[0015] 1. The present invention reduces the vibration of the connector body caused by vehicle bumps by providing a polyurethane buffer strip and a polyurethane buffer lining. At the same time, the adsorption block and the anti-slip block inside the device increase the tightness between the USB connector and the connector body, preventing the USB connector and the connector body from slipping due to vibration. Therefore, compared with the existing technology, the present invention takes two approaches: buffering vibration and strengthening the connection between the connector body and the USB connector, thereby avoiding slipping of the connection.

DETAILED DESCRIPTION

[0029] The present invention will now be described in further detail with reference to the accompanying drawings.

[0030] See also Figures 1 to 8 The utility model provides a technical solution: a vehicle-mounted USB connector with a shockproof function, comprising a connector body 1, a polyurethane buffer strip 2, a polyurethane buffer lining 8 and an anti-slip block 6. The polyurethane buffer strip 2 is bonded to the four corners of the outer wall of the connector body 1. A groove for plugging in a USB connector 3 is provided inside the connector body 1. An inner core 5 that contacts the USB internal pin 4 is fixed in the middle of the groove. An anti-slip block 6 is provided on the inner side wall of the groove to prevent the USB connector 3 from slipping. A fixing groove 7 for plugging in the anti-slip block 6 is provided on the side wall of the USB connector 3.

[0031] The inner wall of the groove body is fixed with a polyurethane buffer lining 8, and the outer shape of the polyurethane buffer lining 8 is a U-shaped structure design. The lower surface of the polyurethane buffer lining 8 contacts the outer wall surface of the USB connector. Considering that when the vehicle is off-road or passing through a bumpy road, the constant bumps and shaking may easily cause the data cable of the vehicle-mounted equipment to be separated from the vehicle-mounted USB connector, resulting in the vehicle-mounted equipment being unable to be used normally. The utility model reduces the vibration caused by the vehicle bump on the connector body 1 by setting a polyurethane buffer strip 2 and a polyurethane buffer lining 8. At the same time, the adsorption block 9 and the anti-slip block 6 inside the device increase the tightness between the USB connector and the connector body 1, preventing the vibration from causing the USB connector 3 and the connector body 1 to slip. Therefore, compared with the prior art, the utility model takes two aspects of buffering vibration and strengthening the connection between the connector body 1 and the USB connector 3 to avoid the connection from slipping. When the vehicle is underway When off-roading causes continuous bumps, when the impact force is transmitted to the connector body 1, it will be initially buffered by the polyurethane buffer strip 2. When the impact force is transmitted to the inside of the slot body, the connection between the USB connector 3 and the connector body 1 will be buffered again by the polyurethane buffer lining 8, thereby weakening the impact force and avoiding the situation where the USB connector 3 and the connector body 1 slip due to excessive impact force. At the same time, in order to make the USB connector more durable, metal connectors have appeared on the market. Since the metal connector is an iron alloy, it can be adsorbed by the magnetic strip 10 inside the adsorption block 9. At this time, auxiliary fixing force will be provided between the connector body 1 and the USB connector, and after the USB connector 3 is inserted into the slot body, the anti-slip block 6 will be inserted into the inside of the fixing slot 7, so it can provide fixing force. At this time, the USB connector 3 will be doubly fixed by the magnetic strip 10 and the anti-slip block 6, effectively reducing the possibility of the USB connector 3 slipping.

[0032] Among them, the front end of the connector body 1 is provided with a strip groove for installing the adsorption block 9, and a magnetic strip 10 for adsorbing the metal shell of the USB connector 3 is provided inside each adsorption block 9. Considering that the USB connector on the market is more durable, the grip of the USB connector is designed to be scratch-resistant and wear-resistant metal. After the USB connector is plugged into the groove of the connector body 1, the metal grip can be magnetically adsorbed by iron alloy so that the grip of the USB connector is adsorbed on the front end of the connector body.

[0033] Among them, the front end surface of the connector body 1 is also provided with an embedded groove for installing the position marker light bar 11. By setting the position marker light bar 11, the user can quickly know the usage position of the vehicle-mounted connector body 1 in poor lighting conditions, making it convenient for the user to dock the USB connector 3 of the vehicle-mounted device with the connector body 1, and increasing the decorativeness of the device. In the later stage, the position marker light bar 11 can use RGB light strips as needed to increase the aesthetics of the device and cater to the interior layout of the vehicle.

[0034] Among them, the inner side wall of the trough body is fixed with a sleeve block 12, and a reserved groove for the horizontal movement of the anti-slip block 6 is opened at the side end of the sleeve block 12. The upper and lower ends of the inner side of the anti-slip block 6 are provided with guide holes 14 that match the internal guide rod 13 of the sleeve block 12. A reset spring 15 is provided inside the sleeve block 12, and the reset spring 15 is in contact between the anti-slip block 6 and the sleeve block 12. The front end of the anti-slip block 6 is fixed with a paddle 16 for the user to move the anti-slip block 6, and the paddle 16 is movably connected to the give way groove 17 opened on the front end surface of the sleeve block 12. Taking into account the situation that the connector body 1 and the USB connector 3 are prone to slipping due to continuous bumps, the anti-slip block 6 will be used to plug into the fixing groove 7 to increase the stability between the connector body 1 and the USB connector 3. When connecting the device, the anti-slip block 6 is first retracted into the inside of the sleeve block 12 through the paddle 16 and then the USB connector 3 is plugged in. After the plugging is completed, the paddle 16 is released. At this time, the reset spring 15 resets and drives the anti-slip block 6 to push out and insert into the fixing groove 7 on the side wall of the USB connector 3 to complete the position locking.

[0035] Among them, the sleeve block 12 is fixedly connected to the slot body through a fixing bolt 18, and a damping grease 19 is provided between the guide hole 14 and the guide rod 13. The setting of the fixing bolt 18 plays a fixing role between the sleeve block 12 and the slot body, and considering the influence of the reset of the manual reset spring 15 of the anti-slip block 6, the impact force generated during the reset will cause the connection between the USB connector 3 and the connector body 1 to be driven by the damping grease 19. Therefore, when the reset spring 15 drives the anti-slip block 6 to reset, the physical property of the damping grease 19 can buffer the anti-slip block 6, so that the anti-slip block 6 will slow down the spring, reducing the impact caused by the anti-slip block 6 popping out.

[0036] Among them, the inner wall of the polyurethane buffer strip 2 is provided with an adhesive layer 20 for bonding to the outer surface of the connector body 1, and a release paper 21 is adhered to the surface of the adhesive layer 20. By setting the adhesive layer 20, the polyurethane buffer strip 2 and the outer surface of the connector body 1 are bonded.

[0037] Among them, a cavity for installing the shielding layer 22 is opened inside the wall of the connector body 1. Considering that the magnetic strip 10 used to adsorb the metal holding end of the USB connector 3 will affect data transmission, a shielding layer 22 is set inside the wall of the connector body 1 to reduce the impact of the magnetic force of the magnetic strip 10 on data transmission.

[0038] The present invention is not limited to the above-described embodiments. Any structural changes made under the guidance of the present invention should be understood by anyone. Any technical solution that is the same or similar to the present invention falls within the scope of protection of the present invention. The technology, shape, and structure not described in detail in the present invention are all known technologies.
