Description

Technical Field

[0001] This utility model relates to the field of cable equipment technology, and in particular to a twisted-pair shielded cable for network data transmission. Background Technology

[0002] Shielded cables are typically made of several or groups of conductors (at least two conductors per group) twisted together in a rope-like manner. Each group of conductors is insulated from each other and is often twisted around a central core. The entire cable is covered with a highly insulating outer layer.

[0003] In practical applications, the demands on cables in existing technologies are increasing, with higher requirements for their safety and sealing performance. At the same time, as the service life of many cables increases, their overall stability becomes unstable, which affects the service life of the equipment and its normal operation.

[0004] Therefore, this utility model provides a twisted-pair shielded cable for network data transmission. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a twisted-pair shielded cable for network data transmission.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a twisted-pair shielded cable for network data transmission, comprising a first shielding jacket,

[0007] A second shielding jacket is installed at the bottom of the first shielding jacket;

[0008] Two symmetrically distributed sealing connectors are installed at the connection between the first and second shielding jackets;

[0009] The sealing connector includes a sealing connecting plate and a limiting groove. Two sealing connecting plates are installed at the connection between the first shielding jacket and the second shielding jacket. The two sealing connecting plates are symmetrically distributed. A connecting sleeve is installed on the side of the two sealing connecting plates that are far apart. The first shielding jacket extends into the interior of one of the connecting sleeves. An elastic pressure plate is installed inside the two sealing connecting plates. An equidistant reset elastic plate is installed between the elastic pressure plate and the sealing connecting plate.

[0010] The first shielding jacket has an inner shielding layer installed inside, and cables are installed on the outer side of the inner shielding layer. The cables are arranged in a ring and are evenly distributed on one side of the inner shielding layer. A sealing strip is installed on the top of the first shielding jacket, and a sealing strip with the same structure is installed on the bottom of the second shielding jacket. The sealing strips provide an anti-slip seal for the top of the first shielding jacket and the bottom of the second shielding jacket, which facilitates vertical placement while providing a sealing and blocking effect.

[0011] In a preferred embodiment, the inner shielding layer is made of metal strip, the cable is made of carbon fiber, and both the first and second shielding jackets are made of PVC tin-plated copper. The installation of the metal strip inner shielding layer and the carbon fiber cable provides protection for the equipment during use. The PVC tin-plated copper on the outside of the first and second shielding jackets makes them particularly suitable for use in humid or corrosive environments, providing stronger corrosion resistance and extending the equipment's service life. The first shielding jacket has a first mounting cavity for use with the inner shielding layer, and the elastic pressure plate has a second mounting cavity for use with the first and second shielding jackets. The second mounting cavity allows for proper installation of the first and second shielding jackets, enabling the connection of multiple cables. The first mounting cavity inside the first shielding jacket allows for proper installation of the external limiting sleeve and the cable.

[0012] The technical effect of adopting the above-mentioned further solution is that the first shielding jacket and the second shielding jacket are installed normally through the cooperation of the second installation inner cavity, thereby enabling the connection of multiple cables. The external limiting sleeve and the cable are installed normally through the cooperation of the first installation inner cavity opened inside the first shielding jacket.

[0013] In a preferred embodiment, equidistantly distributed external limiting sleeves are installed on the outer sides of the first and second shielding jackets. Each external limiting sleeve has an equidistantly distributed counterweight plate installed on its outer side. Each counterweight plate has an installation pin installed inside. The multiple external limiting sleeves connect to the corresponding first and second shielding jackets, improving the sealing effect during actual use. By installing counterweight plates on the outer sides of the external limiting sleeves, the overall weight of the equipment is increased, improving overall stability during placement and reducing the likelihood of self-movement.

[0014] The technical effects of adopting the above-mentioned further solution are as follows: by connecting multiple external limiting sleeves with the corresponding first shielding jacket and second shielding jacket, the sealing effect during actual use is improved; by installing a counterweight plate on the outside of the external limiting sleeve, the overall weight of the equipment is increased, improving the overall stability during placement and reducing the occurrence of self-movement.

[0015] In a preferred embodiment, the reset elastic plate is made of natural rubber, the elastic pressure plate is made of synthetic rubber, and the connecting sleeve is made of polyurethane. By installing the reset elastic plate (made of natural rubber) and the elastic pressure plate (made of synthetic rubber) inside the sealing connector, the first and second shielding jackets can undergo self-deformation, allowing for better installation. The polyurethane connecting sleeve, used for sealing the first and second shielding jackets, provides high tensile strength, wear resistance, and aging resistance, and is adaptable to a wide temperature range. The second shielding jacket contains a cable and inner shielding layer of the same structure. The second shielding jacket extends into another connecting sleeve, thus facilitating a normal connection between the first and second shielding jackets.

