Abstract

The utility model discloses a bus bar outlet structure for a solar cell module which comprises interconnected belts, a cell matrix, a conjunction box, and a plurality of bus bars connecting the interconnected belts. The cell matrix is formed by cell sheets connected in series through the interconnected belts. Two sides of the cell matrix are respectively laminated by glass and a back board. EVA adhesive films are provided between the back board and the cell matrix and between the cell matrix and the glass. The conjunction box is installed on the center of the back board. Gaps are provided between the adjacent bus bars, and the bus bars are led out from two sides of the glass to the center of the glass in a parallel manner, are vertically and downward bended in the position corresponding to a wiring hole position of the conjunction box, and then penetrate through the back board and are inserted into the wiring hole. According to the utility model, the bus bars do not overlap with each other, and therefore do not need insulated pad bars, the production cost and manufacture hours are reduced, qualified rate of the products is greatly improved, the improved technology is simple, and the bus bar outlet structure for the solar cell module is suitable for mass production.

Description

The busbar outlet structure of solar module

Technical field

The utility model relates to a kind of busbar outlet structure of solar module, belongs to the photovoltaic technology field.

Background technology

At present, solar cell power generation can not discharge carbon dioxide or produce the gas harmful to greenhouse effect, and also noiselessness is a kind of net energy source, with environment good compatibility is arranged.Solar components is a kind of building material that integrates generating, sound insulation, heat insulation, safety, decoration functions, has demonstrated fully the intellectuality and the human features of building.Usually will they be separated avoiding overlapping short circuit with the insulation filler strip between the busbar of the solar module under the prior art, but the filler strip that insulate can come off usually easily, thereby make the overlapping and short circuit of busbar.

Summary of the invention

The purpose of the utility model is the defective that overcomes prior art, and the busbar outlet structure that need not isolate the solar module of avoiding short circuit phenomenon between a kind of busbar is provided.

The technical scheme that realizes the utility model purpose is: a kind of busbar outlet structure of solar module; It comprises interconnection band, battery matrix, terminal box and the some busbars that are connected the interconnection band; The battery matrix is made up of through interconnection band series connected battery sheet some row; There are glass and backboard in the two sides of battery matrix lamination respectively; Be provided with the EVA glued membrane between backboard and the battery matrix and between battery matrix and the glass, terminal box is installed in the center of backboard, has the gap between the adjacent busbar; And busbar is parallel shape draws from the center of two side direction glass of glass, and with corresponding position, the wiring hole position bending vertically downward of terminal box after pass backboard and insert wiring hole.

After having adopted technique scheme, all be gapped between the adjacent busbar of the utility model, and bending also have the gap between the busbar of terminal box; Busbar just can juxtaposition like this; Thereby just need not insulate filler strip, when having reduced production cost and worker, and improve the qualification rate of product greatly; It is also simple to improve technology, is fit to produce in enormous quantities.

Fig. 3 is the enlarged diagram in the busbar knee of Fig. 1.

Embodiment

For the content that makes the utility model is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, the utility model is done further detailed explanation,

Shown in Fig. 1 ~ 3; A kind of busbar outlet structure of solar module; It comprises interconnection with 3, battery matrix 4, terminal box 6 with is connected the some busbars 2 that interconnect with 3; Battery matrix 4 is with 3 series connected battery sheets to be made up of some row through interconnection, and there are glass 5 and backboard 7 in the two sides of battery matrix 4 lamination respectively, is provided with the EVA glued membrane between backboard 7 and the battery matrix 4 and between battery matrix 4 and the glass 5; Terminal box 6 is installed in the center of backboard 7; Have the gap between the adjacent busbar 2, and busbar 2 is parallel shape and draws from the center of two side direction glass 5 of glass 5, and with corresponding position, the wiring hole position bending vertically downward of terminal box 6 after pass backboard 7 and insert wiring holes.

EVA refers to vinyl-vinyl acetate copolymer.

All be gapped between the adjacent busbar 2 of the utility model; And crooked also have the gap between the busbar 2 of terminal box 6, and busbar 2 just can not juxtaposition like this, thereby just need not insulate filler strip; When having reduced production cost and worker; And improved the qualification rate of product greatly, it is also simple to improve technology, is fit to produce in enormous quantities.

Above-described specific embodiment; Purpose, technical scheme and beneficial effect to the utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of the utility model; Be not limited to the utility model; All within the spirit and principle of the utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection range of the utility model.
