Description
Technical Field
[0001] The present application relates to the field of industrial testing technology, and in particular to a buckle opening force testing device. Background Art
[0002] In computer hardware, the memory slot is a key component used to install memory sticks (RAM). The memory slot is usually equipped with a clip that is used to fix the memory stick to ensure good contact between the memory stick and the memory slot. The design and operation of the clip are crucial to the performance and stability of the memory stick. In the process of designing and manufacturing the clip, the clip opening force (i.e., the force required to open the clip) is an important parameter to set. The clip opening force directly affects the convenience of the user to install the memory stick and the stability of the memory stick. However, there is no test device that can measure the clip opening force. Utility Model Content
[0003] Based on this, it is necessary to provide a buckle opening force testing device to measure the opening force of the buckle.
[0004] A buckle opening force testing device, comprising:
[0005] An installation assembly comprising a rotatably connected fixing member and a test board, wherein the test board is used to install a memory slot member equipped with a clip, and the test board is configured to rotate relative to the fixing member to adjust the relative position of the clip and the fixing member;
[0006] The force measuring assembly includes a mechanical testing machine and a pressure sensor, wherein the pressure sensor is connected to the output end of the mechanical testing machine, and the output end of the mechanical testing machine is used to abut against the terminal of the buckle so that the pressure sensor measures the force required to open the buckle.
[0007] In the aforementioned buckle-opening force testing device, the test board of the mounting assembly is used to mount a memory slot component equipped with a buckle, while the fixing member and the test board are rotatably connected. Rotating the test board relative to the fixing member adjusts the relative position of the buckle and the fixing member, thereby adjusting the buckle's testing angle. By providing a force-measuring assembly, the output end of the force-measuring assembly's mechanical testing machine can apply pressure to the buckle's terminals, thereby opening the buckle. A pressure sensor is connected to the output end of the mechanical testing machine. When the output end of the mechanical testing machine applies pressure to the buckle's terminals, the pressure sensor measures the force required to open the buckle, thereby accurately measuring the buckle's opening force.
[0008] In one embodiment, the mounting assembly further includes a limiting member, and the limiting member is used to limit the rotation trajectory of the test plate.
[0009] By setting the limiting member, the rotation track of the test board is restricted, thereby restricting the movement track of the memory slot member and the buckle installed on the test board.
[0010] In one embodiment, the limiting member includes an arc-shaped sliding groove, a sliding rod is provided on the test plate, part of the sliding rod extends into the sliding groove, and the test plate is configured to rotate relative to the fixing member to drive the sliding rod to slide in the sliding groove.
[0011] By setting the limiting part as an arc-shaped slide groove, a sliding rod is installed on the test plate, and one end of the sliding rod is extended into the slide groove. When the test plate rotates relative to the fixed part, the sliding rod slides in the slide groove, thereby achieving the effect of limiting the rotation trajectory of the test plate.
[0012] In one embodiment, the mounting assembly further includes a positioning member, and the positioning member is used to limit the relative movement between the fixing member and the test plate after the test plate is rotated to a preset position.
[0013] By setting the positioning piece, when the test plate rotates to a preset position relative to the fixing piece, the fixing piece limits the relative movement between the fixing piece and the test plate, thereby limiting the movement of the test plate, making it easier to carry out the next force measurement process.
[0014] In one embodiment, a plurality of positioning members are provided, and the plurality of positioning members are arranged along the extension direction of the sliding groove.
[0015] A plurality of positioning members are arranged along the extension direction of the slide groove, and the relative positions of the test plate and the fixing member restricted by each positioning member are different. By using a plurality of positioning members, a plurality of preset positions can be restricted, which facilitates the force measurement process at a plurality of preset positions.
[0016] In one embodiment, the force measuring assembly further includes a position sensor, and the position sensor is used to detect the relative position between the output ends of the mechanical testing machine and the terminals of the buckle.
[0017] By setting a position sensor, before the output end of the measuring mechanical testing machine presses down the terminal of the buckle, the position sensor measures the relative position between the output end of the mechanical testing machine and the terminals of the buckle, so that the output end of the measuring mechanical testing machine can be moved to the vicinity of the terminals of the buckle, making it easier to press down the terminals of the buckle.
[0018] In one embodiment, the mechanical testing machine includes a pressing head, which is connected to the output end of the mechanical testing machine through a screw, and the pressing head is used to press the terminal of the buckle.