[0016] The technical effect of adopting the above-mentioned further solution is that by installing a reset elastic plate made of natural rubber and an elastic pressure plate made of synthetic rubber, the first shielding jacket and the second shielding jacket can be self-deformed inside the sealing connector, which allows for better installation and thus ensures a normal connection between the first shielding jacket and the second shielding jacket.

[0017] In a preferred embodiment, the outer side of the first shielding jacket is provided with an installation groove for use with an external limiting sleeve. The cable is installed by using the installation groove in conjunction with the corresponding external limiting sleeve. The diameter ratio of the cable to the inner shielding layer is 1:4, which allows for better installation inside the first shielding jacket.

[0018] The technical advantage of adopting the above-mentioned further solution is that it can be installed in conjunction with the corresponding external limiting sleeve through the mounting slot, and can be better installed inside the first shielding jacket.

[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0020] By setting up a first shielding jacket, a second shielding jacket, and sealing connectors, during use, the top of the first shielding jacket and the bottom of the second shielding jacket are sealed with sealing strips to prevent slipping, facilitating vertical placement while providing a sealing and barrier effect. The installation of an inner shielding layer made of metal strip and carbon fiber cables provides protection during equipment use. The installation of PVC tin-plated copper on the outside of the first and second shielding jackets makes them particularly suitable for use in humid or corrosive environments, providing stronger corrosion resistance and extending the equipment's service life. The second mounting cavity allows for the normal installation of the first and second shielding jackets, enabling the connection of multiple cables. The first mounting cavity inside the first shielding jacket allows for the normal installation of external limiting sleeves and cables. Multiple external limiting sleeves connect with corresponding first and second shielding jackets... The shielding jacket connection improves the sealing effect during actual use. By installing a counterweight plate on the outside of the external limiting sleeve, the overall weight of the equipment is increased, improving the overall stability during placement and reducing the possibility of self-movement. The installation of a natural rubber reset elastic plate and a synthetic rubber elastic pressure plate, in conjunction with the first and second shielding jackets installed inside the sealing connector, allows for self-deformation and better installation. The use of a polyurethane connecting sleeve for sealing the first and second shielding jackets provides high tensile strength, wear resistance, and aging resistance, and adapts to a wide temperature range. The second shielding jacket extends into another connecting sleeve, thus facilitating a normal connection between the first and second shielding jackets. The entire system operates without the aid of electrical equipment, saving on overall installation and usage costs. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] like Figures 1-4 As shown, this embodiment provides a technical solution: a twisted-pair shielded cable for network data transmission, including a first shielding jacket 1, with a second shielding jacket 2 installed at the bottom of the first shielding jacket 1; two symmetrically distributed sealing connectors are installed at the connection between the first shielding jacket 1 and the second shielding jacket 2; the sealing connectors include sealing connecting discs 3 and limiting grooves 31, with two sealing connecting discs 3 installed at the connection between the first shielding jacket 1 and the second shielding jacket 2, the two sealing connecting discs 3 being symmetrically distributed, and connecting sleeves 32 installed on the side of the two sealing connecting discs 3 that are far apart from each other, the first shielding jacket 1 extending into the interior of one of the connecting sleeves 32, and both sealing connecting discs 3 having a connecting sleeve 32 installed inside. An elastic pressure plate 33 is installed between the elastic pressure plate 33 and the sealing connection plate 3, and an equidistant reset elastic plate 35 is installed between them. The inner shielding layer 14 is installed inside the first shielding jacket 1, and the cable 13 is installed on the outer side of the inner shielding layer 14. The cable 13 is in the shape of a ring and is distributed equidistantly on one side of the inner shielding layer 14. A sealing strip 11 is installed on the top of the first shielding jacket 1, and a sealing strip 11 with the same structure is installed on the bottom of the second shielding jacket 2. The sealing strip 11 provides anti-slip sealing treatment for the top of the first shielding jacket 1 and the bottom of the second shielding jacket 2, which facilitates vertical placement and provides a sealing and blocking effect. The whole process does not use electrical equipment to assist in the operation, saving the overall use and installation costs.

