Description

Technical Field

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

[0002] Data cables are used to connect mobile devices and computers to achieve data transmission or communication. Simply put, they are the pathways connecting computers and mobile devices to transfer files such as videos, ringtones, and pictures. Now, with the rapid development of the electronics industry, data cables have become an indispensable part of our lives. Existing data cables simply involve inserting the connector pins directly into the device. With repeated plugging and unplugging, both the device's connector and the data cable pins will experience varying degrees of wear, potentially leading to problems such as poor contact later on. Summary of the Invention

[0003] In view of this, the present invention aims to provide a data cable that solves the technical problem that, with the increase of the number of plugging and unplugging cycles, both the device's connector and the data cable's pins will suffer varying degrees of wear, which may lead to subsequent poor contact.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a data cable, including a cable and a plug, with plugs at both ends of the cable, each plug including a transmission component, the transmission component being disposed on a mounting plate, the transmission component being connected to the cable, a fixing cylinder being disposed on the mounting plate, the cable being disposed on the fixing cylinder, and a driving component being slidably disposed on the fixing cylinder, the driving component driving the transmission component to expand and fix itself on the device or retract and detach from the device.

[0005] Furthermore, the transmission component includes a pin, a connecting piece slidably disposed inside the pin, a return spring disposed between the pin and the connecting piece, and a movable column slidably disposed inside the pin. The drive component pushes the movable column through the connecting rod to squeeze the connecting piece out from inside the pin for connection and fixation.

[0006] Furthermore, the connecting piece is a beveled arc-shaped piece, which is thicker closer to the insertion end of the pin, and the moving column is a trapezoidal column with a rotating bead on it.

[0007] Furthermore, the mounting plate is equipped with a fixing seat, and the drive assembly and the fixing seat cooperate to lock the connecting rod.

[0008] Furthermore, the driving assembly includes a first sliding sleeve slidably disposed on the fixed cylinder, a second sliding sleeve connected by a connecting plate, the second sliding sleeve slidably disposed on a sliding column, the sliding column being disposed on a connecting rod, and the sliding column being slidably disposed on a fixed seat. The sliding second sliding sleeve presses and limits the component on the fixed seat to prevent the sliding column from moving away from the pin.

[0009] Furthermore, the limiting component includes a movable ball end post, which is slidably disposed inside a sliding post. A first spring is provided between the movable ball end post and the sliding post. A limiting block is slidably disposed inside the sliding post. A second spring is provided between the limiting block and the movable ball end post. The limiting block prevents the sliding post from moving away from the insert pin.

[0010] Furthermore, the fixing seat includes a seat body, which is mounted on the mounting plate via a connecting rod. The seat body is provided with a sloping groove, the sloping surface of which faces the pin. The limiting block is a sloping block that cooperates with the sloping groove.

[0011] Furthermore, the second sliding sleeve has an annular groove inside, and after the moving ball end post enters the annular groove, the limiting block slides out from inside the inclined groove.

[0012] Beneficial effects: When the plug is inserted into the device's socket, the size of the transmission component is smaller than the size of the socket. Then, by pushing the drive component to slide on the fixed cylinder, the transmission component changes shape, increasing its size and firmly fixing itself inside the socket. When it is necessary to unplug the plug, simply moving the drive component in a certain direction will allow the transmission component to return to its original state and be easily removed.

[0014] As shown in the figure, a data cable includes a cable 1 and a plug 2. Both ends of the cable 1 are provided with plugs 2. The plug 2 includes a transmission component 4. The transmission component 4 is disposed on a mounting plate 3 and is connected to the cable 1. The mounting plate 3 is provided with a fixing cylinder 6. The cable 1 is disposed on the fixing cylinder 6. A driving component 7 is slidably disposed on the fixing cylinder 6. The driving component 7 drives the transmission component 4 to expand and fix itself on the device or retract and detach from the device.

[0015] When plug 2 is inserted into the device's socket, the size of the transmission component 4 is smaller than the size of the socket. Then, by pushing the drive component 7 to slide on the fixed cylinder 6, the transmission component 4 changes shape, increasing its size and firmly fixing itself inside the socket. When plug 2 needs to be removed, moving the drive component 7 in a certain direction will allow the transmission component 4 to return to its original state and be easily removed.

[0016] In this embodiment, the transmission component 4 includes a pin 4-1, a connecting piece 4-2 slidably disposed inside the pin 4-1, a return spring 4-3 disposed between the pin 4-1 and the connecting piece 4-2, and a moving post 4-4 slidably disposed inside the pin 4-1. The driving component 7 pushes the moving post 4-4 through the connecting rod 4-6 to squeeze the connecting piece 4-2 out of the pin 4-1 for connection and fixation. The connecting piece 4-2 is a beveled arc-shaped piece, which is thicker closer to the insertion end of the pin 4-1. The moving post 4-4 is a trapezoidal post, and a rotating bead 4-5 is disposed on the moving post 4-4.

