Description

[0001] This application claims the priority of the Chinese patent application filed with the China Patent Office on July 5, 2023, with application number 202310821110.3 and application name “A Connector and Power Supply Device”, the entire contents of which are incorporated by reference in this application. Technical Field

[0002] The present application relates to the technical field of electrical devices, and in particular to a connector and a power supply device. Background Art

[0003] The power supply device is used to switch between direct current (DC) and alternating current (AC). The multiple power terminals of the power supply device can be connected to the load through connectors. By plugging and unplugging the connector, the electrical connection between the connector and the power terminal can be turned on or off, thereby turning on or off the power supply of the power supply device to the load.

[0004] When plugging and unplugging the connector while it is powered, arcing will occur between the connector and the power terminal, causing safety hazards. In the prior art, it is usually necessary to suspend the operation of the power supply device before plugging and unplugging the connector, which often results in the need to suspend the power supply of the power supply device to other power terminals for maintenance operations on one power terminal, thereby affecting the user experience. Alternatively, multiple switch modules need to be configured between the power circuit of the power supply device and multiple power terminals, and the conduction or disconnection of the electrical connection between the power circuit and the multiple power terminals is controlled by multiple switch modules respectively, which not only increases the production cost of the power supply device but also increases the operating complexity of the power supply device, thereby increasing the possibility of misoperation, thereby causing safety hazards. Summary of the invention

[0007] In this solution, when the driving rod moves along the first direction, it can drive the movable electrical connector to conduct or disconnect the electrical connection with the power terminal, that is, when the driving rod moves along the first direction, it can drive the movable electrical connector to conduct or disconnect the electrical connection between the connector and the power circuit of the power supply device. That is to say, when using the connector provided by this embodiment, moving the driving rod along the first direction can realize whether the connector is energized or not. Therefore, when it is necessary to plug and unplug the connector, the driving rod is moved to disconnect the electrical connection between the connector and the power circuit of the power supply device, that is, the plug and unplug of the connector with power can be avoided, and then the impact of the plug and unplug of the connector with power on the service life of the connector and the power terminal can be avoided. At the same time, it is also beneficial to avoid the occurrence of electric shock when the staff plugs and unplugs the connector. Compared with the prior art, when using the connector provided by this solution, when plugging and unplugging a connector, there is no need to suspend the power supply of the power supply device to other power terminals, the operation is simpler, the impact on the user's use is smaller, and the user experience is better. When using the connector provided by this solution, there is no need to configure multiple switch modules between the power circuit of the power supply device and multiple power terminals, which is beneficial to the cost control of the power supply device, the operation complexity of the power supply device and the possibility of misoperation by the staff.

[0091] Figure 1 A schematic diagram of the structure of a power supply device provided in an embodiment of the present application is shown in FIG. Figure 2 This is a partial structural diagram of a power supply device provided in an embodiment of the present application. Figure 1 and Figure 2As shown, a power supply device provided in an embodiment of the present application includes a power supply housing 10, a power circuit (not shown in the figure), a plurality of power terminals 20 and at least one connector 30. Specifically, the power supply housing 10 is used to accommodate the power circuit. For example, the power circuit is made on a circuit board (not shown in the figure), and the circuit board made with the power circuit is fixed in the power supply housing 10. Further, the plurality of power terminals 20 are electrically connected to the power circuit, and each power terminal 20 is fixed to the power supply housing 10 and exposed to the power supply housing 10 for plugging and unplugging of the connector 30.

