After the power supply lines set on the circuit board are reduced, the layout density of other conductive structures set on the circuit board can be increased, and then the length or width direction of the circuit board can be reduced, or the number of layers of the conductive layer of the circuit board can be reduced, so that the size of the circuit board can be made smaller. In addition, after the load is supplied with power through the power supply cable outside the circuit board, the current flowing through the circuit board becomes less, and the circuit board is not prone to overheating. In addition, the flow cross-section of the power supply cable is not limited by the circuit board, so that the flow cross-section of the power supply cable can be larger, so that the current loss of the power connector when supplying power to the load through the power supply cable is smaller.

[0046] The terms used in the implementation manners part of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application. The implementation manners of the embodiments of the present application will be described in detail below with reference to the drawings.

[0047] An embodiment of the present application provides a computing device, which may include, but is not limited to, a server, etc. For example, the computing device may be a rack-mounted server.

[0048] Figure 1 Schematic diagram of a computing device provided by an embodiment of the present application.

[0049] Such as Figure 1As shown, in the embodiment of the present application, the computing device includes a power supply module 20 (power supply unit, PSU) and a motherboard 10. The motherboard 10 includes a circuit board 100, a power connector 200, and a load 300. Both the load 300 and the power connector 200 are disposed on the surface of the circuit board 100, and the circuit board 100 can be used to carry the load 300 and the power connector 200. The load 300 is electrically connected to the power connector 200, and the power connector 200 is used to be electrically connected to the power supply module 20, so that the power supply module 20 can be electrically connected to the load 300 through the power connector 200. The power supply module 20 can be used to be electrically connected to a power supply device such as a distribution box or the mains power, so that the power supply device such as a distribution box or the mains power can supply power to the load 300 through the power supply module 20. Exemplarily, the power supply module 20 may have a gold finger plug-in portion 21, and the gold finger plug-in portion 21 can be plugged on the power connector 200 to fix and electrically connect the power supply module 20 to the power connector 200.

[0050] The power supply module 20 can adjust the current from a power supply device such as a distribution box or the mains power to the current required by the load 300 and then stably output it to the load 300. For example, when the current required by the load 300 is alternating current, the power supply module 20 can convert the direct current from a power supply device such as a distribution box into the alternating current required by the load 300 and then output it to the load 300. Another example is that when the current required by the load 300 is direct current, the power supply module 20 can convert the alternating current from a power supply device such as a distribution box or the mains power into the direct current required by the load 300 and then output it to the load 300. Still another example is that when the voltage of the current from a power supply device such as a distribution box or the mains power is higher or lower than the voltage of the current required by the load 300, the power supply module 20 can adjust the voltage of the current from a power supply device such as a distribution box or the mains power to the voltage required by the load 300 and then output it to the load 300.

[0051] In the embodiment of the present application, the computing device may further include a housing 30. Both the circuit board 100 and the load 300 can be disposed inside the housing 30, and the circuit board 100 can be fixedly connected to the inner wall of the housing 30.

[0052] In some examples, the power supply module 20 and the power connector 200 are disposed inside the housing 30, and the power supply module 20 is connected to the power connector 200 inside the housing 30.

[0053] In some other examples, the power supply module 20 can be disposed outside the housing 30. The housing 30 has a through-wall hole that communicates the inner cavity of the housing 30 with the outside. The power supply connector 200 is inserted through the through-wall hole, such that a part of the power supply connector 200 is located inside the housing 30 and a part is located outside the housing 30. The circuit board 100 is connected to the part of the power supply connector 200 that is located inside the housing 30. The power supply module 20 is used to be connected to the part of the power supply connector 200 that is located outside the housing 30 (not shown).

[0054] Exemplarily, one or more loads 300 can be disposed on the surface of the circuit board 100.

[0055] Exemplarily, any one of the loads 300 disposed on the surface of the circuit board 100 can include, but is not limited to, a processor, a memory, a board card, a fan, a hard disk, etc. Among them, the processor can include, but is not limited to, a central processing unit (CPU), a graphics processing unit (GPU), a data processing unit (DPU), etc.

