[0002] With the continuous development of cloud computing and big data in recent years, the improvement of our living standards has indirectly led to an increasing demand for server performance, and the requirements for the performance of the Central Processing Unit (CPU), the number of memories, and the number of hard disks have been greatly increased. With the increasing demand for servers, the space occupied by devices such as CPUs, memories, and hard disks on the server motherboard is also getting larger and larger, and the space for the remaining functional modules is very limited. Especially for the electronic fuse (eFuse) protection module, many products have abandoned the hot pluggable function of some external board cards due to space limitations. Once a problem occurs in each functional module inside the server, the system can only be shut down to repair the faulty device, and such a practice undoubtedly reduces the reliability and maintainability of the server and the data center.

Detailed implementation manners

[0036] To facilitate a clearer understanding of the embodiments of the present invention, some related background knowledge is introduced as follows.

[0037] Figure 1 It is a schematic structural diagram of an eFuse protection module provided by the related art. As Figure 1 shown, in the related art, an electronic fuse connects a load and a power supply through a field effect transistor (FET) and a resistor. The eFuse monitors the magnitude of the current by detecting the potential difference across the resistor. When the potential difference across the resistor exceeds a preset voltage value, the control logic disconnects the FET and cuts off the current path. The FET on the current conduction path needs to have a very low on-resistance to ensure very low conduction loss.

[0038] There are many external signals in the eFuse protection module in the related art. The eFuse chip itself and the peripheral resistors and capacitors occupy a large amount of space on the main board, making it more difficult to allocate the already limited board-level space.

[0039] Moreover, the configuration flexibility of the eFuse protection module in the related art is not high. For the same product, different configurations are selected according to different application scenarios. Since the existing eFuse protection module configuration method is to select components by installing or not installing components during the production of PCBA (Printed Circuit Board Assembly, which refers to the entire process of mounting components on a printed circuit board (PCB) blank through SMT or through dual in-line package (DIP) plug-in), in some application scenarios that do not require this protection module, due to sharing the same main board during production, the space on the main board still has to be occupied by the eFuse protection module.

[0040] To overcome the above-mentioned deficiencies, the present invention provides a connector, an electronic fuse device, and a board. By arranging the connector on the board, it is possible to avoid configuring an eFuse chip and its peripheral circuits on the board, effectively reducing the occupation of the board area, and the electronic fuse device can be selected as needed, increasing the flexibility of product configuration.

[0041] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without creative efforts shall fall within the protection scope of the present invention.

[0042] Figure 2 is a schematic structural diagram of the connector provided by the present invention, as Figure 2 shown, the connector includes a first conductive connector 201, a second conductive connector 202, and an elastic component 203;

[0043] The first conductive connector 201 and the second conductive connector 202 are oppositely arranged on the board 204;

[0044] The first end of the first conductive connector 201 is electrically connected to the power supply end of the board 204, and the second end of the first conductive connector 201 has a first conductive extension 2011 extending towards the second conductive connector 202;

[0045] The first end of the second conductive connector 202 is electrically connected to the load end of the board 204, and the second end of the second conductive connector 202 has a second conductive extension 2021 extending towards the first conductive connector 201;

[0046] An opening is formed between the first conductive extension 2011 and the second conductive extension 2021. The first conductive connector 201, the second conductive connector 202, and the board 204 form a groove area with the opening, and the protruding part of the electronic fuse device can be inserted into the groove area through the opening;

[0047] The elastic component 203 is arranged in the groove area. The first end of the elastic component 203 is fixedly connected to the board 204, and the second end of the elastic component 203 has conductivity. In the case where the protruding part is not inserted into the groove area, the second end of the elastic component 203 abuts against the opening;

[0048] A first conductive slot 2012 is provided on the first conductive extension 2011, and a second conductive slot 2022 is provided on the second conductive extension 2021. When the protruding portion is inserted into the groove area, the first conductive plug and the second conductive plug of the electronic fuse device can be correspondingly inserted into the first conductive slot 2012 and the second conductive slot 2022, and the second end of the elastic component 203 is separated from the opening.

[0049] Specifically, by providing a connector on the board 204, the connector includes a first conductive connection member 201, a second conductive connection member 202, and an elastic component 203. An opening is formed between the first conductive extension 2011 and the second conductive extension 2021. The first conductive connection member 201, the second conductive connection member 202, and the board 204 can form a groove area with an opening. The protruding portion of the electronic fuse device can be inserted into the groove area through the opening, and the elastic component 203 is disposed in the groove area.

