Description

[0001] This application is a divisional application. The application number of the original application is 202210132841.2, and the original application date is February 14, 2022. The entire content of the original application is incorporated into this application by reference. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to a connector assembly and an electronic device. Background Art

[0003] In order to provide customers with more flexible customized services, the server will configure multiple server models for a server motherboard. Different server models have different input and output (IO) device configurations. Considering that the number of slots on the server motherboard is fixed, different types of riser cards (also known as adapter cards) are used to match different types of IO devices, such as network cards and smart network cards, to meet the IO device configuration requirements of different server models.

[0004] As server computing power continues to increase, server I / O resources are constantly increasing. How to fully utilize server I / O resources and expand them to more I / O devices has become a key competitive advantage in server design. Current server designs typically utilize I / O resources by plugging in hard-wired adapter modules. This solution wastes I / O resources due to slot limitations and I / O device form factors. Therefore, providing more I / O slots within a standard-sized server chassis to accommodate more I / O devices is a pressing issue. Summary of the Invention

[0005] The present application provides a connector assembly and an electronic device, which can provide more IO slots in a standard-sized server frame to plug in more IO devices.

[0006] In a first aspect, the present application provides a connector assembly that can be disposed within a chassis of an electronic device to provide an IO slot for the electronic device to plug in an IO device. The connector assembly includes a circuit board, a connector, and a connecting wire assembly. The circuit board has a first surface and a second surface opposite each other. The connector is disposed on the first surface, and the connector has an IO slot for plugging in an IO device, with an opening of the IO slot located at an end of the connector facing away from the circuit board. The connector may have a first boundary and a second boundary at each end along its length, and the first surface of the circuit board may have a wiring area corresponding to the first boundary and the second boundary, with the wiring area located between the first boundary and the second boundary. The connecting wire assembly is electrically connected to the connector via the circuit board, and the connecting wire assembly includes a first wire assembly extending from the wiring area, thereby reducing the space occupied by the connecting wire assembly on one side of the second surface of the circuit board. The first wire assembly has an outlet segment at one end away from the circuit board, the outlet segment being used to lead to and electrically connect to a mainboard of the electronic device. The outlet segment includes an outlet portion, the projection of the outlet portion on the circuit board falling within the wiring area, and the routing direction of the outlet portion is parallel to the length of the connector. When the above-mentioned connector assembly is plugged into an IO device, the IO device is plugged into the IO slot of the connector, and its plugging direction is equivalent to the height direction of the connector (perpendicular to the first surface), and the wiring area of ​​the first wire group sub-circuit board is led out. Compared with the existing technology, the size of the connecting wire group leading out from the second surface of the circuit board is saved, which is equivalent to reducing the space occupied by the connector assembly in the plugging direction; when the IO device is plugged into the connector, the routing direction of the wire part of the leading segment is parallel to the length direction of the connector, so that the routing of the first wire group can utilize the space between the IO device and the circuit board.

[0007] It can be seen that the connector assembly provided in this application occupies a smaller space and can provide more IO slots in a standard-sized server frame to connect more IO devices, which is equivalent to flexibly utilizing CPU resources according to the form of the connector and IO devices.

[0008] In one possible implementation, the connector in the connector assembly is used to connect an IO device. When the IO device is connected to the connector, the distance between the contour of the lead-out portion on the side away from the first surface and the first surface is less than or equal to the distance between the IO device and the first surface of the circuit board. In one possible implementation, the distance between the contour of the lead-out portion on the side away from the first surface and the first surface is less than or equal to 20 mm, thereby ensuring that the first wire group can be routed through the gap between the IO device and the circuit board 1.

[0009] The structure of the first wire group may be implemented in a variety of ways. Possibly, the first wire group includes a transition section that runs from the wiring area to the outlet section, and the projection of the transition section on the circuit board falls within the wiring area. The transition section can be directly electrically connected to the circuit board in a manner perpendicular to the first surface. Alternatively, the connecting wire group may further include a connecting section connected to the transition section, the projection of the connecting section on the circuit board also falling within the wiring area, and the routing direction of the connecting section can be parallel to the first surface. Specifically, the connecting section can be electrically connected to the circuit board by being attached to the first surface and mounted on the circuit board, or it can be arranged within the thickness space of the circuit board by means of grooves, etc. to electrically connect to the circuit board. The connecting section and the circuit board can be connected via pins.

