Description

Interface card positioning quick release device

The present invention provides a positioning quick release device for an interface card, and in particular, a reference positioning member and a deflection positioning member of the positioning quick release device can be placed in two lock slots of the interface card and locked. During the process of rotating the lock for positioning, the reference positioning member is kept aligned with one lock slot without deviation. Before assembly, the top side of the deflection positioning member forms a slight misalignment with the other lock slot, but a lateral stress is generated when the top side guiding inclined surface of the deflection positioning member contacts the bottom side of the lock slot, so that the deflection positioning member generates a lateral deflection. The tilting angle is set and the elastic part is compressed so that it can be smoothly inserted into the lock slot. After the positioning and docking end of the interface card is pressed down to the locking position, the deflecting positioning part is returned to the vertical position by the restoring force of the elastic part and the interface card is pushed horizontally for a distance. The relative inner side or outer side of the reference positioning part and the deflecting positioning part are supported on the two lock slots to form a locking position, so that the interface card assembly does not require hand tools and has the purpose of simple operation and stable positioning.

According to the current computer technology, which is growing at a rapid pace, the development trend of computers is mainly towards powerful computing functions, fast speed and small size, which has led to a decrease in the number of communication ports and recording media devices (such as disk drives, hard disks, optical disk drives, burners, etc.) of computer-related peripherals. The fixing or disassembly method between the computer housing and the recording media devices contained inside must be simpler and should not occupy too much space, in order to effectively respond to the trend of computers becoming smaller and smaller.

As mentioned above, a general server chassis, storage cabinet or electronic cabinet has a large number of media storage devices (such as hard disk drives (HDD) or solid state drives (SSD), etc.), and when each media storage device is replaced or maintained, the replacement speed between the outer casing and the media storage device contained therein must be simpler and faster, and the manufacturing cost of the assembly structure and components must be reduced. It is also necessary to take into account the cost and demand of a large number of media storage devices. When the storage cabinet or the telecommunication cabinet is used for a long time, the stability of the entire system and the convenience of maintenance and replacement must be considered to reduce downtime and manpower losses when maintenance personnel are performing maintenance. Most of the media storage devices currently used are fixed in the storage cabinet or the telecommunication cabinet. The screw locking method is to use screws, and it takes a long time to screw the screws in and out of the fixing screw holes, which greatly increases the downtime for maintenance. If the rack of the server chassis is very thin and the height between the frames is not high, and the inside of the chassis is full of interfering objects such as interface cards, hard drives and power cables, it is very inconvenient to insert the screwdriver to lock it, and it may even cause the screws to break. When the screw is locked, it may fall off and be lost. If the screw is not the right size and is locked with force, it is easy to make the fixing screw hole on the media storage device slip, which is not conducive to assembly or disassembly. In addition, some media storage devices are fixed by snapping with springs, but when the rack or server chassis is hit or vibrated during transportation, it is very easy to fall off, fall off and cause damage. Based on the various shortcomings of the above-mentioned computer components during maintenance, how to design a structure that is stable in positioning and easy to disassemble has become a goal that people in this industry are eager to work hard for.

Therefore, in view of the above problems and deficiencies, the inventor collected relevant information and, after multiple evaluations and considerations, designed the invention of this kind of interface card positioning quick-release device.

The main purpose of the present invention is to provide a positioning quick-release device for an interface card, comprising: a base, which comprises a docking portion and a first accommodating cavity and a second accommodating cavity are respectively recessed inwardly on the side of the docking portion, the docking portion is provided with a fixing groove for a bottom positioning plate of a reference positioning member to be fixed on the top side of the first accommodating cavity, and the docking portion is provided with a movable groove for a deflection positioning member to pass through on the top side of the second accommodating cavity and an axis groove for the bottom positioning axis of the deflection positioning member to pass through and position on the bottom side of the second accommodating cavity, and an elastic member is provided between the deflection positioning member and the inner wall surface of the second accommodating cavity to form a contact and abutment with the two. By means of the above-mentioned structure, the reference positioning member and the deflection positioning member of the positioning quick release device can be placed and locked in the two lock slots of the interface card. During the process of rotating the lock buckle for positioning, the reference positioning member remains aligned with one lock slot without deviation. Before assembly, the top side of the deflection positioning member forms a slight misalignment with the other lock slot. However, when the top side guide inclined surface of the deflection positioning member contacts the bottom side of the lock slot, a lateral stress is generated, so that the deflection positioning member generates a lateral deflection tilt angle and elasticity. The component is compressed and can be smoothly inserted into the lock slot. After the positioning and docking end of the interface card is pressed down to the locking position, the deflection positioning component is returned to the vertical position by the restoring force of the elastic component and the interface card is moved horizontally for a distance. The relative inner side or outer side of the reference positioning component and the deflection positioning component are supported on the two lock slots to form a locking position, so that the interface card assembly does not require hand tools and has the purpose of simple operation and stable positioning.

