Description

Technical Field

[0001] This application relates to the field of connector technology, and in particular to a connector, a connection assembly, a circuit board assembly, and an electronic device. Background Technology

[0002] Currently, server architectures are generally moving towards standardization, modularization, and openness. Servers are composed of multiple standardized modules that can be freely combined. These standardized modules can be motherboard modules, I / O expansion board modules, hard drive backplane modules, etc. In related technologies, one of these modules is electrically connected to an external power supply and then connected to other modules via cables. For example, the motherboard module is electrically connected to an external power supply, and its power connector is connected to the power connector of the hard drive backplane module via a cable, thus supplying power to the hard drive backplane module through the cable. However, cables require cable management space. Therefore, modules that support flexible cable connections are used in servers with larger internal spaces. Modules supporting flexible cable connections cannot be directly applied to servers with smaller internal spaces. In such cases, it is necessary to redevelop modules suitable for smaller internal spaces, leading to higher server costs. Summary of the Invention

[0003] This application provides a connector, a connection component, a circuit board assembly, and an electronic device. The male connector supports both flexible cable connections and hard copper busbar connections, making the power connector compatible with both flexible cable connections and hard copper busbar connections. The circuit board assembly can be applied to different scenarios and reduces the cost of electronic devices.

[0004] In a first aspect, embodiments of this application provide a male connector for connecting to a female connector and electrically connecting to a power connector. The male connector includes a housing and a male current-passing terminal. The housing includes a receiving cavity, a first opening, and a second opening, which respectively communicate between the interior and exterior of the receiving cavity. At least a portion of the male current-passing terminal is located inside the receiving cavity. A first end of the male current-passing terminal has a socket for insertion into one of the female current-passing terminals of the female connector. The first end of the male current-passing terminal is inserted into and electrically connected to the female current-passing terminal through the first opening, and a second end of the male current-passing terminal is electrically connected to the power connector through the second opening.

[0005] In this embodiment, the power connector can be a cable or a copper busbar, etc. The male current-carrying terminal can be electrically connected to the cable or copper busbar. The male current-carrying terminal supports both flexible cable connection and hard copper busbar connection, so that the male connector supports both flexible cable connection and hard copper busbar connection. Thus, the power connector formed by the male connector and the female connector supports both flexible cable connection and hard copper busbar connection. Consequently, the circuit board assembly formed by the female connector and the circuit board assembly can be applied to different scenarios without redesigning the power connector and circuit board, thereby reducing the cost of electronic devices.

[0006] In some possible implementations, the male connector also includes an anti-rotation structure disposed between the male current-passing terminal and the housing, which is used to prevent the male current-passing terminal from rotating.

[0007] In this implementation, when rotational force is applied to the male current-carrying terminal, the anti-rotation structure prevents the male current-carrying terminal from rotating, thus preventing it from colliding with the surrounding plastic walls and avoiding problems such as damage, cracking, and deformation of the housing. Furthermore, the anti-rotation structure also further ensures that the male current-carrying terminal can be connected to cables or copper busbars, enabling it to support flexible cable connections or rigid copper busbar connections.

[0008] In some possible implementations, the anti-rotation structure includes a limiting part and a mating part. The mating part is disposed in the housing, and the limiting part is disposed in the male current-passing terminal. Along the circumference of the first opening, the limiting part is used to abut against the mating part to prevent the male current-passing terminal from rotating.

[0009] In this implementation, when a rotational force is applied to the male current-passing terminal, the limiting part abuts against the mating part, preventing the male current-passing terminal from rotating, thus avoiding collision between the male current-passing terminal and the housing, and preventing problems such as damage, cracking, and deformation of the housing.

[0010] In some possible implementations, one of the limiting part and the mating part is a boss and the other is a groove for the boss to be inserted.

[0011] In this implementation, the assembly difficulty of the housing and the male current-passing terminal can be reduced by the cooperation of the groove and the boss, and the purpose of preventing the male current-passing terminal from rotating can be achieved.

[0012] In some possible implementations, the male connector also includes a limiting member, at least a portion of which is located inside the receiving cavity and fixedly connected to the housing. Along the axial direction of the first opening, the opposite ends of the male flow terminal abut against the limiting member and the inner wall of the receiving cavity, respectively.

[0013] In this implementation, because the two opposite ends of the male current-passing terminal abut against the limiting member and the inner wall of the receiving cavity respectively, the male current-passing terminal is clamped, preventing it from moving up and down along the axial direction of the first opening. This ensures that the relative positional relationship between the male current-passing terminal and the housing remains constant, allowing the male current-passing terminal to stably plug into and electrically connect with the female current-passing terminal when the male connector is connected to the female connector. Furthermore, when the cable is bent up and down or the copper busbar moves up and down, the male current-passing terminal will not move up and down along the axial direction of the first opening, ensuring that the male current-passing terminal supports both flexible cable connections and rigid copper busbar connections.

[0014] In some possible implementations, there are two limiting members, namely a first limiting member and a second limiting member. The male current-passing terminal includes a first current-passing part and a second current-passing part. The first current-passing part is used for electrical connection with the female current-passing terminal, and the second current-passing part is used for electrical connection with the power connector. Along the axial direction of the first opening, the opposite ends of the first current-passing part abut against the inner wall of the receiving cavity and the first limiting member, respectively. The opposite ends of the second current-passing part abut against the inner wall of the receiving cavity and the second limiting member, respectively.

[0015] In this implementation, vertical movement of the male current-carrying terminal is avoided, thus improving the overall limiting effect of the male current-carrying terminal.

[0016] In some possible implementations, the first end of the male current-passing terminal has a socket for insertion of the female current-passing terminal. The male connector also includes a resilient conductive element located inside the socket and electrically connected to the male current-passing terminal. When the first end of the male current-passing terminal is inserted into the female current-passing terminal, the resilient conductive element electrically connects the male current-passing terminal and the female current-passing terminal.

