Description

[0001] This application claims priority to prior application number: 202420417733.4, prior application date: 2024.3.5, and utility model name: Electronic card fastening device. Technical Field

[0002] The utility model relates to a buckling device for an electronic card, in particular to a buckling structure for an electronic card (such as a solid state hard disk) which has a simple structure, is convenient to assemble and to operate. Background Art

[0003] The traditional solid state drive (SSD) standard is the mSATA standard, but it is limited by the number of flash memory chips that can be placed on the circuit board (PCB), which limits its overall capacity. Therefore, the newer NGFF (Next Generation Form Factor; also known as M.2) standard suitable for solid state drives has emerged. Since the M.2 standard can place flash memory chips on both sides of the circuit board, it has a smaller size and higher capacity than the traditional mSATA standard, and it also has the advantages of reducing costs.

[0004] Generally, M.2 standard SSDs have various lengths to choose from, and computer motherboards are also designed to share SSDs of various lengths. In response to the need to fix SSDs of different lengths, screws and studs are currently mostly used to lock M.2 standard SSDs on computer motherboards; however, the combination of screws and studs is not only very inconvenient in assembly and disassembly, but also requires the embedding of studs on the computer motherboard for screw locking, which leads to increased costs.

[0005] In an existing assembly buckle structure, it includes: a bearing portion, a pivot portion, a protruding portion and a pressing portion; the bearing portion has a bearing surface and a back surface opposite to each other. The pivot portion and the protruding portion protrude from the back surface of the bearing portion and the bearing surface of the bearing portion, respectively, and extend along the axial direction of the pivot portion. The pressing portion protrudes from one side of the protruding portion and extends along the radial direction of the pivot portion, so that a locking groove is formed between the pressing portion and the bearing portion, and a release notch is provided next to the locking groove and is not covered by the pressing portion.

[0006] When the above structure is used, the assembly clip can insert the pivot part into the corresponding assembly hole on the computer motherboard according to the specifications of the solid state drive, and a tool (such as a flat-blade screwdriver) is inserted into the preset operating groove on the protruding part to rotate the protruding part of the assembly clip so that the locking groove and the release notch located on the two opposite sides can be respectively oriented towards the solid state drive to form different states such as fixed or released; however, in actual application, this device must be operated with a specific tool (a flat-blade screwdriver), and the operation method of rotating the protruding part is also more troublesome, and the effect of easy operation cannot be achieved.

[0007] In addition, another locking device combination has a main body component arranged on the circuit board, and at least one clamping member is accommodated inside the main body component. A clamping portion is recessed on one side of the clamping member, and a spring sheet or elastic member that can push against the clamping member is also arranged inside the main body component, so that the clamping member can maintain a stretchable and tilting elasticity.

[0008] In actual application, the edge of the electronic card (SSD) can be directly pressed down from the top of the card holder, so that the card holder produces elastic compression and skew movement, and the clamping part is clamped on the side of the notch at the edge of the electronic card (SSD) to form an easy-to-operate and stable positioning; however, the composition of the above-mentioned structure is relatively complex and difficult to assemble, which does not meet the economic benefits of low-priced components.

[0009] There is also an M.2 card quick disassembly and assembly buckle, which has a fixed seat and a sliding block, and the fixed seat is provided with obliquely extending sliding grooves on both sides, and the sliding block is provided with outwardly protruding guide columns on both sides, and the guide columns can be extended into the sliding groove to form a sliding guide, and a spring is provided between the fixed seat and the sliding block; when the sliding block is subjected to force, the guide column slides in the sliding groove, and the sliding block can simultaneously generate a backward horizontal movement and an upward movement above the fixed seat to provide space for an M.2 card to be embedded downward; and when the sliding block is not subjected to force, the elastic force of the spring can be used to restore the sliding block to the original initial (positioning) position of the buckle of the M.2 card.

