A Category 5e shielded network cable

Abstract

This utility model discloses a Category 5e shielded network cable, relating to the field of network cables. The utility model includes a protective sleeve with multiple mounting strips on its outer wall. Each mounting strip has a slot, and insert strips are inserted into the slots. Buffer strips are mounted on the insert strips, and protective rings connect the multiple buffer strips. The protective sleeve has a braided shielding layer inside. By incorporating buffer strips and protective rings, this utility model ensures that when the cable is subjected to tensile force, both the buffer strips and protective rings deform. Since the deformation of the buffer strips and protective rings is limited, they provide tensile resistance and improve the tensile strength of the network cable, preventing breakage when stretched. Simultaneously, the buffer strips and protective rings deform upon impact, further buffering the impact force and protecting the cable from damage caused by significant impacts, thus improving the overall protection of the cable.

Description

Technical Field

[0001] This utility model relates to the field of network cables, specifically a Category 5e shielded network cable. Background Technology

[0002] Category 5e cable refers to Category 5e unshielded twisted pair and shielded twisted pair cable. It is an upgraded version of Category 5 cable. It is a cable that has improved some of the performance of existing Category 5 shielded twisted pair cable. Many performance parameters, such as near-end crosstalk, attenuation crosstalk ratio, and return loss, have been improved, making it the mainstream cable used today.

[0003] According to Chinese Patent No. CN211669992U, a shielded Category 5e data cable for wind power generation is disclosed. This utility model cable has a strong flame retardant effect. The cable cores A, B, and C are filled with a glass fiber flame retardant filling layer between them and the aluminum foil wrapping shielding layer. Glass fiber has good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, which can play an insulating and flame retardant role and prevent leakage.

[0004] Regarding the aforementioned patent content, the network cable is designed with anti-tension ropes to provide tensile resistance. However, the anti-tension ropes located close to the innermost part of the cable are insufficient to improve the overall tensile strength of the network cable. This means that the network cable may be damaged when subjected to large external tensile forces, thereby reducing the protective effect on the network cable. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a Category 5e shielded network cable to solve the technical problem of poor tensile strength of network cables.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a Category 5e shielded network cable, including a protective sleeve, the outer wall of which is provided with multiple mounting strips, each mounting strip having a slot, and inserts being inserted into the slots, each insert having a buffer strip, and multiple buffer strips being connected by protective rings, the protective sleeve having a braided shielding layer inside, and the braided shielding layer having an aluminum foil wrapped shielding layer inside.

[0007] By adopting the above technical solution, when the cable is subjected to external impact, the buffer strip will deform upon impact, thereby buffering the impact force and protecting the cable.

[0008] Furthermore, the aluminum foil wrapping shielding layer has a first cable core, a second cable core, and a third cable core inside, which are wound together to form a three-strand braid.

[0009] By adopting the above technical solution, when the network cable is subjected to tension, the twisted and bent cable cores are subjected to different directions of force at each point, thus dispersing the tension and resulting in strong tensile strength.

[0010] Furthermore, a flame-retardant filler layer is filled between the first cable core, the second cable core, and the third cable core and the inner wall of the aluminum foil wrapping shielding layer.

[0011] By adopting the above technical solution, the flame-retardant filler layer can be easily used to improve the flame-retardant effect of network cables.

[0012] Furthermore, the insert is adapted to the slot, and the buffer strip is slidably connected to the slot via the insert.

[0013] By adopting the above technical solution, when it is necessary to install a buffer strip, the insert on the buffer strip can be inserted into the slot, thereby facilitating the positioning of the buffer strip.

[0014] Furthermore, the protective ring is made of rubber material.

[0015] By adopting the above technical solutions, it is convenient to protect network cables and improve the protection effect of network cables.

[0016] Furthermore, the flame-retardant filler layer is made of glass fiber.

[0017] By adopting the above technical solutions, glass fiber has good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, which can play an insulating and flame-retardant role and prevent leakage.

[0018] Furthermore, the thickness of the fabricated shielding layer is greater than the thickness of the aluminum foil wrapping shielding layer.

[0019] By adopting the above technical solutions, the shielding effect of network cables can be improved, thereby enhancing the performance of network cables.

[0020] Furthermore, multiple mounting strips are arranged in a circular array on the outer wall of the protective sleeve, and the mounting strips are made of rubber material.

[0021] By adopting the above technical solution, the installation strip is made of rubber material, which makes it easy to bend and also facilitates the insertion of buffer strips.