[0017] In this implementation, because the elastic conductive element is elastic, it will undergo elastic deformation after it comes into contact with the female current-carrying terminal, so that there is a force between the elastic conductive element and the female current-carrying terminal, ensuring that the two are in close contact and achieving a stable electrical connection.

[0018] In some possible implementations, the elastic conductive element is a crown spring. When the first end of the male current-passing terminal is inserted into the female current-passing terminal, the crown spring is sleeved on the female current-passing terminal and abuts against the female current-passing terminal along the radial direction of the insertion hole.

[0019] In this implementation, the crown spring's ability to store a large amount of energy in a small space contributes to a compact design. While providing the same spring force, the crown spring's outer diameter can be made smaller, helping to save space and ensure stable electrical contact with the female current-carrying terminal.

[0020] In some possible implementations, one of the housing and the outer shell of the female connector has a slot for mating with the other.

[0021] In this implementation, when the male connector and the female connector are plugged in, a portion of one of the housings and the shell is inserted into the slot of the other, thus achieving the insertion of the housing and the shell. This helps to improve the reliability of the connection between the male connector and the female connector, and also helps to insert one of the male current-passing terminals and the female current-passing terminals into the socket of the other, thereby increasing the insertion speed of the female connector and the male connector.

[0022] In some possible implementations, the housing includes a main body and an insertion part, the insertion part having a first opening for inserting into a slot in the housing, and the main body having a second opening.

[0023] In this implementation, the housing portion is inserted into the slot, which helps reduce the difficulty of assembling the housing and outer shell, and reduces the size of the male connector.

[0024] In some possible implementations, the male connector also includes a copper busbar connector, one end of which is electrically connected to the second end of the male current-passing terminal through a second opening, and the other end of which is located outside the receiving cavity and electrically connected to the power connector.

[0025] In this implementation, the male current-carrying terminal is electrically connected to the power connector via a copper busbar connector, which eliminates the need for the male connector and the power connector to be assembled into a single unit. The appropriate type of power connector (such as a cable or copper busbar) can be selected as needed, further improving the flexibility of the male connector.

[0026] Secondly, embodiments of this application provide a female connector for connecting to a male connector and to a circuit board. The female connector includes a housing and a female current-passing terminal. A portion of the female current-passing terminal is embedded inside the housing. A first end of the female current-passing terminal is used for electrical connection to the circuit board, and a second end of the female current-passing terminal has a socket for insertion into one of the male current-passing terminals of the male connector. The second end of the female current-passing terminal is used for insertion into and electrical connection with the male current-passing terminal.

[0027] In practical implementation, the female connector and the circuit board can be pre-assembled into a circuit board assembly. When the circuit board assembly is applied to different scenarios, a male connector that supports either flexible cable connections or rigid copper busbar connections can be selected based on the scenario conditions (such as space, current carrying capacity, etc.). For example, when the circuit board assembly is applied to a space-constrained scenario, a male connector with rigid copper busbar connections can be selected and plugged into the female connector for electrical connection, forming a power connector that supports rigid copper busbar connections. Alternatively, when the circuit board assembly is applied to a space-constrained scenario, a male connector with flexible cable connections can be selected and plugged into the female connector for electrical connection, forming a power connector that supports flexible cable connections.

[0028] In some possible implementations, one of the housing and the male connector housing has a slot for partial insertion of the other.

[0029] In this implementation, when the male connector and female connector are plugged in, a portion of one of the outer shell and housing is inserted into the slot of the other, achieving shell-to-housing insertion. This helps improve the reliability of the connection between the male and female connectors and facilitates the insertion of one of the male or female current-passing terminals into the other's socket, thereby increasing the plugging speed of the female and male connectors.

[0030] In some possible implementations, the housing has a slot for inserting a portion of the housing, with a portion of the female current-passing terminal located inside the slot and used for plugging into and electrically connecting with the male current-passing terminal.

[0031] In this implementation, the housing portion is inserted into the slot, which helps reduce the difficulty of assembling the housing and outer shell, and reduces the size of the male connector.

[0032] In some possible implementations, the female current-passing terminal includes a pin portion, an insert portion, and a connecting portion connected in sequence. The insert portion is embedded inside the housing, the connecting portion is located outside the housing and is electrically connected to the circuit board, and the pin portion is located outside the housing and is used to plug into and electrically connect to the male current-passing terminal.

[0033] In this implementation, when the male current-carrying terminal is inserted into the female current-carrying terminal, the pin portion extends into the cavity through the first opening and is inserted into the socket. The elastic conductive element is sleeved on the pin portion and abuts against the pin portion. The pin portion is electrically connected to the male current-carrying terminal through the elastic conductive element.

[0034] Thirdly, embodiments of this application provide a connection component, which includes a power connector and at least one male connector as described in any of the first aspects, wherein at least one end of the power connector is electrically connected to the male connector.

[0035] In this embodiment of the application, assembling the male connector and the power connector into a single unit helps to improve the assembly efficiency of electronic devices.

[0036] In some possible implementations, the power connector is a cable, with the male current-carrying terminal of the male connector electrically connected to the cable, or the copper busbar of the male connector electrically connected to the cable.

[0037] In this implementation, the cable can be directly or indirectly connected to the male current-carrying terminal to meet different needs.

[0038] Fourthly, embodiments of this application provide a circuit board assembly, which includes a circuit board and a female connector as described in any of the second aspects, the female connector being electrically connected to the circuit board.

[0039] In this embodiment, pre-assembling the female connector and the circuit board into a single unit helps improve the assembly efficiency of electronic devices. Furthermore, the circuit board assembly, when used with a male connector that supports flexible cable connections or rigid copper busbar connections, can be applied to various scenarios.

