Description

The box that confluxes that is used for solar module

Technical field

The utility model relates to a kind of box that confluxes, and especially relates to a kind of box that confluxes that is used for solar module.

Background technology

At present, solar power generation adopts the matrix compound mode, and will organize solar module more and link together, be electric energy with conversion of solar energy.Usually the lead with every group of solar module directly bundlees, is fixed in the insulation spool; Between two groups of adjacent solar modules according to voltage condition; Through confluence copper bar and line nose; Be connected to the grid after inserting inverter by series connection and/or parallel way again, finally form the whole generating system.The said structure form can increase the conductor length of every group of solar module, lead need specific customization just can, the caliber of institute's distribution pipe is bigger, the use amount of lead, confluence copper bar and line nose is all bigger, the overall routing mode is comparatively complicated, it is also higher to require.Therefore, adopt the said structure form, make the long construction period of electricity generation system, efficient is low, cost is higher.In addition, if lead goes wrong, be difficult to detect.

The utility model content

The utility model technical problem to be solved provides a kind of box that confluxes that is used for solar module, adopts the box that originally confluxes, and makes that short construction period, efficient height, the cost of electricity generation system are lower.

For solving the problems of the technologies described above; The utility model provides a kind of box that confluxes that is used for solar module; It comprises box body that insulating material processes, respectively connect one by one anodal some first leads of plurality of solar cells assembly, connect some second leads of plurality of solar cells assembly negative pole one by one respectively; Have two entrance holes and two wire holes on the box body; Described first lead, second lead pass two entrance holes respectively and put in the box body, are provided with two in the box body and adopt metal materials to process and the connector that confluxes of space, and a privates and privates pass two wire holes respectively and put in the box body; First lead and the privates that put in the box body are electrically connected through the connector that confluxes, and second lead and the privates that put in the box body are electrically connected through another connector that confluxes.

For the purpose of the concise description problem, all abbreviate the box that originally confluxes as in the face of the said box that confluxes that is used for solar module of the utility model down.

After adopting above structure; Some first leads are electrically connected with a privates through the connector that confluxes; Some second leads are electrically connected with privates through another connector that confluxes; So through two connectors that conflux in the box that originally confluxes; Can distinguish fixing exactly corresponding lead (that is: fixes a privates with some first leads that are connected plurality of solar cells assembly positive pole respectively one by one; Privates are fixed with some second leads that are connected plurality of solar cells assembly negative pole respectively one by one), the electric current that makes the plurality of solar cells assembly produce outwards flows through a privates, privates after confluxing.Like this, according to voltage condition,, by being connected to the grid behind series connection and/or the parallel way access inverter, finally form the whole generating system again between the plurality of solar cells assembly through the box that originally confluxes.Therefore, can reduce the conductor length of every group of solar module, lead need not specific customization, and the caliber of institute's distribution pipe is less, and the use amount of lead is less, and the overall routing mode is comparatively simple, requirement is also lower.

In sum, adopt the box that originally confluxes, make that short construction period, efficient height, the cost of electricity generation system are lower.

The said connector that confluxes by housing screw, pressing plate, be fixed in the box body Connection Block on the diapire and form; The U-lag hole that the top of Connection Block has a confession respective wire termination to penetrate; Two openings of slotted eye are positioned on the end face of Connection Block; Be in the stage casing that end face that pressing plate between two openings of slotted eye passes Connection Block gets into slotted eye and push down the termination of respective wire; Housing screw spins with Connection Block after running through the termination of pressing plate, respective wire, makes the termination of respective wire be pressed in the stage casing of slotted eye through housing screw, pressing plate.

As the optimization of the utility model, conflux and locate to be provided with a dividing plate between the connector in two of said box body inherences, so that box body inside is divided into two isolated each other chambers.

Like this, first lead and privates are in the chamber, and second lead and privates are in another chamber, thereby avoid described lead to produce interference each other.
