Photovoltaic junction box body convenient to detach

Abstract

The invention relates to a photovoltaic junction box body convenient to detach, which comprises a box frame, a box bottom, a box cover and a sealing ring, wherein edges of the box frame are provided with a plurality of first clamping block, a wiring positive outlet and a wiring negative outlet; a first clamping group and a second clamping group are arranged on the inner wall of the box frame, and the first clamping group comprises two second clamping blocks, a first clamping slot and a second clamping slot; a plurality of terminal installation grooves are formed in the box bottom, and insertion plates are arranged on the box bottom; and a plurality of first buckling blocks are arranged on the side wall of the box bottom, and each first buckling block comprises a side plate and a hooking block; a second sealing groove is formed in the box cover, a plurality of second buckling blocks are arranged on the side wall of the box cover, each second buckling block comprises an insertion block and a connecting block, and the outer wall of each connecting block is provided with a notch. The photovoltaic junction box body is novel in structure and reasonable in design, avoids the traditional fixing way of tin soldering, is applied to a photovoltaic junction box, is stable and convenient to install, is favorable for reducing the cost, and is suitable for large-scale production.

Description

technical field [0001] The invention relates to an easily disassembled photovoltaic junction box box, belonging to the technical field of electrical connectors. Background technique [0002] The photovoltaic junction box is a connector between the solar cell array composed of solar cell components and the solar charging control device. It is a comprehensive design that combines electrical design, mechanical design and material science. The solar photovoltaic module junction box is very important in the composition of the solar module, and its main function is to connect the electricity generated by the solar cell with the external lines. [0003] The junction box in the prior art is mainly composed of three parts: the box body, the cable and the metal connector, which are glued together with the backplane of the component through silica gel. The line is connected with the external cable, so that the component is connected to the external cable. There are diodes in the junct...

AI Technical Summary

Problems solved by technology

[0003] The junction box in the prior art is mainly composed of three parts: the box body, cables and metal connectors, which are glued together with the back plate of the module through silica gel, and the outgoing lines in the module are connected together through the internal lines in the junction box. The lines are connected with the external cables to make the components conduct with the external cables. There are diodes in the junction box to ensure that the components can work normally when the light is blocked. Most of the bus strips are fixed by soldering. The disadvantage of this assembly method is that it is inconvenient to operate when welding the confluence belt, and it affects the appearance and is difficult to overhaul. Therefore, it is of great significance to design a photovoltaic junction box that is beautiful, stable, and easy to disassemble.