[0040] Fifthly, embodiments of this application provide a power connector, which includes a male connector according to any of the first aspects and a female connector according to any of the second aspects. The female connector has a female current-passing terminal for connecting to a circuit board, and the male connector has a male current-passing terminal for electrically connecting to a power connector. The male current-passing terminal is inserted into and electrically connected to the female current-passing terminal.

[0041] In this embodiment, the power connector supports both flexible cable connections and rigid copper busbar connections. The power connector does not limit the application of the circuit board assembly to different scenarios. When the circuit board assembly is applied to different scenarios, there is no need to redesign the power connector and the circuit board assembly, which improves the versatility and flexibility of the circuit board assembly and the power connector, reduces the cost of functional modules, and reduces the design cost of electronic devices.

[0042] In a sixth aspect, embodiments of this application provide an electronic device, which includes a circuit board, a power connector, and a power connector as described in the fifth aspect, wherein the female connector of the power connector is electrically connected to the circuit board, and the male connector of the power connector is electrically connected to the power connector.

[0075] The terminology used in the implementation section of this application is for the purpose of explaining specific embodiments of this application only, and is not intended to limit this application.

[0076] Currently, server architecture is generally moving towards standardization, modularization, and openness. Servers are composed of multiple standardized modules that can be freely combined. These standardized modules can be motherboard modules, I / O expansion board modules, hard drive backplane modules, etc. Because server form factors and configurations vary widely, a single standardized module may face a variety of application scenarios, such as servers with large internal spaces, servers with small internal spaces, or servers requiring high throughput. In related technologies, one of these modules is electrically connected to an external power supply and then connected to other modules via cables. For example, the motherboard module is electrically connected to an external power supply, and its power interface is connected to the power interface of the hard drive backplane module via a cable, thus supplying power to the hard drive backplane module through the cable.

[0077] When using a flexible cable to connect two modules, in some embodiments, both ends of the cable are pluggable power connectors. The cable is electrically connected to the circuit boards of modules such as the motherboard module and the hard drive backplane module through the power connectors. The cable can be bent arbitrarily, offering high flexibility. However, the contact impedance between the cable and the power connector is high, limiting its current carrying capacity. The cable requires cable management space, making it difficult to use in space-constrained scenarios; that is, the cable is typically used in scenarios with ample space. In other embodiments, one end of the cable is a pluggable power connector, and the other end is an OT terminal fixed with screws. This method can maintain some flexibility and achieve higher current carrying capacity, but because of the higher current carrying capacity, the cable is very thick, requiring even more cable management space and making it unsuitable for space-constrained scenarios.

[0078] In space-constrained scenarios, one implementation uses a copper busbar to rigidly connect the two modules. In some embodiments, one module uses a busbar, and the other uses a copper busbar, with the copper busbar connected to the busbar via contact. The two modules can be quickly connected or disconnected; however, the position between the two modules is relatively fixed, lacking flexibility, and the copper busbar is relatively small. In other embodiments, horseshoe terminals are used on the two modules, and a hard connection is achieved using screws on the copper busbar. The position of the two modules is relatively fixed, and screw fixation is required, which is also less flexible, and the copper busbar is relatively small.

[0079] In summary, because cables require space for cable management, modules supporting flexible cable connections are used in servers with larger internal spaces. They cannot be directly applied to servers with smaller internal spaces, requiring the development of new modules suitable for smaller spaces, thus increasing server costs. Similarly, hard connections on copper busbars are suitable for space-constrained scenarios. However, when high current carrying capacity is not required and space is ample, hard connection modules cannot be directly applied to such scenarios, necessitating the development of new modules supporting flexible connections, further increasing costs.

[0080] In view of this, embodiments of this application provide a male connector 100, a female connector 200, a power connector 300, a connection assembly, a circuit board assembly, and an electronic device. The male connector 100 supports both flexible and rigid connections, allowing the circuit board assembly to more flexibly adapt to different application scenarios. For example, when the circuit board assembly is used in a space-constrained scenario, the female connector 200 of the circuit board assembly connects to the male connector 100 that supports rigid connections; or when the circuit board assembly is used in a space-constrained scenario, the female connector 200 of the circuit board assembly connects to the male connector 100 that supports flexible connections. Therefore, the power connector 300, which is compatible with both flexible and rigid connections, increases the flexibility of the circuit board assembly, eliminating the need to redevelop the circuit board assembly for different application scenarios, reducing development costs, and lowering the cost of the electronic device.

[0081] This application provides an electronic device, which can be a server, switch, router, storage device, etc. When the electronic device is a server, it can specifically be a rack server, high-density server, etc. The following description uses a rack server as an example.

[0082] The electronic device may include a chassis, a power connector 400, and multiple functional modules. The multiple functional modules are located inside the chassis and may include a motherboard module, a hard drive backplane module, an I / O expansion board module, etc. At least one functional module includes a circuit board 500 and a power connector 300, which is electrically connected to the power connector 400. The power connector 400 is used to provide power between two functional modules.

[0083] The power connector 400 can be a cable, copper busbar, or other structure. There can be one or more power connectors 400. When there are multiple power connectors 400, at least two power connectors 400 can have the same structure, or any two power connectors 400 can have different structures.

[0084] Figure 1 A schematic diagram of a power connector provided for an embodiment of the application. Figure 2 for Figure 1 The diagram shows a cross-sectional view of the power connector mating with the power connector and circuit board.

[0085] like Figure 1 As shown, the power connector 300 includes a male connector 100 and a female connector 200. Wherein, as... Figure 1As shown, the female connector 200 is mounted on and electrically connected to the circuit board 500. The male connector 100 is inserted into and electrically connected to the female connector 200, and is also electrically connected to the power connector 400. The power connector 300 has a connected state and a disconnected state. When the power connector 300 is in the connected state, the male connector 100 and the female connector 200 are connected and electrically connected by insertion. When the power connector 300 is in the disconnected state, the male connector 100 and the female connector 200 are separated, not inserted, and not electrically connected.

