Description

Technical Field

[0001] This utility model relates to the field of power amplifier technology, and more specifically, to an external control connector for a power amplifier. Background Technology

[0002] In modern audio systems, the power amplifier is responsible for amplifying audio signals and driving speakers to output high-quality sound. External control connectors connect to devices such as remote controls, smart control panels, and computers, allowing users to adjust parameters such as power amplifier volume, channel balance, and sound effect modes. It is a key component for operating the power amplifier.

[0003] However, existing external control connectors for power amplifiers generally suffer from insecure connections and are prone to detachment under external force. In daily life, when users adjust the position of speakers, organize cables, or touch the connecting cables, the connectors may detach from the amplifier interface due to slight external force. This not only interrupts audio control operations but may also cause momentary incorrect adjustments to equipment parameters, greatly affecting the user experience. In special application environments, such as professional stage performances and recording studios, the stability of speaker connections is extremely important. However, due to their insecure nature, existing connectors are very likely to detach during equipment movement or stage vibrations, leading to interruption of audio signal control, affecting performance effects or recording quality, and in severe cases, causing equipment failure and resulting in huge economic losses. In addition, frequent detachment of connectors will accelerate the wear and tear on the interface and itself, shortening the service life of the equipment. Improper replugging and plugging can also cause static electricity, damaging the internal electronic components of the power amplifier. Therefore, there is an urgent need to improve the existing connectors. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 8As shown, this utility model provides an external control connector for a power amplifier, comprising: Amplifier 1, with interface 2 fixedly installed on the front of amplifier 1, and a clip 3 fixedly installed on the outer surface of interface 2; A connecting mechanism is located inside interface 2; The connecting mechanism includes a connector 4, which is movably inserted into the interior of the interface 2. A movable ring 5 is movably sleeved on the outer surface of the connector 4. A round rod 6 is fixedly sleeved inside the movable ring 5. A moving block 7 is movably sleeved on the outer surface of the round rod 6. The interior of the moving block 7 is movably sleeved with the outer surface of the connector 4. A first spring 8 is movably sleeved on the outer surface of the moving block 7. One end of the first spring 8 is fixedly connected to the outer surface of the movable ring 5, and the other end of the first spring 8 is fixedly connected to the interior of the moving block 7.

[0020] When connector 4 is inserted into interface 2, the operator pushes the moving block 7. The moving block 7 will move backward under the limit of the round rod 6. At this time, the first spring 8 will be compressed. During this process, the notch at the rear of the moving block 7 will pass over the locking block 3. When the rear end of the moving block 7 moves to the rear of the outer surface of interface 2, the locking block 3 will be located inside the moving block 7. At this time, the operator twists the moving block 7. The moving block 7 will drive the movable ring 5 to rotate along the outer surface of the power amplifier 1 through the round rod 6. At the same time, the interior of the moving block 7 will contact the outer surface of the locking block 3 during rotation. At this time, the locking block 3 will abut against the interior of the moving block 7. The moving block 7 and the locking block 3 will cooperate to lock the interface 2 and connector 4, so that the connector 4 and the power amplifier 1 can be securely connected.

[0021] Among them, the front end of the outer surface of the moving block 7 is fixedly installed with an anti-slip strip 9, and the rear end of the outer surface of the moving block 7 is fixedly sleeved with a ratchet 14.

[0022] Due to the design of the anti-slip strip 9, the friction of the outer surface of the moving block 7 will be increased, which will make it easier for the operator to push and twist the moving block 7. When the moving block 7 moves, the ratchet 14 will move under the drive of the moving block 7.

[0023] Among them, a fixing block 10 is fixedly installed on the back of the power amplifier 1, and a movable block 11 is movably connected inside the fixing block 10.

[0024] Because the movable block 11 is internally connected to the fixed block 10, the movable block 11 can only move up and down along the inside of the fixed block 10.

[0025] Among them, a lever 12 is fixedly installed on the outer surface of the movable block 11, and the lever 12 is slidably connected to the inside of the front of the fixed block 10.

[0026] Due to the design of the lever 12, the operator can move the movable block 11 up and down along the interior of the fixed block 10 by moving the lever 12.

[0027] The bottom end of the movable block 11 is fixedly equipped with a pawl 13, and the outer surface of the pawl 13 is movably connected to the inner part of the bottom end of the fixed block 10.

[0028] When the movable block 11 moves up and down along the inside of the fixed block 10, the pawl 13 will move up and down under the action of the movable block 11.

[0029] The top of the movable block 11 is fixedly installed with a second spring 15, and the top of the second spring 15 is fixedly connected to the inside of the fixed block 10.

[0030] When the movable block 11 moves upward, it will compress the second spring 15. Due to the design of the second spring 15, it will have a good restoring effect on the overall movement of the movable block 11.

