Abstract

The invention discloses a manufacturing method of a double-core composite sound equipment cable. The manufacturing method comprises the following steps: wrapping an insulating layer outside an electrified conductor; back-twisting and twisting the two sets of electrified conductors into a bundle to form an electrified conductor pair, wrapping the electrified conductor pair with a first middle sheath, and manufacturing a current transmission part; back twisting the two groups of optical fiber conductors to form an optical fiber conductor pair, and wrapping the bundled optical fiber conductor pair and the supporting piece with a second middle sheath to prepare an audio transmission part; and twisting the current transmission part and the audio transmission part into a bundle through back-twisting, and wrapping the bundle with an isolation layer and an outer sheath in sequence, so that the double-core composite sound equipment cable is manufactured. The independent current transmission part and the audio transmission part are arranged, electric signals and optical signals are transmitted at the same time, then the cable has the double functions of current transmission and audio transmission, excellent interlayer framework support is provided for the internal structure of the cable, and the mechanical property, the electrical property and the structural stability are improved.

Description

technical field [0001] The invention relates to the field of cable production, in particular to a method for manufacturing a double-core composite audio cable. Background technique [0002] With the improvement of people's quality of life, the supply of power and optical fiber transmission is becoming more and more tense, and the traditional cables have the following disadvantages: (1) only suitable for transmitting single signals such as electrical signals or optical signals; (2) simply connecting The wires and optical fibers are twisted together without a separate electromagnetic shielding structure; (3) only a single-layer sheath is provided outside the bundled wires and optical fibers to be suitable for indoor environment layout, which cannot meet the requirements of waterproof, acid and alkali resistance. , wear resistance, flame retardant, high and low temperature resistance, and UV resistance; (4) Use conventional braided wrapping methods to wrap the outside of the ca...
