Description
Technical field
The utility model belongs to the technical field that battery core is used instead, and in particular to a kind of battery core uses the adaptation of general battery instead
Device.
Background technique
It is wide in many universal battery application fields since the applicating history of universal one-shot battery is longer and has been standardized
General use, such as illuminations are seen and take aim at equipment, photographic goods and instrument and meter.Wherein, the most widely used is model
CR123A battery.CR123A battery is disposable lithium cell, not reproducible use, thus always exists use cost height and give up
Abandon the problem that pollution not environmentally waits.
Currently, to solve the not re-usable defect of one-shot battery, using a kind of lithium ion battery (secondary cell) generation
For existing disposable battery.Although solving the not re-usable defect of battery, there are still many for the alternative scheme
Problem is simultaneously not perfect, specifically discloses correlation existing for the alternative scheme it has been known that there is the citing of the actual product of two class batteries with market
Defect:
The first kind: the industrial 16340 chargeable chargeable lithium cells in lithium cell/16650.
16340 battery cores are cobalt acid lithium battery, nominal voltage 3.7V, fully charged 4.2V, higher than the 3V power supply of CR123A battery.
The output voltage of existing lithium ion battery and one-shot battery difference, are easily damaged electrical equipment.
16650 battery cores are cobalt acid lithium batteries, and nominal voltage 3.7V, fully charged 4.2V are usually used in a section while replacing two sections
CR123A battery.But single-unit nominal voltage 3.8V is lower than two section CR123A battery 6V, using in two section CR123A electricity of original design
In the equipment in pond, discharging efficiency and cruise duration all have a greatly reduced quality.
Second class: RCR123A rechargeable lithium battery.
Improvement battery of the RCR123A battery based on existing battery core, by installing drop additional in the bottom of 16340 battery cores, that is, cathode
Pressing plate realizes 3V voltage output.But what the defect of RCR123A battery was also apparent from, first is that capacity is small and decompression loss is big,
Cruise duration is far below CR123A battery.Second is that decompression board power is small and heat dissipation is bad, and discharge stability is less than CR123A

When opening, adaptation loops are disconnected, so that the connection of adapter and battery core cathode disconnects, adapter circuit is only connected to the anode of battery core,
It stops working.It is opened and closed by the switch of load circuit, and then is switched on or switched off the cathode of adapter circuit and the connection of battery core cathode,
It is closed at and is disconnected load circuit, realizes the output operation of control adapter circuit, it is suitable to realize control by existing structure
Channel with circuit simplifies the electrical composition of adapter.
The utility model is not limited in the channel of the switch control adaptation loops by load circuit, if electrical equipment without
Switch, the on-off of adaptation loops can be realized in the loading and disassembly of general battery.
Existing battery (such as RCR123A), decompression board or protection board and battery core are integrated plastic packagings, while in battery
The home loop of decompression board or protection board is the positive and negative anodes for being continuously turned on battery core, is constantly in underloading discharge condition, leads to electricity
The self discharge in pond is rapid, and it is poor to deposit electrical property.And the technique of integrated plastic packaging causes heat dissipation effect to be short of, so that discharge stability
Difference.
Compared with prior art.Adapter provided by the utility model is independent from each other with battery core, and adapter can be with
Any battery core is combined use.Meanwhile the general battery being composed, adapter and battery core are no electrical communications, are fitted
Cathode with circuit needs the cathode of the load connection battery core by electrical equipment.It is constituted using the adapter of the utility model
General battery, normal storage or it is standby when, the advantages of all having no self discharge.Adapter circuit, which will not voluntarily work, to be caused to put certainly
Electricity.It needs to be packed into electrical equipment in this general battery, and when closure switch, indirect connects adapter circuit and battery core cathode
Adaptation loops just meet the work starting needs of adapter.And existing battery cannot achieve.Meanwhile the present embodiment
The metal outer of metal ring cradles monolith PCB, sufficiently guides the heat generated under the high power of adapter circuit.Market
The decompression board one plastic packaging of existing RCR123A battery cannot achieve.