The secondary purpose of the present invention is that the reference positioning member has a guide head on its top side, and the guide head extends downward to have a retracted positioning ring groove, and the positioning ring groove further extends downward to have the positioning plate.

Another purpose of the present invention is that the deflection positioning member has an operating part on its top side and the operating part extends downward with a retracted positioning ring rod, the positioning ring rod further extends downward with a retracted neck for a gasket to be clamped, the neck further extends downward with an expanded limiting ring rod, and the limiting ring rod extends downward with a limiting block that abuts against the top side of the shaft groove, and the limiting block extends downward with the positioning shaft.

Another purpose of the present invention is that the base extends upwardly with a convex step away from the docking portion, and the two side walls of the convex step are provided with an elliptical shaft hole for positioning the shafts of the two ends of a limit elastic body, and two vertical plates with approximately the same spacing and parallel to each other are provided between the two side walls, and the two vertical plates are each provided with a positioning groove in the docking direction, and the limit elastic body is bent from the two shafts toward the center direction through multiple bends to form an operating section, and the operating section further includes a buckle point that is rotated and laterally buckled into the positioning groove, and the two operating sections are further bent toward the center direction through multiple bends to form a supporting section that contacts the upper surface of the preset interface card.

It can be clearly seen from the figure that the positioning quick release device of the interface card of the present invention mainly includes: a base 1, a reference positioning member 2, a deflection positioning member 3, a gasket 4 and an elastic member 5. Its main components and features are described in detail as follows:

The base 1 includes a docking portion 11 and a first accommodating cavity 111 and a second accommodating cavity 112 are respectively recessed inwardly on the side of the docking portion 11. The docking portion 11 is provided with a fixing groove 1111 for a base positioning member 2 bottom side positioning plate 21 to be clamped at the top side of the first accommodating cavity 111, and the docking portion 11 is provided with a movable groove 1121 for a deflection positioning member 3 to pass through at the top side of the second accommodating cavity 112, and an axis groove 1122 for the bottom side positioning axis 31 of the deflection positioning member 3 to pass through and position at the bottom side of the second accommodating cavity 112.

The reference positioning member 2 has a guide head 22 on its top side, and the guide head 22 has a retracted positioning ring groove 23 extending downward, and the positioning ring groove 23 further extends downward to form the positioning plate 21.

The deflection positioning member 3 has an operating portion 32 on its top side, and the operating portion 32 extends downward to have an inwardly retracted positioning ring rod 33, and the positioning ring rod 33 further extends downward to have an inwardly retracted neck portion 34 for clamping a gasket 4, and the neck portion 34 further extends downward to have an outwardly extended limiting ring rod 35, and the limiting ring rod 35 extends downward to have a limiting block 36 that abuts against the top side of the shaft groove 1122, and the limiting block 36 extends downward to have the positioning shaft 31, and an elastic member 5 is further provided between the limiting ring rod 35 and the inner wall surface of the second accommodating cavity 112 to form a contact and abutment with the two.

The above-mentioned docking portion 11 is provided with an assembly channel 1112 corresponding to the bottom side of the first accommodating cavity 111 for the reference positioning member 2 to penetrate from bottom to top, and the positioning plate 21 of the reference positioning member 2 is assembled in the fixing groove 1111 by a stamping and riveting process.

The assembly channel 1112 and the fixing groove 1111 of the docking part 11 for installing the reference positioning member 2 are both circular, and the diameter of the assembly channel 1112 is larger than that of the fixing groove 1111; the movable groove 1121 of the docking part 11 for the deflection positioning member 3 to be installed and deflected in the horizontal direction is elliptical, and the shaft groove 1122 for the positioning shaft 31 to be installed and positioned is circular, and the diameter of the movable groove 1121 is larger than that of the shaft groove 1122.