[0056] Exemplarily, two power supply connectors 200 can be disposed on the surface of the circuit board 100. Each power supply connector 200 can be respectively used to be electrically connected to a power supply module 20. Each power supply connector 200 can be electrically connected to all the loads 300, such that when one of the power supply connectors 200 or the power supply module 20 electrically connected to this power supply connector 200 fails, the loads 300 can be powered by the other power supply connector 200 and the power supply module 20 electrically connected to this power supply connector 200.

[0057] Exemplarily, the circuit board 100 can include multiple conductive layers (not shown) and insulating layers (not shown) located between adjacent two conductive layers. The adjacent two conductive layers are connected through the insulating layer therebetween. The multiple conductive layers can include surface conductive layers respectively located on the two side surfaces in the thickness direction of the circuit board 100 and inner conductive layers located between the two surface conductive layers on both sides of the circuit board 100.

[0058] In related technologies, a power connector and a load disposed on the surface of a circuit board are often electrically connected through a power trace located in an inner conductive layer. Subject to the requirements of safety isolation, there needs to be a certain distance between the power trace and other conductive structures. In this way, a relatively large number of power traces disposed in the circuit board will make the size of the circuit board larger. As the performance of computing devices continues to improve and the power consumption of loads continues to increase, the current flowing through the power traces needs to become larger. To meet the large-current power-on requirements of loads with large power consumption, the width and thickness of the power traces are often increased to improve the current-carrying capacity of the power traces. However, after the width and thickness of the power traces are increased, the size of the circuit board will further increase in at least one of the length direction and the width direction, or the number of conductive layers of the circuit board will further increase, which will further increase the size of the circuit board. In addition, when current flows through the power traces of the conductive layer, the power traces will heat up, making the circuit board prone to overheating problems. In addition, when the power connector supplies power to the load through the power trace, the current-carrying cross-section of the power trace is small, and the loss of current transmission in the power trace is large.

[0059] Figure 2 Schematic diagram of another computing device provided by an embodiment of the present application.

[0060] Based on this, as Figure 2 shown, the computing device further includes a power supply cable 400. The power supply cable 400 is located outside the circuit board 100. At least one load 300 is electrically connected to the power connector 200 through the power supply cable 400. The power connector 200 is configured to supply power to the load 300 electrically connected to the power supply cable 400 through the power supply cable 400. In this way, the power connector 200 can supply power to at least some of the loads 300 disposed on the circuit board 100 through the power supply cable 400 located outside the circuit board 100, which can reduce the setting of the power traces 110 on the circuit board 100, or even no longer require the power traces 110 to be disposed on the circuit board 100. After the power traces 110 disposed on the circuit board 100 are reduced, the layout density of other conductive structures disposed on the circuit board 100 can be improved, and thus the size of the circuit board 100 in the length direction or the width direction can be reduced, or the number of conductive layers of the circuit board 100 can be reduced. In this way, the size of the circuit board 100 can be made smaller. In addition, after at least some of the loads are supplied with power through the power supply cable 400 outside the circuit board 100, the current flowing through the circuit board 100 becomes smaller, and the circuit board 100 is not prone to overheating. In addition, the current-carrying cross-section of the power supply cable 400 is not limited by the circuit board 100, so that the current-carrying cross-section of the power supply cable 400 can be made larger, and the current loss when the power connector 200 supplies power to the load 300 through the power supply cable 400 is smaller.

[0061] Figure 3 Schematic diagram of yet another computing device provided by an embodiment of the present application.

