In some preferred embodiments, the surface of the first box body 11 and the second box body 12 is coated with a corrosion-resistant coating, so as to avoid the penetration and corrosion of the branching box 1 by moisture and the like, and prolong the service life of the equipment.

[0040] The line splitter 2 is arranged in the cavity of the line distribution box 1, the main cable enters the line splitter 2 from one end of the line distribution box 1, and the branch cable enters the line splitter 2 from the other end of the line distribution box 1, so that the main cable and the branch cable are connected through the line splitter 2. It can be understood that in some possible embodiments, the main cable is a low-voltage cable for supplying power to the lamp, and the branch cable is a power cable for the fixed lighting lamp.

[0041] Please refer to Figure 2 In this embodiment, the line splitter 2 includes a base 21, a cover plate 22 connected to the base 21, and three conductive terminal blocks 23 arranged in the base 21. The base 21 and the cover plate 22 are made of insulating materials such as ceramics and glass, and the three conductive terminal blocks 23 are made of copper conductive materials.

[0042] The three conductive terminal blocks 23 are arranged in the base 21 to prevent the conductive terminal blocks 23 from contacting other objects and reduce the risk of electric shock and contact short circuit. For the convenience of describing the conductive terminal blocks 23, one of the conductive terminal blocks 23 is described, which includes a main cable slot 231 and a branch hole 232. The main cable slot 231 is in a U-shaped groove structure, and the groove is used to place the main cable. The branch hole 232 is fixedly arranged on one side of the main cable slot 231, and the branch hole 232 is used to place the branch cable. The side of the main cable slot 231 away from the branch hole 232 is also provided with a main screw hole 233 and two auxiliary screw holes 234, and the main screw hole 233 and the two auxiliary screw holes 234 are arranged through the main cable slot 231, and the two auxiliary screw holes 234 extend into the branch hole 232. By screwing the screw into the main screw hole 233 and the auxiliary screw hole 234, the main cable is fixed in the main cable slot 231, and the branch cable is fixed in the branch hole 232, that is, the main cable and the branch cable are fixed in the conductive terminal block, thereby forming a complete current loop with complete conduction function.

[0043] In the embodiment, the base 21 is a multi-prism box structure, that is, one end is closed by a bottom cover, and the side is enclosed by a side wall to form a box shape. Preferably, it can also be a cylindrical shape and the like which is matched with the distribution box 1, so as to be installed in the distribution box 1. Three mounting grooves 211 are arranged in the base 21, and the three mounting grooves 211 are matched with three conductive terminal blocks 23. The three mounting grooves 211 are uniformly distributed in the base 21, that is, the three conductive terminal blocks 23 are respectively placed in the three mounting grooves 211. The base 21 is further provided with a through hole 212 matched with a main line groove 231 in the three conductive terminal blocks 23. The through hole 212 is located on the side of the base 21, and the through hole 212 penetrates the bottom plate. After the conductive terminal block 23 is installed in the mounting groove 211, the main line groove 231 is in an open state without shielding, and the main cable can be directly placed in the main line groove 231 for fixation after stripping and distribution, so as to improve the convenience of wiring operation. Three insertion holes 213 matched with distribution holes 232 in the three conductive terminal blocks 23 are arranged on the bottom cover of the base 21. The three insertion holes 213 are in communication with the three mounting grooves 211, so that after the conductive terminal block 23 is installed in the mounting groove 211, the distribution cable can be inserted into the distribution hole 232 through the insertion hole 213 for fixation. Three T-shaped holes penetrating the side wall are further arranged on the base 21. The T-shaped holes are avoidance holes 214, and the avoidance holes 214 are matched with main screw holes 233 and two auxiliary screw holes 234 of the conductive terminal block 23. That is, the three avoidance holes 214 are in communication with the three mounting grooves 211 respectively.

The avoidance hole 214 is a T-shaped hole penetrating the base 21. After the conductive terminal block 23 is installed in the mounting groove 211, the main screw hole 233 and the auxiliary screw hole 234 can be directly fixed with the screw without strict alignment with the avoidance hole 214, so that the fixing deviation of the conductive terminal block 23 and the base 21 is reduced, and the convenience of screw locking is improved. In some preferred embodiments, the base 21 is further provided with a sink matched with the avoidance hole 214. On the one hand, the locking efficiency of the screw and the main screw hole 233 and the auxiliary screw hole 234 is improved when the conductive terminal block 23 is fixed.
