Description

Technical Field

[0001] The utility model relates to the technical field of USB jacks, in particular to a self-locking USB jack. Background Art

[0002] A USB jack, namely a USB interface, is a commonly used connection interface between a computer and other electronic devices. USB is the abbreviation of "Universal Serial Bus". Its initial design is to provide a standard interface so that various devices (such as mice, keyboards, printers, scanners, cameras, storage devices, etc.) can be conveniently connected to a computer and achieve data transmission and power supply.

[0003] However, traditional USB plugs have the problem of falling off during use, which not only brings inconvenience to users, but also may damage the USB interface due to frequent plugging and unplugging, reducing its service life. To solve this problem, a self-locking USB jack has emerged. It not only effectively prevents the plug from falling off, but also significantly improves the service life and usability of the USB interface.

[0004] When using an existing USB socket, the plug needs to be inserted into it. However, since the plug is connected to a data cable or a USB flash drive, when it is in use, if the data cable or the USB flash drive is collided, it will drive the plug to shake, thereby loosening the connection between the plug and the socket, affecting data transmission, and thus affecting people's work and entertainment. Content of the Utility Model

[0005] The purpose of this application is to provide a self-locking USB jack to solve the problem that traditional USB plugs are prone to falling off, which in turn affects people's entertainment and work.

[0006] To achieve the above purpose, this application specifically adopts the following technical solutions:

[0007] A self-locking USB jack includes a socket. A plug is slidably arranged in the socket. A barb is slidably arranged in the socket. A positioning hole is formed on the plug, and the positioning hole is adapted to the barb. A self-locking structure is arranged on the socket.

[0008] By adopting the above technical solution, when using this socket to connect to a plug, first insert the plug into the socket, move the positioning hole on it to the position of the barb, and then drive the barb into the positioning hole through the self-locking structure to position the plug. At the same time, the self-locking structure will push the plug to make the positioning hole on it and the barb more tightly limited. When it is necessary to remove the plug, the self-locking structure can loosen the plug to make it leave the positioning hole, making the insertion and removal and positioning of the plug more convenient, making the plug more stable when inserted into this socket, and enabling personnel to better protect the work and entertainment processes during use.

[0009] Further, the self-locking structure includes an adjustment box connected to the socket. A button is slidably connected to the adjustment box. A fixed column is fixedly connected to the socket. A rocker is rotatably connected to the fixed column. One end of the rocker is hinged to the barb, and the end of the rocker away from the barb is hinged to the button.

[0010] By adopting the above technical solution, when it is necessary to remove the plug, press the button to move it downward, thereby pushing one end of the rocker to sink, making the end connected to the barb rise, driving the barb to move out of the positioning hole. At this time, pulling out the plug can release the limiting relationship between the plug and the socket.

[0011] Further, a return spring is fixedly connected to the socket. The end of the return spring is fixedly connected to the rocker.

[0012] By adopting the above technical solution, push the barb to move into the adjustment box. When its positioning hole moves to the lower end of the barb, at this time the spring returns to push the end of the rocker upward, making the other end of the rocker move downward and inserting the barb into the positioning hole.

[0013] Further, a support plate is slidably connected inside the socket. A telescopic rod is fixedly connected inside the socket. The end of the telescopic rod is fixedly connected to the support plate.

[0014] By adopting the above technical solution, when the plug is inserted into the socket, its end pushes the support plate to move inward into the socket to limit the insertion position of the plug.

[0015] Further, a limiting spring is sleeved on the telescopic rod. The two ends of the limiting spring are respectively fixedly connected to the support plate and the socket.

[0016] By adopting the above technical solution, the limiting spring returns to push the support plate to move outward from the socket, and the telescopic rod also extends accordingly. When pushing the plug outward, it will make the positioning hole move outward, making the positioning hole and the barb more tightly in contact with each other.

[0017] Furthermore, a guide bar is fixedly connected to the support plate, a guide block is fixedly connected to the end of the guide bar, a guide groove is provided inside the socket, and the guide groove is slidably connected to the guide block.

[0018] By adopting the above technical solution, the movement of the support plate is limited by the movement of the guide block in the guide groove, so that the movement of the plug pushed by the support plate is more stable.

[0019] Furthermore, a rotating column is fixedly connected to the support plate, a side plate is rotatably connected to the rotating column, a clamping strip is provided on the side plate for connection, and the side plate is adapted to the plug.

[0020] By adopting the above technical solution, the side plates of the support plate are also driven to move toward the inside of the socket, so that when the side plates are released to the socket, the two side plates are rotated toward each other and the ends of the plug are limited from both sides.

