Description

Technical Field

[0001] This invention relates to the field of analyzer equipment, and in particular to a portable time-frequency synchronization analyzer. Background Technology

[0002] The time and frequency synchronization analyzer can perform high-precision measurement, analysis, and evaluation of various types of time information and clock frequency interfaces. It can conveniently measure the time and frequency synchronization performance of time and frequency synchronization equipment, 3G / 4G / 5G mobile backhaul networks, telecommunications IP bearer networks / access networks, smart substations, high-speed railways, rail transit, air transport, satellite time synchronization, ship calibration, and traditional billing systems.

[0003] The operation of a time-frequency synchronization analyzer requires the use of control integrated circuits. These integrated circuits contain power management chips and multiple electrolytic capacitors, which frequently fail under actual operating conditions. The specific reasons are as follows:

[0004] ① Electrolytic capacitors generate a lot of heat, and prolonged exposure to high temperatures can cause them to explode or leak. Additionally, the electrolyte in an electrolytic capacitor will evaporate over time, leading to capacitor failure. Therefore, electrolytic capacitors should be replaced promptly if they have been used for an extended period.

[0005] ② The power management chip generates a lot of heat. Maintaining a high temperature for a long time will cause the temperature to rise too high, which will damage the chip. At the same time, excessive instantaneous current will also damage the power management chip.

[0006] In existing technologies, integrated circuits are all configured on a single control motherboard, which is then fixedly installed inside the time-frequency synchronization analyzer. When the power management chip and multiple electrolytic capacitors on the integrated circuits need maintenance or are damaged and need to be replaced, the following steps are required:

[0007] ① Disassembling the entire time-frequency synchronization analyzer is a lengthy and complicated process.

[0008] ② After disassembling the time-frequency synchronization analyzer, the control motherboard also needs to be removed. Due to the influence of static electricity, this process is prone to electrostatic breakdown of chips, which can damage other chips. The disassembly process may also collide with other internal structures of the time-frequency synchronization analyzer, causing damage.

[0009] ③ When soldering and removing electrolytic capacitors or power management chips that need to be replaced from the control motherboard, the solder pads are easily damaged or detached, causing the entire control motherboard to be scrapped.

[0010] Therefore, to address the three issues mentioned above, it is necessary to disassemble the integrated circuit. The easily damaged power management chip and multiple electrolytic capacitors should be placed on a detachable mating circuit board, while other electronic components should be placed on the original control motherboard. This will reduce the risk and prevent the control motherboard from becoming unusable. At the same time, the mating circuit board should be easy to disassemble and install to facilitate the periodic replacement of electrolytic capacitors that have been used for a long time, or the replacement of damaged electrolytic capacitors or power management chips. Summary of the Invention

[0011] The purpose of this invention is to provide a portable time-frequency synchronization analyzer to solve the problems mentioned in the background art.

[0012] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0014] The analyzer body has a side forming hole on its left side. A docking circuit board is inserted into the side forming hole. After the docking circuit board is inserted into the analyzer body through the side forming hole, it will be located above the control motherboard.

[0015] The aforementioned docking circuit board is used to configure the power management chip and multiple electrolytic capacitors in the integrated circuit, and the aforementioned control motherboard is used to configure other electronic components in the integrated circuit besides the power management chip and multiple electrolytic capacitors.

[0016] The analyzer body has a support component inside for supporting the inserted docking circuit board, and the docking circuit board can move to the right along the support component; the analyzer body also has a fixed pressing component inside for the docking circuit board to extend into and fix the docking circuit board to itself, and the fixed pressing component can press down on the docking circuit board after it is fixed to itself to move it down, so that the docking circuit board and the control motherboard form an electrical connection.

[0017] A further configuration is as follows: several male electrical contacts are welded side-by-side and facing upward on the upper left side of the control motherboard, and several female electrical contacts are welded side-by-side and facing downward on the lower left side of the docking circuit board. After the fixed pressing component presses down and moves downward with the docking circuit board which is fixed to itself, the multiple male electrical contacts will form a one-to-one electrical mating with the multiple female electrical contacts, realizing the electrical connection between the control motherboard and the docking circuit board.

