Description
Technical field
This utility model belongs to field of photovoltaic technology, relates to a kind of polycrystalline cell piece.
Background technology
Polycrystalline cell piece includes main grid and secondary grid, as it is shown in figure 1, main grid includes several main parts 1, adjacent at two
Being provided with connecting portion 2 between main part 1, the quantity of the connecting portion 2 between two adjacent main parts 1 is one, connecting portion 2
It is in the center of two adjacent main parts 1, two adjacent main parts 1 are further fixed on welding 3, on the right side of welding 3
It is in the left side on the right side of main part 1, between i.e. two adjacent main parts 1, a breach 4 can be formed.Such welding is in welding
If when the amount of offsetting, there will be a lot of disconnected joint between main part, causing main grid less stable.
Summary of the invention
The purpose of this utility model is to there are the problems referred to above for existing technology, it is proposed that a kind of polycrystalline cell piece, should
The feature that the main grid of cell piece has good stability, flatness is high.
The purpose of this utility model can be realized by following technical proposal: polycrystalline cell piece, including main grid and secondary grid, main
Grid include several main parts, are provided with connecting portion between two adjacent main parts, it is characterised in that adjacent at two
Connecting portion quantity between main part is two, the most left connecting portion and right connecting portion, described left connecting portion be connected to two adjacent
Main part between, left connecting portion is the most concordant away from the side of right connecting portion and the wherein side of main part, and right connecting portion is remote
The most concordant with the wherein side of main part from the side of left connecting portion, main part is further fixed on welding, welding
Width is equal to or more than the width of main part.
Main part can be covered by welding, and therefore, in actual mechanical process, the width of welding is more than the width of main part
Degree, so makes main grid have more preferable stability.
Described left connecting portion width is identical with the width of right connecting portion.
The width of described main part is more than three times of left connecting portion width.
Described welding is fixed on two adjacent main parts by the way of welding.
Compared with prior art, this polycrystalline cell piece has the advantage that
1, the connecting portion quantity between two adjacent main parts is two, improves stability.
2, left connecting portion is the most concordant away from the side of right connecting portion and the wherein side of main part, and right connecting portion is away from a left side
The side of connecting portion is the most concordant with the wherein side of main part, and main part can be covered by welding, makes the smooth of main grid
Degree is better.
Accompanying drawing explanation
Fig. 1 is the main grid structural representation inside background technology.
Fig. 2 is main grid structural representation of the present utility model.
In figure, 1, main part；2, connecting portion；2a, left connecting portion；2b, right connecting portion；3, welding；4, breach.
Detailed description of the invention
The following is specific embodiment of the utility model and combine accompanying drawing, the technical solution of the utility model is made further
Description, but this utility model is not limited to these embodiments.
Polycrystalline cell piece is including main grid and secondary grid, as in figure 2 it is shown, main grid includes several main parts 1, adjacent at two
Main part 1 between be provided with connecting portion 2, it is characterised in that connecting portion 2 quantity between two adjacent main parts 1 is
Two, the most left connecting portion 2a and right connecting portion 2b, described left connecting portion 2a are connected between two adjacent main parts 1, Zuo Lian
Meeting portion 2a the most concordant away from the side of right connecting portion 2b and the wherein side of main part 1, right connecting portion 2b is away from left connecting portion
The side of 2a is the most concordant with the wherein side of main part 1, is further fixed on welding 3, the width of welding 3 on main part 1
Width equal to or more than main part 1.
Main part 1 can be covered by welding 3, and therefore, in actual mechanical process, the width of welding 3 is more than main part 1
Width, so makes main grid have more preferable stability.
Described welding 3 is fixed on two adjacent main parts 1 by the way of welding.
Described left connecting portion 2a width is identical with the width of right connecting portion 2b, and left connecting portion 2a width is 0.12mm.
The width of described main part 1 is more than three times of left connecting portion 2a width, and specifically, the width of main part 1 is
0.4mm。
Secondary grid in the present embodiment are prior aries, and its structure is not described in detail, the miscellaneous part of polycrystalline cell piece
It is the most all prior art, is not described in detail.
Specific embodiment described herein is only to this utility model spirit explanation for example.This utility model institute
Belong to those skilled in the art described specific embodiment to make various amendment or supplement or use similar
Mode substitute, but without departing from spirit of the present utility model or surmount scope defined in appended claims.
Although the most more employing 1, main part；2, connecting portion；2a, left connecting portion；2b, right connecting portion；3, welding；
4, the term such as breach, but it is not precluded from using the probability of other term.Use these terms to be only used to more easily to retouch
State and explain essence of the present utility model；Being construed as any additional restriction is all and this utility model spirit phase
Run counter to.
