Abstract
Description
Technical Field
[0001] This application relates to the field of computing device technology, and more particularly to a cable assembly and a computing device. Background Technology
[0002] High-speed serial computer expansion bus (Peripheral Component Interconnect Express, PCIe) devices are based on the PCIe standard and are widely used in computing devices. Taking a server as an example, when the server host connects PCIe devices through PCIe slots, some PCIe devices (such as data processing unit cards, DPUs) often need to be independently powered on or off. This way, when the server host is powered off, the PCIe device can still function normally. For example, the PCIe device can continue to be controlled by the cloud management platform, unaffected by the host's power-on or power-off.
[0003] However, the host computer in related technologies cannot support independent power-on or power-off control of PCIe devices. This can only be achieved by modifying the motherboard circuitry, resulting in high time and development costs. Therefore, how to enable the host computer to support independent power-on or power-off control of PCIe devices at a lower cost has become a pressing technical problem to be solved. Utility Model Content
[0004] This application provides a cable assembly and a computing device for enabling independent power-on or power-off control of PCIe devices at a lower cost.
[0005] On one hand, embodiments of this application provide a computing device, the computing device including a motherboard, an adapter board, a PCIe device, a first connector, a second connector, a third connector, signal lines, and a first power line. The adapter board is connected to the motherboard. The first connector includes a first data pin and is connected to the motherboard. The second connector includes a first power pin and a second data pin, and the PCIe device is connected to the adapter board via the second connector. One end of the signal line is connected to the first data pin, and the other end is connected to the second data pin. The third connector includes a second power pin and is connected to a second power supply. One end of the first power line is connected to the second power pin, and the other end is connected to the first power pin.
[0006] In the computing device of this application embodiment, the motherboard can be connected to a first power supply, and a second power supply provides normal operating power to the PCIe device through a third connector, a first power line, and a second connector. That is, the motherboard's normal operating power is provided by the first power supply, while the PCIe device's normal operating power is provided by the second power supply. In this case, the PCIe device is powered solely by the second power supply. When the computing device is powered down (e.g., all devices in the computing device except the management controller and / or complex programmable logic device in the motherboard are powered down), the management controller or complex programmable logic device can still control the second power supply to continuously provide normal operating power to the PCIe device, ensuring that the PCIe device operates normally regardless of the computing device's power-down. This allows for independent power-on or power-off control of the PCIe device without changing the motherboard's circuit design, i.e., with lower time and development costs.
[0007] In some embodiments, the first connector further includes a third power pin, which is floating. In this case, the first connector is fully connected to the motherboard interface, which can avoid the problem of misconnection between the first connector and the motherboard interface, leading to incorrect connection of the first pin to the motherboard's data or power terminals, and can improve the stability of the interface connection between the first connector and the motherboard.
[0008] In some embodiments, the third connector further includes a fourth power pin, and the computing device further includes a fourth connector and a second power line. The fourth connector includes a fifth power pin and is used to connect to a PCIe device. One end of the second power line is connected to the fourth power pin, and the other end is connected to the fifth power pin. In this case, the second power supply can also provide additional power to the PCIe device through the third connector, the second power line, and the fourth connector. Furthermore, when the computing device is powered down (e.g., all devices in the computing device except for the management controller and / or complex programmable logic devices in the motherboard are powered down), the management controller or complex programmable logic devices can also control the second power supply to continuously provide additional power to the PCIe device, thereby improving the stability and efficiency of the PCIe device's power supply.
[0009] In some embodiments, the number of the fourth power pins is greater than the number of the second power pins, so that the second power supply can provide a larger amount of additional power to the PCIe device through the third connector, the second power line and the fourth connector, which can accommodate PCIe devices with higher power.
[0010] In some embodiments, the computing device further includes a first protective sleeve, which comprises a first sub-sleeve, a second sub-sleeve, and a third sub-sleeve. The first sub-sleeve encloses multiple signal lines, the second sub-sleeve encloses multiple first power lines, and the third sub-sleeve is connected to the ends of the first and second sub-sleeves near the third connector, and encloses multiple signal lines and multiple first power lines. In this case, the first protective sleeve can consolidate and protect the signal lines and first power lines, preventing them from becoming tangled, reducing safety hazards, and lowering the risk of leakage or open circuits caused by scratches on the signal lines and first power lines.
