Description

Technical Field

[0001] This utility model relates to the field of audio adapter technology, specifically a noise-reducing and interference-preventing Type-C audio adapter. Background Technology

[0002] With the standardization of electronic device interfaces, the Type-C interface has been widely used in various smart terminal devices such as smartphones, laptops, and tablets due to its advantages such as high transmission rate, strong compatibility, and reversible plug-in. In order to meet the compatibility requirements of traditional 3.5mm audio devices and Type-C interface devices, Type-C audio adapters have become common accessories in the current consumer electronics field. Their core function is to realize signal conversion and stable transmission between the Type-C interface and the audio interface.

[0003] However, existing Type-C audio adapters still have significant technical shortcomings in practical use:

[0004] Most current Type-C audio adapters lack targeted electromagnetic shielding design, or the shielding materials used have limited electromagnetic shielding performance, failing to effectively block external electromagnetic radiation interference. Electromagnetic signals generated by the terminal device's own circuitry, as well as radiation signals from surrounding electronic devices such as routers and chargers, can easily intrude into the audio signal transmission path inside the adapter, causing problems such as noise, distortion, and decreased signal-to-noise ratio in the audio signal, seriously affecting the user's listening experience. This problem is even more prominent in scenarios with high sound quality requirements, such as professional audio monitoring and game voice calls.

[0005] Some existing adapters only provide simple protection for the Type-C interface, neglecting to protect the critical signal transmission connection cable and audio interface from interference. This allows interference signals to penetrate through unprotected areas, resulting in poor anti-interference performance. Therefore, it is necessary to design a noise-reducing and anti-interference Type-C audio adapter to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a noise-reducing and interference-resistant Type-C audio adapter to solve the problems mentioned in the background art.

[0008] The first protective mechanism includes a first shielding cover, which is slidably connected to the periphery of the connection interface. A plug rod is fixedly connected to the left side of the first shielding cover, and a connecting seat is inserted into the periphery of the plug rod. The connecting seat is fixedly connected to the periphery of the left end of the connection interface. A connecting block is fixedly connected to the left side of the first shielding cover, and the connecting block is inserted into the interior of the connecting seat. A fixing pin is threadedly connected inside the connecting block. A rubber shielding sleeve is slidably connected to the periphery of the left end of the connecting seat. A connecting wire is slidably connected to the inner side of the rubber shielding sleeve. An audio interface is fixedly connected to the left side of the connecting wire. A first limiting pin is threadedly connected inside the rubber shielding sleeve.

[0009] Preferably, the fixing pin passes through the inside of the connector, and the first shield is made of beryllium copper alloy, which facilitates the stability between the first shield, the connector block and the connector by means of the fixing pin.

[0010] Preferably, the connecting line is fixedly connected to the left side of the connecting interface, and the first limiting pin passes through the inside of the connecting seat, so as to ensure the stability between the rubber shielding sleeve and the connecting seat through the first limiting pin.

The two sets of rubber shielding sleeves are interlocked, which facilitates the protection and anti-interference effect of the outer periphery of the connecting line through the rubber shielding sleeves.

[0012] Preferably, the second protective mechanism includes a mounting base, which is fixedly connected to the outer periphery of the right end of the audio interface. A second shielding cover is threadedly connected inside the mounting base, and the second shielding cover is slidably connected to the outer periphery of the audio interface. The mounting base is disposed on the left side of the rubber shielding sleeve, and a second limiting pin is threadedly connected inside the mounting base, the second limiting pin penetrating inside the rubber shielding sleeve.

[0013] Preferably, the right side of the mounting base is in contact with the left side of the two sets of rubber shielding sleeves, and the second shielding cover is made of beryllium copper alloy material, which facilitates the protection and anti-interference effect of the audio interface periphery through the second shielding cover.

[0014] Preferably, there are two sets of the second limiting pins, which are symmetrically distributed on the upper and lower sides of the mounting base and pass through the interior of the two sets of rubber shielding sleeves, so as to further ensure the stability between the rubber shielding sleeve and the mounting base through the second limiting pins.

The first shielding cover is made of beryllium copper alloy, which possesses excellent electromagnetic shielding properties, effectively blocking external electromagnetic radiation from interfering with audio signals. Then, the fixing pin is threaded into the connector and connecting block to ensure the stability of the first shielding cover and facilitate installation and disassembly. After the first shielding cover is fixed, two sets of rubber shielding sleeves are slidably connected to the left outer edge of the connector and the outer edge of the connecting cable, interlocking to protect the outer edge of the connecting cable and prevent interference without affecting the bending and use of the connecting cable. The combination of sliding and threaded connections improves the ease of installation and disassembly.

