[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, smart network cards, etc., to meet the IO device configuration requirements of different server models.

[0004] As server computing power continues to increase, server IO resources continue to increase. How to fully utilize server IO resources to expand to more IO devices has become a key competitive advantage in server overall design. In current server designs, IO resources are usually utilized by plugging IO devices into hard-wired adapter modules. This solution wastes IO resources due to slot limitations and IO device form limitations. Therefore, how to provide more IO slots in a standard-sized server frame to plug in more IO devices is a problem that needs to be solved now. 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 the first aspect, the present application provides a connector assembly, which can be arranged in a frame of an electronic device, and provides 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 group, the circuit board has a first surface and a second surface opposite to each other, the connector is arranged on the first surface, and the connector has an IO slot for plugging in an IO device, and the opening of the IO slot is located at one end of the connector away from the circuit board; wherein, along the length direction of the connector, the two ends of the connector may correspond to a first boundary and a second boundary, and corresponding to the first boundary and the second boundary, the first surface of the circuit board has a wiring area, and the wiring area is located between the first boundary and the second boundary; the connecting wire group is electrically connected to the connector through the circuit board, and the connecting wire group includes a first wire group led out from the above wiring area, which can reduce the space occupied by the connecting wire group on one side of the second surface of the circuit board; the first wire group has an outlet segment at one end away from the circuit board, and the outlet segment is used to lead to the mainboard of the electronic device and electrically connected thereto; the outlet segment includes an outlet portion, and the projection of the outlet portion on the circuit board falls within the wiring area, and the routing direction of the outlet portion is parallel to the length direction 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 prior art, 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 conductor part of the leading wire 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 the present 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 being able to flexibly utilize CPU resources according to the form of the connector and IO devices.

[0008] In a possible implementation, the connector in the connector assembly is used to plug in an IO device when in use. When the IO device is plugged into the connector, the distance between the contour of the lead-out portion 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 a possible implementation, the distance between the contour of the lead-out portion 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 is less than or equal to 20 mm, so as to ensure that the first wire group can be routed in 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, the transition section is routed from the wiring area to the outlet section, and the projection of the transition section on the circuit board falls within the wiring area, and 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 also include a connecting section connected to the transition section, the projection of the connecting section on the circuit board also falls within the wiring area, and the routing direction of the connecting section may be parallel to the first surface; specifically, the connecting section may be electrically connected to the circuit board in a manner of being attached to the first surface and mounted on the circuit board, or the connecting section may be arranged in the thickness space of the circuit board by means of grooving or the like to be electrically connected to the circuit board. Among them, the connecting section and the circuit board may be connected by pins.

[0010] In one possible implementation, the routing direction of the connecting section is perpendicular to the length direction of the connector; in another possible implementation, the routing direction of the transition section is arc-shaped. Of course, there may be other possible implementations of the routing of the transition section and the connecting section.

[0011] In a possible implementation, a plurality of connection line groups are provided along the length direction of the connector, so that an outgoing line segment includes a plurality of sub-outgoing line segments, and along the width direction of the connector, the plurality of sub-outgoing line 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 mainboard and any one of the connector assemblies provided by the above technical solution; the mainboard 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 mainboard. 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 mainboard. 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 a HCCS (high capacity communication system) card.

[0013] In a possible implementation, the frame includes an adapter card structure, and the connector assembly can be fixed to the adapter card structure by means of 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 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 Take 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. 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. 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, restricting the number of expandable PCIe cards inside the server, and thus failing to 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 in conjunction with the accompanying drawings.

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

[0039] Please refer to Figure 2a , an embodiment of the present application provides a schematic diagram of the structure of a connector assembly 10, which can be fixed to an electronic device such as a server when in use, as a structure of the electronic device for plugging 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, and 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 thereto, and 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 2bThe top view of the connector assembly 10 is shown. Along the length direction of the connector 2, the two ends of the connector 2 correspond to the first boundary L1 and the second boundary L2 respectively. The first boundary L1 passes through one end of the connector 2 perpendicularly to the length direction of the connector 2, and the second boundary L2 passes through the other end of the connector 2 perpendicularly to the length direction of the connector 2. Corresponding to the first boundary L1 and the second boundary L2, the first surface p1 has a wiring area R (shaded area), and the wiring area R is used to set the first line group 3a outgoing line; wherein the outgoing line segment 31 may include a lead-out portion 31a and an outgoing line portion 31b, the projection of the lead-out portion 31a on the circuit board 1 falls within the wiring area R, and the outgoing line portion 31b is used to lead out the line to the mainboard of the electronic device, and the lead-out portion 31b is located between the transition section 32 and the outgoing line portion 31b. Here, the routing direction of the lead-out portion 31a is parallel to the length direction of the connector 2, which is convenient for using the space between the circuit board 1 and the IO device plugged into the 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 Here, the routing path of the transition section 32 is shown in an arc shape, and the transition section 32 is electrically connected to the connector 2 through the circuit board 1. It should be understood that the routing path of the transition section 32 may also be other shapes, which will not be repeated here. The transition section 32 may be connected to the circuit board 1 through structures such as pads and wiring terminals, which will not be illustrated here.