The first direction A is parallel to the plug-in and unplug direction of the connector 30. It is worth noting that Figure 3 In the embodiment, the movable electrical connector 31 is in a position where the electrical connection between the power terminal 20 and the connector 30 can be conducted. In this solution, when the driving rod 33 moves along the first direction A, the movable electrical connector 31 can be driven by the transmission assembly 32 to conduct or disconnect the electrical connection with the power terminal 20, that is, when the driving rod 33 moves along the first direction A, the movable electrical connector 31 can be driven by the transmission assembly 32 to conduct or disconnect the electrical connection between the connector 30 and the power circuit of the power supply device. In other words, when the power supply device provided by this embodiment is used, the connector 30 can be energized or not by moving the driving rod 33 along the first direction A. Therefore, when the connector 30 needs to be plugged in or unplugged, the driving rod 33 is moved to disconnect the electrical connection between the connector 30 and the power circuit of the power supply device, that is, the plugging and unplugging of the connector 30 with power can be avoided, thereby avoiding the influence of the plugging and unplugging of the connector 30 with power on the service life of the connector 30 and the power terminal 20, and at the same time, it is also conducive to avoiding the occurrence of electric shock when the staff plugs and unplugs the connector 30. Compared with the prior art, when using the power supply device provided by the present application, plugging and unplugging a connector 30 does not require the power supply device to other power terminals 20 to be suspended, which makes the operation easier, has less impact on the user's use, and provides a better user experience. When using the power supply device provided by the present solution, there is no need to configure multiple switch modules between the power circuit of the power supply device and multiple power terminals 20, which is beneficial to controlling the cost of the power supply device, reducing the operation complexity of the power supply device, and at the same time, it is also beneficial to reducing the possibility of misoperation by the staff.

[0092] In addition, the moving direction of the driving rod 33 is parallel to the plugging and unplugging direction of the connector 30, which is more convenient for the staff to remember and operate.

[0093] In another implementation, the transmission assembly 32 may not be provided, but the driving rod 33 moves relative to the connector housing 34 along the first direction A and directly drives the movable electrical connector 31 to make the movable electrical connector 31 conduct or disconnect the electrical connection between the connector 30 and a power terminal 20.

[0094] It is worth noting that the movement of the driving rod 33 along the first direction A includes movement along the direction A1 of the connector 30 pulling out the power terminal 20 and movement along the direction A2 of the connector 30 inserting the power terminal 20. In a specific implementation, the driving rod 33 moves along the direction A1 of the connector 30 pulling out the power terminal 20, and the driving rod 33 drives the movable electrical connector 31 to disconnect the electrical connection between the connector 30 and the power terminal 20. The driving rod 33 moves along the direction A2 of the connector 30 inserting the power terminal 20, and the driving rod 33 drives the movable electrical connector 31 to conduct the electrical connection between the connector 30 and the power terminal 20. That is, when the electrical connection between the connector 30 and the power terminal 20 is disconnected, the movement direction of the driving rod 33 is parallel to the movement direction of the connector 30 when the connector 30 is pulled out of the power terminal 20, and when the electrical connection between the connector 30 and the power terminal 20 is conducted, the movement direction of the driving rod 33 is parallel to the movement direction of the connector 30 when the connector 30 is inserted into the power terminal 20, which is further conducive to the understanding and memory of the staff and is conducive to improving the work efficiency of the staff.

[0095] When the power supply device is specifically configured, the number of the power terminals 20 can be set according to actual needs, and is not limited in this embodiment. For example, the power terminals 20 can be one, two, or three.

Taking the direction perpendicular to both the first direction A and the second direction C as the third direction D, the two power connectors 21 in each power terminal 20 are arranged at intervals along the second direction C, which is conducive to reducing the size of the power supply device in the third direction D, and thus is conducive to the application of the power supply device in the scenario where the space in the third direction D is limited. Exemplarily, both power connectors 21 can be copper bars.

[0103] When the above connector 30 is specifically configured, the connector 30 also includes a load connection cable 36 ( Figure 8 The load connecting cable 36 is used for electrical connection between the load device and the connector 30. Figure 8 ,like Figure 8As shown, the first end face 341 of the connector housing 34 includes a cable mounting hole 3412 that penetrates the first end face 341 along the first direction A. The cable mounting hole 3412 is used to pass the load connection cable 36, and the cable mounting hole 3412 and the drive rod mounting hole 3411 are arranged at intervals along the second direction C, so as to avoid the movement of the drive rod 33 and the interference of the load connection cable 36, and also facilitate the operation of the staff. Of course, the positional relationship between the cable mounting hole 3412 and the drive rod mounting hole 3411 is not limited to this. In other embodiments, the positional relationship between the cable mounting hole 3412 and the drive rod mounting hole 3411 can also be designed according to actual needs.