[0050] When the board 204 does not require the hot pluggable function, the protruding portion of the electronic fuse device is not inserted into the groove area, the second end of the elastic component 203 abuts against the opening, and the second end of the elastic component 203 has conductivity, which can conduct the first conductive extension 2011 and the second conductive connection member 202. The power supply end of the board 204 can be electrically connected to the load end of the board 204 through the second end of the elastic component 203, that is, a first conductive path can be formed between the power supply end of the board 204 and the load end of the board 204. This first conductive path starts from the power supply end of the board 204, passes through the first conductive connection member 201, the second end of the elastic component 203, and the second conductive connection member 202, and terminates at the load end of the board 204.

[0051] When the board 204 requires the hot pluggable function, the protruding portion of the electronic fuse device is inserted into the groove area, the second end of the elastic component 203 is separated from the opening, and the power supply end of the board 204 can be electrically connected to the load end of the board 204 through the electronic fuse device, that is, a second conductive path can be formed between the power supply end of the board 204 and the load end of the board 204. This second conductive path starts from the power supply end of the board 204, passes through the first conductive connection member 201, the electronic fuse device, and the second conductive connection member 202, and terminates at the load end of the board 204.

[0052] It can be understood that taking the electronic fuse device as an external device of the board 204 can avoid configuring an eFuse chip and its peripheral circuits on the board 204, and can effectively reduce the occupation of the area of the board 204.

[0053] It can be understood that when the board 204 requires hot pluggable function, the electronic fuse device can be plugged into the connector, and when the board 204 does not require hot pluggable function, the electronic fuse device can be unplugged from the connector, so that the electronic fuse device can be selected for the board 204 as needed, and the flexibility of product configuration can be increased.

[0054] Optionally, Figure 3 is a side view of the electronic fuse device provided by the present invention plugged into the connector, Figure 4 is a top view of the electronic fuse device provided by the present invention plugged into the connector, as Figure 3 and Figure 4 shown, when the board 204 requires hot pluggable function, the protrusion 5013 of the electronic fuse device 500 is inserted into the groove area, the second end of the elastic component 203 is separated from the opening, and the power supply end of the board 204 can be electrically connected to the load end of the board 204 through the electronic fuse device, that is, a second conductive path can be formed between the power supply end of the board 204 and the load end of the board 204. The second conductive path starts from the power supply end of the board 204, passes through the first end of the first conductive connector 201, the first conductive slot 2012, the first conductive plug 5011 of the electronic fuse device, the first electronic fuse chip module 502, the second conductive plug 5012 of the electronic fuse device, the second conductive slot 2022 and the first end of the second conductive connector 202, and terminates at the load end of the board 204.

[0055] Optionally, the first end of the first conductive connector 201 can be welded to the power supply end of the board 204, and the first end of the second conductive connector 202 can be welded to the load end of the board 204.

[0056] For the connector provided by the present invention, by providing a connector on the board, when the board does not require hot pluggable function, the power supply end of the board can be electrically connected to the load end of the board through the second end of the elastic component, and when the board requires hot pluggable function, the power supply end of the board can be electrically connected to the load end of the board through the electronic fuse device, which can avoid configuring an eFuse chip and its peripheral circuits on the board, effectively reduce the occupation of the board area, and can select the electronic fuse device as needed, increasing the flexibility of product configuration.

[0057] Optionally, for a connector provided by the present invention, the second conductive slot 2022 includes a first conductive interface and a first data communication interface, and the first conductive interface is electrically connected to the load end of the board through the second conductive extension 2021;

[0058] A first data communication line is provided inside the second conductive connector 202. A first end of the first data communication line is connected to the first data communication interface, and a second end of the first data communication line is connected to a second data communication interface of the board 204.

[0059] Specifically, in the case where the board 204 requires a hot-swap function, the protruding portion of the electronic fuse device is inserted into the groove area, and the first conductive plug and the second conductive plug of the electronic fuse device can be correspondingly inserted into the first conductive slot 2012 and the second conductive slot 2022. The second conductive plug may include a second conductive interface and a third data communication interface. The second conductive interface may be electrically connected to the first conductive interface, and the third data communication interface may be connected to the first data communication interface, capable of forming a communication path between the electronic fuse device and the board 204.

