[0006] Summary of the Invention

[0007] The embodiments of the present application provide a motherboard, a computing device, and a power connector, which can reduce the size of the circuit board of the motherboard.

[0008] In a first aspect, embodiments of the present application provide a motherboard comprising a circuit board, a power connector, and a load. The power connector and the load are both disposed on the circuit board. The power connector includes power terminals, which are configured to be fixedly secured to and electrically connected to a power supply cable located external to the circuit board. The power terminals are configured to supply power to the load via the power supply cable.

[0009] The mainboard provided in the embodiment of the present application can be supplied with power by the power connector to the load through the power supply cable located outside the circuit board, which can reduce the setting of the power supply lines on the circuit board, or even eliminate the need to set the power supply lines on the circuit board. 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, thereby reducing the length or width dimensions of the circuit board, or reducing the number of conductive layers of the circuit board, so that the size of the circuit board can be smaller. In addition, after supplying power to the load through the power supply cable outside the circuit board, the current flowing through the circuit board becomes less, and the circuit board is less likely to overheat. 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. Furthermore, there is no need to set up adapter connectors, adapter plates and other devices between the power supply cable and the power terminal, so there is no current loss caused by the adapter, and the structure is relatively simple, and the production and maintenance costs are low.

The power pin segment protrudes from the second side surface, or the base includes a window exposing the power pin segment. This facilitates connecting a power cable to the power connector after the power connector is mounted on the circuit board.

[0012] In a possible implementation of the mainboard provided in the first aspect, the power connector further includes an auxiliary connection structure for fixing the power connector to the circuit board, thereby improving the stability of the connection between the power connector and the circuit board.

In this way, the connection between the power cable and the power terminal is less likely to be accidentally touched, the connection is more convenient, and the stability after connection is improved.

[0016] In a possible implementation of the computing device provided in the second aspect, at least one power supply cable is fixed to and electrically connected to at least two power terminals, so that when the current required by the load is large, the number of power supply cables used can be reduced.

[0017] In one possible implementation of the computing device provided in the second aspect, a portion of the power cable is superimposed on an upper surface of the power terminal, and the portion of the power cable superimposed on the upper surface of the power terminal is fixed to and electrically connected to the power terminal. Thus, the power cable and the power terminal are more stable after being connected.

[0018] In one possible implementation of the computing device provided in the second aspect, the computing device further includes a housing and a housing cover, the housing cover being attached to the housing body. A chamber for mounting a circuit board and a load is formed between the housing cover and the housing body, and the circuit board is fixedly connected to the housing body within the chamber. At least a portion of the power connector is located within the chamber, with the side of the power connector facing away from the circuit board facing the housing cover, and the housing cover presses the power connector against the circuit board.

DETAILED DESCRIPTION

[0039] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application. The implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0040] 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.

[0041] FIG1 is a schematic diagram of a computing device provided in an embodiment of the present application.

[0042] As shown in FIG1 , in an embodiment of the present application, a computing device includes a power supply unit (PSU) 20 and a motherboard 10. The motherboard 10 includes a circuit board 100, a power connector 200, and a load 300. The load 300 and the power connector 200 are both disposed on the surface of the circuit board 100, and the circuit board 100 can be used to support the load 300 and the power connector 200. The load 300 is electrically connected to the power connector 200, which is used to electrically connect to the power module 20, so that the power module 20 can be electrically connected to the load 300 via the power connector 200. The power module 20 can be electrically connected to a power supply device such as a distribution box or to the mains electricity, so that the power supply device such as the distribution box or the mains electricity can supply power to the load 300 via the power module 20. For example, the power module 20 can have a gold finger connector 21, which can be plugged into the power connector 200 to secure and electrically connect the power module 20 to the power connector 200.

[0043] The power module 20 can adjust the current from the power supply equipment such as the distribution box or the mains 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 AC power, the power module 20 can convert the DC power from the power supply equipment such as the distribution box into the AC power required by the load 300, and then output it to the load 300. For another example, when the current required by the load 300 is DC power, the power module 20 can convert the AC power from the power supply equipment such as the distribution box or the mains into the DC power required by the load 300, and then output it to the load 300. For another example, when the voltage of the current from the power supply equipment such as the distribution box or the mains is higher or lower than the voltage of the current required by the load 300, the power module 20 can adjust the voltage of the current from the power supply equipment such as the distribution box or the mains to the voltage required by the load 300, and then output it to the load 300.