[0104] In a technical solution, the driving rod 33 and the transmission assembly 32 are arranged at intervals along the second direction C.

[0105] Fig. 9 This is a cross-sectional view of a connector in a power supply device provided in an embodiment of the present application, wherein the movable electrical connector 31 is in a position capable of disconnecting the electrical connection between the power terminal and the connector.

The first wire connection portion 38 electrically connects the first wire 361 and the movable electrical connector 31, and the second wire connection portion 39 electrically connects the second wire 362 and the fixed electrical connector 37. The first wire connection portion 38 and the second wire connection portion 39 are arranged at intervals along the second direction C, that is, the arrangement direction of the first wire connection portion 38 and the second wire connection portion 39 is parallel to the arrangement direction of the movable electrical connector 31 and the fixed electrical connector 37, and the arrangement direction of the first wire connection portion 38 and the second wire connection portion 39 is parallel to the arrangement direction of the movable electrical connector 31 and the fixed electrical connector 37, which can make the structure of the connector 30 more compact, which is conducive to reducing the volume of the connector 30, thereby avoiding interference between adjacent connectors 30, or interference between the connector 30 and surrounding components.

Fig. 9The figure only shows the connection relationship between the first wire 361 and the first wire connecting portion 38 and the second wire 362 and the second wire connecting portion 39. For example, the outer sleeve of the load connection cable 36 is provided with a cable sealing ring 60, and the load connection cable 36 is fixed to the cable installation hole 3412 through a nut 70, and the cable sealing ring 60 is sealed with the cable installation hole 3412.

[0106] Fig.10 This is a cross-sectional view of a connector in a power supply device provided in an embodiment of the present application, wherein the movable electrical connector 31 is in a position capable of conducting electrical connection between the power terminal and the connector. Fig.10 A connector 30 in a power supply device provided in an embodiment of the present application is introduced. A unit consisting of a fixed electrical connector 37 and a movable electrical connector 31 is an electrical connection unit 400, and a unit consisting of a first wire connection portion 38 and a second wire connection portion 39 is a cable connection unit 500. In one implementation, the transmission assembly 32 is located between the electrical connection unit 400 and the cable connection unit 500 along the first direction A. Compared with the situation where the electrical connection unit 400, the cable connection unit 500 and the transmission assembly 32 are arranged in sequence along the first direction A, this solution is conducive to simplifying the structure of the transmission assembly 32. Of course, according to actual needs, the electrical connection unit 400, the cable connection unit 500 and the transmission assembly 32 can also be arranged in sequence along the first direction A. It is worth noting that. Fig.10 In the figure, the outer diameters of the load connection cable 36, the first wire 361 and the second wire 362 do not represent the actual sizes. Fig.10 The figure only shows the connection relationship between the first wire 361 and the first wire connecting portion 38 and the second wire 362 and the second wire connecting portion 39 .

[0107] In one implementation, the projection of the cable mounting hole 3412 along the first direction A covers the projection of the first wire connection portion 38 and the second wire connection portion 39, thereby facilitating the connection between the first wire 361 and the first wire connection portion 38 and the connection between the second wire 362 and the second wire connection portion 39, and is conducive to the compactness of the connector 30 structure.

[0108] Further, Fig.11 It is a cross-sectional view of a connector in a power supply device provided in an embodiment of the present application, wherein the movable electrical connector 31 is in a position capable of conducting an electrical connection between the power terminal 20 and the connector 30 .

The first locking portion and the second locking portion are used to work together to lock the position of the drive rod 33 when the movable electrical connector 31 is electrically connected to the power terminal 20. Exemplarily, one of the first locking portion and the second locking portion includes a card block 41, and the other includes a card slot 42 matching the card block 41. Obviously, when the drive rod 33 moves to a position along the direction A2 of inserting the connector 30 into the power terminal 20, the card block 41 is engaged with the card slot 42. When the drive rod 33 moves to a position along the direction A1 of pulling out the connector 30 from the power terminal 20, the card block 41 is separated from the card slot 42.

[0109] A pull portion 401 is fixed to one end of the elastic arm 40 away from the housing, and the pull portion 401 and the first locking portion are arranged on opposite sides of the elastic arm 40. The staff can separate the block 41 from the slot 42 by pulling the pull portion 401, making the separation operation of the block 41 and the slot 42 easier.