[0021] Furthermore, a torsion spring is sleeved on the rotating column, and two ends of the torsion spring are respectively fixedly connected to the side plate and the supporting plate.

[0022] By adopting the above technical solution, the torsion spring reset drives the side plate to rotate in the opposite direction along the rotating column to reset, which facilitates the next limiting of the side plate on the end of the plug.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] When the plug is inserted into the socket, the plug pushes the barb to move into the adjustment box during the insertion process. When the positioning hole moves to the lower end of the barb, the spring resets and pushes the end of the seesaw to move upward, so that the other end of the seesaw moves downward, and the barb is inserted into the positioning hole to limit the positioning hole. When the U disk or data cable connected to the plug is collided during use, the plug can be restricted by the barb, reducing the space for its shaking, thereby protecting the plug and the socket from being easily interrupted by external interference during use. When the plug needs to be taken out, press the button to move it downward, thereby pushing one end of the seesaw to sink, so that the end connected to the barb rises, driving the barb to move from the positioning hole. At this time, pulling out the plug can release the limiting relationship between the plug and the socket, which makes the device more convenient during use.

[0025] 2. In the present application, when the plug is inserted into the socket, its end pushes the support plate to move inside the socket. When the barb limits the positioning hole, the plug is loosened. At this time, the limiting spring resets and pushes the support plate to move outside the socket. The telescopic rod also extends, and when the plug is pushed outward, the positioning hole moves outward, so that the positioning hole and the barb are more tightly in contact with each other, further strengthening the limiting effect between the plug and the socket. The movement of the support plate is limited by the movement of the guide block in the guide groove, so that the movement of the plug pushed by the support plate is more stable, and the plug is pushed by the push plate during the removal process, so it can be taken out more conveniently.

[0032] The following is combined with Figures 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a self-locking USB socket.

[0034] Reference Figure 1 and Figure 2 A self-locking USB socket comprises a socket 1, a plug 2 is slidably arranged in the socket 1, a barb 5 is slidably arranged in the socket 1, a positioning hole 18 is opened on the plug 2, the positioning hole 18 is adapted to the barb 5, and a self-locking structure is arranged on the socket 1.

[0035] When using this socket 1 to connect the plug 2, first insert the plug 2 into the socket 1, so that the positioning hole 18 on it moves to the position of the barb 5, and then drive the barb 5 into the positioning hole 18 through the self-locking structure to position the plug 2. At the same time, the self-locking structure will push the plug 2 to make the positioning hole 18 on it and the barb 5 more tightly limited. When it is necessary to remove the plug 2, the self-locking structure can loosen the plug 2 to make it leave the positioning hole 18, making the plugging and unplugging and positioning of the plug 2 more convenient, making the plug 2 more stable when inserted on this socket 1, and enabling personnel to better protect the working and entertainment processes during use.

[0036] Refer to Figure 2 And Figure 3 As shown in the figure, the self-locking structure includes an adjustment box 3 connected to the socket 1. A button 4 is slidably connected to the adjustment box 3. A fixed column 15 is fixedly connected to the socket 1. A rocker 16 is rotatably connected to the fixed column 15. One end of the rocker 16 is hinged to the barb 5, and the end of the rocker 16 away from the barb 5 is hinged to the button 4. A return spring 17 is fixedly connected to the socket 1, and the end of the return spring 17 is fixedly connected to the rocker 16.

[0037] When the plug 2 is inserted into the plug 2, during the insertion process, the plug 2 pushes the barb 5 to move into the adjustment box 3. When its positioning hole 18 moves to the lower end of the barb 5, at this time, the spring returns to push the end of the rocker 16 to move upward, so that the other end of the rocker 16 moves downward, inserting the barb 5 into the positioning hole 18 to limit the positioning hole 18. Thus, when the U disk or data cable connected to the plug 2 is collided during the use of the plug 2, the plug 2 can be restricted by the barb 5, reducing its shaking space, thereby protecting the plug 2 and the socket 1 from being interrupted by external interference during use. When it is necessary to remove the plug 2, press the button 4 to make it move downward, thereby pushing one end of the rocker 16 to sink, making the end connected to the barb 5 rise, driving the barb 5 to move out of the positioning hole 18. At this time, pulling out the plug 2 can release the limiting relationship between the plug 2 and the socket 1, making the device more convenient to use during the use process.

