Embodiment 1

[0022] Embodiment 1: Low-frequency electromagnetic wave interference shielding form (such as figure 1 Show)

[0023] The shielding method of flexible and flexible cables uses copper foil braided shielding layer 4 to cope with the interference of low-frequency electromagnetic waves. Type 6 stranded conductors can be placed longitudinally on the inner side of the copper foil wire braided shielding layer as the supplementary conductor 3 of the shielding layer (that is, the drain wire, optional), and the 6 types of stranded conductors have good electrical contact with the shielding layer.

[0024] Corresponding to low-frequency electromagnetic wave interference, the extra-flexible cable adopts the form of braided copper foil wire shielding, and the copper foil wire structure is as follows: image 3 As shown, the copper foil wire is made of high-strength bulletproof wire wound with copper foil. Because of its light weight, softness, high tensile strength, and not easy to break, it...

Embodiment 2

[0026] Embodiment 2: broadband (0.001-5MHz) electromagnetic interference shielding form (such as figure 2 Show)

[0027] In the shielding method of flexible and flexible cables, the composite shielding form combining the circular tube shielding layer 2 and the braided copper foil wire shielding layer 4 is used to cope with the interference of broadband electromagnetic waves.

[0028] Copper foil wire is formed by winding copper foil 6 on the outer layer of high-strength bulletproof wire 5, and there are 6 types of stranded conductors longitudinally placed inside the copper foil wire braided shielding layer as the supplementary conductor 3 of the shielding layer, and 6 types of stranded conductors Make good electrical contact with the shield.

[0029] The round tube shielding layer 2 is placed between the cable core 1 and the braided copper foil shielding layer, and the round tube shielding layer is made of extruded conductive elastomer.

[0030] The surface resistance of th...

Abstract

The invention discloses a deflection-resisting super flexible cable shielding method, which belongs to the technical field of cables. A copper foil wire woven shielding layer is adopted for electromagnetic wave interference correspondingly, and the copper foil wire is formed by winding high-strength bulletproof wire with copper foil. An equipment connection cable designed by the invention has deflection-resisting and super flexible characteristics, the problem that the traditional cable can not pass a long-time deflection-resisting test due to limitation of the shielding form, the service life of the product is effectively improved, a super low cable use bending radius can be kept, the method can be widely applied to signal transmission by an industrial automatic device, such as a towline cable, and an imported product can be replaced.

Description

technical field [0001] The invention relates to a shielding method for cables, in particular to a shielding method for ultra-flexible cables, which belongs to the technical field of cables. Background technique [0002] The shielding layer of the equipment cable mainly has the form of coated metal foil tape (copper, aluminum, metal polyester composite), winding metal wire, braided metal wire, etc., which are mainly used to shield the interference of external electromagnetic waves on the cable body or itself to the outside world. So as to ensure the authenticity and reliability of signal transmission. [0003] In order to adapt to the development requirements of intelligent equipment, twist-resistant and extra-flexible cables have become the main types of equipment cables. However, the shielding form of existing equipment cables is difficult to meet the requirements of twist-resistant and extra-flexible. The shielding layer usually uses braided metal wires. Although the cabl...