[0010] In one possible implementation, the connection section is arranged perpendicular to the length of the connector. In another possible implementation, the transition section is arranged in an arc shape. Of course, there are other possible implementations for the transition section and the connection section.

[0011] In one possible implementation, a plurality of connecting wire groups are provided along the length direction of the connector, so that the outgoing wire segment includes a plurality of sub-outgoing wire segments, and along the width direction of the connector, the plurality of sub-outgoing wire segments are stacked in sequence in a stepped shape.

[0012] On the second aspect, the present application also provides an electronic device, which can specifically be a server, which includes a machine frame, a motherboard and any one of the connector assemblies provided by the above technical solution; the motherboard and the connector assembly are arranged in the machine frame, and the outgoing line segment of the connecting wire group is electrically connected to the motherboard. When the IO device is plugged into the connector of the connector assembly, the connecting wire group can realize communication between the IO device and the motherboard. When the electronic device includes an IO device, the IO device is plugged into the connector of the connector assembly. The IO device here can be any one of a PCIe (peripheral component interconnect express) card, an NVLink card, and an HCCS (high capacity communication system) card.

[0013] In a possible implementation, the chassis includes a riser card structure, and the connector assembly can be fixed to the riser card structure by screws, bonding, or the like. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In the field of communication technology, servers need to be connected to different types of IO devices. As server computing power continues to increase, the IO resources used to connect to IO devices are also expanded. However, due to the size limitations of the chassis, current servers need to provide more IO slots in a standard-sized chassis to connect more IO devices. Figure 1 Taking a connector for plugging in a PCIe card (equivalent to an IO device) on a server in the prior art as an example, one end of the connector has a slot 01 (equivalent to an IO slot) for docking a PCIe card, and the PCIe card plug-in slot 01 can be electrically connected to a circuit board (not shown here) in the connector; at the other end of the connector facing away from the slot 01, a connecting wire 02 for connecting to the motherboard is led out from the circuit board, and the connecting wire 02 is in the opposite direction to the slot 01. This way of leading out the connecting wire 02 will occupy the size of the connector along the PCIe card plug-in direction, which restricts the number of expandable PCIe cards inside the server, and thus cannot improve the utilization rate of PCIe resources.

[0036] Based on this, the embodiment of the present application provides a connector assembly and a server to solve the above problems. In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings.

[0037] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to limit the present application. As used in the specification and appended claims of this application, the singular expressions "a", "an", "said", "above", "the", and "this" are intended to also include expressions such as "one or more", unless the context clearly indicates otherwise.

[0038] References to "one embodiment" or "some embodiments" in this specification mean that a particular feature, structure, or characteristic described in conjunction with that embodiment is included in one or more embodiments of the present application. Thus, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in yet other embodiments" appearing in various places in this specification do not necessarily refer to the same embodiment, but rather mean "one or more but not all embodiments," unless otherwise specifically emphasized. The terms "including," "comprising," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0039] Please refer to Figure 2a , an embodiment of the present application provides a structural schematic diagram of a connector assembly 10, which can be fixed to an electronic device such as a server when in use, as a structure for the electronic device to plug in an IO device. The connector assembly 10 specifically includes a circuit board 1, a connector 2 and a connecting wire group 3. The circuit board 1 has a first surface p1, and the connector 2 is arranged on the first surface p1. The connector 2 is a long strip structure, and the length direction of the connector 2 is set to X, the width direction is set to Y, and the height direction is set to Z. An IO slot K for plugging in an IO device is formed in the height direction (i.e., the Y direction) of the connector 2. When plugging in an IO device, the IO device is plugged into the IO slot K on the connector 2 along the height direction (i.e., the Y direction) of the connector 2. The opening of the IO slot K is located at the end of the connector 2 away from the first surface p1. The connecting wire group 3 is electrically connected to the connector 2 through the circuit board 1. Specifically, the connecting wire group 3 includes a first wire group 3a extending from the first surface p1.

[0040] The connector 2 and the first wire group 3a are equivalent to being arranged on the first surface p1 of the circuit board 1, and the circuit board 1 provides bearing and support for the connector 2 and the first wire group 3a; wherein, the connector 2 is arranged on the first surface p1 of the circuit board 1, which means that the connector 2 is installed from the first surface p1 of the circuit board 1, so that the opening of the IO slot K of the connector 2 is located on the side of the first surface p1; when the IO device is plugged into the IO slot K, its plugging direction is perpendicular to the first surface p1.

