[0002] In an existing 2U small chassis, if it is necessary to interconnect any two boards in the chassis, the traditional method is to connect them through external cables to enable communication between the two boards.

[0003] However, the method of connecting the board card through an external cable usually has the following problems: an opening needs to be made in the input and output bracket (IO bracket) area of ​​the chassis, and the external cable with one end connected to the board card is first led to the outside of the chassis through the opening, and then introduced into the inside of the chassis through another opening to connect to another board card. This causes the original IO bracket area to be occupied, which largely blocks the air inlet channel of the chassis vent and reduces the heat dissipation performance, so that only boards with lower power consumption and performance can be used for combination, thereby reducing the power consumption and performance of the whole product and reducing the competitiveness of the whole machine.

[0027] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described clearly and completely in conjunction with the drawings in the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The following describes the soft-hard combined board-card connection assembly and chassis of the present invention in conjunction with the accompanying drawings.

[0029] Figure 1 This is one of the structural schematic diagrams of the soft-hard combined board-card connection assembly provided by the utility model, such as Figure 1 As shown, Figure 1 It is a side view of a hard-soft combined board-card connection assembly, the hard-soft combined board-card connection assembly 100 comprises: a flexible electrical connection board 101, at least two rigid electrical connection boards 102 and a SLOT connector 103;

[0030] It should be noted that Figure 1 In the figure, a hard-soft combined board-to-board connection assembly 100 including a flexible electrical connection board 101, two rigid electrical connection boards 102 and two SLOT connectors 103 is taken as an example for illustration.

[0031] Among them, the at least two rigid electrical connection boards are arranged on the flexible electrical connection board, and at least one SLOT connector is arranged on each of the at least two rigid electrical connection boards. The at least two rigid electrical connection boards are electrically connected to the flexible electrical connection boards and each SLOT connector respectively, and each SLOT connector is used to connect to the board.

[0032] It should be noted that the soft-hard board connection assembly provided by the present invention is used to connect different boards in a chassis to achieve interconnection between different boards.

[0033] In the related art, in order to realize interconnection between two cards in an existing 2U small chassis, external cables are usually used for interconnection communication; wherein U represents the standard height of the chassis.

[0034] The above-mentioned method of using external cables (such as high-speed cables) for interconnection and communication between boards has the following defects:

[0035] 1) Use external cables for inter-board communication. Multiple external cables will greatly affect the appearance and take up additional space in the computer room.

[0036] 2) The IO bracket area will be occupied by the connected cables, which will largely block the air inlet of the chassis vents, reduce the heat dissipation performance, and thus reduce the power consumption and performance of the product.

[0037] In view of the above problems, the present invention finds that the reason why the existing method of realizing interconnection and communication between boards through openings in the IO bracket area and using external cables is that: the size of a 2U chassis is small, and the space is compact after the internal devices are set up, making it difficult to interconnect the internal boards of the chassis.

[0038] On this basis, an embodiment of the utility model provides a soft-hard combined board-card connection component, including a flexible electrical connection board, at least two rigid electrical connection boards and a SLOT connector. Specifically, at least two rigid electrical connection boards are arranged on the flexible electrical connection board, and each rigid electrical connection board is provided with at least one SLOT connector. The SLOT connector can be electrically connected to the SLOT connector on another rigid electrical connection board through the rigid electrical connection board and the flexible electrical connection board in sequence, and the SLOT connector is used to connect to the board, so any board can be connected to the SLOT connector of the board connection component, and then connected to another board through another SLOT connector of the board connection component, thereby realizing interconnection between boards.

[0039] Optionally, the flexible electrical connection board may be realized by, for example, a flexible (bendable) printed circuit board (PCB board).

[0040] Figure 2 This is the second structural diagram of the soft-hard combined board-card connection component provided by the utility model, such as Figure 2 As shown, Figure 2 This is a top view of a soft-hard combined board connection assembly. It should be noted that the specific position of the rigid electric connection board on the flexible electric connection board can be flexibly set according to the relative position relationship between the two boards to be connected. For example, the two rigid electric connection boards can be set on the same plane of the flexible electric connection board, or they can be set on different planes respectively. The specific distance between the two rigid electric connection boards can also be set according to actual conditions. In addition, the specific position of the SLOT connector on the rigid electric connection board can also be set according to actual conditions.

[0041] In the soft-hard combined board-card connection assembly provided by the embodiment of the utility model, compared with the related art that it is difficult to realize the interconnection between boards due to the small internal connection space of the chassis, and the board-card interconnection is realized through external cables, the soft-hard combined board-card connection assembly of the utility model can be bent and connected through a flexible electrical connection plate, and the rigid electrical connection plate is used to fix the SLOT connector on the flexible electrical connection plate to connect with the board-card, and the interconnection between boards can be realized inside the chassis when the internal connection space of the chassis is small. Therefore, there is no need to make an opening in the IO bracket area of ​​the chassis and realize the interconnection between boards through external cables, which effectively alleviates the problem of external cables blocking the air inlet channel of the chassis vent, improves the heat dissipation performance, and then improves the power consumption and performance of the product, and improves the competitiveness of the whole machine.

[0042] Optionally, each of the SLOT connectors may be provided with at least one slot, and each of the slots is used to be connected to the board.

[0043] Optionally, each of the slots is specifically used to be connected to at least one plug-in gold finger provided on the board.

