Description
Technical field
The utility model relates to a kind of internal structure of lithium battery, particularly relates to a kind of lithium battery insulation system.
Background technology
Lithium battery is mainly used in the electrical appliance fields that capacity required is large, the storage time is long, operating temperature range is wide such as camera, cigarette sense siren, gas meter, ammeter, water meter.Tradition lithium battery comprises metal shell, curling product, seal body; Curling product comprise positive plate, negative plate and barrier film, curling product are drawn the positive pole ear be connected with positive terminal and the negative lug be connected with negative pole end.Be provided with sealing ring on the downside of seal body, sealing circle, in order to isolated metal shell and seal body, prevents leakage simultaneously.Metal shell is provided with to the annular groove groove holding sealing ring.In lithium battery; metal shell (comprising annular groove groove) is negative pole polarity; and annular groove groove is in concave configuration; machine is formed in the process of annular groove groove in extruding; usually can extrude curling product; cause the positive plate in curling product to poke barrier film outside exposed, the inwall of annular groove groove easily directly contacts with positive plate, causes battery short circuit.In order to overcome this shortcoming, an annular insulating trip can be placed above curling product, for the contact of isolated positive plate and annular groove groove inwall.
Annular insulation film instead of extruding when curling product are directly subject to annular groove slot machining process, can completely cut off because of unexpected exposed positive plate and annular groove groove contact internal walls simultaneously, cause battery short circuit.There is following shortcoming in existing annular insulation film: 1, hollow annular insulation film due to supportive poor, annular insulation film is very easily squeezed at groove processing link, annular insulation film ejects in metal shell because extruding bending, affects the normal production of lithium battery.2, battery is when sealing, and needs the positive pole ear bending originally erectting, if the positive plate in curling product because of pressurized exposed, bending positive terminal probably makes the positive plate pressurized given prominence to encounter negative pole, causes the short circuit of lithium battery, affects battery life.
Utility model content
Technical problem to be solved in the utility model is to provide the lithium battery insulation system that a kind of insulating trip can not eject in metal shell because of extruding, and this insulation system more effectively can play the effect of electric isolution simultaneously.
The utility model solves the problems of the technologies described above adopted technical scheme: lithium battery insulation system, it is characterized in that comprising the insulating trip be positioned at above curling product, this insulating trip is positioned at the downside of annular groove groove, insulation division comprises basic ring, be provided with many reinforcements of flat structure in described basic ring, there is in basic ring a unobstructed region of drawing for positive pole ear.
The further preferred version of the utility model: the center of described insulating trip is provided with flat matrix, described reinforcement radial distribution and being connected with described matrix.The support strength of reinforcement is better, effectively can prevent flexural deformation, thus avoid ejecting in metal shell.
The further preferred version of the utility model: described matrix center is provided with the air vent hole can discharged for battery reacting gas.The gas that lithium battery produces in course of reaction can be discharged smoothly from air vent hole, and can not be reinforced muscle and covered.
The further preferred version of the utility model: many articles of reinforcements comprise the first reinforcement, the second reinforcement and the 3rd reinforcement, first reinforcement and the 3rd reinforcement are on same straight line and form main reinforcement, unobstructed region is positioned at the side of main reinforcement, second reinforcement is positioned at the opposite side of main reinforcement, and the second reinforcement is between the first reinforcement and the 3rd reinforcement.The arrangement of reinforcement reserves the extraction location of positive pole ear simultaneously, and this reinforcement can increase the intensity of insulating trip effectively, prevents deformation.
The further preferred version of the utility model: the rear end of positive pole ear is enclosed with adhesive tape, the bare front end of described positive pole ear, after bending, the positive pole ear of exposed part is positioned at the top of the second reinforcement.Isolated by the second reinforcement between positive pole ear and curling product, can effectively avoid positive pole ear to contact with curling product.
The further preferred version of the utility model: described matrix ovalize, one end of the first reinforcement is connected the major semiaxis of matrix with one end of the 3rd reinforcement, one end of the second reinforcement connects the semi-minor axis of matrix.
The further preferred version of the utility model: the first described reinforcement, the second reinforcement are identical with the thickness of the 3rd reinforcement, the width of the second reinforcement is greater than the width of the first reinforcement and the 3rd reinforcement.The whole insulating trip of the identical guarantee of thickness of reinforcement is placed on above curling product stably; Second reinforcement can provide enough large insulation area to prevent the positive pole ear of bending from touching curling product.
Compared with prior art, the utility model has the advantage of that insulating trip can completely cut off the contact between the exposed positive plate of accident on curling product and annular groove groove inwall; The insulating trip with reinforcement is positioned on curling product, insulating trip is made to have better support force and intensity, insulating trip can not bend because of the extruding of housing (groove slot machining link) to such an extent as to ejects in metal shell or leave original position, and the second reinforcement of insulating trip can more effectively avoid positive pole ear to contact with curling product.
