Description

Technical Field

[0001] This utility model relates to the field of USB interface technology, and in particular to an improved USB interface structure to prevent misinsertion. Background Technology

[0002] USB (Universal Serial Bus) is a standardized interface technology for connecting computers to external devices, designed to simplify device connections, improve data transfer efficiency, and support plug-and-play functionality.

[0003] Traditional power strips with USB ports typically have a spring-loaded slider inside the USB port. Under normal conditions, the spring's force causes a protective plate to shield the conductive contacts inside the USB port, preventing accidental insertion by children. However, after repeated insertions and removals, the spring is prone to fatigue and failure, resulting in a decrease in the slider's reset accuracy. Since the spring is located inside the USB port, it is inconvenient to replace it when it fails, thus reducing the effectiveness of accidental insertion protection. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as traditional power strips with USB ports that typically use a spring-loaded slider inside the USB port. Under normal conditions, the spring's thrust causes a protective plate to shield the conductive contacts inside the USB port, thus preventing accidental insertion by children. However, after repeated insertions and removals, the spring is prone to fatigue and failure, leading to a decrease in the slider's reset accuracy. Since the spring is located inside the USB port, it is inconvenient to replace when it fails, reducing the effectiveness of accidental insertion protection. Therefore, this invention proposes an improved USB interface structure to prevent accidental insertion.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An improved USB interface structure to prevent mis-insertion includes a power strip, one end of which has a USB port at the top. A receiving plate is fixedly provided on the top end of the power strip, and the receiving plate is provided with an anti-mis-insertion mechanism. The anti-mis-insertion mechanism can block the USB port to prevent mis-insertion. To continuously prevent the USB port from being mis-inserted, a limiting mechanism is also included. This limiting mechanism can restrict the mis-insertion prevention mechanism and is easy to replace.

[0006] In one possible design, the anti-misinsertion mechanism includes a stop plate and a spring. The receiving plate has a first groove to facilitate the movement of the stop plate. The bottom of the stop plate is slidably connected to the bottom inner wall of the first groove. The top of the receiving plate has a groove, and the spring is placed in the groove. A moving hole is formed between the first groove and the groove. A connecting plate is slidably connected to the inner wall of the moving hole. One side of the connecting plate is fixedly connected to one side of the stop plate. The two ends of the spring abut against the sides of the connecting plate and the groove that are close to each other.

[0007] In one possible design, the limiting mechanism includes a baffle for limiting the spring, two insert plates, and two screws. The baffle is placed on top of the receiving plate and has a notch forming a U-shape. The tops of the two insert plates are fixedly connected to the bottom sides of the baffle, respectively. The receiving plate has slots on both sides of its top, into which the insert plates are inserted. The receiving plate has threaded holes on both sides for use with the screws, and the threaded holes are connected to the slots. The two screws are threadedly connected to the two threaded holes, respectively. The insert plates have insertion holes, into which one end of the screw is inserted.

[0008] In one possible design, a rubber pad is placed on the USB port for shielding when not in use, and a rubber plug is fixedly installed on one side of the bottom of the rubber pad. The rubber pad and the plug together form a shielding pad, which is adapted to the USB port.

[0009] In one possible design, a rubber pad is fixedly provided at one end of the baffle, and a pull plate is fixedly provided at the top of the other end of the baffle to facilitate the movement of the baffle. The pull plate is located within a notch in the baffle.

[0010] In one possible design, a connecting strap for preventing the shielding pad from being lost is fixedly provided on one side of the receiving plate, one end of the connecting strap is fixedly connected to one side of the shielding pad, and the connecting strap is made of rubber.

[0011] In this application, when no external force is applied, the spring pushes the connecting plate and the stop plate forward. The stop plate covers part of the USB port to prevent children from inserting the plug, thus preventing accidental insertion. In use, pinch the pull plate with your fingers and pull the stop plate backward, causing it to slide along the first groove. The spring is compressed, and after the stop plate moves, the USB port is exposed, allowing the correct USB plug to be inserted. Align the USB plug with the USB port and insert it in the correct direction. After insertion, release the pull plate. The stop plate moves under the action of the spring, but at this point, the plug occupies the port, and the stop plate does not obstruct device use. The stop plate rests against one side of the plug. When the USB port is not in use, pull the pull plate to move the stop plate away from the USB port, align the insert block at the bottom of the rubber pad with the USB port, and gently press to insert the insert block into the port. The rubber pad completely covers the port. To prevent dust or foreign objects from entering, loosen the pull plate. The retaining plate, propelled by a spring, will push above the rubber pad to provide support. Since the retaining pad is compatible with the USB port, it will not damage the internal components of the USB port. When the spring needs replacement, use a screwdriver to turn the screw counterclockwise to remove it from the socket. Lift the retaining plate upwards, and the socket will be pulled out of the slot. After removing the retaining plate, remove the old spring from the groove and replace it with a new spring (the spring is placed between the connecting plate and the groove). Then install the retaining plate, aligning the socket with the slot and inserting it, ensuring the socket is fully inserted. Use a screwdriver to turn the screw clockwise to insert it into the socket of the socket, securing the retaining plate. The material and specifications of the spring can be selected according to actual needs. Double-sided tape can be used to fix the receiving plate and the power strip; specific options can be chosen based on requirements.

