Description
Technical field
The utility model relates to a kind of storage battery, especially relates to a kind of storage battery be combined into by the monomer battery core, belongs to electrical power storage equipment manufacturing technology field.
Background technology
Lithium-ions battery battery core traditional connected mode in parallel, series connection adopts pole, brace etc. to be connected usually.This connection, easily occur that the aluminum plastic film that cell polar ear presses down battery core self produces damage, negative electrode lug particularly, usually adopt nickel sheet or nickel plating copper sheet, material is harder, with the aluminum plastic film EDGE CONTACT or puncture aluminum plastic film, makes battery core the phenomenons such as short circuit, flatulence occur, further the performance and used life of assembled battery exerted an influence, even cause security incident.Because flow process is complicated, troublesome poeration, increased operator's labour intensity, the hidden danger of quality that also exists nut loosening to produce simultaneously.Adopt the cost of traditional battery core series, parallel mode higher.
The utility model content
Technical problem to be solved in the utility model is: a kind of storage battery be combined into by the monomer battery core that the aluminum plastic film of battery core is caused to damage that presses down that can effectively avoid positive and negative lug in the use procedure of storage battery is provided.
For solving the problems of the technologies described above adopted technical scheme, be: a kind of storage battery be combined into by the monomer battery core, comprise that at least three tops are respectively arranged with the monomer battery core of anode ear and negative electrode lug, described each monomer battery core is sequentially fixing, the anode ear of each the monomer battery core in the middle of being positioned at is connected with anode ear with the negative electrode lug of the monomer battery core adjacent with front and back respectively of negative electrode lug order, also comprise the fixed head that is provided with bar hole on connecting bolt and its, described fixed head is positioned at the top of fixing described each monomer battery core of order, the anode ear of leading mutually two described monomer battery cores and negative electrode lug are corresponding respectively to be connected by described connecting bolt after passing from described bar hole again.
Be further, also be furnished with hold-down nut between adjacent two bar holes of described fixed head, end at described anode ear and negative electrode lug is respectively arranged with connecting hole, described connecting bolt is screwed on described hold-down nut through after described connecting hole, and the anode ear of adjacent described monomer battery core and negative electrode lug are connected as one.
Further, described hold-down nut embeds in described fixed head.
Further, described fixed head is made by high-wear-resistance and flame-retardant unsaturated polyester glass fibre enhancement mode plastics or high-wear-resistance and flame-retardant PV plastics.
The beneficial effects of the utility model are: because the top layout in the fixing monomer battery core of order has described fixed head, and make described anode ear and negative electrode lug through after the bar hole on described fixed head, by connecting bolt, be communicated with, thereby make described anode ear install and all can directly not contact with the aluminum plastic film of each monomer battery core in use procedure with negative electrode lug, and then can effectively avoid the storage battery that formed by described monomer battery core in use, because cell polar ear presses down the damage that the battery core aluminum plastic film is produced caused.
