Description

Technical Field

[0001] The utility model relates to the technical field of audio isolators, and particularly relates to an audio isolator with an improved structure. Background Technique

[0002] An audio isolator is a transformer working in the audio range. By converting the current of the input signal into a magnetic field signal and then using the magnetic field signal to reconvert into the output current signal, the purpose of isolating the input and output signals is achieved, effectively isolating the noise and interference in different paths and improving the purity and clarity of the audio signal.

[0003] Chinese Patent (Publication No. CN211350340U) discloses an audio isolator. The two ends of the main body of the audio isolator are respectively connected to a first connector and a second connector. The interface forms of the first connector and the second connector are different, which can meet the simultaneous connection of two different wiring components. By setting a clamping device, the connection between the first connector and the first wiring can be strengthened, playing a fixing role and preventing the first wiring from falling off due to shaking.

[0004] However, the second connector of the audio isolator connected to the device does not have a protection component, so that the metal guide posts are exposed outside, which will be affected by the accumulation of water vapor around, so that water accumulates on the contact surface connected by the metal guide posts, resulting in unstable transmission signals and noise generation, and reducing the clarity of the sound quality. Content of the Utility Model

[0005] In view of the above problems, an audio isolator with an improved structure is provided. By setting a moisture-proof mechanism, the water absorption silica gel balls can adsorb water, avoiding the accumulation of water on the metal contact surface of the guide post, reducing the influence on the signal transmission stability, and solving the problem that water easily accumulates on the metal contact surface of the guide post, resulting in unstable transmission signals, noise generation, and reducing the clarity of the sound quality.

[0006] In order to solve the problems of the prior art, the utility model provides the following technical solutions:

[0007] An audio isolator with an improved structure includes a main body. Two first connectors are arranged at one end of the main body, and a second connector corresponding to the two first connectors is arranged at the other end of the main body. The first connector includes a guide post and a first raised ring, and the second connector includes a wiring post and a second raised ring. A moisture-proof mechanism for preventing water from accumulating on the surface of the guide post is provided on the first connector. The moisture-proof mechanism includes a sealing sleeve ring arranged around the socket of the first connector and a water absorption sleeve ring arranged at the opening of the sealing sleeve ring.

[0008] Preferably, the water-absorbing collar includes an annular housing and water-absorbing silica gel balls. The annular housing is disposed at the socket of the first connector. There are several water-absorbing silica gel balls, which are filled in the cavity of the annular housing. Several water-absorbing holes are formed in the annular housing. Symmetrically arranged on the outside of the annular housing are support columns extending towards the main body. The extending ends of the support columns are provided with mounting plates, and the mounting plates are fixedly arranged on the main body.

[0009] Preferably, a through hole is radially formed in the annular housing along its axis, and a piston is inserted into the through hole.

[0010] Preferably, the sealing collar includes an annular sealing isolation pad. The annular sealing isolation pad is arranged on the main body. Limiting grooves adapted to each support column are formed on the outside of the annular sealing isolation pad. The annular sealing isolation pad is clamped between the two support columns through the two limiting grooves, and the annular sealing isolation pad is located between the annular housing and the main body.

[0011] Preferably, a keyway is formed in the first raised ring.

[0012] Preferably, a USB interface is provided on the main body. The USB interface is located between two groups of second connectors. A jack is provided on the main body, and the jack is located between two groups of first connectors.

[0013] Preferably, protective kits are symmetrically sleeved on the main body. Anti-collision ear plates are symmetrically and fixedly arranged on the main body on both sides of the first connector and the second connector.

[0014] The beneficial effects of the present utility model compared with the prior art are as follows:

[0015] By providing a moisture-proof mechanism, the present utility model achieves the effect of facilitating water absorption. The water-absorbing silica gel balls adsorb moisture through the water-absorbing holes and the annular grooves, avoiding the accumulation of moisture on the metal contact surfaces of the guide posts, reducing the influence on the signal transmission stability, and can eliminate the factors generating noise before the noise is generated. When the water-absorbing silica gel balls adsorb a large amount of moisture, the piston needs to be opened in time to replace the water-absorbing silica gel balls to ensure the moisture-proof function of the moisture-proof mechanism. By using the annular sealing isolation pad, the gap after the connection between the first connector and the connecting wire can be eliminated, and a certain water-blocking effect is achieved, further playing a moisture-proof role and improving the protection effect of the audio isolator.

Detailed implementation mode

[0022] To further understand the features, technical means, and specific purposes and functions achieved by the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation modes.