[0038] Refer to Figure 2 And Figure 4 As shown in the figure, a tray 8 is slidably connected inside the socket 1. A telescopic rod 6 is fixedly connected inside the socket 1, and the end of the telescopic rod 6 is fixedly connected to the tray 8. A limiting spring 7 is sleeved on the telescopic rod 6, and both ends of the limiting spring 7 are fixedly connected to the tray 8 and the socket 1 respectively. A guide bar 9 is fixedly connected to the tray 8, and a guide block 10 is fixedly connected to the end of the guide bar 9. A guide groove is opened inside the socket 1, and the guide groove is slidably connected to the guide block 10.

[0039] When the plug 2 is inserted into the socket 1, its end pushes the support plate 8 to move inside the socket 1. When the barb 5 limits the positioning hole 18, the plug 2 is loosened. At this time, the limit spring 7 resets and pushes the support plate 8 to move outside the socket 1. The telescopic rod 6 also extends, and when the plug 2 is pushed outward, the positioning hole 18 moves outward, so that the positioning hole 18 and the barb 5 are more closely in contact with each other, further strengthening the limiting effect between the plug 2 and the socket 1. The movement of the guide block 10 in the guide groove limits the movement of the support plate 8, so that the movement of the plug 2 pushed by the support plate 8 is more stable, and the plug 2 is pushed by the push plate during the removal process, so that it can be more convenient to take out.

[0040] Reference Figure 2 and Figure 4 The support plate 8 is fixedly connected with a rotating column 12, and the rotating column 12 is rotatably connected with a side plate 11, and the side plate 11 is provided with a clamping strip 14, and the side plate 11 is adapted to the plug 2. The rotating column 12 is sleeved with a torsion spring 13, and the two ends of the torsion spring 13 are fixedly connected with the side plate 11 and the support plate 8 respectively.

[0041] When the plug 2 pushes the support plate 8 to move into the socket 1, the side plate 11 of the support plate 8 is also moved toward the inside of the socket 1, so that when the side plate 11 is released to the socket 1, the two side plates 11 are rotated toward opposite sides and the ends of the plug 2 are limited from both sides, further enhancing the stability of the plug 2 in the socket 1. After the plug 2 is taken out, the torsion spring 13 is reset to drive the side plate 11 to rotate in the opposite direction along the rotating column 12 for reset, which facilitates the next time the side plate 11 limits the end of the plug 2.

[0042] Working principle: when the plug 2 is inserted into the plug 2, the plug 2 pushes the barb 5 to move into the adjustment box 3 during the insertion process. When its positioning hole 18 moves to the lower end of the barb 5, the spring reset pushes the end of the seesaw 16 to move upward, so that the other end of the seesaw 16 moves downward, and the barb 5 is inserted into the positioning hole 18, so that it limits the positioning hole 18, so that when the U disk and data cable connected to the plug 2 are collided during use, the plug 2 can be limited by the barb 5, reducing the space for its shaking, thereby protecting the plug 2 and the socket 1 from being easily interrupted by external interference during use. When the plug 2 needs to be taken out, the button 4 is pressed to move it downward, thereby pushing one end of the seesaw 16 to sink, so that the end connected to the barb 5 rises, driving the barb 5 to move from the positioning hole 18, and at this time, the plug 2 can be pulled out to release the limiting relationship between the plug 2 and the socket 1, which makes the device more convenient during use;

[0043] When the plug 2 is inserted into the socket 1, the end thereof pushes the support plate 8 to move towards the inside of the socket 1. When the barb 5 limits the positioning hole 18, the plug 2 is loosened. At this time, the limit spring 7 resets and pushes the support plate 8 to move towards the outside of the socket 1, and the telescopic rod 6 also extends accordingly. When the plug 2 is pushed outwards, the positioning hole 18 will move outwards, making the positioning hole 18 contact the barb 5 more tightly, further strengthening the limiting effect between the plug 2 and the socket 1. Through the movement of the guide block 10 in the guide groove, the movement of the support plate 8 is limited, making the movement of the support plate 8 pushing the plug 2 more stable, and enabling the plug 2 to be more conveniently taken out under the push of the push plate during the pulling-out process;

[0044] When the plug 2 pushes the support plate 8 to move towards the inside of the socket 1, it drives the side plate 11 of the support plate 8 to also move towards the inside of the socket 1. When the side plate 11 touches the socket 1, the two side plates 11 rotate towards each other and limit the end of the plug 2 from both sides of the plug 2, further strengthening the stability of the plug 2 in the socket 1. After the plug 2 is taken out, the torsion spring 13 resets and drives the side plate 11 to rotate in the opposite direction along the rotating column 12 for resetting, facilitating the next limitation of the end of the plug 2 by the side plate 11.
