Description
Technical field:
The present invention relates to solar module, relate in particular to the terminal box of solar module.
Background technology:
The output voltage of monomer solar cell, electric current and power are all very little, and in general, output voltage has only about 0.5V, and power output has only 1～4W, can not satisfy the requirement as application of power.For improving power output, need a plurality of cells are rationally coupled together, and be packaged into assembly.In the more powerful occasion of needs, then need a plurality of assemblies are connected to become square formation, so that the bigger electric current of numerical value, voltage output to be provided to load.
The effect that solar battery component junction box is played in solar components is extremely important, and it is that the electric power that solar cell produces is defeated by outside link with electric line.Terminal box is arranged on the back side of solar module, backboard by silica gel and battery component sticks together, connection line in the terminal box should corresponding connection with the battery strings lead-out wire in the battery component, be connected with the output cable again, so just can make electric energy that battery component produces by the output of output cable.Diode is crucial electronic component in terminal box, and positional fault is set for it or the polarity wrong all can cause the entire cell assembly normally to export.Fig. 1 is a kind of fundamental diagram that is concatenated into battery component by 72 battery sheets, 72 battery sheets are divided into 6 rows, 12 of every rows, 72 battery sheets are connected mutually, from left to right count, draw the first lead-in wire A1 in first row's battery strings, between the second and the 3rd row, draw the second lead-in wire A2, between the 4th and the 5th row, draw the 3rd lead-in wire A3, draw the 4th lead-in wire A4 the 6th row, when preventing in the entire cell assembly that the individual cell sheet damages or the part is blocked, other battery sheet can prevent to produce when the solar module part is blocked the hot spot effect simultaneously normally to the output electric energy.Therefore must connect diode by the diagram requirement between four lead-in wires, otherwise when the solar module part was blocked, the whole solar cell component system was with regard to cisco unity malfunction, the part that is blocked can be sent a large amount of heats, and serious meeting burns out assembly.
At present, the encapsulation of solar module all is an assembled by hand, employed terminal box as shown in Figure 2, it comprises sheet metal 1 No. one, No. two sheet metals 2, No. three sheet metals 3, No. four sheet metals 4, diode 5, output cable 6 and junction box body 7, a sheet metal 1, No. two sheet metals 2, No. three sheet metals 3 and No. four sheet metals 4 from left to right parallel interval are distributed in the junction box body 7, draw four lead-in wire A1～A4 in the battery sheet string from battery component and be welded on sheet metal 1 respectively No. one, No. two sheet metals 2, on No. three sheet metals 3 and No. four sheet metals 4, and four lead-in wire A1～A4 receive on the corresponding sheet metal at the tape welding that confluxes with metal respectively on the same straight line, in connection procedure in order to ensure four the lead-in wire A1～A4 between mutually insulateds, the first lead-in wire A1 and the 4th lead-in wire A4 are positioned at one deck when assembling, the second lead-in wire A2 and the 3rd draws A3 and is positioned at another layer, separate with the EVA insulating barrier between two-layer, two output cables 6 link to each other with No. four sheet metals 4 with a sheet metal 1 respectively, at a sheet metal 1, No. two sheet metals 2, be connected to diode 5 respectively between No. three sheet metals 3 and No. four sheet metals 4, the terminal box of this solar module connects and adapts to the hand assembled technological requirement fully.
In order to realize the automated production of solar module, electrode connecting structure in the existing terminal box can not satisfy the requirement of automation packaging technology, in the automation packaging technology, require four lead-in wire A1～A4 in the battery sheet string must be positioned at same one deck, otherwise on the automation assembly line, must increase complicated Sheet turning device, not only increase the machinery of automatic assembly line, the complexity coefficient of automatically controlled design, and will increase considerably the cost of automatic assembly line, the reliability of whole piece assembly production chain also can be affected simultaneously.For this reason, the applicant has developed a kind of solar assembly junction box that is applicable to the automation assembling.
Summary of the invention:
In order to satisfy the automatic production process requirement of solar module, the invention provides a kind of solar assembly junction box of suitable automation assembling usefulness, adopt this solar assembly junction box, can satisfy four lead-in wires layer wiring setting and the nonoverlapping wiring requirement together in the battery sheet string, guarantee the output of battery component electric energy.
The technical solution adopted in the present invention is:
The solar assembly junction box of described a kind of suitable automation assembling usefulness, it comprises sheet metal No. one, No. two sheet metals, No. three sheet metals, No. four sheet metals, diode, output cable and junction box body, a sheet metal, No. two sheet metals, No. three sheet metals and No. four sheet metals from left to right parallel interval are distributed in the junction box body, and the upper end is concordant, it is characterized in that: the length of a sheet metal and No. four sheet metals is greater than the length of No. two sheet metals and No. three sheet metals, difference between the two is slightly less than conflux band and straight line metal of L shaped metal and confluxes and be with difference in height in the horizontal direction, between No. two sheet metals and a sheet metal, be connected to diode, between No. four sheet metals and No. three sheet metals, be connected to diode, between a sheet metal and No. four sheet metals, be connected to diode, from battery sheet string, draw the extension downwards synchronously of first lead-in wire and the 4th lead-in wire, and by L shaped metal conflux the band link to each other with No. three sheet metals with No. two sheet metals respectively, second lead-in wire confluxes to be with by the straight line metal with the 3rd lead-in wire and links to each other with No. four sheet metals with a sheet metal respectively, and two output cables link to each other with No. three sheet metals with No. two sheet metals respectively.
