Description

Technical Field

[0001] The utility model relates to the technical field of twisted-pair cables, in particular to a twisted-pair cable. Background Art

[0002] Twisted-pair cable is a transmission medium consisting of one or more twisted pairs of wires enclosed in an insulating jacket. It is currently the most commonly used wiring material for local area networks (LANs). It is often used in broadband networks and LANs to connect network endpoints, such as PCs, servers, switches, routers, and other devices. To reduce signal interference, each twisted pair in the cable is typically made up of two insulated copper conductors twisted around each other, hence the name twisted-pair cable.

[0003] In the patent document of a cable connector with the announcement number CN219458640U, there is disclosed a left connector and a right connector, wherein the front side of the left connector is plugged into the rear side of the right connector, the top and bottom of the left connector are fixedly connected with a matching block, and the top and bottom of the right connector are fixedly connected with a protrusion, the surfaces of the two matching blocks are slidably connected and in close contact with the inside of the two protrusions, a cavity is provided inside the top matching block, a clamping assembly is provided at the bottom of the inner wall of the cavity, and a pressing assembly is provided at the top of the inner wall of the cavity. The device is provided with structural components such as a left connector, a right connector, a matching block, a protrusion, a cavity and a clamping assembly. The use of the clamping assembly can fix the matching block and the protrusion, thereby achieving the fixation of the left connector and the right connector, and the use of the pressing assembly can move the two clamping blocks out of the inside of the matching block, thereby making the matching block disengage from the protrusion and achieving the separation of the left connector and the right connector, which has the advantage of being able to quickly disassemble and assemble the cable connector; however, the above patent document still has the following defects during implementation:

[0004] In an office or home environment, people may accidentally pull on a twisted-pair cable without noticing, causing the cable to shake or even become disconnected. Not only may the outer sheath of the cable be worn, but once the outer sheath is damaged, the internal twisted pair will be exposed and easily affected by the external environment (such as moisture and dust), further reducing the performance and service life of the cable. In addition, continuous shaking may cause the cable to be momentarily disconnected at the joint, resulting in a momentary interruption in data transmission, affecting the continuity and safety of production. Therefore, we propose a twisted-pair cable to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] Example 1

[0026] like Figure 1-5As shown, this embodiment provides a twisted pair cable, including a cable body 13 and an outer shell 1, a connecting tube 11 is fixedly connected to the left side of the outer shell 1, a port 12 is provided on the right side of the outer shell 1, the cable body 13 is plugged into the connecting tube 11, a rotating cover 14 is rotatably connected to the top of the outer shell 1, a limiting component 2 is provided inside the outer shell 1, and a fixing component 3 is provided inside the connecting tube 11.

[0027] Among them, the cross-section of the cable body 13 is circular, and the cable core, isolation layer, shielding layer, and protective layer are arranged in sequence from the inside to the outside, and the isolation layer can further include one or more of a flame retardant layer, a waterproof layer, an insulating layer, and a thermal insulation layer, and the cable core includes several twisted pairs, and each twisted pair is formed by twisting two cores.

[0028] Specifically, in order to achieve the purpose of fixing the connected cables, refer to Figure 1 and Figure 3 In this embodiment, the fixing assembly 3 includes a sleeve 31, the inner wall of the sleeve 31 contacts the outer surface of the connecting pipe 11, the right outer surface of the connecting pipe 11 is provided with a thread, and the outer surface of the connecting pipe 11 is threadedly connected to a rotating block 32, and the left side of the rotating block 32 is rotatably connected to the right side of the sleeve 31.

[0029] For further information, see Figure 3 and Figure 4 In this embodiment, four oblique grooves are opened on the left side of the connecting tube 11, and the four oblique grooves are arranged in a circular array with the center of the connecting tube 11 as the circumference. The inner wall of the oblique groove is slidably connected to a limit plate 36, and the bottom of the limit plate 36 is set as an inclined surface. A clamping block 35 is fixedly connected to the left side of the limit plate 36, and the end of the clamping block 35 close to the center of the sleeve 31 contacts the outer surface of the cable body 13.

[0030] During the implementation process, when the cable body 13 is plugged into the plug, one end of the cable body 13 is first inserted into the shell 1 through the connecting tube 11. When the cable body 13 is connected, the turn block 32 is rotated counterclockwise. The turn block 32 will move to the left while rotating counterclockwise, and the turn block 32 will push the sleeve 31 to move to the left when it moves.

[0031] For further information, see Figure 4 and Figure 5 In this embodiment, the clamping block 35 is fixedly connected to one end away from the cable body 13 with two sliding rods 33, the outer surfaces of the two sliding rods 33 are slidably connected to the inner wall of the sleeve 31, and the two sliding rods 33 are fixedly connected to one end away from the cable body 13 with a connecting plate 34.

