Description
Technical field
The utility model relates to a kind of lithium ion battery.
Background technology
Lithium ion battery is as a kind of novel high power capacity, and safety, environmental protection, free of contamination rechargeable battery have obtained using widely in recent years in equipment such as mobile phone, notebook computer, PDA, have become the standard configuration of these electronic equipments.
Lithium ion battery generally partly is made up of electric core, battery protecting plate and plastic shell etc.Battery protecting plate places between enclosure interior electricity core and the housing.Plastic shell is used for fixing the relative position of electric core and battery protecting plate and the protective circuit plate is protected.The inside of electricity core includes positive and negative plate, barrier film and electrolyte, is provided with the positive and negative lug that links to each other with inner positive and negative plate respectively in the outside of electric core.Positive and negative lug is electrically connected with terminal on the battery protecting plate, and the terminal on the battery protecting plate is electrically connected with extraneous load or charging circuit.The battery of this mode is owing to the plastic shell that needs to make separately, thereby cost is higher, and the process that is assembled into the battery finished product by electric core is also comparatively complicated, inconvenient.
Application number is " 02802558.X ", and the Chinese patent application that name is called " battery and battery pack " discloses a kind of battery structure, has saved plastic shell, and (has descended) end that end cap is set on electric core.End cap adopts the mode of whole encapsulating to make, simultaneously the battery protecting plate fixing glue between end cap and electric core.The defective of this mode is: the manufacturing process more complicated of whole encapsulating, cost is also higher, and the firm degree that combines between end cap and the electric core is also lower, and because end cap adopts the low-temp low-pressure injection mo(u)lding, the head intensity difference of end cap influences the serviceability of battery.
Application number is " 03247291.9 ", name is called the Chinese patent application of " lithium ion battery " and has announced a kind of lithium ion battery structure, adopt the end cap of independent moulding, and adopt screw that end cap and electric core are connected and fixed, can overcome the defective of the head intensity difference of end cap, and strengthen the firm degree of end cap and electric core combination.But this defective that to be mode exist is, needs the turn of the screw during assembling, and parts are many, the assembly manipulation trouble, and the cost height, and also the existence of screw hole causes occurring the phenomenon of leakage easily, influences the rate of finished products of battery.
Summary of the invention
The technical problem that will solve of the present utility model is to overcome above defective, proposes a kind of lithium ion battery, and technology is simple, is connected reliably between end cap and electric core.
Technical problem of the present utility model is solved by the following technical programs.
This lithium ion battery comprises electric core, battery protecting plate and end cap; described battery protecting plate is electrically connected with the positive and negative lug of electric core; the side of described end cap has mounting groove; described battery protecting plate inserts in the mounting groove, also adopts the PUR injection moulding to fix between described electric core, battery protecting plate and the end cap.
In another preferred scheme, in the above-mentioned lithium ion battery, described end cap is the hard plastic lid of high-temperature injection moulding.
The upper wall of described mounting groove offers first and dodges mouth; be used to expose power connection end on the battery protecting plate; the lower wall of described mounting groove offers second and dodges mouth, is used to dodge components and parts and the convenient positive and negative lug that welds battery protecting plate and electric core on the battery protecting plate.
Fix for the low-temp low-pressure injection moulding between described electric core, battery protecting plate and the end cap.
The utility model is compared with the prior art the beneficial effect that is had: the battery protecting plate insertion end is covered in the mounting groove of offering; assembling easily; connect firm; can not be offset; the problem of end cap and battery protecting plate contraposition when having solved assembling; need not the turn of the screw, can not damage electric core or cause electric core leakage, technology is simpler.End cap adopts hard plastics to make, and has guaranteed the intensity of end cap head, satisfies battery and uses needs.