[0110] Fig.13 This is a schematic diagram of the structure of a connector in another power supply device provided in an embodiment of the present application. Fig.14 for Fig.13 A cross-sectional view of Fig.13 and Fig.14As shown, in another specific implementation, the connector includes a push-pull handle 302 and a pull ring 303, and the connector housing 34 includes an installation chamber 343 for installing the push-pull handle 302. The push-pull handle 302 is installed in the installation chamber 343 and is slidably connected to the installation chamber 343, and the push-pull handle 302 is also fixedly connected to the driving rod 33, and the pull ring 303 is rotatably connected to the push-pull handle 302. In this way, the driving rod 33 can be driven to move along the first direction A by the pull ring 303, and the operation is more convenient. Further, the outer surface of the installation chamber 343 is provided with a protrusion 344 for fixing the pull ring 303. When the driving rod 33 moves to a position where the movable electrical connector 31 can conduct electrical connection between the connector 30 and the power terminal 20, after the pull ring 303 rotates relative to the connector housing 34, the free end of the pull ring 303 can be sleeved on the protrusion 344 on the surface of the installation chamber 343, thereby fixing the position of the driving rod 33. Exemplarily, the driving rod 33 includes a connection hole for connecting with the push-pull handle 302, and the end of the push-pull handle 302 that is used to be away from the power terminal 20 is sleeved on the driving rod 33 and is provided with a nut mounting hole, a nut 345 is embedded in the above-mentioned nut mounting hole, and a screw 346 is connected to the above-mentioned nut 345 and extends into the connection hole of the driving rod 33, so as to realize the connection between the push-pull handle 302 and the driving rod 33. Specifically, the above-mentioned nut 345 is a metal nut, the push-pull handle 302 is made of plastic, and the nut 345 and the push-pull handle 302 are integrally formed by injection molding. The head of the screw 346 is sunken in the nut mounting hole, and a plastic plugging member 347 is fixed in the above-mentioned nut 345 mounting hole to block the screw 346 and prevent the screw 346 from falling off. Exemplarily, the plastic plugging member 347 and the push-pull handle 302 can be connected together by ultrasonic welding.

[0111] Fig.15 for Fig.13 Schematic diagram of the connection between the push-pull handle and the pull ring. Fig.13 and Fig.15In a specific implementation, the push-pull handle 302 includes a handle body 3021 in the shape of a rectangular parallelepiped, and the handle body 3021 is made of an elastic material, for example, the handle body 3021 is made of plastic. Further, the handle body 3021 includes an oblong hole 3022 extending along the first direction A, and the oblong hole 3022 penetrates the handle body 3021 along the second direction C. The handle body 3021 is provided with protrusions 3023 on both sides in the third direction D, and the two protrusions 3023 are arranged opposite to each other in the third direction D, and the two protrusions 3023 extend in a direction away from the other protrusion 3023. The mounting chamber 343 of the connector housing 34 is provided with two groups of limiting holes 348 corresponding to the above two protrusions 3023, and the number of the limiting holes 348 in each group of limiting holes 348 is two, and the two limiting holes 348 correspond to the two protrusions 3023 one by one. The handle body 3021 is made of an elastic material, and the handle body 3021 includes an oblong hole 3022 extending along the first direction A, so that the portion of the handle body 3021 where the protrusion 3023 is located can be deformed under the action of an external force, and the protrusion 3023 can be engaged with the corresponding limiting hole 348, and can also be separated from the corresponding limiting hole 348. It is worth noting that when the protrusion 3023 is separated from the corresponding limiting hole 348, a sudden change in force can be generated during pulling, so that the movable electrical connector can be quickly separated, thereby further reducing the possibility of arc generation. Specifically, the two groups of limiting holes 348 are arranged at intervals along the first direction A, and when the driving rod 33 is in a position that enables the movable electrical connector 31 to conduct electrical connection between the connector 30 and the power terminal 20, the two protrusions 3023 are respectively engaged with two limiting holes 348 in a group of limiting holes 348, thereby fixing the position of the driving rod 33. When the driving rod 33 is in a position where the movable electrical connector 31 disconnects the electrical connection between the connector 30 and the power terminal 20, the two protrusions 3023 are respectively engaged with two stop holes 348 in another group of stop holes 348 to fix the position of the driving rod 33. In other words, when the driving rod 33 is in a position where the movable electrical connector 31 can conduct the electrical connection between the connector 30 and the power terminal 20, the position of the driving rod 33 is double locked by pushing and pulling the handle 302 and the pull ring 303 as well as the protrusions 3023 and the corresponding stop holes 348, thereby preventing the electrical connection between the connector and the power terminal from being disconnected due to misoperation of the driving rod.