[0086] Figure 3 for Figure 1 A schematic diagram showing the male connector and power connector forming a connection assembly. Figure 4 for Figure 1 The diagram shows the female connector and the circuit board forming a circuit board assembly.

[0087] In practice, the male connector 100 and the power connector 400 can be pre-assembled into a connection assembly (such as...). Figure 3 As shown), the female connector 200 and the circuit board 500 can also be pre-configured as a circuit board assembly (e.g., Figure 4 (As shown). By pre-assembling the male connector 100 and the power connector 400 into a single unit, and pre-assembling the female connector 200 and the circuit board 500 into a single unit, the assembly efficiency of electronic devices can be improved.

[0088] In the connection assembly, at least one end of the power connector 400 is electrically connected to a male connector 100. For example, the power connector 400 is a cable, one end of which is electrically connected to the male connector 100 and the other end is electrically connected to an OT terminal, or both ends of the cable are electrically connected to the male connector 100 respectively.

[0089] Figure 5 for Figure 1 An exploded view of the male connector in the diagram. Figure 6 for Figure 5 A schematic diagram of the shell structure in the middle. Figure 7 for Figure 6 A cross-sectional view of the shell inside. Figure 8 for Figure 1 The diagram shows a cross-sectional view of the power connector.

[0090] like Figure 4 As shown, the male connector 100 includes a male current-carrying terminal 120 and a housing 110. Wherein, combined with Figure 5 and Figure 6It is understood that the housing 110 includes a receiving cavity 113, a first opening 114, and a second opening 115, the first opening 114 and the second opening 115 respectively connecting the interior and exterior of the receiving cavity 113. The male current-carrying terminal 120 is used for electrical connection with the power connector 400 (e.g., ...). Figure 2 As shown), at least a portion of the male current-passing terminal 120 is located inside the receiving cavity 113, for example... Figure 8 As shown, the male current-passing terminal 120 is located inside the receiving cavity 113. Of course, the male current-passing terminal 120 may also be partially located inside the receiving cavity 113 and partially located outside the receiving cavity 113. The first end of the male current-passing terminal 120 is close to the first opening 114 and is used to insert and electrically connect with the female current-passing terminal 220 of the female connector 200. The second end of the male current-passing terminal 120 is close to the second opening 115 and electrically connected to the power connector 400 through the second opening 115.

[0091] In this way, by plugging or unplugging the female current-passing terminal 220 and the male current-passing terminal 120, the power connector 300 can be switched between a connected state and a disconnected state. Electrical connection between the male current-passing terminal 120 and the female current-passing terminal 220 enables electrical connection between the male connector 100 and the female connector 200.

[0092] In addition, as described above, the power connector 400 can be a cable or a copper busbar. Therefore, the second end of the male current-passing terminal 120 can be electrically connected to the cable or copper busbar. The male current-passing terminal 120 can support flexible cable connection or hard copper busbar connection, thereby enabling the male connector 100 to support flexible cable connection or hard copper busbar connection. Consequently, the power connector 300 can support flexible cable connection or hard copper busbar connection, improving the flexibility of the power connector 300 and enabling its application in different scenarios.

[0093] For example, such as Figure 5 As shown, the housing 110 includes a protective cover 111 and a bottom shell 112. The bottom shell 112 has a first opening 114. The bottom shell 112 is fixedly connected to the protective cover 111 and forms a receiving cavity 113 and a second opening 115. The bottom shell 112 and the protective cover 111 can be fixedly connected by snap-fit, threaded connection, or other methods. Furthermore, both the protective cover 111 and the bottom shell 112 are made of non-conductive materials; for example, both the protective cover 111 and the bottom shell 112 are made of plastic.

[0094] like Figure 5 As shown, there are two male current-carrying terminals 120, which are insulated from each other to form a closed circuit. Correspondingly, in some embodiments, such as... Figure 6As shown, there are two receiving cavities 113, two first openings 114, and two second openings 115. In this case, two male current-passing terminals 120 correspond one-to-one with two receiving cavities 113, and each male current-passing terminal 120 is located inside the corresponding receiving cavity 113. Each receiving cavity 113 is provided with one first opening 114 and one second opening 115. Alternatively, in some embodiments, there may be one receiving cavity 113, and two first openings 114 and two second openings 115, with each male current-passing terminal 120 corresponding to one first opening 114 and one second opening 115. Alternatively, in some embodiments, there may be one receiving cavity 113, one first opening 114, and one second opening 115.

[0095] Figure 9 for Figure 8 A schematic diagram showing the connection between the male current-carrying terminal and the power connector.

[0096] In some embodiments, such as Figure 9 As shown, the male current-passing terminal 120 includes a first current-passing portion 122 and a second current-passing portion 123. The extending direction of the first current-passing portion 122 intersects but does not coincide with the extending direction of the second current-passing portion 123, for example... Figure 8 As shown, the extending direction of the first flow passage 122 is perpendicular to the extending direction of the second flow passage 123. In this case, the structure of the male current-passing terminal 120 is similar to an L-shape. One end of the first flow passage 122 is connected to one end of the second flow passage 123. The other end of the first flow passage 122 serves as the first end of the male current-passing terminal 120, and the other end of the second flow passage 123 serves as the second end of the male current-passing terminal 120. Therefore, referring to… Figure 8 The first current-passing part 122 is used to electrically connect with the female current-passing terminal 220, and the second current-passing part 123 is used to electrically connect with the power connector 400, so as to realize the electrical connection between the male current-passing terminal 120 and the power connector 400 and the female current-passing terminal 220.

[0097] Figure 10 for Figure 9 A cross-sectional view of the male current-carrying terminal in the diagram.