[0062] As Figure 3 shown, in the embodiment of the present application, the power supply cable 400 is fixedly connected to the power connector 200. Specifically, the power connector 200 includes a base 210 and power terminals. The base 210 is made of an insulating material. The base 210 is fixedly connected to the circuit board 100. The power terminals are fixedly connected to the base 210. The power module 20 is electrically connected to the power terminals. The power terminals include a first power terminal 220 for connecting to the power supply cable 400. The power supply cable 400 is fixedly and electrically connected to the first power terminal 220, so that the first power terminal 220 is electrically connected to the load 300 electrically connected to the power supply cable 400 through the power supply cable 400. The first power terminal 220 is used to supply power to the load 300 electrically connected to the power supply cable 400 through the power supply cable 400, so that the power module 20 can supply power to the load 300 electrically connected to the power supply cable 400 through the first power terminal 220 and the power supply cable 300. In this way, compared with the solution in which the power supply cable 400 is electrically connected to the power connector 200 through an adapter board and other connectors, there is no current loss caused by the transfer between the power supply cable 400 and the first power terminal 220, and the loss of current transmission between the power supply cable 400 and the first power terminal 220 is small. In addition, since there is no need to set other connectors and adapter boards, the production and maintenance costs of the computing device can be reduced.

[0063] In some examples, the power supply cable 400 is adhesively fixed to the first power terminal 220 through a conductive adhesive, so that the power supply cable 400 is electrically connected to the adhesively fixed first power terminal 220. In this way, it is more convenient to connect the power supply cable 400 to the first power terminal 220.

[0064] In some examples, the power supply cable 400 is fixedly connected to the first power terminal 220 by welding, so that the power supply cable 400 is electrically connected to the welded first power terminal 220. In this way, the impedance at the connection between the power supply cable 400 and the first power terminal 220 is small, which can reduce the reduction of the voltage amplitude between the power supply cable 400 and the first power terminal 220, and reduce the loss of current transmission between the power supply cable 400 and the first power terminal 220. In addition, the stability of the fixed connection between the power supply cable 400 and the first power terminal 220 is less affected by environmental factors such as temperature, and the connection between the power supply cable 400 and the first power terminal 220 is relatively stable.

[0065] Exemplarily, one end of the power supply cable 400 can be welded to the first power terminal 220 by ultrasonic welding, laser welding or other methods.

[0066] Figure 4 It is a schematic diagram of the connection between the power connector of a computing device and the power supply cable provided by the embodiment of the present application.

[0067] As Figure 4 shown, a portion of the power supply cable 400 is stacked on the upper surface of the first power supply terminal 220. The portion of the power supply cable 400 stacked on the upper surface of the first power supply terminal 220 is fixed to and electrically connected to the first power supply terminal 220. That is to say, the portion of the power supply cable 400 used for connecting to the first power supply terminal 220 is stacked on the upper surface of the first power supply terminal 220 to which it is connected. In this way, the power supply cable 400 is not easily detached from the connected first power supply terminal 220 due to its own gravity, and the connection between the power supply cable 400 and the first power supply terminal 220 is relatively stable.

[0068] In some examples, the power connector 200 includes two rows of first power supply terminals 220 arranged side by side vertically, and each row of first power supply terminals 220 is connected to a power supply cable 400.

[0069] In other examples, the power connector 200 includes two rows of first power supply terminals 220 arranged side by side vertically, where one row of first power supply terminals 220 is connected to a power supply cable 400, and the other row of first power supply terminals 220 is not connected to a power supply cable 400.

[0070] In other examples, the power connector 200 may also include only one row of first power supply terminals 220.

[0071] As Figure 4 shown, the surface of the gold finger insertion portion 21 has power contact pads (not shown) for electrically contacting the power supply terminals, and the base 210 has a slot (not shown) for inserting the gold finger insertion portion 21 of the power module 20. The first power supply terminal 220 may include a first power supply elastic segment 221 and a first power supply pin segment 222. At least a portion of the first power supply elastic segment 221 is located in the slot and is used for electrically contacting the corresponding power contact pads on the gold finger insertion portion 21 inserted into the slot. One end of the first power supply elastic segment 221 is connected to one end of the first power supply pin segment 222. One end of the power supply cable 400 used for electrically connecting to the power connector 200 is fixed to and electrically connected to the first power supply pin segment 222. That is to say, the first power supply pin segment 222 is used for fixing and electrically connecting to the power supply cable 400. In this way, after the gold finger insertion portion 21 is inserted into the slot of the power connector 200, the power module 20 can be electrically connected to the power supply cable 400, so that the power module 20 can supply power to the load 300 through the power supply cable 400.

