AI Technical Summary

Technical Problem

Existing shielded cables have insufficient shielding between stranded cores, making them prone to signal crosstalk, and their shielding performance against external signal interference is also inadequate.

Method used

It adopts a cross-shaped skeleton structure, with isolation walls and buffer grooves of different wall thicknesses, filling ropes and twisted core wires, and a combination of aluminum-plastic composite tape and tinned copper wire braided tape to form a gradient electromagnetic shield, which improves the internal anti-crosstalk performance. The combination of tinned copper wire braided tape and aluminum-plastic composite tape provides full-band electromagnetic shielding.

Benefits of technology

It improves the anti-crosstalk performance between stranded wires and the shielding effect against external electromagnetic interference, ensuring the stability and quality of signal transmission and reducing the impact of external electromagnetic interference.

Abstract

The utility model discloses a wire pair shielding type data transmission cable with high transmission performance, which comprises a cross framework, four isolation walls of the cross framework are different in wall thickness, buffer grooves are arranged at the tops of the isolation walls, crease grooves aligned with the bottoms of the buffer grooves are arranged on the outer side walls of the isolation walls, and the crease grooves are arranged at the bottoms of the buffer grooves. A filling rope and a group of twisted-pair core wires are arranged in a cavity between every two adjacent isolation walls, an aluminum-plastic composite belt is wrapped on the twisted-pair core wires, a tinned copper wire woven belt is woven on the cross-shaped framework, the tinned copper wire woven belt is in direct contact with the aluminum surface of the aluminum-plastic composite belt, and the tinned copper wire woven belt and the aluminum surface of the aluminum-plastic composite belt are wrapped on the cross-shaped framework. The tinned copper wire woven belt abuts against the twisted-pair core wire and extrudes the buffer groove, the groove wall of the buffer groove is extruded by the tinned copper wire woven belt and then is bent along the crease groove to be attached to the tinned copper wire woven belt, the tinned copper wire woven belt is wrapped with a wrapping belt, and the wrapping belt is wrapped with a sheath in an extruded mode. The cable is simple in structure, and has excellent signal shielding performance inside and outside.