[0029] This utility model provides the following technical solution:

[0030] Example 1

[0031] Please see Figure 1-7 This utility model provides a technical solution: a noise reduction and anti-interference Type-C audio adapter, including a connection interface 1, a first protective mechanism 2 is provided around the connection interface 1, and a second protective mechanism 3 is provided around the left end of the first protective mechanism 2;

[0032] The first protective mechanism 2 includes a first shield 21, which is slidably connected to the periphery of the connection interface 1. A plug rod 25 is fixedly connected to the left side of the first shield 21. A connector 27 is inserted into the periphery of the plug rod 25. The connector 27 is fixedly connected to the periphery of the left end of the connection interface 1. A connecting block 26 is fixedly connected to the left side of the first shield 21. The connecting block 26 is inserted into the interior of the connector 27. A fixing pin 28 is threadedly connected inside the connecting block 26. A rubber shield 24 is slidably connected to the periphery of the left end of the connector 27. A connecting wire 22 is slidably connected to the inside of the rubber shield 24. An audio interface 23 is fixedly connected to the left side of the connecting wire 22. A first limit pin 29 is threadedly connected inside the rubber shield 24.

[0033] The fixing pin 28 passes through the inside of the connector 27. The first shield 21 is made of beryllium copper alloy, which makes it easy to ensure the stability between the first shield 21, the connector 26 and the connector 27 through the fixing pin 28.

[0034] The connecting wire 22 is fixedly connected to the left side of the connecting interface 1, and the first limiting pin 29 passes through the inside of the connecting seat 27, so as to ensure the stability between the rubber shielding sleeve 24 and the connecting seat 27 through the first limiting pin 29.

[0035] Two sets of rubber shielding sleeves 24 and first limiting pins 29 are provided, and are respectively slidably connected to the outer periphery of the left end of the connecting seat 27 and the outer periphery of the connecting line 22. The two sets of rubber shielding sleeves 24 are interlocked, which facilitates the protection and anti-interference effect of the outer periphery of the connecting line 22 through the rubber shielding sleeves 24.

[0036] Example 2

[0037] Please see Figure 1-7 Furthermore, based on Embodiment 1, the second protective mechanism 3 includes a mounting base 31, which is fixedly connected to the outer periphery of the right end of the audio interface 23. A second shielding cover 32 is threadedly connected inside the mounting base 31 and slidably connected to the outer periphery of the audio interface 23. The mounting base 31 is located on the left side of the rubber shielding sleeve 24, and a second limiting pin 33 is threadedly connected inside the mounting base 31 and penetrates the interior of the rubber shielding sleeve 24.

[0038] The right side of the mounting base 31 is in contact with the left side of the two sets of rubber shielding sleeves 24. The second shielding cover 32 is made of beryllium copper alloy, which facilitates the protection and anti-interference effect of the audio interface 23.

[0039] Two sets of second limiting pins 33 are provided and symmetrically distributed on the upper and lower sides of the mounting base 31, and respectively penetrate into the interior of the two sets of rubber shielding sleeves 24, so as to further ensure the stability between the rubber shielding sleeves 24 and the mounting base 31 through the second limiting pins 33.

[0040] In actual operation, when this device is used, when the Type-C audio adapter is in use, first insert the plug 25 and the connecting block 26 into the connector 27, and slide the first shield 21 to the outside of the connector interface 1, which can protect and prevent interference to the outside of the connector interface 1. Then, thread the fixing pin 28 into the connector 27 and the connecting block 26 to ensure the stability of the first shield 21 and facilitate installation and disassembly. After the first shield 21 is fixed, thread the second shield 32 into the mounting base 31 and slide it to the outside of the audio interface 23, which can protect and prevent interference to the outside of the audio interface 23.

The left side of the two sets of rubber shielding sleeves 24 is in contact with the right side of the mounting seat 31, which can protect and prevent interference to the outer periphery of the connecting line 22 without affecting the bending and use of the connecting line 22. At this point, the first limiting pin 29 can be threaded into the rubber shielding sleeve 24 and the connecting seat 27, and the second limiting pin 33 can be threaded into the rubber shielding sleeve 24 and the mounting seat 31, which can further fix the two sides of the rubber shielding sleeve 24. The first shielding cover 21 and the second shielding cover 32 are made of beryllium copper alloy. Beryllium copper alloy has excellent electromagnetic shielding performance, which can effectively block the interference of external electromagnetic radiation to audio signals. It can attenuate the interference signal layer by layer, greatly reduce the noise in the signal transmission process, and improve the clarity and stability of audio output.

[0042] Each component adopts a combination of sliding and threaded connections to improve the ease of installation and disassembly, while not affecting the normal use of connection interface 1 and audio interface 23;

[0043] In this case, connection interface 1 is the Type-C interface.
