end 4, and the groove 3 on the seal closure 1 is prefabricated, and shell 2 is behind processing modes such as roll extrusion or extruding, convex tendon 6 on the sealing end 4 can embed the groove 3 on the seal closure 1, i.e. groove 3 on the 6 corresponding seal closures 1 of convex tendon on the sealing end 4.Can add encapsulants such as fluid sealant or rubber between the groove 3 on convex tendon 6 and the seal closure 1.In order further to strengthen being connected of sealing end 4 and seal closure 1, the utility model can also be taked following further step:

Described sealing end 4 has flange 5.The size of flange 5 can be decided according to shell 2 diameters or processing request.In conjunction with Fig. 1 referring to Fig. 3.Flange 5 width shown in Figure 1 are smaller, and flange 5 is just rolled a limit at sealing end 4, but 5 pairs of seal closures 1 of flange have certain barrier effect.The flange 5 of sealing end 4 can change as required.In conjunction with Fig. 2 referring to Fig. 4.On the described seal closure 1 flange 200 is arranged.Flange 5 can be done widelyer, and formation can be hooked the position 203 of flange, and the part that flange 5 down extends can be hooked the flange 200 on the seal closure 1.

For seal closure 1 is combined on the flange 5 more firmly, there is depression position 202 at described envelope flange 200 middle parts, and depression has Raschig ring 201 in the position 202.It is 6 millimeters circular pit that the degree of depth can be made in depression position 202, Raschig ring 201 available metal made, Raschig ring 201 snap in depression position 202 can be further fixing flange 5.In addition, Raschig ring 201 also can connect seal closure 1 and flange 5 by modes such as butt-joints after snapping in depression position 202.

When Raschig ring 201 connects seal closure 1 and flange 5 in the butt-joint mode, can after finishing the butt-joint operation, in Raschig ring 201 and seal closure 1 gap, add sealing glue.Sealing glue also can enter between convex tendon 6 and the groove 3 in shell 2.

There are sealing end 4 and seal closure 1 in described shell 2 two ends.Shell 2 both can have sealing end 4 and seal closure 1 by an end, also can sealing end 4 and seal closure 1 all be arranged two ends.