[0044] In the embodiment of the present application, the computing device may further include a housing 30 , the circuit board 100 and the load 300 may both be disposed within the housing 30 , and the circuit board 100 may be fixedly connected to an inner wall of the housing 30 .

[0045] In some examples, the power module 20 and the power connector 200 are disposed in the housing 30 , and the power module 20 is connected to the power connector 200 in the housing 30 .

[0046] In other examples, the power module 20 can be arranged outside the shell 30, and the shell 30 has a wall hole connecting the inner cavity of the shell 30 and the outside. The power connector 200 is arranged in the wall hole, so that part of the power connector 200 is located inside the shell 30 and part is located outside the shell 30. The circuit board 100 is connected to the part of the power connector 200 located inside the shell 30, and the power module 20 is used to be connected to the part of the power connector 200 located outside the shell 30 (not shown).

[0047] Illustratively, one or more loads 300 may be disposed on the surface of the circuit board 100 .

[0048] For example, any load 300 disposed on the surface of the circuit board 100 may include, but is not limited to, a processor, memory, a card, a fan, a hard disk, etc. The processor may include, but is not limited to, a central processing unit (CPU), a graphics processing unit (GPU), a data processing unit (DPU), etc.

[0049] For example, two power connectors 200 can be set on the surface of the circuit board 100, each power connector 200 can be used to electrically connect to a power module 20, and each power connector 200 can be electrically connected to all loads 300, so that when one of the power connectors 200 or the power module 20 electrically connected to the power connector 200 fails, power can be supplied to the load 300 through the other power connector 200 and the power module 20 electrically connected to the power connector 200.

[0050] For example, the circuit board 100 may include multiple conductive layers (not shown) and an insulating layer (not shown) located between two adjacent conductive layers, wherein the two adjacent conductive layers are connected via the insulating layer therebetween. The multiple conductive layers may include surface conductive layers located on both sides of the circuit board 100 in the thickness direction, and an inner conductive layer located between the two surface conductive layers on both sides of the circuit board 100.

[0051] In the related art, power connectors installed on the surface of a circuit board and loads are often electrically connected via power traces located on an inner conductive layer. Due to safety isolation requirements, a certain distance is required between the power traces and other conductive structures. Consequently, the large number of power traces installed within the circuit board results in a larger circuit board size. As computing device performance continues to improve, load power consumption continues to increase, requiring ever-increasing currents to flow through the power traces. To meet the high current requirements of these power-hungry loads, increasing the width and thickness of the power traces is often employed to improve their current-carrying capacity. However, increasing the width and thickness of the power traces further increases the circuit board's dimensions in at least one of its length and width, or increases the number of conductive layers, further increasing the size of the circuit board. Furthermore, current flowing through the power traces in the conductive layer generates heat, making the circuit board susceptible to overheating. Furthermore, when the power connector supplies power to the load through the power traces, the current-carrying cross-section of the power traces is small, resulting in significant current losses during transmission.

[0052] FIG2 is a schematic diagram of another computing device provided in an embodiment of the present application.

[0053] Based on this, as shown in FIG2 , 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 via 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 via 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 via the power supply cable 400 disposed outside the circuit board 100. This can reduce the number of power traces 110 disposed on the circuit board 100, or even eliminate the need for power traces 110 on the circuit board 100. With fewer power traces 110 disposed on the circuit board 100, the arrangement density of other conductive structures disposed on the circuit board 100 can be increased, thereby reducing the length or width of the circuit board 100, or reducing the number of conductive layers on the circuit board 100. This can result in a smaller size for the circuit board 100. Furthermore, after power is supplied to at least part of the load via the power supply cable 400 external to the circuit board 100, the current flowing through the circuit board 100 decreases, making the circuit board 100 less susceptible to overheating. Furthermore, the current flow cross-section of the power supply cable 400 is not restricted by the circuit board 100, allowing the cross-section of the power supply cable 400 to be larger, thereby reducing current loss when the power connector 200 supplies power to the load 300 via the power supply cable 400.

