Abstract
Description
Technical Field
[0001] This utility model relates to the field of power amplifier technology, and in particular to a power amplifier with a connection wire anti-disconnection structure. Background Technology
[0002] Power amplifiers, or simply power amplifiers, constitute the largest family of audio equipment. Their primary function is to amplify the weak signals input from audio source equipment, generating a sufficiently large current to drive speakers for sound reproduction. Due to considerations of power, impedance, distortion, dynamics, as well as different usage ranges and control adjustment functions, different power amplifiers vary in their internal signal processing, circuit design, and manufacturing processes.
[0003] Currently, Chinese patent publication number CN221652567U discloses a power amplifier. Its technical solution includes a power amplifier body and ventilation openings. The power amplifier body has symmetrically arranged ventilation openings on its front and rear surfaces. Fixing brackets are symmetrically fixedly installed on the front and rear surfaces of the power amplifier body. Limiting grooves are symmetrically provided at the top and bottom of the inner walls of the two fixing brackets. Storage boxes are symmetrically fixedly installed on one side of the front and rear surfaces of the power amplifier body. Rewinding shafts are rotatably installed inside each of the two storage boxes. Elastic metal sheets are fixedly connected to the outer surfaces of each of the two rewinding shafts, and positioning tubes are fixedly connected to the ends of each of the two elastic metal sheets. This invention allows for adjustment of the size of the ventilation openings on the outer casing according to the power amplifier's usage scenario and internal heat generation, avoiding a shortened lifespan due to high temperatures, and thus has high applicability.
[0004] Currently, the power amplifiers in the above-mentioned solutions and existing technologies do not have a structure to limit the connection cable. When people walk by and accidentally pull on the power amplifier connection cable, it is easy to cause the connection cable plug and the power amplifier socket to become loose, resulting in poor contact. In severe cases, it may cause the connection cable plug to fall off the power amplifier socket. Sudden disconnection is more likely to damage the audio system connected to the power amplifier, causing economic losses. Therefore, we provide a power amplifier with a connection cable anti-detachment structure. Utility Model Content

[0016] (III) Beneficial Effects
[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0026] The technical solution in this application embodiment effectively solves the problem that the power amplifier in the above-mentioned solutions and the prior art does not have a structure to limit the connection cable. When people walk by and accidentally pull on the power amplifier connection cable, it is easy for the connection cable plug to become loose and the power amplifier socket to become poor contact. In severe cases, the connection cable plug may even become detached from the power amplifier socket. Sudden disconnection can easily damage the audio system connected to the power amplifier, causing economic losses. The overall idea is as follows:
[0027] like Figures 1 to 4 To address the problems existing in the prior art, this utility model provides a power amplifier with a connection line anti-detachment structure, including a power amplifier 1, a mounting plate 2 fixedly connected to one side of the power amplifier 1, multiple slots 11 provided on one side of the power amplifier 1, a fixing plate 5 fixedly connected to one side of the power amplifier 1 located in the slots 11, multiple limiting grooves 53 corresponding to the slots 11 being opened on the surface of the fixing plate 5, a connection line 4 provided on one side of the limiting grooves 53, a mounting block 41 fixedly connected to the outside of the connection line 4, a plug 42 corresponding to the slot 11 being provided on one side of the mounting block 41, a mounting frame 3 fixedly connected to the top middle position of the power amplifier 1, a cooling fan 31 mounted on the mounting frame 3, a filter assembly 32 provided at the upper end of the mounting frame 3, ear blocks 51 fixedly connected to both sides of the fixing plate 5, and a fixing assembly 54 for fixing the mounting block 41 being provided on one side and below the fixing plate 5.
[0028] Specifically, the filter assembly 32 includes a filter plate 33, a long groove 34, a magnetic block 35, and a magnetic plate 36. A long groove 34 is provided on the upper side of one side of the mounting frame 3. The filter plate 33 is inserted into the long groove 34. Magnetic plates 36 are fixedly connected to both sides of the filter plate 33. Magnetic blocks 35 corresponding to magnetic plates 36 are fixedly connected to the inner side of the long groove 34.
[0029] By adopting the above technical solution, the cooling fan 31 can dissipate heat for the power amplifier 1, and the filter plate 33 can cool the air entering the power amplifier 1. At the same time, by pulling the filter plate 33, the filter plate 33 can be pulled out from the long slot 34 for cleaning. At this time, the magnetic plate 36 and the magnetic block 35 are separated. Similarly, the cleaned filter plate 33 is inserted into the long slot 34. At the same time as insertion, the magnetic block 35 will attract the magnetic plate 36, which can fix the filter plate 33.
[0030] Specifically, the fixing component 54 includes a plug rod 55, a connecting plate 56, a restoring spring 57, a reinforcing rod 58, a limiting piece 59, and a spring 510. The plug rod 55 is inserted below the fixing plate 5. The connecting plate 56 is fixedly connected to the upper side of one side of the plug rod 55. The restoring spring 57 is fixedly connected between the bottom side of the connecting plate 56 and the fixing plate 5. The reinforcing rod 58 is inserted into one side of the plug rod 55. The limiting piece 59 is fixedly connected to the outside of the reinforcing rod 58. The spring 510 is fixedly connected between one side of the limiting piece 59 and the fixing plate 5. The spring 510 is located outside the reinforcing rod 58. A corresponding locking hole is opened on one side of the plug rod 55. A corresponding locking hole is opened on the bottom of the mounting block 41.
[0031] By adopting the above technical solution, when connecting the connecting wire 4, first pull the reinforcing rod 58 until one end of the reinforcing rod 58 is disengaged from the insert rod 55, and then pull the insert rod 55 downward. At this time, the top of the insert rod 55 no longer protrudes from the limiting groove 53, so the mounting block 41 can be inserted into the limiting groove 53 and the plug 42 can be connected to the slot 11, thereby realizing the connection of the connecting wire 4. Release the insert rod 55, and the insert rod 55 moves upward under the action of the restoring force of the restoring spring 57 and enters the locking hole at the bottom of the mounting block 41, thereby realizing the fixation of the connecting wire 4. At the same time, the reinforcing rod 58 enters the insert rod 55 under the action of the restoring force of the spring 510, thereby realizing the fixation of the insert rod 55, and thus strengthening the fixation effect of the connecting wire 4.
[0032] Working principle: During use, the cooling fan 31 dissipates heat from the power amplifier 1, and the filter plate 33 cools the air entering the power amplifier 1. Simultaneously, pulling the filter plate 33 forcefully removes it from the long slot 34 for cleaning, at which point the magnetic plate 36 separates from the magnetic block 35. Similarly, inserting the cleaned filter plate 33 into the long slot 34 causes the magnetic block 35 to attract the magnetic plate 36, thus securing the filter plate 33. When connecting the connecting wire 4, first pull the reinforcing rod 58 until one end of the reinforcing rod 58 detaches from the insertion rod. 55. When the plug rod 55 is pulled down, the top of the plug rod 55 no longer protrudes from the limiting groove 53. The mounting block 41 can then be inserted into the limiting groove 53, and the plug 42 can be connected to the slot 11, thereby connecting the connecting wire 4. When the plug rod 55 is released, the plug rod 55 moves upward under the restoring force of the restoring spring 57 and enters the locking hole at the bottom of the mounting block 41, thus fixing the connecting wire 4. At the same time, the reinforcing rod 58 enters the plug rod 55 under the restoring force of the spring 510, thus fixing the plug rod 55 and strengthening the fixing effect of the connecting wire 4.
[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
