Description

Technical Field

[0001] The invention relates to an installation mechanism, in particular to a network card combining device. Background Art

[0002] In servers, network card configurations that comply with the OCP (Open Compute Project) NIC 3.0 standard are now commonly used. Generally, a connector on a connection frame on the motherboard is used to connect the network card, and the network card is electrically connected to the motherboard via the connector. However, to meet the OCP NIC 3.0 specification design requirements, the height of the connectors on the connection frames provided for motherboards of different thicknesses will vary slightly. Therefore, a connection frame specifically corresponding to the motherboard to be connected is required based on the motherboard thickness. In other words, the connectors on the connection frames of motherboards of different thicknesses cannot support and share each other, resulting in poor overall applicability and inconvenience in the assembly and manufacturing process. Therefore, how to design a frame that can support the connection of multiple motherboards of different thicknesses and electrically connect the motherboard to the network card is worthy of further discussion and improvement by practitioners. Summary of the Invention

[0003] Therefore, the purpose of the present invention is to provide a network card combining device with good applicability.

[0004] Therefore, the network card coupling device of the present invention can support the installation of a network card on multiple different types of motherboards. Each motherboard includes a mounting groove unit that is coupled to the network card coupling device. Each mounting groove unit has a connecting edge and two fixed edges extending from opposite ends of the connecting edge in a direction away from the connecting edge. The network card coupling device is coupled to one of the motherboards and includes a frame unit that is mounted in the mounting groove unit of the motherboard and can be coupled to the network card. The frame unit includes a connection frame module that is coupled to the connecting edge of the mounting groove unit and two slide rail modules that extend from opposite ends of the connection frame module in a direction away from the connection frame module and correspond to the fixed edges of the mounting groove unit. The connection frame module has a connection slot that is electrically connected to the motherboard and can be plugged in and connected to the network card. The opposite ends of the network card can be inserted into the slide rail module and can move relative to the slide rail module toward the connection frame module. The slide rail module and the connection frame module together define an installation space for accommodating the network card.

[0005] In particular, when the thickness of the motherboard to be combined with the network card combining device is a third thickness that is smaller than the second thickness, the fixed edge of the motherboard to be combined is placed on the second step of the slide rail module of the frame unit and fixed on the second step. At this time, the connecting edge of the mounting groove unit of the motherboard is electrically connected to the connecting slot of the frame unit, and the two opposite ends of the network card are inserted into the slide rail module and moved toward the direction of the connecting slot so that the network card is inserted into the connecting slot and electrically connected to the motherboard.

[0006] In particular, each fixed edge of the mounting groove unit of the motherboard of the first thickness has two first fixing parts, and the first fixing part of each fixed edge can be placed on the first step of the corresponding slide rail module and abut against the second step; each fixed edge of the mounting groove unit of the motherboard of the second thickness has two second fixing parts, and the second fixing part of each fixed edge can be placed on the second step of the corresponding slide rail module and abut against the combining step; each fixed edge of the mounting groove unit of the motherboard of the third thickness has two third fixing parts, and the third fixing part of each fixed edge can be placed on the second step of the corresponding slide rail module and abut against the combining step.

[0007] Particularly, the height of the second step of each combining seat of each rail module is equal to half of the difference between the first thickness and the second thickness plus a correction value.

[0008] Specifically, the first thickness is 2.36 mm, the second thickness is 1.93 mm, the third thickness is 1.57 mm, the correction value is 0.3 mm, and the height of the second step of each coupling seat of each slide rail module is (2.36-1.93) mm / 2 plus 0.3 mm, which equals 0.515 mm.

[0009] In particular, it also includes a locking unit for fixing the motherboard to be combined on the frame unit. The locking unit has a plurality of locking pieces, which can be detachably locked into the combining steps of the combining seat of the slide rail module and used to position the motherboard to be combined on the combining seat.

[0010] In particular, it also includes a snap unit, one of the slide rail modules of the frame unit also has a snap groove that penetrates the top surface of the slide rail body, and two snap parts located on two opposite sides of the snap groove and extending upward from the top surface of the slide rail body, the network card has a positioning hole corresponding to the snap groove of the slide rail module, the snap unit has a snap body, a tenon extending from the snap body toward the snap groove of the slide rail module and capable of being snapped into the snap groove and the positioning hole of the network card, and two snap holes that penetrate the snap body and correspond to the snap parts, the snap body of the snap unit is moved toward the snap groove of the corresponding slide rail module and the snap hole is passed through by the snap part, and the tenon is inserted into the snap groove so that the tenon is snapped into the positioning hole of the network card, at this time, the snap part fixes the snap body to the corresponding slide rail module.

