Description

Technical Field

[0001] This utility model relates to the field of adapter technology, specifically to a two-stage power amplifier electronic architecture adapter that is easy to disassemble and maintain. Background Technology

[0002] The secondary power amplifier electronic architecture adapter is a key component connecting the various modules of a secondary power amplifier system. It is mainly responsible for signal conversion, distribution, and function control, enabling the adaptation and connection of signal interfaces of different specifications, ensuring the stable operation of the power amplifier system. In fields such as audio equipment and automotive electronics, the secondary power amplifier system needs to be compatible with a variety of signal sources and output devices. Without a dedicated adapter, the modules would be difficult to work together. Therefore, it is a core component that ensures the functional realization and flexible application of the secondary power amplifier system.

[0003] Traditional two-stage power amplifier adapters often employ integrated packaging or complex screw-fixed structures, requiring the disassembly of multiple components and even damage to the outer casing to access the internal core components. This results in time-consuming and difficult repairs. Furthermore, traditional adapters have low connector positioning accuracy, which can easily lead to misalignment and signal transmission failures. This not only affects the sound quality output of the power amplifier system but also increases subsequent maintenance costs. Therefore, we propose a two-stage power amplifier electronic architecture adapter that is easy to disassemble and repair. Utility Model Content

[0022] Working Principle: First, the adapter housing 1 serves as an external protective and support frame, providing a stable installation space for internal components. Its core is the PCBA board 2, which is the core carrier for signal conversion and control functions. To ensure stable installation and easy disassembly of the PCBA board 2, a PCBA board placement slot 13 is provided at the bottom inside the adapter housing 1. This slot contains three pre-set, triangularly distributed PCBA board fixing screw holes 10. During installation, the PCBA board 2 is inserted into the placement slot, and fixing screws 6 are passed through the corresponding holes on the PCBA board, precisely aligned with the fixing screw holes 10, and tightened to secure the PCBA board. For disassembly, only these three fixing screws need to be unscrewed to quickly remove the PCBA board for repair or replacement. The triangular screw design ensures installation stability while avoiding the cumbersome disassembly caused by too many screws. In terms of signal transmission and connection, the PCBA board 2 has board-end connector 1 3, board-end connector 2 4, and board connector 15 on both sides. All components are electrically connected to the PCBA board 2 via soldering or plug-in structures. The board-end connector 3 and board-end connector 4, due to their different diameters, can be adapted to different specifications of external signal input or output interfaces in the secondary power amplifier system. The board connector 15 is used for signal transmission of specific functions. To ensure accurate positioning of these connectors when docking with external devices, board-end positioning holes 11 and connector holes 12 are respectively opened at both ends inside the adapter housing 1. Board-end connector 3 and board-end connector 4 are embedded in the inner side of the board-end positioning hole 11, and board connector 15 is embedded in the inner side of the connector hole 12. The design of the positioning hole can not only fix the position of the connector, but also guide the external interface to be inserted accurately, avoiding signal transmission failure caused by docking deviation. At the same time, a button assembly is set at the front and rear ends of the adapter housing 1. This assembly consists of a toggle switch 7, a light guide 8, and a button group 9. The toggle switch 7 is installed in the switch slide groove opened at the front end of the adapter housing 1. It is electrically connected to the PCBA board 2 through a wire and is mainly used to switch the working mode of the adapter.The light guide 8 is located on one side of the toggle switch 7 and is also connected to the PCBA board 2. When the adapter is in different working states, the PCBA board 2 will output corresponding electrical signals to control the light guide 8 to emit light. The current working mode is intuitively displayed by the change in light color or brightness, which is convenient for users to observe. The button group 9 is installed on the back of the adapter housing 1 and consists of a pause / play button, a volume up button, and a volume down button. Each button is connected to the PCBA board 2 through a contact. When the user presses the corresponding button, the button contact forms a circuit with the circuit on the PCBA board and sends a control signal to the PCBA board 2, thereby realizing the adjustment of the playback status and volume control of the secondary power amplifier system. The toggle switch 7 and the button group 9 are correspondingly related to ensure that different control functions are consistent. The logical coordination between the components is optimized. Simultaneously, in terms of the casing sealing and bottom disassembly design, the bottom surface of the adapter casing 1 has a rectangular bottom cover positioning groove 14. The four corners of this positioning groove have bottom cover screw holes, while the four corners of the casing bottom cover 5 have pre-set mounting holes. During installation, the casing bottom cover 5 is inserted into the bottom cover positioning groove 14, aligning the bottom cover mounting holes with the bottom cover screw holes in the positioning groove. Then, the fixing screws 6 are passed through the mounting holes and screwed into the bottom cover screw holes to complete the fixing of the casing bottom cover, achieving a sealed protection for the bottom of the adapter. When it is necessary to inspect internal components, simply unscrew the fixing screws at the four corners of the casing bottom cover to quickly remove the bottom cover and further disassemble the PCBA board or other components. The entire disassembly process does not damage the overall structure, greatly improving maintenance efficiency.
