The invention provides an insulation protection terminal for a low voltage lead. The insulation protection terminal for the low voltage lead comprises a foundation, a pressure member, a cover board and a spring, wherein the foundation is a hollow cuboid structure having an opening at a side surface, a relatively narrow side wall of the foundation is provided with a lead hole, an internal portion of the foundation just opposite to the lead hole is provided with a fixed channel, the pressure member comprises a lead channel and a pressure board arranged on the lead channel, the lead channel and the lead hole are parallel with each other, an internal portion of the foundation below the pressure member is provided with a spring cylinder, the spring is fixed on the spring cylinder, and the cover board is fixed on a screw hole at a side surface of the foundation through a screw. The insulation protection terminal can be fixed on a guide rail type wiring terminal, and isolation and recovery work of a live-line lead can be rapidly and safely accomplished.
