Description

Technical Field

[0001] This invention relates to the field of computers, and more particularly to a fixture and server for M.2 boards of different lengths. Background Technology

[0002] Modern M.2 and other small SSD cards come in various lengths. To support these different lengths, the motherboard needs perforations. These perforations serve two main purposes: first, they are round holes to allow for the soldering of SMT-type studs. After the M.2 card is assembled, it is secured to the studs with screws. Second, tool-free plastic clips are used to secure the M.2 card within the perforations, preventing it from popping out. The numerous perforations on the board also restrict wiring, making it difficult to implement and necessitating the addition of more layers, thus increasing product costs. Summary of the Invention

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0037] Based on the above objectives, a first aspect of the embodiments of the present invention provides an embodiment of a retainer for M.2 boards of different lengths. Figure 1-6 The diagram shown is a schematic of the fastener.

[0038] like Figure 1-6 As shown, the fastener may include:

[0039] M.2 board connector 1 is fixedly mounted on the base plate for connecting M.2 boards. In some embodiments, M.2 board connector 1 has a single-layer structure. In some embodiments, M.2 board connector 1 has a double-layer structure, that is, it can connect two M.2 boards simultaneously.

[0040] It also includes an adsorption part 2, which is disposed at a preset position on the base plate. The adsorption part 2 can be configured as an upward protrusion on the base plate, the top surface of which is made of magnetic material, or the protrusion itself is made of magnetic material, or a magnet 4 is disposed on the protrusion. In some embodiments, five protrusions can be disposed on the base plate. The distance between the first protrusion and the M.2 board connector 1 is approximately 30 mm, the distance between the second protrusion and the M.2 board connector 1 is approximately 42 mm, the distance between the third protrusion and the M.2 board connector 1 is approximately 60 mm, the distance between the fourth protrusion and the M.2 board connector 1 is approximately 80 mm, and the distance between the fifth protrusion and the M.2 board connector 1 is approximately 110 mm. The distances of these five protrusions to the M.2 board connector 1 are approximately the same as the lengths of the five different lengths of M.2 connectors. The specific distances can be adjusted appropriately. When M.2 boards of different lengths are connected to the M.2 board connector 1, the protrusions disposed at the corresponding positions cooperate with the adjusting fasteners 3 to fix the M.2 boards. In some embodiments, the adsorption part 2 can be configured as a long strip magnet, which is disposed on the base plate and has a length greater than 110 mm. In some embodiments, a protrusion can be configured, with the starting end of the protrusion being less than 30 mm from the M.2 board connector 1 and the ending end being greater than 110 mm from the M.2 board connector 1. When M.2 boards of different lengths are connected to the M.2 board connector 1, the magnet 4 on the adjusting fastener 3 can be adsorbed onto the protrusion to fix the M.2 board.

[0041] The device also includes an adjusting fastener 3, which is equipped with a magnet 4 and a protrusion 5 that matches the recessed portion at the tail end of the M.2 board. When the M.2 board is connected to the M.2 board connector 1, the adjusting fastener 3 is configured to insert the protrusion 5 into the recess and fix the adjusting fastener 3 with the magnet 4 to secure the M.2 board. In some embodiments, a magnet 4 is provided on the bottom surface of the adjusting fastener 3, and a protrusion 5 is provided on one side of the adjusting fastener 3. When the protrusion 5 of the adjusting fastener 3 is inserted into the recessed portion at the tail end of the M.2 board, the magnet 4 is attracted to one of the five protrusions to secure the M.2 board. In this embodiment, the magnet 4 on the adjusting fastener 3 can be directly attracted to the adsorption part 2 to fix the adjusting fastener 3 in the corresponding position, thereby securing the M.2 board. This embodiment is more suitable for single-layer structure M.2 board connector 1. In some embodiments, the connector further includes an adjusting fastener bracket 6. The first end of the adjusting fastener bracket 6 is fixed to the side of the M.2 board connector 1, and the second end is fixed to the base plate. The adjusting fastener bracket 6 is provided with a magnetic attraction part 7, and the magnet 4 of the adjusting fastener 3 is attracted to the magnetic attraction part 7 to fix the adjusting fastener 3. In some embodiments, the adjusting fastener bracket 6 is provided with five magnetic attraction parts 7. The distance between the first magnetic attraction part and the M.2 board connector 1 is 30mm, the second magnetic attraction part is 42mm, the third magnetic attraction part is 60mm, the fourth magnetic attraction part is 80mm, and the fifth magnetic attraction part is 110mm. The distance from the five magnetic attachments to the M.2 connector 1 is approximately the same as the length of the five different M.2 connectors. The specific distance can be adjusted appropriately. When M.2 boards of different lengths are connected to the M.2 connector 1, the magnetic attachments 7 at the corresponding positions cooperate with the magnets 4 of the adjusting fastener 3 to fix the M.2 boards. In some embodiments, the adjusting fastener bracket 6 is provided with an upper row of magnetic attachments and a lower row of magnetic attachments. The upper and lower rows of magnetic attachments are provided in the same position and number. The adjusting fastener 3 includes a first adjusting fastener and a second adjusting fastener. The magnet 4 of the first adjusting fastener is attracted to the upper row of magnetic attachments to fix the first adjusting fastener 3, and the magnet 4 of the second adjusting fastener is attracted to the lower row of magnetic attachments to fix the second adjusting fastener 3. In this embodiment, two M.2 boards can be installed at the same time. By adjusting the positions of the first adjusting fastener and the second adjusting fastener, the two M.2 boards can be fixed respectively.

