Description
Technical field
The utility model relates to a kind of Li-ion batteries piles.
Background technology
Lithium ion battery has that voltage is high, specific energy is high, recycles often, memory time is long, the size advantage such as little on year-on-year basis, on a portable electronic device as mobile phone, bluetooth earphone, MP3, MP4, MP5, Digital Video and laptop computer etc. are widely applied.Along with increasing and lightness of end product function, the requirement that volume is little, quality is light and stand-by time is long is proposed to lithium-ions battery group.
Li-ion batteries piles has housing, lithium ion battery and protective circuit plate usually.When producing such Li-ion batteries piles, usually on housing, integrated injection molding forms the contact of Li-ion batteries piles, thus when producing the housing of Li-ion batteries piles, the mould used is complicated, shell processing casting technique is complicated, the mach rate of finished products of mould is low thus, and the rate of finished products of the shell of casting is also low.Therefore waste resource, cost is high.
Summary of the invention
The utility model proposes for problems of the prior art, and its object is to provides a kind of processing simple, the Li-ion batteries piles that rate of finished products is high.
Following technical scheme is adopted for realizing the purpose of this utility model.
The Li-ion batteries piles of technical scheme 1; there is housing, lithium ion battery and protective circuit plate; described housing comprises lower drain pan and cap; battery case is formed in the bottom of described lower drain pan; in described battery case, be equipped with lithium ion battery, be connected with protective circuit plate in one end of described lithium ion battery, described protective circuit plate is arranged on the side of described lower drain pan; described protective circuit plate is formed with contact, and described contact is from the through hole be formed in described side to exposing outside.
The Li-ion batteries piles of technical scheme 2, in the Li-ion batteries piles of technical scheme 1, is formed with multiple described battery case in the bottom of described lower drain pan, after being contained in series connection in multiple described battery case and/or parallel connection, is connected with described protective circuit plate.
The Li-ion batteries piles of technical scheme 3, in the Li-ion batteries piles of technical scheme 2, described lower drain pan and described cap are welded together.
Compared with prior art, the utility model has following beneficial effect.
According to the Li-ion batteries piles of technical scheme 1, contact does not form as one with housing, and is formed on protective circuit plate, and protective circuit plate is arranged on the side of housing, side is formed the through hole that contact is exposed, carries out input and output thus.Because contact does not form one with housing, so do not need complicated mould and casting technique, thus reduce shell difficulty of processing, shell rate of finished products improves all greatly.And on baffle, paste the technical maturity of nickel contact, cost of manufacture is lower, and rate of finished products is high.Can also reduce combination operation step in addition, reduce the frequency using high-temperature electric flatiron, combination rate of finished products also improves greatly, thus economizes on resources, and reduces costs.
In addition, according to the Li-ion batteries piles of technical scheme 2, form multiple battery case in the housing, thus can accommodating multiple lithium ion battery, thus the capacity of battery pack can be improved, be applicable to the power consumption equipment of high power capacity requirement.
In addition, according to the Li-ion batteries piles of technical scheme 3, lower drain pan and cap pass through together with ultrasonic fusing, therefore manufacture simple production rate high.
Accompanying drawing explanation
Fig. 1 is the schematic perspective view representing Li-ion batteries piles of the present utility model.
Fig. 2 is the exploded perspective schematic diagram representing Li-ion batteries piles of the present utility model.
Embodiment
Below, based on accompanying drawing, the Li-ion batteries piles as an example of the present utility model is described.
Fig. 1 is the schematic perspective view representing Li-ion batteries piles of the present utility model.Fig. 2 is the exploded perspective schematic diagram representing Li-ion batteries piles of the present utility model.
As depicted in figs. 1 and 2, Li-ion batteries piles of the present utility model has housing 10, lithium ion battery 20 and protective circuit plate 30.
Housing 10 comprises lower drain pan 11 and cap 12; battery case 110 is formed in the bottom of lower drain pan 11; lithium ion battery 20 is equipped with in battery case 110; protective circuit plate 30 is connected with in one end of lithium ion battery 20; protective circuit plate 30 is arranged on the side of lower drain pan 11; protective circuit plate 30 is formed contact 31,32, and input 31,32 is from the through hole 111 be formed in side to exposing outside.When battery discharge, contact is for exporting contact, and when charging to battery, contact is input contact.
Specifically, Li-ion batteries piles comprises lower drain pan, cap, cylindrical single lithium battery, protective circuit plate.Cell is by being connected to the relevant position of protective circuit plate after wire and nickel strap connection in series-parallel; entirety is placed in lower drain pan again; in lower drain pan, draw-in groove is set; protective circuit plate is fixed to lower drain pan front end; the contact on baffle is enable to be placed on correct input and output position; cover cap, after ultrasonic bonding, lower drain pan, cap become to be integrated, and are combined into a kind of lithium-ions battery group with contact thus.
Li-ion batteries piles gauge of the present utility model is less, only has 21.5mm, can be installed in less equipment cavity, adopts contact input and output, can with contact pilotage good contact, for equipment provides power supply.
According to above-mentioned Li-ion batteries piles, contact does not form as one with housing, and is formed on protective circuit plate, and protective circuit plate is arranged on the side of housing, side is formed the through hole that contact is exposed, carries out input and output thus.Because contact does not form one with housing, so do not need complicated mould and casting technique, thus reduce shell difficulty of processing, shell rate of finished products improves all greatly.And on baffle, paste the technical maturity of nickel contact, cost of manufacture is lower, and rate of finished products is high.Can also reduce combination operation step in addition, reduce the frequency using high-temperature electric flatiron, combination rate of finished products also improves greatly, thus economizes on resources, and reduces costs.
In addition, multiple battery case can be formed with in the bottom of lower drain pan, after being contained in series connection in multiple battery case and/or parallel connection, be connected with protective circuit plate.Thus the capacity of battery pack can be improved, be applicable to the power consumption equipment of high power capacity requirement.Certainly, battery case can be one, as long as can carry out input and output.
In addition, lower drain pan and cap can be welded together, and therefore manufacture simple production rate high.Welded by ultrasonic wave in the present embodiment, but be not limited thereto, can be welded by other welding mode.
Above the Li-ion batteries piles of preferred implementation of the present utility model is illustrated, but the utility model is not limited to above-mentioned concrete execution mode, only otherwise depart from the scope of claim, can various distortion or change be carried out.The utility model comprises various distortion within the scope of the claims and change.
