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 configuration standards that comply with the OCP (Open Compute Project) NIC 3.0 are now commonly used. Generally speaking, a connector of a connection frame set on the motherboard is used to connect the network card and the network card is electrically connected to the motherboard through the connector. However, in order to meet the standard design requirements of OCP NIC 3.0, the height of the connector of the connection frame set for motherboards of different thicknesses will be slightly different, so it is necessary to open a connection frame specifically corresponding to the motherboard to be combined according to the motherboards of different thicknesses, that is, the connectors of the connection frames of motherboards of different thicknesses cannot support and share each other, the overall applicability is poor and causes inconvenience in the assembly and manufacturing process. Therefore, how to design a frame that can support the combination of multiple motherboards of different thicknesses and enable the motherboard to be electrically connected to the network card is worthy of further discussion and improvement by practitioners.

Each mounting groove unit has a connecting edge and two fixed edges extending from two opposite ends of the connecting edge in a direction away from the connecting edge. The network card combination device is combined with one of the motherboards and includes a frame unit installed in the mounting groove unit of the motherboard and capable of combining with the network card. The frame unit includes a connection frame module that is combined with the connecting edge of the mounting groove unit, and two slide rail modules that extend from two 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.

Each rail module has a rail body connected to the connection frame module, and two coupling seats spaced apart on the rail body and extending from the rail body in a direction away from the installation space and used to support the fixed edge. Each coupling seat of each rail module has 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 mainboard combined with the network card combining device is a first thickness, the fixed edge of the mainboard 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 mainboard 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 mainboard; when the thickness of the mainboard combined with the network card combining device is a second thickness less than the first thickness, the fixed edge of the mainboard is placed on the second step of the slide rail module of the frame unit and fixed on the second step.

[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 also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The network card combination device 1 of the present invention can support a network card 6 to be installed on a plurality of different types of motherboards 5. Each motherboard 5 includes a mounting groove unit 51 that is combined with the network card combination device 1. Each mounting groove unit 51 has a connecting edge 511 and two fixing edges 512 extending from two opposite ends of the connecting edge 511 in a direction away from the connecting edge 511. The network card combination device 1 is combined with one of the motherboards 5, and includes a frame unit 2 that is installed in the mounting groove unit 51 of the motherboard 5 and can be combined with the network card 6.

[0029] The frame unit 2 includes a connection frame module 21 combined with a connection edge 511 of the installation groove unit 51, and two slide rail modules 22 extending from two opposite ends of the connection frame module 21 in a direction away from the connection frame module 21 and corresponding to the fixed edge 512 of the installation groove unit 51. The connection frame module 21 has a connection slot 211 electrically connected to the motherboard 5 and capable of being plugged and connected to the network card 6. The two opposite ends of the network card 6 can be inserted into the slide rail module 22 and can move relative to the slide rail module 22 toward the connection frame module 21. The slide rail module 22 and the connection frame module 21 together define an installation space 23 for accommodating the network card 6.

[0030] Each rail module 22 has a rail body 221 connected to the connection frame module 21, and two coupling seats 222 spaced apart from each other on the rail body 221 and extending from the rail body 221 in a direction away from the installation space 23 and used to support the fixed edge 512. Each coupling seat 222 of each rail module 22 has 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 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 combined by the network card combination device 1 is a second thickness less than the first thickness, the fixed edge 512 of the motherboard 5 to be combined is placed on the second step 224 of the rail module 22 of the frame unit 2 and fixed on the second step 224, at this time, the connection edge 511 of the installation 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 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 thickness of the motherboard 5 is the first thickness, the fixed edge 512 of the motherboard 5 is placed on the first step 223 of the coupling 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 less than the first thickness, in order to make the connecting edge 511 of the mounting groove unit 51 of the second thickness of the motherboard 5 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 bonding 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 of the 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 correction value of 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, 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 it 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 that the connecting edge 511 of the installation 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 lower than the network card 6 by 0.3 mm. Therefore, in this embodiment, the second step 224 of the coupling seat 222 of the slide rail module 22 of the frame unit 2 is designed to be able to accommodate the fixed edge 512 of the motherboard 5 with a thickness of 1.93 mm, and 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 slide rail module 22 of the frame unit 2, the connecting edge 511 of the installation 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 lower than the network card 6 by 0.3 mm. Relatively speaking, due to the OCP NIC According to the design requirements of the 3.0 specification, the motherboard 5 with a thickness of 2.36 mm needs to be electrically connected to the connection edge 511 of the mounting groove unit 51 and 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 design of the network card 6. However, if the motherboard 5 with a thickness of 2.36 mm 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 motherboard 5 with a thickness of 2.36 mm cannot be aligned with the network card 6 due to the thickness difference. Therefore, in this embodiment, the connection seat 222 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 combination seat 222 is lower than the second step 224 and has a height difference of 0.515mm, so that the first step 223 of the combination seat 222 can be placed on the fixed edge 512 of the motherboard 5 with a thickness of 2.36mm, and when the fixed edge 512 of the motherboard 5 with a thickness of 2.36mm is placed on the first step 223 of the slide rail module 22 of the frame unit 2, the connection edge 511 of the installation groove unit 51 of the motherboard 5 with a thickness of 2.36mm 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, but it is not limited to this. In simple terms, the second step 224 of each combination seat 222 and the corresponding first step 223 are stepped with a height difference of 0.515mm, and the installation requirements of supporting the required combination motherboard 5 with a thickness of 1.93mm or 2.36mm can be achieved, but it is not limited to this.

