Description

Technical Field

[0001] This utility model relates to the field of interface board manufacturing technology, and in particular to a test interface board assembly and aging test equipment. Background Technology

[0002] Interface board aging test is an important step to ensure the long-term stable operation of electronic equipment. Aging test usually includes testing the interface board under extreme conditions for a long time to verify its reliability and stability within its design life.

[0003] Multiple interface boards are placed in alternating high and low temperature environments and subjected to aging tests through operation over a certain period of time. For example, the existing Chinese patent announcement number "CN217212814U" discloses an integrated aging cabinet for AC base plates and interface boards, comprising a main structure including a cabinet. The cabinet contains product aging areas for front and rear placement and a load mounting area. The load mounting area has multiple parallel and equidistantly placed vertical load mounting strips. The overall free-flowing operating space overcomes the obstruction limitations of conventional designs with partitions, eliminating visual obstructions. The interface boards are positioned on the outer side, allowing for free and open space for plugging and unplugging connecting cables. This greatly facilitates the placement and removal of aging products and avoids damage to the outer shell during product insertion and removal, thus significantly improving aging efficiency. A single cabinet can age up to 480 products at once and can intelligently monitor the aging status of each product in real time, automatically collecting and remotely uploading various aging data. It is compatible with various charging and discharging protocols on the market, offering comprehensive functions, high cost-effectiveness, convenient operation, and a beautiful and practical design.

[0004] In actual operation, a cooling fan is installed to exhaust the high-temperature air inside the cabinet in order to accelerate the cooling efficiency inside the cabinet. However, there is no dust filtration measure on the outside of the cooling fan. After long-term use, dust accumulates inside the cooling fan, and the dust may fall onto the interface board, affecting its practicality. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of dust filtration measures around the cooling fan, and to propose a test interface board assembly and aging test equipment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a test interface board assembly and aging test equipment, including a test box, an end cover for closing the test chamber opening on the end face of the test box, a mounting frame located inside the test chamber, a wiring unit for connecting the interface board on the end face of the mounting frame, and a fixing component for fixing the interface board.

[0008] The testing chamber is also equipped with a heating unit and a cooling unit. The cooling unit includes an air supply component, and a filter and a closing component are located around the air supply component. The filter and the closing component are used to filter dust and close the air supply port, respectively.

[0009] Furthermore, the fixing component includes a fixing frame, the top two sides of which are rotatably connected to the detection box via a rotating shaft and a torsion spring, and the bottom of the fixing frame is able to abut against the interface plate.

[0010] Furthermore, a first positioning glass bead is embedded on the inner side of the detection box, and the fixing frame is rotated to make it abut against the telescopic column end of the first positioning glass bead.

[0011] Furthermore, the side of the testing box is fixedly connected to the air supply component inside the air supply port, and the side of the testing box is fixedly connected to the mounting base outside the air supply port. The mounting base is provided with an extension and an elastic element inside.

[0012] Furthermore, the inner bottom of the mounting base extends towards the midpoint to form the extension portion, and the filter element is provided between the extension portion and the elastic element. The elastic element slides and abuts against the mounting base to cooperate with the extension portion to fix the filter element.

[0013] Furthermore, the closure is rotatably connected to the periphery of the mounting base. The closure has a U-shaped structure and a through hole at one end of its side facing away from the rotating shaft. A second positioning glass bead is embedded in the side of the mounting base, and the telescopic column end of the second positioning glass bead engages with the through hole.

[0014] The present invention provides a test interface board assembly and an aging test device, which have the following advantages: The present invention is equipped with a fixing component for fixing the interface board and a cooling unit for accelerating the cooling of the inside of the chamber. The telescopic column end of the first positioning glass bead abuts against the bottom of the fixing frame, which can fix the interface board after the fixing frame is unlocked, facilitating the loading and unloading of the interface board. The filter can be disassembled and replaced by removing the elastic component. The filter can block external dust and prevent dust from adhering to the exhaust fan. A closing component is also provided to effectively prevent the high-temperature air inside the chamber from being discharged by closing the air outlet. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-4 A test interface board assembly and aging test equipment includes a test box 1, an end cover 2 for closing the opening of a test chamber 11 on the end face of the test box 1, a mounting frame 3 located inside the test chamber 11, a wiring unit 4 for connecting the interface board on the end face of the mounting frame 3, and a fixing component 5 for fixing the interface board.