[0018] A further configuration is as follows: the support assembly includes two telescopic top-mounting components and a horizontal support panel; each of the two telescopic top-mounting components includes a positioning block fixed inside the analyzer body by screws, and each of the two positioning blocks has an upper access groove at its upper end, with a top-mounting spring at the bottom of each of the two upper access grooves; support pads are fixedly installed on both sides of the lower end of the support panel, and a longitudinal top-mounting contact block is fixedly installed at the lower end of each of the two support pads; the two top-mounting contact blocks extend downward into the upper access grooves of the corresponding two positioning blocks and contact the corresponding top-mounting springs, with the two top-mounting springs providing an upward force to the two top-mounting contact blocks respectively.

[0019] An anti-disengagement block is fixedly installed in the two upper access slots by a first fixing member. A follow-up block is integrally formed on the lower end of the inner side of the upper contact block. The follow-up block can collide with the anti-disengagement block to prevent the upper contact block from detaching from the upper access slot.

[0021] The right end of the travel guide block extends downward and is fixedly provided with an L-shaped built-in block by a third fixing member. The L-shaped built-in block is located below the recessed groove. The L-shaped built-in block is composed of a transverse section and a longitudinal section. The transverse section cooperates with the pressing block to form a compression cavity for the right end of the docking circuit board to extend into. When the right end of the docking circuit board extends into the compression cavity, the pressing block can press down on the docking circuit board to move downward under the drive of the travel guide block.

[0022] A further feature is provided: a transverse accompanying block extends into the right side of the pressing block, and the accompanying block and the pressing block are fixed together by a fourth fixing member. The pressing block and the accompanying block are respectively attached to the left and right inner walls of the recessed groove, allowing the pressing block to move smoothly longitudinally within the recessed groove. A compression spring is provided between the accompanying block and the upper inner wall of the travel guide block, and the compression spring provides the pressing block with the force to compress and fix the mating circuit board extending into the compression cavity.

[0023] The longitudinal section of the L-shaped built-in block can collide with the accompanying insert to prevent the pressing block from dislodging from the recessed groove.

[0024] A further setting is as follows: the lower end of the pressing block is fixedly provided with an embedded inner pressing block, and the upper right side of the docking circuit board is provided with an embedded pressing groove; after the right end of the docking circuit board extends into the extrusion cavity, it will collide with the longitudinal section of the L-shaped built-in block, and the embedded inner pressing block can extend downward into the embedded pressing groove to achieve the purpose of limiting the docking circuit board.

[0025] A further setting is that the height of the upper end face of the accompanying insert is lower than the upper end face of the lower pressure block, so that a recessed area is formed between the accompanying insert and the lower pressure block, and the compression spring extends into the recessed area.

[0026] A further configuration is as follows: a driving block is attached to the lower end face of the L-shaped built-in block, and a longitudinal insertion section is integrally formed on the upper end of the driving block. There is a gap between the longitudinal section of the L-shaped built-in block and the right end of the travel guide block. The insertion section is inserted into the gap and fixed by the third fixing member. An expandable inner cavity is formed between the insertion section and the accompanying insert. A first channel and a second channel, which are sequentially connected to the expandable inner cavity, are respectively opened on the right end of the travel guide block and inside the outer sleeve block. A first access pipe is provided on the second channel. The first access pipe extends to the upper end of the analyzer body and is provided with a first access port.

[0027] A further configuration is as follows: a lower fixing block is fixed inside the analyzer body by screws; the upper end of the lower fixing block has a lower slot located below the drive block; the drive block can extend downward into the lower slot; a third channel is provided on the right side of the lower fixing block, and the third channel communicates with the lower slot; there is always an area between the drive block and the bottom of the lower slot that is in contact with the third channel; a second access pipe is provided on the third channel, and the second access pipe extends to the upper end of the analyzer body and is provided with a second access port.

[0028] A further feature is that an oblique inlet surface is provided on the left side of the upper end of the horizontal segment.

