Abstract

The invention discloses a grounding conductor limiting device of a screw type ground wire conductor clamp. The grounding conductor limiting device consists of an upper tongue clamping unit and a lower tongue clamping unit. For the upper tongue clamping unit, a top edge and a side edge are connected to form an L-shaped structure of the upper tongue clamping unit. The lower tongue clamping unit is formed by a main tongue plate and an auxiliary tongue plate; the main tongue plate is connected with the bottom end of the side edge of the upper tongue clamping unit by an upper rotating screw knob; and the auxiliary tongue plate is hinged with the main tongue plate by a hinge rod. Besides, a wire clamp limiter is also hinged to the hinge rod and includes two limit baffle plates arranged side by side; long sides and short sides form the L-shaped structures of the limit baffle plates; the long side bottoms are hinged with the hinge rod above the connection positions with the short sides; and the short side ends are connected by a cross beam. When a ground wire is hung, the wire clamp limiter prevents the grounded conductor from slipping. Under the effect of the upper rotating screw knob, the main tongue plate bounces upwardly to clamp the grounded conductor tightly. With the device, slipping of the conductor clamp and the grounded conductor during the ground wire hanging process can be effectively prevented; the operation efficiency is improved; and the power failure time is shortened.