[0022] The detection box 1 is also equipped with a heating unit and a cooling unit 6. The cooling unit 6 includes an air supply component 61, and a filter component 62 and a closing component 63 are provided around the air supply component 61. The filter component 62 and the closing component 63 are used to filter dust and close the air supply port, respectively.

[0023] In some embodiments, the wiring unit 4 is connected to an external power supply, and the interface board is connected to the wiring unit 4 to perform aging tests in a high-temperature or low-temperature environment for a certain period of time.

[0024] Among them, the air supply component 61 is an exhaust fan, which accelerates the air flow speed inside the detection box 1 by suction or exhaust, thereby achieving the effect of cooling. The filter component 62 is a filter screen, which is used to block external dust. Furthermore, by closing the air supply port by the closing component 63, the speed at which high-temperature air inside the box leaks out can be effectively prevented or slowed down.

[0025] Furthermore, the fixing component 5 includes a fixing frame 51, the top two sides of which are rotatably connected to the detection box 1 via a rotating shaft and a torsion spring 52, and the bottom of the fixing frame 51 can abut against the interface plate.

[0026] Furthermore, a first positioning glass bead 12 is embedded on the inner side of the detection box 1, and the fixing frame 51 is rotated to make it abut against the telescopic column end of the first positioning glass bead 12.

[0027] It is worth mentioning that the fixing frame 51 has a rectangular structure. The two ends of the torsion spring 52 are fixedly connected to the inner wall of the test box 1 and the side of the fixing frame 51, respectively. Under the action of the torsion spring 52, the bottom of the fixing frame 51 abuts against the interface plate to prevent the interface plate from sliding unexpectedly during the test.

[0028] Furthermore, after pressing the telescopic column end of the first positioning glass bead 12 to retract it, the fixing frame 51 is rotated. After the telescopic column end of the first positioning glass bead 12 is reset, it abuts against the fixing frame 51 to fix the fixing frame 51, which facilitates the loading and unloading of the interface plate.

[0029] More specifically, the side of the test box 1 is fixedly connected to the air supply component 61 inside the air supply port, and the side of the test box 1 is fixedly connected to the mounting base 7 outside the air supply port. The mounting base 7 is provided with an extension 71 and an elastic component 72 inside.

[0030] In general, the inner bottom of the mounting base 7 extends towards the midpoint to form the extension portion 71. The filter element 62 is provided between the extension portion 71 and the elastic member 72. The elastic member 72 slides and abuts against the mounting base 7 to cooperate with the extension portion 71 to fix the filter element 62.

[0031] It should be added that the elastic element 72 is preferably made of materials such as rubber or plastic, the mounting base 7 has a rectangular structure, and the diameter of the elastic element 72 is slightly larger than the opening size of the mounting base 7, so as to use its elasticity to fix it in the mounting base 7 by pressing and friction.

[0032] Finally, the mounting base 7 is rotatably connected to the closure member 63. The closure member 63 has a U-shaped structure and a through hole 631 is provided at one end of its side facing away from the rotating shaft. The side of the mounting base 7 is fitted with a second positioning glass bead 73, and the telescopic column end of the second positioning glass bead 73 engages with the through hole 631.

[0033] Furthermore, a sealing gasket is provided on the inner wall of the closure 63, and the sealing element fits against the top surface of the mounting base 7, further improving the sealing performance when the air outlet is closed.

[0034] Working method: When working, press the telescopic column end of the first positioning glass bead 12 to make it retract, then rotate the fixing frame 51. After the telescopic column end of the first positioning glass bead 12 is reset, it abuts against the fixing frame 51 to fix the fixing frame 51, which facilitates the feeding of the interface plate. The interface plate is connected to the wiring unit 4. Conversely, after feeding, the fixing frame 51 can be used to abut and fix the interface plate.

[0035] Then, the end cap 2 is closed and the temperature inside the test chamber 1 is increased by the heating unit. Of course, the closing member 63 is also closed by engaging the through hole 631 with the telescopic column end of the second positioning glass bead 73 to prevent air from being discharged along the air outlet. Conversely, after the closing member 63 is opened, the air supply member 61 can accelerate the air flow speed inside the test chamber 1.

[0036] Finally, after unlocking the elastic element 72, the filter element 62 can be directly disassembled, cleaned, and replaced.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