[0098] The specific structure of the first current-passing section 122 is not limited here. It can be determined based on the scheme where the male current-passing terminal 120 and the female current-passing terminal 220 are plugged in and electrically connected, for example, in combination with... Figure 9 and Figure 10 It can be seen that the first flow passage 122 can be a hollow structure and the shape of the first flow passage 122 is cylindrical. Of course, the first flow passage 122 can also be other structures. For example, one end of the first flow passage 122 is provided with a blind hole and the shape of the first flow passage 122 can be prismatic.

[0099] To reduce the difficulty of connecting the second current-passing section 123 to the power connector 400 such as a cable or copper busbar, in some embodiments, such as Figure 9 As shown, the second current-passing part 123 has a contact plane 124, which is used to contact and connect with structures such as cables or copper busbars. Of course, in addition to making electrical contact with cables or copper busbars through the contact plane 124, in some embodiments, the second current-passing part 123 may also include a contact groove for inserting cables or copper busbars to achieve electrical contact between the second current-passing part 123 and the cables or copper busbars.

[0100] The specific structure of the second flow passage 123 is not limited here. In some embodiments, such as Figure 9 As shown, the second flow passage 123 can be a flat plate structure. In other embodiments, the second flow passage 123 can be a semi-cylindrical, semi-elliptical cylinder, or other structures.

[0101] like Figure 9 As shown, the second end of the male current-carrying terminal 120 can be directly connected to the power connector 400. However, the power connector 400 can also be indirectly electrically connected to the second end of the male current-carrying terminal 120.

[0102] Figure 11 This is a schematic diagram of another male connector provided in an embodiment of this application. Figure 12 for Figure 11 The diagram shows a cross-sectional view of the male connector.

[0103] In some embodiments, for example Figure 12 As shown, the male connector 100 also includes a copper busbar connector 140. One end of the copper busbar connector 140 extends into the interior of the receiving cavity 113 through the second opening 115 and is electrically connected to the second end of the male current-carrying terminal 120. The other end of the copper busbar connector 140 is located outside the receiving cavity 113 and is electrically connected to the power connector 400 (not shown in Figure 12). In this way, the male current-carrying terminal 120 is electrically connected to the power connector 400 through the copper busbar connector 140, so that the male connector 100 and the power connector 400 do not need to be assembled into a whole beforehand. The appropriate type of power connector 400 (such as cable or copper busbar) can be selected as needed, further improving the flexibility of the male connector 100.

[0104] Since the power connection can be a cable or a copper busbar, the male current-carrying terminal 120 can be directly connected to the copper busbar, or indirectly connected to the copper busbar through the copper busbar connector 140. Similarly, the male current-carrying terminal 120 can be directly connected to a cable, or indirectly connected to a cable through the copper busbar connector 140.

[0105] For example, such as Figure 11As shown, the copper busbar connector 140 is provided with a fastening through hole (such as...). Figure 16 As shown in Figure J), ​​the fastening through hole is used for the insertion of a fastening screw passing through the power connector 400, thereby achieving an electrical connection between the copper busbar connector 140 and the power connector 400. In this way, the connection difficulty between the power connector 400 and the copper busbar connector 140 can be reduced, and a detachable connection between the power connector 400 and the copper busbar connector 140 can be achieved.

[0106] Figure 13 for Figure 4 A cross-sectional view of the female connector in the diagram.

[0107] like Figure 4 As shown, the female connector 200 includes a housing 210 and a female current-passing terminal 220. Wherein, as... Figure 13 As shown, a portion of the female current-passing terminal 220 is embedded inside the housing 210, while the other portion of the female current-passing terminal 220 is located outside the housing 210 and is used for electrical connection with the circuit board 500. The first end of the female current-passing terminal 220 is used for electrical connection with the circuit board 500 (e.g., ...). Figure 4 As shown), the second end of the female current-passing terminal 220 is used to plug into and electrically connect with the male current-passing terminal 120 (as shown). Figure 8 (As shown).

[0108] like Figure 4 As shown, there are two female current-carrying terminals 220, which are insulated from each other to form a closed circuit. The two female current-carrying terminals 220 correspond one-to-one with the two male current-carrying terminals 120, and each female current-carrying terminal 220 is plugged into and electrically connected to the corresponding male current-carrying terminal 120.

[0109] like Figure 2 As shown, when the male connector 100 is connected to the female connector 200, a portion of the female current-passing terminal 220 extends into the interior of the receiving cavity 113 through the first opening 114 and is plugged into and electrically connected to the first end of the male current-passing terminal 120. It should be noted that when the male connector 100 is connected to the female connector 200, the female current-passing terminal 220 can also be located outside the receiving cavity 113.

[0110] In this embodiment of the application, in order to enable the male current-passing terminal 120 and the female current-passing terminal 220 to be inserted, one of the first end of the male current-passing terminal 120 and the second end of the female current-passing terminal 220 has a socket 121 for insertion with the other, for example... Figure 10 As shown, the first end of the male current-passing terminal 120 has a socket 121 for insertion of the second end of the female current-passing terminal 220. However, the socket 121 may also be provided on the second end of the female current-passing terminal 220 (not shown in the figure). For example, as... Figure 10As shown, the socket 121 can be a through hole structure that passes through the male current-carrying terminal 120. Of course, the socket 121 can also be a blind hole structure.

[0111] When the male connector 100 is connected to the female connector 200, such as Figure 8 As shown, a portion of the female current-passing terminal 220 extends into the receiving cavity 113 and is inserted into the socket 121, thereby enabling the male current-passing terminal 120 to be plugged into and electrically connected to the female current-passing terminal 220.

