Description
Technical field
The utility model relates to a kind of anode end cap structure of battery, a kind of blast resistance construction of anode end cap specifically.
Background technology
Along with the extensive use of battery, the potential safety hazard that battery brings is also more and more.After through long the use, the electric conducting material of inside battery can produce chemical reaction, forms higher atmospheric pressure at inside battery easily.Battery case is standing under the situation of atmospheric pressure, perhaps can produce distortion or continue accumulated gas to form higher atmospheric pressure, and after accumulating to a certain amount of gas, battery might produce the problem of blast, has brought potential safety hazard to people.
The utility model content
The purpose of this utility model provides a kind of battery anti-explosion positive cover structure, solves that inside battery air pressure raises and the problem of the blast that brings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of battery anti-explosion positive cover structure, comprise the sealing enclosing cover that embeds the galvanic anode end, at the inner installation of sealing enclosing cover conducting strip with holes, thermosensitive resistor film and positive cover, described positive cover is positioned at the outside, conducting strip with holes is positioned at inside, between positive cover and the thermosensitive resistor film pad is installed, thermosensitive resistor film is connected by die casting point with the central authorities of conducting strip with holes, and form the depression of taper in the central authorities of thermosensitive resistor film, described conducting strip with holes is fixed on sealing enclosing cover inside by the insulation cushion rubber, the inner bottom part of sealing enclosing cover is provided with step, the insulation cushion rubber is embedded in the step, insulation cushion rubber and step support thermosensitive resistor film together, and described thermosensitive resistor film is provided with a circle indenture, and the tranverse sectional thickness at indenture place is less than the normal thickness of thermosensitive resistor film cross section.Described sealing enclosing cover and insulation cushion rubber adopt the insulating material manufacturing, and positive cover is provided with several uniform air-vents, and described conducting strip with holes is provided with several air-vents.Seal enclosing cover relatively and outwards be subjected to displacement in order to limit positive cover, can be provided with a circle fin in the inside of sealing enclosing cover, after the assembling, fin is positioned at the outside of positive cover, and perhaps, the outer setting of sealing enclosing cover becomes indent, encases positive cover.
Under the state that uses, conducting strip with holes directly contacts with the charging material of inside battery, if the air pressure of inside battery raises, thermosensitive resistor film is disconnected from indenture, and gas inside is discharged.Air-vent on conducting strip with holes and the positive cover can guarantee when gas is discharged accessible.
By design of the present utility model, battery anti-explosion positive cover structure is installed in the positive terminal of battery, can effectively prevent problem owing to the too high blast that produces of inside battery air pressure.
