Problems solved by technology
In order to avoid single-wire misalignment during the stranding process of the star-stranded wire, ensure that the star-stranded wire has good symmetry, round structure, and stable electrical performance, a "ten"-shaped mold is generally installed on the sizing die part of the stranding cage during the stranding process. However, during the twisting process, due to the design defect of the "ten"-shaped wire splitter, the single wire shakes severely when the "ten"-shaped wire splitter is twisted, resulting in an unstable star stranded wire structure. "Ten" The glyph splitter is easy to wear and other problems
Due to the instability of the star stranded wire, it directly affects the capacitive coupling, unbalanced ground capacitance and crosstalk of the railway digital signal cable, which seriously affects the safety performance of the cable.

The invention provides a special splitter for railway digital signal cable star stranded wires, which includes a support body; wire slots are symmetrically arranged on the support body, and corresponding wire slots are provided on the support body for connecting with the wire slots. The positioning step for the matching of the card slot on the star winch. The supporting body is in the shape of a disk. The wire trough has a U-shaped structure. The supporting body is evenly arranged with 4 wire passing grooves along its circumferential direction. The invention can ensure that the single wire will not shake up and down in the U-shaped groove when the wire is twisted. It has the characteristics of high structural stability and good symmetry. Cable crosstalk, attenuation and other indicators, enhance the performance of mutual interference between core wires. In addition, the splitter has a simple structure, is easy to process, and has great practical value.
Description
technical field [0001] The invention belongs to the technical field of cable production and manufacturing, and in particular relates to a special splitter for railway digital signal cable star strands. Background technique [0002] In the production process of railway digital signal cables, high-speed star-stranded machines are generally used for twisting star-stranded wires. In order to avoid single-wire misalignment during the stranding process of the star-stranded wire, ensure that the star-stranded wire has good symmetry, round structure, and stable electrical performance, a "ten"-shaped mold is generally installed on the sizing die part of the stranding cage during the stranding process. However, during the twisting process, due to the design defect of the "ten"-shaped wire splitter, the single wire shakes severely when the "ten"-shaped wire splitter is twisted, resulting in an unstable star stranded wire structure. "Ten" The glyph-shaped splitter is easy to wear and t...
