In addition, the protector is a soft connector with high plasticity, is convenient to assemble with the wiring component, and has the advantages of simple structure, reasonable structure and low manufacture cost.
Description
Technical field
The utility model relates to field of batteries, particularly a kind of battery with overcurrent protection.
Background technology
The patent that China Patent Publication No. is CN102208696A " a kind of high-capacity lithium battery bag " discloses a kind of high-capacity lithium battery bag on October 5th, 2011; there is the lithium battery group be in series by several monomer battery cores; the charging inlet formed by female plug and male plug and electric discharge interface; also there is battery protecting plate; for the lithium battery group being overcharged, crossing, put, overcurrent protection and battery core electric voltage equalization, and electric weight display lamp, charging fuse, temperature control charge switch and electric discharge fuse.It is said; this lithium battery bag adopts the high-capacity lithium battery group; thereby there is little, lightweight, the light portable of volume, Gao Rong electricity, high-energy-density, high efficiency, high bearing capacity, have extended cycle life, the advantages such as self-discharge rate is low, memory-less effect, pollution-free and excellent constant pressure source performance; pass through battery protecting plate; effectively prevented from overcharging, cross put, the generation of the unfavorable conditions such as overcurrent, monomer battery core overtension; significantly improved lithium battery bag quality, had advantages of that stable performance, life-span are long.
But; its overcurrent protection mainly only depends on charging fuse and the electric discharge fuse on the battery protecting plate protective circuit; if, during the accidents such as lithium battery bag output is short-circuited, the protective circuit on battery protecting plate can't be protected, and have certain potential safety hazard.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of battery with overcurrent protection.
The utility model solves the technical scheme that its technical problem adopts:
A kind of battery with overcurrent protection, comprise battery module, and the output of described battery module is provided with lug, and described lug is connected with connecting part, and described lug is connected with connecting part by overcurrent fuse protection part.
For overcurrent fuse protection part being connected and using more conveniently, the shape of described overcurrent fuse protection part is designed to strip or band shape.
The beneficial effects of the utility model are: this battery arranges overcurrent fuse protection part by the output at battery module; when the lug of positive and negative electrode is short-circuited; overcurrent fuse protection part can fuse automatically, and when the battery protecting plate protective circuit lost efficacy, overcurrent fuse protection part serves as the backup protection measure; effectively avoid the generation of accident; in addition, overcurrent fuse protection part is Software Connector, and plasticity is strong; be convenient to and connecting part assembling, there is simplicity of design, rational in infrastructure, cost of manufacture is low.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is stereogram of the present utility model;
Fig. 2 is the enlarged drawing of the utility model a-quadrant.
Embodiment
With reference to Fig. 1, Fig. 2.A kind of battery with overcurrent protection, comprise battery module 1, and the output of described battery module 1 is provided with lug 2, and described lug 2 is connected with connecting part 3, and described lug 2 is connected with connecting part 3 by overcurrent fuse protection part 4.
In the present embodiment, battery module 1 is formed in parallel by 5 groups of several battery cores, and the lug 2 of battery core 5 positive and negative electrodes of every group is in parallel respectively, then is electrically connected to connecting part 3 by overcurrent fuse protection part 4.More specifically, be provided with the pole (not marking in figure) of positive and negative electrode on this connecting part 3, the lug 2 of positive and negative electrode is electrically connected to the terminals of positive and negative electrode pole respectively by overcurrent fuse protection part 4.
During real work, the blowout current of overcurrent fuse protection part 4 is 150%～200% of battery module 1 operating current.This blowout current generally can be avoided the false triggering of overcurrent fuse function higher than the protective current of battery protecting plate protective circuit, reduces maintenance cost.
In order to make to connect and to use more conveniently, the shape of described overcurrent fuse protection part 4 is designed to strip or band shape, and the embodiment in Fig. 1 adopts banded overcurrent fuse protection part 4.Overcurrent fuse protection part 4 materials adopt flexible metal materials to be advisable, and to improve the plasticity of overcurrent fuse protection part 4, are convenient to the assembling of battery module 1 and connecting part 3, contribute to simplify assembly difficulty, improve packaging efficiency.
Overcurrent fuse protection part 4 generally can adopt punching press or excision forming, is convenient to processing.The two ends of overcurrent fuse protection part 4 are connected on lug 2 and connecting part 3 by supersonic welding respectively.Overcurrent fuse protection part 4 is not limited only to ultrasonic bonding with the connected mode of lug 2 and connecting part 3, also can adopt riveted joint, screw connection, socket, clamping etc.And battery module 1 can also adopt the frame mode of monomer battery core, or adopt the frame mode be in series by some groups of battery cores 5; If adopt the latter, overcurrent fuse protection part 4 also can be connected between the lug of battery core 5 mutual positive and negative electrodes of connecting.Abovely for those skilled in the art, all can clearly understand, repeat no longer one by one.
According to above-mentioned principle, the utility model can also carry out suitable change and modification to above-mentioned execution mode.Therefore, the utility model is not limited to the embodiment of above-mentioned announcement and description, to simple modification of the present utility model and change, also should fall in the protection range of the utility model claim.Although used some specific terms in this specification, these terms just for convenience of description, do not form any restriction to the utility model.
