[0001] This utility model relates to the field of data cable technology, and in particular to a data cable. Background Technology

[0002] Data cables are extremely important transmission tools in the process of power and data transmission. With the continuous updating and development of electronic devices, the market requirements for data cables are also getting higher and higher. Users not only pay attention to the performance of the cables, but also pay more and more attention to their appearance. Data cables are generally used to connect to mobile phones. After connecting to a charging head, they can be charged. Now, with the rapid development of the electronics industry, data cables have become an indispensable part of our lives.

[0003] Existing data cables have connectors at both ends. The small connector is used to connect to mobile phones, and the large connector is used to connect to other electrical appliances, such as computers or chargers. However, when not in use, there is no device to protect the large connector, so dust can easily enter and wear out, resulting in poor contact and affecting use. Utility Model Content

[0004] Given that circulating fluidized bed boilers are divided into dense phase and dilute phase zones during combustion, but existing oxygen supply equipment cannot adjust the direction of oxygen supply depth and is uneven in oxygen supply, making it difficult to adapt to changes in fuel characteristics, reducing operational flexibility, and easily leading to excessive local oxygen supply, resulting in overheating and coking, thus reducing combustion efficiency, this utility model is proposed.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a data cable, including a large connector, a connecting wire at one end of the large connector, and a small connector at the end of the connecting wire away from the large connector. The connecting wire includes multiple sets of conductive wires connecting the large connector and the small connector. An insulating layer is wrapped around the outer wall of the conductive wire. A first shielding layer is wrapped around the outer wall of the insulating layer. A second shielding layer is wrapped around the outer wall of the first shielding layer. A reinforcing layer is wrapped around the outer wall of the second shielding layer. A protective layer is wrapped around the outer wall of the reinforcing layer. An outer sheath is wrapped around the outer wall of the protective layer. A protective component is fitted onto the outer wall of the large connector. The protective component includes a protective sleeve fitted onto the outer wall of the large connector. A bidirectional lead screw is inserted into the inner cavity of the protective sleeve. Two sets of symmetrical moving plates are fitted onto the outer wall of the bidirectional lead screw. A wedge is fixed at one end of the moving plates that is close to each other. A wedge opening that cooperates with the wedge is opened on the outer wall of the large connector.

[0006] In a preferred embodiment of the data cable of this utility model, the insulating layer is made of polyvinyl chloride, the first shielding layer is made of aluminum foil, the second shielding layer is made of tin-plated copper wire braided mesh, the reinforcing layer is made of Kevlar fiber, the protective layer is made of thermoplastic elastomer, and the outer sheath is made of polyester fiber.

[0007] In a preferred embodiment of the data cable of this utility model, the movable plate is movably inserted into the inner cavity of the protective sleeve, and the wedge is movably inserted into the inner wall of the wedge opening.

[0008] In a preferred embodiment of the data cable described in this utility model, the movable plate has a threaded hole that mates with the outer wall of the bidirectional lead screw, the bidirectional lead screw is rotatably inserted into the inner cavity of the protective sleeve, and the upper end of the bidirectional lead screw moves through the protective sleeve and is connected to a turntable.

[0009] In a preferred embodiment of the data cable of this utility model, a slide rod is fixedly provided at one end of the protective sleeve cavity and the bidirectional lead screw, and the movable plate is movably sleeved on the outer wall of the slide rod.

[0010] In a preferred embodiment of the data cable described in this utility model, the outer wall of the protective sleeve is provided with four sets of mutually symmetrical focusing holes, and a light-emitting element is fixedly inserted at the bottom of the focusing hole.

[0011] Compared with the prior art, the present invention has at least the following beneficial effects: In this invention, the large connector is inserted into the protective sleeve along the inner cavity of the protective sleeve. Then, the double-acting screw is rotated, and the two sets of moving plates move closer to each other. The wedge is gradually inserted into the wedge until the moving plates and the outer wall of the large connector are in contact and the double-acting screw cannot be rotated. At this point, the protective sleeve can be fitted onto the outer wall of the large connector. The protective sleeve provides protection for the large connector, not only preventing frictional damage from external objects, but also preventing dust from entering the large connector, thus increasing the service life of the large connector.

[0012] 2. In this utility model, the light-emitting component can emit fluorescence at night. The fluorescence emitted by the light-emitting component diffuses in all directions, but the light-emitting component is set in a focusing hole, so the focusing hole can concentrate the emitted fluorescence, making the fluorescence emitted in the focusing hole brighter in the dark and easier to find. In addition, there are focusing holes on all four sides of the outer wall of the protective cover, thereby reducing the possibility that the focusing holes are blocked by obstacles, making the protective cover easier to find. Thus, when the device needs to be used in poor lighting or dark environments, the user can determine the location of the device based on the light-emitting component, making the device easier to find.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example