[0010] The above structure still needs to rely on the spring component to drive the sliding block to return to the movement. The overall components are relatively large and the assembly is complicated, which cannot achieve the actual cost reduction effect. In addition, when in use, the sliding groove will simultaneously derive a vertical component force required for the lifting movement from the horizontal force that drives the sliding block to move laterally, and cause severe friction between the guide column and the sliding groove. In this way, it is necessary to increase the force that drives the sliding block during operation, resulting in a laborious operation.

[0011] Therefore, the existing buckle positioning device of the electronic card (solid state hard disk) has the above-mentioned shortcomings in practical application and needs further improvement. Utility Model Content

[0013] Another object of the utility model is to provide a fastening device for an electronic card, wherein the two end portions of the guide portion corresponding to the direction of the active path are respectively provided with an inclined surface facing the direction of the locking position and an arc surface facing the direction of the release position; the inclined surface acts on the stop portion (or the side of the stop portion) to enable the guide portion to gradually push against the elastic arm to produce elastic bending deformation, so that the guide portion moves from the release position to the locking position through the stop portion, and the arc surface can guide the guide portion to move from the locking position to the release position through the stop portion when the elastic arm is bent and deformed by external force, so that the guide portion can smoothly pass through the stop portion to improve the overall control action quality.

[0046] Please refer to Figures 1 to 3 As shown, the structure of the utility model includes: a base 1 and a movable card member 2. The base 1 can be fixed on a motherboard 30 by bonding, welding or assembling with other components, and is located beside the location where the electronic card 3 (which can be a solid state drive) is set.

[0047] A accommodating space 13 is recessed on the top surface of the base body 1, and two corresponding pivotally connected portions 11 (which may be shaft holes) are provided on the inner wall surface of the accommodating space 13, and an opening groove 111 is provided on the inner wall surface of the accommodating space 13, and the opening groove 111 extends from the pivotally connected portion 11 toward the opening of the accommodating space 13; an arc-shaped extending limiting guide groove 12 is provided on the side of the pivotally connected portion 11, and a stopping portion 14 is provided on one end (side) of the limiting guide groove 12 close to the top of the base body 1.

[0048] The movable clamping member 2 is provided with a pivoting portion 23 (which may be a convex shaft) in the middle portion. The pivoting portion 23 can extend into the opening slot 111 and be coupled to the pivotally coupled portion 11 , so that the movable clamping member 2 can be pivotally coupled to the base 1 .

[0049] The movable clamping member 2 has a clamping end 21 and an operating end 22 at both ends. A recess 24 is formed on the end surface of the operating end 22, so that elastic arms 221 extending in parallel are formed on both sides of the recess 24. A guide portion 222 (which can be a bump) is convexly provided on one side of each elastic arm 221 away from the recess 24. The movable path of each guide portion 222 can correspond to the limiting guide groove 12, and the limiting guide groove 12 can be used to form a sliding guide for the guide portion 222.

[0050] In the above structure, the guide portion 222 is stopped by the stop portion 14 and can be restricted to a locking position (locked state) and a release position (free state) respectively; and the two ends of the guide portion 222 corresponding to the direction of the active path are respectively provided with a locking end 2231 and a release end 2241, and an inclined surface 223 can be provided on the locking end 2231 as needed, and an arc surface 224 can be provided on the release end 2241 as needed.

[0051] In a feasible embodiment, a positioning notch 310 is provided at the edge of a locking end 31 of the electronic card 3, and the locking end 21 of the movable locking member 2 extends toward the electronic card 3, a positioning protrusion 211 corresponding to the positioning notch 310 is provided on the end surface of the locking end 21, and a pressing portion 212 protruding toward the electronic card 3 is provided above the positioning protrusion 211; and the torque of the operating end 22 of the movable locking member 2 acting on the pivotal portion 23 is greater than the torque of the locking end 21 acting on the pivotal portion 23, so that the movable locking member 2 can maintain the release position with the locking end 21 tilted upward in a natural state without force (such as Figure 2 as shown).

