Cross-sectional area, bigger than the cross-sectional area that common rib 31 is located at the node 325 at the transverse rod strip 4, thereby, it is possible to increase bifurcated muscle
Mechanical strength of the item 32 at this prevents from producing fracture at this.
Preferably, the cross-sectional area of the vertical bar item 3 from the first side 11 of frame 1 to the second side of frame 1
It is gradually reduced at 12, vertical bar item is then thicker closer to the part of plate ear 2 as a result, the big electricity being better able near receiving plate ear 2
Stream improves corrosion resistance, reduces cross-sectional area in the part far from plate ear, can reduce lead loss.
Classify from cross-sectional area, which divides for first group of vertical bar item and second group of vertical bar item, and first group perpendicular
Rib and second group of vertical bar item separately include at least one vertical bar item.Relatively, any one in first group of vertical bar item is perpendicular
Rib being closer from plate ear 2, any one vertical bar item in second group of vertical bar item is larger with a distance from plate ear 2, enables
Average traversal of the average traversal area of any vertical bar item in one group of vertical bar item than any vertical bar item in second group of vertical bar item
Area is big, so that the vertical bar item closer to plate ear 2 is thicker, the high current being better able near receiving plate ear 2 improves corrosion resistance
Can, reduce cross-sectional area in the part far from plate ear, can reduce lead loss.First group of vertical bar item and second group of vertical bar item are included
The quantity of vertical bar item can be selected according to the specific structure of the size of plate ear 2, grid, in the present embodiment, from right to left
First to the 5th vertical bar article and the 12nd to the 22nd vertical bar article are first group of vertical bar article, the six roots of sensation to the
Ten vertical bar items are second group of vertical bar item.
In the present embodiment, the cross section of the transverse rod strip 4 and vertical bar item 3 is hexagon, and cross-sectional area can be by changing
The width of variable cross-section is realized.
Embodiment two
As shown in Figures 3 and 4, the present embodiment is basically the same as the first embodiment, and difference place is:
Node between the bifurcated section 322 of different bifurcated ribs 32 and latter end 323 is located on different transverse rod strips 4.It is preferred that
Ground, the node between the bifurcated section 322 and latter end 323 of bifurcated rib are alternately located on two adjacent transverse rod strips 4.Specifically,
Different according to 324 position of node between bifurcated section 322 and latter end 323, bifurcated rib is divided into first group of bifurcated rib 326 and
Two groups of bifurcated ribs 327, the node between the bifurcated section 322 and latter end 323 of first group of bifurcated rib 326 is located to be counted from top to bottom
Six roots of sensation transverse rod strip on, node between the bifurcated section 322 and latter end 323 of second group of bifurcated rib 327 is located at from top to bottom
On the 7th several transverse rod strips, first group of bifurcated rib 326 is alternately arranged with second group of bifurcated rib 327, common muscle in consideration
In the case where item 31, i.e. first group of bifurcated rib 326, common rib 31, second groups of bifurcated ribs 327, common ribs 31, so
Successively replace.This first group of bifurcated rib 326 is from the bifurcation site of second group of bifurcated rib 327 in different transverse rod strips 4
It is arranged alternately, about the 322 bifurcated section of bifurcated rib can be misplaced at position, so that the density layout of vertical bar item is more equal
Even, electric conductivity is more stable.