[0072] In the example where the power supply cable 400 is adhesively fixed to the first power supply terminal 220 through conductive adhesive, the power supply cable 400 is adhesively fixed to the first power supply pin segment 222 through conductive adhesive.

[0073] In an example where the power supply cable 400 is fixedly welded to the first power supply terminal 220, the power supply cable 400 is fixedly welded to the first power supply pin segment 222.

[0074] In some examples, the first power supply pin segment 222 is exposed outside the base 210, and the power supply cable 400 is fixed and electrically connected to the first power supply pin segment 222 outside the base 210. That is to say, one end of the power supply cable 400 for electrically connecting to the power connector 200 is connected to the first power supply terminal 220 outside the base 210. In this way, the power connector 200 can be connected to various types of power supply cables 400, which is convenient for selecting the power supply cable 400 according to the load 300 to be connected when the power connector 200 is installed on the circuit board 100 and electrically connecting the power supply cable 400 to the power connector 200.

[0075] In some examples where the first power supply pin segment 222 is exposed outside the base 210, the base 210 includes a first side surface and a second side surface. The first side surface faces the circuit board 100, the second side surface has a different orientation from the first side surface, and the first power supply pin segment 222 protrudes from the second side surface. In this way, after the power connector 200 is installed on the circuit board 100, it is more convenient to connect the power supply cable 400 to the first power supply pin segment 222.

[0076] Exemplarily, the second side surface can be adjacent to the first side surface, or the second side surface can be opposite to the first side surface.

[0077] In some examples where the first power supply pin segment 222 is exposed outside the base 210, the base 210 has a window for exposing the first power supply pin segment 222. In this way, after the power connector 200 is installed on the circuit board 100, it is more convenient to connect the power supply cable 400 to the first power supply pin segment 222. At this time, the first power supply pin segment 222 can protrude from the first side surface, which is convenient for modifying the existing power connector.

[0078] It should be noted that the window is an opening formed on the base 210 for exposing the first power supply pin segment 222 that was originally buried in the base 210.

[0079] In some examples, the first power supply terminal 220 is fixed and electrically connected to the power supply cable 400 inside the base 210. That is to say, the connection between the first power supply terminal 220 and the power supply cable 400 is buried inside the base 210. At this time, the first power supply pin segment 222 is located inside the base 210, and the power supply cable 400 is fixed and electrically connected to the first power supply pin segment 222 inside the base 210. In this way, it is not easy for the devices and users outside the base 210 to accidentally touch the connection between the power supply cable 400 and the first power supply terminal 220.

[0080] Continue to refer to Figure 3, in a possible implementation, the power supply cable 400 includes a power line and a connection terminal 430. The connection terminal 430 is provided at one end of the power line and is electrically connected to the power line. The other end of the power line is used to be electrically connected to the load 300, so that the connection terminal 430 is electrically connected to the load 300 through the electrically connected power line. The connection terminal 430 is fixedly connected to the first power terminal 220 and is electrically connected to the first power terminal 220, so that the first power terminal 220 can supply power to the load 300 through the electrically connected connection terminal 430 and power line. In this way, the area of the part of the power supply cable 400 used for connecting to the first power terminal 220 can be made larger, the connection between the power supply cable 400 and the first power terminal 220 is more convenient, and the connection is more stable after connection.

[0081] In an example where the power supply cable 400 is adhesively fixed to the first power terminal 220 through a conductive adhesive, the connection terminal 430 is adhesively fixed to the first power terminal 220 through a conductive adhesive. Specifically, the connection terminal 430 is adhesively fixed to the first power pin segment 222 through a conductive adhesive.

