Abstract
In order to solve the problems that batteries can be directly connected in series into group and discharge of an instant heavy current and to ensure the safety of battery operation, the utility model provides a security package form. A sensor used for real-time temperature monitoring is added in the security package form, and a spring-inserted method of contact reliability is adopted in an output electrode of a battery. A firm electrode holder support is designed in a battery shell. An electrode of a battery core and an electrode of a sensor are independent output respectively and are not common-ground. The electrode holder support is integrated with the battery shell. A plug-in type of spring-inserted electrode is fixed firmly to lead the electrode irremovable in the direction of plug-in. The utility model has the advantage of reliable and security simple structure and is good for standardization.
Description
Affiliated technical field
The utility model relates to a kind of rechargeable battery secure package structure, especially a kind of electrokinetic cell secure package structure.
Background technology
At present; rechargeable battery is used widely in many industries; various secure package modes have also appearred; in the electrokinetic cell field; for the sake of security, the box hat packaged type of rechargeable battery is substituted by safer aluminum-plastic composite membrane packaged type, but this encapsulating structure is the form of initial stage in the battery production use; can't directly use, must be through could on market, using safely with safeguard protection in groups.
The battery of mobile phone encapsulating structure belongs to the typical a kind of secure package structure of digital domain; unless electric in-core portion suddenly-applied short circuit; otherwise the baffle in the battery case can effectively prevent protected electric core and overcharge, crosses and put or external short circuit; yet; problem when this encapsulating structure is not considered the work of electric core instantaneous large-current; and be a kind of single-unit electricity core working condition, more piece electricity core be can not satisfy equally and basic demand under the set condition, the use of can't directly connecting are connected into.
Electric tool and electric bicycle etc. are the battery powered system of basic load feature with the motor, require the necessary energy of battery transient large current discharge, and requiring the multiple batteries series connection to work in groups, existing rechargeable battery encapsulating structure is difficult to satisfy this a series of technology and safety requirements.
The utility model content
Can directly connect in groups with transient large current discharge and guarantee battery operated safety in order to solve battery; the utility model provides a kind of secure package mode; the internal protection plate is removed; change by the unified protection in back in groups; added the transducer of real-time monitor temperature at big current work; the battery output electrode is selected the slotting spring mode of reliable contact, has designed firm electrode fixed mount in battery case.
The technical scheme that its technical problem that solves the utility model adopts is: electrokinetic cell secure package structure is inserted spring, electrode fixed mount and battery case and is formed by rechargeable battery electricity core, temperature sensor, electrode, the independent respectively output of rechargeable battery electricity core electrode and temperature sensor electrode, not not altogether, the slotting spring electrode that has fastening pressure is adopted in the output of rechargeable battery electricity core electrode, electrode fixed mount and shell are one, fixedly secure plug-in and insert the spring electrode, shell interpolation spring electrode can't be moved on the plug direction.
The beneficial effects of the utility model are, can directly connect, and can transient large current discharge, realizing the electric core variations in temperature of monitoring by temperature sensor, simple in structure, reliable, safety are beneficial to standardization.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is battery structure figure of the present utility model.
Fig. 2 is an overall schematic of the present utility model.
1. rechargeable batteries electricity core among the figure, 2. temperature sensor, the 3. slotting spring of battery electrode, 4. slotting spring, 5. electrode fixed mount, 6. battery case of temperature sensor electrode.
Embodiment
In Fig. 1, rechargeable battery electricity core (1) is drawn two can insert firmly welding of spring (3) by the electrode and the battery electrode of instantaneous large-current, temperature sensor (2) is tightly adhered to electric core (1) central authorities and two electrodes and temperature sensor electrode is inserted firmly welding of spring (4), fixedly secure slotting spring electrode (3), (4) by electrode fixed mount (5), in order to guarantee that outer electrode plug strength can not cause that the internal electrode pine is disconnected when big, cover battery case (6) and use screw-driving, end product as shown in Figure 2.
Rechargeable battery electricity core (1) adopts lighium polymer 3Ah aluminum-plastic composite membrane to encapsulate electric core in the present embodiment, temperature sensor (2) adopts AT103 type thermistor, slotting spring is respectively 6.3mm and 2.8mm specification, can pass through the above instantaneous large-current of 60A, and shell adopts the hard plastics injection mo(u)lding.
A plurality of the utility model structure batteries can directly be connected in groups, and can unify or control protection respectively.
