Description

Technical Field

[0001] The utility model relates to the technical field of cable installation, and particularly relates to a tool for installing cables. Background Technique

[0002] The production of cable lugs for large cables with multi-strand copper wires has always been a difficult project for electrical workers, and there is no professional production tool at present. Generally, the method of directly threading the cable head manually is adopted. Most of the cable heads need to cut off some copper wires before they can be installed. This method affects the electrical conductivity of the line, has many burrs on the produced cable heads, and takes a long time. In the conventional installation of cable lugs, problems such as the divergence of the cut cable head copper wires, the increase in cross-sectional area, and the deformation of the cable cross-section make it impossible to directly thread the cable lug. The production time is relatively long. 6 large cable lugs can be produced in 8 hours. It is necessary to cut off some surrounding copper wires before the copper wire cable lug can be inserted, which easily affects the electrical conductivity of the line, has many burrs on the produced cable heads, and takes a long time. Content of the Utility Model

[0003] The purpose of the utility model is to provide a tool for installing cables. Through this tool, cables and cable joints can be conveniently installed, and the work efficiency can be effectively improved.

[0004] The technical solution adopted by the utility model is a tool for installing cables. This tool is applicable to the production of cable lugs with a specification of 25 mm² and above. It includes a tool body, which is divided into upper and lower parts. One end of the two parts of the tool body is hinged together, and the other end is connected by a vertically arranged fixing screw and a threaded hole. The center of the tool body has a circular through-hole, and the center line of the circular through-hole is perpendicular to the plane where the fixing screw is located. The diameter of the circular through-hole matches the actual measured value of the cable copper core.

[0005] The specific implementation method is as follows: 1. Select a cable lug production tool of the corresponding size, clamp the root part of the peeled cable (the root copper wires are not divergent or deformed), and tighten the fixing screw appropriately to maintain a certain pressure; 2. Tap the tool to slide to the cable head. This process can ensure that all the loose and deformed copper wires are tightened; 3. Tap the cable lug so that it slides towards the cable root together with the tool; 4. Unscrew the fastening fixing screw, remove the tool, and tap the cable lug to the cable root again to successfully complete the insertion of the cable lug. Since 2021, the utility model has been used in the electrical operations in the blast furnace area, which can greatly improve the production quality of large cable lugs. The produced cable heads do not need to cut off copper wires and have no burrs. The production efficiency is relatively high. 45 can be produced in 8 hours. This tool is simple to manufacture and convenient to use, and has a certain popularization in the same industry. Description of the Drawings

[0008] Figure 3 is a state diagram of the present utility model after the cable lug is installed. Specific embodiments

[0009] A tool for installing a cable, as shown in Figure 1 , 2 , 3. This tool is applicable to the production of cable lugs with a specification of 25 mm² or above. It includes a tool body 1, which is divided into upper and lower parts. One end of the two parts of the tool body is hinged together by a pin shaft 2, and the other end is connected by a vertically arranged fixing screw 3 and a threaded hole 5. The center of the tool body has a circular through hole 4, and the center line of the circular through hole 4 is perpendicular to the plane where the fixing screw 3 is located. The diameter of the circular through hole 4 matches the actual measured value of the cable copper core 6.

[0010] During use, the cable copper core 6 is clamped by the tool body 1 of the present utility model to prevent the cable copper core 6 from spreading. The cable joint 7 is struck with a hammer 8, so that the cable joint 7 pushes the tool body 1 to move backward relative to the cable copper core 6, thereby smoothly completing the socketing operation of the cable joint 7 and the cable copper core 6. After that, the tool body 1 is removed, and the cable joint 7 is continuously struck to completely cover the cable copper core 6.
