Description

Technical Field

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

[0002] In computer systems, memory modules are quite crucial. 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 installed 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, due to the lack of a stable clamping mechanism, 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 slot includes a slot body and a cover. The slot body is fixedly mounted on a circuit board and is U-shaped. The slot body has a clearance portion corresponding to the cover, and both ends of the cover are connected to the slot body via a connecting structure. The slot body, cover, and circuit board form a memory module placement area. The circuit board has several spring-loaded terminals facing the memory module placement area, which are connected to the conductive pins of the memory module. When the memory module is placed in the memory module placement area, one end of the memory module abuts against the slot body. Metal springs are fixedly mounted on both sides of the slot body. Limiting blocks are fixed to the ends of the metal springs. Limiting openings that engage with the limiting blocks are opened on both sides of the memory module. The two sides of the limiting blocks fit into the limiting openings, and the limiting blocks have pressing ends that press the memory module.

[0007] The connecting structure includes two metal pieces fixedly installed at the end of the cover. The end of each metal piece has an insert block. The card slot body has an opening that allows the metal pieces to pass through and slide up and down. A locking block is fixedly installed on the card slot body opposite the opening. The locking block has several locking grooves that can be inserted and engaged with the insert block.

[0008] The card cover has a clearance slope on the side near the limiting block.

[0009] The metal spring sheet has a deformable and bent portion.

[0010] The upper inner side of the limiting block has an arc-shaped surface.

[0011] The card slot body is fixed to the circuit board with screws.

[0012] 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

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0023] like Figure 1-9As shown, a memory card slot includes a slot body 1 and a cover 2. The slot body is fixedly mounted on a circuit board and is U-shaped. The slot body has a clearance portion corresponding to the cover, and both ends of the cover are connected to the slot body via a connecting structure. The slot body, cover, and circuit board form a memory module placement area. The circuit board has several spring terminals facing the memory module placement area that connect to the conductive pins of the memory module. When the memory module 3 is placed in the memory module placement area, one end of the memory module abuts against the slot body. Metal springs 4 are fixedly mounted on both sides of the slot body. Limiting blocks 5 are fixed to the ends of the metal springs. Limiting openings 6 are opened on both sides of the memory module to engage with the limiting blocks. The two sides of the limiting blocks fit into the limiting openings, and the limiting blocks have pressing ends 7 for pressing the memory module.

[0024] In this way, when installing a memory module, the slot body is fixedly mounted on the circuit board, and the cover is connected to the slot body through a connecting structure. The memory module is inserted into the memory module placement area, and the memory module abuts against the slot body. At the same time, the conductive pins of the memory module are aligned with the spring contacts on the circuit board. The limiting block of the metal spring contacts engages with the limiting port. Through the cooperation of the limiting block and the limiting port, the memory module is limited. The limiting block has a pressing end that presses the memory module. The pressing end presses on the memory module, and then the cover is pressed down to press the memory module firmly, so that the conductive pins of the memory module are tightly attached to the spring contacts on the circuit board, achieving a stable connection and facilitating use.

[0025] The memory module placement area is formed by the card slot body, card cover, and circuit board. The memory module abuts against the card slot body, is pressed tightly by the cover, and is limited by the limiting block, achieving all-round restriction and compression of the memory module, thus better ensuring the reliability of the memory module.

[0026] In implementation, the connection structure includes two metal pieces 8 fixedly installed at the end of the cover, the end of the metal pieces having an insert 9, the card slot body having an opening 10 that allows the metal pieces to pass through and slide up and down, and a locking block 11 fixedly installed on the card slot body opposite the opening, the locking block having several locking grooves 12 that can be inserted and engaged with the insert.

[0027] In this way, before installing the memory module, the metal plate is bent and deformed, the insert block disengages from the locking slot, the cover is moved upward to make way for the memory module, and after the memory module is in place, the cover is pressed down, the insert block moves downward and locks with the locking slot, thus pressing the memory module firmly.

[0028] Specifically, the insert has a lower inclined surface and the locking block has an upper inclined surface, which facilitates the downward movement of the insert when the cover is pressed down.

[0029] In implementation, the cover has a clearance slope 13 on the side near the limiting block. This facilitates the insertion of the memory module into the memory module placement area, creating further clearance. Simultaneously, the cover can protect the memory module from dust.

[0030] In practice, the metal spring has a deformable bending portion 14, which facilitates the bending and deformation of the metal spring.

[0031] During implementation, the upper inner side of the limiting block has an arc-shaped surface 15. This facilitates pressing down the memory module, causing the limiting block to engage with the limiting slot.

[0032] During implementation, the card slot body is fixed to the circuit board with screws, facilitating installation.

[0033] Specifically, the metal spring and metal sheet can be made of stainless steel, which is easy to bend and deform, has high elasticity, can achieve locking, is low in cost, and is easy to use. The metal spring is bonded to the card slot body, and the metal sheet is bonded to the pressure cap.

[0034] 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.