[0112] Exemplarily, an operation indicator mark may be provided on the outer surface of the installation compartment 343 to inform the operator of the relationship between the moving direction of the push-pull handle 302 and the electrical connection state between the connector 30 and the power terminal 20. Exemplarily, the operation indicator mark may include two arrows 349, which are arranged in sequence along the first direction A, and one of the arrows 349 points to the direction A1 in which the connector 30 is pulled out of the power terminal 20, and the word "OFF" or "Close" is marked near the arrow end of the arrow 349. The other arrow 349 points to the direction A2 in which the connector 30 is inserted into the power terminal 20, and the word "ON" or "Open" is marked near the arrow end of the arrow 349, so that the operator can operate as needed and reduce the possibility of operator error.

Fig.13 and Fig.16 The push-pull handle 302 includes a toggle portion 3024, which is located at one end of the handle body 3021 that is away from the power terminal 20.

The status display component includes a toggle bar 304 and a display mark, wherein the toggle bar 304 is a bent structure, and the toggle bar 304 is rotatably arranged on the connector housing 34.

The connector housing 34 includes a notch portion 3401 facing the first direction A. In the process of the toggle portion 3024 moving along the first direction A with the handle body 3021, the toggle bar 304 rotates relative to the connector housing 34 under the pushing action of the toggle portion 3024 to switch the display mark opposite to the notch portion 3401. Specifically, when the driving rod 33 is in a position that enables the movable electrical connector 31 to conduct the electrical connection between the connector and the power terminal, the electrical connection mark 305 is opposite to the notch portion 3401. When the driving rod is in a position that enables the movable electrical connector to disconnect the electrical connection between the connector and the power terminal, the disconnection mark 306 is opposite to the notch portion 3401.

[0115] In another implementation, Fig.16As shown, the display mark includes two electrical connection marks 305 and two disconnection marks 306, the electrical connection marks 305 and the disconnection marks 306 are alternately arranged, and one of the electrical connection marks 305 is connected to the toggle bar 304, and the two electrical connection marks 305 and the two disconnection marks 306 together form an arc structure. The connector housing 34 includes a notch portion 3401 facing the first direction A and a notch portion 3401 facing the third direction D. In the process of the toggle portion 3024 moving along the first direction A with the handle body 3021, the toggle bar 304 rotates relative to the connector housing under the pushing action of the toggle portion 3024 to switch the display mark opposite to the notch portion 3401. Specifically, when the driving rod is in a position that enables the movable electrical connector to conduct the electrical connection between the connector and the power terminal, the two electrical connection marks 305 are respectively opposite to a notch portion 3401. When the driving rod is in a position that enables the movable electrical connector to disconnect the electrical connection between the connector and the power terminal, the two disconnection marks 306 are respectively opposite to a notch portion 3401. Obviously, the connector housing has a space for the display mark to move. In the above scheme, the operator can determine the electrical connection state between the connector and the power terminal by the display mark of the notch portion 3401. Exemplarily, the display mark can be a color mark, a symbol mark or a letter mark, for example, the electrical connection mark 305 is a red mark, and the disconnection mark 306 is a green mark.

[0116] The transmission process of the connector 30 in the power supply device provided in an embodiment of the present application is briefly described below. In one implementation, the drive rod 33 moves along the first direction A, and the drive rod 33 drives the movable electrical connector 31 to swing relative to the connector housing 34 and drives the movable electrical connector 31 to connect or disconnect the electrical connection between the connector 30 and the power terminal 20.

