Abstract

The invention provides a parallel shielding antijamming cable. Through scientific and reasonable cable structure design and material type selection, the antijamming performance and operation safety of the cable are improved. The parallel shielding antijamming cable comprises two single parallelly arranged main power source lines, the space formed by the two single parallelly arranged main power source lines is coated with an oval or oval-like shielding layer, an isolation layer and a protection cover layer in sequence, the shielding layer is specifically a knitting shielding layer, the isolation layer is specifically a metal isolation shielding layer, the length of the long edge of the oval or oval-like shape is parallel to a connecting line of the centers of the two main power source lines, and the gap between the main power source lines in the cavity of the shielding layer is not provided with filler.

Description

technical field [0001] The invention relates to the technical field of cable structures, in particular to a parallel shielded anti-interference cable. Background technique [0002] At present, the charging cables used for power transmission and signal control in the charging system of new energy vehicles are in the initial stage in China, and the products mainly rely on imports. The drag installation performance and anti-interference ability are far from the technical level of similar foreign products, and are not qualified products in the true sense. [0003] The cables used in the charging system of new energy vehicles, because they need to have multiple functions such as power transmission, signal control and transmission, and need to have a large current carrying capacity, anti-electromagnetic interference, softness, and can be used under dragging conditions Therefore, it is necessary to carry out functional design in terms of integrated structure and anti-electromagnet...