[0033] The combination seat 222 of the slide rail module 22 of the frame unit 2 can accommodate the fixed edge 512 of the mounting groove unit 51 of the motherboard 5 to be combined, and the first step 223 of each combination seat 222 and the corresponding second step 224 are designed to be stepped, so that the thickness of the motherboard 5 to be combined can be met. The fixed edge 512 of the motherboard 5 of the first thickness is placed and fixed on the first step 223, so that the connection edge 511 of the mounting groove unit 51 of the motherboard 5 can be connected with the motherboard 5. The connection slot 211 of the frame unit 2 is electrically connected to ensure that the network card 6 is plugged into the connection slot 211 and 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 the connection slot 211 and 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 Fig.10In this embodiment, when the thickness of the motherboard 5 to be combined with the network card combination device 1 is a third thickness less than the second thickness, the fixed edge 512 of the motherboard 5 to be combined 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 installation groove unit 51 of the motherboard 5 is electrically connected to the connection slot 211 of the frame unit 2, and 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. For example, in this embodiment, the third thickness is 1.57 mm, but it is not limited thereto. That is to say, the present 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 with the third thickness, since the third thickness is also smaller than the first thickness, in order to enable the connection edge 511 of the mounting groove unit 51 of the motherboard 5 with the third thickness to be electrically connected to the connection slot 211 of the frame unit 2, the fixed edge 512 of the motherboard 5 is placed on the second step 224 of the bonding 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 connection edge 511 of the motherboard 5 with the third thickness is aligned with the connection slot 211 of the frame unit 2 and the connection edge 511 of the motherboard 5 can be smoothly electrically connected to the connection slot 211 of the frame unit 2. The center of the connection edge 511 of the motherboard 5 is aligned with the network card 6, which meets the standard design requirements of OCP NIC 3.0. Finally, the assembly is completed by inserting the two opposite ends of the network card 6 into the rail module 22 and moving along the rail module 22 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. In particular, the motherboard 5, the network card 6, and the network card combination device 1 combined with the motherboard 5 can be combined into a motherboard system. The assembly method is the same as the above-mentioned assembly action and is not further described here.

[0035] In addition, it should be particularly noted that, in this embodiment, each fixing edge 512 of the mounting groove unit 51 of the main board 5 of the first thickness has two first fixing portions 513 (see 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 main board 5 has two second fixing portions 514 (see Figure 6 , Fig. 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 main board 5 of the third thickness has two third fixing portions 515 (see Figure 7 , Fig.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 main board 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 first step 223 of the corresponding slide rail module 22 and fit against the second step 224, but it is not limited to this. In particular, in this embodiment, each fixing edge 512 and the corresponding first fixing portion 513 have the same height and each fixing edge 512 and the corresponding first fixing portion 513 have 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 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: Fig. 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 it is not limited to this. In particular, in this embodiment, each fixing edge 512 and the corresponding second fixing portion 514 have the same height and each fixing edge 512 and the corresponding second fixing portion 514 have different colors (the figure does not show different colors, only the edge line is used to distinguish them) and present a marking state as shown in the figure. Fig. 9 The aspects shown are not limited thereto.

[0036] Incidentally, in this embodiment, a locking unit 3 is further included for fixing the motherboard 5 to be combined on the frame unit 2.
