Problems solved by technology

Generally, cables with two structures (one shielded type and one unshielded type) are designed for use. In this way, each cable has a sheath layer, which increases the cost of the cable. At the same time, the laying of the two cables also requires more more space and manpower

Abstract

The invention relates to a combined control cable comprising a first conductor. A first insulating layer is arranged outside the first conductor; a first metal shielding layer is arranged outside the first insulating layer; and the first conductor, the first insulating layer, and the first metal shielding layer form a shielding wire core unit. A second metal shielding layer is arranged outside the shielding wire core unit; an inner sheath is arranged outside the second metal shielding layer; and non-shielding wire core units are arranged outside the inner sheath uniformly, wherein the adjacent non-shielding wire core units are close to each other tightly. The non-shielding wire core units include second conductors; second insulating layers are arranged outside the second conductors; and the non-shielding wire core units form a non-shielding wire core layer. According to the combined control cable, the shielded wire core and the non-shielding wire cores are combined into one cable structure, so that the structure becomes compact and the manufacturing cost is low.

Description

technical field [0001] The invention relates to a cable, in particular to a control cable. Background technique [0002] The control cable is mainly used to transmit signals. In some cases, it is also necessary to prevent external interference on the signal transmission process. Therefore, a shielding layer is added outside the core, so that the core of the cable is divided into unshielded control core and shielded control core. Core. Generally, cables with two structures (one shielded type and one unshielded type) are designed for use. In this way, each cable has a sheath layer, which increases the cost of the cable. At the same time, the laying of the two cables also requires more More space and manpower. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the deficiencies in the prior art and provide a combined control cable with a compact structure and low manufacturing cost, which combines shielded cores and unshi...
