Embodiment
The utility model provides that a kind of volume is little, the full glass assembly Whole Glass Assembly Terminal Box in the keel that can hiddenly be arranged at building, does not influence the attractive in appearance of building.
Below in conjunction with the drawings and specific embodiments the utility model is specifically described.
Referring to Fig. 3, this figure is the decomposition texture schematic diagram of first embodiment of the utility model.
First kind of embodiment of full glass assembly Whole Glass Assembly Terminal Box described in the utility model, a kind of full glass assembly Whole Glass Assembly Terminal Box, comprise that both end sides is provided with the box body 1 of line outlet 2, lid 3, be provided with a bypass diode 4 in the described box body 1, described bypass diode 4 the two poles of the earth connect an end of conductive connecting piece 6 respectively by two end connectors 5.A bypass diode 4 only is set in the utility model embodiment box body 1, and do not need the to conflux terminal and the band that confluxes are so box body 1 volume is very little.
Described bypass diode 4 and described end connector 5 can be fixedlyed connected by fixed forms such as soldering and rivet (not shown)s, can prevent that so described bypass diode 4 and conductive connecting piece 6 junctions are loosening.The utility model preferably adopts soldering to fixedly connected mode with rivet, makes fixing more firmly, and convenient welding is quick, further increases work efficiency.
Second kind of embodiment of full glass assembly Whole Glass Assembly Terminal Box described in the utility model: with reference to Fig. 4 and Fig. 5, relative first kind of embodiment of the utility model, described box body 1 line outlet 2 places also can be provided with a solidus body 8 with incoming line 7.Described conductive connecting piece 6 one ends connect described end connector 5, the other end extend in the described solidus body 8 from described box body 1 line outlet 2, the lead 10 of described cable 9 stretches in the described solidus body 8 from the incoming line 7 of described solidus body 8, and fixedly connected described cable 9 leads 10 1 ends by fixed forms such as weld tabs and rivet (not shown)s, avoided the artificial wiring of the traditional big Whole Glass Assembly Terminal Box characteristics of exoneration easily.Described bypass diode 4 connects the lead 10 of described cable 9 by described end connector 5.Again the trouble of connection cable 9 on described conductive connecting piece 6 when this connected mode is saved each use Whole Glass Assembly Terminal Box directly connects full glass assembly with the lead 10 of described cable 9 during use and get final product, makes things convenient for the wiring use, has saved operation.In described solidus body 8, connect the lead 10 of described conductive connecting piece 6 and described cable 9, can play middle transition and the effect that is connected.
Refer again to Fig. 4 and Fig. 5, be provided with gap 12 with described cable 9 insulated hulls 11 correspondence positions on the described solidus body 8.
Described solidus body 8 is cylindrical, and the diameter of described cylinder is generally 11mm, and long is 17.5mm.Because general general cable 9 is cylindrical, and solidus body 8 incoming lines 7 are drawn cable 9, so optimal way is designed to described solidus body 8 cylindrical, are streamlined with cable 9, and the streamline effect is visually more arranged, and are more attractive in appearance.And cylindrical stressed effect is stronger than the stress-bearing capability of shape such as square, increases anti-curved power, is difficult for making cable 9 to be fractureed.
Please be simultaneously with reference to Fig. 3, Fig. 4, described box body 1 upper surface can also evenly be provided with four jacks 14.With reference to Fig. 6, corresponding described jack 14 positions are provided with four pins 15 on the described lid 3.Can certainly set the jack 14 and the pin 15 of 2 or other number according to actual needs, as long as satisfy described jack 14 and pin 15 matches fixing.
With reference to Fig. 7, on the correspondence position of the sidewall of described jack 14, a screwed hole 13 can also be set.Can on the sidewall of the correspondence position of each jack 14, described screwed hole 13 be set all, also can on the sidewall of the correspondence position of one or two jack 14 described screwed hole 13 be set therein according to actual needs.
The pin 15 of described lid 3 is inserted in described box body 1 jack 14, can use screw to pass through described screwed hole 13 further fixing described pins 15, has better fixed effect like this.
The utility model preferred implementation after described lid 3 and box body 1 fastening, adopts encapsulating to seal.Adopt this kind sealing means can waterproof, it be better to have a better sealing effectiveness, has prolonged the useful life of Whole Glass Assembly Terminal Box.
For above-mentioned two kinds of embodiment, described box body 1 is a cuboid, and the overall dimension of described cuboid is generally long 41mm, wide 14mm, high 13.4mm.Because the utility model is mainly used in full glass/glass curtain wall, is installed on the side of described glass curtain wall, and the described full glass/glass curtain wall overall structure side of being generally body, avris is square, therefore described Whole Glass Assembly Terminal Box box body 1 is preferably cuboid.Described like this box body 1 and described full glass/glass curtain wall side edge shape coupling, more attractive in appearance, increased visual effect.According to practical experience, full glass/glass width of curtain wall is generally about 13.4mm, so box body described in the utility model 1 preferable width is 14mm, is convenient to be hidden in the keel of glass curtain wall.
The vertical range of described bypass diode 4 and described box body 1 inwall is more than or equal to 2mm, and this distance is convenient to described bypass diode 4 heat radiations.Certainly in proper range, increase the vertical range of described bypass diode 4 and described box body 1 inwall, make to have better radiating effect, can adopt 3mm or 4mm.
Preferably, described cable 9 diameters are smaller or equal to 6mm.Thinner cable 9 is convenient to be hidden in the gap between the full glass curtain wall component, plays effect attractive in appearance.
The course of work for the described Whole Glass Assembly Terminal Box of clearer explanation describes below in conjunction with accompanying drawing.
With reference to Fig. 1, the positive pole of described full glass assembly connects the positive pole of described Whole Glass Assembly Terminal Box, and the negative pole of described full glass assembly connects the negative pole of described Whole Glass Assembly Terminal Box.
In conjunction with as can be known aforementioned, the polarity of described full glass assembly is identical with the polarity of wherein solar cell string 17 or solar battery sheet 16, and the polarity of the bypass diode 4 in the polarity of described Whole Glass Assembly Terminal Box and the described Whole Glass Assembly Terminal Box is identical.
Under the normal running conditions, the electric current of described full glass component internal flows to the positive pole of described full glass assembly by the negative pole of described full glass assembly, and at this moment, described bypass diode 4 is not worked.
After the solar cell string 17 generation problems that connect between described Whole Glass Assembly Terminal Box both positive and negative polarity, electric current will directly flow through from described bypass diode 4, does not influence other solar cell string normal power generation of whole loop, work.As seen, 4 pairs of entire circuit of described bypass diode play a protective role.
General full glass assembly includes the plurality of solar cells string, can use a plurality of Whole Glass Assembly Terminal Box of the present utility model according to actual needs, they are installed in each side of described full glass assembly respectively, when realizing the Whole Glass Assembly Terminal Box function, because volume is little, install very hiddenly, increase visual effect.
For those skilled in the art, under the prerequisite of understanding the utility model principle, can also make some improvements and modifications, these improvement, retouching or expansion also should be considered as protection range of the present utility model.