[0031] The amplifier 1 has a rubber foot pad 16 fixedly installed at the bottom and a heat dissipation vent 17 at the top.

[0032] Due to the design of the rubber feet 16, the amplifier 1 can be placed stably on other flat surfaces. The material of the rubber feet 16 will increase the friction at the bottom of the amplifier 1. The design of the heat dissipation vent 17 will provide good heat dissipation for the amplifier 1.

[0033] The amplifier 1 has a fixed frame 18 fixedly installed on its top, and a filter 19 is slidably connected inside the fixed frame 18. The filter 19 is located above the top of the heat dissipation vent 17.

[0034] Because the filter 19 is slidably connected to the inside of the fixed frame 18, the filter 19 can move left and right along the inside of the fixed frame 18. Due to the design of the filter 19, dust can be prevented from entering the inside of the power amplifier 1 from the heat dissipation port 17.

[0035] Among them, a pull ring 20 is fixedly installed on the right side of the filter screen 19, and a rubber ring 21 is fixedly sleeved inside the pull ring 20.

[0036] The design of the pull ring 20 allows the operator to pull the filter screen 19 out of the fixed frame 18 by pulling the pull ring 20, which makes it easier for the operator to disassemble and clean the filter screen 19. The design of the rubber ring 21 makes it more comfortable for the operator to pull the pull ring 20.

[0037] Working principle and usage process of this utility model: When the operator needs to connect the power amplifier 1 to the connector 4, the operator first inserts the connector 4 into the interface 2. After the connector 4 is firmly inserted into the interface 2, the operator pushes the moving block 7. Due to the design of the round rod 6, the movement of the moving block 7 is limited. At this time, the moving block 7 will move backward along the outer surface of the round rod 6. During this process, the moving block 7 will compress the first spring 8. When the rear end of the moving block 7 moves to the rear of the outer surface of the interface 2, because the rear end of the moving block 7 has a notch corresponding to the locking block 3, Therefore, at this time, the locking block 3 will be located inside the moving block 7. The operator will then twist the moving block 7, causing the moving block 7 to drive the round rod 6 to rotate along the outer surface of the connector 4. At the same time, the round rod 6 will rotate under the drive of the moving block 7. At this time, the round rod 6 will drive the movable ring 5 to rotate along the outer surface of the power amplifier 1. During this process, the back of the locking block 3 will abut against the inside of the moving block 7. At this time, the moving block 7 will cooperate with the locking block 3 to lock the movement of the interface 2 and the connector 4, thereby realizing the function of making the connector 4 and the power amplifier 1 securely connected.

[0038] When the rear end of the moving block 7 moves to the rear of the outer surface of the interface 2, the ratchet 14 will move to the bottom of the pawl 13 under the drive of the moving block 7. At this time, the outer surface of the ratchet 14 will contact the bottom of the pawl 13. When the moving block 7 rotates, it will drive the ratchet 14 to rotate. At this time, the outer surface of the ratchet 14 will squeeze and push the pawl 13 during rotation, so that the pawl 13 drives the movable block 11 to move upward along the inside of the fixed block 10. During this process, the movable block 11 will compress the second spring 15. When the moving block 7 stops rotating, the ratchet 14 will stop squeezing the pawl 13. Due to the elastic force of the second spring 15, the second spring 15 will drive the pawl 13 to return downward through the movable block 11. Due to the design of the pawl 13 and the ratchet 14, the ratchet 14 can only rotate in the same direction, thereby ensuring the stability of the connection between the moving block 7 and the locking block 3.

[0039] When the operator needs to remove connector 4 from amplifier 1, the operator first pulls up the lever 12, causing the lever 12 to drive the pawl 13 upward through the movable block 11. At this time, the pawl 13 will release its obstruction to the ratchet 14 during the upward movement, allowing the operator to drive the moving block 7 to rotate in the opposite direction. When the notch at the rear end of the moving block 7 aligns with the locking block 3 during rotation, the operator releases the moving block 7. Due to the elastic force of the first spring 8, the moving block 7 will move forward to reset under the action of the first spring 8. At this time, the moving block 7 will release its connection with the locking block 3 during the forward movement, thereby releasing the lock on interface 2 and connector 4, allowing connector 4 to be pulled out of interface 2.

[0040] Due to the design of the heat dissipation vent 17, the power amplifier 1 can be effectively cooled. Due to the design of the filter 19, the heat dissipation vent 17 can be effectively dustproofed. After the power amplifier 1 has been running for a long time, a lot of dust will accumulate on the filter 19. At this time, the operator needs to remove the filter 19. The operator inserts his / her finger into the pull ring 20 and pulls the pull ring 20. The filter 19 will then move to the right along the inside of the fixed frame 18 under the action of the pull ring 20. Then the filter 19 will be pulled out from the inside of the fixed frame 18, thus realizing the function of making it easy for the operator to disassemble and clean the filter 19.
