Embodiment Construction

[0030] Below in conjunction with each accompanying drawing, the present invention is described in detail.

[0031] Such as figure 1 As shown, a data cable includes:

[0032] The skeleton body 1 has four fan-shaped parts 2 evenly distributed around the circumference of the skeleton body. The angle between the two side wall extension surfaces of the fan-shaped parts is A, and the range of A is 20° to 35°. An accommodating cavity 9 is formed between them; a mounting groove 5 is provided on the arc-shaped side wall of the fan-shaped part away from the skeleton body, and the side wall of the mounting groove has a channel 8 communicating with the corresponding accommodating cavity;

[0033] Four groups of twisted wire pairs 11 are respectively installed in corresponding accommodating cavities;

[0034] Solid mouse repelling block 4 is arranged in the installation groove;

[0035] Four cover plates 12 cover the corresponding accommodating chambers 9 respectively;

[0036] The wat...

Abstract

The invention discloses a data cable, which comprises a skeleton body, four groups of stranded wire pairs, solid rat expelling blocks, four covering plates, a waterproof layer and a sheath, wherein the skeleton body comprises four fan-shaped parts; an accommodating cavity is formed between two adjacent fan-shaped parts; an arc-shaped side wall of each fan-shaped part is provided with an installation groove; the four groups of stranded wire pairs are arranged in the corresponding accommodating cavities respectively; the solid rat expelling blocks are arranged in the corresponding installation grooves; the four covering plates cover the corresponding accommodating cavities respectively; the waterproof layer coats the outer sides of the skeleton body and the covering plates; and the sheath coats the outer side of the waterproof layer. The fan-shaped parts can be effectively utilized to form the installation grooves for arranging the solid rat expelling blocks, so that the space utilization rate can be effectively improved in comparison with independent arrangement of a rat expelling layer; and openings of the accommodating cavities are relatively large, and the condition that the quality of the data cable is affected because the waterproof layer is embedded in the accommodating cavities can be avoided through the arrangement of covering plates.

Description

technical field [0001] The invention relates to the field of signal transmission, in particular to data cables. Background technique [0002] With the rapid development of optical communication technology, optical cables have been widely used in the backbone network and inter-office trunk lines of wired communication networks, and it has become an inevitable trend for optical fibers to enter the access network. However, the cost of laying optical cables is too high, and the cost of joints and terminal optical-electrical conversion is expensive. Therefore, for a long time before the popularization of optical fiber, the subscriber lines of the access network will still be dominated by metal cables. As a kind of metal cable, data cable is currently an ideal transmission medium for broadband access network. It has the advantages of low manufacturing cost, simple structure, good expandability, and easy network upgrade. It is mainly used for integrated wiring of buildings, residen...