[0044] Specifically, some boards may need to be connected through multiple interfaces. In related technologies, it is usually necessary to add multiple external interfaces to the internal boards, and the multiple external interfaces need to be connected to other internal boards through external cables. Figure 3 It is a schematic diagram of the structure of the internal board in the related technology, such as Figure 3 As shown, Figure 3 The example of adding three extended external interfaces on the internal board is used to illustrate that the cost of setting up the interface is relatively high, and connecting the boards through multiple external cables will greatly affect the appearance and occupy additional space in the computer room. In addition, multiple external cables will also block the air inlet channel of the chassis vents, reducing the heat dissipation performance of the chassis, thereby reducing the power consumption and performance of the product.

[0045] In response to the above problems, in the embodiment of the utility model, at least one slot can be provided on each SLOT connector, and these slots can be used to connect with the plug-in gold fingers set on the board to support the interconnection between internal boards with multiple interfaces without setting up multiple connection components for separate connections, further saving the internal space of the chassis occupied by the board connection, which is beneficial to improving the heat dissipation performance of the chassis.

[0046] For example, for a board connected via three interfaces, the SLOT connector can be set to include three slots, and three plug-in gold fingers can be set accordingly on the board. The three slots and the three plug-in gold fingers need to be set accordingly so that all slots and the plug-in gold fingers can be connected normally.

[0047] It should be noted that the present invention does not limit the number of slots set on the SLOT connector, as long as the number of slots is compatible with the number and size of the plug-in gold fingers on the board to be connected, the number of slots on multiple SLOT connectors set on the same soft-hard combined board connection component can be the same or different.

[0048] Optionally, the at least two rigid electrical connection plates may include a first rigid electrical connection plate and a second rigid electrical connection plate, and the first rigid electrical connection plate and the second rigid electrical connection plate are respectively arranged at two ends of the flexible electrical connection plate.

[0049] Specifically, Figure 1 and Figure 2 As shown, the rigid electrical connection plate on the left can be considered as the first rigid electrical connection plate, and the rigid electrical connection plate on the right can be considered as the second rigid electrical connection plate. The first rigid electrical connection plate and the second rigid electrical connection plate are respectively arranged at both ends of the flexible electrical connection plate, which can save the internal space of the chassis occupied by the board connection while ensuring the connection between the boards, which is beneficial to improving the heat dissipation performance of the chassis.

[0050] The embodiment of the utility model further provides a chassis, comprising: at least two boards and at least one board connection assembly combining soft and hard components as described in any of the above embodiments;

[0051] Wherein, each of the soft-hard combined board-card connection components is used to connect any two boards among the at least two boards.

[0052] Optionally, the chassis may be a 2U chassis.

[0053] Specifically, the soft-hard combined board-card connection assembly provided by the embodiment of the utility model is more suitable for a 2U chassis, which has a smaller space and more compact components, but is not limited to being used in a 2U chassis.

[0054] Optionally, each of the boards is provided with at least one plug-in golden finger, and each of the plug-in golden fingers is used to be connected to a SLOT connector in each of the soft-hard combined board connection components.

[0055] Specifically, the utility model provides at least one plug-in gold finger on the board in the chassis to replace the external interface provided to the board in the related art. The plug-in gold finger is used to connect to the corresponding SLOT connector in the soft-hard board connection component to realize the connection between the boards through the soft-hard board connection component.

[0056] Optionally, the chassis may further include an IO bracket;

[0057] The opening direction of the IO bracket is perpendicular to the boards, and the plugging and unplugging direction of each plugging and unplugging gold finger is perpendicular to the opening direction of the IO bracket.

[0058] Specifically, Figure 4 It is a schematic diagram of the structure of the internal board in the chassis provided by the utility model, such as Figure 4 As shown, the chassis also includes an IO bracket, and the opening direction of the IO bracket is set perpendicularly between the boards. The figure takes a board as an example. When setting the plug-in gold finger, its plug-in direction can be set perpendicular to the opening direction of the IO bracket.

[0059] The following examples illustrate the hardware-software combined board-to-card connection assembly and chassis provided in the embodiments of the present invention.

[0060] The embodiment of the utility model adopts a soft-hard combined board structure to enable the interconnection between the two cards to be directly realized inside the chassis.

[0061] Specifically, firstly, the internal boards of the chassis do not need to add an on-board connector interface (external interface), and a plug-in gold finger design can be adopted, and the direction of the gold finger can be perpendicular to the IO bracket.

[0062] In addition, the utility model designs a hard-soft combination board (hard-soft combination board connection component) with two high-speed SLOT connectors connected to the gold finger, wherein the two ends of the board are rigid electrical connection boards with SLOT, and the middle is a flexible electrical connection board, such as a bendable flexible PCB board.

[0063] Figure 5 It is a schematic diagram of the assembly sequence of the chassis provided by the utility model, such as Figure 5 As shown, during assembly, two internal boards can be connected together using a soft-hard board connection component (1→2), and then assembled into a chassis as a whole (2→3).

[0064] After a high-speed SLOT connector is attached or welded to the rigid electrical connection board of the soft-hard board connection assembly, the two internal boards are first connected into a whole through the soft-hard board connection assembly, and then assembled into the chassis. This assembly method connected through the soft-hard board connection assembly has at least the following advantages:

[0065] 1) Multiple connection interfaces can be directly connected through a soft-hard board connection component, avoiding the extra assembly space occupied by the assembly of multiple external cables;

[0066] 2) Only two SLOT connectors are needed, and slots adapted to the plug-in and pull-out gold fingers are set on the SLOT connectors. There is no need to add additional SLOT connectors due to the increase in the number of board interfaces, and the design is simple and convenient;

[0067] 3) There is no need to design an opening for the IO Bracket and occupy the air inlet channel of the chassis, thereby affecting the overall heat dissipation effect of the chassis. The utility model can effectively improve the performance of the entire machine.

[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
