Abstract
The utility model discloses a battery safety valve type pole rod which comprises a pole rod and a valve body. The valve body comprises a valve hole and an antidetonating membrane press piece, etc. The pole rod has blended with the safety valve into one whole. The valve body is provided inside the pole rod and is separated by insulating material. The pole rod is fixed on a battery cover from which the pole rod is insulated. A battery medium which can connect external conductors and prevent accidental explosion of the battery is a battery safety valve type pole rod which is not limited by the battery end size and can be installed on small capacity batteries freely. The pole rod is simple in structure and solves the problems that the battery safety is affected because the non one body safety valve body is not firmly welded on the battery cover or the relief pressure value of the battery can not be controled effectively because of limitation of the size of the battery shape.
Description
Technical field
The utility model belongs to the explosion protection for batteries applied technical field, particularly a kind of battery safety valve formula pole.
Background technology
Present known battery electrode column mostly is metal solid greatly and places metal battery to cover, and this kind pole can not solve the cell safety problem.Since the development lithium-ions battery, solved the cell safety problem and seemed particularly outstanding.As on battery case or battery cover, delineating trace, make its attenuation, reduce the compressive resistance of housing with this, when over-charging of battery, cross put, when abuse conditions such as overheated or short circuit causes cell internal pressure too high, above-mentioned position is out of shape, draws up and plays safety effect, and this simplicity of design is convenient, but shortcoming is owing to be subjected to the restriction of materials such as battery container or battery cover, be difficult to the pressure release value of control battery, so coefficient of safety can't guarantee also.Have, having on the battery cover of pole, the one or both sides that are positioned at pole are provided with safety law, and the pressure release value of this safety law may command battery can guarantee the fail safe of battery effectively, but its weak point is the restriction that is subjected to battery overall dimension.
Summary of the invention
The utility model provides a kind of coefficient of safety that both can guarantee battery for solving the problem that exists in the known technology, is not subjected to the battery safety valve formula pole of battery overall dimension restriction again.
The technical scheme that the utility model is taked for the problem that exists in the solution known technology is: battery safety valve formula pole, form by pole, valve body, valve body comprises valve opening, rupture pressure disc briquetting etc., and it is characterized in that: described pole and valve body are one, and valve body is positioned at pole.
The utility model can also take following technical measures to realize: the pole of described valve opening bottom is provided with horizontal through hole; Described valve opening is the stepped hole that macropore, aperture constitute; Described macropore is provided with the screw thread that is connected with briquetting, and the rupture pressure disc upper end that is arranged in the macropore is provided with explosion-proof packing ring, and the lower end is provided with explosion-proof packing ring; The cylinder that described pole does not have valve opening one end is a flat.
Advantage and the good effect that the utlity model has are: (1) pole and safety valve combine together, and be simple in structure, avoided safety valve body to influence the fail safe of battery admittedly because of not prison welding on battery cover; (2) not limited by battery overall dimension, can be installed in freely on the small-sized capacity battery; (3) can control the pressure release value of battery reliably.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
Please refer to accompanying drawing, select for use aluminium bar or other metal bar to block an end with lathe, the external diameter car is to pole 1 one end required size length, and process the external screw thread that is connected with lead, determine valve opening 2 diameters according to pressure release power size, valve opening 2 length add the summation of platform 5 length greater than pole 1 one end length, process the screwed hole that is connected with briquetting 6, unload rapidoprint, block a manufactured end, reserve the length of platform 5, the processing other end processes a cross-drilled hole 7 being close to the you face on other end cylinder, cross-drilled hole 7 communicates with valve opening 2, the cylinder of the other end is processed into flat, processes and the parallel hole of cross-drilled hole 7 center lines near the end, so that be connected with other positions of inside battery.Take off pole, pack into successively in valve opening 2 explosion-proof packing ring 3, rupture pressure disc 4, explosion-proof packing ring 3 connect briquetting 6 at last, promptly become complete battery safety valve pole.
Operating principle of the present utility model is: insulating material is fixed on pole on the battery cover pole and battery cover insulation.Pole can play the effect of connection outer lead in battery, can work preventing the effect of battery accidental explosion again, is a kind of battery end face size restrictions that is not subjected to, the battery safety valve pole that pole and safety valve combine together.
Claims (7)
