Description

Technical Field

[0001] The invention relates to the technical field of USB connectors, in particular to a waterproof precision USB connector. Background Art

[0002] USB connector generally refers to USB interface, which is a serial bus standard and a technical specification of input and output interface. It is widely used in information communication products such as personal computers and mobile devices.

[0003] Commonly used USB connectors do not have a waterproof function. Regardless of whether they are used or not, if they come into contact with water, the internal circuit will short-circuit, causing the device to fail and be scrapped, greatly reducing its service life and causing unexpected damage.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a waterproof precision USB connector is proposed. Summary of the invention

[0005] The object of the present invention is to provide a waterproof precision USB connector to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a waterproof precision USB connector, comprising a bottom shell and a waterproof component, wherein the waterproof components are symmetrically arranged on both sides of the bottom shell, and the waterproof component comprises a slide groove, a slide rail, a slide plate, a baffle, a connecting rod, a slider and a sleeve shell, the bottom shell is symmetrically provided with slide grooves on both sides, and a slide rail is arranged on one side of the slide groove, a slide plate is slidably connected in the slide groove, and a baffle is rotatably connected to one side of the slide plate through an elastic rotating shaft, a connecting rod is connected to the other side of the slide plate, a slider is snap-connected in the slide rail, and a sleeve shell is sleeved on the outer side of the bottom shell.

[0007] Furthermore, the slide plate is connected to the bottom shell by a sliding groove, and the slider is slidably connected to the bottom shell by a sliding rail, and the cover shell is connected to the slide plate by the sliding rail, and the cover shell completely covers the sliding rail.

[0008] Furthermore, a mounting groove is provided in the middle of one side of the bottom shell, and an interface is connected in the mounting groove. An air cavity is symmetrically opened on the other side of the bottom shell, and a vent is provided on one side of the air cavity.

[0009] Furthermore, an air plate is snap-connected in the air cavity, and a pressure gas spring is connected to one side of the air plate, and the other side of the air plate is connected to a connecting rod, and the air plate is elastically connected to the air cavity through the pressure gas spring.

[0010] Furthermore, an airway is provided on one side of the vent, and a clamping slot is opened on one side of the airway, a clamping spring is connected in the clamping slot, and a clamping rail is provided on the other side of the clamping slot.

[0011] Furthermore, a card plate is connected to one side of the retaining spring, and a card block is connected to one side of the retaining plate. The retaining plate is concave in shape, and the retaining plate is elastically connected to the retaining groove through the retaining spring. The card plate airway is slidably connected, and the card block is slidably connected to the retaining rail.

[0012] Furthermore, a ventilation groove is arranged on one side of the card slot, and air holes are arranged between the ventilation groove and the mounting groove, and the air holes are distributed in an inclined array with respect to the ventilation groove.

[0013] Furthermore, a joint is snap-connected in the interface, and fixing grooves are symmetrically provided on both sides of the joint, and limiting grooves are symmetrically provided on both sides of the fixing groove. The joint is snap-connected and slidably connected with the bottom shell through the interface.

[0014] Furthermore, a plug-in spring is symmetrically connected in the fixing groove, and a fixing card is connected to one side of the plug-in spring, and limit cards are symmetrically connected to both sides of the fixing card.

[0015] Furthermore, the fixing card is elastically connected to the fixing slot via a plug-in spring, and the fixing card is snap-connected with the card board, the fixing card is snap-connected and slidably connected to the joint via the fixing slot, and the limiting card is snap-connected and slidably connected to the joint via the limiting slot.

[0016] The present invention provides a waterproof precision USB connector, which has the following beneficial effects: when not in use, the interface can be closed to be waterproof and dustproof, and when in use, dust can be removed from the interface simultaneously during the process of opening the interface, and during use, the connector can be fixed to avoid pulling the data line due to misoperation and pulling the connector out of the interface, resulting in connection interruption.

