It uses a special structure and material to reduce the contact resistance between the conductor and the grounding electrode through very high contact stress, and ultimately achieve the purpose of tension resistance. Pre-twisted tension clamps are widely used in the wiring and fixing of power lines. In the construction of power lines, a large number of steel wire ropes, conductors and other components are required, and the fixing of these components needs to reach a certain fixing force to ensure the stability and safe operation of the power lines. Pre-twisted tension clamps are an important tool for solving this problem. By using pre-twisted tension clamps, effective fixation and tension resistance of wires and other components can be achieved. The following problems exist in the prior art:

At the same time, the existing pre-twisted wire tension clamps are often made of smooth metal materials. When clamping the same smooth and multiple winding wires with larger diameters, the gaps between the wires are large, the clamps cannot be stably tightened, and the wires are prone to slipping and loosening.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] The metal soft plate 11 is wound around a plurality of combined wires, and then the front end of the metal soft plate 11 is inserted into and passed through the insertion hole 222 of the positioning box 221, and is continuously pulled forward until the wire is tightened to the point where it cannot be tightened any further, and then the adjusting knob 213 on the right side of the positioning adjustment box 211 is rotated to drive the adjusting threaded rod 212 in the inner cavity of the positioning adjustment box 211 to rotate, and the two positioning rods 215 can be driven to move to the left side through the through hole 216 by the threaded connection between the moving plate 214 and the adjusting threaded rod 212.

[0027] The following is a detailed description of the working principle of the pre-twisted conductor tension clamp.

[0028] like Figure 1-5 As shown, the metal soft plate 11 is wound around a plurality of combined wires, and then the front end of the metal soft plate 11 is inserted into and passed through the insertion hole 222 opened in the positioning box 221, and is continuously pulled forward until the wire is tightened to the point where it cannot be tightened any further, and then the adjusting knob 213 on the right side of the positioning adjustment box 211 is rotated to drive the adjusting threaded rod 212 in the inner cavity of the positioning adjustment box 211 to rotate, and the two positioning insertion rods 215 can be driven to move to the left side by the threaded connection between the movable plate 214 and the adjusting threaded rod 212, and then pass through the through hole 216 and then through the positioning docking hole 223 opened on the right side of the positioning box 221, so as to enter the insertion hole 222, and be inserted into the adjusting positioning hole 12 opened on the right side of the metal soft plate 11 for limited fixing. In order to improve the firmness of the fixation, the positioning rods 215 can be rotated to move to the left side, and then pass through the through hole 216 and then through the positioning docking hole 223 opened on the right side of the positioning box 221, so as to enter the insertion hole 222, and be inserted into the adjusting positioning hole 12 opened on the right side of the metal soft plate 11 for limited fixing. The lifting and lowering adjustment knob 226 above the positioning box 221 drives the lifting threaded rod 225 and the fastening pressure plate 227 at the bottom of the lifting threaded rod 225 to rotate and move downward, so that it moves downward from the pressure plate embedding groove 224, until the fastening pressure plate 227 uses the non-slip rubber pad 228 at the bottom to squeeze the top of the metal soft plate 11, and cooperates with the high friction resistance between the rubber material and the metal material to achieve secondary reinforcement of the metal soft plate 11 passing through the insertion hole 222 to prevent loosening.