[0011] Therefore, another object of the present invention is to provide a motherboard system with good applicability.

[0012] Therefore, the motherboard system of the present invention includes a motherboard, a network card, and a network card coupling device coupled to the motherboard. The motherboard includes a mounting groove unit, the mounting groove unit having a connecting edge, and two fixed edges extending from opposite ends of the connecting edge in a direction away from the connecting edge. The network card coupling device is coupled to the mounting groove unit of the motherboard and includes a frame unit installed in the mounting groove unit of the motherboard and capable of coupling with the network card. The frame unit has a connection frame module coupled to the connecting edge of the mounting groove unit, and two slide rail modules extending from opposite ends of the connection frame module in a direction away from the connection frame module and corresponding to the fixed edges of the mounting groove unit. The connection frame module has a connection slot electrically connected to the motherboard and capable of plugging and connecting the network card. The opposite ends of the network card can be inserted into the slide rail module and can move relative to the slide rail module toward the connection frame module. The slide rail module and the connection frame module together define an installation space for accommodating the network card. Each rail module comprises a rail body connected to the connecting frame module, and two coupling seats spaced apart from the rail body and extending from the rail body away from the installation space for receiving the fixed edges. Each coupling seat of each rail module comprises a first step, a second step disposed on the first step and extending upward from the first step, and a coupling step disposed on the second step and extending upward from the second step. When the thickness of the motherboard combined by the network card combining device is a first thickness, the fixed edge of the motherboard is placed on the first step of the slide rail module of the frame unit and fixed on the first step. At this time, the connecting edge of the mounting groove unit of the motherboard is electrically connected to the connecting slot of the frame unit, and the two opposite ends of the network card are inserted into the slide rail module and moved toward the direction of the connecting slot so that the network card is plugged into and connected to the connecting slot, and the network card is electrically connected to the motherboard; when the thickness of the motherboard combined by the network card combining device is a second thickness smaller than the first thickness, the fixed edge of the motherboard is placed on the second step of the slide rail module of the frame unit and fixed on the second step. At this time, the connecting edge of the mounting groove unit of the motherboard is electrically connected to the connecting slot of the frame unit, and the two opposite ends of the network card are inserted into the slide rail module and moved toward the direction of the connecting slot so that the network card is plugged into and connected to the connecting slot, and the network card is electrically connected to the motherboard.

[0013] In particular, when the thickness of the motherboard to which the network card coupling device is coupled is a third thickness that is smaller than the second thickness, the fixed edge of the motherboard is placed on the second step of the slide rail module of the frame unit and fixed on the second step. At this time, the connection edge of the mounting groove unit of the motherboard is electrically connected to the connection slot of the frame unit, and the two opposite ends of the network card are inserted into the slide rail module and moved toward the connection slot so that the network card is inserted into the connection slot and electrically connected to the motherboard.

DETAILED DESCRIPTION

[0027] Before the present invention is described in detail, it should be noted that similar elements are denoted by the same reference numerals in the following description.

[0028] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 The network card assembly device 1 of the present invention can support the installation of a network card 6 on various types of motherboards 5. Each motherboard 5 includes a mounting groove unit 51 that is coupled to the network card assembly device 1. Each mounting groove unit 51 has a connecting edge 511 and two fixed edges 512 extending from opposite ends of the connecting edge 511 in a direction away from the connecting edge 511. The network card assembly device 1 is coupled to one of the motherboards 5 and includes a frame unit 2 that is mounted in the mounting groove unit 51 of the motherboard 5 and can be coupled to the network card 6.

[0029] The frame unit 2 includes a connection frame module 21 coupled to the connection edge 511 of the mounting recess unit 51, and two rail modules 22 extending from opposite ends of the connection frame module 21 away from the connection frame module 21 and corresponding to the fixed edges 512 of the mounting recess unit 51. The connection frame module 21 has a connection slot 211 electrically connected to the motherboard 5 and adapted for insertion and connection of the network card 6. Opposite ends of the network card 6 can be inserted into the rail modules 22 and moved relative to the rail modules 22 toward the connection frame module 21. The rail modules 22 and the connection frame module 21 together define an installation space 23 for accommodating the network card 6.

