Problems solved by technology

The above two structures can meet the requirements of high elasticity and high wear resistance under the condition of suitable materials, but they cannot resist the interference of external electromagnetic waves, and there is mutual interference between the two pairs
In order to prevent interference, some cables have been adjusted in structure. After the insulating core is cabled, the shielding is braided, and finally the elastomer sheath is extruded. This structure not only has a large overall size, but the interference between the core pairs still exists; some cables For each pair of split screens, weave the total screen after the split screens. Although this structure can resist external electromagnetic wave interference and also eliminate the mutual interference between each pair, the structure is large in size, heavy in weight, and poor in elasticity and flexibility. , can not meet the laying of narrow space

Abstract

The invention discloses a cable. The cable comprises a shielding wire unit, an insulating wire unit, a ground wire (3), a sheath (4) and an outer shielding sleeve (5), wherein the sheath (4) is arranged on the outer shielding sleeve (5) in a sleeving mode, and the shielding wire unit, the insulating wire unit and the ground wire (3) are located in the outer shielding sleeve (5) and stranded mutually; the shielding wire unit comprises two wires stranded mutually and an inner shielding sleeve (6), and the wires are located in the inner shielding sleeve (6); the insulating wire unit comprises two wires stranded mutually. The cable is high in antijamming capability and can be applied to an environment with strong electromagnetic waves.

Description

technical field [0001] The invention relates to a cable with high elasticity and anti-interference. Background technique [0002] With the rapid development of electronic communication technology, the requirements for spring telephone cables for various electronic communication systems are getting higher and higher. Not only must they have high elasticity, high wear resistance and softness, but they should also be miniaturized and lightweight. , Anti-interference characteristics. The currently used telephone cables have four cores insulated and extruded elastomeric sheaths; there are also two pairs of conductors twisted after insulation and then extruded elastomeric sheaths. The above two structures can meet the requirements of high elasticity and high wear resistance when the material is suitable, but they cannot resist the interference of external electromagnetic waves, and there is mutual interference between the two pairs. In order to prevent interference, some cables ...
