Description

Electronic card fastening device

This invention relates to a buckling device for an electronic card, and in particular to a buckling structure for an electronic card (such as a solid state drive) that is simple in structure, easy to assemble, and easy to operate.

The traditional solid state drive (SSD) standard is the mSATA standard, but it is limited by the number of flash memories that can be arranged on the printed circuit board (PCB), resulting in a limited overall capacity. Therefore, the newer NGFF (Next Generation Form Factor; also known as M.2) standard for solid state drives was created. Since the M.2 standard can arrange flash memory chips on both sides of the circuit board, it has a smaller size and higher capacity than the traditional mSATA standard, and also has the advantage of helping to reduce costs.

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

In the invention case of the Republic of China Patent Publication No. I568334, an assembly fastener is disclosed, comprising: a bearing portion, a hinge portion, a protruding portion and a pressing portion; the bearing portion has a bearing surface and a back surface opposite to each other. The hinge 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 hinge portion. The pressing portion protrudes from one side of the protruding portion and extends along the radial direction of the hinge 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.

When the above structure is used, the assembly clip can insert the hinge part into the corresponding assembly hole on the computer motherboard according to the specifications of the solid state hard disk, and a tool (such as a flat-blade screwdriver) is inserted into the preset operating groove on the protrusion to rotate the protrusion of the assembly clip so that the locking groove and the release notch located on two opposite sides can face the solid state hard disk respectively, thereby forming different states such as fixed or released; however, when this device is actually used, it must be operated with a specific tool (a flat-blade screwdriver), and the operation method of rotating the protrusion is also more troublesome, and the effect of easy operation cannot be achieved.

In addition, a retaining device assembly is disclosed in the invention case of Chinese patent publication No. CN 109659727A, wherein the retaining device has a main body component arranged on a circuit board, and at least one clamping member is accommodated inside the main body component. A clamping portion is provided in a recessed manner on one side of the clamping member, and a spring sheet or elastic member that can resist the clamping member is further provided inside the main body component, so that the clamping member can maintain a stretchable and skewed elasticity.

In actual application, the edge of the electronic card (solid state hard disk) can be directly pressed down from the top of the card holder, so that the card holder produces elastic movements of compression and deflection, and the engaging portion is clamped around the notch of the edge of the electronic card (solid state hard disk) 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.

In China Patent Bulletin CN Utility Model Case No. 214409847U discloses an M.2 card quick-disassembly buckle, which has a fixed seat and a sliding block. The fixed seat is provided with obliquely extending sliding grooves on both sides. The sliding block is provided with outwardly protruding guide posts on both sides. The guide posts can be extended into the sliding grooves 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 posts slide in the sliding grooves, so that the sliding block can simultaneously generate a backward lateral movement and an upward movement above the fixed seat, thereby providing a space for an M.2 card to be embedded downward. 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.

The above structure still needs to rely on the spring assembly to drive the sliding block to return. The overall components are more and the assembly is complicated, which cannot achieve the actual cost reduction effect. In addition, when in use, the horizontal force that drives the sliding block to move horizontally will derive a vertical component force required for the lifting activity, and cause severe friction between the guide column and the sliding groove. In this way, it is necessary to increase the force to drive the sliding block during operation, resulting in a loss of operating effort.

In view of the above-mentioned shortcomings of the conventional electronic card (solid state hard disk) buckle positioning device in actual application, the creator studied ways to improve these shortcomings and finally produced this creation.

The main purpose of this invention is to provide a kind of electronic card fastening device, including: a base fixed on the motherboard and a movable card member pivotally arranged on the base; a blocking portion is arranged on the base, and a clamping end and an operating end are arranged at both ends of the movable card member, the clamping end is facing an electronic card, and the operating end is provided with at least one elastic arm, and a guide portion is arranged on the elastic arm, and the guide portion can move with the pivoting movement of the movable card member, and cooperate with the elastic deformation of the elastic arm to pass through the blocking portion, so that the guide portion can be stopped by the blocking portion. The electronic card is respectively limited to a locking position and a releasing position; when the electronic card is assembled, the locking end is linked to the assembly position by pressing down the edge of the electronic card, so that the operating end can be lifted up, and the guide part can be moved from the releasing position to the locking position through the stopping part; when the electronic card is disassembled, the elastic arm can be pushed horizontally to make the guide part leave the stopping part, so that the guide part can be moved from the locking position to the releasing position through the stopping part, thereby forming a buckling device with a simple structure, convenient loading and unloading, and can be operated without tools.

Another purpose of the present invention 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 movable 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; by utilizing the inclined surface to act on the stop portion (or the side of the stop portion), the guide portion can gradually push against the elastic arm to produce elastic bending and 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, thereby improving the overall control action quality.

