The advantages that small volume, security are good, cycle life is good, green, moved in mobile electron electrical equipment, electric tool, electronic traffic
Power power supply etc. has broad application prospects.
Traditional lithium battery group production uses nickel strap spot welding assembling mode, and which operating efficiency is low, and cost of labor is high, exists
Potential safety hazard, the health that metal dust damages operating personnel is easily produced, and product structure is not enough securely.
Utility model content
In view of the shortcomings of the prior art, the utility model proposes a kind of cylindrical lithium battery group, it uses elastic press type and grafting
Formula connection instead of nickel strap spot welding connection, and whole production process only has assembly, be a kind of energy-conserving and environment-protective, efficiently low without welding
The mode of production of cost.
To achieve the above object, the utility model adopts the following technical scheme that：
A kind of cylindrical lithium battery group, formed by several groundwork module assembleds；The groundwork module is provided with
Some cylindrical lithium battery groove positions；Some metal contact chips, the contact chip are set respectively above and below the lithium battery groove position
Including the spring clip of left and right two, and the insert-connecting plate between two spring clips, two spring clips are located at adjacent cell groove position respectively
It is interior；Since the battery case position most on side, stagger battery case position of upper and lower contact chip is set, i.e. a left side for overlying contact piece is suppressed
The right spring clip of piece and lower contact piece is located in same battery case position；The most left and most right battery case position of groundwork module
Total positive electrode current exit, total cathodal current exit are inside set respectively, with draw respectively total positive pole of groundwork module and
The electric current of total negative pole；Grafting film perforation is set in the groundwork module, is connected for grafting between adjacent groundwork module；
The insert-connecting plate of the adjacent groundwork module is bonded in grafting film perforation, to connect the circuit between basic operational module.
Further, screw or thimble are set in the spliced eye, to compress two insert-connecting plates, make insert-connecting plate indirectly
Touch good.
Further, fixed between the groundwork module by bolt and nut, two kinds are set in groundwork module
Bolt hole, a kind of to connect two neighboring groundwork module, another kind is to the whole battery pack that is connected.
Further, total positive electrode current exit, total cathodal current exit set conducting metal screw respectively, use
To draw the electric current of total positive pole of groundwork module and total negative pole respectively.
Further, the upper and lower side of the groundwork module sets through hole respectively, with saving material.
The beneficial effects of the utility model are：All circuit connections use elastic press type and socket connection, possess
Quickly assemble, maintain easily the characteristics of maintenance, operating efficiency is high, and cost of labor is low, the firm safety of product structure.Also, compare
More traditional lithium battery group production, elastic press type instead of nickel strap spot welding with socket connection and connect, and whole production process is only spelled
Dress, it is a kind of energy-conserving and environment-protective, the mode of production of high efficiency, low cost without welding.