[0054] FIG3 is a schematic diagram of another computing device provided in an embodiment of the present application.

[0055] As shown in FIG3 , in an embodiment of the present application, a power cable 400 is fixedly connected to a power connector 200. Specifically, the power connector 200 includes a base 210 and a power terminal. The base 210 is made of an insulating material and is fixedly connected to the circuit board 100. The power terminal is fixedly connected to the base 210, and the power module 20 is electrically connected to the power terminal. The power terminal includes a first power terminal 220 for connecting to the power cable 400. The power 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 cable 400 through the power cable 400. The first power terminal 220 is used to supply power to the load 300 electrically connected to the power cable 400 through the power cable 400, so that the power module 20 can supply power to the load 300 electrically connected to the power cable 400 through the first power terminal 220 and the power cable 300. Thus, compared to a solution in which the power cable 400 is electrically connected to the power connector 200 via an adapter plate or other connector, there is no current loss caused by the adapter between the power cable 400 and the first power terminal 220, and the current transmission loss between the power cable 400 and the first power terminal 220 is relatively small. Furthermore, since no other connectors or adapter plates are required, the production and maintenance costs of the computing device can be reduced.

[0056] In some examples, the power cable 400 is bonded and fixed to the first power terminal 220 by conductive adhesive, so that the power cable 400 is electrically connected to the bonded first power terminal 220. In this way, the power cable 400 is more convenient to connect to the first power terminal 220.

[0057] In some examples, the power cable 400 is welded to the first power terminal 220 to electrically connect the power cable 400 to the welded first power terminal 220. This reduces the impedance at the connection between the power cable 400 and the first power terminal 220, thereby reducing the voltage drop between the power cable 400 and the first power terminal 220 and current loss during transmission between the power cable 400 and the first power terminal 220. Furthermore, the stability of the fixed connection between the power cable 400 and the first power terminal 220 is less affected by environmental factors such as temperature, resulting in a relatively stable connection between the power cable 400 and the first power terminal 220.

[0058] For example, one end of the power supply cable 400 may be welded to the first power terminal 220 by ultrasonic welding, laser welding, or the like.

[0059] FIG4 is a schematic diagram of the connection between a power connector and a power supply cable of a computing device provided in an embodiment of the present application.

[0060] As shown in Figure 4 , a portion of the power cable 400 overlaps the upper surface of the first power terminal 220. The portion of the power cable 400 that overlaps the upper surface of the first power terminal 220 is fixed to and electrically connected to the first power terminal 220. In other words, the portion of the power cable 400 that is connected to the first power terminal 220 overlaps the upper surface of the first power terminal 220 to which it is connected. This makes it less likely that the power cable 400 will detach from the connected first power terminal 220 due to its own weight, and the power cable 400 is more securely connected to the first power terminal 220.

[0061] In some examples, the power connector 200 includes two rows of first power terminals 220 arranged side by side, and each row of first power terminals 220 is connected to a power supply cable 400 .

[0062] In other examples, the power connector 200 includes two rows of first power terminals 220 arranged side by side, one row of first power terminals 220 is connected to the power cable 400 , and the other row of first power terminals 220 is not connected to the power cable 400 .

[0063] In other examples, the power connector 200 may also include only one row of first power terminals 220 .

[0064] As shown in Figure 4, the surface of the gold finger connector 21 has power contacts (not shown) for electrically contacting the power terminal. The base 210 has a slot (not shown) for inserting the gold finger connector 21 of the power module 20. The first power terminal 220 may include a first power spring segment 221 and a first power pin segment 222. At least a portion of the first power spring segment 221 is located within the slot and is configured to electrically contact a corresponding power contact on the gold finger connector 21 when inserted into the slot. One end of the first power spring segment 221 is connected to one end of the first power pin segment 222. The end of the power cable 400, which is intended for electrical connection to the power connector 200, is fixed to and electrically connected to the first power pin segment 222. In other words, the first power pin segment 222 is configured to be fixed to and electrically connected to the power cable 400. Thus, when the gold finger connector 21 is inserted into the slot of the power connector 200, the power module 20 is electrically connected to the power cable 400, allowing the power module 20 to supply power to the load 300 via the power cable 400.

