Description

Technical Field

[0001] The utility model relates to the technical field of track switches, in particular to a track switch combination structure. Background Art

[0002] Track sockets are a new type of socket product, primarily consisting of a power track and an adapter. Power tracks, also known as power rails, are typically installed on walls, tables, and baseboards. The adapter is mounted on the track and draws power from it. The adapter has a jack for plugging in devices. Because the number of adapters installed on the track can be increased or decreased based on demand, and their position on the track can be adjusted at will, they have become very popular in the market.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN221407902U, which discloses an electric track mounting structure, relating to the technical field of track sockets, and includes a track body, a first magnetic member, and a second magnetic member; the first magnetic member is mounted on the track body, the second magnetic member is mounted on the mounting surface, and the first magnetic member and the second magnetic member are magnetically fixed. This application installs the first magnetic member on the track body and the second magnetic member on the mounting surface. When the track body is mounted on the mounting surface, it is only necessary to place the track body on the mounting surface. At this time, the first magnetic member and the second magnetic member attract each other to achieve fixed installation of the track body on the mounting surface; the track body is adsorbed on the mounting surface by magnetic force, which facilitates the fixed installation of the track body on the mounting surface and improves the problem of inconvenient installation and disassembly of the track body on the mounting surface.

[0004] Existing track switches generally connect the neutral wire and the live wire through a metal slide rail, and the electrodes of the socket are embedded in the slide rail to ensure circuit connectivity while moving the socket. This method may cause wear between the slide rail and the electrode after sliding the socket multiple times, resulting in contact breakage. At the same time, the installation angle will cause the gravity of the socket to affect the contact state between the electrode and the slide rail. Utility Model Content
