Problems solved by technology

[0006] The above-mentioned patents have the following shortcomings: first, since all wire pairs are shielded together by the same shielding layer, it is difficult to avoid interference and attenuation during signal transmission, which affects communication effect; secondly, when trying to use the cable of this patented structure to make a spring form, the bendability and rebound performance are poor, which affects the service life, so it is critical to the use environment or occasion; thirdly, due to the sheath (patent The outer sheath) is made of low-smoke flame-retardant polyvinyl chloride, so the low-temperature resistance is lacking, and it can only withstand low temperatures of about -40°C

Embodiment 1

[0022] See figure 1 , the cross-sectional shape of the cable for 3G data communication is given. The cable is composed of a cable core 1 and a sheath layer 2 outside the cable core 1. The cable core 1 includes two first wire pairs 11 and two second wire pairs. 12. The isolation layer 13, the ground wire 14 and a set of filling ropes 15 are called wire pairs because they can be understood as a pair of wires based on common knowledge. Two first wire pairs 11 and two second wire pairs 12 mean There are eight wires in total. In this embodiment, the two first wire pairs 11 each include a pair of first conductors 111, first and second wrapping layers 112, 113 and a first shielding layer 114, each of which is coated outside the pair of first conductors 111. There is a first insulating layer 1111, the first insulating layer 1111 is a PE insulating layer, that is, a foamed PE insulating material, and the conductor 111 is composed of a copper foil wire with a diameter of 0.25 mm and...

Embodiment 2

[0029] The diagram is omitted, only the first conductor 111 is changed to be composed of a copper foil wire with a diameter of 0.27mm and an annealed copper wire with a diameter of 0.077mm as required; the first and second wrapping tapes 112, 113 Change the width of the first and second shielding layers 114 and 122 to 18mm and the thickness to 0.05mm; change the width of the release paper of the isolation layer 13 to 15㎜, change the thickness to 0.05㎜, change the diameter of forty tinned copper wires or annealed copper wires of the ground wire 14 to 0.083㎜, change the diameter of a bare copper foil wire to 0.27㎜, and change the width of the release paper to It is 25mm and the thickness is changed to 0.05mm, and the rest are the same as the description of embodiment 1.

Embodiment 3

[0031] The figure is omitted, only the first conductor 111 is changed to be composed of a copper foil wire with a diameter of 0.23 mm and the required number of tinned copper wires with a diameter of 0.083 mm twisted; the first and second wrapping tapes 112, 113 Change the width of the first and second shielding layers 114 and 122 to 10 mm and the thickness to 0.03 mm; change the width of the release paper of the isolation layer 13 to 0.15 mm; 25㎜, the thickness is changed to 0.03㎜, and the structure of the ground wire 14 is changed to: the diameter of forty tinned copper wires or annealed copper wires is changed to 0.077㎜, and the diameter of one bare copper foil wire is changed to 0.23㎜. The width of the release paper was changed to 15mm and the thickness was changed to 0.03mm, and the rest were the same as those described in Example 1.

Abstract

The invention provides a cable for 3G data communication, belonging to the field of wire cable technology. The cable comprises a cable core and a sheath layer. The cable core comprises at least two first line pairs, at least two second line pairs and a separating layer. The cable is characterized in that: each first line pair is composed of a pair of first conductors which are coated with a firstinsulating layer respectively, first and second winding cladding layers and a first shielding layer; each second line pair is composed of a pair of second conductors which are coated with a second insulating layer respectively and a second shielding layer, an intertwist pitch of a pair of the second conductors is different from an intertwist pitch of a pair of the first conductors, the second line pairs are positioned between two adjacent first line pairs, the second shielding layer is positioned outside of the second conductors, the separating layer is positioned outside of the first line pairs and the second line pairs, and each first conductor and each second conductor are formed by intertwining of a copper foil wire and a plurality of tinned copper wires or a plurality of soft brass wires respectively. The cable has the following advantages: a communication effect is ensured; a service life of the cable is prolonged, and adaptability of a cable use occasion is improved; and the cable has a low temperature resistant effect.

Description

technical field [0001] The invention belongs to the technical field of electric wires and cables, and in particular relates to a cable for 3G data communication. Background technique [0002] The 3G mentioned above is well known in the industry and is an abbreviation of 3rd Generation in English, referring to the third generation of mobile communication technology. Compared with the first generation of analog mobile phones (1G) and the second generation of digital mobile phones (2G) such as GSM and TDMA, it refers to a new generation of communication system that combines wireless communication with multimedia communication such as the Internet. It can handle various media forms such as images, music, and video streams, and provide various information services including web browsing, teleconferencing, and e-commerce. [0003] Of course, 3G data communication cables can also be applied to industrial numerical control equipment such as CNC lathes, robots, security systems, tel...
