Technical Field

[0001] The utility model relates to the technical field of power amplifier IC limiting brackets, in particular to a power amplifier IC limiting bracket structure. Background Art

[0002] Amplifier IC, or audio power amplifier integrated circuit, is an indispensable part of all kinds of audio equipment. Its task is to amplify the weak signal input by the sound source equipment and generate a large enough current to drive the speaker to reproduce the sound. Due to considerations of power, impedance, distortion, dynamics, different usage ranges and control adjustment functions, different amplifier ICs have different internal signal processing, circuit design and production processes.

[0003] At present, the fixing bracket of the power amplifier IC cannot effectively limit the height of the power amplifier, resulting in the deviation of the screw hole position, increasing the difficulty of locking, or requiring additional limiting tooling to control the height of the power amplifier IC when the power amplifier IC is plugged in, resulting in increased costs. Therefore, a power amplifier IC limiting bracket structure is urgently needed to solve the above problems. Utility Model Content

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] Through the above technical solution: the support component together with the power amplifier IC is directly assembled into the inside of the matching groove on the top of the circuit board through the matching plate, thereby completing the installation of the entire bracket structure.

[0011] The utility model is further configured that a circular hole is opened on one side outer wall of the vertical plate, a threaded seat is fixedly connected to one side outer wall of the vertical plate, and the center of the threaded seat is the same as the center of the circular hole, the positioning hole and the through hole.

[0013] The utility model is further configured that arc surface ends are arranged on both sides of the bottom end of the matching plate, and limiting components are arranged on both sides of the matching plate.

[0017] The utility model is further configured that the cross section of the limiting frame is a right-angled triangle, and the short right-angled side of the limiting frame is in contact with the outer wall of the bottom of the circuit board.

[0018] Through the above technical solution: when the limit frame is inserted into the matching groove together with the matching plate, the limit frame moves into the installation groove, which can ensure that the limit frame and the matching plate can stably pass through the matching groove.

[0019] The utility model is further configured that the springs are distributed at equal distances inside the installation groove.

[0025] 2. In the utility model, it is possible to ensure that the support assembly is stably installed on the circuit board. Specifically, a limit assembly is provided. When the mating plate is inserted into the mating groove, the limit frame squeezes the spring and shrinks to the inside of the installation groove. When the mating plate and the limit frame pass through the mating groove as a whole, the spring in the squeezed state will be reset immediately, so that the limit frame can be popped out from the installation groove. At this time, the limit frame can effectively prevent the mating plate from detaching from the mating groove, thereby playing a good limiting and fixing role, thereby ensuring that the support assembly can be stably installed on the circuit board.

First, the power amplifier IC3 is assembled into the interior of the support assembly 2. At this time, the power amplifier IC3 can be limited and fixed in the X-axis and Y-axis directions by the second side plate 2005, the second limiting plate 2007 and the first limiting plate 2006 in the support assembly 2. The support assembly 2 can effectively limit the height of the power amplifier IC3, which is convenient for subsequent staff to lock and fix it with screws, so that the screw hole position of the power amplifier IC3 will not be offset when it is fixed, and the entire bracket structure is easy to assemble, the limiting effect is effective, and the cost is low;

[0039] Pin 6 at the bottom of the power amplifier IC3 is fixed on the circuit board 1.

[0040] In order to ensure that the support component 2 and the power amplifier IC 3 can be stably installed on the circuit board 1, refer to Figure 1-Figure 2 , both sides of the vertical plate 2001 are fixedly connected with the first side plate 2003, and the bottom of the first side plate 2003 is fixedly connected with the matching plate 2002, one end of the matching plate 2002 is inserted into the matching groove 4 opened on the top of the circuit board 1, and the support component 2 together with the power amplifier IC3 are directly assembled into the inside of the matching groove 4 on the top of the circuit board 1 through the matching plate 2002, thereby completing the installation of the entire bracket structure.

