Abstract
The invention discloses a rechargeable battery and a mobile terminal including the same. The rechargeable battery comprises a battery cell, three connecting fingers and a protective circuit board. The battery cell is a cuboid, the connecting fingers are arranged on the first surface of the cuboid, and the protective circuit board is arranged on the second surface of the cuboid. The connecting fingers and the protective circuit board are arranged on the different surfaces of the battery cell, so that the connecting fingers and the circuit board of the mobile terminal are in close electrical contact, and the protective circuit board is kept away from the circuit board of the mobile terminal, thus preventing the signal interference derived from the circuit board of the mobile terminal, and problems of automatic shutdown and power-down of the mobile terminal are solved, and the output voltage stability is improved.
Description
Technical field
The present invention relates to wireless communication field, particularly a kind of rechargeable battery and comprise its mobile terminal.
Background technology
Rechargeable battery plays an important role in the terminal as a kind of energy storage device, its some performance parameters, and such as capacity, confession electrical stability and discharge and recharge number of times, be directly connected to stability and the useful life of mobile phone signal.
As shown in Figure 1, existing rechargeable battery, such as existing battery of mobile phone 1 comprises battery core 11 and a circuit board 12, and the two ends of this circuit board 12 are connected by the both positive and negative polarity of nickel strap with this battery core 11.As shown in Figure 2, this circuit board 12 comprises three golden fingers 121 and a protective circuit plate 122.During installation, by those golden fingers 121 and circuit board of mobile phone electric connection.During use, please simultaneously in conjunction with Fig. 1-2, this battery core 11 exports electric energy to those golden finger 121 by this protective circuit plate 122, and finally transfers to circuit board of mobile phone.This protective circuit plate 122 has regulated output voltage and electric current, prevents the function of super-charge super-discharge and high temperature protection.
When making a phone call, often there is the situation of signal of telecommunication shakiness in existing mobile phone.In extreme circumstances, even there is the situation of unexpected power down.Similarly, in other mobile internet surfing equipment (MID, MobileInternet Device), such as, in panel computer or notebook computer, also there is similar situation.Moreover the automatic shutdown of mobile terminal and power-off problems annoying the research staff in rechargeable battery field always.
Summary of the invention
The technical problem to be solved in the present invention is the defect in order to the automatic shutdown and power down overcoming mobile terminal of the prior art, a kind of rechargeable battery is provided and comprises its mobile terminal, use the mobile terminal of this rechargeable battery to there will not be automatic shutdown and power-off problems.
The present invention solves above-mentioned technical problem by following technical proposals:
A kind of rechargeable battery, comprise a battery core, three golden fingers and a protective circuit plate, this battery core is cuboid, and its feature is, those golden fingers are arranged on the first surface of this cuboid, and this protective circuit plate is arranged on the second surface of this cuboid.
Preferably, this first surface and this second surface are two adjacent surfaces.
Preferably, this first surface and this second surface are two relative surfaces.
Preferably, be electrically connected by Rigid Flex between those golden fingers with this protective circuit plate.
The present invention also provides a kind of mobile terminal, comprises a battery settling groove, and its feature is, is provided with rechargeable battery as above in this battery settling groove.
Preferably, this mobile terminal is mobile phone or panel computer.
Positive progressive effect of the present invention is: by those golden fingers and this protective circuit plate being arranged at respectively on the different surfaces of this battery core; make when those golden fingers and mobile terminal circuit plate intimate electrical contact, this protective circuit plate but can away from mobile terminal circuit plate.Thus prevent the signal disturbing coming from mobile terminal circuit plate, and efficiently solve mobile terminal automatic shutdown and power-off problems, improve the stability of the output voltage of rechargeable battery simultaneously.

Embodiment
Mode below by embodiment further illustrates the present invention, but does not therefore limit the present invention among described scope of embodiments.
As shown in Figure 3; the rechargeable battery 2 of the present embodiment comprises battery core 21, three golden fingers 222 and a protective circuit plate 221 of a cuboid; those golden fingers 222 and this protective circuit plate 221 are arranged on two adjacent surfaces of this cuboid respectively; and be electrically connected by Rigid Flex between the two, Rigid Flex is the technical term of this area.During actual fabrication; those golden fingers 222 and this protective circuit plate 221 can also be adopted to be arranged at version on two relative surfaces of this cuboid respectively; and also can pass through flexible printed circuit board (Flexible Printed Circuit, FPC) electrical connection between the two.
By those golden fingers 222 and this protective circuit plate 221 are arranged on the different surfaces of this battery core 21 respectively; those golden fingers 222 are made to offset with the metal contact of mobile terminal circuit plate and closely be affixed; and this protective circuit plate 221 is away from mobile terminal circuit plate; prevent the interference of the radiofrequency signal coming from mobile terminal circuit plate; therefore the automatic shutdown of mobile terminal and power-off problems are solved, and the stability of output voltage is improved.
The structural design of the rechargeable battery of the present embodiment is on the basis based on following testing and analysis:
Under automatic shutdown and power-off problems situation, by using on the basis of parts Shift Method and analysis one by one, failure cause is contracted to battery of mobile phone.Understand incorporated by reference to Fig. 1-2 and Fig. 4, when making a phone call, the ripple voltage of existing battery of mobile phone has exceeded 1 volt (i.e. 1000mV).And the standard value of the ripple voltage of battery of mobile phone should be below 400mV; therefore by further analyzing this battery core 11, those golden fingers 121, this protective circuit plate 122, resettable fuse, thermistor and nickel strap, reason is contracted to this protective circuit plate 122 further.Find through research; when using copper film shielded firmly this protective circuit plate 122; automatic shutdown and power-off problems disappear; thus infer that this protective circuit plate 122 is subject to the conclusion of radio-frequency antenna interference on circuit board of mobile phone further, and propose the technical scheme those golden fingers 121 and this protective circuit plate 122 being arranged at the different surfaces of this battery core.
In a word, the improvement of the rechargeable battery of the present embodiment needs a large amount of optionally experimental study and tight rational analysis.In addition, the rechargeable battery of the present embodiment also achieves good technique effect.Understand incorporated by reference to Fig. 5, when making a phone call, the ripple voltage of the rechargeable battery of the present embodiment is only 300mV, lower than the ripple voltage standard value 400mV of battery of mobile phone.
The present embodiment also provides a kind of mobile terminal, and this mobile terminal comprises a battery settling groove and rechargeable battery as above.This mobile terminal can be mobile phone, also can be panel computer.
Although the foregoing describe the specific embodiment of the present invention, it will be understood by those of skill in the art that these only illustrate, protection scope of the present invention is defined by the appended claims.Those skilled in the art, under the prerequisite not deviating from principle of the present invention and essence, can make various changes or modifications to these execution modes, but these change and amendment all falls into protection scope of the present invention.