[0019] By providing a pressing head, the pressing head is connected to the output end of the mechanical testing machine through a screw rod. The pressing head can abut against the terminal of the buckle, thereby completing the process of opening the buckle.
[0020] In one embodiment, a limiting groove is provided on the fixing member, and a partial area of the test board is engaged with the limiting groove.
[0021] By setting a limit groove on the fixing part, a part of the test plate is clamped in the limit groove, thereby limiting the relative position between the fixing part and the test plate, so as to further limit the relative movement of the fixing part and the test plate during the force measurement process.
[0022] In one embodiment, the mechanical testing machine includes a display screen, and the display screen is used to display a pressure change curve when the output end of the mechanical testing machine contacts the terminal of the buckle.
[0023] By setting up a display screen, during the force measurement process, the display screen can show a pressure change curve when the output end of the mechanical testing machine contacts the terminal of the buckle, thereby making it easy to know the opening and closing force of the buckle through the pressure change curve.
[0024] In one embodiment, the mechanical testing machine is a triaxial insertion and extraction force testing machine.
[0025] A three-axis plugging force tester will be used. It not only has high measurement accuracy, but also the output end of the three-axis plugging force tester can move in multiple directions, which is convenient for pressing and opening the terminals of the buckle.

The following description sets forth many specific details to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways than those described herein, and those skilled in the art can make similar improvements without violating the scope of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.
[0035] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing this application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on this application.
[0036] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.
[0037] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.
[0038] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium. Furthermore, when a first feature is described as being "above," "above," or "above" a second feature, it may mean that the first feature is directly above or diagonally above the second feature, or simply means that the first feature is at a higher level than the second feature. When a first feature is described as being "below," "below," or "below" a second feature, it may mean that the first feature is directly below or diagonally below the second feature, or simply means that the first feature is at a lower level than the second feature.
[0039] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.
[0040] In computer hardware, the memory slot assembly is a critical component used to install memory modules (RAM). The memory slot assembly is typically equipped with a pair of latches that secure the memory module and ensure proper contact with the slot. The design and operation of the latches are crucial to the performance and stability of the memory module.
[0041] The design and manufacturing of memory slot latches can present challenges. For example, the latch can be damaged due to material fatigue or improper handling. Furthermore, the latch's opening force (the force required to open the latch) is a crucial parameter, directly impacting both the user's ease of installation and the stability of the memory module.
[0042] Accurately measuring the opening force of memory slot latches is extremely important. However, existing measurement methods may not provide accurate and consistent results, or require complex equipment and operations.
[0043] To this end, the present application provides a buckle opening force testing device, such as Figure 1As shown, the buckle opening force testing device includes a mounting assembly and a force measuring assembly, the mounting assembly includes a rotatably connected fixing member 100 and a test board 200, the test board 200 is used to install a memory slot assembly 600 equipped with a buckle, and the test board 200 is configured to rotate relative to the fixing member 100 to adjust the relative position of the buckle and the fixing member 100; the force measuring assembly includes a mechanical testing machine and a pressure sensor 300, the pressure sensor 300 is connected to the output end of the mechanical testing machine, and the output end of the mechanical testing machine is used to abut against the terminal of the buckle so that the pressure sensor 300 measures the force required to open the buckle.
[0044] In the aforementioned buckle opening force testing device, the test board 200 of the mounting assembly is used to mount a memory slot assembly 600 equipped with a buckle, while the fixing member 100 and the test board 200 are rotatably connected. Rotating the test board 200 relative to the fixing member 100 adjusts the relative position of the buckle and the fixing member 100, thereby adjusting the buckle test angle. By providing a force measuring assembly, the output end of the force measuring assembly's mechanical testing machine can apply pressure to the buckle's terminal, thereby opening the buckle. A pressure sensor 300 is connected to the output end of the mechanical testing machine. When the output end of the mechanical testing machine applies pressure to the buckle's terminal, the pressure sensor 300 can measure the force required to open the buckle, thereby accurately measuring the buckle's opening force.
[0045] It should be noted that a mechanical testing machine is a tool for measuring the mechanical properties of an object. It is primarily used in areas such as material mechanical performance testing, manufacturing quality control, and scientific research. A mechanical testing machine applies force and measures deformation and other parameters to examine the performance and behavior of a material under different loads.