[0042] The technical solution of this invention enables the fixing of M.2 boards without drilling holes on the PCB board, thereby increasing the space for wiring. It also allows for tool-free adjustment of the position of the fixing device to support M.2 boards of different lengths and positions, and has the advantages of simple structure and low cost.

[0043] In a preferred embodiment of the invention, the adsorption part 2 is configured as a protrusion on the base plate, the top surface of which is made of magnetic material. The protrusion is a portion that bulges upwards from the base plate and can be designed as a solid protrusion. A solid protrusion can be any shape with a flat top surface, and its body can be designed as a magnet, or at least its top surface can be made of magnetic material. The protrusion can also be designed as a hollow protrusion, generally trapezoidal, with its top surface also made of magnetic material. In this embodiment, the protrusion is designed to cooperate with the magnet 4 on the adjusting fastener 3; that is, the two need to be adsorbed together to fix the adjusting fastener 3.

[0044] In a preferred embodiment of the present invention, five protrusions are provided on the base plate. The distance between the first protrusion and the M.2 board connector 1 is 30mm, the distance between the second protrusion and the M.2 board connector 1 is 42mm, the distance between the third protrusion and the M.2 board connector 1 is 60mm, the distance between the fourth protrusion and the M.2 board connector 1 is 80mm, and the distance between the fifth protrusion and the M.2 board connector 1 is 110mm. M.2 and other small SSD cards come in various lengths, including 30mm, 42mm, 60mm, 80mm, and 110mm. The distance from the protrusion to the M.2 card connector 1 is roughly the same as the length of the five card types. However, this distance can be fine-tuned depending on the specific situation. For example, when the M.2 card connector 1 is connected to a 30mm long M.2 card, the first protrusion is roughly located at the tail end of the card. When the protrusion 5 of the adjusting clip 3 is inserted into the tail end of the M.2 card, the magnet 4 on the adjusting clip 3 will attract the first protrusion, thus fixing the adjusting clip 3 and securing the 30mm long M.2 card. When M.2 cards of other lengths are connected to the M.2 card connector 1, the protrusion at the corresponding position can attract the magnet 4 of the adjusting clip 3, using the same principle.

[0045] In a preferred embodiment of the present invention, a magnet 4 is provided on the bottom surface of the adjusting buckle 3, and a protrusion 5 is provided on one side of the adjusting buckle 3. When the protrusion 5 of the adjusting buckle 3 is inserted into the recess at the tail end of the M.2 board, the magnet is attracted to one of the five protrusions to fix the M.2 board.

[0046] In a preferred embodiment of the present invention, it further includes:

[0047] An adjustment fastener bracket 6 is provided, with its first end fixed to the side of the M.2 board connector 1 and its second end fixed to the base plate. A magnetic suction part 7 is provided on the adjustment fastener bracket 6, and the magnet 4 of the adjustment fastener 3 is attracted to the magnetic suction part 7 to fix the adjustment fastener 3. In a preferred embodiment of the present invention, the first end of the adjustment fastener bracket 6 is fixedly connected to the side of the M.2 board connector 1 by a screw 8, which better secures the adjustment fastener bracket 6 in the corresponding position. In another preferred embodiment of the present invention, the first end of the adjustment fastener bracket 6 is fixedly connected to the side of the M.2 board connector 1 by a snap-fit ​​structure, which facilitates the installation and removal of the adjustment fastener bracket 6. In a preferred embodiment of the present invention, a fixing part 9 is provided at the bottom of the second end of the adjustment fastener bracket 6. The fixing part 9 is made of magnetic material, and the fixing part 9 is attracted to the suction part 2 to fix the adjustment fastener bracket 6. The fixing part 9 is located at the end of the adjusting fastener bracket 6 furthest from the M.2 board connector 1. It can be a magnet, which can be attracted to the adsorption part 2 on the base plate for fixation. The adsorption part 2 is configured as a protrusion on the base plate, the top surface of which is made of magnetic material. The protrusion is the portion that bulges upward from the base plate. It can be designed as a solid protrusion, which can be any shape with a flat top surface. The body of the solid protrusion can be designed as a magnet, or at least the top surface can be made of magnetic material. Alternatively, the protrusion can be designed as a hollow protrusion, generally trapezoidal, with the top surface also made of magnetic material. In this embodiment, the adsorption part 2 serves to attract the fixing part 9 on the adjusting fastener bracket 6, thereby fixing the adjusting fastener bracket 6.