Figure 6 For Figure 5 This is a schematic diagram of another perspective view of the connection terminal provided in Figure 7 This is a schematic diagram before the connection terminal of the power supply cable of a computing device provided by an embodiment of the present application is installed.

[0085] As Figures 5 - 8 shown, and referring to Figure 4 , the power line includes a wire core 420 and an epidermis 410 covering the surface of the wire core 420. The wire core 420 is made of a conductive material, the epidermis 410 is made of an insulating material, and the end of the wire core 420 penetrates through the epidermis 410. The connection terminal 430 is fixed to and electrically connected to one end of the wire core 420.

[0086] Exemplarily, the wire core 420 can be made of materials such as copper, silver, aluminum, etc.

[0087] In some examples, the connection terminal 430 includes a wire core connection sleeve 432 and a terminal connection portion 431 connected to one end of the wire core connection sleeve 432. The other end of the wire core connection sleeve 432 is for one end of the wire core 420 to be inserted. One end of the wire core 420 is sleeved inside the wire core connection sleeve 432. The inner wall of the wire core connection sleeve 432 clamps and fixes the end portion of the wire core 420 sleeved therein. The inner wall of the wire core connection sleeve 432 is electrically connected to the end portion of the wire core 420 sleeved therein. The other end of the wire core 420 is for electrically connecting to the load 300. The terminal connection portion 431 is for being fixedly and electrically connected to the first power terminal 220, so that the first power terminal 220 is electrically connected to the load 300 through the wire core 420.

[0088] Exemplarily, the terminal connection portion 431 can be a sheet-like structure.

[0089] Exemplarily, the inner wall of the wire core connection sleeve 432 can be adhesively fixed to the end portion of the wire core 420 sleeved therein through a conductive adhesive.

[0090] Exemplarily, the inner wall of the wire core connection sleeve 432 can be in interference fit with the end portion of the wire core 420 sleeved therein.

[0091] Exemplarily, the connection terminal 430 can be a cold-pressed terminal. After one end of the wire core 420 is inserted into the wire core connection sleeve 432, the wire core connection sleeve 432 can be deformed by extruding the wire core connection sleeve 432 to press and fix the end portion of the wire core 420 inside the wire core connection sleeve 432.

[0092] In some examples, the connection terminal 430 can be fixedly welded to one end of the wire core 420.

[0093] Continue to refer to Figure 4 , an insulating sleeve 500 is sleeved outside the connection portion of the power supply cable 400 and the first power terminal 220. The inner wall of the insulating sleeve 500 is for pressing and fixing the connection portion of the power supply cable 400 and the first power terminal 220. Specifically, the outer sides of the first power pin segment 222 and the connection terminal 430 are sleeved with the insulating sleeve 500. The inner wall of the insulating sleeve 500 is for pressing and fixing the whole formed after the first power pin segment 222 and the connection terminal 430 are fixedly connected. In this way, it is beneficial to the insulation isolation of the connection portion of the power supply cable 400 and the first power terminal 220. In addition, after the connection portion of the power supply cable 400 and the first power terminal 220 is pressed by the insulating sleeve 500, the stability after the power supply cable 400 and the first power terminal 220 are connected can be better. In addition, by fixing the insulating sleeve 500 in a pressing manner, the fixing of the insulating sleeve 500 is also relatively convenient.

[0094] Exemplarily, the insulating sleeve 500 is made of an elastic material. After the insulating sleeve 500 is sleeved on the connection part between the power supply cable 400 and the first power terminal 220, the connection part between the power supply cable 400 and the first power terminal 220 presses the insulating sleeve 500, causing the insulating sleeve 500 to undergo elastic deformation.

[0095] Exemplarily, one end of the skin 410 close to the connection terminal 430 is sleeved inside the insulating sleeve 500. In this way, the insulation isolation effect at the connection part between the power supply cable 400 and the first power terminal 220 is better.

[0096] Figure 9 It is a schematic diagram of an insulating sleeve of a computing device provided by an embodiment of the present application.