In order to provide a more detailed understanding of the above-mentioned purpose, efficacy and features of this creation, the following illustrations are provided as follows:

Please refer to Figures 1 to 3, it can be seen that the structure of the present invention 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 next to the location where the electronic card 3 (which can be a solid state drive) is set.

The top surface of the base body 1 is concavely provided with a receiving space 13, and the inner wall surface of the receiving space 13 is provided with two corresponding pivoted portions 11 (which may be shaft holes), and the inner wall surface of the receiving space 13 is provided with an opening groove 111, and the opening groove 111 extends from the pivoted portion 11 toward the opening of the receiving space 13; an arc-shaped extending limiting guide groove 12 is provided on the side of the pivoted 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.

The movable clamping member 2 is provided with a pivoting portion 23 (which may be a cam) at the middle portion thereof. The pivoting portion 23 may extend through the opening slot 111 and be coupled to the pivoted portion 11 , so that the movable clamping member 2 may be pivotally coupled to the base 1 .

The movable clamping member 2 is provided with a clamping end 21 and an operating end 22 at both ends; wherein the end surface of the operating end 22 is concavely provided with a recess 24, so that elastic arms 221 extending in parallel are formed on both sides of the recess 24, and each of the elastic arms 221 is convexly provided with a guide portion 222 (which can be a convex block) on one side away from the recess 24, and the movable path of each guide portion 222 can just 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.

In the above structure, the guide portion 222 is stopped by the stopping 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.

In a feasible embodiment, a positioning notch 310 is provided at the edge of a card end 31 of the electronic card 3, and the card end 21 of the movable card 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 card 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 card member 2 acting on the hinge portion 23 is greater than the torque of the card end 21 acting on the hinge portion 23, so that the movable card member 2 can maintain the release position with the card end 21 upward in a natural state without force (as shown in FIG. 2).

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 first plugged into a terminal seat 40. At this time, the locking end 31 of the electronic card 3 with the positioning notch 310 remains in an elastic upward state, and the movable card member 2 is located in the release position (as shown in FIG. 3 ); then, the user can directly press down the electronic card 3, so that the locking end 31 gradually contacts the positioning protrusion 211 and slides downward. At this time, 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 is linked to move along the limiting guide groove 12 toward the blocking portion 14 (as shown in FIG. 4 ).

During the above-mentioned displacement movement, when the guide portion 222 of the movable card member 2 contacts the stop portion 14 (or the inner wall of the base body 1) with the locking 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 card member 2 downward, until the positioning protrusion 211 is embedded in the positioning notch 310, and the pressing portion 212 is stopped at the end edge of the positioning notch 310. The upper portion can keep the electronic card 3 in a stable and fixed position (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, avoiding unexpected lateral deviation from causing an error in the electrical connection of the electrical connection terminal 32; at this time, the guide portion 222 moves from the release position through the stop portion 14 to the locking position, and the guide portion 222 is blocked by the stop portion 14 and cannot easily return to the release position (as shown in FIG. 5), so as to maintain the locking position of the electronic card 3.

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 make the elastic arm 221 bend and deform toward the concave portion 24 (as shown in FIG. 6 ). 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 of bending upward, and the movable card member 2 maintains the upward bending trend of the card end 21 in a natural state, so as to cooperate with the arc of the release end 2241. The sliding action of the surface 224 allows the guide portion 222 to pass through the stop portion 14 smoothly, and the operating end 22 returns from the locked position to the released 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 electronic card 3 applies the elasticity of the electrical connection end 32 through the terminal seat 40, so that the locking end 31 with the positioning notch 310 can be tilted upward to a position that is easy to disassemble (as shown in FIG. 7).

It should be noted that the seat 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. In actual application, the same effect can be achieved through the same operation.

The above structure of this creation has the following characteristics:

1. Compared with the traditional structure, the invention does not need to install elastic parts (springs) between the base 1 and the movable clamping part 2, thus helping to reduce the overall parts cost and assembly difficulty.

2. The movable latching member 2 of the present invention utilizes its own gravity moment distribution design to keep the movable latching member 2 in a natural state without force at a release position with the latching end 21 tilted upward; therefore, the structural design does not need to provide a structure for tilting the latching end 21 upward, which can effectively simplify the overall structure.

3. When disassembling the electronic card 3, the invention only needs to push the elastic arm 221 to bend it, and then the subsequent disassembly operation can be performed. No tools are required during the operation, and the invention is convenient to use.

In summary, the buckle device of the electronic card of this invention can achieve the effects of simplified structure, easy assembly and convenient operation, and is indeed a novel and progressive invention, so a new patent application is filed in accordance with the law; however, the above description is only an illustration of the best embodiment of this invention, and all changes, modifications, alterations or equivalent substitutions extended from the technical means and scope of this invention should also fall within the scope of the patent application of this invention.