[0048] In a preferred embodiment of the present invention, the adjusting fastener bracket 6 is provided with five magnetic suction parts 7. The distance between the first magnetic suction part and the M.2 board connector 1 is 30mm, the distance between the second magnetic suction part and the M.2 board connector 1 is 42mm, the distance between the third magnetic suction part and the M.2 board connector 1 is 60mm, the distance between the fourth magnetic suction part and the M.2 board connector 1 is 80mm, and the distance between the fifth magnetic suction part and the M.2 board connector 1 is 110mm. M.2 and other small SSD cards come in various lengths, including 30mm, 42mm, 60mm, 80mm, and 110mm. The distance from the magnetic attachment 7 to the M.2 card connector 1 is roughly the same as the length of the five card types. However, this distance can be fine-tuned depending on the specific situation. For example, when the M.2 card connector 1 is connected to a 60mm long M.2 card, the third magnetic attachment is roughly located at the tail end of the card. When the protrusion 5 of the adjusting clip 3 is inserted into the tail end of the M.2 card, the magnet 4 on the adjusting clip 3 will attract the third magnetic attachment, thus fixing the adjusting clip 3 and securing the 60mm long M.2 card. When M.2 cards of other lengths are connected to the M.2 card connector 1, the magnetic attachment 7 at the corresponding position can attract the magnet 4 of the adjusting clip 3, using the same principle.

[0049] In a preferred embodiment of the present invention, a magnet 4 is provided on the bottom surface of the adjusting buckle 3, and a protrusion 5 is provided on one side of the adjusting buckle 3. When the protrusion 5 of the adjusting buckle 3 is inserted into the recess at the tail end of the M.2 board, the magnet is attracted to one of the five magnetic suction parts 7 to fix the M.2 board.

[0050] In a preferred embodiment of the present invention, the adjusting fastener bracket 6 is provided with an upper row of magnetic suction parts and a lower row of magnetic suction parts, the upper and lower rows of magnetic suction parts being arranged in the same position and number. The adjusting fastener 3 includes a first adjusting fastener and a second adjusting fastener. The magnet of the first adjusting fastener is attracted to the upper row of magnetic suction parts to fix the first adjusting fastener, and the magnet of the second adjusting fastener is attracted to the lower row of magnetic suction parts to fix the second adjusting fastener. In this embodiment, the M.2 board connector 1 has a double-layer structure, that is, it can connect two M.2 boards simultaneously. Since the upper and lower magnetic suction parts are positioned and numbered in the same way, the upper and lower magnetic suction parts at the same position can be called magnetic suction part pairs. That is, there are five magnetic suction part pairs on the adjusting fastener bracket 6. The distance between the first magnetic suction part pair and the M.2 board connector 1 is 30mm, the distance between the second magnetic suction part pair and the M.2 board connector 1 is 42mm, the distance between the third magnetic suction part pair and the M.2 board connector 1 is 60mm, the distance between the fourth magnetic suction part pair and the M.2 board connector 1 is 80mm, and the distance between the fifth magnetic suction part pair and the M.2 board connector 1 is 110mm. M.2 and other small SSD cards come in many different lengths, including 30mm, 42mm, 60mm, 80mm, and 110mm. The distance from the magnetic attachment 7 to the M.2 card connector 1 is roughly the same as the length of the five types of cards. The specific distance can also be fine-tuned according to the actual situation. For example, when a 60mm long M.2 card is connected to the lower layer of the M.2 card connector 1, the position of the third magnetic attachment pair is roughly at the tail of the card. At this time, when the protrusion of the second adjustment clip is inserted into the tail of the M.2 card, the magnet on the second adjustment clip will just attract the lower magnetic attachment of the third magnetic attachment pair to fix the adjustment clip, thereby fixing the 60mm long M.2 card. Simultaneously, when an 80mm long M.2 board is connected to the upper layer of M.2 board connector 1, the fourth magnetic attraction pair is roughly located at the tail end of the board. When the protrusion of the first adjusting fastener is inserted into the tail end of the M.2 board, the magnet on the first adjusting fastener attracts the upper row of magnetic attraction parts of the fourth magnetic attraction pair, thus fixing the adjusting fastener and securing the 80mm long M.2 board. Therefore, in this embodiment, two M.2 boards of different lengths can be connected simultaneously and secured separately. When M.2 boards of other lengths are connected to the upper or lower layer of M.2 board connector 1, the magnetic attraction parts at the corresponding positions can attract the magnets of the adjusting fastener, following the same principle.

