Layered longitudinal wrapping paper flat cable and manufacturing method thereof

Abstract

The invention relates to a layered longitudinal wrapping paper flat cable and a manufacturing method thereof, and belongs to the technical field of cable manufacturing. According to the technical scheme, a ground wire conductor (4) is longitudinally wrapped with a first paper tape (5) at a ground wire longitudinal wrapping mold (116) to form a ground wire, the ground wire is located between two main line insulation wire cores (2), the two main line insulation wire cores (2) and the ground wire are arranged in parallel to form a cable core, the two main line insulation wire cores (2) and the ground wire jointly enter an overall longitudinal wrapping mold (117) and then integrally and longitudinally wrap a second paper tape (6), and then the cable core enters a tape pressing device to be pressed and finally, directly enter an extruder (12) to extrude the PVC sheath (7). The flat cable has the positive effects that 1, the flat cable with the double-layer longitudinal wrapping paper structure is designed, compared with a common sheath multi-core cable, longitudinal wrapping cable paper is better stripped, the cost is lower, and the flat cable has very high economic advantages; and 2, a layered longitudinal wrapping device is designed and can be mounted in front of an extruder, a sheath is directly extruded after a paper tape is longitudinally wrapped and compressed, and redundant production procedures are reduced;.

Description

technical field [0001] The invention relates to a layered longitudinally wrapped paper flat cable and a manufacturing method thereof, belonging to the technical field of cable manufacturing. Background technique [0002] Fixed laying wires are mainly used in home decoration wiring and electrical equipment, and are the most common type of cables in the current society. There are two standards in my country that regulate such products, namely the national standard GB / T5023-2008 and the Ministry of Machinery standard JB / T8734-2016. Among them, GB / T5023-2008 mainly refers to the international standard IEC60227, while JB / T8734-2016 is the addition of some models and specifications not included in GB / T5023 by the Ministry of Machinery according to the actual situation in China. The cables listed in these two standards are classified as to CCC products. [0003] Although CCC products have covered most of the common cable models in the market, some of them still need to be customi...

Problems solved by technology

Among them, for the sheathed wires, RVV cables are more commonly used, while BVV cables are hard to see. The main reason is that there is a layer of inner sheath outside the insulation of BVV cables, which is inconvenient to strip and more expensive. few people use