[0017] 1. When the present invention is not in use, the baffle can block and close the interface, thereby achieving waterproof and dustproof. When in use, the sleeve shell only needs to be slid on the outside of the bottom shell, so that the sleeve shell can drive the slider to slide in the slide rail, and then drive the slide plate to slide in the slide groove, so that the slide plate pulls the baffle into the slide groove to release the closure of the interface, so that the connector can be inserted for use. After the connector is pulled out, as the slide plate automatically returns to its original position, the baffle can also rotate under the action of the elastic shaft to close the interface again to prevent dust and water vapor from entering. In summary, when in use, the interface can be automatically blocked and closed, thereby achieving waterproof and dustproof.

[0018] 2. When the slide plate of the present invention moves, the slide plate can drive the air plate to move in the air cavity through the connecting rod and compress the air pressure spring. When the air plate moves, the air in the air cavity can be pressed out and squeezed into the airway from the vent, so that the air presses the card plate to slide out of the airway and compresses the retaining spring. When the card plate no longer blocks the ventilation groove, the air can enter the ventilation groove from the card groove and blow into the installation groove through the air hole to blow out the dust that may exist in the interface. After use, the air pressure spring can drive the air plate to rebound, so as to replenish the gas in the air cavity from the interface through the air hole, ventilation groove, airway and ventilation port. While the air plate rebounds, the slide plate can be driven to move back in the slide groove through the connecting rod, so as to push the baffle out of the slide groove. In summary, during use, the interface can be dusted, and after use, the baffle can be driven to reset.

[0019] 3. In the present invention, after the card slides out of the airway, as the baffle moves, when the baffle contacts the block, the baffle can be pushed by the block to rotate on the slide plate. When the baffle passes the block, the baffle rotates, and the card can be restricted by the block to prevent the card from rebounding under the action of the clamping spring, resulting in the inability to fix the interface. When in use, the connector is inserted into the interface. During the insertion process, the fixed card can be pressed by the block to move in the fixed groove and compress the plug-in spring. The limit card can follow the fixed card to move in the limit groove, thereby restricting the fixed card to prevent the fixed card from deflecting in the mobile high-rise residential building. When the connector is fully inserted into the interface, the fixed card rebounds under the action of the plug-in spring and engages with the card, so that the card restricts the connector through the fixed card, avoiding the problem of the card being unable to be fixed during use. In the process, the data line may be pulled out of the interface due to misoperation, resulting in an interruption of the connection. After use, the fixing card is pressed to move in the fixing slot, so that the restriction of the fixing card by the card plate can be contacted, so that the connector can be pulled out. After the connector is pulled out, the baffle is moved to rotate on the slide plate to release the restriction of the card block on the baffle plate, and the card plate is fixed at the same time. The air plate can drive the slide plate back to its position through the connecting rod under the action of the compressed air spring, and replenish air in the air cavity. After the air replenishment is completed, the card plate is released, and the card plate can rebound into the airway under the action of the retaining spring, and the baffle can also rebound under the action of the elastic rotating shaft to close and cover the interface. In summary, the connector can be fixed during use to avoid misoperation of pulling the data line and pulling the connector out of the interface, resulting in an interruption of the connection.

[0028] See also Figures 1 to 5The slide plate 203 is connected to the bottom shell 1 by the slide groove 201, and the slider 206 is slidably connected to the bottom shell 1 by the slide rail 202. The cover shell 207 is connected to the slide plate 203 by the slider 206, and the cover shell 207 completely blocks the slide rail 202.