[0060] It can be understood that the data communication of this communication path can be two-way. The first data flow direction of this communication path starts from the third data communication interface of the electronic fuse device, passes through the first data communication interface and the first data communication line, and then reaches the second data communication interface of the board 204; the second data flow direction of this communication path starts from the second data communication interface of the board 204, passes through the first data communication line and the first data communication interface, and then reaches the third data communication interface of the electronic fuse device.

[0061] Therefore, based on the formation of a communication path between the electronic fuse device and the board, the electronic fuse device can report monitoring data to the board, and the board can issue control instructions to the electronic fuse device, capable of supporting the automatic management of the electronic fuse device by the board.

[0062] Optionally, according to a connector provided by the present invention, the first data communication interface and the second data communication interface are power management bus interfaces.

[0063] Specifically, based on the formation of a communication path between the electronic fuse device and the board 204, the first data communication interface and the second data communication interface may be power management bus (PMBus) interfaces. The electronic fuse device can report various monitoring information to the baseboard management controller (BMC) on the board 204, including but not limited to monitoring information such as input and output voltages, output currents, and chip temperatures. The BMC on the board 204 can perform real-time management of the electronic fuse device based on these monitoring information.

[0064] For example, as Figure 3As shown, the data communication interface can be a PMBus interface. When a communication path is formed between the electronic fuse device and the board 204, for the BMC on the board 204, if it determines an abnormal power consumption based on the monitoring information, the BMC can send a shutdown instruction to the electronic fuse device through this communication path. After receiving the shutdown instruction, the electronic fuse device can disconnect the conductive path between the power supply terminal and the load terminal of the board 204.

[0065] Therefore, the first data communication interface and the second data communication interface can be PMBus interfaces. When a communication path is formed between the electronic fuse device and the board, the board can perform real-time management on the electronic fuse device.

[0066] Optionally, according to a connector provided by the present invention, the elastic component 203 includes an elastic member and a conductive sheet. The first end of the elastic member is fixedly connected to the board, and the second end of the elastic member is fixedly connected to the conductive sheet. When the protruding portion is not inserted into the groove area, the conductive sheet abuts against the opening.

[0067] Specifically, when the board 204 does not require the hot-swap function, the protruding portion of the electronic fuse device is not inserted into the groove area, and the conductive sheet of the elastic component 203 abuts against the opening. The conductive sheet of the elastic component 203 has conductivity and can conduct the first conductive extension 2011 and the second conductive connector 202. The power supply terminal of the board 204 can be electrically connected to the load terminal of the board 204 through the conductive sheet, that is, a first conductive path can be formed between the power supply terminal and the load terminal of the board 204. This first conductive path starts from the power supply terminal of the board 204, passes through the first conductive connector 201, the conductive sheet, and the second conductive connector 202, and terminates at the load terminal of the board 204.

[0068] When the board 204 requires the hot-swap function, the protruding portion of the electronic fuse device is inserted into the groove area, and the conductive sheet of the elastic component 203 is separated from the opening. The power supply terminal of the board 204 can be electrically connected to the load terminal of the board 204 through the electronic fuse device, that is, a second conductive path can be formed between the power supply terminal and the load terminal of the board 204. This second conductive path starts from the power supply terminal of the board 204, passes through the first conductive connector 201, the electronic fuse device, and the second conductive connector 202, and terminates at the load terminal of the board 204.

[0069] It can be understood that the conductive sheet can be made of a conductor with a very small resistance to ensure the minimum voltage drop between the source end voltage and the load end voltage.

[0070] Therefore, when the board needs the hot-swap function, the electronic fuse device can be plugged into the connector, and the conductive sheet is separated from the opening. When the board does not need the hot-swap function, the electronic fuse device can be pulled out from the connector, and the conductive sheet abuts against the opening, enabling the electronic fuse device to be selected as needed for the board and increasing the flexibility of product configuration.

[0071] Optionally, for a connector provided by the present invention, the elastic member includes a first spring and a second spring. The first end of the first spring is fixedly connected to the board, the second end of the first spring is fixedly connected to the first end of the conductive sheet, the first end of the second spring is fixedly connected to the board, and the second end of the second spring is fixedly connected to the second end of the conductive sheet.