[0016] Reference Figures 1-4 This is the first embodiment of the present invention, providing a data cable including a large connector 1, a connecting wire 3 at one end of the large connector 1, and a small connector 4 at the end of the connecting wire 3 away from the large connector 1. The connecting wire 3 includes multiple sets of conductive wires 31 connected between the large connector 1 and the small connector 4. The outer wall of the conductive wires 31 is wrapped with an insulating layer 32, the outer wall of the insulating layer 32 is wrapped with a first shielding layer 33, the outer wall of the first shielding layer 33 is wrapped with a second shielding layer 34, and the outer wall of the second shielding layer 34 is wrapped with... There is a reinforcing layer 35, and a protective layer 36 is wrapped around the outer wall of the reinforcing layer 35. An outer sheath 37 is wrapped around the outer wall of the protective layer 36. A protective component 5 is fitted on the outer wall of the large connector 1. The protective component 5 includes a protective sleeve 51 fitted on the outer wall of the large connector 1. A bidirectional lead screw 52 is inserted into the inner cavity of the protective sleeve 51. Two sets of symmetrical moving plates 53 are fitted on the outer wall of the bidirectional lead screw 52. A wedge 55 is fixed at one end of the moving plates 53 that is close to each other. A wedge 2 that cooperates with the wedge 55 is opened on the outer wall of the large connector 1.

[0017] The insulation layer 32 is made of polyvinyl chloride, the first shielding layer 33 is made of aluminum foil, the second shielding layer 34 is made of tin-plated copper wire braided mesh, the reinforcing layer 35 is made of Kevlar fiber, the protective layer 36 is made of thermoplastic elastomer, and the outer sheath layer 37 is made of polyester fiber. The insulation layer 32 wraps around each individual conductive wire 31 to prevent direct contact between conductive wires 31 that could cause a short circuit, ensuring safe current transmission. The first shielding layer 33 defends against high-frequency electromagnetic interference, preventing external interference signals from affecting data transmission quality. The second shielding layer 34 defends against low-frequency electromagnetic interference and provides physical protection, enhancing the cable's tensile strength. The reinforcing layer 35 bears tensile force, preventing the connecting wire 3 from breaking and significantly improving the cable's durability. The protective layer 36 wraps around the internal structure, providing basic insulation and abrasion protection, and the thermoplastic elastomer material is more environmentally friendly and soft. The outer sheath layer 37 further enhances abrasion resistance and tensile strength, making the cable more durable while improving its appearance and feel.

[0018] The movable plate 53 is movably inserted into the inner cavity of the protective sleeve 51, and the wedge 55 is movably inserted into the inner wall of the wedge 2.

[0019] The movable plate 53 has a threaded hole that matches the outer wall of the bidirectional lead screw 52. The bidirectional lead screw 52 is rotatably inserted into the inner cavity of the protective sleeve 51. The upper end of the bidirectional lead screw 52 moves through the protective sleeve 51 and is connected to a turntable.

[0020] A slide bar 54 is fixedly provided at one end of the inner cavity of the protective sleeve 51 and the bidirectional lead screw 52, ​​and a movable plate 53 is movably sleeved on the outer wall of the slide bar 54. As the movable plates 53 approach each other, the movable plates 53 slide along the slide bar 54, which increases the stability of the movable plates 53 during movement.

[0021] The outer wall of the protective sleeve 51 has four sets of symmetrical focusing holes 56. A light-emitting element 57 is fixedly inserted at the bottom of the focusing hole 56. The light-emitting element 57 can emit fluorescence at night. The fluorescence emitted by the light-emitting element 57 diffuses in all directions, but the light-emitting element 57 is set in the focusing hole 56, so the focusing hole 56 can concentrate the emitted fluorescence, making the fluorescence emitted in the focusing hole 56 more eye-catching in the dark and easier to find. Moreover, the four sides of the outer wall of the protective sleeve 51 are provided with focusing holes 56, thereby reducing the possibility that the focusing holes 56 are blocked by obstacles, making the protective sleeve 51 easier to find. Thus, when the device needs to be used in poor light or dark environments, the user can determine the location of the device based on the light-emitting element 57, making the device easier to find.

[0022] When the large connector 1 is not in use, insert the large connector 1 into the protective sleeve 51 along the inner cavity of the protective sleeve 51. Then rotate the double-acting screw 52. The double-acting screw 52 drives the two sets of moving plates 53 to slide along the outer wall of the double-acting screw 52 and the inner cavity of the protective sleeve 51, and the two sets of moving plates 53 move closer to each other. The wedge 55 is gradually inserted into the wedge 2 until the moving plate 53 and the outer wall of the large connector 1 are in contact and the double-acting screw 52 cannot be rotated. At this time, the protective sleeve 51 can be put on the outer wall of the large connector 1 and pulled outward. Under the limiting action of the wedge 55 and the wedge 2, the large connector 1 cannot be pulled out of the protective sleeve 51. The protective sleeve 51 provides protection for the large connector 1, not only avoiding friction damage to the large connector 1 from external objects, but also preventing dust from entering the large connector 1, thus increasing the service life of the large connector 1.
