Technical Field

[0001] The utility model relates to the technical field of power amplifier detectors, and more specifically, to a modular power amplifier detector. Background Art

[0002] In the power grid industry, especially in the power grid distribution test industry, power amplifier detectors are widely used. A power amplifier detector is a high-performance linear power amplifier developed for power system simulation, which can detect internal power parameters and processing parameters. It can help users measure various key parameters of the power amplifier, including but not limited to output power, frequency response, total harmonic distortion, signal-to-noise ratio, and input and output impedance, etc.

[0003] Currently, common portable power amplifier detectors are large in size and complex in structure, making them very inconvenient to carry and transport. Generally, they are cooled by a cooling fan on the heat dissipation module, and the cooling effect is not good, which will lead to a poor internal operating environment of the detector. At the same time, the heat dissipation module is fixedly installed inside the power amplifier detector. When subsequent maintenance, replacement or adjustment is required, the whole detector needs to be disassembled, the operation is cumbersome, and both installation and disassembly are time-consuming and laborious, with high operation difficulty and low efficiency, and the use effect is not good.

[0004] Therefore, it is necessary to provide a modular power amplifier detector to solve the above technical problems. Summary of the Utility Model

It can be seen that the production, assembly and disassembly of the power amplifier detector are relatively convenient, and it has the characteristics of small size, very convenient to carry and transport.

[0019] 2. Under the action of the cooling fan in this solution, external air can be efficiently sucked into the chassis of this power amplifier detector through the first air inlet grille hole and the second air inlet grille hole, and discharged from the air outlet grille hole on the rear panel after passing through the gaps of the heat dissipation fins; and the exhaust fan on the rear panel will actively extract the hot air inside, which can improve the speed of discharging the hot air inside the chassis, effectively prevent the situation that the hot air inside the chassis cannot be discharged in time, resulting in high temperature affecting the normal operation of the components inside the chassis, greatly reducing the operating temperature of the equipment inside the chassis of this power amplifier detector, and enabling a better operating environment inside.

[0020] 3.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the protection scope of the present invention.

[0035] It should be noted that if there are directional indications (such as up, down, left, right, front, back,...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If the specific posture changes, the directional indications will also change accordingly.

[0036] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0037] Please refer to Figures 1-10, A modular power amplifier detector, comprising a housing and a heat dissipation module 10. The housing is composed of a front panel 1, a rear panel 2, an upper cover plate 3, a lower cover plate 4, a left panel 5 and a right panel 6, and further includes: a frame 7, detachably disposed between the left panel 5 and the right panel 6, and an installation plate 8 is provided on the frame 7; a connection seat 9, detachably installed on the installation plate 8, a slide rail 11 is provided on the connection seat 9, and a chute 12 is opened on the slide rail 11; a slide plate 13 slidably adapted to the chute 12 is provided on the heat dissipation module 10; a plurality of exhaust fans 14 are provided on the rear panel 2. A first air inlet grille hole 25 and a second air inlet grille hole 26 are respectively opened on the upper cover plate 3 and the lower cover plate 4, auxiliary grille holes 27 are provided on both the left panel 5 and the right panel 6, and an air outlet grille hole 31 is further opened on the rear panel 2. A display panel 28 is further installed on the front panel 1, and a side fan is further provided on the left panel 5. One end of the heat dissipation module 10 is provided with a cooling fan 29, and a plurality of heat dissipation fins 30 are provided on the heat dissipation module 10.

[0038] During production and assembly, after removing the front panel 1, the upper cover plate 3 and the lower cover plate 4, at this time, a plurality of heat dissipation modules 10 are installed along the slide rail 11, so that the slide plate 13 on the heat dissipation module 10 is limited and slid along the chute 12 of the slide rail 11 to move it to a specified position. The left panel 5 and the right panel 6 are locked on the frame 7, and after fixing the rear panel 2, then the lower cover plate 4, the front panel 1 and the upper cover plate 3 are installed in sequence, thus completing the assembly of the chassis of this power amplifier detector. It can be seen that the production and assembly of the power amplifier detector are relatively convenient, and it has the characteristics of small volume, convenient loading and unloading, and very convenient carrying and transportation.

