Description

Technical Field

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

[0002] Data cable is a cable specially used for transmitting data signals. It is also called twisted pair or star-twisted multi-core symmetrical cable for digital communication. The structure of data cable mainly includes central conductor, insulation layer, shielding layer and outer sheath.

[0003] Generally, common data cables are equipped with a cross skeleton, which is mainly used to support and protect the internal structure of the cable. During data transmission, the cable needs to withstand various external and internal pressures and tensions. The existence of the cross skeleton increases the strength and stability of the cable, prevents the cable from being damaged or broken, and ensures the stability and security of data transmission. However, the cross skeleton used in the existing data cable has extended ends in four directions. Therefore, when the data cable is bent, the extended ends of the cross skeleton are evenly distributed in four directions, and the gaps between them are relatively large, which makes the area between the two extended ends a weak link in the cable structure. When bending force is applied, this weak link is more likely to deform, resulting in an increase in the curvature of the cable in this direction, which will cause the core to bend and squeeze due to the larger bending degree, affecting data transmission. In addition, when the existing data cable is in use, the entire core is protected by an external outer sheath, and the core cannot be provided with a good anti-cutting ability. Utility Model Content

[0004] The purpose of the utility model is to provide a data cable with anti-cutting and anti-bending functions, 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:

[0006] A data cable with anti-cutting and anti-bending functions comprises an outer sheath, a flame-retardant filling layer is fixedly installed in the outer sheath, a plurality of first reinforcing ribs are fixedly installed in the flame-retardant filling layer, an inner sheath is fixedly installed in the flame-retardant filling layer, a shielding layer is laid between the flame-retardant filling layer and the inner sheath, a plurality of tear ropes are fixedly installed in the inner sheath, a plurality of twisted pair wires are movably installed in the inner sheath, and a cross partition frame is movably installed between the plurality of twisted pair wires.

[0007] As a further optimization solution of the present utility model, the outer sheath and the inner sheath are both made of polyethylene.

[0008] As a further optimization solution of the present invention, the flame retardant filling layer is a polyester tape. By setting the polyester tape, mutual interference between twisted pair cables can be prevented, thereby ensuring data transmission quality.

[0009] As a further optimization solution of the present invention, the first reinforcing rib is made of polycarbonate. By arranging a plurality of first reinforcing ribs at equal intervals in the flame-retardant filling layer, the bending resistance of the entire data cable can be improved.

[0010] As a further optimization solution of the present invention, a metal mesh is laid between the outer sheath and the flame-retardant filling layer. Through the arrangement of the metal mesh, the anti-cutting ability of the data volume can be improved in cooperation with a plurality of first reinforcing ribs.

[0011] As a further optimization scheme of the present invention, a weight-reducing cavity is opened at the center position of the cross partition frame, and a plurality of second reinforcing ribs are fixedly installed on the inside of the weight-reducing cavity, and the second reinforcing ribs are placed between the two extending ends of the cross partition frame. By opening the weight-reducing cavity, on the one hand, the overall weight of the cross partition frame can be reduced, and on the other hand, a plurality of second reinforcing ribs are installed in the weight-reducing cavity, which can cooperate with the cross partition frame to further enhance the bending resistance of the data cable.

[0013] The utility model discloses a data cable with anti-cutting and anti-bending functions, wherein a flame retardant filling layer is arranged in the outer sheath, and a first reinforcing rib is arranged in the flame retardant filling layer. Meanwhile, a metal mesh is laid between the flame retardant filling layer and the outer sheath, so as to improve the overall anti-cutting ability of the data cable.

[0018] 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.

[0019] like Figure 1-Figure 2 As shown, the utility model provides a data cable with anti-cutting and anti-bending functions, including an outer sheath 1, a flame retardant filling layer 2 is fixedly installed in the outer sheath 1, a plurality of first reinforcing ribs 3 are fixedly installed in the flame retardant filling layer 2, an inner sheath 5 is fixedly installed in the flame retardant filling layer 2, a shielding layer 4 is laid between the shielding layer 4 and the inner sheath 5, a plurality of tear ropes 6 are fixedly installed in the inner sheath 5, a plurality of groups of twisted pair wires 7 are movably installed in the inner sheath 5, and a cross partition frame 8 is movably installed between the plurality of groups of twisted pair wires 7.

[0020] like Figure 1-Figure 2 As shown, the outer sheath 1 and the inner sheath 5 are both made of polyethylene, and the flame retardant filling layer 2 is a polyester belt. The setting of the polyester belt can prevent mutual interference between the twisted pair cables 7 and ensure the quality of data transmission. The first reinforcing rib 3 is made of polycarbonate. By equidistantly arranging multiple first reinforcing ribs 3 in the flame retardant filling layer 2, the bending resistance of the entire data cable can be improved. A metal mesh 11 is laid between the outer sheath 1 and the flame retardant filling layer 2. Through the setting of the metal mesh 11, the anti-cutting ability of the data volume can be improved in conjunction with multiple first reinforcing ribs 3. A weight-reducing cavity 9 is opened at the center position of the cross partition frame 8, and multiple second reinforcing ribs 10 are fixedly installed on the inside of the weight-reducing cavity 9, and the second reinforcing ribs 10 are placed in the weight-reducing cavity 9 between the two extending ends of the cross partition frame 8. By opening the weight-reducing cavity 9, on the one hand, the overall weight of the cross partition frame 8 can be reduced, and on the other hand, multiple second reinforcing ribs 10 are installed in the weight-reducing cavity 9, which can cooperate with the cross partition frame 8 to further improve the bending resistance of the data cable.

[0021] It should be noted that the utility model is a data cable with anti-cutting and anti-bending functions. When the outer side of the outer sheath 1 is cut by an external object, the metal mesh 11 between the outer sheath 1 and the flame-retardant filling layer 2 can play a first-level anti-cutting role. At the same time, with the help of a plurality of first reinforcing ribs 3 arranged in the flame-retardant filling layer 2, the outer sheath 1 can be supported and anti-bending, and its hard material can play a second-level anti-cutting role for the entire data cable.

[0022] When the entire data cable is bent due to laying, the first reinforcing rib 3, the cross partition frame 8 and the weight-reducing cavity 9 can ensure that the entire data cable has a normal bending curvature, prevent the twisted pair cable 7 from exceeding the specified bending curvature due to excessive bending of the data cable, and prevent the twisted pair cable 7 from being deformed at the bend, thereby causing attenuation or distortion of signal transmission.

[0023] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