[0065] In the example where the power supply cable 400 is bonded and fixed to the first power terminal 220 by means of conductive adhesive, the power supply cable 400 is bonded and fixed to the first power pin segment 222 by means of conductive adhesive.

[0066] In the example where the power supply cable 400 is fixed to the first power terminal 220 by welding, the power supply cable 400 is fixed to the first power pin segment 222 by welding.

[0067] In some examples, the first power pin segment 222 is exposed outside the base 210, and the power cable 400 is secured to and electrically connected to the first power pin segment 222 outside the base 210. In other words, the end of the power cable 400 for electrical connection to the power connector 200 is connected to the first power terminal 220 outside the base 210. This allows the power connector 200 to connect to a variety of power cables 400 models. This facilitates selecting a power cable 400 based on the load 300 to be connected when the power connector 200 is mounted on the circuit board 100, and electrically connecting the power cable 400 to the power connector 200.

[0068] In some examples where the first power 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, and the second side surface is oriented differently from the first side surface. The first power pin segment 222 protrudes from the second side surface. This facilitates connection between the power cable 400 and the first power pin segment 222 after the power connector 200 is mounted on the circuit board 100.

[0069] Illustratively, the second side surface may be adjacent to the first side surface, or the second side surface may be opposite to the first side surface.

[0070] In some examples where the first power pin segment 222 is exposed outside the base 210, the base 210 may include a window to expose the first power pin segment 222. This facilitates connecting the power cable 400 to the first power pin segment 222 after the power connector 200 is mounted on the circuit board 100. In this case, the first power pin segment 222 may protrude from the first side surface, facilitating retrofitting existing power connectors.

[0071] It should be noted that the window is an opening formed on the base 210 for exposing the first power pin segment 222 originally embedded in the base 210 .

[0072] In some examples, the first power terminal 220 is fixed and electrically connected to the power cable 400 within the base 210. That is, the connection between the first power terminal 220 and the power cable 400 is embedded within the base 210. In this case, the first power pin segment 222 is located within the base 210, and the power cable 400 is fixed and electrically connected to the first power pin segment 222 within the base 210. This makes it difficult for devices outside the base 210 or users to accidentally touch the connection between the power cable 400 and the first power terminal 220.

[0073] Continuing with FIG3 , in one possible implementation, the power supply cable 400 includes a power cord and a connection terminal 430. The connection terminal 430 is disposed at one end of the power cord and electrically connected to the power cord. The other end of the power cord is used to electrically connect to the load 300, such that the connection terminal 430 is electrically connected to the load 300 via the electrically connected power cord. The connection terminal 430 is fixedly connected to the first power terminal 220 and electrically connected to the first power terminal 220, such that the first power terminal 220 can supply power to the load 300 via the electrically connected connection terminal 430 and the power cord. In this way, the area of ​​the portion of the power supply cable 400 used for connection to the first power terminal 220 can be larger, making the connection between the power supply cable 400 and the first power terminal 220 more convenient and more stable.

[0074] In the example where the power supply cable 400 is bonded and fixed to the first power terminal 220 by conductive adhesive, the connection terminal 430 is bonded and fixed to the first power terminal 220 by conductive adhesive. Specifically, the connection terminal 430 is bonded and fixed to the first power pin segment 222 by conductive adhesive.

[0075] In the example where the power supply cable 400 is fixed to the first power terminal 220 by welding, the connection terminal 430 is fixed to the first power terminal 220 by welding. Specifically, the connection terminal 430 is fixed to the first power pin segment 222 by welding.

[0076] In an example where the portion of the power supply cable 400 for connection to the first power terminal 220 overlaps the upper surface of the first power terminal 220 to which it is connected, the connection terminal 430 overlaps the upper surface of the connected first power terminal 220. Specifically, the connection terminal 430 overlaps the upper surface of the connected first power pin segment 222.

