Embodiment Construction

[0039] Below in conjunction with example the present invention will be further described:

[0040] exist figure 1 Among them, a semi-conductive EVA plastic shielded flexible cable includes a copper core conductor 10, and the outer layer of the copper core conductor 10 is coated with a polyvinyl chloride insulating layer 20, an aluminum foil Mylar 30, a fiber braiding layer 40, an EVA plastic shielding layer 50 and The polyvinyl chloride outer sheath 60, these six parts are covered layer by layer from the inside to the outside. In practice, the copper core conductor is twisted with multiple annealed bare copper wires. The outer layer of the copper core conductor is covered with a polyvinyl chloride insulating layer to form a core wire. The core wire can be set to two cores or more than two cores to meet the needs of different purposes and occasions. The core wires need to be twisted when forming a cable.

[0041] In the present embodiment, semi-conductive EVA plastic pellet p...

Abstract

The invention relates to a flexible cable, in particular a semiconductive EVA plastic shielded flexible cable and a manufacturing method thereof. The cable comprises a copper core conductor (10), and is characterized in that the outer layer of the copper core conductor (10) is successively coated with a polrvinyl chloride insulating layer (20), an aluminium foil nylar (30), a fibrage layer (40), an EVA plastic shielding layer (50) and a polrvinyl chloride outer sheath (60), wherein the six parts are coated from inside to outside layer by layer. The invention adopts a new formula, and coordinates with the related process and manufacturing method to provide a new semiconductive EVA plastic shielded flexible cable which has good machining property, light weight, rounding and compact structure, excellent bending resistance, high strength of extension, excellent shielding property and long service life.

Description

technical field [0001] The invention relates to a flexible cable, in particular to a semiconductive EVA plastic shielded flexible cable and a manufacturing method thereof. Background technique [0002] In order to prevent electromagnetic wave interference in communication audio, broadcasting sound system, instrumentation electronic equipment, automation equipment and other anti-interference lines, the connection lines of these systems usually need to be shielded. [0003] For wires and cables, the most commonly used shielding materials are conductive materials such as copper wire, aluminum foil, and copper foil. The shielding structure includes wrapping or longitudinally wrapping the tape on the cable; winding or braiding the copper wire on the cable; and applying these methods to the cable in combination. The use of shielding tape requires less processing time and lower cost, but there are problems with shielding properties, bendability, and flexibility. Using copper wire...
