Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The technical problem to be solved by the embodiment is as follows: the photovoltaic module junction box generally uses sealant to fix and seal and assemble components such as diodes, the assembly mode can cause great influence on the heat dissipation performance of devices inside the photovoltaic module junction box, and the mode of generally reporting to waste the whole photovoltaic module or slowly removing the sealant when the internal devices are damaged is used for repairing.

In order to solve the above problem, the present embodiment provides a photovoltaic module junction box, which includes a junction box housing 20 and a device assembly bar;

the device assembling strip comprises a plurality of assembling modules, and each assembling module is fixed in a clamping groove 21 on the surface of the junction box shell 20; a plurality of assembly modules of the device assembly strip are the same module or different modules, and can be adjusted according to the specific function and structure of the junction box, and under the normal condition, the universal device assembly strip is set to be the same assembly module, so that the universal device assembly strip is convenient to be matched with the clamping groove 21 of the junction box shell 20 for installation.

The assembly module comprises a spacing plate 13 butted with the clamping groove 21 and an assembly plate 10 for assembling devices, and a sealing groove 30 is enclosed between the spacing plate 13 and the assembly plate 10; the partition plate 13 is buckled on a clamping groove 21 of the junction box shell 20, and a through hole 16 for wiring and gluing is formed in the partition plate 13; the sealing grooves 30 are connected in a conduction manner through the through holes 16 to form a sealing space inside the junction box.