[0041] In order to ensure that the subsequent power amplifier IC3 can be stably locked on the support component 2, refer to Figure 3 A circular hole 8 is opened on the outer wall of one side of the vertical plate 2001, and a threaded seat 2004 is fixedly connected to the outer wall of one side of the vertical plate 2001. The center of the threaded seat 2004 is the same as the center of the circular hole 8, the positioning hole 5, and the through hole 7. The power amplifier IC3 can be fixed to one side of the supporting assembly 2 by bolts.

[0042] Working principle: When in use, the staff first assembles the power amplifier IC3 into the interior of the support component 2. At this time, the power amplifier IC3 can be limited and fixed in the X-axis and Y-axis directions through the second side plate 2005, the second limiting plate 2007 and the first limiting plate 2006 in the support component 2. After the power amplifier IC3 is fixed on the support component 2, the staff assembles the support component 2 together with the power amplifier IC3 directly into the interior of the matching groove 4 at the top of the circuit board 1 through the matching plate 2002, thereby completing the installation of the entire bracket structure. At this time, the support component 2 can effectively limit the height of the power amplifier IC3, which is convenient for the subsequent staff to lock and fix it with screws, so that the screw hole position of the power amplifier IC3 will not be offset when it is fixed, and the entire bracket structure is easy to assemble, the limiting effect is effective, and the cost is low.

[0043] Example 2

[0044] Reference Figure 4 Figure 7 , a power amplifier IC limit bracket structure. Compared with Example 1, this embodiment also includes arc ends 10 on both sides of the bottom end of the matching plate 2002, and limit components are set on both sides of the matching plate 2002. The arc ends 10 can ensure that the matching plate 2002 can be more convenient for the staff to more easily insert into the inside of the matching slot 4.

[0045] In order to prevent the mating plate 2002 from falling off from the circuit board 1 after installation, refer to Figure 4 Figure 7 The limit assembly includes mounting grooves 13 provided on the outer walls on both sides of the mating plate 2002, and a spring 14 is fixedly connected to the inner wall of one side of the mounting groove 13. The end of the spring 14 away from the mounting groove 13 is fixedly connected to the limit frame 9. In the process of inserting the mating plate 2002 into the mating groove 4, the limit frame 9 will squeeze the spring 14 and shrink to the inside of the mounting groove 13. When the mating plate 2002 and the limit frame 9 pass through the inside of the mating groove 4 as a whole, the spring 14 in the squeezed state will be immediately reset, so that the limit frame 9 can be popped out from the inside of the mounting groove 13. At this time, the limit frame 9 can effectively prevent the mating plate 2002 from detaching from the inside of the mating groove 4, which plays a good limiting and fixing role, ensuring that the support assembly 2 can be stably installed on the circuit board 1.

[0046] In order to ensure that the limiting frame 9 can pass through the inside of the matching groove 4 together with the matching plate 2002, refer to Figure 4 Figure 5 The cross section of the limit frame 9 is a right triangle, and the short right-angled side of the limit frame 9 contacts the outer wall of the bottom of the circuit board 1. When the limit frame 9 is inserted into the mating groove 4 together with the mating plate 2002, the limit frame 9 moves into the installation groove 13, which can ensure that the limit frame 9 and the mating plate 2002 can stably pass through the inside of the mating groove 4.

[0047] In order to make the elastic force on one side of the limit frame 9 relatively uniform, refer to Figure 6 Figure 7 The springs 14 are evenly distributed inside the mounting groove 13 , so that the elastic force generated by the springs 14 can act evenly on the limiting frame 9 .

[0048] In order to ensure that the limit frame 9 can be stably retracted and ejected, refer to Figure 6 Figure 7 The inner walls on both sides of the mounting groove 13 are provided with a slide groove 12, and a slider 11 is slidably connected inside the slide groove 12. The slider 11 is fixedly connected to the limit frame 9. By sliding the slider 11 inside the slide groove 12, the limit frame 9 can be well limited and guided, ensuring that the limit frame 9 can be stably retracted and popped out.
