Embodiment
Also by reference to the accompanying drawings the technical solution of the utility model is described in further detail below by specific embodiment.
Embodiment 1:
In the embodiment shown in fig. 1, a kind of small size lithium ion battery adapter plate structure, comprise keyset body 1, keyset body 1 comprises plate body 2 and pad 3, plate body 2 both sides respectively indentation are provided with some welding plate sheets 4, pad 3 is welded on welding plate sheet 4, and the room 7 of the corresponding opposite side of welding plate sheet 4 of plate body 2 side is arranged, and the welding plate sheet 4 of the corresponding opposite side in room 7 of side is arranged.
The welding plate sheet 4 plate face of plate body 2 corresponding to plate body two lateral body is provided with the conducting wire 5 of equal number.Conducting wire 5 is arranged in parallel, and the end of plate body 2 corresponds to every bar conducting wire 5 and is provided with contact 6.
Plate body 2 is rectangular plate, and the rectangular structure of each gullet plate structure plate 4 and plate body 2 are wholely set.Pad 3 is one side pad, and the size of pad 3 is less than the size of welding plate sheet 4.
This small size lithium ion battery adapter plate structure, is specially adapted to reduce production cost in lithium cell for electric bicycle production process.Use this keyset significantly can reduce keyset area cost, scolding tin cost and artificial threading cost.The competitiveness of Products can be improved in cost control and production efficiency.It is a kind of scheme that the battery pack of the multiple model of lithium battery PACK assembling process should adopt.
This small size lithium ion battery adapter plate structure, can reduce production cost, enhance productivity.This keyset profile is welding plate sheet 4, and the more traditional keyset area of pad 3 is much little, and linkage function does not but affect.The welding plate sheet 4 of plate body 2 both sides staggers setting mutually.This structure is also used in the splicing manufacture of polylith same keyset while of being applicable to the series connection of battery.The pad 3 of this keyset does not comprise the pad hole of cell polar ear cross-under, is the one side pad between traditional two lug eyelet welding dishes.Splice lithium battery keyset by adopting welding plate sheet 4 and use keyset area to reduce; The soldering tin amount used during by the size of this little pad to reduce soldering polar ear.By design welding plate sheet, this keyset has reached not to be needed to perform this procedure of cross-under lug; Reduce pad and reduce weld time.
The one side pcb board of tradition lithium battery keyset to be shape be rectangle, this small size lithium ion battery adapter plate structure is the one side pcb board of welding plate sheet, save a part for sawtooth and other one piece of pcb board splicing, make the original pcb board of limited areal can do traditional keyset quantity of about 1.5 times.What small size keyset adopted is small rectangular pad tin amount is almost 1/3 of original keyset pad, greatly reduces the cost using scolding tin.
This small size lithium ion battery adapter plate structure battery core traditional with my company is worn compared with lug (battery core both positive and negative polarity is through keyset), this keyset does not need to wear lug, decrease the operation of wearing lug, the amount of scolding tin is used to reduce, workman reduces weld time, increases safety in utilization and the useful life of battery.
In battery pack, this keyset can carry out connecting the effect connecing battery core series connection lug and fixing lug wherein, this keyset can fix cell polar ear effectively not to be affected the series connection link effect between lug simultaneously, his linking together completely still by this link of lug of battery core.