[0030] Each rail module 22 includes a rail body 221 connected to the connection frame module 21, and two coupling seats 222 spaced apart from the rail body 221 and extending from the rail body 221 away from the installation space 23 to support the fixed edge 512. Each coupling seat 222 of each rail module 22 includes a first step 223, a second step 224 disposed on the first step 223 and extending upward from the first step 223, and a coupling step 225 disposed on the second step 224 and extending upward from the second step 224.

[0031] When the thickness of the motherboard 5 to be combined with the network card combining device 1 is a first thickness, the fixed edge 512 of the motherboard 5 to be combined is placed on the first step 223 of the combining seat 222 of the slide rail module 22 of the frame unit 2 and fixed on the first step 223. At this time, the connecting edge 511 of the mounting groove unit 51 of the motherboard 5 is electrically connected to the connecting slot 211 of the frame unit 2. The two opposite ends of the network card 6 are inserted into the slide rail module 22 and moved toward the connection slot 211, so that the network card 6 is inserted and connected to the connection slot 211, and the network card 6 is electrically connected to the motherboard 5. When the thickness of the motherboard 5 to be coupled by the network card coupling device 1 is a second thickness that is less than the first thickness, the fixed edge 512 of the motherboard 5 to be coupled is placed on the second step 224 of the slide rail module 22 of the frame unit 2 and fixed on the second step 224. At this time, the connection edge 511 of the mounting groove unit 51 of the motherboard 5 is electrically connected to the connection slot 211 of the frame unit 2. The two opposite ends of the network card 6 are inserted into the slide rail module 22 and moved toward the connection slot 211, so that the network card 6 is inserted and connected to the connection slot 211, and the network card 6 is electrically connected to the motherboard 5.

[0032] When assembling, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 8 If the required bonding thickness is the motherboard 5 of the first thickness, the fixed edge 512 of the motherboard 5 is placed on the first step 223 of the bonding seat 222 of the slide rail module 22 of the frame unit 2 and fixed to the first step 223, so that the connection edge 511 of the mounting groove unit 51 of the motherboard 5 is electrically connected to the connection slot 211 of the frame unit 2 and the center of the connection edge 511 of the motherboard 5 is aligned with the network card 6. Finally, as long as the two opposite ends of the network card 6 are inserted into the slide rail module 22 and moved along the slide rail module 22 toward the connection slot 211 and the network card 6 is plugged into and connected to the connection slot 211, and the network card 6 is electrically connected to the motherboard 5, the assembly action is completed. Relatively speaking, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 6 and Figure 8If the required bonding thickness is the second thickness of the motherboard 5, since the second thickness is smaller than the first thickness, in order to enable the connecting edge 511 of the mounting groove unit 51 of the second thickness motherboard 5 to be electrically connected to the connecting slot 211 of the frame unit 2, the fixed edge 512 of the motherboard 5 is placed on the second step 224 of the coupling seat 222 of the slide rail module 22 of the frame unit 2 and fixed on the second step 224. Since the second step 224 is higher than the first step 223, the connecting edge 511 of the second thickness motherboard 5 is aligned with the connecting slot 211 of the frame unit 2 and the connecting edge 511 of the motherboard 5 can be smoothly electrically connected to the connecting slot 211 of the frame unit 2, and the center of