Description
Technical field
The utility model belongs to technical field of lithium ion, particularly relates to a kind of no glue sealed type lithium ion power battery cap
Background technology
At present, characteristics such as lithium ion battery has that volume is little, in light weight, electric weight is strong, memoryless, environmental protection are widely used in industrial production and the daily life.Existing lithium ion power battery cap comprises top cover, explosion-proof diaphragm, packing ring and orifice plate, and top cover and explosion-proof diaphragm, packing ring and orifice plate are combined successively.Existing block itself and solve with sealing problem employing gluing mode between itself and battery case.Because there is serious problem of aging in glue itself, its ageing time is significantly less than the useful life of battery itself, thereby battery sealing problem will occur early behind the gluing.Particularly having under the external force effect, the shortcoming of this glue will be more obvious.This battery anti-overflow technical problem can directly reduce the performance rate of battery, has potential safety hazard, even can cause a serious accident etc.
Summary of the invention
The utility model provides a kind of no glue sealed type lithium ion power battery cap for solving the technical problem that exists in the known technology.
The purpose of this utility model provides a kind of sealingly secure problem that solves battery, and it is excellent that the electrokinetic cell of assembling has the anti-overflow performance, safe class height, long service life, the no glue sealed type lithium ion power battery cap of characteristics such as applied widely.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of no glue sealed type lithium ion power battery cap comprises top cover, explosion-proof diaphragm, packing ring and orifice plate, and top cover and explosion-proof diaphragm, packing ring and orifice plate are combined successively, are characterized in: the curved-surface structure contact-making surface is arranged between outside seal circle and packing ring.
The utility model can also adopt following technical scheme:
Described no glue sealed type lithium ion power battery cap is characterized in: curved-surface structure is that integral circular shape, cross section are trapezoidal or semicircular structure.
Described no glue sealed type lithium ion power battery cap is characterized in: it is the boss of trapezoidal or semicircular structure that sealing ring has the cross section, and it is the groove of trapezoidal or semicircular structure that packing ring has the cross section.
Described no glue sealed type lithium ion power battery cap, be characterized in: the sealing ring sidewall has the anti-overflow groove.
Advantage and the good effect that the utlity model has are:
No glue sealed type lithium ion power battery cap is owing to adopted the utility model brand-new technology scheme, compared with prior art, solve existing block itself and with the contacted sealing problem of battery container, technical problems such as coating technique route complexity, production cost height, production efficiency be low have been avoided, especially aging fast behind the gluing, the easier appearance that causes this problem.Therefore, improve the anti-overflow security performance grade of electrokinetic cell greatly.
Characteristics simple in structure, easy to use, stable performance that this power battery cap has.To have the anti-overflow performance excellent for the electrokinetic cell of assembling, safe class height, long service life, advantage such as applied widely.

Embodiment
For further understanding utility model content of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
A kind of no glue sealed type lithium ion power battery cap comprises top cover 1, explosion-proof diaphragm 2, packing ring 3 and orifice plate 6, and top cover 1 is combined successively with explosion-proof diaphragm 2, packing ring 3 and orifice plate 6.3 on its outside seal circle 5 and packing ring have the curved-surface structure contact-making surface.Curved-surface structure is that integral circular shape, cross section are trapezium structure.Sealing ring 5 has the boss of trapezium structure, and packing ring 3 has the groove of trapezium structure.With the contacted sealing ring 5 of battery container sidewall anti-overflow groove 9 is arranged.
The concrete mounting structure and the course of processing of present embodiment: as shown in the figure, electrokinetic cell combination mounting structure comprises: top cover 1, explosion-proof diaphragm 2, packing ring 3, battery case 4, sealing ring 5, orifice plate 6, base 7, anti-explosion membrane notching 8, sidewall anti-overflow groove 9 are pressed in the top cover hole, laser solder joint 10, bottom seal boss 11, orifice plate indentation 12, laser solder joint 13.The block of present embodiment, its outside have sealing ring 5 and 3 on packing ring that the curved-surface structure contact-making surface is arranged.Curved-surface structure is that integral circular shape, cross section are trapezium structure.Sealing ring 5 has the boss of trapezium structure, and packing ring 3 has the groove of trapezium structure.With the contacted sealing ring 5 of battery container sidewall anti-overflow groove 9 is arranged.Since sealing ring 5 and 3 on packing ring have the curved-surface structure contact-making surface and with the contacted sealing ring 5 sidewall anti-overflow grooves 9 of battery container, thereby guaranteed capping structure and the contacted sealing problem of battery container, guaranteed the contacted sealing property of block and battery container.Avoided aging fast behind technical problem, the especially gluings such as coating technique route complexity, production cost height, production efficiency be low, the easier appearance that causes this problem.Therefore, improve the anti-overflow security performance grade of electrokinetic cell greatly.
Characteristics simple in structure, easy to use, stable performance that this power battery cap has. The electrokinetic cell of assembling has anti-overflow superior performance, safe class height, long service life, the advantage such as applied widely.
