Description

Technical Field

[0001] The utility model relates to the technical field of track sockets, in particular to a track socket with an anti-fool function. Background Art

[0002] The track socket generally includes a power track and an adapter. When installed and used, the power track is fixed on the wall or desktop and connected to the power cord. The adapter is installed on the power track to connect external devices. The adapter can be installed at any position along the length of the power track, which has better flexibility in use.

[0003] Most of the existing track sockets do not have anti-mistake structures on the power tracks and adapters. When the adapter is installed on the power track, the live wire and the neutral wire are easily connected reversely. If the live wire and the neutral wire are connected reversely, the electrical appliance may not work properly because the circuit cannot be closed and the electrical appliance cannot operate. It may also cause a short circuit and cause safety hazards. For electrical appliances with triangular plugs, if the position of the live and neutral wires is wrong, the switch of the appliance cannot disconnect the live wire, resulting in voltage still existing inside the appliance when the appliance is not working. Once the metal casing leaks electricity, there will be a risk of electric shock. Utility Model Content
