The invention relates to a guide rail strip comprising a guide rail module and a socket module. The guide rail module comprises a track, a power supply circuit and a control box. The socket module comprises a base, a displacement mechanism, an electrical connection mechanism for electrically connecting with a plug and three pins respectively corresponding to each conductive strip. The track is provided with strip-shaped slots along the length direction. There are two strip-shaped slots, wherein the two conductive strips are respectively installed on the two sides of one of the strip-shaped slots opposite to the track length direction, and the other conductive strip is installed on one side of the other strip slot opposite to the track length direction. The base is provided with two insertion parts respectively matched with the strip-shaped slots in an insertion way. The displacement mechanism drives each pin to move relative to the base and each pin is enabled to have a storage state of being stored in the insertion part located in the same strip-shaped slot and an unfolded state of moving outside the insertion part to contact with the corresponding conductive strip. With application of the scheme, the guide rail strip which reduces processing difficulty, increases device strength and improves electrical performance is provided.
