USB connection structure of audio acquisition card

Abstract

The utility model discloses a universal serial bus (USB) connection structure of an audio acquisition card, which comprises a USB connection pipe, an acquisition card body is arranged at one end of the USB connection pipe, and a clamping port is arranged on the inner side of the USB connection pipe. Through cooperation of the sliding groove, the sliding plate, the push button, the USB adapter tube, the clamping block and the acquisition card body, the sliding groove can provide a fixed moving direction for the sliding plate, and when the push button is pushed, the push button can push the sliding plate to move towards the USB adapter tube, so that the sliding plate can drive the clamping block to extend outwards and enter the clamping port. When the acquisition card body encounters external accidental pulling force, the clamping piece is blocked by the clamping block and is inserted into the clamping port in the USB receiving port, so that the clamping piece cannot be separated from the clamping port, the locking degree between the USB adapter and the USB receiving port can be enhanced when the USB adapter does not need to be pulled out, and the USB adapter is prevented from being pulled out. Therefore, the problem that the audio acquisition card and the USB connecting port fall off from the computer and fall on the ground when the audio acquisition card is pulled accidentally is solved.

Description

Technical Field

[0001] The utility model relates to the technical field of USB interfaces, in particular to a USB connection structure of an audio acquisition card. Background Art

[0002] An audio capture card is a piece of hardware that can capture both audio and video signals at the same time. Different from the third-generation PCI capture card, there is no need to worry about excessive CPU consumption or asynchrony between audio and video signals. The capture principle is that the audio capture card samples and quantizes the captured signal image, converts it into a digital image, and inputs and stores it into the frame memory.

[0003] The data transceiver of the audio capture card adopts the USB3.0 form factor standard. Although there is also a Type-C form factor standard, the audio capture card using the Type-C form factor standard is suitable for mobile phones. An adapter is required when connecting to a computer. Since audio capture cards are mostly used for external computers, conventional capture cards mainly use the USB3.0 standard.

[0004] At present, the audio capture card is small in size, and mainly extends a data cable with a USB connection port. It is still easy to have some problems when it is plugged into a computer or connected to a computer using an adapter, because this device with a small size and relatively sensitive to the outside world cannot be impacted, especially when it falls. In addition to the conventional friction force, the connection between the conventional USB connection port and the receiving port mainly relies on four clamping pieces distributed on the upper and lower sides of the USB receiving port. Since this clamping piece forms an inwardly concave shape during processing, after the USB connection port is inserted, this clamping piece can be inserted into the four card interfaces reserved for the USB connection port, thereby realizing the card connection function. However, one end of the USB connection port will still fall off when subjected to an outward pull-out force. Therefore, when inserted into the computer, if it is accidentally pulled, it is very likely that the audio capture card and the USB connection port will fall off from the computer and fall to the ground, thereby causing damage to the microphone or other electronic components inside the audio capture card. In order to solve this technical problem, the utility model proposes a USB connection structure of an audio capture card. Utility Model Content

[0005] The main purpose of the utility model is to provide a USB connection structure of an audio capture card, which can effectively solve the problems mentioned in the background technology.

[0007] A USB connection structure of an audio capture card comprises a USB pipe, one end of which is mounted with a capture card body, a card interface is arranged on the inner side of the USB pipe, a slide groove is provided on the inner side of the USB pipe and the capture card body, a slide plate is slidably connected to the inner wall of the slide groove, a push button is arranged on the outside of the capture card body, and a card connection block is arranged on the inside of the USB pipe.

[0008] Preferably, a snap-in groove is provided on the inner side of the USB tube, the outer surface of the snap-in block is slidably connected to the inner wall of the snap-in groove, the interior of the snap-in groove is communicated with the interior of the slide groove, and an extrusion block is provided on the outer surface of the slide plate, and the outer surface of the extrusion block is in contact with the outer surface of the snap-in block.

[0009] Preferably, a slide rail is fixedly connected to the outer surface of the clamping block, and slideways are provided on the outer surfaces of both sides of the extrusion block, and the outer surfaces of the slideways are slidably connected to the outer surfaces of the slide rails.

[0010] Preferably, a groove is provided on the outer surface of the acquisition card body, the outer surface of the groove is slidably connected to the outer surface of the push button, and the bottom surface of the push button is fixedly connected to the outer surface of the slide plate.

[0011] Preferably, the inner side of the USB tube is rotatably connected to a dust cover, the inner wall of the dust cover is slidably connected to a control rod, the outer surface of the control rod is rotatably connected to the inner wall of the USB tube, the outer surface of the control rod is contact-connected with a return spring, and the other end of the return spring is fixedly connected to the inner surface of the USB tube.

[0012] Preferably, the other end of the control rod is pluggably connected with a disassembly cover, and the outer surface of the disassembly cover is rotatably connected to the inner wall of the USB connecting pipe.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] When the USB port is not pulled out, the card holder can be easily moved out of the computer and the card interface can be easily moved.