[0032] For further information, see Figure 5In this embodiment, springs 37 are sleeved on the outer surfaces of the two sliding rods 33, and the ends of the two springs 37 close to the cable body 13 are fixedly connected to the ends of the clamping block 35 away from the cable body 13, and the ends of the two springs 37 away from the cable body 13 are fixedly connected to the inner wall of the sleeve 31.

[0033] During implementation, as the sleeve 31 moves to the left, it will drive the limit plate 36 to move in the inclined groove opened on the left side of the connecting tube 11. As the limit plate 36 continues to move, the two springs 37 will push the clamping block 35 tightly against the surface of the cable body 13 due to the elastic force. The cable body 13 can be fixed through the four clamping blocks 35. When the cable body 13 is pulled and shakes, the cable body 13 will push the corresponding clamping block 35 due to inertia, causing the corresponding two springs 37 to deform, thereby buffering and offsetting the force of the cable body 13 shaking. It can not only limit the range of movement of the cable, reduce the friction between the cable and the connector or surrounding objects, avoid wear on the cable sheath, and improve the performance and service life of the cable, but also withstand a certain degree of shaking, ensuring that the connection between the cable and the connector is always in a conductive state, avoiding instantaneous interruption of data transmission, and affecting the continuity and safety of production.

[0034] Example 2

[0035] This embodiment sets a restriction component based on the first embodiment.

[0036] Specifically, in order to achieve the purpose of opening the rotating cover quickly and conveniently, refer to Figure 1 and Figure 2 In this embodiment, the limiting component 2 includes two movable plates 22, and the two movable plates 22 are symmetrically arranged with the center of the rotating cover 14. The bottom of the movable plate 22 is slidably connected to two slide rails 21, and the ends of the two slide rails 21 close to each other are fixedly connected to the outer surface of the shell 1.

[0037] For further information, see Figure 2 In this embodiment, a fixing block 25 is fixedly connected to the top of the movable plate 22 on the left side, and a connecting block 23 is fixedly connected to the top of the movable plate 22 on the right side.

[0038] For further information, see Figure 2 In this embodiment, the connecting block 23 is internally connected to a rotating rod 24, the left outer surface of the rotating rod 24 is provided with a thread, the left outer surface of the rotating rod 24 is threadedly connected to a nut 26, and the right side of the nut 26 contacts the left side of the fixed block 25.

[0039] During implementation, when the device is damaged and needs repair or maintenance, first turn the nut 26 counterclockwise to remove it from the outer surface of the rotating rod 24, rotate the rotating rod 24 to make it leave the inner wall of the fixed block 25, and push the two movable plates 22 to both sides to make them leave the top of the rotating cover 14 to release the restriction on the rotating cover 14, so that the rotating cover 14 can be directly rotated and opened. Not only can the rotating cover 14 be opened quickly and conveniently so that the network connection can be restored in time in an emergency, reducing the impact of network interruption on work or life, but it can also conveniently operate the connection part of the cable and the connector, thereby improving the efficiency of maintenance work.

[0040] When the cable body 13 is connected to the plug, the first end of the cable body 13 is inserted into the shell 1 through the connecting tube 11. When the cable body 13 is connected, the rotating block 32 is rotated counterclockwise. The rotating block 32 will move to the left while rotating counterclockwise. When the rotating block 32 moves, it will push the sleeve 31 to the left.

The cable body 13 can be fixed through the four clamping blocks 35. When the cable body 13 is pulled and shakes, the cable body 13 will push the corresponding clamping block 35 due to inertia, causing the corresponding two springs 37 to deform, thereby buffering and offsetting the force of the cable body 13 shaking, which can not only limit the cable The range of motion reduces the friction between the cable and the connector or surrounding objects, avoids wear of the cable sheath, improves the performance and service life of the cable, and can also withstand a certain degree of shaking, ensuring that the connection between the cable and the connector is always in a conductive state, avoiding instantaneous interruption of data transmission, affecting the continuity and safety of production. When the device is damaged and needs repair or maintenance, first turn the nut 26 counterclockwise to remove it from the outer surface of the rotating rod 24, turn the rotating rod 24 to make it leave the inner wall of the fixed block 25, and push the two movable plates 22 to both sides to make them leave the top of the rotating cover 14 to release the restriction on the rotating cover 14, so that the rotating cover 14 can be directly rotated to open, which not only can quickly and conveniently open the rotating cover 14 so that the network connection can be restored in time in an emergency, reducing the impact of network interruption on work or life, but also can conveniently operate the connecting part of the cable and the connector, thereby improving the efficiency of maintenance work.