Please refer to Figures 13 and 14, which are three-dimensional external views of the positioning quick-release device of the present invention using the auxiliary positioning structure and the interface card for docking and assembly, and three-dimensional exploded views of the positioning quick-release device and the auxiliary positioning structure, wherein the base 1 has a convex step 12 extending upward away from the docking portion 11, and the two side walls of the convex step 12 are provided with an elliptical shaft hole 121 for positioning the shaft 131 at the two ends of a limiting elastic body 13, and two vertical plates 122 with approximately the same spacing and parallel to each other are provided between the two side walls, and the two vertical plates 122 are each provided with a positioning groove 12 21 in the docking direction, and the The limiting elastic body 13 is bent multiple times from the two axis portions 131 toward the center direction to form an operating section 132, and the operating section 132 further includes a buckle point 1321 that is rotated and laterally buckled into the positioning groove 1221, and the two operating sections 132 are further bent multiple times toward the center direction to form a supporting section 133 that contacts the upper surface of the preset interface card 7. Through the above-mentioned structure, after the reference positioning member 2 and the offset positioning member 3 of the base 1 are inserted into the two locking grooves 711 of the interface card and the buckle is completed, the auxiliary positioning structure disclosed in Figures 13 and 14 can make the buckle structure between the positioning quick release device and the interface card 7 more stable. The default interface card 7 refers to a solid state hard disk (SSD) of E1.S specification. The default interface card 7 is provided with two locking grooves 711 at the positioning docking end 71 for the reference positioning member 2 and the offset positioning member 3 to penetrate and lock, and the two locking grooves 711 are grooves that are wide at the top and narrow at the bottom.

The length of the above-mentioned reference positioning member 2 is smaller than that of the deflection positioning member 3; and the top of the guide head 22 of the reference positioning member 2 and the operating portion 32 of the deflection positioning member 3 both have a downwardly inclined guide surface.

The gasket 4 is a C-shaped gasket with a plurality of abutting portions 41 protruding from the inside; and the elastic member (5, 6) is a V-shaped metal spring (as shown in Figure 3) or a torsion spring (as shown in Figure 10).

When assembling the positioning quick-release device of the present invention, firstly, the guide head 22 of the reference positioning member 2 is inserted into the assembly channel 1112 of the base 1 from bottom to top, and the positioning plate 21 of the reference positioning member 2 is assembled in the fixed groove 1111 by a stamping and riveting process. Then, the positioning shaft 31 of the deflection positioning member 3 is inserted into the active groove 1121 from top to bottom, and the bottom side positioning shaft 31 is inserted and positioned in the shaft groove 1122. At the same time, the positioning ring rod 33 of the deflection positioning member 3 is located at the active groove 1121. The C-shaped gasket 4 is used to engage with the neck 34 of the deflection positioning member 3 with its opening and then turned so that the opening of the C-shaped gasket 4 faces outward, so that the deflection positioning member 3 will not be separated from the base 1 upward. In addition, the V-shaped elastic member 5 is engaged and positioned between the inner wall surface of the side plate of the second accommodating cavity 112 and the limiting ring rod 35 of the deflection positioning member 3 with the bending part, and the assembly of the positioning quick release device is completed by the above.

Please refer to Figures 1-2, 5-8, which are action diagrams of the positioning quick release device and the interface card of the present invention, wherein the interface card 7 has an exposed electronic substrate on the side away from the positioning quick release device and a plurality of contacts on the electronic substrate (not shown in the figure), and the electronic substrate of the interface card 7 is obliquely inserted into an electrical connector (not shown in the figure) provided on the internal circuit board of the preset electronic device. The interface card 7 uses the electrical connector as a fulcrum to rotate the positioning docking end 71 downward, and the reference positioning member 2 and the offset positioning member 3 located in the base 1 are located at the bottom of the interface card 7 and are respectively aligned with the two lock grooves 711 of the positioning docking end 71. During the process of rotating the lock buckle for positioning, the reference positioning member 2 remains aligned with one lock groove 711 without deviation, but the operating portion 32 on the top side of the offset positioning member 3 is The other locking groove 711 is slightly misaligned, and the top side guide slope of the operating portion 32 of the deflection positioning member 3 contacts the bottom side of the locking groove 711 to generate a lateral stress, so that the deflection positioning member 3 generates a lateral deflection tilt angle away from the center direction and the elastic member 5 is compressed so that it can smoothly penetrate into the locking groove 711. When the positioning docking end 71 of the interface card 7 is pressed down to the positioning ring rod 33, After reaching the locking position, the deflection positioning member 3 is returned to the vertical position by the restoring force of the elastic member 5 and the interface card 7 is moved horizontally toward the center for a certain distance. The positioning ring groove 23 of the reference positioning member 2 and the relative inner sides of the positioning ring rod 33 of the deflection positioning member 3 are supported on the two locking grooves 711 to form a locking position. The positioning quick release device and the interface card 7 are assembled together by the above.