[0029] The beneficial effects of this invention are as follows:

[0030] 1. In this invention, a docking circuit board is provided for configuring the power management chip and multiple electrolytic capacitors in the integrated circuit. The docking circuit board is separate from the control mainboard. Even if the solder pads are damaged or detached during the soldering of the power management chip and multiple electrolytic capacitors, it will not affect the control mainboard. Compared with the prior art where all integrated circuits are configured on the control mainboard, this method undoubtedly carries lower risk. If the solder pads are damaged or detached during the soldering of the power management chip and multiple electrolytic capacitors, only the docking circuit board needs to be replaced, not the control mainboard, resulting in lower costs. Furthermore, the docking circuit board facilitates installation and disassembly. It can be inserted into the analyzer body through the side-formed hole without completely disassembling the analyzer body, greatly reducing installation and disassembly time. The support component supports the inserted docking circuit board; the fixed pressing component not only secures the docking circuit board inserted into the analyzer body but also presses down on the secured docking circuit board to move it downwards, forming an electrical connection between the docking circuit board and the control mainboard. This method is highly automated and easy to install.

[0031] 2. In this invention, the electrical connection between the control motherboard and the mating circuit board is achieved by the electrical mating of the parallel male electrical contacts and female electrical contacts.

[0032] 3. In this invention, the support panel in the support assembly can support the docking circuit board. The two upper contact blocks are respectively fixed to the lower end of the support panel by the support pads. The two upper springs provide the upper contact blocks with the upper force respectively. The two upper access slots limit the two upper contact blocks respectively. The follow-up block can collide with the anti-disengagement block to prevent the upper contact blocks from disengaging from the upper access slot.

[0033] 4. In this invention, the main spring provides the downward force for the travel guide block. The pressure block is located inside the travel guide block. When the travel guide block moves downward, the pressure block will follow and move downward, thereby pressing down the mating circuit board that extends into the extrusion cavity. The mating circuit board can be pressed down and moved downward without manual force, so that the mating circuit board and the control main board can form an electrical connection.

[0034] 5. In this invention, the compression spring can contact the accompanying insert to provide the lower pressure block with the force to compress and fix the mating circuit board extending into the compression cavity; the longitudinal section of the L-shaped built-in block can collide with the accompanying insert to prevent the lower pressure block from dislodging from the recessed groove.

[0035] 6. In this invention, the embedded inner pressure block can extend into the embedded pressure groove to prevent the mating circuit board from shifting laterally; the longitudinal section of the L-shaped built-in block can collide with the right end of the mating circuit board to limit the mating circuit board.

[0036] 7. In this invention, the recessed area is used to limit the compression spring.

[0037] 8. In this invention, the plug section can extend into the gap area, and then a third fixing member is used to fix the drive block, the L-shaped built-in block and the travel guide block; gas can be filled into the expandable inner cavity through the first access port along the first access tube, the second channel and the first channel, so that the expandable inner cavity can be expanded to push the accompanying insert and the pressure block to move upward, so that the pressure block can release the pressure on the mating circuit board, which facilitates the installation and disassembly of the mating circuit board.

[0038] 9. In this invention, the drive block can extend downward into the lower slot. Gas can be injected into the bottom of the lower slot through the second access port along the second access pipe and the third channel to push the drive block, the L-shaped inner block, the outer connecting block and the travel guide block upward together. The docking circuit board is driven to move upward, thereby automatically disengaging the multiple male electrical connectors from the multiple female electrical connectors, allowing the male electrical connectors to be separated from the multiple female electrical connectors, so as to facilitate the disassembly of the docking circuit board.

[0039] 10. The surface feature introduced in this invention facilitates the insertion of the right end of the mating circuit board into the extrusion cavity. Attached Figure Description

[0050] The analyzer body 11 has a support component inside for supporting the inserted docking circuit board 22, and the docking circuit board 22 can move to the right along the support component; the analyzer body 11 has a fixed pressing component inside for the docking circuit board 22 to extend into and fix the docking circuit board 22 to itself, and the fixed pressing component can press down on the docking circuit board 22 after it is fixed to itself to move downward, so that the docking circuit board 22 and the control motherboard 15 form an electrical connection.

[0051] Among them, several male electrical contacts 23 are welded side by side and facing upward on the left side of the upper end of the control motherboard 15, and several female electrical contacts 24 are welded side by side and facing downward on the left side of the lower end of the docking circuit board 22. After the fixed pressing component is pressed down and the docking circuit board 22 is fixed to itself, the multiple male electrical contacts 23 will form a one-to-one electrical mating with the multiple female electrical contacts 24, realizing the electrical connection between the control motherboard 15 and the docking circuit board 22.

