[0002] With the rapid development of modern society, electricity, as a vital energy source, has been widely used in various fields. As a key carrier of power transmission, the use and importance of power cables are increasing day by day. Whether in the urban power grid system, industrial production base, or power facilities in remote areas, a large number of power cables are indispensable to realize the transmission and distribution of electric energy.

[0003] In the actual laying and use of power cables, due to the limitations of length, path and other factors, it is inevitable to connect them, which makes the cable joint a key part of the power transmission system. The existing cable joint welding lacks auxiliary tools, which will reduce the work efficiency of the staff, and seriously cause deviations during welding, resulting in unqualified cable connections. It is necessary to fix the two cables during welding, and the two cable joints need to be butt-jointed. Therefore, a welding connection device for power cable joints is proposed.

[0008] As a further improvement of the present technical solution, the two arc-shaped clamping grooves correspond to the inner arcs of the two arc-shaped extrusion plates. When the arc-shaped extrusion plates extrude and fix the cable connector, the arc-shaped extrusion plates are rotated between the two extrusion strips so that the inner side of the arc-shaped extrusion plates fits the cable connector.

The extrusion bar 32 can be supported by the support bar 31, and the middle position of one side of the extrusion bar 32 rotates on the support bar 31. An arc-shaped extrusion plate 33 is rotatably connected between each two groups of extrusion bars 32. The arc-shaped extrusion plate 33 rotates between the two extrusion bars 32, so that the arc-shaped extrusion plate 33 can be more closely attached to the outer side of the cable, thereby improving the fixing effect. The arc-shaped extrusion plate 33 is close to one end of the two extrusion bars 32, and one side of the extrusion bar 32 is rotatably connected to the rotation bar 34 near the other end. The rotation bar 34 squeezes the extrusion bar 32, so that the extrusion bar 32 rotates on the support bar 31, and the two extrusion bars 32 squeeze and fix the cable joint in the arc-shaped clamping groove 2, so that the staff can weld the two cable joints conveniently.

[0021] A driving bar 35 is provided on each two groups of rotating bars 34, and one side of the driving bar 35 is rotatably connected to the two rotating bars 34 near two positions. The two ends of the driving bar 35 rotate on the two rotating bars 34, so that the driving bar 35 can rotate the two rotating bars 34 when squeezing the two rotating bars 34. A U-shaped plate 36 is fixedly connected to the middle position of the bottom side of the two driving bars 35, and the two driving bars 35 are driven to move vertically by the U-shaped plate 36. The driving bar 35 squeezes the two rotating bars 34, so that the rotating bars 34 rotate the extrusion bars 32 on the supporting bar 31.
