[0024] Example

[0025] like Figures 1 to 5 As shown, a new type of cast-free open cable joint includes a cable joint body 1, the upper end of which is connected with a left ear plate 2 and a right ear plate 3 relative to each other, and a pin shaft 4 is penetrated through the upper part of the left ear plate 2 and the right ear plate 3, and the cable joint body 1 is in a conical structure, and the cross-section of the cable joint body 1 of the conical structure is gradually reduced from top to bottom, and a connecting through hole 5 is opened at the central axis of the cable joint body 1, and the connecting through hole 5 is in a conical structure, and a spiral column 7 for clamping a steel wire rope 6 is connected in the connecting through hole 5 of the conical structure.

[0026] The spiral column 7 in the present invention is provided with a conical structure matching the connecting through hole 5, and the cross section of the spiral column 7 with the conical structure is gradually reduced from top to bottom.

[0027] The central axis of the spiral column 7 in the present invention is provided with a rope core through hole 72 for passing the rope core of the steel wire rope.

[0028] The spiral column 7 in the utility model is provided with a plurality of installation grooves 71 for accommodating the strands of the steel wire rope, wherein the plurality of installation grooves 71 are provided on the spiral column 7 in a spiral structure, and the installation grooves 71 are provided with anti-slip stripes, which can improve the firmness of the installation of the steel wire rope strands.