the connecting edge 511 of the motherboard 5 will be lower than the network card 6 by a correction value. Finally, as long as the two opposite ends of the network card 6 are inserted into the slide rail module 22 and moved along the slide rail module 22 toward the connection slot 211, the network card 6 is inserted and connected to the connection slot 211, and the network card 6 is electrically connected to the motherboard 5, the assembly action is completed. It should be further explained that in this embodiment, the height of the second step 224 of each coupling seat 222 of each slide rail module 22 is equal to half of the difference between the first thickness and the second thickness plus a correction value, but is not limited to this. For example, in this embodiment, the first thickness is 2.36mm, the second thickness is 1.93mm, the correction value is 0.3mm, and the height of the second step 224 of each coupling seat 222 of each slide rail module 22 is (2.36-1.93)mm / 2 plus 0.3mm, which is equal to 0.515mm.In other words, due to the design requirements of the OCP NIC 3.0 specification, the motherboard 5 with a thickness of 1.93 mm needs to meet the design requirements that the connecting edge 511 of the mounting groove unit 51 is electrically connected to the connecting slot 211 of the frame unit 2, and the center of the connecting edge 511 of the motherboard 5 needs to be 0.3 mm lower than the network card 6. Therefore, in this embodiment, the second step 224 of the coupling seat 222 of the rail module 22 of the frame unit 2 is designed to accommodate the fixed edge 512 of the motherboard 5 with a thickness of 1.93 mm. When the fixed edge 512 of the motherboard 5 with a thickness of 1.93 mm is placed on the second step 224 of the coupling seat 222 of the rail module 22 of the frame unit 2, the connecting edge 511 of the mounting groove unit 51 of the motherboard 5 with a thickness of 1.93 mm is electrically connected to the connecting slot 211 of the frame unit 2, and the center of the connecting edge 511 of the motherboard 5 is 0.3 mm lower than the network card 6. Relatively speaking, due to the OCP NIC 3.0 standard design requirements, the 2.36mm thick motherboard 5 needs to comply with the design of the connection edge 511 of the mounting groove unit 51 and the electrical connection with the connection slot 211 of the frame unit 2, and the center of the connection edge 511 of the motherboard 5 needs to be aligned with the network card 6. However, if the 2.36mm thick motherboard 5 is directly placed on the second step 224 of the coupling seat 222 of the slide rail module 22 of the frame unit 2, the center of the connection edge 511 of the 2.36mm thick motherboard 5 cannot be aligned with the network card 6 due to the thickness difference. Therefore, in this embodiment, the connection of the slide rail module 22 of the frame unit 2 is designed to be aligned with the network card 6. The first step 223 of the coupling seat 222 is lower than the second step 224 by a height difference of 0.515 mm, so that the first step 223 of the coupling seat 222 can accommodate the fixed edge 512 of the 2.36 mm thick motherboard 5. When the fixed edge 512 of the 2.36 mm thick motherboard 5 is placed on the first step 223 of the slide rail module 22 of the frame unit 2, the connecting edge 511 of the mounting recess unit 51 of the 2.36 mm thick motherboard 5 is electrically connected to the connecting slot 211 of the frame unit 2, and the center of the connecting edge 511 of the motherboard 5 is aligned with the network card 6, but the present invention is not limited to this. In short, the second step 224 of each coupling seat 222 and the corresponding first step 223 form a stepped shape with a height difference of 0.515 mm, which can meet the installation requirements of supporting the required motherboard 5 with a thickness of 1.93 mm or 2.36 mm, but the present invention is not limited to this.