[0011] In some embodiments, the signal line includes a first conductor and a first insulating layer, the first insulating layer wrapping around the first conductor. The first power line includes a second conductor and a second insulating layer, the second insulating layer wrapping around the second conductor; the thickness of the second insulating layer is greater than the thickness of the first insulating layer. The first sub-sleeve is connected to the first connector, and the third sub-sleeve is connected to the second connector, so that the signal line is completely wrapped by the first and third sub-sleeves, preventing the signal line from being exposed to external scratches, which could lead to signal line leakage or open circuit.
[0012] In some embodiments, the second sub-sleeve is spaced apart from the third connector, which can reduce the consumption of materials for the second sub-sleeve and lower the cost.
[0013] On the other hand, embodiments of this application provide a cable assembly including a first connector, a second connector, a signal line, a third connector, and a first power line. The first connector includes a first data pin. The second connector includes a first power pin and a second data pin. One end of the signal line is connected to the first data pin, and the other end is connected to the second data pin. The third connector includes a second power pin. One end of the first power line is connected to the second power pin, and the other end is connected to the first power pin.
[0014] In some embodiments, the first connector further includes a third power pin, which is floating.
[0015] In some embodiments, the third connector further includes a fourth power pin, and the cable assembly further includes a fourth connector and a second power line, the fourth connector including a fifth power pin. One end of the second power line is connected to the fourth power pin, and the other end is connected to the fifth power pin.
[0016] In some embodiments, the number of the fourth power supply pins is greater than the number of the second power supply pins.
[0017] In some embodiments, the cable assembly further includes a first protective sleeve, which includes a first sub-sleeve, a second sub-sleeve, and a third sub-sleeve. The first sub-sleeve wraps around multiple signal lines, the second sub-sleeve wraps around multiple first power lines, and the third sub-sleeve is connected to the end of the first sub-sleeve and the second sub-sleeve near the third connector, and the third sub-sleeve wraps around multiple signal lines and multiple first power lines.
[0018] In some embodiments, the signal line includes a first conductor and a first insulating layer, the first insulating layer wrapping around the first conductor. The first power line includes a second conductor and a second insulating layer, the second insulating layer wrapping around the second conductor; the thickness of the second insulating layer is greater than the thickness of the first insulating layer. The first sub-sleeve is connected to the first connector, and the third sub-sleeve is connected to the second connector.
[0019] In some embodiments, the second sub-sleeve is spaced apart from the third connector.

[0038] The technical solutions in some embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments provided in this application are within the scope of protection of this application.
[0039] In describing some embodiments, the term "connection" and its derivative expressions may be used. For example, the term "connection" as used in describing some embodiments should be interpreted broadly, such as referring to a mechanical connection or an electrical connection; a fixed connection or a detachable connection or an integral connection; a direct connection or an indirect connection through an intermediate medium; or a connection within two components. Those skilled in the art will understand the specific meaning of the above terms herein according to the specific circumstances.
[0040] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this application, unless otherwise stated, "a plurality of" means two or more.
[0041] In this article, the term "and / or" is merely a description of the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone.
[0042] As used herein, “vertical” includes the described situation and situations that are similar to the described situation, within an acceptable deviation range, which is determined by those skilled in the art taking into account the measurement under discussion and the error associated with the measurement of a particular quantity (i.e., the limitations of the measurement system). For example, “vertical” includes absolute verticality and approximate verticality, where an acceptable deviation range for approximate verticality could be, for example, within 10°.
[0043] It should be noted that in the embodiments of this application, the words "exemplarily" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplarily" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplarily" or "for example" is intended to present the relevant concepts in a specific manner.
[0044] In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0045] like Figure 1As shown, the computing device 1000 can be a computing device with communication functions, computing functions, or other functions. For example, the computing device 1000 can be a server, router, switch, desktop computer, portable computer, wireless terminal, communication equipment, or digital multimedia player with data processing and data storage functions.
[0046] The following uses computing device 1000 as an example to illustrate some embodiments of this application. However, the implementation of this application is not limited to this, and any other computing device can be considered as long as the same technical concept is applied.
[0047] The servers can be rack servers, full rack servers, blade servers, or tower servers, etc. Figure 1 The example shown is a rack server. However, this server can be a general-purpose server, a graphics processing server, a data processing server, an artificial intelligence server, etc., and the embodiments in this application are not limited to these.
