Technical field
The utility model relates to space power system technical field, is specifically related to a kind of solar battery array long-life sheet of interconnect for space.
Background technology
Sheet of interconnect is on solar panel, to realize the electric component of solar cell series connection, and Fig. 1 is solar battery array solar cell series connection schematic diagram for existing space.The first solar cell 2 that is positioned at substrate 3 surfaces is connected by solar battery array sheet of interconnect 1 with the second solar cell.As shown in Figures 2 and 3, existing solar battery array sheet of interconnect 1 mainly adopted half " ring " that raise up as sheet of interconnect subtract stress structure 5, sheet of interconnect 1 two ends are passed through respectively welding pin 4 and are connected with bottom electrode with the top electrode of two solar cells.
This structure can reduce the active force of sheet of interconnect to solar cell solder joint in the high and low temperature environment of space, but be limited to space and the requirement of solar battery array flatness in vertical plane, this size that subtracts stress structure is restricted, structural stress is larger, have the risk of fatigue failure, the life-span can not meet the demand of long-life solar battery array.
In space, solar battery array is faced with complicated space environment, wherein the temperature difference is greater than the high and low temperature environment of 100 ℃ and can in solar battery array and sheet of interconnect, produces thermal stress, subtract stress loop structure and by the flexural deformation of self structure, reduce the thermal stress that is subject to of sheet of interconnect solder joint, and subtract stress loop, in high and low temperature environment, constantly stretch, shrink circulation and may cause subtracting stress loop fatigue failure.Sheet of interconnect, as the interconnection element on solar panel, is restricting the life-span of solar panel.
Utility model content
The problem that the utility model solves is the problem that in the space high and low temperature environment existing in existing sheet of interconnect, stress is large, the life-span is short; For solving described problem, the utility model provides a kind of solar cell for space use battle array sheet of interconnect.The space that the utility model provides solar battery array sheet of interconnect, comprising: subtract stress structure and welding pin, the described stress structure that subtracts is two arc stress structures that subtract of connecting at back.
Further, described two arc stress structures that subtract are connected in center, arc back.
Further, described two arc stress structures that subtract are about sheet of interconnect Central Symmetry.
Further, the described arc stress structure outer end that subtracts is tangentially extended and is connected with welding pin.

Embodiment
Hereinafter, in conjunction with the accompanying drawings and embodiments the utility model is further elaborated.
With reference to figure 4, the space that the utility model provides solar battery array sheet of interconnect, comprising: subtract stress structure 6 and welding pin, the described stress structure 6 that subtracts is two arc stress structures that subtract of connecting at back.Described two arc stress structures that subtract, in the series connection of center, arc back, form about the centrosymmetric structure of sheet of interconnect.
With reference to figure 4, the described arc stress structure that subtracts consists of the circular arc of multistage deep camber, tangent formation rounding off between circular arc.In the preferred embodiment of utility model, described arc diameter is between 0.8 ~ 4mm, and width is not less than 0.8mm.Described space can, by method machine-shapings such as punching press, cuttings, due to solar cell thickness, form the ladder of " Z " shape shown in Fig. 5 after assembling by solar battery array sheet of interconnect in sheet of interconnect 7 sides.Described subtracts stress structure design in horizontal plane, therefore the size restrictions that subtracts stress structure is less, can make full use of arc deep camber structure, reduces the rigidity of structure, thereby realization reduces stress, increases long-life object, can be optimized by increasing curvature.And that traditional " in vertical plane " sheet of interconnect structure is subject to spatial limitation is large.
Above-mentioned long-life sheet of interconnect has adopted two about the centrosymmetric arc stress structure that subtracts of sheet of interconnect, these two structures are connected mutually, in high and low temperature environment, can effectively reduce the single strain that subtracts stress structure, thereby further reduced the structural stress of sheet of interconnect, improved the life-span of sheet of interconnect.
In sum, the related space of the utility model is the stress structure that subtracts by two identical bow-shaped structural sheet of interconnect in series by solar battery array long-life sheet of interconnect, this structure can be utilized the space in plane, increase as much as possible the curvature of structure, thereby reduce the rigidity of structure, and the electric connection of solar cell is not had to negative effect, can effectively reduce structural stress, thereby improve the life-span of sheet of interconnect.
