The portion that connects is connected with battery core 10, and Plug Division 212 matches with connecting portion 213.Collector plate 21
Being connected in battery core 10 by fixed part 211, making can between collector plate 21 and battery core 10
Transmission electric energy；Plug Division 212 matches with connecting portion 213, enables the two to cooperate,
Concrete the most multiple collector plate 21 are sequentially connected, are positioned at the inserting of collector plate 21 of rear end
Connect in the connecting portion 213 of the collector plate 21 that portion 212 is plugged on front end so that multiple collector plate
21 are interconnected, and then multiple battery core 10 is connected.
Specifically, in some preferred embodiments, fixed part 211 is tabular, Plug Division
212 is U-shaped, and its inversion is connected to fixed part 211；Connecting portion 213 is fixed on fixed part 211
Sidepiece.As shown in Figure 4, flat fixed part 211 can conveniently be connected to battery core 10
On, U-shaped Plug Division 212 is inverted on fixed part 211 and defines ring-type chamber, connects
Portion 213 is positioned at the sidepiece of fixed part 211, the convenient Plug Division 212 with other collector plate 21
Match.
In collector plate 21, Plug Division 212 and connecting portion 213 match, and serve main
The effect of electric energy transmission, the concrete structure of connecting portion 213 can also be multiple, alternatively,
In some embodiments: connecting portion 213 includes the connecting plate 214 being connected with fixed part 211, should
The top of connecting plate 214 and bottom are equipped with elastic construction 215；The top of elastic construction 215
Higher than the inner roof wall of Plug Division 212 or concordant with the inner roof wall of Plug Division 212；Elastic construction
The bottom of 215 is less than the top of fixed part 211 or concordant with the top of fixed part 211.
Further referring to Fig. 4, connecting plate 214 is connected to the sidepiece of fixed part 211, for side
Just connecting portion 213 matches with Plug Division 212, connecting plate 214 include one section of slab construction and
One section of arcuate structure, connecting plate 214 is connected with fixed part 211 by its arcuate structure, makes to put down
Plate structure can be positioned at higher position, facilitates grafting；Set at connecting plate 214 top and bottom
The elastic construction 215 put, plays main interconnection function；As mentioned above, this chi
Very little elastic construction 215 makes connecting portion 213 can produce after being connected with Plug Division 212 necessarily
Elastic deformation, make connecting portion 213 and Plug Division 212 stably to connect so that two
Collector plate 21 can stably be connected.
Elastic construction 215 can be arranged on connecting portion 213, it is also possible to is arranged on Plug Division
212 is internal, can play its effect equally.
More specifically, Plug Division 212 is stretching structure, top and the bottom of connecting plate 214 are equal
It is provided with multiple elastic construction 215, the orientation of multiple elastic constructions 215 and Plug Division 212
Draw direction perpendicular.The elastic construction 215 of this structure, connect Plug Division 212 and
During connecting portion 213, the draw direction along Plug Division 212 inserts connecting plate 214 and elastic construction
215, now elastic construction 215 runs along its length direction, makes the connecting portion 213 can be square
Just Plug Division 212 is inserted, and sufficiently stable after the two is connected.
More specifically, elastic construction 215 is U-shape structure, elastic construction 215 and connecting plate
Ring-type buffer part 216 is formed between 214.When elastic construction 215 produces deformation upwards or to
Lower compression buffer part 216, makes connection more stable.
Battery core 10 is connected with collector plate 21, specifically, and the lug 101 end folding of battery core 10
Bending l-shaped, lug 101 is weldingly connected with the weld part of collector plate.Lug 101 structure
As shown in Figure 8；Further as it is shown in figure 1, the fixed part 211 of collector plate 21 is pressed in
Between lug 101 and battery core 10, this attachment structure is simple and convenient, by grafting relation i.e.
Can realize, it is not necessary to can be realized by complicated connector or Joining Technology.At dismounting collection
During stream plate 21, the opposite direction along grafting takes off collector plate 21.
In addition to above-mentioned parts, this soft-package battery module can also include miscellaneous part, such as, also
Include battery mounting 40 and side protection cap 50, multiple battery cores 10 be fixed on one or
In multiple battery mountings 40；Battery core 10 connection being positioned at both sides has side protection cap 50.
Battery mounting 40 plays protection and the effect of the parts such as fixing battery core 10 and collector plate, its knot
Structure is as shown in Figure 7.Side protection cap 50 plays protection battery core 10 and battery mounting from both sides
The effect of 40.Its structure can be as shown in fig. 1, it is also possible to is other structures.Specifically,
Weld part is weldingly connected with the lug 101 of battery core 10, fixed part 211 and battery mounting 40
Being fastened by bolts connected, the most multiple battery cores 10 arrange along its thickness direction,
Each battery core 10 is fixed in a battery mounting 40.Each battery mounting 40