[0052] The support assembly includes two telescopic top-mounting assemblies and a transverse support panel 31. Each of the two telescopic top-mounting assemblies includes a positioning block 32 fixed inside the analyzer body 11 by screws. The upper end of each positioning block 32 is provided with an upper access groove 33, and the bottom of each upper access groove 33 is provided with a top-mounting spring 34. Support pads 35 are fixedly provided on both sides of the lower end of the support panel 31. The lower end of each support pad 35 is fixedly provided with a longitudinal top-mounting contact block 36. The two top-mounting contact blocks 36 extend downward into the upper access grooves 33 of the corresponding two positioning blocks 32 and contact the corresponding top-mounting springs 34. The two top-mounting springs 34 provide an upward force for the two top-mounting contact blocks 36 respectively.

[0053] An anti-disengagement block 372 is fixedly installed in the two upper access slots 33 by the first fixing member 371. A follow-up block 38 is integrally formed on the lower end of the inner side of the upper contact block 36. The follow-up block 38 can collide with the anti-disengagement block 372 to prevent the upper contact block 36 from disengaging from the upper access slot 33.

[0054] The fixed pressure assembly includes an upper fixing block 41 fixed inside the analyzer body 11 by screws. An outer sleeve block 42 with a hollow interior is fitted outside the upper fixing block 41. The outer sleeve block 42 can move longitudinally along the upper fixing block 41. A stroke guide block 44 is fixed inside the outer sleeve block 42 by a second fixing member 43. A downward pressure main spring 45 is provided inside the outer sleeve block 42. The upper and lower ends of the downward pressure main spring 45 are respectively connected to the upper fixing block 41 and the stroke guide block 44, allowing the stroke guide block 44 to move continuously downward. The lower end of the stroke guide block 44 has a recessed groove 441, and a downward pressure block 51 is provided in the recessed groove 441.

[0055] The right end of the travel guide block 44 extends downward and is fixedly provided with an L-shaped built-in block 47 by the third fixing member 46. The L-shaped built-in block 47 is located below the recessed groove 441. The L-shaped built-in block 47 is composed of a transverse section 471 and a longitudinal section 472. The transverse section 471 cooperates with the pressing block 51 to form a pressing cavity 48 for the right end of the docking circuit board 22 to extend into. When the right end of the docking circuit board 22 extends into the pressing cavity 48, the pressing block 51 can press down on the docking circuit board 22 to move downward under the drive of the travel guide block 44.

[0056] Among them, a transverse accompanying block 52 extends into the right side of the lower pressing block 51. The accompanying block 52 and the lower pressing block 51 are fixed together by a fourth fixing member 53. The lower pressing block 51 and the accompanying block 52 are respectively attached to the left and right inner walls of the recessed groove 441, so that the lower pressing block 51 can move longitudinally smoothly in the recessed groove 441. A compression pair spring 54 is provided between the accompanying block 52 and the upper inner wall of the stroke guide block 44. The compression pair spring 54 provides the lower pressing block 51 with the force to compress and fix the mating circuit board 22 extending into the compression cavity 48.

[0057] The longitudinal segment 472 of the L-shaped built-in block 47 can collide with the accompanying insert 52 to prevent the pressing block 51 from dislodging from the recessed groove 441.

[0058] The lower end of the lower pressure block 51 is fixedly provided with an embedded inner pressure block 551, and the upper right side of the mating circuit board 22 is provided with an embedded pressure groove 552. After the right end of the mating circuit board 22 extends into the extrusion cavity 48, it will collide with the longitudinal section 472 of the L-shaped built-in block 47. The embedded inner pressure block 551 can extend downward into the embedded pressure groove 552 to achieve the purpose of limiting the mating circuit board 22.

[0059] The height of the upper surface of the accompanying insert 52 is lower than that of the upper surface of the lower pressure block 51, so that a recessed area 56 is formed between the accompanying insert 52 and the lower pressure block 51, and the compression spring 54 extends into the recessed area 56.

[0060] The lower end of the L-shaped built-in block 47 is attached to a drive block 71. The upper end of the drive block 71 is integrally formed with a longitudinal insertion section 72. There is a gap area 73 between the longitudinal section 472 of the L-shaped built-in block 47 and the right end of the travel guide block 44. The insertion section 72 is inserted into the gap area 73 and fixed by the third fixing member 46. An expandable inner cavity 74 is formed between the insertion section 72 and the accompanying insert block 52. The right end of the travel guide block 44 and the outer sleeve block 42 are respectively provided with a first channel 75 and a second channel 76 that communicate with the expandable inner cavity 74 in sequence. A first access pipe 77 is provided on the second channel 76. The first access pipe 77 extends to the upper end of the analyzer body 11 and is provided with a first access port 78.