[0112] In this embodiment, when the circuit board assembly is applied to different scenarios, the male connector 100 supporting either flexible cable connection or rigid copper busbar connection can be selected according to the scenario conditions (e.g., space, current carrying capacity, etc.). For example, when the circuit board assembly is applied to a space-constrained scenario, the male connector 100 with rigid copper busbar connection is selected and plugged into and electrically connected to the female connector 200 to form a power connector 300 supporting rigid copper busbar connection. Alternatively, when the circuit board assembly is applied to a space-constrained scenario, the male connector 100 with flexible cable connection is selected and plugged into and electrically connected to the female connector to form a power connector 300 supporting flexible cable connection.

[0113] Therefore, it can be seen that the power connector 300 supports both flexible cable connections and rigid copper busbar connections. The power connector 300 does not limit the application of the circuit board assembly to different scenarios. When the circuit board assembly is applied to different scenarios, there is no need to redesign the power connector 300 and the circuit board assembly, which improves the versatility and flexibility of the circuit board assembly and the power connector 300, reduces the cost of functional modules, and reduces the design cost of electronic devices.

[0114] When the male current-carrying terminal 120 and the female current-carrying terminal 220 are plugged in, in order to make them electrically connected, in some possible implementations, such as Figure 5 As shown, the male connector 100 also includes a resilient conductive element 130. Wherein, as... Figure 8 As shown, the elastic conductive element 130 is located inside the socket 121 and is electrically connected to the male current-carrying terminal 120. When the first end of the male current-carrying terminal 120 is inserted into the female current-carrying terminal 220, the elastic conductive element 130 abuts against the female current-carrying terminal 220 and is electrically connected to the female current-carrying terminal 220. Because the elastic conductive element 130 is elastic, it undergoes elastic deformation after abutting against the female current-carrying terminal 220, creating a force between them to ensure tight contact and a stable electrical connection.

[0115] It should be noted that, in addition to the male connector 100 including the elastic conductive element 130, in some embodiments, the female connector 200 may also include the elastic conductive element 130. The elastic conductive element 130 is fixedly connected to the female current-passing terminal 220 and electrically connected to the female current-passing terminal 220. When the male current-passing terminal 120 is inserted into the female current-passing terminal 220, at least a portion of the elastic conductive element 130 is located in the socket 121 and abuts against the male current-passing terminal 120, thereby achieving the purpose of electrically connecting the male current-passing terminal 120 and the female current-passing terminal 220.

[0116] In some embodiments, such as Figure 8 As shown, when the male current-carrying terminal 120 and the female current-carrying terminal 220 are inserted, the elastic conductive element 130 is located between the side wall of the socket 121 and the side wall of the female current-carrying terminal 220 along the radial direction of the socket 121. Alternatively, in some embodiments, when the male current-carrying terminal 120 and the female current-carrying terminal 220 are inserted, the elastic conductive element 130 is located between the end face of the female current-carrying terminal 220 and the inner wall of the socket 121 along the axial direction of the socket 121. Alternatively, in some embodiments, when the male current-carrying terminal 120 and the female current-carrying terminal 220 are inserted, a portion of the elastic conductive element 130 is located between the side wall of the socket 121 and the side wall of the female current-carrying terminal 220 along the radial direction of the socket 121, and another portion of the elastic conductive element 130 is located between the end face of the female current-carrying terminal 220 and the inner wall of the socket 121 along the axial direction of the socket 121.

[0117] For example, such as Figure 5 As shown, the elastic conductive element 130 is a crown spring, which is located inside the socket 121 (e.g. Figure 12 As shown), when the first end of the male current-passing terminal 120 is inserted into the second end of the female current-passing terminal 220, the crown spring is sleeved on the female current-passing terminal 220 and abuts against the female current-passing terminal 220 radially along the insertion hole 121 (as shown). Figure 8 (As shown). Because crown springs can store a large amount of energy in a small space, they contribute to compact designs. While providing the same spring force, the outer diameter of the crown spring can be made smaller, which helps save space and ensures stable electrical contact with the female current-carrying terminal 220.

[0118] In some embodiments, the inner wall of the insertion hole 121 is further provided with an annular groove, and part of the crown spring is located inside the annular groove. The two opposite ends of the crown spring are respectively connected to the inner wall of the annular groove along the axial direction of the insertion hole 121. This can prevent the crown spring from moving linearly relative to the male end current terminal 120 along the axial direction of the insertion hole 121 during the insertion process of the male end current terminal 120 and the female end current terminal 220.

[0119] It should be noted that the elastic conductive element 130 can be any structure other than a crown spring. For example, the elastic conductive element 130 may include multiple elastic conductors arranged at intervals along the circumference of the insertion hole 121. When the male current-passing terminal 120 is inserted into the female current-passing terminal 220, the multiple elastic conductors are arranged around the female current-passing terminal 220 and respectively abut against the female current-passing terminal 220.

[0120] In some possible implementations, such as Figure 13 As shown, the female current-passing terminal 220 includes a pin portion 221, an insert portion 222, and a connecting portion 223 connected in sequence. The insert portion 222 is embedded inside the housing 210, the connecting portion 223 is located outside the housing 210 and is electrically connected to the circuit board 500, and the pin portion 221 is located outside the housing 210 and is used to insert and electrically connect with the male current-passing terminal 120. Thus, when the male current-passing terminal 120 is inserted into the female current-passing terminal 220, the pin portion 221 extends into the receiving cavity 113 through the first opening 114 and is inserted into the socket 121, and the elastic conductive member 130 is sleeved on the pin portion 221 and abuts against the pin portion 221. The pin portion 221 is electrically connected to the male current-passing terminal 120 through the elastic conductive member 130.