[0117] For details, please refer to Figure 8 , the connector 30 further includes an intermediate electrical connector 44, which is fixed in the connector housing 34, and along the first direction A, the movable electrical connector 31 is located between the intermediate electrical connector 44 and the first wire connecting portion 38. When the driving rod 33 moves along the direction A1 in which the connector 30 is pulled out of the power terminal 20, the driving rod 33 drives the movable electrical connector 31 to separate from the intermediate electrical connector 44, thereby enabling the electrical connection between the movable electrical connector 31 and the power terminal 20 to be disconnected. When the driving rod 33 moves along the direction A2 in which the connector 30 is inserted into the power terminal 20, the driving rod 33 drives the movable electrical connector 31 to be electrically connected to the intermediate electrical connector 44, thereby enabling the electrical connection between the movable electrical connector 31 and the power terminal 20 to be conducted. Exemplarily, the intermediate electrical connector 44 is an elastic conductive clip.

[0118] Furthermore, please combine Figure 8 and Fig.17,in, Fig.17 This is a partial structural diagram of a connector in a power supply device provided in an embodiment of the present application.

In a specific implementation, the driving arm 321 and the transmission arm 322 are an integrally formed structure. The transmission assembly 32 also includes a fixed arm 329 fixed in the connector housing, and the movable electrical connector 31, the driving arm 321 and the transmission arm 322 are all rotatably disposed on the fixed arm 329, and are rotatably disposed on the connector housing 34 through the fixed arm 329.

[0119] Combine the following Figure 8 The transmission process of the above connector is described. In this scheme, when the driving rod 33 moves along the direction A1 of the connector 30 pulling out the power terminal 20, the driving arm 321 and the transmission arm 322 rotate clockwise around the first rotation axis 100, the transmission arm 322 pulls the connecting arm 323, and the connecting arm 323 drives the movable electrical connector 31 to rotate clockwise around the third rotation axis 300, thereby realizing the separation of the movable electrical connector 31 and the intermediate electrical connector 44, so that the direct electrical connection between the movable electrical connector 31 and the intermediate electrical connector 44 is disconnected. When the driving rod 33 moves along the direction A2 of the connector 30 inserting the power terminal 20, the driving arm 321 and the transmission arm 322 rotate counterclockwise around the first rotation axis 100, the transmission arm 322 pushes the connecting arm 323, and the connecting arm 323 drives the movable electrical connector 31 to rotate counterclockwise around the third rotation axis 300, thereby realizing the electrical connection between the movable electrical connector 31 and the intermediate electrical connector 44.

[0120] In one implementation, the connector 30 further includes a toggle assembly, a buffer assembly, a reset assembly, and a retaining assembly housed in the connector housing 34. The toggle assembly is rotatably connected to the connector housing 34 and is used to toggle the drive rod 33 so that the connecting arm 323 and the transmission arm 322 can be separated from the transmission dead point position under the action of the drive rod 33. For example, Fig.17 As shown, as an alternative way for the push-pull handle 302 to drive the driving rod 33, the driving rod 33 includes a toggle slot 333, and the toggle assembly includes a toggle block 327. The toggle block 327 is used to rotate under the action of external force and act on the toggle slot 333, and drive the driving rod 33 to move in the direction of pulling out the power terminal 20 from the connector 30 through the toggle slot 333.

[0121] The buffer assembly is in contact with the movable electrical connector 31, and is used to apply a first force to the movable electrical connector 31. The first force makes the movable electrical connector 31 always have a tendency to swing in the direction of disengaging from the intermediate electrical connector 44, so as to avoid hard contact between the movable electrical connector 31 and the intermediate electrical connector 44, and prolong the service life of the movable electrical connector 31 and the intermediate electrical connector 44. Exemplarily, in one implementation, the buffer assembly may include a first spring (not shown in the figure), the first spring is located between the intermediate electrical connector 44 and the movable electrical connector 31 along the first direction A, and the first spring is always in a compressed state. In another implementation, the buffer assembly includes a first torsion spring 45, and a force-bearing portion 311 extending along a third direction D is fixed to one side of the movable electrical connector 31 toward the first wire connecting portion 38, and the force-bearing portion and the rotating shaft of the movable electrical connector 31, that is, the third rotating shaft 300 mentioned above, are located on the same side of the movable electrical connector 31, and there is a gap between the force-bearing portion and the movable electrical connector 31. The first torsion spring 45 is sleeved on the third rotating shaft 300, and the two force-applying ends of the first torsion spring 45 are respectively arranged on both sides of the rotation of the third rotating shaft 300. One force-applying end of the first torsion spring 45 is located in the gap between the force-bearing part and the movable electrical connector 31, and the other force-applying end of the first torsion spring 45 is against the connector housing 34. The two force-applying ends of the first torsion spring 45 always have a tendency to approach each other.

