A second card convex 320 is corresponding with second card slot 330.In addition, the first battery core insulating sheath 200, which may also comprise, is respectively arranged on
First card convex 220 (first card convex 220 is respectively provided on each side) on one lid, 210 two sides, and
First card slot 230 being respectively arranged on 210 two sides of the first lid (is respectively provided with one first card on each side
Slot 230), and the first card convex 220 on a side is corresponding with the first card slot 230 on another side.Moreover, the second electricity
Core insulation sheath 300 may also comprise 320 (i.e. each side of the second card convex being respectively arranged on 310 two sides of the second lid
Second card convex 320 is respectively provided on face), and second card slot 330 being respectively arranged on 310 two sides of the second lid
(second card slot 330 is respectively provided on each side), and the second card convex 320 and another side on a side
On the second card slot 330 it is corresponding.In this way, convenient for two the first battery core insulating sheaths 200 are buckled by two pairs of buckle structures
It connects, is also convenient for two the second battery core insulating sheaths 300 carrying out snapping by two pairs of buckle structures, connects simple and convenient and stablize
Reliably, and structure is simple.In this way, fixation simply and easily can be attached to two battery core units 10.
In addition, when the connection of the first battery core insulating sheath 200 of two battery core units 10, one of battery core unit 10
There is the first gap between first battery core insulating sheath 200 and the first battery core insulating sheath 200 of another battery core unit 10.I.e.
First gap can be set between two the first battery core insulating sheaths 200 interconnected, and first gap is set with lid
Gap connection between battery core 100 in two the first battery core insulating sheaths 200, it is logical convenient for two battery cores 100
(the first battery core insulating sheath 200 can be set to 100 top of battery core to the first gap at the top of crossing, so that the first gap digit
In 100 top of battery core) it radiates, the principle for making full use of thermal current to flow up, so that the heat dissipation to battery core
Better effect.
Moreover, in some embodiments, may make the first of 210 side of the first lid of the first battery core insulating sheath 200
The height value of card convex 220, greater than the depth of 210 the first card slot of the other side 230 of the first lid of the first battery core insulating sheath 200
Value.In this way, first battery core is exhausted when the first battery core insulating sheath 200 by two battery core units 10 may make to be attached
First card convex 220 of edge sheath 200 cannot fasten completely with the first card slot 230 of another the first battery core insulating sheath 200, and
So that the first card convex 220 being caught in the first card slot 230 is partially protrude through outside the first card slot 230, thus in two the first battery cores
The connection lateral position of insulating sheath 200 forms the first above-mentioned gap, is flowed convenient for air by first gap.
