DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0021] Referring to Figures 1-5, The copper-clad steel stranded wire connection device includes a connection cylinder 1 and a relay block 101. The relay block 101 is provided with connection cylinders 1 on both sides. The inner wall of the connection cylinder 1 is threadedly connected with a threaded joint 5. One end of the threaded joint 5 is provided with a plurality of rotation grooves 51. One side of each rotation groove 51 is rotatably installed with an arc-shaped clamping plate 2 through a rotating seat 7. Each arc-shaped clamping plate 2 forms a cylinder, and the arc-shaped clamping plate 2 is limit-installed inside the connection cylinder 1.

[0022] Furthermore, a conductor block 6 is installed in the middle of the relay block 101. The conductor block 6 is used to guide and connect multiple copper-clad steel stranded wires.

[0023] Furthermore, the outer side of the threaded joint 5 is provided with threads, and the threaded joint 5 is screwed with a threaded wall 8 opened on the inner wall of the connection cylinder 1 through the threads.

[0024] Furthermore, raised screw hole connection blocks 3 are provided at both ends of one side of the arc-shaped clamping plate 2, and the screw hole connection blocks 3 on each arc-shaped clamping plate 2 correspond and fit with each other. A threaded hole is opened in the middle of the screw hole connection block 3 to install a fastener.

[0025] Furthermore, a plurality of friction blocks 4 are arranged on the inner wall of the arc-shaped clamping plate 2.

[0026] Furthermore, a rotating seat 7 is provided in the middle of one side of the arc-shaped clamping plate 2. Both ends of the rotating seat 7 are installed with rotating shafts 7. Both ends of the rotating shafts 7 are rotatably installed in the rotation grooves 51, and a torsion spring 9 is arranged at the rotation connection between the rotating shafts 7 and the rotation grooves 51.

[0027] In this embodiment, the multiple arc-shaped clamping plates 2 arranged inside the connection cylinder 1 are rotated and extended outwards. Under the rotation action of the torsion spring 9, the arc-shaped clamping plates 2 are gradually unfolded outwards until the threaded joint 5 inside the connection cylinder 1 completely moves to the outer edge of the connection cylinder 1. The arc-shaped clamping plates 2 are completely unfolded outwards and form a kind of bell mouth. At this time, the two copper-clad steel stranded wires to be connected are respectively passed through the middle of the arc-shaped clamping plates 2 and inserted into the connection cylinder 1 for installation.

[0028] Then, appropriately close each arc-shaped splint 2 to make it close inward and squeeze the outer wall of the wire body. At this time, push the arc-shaped splint 2 inward to drive the threaded joint 5 connected thereto to move into the connecting cylinder 1 until the threaded joint 5 contacts the threaded wall 8 provided on the inner wall of the connecting cylinder 1. At this time, drive the threaded joint 5 to rotate through the arc-shaped splint 2, and drive the arc-shaped splint 2 and the threaded joint 5 as a whole to further retract into the connecting cylinder 1 by threadedly connecting with the threaded wall 8. At this time, the arc-shaped splint 2 is completely closed into a cylinder, and the friction block 4 provided inside is in full and sufficient pressing contact with the outer wall of the wire body. At this time, insert a fastener into the screw hole connection block 3 provided on the outside of the arc-shaped splint 2 to lock two adjacent arc-shaped splints 2. At this time, the cylinder formed by the arc-shaped splint 2 is completely embedded in the connecting cylinder 1, and the wire body is firmly locked inside the connecting cylinder 1 under the clamping action of the arc-shaped splint 2 and the friction block 4, and a conductor block 6 for connection is provided inside the connecting cylinder 1 to realize the connection of the wire bodies on both sides.

[0029] Among them, it is worth noting that when the arc-shaped splint 2 rotates together with the threaded joint 5, the friction block 4 inside it will contact the wire body. Whether or not it drives the wire body to rotate together does not affect the normal use and connection.

[0030] In the present utility model, by inserting two copper-clad steel stranded wires to be connected into the connecting cylinders 1 at both ends of the relay block 101, synchronously closing multiple arc-shaped splints 2 and rotating the splints to drive the threaded joints 5 inside to rotate, the threaded joints 5 rotate and drive the arc-shaped splints 2 to retract through thread rotation, so that the multiple arc-shaped splints 2 gradually contract and close, and squeeze the outer wall of the wire body. At the same time, when the arc-shaped splints 2 are completely embedded in the connecting cylinder, lock the arc-shaped splints 2 through fasteners. The connection process is convenient and can be completed without using additional accessories. It is not only firmly connected but also convenient to operate, effectively improving the operation efficiency.

[0031] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
