Description

Technical Field

[0001] This utility model relates to the field of memory technology, and in particular to a memory card socket. Background Art

[0002] Memory modules are a form of random access memory (RAM) used to temporarily store data and programs for fast CPU access. Memory modules are typically mounted on the computer motherboard via slots and can be upgraded and replaced externally.

[0003] However, the memory slots currently used in laptops can only place memory modules, but cannot secure them firmly. During use, laptops are often carried around and placed in various positions. Due to the lack of a stable clamp, memory modules are prone to poor contact and loosening, which can affect the normal use of the computer system. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a memory card slot that can securely clamp the memory module, facilitate the installation and removal of the memory module, and is easy to operate.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A memory card socket includes a socket body, a positioning seat, and a locking seat;

[0007] The card slot body is fixedly mounted on the circuit board. The card slot body has a slot for inserting memory modules. Metal terminals that can contact the gold fingers of the memory modules are distributed on both sides of the slot. The metal terminals are electrically connected to the circuit board.

[0008] Two positioning blocks are fixed at the end of the positioning seat away from the card seat body. The positioning blocks are L-shaped. The end of the positioning seat near the card seat body is connected to the card seat body through a first elastic snap-fit ​​structure. Two guide rails are fixedly installed on the circuit board. The positioning seat has a guide groove that slides with the guide rails.

[0009] The upper side of the locking seat has a protruding pressure end for pressing the circuit board, and both sides of the locking seat are connected to the positioning block through a second elastic snap-fit ​​structure.

[0010] In this way, when installing the memory module, the memory module is placed on the positioning base, and two positioning blocks are used to position and limit the end of the memory module. Then, the locking seat is connected to the positioning base through a second elastic snap-fit ​​structure, pressing the end onto the memory module. Next, the positioning base is pushed, and guided by the guide rail, it moves closer to the memory slot, inserting the end of the memory module with the gold fingers into the slot of the slot body. The gold fingers contact the metal terminals, and the metal terminals electrically connect to the circuit board, achieving electrical connection between the memory module and the circuit board. The first elastic snap-fit ​​structure connects the positioning base to the slot body, completing the installation of the memory module. The positioning base provides support for the memory module, preventing the outer end from being suspended in the air. The locking seat limits and presses the end of the memory module, ensuring a stable installation within the slot body, improving installation stability and reliability.

[0011] The positioning seat has a clearance opening.

[0012] The positioning base has positioning blocks fixed on both sides. The positioning blocks are cylindrical and engage with the openings on the side of the memory module.

[0013] The first elastic snap-fit ​​structure includes end blocks fixedly installed at both ends of the positioning seat. A first metal spring is fixed to the end of the end block, a first snap-fit ​​block is fixed to the inner side of the first metal spring, and a second snap-fit ​​block is fixed to both sides of the positioning seat body. The first snap-fit ​​block engages with the second snap-fit ​​block.

[0014] The first card block has a first inclined surface at the end near the card holder body.

[0015] The second elastic snap-fit ​​structure includes a second metal spring sheet, the second metal spring sheet is fixed with a third snap-fit ​​block, and the positioning block has a limiting groove for limiting the second metal spring sheet.

[0016] The third card block has a second inclined surface on the side near the positioning block.

[0017] Both the first and second metal springs have outwardly protruding curved portions.

[0018] In summary, this memory card slot has the advantages of securely holding the memory module in place, facilitating the installation and removal of the memory module, and being easy to operate. Attached Figure Description

[0025] like Figure 1-5 As shown, a memory card slot includes a slot body 1, a positioning seat 2, and a locking seat 3;

[0026] The card slot body is fixedly mounted on the circuit board. The card slot body has a slot for inserting memory module 4. Metal terminals that can contact the gold fingers of the memory module are distributed on both sides of the slot. The metal terminals are electrically connected to the circuit board.

[0027] Two positioning blocks 5 are fixed at the end of the positioning seat away from the card seat body. The positioning blocks are L-shaped. The end of the positioning seat near the card seat body is connected to the card seat body through a first elastic snap-fit ​​structure. Two guide rails 6 are fixedly installed on the circuit board. The positioning seat has a guide groove that slides with the guide rails.

[0028] The upper side of the locking seat is provided with a pressure end 7 for pressing the circuit board, and both sides of the locking seat are connected to the positioning block through a second elastic snap-fit ​​structure.

[0029] In this way, when installing the memory module, the memory module is placed on the positioning base, and two positioning blocks are used to position and limit the end of the memory module. Then, the locking seat is connected to the positioning base through a second elastic snap-fit ​​structure, pressing the end onto the memory module. Next, the positioning base is pushed, and guided by the guide rail, it moves closer to the memory slot, inserting the end of the memory module with the gold fingers into the slot of the slot body. The gold fingers contact the metal terminals, and the metal terminals electrically connect to the circuit board, achieving electrical connection between the memory module and the circuit board. The first elastic snap-fit ​​structure connects the positioning base to the slot body, completing the installation of the memory module. The positioning base provides support for the memory module, preventing the outer end from being suspended in the air. The locking seat limits and presses the end of the memory module, ensuring a stable installation within the slot body, improving installation stability and reliability.

[0030] In practice, the positioning base is provided with a clearance opening 8 to prevent the positioning base from making large-area contact with the memory module and affecting the heat dissipation of the memory module.

[0031] During implementation, positioning blocks 9 are fixed on both sides of the positioning base. The positioning blocks are cylindrical and engage with the opening 10 on the side of the memory module. This facilitates further positioning of the memory module.

[0032] In implementation, the first elastic snap-fit ​​structure includes end blocks 11 fixedly installed at both ends of the positioning seat. A first metal spring 12 is fixed to each end block, and a first locking block 13 is fixed to the inner side of the first metal spring. Second locking blocks 14 are fixed to both sides of the positioning seat body, and the first locking blocks engage with the second locking blocks. Rapid assembly is achieved by engaging the first locking block of the first metal spring with the second locking block of the positioning seat body.

[0033] In practice, the first card block has a first inclined surface at the end near the card holder body. When the positioning seat is moved, the first inclined surface can better guide the movement.

[0034] In implementation, the second elastic snap-fit ​​structure includes a second metal spring 15, the second metal spring being fixed with a third snap-fit ​​block 16, and the positioning block having a limiting groove for limiting the second metal spring component. This facilitates the quick assembly of the locking seat and the positioning seat.

[0035] In practice, the third locking block has a second inclined surface on the side near the positioning block. This second inclined surface acts as a guide during the assembly of the locking seat and the positioning seat.

[0036] In practice, both the first and second metal springs have outwardly protruding curved portions, facilitating bending and deformation of the metal springs.

[0037] Specifically, the first and second metal springs are made of stainless steel sheets, which are easy to bend and deform, have great elasticity, can achieve locking, are low in cost, easy to use, and can be connected by adhesive, making them easy to assemble.

[0038] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
