Embodiment Construction

[0018] Below in conjunction with accompanying drawing, illustrate in detail the specific content of the present invention:

[0019] Such as figure 1 The communication cable shown is mainly composed of a cable core formed by four wire pairs 1 arranged in parallel and a PVC sheath 2 covering the outer periphery of the cable core. Each wire pair 1 consists of two insulated single wires 11 at a certain knot Each single wire 11 is composed of a copper wire 111 and an HDPE insulating layer 112 wrapped around the copper wire 111 . The sheath 2 is flat, and its inner side closely fits the wire pairs 1 .

[0020] In order to optimize the performance of crosstalk, the twisted pitches of two adjacent wire pairs 1 are different. In this embodiment, in order to facilitate the arrangement of the twisted pitches, the twisted pitches of the four wire pairs are simplified into two types, such as figure 1 As shown, the four wire pairs 1 are in the direction from left to right, where the pitch...

Abstract

The invention relates to an indoor compressed cable for digital communication, which comprises a plurality of wire pairs and a sheath, in which the wire pairs are sheathed, wherein each wire pair comprises two stranded single wires, and each single wire consists of a copper wire and an insulating layer, in which the copper wire is sheathed; the wire pairs are arranged side by side into a layer; and the sheath is compressed, and the inner side of the sheath is in close fit with the wire pairs. By longitudinally arranging the wire pairs in a single-layered manner, the cable of the invention canincrease the interval distance of the wire pairs and increase the anti-crosstalk capacity; for the sheath of the cable is compressed, the cable is more applicable to indoor installation and particularly applicable to installation at wall corners and under carpets; and meanwhile, the cabling procedure of the cable is simpler, thus greatly improving the production efficiency.

Description

technical field [0001] The invention relates to a communication cable, in particular to a flat communication cable for indoor laying and a manufacturing method thereof. Background technique [0002] With the rapid development of computer technology and network applications, digital communication cables are widely used in intelligent buildings, computer local area networks and regional data exchange network systems, among which 4 pairs of UTP unshielded digital communication cables account for more than 50%. [0003] The existing 4 pairs of UTP unshielded digital communication cables are 4 pairs of twisted wires with different pitches twisted into a circular cable core in the S or Z direction, and a single-twisted or double-twisted cable forming machine is required for processing. , the processing technology is more complicated. Simultaneously, the circular cable has great limitations when it is laid indoors, especially when it is laid under the carpet. Contents of the inv...