[0041] Among them, the first wire group 3a can specifically include an outgoing wire segment 31 and a transition segment 32. The outgoing wire segment 31 is equivalent to the part of the first wire group 3a away from one end of the circuit board 1, which is used to lead to the mainboard of the electronic device and be electrically connected to it. The transition segment 32 is used to route from the first surface p1 (within the wiring area R) of the circuit board 1 to the outgoing wire segment 31.

[0042] Figure 2bA top view of connector assembly 10 is shown. Along the length of connector 2, connector 2 has a first boundary L1 and a second boundary L2, respectively. First boundary L1 runs perpendicularly through one end of connector 2, while second boundary L2 runs perpendicularly through the other end. Corresponding to first boundary L1 and second boundary L2, first surface p1 has a routing area R (shaded area) for routing the first wire group 3a. The routing area R is used to route the wires from first wire group 3a. The routing area 31 includes a lead-out portion 31a and a lead-out portion 31b. The projection of lead-out portion 31a onto circuit board 1 falls within routing area R, while lead-out portion 31b is used to route the wires to the electronic device's motherboard. Lead-out portion 31b is located between transition section 32 and lead-out portion 31b. The routing direction of lead-out portion 31a is parallel to the length of connector 2, facilitating the use of space between circuit board 1 and the IO device plugged into connector 2.

[0043] The outgoing portion 31b needs to extend out of the circuit board to lead to the mainboard of the electronic device and be electrically connected thereto. The routing direction of the outgoing portion 31b is not limited and can be consistent with the routing direction of the outgoing portion 31a (e.g. Figure 2b Other routing directions are also possible. Here, the routing path of transition section 32 is shown as an arc, and transition section 32 is electrically connected to connector 2 via circuit board 1. It should be understood that the routing path of transition section 32 may also have other shapes, which are not further described here. The connection between transition section 32 and circuit board 1 may be via structures such as solder pads and terminal blocks, which are not further illustrated here.

[0044] Specifically, the portion of the first wire assembly 3a used to connect to the circuit board 1 (equivalent to the area where the transition section 32 exits the circuit board 1) is located within the routing area R, electrically connecting the connecting wire assembly 3 to the connector 2 via the circuit board 1. Along the Y direction, the arrangement of the connecting wire assembly 3 and the connector 2 must not exceed the size of the circuit board 1.

[0045] Combine Figure 2c In the left view of connector assembly 10 shown, wire segment 31 is parallel to the length direction (i.e., the X direction) of connector 1. The distance h between the outermost contour of guide portion 31a of wire segment 31, facing away from first surface p1, and first surface p1 is set. When an IO device is plugged into connector 2, the gap between guide portion 31a of wire segment 31 and circuit board 1 provides space for routing. Therefore, h should be less than or equal to the gap between the IO device and circuit board 1 after the IO device is plugged into connector 2. Based on the current specifications of connector 2 and IO device, h is less than or equal to 20 mm.

[0046] Depend on Figure 2cIt can be seen that the circuit board 1 is a plate-like structure and also has a second surface p2 opposite to the first surface p1. The second surface p2 is used to be installed in the frame of the electronic device. The first surface p1 and the second surface p2 are defined relative to the thickness direction (i.e., the Z direction) of the circuit board 1. The connector 2 is installed from the first surface p1 of the circuit board 1 so that the opening of the IO slot K of the connector 2 is located on the side of the first surface p1. The first wire group 3a is equivalent to being located on the side of the first surface p1 of the circuit board 1 and does not occupy the size of the side of the circuit board 1 away from the second surface p2. Figure 1 The prior art shown is beneficial for reducing the size of the entire connector assembly 10 in the thickness direction of the circuit board 1 .

[0047] In some embodiments, as Figure 2d As shown, the connecting wire group 3 may further include a small amount of second wire groups 3b led out from the second surface p2. Since the larger amount of first wire groups 3a are led out from the wiring area R, the small amount of second wire groups 3b will not have a significant impact on the size of the connector assembly 10 in the thickness direction of the circuit board 1. In other embodiments, such as Figure 2e As shown, the first line group 3a may further include a third line group 3c, and the third line group 3c extends from other areas of the first surface p1 except the wiring area R; Figure 2e In the figure, the third line group 3c extends from the left side of the second boundary L2. Of course, the third line group 3c can also extend from the right side of the first boundary L1 or other non-wiring areas R, which will not be illustrated in the figures here.

