Compression-resistant polymer electromagnetic shielding cable

Abstract

The invention relates to the technical field of cables, and further discloses a compression-resistant polymer electromagnetic shielding cable. The cable comprises an outer protective sleeve, a bufferlayer is fixedly sleeved with the outer protective sleeve, a copper wire braided shielding layer is fixedly sleeved with the buffer layer, an air cushion sleeve is fixedly sleeved with the copper wirebraided shielding layer, an inner protective sleeve is fixedly sleeved with the air cushion sleeve, and a fixing strip is fixedly sleeved with the inner protective sleeve. According to the compression-resistant polymer electromagnetic shielding cable, the outer protective sleeve, the buffer layer, the copper wire braided shielding layer and the air cushion sleeve are matched with one another, thestrength of the electromagnetic shielding cable can be improved, the electromagnetic shielding cable can be effectively protected, springs in the buffer layer can counteract impact force borne by theelectromagnetic shielding cable in the transportation or use process, the service life of the electromagnetic shielding cable is prolonged, and the practicability of the electromagnetic shielding cable is improved.

Description

technical field [0001] The invention relates to the technical field of cables, in particular to a pressure-resistant polymer electromagnetic shielding cable. Background technique [0002] Cable is a general term for optical cables, cables and other items. Cables have many uses and are common and indispensable in daily life. Compression-resistant polymer electromagnetic shielding cables are more commonly used in signal transmission in the electronics industry. wire. [0003] Most of the existing cable protective sleeves are made of plastic and rubber organic polymers, which cannot protect the cables well. When used in some harsh environments, the protection of the core is not enough, especially under the pressure of the outside world. When the wire core of the cable is easily damaged, and the multiple signal transmission lines of the existing cable are placed together, the cables are easily rubbed against each other, which will cause damage to the cable sheath and affect the...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a pressure-resistant polymer electromagnetic shielding cable, which has the advantages of high protection and wear resistance, and solves the problem that most of the existing cable protective sleeves use plastic and rubber organic polymers. Composition, the cable cannot be well protected. When used in some harsh environments, the protection of the core is not enough, especially when it is under external pressure, it is easy to damage the core of the cable, and the existing cable If multiple signal transmission lines are placed together, the cables will easily rub against each other, which will cause damage to the cable sheath and affect the insulation effect of the cable, thus affecting the service life of the electromagnetic shielding cable and reducing the electromagnetic shielding cable.