[0052] In actual application, if the electronic card 3 is to be assembled, the electrical connection end 32 of the electronic card 3 with the pins can be plugged into a terminal seat 40. At this time, the card end 31 of the electronic card 3 with the positioning notch 310 remains elastically upturned, and the movable card member 2 is in the release position (such as Figure 3 Then, the user can directly press down the electronic card 3, so that the card end 31 gradually contacts and presses the positioning protrusion 211 to slide downward, and the movable card member 2 pivots around the pivoting portion 23, and at the same time, the operating end 22 (guide portion 222) of the movable card member 2 moves along the limiting guide groove 12 toward the stop portion 14 (as shown in FIG. Figure 4 as shown).

[0053] During the above-mentioned displacement activity, when the guide portion 222 of the movable clamping member 2 contacts the stop portion 14 (or the inner side wall of the seat body 1) with the clamping end 2231, the inclined surface 223 can be used to guide the elastic arm 221 to gradually bend and deform toward the recess 24, so that the guide portion 222 can gradually pass through the stop portion 14; when the electronic card 3 continues to press the movable clamping member 2 downward until the positioning protrusion 211 is embedded in the positioning notch 310, and the pressing portion 212 is stopped at the recess 24. The upper portion of the end edge of the positioning notch 310 can keep the electronic card 3 in a firmly positioned (locked) state, and the positioning protrusion 211 is embedded in the positioning notch 310, which can provide a lateral stabilization effect on the electronic card 3, thereby preventing the electrical connection of the electrical connection end 32 from being misaligned due to unexpected lateral deviation; at this time, the guide portion 222 is displaced from the release position to the locking position through the stop portion 14, and the guide portion 222 is blocked by the stop portion 14 and cannot easily return to the release position (such as Figure 5 As shown), to maintain the card positioning state of the electronic card 3.

[0054] If the assembled electronic card 3 is to be disassembled, an external force can be applied to the elastic arm 221 of the movable card member 2 to cause the elastic arm 221 to be elastically bent and deformed toward the concave portion 24 (such as Figure 6 As shown in the figure, the electrical connection end 32 of the electronic card 3 is acted upon by the terminal seat 40 so that the card end 31 has the elasticity to bend upward, and the movable card member 2 maintains the tendency of the card end 21 to bend upward in the natural state, and the guiding and sliding effect of the arc surface 224 of the release end 2241 can make the guide portion 222 pass through the stopper 14 smoothly, so that the operating end 22 returns from the card position to the release position; at this time, the positioning protrusion 211 and the pressing portion 212 move out of the position of the positioning notch 310 of the electronic card 3, and the elasticity of the electrical connection end 32 of the electronic card 3 is applied by the terminal seat 40, so that the card end 31 with the positioning notch 310 can bend upward to a position that is easy to disassemble (as shown in the figure). Figure 7 shown).

[0055] It should be noted that the seat body 1 is provided with only a single stopper 14 and a limiting guide groove 12 ; and correspondingly, the movable clamping member 2 is provided with only a single elastic arm 221 and a guiding portion 222 , and in actual application, the same operation can achieve the same effect.

[0056] The above structure of the utility model has the following characteristics:

[0057] 1. Compared with the traditional structure, the utility model does not need to set an elastic member (spring) between the seat body 1 and the movable clamping member 2, which helps to reduce the overall parts cost and assembly difficulty.

[0058] 2. The movable latching member 2 of the utility model utilizes its own gravity moment distribution design, so that the movable latching member 2 can be maintained in a released position with the latching end 21 tilted upward in a natural state without being subjected to force; therefore, its structural design does not require a structure for tilting the latching end 21 upward, which can effectively simplify the overall structure.

[0059] 3. When disassembling the electronic card 3, the utility model only needs to directly push the elastic arm 221 to bend it by hand, and then the subsequent disassembly action can be performed. No tools are required during the operation, which is convenient to use.

[0060] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
