Furthermore, the inner walls of the key 42 and the rail connection box 41 are fixedly provided with limit protrusions 49 which can be abutted against each other. The key 42 can be prevented from being separated from the rail coupling case 41 and thus from being disabled.

The rail assembly 2 of the first embodiment includes a rail body 21, and an inner wall of the rail body 21 extends inward to form a locking protrusion 214. Generally, there are two locking projections 214.

The electric device 9 is typically an LED lamp or a dc power supply or the like capable of being energized. The rail body 21 is mounted on a mounting object such as a ceiling of a room.

When the rail connecting box is used, the key 42 is moved to enable the key 42 to move towards the direction close to the center of the rail connecting box body 41, the inner wall of the steering groove 421 abuts against the steering groove 421 to enable the locking piece 43 to be retracted into the rail connecting box body 41, the electric device 9 and the rail connecting box 4 move upwards until the locking piece 43 is located above the locking protrusion 214, then the key 42 is moved to enable the key 42 to move towards the direction of the center away from the rail connecting box body 41, one end of the locking piece 43 is exposed from the side face of the rail connecting box body 41 and abuts against the locking protrusion 214, and therefore the electric device 9 and the rail connecting box 4 can be installed on the rail assembly.

Conversely, moving the key 42 moves the key 42 toward the center of the rail connecting box 41, retracts the locking member 43 into the rail connecting box 41, and moves the electrical device 9 and the rail connecting box 4 upward until the locking member 43 is located below the locking protrusion 214, so that the electrical device 9 and the rail connecting box 4 can be detached from the rail assembly 2.