[0039] Air intake is carried out through the first air intake grille holes 25 on the upper cover plate 3 and the second air intake grille holes 26 on the lower cover plate 4. The heat dissipation module 10 integrates an aluminum radiator. Under the action of the cooling fan 29, external air can be efficiently and actively sucked into the chassis of this power amplifier detector through the first air intake grille holes 25 and the second air intake grille holes 26. After passing through the gaps between the cooling fan 29 and the heat dissipation fins 30, it is discharged through the air outlet grille holes 31 on the rear panel 2. And through the multiple exhaust fans 14 on the rear panel 2, the hot air inside will be actively extracted, thereby increasing the speed at which the hot air in the chassis is discharged, greatly avoiding the situation where the hot air stays in the chassis for a long time, effectively preventing the situation where the hot air in the chassis cannot be discharged in time, which affects the normal operation of the components in the chassis, further improving the heat dissipation effect of the chassis, greatly reducing the operating temperature of the equipment inside the chassis of this power amplifier detector, and enabling a better operating environment inside. And when the first air intake grille holes 25 are blocked, air intake and heat dissipation can be carried out through the second air intake grille holes 26 on the lower cover plate 4. Similarly, when the second air intake grille holes 26 are blocked, air intake and heat dissipation can be carried out through the first air intake grille holes 25 on the upper cover plate 3, that is, it can ensure that the air intake and heat dissipation equipment is not affected by different placement directions and has strong flexibility. The auxiliary grille holes 27 can assist in the auxiliary heat dissipation of the chassis of this power amplifier detector, improve the air circulation effect, and thus improve the heat dissipation effect.

[0040] When it is necessary to debug, repair, or replace the heat dissipation module 10, the front panel 1, the upper cover plate 3, and the lower cover plate 4 can be removed at this time, and then each heat dissipation module 10 can be pulled out from the frame 7, so that each heat dissipation module 10 can be debugged, repaired, and replaced. The operation is simple and convenient, avoiding the cumbersome and complex disassembly situation where the current heat dissipation module 10 is integrally fixed inside, with a small workload, convenient assembly, reducing a lot of labor intensity and working time, greatly improving the work efficiency, and having a good use effect.

[0041] The front panel 1 is also provided with an equipment operation indicator light, a fault indicator light, and a communication network port. The equipment operation indicator light is used for indicating the power supply and operation of the equipment. The fault indicator light is used for flashing to indicate operation errors in case of equipment operation failures. The communication network port is used for connecting to other systems or computers for information interaction. The rear panel 2 is also provided with a power interface panel and a communication interaction interface panel. The power interface panel is used for connecting the 220V AC power supply for the operation of the equipment. The communication interaction interface panel is used for accessing the signal data and debugging data of other test instruments. The power interface panel and the communication interaction interface panel are connected to each heat dissipation module 10, and modular operation is used, which is convenient for on-site staff to repair, debug, and replace. And each heat dissipation module 10 can be pulled out of the chassis of the detector and reinstalled into the chassis without interfering with each other, which can clearly locate the problem source and then solve it. The advantages and effects of the power amplifier detector of this application are more obvious.

[0042] A display panel 28 is also installed on the front panel 1, which is convenient for displaying various data when the power amplifier detector is in use. The staff can intuitively observe the detection data at this time, and it is convenient for the staff to control the detector.