[0072] Specifically, when the board 204 does not need the hot-swap function, the protruding portion of the electronic fuse device is not inserted into the groove area. The first spring can abut the first end of the conductive sheet against one side of the opening (for example, the side where the first conductive extension 2011 is located), and the second spring can abut the second end of the conductive sheet against the other side of the opening (for example, the side where the second conductive extension 2021 is located), so as to abut the conductive sheet of the elastic component 203 against the opening. The conductive sheet has conductivity and can conduct the first conductive extension 2011 and the second conductive connection member 202.

[0073] For the connector provided by the present invention, by providing a connector on the board, when the board does not need the hot-swap function, the power supply end of the board can be electrically connected to the load end of the board through the second end of the elastic component. When the board needs the hot-swap function, the power supply end of the board can be electrically connected to the load end of the board through the electronic fuse device, which can avoid configuring an eFuse chip and its peripheral circuits on the board, effectively reduce the occupation of the board area, and can select the electronic fuse device as needed, increasing the flexibility of product configuration.

[0074] Figure 5 is a schematic structural diagram of the electronic fuse device provided by the present invention, as Figure 5 shown, the electronic fuse device 500 includes: a carrier board 501 and a first electronic fuse chip module 502. The carrier board 501 is provided with a first conductive plug 5011, a second conductive plug 5012, and a protruding portion 5013;

[0075] The first conductive plug 5011 is electrically connected to the power supply end of the first electronic fuse chip module;

[0076] The second conductive plug 5012 is electrically connected to the load end of the first electronic fuse chip module 502;

[0077] The protruding portion 5013 can be inserted into the groove area of the connector through the opening of the connector. When the protruding portion 5013 is inserted into the groove area, the first conductive plug 5011 and the second conductive plug 5012 can be correspondingly inserted into the first conductive slot 2012 and the second conductive slot 2022 of the connector, and the second end of the elastic component 203 of the connector is separated from the opening.

[0078] Specifically, when the board 204 requires a hot-swap function, the protruding portion 5013 of the electronic fuse device is inserted into the groove area, and the second end of the elastic component 203 is separated from the opening. The power supply end of the board 204 can be electrically connected to the load end of the board 204 through the electronic fuse device, that is, a second conductive path can be formed between the power supply end and the load end of the board 204. This second conductive path starts from the power supply end of the board 204, passes through the first conductive connection member 201, the first conductive plug 5011 of the electronic fuse device, the power supply end of the first electronic fuse chip module 502, the load end of the first electronic fuse chip module 502, the second conductive plug 5012 of the electronic fuse device, and the second conductive connection member 202, and terminates at the load end of the board 204.

[0079] Optionally, Figure 6 is a schematic structural diagram of the electronic fuse chip module provided by the present invention. As Figure 6 shown, the electronic fuse device can be used as an external device of the board 204, and all eFuse chip-level designs can be completed on the electronic fuse device. For example, eFuse peripheral circuits, including but not limited to resistors and capacitors that need to be configured such as overcurrent protection points, overvoltage or undervoltage protection points, and soft start time, are all placed on the electronic fuse device, which can effectively reduce the space occupied by the eFuse module on the main board in the board-level power topology.

[0080] It can be understood that when the board 204 requires a hot-swap function, the electronic fuse device can be plugged into the connector, and when the board 204 does not require a hot-swap function, the electronic fuse device can be unplugged from the connector, which can select the electronic fuse device for the board 204 as needed and increase the flexibility of product configuration.

[0081] The electronic fuse device provided by the present invention can be plugged into the connector when the board requires hot plugging and unplugging functions. The power supply end of the board can be electrically connected to the load end of the board through the electronic fuse device. When the board does not require hot plugging and unplugging functions, the electronic fuse device can be unplugged from the connector, and the power supply end of the board can be electrically connected to the load end of the board through the second end of the elastic component of the connector, which can avoid configuring an eFuse chip and its peripheral circuits on the board, effectively reduce the occupation of the board area, and can select the electronic fuse device as needed, increasing the flexibility of product configuration.

[0082] Optionally, for an electronic fuse device provided by the present invention, the second conductive plug 5012 includes a second conductive interface and a third data communication interface, and the second conductive interface is electrically connected to the load end of the first electronic fuse chip module 502 through the carrier board 501;

[0083] A second data communication line is provided in the carrier board 501. The first end of the second data communication line is connected to the third data communication interface, and the second end of the second data communication line is connected to the fourth data communication interface of the first electronic fuse chip module 502.