[0048] like Figure 2 As shown, the computing device 1000 includes a housing 100 and a circuit board module 200. The housing 100 has a receiving cavity inside, and the circuit board module 200 is disposed in the receiving cavity of the housing 100, and the circuit board module 200 is protected from external damage.
[0049] In some embodiments, see Figure 2 The circuit board module 200 includes a motherboard 300 and a first power supply 400. The motherboard 300 and the first power supply 400 are connected by a power cable. The first power supply 400 is used to supply power to the motherboard 300.
[0050] Among them, combined Figure 3 The motherboard 300 may include a central processing unit (CPU) 310, a baseboard management controller (BMC) 320, and a complex programmable logic device (CPLD) 330. The CPU 310 communicates with the BMC and CPLD via a transmission channel, which may include one or more of the following: universal serial bus (USB), PCIe, enhanced serial peripheral interface (eSPI), or low pin count interface (LPC).
[0051] In this embodiment, the management controller 320 is used to manage and detect the status of hardware devices in the motherboard 300. For example, the management controller 320 can be used to detect the status of the central processing unit 310 in the motherboard 300. The operation of the management controller 320 does not depend on other devices in the motherboard 300.
[0052] In this embodiment, the complex programmable logic device 330 can be used to implement customized hardware functions, such as the generation and processing of control signals, to receive and control various signals, such as power-on and power-off, and to communicate with the management controller 320 to transmit hardware status information. The operation of the complex programmable logic device 330 does not depend on other devices in the motherboard 300.
[0053] In addition, the motherboard 300 may also include virtual machines (VMs) and a virtual machine management system (Hypervisor). To save energy, when business is idle, the computing device 1000 can migrate the VMs in the motherboard 300 to other computing devices, and then power down the computing device 1000 (for example, powering down some or all of the devices in the computing device 1000 except for the management controller 320 and / or complex programmable logic device 330 in the motherboard 300) to reduce energy consumption.
[0054] Please continue reading. Figure 2 and Figure 3 The circuit board module 200 may also include a memory module 500, which is connected to the motherboard 300. For example, the memory module 500 is plugged into the motherboard 300, so that the memory module 500 is connected to the central processing unit 310 of the motherboard 300. The central processing unit 310 can address via the bus and perform read and write operations on the memory module 500.
[0055] Please continue reading. Figure 2 and Figure 3 The circuit board module 200 may also include an adapter board 600 and a PCIe device 700. The adapter board 600 is connected to the motherboard 300, for example, the adapter board 600 is plugged into the motherboard 300, and the PCIe device 700 is connected to the motherboard 300 through the adapter board 600. In this case, the adapter board 600 can realize flexible configuration and resource allocation of the PCIe device, and can directly allocate the PCIe device to a specific virtual machine. This allows the virtual machine to bypass the host operating system and directly access and control the PCIe device, improving the performance and utilization efficiency of the computing device 1000.
[0056] The aforementioned PCIe device 700 includes any type of expansion card based on the PCIe standard, such as a graphics card, network card, sound card, video capture card, and fixed hard drive expansion card. For example, the PCIe device 700 includes a DPU, but the embodiments of this application are not limited thereto.
[0057] In addition, combined Figure 3 The circuit board module 200 may further include a second power supply 900, which is connected to the PCIe device 700 to provide additional power to the PCIe device 700, thereby improving the stability and efficiency of power supply to the PCIe device 700. The second power supply 900 may, for example, be located on the adapter board 600. In this embodiment, the second power supply 900 may be an auxiliary power supply in a server.
[0058] In some embodiments, see Figure 2 The circuit board module 200 may also include a fan 800, which is connected to a first power supply 400 via a power cable. The first power supply 400 also supplies power to the fan 800. In this configuration, the memory module 500 and the central processing unit 310 may be arranged, for example, along a first direction X; along a second direction Y, the adapter board 600 and the fan 800 are positioned on opposite sides of the central processing unit 310. Along the second direction Y, the first power supply 400 and the adapter board 600 may be positioned on the same side of the central processing unit 310. The first direction X intersects the second direction Y; for example, the first direction X is perpendicular to the second direction Y.
[0059] Currently, some PCIe devices often require independent power-on or power-off control. For example, a Data Processing Unit (DPU) is a dedicated processor that provides virtualization services for data center infrastructure such as networking, storage, security, and management around data processing. When the server is in standby mode, the DPU still needs to function normally; for instance, it should remain under the control of the cloud management platform and unaffected by the server's power on / off cycles. However, in related technologies, the DPU is powered by the motherboard. When the server is in standby mode, the motherboard powers down, causing the DPU to power down as well. The motherboard cannot support independent power-on or power-off control for the DPU; it can only be achieved by modifying the motherboard's circuitry, resulting in high time and development costs.
