AI Technical Summary
When connecting existing industrial sockets and plugs, the connection relies on feel or experience to determine whether it is in place, which poses safety hazards such as poor contact, arcing, and accidental detachment due to improper connection. In addition, the existing indicator light method increases product cost and size.
The indicator, which employs a mechanical structure, includes a hinge, an extension, an indicator, and a trigger. The indicator is triggered to rotate by the mechanical action of the plug being inserted, and the insertion status is indicated by a viewing window, thus avoiding the need for additional indicator lights and electronic components.
It achieves accurate indication of plug-in status, ensures electrical safety, reduces material and assembly costs, and shrinks product size.
