[0002] CPCI blade cards typically refer to boards that conform to the CPCI (CompactPCI) standard and are widely used in industrial control, communications, aerospace, and other fields. High performance and high reliability: The CPCI bus has high transmission rates and bandwidth, meeting the demands of high-speed data transmission and processing. Its pin-type connectors and robust mechanical structure make the blade cards highly resistant to shock and impact, suitable for harsh environments.
[0003] Currently, to meet different space and interface requirements in various scenarios, CPCI blade cards are mainly applicable to fields such as rail transportation, shipborne, aviation, telecommunications, and industrial measurement and control. Traditional CPCI blade cards have limited functionality, do not include a switch module, have a relatively small number of network ports, and occupy a large amount of space for enclosure mounting. They are difficult to meet the requirements of some space-constrained areas (such as 16HP space) and cannot satisfy some customized needs. Utility Model Content

[0033] Please see Figures 1 to 3 This embodiment provides a CPCI knife card assembly, which includes a heat sink 1, a switch daughter card 2, a main function card 3, a motherboard 4, a network and serial port daughter card 6, an adapter cable 7, and a panel 85.
[0034] in,
[0035] The radiator 1 is arranged to extend along the first direction as a whole;
[0036] The spacing between the switch sub-card 2 and the heat sink 1 is set on one side of the heat sink 1. The switch sub-card 2 extends along a second direction parallel to the first direction, and a first space 9 is formed between the switch sub-card 2 and the heat sink 1.
[0037] The main function card 3 is at least partially disposed in the first space 9, and the main function card 3 is disposed in parallel with the switch sub-card 2 and / or the heat sink 1.
[0038] The motherboard 4 is at least partially disposed in the first space 9, and the motherboard 4 is disposed parallel to the switch daughter card 2 and / or heat sink 1;
[0039] The network and serial port sub-card 6 is connected to the side of the heat sink 1 away from the first space 9;
[0040] The adapter cable 7 connects to the network and serial port sub-card 6 at one end and to the main function card 3 at the other end.
[0041] Panel 85 extends along a third direction, which is orthogonal to at least one of the first and second directions.
[0042] When viewed along the first or second direction, one of the motherboard 4 and the switch daughter card 2 is positioned closer to the heatsink 1.
[0043] When viewed along the first or second direction, the motherboard 4 at least partially overlaps with the first space 9.
[0044] First, it needs to be clarified that in this embodiment, the heat sink 1, switch sub-card, main function card 3, motherboard 4, panel 85, network and serial port sub-cards 6, etc., are technical means known to those skilled in the art, and will not be described in detail in this application. In this embodiment, parallel arrangement means that they are generally parallel to each other, and there can be an angular deviation within 5%. For example, the main function card 3 and the heat sink 1 are arranged in parallel. In this embodiment, it means that the middle symmetrical plane of the main function card 3 is roughly symmetrically bisected and parallel to the roughly symmetrical plane of the heat sink 1, and an angular deviation of 5% is allowed between these two symmetrical planes. That is, when there is actually an angular deviation of less than 5% between the two symmetrical planes, they are still referred to as being parallel to each other.
[0045] Secondly, in this embodiment, either the main function card 3 or the motherboard 4 can be installed closer to the heat sink 1. Preferably, when viewed along the first or second direction, the motherboard 4 is installed closer to the heat sink 1 than the main function card 3.
[0046] Furthermore, the installation between the network and serial port daughter card 6 and the heat sink 1 is achieved in the following manner: the heat sink 1 includes a heat dissipation area 14 and an installation area 15. The heat dissipation area 14 is an area including several heat dissipation fins, and the installation area 15 is a flat plate. The network and serial port daughter card 6 can be detachably installed in the installation area 15 of the heat sink 1 through a first connector, which can be a screw.
[0047] Motherboard 4 is mounted on heatsink 1 via a second connector, which is a copper standoff.
[0048] The main function board is mounted on the heatsink 1 and / or the motherboard 4 via a third connector. That is, the main function board can be directly mounted on the heatsink 1 or indirectly connected and fixed to the heatsink 1 by mounting it on the motherboard 4. Figure 2 As shown, the side of the motherboard 4 facing the heatsink 1 is connected to the heatsink 1 via a first copper pillar, the side of the main function board facing the motherboard 4 is connected to the motherboard 4 via a second copper pillar, and a third copper pillar is provided on the side of the main function board away from the motherboard 4. The switch daughter card 2 is fixed to the main function board by connecting the third copper pillar with screw threads.
[0049] The CPCI knife card assembly provided in this embodiment is arranged with the motherboard 4 and main function card 3 distributed in the middle of the heat sink 1 and the switch daughter card 2, and the heat sink 1 assembly with network and serial ports 6 and the switch daughter card 2 distributed on both sides. This layout ensures that the space of the motherboard 4 and heat sink 1 is maximized, while also allowing more functional interfaces to be arranged in the limited 16HP space. It has both main function interfaces and expansion switch board interfaces, and can be flexibly replaced if the switch card is upgraded in the future.
[0050] In a further embodiment, the panel 85 is at least partially disposed outside the first space 9. The panel 85 may be completely located outside the first space 9, or it may extend partially into the first space 9 and partially outside the first space 9. This embodiment preferably adopts the design where the panel 85 extends partially into the first space 9 and partially outside the first space 9.
[0051] The network and serial port sub-card 6 has at least one first interface 10, and the panel 85 is provided with at least one first hole 12 corresponding to the number of first interfaces 10. The first interface 10 can pass through the first hole 12 and extend to the side of the panel 85 away from the first space 9.
[0052] The switch sub-card 2 has at least one second interface 11, and the panel 85 is provided with at least one second hole 13 corresponding to the number of second interfaces 11. The second interface 11 can pass through the second hole 13 and extend to the side of the panel 85 away from the first space 9.
[0053] This design allows the first interface 10 and the second interface 11 to be integrated at panel 85, effectively saving space.
[0054] To facilitate the installation of panel 85 and save installation space, at least one connecting block 16 is provided on the side of panel 85 facing or located in the first space 9. At least one connecting block 16 can be connected to one of the main board 4 and the main function board through a second connector, which is a screw.
[0055] In this embodiment, in order to securely install the panel 85, two connecting blocks 16 and two connecting members are provided, and the two connecting blocks 16 are spaced apart.
[0056] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
