[0031] It is worth mentioning that at least two protrusions 11 are provided on one side of the base 1, and a slot 12 corresponding to the protrusion 11 is provided on the other side of the base 1. The protrusion 11 is inserted into the slot 12 to connect and fix two adjacent bases 1, so that multiple junction boxes can be spliced ​​in this way;

[0032] It is worth mentioning that a retractable clamping block 5 is provided at the bottom of the base 1, and the clamping block 5 is provided with a first undercut portion 51. The clamping block 5 is provided with a spring 52 and abuts against the base 1. The clamping block 5 protrudes from the end surface of the base 1. First, the clamping block 5 is pulled outward, and the spring 52 is compressed to store energy, and the base 1 is placed on the mounting rail. When the second undercut portion 14 is buckled on one side of the mounting rail, the force applied to the clamping block 5 is released, and the spring 52 releases the elastic force to the clamping block 5, so that the clamping block 5 retracts, and the first undercut portion 51 is buckled on the other side of the mounting rail, so that the junction box is fixed on the mounting rail;

[0036] It is worth mentioning that the multiple first convex portions 22 communicate with each other. The protruding distance of the first convex portion 22 is greater than the protruding distance of the blocking portion 23. When rainwater flows along the inclined surface 24 to the blocking portion 23, since the protruding distance of the first convex portion 22 is greater than the protruding distance of the blocking portion 23, the rainwater will drip down along the outer wall surface of the first convex portion 22, thus preventing rainwater from entering the wiring hole 21.