[0023] See Figures 1 - 5 As shown, an audio isolator with an improved structure includes a main body 100. Two first connectors 200 are provided at one end of the main body 100, and a second connector 400 corresponding to the two first connectors 200 is provided at the other end of the main body 100. The first connector 200 includes a guide post 201 and a first raised ring 204, and the second connector 400 includes a terminal 401 and a second raised ring 402. A moisture-proof mechanism 300 for preventing moisture from accumulating on the surface of the guide post 201 is provided on the first connector 200. The moisture-proof mechanism 300 includes a sealing sleeve ring disposed around the socket of the first connector 200 and a water absorption sleeve ring disposed at the opening of the sealing sleeve ring.

[0024] The first raised ring 204 is provided at one end of the main body 100, the guide post 201 is fixedly provided inside the first raised ring 204, the second raised ring 402 is provided at the other end of the main body 100, and the terminal 401 is fixedly provided inside the second raised ring 402. When using the audio isolator, according to the different interface forms of the first connector 200 and the second connector 400, different devices are connected, and the water absorption component is installed on the main body 100 at one end of the first connector 200 by using the installation component. The water vapor is adsorbed by the water absorption component to prevent the accumulation of water vapor and avoid the accumulation of moisture on the metal contact surface of the guide post 201 inside the first connector 200.

[0025] By setting the first connector 200 and the second connector 400 with different interface forms, the connection requirements of different interface devices can be met, the versatility of the audio isolator is improved, the usage range of the audio isolator is expanded, the flexibility and practicality of the audio isolator are enhanced. At the same time, by setting two groups of the first connector 200 and the second connector 400, it is convenient to perform multi-group audio transmission simultaneously, ensuring the transmission efficiency of the audio signal. By setting the moisture-proof mechanism 300, moisture accumulation on the metal contact surface of the guide post 201 can be avoided, thereby preventing noise generation caused by unstable transmission signals.

[0026] See Figures 1 - 5 As shown, the water-absorbing sleeve ring includes an annular housing 301 and water-absorbing silica gel balls 308. The annular housing 301 is arranged at the socket of the first connector 200. There are several water-absorbing silica gel balls 308 and they are filled in the cavity of the annular housing 301. Several water-absorbing holes 302 are opened on the annular housing 301. Symmetrically arranged on the outside of the annular housing 301 are support columns 304 extending towards the main body 100. An installation plate 305 is provided at the extended end of the support column 304, and the installation plate 305 is fixedly arranged on the main body 100.

[0027] The annular housing 301 is installed on the main body 100 by bolts. The water-absorbing silica gel balls 308 adsorb moisture through the water-absorbing holes 302 and the annular grooves 307, avoiding moisture accumulation on the metal contact surface of the guide post 201 and reducing the impact on the signal transmission stability, and can eliminate the factors causing noise before the noise is generated. It solves the problem of how to avoid water vapor accumulation on the surface of the guide post 201.

[0028] See Figures 2 - 4 As shown, a through hole is radially opened along the axis of the annular housing 301, and a piston 303 is inserted into the through hole.

[0029] When the water-absorbing silica gel balls 308 adsorb a large amount of moisture, the piston 303 needs to be opened in time to replace the water-absorbing silica gel balls 308 to ensure the moisture-proof function of the moisture-proof mechanism 300. It solves the problem of how to facilitate the replacement of the water-absorbing silica gel balls 308.

[0030] See Figures 3 - 5 As shown, the sealing sleeve ring includes an annular sealing isolation pad 306. The annular sealing isolation pad 306 is arranged on the main body 100. A limiting groove 309 adapted to each support column 304 is opened on the outside of the annular sealing isolation pad 306. The annular sealing isolation pad 306 is clamped between two support columns 304 through two limiting grooves 309, and the annular sealing isolation pad 306 is located between the annular housing 301 and the main body 100.

[0031] The annular sealing spacer 306 is provided to eliminate the gap after the connection between the first connector 200 and the connecting wire, achieve a certain water-blocking effect, further play a moisture-proof role, and improve the protection effect of the audio isolator.

[0032] See Figure 1 As shown, a keyway 202 is provided on the first convex ring 204.

[0033] The keyway 202 is provided to prevent the connecting wire from rotating after connection, enhance the connection stability, ensure the transmission quality of the audio signal, reduce signal loss, make the audio signal purer during transmission, and the sound quality clearer.

[0034] See Figures 1 - 2 As shown, a USB interface 103 is provided on the main body 100. The USB interface 103 is located between two groups of second connectors 400, and a jack 203 is provided on the main body 100. The jack 203 is located between two groups of first connectors 200.

[0035] By providing the USB interface 103 and the jack 203, it is convenient for users to connect other digital audio devices through the USB interface 103, realize the digital transmission and processing of audio signals, and improve the versatility of the audio isolator.

[0036] See Figures 1 - 2 As shown, a protective kit 101 is symmetrically sleeved on the main body 100, and anti-collision ear plates 102 are symmetrically fixed on the main body 100 on both sides of the first connector 200 and the second connector 400.

[0037] By providing the protective kit 101 and the anti-collision ear plates 102, it plays a protective role for the audio isolator.
