Description

Technical Field

[0001] This utility model relates to the field of local area network cable technology, and in particular to a highly flame-retardant and fire-resistant symmetrical cable for broadband local area networks. Background Technology

[0002] Broadband LAN symmetrical cables are cables used to achieve high-speed data transmission in LANs. Current communication cables consist of high-speed insulated polyethylene uniformly wrapped around a single-core copper conductor, twisted together using a twisting device, then covered with insulating PE polyester tape, and finally extruded with polyvinyl chloride (PVC) for sheathing. This structure results in a very narrow transmission bandwidth and poor signal transmission.

[0003] The prior art patent application CN202855427U discloses a symmetrical cable for local area networks. This utility model describes a symmetrical cable for local area networks where the four twisted pairs in the twisted wire unit employ a specific twisted pair pitch combination. This rationally designed cable pitch helps reduce near-end crosstalk interference and improves far-end crosstalk defense, thereby improving the quality of the transmitted signal and meeting the broadband, digital transmission needs of program-controlled switching communication systems. Secondly, it improves signal transmission quality, maximizes the cable's flame retardancy and fire resistance, and enhances its unidirectional properties, reducing external electromagnetic interference and digital transmission. The effective transmission distance is also extended to some extent. Thirdly, the tin-plated conductor braided layer further helps reduce near-end crosstalk interference and improve far-end crosstalk defense, thus improving the quality of the transmitted signal.

[0004] However, the existing cables are connected by piercing clamps. If the connected cables are subjected to a certain external force during use, the cable connection is prone to breakage, resulting in low stability. Utility Model Content

[0005] The purpose of this utility model is to provide a highly flame-retardant and fire-resistant symmetrical cable for broadband local area networks, which aims to solve the problem that existing cables are connected by piercing clamps, and the connected cables are prone to breakage at the connection point if subjected to certain external forces during use, resulting in low stability.

[0006] To achieve the above objectives, this utility model provides a highly flame-retardant and fire-resistant symmetrical cable for broadband local area networks, comprising a symmetrical cable body and a protection mechanism. The protection mechanism includes an installation cylinder, a sliding ring, a retaining ring, a fixing ring, a retaining seat, and two fixing components. The installation cylinder is fixedly connected to one end of the symmetrical cable body and is located on the outer side wall of the symmetrical cable body. The sliding ring is slidably connected to the installation cylinder and is located on the outer side wall of the installation cylinder. The retaining ring is fixedly connected to one end of the sliding ring. The fixing ring is fixedly connected to the outer side wall of the symmetrical cable body and is located at the end of the symmetrical cable body away from the installation cylinder. The retaining seat is fixedly connected to one end of the fixing ring. The two fixing components are respectively disposed at both ends of the retaining ring and the fixing ring.

[0007] The fixing component includes a fixing clamp, a fixing block, a limiting rod, and a telescopic kit. The fixing block has a limiting hole. The fixing clamp is fixedly connected to one end of the fixing ring. The fixing block is fixedly connected to the retaining ring. The limiting rod is slidably connected to the fixing clamp and passes through the fixing clamp. The telescopic kit is disposed on the fixing clamp and the limiting rod.

[0008] The telescopic kit includes a telescopic spring and a movable block. The movable block is fixedly connected to one end of the limiting rod. The two ends of the telescopic spring are fixedly connected to the movable block and the fixed clamping block, respectively, and the limiting rod is located inside the telescopic spring.

[0009] The protection mechanism further includes two limiting components, each including a slider and a groove. The slider is fixedly connected to the sliding ring, and the groove is located at one end of the mounting cylinder. The slider is slidably connected to the mounting cylinder and is located within the groove.

[0010] The high flame-retardant and fire-resistant broadband local area network symmetrical cable further includes a flame-retardant layer, which is fixedly connected to the symmetrical cable body and located on the outer side wall of the symmetrical cable body.

[0011] This utility model discloses a highly flame-retardant and fire-resistant symmetrical cable for broadband local area networks. When two symmetrical cable bodies are connected, the sliding ring and the retaining ring move towards one end of the retaining seat, allowing the retaining ring to insert into the retaining seat. One end of the retaining ring is then in contact with the fixing ring. At this point, the retaining ring and the retaining seat are connected and fixed by two fixing components. The retaining ring and the retaining seat seal and protect the connection point of the two symmetrical cable bodies, ensuring that the two symmetrical cable bodies will not break under external force, thereby improving the stability of the cable connection.

[0019] This utility model provides a highly flame-retardant and fire-resistant symmetrical cable for broadband local area networks, comprising a symmetrical cable body 113, a flame-retardant layer 114, and a protective mechanism. The protective mechanism includes an mounting cylinder 103, a sliding ring 104, a retaining ring 102, a fixing ring 101, a retaining seat 105, two limiting components, and two fixing components. The fixing components include a fixing clamp 110, a fixing block 108, a limiting rod 115, and a telescopic assembly. The fixing block 108 has a limiting hole 109. The telescopic assembly includes a telescopic spring 112 and a moving block 111. The limiting components include a slider 107 and a sliding groove 106. This solution solves the problem that existing cable connections using piercing clamps are prone to breakage at the connection point when subjected to external force, resulting in low stability. It is understood that the flame-retardant layer 114 reduces the risk of combustion of the symmetrical cable body 113, thereby improving the safety of the symmetrical cable body 113.