[0048] In some embodiments, as Figure 3 The structure of a first wire group 3a is shown. The first wire group 3a is composed of multiple parallel wires. Specifically, the wiring can be arranged in a scheme of ×2 / 4 / 8 / 16 (referring to the signal channel). In the specific implementation, a series design can be performed. The first wire group 3a is divided into different structural areas. The first wire group 3a includes an output segment 31 connected end to end, a transition segment 32, and a connecting segment 33. The connecting segment 33 is used to connect the transition segment 32 to the circuit board 1. At least the lead-out portion 31a of the output segment 31 is arranged in a direction parallel to the X direction ( Figure 3 The routing direction of the outgoing wire segment 31 shown in the figure is parallel to the X direction), and the multiple wires are arranged along the Z direction; the routing direction of the connecting segment 33 is parallel to the first surface p1, and the multiple wires are arranged along the X direction; the transition segment 32 is routed along an arc, and its routing path is an arc, and the multiple wires in the transition segment 32 and the multiple wires in the outgoing wire segment 31 are located in the same plane.

[0049] Please refer to Figure 4aIn the connector assembly 10 shown, along the X direction, the connecting wire group 3 includes multiple sub-outgoing wire segments 311, and the multiple sub-outgoing wire segments 311 are stacked in a stepped manner. Such a structure facilitates the arrangement of the outgoing wire segments 31. Of course, each outgoing wire segment 311 corresponds to a transition segment 32, and some outgoing wire segments 311 and transition segments 32 correspond to the same connecting segment 33. It should be understood that the division of the outgoing wire segments 31, transition segments 32 and connecting segments 33 of the first wire group 3a connecting wire group 3 is based on the routing structure of the first wire group 3a and does not involve the specific connection structure of the connecting wire group 3. Figure 4b In the exploded view of the connector assembly 10 shown, the free end of the connecting section 33 for connecting to the circuit board 1 has a pin 4 , and the connecting section 33 is electrically connected to the circuit board 1 through the pin 4 .

[0050] Combine Figure 5a The top view of the connector assembly 10 is shown and Figure 5b In the left view of the connector assembly 10 shown, the outgoing line segments 31 in each connecting line group 3 are exemplified as having an overall routing direction parallel to the X direction, the routing direction of the connecting segments 33 are exemplified as being perpendicular to the length direction (i.e., the X direction) of the connector 2, and the routing direction of the transition segment 32 is exemplified as being located in the same plane as the routing direction of the outgoing line segments 31. Along the width direction (i.e., the Y direction) of the connector 2, from the first boundary L1 to the direction of the first boundary L2, the distance between the plurality of sub-outgoing line segments 311 and the connector 2 gradually decreases. The connecting segment 33 is arranged on the circuit board 1 in a manner of being attached to the first surface p1 of the circuit board 1, and the connecting segment 33 is electrically connected to the circuit board 1 through the pin 4. It should be understood that Figure 5a The routing method of the connecting section 33 in the connector assembly 10 shown is the shortest straight-line distance between the transition section 32 and the connector 2; of course, the connecting section 33 can also be routed in other ways, such as oblique (forming an angle with the X direction), arc, irregular routing, etc., as long as it can be achieved from the circuit board 1 to the transition section 32.

[0051] In some embodiments, as Figure 6 As shown, a avoidance groove M can be provided on the circuit board 1. The avoidance groove M is located on one side of the length direction of the circuit board 1, and the opening is located at the edge of the side of the circuit board 1. The avoidance groove M is used to accommodate the connecting section 33 of the connecting wire group 3. Figure 7a FIG. 1 shows a top view of a connector assembly 10 having a circuit board 1 of this structure, wherein the connecting section 33 is accommodated in the avoidance groove M. Figure 7b It shows Figure 7a From the cross-sectional structural diagram at the AA position, it can be seen that the connecting section 33 of the connecting wire group 3 is equivalent to being accommodated in the thickness space of the circuit board 1, and does not occupy the space on the side of the second surface p2 of the circuit board 1, which is beneficial for the connector assembly 10 to reduce the volume in the thickness direction of the circuit board 1.

[0052] In the structure of the connecting wire group 3 illustrated in the above embodiment, the routing direction of the transition section 32 and the routing direction of the outlet section 31 are located in the same plane, which is perpendicular to the first surface p1. Possibly, the transition section 32 can also be a three-dimensional structure, and the plane where the transition section 32 is located forms an angle with the length direction (i.e., the X direction) of the connector 2, and also forms an angle with the height direction (i.e., the Z direction) of the connector 2. It should be understood that the specific structure of the connecting wire group 3 can be implemented in a variety of ways, and each part of the structure can also have a variety of shapes, but it is necessary to ensure that the entire connecting wire group 3 is located between the IO device plugged into the connector 2 and the circuit board, and that the routing direction of the guide portion 31a in the outlet section 31 is parallel to the length direction (i.e., the X direction) of the connector 2.