[0044] Specifically, the portion of the first wire group 3a used to connect to the circuit board 1 (equivalent to the wire exit area of ​​the transition section 32 from the circuit board 1) is located in the wiring area R, so that the connecting wire group 3 is electrically connected to the connector 2 through the circuit board 1. Along the Y direction, the arrangement of the connecting wire group 3 and the connector 2 needs to not exceed the size of the circuit board 1.

[0045] Combination Figure 2c In the left view of the connector assembly 10 shown, the line segment 31 is parallel to the length direction of the connector 1 (i.e., the X direction), and the distance between the outermost contour of the guide portion 31a of the line segment 31 away from the first surface p1 and the first surface p1 is set to h. When the IO device is plugged into the connector 2, the gap between the IO device and the circuit board 1 can be used for the guide portion 31a of the line segment 31 to route. Therefore, h here should be less than or equal to the gap between the IO device and the circuit board 1 after the IO device is plugged into the connector 2. According to the current specifications of the connector 2 and the IO device, h here 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, and 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 here 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 will not occupy the size of the side of the circuit board 1 away from the second surface p2. Compared with Figure 1 The prior art shown is beneficial to reducing the size of the entire connector assembly 10 in the thickness direction of the circuit board 1 .

[0047] In some embodiments, Figure 2d As shown, the connecting wire group 3 may also include a small amount of second wire groups 3b led out from the second surface p2. Since a large amount of the first wire group 3a is led out from the wiring area R, a small amount of the second wire group 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 may also extend from the right side of the first boundary L1 or from other non-wiring areas R, which will not be illustrated in the figures here.

[0048] In some embodiments, 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 wires can be routed in a scheme of ×2 / 4 / 8 / 16 (referring to the signal channel). A series design can be performed during specific implementation. Divided by different structural areas of the first wire group 3a, the first wire group 3a includes an outlet segment 31, a transition segment 32, and a connecting segment 33 connected end to end in sequence. The connecting segment 33 is used to connect the transition segment 32 with the circuit board 1. At least the routing direction of the lead-out portion 31a of the outlet segment 31 is parallel to the X direction ( Figure 3 The routing direction of the outgoing line segment 31 shown in the figure is parallel to the X direction), and the multiple cables are arranged along the Z direction; the routing direction of the connecting segment 33 is parallel to the first surface p1, and the multiple cables 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 cables of the transition segment 32 and the multiple cables of the outgoing line 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 a plurality of sub-outgoing wire segments 311, which are stacked in a stepped manner in sequence. 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] Combination Figure 5a A 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 illustrated as having an overall routing direction parallel to the X direction, the routing direction of the connecting segments 33 are illustrated as being perpendicular to the length direction of the connector 2 (i.e., the X direction), and the routing direction of the transition segment 32 is illustrated as being located in the same plane as the routing direction of the outgoing line segments 31. Along the width direction of the connector 2 (i.e., the Y direction), from the first boundary L1 to the direction pointing to 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 disposed 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 other routing methods, 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, 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 connection section 33 of the connecting wire group 3, Figure 7a FIG. 1 shows a top view of a connector assembly 10 having such a circuit board 1. At this time, the connecting section 33 is accommodated in the avoidance groove 24. 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, and the plane 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., X direction) of the connector 2, and also forms an angle with the height direction (i.e., 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 the routing direction of the guide part 31a in the outlet section 31 is parallel to the length direction (i.e., X direction) of the connector 2.

[0053] by Figure 4a As an example, the connector assembly 10 shown in FIG. 1 is used as an example. Figure 8 The IO device 5 is shown as docking, and the IO device 5 can be a structure such as a PCIe card, a hard disk, etc. that can communicate with the server motherboard. The IO device 5 has a gold finger 51 (or other forms of connection end) for connecting to the connector 2 of the connector assembly 10, and 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 of the structure after the IO device 5 and the connector 2 of the connector assembly 10 are plugged in is shown, 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, and 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, and h is less than or equal to H, so that 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 segment 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 arranging 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, and 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. Fig.10a A rack server shown in the figure includes a frame 20, a mainboard (not shown here) and any one of the connector assemblies 10 provided in the above embodiments. The mainboard is also arranged 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 mainboard through a flat cable, etc. The connector 2 can provide an IO slot K for the server to plug in an IO device. Specifically, the frame 20 may include an adapter card structure 201, and the connector assembly 10 may be installed and fixed on the adapter card structure 201. The corresponding structure of the adapter card structure 201 and the connector assembly 10 can refer to Fig.10b As shown, the circuit board 1 in the connector assembly 10 is fixed to the adapter 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 a HCCS card. Of course, the types of IO devices 5 include but are not limited to the above-mentioned devices.

[0057] In some embodiments, Fig.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. Fig.12 As shown, two connector assemblies 10 are fixed on the adapter card structure 30, and 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 adapter card structure 30 to provide support for the connector assembly 10 and the IO device 5.

[0058] Please refer to Fig.13 An electronic device is shown, the electronic device includes a frame 20, the frame 20 has a plurality of installation spaces J (shown by dotted lines), and each installation space J is provided with a corresponding adapter card structure 201. For any installation space J, according to the size of the installation space J, the adapter card structure 201 can fix a plurality of (one, two, three or even more) connector structures 10, and correspondingly can be plugged with a plurality of (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 implementations of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application.
