Description

Technical Field

[0001] This application relates to the field of memory insertion and removal fixtures, and more particularly to a memory insertion and removal fixture that is easy to disassemble. Background Technology

[0002] The existing memory insertion and removal fixtures are too large to meet the needs of the current test motherboards. Furthermore, the current method of manually pressing the memory modules can easily lead to uneven stress on the server motherboard. Repeated insertion and removal operations may damage the server motherboard and cause significant economic losses.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Summary of the Invention

[0004] This application provides a memory insertion and removal fixture that is easy to disassemble, in order to solve the above-mentioned problems.

[0005] In a first aspect, this application provides a memory insertion and removal fixture that is easy to disassemble, including an auxiliary memory removal fixture and an auxiliary memory insertion fixture. The auxiliary memory removal fixture includes a first pressing block and a first latch, and the inner surface of the first pressing block is movably connected to the first latch via a first rotating rod. The rotating rod mainly performs the function of rotating and fixing the latch in the entire fixture. The auxiliary memory insertion fixture includes a second pressing block and a second latch, and the inner surface of the second pressing block is movably connected to the second latch via the first rotating rod.

[0006] Preferably, pre-drilled holes are provided at the connection points of the second pressure block and the first rotating rod, and at the connection points of the first pressure block and the first rotating rod. The middle of the first and second handles is hollowed out, and the handle position is rounded to avoid discomfort to the operator caused by sharp edges and optimize the user experience. The hollow size of the first handle is 30mm, and the hollow size of the second handle is 130*1215mm, which can comfortably accommodate two fingers, making it easy to grip and operate. This conforms to ergonomic design and improves the convenience and comfort of operation.

[0007] Preferably, a first slider is inserted into the right side of the first handle to achieve linkage, and a lifting piece is connected to the right side of the first slider by a second screw. A positioning block is fixedly connected to the right side of both the first handle and the right side of the first slider.

[0008] Preferably, the left side of the first slider and the upper end of the inner surface of the lifting piece are provided with positioning grooves that are compatible with the positioning block to reduce assembly deviation. The lifting piece has four slots with a center distance of 7.2mm between adjacent slots, which matches the spacing of the memory slots on the server motherboard, ensuring installation accuracy. Each slot is 5.7mm wide, and the maximum thickness of the memory module is about 3.5mm, leaving enough space to prevent the memory module from being damaged by scratching or bumping against the components on the PCB board during use. The structure is safe and reliable.

[0009] Preferably, the front and rear sides of the outer surface of the first pressure block are connected to the first fixing plate by the first screw, the inner surface of the first fixing plate is snapped with the first snap, the inner side of the first snap is fixedly connected with the first spring, and the end of the first spring is fixedly connected to the surface of the first pressure block.

[0010] Preferably, the front and rear sides of the outer surface of the second pressure block are connected to a second fixing plate by a third screw. The inner surface of the second fixing plate is snapped with a second snap, and the inner side of the second snap is fixedly connected with a second spring, and the end of the second spring is fixedly connected to the surface of the second pressure block.

[0011] Preferably, both the first and second snaps are hollow structures. A protruding rod is fixedly connected to the surface of the first pressure block and the inner side of the first spring, and to the surface of the second pressure block and the inner side of the second spring. This rod can limit the movement of the first and second snaps during pressing, preventing them from detaching from the surfaces of the first and second pressure blocks. Furthermore, both the first and second snaps have locking positions at their bottoms, which can engage with grooves cut into the side walls of the temperature chamber structure to prevent the fixture from shifting left or right during use, achieving precise alignment. This fixing method is more flexible in disassembly and assembly, and easier to maintain and replace compared to the traditional method of using screws to lock the entire fixture to the fixed base plate.

[0012] Preferably, the bottom of the second pressure block is connected to a guide plate by a fourth screw, and both ends of the top of the guide plate are fixedly connected to protruding rods, and the bottom of the second pressure block is provided with a slot that matches the protruding rods.

[0013] Preferably, the guide plate has 4 slots, with a center-to-center distance of 18.13mm between each slot, which is compatible with the spacing of memory slots on the server motherboard. The slot width is 11.16mm, and the design retains a safe distance, which can both meet the guiding function and prevent collisions with electrical components on the memory module.

[0014] Preferably, the inner surface of the second handle is connected to a pressure plate by a third screw. The upper end of the inner surface of the pressure plate has two fixing holes. By adjusting the installation position of the third screw, it can be adapted to memory modules of different heights, increasing the versatility of the fixture. The bottom of the pressure plate is movably connected to a round block by a second rotating rod, which can play a buffering role during the pressing process, absorbing part of the impact force and avoiding damage to the memory module. A reserved groove is provided at the connection between the pressure plate and the round block. There are four round blocks, and the center distance between each round block is aligned with the center distance between the memory modules.

The inner surface of the second latch 11 is connected to a third screw 15. The lower pressure plate 20 has two fixing holes on the upper end of its inner surface. By adjusting the installation position of the third screw 15, it can be adapted to memory modules of different heights, increasing the versatility of the fixture. The bottom of the lower pressure plate 20 is movably connected to a round block 19 through the second rotating rod 18, which can play a buffering role during the pressing process, absorbing part of the impact force and avoiding damage to the memory module. A reserved groove is provided at the connection between the lower pressure plate 20 and the round block 19. There are four round blocks 19, and the center spacing of each round block 19 is aligned with the center spacing of the memory module.

[0039] The working principle of this application is as follows:

[0040] The auxiliary memory removal fixture is based on the principle of a crank-slider mechanism. It drives the intermediate transmission component (first slider 8) through a rotation input (first latch 1), which is ultimately converted into a linear output (linear displacement of the lifting plate 6). Specifically, when using the fixture, the fixture needs to be aligned and assembled onto the memory module test temperature cavity structure by pressing the first snap buttons 5 on both sides. After assembly, the bottom of the lifting plate 6 will be inserted into the groove on the side of the memory module to ensure correct connection with the memory module. By manually flipping the first latch 1 outward, the first latch 1 drives the first slider 8 to move upward, and the lifting plate 6 moves accordingly to remove the memory module from the motherboard slot. Four memory modules can be removed at a time, which improves the operating efficiency.

[0041] The auxiliary memory insertion fixture is based on the lever principle and torque conversion. Using the first rotating rod 12 as a fixed fulcrum, when the second latch 11 rotates inward, it presses against the upper edge of the memory module, converting the inward rotational force into a downward pressure acting vertically on the memory module. Specifically, when using the fixture, the fixture is aligned and assembled onto the memory module testing chamber structure by pressing the second snaps 16 on both sides. The slots on the guide plate 17 are aligned with the memory slot slots on the motherboard. The memory modules are then placed into the slots one by one, aligned with the grooves on the guide plate 17, and the second latch 11 is flipped inward. This causes the lower pressure plate 20 to rotate downward through the first rotating rod 12. The lower pressure plate 20 applies pressure to the memory module, pressing it into the motherboard slot. The round block 19 on the lower pressure plate 20 acts as a buffer, preventing damage to the memory module or motherboard due to excessive force. This fixture can insert four memory modules at a time, significantly improving efficiency.
