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 the portable terminal that comprises it.
Background technology
Rechargeable battery plays an important role in portable terminal as a kind of energy storage device, its some performance parameters, for example capacity, for 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, for example existing battery of mobile phone 1 comprises a battery core 11 and a circuit board 12, the two ends of this circuit board 12 link to each other 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, with those golden finger 121 and circuit board of mobile phone electric connection.During use, please be 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.
Existing mobile phone the situation of signal of telecommunication shakiness often occurs when making a phone call.Under extreme case, even the situation of unexpected power down appears.Similarly, in other mobile internet surfing equipment (MID, Mobile Internet Device), for example in panel computer or the notebook computer, also exist similar situation.Moreover the automatic shutdown of portable terminal and power-off problems are perplexing the research staff in rechargeable battery field always.
Summary of the invention
The technical problem to be solved in the present invention is the defective for the automatic shutdown that overcomes portable terminal of the prior art and power down, a kind of rechargeable battery and the portable terminal that comprises it are provided, use the portable terminal of this rechargeable battery automatic shutdown and power-off problems can not occur.
The present invention solves above-mentioned technical problem by following technical proposals:
A kind of rechargeable battery comprises a battery core, three golden fingers and a protective circuit plate, and this battery core is cuboid, and its characteristics are that 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 and this protective circuit plate.
The present invention also provides a kind of portable terminal, comprises a battery mounting groove, and its characteristics are, are provided with aforesaid rechargeable battery in this battery mounting groove.
Preferably, this portable terminal is mobile phone or panel computer.
Positive progressive effect of the present invention is: by those golden fingers and this protective circuit plate are arranged at respectively on the different surfaces of this battery core; so that in the situation that those golden fingers and mobile terminal circuit plate closely electrically contact, this protective circuit plate but can be away from the mobile terminal circuit plate.Thereby prevented that the signal that comes from the mobile terminal circuit plate from disturbing, and effectively solved portable terminal automatic shutdown and power-off problems, improved simultaneously the stability of the output voltage of rechargeable battery.

Embodiment
Mode below by embodiment further specifies the present invention, but does not therefore limit the present invention among the described scope of embodiments.
As shown in Figure 3; the rechargeable battery 2 of present embodiment comprises the battery core 21 of a cuboid, three golden fingers 222 and a protective circuit plate 221; those golden fingers 222 and this protective circuit plate 221 are arranged at respectively on two adjacent surfaces of this cuboid; and be electrically connected by Rigid Flex between the two, Rigid Flex is the technical term of this area.During actual fabrication; can also adopt those golden fingers 222 and this protective circuit plate 221 to be arranged at respectively two relative lip-deep versions of this cuboid; and also can pass through flexible printed circuit board (Flexible Printed Circuit, FPC) between the two is electrically connected.
By those golden fingers 222 and this protective circuit plate 221 are arranged at respectively on the different surfaces of this battery core 21; so that the metal contact of those golden fingers 222 and mobile terminal circuit plate offsets and closely is affixed; and this protective circuit plate 221 is away from the mobile terminal circuit plate; prevented from coming from the interference of the radiofrequency signal of mobile terminal circuit plate; therefore automatic shutdown and the power-off problems of portable terminal are solved, and the stability of output voltage is improved.
The structural design of the rechargeable battery of present embodiment is based on the basis of following test and analysis:
In automatic shutdown and power-off problems situation, on the basis of using one by one parts Shift Method and analysis, failure cause is contracted to battery of mobile phone.Please understand in conjunction with Fig. 1-2 and Fig. 4, when making a phone call, the ripple voltage of existing battery of mobile phone has surpassed 1 volt (being 1000mV).And the standard value of the ripple voltage of battery of mobile phone should be for below the 400mV; therefore by further analyzing this battery core 11, those golden fingers 121, this protective circuit plate 122, resettable fuse, thermistor and nickel strap, further reason is contracted to this protective circuit plate 122.Find through research; in the situation of using copper film shielded firmly this protective circuit plate 122; automatic shutdown and power-off problems disappear; thereby infer that further this protective circuit plate 122 is subject to the conclusion that radio-frequency antenna disturbs on the circuit board of mobile phone, and proposed those golden fingers 121 and this protective circuit plate 122 are arranged at the technical scheme of the different surfaces of this battery core.
In a word, the improvement of the rechargeable battery of present embodiment needs a large amount of optionally experimental study and tight rational analyses.In addition, the rechargeable battery of present embodiment has also been obtained preferably technique effect.Please understand in conjunction with Fig. 5, when making a phone call, the ripple voltage of the rechargeable battery of present embodiment is 300mV only, is lower than the ripple voltage standard value 400mV of battery of mobile phone.
Present embodiment also provides a kind of portable terminal, and this portable terminal comprises a battery mounting groove and aforesaid rechargeable battery.This portable terminal can be mobile phone, also can be panel computer.
Although more than described 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 limited by appended claims.Those skilled in the art can make various changes or modifications to these execution modes under the prerequisite that does not deviate from principle of the present invention and essence, but these changes and modification all fall into protection scope of the present invention.