[0031] Going further, such as Figures 1-4As shown: the inner shielding layer 14 is made of metal strip, the cable 13 is made of carbon fiber, and the first shielding jacket 1 and the second shielding jacket 2 are both made of PVC tin-plated copper. The installation of the inner shielding layer 14 made of metal strip and the cable 13 made of carbon fiber provides protection for the equipment during use. The PVC tin-plated copper installed on the outside of the first shielding jacket 1 and the second shielding jacket 2 makes it particularly suitable for use in humid or corrosive environments, with stronger corrosion resistance and extended service life of the equipment. The first shielding jacket 1 has a first mounting cavity 12 for use with the inner shielding layer 14, and the elastic pressure plate 33 has a second mounting cavity 34 for use with the first shielding jacket 1 and the second shielding jacket 2. The first shielding jacket 1 and the second shielding jacket 2 are installed normally through the second mounting cavity 34, thereby connecting multiple cables 13. The first mounting cavity 12 inside the first shielding jacket 1 is used to install the external limiting sleeve 15 and the cable 13 normally.

[0032] Going further, such as Figure 3 As shown: In this scheme, equidistantly distributed external limiting sleeves 15 are installed on the outer sides of the first shielding jacket 1 and the second shielding jacket 2. Equally distributed counterweight plates 16 are installed on the outer sides of each external limiting sleeve 15. Each counterweight plate 16 has an installation pin 17 installed inside. The multiple external limiting sleeves 15 connect to the corresponding first shielding jacket 1 and second shielding jacket 2, improving the sealing effect during actual use. By installing counterweight plates 16 on the outer sides of the external limiting sleeves 15, the overall weight of the equipment is increased, improving the overall stability during placement and reducing the occurrence of self-movement. The reset elastic plate 3... 5 is made of natural rubber, the elastic pressure plate 33 is made of synthetic rubber, and the connecting sleeve 32 is made of polyurethane. By installing the reset elastic plate 35 made of natural rubber and the elastic pressure plate 33 made of synthetic rubber, the first shielding jacket 1 and the second shielding jacket 2 can be self-deformed inside the sealing connector for better installation. The connecting sleeve 32 made of polyurethane material is used to seal the connection between the first shielding jacket 1 and the second shielding jacket 2, which has high tensile strength, wear resistance and aging resistance, and can adapt to a wide temperature range.

[0033] Going further, such as Figures 1-4 As shown, in this scheme, the outer side of the first shielding jacket 1 is provided with an installation groove 18 for use with the external limiting sleeve 15. The installation is carried out by the installation groove 18 in conjunction with the corresponding external limiting sleeve 15. The diameter ratio of the cable 13 to the inner shielding layer 14 is 1:4, which allows for better installation inside the first shielding jacket 1. The second shielding jacket 2 is equipped with the same cable 13 and inner shielding layer 14. The second shielding jacket 2 extends into another connecting sleeve 32, thereby allowing for normal connection between the first shielding jacket 1 and the second shielding jacket 2.

[0034] Working principle:

[0035] like Figure 1-4 As shown:

[0036] When in use, the top of the first shielding jacket 1 and the bottom of the second shielding jacket 2 are sealed with sealing strips 11 to prevent slipping, which facilitates vertical placement while also providing a sealing and blocking effect.

[0037] The equipment is protected by an inner shielding layer 14 made of metal strip and a cable 13 made of carbon fiber. The PVC tin-copper plating installed on the outside of the first shielding jacket 1 and the second shielding jacket 2 makes it particularly suitable for use in humid or corrosive environments, with stronger corrosion resistance and extended service life.

[0038] The first shielding jacket 1 and the second shielding jacket 2 are installed normally through the second mounting cavity 34, thereby connecting multiple cables 13. The first mounting cavity 12 is opened inside the first shielding jacket 1 to install the external limiting sleeve 15 and the cables 13 normally. The multiple external limiting sleeves 15 are connected to the corresponding first shielding jacket 1 and second shielding jacket 2, which improves the sealing effect during actual use.

[0039] By installing a counterweight plate 16 on the outside of the external limiting sleeve 15, the overall weight of the equipment is increased, which improves the overall stability during placement and reduces the occurrence of self-movement.

[0040] By installing a reset elastic plate 35 made of natural rubber and an elastic pressure plate 33 made of synthetic rubber, the first shielding jacket 1 and the second shielding jacket 2 can be self-deformed inside the sealing connector, allowing for better installation.

[0041] By using a polyurethane connecting sleeve 32 to seal the connection between the first shielding jacket 1 and the second shielding jacket 2, it has high tensile strength, wear resistance and aging resistance, and can adapt to a wide temperature range.

[0042] The second shielding jacket 2 extends into the interior of another connecting sleeve 32, thus cooperating with the first shielding jacket 1 and the second shielding jacket 2 for normal connection. The entire operation does not require the assistance of electrical equipment, saving overall usage and installation costs.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
