Description

Technical Field

[0001] The utility model relates to the field of cables, in particular to an anti-interference outdoor category 7 double-shielded network cable. Background Art

[0002] The development of communication technology has driven the popularization of network applications. Nowadays, the Internet exists in every corner of people's daily life, work, social interaction and entertainment. Network cables are the most critical and basic functional units in network communications, and their performance will also have many impacts on people's use of network equipment.

[0003] Currently, the most widely used cable is Category 5e. Units with high network requirements will use Category 6 cables for wiring, but not many people may come into contact with Category 7 cables. It is mainly to adapt to the application and development of 10 Gigabit Ethernet technology. Category 7 cables are no longer unshielded twisted pair cables, but shielded twisted pair cables. They can provide a comprehensive attenuation to crosstalk ratio of at least 500MHZ and an overall bandwidth of 600MHZ. They are mainly suitable for 10 Gigabit Ethernet, which is more than twice that of Category 6 and Category 6e cables, and can reach a transmission rate of 10Gbps.

[0004] Although the existing Category 7 cables have good shielding effects, in actual applications, Category 7 cables often do not have a good outdoor working environment. When the cables are squeezed or even punctured, the internal wires may be damaged, thereby deteriorating the transmission effect of the cables. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide an anti-interference outdoor Category 7 double-shielded network cable to solve the technical problem that the internal wires of the general Category 7 cables may be damaged due to extrusion.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an anti-interference outdoor category 7 double-shielded network cable, comprising an inner skeleton, a twisted pair and a protective cover, the outer wall of the twisted pair is covered with an inner shielding layer, the inner skeleton and the outer side of the twisted pair are provided with an outer shielding layer, the outer wall of the protective cover is wrapped with an anti-puncture layer, the ends of the inner skeleton are provided with support parts, and the inner side of the support part is provided with a plurality of buffer pads.

[0007] The utility model is further configured that the inner shielding layer is an aluminum foil layer, and the outer wall of the inner frame is provided with a groove for placing the inner shielding layer.

[0008] The utility model is further configured that the outer shielding layer is an aluminum mesh braided layer.

[0009] The utility model is further configured that the stab-proof layer is a tinned copper braided metal mesh.

[0010] The utility model is further configured that the outer wall of the puncture-proof layer is provided with a waterproof layer, and the waterproof layer is made of polyethylene.

[0011] The utility model is further configured that a filling layer is arranged inside the outer shielding layer, and the filling layer is a silica gel filler.

[0012] The utility model is further configured that the twisted pair wires are formed by twisting two wires counterclockwise using a back-twisting twisting technique.

[0013] To sum up, the utility model mainly has the following beneficial effects: the utility model arranges the inner shielding layer, the outer shielding layer and the puncture-proof layer, so that the cable obtains a better shielding effect, and the metal shielding layer can also play an anti-puncture role with the puncture-proof layer. The support part can make the cable bear a certain pressure when it is squeezed, so as to prevent the pressure from directly affecting the twisted pair cable. The two effects of anti-puncture and support buffering can effectively improve the service life of the cable when working outdoors. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0019] An anti-interference outdoor Category 7 double-shielded network cable, such as Figure 1-3 As shown, it includes an inner skeleton 1, twisted pairs 2 and a protective cover 3. The inner skeleton 1 serves as an inner support for the twisted pairs 2 and separates each group of twisted pairs 2 into different areas. The twisted pairs 2 are made by twisting each other counterclockwise using the back-twisting technology.

[0020] The outer wall of the twisted pair cable 2 is covered with an inner shielding layer 4, which is an aluminum foil layer, and the outer wall of the inner skeleton 1 is provided with a groove for placing the inner shielding layer 4. The outer side of the inner skeleton 1 and the twisted pair cable 2 is provided with an outer shielding layer 5, which is an aluminum mesh braided layer. The inner shielding layer 4 and the outer shielding layer 5 can effectively improve the shielding effect of the twisted pair cable 2, and the outer wall of the protective sleeve 3 is wrapped with an anti-puncture layer 6, and the protective sleeve 3 is located between the outer shielding layer 5 and the anti-puncture layer 6. The anti-puncture layer 6 made of tinned copper braided metal mesh can have a good anti-puncture effect, and can achieve the dual effects of shielding and anti-puncture of the twisted pair cable 2 in combination with the inner shielding layer 4 and the outer shielding layer 5.

[0021] A support portion 8 is provided at each end of the inner skeleton 1, and a plurality of buffer pads 9 are provided on the inner side of the support portion 8. The outer side of the support portion 8 is arc-shaped, which can adapt to the shape of the outer protective cover 3 to protect the internal twisted pair 2 as much as possible. When the cable is squeezed, the pressure is first buffered by the metal shielding layer and the anti-puncture layer 6, and the remaining pressure acts directly on the support portion 8, which effectively buffers the pressure and prevents the twisted pair 2 from being directly squeezed.

[0022] Furthermore, the buffer pad 9 can reduce the damage of the twisted pair 2 caused by pressure when the support portion 8 is deformed and contacts the twisted pair 2 .

[0023] A filling layer 10 is disposed inside the outer shielding layer 5 . The filling layer 10 is a silica gel filler, which can further improve the insulation effect of the twisted pair cable 2 .

[0024] The outer wall of the puncture-proof layer 6 is provided with a waterproof layer 7, which is made of polyethylene. The polyethylene waterproof layer 7 can increase the service life of the cable when working outdoors.

[0025] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model.