[0060] Based on this, see Figure 3 and Figure 4 Some embodiments of this application also provide a cable assembly 10, including a first connector 11, a second connector 12, a signal line 13, a third connector 14, and a first power line 15.
[0061] See Figure 3 and Figure 4 The first connector 11 is used to connect to the motherboard 300, that is, the first connector 11 is connected to the motherboard 300. See also... Figure 4 and Figure 5The first connector 11 includes a first base 111 and a first pin 112. The first pin 112 is disposed on the first base 111 and fixedly connected to the first base 111, so that the first base 111 can support and fix the first pin 112, preventing the first pin 112 from shifting or deforming during operation. Furthermore, combined with... Figure 3 , Figure 4 and Figure 6 The first base 111 may be provided with a first latch 113 and a plug-in structure 114. The first latch 113 is latched with the interface of the motherboard 300, and the plug-in structure 114 is plugged into the interface of the motherboard 300 to improve the connection stability between the first connector 11 and the motherboard 300.
[0062] See Figure 3 and Figure 4 The second connector 12 is used to insert the PCIe device 700. Specifically, the PCIe device 700 is connected to the adapter board 600 via the second connector 12. The adapter board 600 may have a slot, and the second connector 12 can be fixed within the slot of the adapter board 600. For example, the second connector 12 can be fixed to the adapter board 600 by screwing, soldering, or other fixing methods, and the PCIe device 700 is connected to the second connector 12. Wherein, for example... Figure 4 As shown, the second connector 12 includes a second base 121 and a second pin 122. The second pin 122 is disposed on the second base 121 and fixedly connected to the second base 121, so that the second base 121 can support and fix the second pin 122, preventing the second pin 122 from shifting or deforming during operation. Furthermore, combined with... Figure 3 , Figure 4 and Figure 7 The second base 121 includes a base 1211 and a plug-in part 1212. The base 1211 is connected to the adapter plate 600. The plug-in part 1212 is located on the side of the base 1211 away from the adapter plate 600. The surface of the plug-in part 1212 away from the base 1211 is provided with a plug-in groove, into which the PCIe device 700 can be plugged in.
[0063] Based on this, such as Figure 4 and Figure 5 As shown, the first pin 112 may include, for example, a first data pin 1121, and the second pin 122 may include a second data pin 1221. Combined with... Figure 3 , Figure 4 , Figure 5 and Figure 8 One end of signal line 13 is connected to the first data pin 1121, and the other end is connected to the second data pin 1221. In this way, PCIe device 700 can receive control signals from motherboard 300 to realize various functions, such as improving image processing capabilities, meeting network access requirements, and improving audio output quality.
[0064] See Figure 3 and Figure 4 The third connector 14 is used to connect to the second power supply 900, that is, the third connector 14 is connected to the second power supply 900. Wherein, as... Figure 9 As shown, the third connector 14 includes a third base 141 and a third pin 142. The third pin 142 is disposed on the third base 141 and fixedly connected to the third base 141, so that the third base 141 can support and fix the third pin 142, preventing the third pin 142 from shifting or deforming during operation. Furthermore, combined with... Figure 3 , Figure 4 and Figure 9 The third base 141 may be provided with a second latch 143, which can be engaged with the interface of the second power supply 900 to improve the connection stability between the third connector 14 and the second power supply 900.
[0065] Based on this, such as Figure 4 and Figure 9 As shown, the third pin 142 includes a second power supply pin 1421, and the second pin 122 also includes a first power supply pin 1222. Combined with... Figure 3 , Figure 4 , Figure 9 and Figure 10 One end of the first power line 15 is connected to the second power pin 1421, and the other end is connected to the first power pin 1222, so that the second power supply 900 provides normal operating power to the PCIe device 700 through the third connector 14, the first power line 15 and the second connector 12.