[0022] Furthermore, the buffer strip is made of rubber material and is cylindrical.

[0023] By adopting the above technical solutions, the installation of buffer strips can improve the protection effect on cables.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, by setting up a buffer strip and a protective ring, will deform when the cable is subjected to tensile force. Since the deformation degree of the buffer strip and the protective ring is limited, it can play a role in resisting tension and improve the tensile resistance of the network cable, preventing the network cable from breaking when pulled. At the same time, the buffer strip and the protective ring will deform when impacted, thereby buffering the impact force to protect the cable, avoid damage to the network cable from large impacts, and improve the protection effect of the cable.

[0026] 2. This utility model is equipped with a strip and a slot. When the buffer strip and protective ring need to be replaced, the buffer strip can be pulled to move the strip out of the slot, so that the buffer strip can be removed for replacement of the buffer strip and protective ring.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] The embodiments of this utility model will be described below based on its overall structure.

[0035] Example 1:

[0036] A Category 5e shielded network cable, such as Figures 1-5As shown, the device includes a protective sleeve 1. The outer wall of the protective sleeve 1 is provided with multiple mounting strips 11. The mounting strips 11 are provided with slots 13, and inserts 12 are inserted into the slots 13. Buffer strips 9 are installed on the inserts 12, and protective rings 10 are connected between the multiple buffer strips 9. When the cable is subjected to external impact, the buffer strips 9 will deform upon impact, thereby buffering the impact force to protect the cable. The protective sleeve 1 is provided with a braided shielding layer 2 inside, and an aluminum foil wrapped shielding layer 3 is provided inside the braided shielding layer 2.

[0037] See Figures 1-3 The aluminum foil-wrapped shielding layer 3 has a first cable core 5, a second cable core 7, and a third cable core 8 inside. The first cable core 5, the second cable core 7, and the third cable core 8 are twisted together into a three-strand braid so that when the network cable is subjected to tension, the twisted and bent cable cores are subjected to different directions of force at each point, thus dispersing the tension and providing strong tensile strength. The thickness of the braided shielding layer 2 is greater than the thickness of the aluminum foil-wrapped shielding layer 3, which improves the shielding effect of the network cable and thus improves the performance of the network cable.

[0038] See Figures 1-5 The insert 12 is adapted to the slot 13. The buffer strip 9 is slidably connected to the slot 13 through the insert 12. When the buffer strip 9 needs to be installed, the insert 12 on the buffer strip 9 can be inserted into the slot 13 to facilitate the positioning of the buffer strip 9. The protective ring 10 is made of rubber material, which facilitates the protection of network cables and improves the protection effect of network cables. Multiple mounting strips 11 are distributed in a ring array on the outer wall of the protective sleeve 1. The mounting strips 11 are made of rubber material, which makes them easy to bend and easy to insert the buffer strip 9. The buffer strip 9 is made of rubber material and is cylindrical. The setting of the buffer strip 9 can improve the protection effect of the cable.

[0039] Example 2:

[0040] Based on the above embodiment one, the following structure will be set to improve the flame retardant effect of the cable.

[0041] Specifically, a flame-retardant filler layer 4 is filled between the first cable core 5, the second cable core 7, and the third cable core 8 and the inner wall of the aluminum foil wrapping shielding layer 3. The flame-retardant filler layer 4 is made of glass fiber, which has good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, and can play the role of insulation and flame retardancy to prevent leakage.

[0042] The working principle of this utility model is as follows: First, the aluminum foil wrapping shielding layer 3 can play a shielding role. The flame-retardant filling layer 4 is made of glass fiber. Glass fiber has good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, which can play an insulating and flame-retardant role and prevent leakage. When the cable is subjected to external tensile force, the buffer strip 9 and the protective ring 10 will deform. Since the deformation of the buffer strip 9 and the protective ring 10 is limited, they can play a tensile resistance role. If the cable is subjected to external impact, the buffer strip 9 and the protective ring 10 will deform upon impact, thereby buffering the impact force to protect the cable and prevent the network cable from being damaged by a large impact.

[0043] The first cable core 5, the second cable core 7, and the third cable core 8 are twisted together into a three-strand braid, which can improve the tensile strength. When it is necessary to replace the buffer strip 9 and the protective ring 10, the buffer strip 9 can be pulled to remove the insert 12 from the slot 13, so that the buffer strip 9 can be removed for replacement of the buffer strip 9 and the protective ring 10.