[0122] The reset assembly is in contact with the driving arm 321, and is used to make the driving arm 321 drive the driving rod 33 to move along the direction A1 of the connector 30 to pull out the power terminal 20. Exemplarily, in one implementation, the reset assembly may include a second spring (not shown in the figure), and along the direction A1 of the connector 30 to pull out the power terminal 20, the driving arm 321 is located between the second spring and the first wire connecting portion 38, and the second spring is always in a compressed state. Obviously, the second spring is compressed between the connector housing 34 and the driving arm 321. In another implementation, the reset assembly includes a second torsion spring 46, and the second torsion spring 46 is sleeved on the rotating shaft of the driving arm 321 and the transmission arm 322, that is, the above-mentioned first rotating shaft 100, and the two force-applying ends of the second torsion spring 46 are respectively arranged on both sides of the first rotating shaft 100, one force-applying end of the second torsion spring 46 acts on the driving arm 321, and the other force-applying end of the second torsion spring 46 is against the connector housing 34, and the two force-applying ends of the second torsion spring 46 always have a tendency to deviate from each other.

[0123] The retaining assembly is in contact with the movable electrical connector 31, and is used to apply a force to the movable electrical connector 31 toward the intermediate electrical connector 44. Exemplarily, in one implementation, the retaining assembly may include a third spring (not shown in the figure), the movable electrical connector 31 is located between the third spring and the intermediate electrical connector 44 along the first direction A, and the third spring is always compressed between the connector housing 34 and the intermediate electrical connector 44. In another implementation, the retaining assembly includes a third torsion spring 47, the third torsion spring 47 is sleeved on the rotating shaft between the movable electrical connector 31 and the transmission arm 322, that is, the above-mentioned second rotating shaft 200, the two force-applying ends of the third torsion spring 47 are respectively arranged on both sides of the rotation of the second rotating shaft 200, and one force-applying end of the third torsion spring 47 is in contact with the movable electrical connector 31, and the other force-applying end of the third torsion spring 47 is in contact with the transmission arm 322, and the two force-applying ends of the third torsion spring 47 always have a tendency to deviate from each other.

[0124] In another implementation, the driving rod 33 moves along the first direction A, and the driving rod 33 drives the movable electrical connector 31 to move in the same direction as the driving rod 33 and drives the movable electrical connector 31 to conduct or disconnect the electrical connection between the connector 30 and the power terminal 20. Specifically, the transmission assembly 32 includes a transmission seat 328, the transmission seat 328 is fixed to the first section 331 of the driving rod 33, and the movable electrical connector 31 is fixed to the transmission seat 328. When the driving rod 33 moves along the direction A1 of the connector 30 pulling out the power terminal 20, the driving rod 33 drives the movable electrical connector 31 to separate from the power terminal 20. The driving rod 33 moves along the direction A2 of the connector 30 inserting the power terminal 20, and the driving rod 33 drives the movable electrical connector 31 to be electrically connected to the power terminal 20. Exemplarily, the transmission seat 328 and the driving rod 33 can be an integrally formed structure.

