Embodiment Construction

[0023] It can be seen from the background technology that the existing cables are poor in disturbability and easy to be damaged; the inventor initially determined that the reason for the deformation of the cable is that the cable will inevitably produce various types of deformation during the production and processing process. Bending under normal conditions, various bendings cause uneven force and different tightness between the cores, resulting in uneven distribution of internal stress in the insulated cores of the finished cable, and repeated bending of the conductors into "Z" " or "Ω" type, the shielding layer of the wire escapes and is worn out by other shielding layers, forming a short circuit. Since the tensile or compressive deformation of the cable is gradually generated with time or the number of bendings, the deformation is gradually accumulated. Therefore, the degree of harm caused by bending should not be controlled, and the timing of short circuit should not be g...

Abstract

The invention discloses a flat cable and a manufacturing method thereof. The flat cable provided by the invention includes: a flat wire harness, an electrical connector and a bracket. The flat wire harness includes: at least two wire bundles, and the wire bundles are separated according to One" type binding; the wire bundle is covered with polytetrafluoroethylene film; the outer surface of the flat wire bundle is wrapped with a glass fiber sleeve. The durability of the cable can be improved by means of the invention.

Description

technical field [0001] The invention relates to the technical field of cables for aerospace products, in particular to a flat cable manufacturing process technology to meet the miniaturization and high reliability requirements of the outer cabin cables of aerospace products. Background technique [0002] With the rapid development of aerospace technology, the performance of the product has been greatly improved. The area of ​​the external cable laid on the surface of the product directly affects the aerodynamic shape index of the product, and the aerodynamic shape index directly affects the flight performance of the product. The products transmit a variety of signals, including power signals, high-frequency signals, low-frequency signals, and different currents. Therefore, there are many types of cables, and the cables outside the cabin must have requirements such as high temperature resistance and high reliability. Due to the complex requirements, the cables produced in the...
