Technical field
The present invention relates generally to photovoltaic component terminal box.
Background technology
Photovoltaic cell is the device that the solar radiation energy is directly changed into electric energy, and photovoltaic module by the product that a plurality of photovoltaic cells connect and encapsulation forms, is the elementary cell of battery array in the photovoltaic generating system just.Photovoltaic component terminal box is the crucial jockey that solar components is made system, and the effect of terminal box is to prevent from producing when the solar components part is blocked the hot spot effect.If damaging or connect not firm meeting, terminal box cause terminal box to work, thereby when the solar components part is blocked, whole solar components system is with regard to cisco unity malfunction, and the part that is blocked will be sent a large amount of heats, and serious meeting burns out assembly.In the prior art; such as accompanying drawing 1; shown in 2; photovoltaic component terminal box comprises loam cake 100 and lower cover 200; lower cover 200 is usually by the surface of beating the glue mode and be fixed in photovoltaic module; realize and being connected of photovoltaic module by a cover communication apparatus between loam cake 100 and the lower cover 200; this communication apparatus is comprised of the plug 102 of the lower surface that is arranged on loam cake 100 and the socket 201 that is arranged on the upper surface correspondence position of lower cover 200; the sheet that confluxes of photovoltaic module then is welded on the solder joint that is conducted with socket 201 by the mode of welding; like this; when loam cake 100 and lower cover 200 are combined; be positioned at the socket 201 that plug 102 inserts on the loam cake 100 are provided with clamping part; thereby realize the operating circuit of photovoltaic component terminal box inside is interconnected by conflux sheet and photovoltaic module, play the effect of protection photovoltaic module.From foregoing, can find out that the photovoltaic component terminal box of this structure needs the sheet that confluxes is respectively welded on the solder joint of each socket in installation process, operate comparatively loaded down with trivial detailsly, and installation effectiveness is low; In addition, be understandable that, under this mounting means, photovoltaic module need to be by realizing behind the sheet that confluxes, solder joint, socket, the plug and being connected of operating circuit, connected mode is complicated and because resistance inconsistent, cause the electric current in each branch road to cause variation, affected the service behaviour of terminal box.For this defective, a kind of improved procedure of the prior art is to use snak link to be directly fixed in the terminal box sheet that confluxes, therefore but under this mode, conflux sheet and the contact area between the snak link too small (line contacts) are easy to cause connect the problems such as unstable, unreliable.
Summary of the invention
For overcoming above-mentioned shortcoming, the technical problem to be solved in the present invention be to provide a kind of installation simple, connect reliable photovoltaic component terminal box.
In order to reach above purpose, the technical solution used in the present invention is: a kind of photovoltaic component terminal box is mounted to the lower cover of photovoltaic module and is bonded to the described lower loam cake that covers when work when it is included in work; Cover on described and be provided with the operating circuit module, described operating circuit module comprises the connecting circuit made by copper sheet, is installed on a plurality of bypass diodes in the described connecting circuit, cover towards described loam cake under described and be formed with a plurality of briquettings, on each described briquetting snak link is installed; Correspondence is provided with catching groove on the connecting circuit in the described loam cake, after the sheet that confluxes of photovoltaic module is walked around described snak link when mounted, be pressed in the described catching groove in described loam cake is incorporated into the process of lower cover, described catching groove has the flange that smooth being close to is pressed on the outer surface of the sheet that confluxes in the described catching groove.
Preferably, described snak link is " n " shape and is removably installed on the described briquetting.
Preferably, the bottom of described snak link is clamped in the both sides of described briquetting.
Preferably, the width on the top of described snak link is slightly larger than the bottom, and in the sheet that will conflux was pressed into process in the described catching groove, the top of described snak link resetted so that the sheet that confluxes is clamped in the described catching groove by elastic compression and after passing described catching groove.
Preferably, has the first chamber in the described loam cake, has the second chamber in the described lower cover, described operating circuit module is arranged in described the first chamber, described briquetting is arranged in described the second chamber, described lower covering has the opening that the provide (shenglvehao)with foreign exchange flow penetrates, and when described loam cake was incorporated into described lower cover, described the first chamber, the second chamber consisted of the sealed chamber with extraneous gas-liquid sealing.
Preferably, also be included in anodal jockey and the negative pole jockey that is electrically connected with described operating circuit module in the described sealed chamber.
Owing to adopted technique scheme, in the process of installing, the sheet that confluxes of photovoltaic module only need pass corresponding opening and bending in the snak link surface, afterwards loam cake is incorporated into the electrical connection process that can realize photovoltaic module in the lower cover process afterwards, in whole process, need not welding, and sheet directly is connected with the copper sheet circuit owing to conflux, and connects reliably, has guaranteed the electric property of photovoltaic component terminal box.