[0084] Specifically, when the board 204 requires hot plugging and unplugging functions, the protruding portion 5013 of the electronic fuse device is inserted into the groove area, and the first conductive plug 5011 and the second conductive plug 5012 of the electronic fuse device can be correspondingly inserted into the first conductive slot 2012 and the second conductive slot 2022. The second conductive interface can be electrically connected to the first conductive interface, forming a second conductive path between the power supply end and the load end of the board 204. This second conductive path starts from the power supply end of the board 204, passes through the first conductive connector 201, the first conductive plug 5011 of the electronic fuse device, the power supply end of the first electronic fuse chip module 502, the load end of the first electronic fuse chip module 502, the second conductive interface of the second conductive plug 5012, and the second conductive connector 202, and terminates at the load end of the board 204.

[0087] Therefore, based on the formation of a communication path between the electronic insurance device and the board, the electronic insurance device can report monitoring data to the board, and the board can issue control instructions to the electronic insurance device, which can support the automatic management of the electronic insurance device by the board.

[0088] Optionally, according to an electronic insurance device provided by the present invention, the third data communication interface and the fourth data communication interface are power management bus interfaces.

[0089] Specifically, based on the formation of a communication path between the electronic insurance device and the board 204, the third data communication interface and the fourth data communication interface can be PMBus interfaces. The electronic insurance device can report various monitoring information to the BMC on the board 204, including but not limited to monitoring information such as input and output voltages, output currents, and chip temperatures. The BMC on the board 204 can perform real-time management of the electronic insurance device based on these monitoring information.

[0090] Therefore, the third data communication interface and the fourth data communication interface can be PMBus interfaces. In the case of forming a communication path between the electronic insurance device and the board, the board can perform real-time management of the electronic insurance device.

[0091] Optionally, according to an electronic insurance device provided by the present invention, Figure 7 is a schematic structural diagram of the parallel connection of the electronic insurance chip modules provided by the present invention.

The first conductive plug 5011 is electrically connected to the power supply ends of the second electronic insurance chip modules, and the second conductive plug 5012 is electrically connected to the load ends of the second electronic insurance chip modules 503.

[0092] Specifically, in order to adapt to the working current required by the board 204, one or more second electronic insurance chip modules 503 can be connected in parallel with the first electronic insurance chip module 502 to increase the upper limit of the current that the electronic insurance device can pass through.

[0093] The electronic insurance device provided by the present invention can be plugged into the connector when the board needs the hot pluggable function. The power supply end of the board can be electrically connected to the load end of the board through the electronic insurance device. When the board does not need the hot pluggable function, the electronic insurance device can be unplugged from the connector, and the power supply end of the board can be electrically connected to the load end of the board through the second end of the elastic component of the connector, which can avoid configuring the eFuse chip and its peripheral circuit on the board, effectively reduce the occupation of the board area, and can select the electronic insurance device as needed, increasing the flexibility of product configuration.

[0094] The present invention also provides a board, which includes any one of the above-mentioned connectors and any one of the above-mentioned electronic insurance devices.

[0095] Specifically, when the board needs the hot pluggable function, the electronic insurance device can be plugged into the connector, and the power supply end of the board can be electrically connected to the load end of the board through the electronic insurance device. When the board does not need the hot pluggable function, the electronic insurance device can be unplugged from the connector, and the power supply end of the board can be electrically connected to the load end of the board through the second end of the elastic component of the connector.

[0096] For the board provided by the present invention, by providing a connector on the board, the connector includes a first conductive connection member, a second conductive connection member and an elastic component. An opening is formed between the first conductive extension portion and the second conductive extension portion. The first conductive connection member, the second conductive connection member and the board can form a groove area with an opening. The protrusion of the electronic insurance device can be inserted into the groove area through the opening. The elastic component is arranged in the groove area. When the board does not need the hot pluggable function, the protrusion of the electronic insurance device is not inserted into the groove area, and the second end of the elastic component abuts against the opening. The power supply end of the board can be electrically connected to the load end of the board through the second end of the elastic component. When the board needs the hot pluggable function, the protrusion of the electronic insurance device is inserted into the groove area, and the second end of the elastic component is separated from the opening. The power supply end of the board can be electrically connected to the load end of the board through the electronic insurance device, which can avoid configuring the eFuse chip and its peripheral circuit on the board, effectively reduce the occupation of the board area, and can select the electronic insurance device as needed, increasing the flexibility of product configuration.