[0029] The specific operation is as follows. When not in use, the baffle 204 can block and close the interface 4 to prevent water and dust. When in use, it is only necessary to slide the sleeve shell 207 on the outside of the bottom shell 1, so that the sleeve shell 207 can drive the slider 206 to slide in the slide rail 202, and then drive the slide plate 203 to slide in the slide groove 201, so that the slide plate 203 pulls the baffle 204 into the slide groove 201, and releases the closure of the interface 4, so that the connector 17 can be inserted for use. After the connector 17 is pulled out, as the slide plate 203 automatically returns to its original position, the baffle 204 can also rotate under the action of the elastic shaft to close the interface 4 again to prevent dust and water vapor from entering. In summary, when in use, the interface 4 can be automatically blocked and closed to prevent water and dust. When the slide plate 203 moves, the slide plate 203 can drive the air plate 7 to move in the air cavity 5 through the connecting rod 205, and When the compressed air spring 8 is compressed and the air plate 7 moves, the air in the air cavity 5 can be pressed out and squeezed into the air passage 9 from the vent 6, so that the air presses the card plate 13 to slide out of the air passage 9 and compresses the retaining spring 11. When the card plate 13 no longer blocks the ventilation groove 15, the air can enter the ventilation groove 15 from the card slot 10 and blow into the mounting groove 3 through the air hole 16 to blow out the dust that may exist in the interface 4. After use, the compressed air spring 8 can drive the air plate 7 to rebound, thereby replenishing the gas in the air cavity 5 from the interface 4 through the air hole 16, the ventilation groove 15, the air passage 9 and the vent 6. While the air plate 7 rebounds, the sliding plate 203 can be driven to move back in the slide groove 201 through the connecting rod 205, thereby pushing the baffle 204 out of the slide groove 201. In summary, during use, the interface 4 can be dusted, and after use, the baffle 204 can be driven to reset.

[0030] See also Figures 2 to 6 , a connector 17 is snap-connected in the interface 4, and a fixing groove 18 is symmetrically provided on both sides of the connector 17, and a limiting groove 19 is symmetrically provided on both sides of the fixing groove 18, the connector 17 is snap-connected and slidably connected with the bottom shell 1 through the interface 4, a plug spring 20 is symmetrically connected in the fixing groove 18, and a fixing card 21 is connected to one side of the plug spring 20, and a limiting card 22 is symmetrically connected on both sides of the fixing card 21, the fixing card 21 is elastically connected to the fixing groove 18 through the plug spring 20, and the fixing card 21 is snap-connected and linked with the card board 13, the fixing card 21 is snap-connected and slidably connected with the connector 17 through the fixing groove 18, and the limiting card 22 is snap-connected and slidably connected with the connector 17 through the limiting groove 19;

[0031] The specific operation is as follows: after the card plate 13 slides out of the airway 9, as the baffle 204 moves, when the baffle 204 contacts the block 14, the baffle 204 can be pushed by the block 14 to rotate on the slide plate 203. When the baffle 204 passes the block 14, the baffle 204 rotates, and the card plate 13 can be restricted by the block 14 to prevent the card plate 13 from rebounding under the action of the clamping spring 11, resulting in the inability to fix the interface 4. When in use, the connector 17 is inserted into the interface 4, and the plug During the insertion process, the fixing card 21 can be pressed by the card block 14 to move in the fixing groove 18 and compress the plug spring 20, and the limit card 22 can follow the fixing card 21 to move in the limit groove 19, thereby limiting the fixing card 21 to prevent the fixing card 21 from deflecting when moving the high-rise residential building. When the connector 17 is fully inserted into the interface 4, the fixing card 21 rebounds under the action of the plug spring 20 and engages with the card plate 13, so that the card plate 13 can lock the connector 17 through the fixing card 21. The restriction is to avoid the connector 17 being pulled out of the interface 4 due to the data line being pulled by mistake during use, resulting in the interruption of the connection. After use, the fixing card 21 is pressed and moved in the fixing groove 18, so that the restriction of the fixing card 21 by the card plate 13 can be contacted, so that the connector 17 can be pulled out. After the connector 17 is pulled out, the baffle 204 is moved to make it rotate on the slide plate 203, and the restriction of the baffle 204 by the card block 14 is released. At the same time, the card plate 13 is fixed, and the air plate 7 can drive the slide plate 203 to return to its original position through the connecting rod 205 under the action of the compressed air spring 8, and replenish air in the air cavity 5. After the air replenishment is completed, the card plate 13 is released, and the card plate 13 can rebound into the airway 9 under the action of the retaining spring 11, and the baffle 204 can also rebound under the action of the elastic rotating shaft to close and cover the interface 4. In summary, during use, the connector 17 can be fixed to avoid the data line being pulled out of the interface 4 due to mistaken operation, resulting in the interruption of the connection.