[0012] The beneficial effects of this utility model are as follows: In this utility model, the improved USB interface structure for preventing misinsertion achieves quick disassembly and replacement of the spring through a limiting mechanism and a combination of a baffle, a plug plate, and screws, without damaging the overall structure of the power strip. In this utility model, the improved USB interface structure for preventing accidental insertion uses a combination design of a baffle and a rubber pad. Under normal conditions, the baffle covers part of the USB port, effectively preventing children from accidentally inserting the device and avoiding the risk of electric shock or device damage. In this invention, the spring can be quickly disassembled and replaced through the limiting mechanism without damaging the overall structure of the power strip, thus improving the protection against accidental insertion. The anti-accidental insertion mechanism effectively prevents children from accidentally inserting USB ports, avoiding the risk of electric shock or device damage. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] In one embodiment: Refer to Figure 1-5 An improved structure, applied in the field of USB interfaces, includes: a USB port 4 is provided at the top of one end of a power strip 1, and a receiving plate 5 is fixedly mounted on the top of the power strip 1. The receiving plate 5 integrates an anti-misinsertion mechanism and a limiting mechanism, forming a modular protective structure.

[0017] The anti-misinsertion mechanism includes a stop plate 8, a spring 12, and a connecting plate 13. A groove is formed on the top of the receiving plate 5, and the spring 12 is placed in the groove; a first groove 11 is formed on the side of the receiving plate 5, and the bottom of the stop plate 8 is slidably connected to the inner wall of the first groove 11; the first groove 11 and the groove are connected through a moving hole 16, and the connecting plate 13 passes through the moving hole 16, with one end fixedly connected to the stop plate 8 and the other end abutting against the spring 12.

[0018] Limiting mechanism: includes baffle 2, insert plate 14 and screw 9. Baffle 2 has a U-shaped structure, with insert plate 14 fixed on both sides of the bottom. Insert plate 14 is inserted into slot 15 at the top of receiving plate 5. Threaded holes are opened on both sides of receiving plate 5, which are connected to slot 15. Screw 9 is screwed into the threaded holes and inserted into the insertion hole of insert plate 14 to fix baffle 2.

[0019] Under normal conditions, spring 12 pushes connecting plate 13 and stop plate 8 forward. Stop plate 8 covers part of the USB port 4 area, and rubber pads contact the edge of the port to form a physical barrier to prevent children from accidentally inserting the USB port.

[0020] In use, the user pinches the pull plate 7 with their fingers and pulls it backward. The stop plate 8 slides along the first groove 11, the spring 12 is compressed, and the USB port 4 is exposed. After inserting the USB plug in the correct orientation, the user releases the pull plate 7. The stop plate 8 returns to its original position under the action of the spring 12, but the plug has already occupied the port, so the stop plate 8 will not obstruct the use of the device.

[0021] The baffle 2 is fixed to the top of the receiving plate 5 by the insert plate 14 and screws 9, limiting the displacement of the spring 12 and ensuring the stable operation of the anti-misinsertion mechanism. The U-shaped notch design of the baffle 2 provides operating space for the pull plate 7 while avoiding interference with the movement of the stop plate 8.

[0022] Use a screwdriver to turn screw 9 counterclockwise to remove it from the socket of insert plate 14. Lift baffle 2 upwards, and insert plate 14 will be pulled out of slot 15, exposing spring 12 in the groove. Remove the old spring 12 and replace it with a new spring 12, ensuring that both ends of spring 12 are in contact with connecting plate 13 and the inner wall of the groove, respectively. Reinsert insert plate 14 into slot 15 and use a screwdriver to turn screw 9 clockwise to insert it into the socket of insert plate 14, securing baffle 2.

[0023] This application is for the field of USB interfaces, but can also be used in other fields where this application applies.

[0024] In another embodiment: Reference Figure 1-5 An improved USB interface structure to prevent mis-plugging: A rubber insert 6 is fixed to one side of the bottom of the rubber pad 3, and the two together form a shielding pad that is compatible with the size of the USB port 4. A rubber connecting strip 10 is fixed to the side of the receiving plate 5, with one end connected to one side of the shielding pad to prevent the shielding pad from being lost.

[0025] When USB port 4 is not in use, the user pulls the pull plate 7 to remove the stop plate 8, aligns the insert block 6 of the shielding pad with the USB port 4, and inserts it. The rubber pad 3 completely covers the port to prevent dust or foreign objects from entering. The rubber material of the shielding pad is soft and will not damage the conductive contacts inside the port.

[0026] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
