Description

Technical Field

[0001] The utility model relates to the technical field of data cables, in particular to a bending-resistant data cable. Background Art

[0002] Data cable is a cable specially used for transmitting data signals. It is an indispensable part of modern communication networks. It is mainly composed of conductors, insulation layers, shielding layers and protective layers. These components work together to ensure the stability and reliability of data during transmission. Data cables are widely used in computer networks, communication systems, security monitoring, audio and video transmission and other fields.

[0003] In order to make the data cable more stable during use, multiple groups of twisted pair cables are separated by a cross separator, which can effectively reduce the crosstalk coupling between the wire pairs and improve the balance characteristics of the cable by separating and fixing the wire cores inside the cable. For example, the Chinese utility model patent disclosed by publication number CN218886886U: a high-frequency data cable, which uses a cross separator, a braided shielding layer, a cable core and a conductive fiber layer to separate the cable cores by a cross separator to avoid mutual interference, and uses a braided shielding layer and a conductive fiber layer for double-layer protection, which has better It has a strong anti-electromagnetic interference effect to avoid signal data interference, thereby improving the stability of the cable when in use. However, due to the structure of the cross divider, when the data cable is bent, the bending resistance between the two extended ends of the cross divider is not high, so when the data cable is bent, the supporting effect of the cross divider will be limited, resulting in an increase in the bending degree of the cable, that is, the four extended ends of the cross divider are separated from the inner side of the protective layer of the cable. At the same time, the two extended ends of the cross divider will be squeezed and move relative to each other, making the data cable's anti-bending ability weaker. Utility Model Content

[0004] The purpose of the utility model is to provide a data cable that is resistant to bending, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] As a further optimization solution of the utility model, a shielding layer is fixedly installed between the aluminum foil and the insulating layer, and the shielding layer is a metal woven mesh. Through the cooperation of the shielding layer and the aluminum foil, the anti-interference ability of the data cable can be improved.

[0009] As a further optimization scheme of the utility model, the four extended ends of the dividing cross are respectively provided with support plates, the dividing cross and the support plate are integrally formed, and the extension lines of the four support plates are ring-shaped, and a support plate is respectively provided at the four ends of the dividing cross, so that the dividing cross can be better supported and installed in the outer sheath, aluminum foil and insulating layer, providing good bending resistance for the entire data cable.

[0010] As a further optimization scheme of the utility model, flexible sheets are provided on both sides of the four support plates. The flexible sheets are made of TPE soft rubber material. Deformable flexible sheets are respectively provided on both sides of the four support plates, which can play a good limiting role on the wire core and improve the stability of the wire core when it is covered with the insulating layer, aluminum foil and outer sheath, so that the wire core can be stably placed in the corresponding position on the outside of the dividing cross.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The anti-bending data cable of the utility model has a support plate fixedly installed at each of the four ends of the separation cross, so that the outer side of the support plate can be closely fitted with the inner side of the insulation layer, so that when the data cable is bent, the two adjacent extension ends of the two separation crosses will not be forced to fit together, thereby ensuring the anti-bending ability of the data cable;

[0017] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0018] like Figure 1-Figure 2 As shown, the utility model provides a bending-resistant data cable, comprising an outer sheath 1, an aluminum foil 2 is fixedly installed on the inner side of the outer sheath 1, a plurality of tear ropes 3 are fixedly installed between the outer sheath 1 and the aluminum foil 2, an insulating layer 4 is fixedly installed on the inner side of the aluminum foil 2, a plurality of wire cores 5 are arranged in the insulating layer 4, two wire cores 5 form a group, and four groups of wire cores 5 are arranged in the insulating layer 4, and a partition cross 6 is also movably installed in the insulating layer 4 between the four groups of wire cores 5.

[0019] A shielding layer 9 is fixedly installed between the aluminum foil 2 and the insulating layer 4, and the shielding layer 9 is a metal braided mesh. Through the cooperation of the shielding layer 9 and the aluminum foil 2, the anti-interference ability of the data cable can be improved. The insulating layer 4 is made of polyester tape, and is double-coated between the shielding layer 9 and multiple support plates 7. The four extended ends of the partition cross 6 are respectively provided with support plates 7. The partition cross 6 and the support plate 7 are integrally formed, and the extension lines of the four support plates 7 are ring-shaped. A support plate 7 is respectively provided at the four ends of the partition cross 6, which can enable the partition cross 6 to be better supported and installed in the outer sheath 1, the aluminum foil 2, and the insulating layer 4, providing good bending resistance for the entire data cable. Flexible sheets 8 are provided on both sides of the four support plates 7. The flexible sheets 8 are made of TPE soft rubber. Deformable flexible sheets 8 are respectively provided on both sides of the four support plates 7, which can play a good limiting role on the core 5, improve the stability of the core 5 when coated with the insulating layer 4, the aluminum foil 2, and the outer sheath 1, so that the core 5 can be stably placed at the corresponding position outside the partition cross 6.

[0020] It should be noted that the utility model is a bending-resistant data cable. When the data cable is bent, the support plates 7 arranged at the four ends of the dividing cross 6 can disperse the stress generated when the data cable is bent. That is, when the data cable is bent by external force, the outer surfaces of the four support plates 7 have an arc in the shape of an extended line ring and are fitted to the inner side of the insulating layer 4, which can prevent the extended end of the dividing cross 6 from being torqued or pressurized, thereby better dispersing the bending stress and preventing the core 5 from being misaligned, effectively improving the bending resistance of the data cable and preventing the data cable from being excessively bent and causing damage to the core 5.
