Abstract
The invention relates to a three-in-one photovoltaic assembly junction box. The three-in-one photovoltaic assembly junction box comprises a box body and a base; the box body is connected with the base and is made of a heat conducting material; two wiring terminals are arranged in parallel between the box body and the base and are connected with each other through a diode; each wiring terminal is correspondingly connected with a bus bar on a photovoltaic assembly; and the wiring terminals and the diode are encapsulated through using heat-conducting glue. The three-in-one photovoltaic assembly junction boxes should be used in a group manner; and each group of three-in-one photovoltaic assembly junction boxes comprises a positive pole lead-out junction box and a negative pole lead-out junction box or comprises one or a plurality of intermediate lead-out-free junction boxes. With the three-in-one photovoltaic assembly junction box adopted, the loss of output power can be decreased, and at the same time, cell sheet arrays of the photovoltaic assembly can be grouped arbitrarily, and the voltage of each group of the cell sheet arrays can be reduced, and the normal operation of the assembly can be benefited.
Description
Technical field
The present invention relates to solar photovoltaic battery component terminal box, refer to especially a kind of three-in-one photovoltaic component terminal box.
Background technology
The terminal box of solar photovoltaic assembly all adopts a block assembly to join the mode of a terminal box at present, there are following two problems in this connected mode: 1. the busbar of guiding to terminal box in assembly, and between terminal box, stube cable is oversize, its conductor resistance is large, loss is large, causes the power output of assembly to decline; Due to only by a terminal box, the grouping of the cell piece of solar photovoltaic assembly is few, owing to dividing into groups, causes less the voltage of every group higher.
Summary of the invention
The object of the invention is to design a kind of solar photovoltaic battery component terminal box, make to guide in assembly the busbar of terminal box, and the cable length connecting between terminal box, reduced the decline of power output, the cell piece array of photovoltaic module can divide into groups arbitrarily simultaneously, can make every group of lower voltage, be more conducive to the normal operation of assembly.
The present invention for achieving the above object, adopt a kind of three-in-one photovoltaic component terminal box, comprise box body and base, described box body is connected with base, box body and base are made by Heat Conduction Material, between box body and base, parallel arrangement two binding posts, between two binding posts, by a diode, be connected, each binding post is corresponding to be connected with the convergent belt on photovoltaic module, use heat-conducting glue by binding post and diode package, described three-in-one photovoltaic component terminal box must be used in groups, in every group, comprise that positive pole is drawn terminal box and negative pole is drawn terminal box.Described anodal outlet box refers to that cable passes through opening and the positive terminal sub-connection on terminal box right side, and negative pole outlet box refers to that cable passes through opening and the negative terminals sub-connection in terminal box left side.
Described three-in-one photovoltaic component terminal box, can also comprise one or more middle without drawing terminal box.Middle without draw terminal box can according to actual conditions select need not, or with one, or more than one.
Described photovoltaic component terminal box, is that box body and base are connected to a fixed by ultrasonic bonding, guarantee the stable connection between them.
Described photovoltaic component terminal box, adopts snap fit to be connected between lid and box body.
Described photovoltaic component terminal box, the sealing means between lid and box body adopts casting glue sealing.
Described photovoltaic component terminal box, binding post and convergent belt adopt welding manner.
Described photovoltaic component terminal box can be used by split tandem compound, according to the lead-out mode of terminal box cable, can be divided into a left side (negative pole) draw, middle without drawing, right (positive pole) draw, and can not use in the middle of wherein without deriving structure, also can be one or more.
The binding post of above-mentioned photovoltaic component terminal box is connected with cable utilization riveted joint, and the fixing employing ultrasonic bonding of drawing of cable will be fixing between briquetting and box body.
Beneficial effect: 1, make to guide in assembly the busbar of terminal box, and the cable length connecting between terminal box, reduced the decline of power output.2, the cell piece array of photovoltaic module can divide into groups arbitrarily simultaneously, can make every group of lower voltage, is more conducive to the normal operation of assembly.
