Description

Technical Field

[0001] This utility model relates to the field of power amplifier testing equipment technology, specifically a fixture for testing power amplifiers. Background Technology

[0002] A power amplifier, also known as a power amplifier, is a device that converts audio signals into sound. Simply put, it refers to a speaker enclosure or subwoofer enclosure with a built-in power amplifier that amplifies the audio signal before the speaker itself reproduces the sound, making it louder. Typically, during the manufacturing process, users are required to perform noise testing on the speaker amplifier.

[0003] However, in the existing technology, when staff test each speaker amplifier, they need to complete a connection with the speaker amplifier, which increases the workload of the staff and reduces the efficiency of the test. This needs to be further improved.

[0004] Therefore, based on the above-mentioned technical problems, it is necessary for those skilled in the art to develop a fixture for testing power amplifiers. Utility Model Content

[0005] The purpose of this invention is to provide a fixture for testing power amplifiers, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A fixture for testing a power amplifier includes a support plate. Connecting components are provided at the four corners of the bottom surface of the support plate, and limiting components are provided on the top surface of the support plate. Multiple through holes are opened on the top surface of the support plate, and a bolt is provided in each of the multiple through holes. The bottom end of each of the multiple bolts is connected to a wire, and the other end of each of the multiple wires is connected to a lead.

[0008] As a preferred technical solution, the support plate is rectangular in shape and made of PVC material.

[0009] As a preferred technical solution, the connecting component includes a U-shaped block, which is installed at the bottom corner of the support plate. An L-shaped block is fixed inside the U-shaped block by bolt two, and a strip hole is opened on the top surface of the L-shaped block.

[0010] As a preferred technical solution, the U-shaped block has multiple threaded holes on one side, and the bolt is threaded into one of the threaded holes.

[0011] As a preferred technical solution, the limiting component includes two L-shaped blocks 2 and two L-shaped blocks 3. The two L-shaped blocks 2 are symmetrically installed on the top surface of the support plate, and the two L-shaped blocks 3 are symmetrically installed on the top surface of the support plate. The two L-shaped blocks 2 and the two L-shaped blocks 3 form a cavity.

[0012] As a preferred technical solution, the top surface of the support plate is provided with a limiting block located between the L-shaped block two and the L-shaped block three.

[0013] As a preferred technical solution, a conductive block is installed on the bottom surface of the support plate, which is in contact with one of the plurality of bolts, and the conductive block is electrically connected to the plurality of wires.

[0014] As a preferred technical solution, the bottom surface of each of the L-shaped blocks is provided with multiple friction columns.

[0015] Compared with the prior art, the beneficial effects of this utility model are: with this utility model, the operator can complete the test of the power amplifier by connecting to the three leads. When another power amplifier needs to be tested, it is only necessary to separate the fixture from the power amplifier and then place the power amplifier to be tested on the fixture. The user does not need to repeatedly connect to the power amplifier to be tested, which reduces the workload of the operator and improves the efficiency of the test. Attached Figure Description

[0021] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely intended to provide a better understanding of this utility model by illustrating examples.

[0022] like Figure 1-4 As shown, this utility model provides a fixture solution for testing power amplifiers: it includes a support plate 1. The operator places the power amplifier to be tested on the top surface of the support plate 1. The support plate 1 is rectangular in shape and is made of PVC material. Using this material reduces the weight of the entire fixture and ensures the safety of the user by being non-conductive.

[0023] In this embodiment, connecting components are provided at the four corners of the bottom surface of the support plate 1. Taking one set of connecting components as an example, the connecting component includes a U-shaped block 6. The U-shaped block 6 is installed at the corner of the bottom surface of the support plate 1, with the opening of the U-shaped block 6 facing downward. Two threaded holes 9 are opened on one side of the U-shaped block 6, and bolts 2 are threaded into the two threaded holes 9. An L-shaped block 1 7 is inserted into the U-shaped block 6. After adjusting the position of the L-shaped block 1 7, the inner ends of the two bolts 2 are abutted against the L-shaped block 1 7. At the same time, a strip hole 8 is opened on the top surface of the L-shaped block 1 7. The operator can prepare bolts 3 in advance, pass the bolts 3 through the strip hole 8 respectively, and fix the support plate 1 in the pre-set position.

[0024] In this embodiment, a limiting component is provided on the top surface of the support plate 1. The limiting component includes two L-shaped blocks 10 and two L-shaped blocks 12. The two L-shaped blocks 10 are symmetrically installed on the top surface of the support plate 1 and are arranged along the width direction of the support plate 1. The two L-shaped blocks 12 are symmetrically installed on the top surface of the support plate 1. The two L-shaped blocks 10 and the two L-shaped blocks 12 form a cavity 13. When the operator puts the power amplifier to be tested into the cavity 13, the two L-shaped blocks 10 and the two L-shaped blocks 12 have a limiting function.

[0025] Two limiting blocks 14 are installed on the top surface of the support plate. The two limiting blocks 14 are located between the two L-shaped blocks 10 and the two L-shaped blocks 12 respectively. The limiting blocks 14, L-shaped blocks 10 and L-shaped blocks 12 complement each other and have a limiting effect on the power amplifier.

[0026] In this embodiment, a plurality of through holes 2 are provided on the top surface of the support plate 1. There are three through holes 2, which are vertically opened and arranged along the width direction of the support plate 1. A bolt 3 is installed in each of the three through holes 2. At the same time, a wire 4 is connected to the bottom end of each of the three bolts 3. The three wires 4 are fixed to the bottom surface of the support plate 1. A lead 5 is connected to the other end of each wire 4. When using the fixture, the user places the power amplifier between the two L-shaped blocks 10 and the two L-shaped blocks 12. At this time, the three connection ports of the power amplifier are electrically connected to the three bolts 3. The operator then connects the power amplifier to the three leads 5 to complete the test of the power amplifier. When another power amplifier needs to be tested, it is only necessary to separate the fixture from the power amplifier and then place the power amplifier to be tested on the fixture. The user does not need to repeatedly connect the power amplifier to be tested, which reduces the workload of the operator and improves the efficiency of the test.

[0027] In this embodiment, a conductive block 15 is installed on the bottom surface of the support plate 1, which is in contact with three bolts 3. The three conductive blocks 15 are electrically connected to multiple wires 4. At the same time, an insulator is provided on the conductive block 15.

[0028] In this embodiment, four friction posts 16 are provided on the bottom surface of each of the multiple L-shaped blocks 7. The four friction posts 16 are in contact with the placement position to reduce the situation where the clamp moves spontaneously when using the clamp.
