Embodiment Construction

[0016] Such as figure 1 As shown, tinned copper wires are twisted to form a conductor 1, a polyethylene insulating layer 2 is extruded on the conductor 1, a copper tape sub-shielding layer 3 is wrapped on the insulating layer 2, and an insulating layer 4 is set outside the sub-shielding layer to form a twisted pair core.

[0017] 3 pairs of twisted wire cores are twisted into a cable core, and a total shielding layer 5 is set outside the cable core, and the total shielding layer 5 is wrapped with a general isolation layer 6, and the total isolation layer 6 is extruded and wrapped with a PVC outer sheath 7 to form a computer. cable.

[0018] The sub-shield is copper tape.

[0019] The total shielding layer is aluminum foil, plastic film composite tape.

[0020] Compared with the prior art, the present invention has the following beneficial effects: First, the conductor is twisted with tinned copper wires, and the cable core is twisted with 2 or 3 paired wire cores, which mee...

Abstract

The invention discloses a structure of a cable, concretely relates to a cable for an electronic computer, belonging to the technical field of cable manufacturing. The cable for the electronic computer comprises a cable core and an outer sheath. The cable core is composed of twisted pair wire cores in an intertwisting way. A total shielding layer is arranged on the outside of the cable core. A total separating layer is arranged on the outside of the total shielding layer. The outer sheath is arranged on the outside of the total shielding layer. The twisted pair wire cores are provided with a polyethylene insulating layer on the conductor. A branch shielding layer is arranged on the insulating layer. A separating layer is arranged on a branch shielding layer. The outer sheath is the polyvinyl chloride sheath. The cable for the electronic computer is excellent in shielding effect, good in usage performance, wide in range of application and high in working temperature.

Description

technical field [0001] The invention discloses a cable structure, in particular relates to an electronic computer cable and belongs to the technical field of cable manufacturing. Background technique [0002] With the development of information technology, electronic computers have been widely used in various fields and industries in production and life. The performance of cables for electronic computers plays a vital role in the operation of electronic computers. However, the existing cables for electronic computers have poor shielding effect, low working temperature and narrow application range. Therefore, a new electronic computer cable is required. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a cable for electronic computer, which has excellent shielding effect, good performance, wide application range and high working temperature. [0004] In order to solve the above-mentioned technical problems, the e...
