Cable dividing device with anti-turning function and arranged on cable stranding machine

Abstract

The invention discloses a cable dividing device with an anti-turning function and arranged on a cable stranding machine. The cable dividing device is characterized by being arranged in the shape of a hollow cone frustum 1, the peripheral face of the cone frustum 1 is smooth, a cable dividing plate 2 is arranged at the table face end of the cone frustum 1, a center hole 21 is arranged at the center of the cable dividing plate 2, a plurality of core wire through holes 22 are arranged on the periphery of the center hole 21, a hollow shaft rod 3 is arranged at the center of the hollow cone frustum 1, the center axis of the hollow shaft rod 3 is overlapped with the center axis of the hollow cone frustum 1, and one end of the hollow shaft rod 3 is fixed in the center hole 21 of the cable dividing plate 2. The cable dividing device has the advantage that contact area of a signal wire group and the conical face is greatly increased in the cabling process, and friction resistance is increased to enable the signal wire group not to be turned with axial torsion and guarantee that relative position between the signal wire group is stable. Cabled signal cables are good in appearance rounding degree, and electric performance of the signal cables is greatly improved. Simultaneously, the cable dividing device is suitable for being used in the cabling process of power cables.

Description

Technical field: [0001] The present invention relates to cable-forming equipment for signal cables, in particular to a wire-distributing device on a cage stranding machine used for forming signal cables, in particular to a wire-distributing device with an anti-turnover function on the cage stranding machine. Background technique: [0002] This device in the prior art is designed to prevent the signal line group of parallel structure from continuously turning over under the action of axial torsion when the cage stranding machine is cabled. Using the tapered surface of the device to increase the contact area between the parallel wire group and the cone can effectively prevent the signal wire group from turning over, improve the roundness of twisting, and avoid the high frequency caused by the continuous turning and mutual extrusion of each group of signal wires. Poor electrical performance. [0003] The signal cable is formed after going through the cable forming process on t...

AI Technical Summary

Problems solved by technology

The flipping of the signal lines will make the relative position of each group of signal lines not fixed, and will cause mutual extrusion, and the mutual extrusion will cause the core wires in the signal line group to be damaged to varying degrees, resulting in signal transmission performance degradation

[0004] During the cable forming process of the existing signal cables on the cage stranding machine, multiple sets of signal wires pass through the distribution tray and then enter the eye mold to gather and gather into cables. Most of the distribution trays on the existing cage stranding machine are band-pass The traditional distribution board with holes, the distribution board of this structure is only suitable for the cabling requirements of power cables, but it is not suitable for signal cables. For this reason, the inventor of the applicant unit improved the traditional distribution board into After a period of trial use, the distribution plate with disc structure is not very effective. The main reason is that the contact area between the signal line group and the line distribution plate is small, and the signal line group will produce the same signal line under the action of axial torque. Inverted in the opposite direction, the relative position between the signal wire groups is unstable, and there will be a phenomenon of mutual extrusion and damage to the inner core wire, which will eventually lead to poor roundness of the cable appearance and serious damage to the electrical performance
