[0029] Three terminal blocks 10 are evenly installed inside the mounting bracket 5. The terminal ends of the lamp holder 3 sequentially pass through the lower surfaces of the lamp housing 1 and the rotating housing 4 and are connected to the three terminal blocks 10 in the inner cavity of the rotating housing 4. In this embodiment, three conductors can be fixedly installed in the inner cavity of the lamp housing 1, so that the three terminal ends of the lamp holder 3 pass through the lower surface of the lamp housing 1 and are respectively connected to the three conductors. Then, the ends of the connecting wires of the three conductors sequentially pass through the second arc surface 11 and the first arc surface 41 and are respectively connected to the three terminal blocks 10. The terminal blocks 10 are connected to the external circuit through wires.

[0030] Wherein, an external thread 13 is provided on the outer surface of the lamp housing 1. The lamp housing 1 is connected with a locking nut 14 through the external thread 13. When the signal lamp is installed on the electrical equipment, the installation part of the electrical equipment can be clamped by the lamp housing 1 and the locking nut 14, so as to ensure the stability of the installation of the plug-in indicator lamp.

[0031] Working principle:

[0032] By providing a concave first arc surface 41 on the lower surface of the rotating housing 4, providing a convex second arc surface 11 above the lamp housing 1, and through the action that the ends of the two plug plates 6 are rotationally connected to the rotating shaft 8 through the rotating holes 61, the whole rotating housing 4 can rotate around the rotating shaft 8 as the center and slide relative to the upper surface of the lamp housing 1. During the rotation, the two plug plates 6 move in the two strip-shaped grooves 12.

[0033] Therefore, when the assembly position of the signal lamp needs to be higher or lower, the rotating housing 4 can be rotated, as Figure 8 shown, so that there is a certain angle between the rotating housing 4 and the lamp housing 1, and the rear cover 9 on the upper surface of the rotating housing 4 can be rotated to the outer side to solve the problem that the viewing angle is inconvenient for the staff during installation, so as to facilitate the staff to carry out the work of assembling, wiring, fixing and locking.

[0034] When the signal lamp needs to be disassembled or installed, first rotate the rotating housing 4 so that the axes of the rotating housing 4 and the lamp housing 1 are on the same straight line, as Figure 7 shown, so that the locking nut 14 can be smoothly removed or tightened, and then the whole signal lamp can be disassembled and assembled with the installation part of the electrical equipment.

[0035] Embodiment 2, as a further preferred solution of Embodiment 1, three avoidance holes 91 are provided on the surface of the rear cover 9. The avoidance holes 91 are arranged corresponding to the wiring base 10. Through the avoidance holes 91, the wire can pass through the avoidance holes 91 and then be connected to the wiring base 10. In this embodiment, a plurality of buckles 92 are provided on the rear cover 9, and a plurality of clamping holes 42 are provided on the upper side surface of the rotating housing 4. The buckles 92 are engaged with the clamping holes 42.

The screw base 101 is threadedly connected to the locking screw 102 through the threaded hole. A voltage-conducting sheet 103 is provided between the locking screw 102 and the upper surface of the screw base 101. The wiring end of the conductor is connected to the voltage-conducting sheet 103. Therefore, when wiring, the external wire can be fixed to the locking screw 102, and then the locking screw 102 is screwed onto the screw base 101, so that the external wire can be pressed against the surface of the voltage-conducting sheet 103, and thus the conductive connection between the external wire and the end of the connecting wire of the conductor can be achieved through the voltage-conducting sheet 103.

[0037] Embodiment 4, as a further preferred solution of Embodiment 1, a gasket 15 is provided between the locking nut 14 and the lamp housing 1. By providing the gasket 15, the fastening and stability of the locking nut 14 when clamping the installation part of the electrical equipment can be ensured.
