[0031] In the power track of the utility model, after the live wire electrical connector 4, the ground wire electrical connector 5 and the neutral wire electrical connector 6 are introduced from the shell 1 into the inner shell 3, at least one of the live wire electrical connector 4, the ground wire electrical connector 5 and the neutral wire electrical connector 6 of the inner shell 3 is arranged inside the shell wall 31 of the inner shell 3, that is, at least one of the live wire electrical connector 4, the ground wire electrical connector 5 and the neutral wire electrical connector 6 is hidden in the shell wall 31 of the inner shell 3 and is not exposed, thereby reducing the complexity of wiring clutter and improving safety performance.

[0032] Preferably, the live wire electrical connector 4, the ground wire electrical connector 5 and the neutral wire electrical connector 6 are all arranged inside the shell wall 31 of the inner shell 3. In this solution, the live wire electrical connector 4, the ground wire electrical connector 5 and the neutral wire electrical connector 6 are hidden in the shell wall 31 of the inner shell 3 and are not exposed, which greatly reduces the complexity of wiring and improves safety performance.

[0033] Specifically, the live wire electrical connector 4, the ground wire electrical connector 5 and the neutral wire electrical connector 6 are injection molded inside the shell wall 31 of the inner shell 3. That is, in this solution, the live wire electrical connector 4, the ground wire electrical connector 5 and the neutral wire electrical connector 6 can be injection molded together in the shell wall 31 of the inner shell 3 when the inner shell 3 is injection molded. In order to facilitate processing and subsequent assembly, the overall live wire electrical connector 4, the ground wire electrical connector 5 and the neutral wire electrical connector 6 can be divided into two parts, one part is installed in the shell 1, and the other part is injection molded together in the shell wall 31 of the inner shell 3 when the inner shell 3 is injection molded, and the exposed connection end is reserved, and the connection end is connected to the live wire electrical connector 4, the ground wire electrical connector 5 and the neutral wire electrical connector 6 installed in the shell 1.

The housing 1 is provided with a socket 40 plug interface along the length direction, and the pins of the socket 40 are inserted into the plug interface, and the live wire pins, the ground wire pins and the neutral wire pins of the socket 40 are respectively in contact with the live wire electrical connector 4, the ground wire electrical connector 5 and the neutral wire electrical connector 6 in the housing 1, so as to realize the power connection of the socket 40, and the electrical appliance is plugged into the socket 40 to obtain power. The control unit 2 acts as an on-off switch to control the on and off of the live wire circuit, thereby controlling the power on and off of the power rail. The control unit 2 can use a common knob mechanical switch connected to the live wire circuit of the live wire electrical connector 4 to control the power rail, or it can control the power on and off of the power rail through other conventional controls, which will not be described in detail here.

[0035] In the inner shell 3, the minimum spacing between the live wire electrical connector 4 and the neutral wire electrical connector 6 is not less than 3mm. The minimum spacing between the live wire electrical connector 4 and the neutral wire electrical connector 6 in this solution is not less than 3mm, which can meet the safety regulations and ensure the safety performance of the power track.

Further, a resistor is provided on the first circuit board 7, and the resistor is electrically connected to the circuit of the neutral line electrical connector 6.