[0017] The connecting rod 4-6 is pushed by the drive assembly 7 to move into the insert 4-1. The moving connecting rod 4-6 drives the moving column 4-4 to move. The trapezoidal column 4-4 pushes the connecting piece 4-2, which is a sloping arc-shaped piece, outward to slide out from the insert 4-1 and then make contact with the inner wall of the socket. The rotating bead 4-5 reduces the friction between the moving column 4-4 and the connecting piece 4-2 during sliding.

[0018] In this embodiment, the mounting plate 3 is provided with a fixed seat 9. The drive assembly 7 and the fixed seat 9 cooperate to lock the connecting rod 4-6. The drive assembly 7 includes a first sliding sleeve 7-1, which is slidably disposed on the fixed cylinder 6. A second sliding sleeve 7-3 is connected by a connecting plate 7-2 and is slidably disposed on a sliding post 7-5. The sliding post 7-5 is disposed on the connecting rod 4-6 and is slidably disposed on the fixed seat 9. The sliding second sliding sleeve 7-3 presses against the limiting assembly, which acts on the fixed seat 9 to prevent the sliding post 7-5 from moving away from the pin 4-1. The limiting assembly includes a movable ball end post 7-6, which is slidably disposed inside the sliding post 7-5. A first spring 7-7 is provided between the ball end post 7-6 and the sliding post 7-5. A limiting block 7-8 is slidably provided inside the sliding post 7-5. A second spring 7-9 is provided between the limiting block 7-8 and the movable ball end post 7-6. The limiting block 7-8 prevents the sliding post 7-5 from moving away from the insert pin 4-1. The fixed seat 8 includes a seat body 8-1, which is mounted on the mounting plate 3 via a connecting rod 8-2. The seat body 8-1 is provided with a sloping groove 8-3, the sloping surface of which faces the insert pin 4-1. The limiting block 7-8 is a sloping block that cooperates with the sloping groove 8-3. The second sliding sleeve 7-3 is provided with an annular groove 7-4 inside. After the movable ball end post 7-6 enters the annular groove 7-4, the limiting block 7-8 slides out from inside the sloping groove 8-3.

[0019] After plug 2 is inserted into the socket, pin 4-1 enters the socket. Then, the first sliding sleeve 7-1 is pushed to move closer to pin 4-1. The moving first sliding sleeve 7-1 causes the second sliding sleeve 7-3 to slide together. The moving second sliding sleeve 7-3 moves until its inner wall contacts the moving ball end post 7-6, thereby pushing the moving ball end post 7-6 into the sliding post 7-5. The moving moving ball end post 7-6 causes the limiting block 7-8 to limit the movement. The block enters the inclined groove 8-3. When the second sliding sleeve 7-3 can no longer slide on the sliding post 7-5, the second sliding sleeve 7-3 will push the sliding post 7-5 to slide on the seat 8-1. The moving sliding post 7-5 drives the connecting rod 4-6 to slide and drive the transmission component 4 to make a fixed connection. At the same time, the moving ball end post 7-6 and the limiting block 7-8 move together. Since the inclined surface of the inclined groove 8-3 faces the pin 4-1, the limiting block 7-8 then moves with the moving ball end post 7-6. While moving, it cannot move away from the pin 4-1, so that the transmission component 4 will not be disconnected when it is fixed in place without external force. When it is necessary to pull out the plug 2, the first sliding sleeve 7-1 is pulled in the opposite direction. The first sliding sleeve 7-1 away from the pin 4-1 drives the second sliding sleeve 7-3 to slide. The second sliding sleeve 7-3 slides to the annular groove 7-4 and is placed above the moving ball end post 7-6. Then the compressed first spring 7-7 drives the moving ball end post 7-6 to slide into the annular groove 7-4, so that the limiting block 7-8 slides out from the inclined groove 8-3. Then, when the first sliding sleeve 7-1 is pulled again, the first sliding sleeve 7-1 will drive the sliding post 7-5 to push away from the pin 4-1 through the second sliding sleeve 7-3. The sliding post 7-5 drives the connecting rod 4-6 to slide. The connecting rod 4-6 drives the moving post 4-4 to slide, reducing the pressure on the connecting piece 4-2, so that the pin 4-1 returns to its original state and the plug 2 can be easily pulled out.
