Problems solved by technology

However, due to the fact that both the outermost metal braided protective layer and the second outer metal braided shielding layer need to have a certain high strength, they are relatively thick, resulting in a relatively thick audio cable. In addition, the audio cable is greatly increased. Not to mention the high cost, it also makes the audio cable unfavorable for winding and handling, and it is also inconvenient when unfolded. For example, it is easy to arch (not stick to the ground) and not easy to entangle , is not easy to drag, etc., which affects the overall use effect, and after frequent bending, the metal braided protective layer is easy to be strained and cracked, which affects its service life

Embodiment 1

[0028] see Figures 1 to 5 , the preparation method of the highly flexible, wear-resistant and anti-interference audio cable provided by this embodiment includes the following steps:

[0029] 1) Divide the metal wire core into more than three strands to form three or more sets of metal wire core units, and then extrude each wire core unit respectively, and coat the core wire cladding layer to form more than three sets of core wire units. It should be noted here that the metal wire core may be a plurality of single copper wires, or may be a wire formed by twisting a plurality of copper wires one by one. All in all, according to the number of internal wire cores required by different functional audio cables, it is divided into more than three units to obtain more than three sets of core wire units (ie, more than three single core wires).

[0030] 2) Preheating and softening the core cladding layer of the core wire unit obtained in step 1), so that the outer surface of the wire ...

Embodiment 2

[0044] This embodiment is basically the same as the first embodiment, and the difference lies in:

[0045] In step 4), when the pre-impregnated wear-resistant fiber cloth is spirally wound and wrapped, it is in the form of intersecting the direction of the spirally wound groove grooves on the outside of the first core coil, and the wrapping is performed to form the second core. As for the coil coil, at this time, the outer side of the second core coil coil is smooth and smooth, but a spirally wound gap is formed between the impregnated wear-resistant fiber cloth and the impregnated basic fiber cloth. The wear-resistant fiber cloth coated and impregnated in this way, although the degree of bonding and integrity of the outer covering layer of the audio cable and the second core coil will be reduced, and the anti-pull performance will be slightly reduced; but its advantages are: , its softness and elastic reset effect will be greatly increased, so that it has good drag, bending a...

Abstract

The invention discloses a preparation method of a high-flexibility wear-resistant and anti-interference audio cable and an audio cable. The basic fiber cloth and the wear-resistant fiber cloth are pre-impregnated with resin bonding base materials, and are extruded, wound, twisted, Processes such as heating and bonding make the basic fiber cloth and the wear-resistant fiber cloth tightly combined in the audio cable to form a stable basic fiber cloth layer and a wear-resistant fiber cloth layer. Using the electromagnetic shielding performance and wear-resistant layer performance of the basic fiber cloth layer and the wear-resistant fiber cloth layer, without using a metal braid, the wear resistance and anti-interference effect of the audio cable can be ensured, and the cable is soft and durable. Repeated dragging, resistance to repeated bending, the overall effect is excellent.

Description

technical field [0001] The invention relates to the preparation of data cables, in particular to a preparation method of a highly flexible, wear-resistant, anti-interference audio cable and an audio cable. Background technique [0002] Audio cables, especially audio cables for outdoor performances, such as outdoor concerts, temporary stage construction in squares, etc., all require the use of temporarily laid audio cables. These audio cables connect the host and various audio devices. If it is not fixed, buried or worn, it will be continuously dragged, pulled, bent, stretched, rolled into a ball, etc. during the activity. As a result, the cable will continuously rub against the ground or lawn, etc., causing wear and tear and affecting the life of the cable. In addition, when used outdoors, due to the existence of many electronic devices such as mobile phones and signal base stations around, electromagnetic interference will be generated, which will affect the signal transmi...