[0015] In the utility model, through the cooperation between the return spring, the control rod, the dust cover and the USB tube, the return spring can always push the control rod, and the control rod itself cannot rotate freely on the inner wall of the dust cover, so that the control rod can drive the dust cover to block the inside of the USB tube, so that when the device is idle, it can reduce the situation that external debris enters the inside of the USB tube. When it is inserted into the USB receiving port, the thrust of the receiving plate inside it is greater than the thrust of the return spring, so that the dust cover can be pushed to rotate and adhere to the inner top wall of the USB tube. When the device is unplugged, it is constrained by the thrust of the return spring and the dust cover can block the inside of the USB tube, so that the device is not easily blocked by external dust or debris.

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0026] like Figure 1-8 As shown, a USB connection structure of an audio capture card comprises a USB pipe 1, a capture card body 2 is installed at one end of the USB pipe 1, a card interface 3 is arranged on the inner side of the USB pipe 1, a slide groove 4 is provided on the inner side of the USB pipe 1 and the capture card body 2, a slide plate 5 is slidably connected to the inner wall of the slide groove 4, a push button 6 is arranged on the outside of the capture card body 2, and a card connection block 7 is arranged inside the USB pipe 1, the slide groove 4 can provide a fixed moving direction for the slide plate 5, when the push button 6 is pushed, the push button 6 can push the slide plate 5 to move in the direction of the USB pipe 1, so that the slide plate 5 can drive the card connection block 7 to extend outward and enter the card In the interface 3, when the acquisition card body 2 encounters an unexpected suction force from the outside, the clamping piece of the card interface 3 inserted into the USB receiving port blocked by the clamping block 7 cannot be detached from the card interface 3, making it difficult for the USB tube 1 to be pulled out from the USB receiving port, which can play a certain insurance role. When it needs to be pulled out, it is only necessary to push the push button 6 back to its original position to reset the clamping block 7. When the USB tube 1 does not need to be pulled out, the locking degree between the USB tube 1 and the USB receiving port can be enhanced, thereby solving the problem that the audio acquisition card and the USB connection port may fall off the computer and fall to the ground due to accidental pulling.

[0027] A snap-in groove 8 is provided on the inner side of the USB pipe 1, and the outer surface of the snap-in block 7 is slidably connected to the inner wall of the snap-in groove 8. The interior of the snap-in groove 8 is communicated with the interior of the slide groove 4. An extrusion block 9 is provided on the outer surface of the slide plate 5. The outer surface of the extrusion block 9 is in contact with the outer surface of the snap-in block 7. The snap-in groove 8 can provide a direction for the movement of the snap-in block 7. When the slide plate 5 moves toward the direction of the USB pipe 1, it can push the extrusion block 9, so that the extrusion block 9 can squeeze and push the snap-in block 7 to extend outward, thereby achieving a snap-in effect.

[0028] The outer surface of the clamping block 7 is fixedly connected with a slide rail 10, and the outer surfaces of both sides of the extrusion block 9 are provided with slideways 11. The outer surface of the slideway 11 is slidably connected with the outer surface of the slide rail 10. The slide rail 10 and the slideway 11 enable the clamping block 7 to not only be slidably connected with the extrusion block 9, but also be clamped with each other, so that when the extrusion block 9 returns to its original position, the clamping block 7 is also driven to return to its original position.

[0029] A groove 12 is provided on the outer surface of the acquisition card body 2, and the outer surface of the groove 12 is slidably connected to the outer surface of the push button 6, and the bottom surface of the push button 6 is fixedly connected to the outer surface of the slide plate 5. The push button 6 can move in a fixed direction given by the groove 12, and the surface of the push button 6 is provided with a protrusion, which can increase the friction between the push button 6 and the finger, so that the slide plate 5 can be driven to move more conveniently by pushing the push button 6.

[0030] The inner side of the USB tube 1 is rotatably connected with a dust cover 13, and the inner wall of the dust cover 13 is slidably connected with a control rod 14. The outer surface of the control rod 14 is rotatably connected to the inner wall of the USB tube 1. The outer surface of the control rod 14 is in contact with a return spring 15, and the other end of the return spring 15 is fixedly connected to the inner surface of the USB tube 1. The return spring 15 can always push the control rod 14, and the control rod 14 itself cannot rotate freely on the inner wall of the dust cover 13, so that the control rod 14 can drive the dust cover 13 to block the inside of the USB tube 1, so that when the device is idle, it can reduce the situation that external debris enters the inside of the USB tube 1. When inserted into the USB receiving port, the thrust of the receiving plate inside it is greater than the thrust of the return spring 15, so that the dust cover 13 can be pushed to rotate and adhere to the inner top wall of the USB tube 1. When the device is unplugged, it is subject to the thrust of the return spring 15, and the dust cover 13 can block the inside of the USB tube 1, so that the device is not easily blocked by external dust or debris.

[0031] The other end of the control rod 14 is connected to a disassembly cover 16 by plugging and unplugging. The outer surface of the disassembly cover 16 is rotatably connected to the inner wall of the USB adapter 1. When the control rod 14 rotates, it can drive the disassembly cover 16 to rotate, and the disassembly cover 16 can prevent the control rod 14 from falling off from the inner wall of the USB adapter 1.
