In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0044] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] Referring to Figures 1 to 13 As shown in FIG. 1, a quick-mounting power rail comprises a power rail box 1, a busbar group 2 and a terminal block 3; the power rail box 1 has a receiving cavity 10 inside, the receiving face 11 of the power rail box 1 has a long strip-shaped guide groove 12 for inserting the power taking body of an adapter, the guide groove 12 penetrates through the receiving face 11 of the power rail box 1 and communicates with the receiving cavity 10; the busbar group 2 comprises at least two mutually spaced busbars 20, and each busbar 20 is identical, the busbar 20 is connected with the inner wall of the receiving cavity 10, and the length direction is the same as that of the guide groove 12; at least one end of the power rail box 1 is provided with a mounting port 13, the terminal block 3 is movably arranged in the mounting port 13, and the terminal block 3 is provided with a terminal 4 electrically connected with the busbar 20.

[0046] The power rail provided by the embodiment is used to supply power to the adapter. The socket face 11 of the power rail box 1 (a face used to plug or dock with the adapter) has a guide groove 12, and the guide groove 12 is in communication with the accommodating cavity 10 inside the power rail box 1. Therefore, the power taking body of the adapter can be plugged into the accommodating cavity 10 through the guide groove 12 and contact the busbar 20 in the accommodating cavity 10 to take power. In addition, the guide groove 12 is long strip-shaped, and the length direction of the busbar 20 is the same as the length direction of the guide groove 12. Therefore, the power taking body plugged into the guide groove 12 can move along the length direction of the guide groove 12 while ensuring contact with the busbar 20, until it moves to a suitable position according to the user's demand. In this way, the flexibility of the rail socket is improved.

[0047] In addition, since the busbars 20 in the power rail are the same, the universality of the parts is improved, and the manufacturing cost of the rail socket is effectively reduced.

[0048] In the embodiment, the power rail can be applied to both two-pin adapters (adapters with two pins) and three-pin adapters (adapters with three pins). When the power rail is applied to a two-pin adapter, the busbar group 2 includes two busbars 20, and the two busbars 20 are respectively arranged on the inner walls of the accommodating cavities 10. More specifically, the two busbars 20 are respectively a live wire busbar and a zero line busbar, and the live wire busbar and the zero line busbar are arranged on the same side of the guide groove 12. When the rail socket is applied to a three-pin adapter, the busbar group 2 includes three busbars 20, two of which are respectively arranged on the inner walls of the guide groove 12 on the same side, and the other busbar is arranged on the side opposite to the guide groove 12. In the vertical direction, the two busbars 20 arranged on the inner walls of the guide groove 12 are arranged in staggered manner, so that the creepage distance between the two busbars 20 is as large as possible in the limited space, so as to eliminate the safety hazard of power use.

[0049] Of course, in other embodiments, the positions of the busbars 20 in the accommodating cavities 10 can also be adjusted according to the adapters to be adapted, which is not limited in the embodiment.

[0050] In order to solve the problems of quick assembly, high installation efficiency and firm connection of the power rail, in the embodiment, the terminal block 3 includes a shell 30, a shell top surface 31 and a shell bottom surface 32 formed on the shell 30. The shell top surface 31 and the shell bottom surface 32 each have an inclined portion 33 and a horizontal portion 34. The vertical distance between the inclined portion 33 of the shell bottom surface 32 and the inclined portion 33 of the shell bottom surface 32 is slightly smaller than the vertical distance of the mounting port 13, and the vertical distance between the horizontal portion 34 of the shell top surface 31 and the horizontal portion 34 of the shell bottom surface 32 is slightly larger than the vertical distance of the mounting port 13, so that the terminal block 3 is inserted into the mounting port 13 and fastened with the power rail box 1.
