Abstract
The utility model discloses a package lithium-ion battery, comprising a battery electrical core, a circuit protection plate PCM connected with the anode and cathode terminals of the electrical core, a flexible circuit board FPC arranged on and fixedly connected with the circuit protection plate. And the free end of the flexible circuit board FPC is provided with a gold-plate sheet for power supply output and a rigid panel strengthening the intensity of the gold-plate sheet. The utility model has the advantages that the flexible circuit board FPC switches on the inner power supply of the battery and the power supply input of the electric appliance, because the extensibility of the flexible circuit board FPC is good, the position of the gold-plate sheet as the output terminal of the power supply can be properly adjusted, so that the power supply inputs fixed on the electric appliance and the sheet steel can achieve good electrical connection without strict acquirement of the position of the output terminal of the power supply in prior art, and the volume of the flexible circuit board is small, the package lithium-ion battery has the advantages of occupying no space and achieving the power supply output in extremely small space.
Description
Technical field
The utility model relates to a kind of lithium ion battery, is specifically related to the encapsulating structure of the power supply output of lithium ion battery.
Background technology
At present, lithium ion battery is widely used in industry-by-industry as a kind of high efficient energy sources carrier, especially communication, electron trade.All use lithium ion battery as present battery of mobile phone.Usually, lithium ion battery is also the same with other batteries in use, encapsulates out-put supply again by battery case or similar installation sleeve.In the past, the power supply of battery output generally was to realize (as the PHS mobile phone battery) by lead, utilized lead that the power output end of inside battery is connected with the power input of mobile phone and realized electrical connection.Because lead can freely be located, so when packaged battery, do not need the power supply outgoing position of strict control inside battery.But the lead volume that the method adopts is bigger, and also need bend, thereby causes settling on mobile phone the space of battery bigger.In order to address this problem; the output of existing battery of mobile phone power supply utilizes the output of route protection plate; as China Patent No. is 200620062915.6 to disclose a kind of encapsulating structure of battery battery core; the protective circuit substrate that is arranged on the battery cover wherein is provided with sheet metal (being commonly called as golden finger); the protective circuit substrate is connected with electric core both positive and negative polarity, and sheet metal is as the terminal of power supply output.Because sheet metal is thin, this power supply way of output does not take up space, but in order better to make good being electrically connected of oriented input realization on sheet metal and the mobile phone, then necessarily requires the position of sheet metal.
The utility model content
The technical problem that the utility model need solve provides a kind of easy to use, and can solve the encapsulation lithium ion battery of above-mentioned described space problem and outgoing position restricted problem.
For solving above-mentioned technical problem; the utility model has designed a kind of encapsulation lithium ion battery; comprise battery battery core, the route protection plate PCM that is connected with electric core anode and cathode terminals; online circuit protecting board is provided with a fixedly connected with it flexible PCB FPC, and the free end of flexible PCB FPC is provided with the gold plating film of power supply source output.
As further improvement of the utility model, on the gold plating film of power supply source output, also be provided with the steel disc that matches, hardness in the time of can strengthening gold plating film as power output terminal like this and contact with the power input of electrical appliance, thereby the position is more accurate when making the gold plating film location, and contact is better.
Further improve again as of the present utility model, on described route protection plate PCM, also be provided with the thermistor of the temperature that detects electric core and baffle PCM.It can detect the temperature of electric core and baffle, and transmission information in time is to main frame, and automatic shutdown circuit when reaching temperature limitation guarantees Electrical Safety.
The utility model utilizes flexible PCB FPC to fixedly connected with the protection circuit baffle, and the power output terminal that is provided with on the free end of flexible PCB FPC, thereby realizes confessing power supply.Because the ductility of this flexible PCB FPC is good, can suitably adjust position as the gold plating film of power output terminal, thereby make power input fixing on gold plating film and the electrical appliance realize good being electrically connected, need not the position that the picture prior art is strict with power output terminal; Because the volume of this flexible PCB is also little, do not take up space again, can in minimum space, realize power supply output.Therefore, the utility model problem that can solve outgoing position restriction can solve space problem again.
Description of drawings
Fig. 1 is the decomposing schematic representation of each part after the utility model embodiment assembling;
Fig. 2 is the schematic diagram that the utility model embodiment has assembled.
Embodiment
Below in conjunction with accompanying drawing the utility model being done one describes in detail.
As depicted in figs. 1 and 2; be the utility model embodiment; a kind of encapsulation lithium ion battery; comprise battery battery core 1; the route protection plate PCM 2 that is connected with electric core anode and cathode terminals; online circuit protecting board 2 is provided with a fixedly connected with it flexible PCB FPC 3; the free end of flexible PCB FPC 3 is provided with the gold plating film 4 of power supply source output; also have three steel discs (4 ') that match on the gold plating film 4; hardness in the time of can strengthening gold plating film as power output terminal like this and contact with the power input of electrical appliance; thereby the position is more accurate when making the gold plating film location, and contact is better.On described route protection plate PCM 2, also be provided with the thermistor 5 of the temperature that detects electric core 1 and baffle PCM.It can detect the temperature of electric core 1 and baffle 2, and transmission information in time is to main frame, and automatic shutdown circuit when reaching temperature limitation guarantees Electrical Safety.In order to protect and fixing these above parts, this battery also is provided with the high tempreture tape 6 that one deck wraps up above part.
The ductility of flexible PCB FPC of the present utility model is good, can suitably adjust position as the gold plating film of power output terminal, thereby make input fixing on gold plating film and the electrical appliance realize good being electrically connected, need not the position that the picture prior art is strict with power output terminal; And the volume of this flexible PCB is also little, does not take up space, and can realize power supply output in minimum space.In sum, the utility model problem that can solve outgoing position restriction can solve space problem again.
The above only is the execution mode of the invention, should be pointed out that for the person of ordinary skill of the art, under the prerequisite that does not break away from the invention design, can also make some changes and improvement, and these all belong to protection range of the present utility model.
