Abstract

The invention discloses an isolation free crystalline silicon solar battery component, the bus bars on ends of which are led out in parallel to a central line of a glass plate at an interval without overlapping, then curved upwards in a perpendicular way at a position corresponding to that of a jack on a terminal box, passing through a cable entry arranged on a back plate and inserted into the jace on the terminal box. The leading-out lines on two ends and leading-out lines between two ends of serially connected bypass diodes in the terminal box meet the requirement of the jack on the terminal box. Jacks of external bus bars are positioned on one end of the terminal box closed to edge of the glass plate and jacks of internal bus bars are positioned on one end of the terminal box back to edge of the glass plate. The bus bars are not overlapped from each other any more and not overlapped with the battery sheet so as to save the insulation isolation, save a series of processes for installing isolation, reduce the manufacturing cost and time for components, avoid generating bubbles owing to isolation in the package process and remarkably promote the product qualification rate.

Description

A kind of nothing is isolated crystal silicon solar battery component

Technical field

The utility model relates to a kind of crystal silicon solar battery component.

Background technology

In the production of crystal silicon solar assembly, lamination is the indispensable operation during it is produced, put each the crosstalk pond sheet that connects on the glass plate that is covered with hot melt adhesive film EVA according to certain layout, need then battery strings is drawn battery strings by lead-in wire, by busbar electric current is drawn again, last, spread the component package material EVA and the backboard that are a bit larger tham the glass plate area, at backboard appropriate location opening, busbar is drawn, so that subsequent handling is installed terminal box.As Fig. 1, shown in Figure 2, connecting in traditional terminal box and lacking a plurality of bypass diodes of 1 than busbar quantity, each busbar is connected the bypass diode D1 of polyphone, the lead-out wire at D2 and D3 two ends and each bypass diode D1, on the lead-out wire of drawing between D2 and the D3, the plug wire hole A ' of terminal box, B ', C ' and D ' are positioned on the straight line, by force of tradition, people often are with parallel busbar 1,2,4,5 to the parallel bending in the center of glass plate, vertically draw the busbar wire hole that has on the backboard again, be connected with terminal box 3 again, because busbar 1,2,4,5 needs that are connected with terminal box 3, this outbound course of busbar causes the busbar 1 of outer end, 4 with inner busbar 2,5 and the battery sheet have overlapping part, in order to solve busbar and busbar, short circuit problem between busbar and the battery sheet, need overlapping part is separated with insulating, available technology adopting between the busbar or the mode that installs isolation between busbar and the battery sheet additional separate overlapping busbar and overlapping busbar and battery sheet.The use of isolating has caused the local complexity of assembly, in encapsulation process, uses the part of isolating to be easy to generate bubble, has increased the probability that substandard product occurs, and simultaneously, uses and isolates in the time of can increasing assembly production cost and worker.

Summary of the invention

The utility model solves the above-mentioned problems in the prior art exactly, provides a kind of nothing that does not need to isolate to isolate crystal silicon solar battery component.

For addressing the above problem, technical solution of the present utility model is: a kind of nothing is isolated crystal silicon solar battery component, each battery strings, battery strings lead-in wire, busbar and terminal box that it comprises glass plate, backboard, is made up of single crystal silicon cell sheet; The busbar zero lap ground liftoff center line to glass plate of spacer is parallel draws relatively for each of two ends, each busbar at two ends arrive with terminal box on corresponding position, plug wire hole position the time, crooked vertically upward, pass through the wire hole that has at this place of backboard, insert again in the plug wire hole on the terminal box and connect, in the terminal box bypass diode two ends lead-out wire of each series connection and between the lead-out wire plug wire hole that satisfies terminal box require: the plug wire hole of each busbar of outer end is positioned at the end of terminal box near glass plate edge, and the plug wire hole of each busbar of inner end is positioned at a terminal box end of glass plate edge dorsad.

Because the utility model has adopted such scheme, each busbar of its outer end and each busbar of inner end are no longer crooked on glass plate, directly draw backboard, be connected with terminal box and get final product, like this, busbar is juxtaposition no longer just, also no longer overlapping with the battery sheet, thereby having saved insulation isolates, also just saved the series of processes of isolating has been installed, when having reduced assembly production cost and worker, avoided in encapsulation process, the generation of the bubble that causes because of isolation has improved product percent of pass greatly.The utility model production technology is simple, practical, is fit to produce in enormous quantities.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is further described:

As shown in Figure 3 and Figure 4, present embodiment is the crystal silicon solar battery component that 6 string battery strings are arranged.Each battery strings, battery strings lead-in wire, busbar 9,10,12,13 and terminal box 11 that it comprises glass plate 6, backboard 8, is made up of single crystal silicon cell sheet 7.Each busbar 9,10,12,13 zero lap ground at two ends at interval at least 5mm draw relatively to the center line of glass plate 6 is parallel apart from ground, each busbar 9,10,12,13 at two ends arrive with terminal box 11 on the corresponding position in plug wire hole A, B, C and D position the time, crooked vertically upward, pass through the wire hole that has at this place of backboard 8, insert again in plug wire hole A, B, C and the D on the terminal box 11 and connect.Bypass diode D4, the D5 of series connection and the distribution mode of D6 are in the terminal box 11: the bypass diode D4 at two ends is parallel with D6, middle bypass diode D5 is vertical with D6 with the bypass diode D4 at two ends, the lead-in wire at the two ends of bypass diode D4 and D6, make jack A and jack D on a line, and be positioned at terminal box 11 a end near glass plate 6 edges, jack B and jack C are on a line, and be positioned at terminal box 11 end at glass plate 6 edges dorsad, jack A and jack B are on a line, and jack C and jack D are on a line.

Certainly; the utility model also has other multiple example; number as battery strings; the number of the bypass diode that it is corresponding; the distributing position of bypass diode and plug wire hole in the terminal box, the busbar of drawing change each position of direction etc.; under the situation of the utility model spirit and essence; those of ordinary skill in the art can make corresponding change and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