[0066] As described above, the motherboard 300 can be connected to the first power supply 400, and the second power supply 900 provides power to the PCIe device 700 for normal operation through the third connector 14, the first power cable 15, and the second connector 12. In other words, the motherboard 300 is powered by the first power supply 400, and the PCIe device 700 is powered by the second power supply 900. At this time, the PCIe device 700 is powered by the second power supply 900 alone. When the computing device 1000 is powered down (for example, when all devices in the computing device 1000 except for the management controller 320 and / or the complex programmable logic device 330 in the motherboard 300 are powered down), the management controller 320 or the complex programmable logic device 330 can still control the second power supply 900 to continuously provide power to the PCIe device 700 for normal operation, so that the PCIe device 700 can work normally and is not affected by the power-down of the computing device 1000. In this way, the PCIe device 700 can be independently controlled to power on or off without changing the circuit design of the motherboard 300, that is, with lower time and development costs.
[0067] In some embodiments, such as Figure 3 and Figure 4 As shown, the cable assembly 10 also includes a fourth connector 16 and a second power cord 17, and the third connector 14 is also connected to the fourth connector 16 via the second power cord 17.
[0068] like Figure 3 , Figure 4 and Figure 11 As shown, the fourth connector 16 is used to connect the PCIe device 700, that is, the PCIe device 700 is connected to the fourth connector 16. The fourth connector 16 includes a fourth base 161 and a fourth pin 162. The fourth pin 162 is disposed on the fourth base 161 and fixedly connected to the fourth base 161, so that the fourth base 161 can support and fix the fourth pin 162, preventing displacement and deformation of the fourth pin 162 during operation. Furthermore, the fourth base 161 may be provided with a third latch 163, which can engage with the interface of the PCIe device 700 to improve the connection stability between the fourth connector 16 and the PCIe device 700.
[0069] Based on this, such as Figure 9 and Figure 11 As shown, the third pin 142 also includes a fourth power supply pin 1422, and the fourth pin 162 includes a fifth power supply pin 1621. Combined with... Figure 3 , Figure 4 , Figure 9 , Figure 11 and Figure 12 One end of the second power line 17 is connected to the fourth power pin 1422, and the other end is connected to the fifth power pin 1621, so that the second power supply 900 provides additional power to the PCIe device 700 through the third connector 14, the second power line 17, and the fourth connector 16. Here, the number of fourth power pins 1422 can, for example, be greater than the number of second power pins 1421, so that the second power supply 900 can provide a larger amount of additional power to the PCIe device 700 through the third connector 14, the second power line 17, and the fourth connector 16, which can accommodate PCIe devices 700 with higher power. Of course, the number of fourth power pins 1422 can also be less than or equal to the number of second power pins 1421; this embodiment does not specifically limit this.
[0070] In this configuration, the second power supply 900 can also provide additional power to the PCIe device 700 via the third connector 14, the second power line 17, and the fourth connector 16. At this time, when the computing device 1000 is powered down (e.g., all devices in the computing device 1000 except for the management controller 320 and / or the complex programmable logic device 330 in the motherboard 300 are powered down), the management controller 320 or the complex programmable logic device 330 can also control the second power supply 900 to continuously provide additional power to the PCIe device 700, thereby improving the stability and efficiency of the power supply to the PCIe device 700.
[0071] It should be understood that the interface connecting the motherboard 300 to the first connector 11 includes not only data terminals for transmitting control signals, but also power terminals for transmitting power signals.
[0072] Based on this, the first pin 112 may only include the first data pin 1121, which is connected to the data terminal to transmit control signals. This helps to reduce the size of the first connector 11, reduce the space occupied by the first connector 11, reduce the material consumption of the first connector 11, and thus reduce the manufacturing cost of the cable assembly 10.
[0073] Alternatively, in addition to the first data pin 1121, the first pin 112 may also include a third power supply pin 1122, which is floating. Here, "floating" means that the third power supply pin 1122 neither receives a high level nor a low level. That is, the third power supply pin 1122 is only connected to the power terminal, but not to the signal line 13, forming an open circuit at the third power supply pin 1122. In this case, the interface between the first connector 11 and the motherboard 300 is fully mated, avoiding misalignment between the first connector 11 and the motherboard 300's interface, which could lead to incorrect connection of the first pin 112 to the data or power terminal of the motherboard 300. This also improves the stability of the interface connection between the first connector 11 and the motherboard 300.
