Description

Technical Field

[0001] This utility model relates to the technical field of power amplifier testing platforms, specifically a power amplifier testing energy recovery device test bench. Background Technology

[0002] A power amplifier, often shortened to "amplifier," is an amplifier that can produce maximum power output to drive a load under a given distortion rate. Power amplifiers play a pivotal role in the entire audio system, acting as a "coordinator" and, to a certain extent, determining whether the system can provide good sound quality.

[0003] For example, the Chinese patent with publication number CN210328417U, entitled "(A Power Amplifier)," includes: a housing; one end face of the housing is provided with a power interface, an input interface, an output interface, and a fast switch control for the transmission link; the inner wall of the housing is provided with annular support strips around its perimeter for placing an amplifier circuit board; the annular support strips on both ends of the inner wall of the housing are provided with openings for the amplifier circuit board circuitry to pass through; a limiting strip is also provided between the annular support strips and the bottom plate of the housing for restricting the routing of the amplifier circuit board circuitry; and a heat sink is installed on the outer surface of the top plate of the housing. This utility model provides a power amplifier that can effectively solve the problems of messy circuitry and poor heat dissipation in power amplifiers.

[0004] However, existing test benches for power amplifier testing energy recovery devices suffer from problems during operation, such as unstable placement of the power amplifier leading to poor contact at the testing connections. Therefore, they do not meet the current requirements. To address this, we propose a test bench for power amplifier testing energy recovery devices. Utility Model Content

[0005] The purpose of this utility model is to provide a test bench for a power amplifier testing energy recovery device, in order to solve the problem mentioned in the background art that the existing test benches for power amplifier testing energy recovery devices have the problem that the power amplifier is unstable during operation, resulting in poor contact at the test connection.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a power amplifier test energy recovery device test bench, comprising: a test bench body, wherein an energy recovery test device is disposed above one end of the test bench body;

[0007] Also includes:

[0008] A clamping and mounting cavity is installed inside the main body of the test bench. A clamping plate is provided on one side of the interior of the clamping and mounting cavity. One side of the clamping plate is elastically and telescopically connected to the main body of the test bench via a spring coil. A soft cover is provided on the upper side of the spring coil. The two sides of the soft cover are thermally fused to the clamping plate and the main body of the test bench, respectively.

[0009] Preferably, a storage slot is provided on one side of the upper surface of the test platform body, and there are two storage slots. The inner walls of the two storage slots are provided with buckle blocks, and the buckle blocks are fixedly connected to the inner walls of the storage slots.

[0010] Preferably, the energy recovery testing device has a mounting ring on one side, and there are two mounting rings. A detection handle is installed inside the two mounting rings, and there are two detection handles. A connecting wire is provided on the lower end face of the two detection handles, and one end of the connecting wire is provided with an access terminal.

[0011] Preferably, the front end of the energy recovery testing device is provided with a display screen, the lower side of the display screen is provided with buttons, and a display directional needle is provided on one side of the buttons.

The interior of the maintenance plate is provided with heat dissipation holes, and a number of heat dissipation holes are provided, all of which are integrally formed with the maintenance plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model installs the power amplifier with detection inside the clamping and mounting cavity. Through the set clamping plate and spring ring, the power amplifier is effectively clamped by the spring's reaction force after entering, thus firmly fixing the power amplifier. It can also fix power amplifiers of different sizes. After fixing, the detection handle is removed from the storage slot, and then the connection end is installed in the energy recovery testing equipment's connection hole. This allows the two detection handles to test the power amplifier with detection, effectively avoiding the displacement of the object's position during the testing process. It also effectively avoids the problem of unstable placement of the power amplifier and poor contact at the detection connection point that occurs in existing test benches used for power amplifier energy recovery devices during operation.