[0043] In this embodiment, preferably, please refer to Figures 4-5 and Figure 8 , a plurality of limiting holes 15 are evenly formed in the mounting plate 8, an elastic clamping block 16 adapted to the mounting plate 8 is arranged on the connecting seat 9, and a pin shaft 17 adapted to the limiting holes 15 is further arranged on the connecting seat 9. When assembling this chassis, after moving the connecting seat 9 and the slide rail 11 to the designated position of the mounting plate 8, the pin shaft 17 on the connecting seat 9 can be inserted into the limiting holes 15 at the corresponding positions, and at this time, the position of the connecting seat 9 in the front-back, left-right directions can be restricted; then move the connecting seat 9 and the elastic clamping block 16 up and down. After the elastic clamping block 16 is squeezed by the mounting plate 8, it will deform. Finally, after the elastic clamping block 16 is no longer pressed, it will recover its deformation. At this time, the elastic clamping block 16 can be stuck on the mounting plate 8, so that the position of the connecting seat 9 in the up-down direction can be restricted. Furthermore, at this time, the connecting seat 9 can be fixedly restricted on the mounting plate 8, and the installation and subsequent disassembly are very convenient and fast. And the position of the connecting seat 9 on the mounting plate 8 can be adjusted according to actual needs, with strong flexibility, meeting the needs in different situations, wide application range and strong practicability.

[0044] In this embodiment, preferably, please refer to Figures 4-5 and Figure 8 , a limiting groove 23 is further formed in the slide rail 11, and an insertion plate 24 slidably adapted to the limiting groove 23 is arranged on the connecting seat 9. The limiting groove 23 is in a "convex" shape. By inserting the insertion plate 24 into the limiting groove 23 of the slide rail 11, the connecting seat 9 can be connected to the slide rail 11; when it is necessary to disconnect the connection between the connecting seat 9 and the slide rail 11, just pull out the connecting seat 9 from the slide rail 11, and the operation is simple and convenient.

[0045] In this embodiment, preferably, please refer to Figures 4-9 , two limiting components 18 are arranged on each slide rail 11 for restricting the position of the sliding plate 13; the limiting component 18 includes a vertical plate 181 arranged on the slide rail 11; a limiting rod 182 movably penetrating through the vertical plate 181, one end of the limiting rod 182 is provided with a pull rod 183, and the other end is a slope; an elastic member 184, one end of which is connected to the pull rod 183 and the other end is connected to the vertical plate 181. The elastic member 184 in this application is a spring.

[0046] When the heat dissipation module 10 is inserted along the slide rail 11, the slide plate 13 on the heat dissipation module 10 will move along the slide groove 12 of the slide rail 11, and the end of the slide plate 13 will squeeze the outer limit rod 182 after contacting it, and the limit rod 182 will move outward and stretch the elastic member 184. When the heat dissipation module 10 and the slide plate 13 move to the specified position, the outer limit rod 182 is no longer squeezed, and the elastic force of the elastic member 184 will drive the limit rod 182 to move back to the initial position. At this time, the limit rod 182 will block the outer end of the slide plate 13, and the inner end of the slide plate 13 will be supported by the inner limit rod 182, so that the position of the slide plate 13 and the heat dissipation module 10 can be limited, which greatly prevents the subsequent movement of the heat dissipation module 10 and ensures its stability during operation or movement. At the same time, it also avoids the situation of fixing the heat dissipation module 10 by other subsequent fixing methods, saving time and labor, simplifying the operation steps, and reducing the production cost. It has a good use effect and can be promoted.

[0047] In this embodiment, preferably, please refer to Figures 3-6 The slide rail 11 is provided with a guide rail 19, a guide seat 20 is slidably provided on the guide rail 19, a vertical plate 181 is connected to the guide seat 20, a plurality of fixing holes 21 are provided on the guide rail 19, and a fastening bolt 22 threadedly connected with the fixing hole 21 is provided on the guide seat 20. When the fastening bolt 22 is loosened, the guide seat 20 can be driven to slide along the guide rail 19, so that the position of the vertical plate 181 and the limit rod 182 can be adjusted, and the adjustment can be made according to the different positions or lengths of the slide plate 13, which is suitable for the adjustment and use of heat dissipation modules 10 of different specifications and in actual situations, and has strong flexibility. After the adjustment is completed, the fastening bolt 22 is tightened again to cooperate with the fixing hole 21 at the corresponding position to fix the position of the guide seat 20 and the limit assembly 18.
