The first positive connection terminal 32 and the first negative connection terminal 33 are both protrudingly disposed on the first electrical device body 31 along a first direction A, and the first positive connection terminal 32 and the first negative connection terminal 33 are stacked along a second direction B. The second positive connection terminal 42 and the second negative connection terminal 43 are both protrudingly disposed on the second electrical device body 41 along the first direction A, and the second positive connection terminal 42 and the second negative connection terminal 43 are stacked along a second direction B.

[0061] In one embodiment, referring to Figures 1 to 5As shown, the side of the first positive connection terminal 32 away from the first electrical device body 31 along the first direction A and the side of the second positive connection terminal 42 away from the second electrical device body 41 along the first direction A are partially overlapped and connected in the second direction B; the side of the first negative connection terminal 33 away from the first electrical device body 31 along the first direction A and the side of the second negative connection terminal 43 away from the second electrical device body 41 along the first direction A are partially overlapped and connected in the second direction B.

[0063] In this embodiment, the first positive electrode connection terminal 32 and the first negative electrode connection terminal 33 are both constructed as a connection sheet structure, and the second direction B mentioned above is the thickness direction of the first positive electrode connection sheet and the first negative electrode connection sheet. In addition, the projection of the first positive electrode connection sheet in the second direction B at least partially overlaps with the projection of the first negative electrode connection sheet in the second direction B. By stacking and arranging the first positive electrode connection sheet and the first negative electrode connection sheet of different polarities, the inductance loop formed can be greatly reduced, thereby reducing the generation of stray inductance. In addition, for the second positive electrode connection terminal 42 partially overlapping and connected with the first positive electrode connection sheet, the present disclosure does not limit the specific structure of the second positive electrode connection terminal 42, which can be sheet-shaped, rod-shaped, etc., and the present disclosure does not limit this. Similarly, the present disclosure does not limit the specific structure of the second negative electrode connection terminal 43.
[0064] In other embodiments, referring to Figures 1 to 5As shown, the second positive electrode connection terminal 42 includes a second positive electrode connection sheet, the second negative electrode connection terminal 43 includes a second negative electrode connection sheet, the second direction B is the thickness direction of the second positive electrode connection sheet and the second negative electrode connection sheet, and the projection of the second positive electrode connection sheet in the second direction B at least partially overlaps with the projection of the second negative electrode connection sheet in the second direction B; the first positive electrode connection sheet and the second positive electrode connection sheet are parallel to each other and staggered along the second direction B to partially overlap and connect; the first negative electrode connection sheet and the second negative electrode connection sheet are parallel to each other and staggered along the second direction B to partially overlap and connect. That is, in this embodiment, the first positive electrode connection terminal 32, the second positive electrode connection terminal 42, the first negative electrode connection terminal 33 and the second negative electrode connection terminal 43 are all configured as a connection sheet structure, which is thin and compact, and can also facilitate the stability of the overlapping connection.
[0065] Optionally, refer to Figure 4 and Figure 5 As shown, the overlapping area of the first positive electrode connecting sheet and the second positive electrode connecting sheet is configured as a first overlapping area 30, and the overlapping area of the first negative electrode connecting sheet and the second negative electrode connecting sheet is configured as a second overlapping area 40, and the first overlapping area 30 and the second overlapping area 40 are arranged at intervals in the first direction A. Avoid the problem of damage caused by the relative arrangement of the first overlapping area 30 and the second overlapping area 40 during the subsequent connection process. Optionally, the length of the first overlapping area 30 and / or the second overlapping area 40 in the first direction A is between 2 mm and 8 mm. However, the present disclosure does not limit the length.
[0066] Optionally, refer to Figure 4 and Figure 5 As shown, the first positive electrode connecting sheet and the second positive electrode connecting sheet are connected by melting, and the first melting regions of the first positive electrode connecting sheet and the second positive electrode connecting sheet are located in the first overlapping region 30, and the length of the first melting region in the first direction A is between 0.5 mm and 4 mm; and / or, the first negative electrode connecting sheet and the second negative electrode connecting sheet are connected by melting, and the second melting regions of the first negative electrode connecting sheet and the second negative electrode connecting sheet are located in the second overlapping region 40, and the length of the second melting region in the first direction A is between 0.5 mm and 4 mm.

The first melting area and the second melting area are also spaced apart along the first direction A to avoid high temperature generated at the two melting positions in the same area relative to each other and damage other structural parts.
[0068] Reference Figure 4 and Figure 5 As shown, the projections of the first positive electrode connecting sheet and the second positive electrode connecting sheet along the second direction B are configured as the first projection, the projections of the first negative electrode connecting sheet and the second negative electrode connecting sheet along the second direction B are configured as the second projection, and the length of the first projection in the first direction A is the same as the length of the second projection in the first direction A. The magnetic field generated by the current circuits of the first positive electrode connecting sheet and the second positive electrode connecting sheet and the magnetic field generated by the current circuits of the first negative electrode connecting sheet and the second negative electrode connecting sheet can offset each other, further reducing the generation of stray inductance.
[0069] Optionally, refer to Figures 6 to 8 As shown, the length of the first positive electrode connecting sheet along the third direction C is the same as the length of the first negative electrode connecting sheet along the third direction C, wherein the first direction A, the second direction B, and the third direction C are perpendicular to each other. By making the length of the first positive electrode connecting sheet along the third direction C the same as the length of the first negative electrode connecting sheet along the third direction C, the stacking correspondence of the first positive electrode connecting sheet and the first negative electrode connecting sheet can be ensured in the third direction C, thereby further reducing the generation of stray inductance.
[0070] Optionally, refer to Figures 9 to 11 As shown, the length of the second positive electrode connecting sheet along the third direction C is the same as the length of the second negative electrode connecting sheet along the third direction C, wherein the first direction A, the second direction B, and the third direction C are perpendicular to each other. By making the length of the second positive electrode connecting sheet along the third direction C the same as the length of the second negative electrode connecting sheet along the third direction C, the stacking correspondence of the second positive electrode connecting sheet and the second negative electrode connecting sheet can be ensured in the third direction C, thereby further reducing the generation of stray inductance.

That is, the first melting area of the first positive connection sheet and the second positive connection sheet and the second melting area of the first negative connection sheet and the second negative connection sheet are both opposite to the overlapping area of the first insulating portion 34 and the second insulating portion 44, which can effectively enhance the creepage distance and further improve the insulation performance; on the other hand, the overlapping first insulating portion 34 and the second insulating portion 44 can effectively withstand the high temperature generated by the melting area, avoiding damage to the first insulating portion 34 and the second insulating portion 44 and causing insulation failure.

In this embodiment, the bending arrangement of the first insulating portion 34 and the second insulating portion 44 can ensure that the two can overlap.
[0074] The first insulating portion 34 may include at least one first insulating layer, and the second insulating portion 44 may include at least one second insulating layer.

In addition, the first insulating layer and the second insulating layer may be made of a flexible material, which is easy to bend and bend without damage, and is easy to overlap the first insulating layer and the second insulating layer.

The length of each second positive connection terminal 42 along the third direction C can be equal to the length of the corresponding second negative connection terminal 43 along the third direction C, so as to ensure the overlapping arrangement of the second positive connection terminal 42 and the second negative connection terminal 43 in the third direction C, and further reduce the generation of stray inductance.