[0097] As Figure 9 shown, and referring to Figure 4 , the insulating sleeve 500 includes a first section 510, a second section 520, and a third section 530. The first section 510 is sleeved on the outside of the skin 410, and the inner wall of the first section 510 is in clearance fit with the skin 410. The second section 520 is used to be sleeved on the outside of the connection terminal 430 and the first power pin section 222. The inner wall of the second section 520 is used to tightly press and fix the whole formed after fixedly connecting the first power pin section 222 and the connection terminal 430, so that the insulating sleeve 500 is fixed at the connection part between the first power pin section 222 and the connection terminal 430. The third section 530 is located between the first section 510 and the second section 520, and the first section 510 and the second section 520 are connected by the third section 530. The first section 510 can be a circular sleeve section, and the second section 520 can be a square sleeve section. The inner diameter of the first section 510 is less than at least one of the width and height of the inner cavity of the second section 520. The inner wall of the third section 530 includes an inclined surface structure, and the inner walls of the first section 510 and the second section 520 are transitioned through the inner wall of the third section 530. Before the connection terminal 430 is fixedly connected to the first power terminal 220, the first section 510, the second section 520, and the third section 530 can all be sleeved on the outside of the skin 410, and the first section 510, the second section 520, and the third section 530 can slide along the surface of the skin 410. After the connection terminal 430 is fixedly connected to the first power pin section 222, the first section 510, the second section 520, and the third section 530 can be slid in the direction away from the end of the power supply cable 400 for connecting the load 300, so as to sleeve the second section 520 on the outside of the connection terminal 430 and the first power pin section 222. The second section 520 tightly presses the whole formed after fixedly connecting the connection terminal 430 and the first power pin section 222. The whole formed after the connection terminal 430 is fixedly connected to the first power pin section 222 can press the second section 520 and cause the second section 520 to deform.

[0098] Figure 10An upward view schematic diagram of the connection between the power supply cable of a computing device provided by an embodiment of the present application and the first power terminal.

[0099] As Figure 10 shown, in some examples, the computing device includes at least one power supply cable 400, and the power connector 200 includes at least two first power terminals 220. At least one power supply cable 400 is fixed to and electrically connected to at least two first power terminals 220. In this way, multiple first power terminals 220 can supply power to the load 300 through the same power supply cable 400. When the current required by the load 300 is relatively large, the number of power supply cables 400 used can be reduced, making the connection between the power supply cable 400 and the power connector 200 more convenient. In addition, after the number of power supply cables 400 is reduced, the cost of the computing device can also be reduced. Moreover, after the number of power supply cables 400 is reduced, it is also easier to route the cables outside the circuit board 100.

[0100] Exemplarily, the terminal connection portion 431 of the connection terminal 430 is fixed to and electrically connected to the first power pin segments 222 of at least two first power terminals 220.

[0101] Exemplarily, each row of first power terminals 220 may include a plurality of first power terminals 220 arranged at intervals, and the power supply cable 400 connected to at least two first power terminals 220 may be fixed to and electrically connected to at least two adjacent first power terminals 220 located in the same row.

[0102] Continuing to refer to Figure 3 , in some examples, the power connector 200 further includes signal terminals 230, and the signal terminals 230 are fixed to and electrically connected to the circuit board 100. For example, the signal terminals 230 may be soldered to the circuit board 100. The signal terminals 230 may be electrically connected to the load 300 through signal traces 120 located in the conductive layer, so that signal interaction can occur between the power connector 200 and the load 300. That is to say, the electrical signals emitted by at least one of the power connector 200 and the load 300 can be transmitted to the other of the power connector 200 and the load 300 through the signal traces 120 located in the conductive layer. In this way, it is convenient to transmit the signals between the power connector 200 and the load 300.

[0103] Exemplarily, the signals transmitted in the signal terminals 230 and the signal traces 120 may be power management signals.

[0104] Figure 11 A schematic diagram of the connection between the signal terminal of a main board and the circuit board provided by an embodiment of the present application.