[0121] When the power connector 400 is a cable, the cable is directly connected to the male current-carrying terminal 120. Bending the cable relative to the male current-carrying terminal 120 generates a rotational force, causing the male current-carrying terminal 120 to rotate and collide with the housing 110. However, since the housing 110 is typically made of plastic, the collision between the male current-carrying terminal 120 and the housing 110 will cause damage to the plastic walls around the male current-carrying terminal 120 (such as...). Figure 16 As shown in Figure S, problems such as breakage, cracking, and deformation may occur. In addition, when the power connector 400 is a copper busbar, tightening screws on the copper busbar or the copper busbar connector 140 will also generate a rotational force that causes the male current-carrying terminal 120 to rotate. The male current-carrying terminal 120 will also collide with the housing 110, resulting in problems such as breakage, cracking, and deformation of the plastic wall around the male current-carrying terminal 120.

[0122] Figure 14 for Figure 2 The diagram shows a cross-sectional view of the connecting component. Figure 15 for Figure 1 A schematic diagram of the internal structure of the male connector after removing the protective cover from the housing. Figure 16 This is a schematic diagram of another anti-rotation structure provided in an embodiment of this application.

[0123] Regarding the issue of rotating the male current-carrying terminal 120, some possible implementations include, for example... Figure 14As shown, the male connector 100 also includes an anti-rotation structure 160, which is disposed between the male current-carrying terminal 120 and the housing 110. The anti-rotation structure 160 is used to prevent the male current-carrying terminal 120 from rotating. Thus, when a rotational force is applied to the male current-carrying terminal 120, the anti-rotation structure 160 will prevent the male current-carrying terminal 120 from rotating, preventing it from colliding with its surrounding plastic walls and avoiding damage, cracking, or deformation of the housing 110. Furthermore, the anti-rotation structure 160 can further ensure that the male current-carrying terminal 120 can be connected to a cable or copper busbar, allowing the male current-carrying terminal 120 to support either a flexible cable connection or a rigid copper busbar connection.

[0124] For example, such as Figure 14 As shown, the anti-rotation structure 160 includes a mating part 162 and a limiting part 161. Wherein, as... Figure 15 As shown, a limiting part 161 is disposed on the male current-passing terminal 120, and a mating part 162 is disposed on the housing 110. Along the circumference of the first opening 114 (or along the rotation direction of the male current-passing terminal 120), the limiting part 161 abuts against the mating part 162 to prevent the male current-passing terminal 120 from rotating. Thus, when a rotational force is applied to the male current-passing terminal 120, the limiting part 161 abuts against the mating part 162, preventing the male current-passing terminal 120 from rotating, avoiding collision between the male current-passing terminal 120 and the housing 110, and preventing problems such as damage, cracking, and deformation of the housing 110.

[0125] In one implementation, such as Figure 14 As shown, there is one mating part 162 and one limiting part 161. In another embodiment, there are multiple mating parts 162 and multiple limiting parts 161, with each mating part 162 abutting against the corresponding limiting part 161. For example... Figure 16 As shown, there are two limiting parts 161 and two mating parts 162. The two limiting parts 161 are located on opposite sides of the male current-passing terminal 120.

[0126] In one embodiment, one of the limiting part 161 and the mating part 162 is a boss, and the other is a groove for the boss to be inserted into, for example... Figure 15 As shown, the limiting part 161 is a boss, and the mating part 162 is a groove, or, as Figure 16As shown, both limiting portions 161 are grooves, and both mating portions 162 are bosses. Therefore, the number of mating portions 162 and limiting portions 161 can be one or more, with each limiting portion 161 having the same structure and each mating portion 162 having the same structure. This reduces the manufacturing difficulty of the male terminal 120 and the housing 110, and improves the manufacturing efficiency of the male connector 100. Furthermore, the interaction between the grooves and bosses reduces the assembly difficulty between the housing 110 and the male terminal 120, and prevents the male terminal 120 from rotating.

[0127] In another embodiment, there are at least two limiting portions 161 and at least two mating portions 162, and the limiting portions 161 and at least two mating portions 162 correspond one-to-one. A portion of all limiting portions 161 is a groove and another portion is a boss, and a portion of all mating portions 162 is a groove and another portion is a boss. That is, a portion of all limiting portions 161 is a first limiting portion and another portion is a second limiting portion, and a portion of all mating portions 162 is a first mating portion and another portion is a second mating portion. The first limiting portion is a groove and the second limiting portion is a boss. The first mating portion is a boss for inserting into the first limiting portion, and the second mating portion is a groove for inserting into the second limiting portion.

[0128] It should be noted that, in addition to being constructed using grooves and bosses, the anti-rotation structure 160 can also be other structures. For example, the anti-rotation structure 160 can also include two abutting members, which are located on opposite sides of the male current-passing terminal 120. The abutting members are located between the male current-passing terminal 120 and the side wall of the receiving cavity 113, and abut against the housing 110 and the male current-passing terminal 120 respectively. In this way, when a rotational force is applied to the male current-passing terminal 120, the male current-passing terminal 120 cannot rotate because the abutting members abut against the housing 110 and the male current-passing terminal 120 respectively, thus preventing the housing 110 from colliding with the male current-passing terminal 120.

[0129] To prevent the male current-carrying terminal 120 from moving up and down along the axial direction of the first opening 114, in some possible implementations, such as Figure 15 As shown, the male connector 100 also includes a limiting member 150, at least a portion of which is located inside the receiving cavity 113 and fixedly connected to the housing 110. Along the axial direction of the first opening 114, the opposite ends of the male current-passing terminal 120 abut against the limiting member 150 and the inner wall of the receiving cavity 113, respectively.

[0130] Thus, as Figure 2As shown, since the opposite ends of the male current-passing terminal 120 abut against the limiting member 150 and the inner wall of the receiving cavity 113 respectively, the male current-passing terminal 120 is clamped, preventing it from moving up and down along the axial direction of the first opening 114. This ensures that the relative positional relationship between the male current-passing terminal 120 and the housing 110 remains unchanged. When the male connector 100 is connected to the female connector 200, the male current-passing terminal 120 can be stably plugged into and electrically connected to the female current-passing terminal 220. In addition, when the cable is bent up and down or the copper busbar moves up and down, the male current-passing terminal 120 will not move up and down along the axial direction of the first opening 114, ensuring that the male current-passing terminal 120 supports both flexible cable connections and rigid copper busbar connections.

