Reason content may include the detecting of voltage, the detection of temperature and voltage back etc..
In addition, referring to Figure 19 to Figure 20, respectively the connector 2 that confluxes includes the electricity of an electrode connecting parts 21, one
Road plate connector 22 and a bridgeware 23.The bridgeware 23 connects the connecting part of circuit board 22 with welding manner
Fixed part 221 and the electrode connecting parts 21 lattice 212.In the present embodiment, the circuit board connects
Part 22 is copper-based metallic material, and the electrode connecting parts 21 are a MULTILAYER COMPOSITE aluminium flake, and the bridgeware 23 is
One piece of aluminium (or solid aluminum), because the structure and material of the MULTILAYER COMPOSITE aluminium flake of the electrode connecting parts 21 are softer
And it is temperature sensitive, when being intended to the connecting part of circuit board 22 different from material and directly welding can it is more difficult and
Cost is higher, but by the material identical elder generation of bridgeware 23 with after the electrode connecting parts 21 welding, being somebody's turn to do
Connecting part of circuit board 22 is welded in the bridgeware 23 again, makes the electrode connecting parts 21, the connecting part of circuit board
22 are readily attached together with the bridgeware 23, and can use can be used for a large amount of productions and cost is relatively low
Ultrasonic welding or laser welding etc. welding means.Collocation refers to Figure 23, consequently, it is possible to work as the circuit
When the fixed part 221 of plate connector 22 is inserted in corresponding fixing groove 12, the connector 2 that confluxes can be made solid
It is placed in due to the Insulating frame 1 and the electrode connecting parts 21 in the storage tank 11.Shown in Figure 21, Figure 22
The connector 2 that confluxes structure with roughly the same shown in Figure 19, Figure 20, however, lattice 212 and
Joint-cutting 214 it is in opposite direction.
In addition, referring to Figure 16, Figure 24 and Figure 25, two above outermost two battery 20 are defeated
Go out in the embodiment of electrode piece 5, the material of the electrode connecting parts 51 and the connecting part of circuit board 52 is all
For copper, and the material of the weld pad 517 is aluminium and shape is rectangular, therefore the electrode connecting portion 511 passes through this
Weld pad 517 is welded in the electrode 201 of outermost battery 20, so can overcome different-metal material welding fusing point not
The problem of together and being difficult to implement welding.Furthermore the weld part 523 of the connecting part of circuit board 52 is directly to weld
In the electrode connecting portion 511.
In the present embodiment, refering to Figure 26, Figure 27 and Figure 28, it is accommodating that the sensor component 4 also includes one
Part 43, the accommodating part 43 are arranged at the electrode connecting parts 21 of the connector 2 that confluxes by means such as welding
Lattice 212, accommodating part 43 and formed with an accommodating hole 431 for housing the sensor 41, sensor
41 can be fixed in accommodating hole 431 by means such as heat-conducting glue, stickers.Certain lattice 212 also may be used
Directly crimp and form one and interior accommodating hole is placed in for the sensor 41, without the accommodating part 43
Construction, so also can reach the purpose that the sensor 41 is arranged to the connector 2 that confluxes.
In summary, respectively connector 2 that confluxes of battery connection module 10 of the present invention is connected by circuit board
In the corresponding conductive through holes 31 for being configured to be crimped on circuit board 3 of the crimping pin 222 of part 22, respectively should it make
Conflux connector 2 and the circuit board 3 can direct-assembling and being formed electrically connect, without what is welded
It step, can so simplify processing procedure, and avoid the risk of the component wear caused by welding process.Furthermore
The lattice 212 of electrode connecting parts 21 passes through the breeze way of joint-cutting 214 and second with two electrode connecting portion 211
215 separate structure, can be greatly reduced the lattice 212 and the circuit board being connected on lattice 212
Connector 22 and sensor 41 are because of the suffered influence of the displacement of two electrode connecting portion 211, deformation.Separately
Outside, the design for the crimping pin 422 that the sensor component 4 passes through the respectively conducting wire adapter 42, makes the sensor
41 can need not be electrically connected by way of welding with the circuit board 3 formation, and can be transferred by wire
Part 42 is crimped onto circuit board 3 together with the connector 2 that confluxes, and helps to simplify processing procedure.Importantly, by
There is the metallic combination of different materials, energy in the connector 2 that confluxes of the first embodiment and the second embodiment
The electrical connection of the electrode welding and circuit board 3 of battery 20 is more prone to corresponding to enough making, and can also increase solid
Use and electric conductivity are set for, therefore the purpose of the present invention can be reached really.
But as described above, only embodiments of the invention are of the invention real when that can not be limited with this
The scope applied, it is every made according to the present patent application claims and sharp description it is simple equivalent
Change and modification, are all still remained within the scope of the patent.
