Chip diode, although achieve diode built-in with photovoltaic module inside, but need when diode damages and needs to change
Open whole backboard or glass plate is replaced, assembly can be damaged, be difficult to operation.
Utility model content
The purpose of this utility model is to provide a kind of diode to be built in assembly, and is easily changed after diode damages
Solar components.
To this end, this utility model adopts the following technical scheme that
The photovoltaic module of a kind of diode-built-in, including front glass panel, solaode chip arrays, backboard be arranged on the back of the body
Line box on plate, solaode chip arrays includes some solaode strings being connected in series, it is characterised in that need bypass
Two string battery strings between connect have diode；One section of busbar, and its is welded the most in advance on the both positive and negative polarity of described diode
In one pole need draw be connected with line box weld longer busbar the most in advance；During component stack, will weld in advance
The diode of busbar is connected to by polarity to need between two string battery strings of bypass；Weld longer busbar in advance
One end, then turn up outside extraction assembly, for being attached with line box positive/negative by this section of bus bar grown；At diode
One perforate is set at the backboard of correspondence position；The busbar drawn after turning up on described diode is derived from tapping；Described line
Box is arranged in perforate, is used for sealing perforate.
Further, the busbar same material that the busbar on the both positive and negative polarity of described diode uses with photovoltaic module.
Further, described line box is provided with turns up the busbar pad that is connected of end with busbar.
Further, described backboard has perforate at diode correspondence position, perforate size can just spill diode and
Welding position, diode two ends, when later stage diode damages, can change diode from tapping, without to group easily
Part causes damage.
Further, the size of described line box coordinates with the perforate size arranged at backboard, and described line box covers after installing
Perforate on backboard.
Further, described line box includes positive pole box body, negative pole box and middle box body.
Further, the quantity of bypass diode can be 2 or more than 2, and bypass diode is encapsulated in assembly.
Further, described backboard uses conventional photovoltaic backboard, or glass plate.
What this utility model realized has the beneficial effect that:
1, by being pre-welded to the busbar on diode both positive and negative polarity, directly diode is built in assembly；Simultaneously
By the busbar of diode one end being turned up extraction, and offer the mode of perforate by the one of diode on backboard or back of the body glass
End is connected with line box, and perforate can only be covered by the position of line box.Follow-up if it occur that diode damages, only need
Line box is dismantled, excavates silica gel and EVA, it is possible to change diode, wire terminal box again after replacing.
2, built-in due to diode, line box need not the reserved position placing diode, the volume of positive and negative polar curve box can
The least with do, and the line box of centre welds outside assembly owing to need not draw lead-out wire, can not want or have only to
One plastic sheet, therefore can save line box materials greatly.
3, need not in line box design diode circuit, save the copper sheet arranging diode, it is not necessary to consider diode
Heat radiation, line box body is long-pending can be reduced further.
4, built-in diode, the in advance good a bit of busbar of welding on the two poles of the earth of diode, will during component stack
In busbar and assembly, busbar connects, and operation is simple and reliable.
5, after the long-pending reduction of line box body, the casting glue consumption of the bonding required silica gel of corresponding and assembly and sealing is also
Can significantly reduce.
If 6 diodes damage, directly change diode, it is not necessary to change box body.
In sum, the cost of rosette can decline to a great extent.