[0078] As shown in Figures 5 to 8, and referring to Figure 4, the power cord includes a core 420 and a skin 410 covering the surface of the core 420. The core 420 is made of a conductive material, and the skin 410 is made of an insulating material. The end of the core 420 passes through the skin 410, and the connecting terminal 430 is fixed to one end of the core 420 and electrically connected.

[0079] For example, the core 420 may be made of copper, silver, aluminum, or other materials.

[0080] In some examples, the connection terminal 430 includes a core connection sleeve 432 and a terminal connection portion 431 connected to one end of the core connection sleeve 432. The other end of the core connection sleeve 432 is used for inserting one end of the core 420. One end of the core 420 is sleeved within the core connection sleeve 432. The inner wall of the core connection sleeve 432 clamps and fixes the end of the core 420 sleeved therein. The inner wall of the core connection sleeve 432 is electrically connected to the end of the core 420 sleeved therein. The other end of the core 420 is used to be electrically connected to the load 300. The terminal connection portion 431 is used to be fixed to 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 core 420.

[0081] Illustratively, the terminal connection portion 431 may be a sheet-like structure.

[0082] For example, the inner wall of the wire core connecting sleeve 432 can be bonded and fixed to the end of the wire core 420 sleeved therein by means of conductive glue.

[0083] For example, the inner wall of the wire core connecting sleeve 432 may be interference fit with the end of the wire core 420 sleeved therein.

[0084] Exemplarily, the connecting terminal 430 can be a cold-pressed terminal. After one end of the wire core 420 is inserted into the wire core connecting sleeve 432, the wire core connecting sleeve 432 can be squeezed to deform the wire core connecting sleeve 432 to tighten and fix the end of the wire core 420 in the wire core connecting sleeve 432.

[0085] In some examples, the connection terminal 430 may be fixed to one end of the wire core 420 by welding.

[0086] Continuing with FIG4 , an insulating sleeve 500 is provided on the outer side of the connection between the power supply cable 400 and the first power terminal 220. The inner wall of the insulating sleeve 500 is used to compress and secure the connection between the power supply cable 400 and the first power terminal 220. Specifically, the insulating sleeve 500 is provided on the outer side of the first power pin segment 222 and the connection terminal 430. The inner wall of the insulating sleeve 500 is used to compress and secure the entire structure formed after the first power pin segment 222 and the connection terminal 430 are fixedly connected. This facilitates insulation isolation at the connection between the power supply cable 400 and the first power terminal 220. In addition, by compressing the connection between the power supply cable 400 and the first power terminal 220 with the insulating sleeve 500, the stability of the power supply cable 400 and the first power terminal 220 can be improved. Furthermore, by fixing the insulating sleeve 500 by compression, the fixing of the insulating sleeve 500 is also more convenient.

[0087] Exemplarily, the insulating sleeve 500 is made of elastic material. After the insulating sleeve 500 is sleeved on the connection between the power supply cable 400 and the first power terminal 220, the connection between the power supply cable 400 and the first power terminal 220 squeezes the insulating sleeve 500 to cause the insulating sleeve 500 to undergo elastic deformation.

[0088] For example, the end of the skin 410 close to the connection terminal 430 is sleeved in the insulating sleeve 500. In this way, the insulation isolation effect at the connection between the power supply cable 400 and the first power terminal 220 is better.

[0089] FIG9 is a schematic diagram of an insulating sleeve of a computing device provided in an embodiment of the present application.

[0090] As shown in FIG9 and referring to FIG4, 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 with the skin 410. The second section 520 is used to sleeve on the outside of the connecting terminal 430 and the first power pin section 222. The inner wall of the second section 520 is used to press and fix the first power pin section 222 and the connecting terminal 430 together to form a whole, so that the insulating sleeve 500 is fixed on the first power pin section 222. At the connection point between the foot section 222 and the connecting terminal 430, the third section 530 is located between the first section 510 and the second section 520. The first section 510 and the second section 520 are connected through the third section 530. The first section 510 can be a round sleeve section, and the second section 520 can be a square sleeve section. The inner diameter of the first section 510 is smaller 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 a slope structure, and the inner wall of the first section 510 and the inner wall of the second section 520 are transitioned through the inner wall of the third section 530. Before the connecting 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 epidermis 410, and the first section 510, the second section 520 and the third section 530 can slide along the surface of the epidermis 410. After the connecting 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 a direction away from the end of the power supply cable 400 for connecting the load 300, so that the second section 520 is sleeved on the outside of the connecting terminal 430 and the first power pin section 222. The second section 520 presses the whole formed after the connecting terminal 430 and the first power pin section 222 are fixedly connected. The whole formed after the connecting terminal 430 and the first power pin section 222 are fixedly connected can squeeze the second section 520 and cause the second section 520 to deform.

