Junction box capable of being arranged at side face of solar energy photovoltaic module

Abstract

The invention provides a junction box capable of being arranged at the side face of a solar energy photovoltaic module, belonging to the technical field of a solar energy source component. The junction box comprises a box body, a bypass diode, a first leading-out terminal, a second leading-out terminal and a box cover, wherein one end of the box body forms into a first socket, the other end of the box body forms into a second socket, and the middle of the box body forms into a cavity; a first base pin of the bypass diode is connected with one end of the first leading-out terminal, the other end of the first leading-out terminal extends into the first socket, the second base pin of the bypass diode is connected with one end of the second leading-out terminal, and the other end of the second leading-out terminal extends into the second socket; and the box cover is matched with the box body. The junction box is characterized by further comprising a movable clamping piece which is matchedwith one side of the box body, the lower part of the other side of the box body extends to be provided with a positioning side edge, and the positioning side edge corresponds to the lower part of themovable clamping piece. The junction box has the advantages that the environment protection can be guaranteed and the installation cost can be reduced due to the material consumption-free installation, the quick installation can be realized and the work efficiency can be improved, the external force collision resistance can be enhanced, and the solar energy photovoltaic module can be guaranteed to be durable and normal in working.

Description

technical field [0001] The invention belongs to the technical field of solar power supply components, and in particular relates to a junction box suitable for being installed on the side of a solar photovoltaic module. Background technique [0002] The solar photovoltaic module mentioned above is the abbreviation of solar photovoltaic module components (the same below). As known to those skilled in the art, the junction box of a solar photovoltaic power generation module is an important part for outputting solar power, including a junction box body, a bypass diode disposed in the box body, wires and cables, and cable connectors. The junction box is used as a transition device connecting the lead wires of the solar cell to the external lead wires. The function of the bypass diode set inside is to prevent reverse charging from damaging the solar photovoltaic cells and prevent the entire solar photovoltaic cell from being damaged due to a short circuit of a solar photovoltaic c...

Problems solved by technology

However, due to the lack of structure of the junction box itself in this patent solution, it needs to be fixed with adhesives during installation, otherwise it cannot be combined with the side of the photovoltaic module. For details, please refer to the schematic diagram in Figure 4 of the patent specification

From this structure, it can be seen that the following technical problems will be exposed in practical applications: first, due to the need to rely on auxiliary materials, that is, adhesives for installation, the installation is relatively cumbersome and the installation cost is high; second, the installation efficiency is low, and the installation workers The labor intensity is high; the third is that the weather resistance effect of adhesives such as glue is fragile and easy to age, so it is difficult to guarantee a long-lasting stabilization effect that usually takes as long as 20-25 years. Once it loosens or even falls off, it will be serious. Damage to the solar photovoltaic module; Fourth, because it is installed with the help of adhesives, once it is impacted by an external force, there is a risk of falling off