[0020] In this embodiment, the mounting cylinder 103 is fixedly connected to one end of the symmetrical cable body 113 and is located on the outer side wall of the symmetrical cable body 113. The sliding ring 104 is slidably connected to the mounting cylinder 103 and is located on the outer side wall of the mounting cylinder 103. The retaining ring 102 is fixedly connected to one end of the sliding ring 104. The fixing ring 101 is fixedly connected to the outer side wall of the symmetrical cable body 113 and is located at the end of the symmetrical cable body 113 away from the mounting cylinder 103. The retaining seat 105 is fixedly connected to one end of the fixing ring 101. The two fixing components are respectively disposed on the retaining ring 102 and the fixing ring 101. At both ends of 1, after the two symmetrical cable bodies 113 are connected, the sliding ring 104 is slid, and the sliding ring 104 and the retaining ring 102 move towards one end of the retaining seat 105, so that the retaining ring 102 is inserted into the retaining seat 105, and one end of the retaining ring 102 is in contact with the fixing ring 101. At this time, the retaining ring 102 and the retaining seat 105 are connected and fixed by the two fixing components. The retaining ring 102 and the retaining seat 105 seal and protect the connection of the two symmetrical cable bodies 113, ensuring that the two symmetrical cable bodies 113 will not break due to external force, thereby improving the stability of the cable connection.

[0021] Furthermore, the fixing clamp 110 is fixedly connected to one end of the fixing ring 101, the fixing block 108 is fixedly connected to the retaining ring 102, the limiting rod 115 is slidably connected to the fixing clamp 110 and passes through the fixing clamp 110, and the telescopic kit is disposed on the fixing clamp 110 and the limiting rod 115.

[0022] Furthermore, the movable block 111 is fixedly connected to one end of the limiting rod 115, and the two ends of the telescopic spring 112 are fixedly connected to the movable block 111 and the fixed clamping block 110 respectively, and the limiting rod 115 is located inside the telescopic spring 112.

[0023] In this embodiment, after the two symmetrical cable bodies 113 are connected, the two limiting rods 115 are pulled outwards respectively, causing the two limiting rods 115 to separate from the two fixing blocks 110. The two telescopic springs 112 are in a stretched state. At this time, the sliding ring 104 is slid, and the sliding ring 104 and the retaining ring 102 move towards one end of the retaining seat 105, so that the retaining ring 102 is inserted into the retaining seat 105, and one end of the retaining ring 102 is in contact with the fixing ring 101. At this time, the two fixing blocks 108 move to the two... Inside the fixed clamping block 110, the two limiting rods 115 are aligned with the two limiting holes 109 respectively. When the two limiting rods 115 are released, the two telescopic springs 112 return to their original position and retract, respectively driving the two limiting rods 115 to insert into the two limiting holes 109. This connects and fixes the retaining ring 102 and the retaining seat 105. The retaining ring 102 and the retaining seat 105 seal and protect the connection between the two symmetrical cable bodies 113, ensuring that the two symmetrical cable bodies 113 will not break under external force, thereby improving the stability of the cable connection.

[0025] In this embodiment, when the sliding ring 104 slides on the mounting cylinder 103, the two sliders 107 slide in the two sliding grooves 106 respectively, which limit and guide the movement of the sliding ring 104, ensuring that the two fixing blocks 108 can move into the two fixing clamps 110 respectively.

[0026] Furthermore, the flame-retardant layer 114 is fixedly connected to the symmetrical cable body 113 and is located on the outer side wall of the symmetrical cable body 113.

[0027] In this embodiment, the flame-retardant layer 114 can reduce the risk of combustion of the symmetrical cable body 113, thereby improving the safety of the symmetrical cable body 113.

[0028] When using this invention to protect the connection between the two symmetrical cable bodies 113, pull the two limiting rods 115 outwards respectively, causing the two limiting rods 115 to separate from the two fixing blocks 110. The two telescopic springs 112 are in a stretched state. At this time, slide the sliding ring 104. The sliding ring 104 and the retaining ring 102 move towards one end of the retaining seat 105, so that the retaining ring 102 is inserted into the retaining seat 105, and one end of the retaining ring 102 is in contact with the fixing ring 101. At this time, the two fixing blocks 108 move to the two... Inside the fixing clamp 110, the two limiting rods 115 are aligned with the two limiting holes 109 respectively. When the two limiting rods 115 are released, the two telescopic springs 112 return to their original position and retract, respectively driving the two limiting rods 115 to insert into the two limiting holes 109, thereby connecting and fixing the retaining ring 102 and the retaining seat 105. The retaining ring 102 and the retaining seat 105 seal and protect the connection of the two symmetrical cable bodies 113, ensuring that the two symmetrical cable bodies 113 will not break under external force, thereby improving the stability of the cable connection.
