Low-voltage cable branch joint and low-voltage cable branch box

The utility model discloses a low-voltage cable branch joint and a low-voltage cable branch box. Technical key points of the low-voltage cable branch joint are as follows: annular tooth spaces are machined in all of vertical-edge pipe openings and horizontal-edge pipe openings of perpendicular pipes of a joint body cover; perpendicular parts of the perpendicular pipes are penetrated through a joint body; round holes are machined at positions of two adjacent faces of the joint body, relative to a vertical-edge pipe and a horizontal-edge pipe of each perpendicular pipe, wherein the two round holes are in communication and internal threads are machined in round holes corresponding to the horizontal-edge pipes. Intermediate sleeves are arranged in vertical-edge pipe openings of the joint body cover. Annular tooth spaces are machined in the intermediate sleeves and cables are arranged to be inserted into the intermediate sleeves. Cable terminations are inserted into round holes of the joint body, corresponding to the vertical-edge pipes and then pressed tightly through wire pressing nuts. Technical key points of the low-voltage cable branch box are that four rows of low-voltage cable branch joints are installed on a trapezoidal folding plate on a bottom plate of a box body. The low-voltage cable branch box is capable of realizing load distribution safely and efficiently.