[0105] As Figure 11As shown, the signal terminal 230 is fixedly connected to the base 210. The surface of the gold finger insertion portion 21 also has signal contact pads (not shown) for making electrical contact with the signal terminal 230. The signal terminal 230 may include a signal spring segment 231 and a signal pin segment 232. At least a part of the signal spring segment 231 is located within the slot and is used for making electrical contact with the corresponding signal contact pads on the gold finger insertion portion 21 inserted into the slot. One end of the signal spring segment 231 is connected to one end of the signal pin segment 232. The other end of the signal pin segment 232 extends out of the base 210 and is used for being inserted into the corresponding signal via 130 on the circuit board 100. The inner wall of the signal via 130 is fixed to and electrically connected to the inserted signal pin segment 232. The signal via 130 is electrically connected to the signal trace 120 located in the conductive layer, such that the signal terminal 230 can be electrically connected to the signal trace 120 through the inserted signal via 130. In this way, it is convenient to fix the power connector 200 to the circuit board 100 through the signal terminal 230.

[0106] Exemplarily, the signal via 130 can be fixed to and electrically connected to the inserted signal pin segment 232 by means of conductive adhesive bonding, soldering, interference fit, etc.

[0107] Exemplarily, the signal pin segment 232 can protrude from the first side surface.

[0108] Figure 12 It is a schematic diagram of another computing device provided by an embodiment of the present application.

[0109] As Figure 12 shown, the housing 30 may include a housing body 31 and a housing cover 32. The housing cover 32 is lid-connected to the housing body 31. A chamber for installing the circuit board 100 and the load 300 is formed between the housing cover 32 and the housing body 31. The circuit board 100 is fixedly connected to the housing body 31 within the chamber. At least a part of the power connector 200 is located within the chamber formed between the housing cover 32 and the housing body 31. The side of the power connector 200 facing away from the circuit board 100 faces the housing cover 32, and the housing cover 32 presses the power connector 200 onto the circuit board 100. In this way, the stability after connection between the power connector 200 and the circuit board 100 can be relatively good.

[0110] In some examples, the inner wall of the housing cover 32 abuts against the side of the power connector 200 facing away from the circuit board 100.

[0111] Figure 13 It is a schematic diagram of another computing device provided by an embodiment of the present application.

[0112] As Figure 13As shown, in some examples, a portion of the inner wall of the housing cover 32 opposite to the power connector 200 has a protrusion 33. The side of the protrusion 33 facing away from the housing cover 32 abuts against the side of the power connector 200 facing away from the circuit board 100. The housing cover 32 can press the power connector 200 onto the circuit board 100 through the protrusion 33.

[0113] Exemplarily, the protrusion 33 can be an integral structure with the housing cover 32.

[0115] As Figure 14 As shown, in some examples, a gland member 40 can be provided between the housing cover 32 and the power connector 200. One side of the gland member 40 abuts against the housing cover 32, and the other side of the gland member 40 abuts against the power connector 200. The housing cover 32 can press the power connector 200 onto the circuit board 100 through the gland member 40. In this way, it is convenient to improve the stability after the connection between the power connector 200 and the circuit board 100 in a housing 32 with a relatively high height.

[0116] Exemplarily, the gland member 40 can include, but is not limited to, a hard disk, an input / output (I / O) module, etc.

[0117] In some examples, the power connector 200 further includes an auxiliary connection structure 240 for fixedly connecting the power connector 200 to the circuit board 100. Specifically, the auxiliary connection structure 240 is used to fixedly connect the base 210 and the circuit board 100. In this way, it is beneficial to improve the stability after the connection between the power connector 200 and the circuit board 100.

[0118] It should be noted that the auxiliary connection structure 240 refers to a connection structure for fixedly connecting the power connector 200 to the circuit board 100, rather than for electrically connecting the power connector 200 to the circuit board 100.

[0119] Figure 15 Schematic diagram of another computing device provided by an embodiment of the present application.