[0051] In a preferred embodiment of the present invention, the adjusting fastener bracket is provided with five magnetic suction parts. The distance between the first magnetic suction part and the M.2 board connector is 30mm, the distance between the second magnetic suction part and the M.2 board connector is 42mm, the distance between the third magnetic suction part and the M.2 board connector is 60mm, the distance between the fourth magnetic suction part and the M.2 board connector is 80mm, and the distance between the fifth magnetic suction part and the M.2 board connector is 110mm. The adjusting fastener includes a first adjusting fastener and a second adjusting fastener. A magnet is provided at the bottom of the first adjusting fastener, and the magnet of the first adjusting fastener can be attracted to the upper surface of the magnetic suction part. A magnet is provided at the top of the second adjusting fastener, and the magnet of the second adjusting fastener can be attracted to the lower surface of the magnetic suction part. For example, when a 60mm long M.2 board is connected to the lower layer of the M.2 board connector, the third magnetic attachment is roughly located at the tail of the board. When the protrusion of the second adjusting clip is inserted into the tail of the M.2 board, the magnet on the top of the second adjusting clip attracts the lower surface of the third magnetic attachment, thus fixing the adjusting clip and securing the 60mm long M.2 board. Similarly, when an 80mm long M.2 board is connected to the upper layer of the M.2 board connector, the fourth magnetic attachment is roughly located at the tail of the board. When the protrusion of the first adjusting clip is inserted into the tail of the M.2 board, the magnet on the bottom of the first adjusting clip attracts the upper surface of the fourth magnetic attachment, thus fixing the adjusting clip and securing the 80mm long M.2 board. Therefore, in this embodiment, two M.2 boards of different lengths can be connected simultaneously and secured separately, requiring only one row of magnetic attachments.

[0052] In a preferred embodiment of the present invention, a magnet is provided on the bottom surface of the first adjusting fastener, and a protrusion is provided on one side of the first adjusting fastener. When the protrusion of the first adjusting fastener is inserted into the recess at the tail end of the M.2 board, the magnet of the first adjusting fastener is attracted to one of the upper row of magnetic suction parts to fix the upper M.2 board. A magnet is provided on the bottom surface of the second adjusting fastener, and a protrusion is provided on one side of the second adjusting fastener. When the protrusion of the second adjusting fastener is inserted into the recess at the tail end of the M.2 board, the magnet of the second adjusting fastener is attracted to one of the lower row of magnetic suction parts to fix the lower row of M.2 boards.

[0053] The technical solution of this invention enables the fixing of M.2 boards without drilling holes on the PCB board, thereby increasing the space for wiring. It also allows for tool-free adjustment of the position of the fixing device to accommodate M.2 boards of different lengths and positions, and has the advantages of simple structure and low cost.

[0054] Based on the above objectives, a second aspect of the embodiments of the present invention provides a server, the server including a fixture for M.2 boards of different lengths, the fixture for M.2 boards of different lengths comprising:

[0055] The M.2 board connector is fixedly mounted on the base plate for connecting M.2 boards. In some embodiments, the M.2 board connector has a single-layer structure. In some embodiments, the M.2 board connector has a double-layer structure, meaning it can connect two M.2 boards simultaneously.

[0056] It also includes an adsorption part, which is disposed at a preset position on the base plate. The adsorption part can be configured as an upward protrusion on the base plate, the top surface of the protrusion being made of magnetic material, or the protrusion itself being made of magnetic material, or a magnet being disposed on the protrusion. In some embodiments, five protrusions can be disposed on the base plate. The distance between the first protrusion and the M.2 board connector is approximately 30 mm, the distance between the second protrusion and the M.2 board connector is approximately 42 mm, the distance between the third protrusion and the M.2 board connector is approximately 60 mm, the distance between the fourth protrusion and the M.2 board connector is approximately 80 mm, and the distance between the fifth protrusion and the M.2 board connector is approximately 110 mm. The distances of these five protrusions to the M.2 board connector are approximately the same as the lengths of the five different lengths of M.2 connectors. The specific distances can be adjusted appropriately. When M.2 boards of different lengths are connected to the M.2 board connectors, the protrusions disposed at the corresponding positions cooperate with the adjusting fasteners to fix the M.2 boards. In some embodiments, the adsorption part can be configured as a long strip magnet, which is disposed on the base plate and has a length greater than 110 mm. In some embodiments, a protrusion can be configured, with the starting end of the protrusion being less than 30 mm from the M.2 board connector and the ending end being greater than 110 mm from the M.2 board connector. When M.2 boards of different lengths are connected to the M.2 board connector, the magnet on the adjusting fastener can be adsorbed onto the protrusion to fix the M.2 board.

[0057] The device also includes an adjustment fastener, which has a magnet and a protrusion that matches the recess at the tail end of the M.2 board.