[0131] It should be noted that when a portion of the male end current-passing terminal 120 extends out of the first opening 114, that is, when a portion of the first current-passing part 122 extends out of the first opening 114, the first current-passing part 122 may include a first part and a second part. The first part is located inside the receiving cavity 113, and the second part is located outside the receiving cavity 113. The outer diameters of the first part and the second part are different and form a stepped surface. This stepped surface is used to abut against the inner wall of the receiving cavity 113 near the first opening 114.

[0132] The male connector 100 also includes an insertion through-hole 118 extending through the housing 110 (e.g. Figure 6 As shown), Figure 15 As shown, a portion of the limiting member 150 is located inside the receiving cavity 113, and another portion is located inside the insertion through hole 118. Of course, in some embodiments, the limiting member 150 may also be located inside the receiving cavity 113.

[0133] The specific structure of the limiting member 150 is not limited here. For example, the limiting member 150 may include a first strip portion and a second strip portion, which are stacked on top of each other. The length of the first strip portion is greater than the length of the second strip portion, and the width of the first strip portion is greater than the width of the second strip portion. The second strip portion is used to make an interference fit with the inner wall of the insertion through hole 118, so as to realize the fixed connection between the limiting member 150 and the housing 110 and reduce the number of parts of the male connector 100, thereby improving the assembly efficiency of the male connector 100.

[0134] Figure 17 This is a cross-sectional schematic diagram of another male connector provided in an embodiment of this application.

[0135] like Figure 8 As shown, the number of limiting members 150 can also be one. Of course, the number of limiting members 150 can also be multiple. For example, in some embodiments, such as... Figure 17As shown, there are two limiting members 150, namely the first limiting member 150a and the second limiting member 150b. Along the axial direction of the first opening 114, the opposite ends of the first flow passage 122 abut against the inner wall of the receiving cavity 113 and the first limiting member 150a, respectively. The opposite ends of the second flow passage 123 abut against the inner wall of the receiving cavity 113 and the second limiting member 150b, respectively. In this way, vertical movement of the male flow terminal 120 is prevented, and the overall limiting effect of the male flow terminal 120 is improved.

[0136] In some possible implementations, one of the housings 210 and 110 has a slot 211 for partial insertion of the other. Thus, when the male connector 100 is inserted into the female connector 200, a portion of one of the housings 210 and 110 is inserted into the slot 211 of the other, enabling the housings 210 and 110 to be inserted. This helps improve the reliability of the connection between the male connector 100 and the female connector 200, and also helps one of the male current-passing terminals 120 and 220 to be inserted into the socket 121 of the other, increasing the insertion speed of the female connector 200 and the male connector 100.

[0137] In some embodiments, such as Figure 4 As shown, the housing 210 has a slot 211. At this time, a portion of the female current-passing terminal 220 is located inside the slot 211 and is used for insertion and electrical connection with the male current-passing terminal 120. When the male connector 100 is inserted into the female connector 200, a portion of the housing 110 is inserted into the slot 211 (e.g., ...). Figure 8 (As shown). Thus, by placing the slot 211 on the housing 210, it helps to reduce the difficulty of inserting the housing 110 and the housing 210 together, and reduces the size of the male connector 100.

[0138] like Figure 4 As shown, there are two female current-passing terminals 220 and one slot 211. However, in some embodiments, there may also be two slots 211, with each slot 211 corresponding to one female current-passing terminal 220, for example... Figure 18 As shown. Among them, Figure 18 This is a cross-sectional schematic diagram showing the mating of another female connector with a circuit board, as provided in an embodiment of this application.

[0139] For example, such as Figure 13 As shown, the housing 210 includes a body portion 212 and an extension portion 213. The body portion 212 and the extension portion 213 are an integral structure. The body portion 212 has a slot 211. The extension portion 213 is located outside the slot 211. The extension portion 213 is used to insert into the fixing hole on the circuit board 500 to realize the fixed connection between the housing 210 and the circuit board 500.

[0140] In some embodiments, such as Figure 6 As shown, the housing 110 includes a main body 116 and an insertion portion 117. The insertion portion 117 has a first opening 114 for insertion into a slot 211 of the housing 210, and the main body 116 has a second opening 115. Figure 8 As shown, when the male connector 100 is connected to the female connector 200, the insertion part 117 is inserted into the inside of the slot 211 to realize the insertion of the housing 110 and the outer shell 210.

[0141] It should be noted that, in addition to being provided in the housing 210, in some embodiments the housing 110 may also have a slot 211. In this case, the first opening 114 connects the receiving cavity 113 and the interior of the slot 211. When the male connector 100 is connected to the female connector 200, at least a portion of the housing 210 is used to insert into the interior of the slot 211.

[0142] like Figure 5 As shown, the housing 110 is composed of a bottom shell 112 and a protective cover 111. The bottom shell 112 includes a first shell part and a second shell part with an integral structure. The first shell part is fixedly connected to the protective cover 111 and forms the main body part 116. The second shell part forms the insertion part 117.

[0143] In some embodiments, such as Figure 6 As shown, there is one insertion part 117, and in this case, there are two first openings 114. Of course, there can also be one first opening 114. Alternatively, in some embodiments, there can be two insertion parts 117, which are arranged side by side and spaced apart. Each insertion part 117 has a first opening 114, and each insertion part 117 corresponds to a slot 211 and is used to insert into the corresponding slot 211. Thus, the exposed female current-passing terminal 220 in each slot 211 is plugged into and electrically connected to the male current-passing terminal 120 through the corresponding first opening 114.
