Abstract

The invention provides a photovoltaic junction box, comprising a box body, a power management module, a positive electrode cable and a negative electrode cable, wherein the box body comprises an uppercover body and a bottom shell; The positive electrode cable and the negative electrode cable pass through the box body and are connected with the power management module; A limit bit block is mountedon that positive electrode cable and/or the negative electrode cable; The bottom shell is provided with a first groove, the bottom shell is provided with a second groove corresponding to the first groove, and the first groove and the second groove form a clamping groove; Wherein the limiting block is clamped into the card slot. The invention solves the defect that the existing photovoltaic connector can not effectively fix the positive electrode cable and the negative electrode cable, which leads to easy displacement and deformation by fixing the limiting block on the positive electrode cableand the negative electrode cable, and fixing the limiting block through the upper cover body and the bottom shell.

Description

technical field [0001] The invention relates to the technical field of photovoltaic junction boxes, in particular to a photovoltaic junction box. Background technique [0002] In the existing photovoltaic junction box, the positive cable and the negative cable are directly inserted into the photovoltaic junction box, and the photovoltaic junction box is assembled together by directly snapping the upper and lower boxes, which cannot effectively fix the positive cable and the negative cable, resulting in easy displacement and deformation. [0003] For example, the patent application number is CN201620845867.1 "A Photovoltaic Junction Box with High Stability". The photovoltaic junction box is directly buckled by the upper and lower boxes, and the positive and negative cables are easy to shift and deform. Contents of the invention [0004] (1) Technical problems to be solved [0005] The object of the present invention is to provide a photovoltaic junction box, which solves ...
