Embodiment

Below in conjunction with specific embodiment and the right technical scheme of accompanying drawing, be described in detail, so that it is clearer.Following examples are only in order to describe the cited comparatively detailed embodiment of the utility model, as what the utility model was not protected, do not draw in the net grid structure and draw in the net the restriction of grid arrangement structure.

The upper and lower, left and right that adopt in specific embodiment of the utility model are for convenience of description, and conduct is not to restriction of the present utility model.

Fig. 1 a is traditional grid structure schematic diagram that draws in the net; Fig. 1 b is traditional grid arrangement structural representation that draws in the net; Fig. 2 a is the grid structure schematic diagram that draws in the net of the present utility model; Fig. 2 b be new construction of the present utility model draw in the net grid arrangement structural representation.

As shown in Fig. 1 a and Fig. 1 b, traditional grid structure and draw in the net grid arrangement structure of drawing in the net, in Fig. 1 a and Fig. 1 b, draw in the net grid structure, comprise that rib node 130, upper side frame 140, lug 150 and the roller shear of lower frame 110, netted rib 120, netted rib 120 divides tangent line 160.After being cut by coated plate roller shear, minute point of contact is on netted rib 120, causing drawing in the net minute point of contact of the grid left and right sides is the breakpoint of netted rib 120 independently, this structure is subject to slight External Force Acting (as colliding with in pole plate transportation) and both may have caused perk to form burr, has greatly increased that storage battery burr in assembling and use procedure pierces through dividing plate and the risk that causes battery short circuit to lose efficacy.The left and right sides is Fig. 1 a and the relative beholder's of Fig. 1 b description.

As shown in Figure 2 a, a kind of grid structure that draws in the net, the rib node 230, upper side frame 240 and the lug 250 that comprise lower frame 210, netted rib 220, netted rib 220, this upper side frame 240 and lower frame 210 are oppositely arranged, the rib node 230 of netted rib 220 and netted rib 220 is between upper side frame 240 and lower frame 210, lug 250 is located on upper side frame 240, and minute point of contact of dual-side of grid structure of drawing in the net that roller shear is cut formation is on the rib node 230 of netted rib 220.Wherein, minute point of contact is the point that two netted ribs 220 cross and form.