[0091] FIG10 is a bottom view schematically showing a connection point between a power supply cable and a first power terminal of a computing device provided in an embodiment of the present application.

[0092] As shown in FIG10 , in some examples, the computing device includes at least one power cable 400, and the power connector 200 includes at least two first power terminals 220. The at least one power cable 400 is fixed to and electrically connected to the at least two first power terminals 220. In this way, multiple first power terminals 220 can supply power to the load 300 via the same power cable 400. When the current required by the load 300 is large, the number of power cables 400 used can be reduced, making the connection between the power cables 400 and the power connector 200 more convenient. Furthermore, reducing the number of power cables 400 can also reduce the cost of the computing device. Furthermore, reducing the number of power cables 400 also makes it easier to route wiring outside the circuit board 100.

[0093] Illustratively, 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 .

[0094] Illustratively, each row of first power terminals 220 may include a plurality of first power terminals 220 arranged at intervals, and a power supply cable 400 connected to at least two first power terminals 220 may be fixed and electrically connected to at least two adjacent first power terminals 220 in the same row.

[0095] Continuing with FIG. 3 , in some examples, the power connector 200 further includes a signal terminal 230 . The signal terminal 230 is fixed to and electrically connected to the circuit board 100 . For example, the signal terminal 230 can be soldered to the circuit board 100 . The signal terminal 230 can be electrically connected to the load 300 via the signal trace 120 located on the conductive layer, thereby enabling signal exchange between the power connector 200 and the load 300 . In other words, an electrical signal 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 via the signal trace 120 located on the conductive layer. This facilitates signal transmission between the power connector 200 and the load 300 .

[0096] For example, the signal transmitted through the signal terminal 230 and the signal trace 120 may be a power management signal.

[0097] FIG11 is a schematic diagram of the connection between a signal terminal of a mainboard and a circuit board provided in an embodiment of the present application.

[0098] As shown in FIG11 , the signal terminal 230 is fixedly connected to the base 210. The surface of the gold finger plug-in portion 21 also has a signal contact (not shown) for electrically contacting the signal terminal 230. The signal terminal 230 may include a signal flare segment 231 and a signal pin segment 232. At least a portion of the signal flare segment 231 is located in the slot and is used to electrically contact the corresponding signal contact on the gold finger plug-in portion 21 inserted into the slot. One end of the signal flare 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 to be inserted into the corresponding signal via 130 on the circuit board 100. The hole wall of the signal via 130 is fixed and electrically connected to the signal pin segment 232 inserted therein. The signal via 130 is electrically connected to the signal trace 120 located on the conductive layer, so that the signal terminal 230 can be electrically connected to the signal trace 120 through the signal via 130 in which it is inserted. In this way, it is convenient to fix the power connector 200 on the circuit board 100 via the signal terminals 230 .

[0099] For example, the signal via 130 can be fixed and electrically connected to the signal pin segment 232 inserted therein by means of conductive adhesive bonding, welding, interference fit, etc.

[0100] For example, the signal pin segment 232 may protrude from the first side surface.

[0101] FIG12 is a schematic diagram of another computing device provided in an embodiment of the present application.

[0102] As shown in FIG12 , the housing 30 may include a body 31 and a cover 32 . The cover 32 is attached to the body 31 . A chamber for mounting the circuit board 100 and the load 300 is formed between the cover 32 and the body 31 . The circuit board 100 is fixedly connected to the body 31 within the chamber. At least a portion of the power connector 200 is located within the chamber formed between the cover 32 and the body 31 . The side of the power connector 200 facing away from the circuit board 100 faces the cover 32 . The cover 32 presses the power connector 200 against the circuit board 100 . This ensures better stability of the connection between the power connector 200 and the circuit board 100 .