[0046] In some embodiments, the mechanical testing machine is a triaxial insertion and extraction force testing machine. A triaxial insertion and extraction force testing machine is selected because it not only has high measurement accuracy but also has an output end that can move in multiple directions, facilitating the pressing and opening of the terminal.
[0047] In some embodiments, as Figure 1 As shown, the mounting assembly further includes a limiter 400, which is used to limit the rotation trajectory of the test board 200. By setting the limiter 400, the rotation trajectory of the test board 200 is limited, which also limits the movement trajectory of the memory slot assembly 600 and the buckle installed on the test board 200.
[0048] Specifically, if Figure 1As shown, the limiting member 400 includes an arcuate slot, a slide rod is provided on the test board 200, and a portion of the slide rod extends into the slot. The test board 200 is configured to rotate relative to the fixed member 100 to drive the slide rod to slide within the slot. By configuring the limiting member 400 as an arcuate slot, installing the slide rod on the test board 200, and extending one end of the slide rod into the slot, when the test board 200 rotates relative to the fixed member 100, the slide rod slides within the slot, thereby limiting the rotational trajectory of the test board 200.
[0049] In some embodiments, the mounting assembly further includes a positioning member, which is used to limit relative movement between the fixture 100 and the test plate 200 after the test plate 200 rotates to a preset position. By providing the positioning member, when the test plate 200 rotates to the preset position relative to the fixture 100, the fixture 100 limits the relative movement between the fixture 100 and the test plate 200, facilitating the next force measurement process.
[0050] In some embodiments, multiple positioning members are provided, and the multiple positioning members are arranged along the extension direction of the chute. The multiple positioning members are arranged along the extension direction of the chute, and each positioning member restricts a different relative position of the test plate 200 and the fixing member 100. Utilizing multiple positioning members, the test plate 200 and the fixing member 100 can be restricted to multiple different relative positions, facilitating force measurement at different positions.
[0051] In some embodiments, the force measuring assembly further includes a position sensor configured to detect the relative position between the output terminals of the mechanical testing machine and the terminals of the buckle. By providing the position sensor, the position sensor measures the relative position between the output terminals of the mechanical testing machine and the terminals of the buckle before the output terminals of the mechanical testing machine are pressed against the terminals of the buckle, thereby enabling the output terminals of the mechanical testing machine to be moved to the vicinity of the terminals of the buckle, facilitating the downward pressure of the terminals of the buckle.
[0052] In some embodiments, the mechanical testing machine includes a pressing head 500, which is connected to the output end of the mechanical testing machine via a screw. The pressing head 500 is used to press the terminal of the buckle. By providing the pressing head 500, which is connected to the output end of the mechanical testing machine via a screw, the pressing head 500 can abut against the terminal of the buckle, thereby completing the process of opening the buckle.
[0053] Specifically, the abutting portion of the pressing head 500 is adapted to the shape of the terminal of the buckle.
[0054] In some embodiments, a limiting slot is provided on the fixture 100, and a portion of the test plate 200 is engaged with the limiting slot. By providing the limiting slot on the fixture 100 and engaging a portion of the test plate 200 with the limiting slot, the relative position between the fixture 100 and the test plate 200 is limited, thereby further restricting the relative movement of the fixture 100 and the test plate 200 during the force measurement process.
[0055] In some embodiments, the mechanical testing machine includes a display screen for displaying a graph of pressure changes when the output end of the mechanical testing machine contacts the terminals of the buckle. By providing a display screen, during the force measurement process, the display screen can display a graph of pressure changes when the output end of the mechanical testing machine contacts the terminals of the buckle, thereby facilitating the determination of the buckle's opening and closing force from the pressure change graph.
[0056] In summary, the buckle opening force testing device of the present application has the following beneficial effects:
[0057] 1. Dedicated test board 200 and fixture 100: can stably fix the memory slot 600 to prevent any unnecessary movement during the test;
[0058] 2. Pressure sensor 300 and pressure head 500: The design of the pressure sensor 300 and pressure head 500 enables the device to accurately measure the opening force of the memory slot component 600 buckle;
[0059] 3. Real-time data analysis and display: The device can collect and analyze data in real time, and then display the results on the display screen, so that users can immediately understand the test results.
[0060] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0061] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
