Specific implementation mode
As shown in Figure 1, 2, the electric connection structure of no module state battery core 1 includes anode switching copper bar 2 and cathode switching copper
Row 5, anode switching copper bar 2 and cathode switching copper bar 5 are strip sheet metal, and 2 one end of anode switching copper bar is welded on anode electrode
On, the other end is equipped with the self-clinching stud 4 outwardly protruded, and 5 one end of cathode switching copper bar is welded on negative electrode, and the other end is set
There is a mounting hole, self-clinching stud 4 and mounting hole are matched structure, and when connection, self-clinching stud 4 passes through mounting hole, and passes through method
Blue face nut 3 is fixed.
Anode switching copper bar 2 and cathode switching copper bar 5 are both preferably z shape structures, i.e., anode switching copper bar 2 and cathode turn
The face equipped with 4/ mounting hole of self-clinching stud will be less than by connecing the welding surface of copper bar 5, so that anode switching copper bar 2 and cathode switching
When copper bar 5 connects, the face of self-clinching stud 4 and mounting hole reliably stacks, and flange nut is facilitated to fix.
As shown in figure 3, battery pack by simple frock clamp by two different connecting copper bars according to different directions
It is welded in battery core 1, then combines according to the sequencing battery core 1 that welding copper bus is completed that will transfer, while making cathode copper
Hole on row passes through self-clinching standoff on positive copper bar, is then locked with nut, a series of subsequent battery cores 1 are all in accordance with such
Mode then constitutes the battery pack of the electric connection structure assembly using no module state battery core 1.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the utility model implements not by above-mentioned
The limitation of mode, if the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is used, or not
It is improved by the present invention design and technical solution directly apply to other occasions, the scope of protection of the utility model it
It is interior.