[0103] In some examples, an inner wall of the housing cover 32 abuts against a side of the power connector 200 facing away from the circuit board 100 .

[0104] FIG13 is a schematic diagram of another computing device provided in an embodiment of the present application.

[0105] As shown in Figure 13, in some examples, the inner wall of the shell cover 32 opposite to the power connector 200 has a protrusion 33, and the side of the protrusion 33 facing away from the shell cover 32 abuts against the side of the power connector 200 facing away from the circuit board 100. The shell cover 32 can press the power connector 200 onto the circuit board 100 through the protrusion 33.

[0106] For example, the protrusion 33 and the shell cover 32 may be an integral structure.

[0108] As shown in FIG14 , in some examples, a pressure cover component 40 may be provided between the housing cover 32 and the power connector 200. One side of the pressure cover component 40 abuts against the housing cover 32, and the other side of the pressure cover component 40 abuts against the power connector 200. The housing cover 32 can press the power connector 200 against the circuit board 100 through the pressure cover component 40. This facilitates improving the stability of the power connector 200 after connection to the circuit board 100 in a housing 32 having a relatively high height.

[0109] Exemplarily, the cover component 40 may include but is not limited to a hard disk, an input / output (I / O) module, and the like.

[0110] In some examples, the power connector 200 further includes an auxiliary connection structure 240, which is used to securely connect the power connector 200 to the circuit board 100. Specifically, the auxiliary connection structure 240 is used to securely connect the base 210 to the circuit board 100. This helps improve the stability of the connection between the power connector 200 and the circuit board 100.

[0111] It should be noted that the auxiliary connection structure 240 refers to a connection structure used for fixed connection between the power connector 200 and the circuit board 100 , but not for electrical connection between the power connector 200 and the circuit board 100 .

[0112] FIG15 is a schematic diagram of another computing device provided in an embodiment of the present application.

[0113] As shown in Figure 15, in some examples, the auxiliary connection structure 240 may 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 position between the power connector 200 and the circuit board 100 is increased, and the stability of the circuit board 100 after the power connector 200 is connected can be improved.

[0114] Illustratively, the connecting pins 241 may be fixed by welding to corresponding pads (not shown) provided on the surface of the circuit board 100 , and the connecting pins 241 are insulated from the traces on the circuit board 100 .

[0115] In some examples, the auxiliary connection structure 240 may include a locking structure, and the circuit board 100 may be provided with a mating portion that mates with the locking structure. The locking structure mates with the mating portion to securely connect the circuit board 100 to the base 210 (not shown). This allows for a more stable connection between the circuit board 100 and the base 210.

[0116] In some examples, the auxiliary connection structure 240 may include a fastener connection structure, and the base 210 is fixedly connected to the circuit board 100 via the fastener connection structure (not shown). In this way, the connection between the circuit board 100 and the base 210 can be more stable.

[0118] In some examples, the power connector 200 also includes a ground terminal, which is fixedly connected to the base 210. The surface of the gold finger plug-in portion 21 also has a ground contact for electrically contacting the ground terminal. The ground terminal includes a ground spring segment and a ground pin segment. At least a portion of the ground spring segment is located in the slot and is used to electrically contact the corresponding ground contact on the gold finger plug-in portion 21 inserted into the slot. One end of the ground spring segment is connected to one end of the ground pin segment. The other end of the ground pin segment extends out of the base 210 and is used to be inserted into the corresponding ground via on the circuit board 100. The hole wall of the ground via is fixed and electrically connected to the ground pin segment inserted therein. The ground via is electrically connected to the ground trace located on the conductive layer, so that the ground terminal can be electrically connected to the ground trace through the ground via in which it is inserted (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 increased, which can improve the stability of the power connector 200 after being connected to the circuit board 100.

In addition to supplying 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 line 110 through the power line 110.

[0123] In the example in which part of the load 300 is electrically connected to the power connector 200 through the power supply cable 400, and part of the load 300 is electrically connected to the power connector 200 through 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 the power via of the circuit board 100, and part of the load 300 is electrically connected to the second power terminal through the power trace 110 located on the inner conductive layer.

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.