[0120] As Figure 15 As shown, in some examples, the auxiliary connection structure 240 can include a plurality of connection pins 241. One end of the connection pin 241 is fixedly connected to the base 210, and the other end of the connection pin 241 is fixedly connected to the circuit board 100. In this way, the connection positions between the power connector 200 and the circuit board 100 are increased, and the stability after the connection between the circuit board 100 and the power connector 200 can be improved.

[0121] Exemplarily, the connection pin 241 can be soldered and fixed to a corresponding pad (not shown) provided on the surface of the circuit board 100, and the connection pin 241 is insulated from the traces on the circuit board 100.

[0122] In some examples, the auxiliary connection structure 240 can include a locking structure, and a mating portion that cooperates with the locking structure can be provided on the circuit board 100. The locking structure cooperates with the mating portion to fixedly connect the circuit board 100 to the base 210 (not shown). In this way, the connection between the circuit board 100 and the base 210 can be made more stable after connection.

[0123] In some examples, the auxiliary connection structure 240 can include a fastener connection structure, and the base 210 is fixedly connected to the circuit board 100 through the fastener connection structure (not shown). In this way, the connection between the circuit board 100 and the base 210 can be made more stable after connection.

[0124] Exemplarily, the fastener connection structure can include, but is not limited to, a screw connection structure, a pin connection structure, etc.

[0125] In some examples, the power connector 200 further includes a ground terminal, and the ground terminal is fixedly connected to the base 210. The surface of the gold finger insertion portion 21 further has a ground contact piece for making electrical contact with the ground terminal. The ground terminal includes a ground elastic section and a ground pin section. At least part of the ground elastic section is located in the slot and is used for making electrical contact with the corresponding ground contact piece on the gold finger insertion portion 21 inserted into the slot. One end of the ground elastic section is connected to one end of the ground pin section, and the other end of the ground pin section extends out of the base 210 and is used for being inserted into a corresponding ground via hole on the circuit board 100. The hole wall of the ground via hole is fixed and electrically connected to the inserted ground pin section, and the ground via hole is electrically connected to the ground trace located in the conductive layer, so that the ground terminal can be electrically connected to the ground trace through the inserted ground via hole (not shown). In this way, the power connector 200 can be grounded for protection. In addition, the connection position between the power connector 200 and the circuit board 100 is also increased, and the stability of the power connector 200 after being connected to the circuit board 100 can be made better.

In addition to being used to supply power to the load 300 electrically connected to the power supply cable 400 through the power supply cable 400, the power connector 200 is also used to supply power to the load 300 electrically connected to the power supply trace 110 through the power supply trace 110.

[0130] In the example in which part of the load 300 is electrically connected to the power connector 200 via the power supply cable 400, and part of the load 300 is electrically connected to the power connector 200 via the power trace 110 located on the inner conductive layer, the power terminal also includes a second power terminal (not shown) for being inserted into a power via of the circuit board 100, and part of the load 300 is electrically connected to the second power terminal via the power trace 110 located on the inner conductive layer. Specifically, the second power terminal is fixedly connected to the base 210, and the second power terminal includes a second power spring segment and a second power pin segment. At least a portion of the second power spring segment is located in the slot and is used to electrically contact the corresponding power contact on the gold finger plug-in portion 21 inserted into the slot. One end of the second power spring segment is connected to one end of the second power pin segment, and the other end of the second power pin segment extends out of the base 210 and is used to be inserted into the corresponding power via (not shown) on the circuit board 100. The hole wall of the power via is fixed and electrically connected to the second power pin segment inserted therein, and the power via is electrically connected to the power trace 110 located on the conductive layer, so that the second power terminal can be electrically connected to the power trace 110 through the power via inserted therein.

[0131] The connection method between the power supply cable 400 and the load 300 may refer to the connection method between the power supply cable 400 and the power connector 200. Specifically, the load 300 may have a circuit board connector, one end of the power supply cable 400 away from the power connector 200 is fixedly connected to the circuit board connector, and the signal trace 120 may be electrically connected to the circuit board connector.
