However, the above scheme has the following disadvantages: due to the use of a power cord connection, the internal space of the power box is occupied, the production cost of the track light is increased and it is not conducive to reducing the volume of the power box. At the same time, during the assembly process, it is necessary to manually tighten the screws or use a welding gun for welding, which further increases the complexity of assembly, further increases the production cost of the track light, and is not conducive to the promotion of the track light power box.

[0032] Track lights are lamps installed on power-connected tracks. The illumination angle can be adjusted at will. They are generally used as downlights in places where lighting is needed. They are mostly used for commercial purposes, such as jewelry, clothing, museums or squares. Ordinary track lights can usually be slidably installed in a matching power-connected track. The conductor in the power-connected track is input with a supply voltage, and the power box of the track light is connected to the power-connected track through a rotatable conductive connector. The conductive sheet on the conductive connector abuts against the conductor in the power-connected track to power on the track light.

[0033] In the existing design, the track light power box generally includes: a power box shell, and a control circuit board installed in the power box shell, a power-connected metal sheet and a conductive connector, wherein one end of the power-connected metal sheet is electrically connected to the conductive connector, and the other end of the power-connected metal sheet is electrically connected to the control circuit board through a power cord, and the control circuit board and the power cord are usually connected by welding or fixing with screws. However, the above scheme has the following disadvantages: due to the use of a power cord connection, the internal space of the power box is occupied, the production cost of the track light is increased and it is not conducive to reducing the volume of the power box. At the same time, during the assembly process, it is necessary to manually tighten the screws or use a welding gun for welding, which further increases the complexity of assembly, further increases the production cost of the track light, and is not conducive to the promotion of the track light power box.

[0034] like Figure 1 , Figure 2 and Figure 3 As shown, the embodiment of the utility model provides a track light power box, which includes: a power box housing 10, and a control circuit board 20 installed in the power box housing 10, a rotatable conductive connector 30 and a power-connecting metal sheet 40, wherein the conductive connector 30 can be rotatably extended out of the power box housing 10 to be electrically connected to the power-connecting track, one end of the power-connecting metal sheet 40 is electrically connected to the conductive connector 30, and the other end of the power-connecting metal sheet 40 is electrically connected to the control circuit board 20;

Since the abutting electrical spring piece 42 and the input pad 21 on the control circuit board 20 are directly electrically connected, the use of a power cord is avoided, thereby saving space in the power box housing 10 and reducing the production cost of the track light power box. At the same time, during the assembly process, the assembler avoids the operation of manually tightening screws or using a welding gun for welding, further reducing the complexity of assembly, further reducing the production cost of the track light power box, and facilitating the promotion of the track light power box.
