Embodiment
The present invention is described in further detail below by specific embodiment.
Fig. 3 is the partial schematic diagram in the first row negative electrode overlap joint zone.The first row negative electrode 24 is connected with lead-in wire, and lead-in wire 25 comprises clinch 251, extension 252, connecting portion 253.Clinch 251 is connected with 24 stacks of the first row negative electrode, is called overlap joint again.Clinch 251 bottoms extend to form extension 252 downwards, promptly, the clinch lower limb is connected with the extension top edge, and extension 252 is the shape of a similar right-angled triangle, and two right-angle sides of similar right-angled triangle are connected with connecting portion 253 top edges with the lower limb of clinch 251 respectively.Connecting portion 253 is connected to IC zone (not shown).
The comparison diagram of Fig. 4 after for the stack of the present invention's first line lead 25 and first line lead 15 of prior art design, first line lead of prior art is 15, it comprises clinch 151, connecting portion 152, the left side edge of clinch 151 is connected with connecting portion 152.As shown in Figure 4, the clinch 251 of lead-in wire 25 and the clinch 151 of lead-in wire 15 coincide, and overlapping the zone is Fig. 4 dot-hatched part, and this part area is identical.Clinch 151 is drawn with connecting portion 152 from left side edge and is connected, and connecting portion 152 connects IC zone (not shown) downwards.Among the present invention, the clinch 251 of first line lead connects extension 252 and connecting portion 253 downwards, and connecting portion 253 connects IC zone (not shown) downwards.Clinch extends to form connecting portion downwards, connecting portion bending once formation extension; And in the scheme of prior art, clinch bends downwards left, bends downwards to the right, bends downwards to the right after the extension downwards then again, has passed through to bend for 3 times just to reach the required angle in regulation connection IC zone.
Existing design is at Width, taken a regional X, the width of zone X is a width that lead-in wire takies at vertical direction, and need 2 bendings of connecting portion to connect the IC zone downwards at least, the present invention is by setting up extension 252, connecting portion 253 does not need bending and directly connects the IC zone, and does not have occupied area X, has saved the space on Width.
Another embodiment of the invention, different with a last execution mode is, and extension 252 parts of a last execution mode are connected with connecting portion 253, and in the present embodiment, extension 252 is connected with connecting portion 253 fully.Pin configuration is local as Fig. 5, clinch 351 lower limbs are connected with extension 352 top edges, extension 352 is similar right-angled triangle, and wherein two of similar right-angled triangle right-angle sides are connected with extension 352 with clinch 351 respectively, and connecting portion 353 width narrow down gradually.
