Description

Technical Field

[0001] The utility model relates to the technical field of preformed insulation wire clamps, and particularly relates to a preformed insulation wire clamp. Background Technique

[0002] The preformed insulation wire clamp, also known as the preformed conductor tension clamp, is a kind of electrical fitting with strong tensile force and simple operation. It is mainly used for bare conductors and overhead insulated conductors of main and branch distribution lines to replace traditional bolt-type tension clamps. The preformed insulation wire clamp is widely used in fields such as electric power and communication. Especially in overhead lines that require high tensile force and high insulation performance. With the development of technology and the deepening of application, the preformed insulation wire clamp has gradually expanded to new application scenarios such as backup wire clamps for three-span sections.

[0003] The prior art patent document with the publication number CN202167813U provides a preformed tension clamp. The preformed tension clamp of this device is connected to the insulated conductor through preformed wires. The preformed wires are wound around the insulated conductor, increasing the stress-bearing area of the insulated conductor and distributing evenly without obvious stress concentration. The preformed wires are made of metal materials, and the elastic deformation of the metal materials is used to ensure that the grip force of the preformed tension clamp on the insulated conductor never disappears, and there will be no hidden danger of loosening in bolt connections. The emery inside the preformed wires increases the friction force between the preformed wires and the insulated conductor, ensuring the grip force of the preformed tension clamp on the insulated conductor.

[0004] However, the twisted wires in the preformed insulation wire clamp in the prior art generally do not have the function of adjusting the tension. And if the twisted wires become loose, the twisted wires cannot be further adjusted, thereby reducing the practicability of the preformed insulation wire clamp. Therefore, we need a preformed insulation wire clamp. Summary of the Utility Model

[0024] In a further preferred embodiment of the present invention, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the stranded wire assembly 5 includes a mounting post 501. The connecting piece 4 and the connecting rod 3 form a suspension structure through the mounting post 501, and one end of the connecting rod 3 is suspended outside the mounting post 501, strengthening the connection effect between the connecting piece 4 and the mounting post 501.

The stranded wire 505 winds around the outside of the wire, strengthening the connection effect between the connecting piece 4 and the stranded wire 505. The connecting piece 4 can rely on the stranded wire 505 to wind around the outside of the wire. When the hollow tube formed by the two legs of the stranded wire winds around the wire, a very strong clamping force can be generated to ensure a tight connection between the wire and the wire clamp, making the overall wire have a stronger load-bearing capacity. The connecting piece 4 and the stranded wire 505 form a suspension structure through the fixing bolt 502, and one end of the fixing bolt 502 passes through the stranded wire 505 and is connected to the inner wall of the nut 503, facilitating the setting of the fixing bolt 502.

In addition, after installation, the arranged stranded wire 505 can wind around the outside of the wire, strengthening the connection effect between the wire and the stranded wire 505. After installation, when the hollow tube formed by the two legs of the stranded wire winds around the wire, a very strong clamping force can be generated to ensure a tight connection between the wire and the wire clamp, making the overall wire have a stronger load-bearing capacity.

[0025] Working principle: When installing the twisted wire 505, one end of the twisted wire 505 can be placed inside the connecting piece 4, and the fixing bolt 502 can penetrate through the connecting piece 4 and the twisted wire 505.

In addition, after installation, the provided twisted wire 505 can be wound around the outside of the wire, and the connection effect between the wire and the twisted wire 505 can be strengthened. In addition, after installation, when the hollow tube formed by the two legs of the twisted wire is wound around the wire, a very strong clamping force can be generated to ensure a tight connection between the wire and the wire clamp, making the overall wire have a stronger bearing capacity. In addition, after installation, if the twisted wire 505 becomes loose, the adjusting disc 201 can be rotated, which can drive the screw rod 202 to rotate. The screw rod 202 can rotate in the screw groove 204 inside the moving plate 203, and the moving plate 203 can slide along the outer wall of the sliding rod 206 depending on the internal sliding groove 205. The moving plate 203 can drive the connecting rod 3 to move, and the connecting rod 3 can drive the connecting piece 4 to pull and drive the twisted wire 505 to adjust and move. At the same time, after adjustment, the moving plate 203 can be fixed by the bolt on the moving plate 203, so that the twisted wire 505 can be tightened for the fastening and installation of the wire.