Based on the above, when the positioning quick release device and the interface card 7 are to be unlocked and separated, it is only necessary to apply force to the operating portion 32 of the deflection positioning member 3 to tilt it away from the center, and the interface card 7 is also moved horizontally away from the center for a distance, and then the positioning docking end 71 of the interface card 7 can be rotated and pulled up to make the two locking grooves 711 disengage from the reference positioning member 2 and the deflection positioning member 3 at the same time, and the interface card 7 can be obliquely pulled away from the electrical connector of the preset electronic device, and the purpose of separating the positioning quick release device and the interface card 7 can be completed.

Please refer to Figures 9 to 12, which are respectively a three-dimensional exploded view of another implementation structure of the positioning quick-release device of the present invention and an interface card, a three-dimensional exploded view of another implementation structure of the positioning quick-release device, and the first and second action views of the docking assembly of another implementation structure of the positioning quick-release device and the interface card. Compared with the technical content disclosed in Figures 1 to 8, the only difference is that the elastic member 6 used in this embodiment is a torsion spring to replace the elastic member 5 used in the first embodiment as a V-shaped metal spring, and there is no difference in the remaining components. The only difference in assembling the elastic member 6 formed by the torsion spring inside the positioning quick-release device is that when assembling the deflection positioning member 3, the center coil of the torsion spring needs to be aligned between the movable groove 1121 and the axial groove 1122, and then the deflection positioning member 3 is inserted into the center coil of the torsion spring and positioned at the limiting ring rod 35, and the two ends of the torsion spring are respectively supported on the two side inner wall surfaces of the second accommodating cavity 112, and the rest of the assembly process is no different from the first embodiment. However, since the position of the elastic member 6 formed by the torsion spring against the second accommodating chamber 112 is different from that of the first embodiment, the action flow disclosed in FIGS. 11 and 12 is slightly different from that in FIGS. 5 to 8. The difference is that when the top guide inclined surface of the operating portion 32 of the deflection positioning member 3 contacts the bottom side of the locking groove 711, a lateral deflection tilt angle is generated toward the center direction, and the torsion spring formed The two abutting ends of the elastic member 6 form an extension near the center and a compression near the side plate of the docking portion 11. Therefore, when the deflection positioning member 3 is returned to the vertical position away from the center by the restoring force of the elastic member 6, the relative outer sides of the positioning ring groove 23 of the reference positioning member 2 and the positioning ring rod 33 of the deflection positioning member 3 will be abutted against the two locking grooves 711 to form a locked position. When the positioning quick release device and the interface card 7 are unlocked and separated, it is only necessary to apply force to the operating portion 32 of the deflection positioning member 3 to tilt it toward the center, and the interface card 7 is also pushed horizontally toward the center. The rest of the actions are the same as those of the first embodiment.

The main feature of the present invention is that the reference positioning member 2 and the deflection positioning member 3 of the positioning quick release device can be placed and locked in the two lock slots 711 of the interface card 7. During the process of rotating the lock to position, the reference positioning member 2 remains aligned with one lock slot 711 without deviation. Before assembly, the top side of the deflection positioning member 3 forms a slight misalignment with the other lock slot 711. However, when the top side guide inclined surface of the deflection positioning member 3 contacts the bottom side of the lock slot 711, a lateral stress is generated, so that the deflection positioning member 3 generates a lateral deflection tilt angle and bounces. The elastic member (5 or 6) is compressed and can be smoothly inserted into the lock groove 711. After the positioning and docking end 71 of the interface card 7 is pressed down to the locking position, the deflection positioning member 3 is returned to the vertical position by the restoring force of the elastic member (5 or 6) and the interface card is moved horizontally for a distance. The relative inner side or the relative outer side of the reference positioning member 2 and the deflection positioning member 3 are supported on the two lock grooves 711 to form a locking position, so that the interface card 7 can be assembled without the need for hand tools and has the purpose of simple operation and stable positioning. This invention has excellent practicality in the production of positioning quick-release devices for E1.S specification solid state hard drives (SSDs), so a patent application is filed to seek patent protection.

The above is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Therefore, all simple modifications and equivalent structural changes made by using the contents of the present invention's specification and drawings should be included in the patent scope of the present invention and should be stated.

In summary, the positioning quick release device of the interface card of this invention can truly achieve its effect and purpose when used. Therefore, this invention is truly an invention with excellent practicality. In order to meet the application requirements of invention patents, an application is filed in accordance with the law. I hope that the review committee will approve this case as soon as possible to protect the inventor's hard work. If the review committee of the Jun Bureau has any doubts, please feel free to write to instruct. The inventor will do his best to cooperate and feel very grateful.