[0032] In summary, for this waterproof precision USB connector, when not in use, the baffle 204 can block and seal the interface 4, thereby achieving waterproof and dustproof properties. When in use, it is only necessary to slide the sleeve 207 on the outside of the bottom shell 1, so that the sleeve 207 can drive the slider 206 to slide in the slide rail 202, and then drive the slide plate 203 to slide in the slide groove 201, so that the slide plate 203 pulls the baffle 204 into the slide groove 201, releases the closure of the interface 4, and thus allows the connector 17 to be inserted for use. When the slide plate 203 moves, the slide plate 203 can drive the air plate 7 to move in the air cavity 5 through the connecting rod 205, and compress the air spring 8. When the air plate 7 moves, the air in the air cavity 5 can be pressed out and squeezed into the air passage 9 from the vent 6. , so that the air presses the card plate 13 to slide out of the air duct 9 and compresses the retaining spring 11. When the card plate 13 no longer blocks the ventilation groove 15, the air can enter the ventilation groove 15 from the card slot 10 and blow into the installation groove 3 through the air hole 16 to blow out the dust that may exist in the interface 4. After the card plate 13 slides out of the air duct 9, as the baffle 204 moves, when the baffle 204 contacts the block 14, the baffle 204 can be pushed by the block 14 to rotate on the slide plate 203. When the baffle 204 passes the block 14, the baffle 204 rotates, and the card plate 13 can be restricted by the block 14 to prevent the card plate 13 from rebounding under the action of the retaining spring 11, resulting in the inability to fix the interface 4. When in use, the connector 17 is inserted into the interface 4. During the insertion process, The fixing card 21 can be pressed by the card block 14 to move in the fixing groove 18 and compress the plug spring 20, and the limit card 22 can follow the fixing card 21 to move in the limit groove 19, thereby limiting the fixing card 21 to prevent the fixing card 21 from being deflected when moving in a high-rise residential building. When the connector 17 is fully inserted into the interface 4, the fixing card 21 rebounds under the action of the plug spring 20 and engages with the card board 13, so that the card board 13 restricts the connector 17 through the fixing card 21, thereby preventing the connector 17 from being pulled out of the interface 4 due to misoperation during use, resulting in connection interruption. After use, the fixing card 21 is pressed to move in the fixing groove 18, so that the restriction of the card board 13 on the fixing card 21 can be contacted, so that the connector 17 can be inserted into the interface 4. 7 is pulled out. After the connector 17 is pulled out, the baffle 204 is moved to rotate on the slide plate 203 to release the restriction of the block 14 on the baffle 204. At the same time, the card plate 13 is fixed, and the compressed air spring 8 can drive the air plate 7 to rebound, so that the air cavity 5 is replenished with gas from the interface 4 through the air hole 16, the ventilation groove 15, the air channel 9 and the vent 6. When the air plate 7 rebounds, the slide plate 203 can be driven to move back in the slide groove 201 through the connecting rod 205, so that the baffle 204 is pushed out from the slide groove 201. After the air replenishment is completed, the card plate 13 is released, and the card plate 13 can rebound into the air channel 9 under the action of the retaining spring 11, and the baffle 204 can also rebound under the action of the elastic rotating shaft to close and block the interface 4 to prevent dust and water vapor from entering.
