Description

Technical Field

[0001] This utility model relates to the field of anti-loosening USB socket technology, specifically to a structure for preventing USB plug loosening. Background Technology

[0002] USB ports in cars are a feature in modern cars designed to meet the charging needs of passengers' electronic devices. They are usually located next to the armrest or under the front seat and can charge devices such as dashcams and mobile phones. Some cars with fewer USB ports can even have their cigarette lighter converted into a USB port.

[0003] According to Chinese Patent Publication No. CN219843230U, "An Anti-Loosening Structure for a USB Plug," the structure mainly consists of a ring cover and a base that are detachably connected. The ring cover has a cavity into which the assembled USB plug and USB interface are placed. The ring cover is then installed on the circuit board where the USB interface is located. Finally, the base is horizontally inserted into the tail of the ring cover, thereby further pressing the USB plug and USB interface into the cavity. This enhances the connection strength of the USB plug and USB interface in environments with movement and vibration, solving the problem that universal USB male and female plugs are prone to loosening and affecting the normal operation of the device when used in environments with movement and vibration.

[0004] In actual use, the ports of common car USB slots are usually exposed, with no attachments on the port surface. During car driving, vibrations can cause the USB slot and USB plug to become loose or wobble, resulting in poor connection between the USB socket and plug. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a structure to prevent USB plug loosening, thereby improving the connection between the USB socket and the plug and reducing the likelihood of the plug becoming loose during vehicle operation.

[0006] This utility model provides a structure to prevent USB plug loosening, including connecting pieces. The connecting pieces are fixedly connected to the upper and lower sides of the socket by adhesive strips. Each of the two connecting pieces has an adaptation groove on its opposite side, and the adaptation groove contacts the plug. A retaining plate is fixedly connected to the connecting piece on the side of the adaptation groove. Two sealing plates are hinged to the end of the retaining plate away from the connecting piece. The sealing plate has a cable tray groove. Each of the two retaining plates has a limit groove on its opposite side. A rubber retaining block is fixedly connected to the side of the sealing plate near the adaptation groove.

[0007] Optionally, two gaskets are fixedly connected to the end of the card plate away from the limiting groove. The gaskets are made of rubber and have recesses corresponding to the limiting groove. By setting the gaskets, the friction is increased, which can improve the stability of the USB plug socket.

[0008] Optionally, a U-shaped clip is engaged with the limiting groove, and a positioning rod is threadedly connected to one side of the U-shaped clip. The U-shaped clip contacts the card plate. By setting the positioning rod, the stability of the connection between the U-shaped clip and the card plate is further increased.

[0009] Optionally, a fixing strip is fixedly connected to the side of the card plate away from the rubber block. One end of the fixing strip is fixedly connected to the end of the connecting piece away from the adhesive strip. By setting the fixing strip, the stability between the connecting piece and the card plate can be improved.

[0010] Optionally, a gap is provided between the two adhesive strips, with the adhesive strips located on both sides of the gap. By setting the gap, it is easier to disassemble the connecting piece later.

[0011] As can be seen from the above technical solution, the beneficial effects of this utility model are as follows: by setting an adhesive sheet to connect the connecting piece with the support plate next to the socket, and then using a card plate to provide support, and limiting the USB plug and wire harness by the relatively set sealing plate and rubber card block, the shaking of the USB slot and USB plug during vehicle movement can be reduced, and the connection effect of the USB socket and plug can be improved.

[0017] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0018] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0019] Please refer to the following: Figure 1-3 The diagram illustrates a structure to prevent USB plug loosening, comprising connecting pieces 1. Connecting pieces 1 are fixedly connected to the upper and lower sides of a socket via adhesive strips 2. A certain range of the upper and lower sides of the USB slot is exposed to facilitate the adhesion of the adhesive strips 2. Adaptive grooves 3 are provided on opposite sides of the two connecting pieces 1, contacting the plug. A retaining plate 4 is fixedly connected to one side of the connecting piece 1 near the adaptive groove 3. The two retaining plates 4 contact the upper and lower sides of the USB slot. Two sealing plates 5 are hinged to the end of the retaining plate 4 away from the connecting piece 1. Cable routing grooves 6 are provided on the sealing plates 5, facilitating the removal of the USB cable. Limiting grooves 7 are provided on the opposite sides of the two retaining plates 4. Rubber blocks 11 are fixedly connected to the side of the sealing plate 5 near the adaptive groove 3. The two opposing rubber blocks 11 press against each other, increasing friction with the USB cable harness and improving stability.

[0020] Two gaskets 10 are fixedly connected to the end of the card plate 4 away from the limiting groove 7. The gaskets 10 are made of rubber and have recesses on them that correspond to the limiting groove 7. By setting the gaskets 10, friction is increased on both sides of the USB plug, and energy release effect is also provided.

[0021] Among them, a U-shaped card 8 is snapped into the limiting groove 7, and a positioning rod 9 is threadedly connected to one side of the U-shaped card 8. The U-shaped card 8 contacts the card plate 4. By setting the U-shaped card 8 and the positioning rod 9, the connection between the card plate 4 and the USB plug can be kept tight.

[0022] Among them, a fixing strip 12 is fixedly connected to the side of the card plate 4 away from the rubber card block 11. One end of the fixing strip 12 is fixedly connected to the end of the connecting piece 1 away from the adhesive strip 2. By setting the fixing strip 12, the support effect between the connecting piece 1 and the card plate 4 can be improved.

[0023] A gap 13 is provided between the two adhesive strips 2, with the adhesive strips 2 located on both sides of the gap 13. By providing the gap 13, it can be easily disassembled when not in use.

[0024] Working principle: When it is necessary to connect the USB plug to the USB slot, the connecting piece 1 is connected to the upper and lower sides of the USB slot by the adhesive strip 2. Then, the USB plug is inserted into the slot, and the U-shaped card 8 and the positioning rod 9 are used to lock the limiting groove 7. The sealing plate 5 is rotated to close one end of the card plate 4. Then, the wire harness at the USB plug extends out and passes through the wire harness groove 6. At this time, the sealing plate 5 rotates to contact the card plate 4. The rubber blocks 11 on both sides squeeze each other to increase the friction, thereby making the connection between the USB plug and the slot stable.

[0025] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
