The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1, a preferred embodiment of the present invention provides a novel cable framework, which includes a plurality of framework pieces sharing a head end, wherein widths of the plurality of framework pieces are gradually increased from the head end to a tail end; the framework piece is provided with a hanging rack device, and the hanging rack device comprises a hanging rack, a clamping groove and a hook; the hanging rack is embedded on the framework piece, the clamping groove is formed in the hanging rack, and the hook is inserted into the clamping groove; the hook is of an open ring structure, and the opening of the open ring faces upwards or to the side face.

The utility model discloses a cable skeleton is used for holding the twisted-pair line including a plurality of skeleton pieces of head end altogether, the space that forms between the adjacent skeleton piece. The round twisted pairs are respectively in contact with and supported by adjacent skeleton pieces. Because circular twisted-pair line generally can not contact with the skeleton piece head end, therefore the width of skeleton piece head end need not to be the same with terminal width, the utility model discloses in, the width of a plurality of skeleton pieces increases gradually to the end by the head end. The longitudinal length of the cable carcass generally corresponds to the length of the cable, i.e. the longitudinal length of the cable carcass is generally much larger than its cross-sectional width. After the cross-sectional width of the cable framework is reduced by a part, the reduced material is enlarged by the longitudinal length of the cable framework, and finally, the overall material of the cable framework is sharply reduced. The number of the framework pieces of the cable framework of the utility model can be any number, for example, three framework pieces, four framework pieces or five framework pieces at the head end can be provided.

In the process of engineering operation such as cable laying, the utility model is placed at a proper position, a plurality of twisted pairs are separated from each other to prevent crosstalk and simultaneously support the twisted pairs, cables can be wound in different framework pieces in a classified manner according to different types, and redundant cables at the tail end of the cables are wound on the hook, so that a worker can stretch the cables wound on the framework pieces by directly dragging the cables on the hook, and the problem of irregular hanging and placing caused by random placing of the cables is avoided while the cables are conveniently extracted; the technical problem that the existing temporary cable support is inapplicable to cable hanging operation is solved, and therefore the tail end redundant cables are bundled on the hook, so that the cables can be conveniently taken and placed by workers, and the cable laying work efficiency of the constructors is improved.

In another embodiment, the plurality of skeleton sheets have the same structure or at least one of the plurality of skeleton sheets has a terminal width different from the terminal widths of the other skeleton sheets. The utility model discloses a plurality of skeleton pieces can adopt the same structure also can adopt different structures, as long as the width of these skeleton pieces is increased gradually to the end by the head end can. In an embodiment, at least one of the plurality of matrix tablets has a terminal end width different from the terminal end widths of the other matrix tablets. The distance between the twisted pair supported on the matrix sheet and the adjacent twisted pair varies due to the different width of the end of a certain matrix sheet. On one hand, the change of the distance between the adjacent twisted pairs can improve the function of near-end crosstalk attenuation inside the cable; on the other hand, when a plurality of cables are wound together, the relative positions of twisted pairs in the plurality of cables are changed, so that the external crosstalk defense degree can be obviously improved.

In another embodiment, the ends of the skeleton sheet with the larger end width are formed with slots. When the skeleton sheet with a larger end width exists in the skeleton sheet, although the internal near-end crosstalk attenuation and the external crosstalk defense degree of the cable can be improved, the material of the skeleton sheet is increased. In order to further reduce the number of the frame plate materials, on the premise that the frame plate with the larger end width supports the twisted pair, a groove can be formed at the end of the frame plate to reduce the number of the end materials.

In another embodiment, the slots enable the tail end of the framework piece to form two wing parts, and the tail end width of the wing parts is the same as the width of the head end of the framework piece. Since the width of the tail end of the wing part is approximately the same as that of the head end of the framework piece, the wing part is enough to support the twisted pair placed on the wing part.

In another embodiment, the cable carcass comprises a first carcass ply, a second carcass ply, a third carcass ply and a fourth carcass ply sharing a head end; the central axes of the first framework tablet and the second framework tablet are superposed, and the central axes of the third framework tablet and the fourth framework tablet are superposed; the central axes of the first framework tablet and the second framework tablet are vertical to the central axes of the third framework tablet and the fourth framework tablet. In this embodiment, the end width of the third matrix sheet is greater than the end widths of the other matrix sheets. In this embodiment, the end of the third frame piece is formed with a V-shaped slot. In this embodiment, the widths of the head ends of the first skeleton tablet, the second skeleton tablet, the third skeleton tablet and the fourth skeleton tablet are all 0.3-0.5 mm; the widths of the tail ends of the first framework tablet, the second framework tablet and the fourth framework tablet are all 0.8-1.2 mm; the width of the tail end of the third framework tablet is 1.8-2.5 mm. In this embodiment, the distance from the bottom end of the V-shaped open groove to the head end of the third frame piece is the same as the width of the tail end of the third frame piece.

The cable framework manufactured by adopting the size can better form on one hand, and can better support the twisted pair on the other hand. Compare the cable skeleton of this embodiment with traditional cross skeleton, its materials can be saved more than 50%, and electrical properties more can show the improvement.

In another embodiment, the card slot is a T-shaped card slot; the split ring is a plane ring or a three-dimensional structure, and the starting point and the terminal point of the three-dimensional split ring are not in the same plane. The T-shaped clamping groove can enable the hook to be more stably inserted.
