Description

Photovoltaic module junction box Technical Field The utility model relates to the technical field of photovoltaics, in particular to a junction box of a photovoltaic module. Background The photovoltaic module is a device for converting solar energy into electric energy, the junction box is arranged on the photovoltaic module and is used for outputting and converging current generated by each photovoltaic module to the system control box, in addition, the junction box also plays a role in protecting the solar photovoltaic module, a bypass protecting element is arranged in the junction box and is connected with a battery pack string in the photovoltaic module, and when battery pieces are damaged in the battery pack string or cause hot spot effect due to light shielding, the battery pack string with faults can be bypassed again from the photovoltaic system, so that adverse effects on the whole photovoltaic system are avoided. The existing photovoltaic module junction box can only re-bypass the faulty photovoltaic module or the battery pack string in the module from the photovoltaic power generation system when the photovoltaic module fails, but system operation staff cannot intuitively find the faulty photovoltaic module during inspection, so that difficulty is caused to system maintenance, and after that, some junction boxes capable of displaying the working state of the photovoltaic module appear, and a display screen is arranged on the junction box, so that the operation staff can clearly acquire the current condition of the photovoltaic module, thereby facilitating maintenance of the photovoltaic module, but in actual use, as the photovoltaic module 3 is obliquely arranged, and the photovoltaic module is spliced in a plurality of pieces, the photovoltaic module junction box 1 is also in an oblique state, and the display screen 22 is also in an oblique state, so that a part of display screens on the photovoltaic module can not be quickly and intuitively seen during actual inspection, and thus the use inconvenience exists. Disclosure of utility model The utility model aims to provide a photovoltaic module junction box, which solves the problems existing in the existing photovoltaic module junction box. In order to achieve the above purpose, the utility model adopts the following technical scheme: The utility model provides a photovoltaic module terminal box, includes box body and display module, the box body is used for installing at photovoltaic module back, display module includes swivel mount and display screen, the swivel mount upper end hinge in box body upper portion, the display screen sets up the swivel mount lower part, and is located the box body below, the display screen is set up to work as the box body is with the photovoltaic module slope, the display screen is with the swivel mount is rotatory so that the vertical setting of display screen. Further, the swivel mount includes panel and rotary rod, the rotary rod set up in the both sides edge of panel upper end, the upper end of rotary rod is provided with the pivot, the side on box body upper portion is provided with the commentaries on classics hole, the pivot is located in the commentaries on classics hole, the panel is set up to when the rotary rod does not follow the box body slope, the panel is located the box body below, the display screen sets up on the panel.