[0074] In some embodiments, see Figure 4 and Figure 13 The cable assembly 10 also includes a first protective sleeve 18, which includes a first sub-sleeve 181, a second sub-sleeve 182, and a third sub-sleeve 183. For example... Figure 8 and Figure 13 As shown, the first sub-suite 181 encloses multiple signal lines 13, grouping them together. (As...) Figure 10 and Figure 13 As shown, the second sub-suite 182 encloses multiple first power cables 15, grouping them together. Figure 4 , Figure 13 and Figure 14 As shown, the third sub-sleeve 183 is connected to the first sub-sleeve 181 and the second sub-sleeve 182 near the third connector 14, and the third sub-sleeve 183 wraps around multiple signal lines 13 and multiple first power lines 15, grouping them together. In this case, the first protective sleeve 18 can group and protect the signal lines 13 and the first power lines 15, preventing the lines (signal lines 13 and first power lines 15) from getting tangled together, reducing safety hazards, and lowering the risk of leakage or open circuit caused by scratches on the signal lines 13 and the first power lines 15.
[0075] Understandably, see Figure 8 The signal line 13 includes a first conductor 131 and a first insulating layer 132. The first insulating layer 132 wraps around the first conductor 131 to insulate the multiple signal lines 13 from each other. (See also...) Figure 10 The first power line 15 includes a second conductor 151 and a second insulating layer 152. The second insulating layer 152 wraps around the second conductor 151 to insulate the multiple first power lines 15. The thickness of the second insulating layer 152 is greater than the thickness of the first insulating layer 132. That is, if the first insulating layer 132 is thinner, the first conductor 131 is at greater risk of being scratched by external forces; if the second insulating layer 152 is thicker, the second conductor 151 is at less risk of being scratched by external forces.
[0076] At this time, as Figure 4 , Figure 8 and Figure 13 As shown, the first sub-sleeve 181 is connected to the first connector 11, and the third sub-sleeve 183 is connected to the second connector 12. In this way, the signal line 13 is completely wrapped by the first sub-sleeve 181 and the third sub-sleeve 183, which prevents the signal line 13 from being exposed to the outside world and scratched, which could lead to leakage or open circuit of the signal line 13.
[0077] Furthermore, the second sub-sleeve 182 is connected to the third connector 14 so that the first power line 15 is completely enclosed by the second sub-sleeve 182, preventing the signal line 13 from being exposed and scratched by the outside world, which could cause leakage or open circuit in the first power line 15. Or, as Figure 4 and Figure 13 As shown, the second sub-sleeve 182 and the third connector 14 are spaced apart, which can reduce the consumables of the second sub-sleeve 182 and reduce costs. For example, the distance between the second sub-sleeve 182 and the third connector 14 can be 5mm to 15mm, such as 9mm to 11mm, for example, the distance between the second sub-sleeve 182 and the third connector 14 can be any one of 9mm, 10mm and 11mm.
[0078] The aforementioned first protective sleeve 18, located near the ends of the first connector 11, the second connector 12, and the third connector 14, can connect to internal wiring. For example, as... Figure 4 and Figure 13 As shown, the first sub-sleeve 181 includes a first sub-segment 1811, a second sub-segment 1812, and a third sub-segment 1813 connected in sequence. The first sub-segment 1811 is located on the side of the second sub-segment 1812 closer to the first connector 11. The first sub-segment 1811 and the third sub-segment 1813 are connected to the signal line 13 (see...). Figure 8 The second sub-sleeve 182 includes a fourth sub-segment 1821, a fifth sub-segment 1822, and a sixth sub-segment 1823 connected in sequence. The fourth sub-segment 1821 is located on the side of the fifth sub-segment 1822 closer to the third connector 14. The fourth sub-segment 1821 and the sixth sub-segment 1823 are connected to the first power line 15 (see...). Figure 10 The third sub-sleeve 183 is connected to signal line 13 or first power line 15 (see...). Figure 14 )connect.
[0079] The length of the first segment 1811 is 25mm to 35mm. For example, the length of the first segment 1811 is 27mm to 33mm, such as any one of 27mm, 28mm, 29mm, 30mm, 31mm, 32mm and 33mm.
[0080] The length of the fourth sub-segment 1821 is 15mm to 25mm. For example, the length of the fourth sub-segment 1821 is 18mm to 22mm, such as any one of 18mm, 19mm, 20mm, 21mm and 11mm.
[0081] The sum of the lengths of the third sub-segment 1813 and the third sub-sleeve 183 is 25mm to 35mm. For example, the sum of the lengths of the third sub-segment 1813 and the third sub-sleeve 183 is 27mm to 33mm. For example, the sum of the lengths of the third sub-segment 1813 and the third sub-sleeve 183 is any one of 27mm, 28mm, 29mm, 30mm, 31mm, 32mm and 33mm.
