Abstract
The utility model discloses an energy-saving photovoltaic module single outgoing wire junction box. The structure comprises a junction box, a circuit block, wiring terminals, a concave type connector, a waterproof joint, a connecting wire, a convex type connector and a cover plate, wherein the junction box is fixedly connected with the cover plate, the circuit block and the wiring terminals are arranged inside the junction box, the circuit block is provided with the wiring terminals, one end of the connecting wire is connected with one of the wiring terminals, the other end of the connecting wire is connected with the convex type connector, and the other wiring terminal is connected with the concave type connector. The energy-saving photovoltaic module single outgoing wire junction box shortens the length of the connecting wire, reduces the wire resistance caused by the length of the circuit, improves the transmission efficiency of the circuit, reduces current loss while reducing the material consumption, and can reduce the cost.
Description
Technical field
The utility model relates to field of photovoltaic power generation, and particularly a kind of single outlet terminal box that improves transmission of effect is specially a kind of energy-saving photovoltaic module list outlet terminal box.
Background technology
Solar power generation principle is photovoltaic effect, and produce faint electron stream, because its electron stream does not exist energy inertia, the resistance each respective link serial connection point being produced at current flowing all can be to electric current loss to some extent, in transmitting procedure, will consider the resistance existing in transmission link, in the interconnection technique of solar photovoltaic assembly, mainly connect the connection between other electrical equipment or assembly by terminal box, in the serial connection of assembly, optimize connecting link, reduce the distance, on proposing high-octane transmission, reducing the wastage plays certain impact.
Existing terminal box is that two outlets connect, and connecting line is longer, produces larger line resistance, has reduced the efficiency of transmission of circuit, has increased the loss of electric current, has increased the consumption of material simultaneously, is unfavorable for reducing costs.
Utility model content
In order to solve problems of the prior art and deficiency, the utility model provides a kind of energy-saving photovoltaic module list outlet terminal box, the wiring length that has effectively reduced photovoltaic component terminal box connector, has reduced line resistance, has improved the efficiency of transmission of photovoltaic module.
The purpose of this utility model realizes by the following technical solutions.
A kind of energy-saving photovoltaic module list outlet terminal box, in structure, comprise: terminal box, circuit block, binding post, matrix connector, water joint, connecting line, convex connector, cover plate, terminal box is fixedly connected with cover plate, circuit block, binding post are arranged in terminal box, on circuit block, be provided with binding post, connecting line one end is connected on a binding post, and the connecting line other end is connected on convex connector, and another binding post is connected with matrix connector.Quick rich, two marks, middle Thailand, profit are safe.
On described connecting line, there is water joint in terminal box and cover plate joint cover.
Described matrix connector one end is furnished with silicone rubber O-ring and locking nut can be fixed with terminal box, matrix connector Nei center plug-in unit is connected with another binding post, the external convex connector of the other end, described connecting line is connected with splicing ear through water joint.
When connecting, above-mentioned composite type photovoltaic module wiring only convex connector in terminal box need be inserted on the matrix connector in another block assembly.
The end that picks out of above-mentioned binding post only has a connecting line.
Single outlet terminal box of the present utility model shortened connecting line length, reduced the line resistance producing because of line length, improved the efficiency of transmission of circuit, reduced the loss of electric current, reduced the consumption of material simultaneously, can reduce costs.