[0053] by Figure 4a As an example of the connector assembly 10 shown in FIG. 1 , the connector assembly 10 provided in the embodiment of the present application needs to be used as follows: Figure 8 The IO device 5 is shown as docking. The IO device 5 can be a PCIe card, hard drive, or other structure capable of communicating with the server motherboard. The IO device 5 has a gold finger 51 (or other connection terminals) for connecting to the connector 2 of the connector assembly 10. The gold finger 51 can be inserted into the IO slot K of the connector 2 along the height direction of the connector 2.

[0054] Figure 9a and Figure 9b The schematic diagram shows the structure after the IO device 5 and the connector 2 of the connector assembly 10 are plugged in. The gold finger 51 of the IO device 5 is inserted into the IO slot K of the connector 2. The distance between the plane where the gold finger 51 of the IO device 5 is set and the circuit board 1 is set to H. The distance between the outermost edge of the connecting wire group 3 on the side away from the circuit board 1 in the connector assembly 10 and the circuit board 1 is set to h. If h is less than or equal to H, at least part of the connecting wire group 3 can be accommodated between the IO device 5 and the circuit board 1. It can be seen that in the connector assembly 10 provided in the embodiment of the present application, the outlet section 31 of the connecting wire group 3 can be routed using the gap between the IO device and the circuit board 1, which is beneficial to reducing the space occupied by the connector assembly 10 and facilitating the arrangement of more connector assemblies 10 in a limited electronic device. The connector 2 in each connector assembly 10 has an IO slot K for plugging in an IO device. More connector assemblies 10 are equivalent to providing more IO slots K to connect more IO devices, thereby improving the utilization rate of IO resources.

[0055] Based on the structure of the connector assembly 10, the embodiment of the present application also provides an electronic device, which can be a server, a switch, a router, a storage device, etc. When the electronic device is a server, it can be a rack server, a high-density server, and a pod server. Figure 10a The rack server shown includes a frame 20, a motherboard (not shown here), and any one of the connector assemblies 10 provided in the above embodiments. The motherboard is also disposed in the frame 20. The connector assembly 10 can be fixed in the frame 20 and the outgoing line segment 31 of the connecting line group 3 can be electrically connected to the motherboard through a flat cable or the like. The connector 2 can provide the server with an IO slot K for plugging in IO devices. Specifically, the frame 20 may include an adapter card structure 201, and the connector assembly 10 can be installed and fixed to the adapter card structure 201. The corresponding structure of the adapter card structure 201 and the connector assembly 10 can be referred to. Figure 10b As shown, the circuit board 1 in the connector assembly 10 is fixed to the riser card structure 201 by means of screws, bolts and the like.

[0056] The IO device 5 here can be any one of a PCIe card, an NVLink card, and an HCCS card. Of course, the types of IO devices 5 include but are not limited to the above-mentioned devices.

[0057] In some embodiments, such as Figure 11 As shown, the electronic device may further include a rear window structure 40, which may cooperate with the adapter card structure 30 to form a space for accommodating the connector assembly 10 and the IO device 5. The IO device 5 may be plugged into the connector assembly 10 as shown in FIG. Figure 12 As shown, two connector assemblies 10 are fixed to the riser card structure 30. The connector 2 in each connector assembly 10 forms an IO slot K, corresponding to two IO devices 5. The rear window structure 40 cooperates with the riser card structure 30 to provide support for the connector assembly 10 and the IO device 5.

[0058] Please refer to Figure 13 An electronic device is shown, comprising a chassis 20 having multiple installation spaces J (shown by dashed lines) within the chassis 20. Each installation space J corresponds to a corresponding riser card structure 201. For any installation space J, depending on the size of the installation space J, the riser card structure 201 can secure multiple (one, two, three, or even more) connector structures 10, which can be connected to multiple (one, two, three, or even more) IO devices.

[0059] In combination with the structure of the connector assembly 10 in the above embodiment, the connector assembly 10 has a small volume and occupies less space in the frame 20. The size of the frame 20 is a standard size in the industry, and more connector assemblies 10 can be arranged in the frame 20, so that the server can plug in more IO devices.

[0060] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