[0061] The analyzer body 11 is internally fixed with a lower fixing block 81 by screws. The upper end of the lower fixing block 81 has a lower slot 82 located below the drive block 71, and the drive block 71 can extend downward into the lower slot 82. A third channel 83 is provided on the right side of the lower fixing block 81, and the third channel 83 communicates with the lower slot 82. There is always an area between the drive block 71 and the bottom of the lower slot 82 that is connected to the third channel 83. A second access pipe 84 is provided on the third channel 83, and the second access pipe 84 extends to the upper end of the analyzer body 11 and is provided with a second access port 85.

[0062] Among them, an oblique inlet surface 61 is provided on the left side of the upper end of the transverse section 471.

[0063] In this embodiment, two air pumps connected to the PLC can be set up; or one air pump connected to the PLC can be set up, and then two inputs can be realized through T-tube diversion and two solenoid valves. The two inputs are respectively connected to the first access port 78 and the second access port 85 through pipelines, and the gas filling is automated based on the PLC.

[0064] The working principle of this embodiment is as follows:

[0065] ① Before installing the mating circuit board 22, gas is injected into the second access port 85. The gas will enter the bottom of the lower slot 82 through the second access pipe 84 and the third channel 83, pushing the drive block 71, the L-shaped built-in block 47, the outer connecting block 42, and the travel guide block 44 upward together until the outer connecting block 42 collides with the upper fixed block 41 for limiting. At this time, the lower end face of the extrusion cavity 48 is at the same height as the upper end face of the support panel 31. Next, gas is injected into the first access port 78. The gas will enter the expandable cavity 74 through the first access pipe 77, the second channel 76, and the first channel 75, expanding the expandable cavity 74 and pushing the accompanying insert block 52 and the lower pressing block 51 upward, thereby avoiding obstruction of the right end of the mating circuit board 22 from extending into the extrusion cavity 48.

[0066] ② When installing the docking circuit board 22, insert the docking circuit board 22 into the interior of the analyzer body 11 through the side forming hole 21. The docking circuit board 22 moves to the right along the support panel 31 until the right end of the docking circuit board 22 extends into the extrusion cavity 48 and collides with the longitudinal section 472 of the L-shaped built-in block 47 and is limited.

[0067] ③ When the gas is not charged into the first access port 78, the lower pressure block 51 will press and fix the docking circuit board 22 that extends into the pressing cavity 48 under the force of the pressing sub-spring 54. At the same time, the embedded inner pressure block 551 will extend into the embedded pressure groove 552 to prevent the docking circuit board 22 from swaying laterally.

[0068] ④ When the gas is not supplied to the second access port 85, the travel guide block 44 will move down under the force of the pressing main spring 45, and drive the pressing block 51 and the L-shaped built-in block 47 to move down synchronously. The docking circuit board 22 will be pressed down and move down, so that multiple male electrical contacts 23 and corresponding female electrical contacts 24 can be electrically connected, and the docking circuit board 22 and the control main board 15 can form an electrical connection.

[0069] ⑤ When disassembling the docking circuit board 22, gas is injected into the second access port 85 to move the docking circuit board 22 upward, allowing the multiple male electrical contacts 23 and the corresponding female electrical contacts 24 to separate; then gas is injected into the first access port 78 to move the accompanying insert 52 and the lower pressure block 51 upward, allowing the accompanying insert 52 to disengage from the embedded pressure groove 552, and then the docking circuit board 22 can be pulled out.

[0070] In this embodiment, the disassembly and installation of the docking circuit board 22 are very convenient, and the gas filling is controlled by PLC, resulting in a high degree of automation.

[0071] It should be noted that the spring force of the downward main spring 45 is greater than that of the compression secondary spring 54, and the spring force of the compression secondary spring 54 is greater than that of the upper spring 34; the support panel 31 can move upward under the force of the upper spring 34 to support the docking circuit board 22; when the docking circuit board 22 moves downward, the support panel 31 will press down synchronously, which has good flexibility.

[0072] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