[0082] The sum of the lengths of the sixth sub-segment 1823 and the third sub-sleeve 183 is 25mm to 35mm. For example, the sum of the lengths of the sixth sub-segment 1823 and the third sub-sleeve 183 is 27mm to 33mm. For example, the sum of the lengths of the sixth sub-segment 1823 and the third sub-sleeve 183 is any one of 27mm, 28mm, 29mm, 30mm, 31mm, 32mm and 33mm.
[0083] In some embodiments, see Figure 4 , Figure 12 and Figure 15The cable assembly 10 also includes a second protective sleeve 19 that wraps around multiple second power lines 17. Each second power line 17 includes a third conductor 171 and a third insulation layer 172. The third insulation layer 172 wraps around the third conductor 171 to insulate the multiple second power lines 17 from each other. The thickness of the third insulation layer 172 is greater than the thickness of the first insulation layer 132. That is, the third insulation layer 172 is thicker, and the third conductor 171 is less likely to be scratched by external forces.
[0084] At this time, the second protective sleeve 19 is connected to the third connector 14 and the fourth connector 16, so that the second power cord 17 is completely wrapped by the second protective sleeve 19, preventing the second power cord 17 from being exposed and scratched by the outside world, which could lead to leakage or open circuit. Alternatively, the second protective sleeve 19 can be spaced apart from the third connector 14 and the fourth connector 16, which can reduce the consumables of the second protective sleeve 19 and lower the cost. For example, the distance between the second protective sleeve 19 and the third connector 14 can be 5mm to 15mm, for example, the distance between the second protective sleeve 19 and the third connector 14 can be 9mm to 11mm, such as any one of 9mm, 10mm and 11mm. For example, the distance between the second protective sleeve 19 and the fourth connector 16 can be 5mm to 15mm, for example, the distance between the second protective sleeve 19 and the fourth connector 16 can be 9mm to 11mm, such as any one of 9mm, 10mm and 11mm.
[0085] The second protective sleeve 19, located near the ends of the third connector 14 and the fourth connector 16, can be connected to the second power cable 17. Exemplarily, the second protective sleeve 19 includes a seventh segment 191, an eighth segment 192, and a ninth segment 193 connected in sequence. The seventh segment 191 is located on the side of the eighth segment 192 near the third connector 14, and the seventh segment 191 and the ninth segment 193 are connected to the second power cable 17.
[0086] The length of the seventh sub-segment 191 is 15mm to 25mm. For example, the length of the seventh sub-segment 191 is 18mm to 22mm, such as any one of 18mm, 19mm, 20mm, 21mm and 11mm.
[0087] The length of the aforementioned ninth sub-segment 193 is 15mm to 25mm. For example, the length of the ninth sub-segment 193 is 18mm to 22mm, such as any one of 18mm, 19mm, 20mm, 21mm and 11mm.
[0088] In some embodiments, see Figure 4The first base 111 has a first surface and a second surface that are arranged opposite to each other. The signal line 13 is connected to the first data pin 1121 on the second surface of the first base 111. The first pin 112 extends out of the first surface to form a gold finger structure.
[0089] At this time, when the cable assembly 10 is not installed in the computing device 1000, that is, when the cable assembly 10 is stored or transported separately, the cable assembly 10 may also include a dust cover. The dust cover is connected to the first base 111 and forms a first protective cavity with the first base 111. The gold fingers are located in the first protective cavity. In this way, the dust cover can protect the gold fingers from external damage and prevent dust from falling on the gold fingers during storage or transportation, which could cause poor electrical connection between the first connector 11 and the motherboard 300.
[0090] In addition, see Figure 16 When the cable assembly 10 is not installed in the computing device 1000, i.e., when the cable assembly 10 is stored or transported separately, the cable assembly 10 may also include a protective box 210, including a box body 211 and a cover plate 212, which fasten together to form a second protective cavity with an opening. The second connector 12 is located in the second protective cavity, and the signal line 13 and the first power line 15 are connected to the second connector 12 through the opening. In this case, the protective box 210 can protect the second connector 12 from external damage and prevent dust from falling on the second pin 122 during storage or transportation, which could cause a poor electrical connection between the second connector 12 and the PCIe device 700.
