Terminal box and solar cell module using same

Abstract

The invention provides a terminal box and a solar cell module using the same. The terminal box comprises a box body assembly, cover bodies and electrical conduction terminal sets, wherein the box body assembly comprises at least two box bodies which are arranged separately, and an accommodating groove is arranged in each of the box bodies; the number of the cover bodies are the same with that of the box bodies and are respectively covered on the upper portions of corresponding box bodies; the electrical conduction terminal sets are accommodated in accommodating spaces of the box bodies and comprise first electrical conduction terminals and second electrical conduction terminals which are located on two sides of the accommodating spaces, and the electrical conduction terminals are arranged on the same straight line; and adjacent box bodies are in series connection through leads. The terminal box and the module have the advantages that a plurality of box bodies are arranged separately, the safety coefficient is improved, the production cost is reduced, and the power supply efficiency is improved.

Description

technical field [0001] The invention relates to a junction box, in particular to a junction box with a separate box body and a solar cell assembly using the junction box. Background technique [0002] The solar cell module junction box is a connector between the solar cell array formed by solar cell modules and the solar charging control device. It is a cross-field comprehensive design that combines electrical design, mechanical design and material science. The solar cell module junction box is very important in the composition of the solar module, and its main function is to connect the power generated by the solar cell with the external circuit. The junction box is glued to the back plate of the module through silica gel, and the lead wires in the module are connected together through the internal lines in the junction box, and the internal lines are connected to the external cables, so that the components and the external cables are connected. [0003] However, when the ...

Problems solved by technology

[0003] However, when the junction box is used in Building Integrated Photovoltaics (BIPV), the junction box is generally set as a long and narrow type, and the positive and negative cables are extended at both ends, and placed on the side of the solar panel. In the prior art, the number of junction boxes mentioned above is It is generally set to one, and a single junction box has a weak protective effect on the solar battery system. At the same time, the junction box is connected to the junction box on the other solar panels through cables. Due to the high cost of the cables and the power loss during the current transmission process bigger