[0033] By means of the design that the coupling seat 222 of the slide rail module 22 of the frame unit 2 can accommodate the fixing edge 512 of the mounting groove unit 51 of the motherboard 5 to be coupled, and the first step 223 of each coupling seat 222 and the corresponding second step 224 are in a stepped shape, the thickness requirement of the motherboard 5 to be coupled can be met. The fixing edge 512 of the motherboard 5 of the first thickness is placed and fixed on the first step 223, so that the connecting edge 511 of the mounting groove unit 51 of the motherboard 5 can be aligned with the first step 223. The connection slot 211 of the frame unit 2 is electrically connected to ensure that the network card 6 is plugged into and connected to the connection slot 211 and that the network card 6 is electrically connected to the motherboard 5, or the fixed edge 512 of the motherboard 5 of the second thickness is placed and fixed on the second step 224 so that the connection edge 511 of the mounting groove unit 51 of the motherboard 5 can be electrically connected to the connection slot 211 of the frame unit 2, to ensure that the network card 6 is plugged into and connected to the connection slot 211 and that the network card 6 is electrically connected to the motherboard 5, thereby achieving high versatility and good applicability.

[0034] Here, we need to further explain that, see Figure 1 、 Figure 3 、 Figure 7 and Figure 10In this embodiment, when the thickness of the motherboard 5 to be coupled to the network card coupling device 1 is a third thickness that is less than the second thickness, the fixed edge 512 of the motherboard 5 to be coupled is placed on the second step 224 of the slide rail module 22 of the frame unit 2 and fixed thereto. At this point, the connecting edge 511 of the mounting groove unit 51 of the motherboard 5 is electrically connected to the connecting slot 211 of the frame unit 2. The opposite ends of the network card 6 are inserted into the slide rail module 22 and moved toward the connecting slot 211, thereby inserting the network card 6 into the connecting slot 211 and establishing an electrical connection between the network card 6 and the motherboard 5. For example, in this embodiment, the third thickness is 1.57 mm, but the present invention is not limited thereto. That is to say, this embodiment can also be applied to the motherboard 5 with a thickness of 1.57 mm. If the required bonding thickness is the motherboard 5 of the third thickness, since the third thickness is also smaller than the first thickness, in order to enable the connecting edge 511 of the mounting groove unit 51 of the motherboard 5 of the third thickness to be electrically connected to the connecting slot 211 of the frame unit 2, the fixed edge 512 of the motherboard 5 is placed on the second step 224 of the coupling seat 222 of the slide rail module 22 of the frame unit 2 and fixed on the second step 224. Since the second step 224 is higher than the first step 223, the connecting edge 511 of the motherboard 5 of the third thickness is aligned with the connecting slot 211 of the frame unit 2 and the connecting edge 511 of the motherboard 5 can be smoothly electrically connected to the connecting slot 211 of the frame unit 2. The center of the connecting edge 511 of the motherboard 5 will be aligned with the network card 6, which meets the standard design requirements of OCP NIC 3.0. Finally, the assembly is complete by inserting the two opposite ends of the network card 6 into the rail module 22 and moving it along the rail module 22 toward the connection slot 211. The network card 6 is then inserted into the connection slot 211 and electrically connected to the motherboard 5. In particular, the motherboard 5, a network card 6, and a network card assembly device 1 coupled to the motherboard 5 can be combined to form a motherboard system. The assembly method is the same as described above and will not be further described here.

[0035] In addition, it should be noted that, in this embodiment, each fixing edge 512 of the mounting groove unit 51 of the mainboard 5 of the first thickness has two first fixing portions 513 (see FIG. Figure 5 、 Figure 8 ), the first fixing portion 513 of each fixing edge 512 can be placed on the first step 223 of the corresponding slide rail module 22 and abut against the second step 224; each fixing edge 512 of the mounting groove unit 51 of the second thickness mainboard 5 has two second fixing portions 514 (see Figure 6 、 Figure 9), the second fixing portion 514 of each fixing edge 512 can be placed on the second step 224 of the corresponding slide rail module 22 and abut against the combining step 225; each fixing edge 512 of the mounting groove unit 51 of the third thickness mainboard 5 has two third fixing portions 515 (see Figure 7 、 Figure 10 ), the third fixing portion 515 of each fixing edge 512 can be placed on the second step 224 of the corresponding slide rail module 22 and abut against the combining step 225. That is, the shape of each fixing edge 512 of the mainboard 5 of the first thickness is as follows: Figure 8 As shown, the first fixing portion 513 of each fixing edge 512 is designed to correspond to the second step 224, so that the first fixing portion 513 of each fixing edge 512 is placed on the first step 223 of the corresponding slide rail module 22 and fits against the second step 224, but is not limited to this. In particular, in this embodiment, each fixing edge 512 and the corresponding first fixing portion 513 are at the same height and each fixing edge 512 and the corresponding first fixing portion 513 are marked in different colors (the figure does not show different colors, only the edge lines are used to distinguish them) and present the following Figure 8 The shape of each fixed edge 512 of the second thickness main board 5 and the third thickness main board 5 is as follows: Figure 9 、 10 The design shown in the figure and the combination step 225 can correspond to each other, so that the second fixing portion 514 of each fixing edge 512 is placed on the second step 224 of the corresponding slide rail module 22 and fits against the combination step 225, but is not limited to this. In particular, in this embodiment, each fixing edge 512 and the corresponding second fixing portion 514 are at the same height and each fixing edge 512 and the corresponding second fixing portion 514 are marked in different colors (the figure does not show different colors, only the edge lines are used to distinguish them) and present a pattern as shown. Figure 9 The aspects shown are, but not limited to.

[0036] Incidentally, in this embodiment, a locking unit 3 is further included for securing the motherboard 5 to be coupled to the frame unit 2. The locking unit 3 has a plurality of locking members 31 that are detachably locked into the coupling steps 225 of the coupling seat 222 of the rail module 22 and are used to position the motherboard 5 to be coupled to the coupling seat 222, but the present invention is not limited thereto.

[0037] In addition, it is particularly worth mentioning that in this embodiment, a snap unit 4 is also included. One of the rail modules 22 of the frame unit 2 further has a snap slot 226 extending through the top surface of the rail body 221, and two snap members 227 located on opposite sides of the snap slot 226 and extending upward from the top surface of the rail body 221.