[0125] Please continue to refer to Fig.14 In a specific implementation, the connector housing includes a first housing 3402 and a second housing 3403 fixed in the first housing 3402, the second housing 3403 accommodates a movable electrical connector, a transmission assembly, a first wire connection portion and a second wire connection portion, and partially accommodates a drive rod, and a drive rod mounting hole and a cable mounting hole are arranged in the first housing 3402. Fig.18 This is a schematic diagram of the structure of the second housing 3403 and the driving rod in a power supply device provided in an embodiment of the present application. Fig.18 As shown, the second housing 3403 includes a first portion 3404 and a second portion 3405 arranged relatively along a third direction, and the first portion 3404 and the second portion 3405 are snap-fitted to form the second housing 3403. Exemplarily, in a specific implementation, the first portion 3404 and the second portion 3405 have the same size in the third direction to facilitate the installation of internal components of the second housing 3403.

[0126] Exemplarily, the movable electrical connector includes a first connection pin 3101 for connecting to the transmission seat 328 and a second connection pin 3102 for electrically connecting to the first wire connection portion. When the connection between the first connection pin 3101 and the transmission seat 328 is specifically implemented, in a specific implementation, the transmission seat 328 is a plastic part, and the first connection pin 3101 and the transmission seat 328 are integrally formed by injection molding. Fig.19 This is a schematic diagram of a partial structure of a connector in a power supply device provided in an embodiment of the present application. Fig.19 As shown, in another implementation, the transmission seat includes a snap-in groove 3281 , and the first connecting foot 3101 is snap-into the snap-in groove 3281 .

[0127] Figure 20-21 They are schematic diagrams of the structure of a connector in a power supply device provided in an embodiment of the present application after being cut open. Fig. 20 As shown, when the second connection pin 3102 is specifically connected to the second wire connection portion, in one implementation, the second connection pin 3102 is connected to the second wire connection portion by welding through a conductive soft wire 600. The soft wire 600 may be a soft braided wire. Fig.21 As shown, in another implementation, the second wire connection portion includes a conductive elastic clip 391, the second connection pin 3102 is a conductive sheet, and the second wire connection portion and the second connection pin 3102 are electrically connected through the elastic clip 391 and the conductive sheet. Fig. 22 A schematic diagram of the structure of a connector in a power supply device provided in an embodiment of the present application after being cut open. Fig.23 for Fig. 22 Another structural diagram from another angle, Fig. 22 and Fig.23 As shown, in another implementation, the second wire connection part and the second connection foot 3102 both include a copper bar 700, and the copper bar 700 of the second connection foot 3102 includes a plurality of contacts 701, and the plurality of contacts 701 are all in contact with the copper bar 700 of the second wire connection part, so as to realize the connection between the second connection foot 3102 and the second wire connection part. Obviously, at this time, the two copper bars 700 are connected in a sliding manner. Exemplarily, the contacts 701 are stamped on the corresponding copper bars 700.

[0128] In one implementation, the connector 30 further includes an elastic reset member 43, which is located in the connector housing 34, and the elastic reset member 43 is located on the side of the first section 331 of the driving rod 33 away from the second section 332, one end of the elastic reset member 43 abuts against the inner wall of the connector housing, and the other end of the elastic reset member 43 abuts against the driving rod 33. When the movable electrical connector 31 is electrically connected to the power terminal 20, the elastic reset member 43 is in a compressed state, so that after the locking of the driving rod 33 position is released, the driving rod 33 can be reset and maintained at a position where the movable electrical connector 31 disconnects the electrical connection between the connector 30 and the power terminal 20 under the action of the elastic reset member 43, thereby reducing the occurrence of the movable electrical connector 31 accidentally conducting the electrical connection between the connector 30 and the power terminal 20. Exemplarily, the elastic reset member 43 can be a spring.

[0129] Fig.24 This is a schematic diagram of the structure of a connector 30 provided in an embodiment of the present application after being cut open. Fig.25 for Fig.24 A schematic diagram of the structure from another angle, Fig.26 for Fig.24 The structure shown is a schematic diagram after omitting some structures. It is worth noting that Figure 24-26 The installation compartment 343 and the push-pull handle 302 are not shown. Figure 24-26 , the inner wall of the second housing 3403 has a first limiting portion 3413 and a second limiting portion 3414. Further, the portion of the driving rod 33 located in the second housing 3403 includes a third limiting portion 335 and a fourth limiting portion 336, wherein the third limiting portion 335 is opposite to the first limiting portion 3413, and the fourth limiting portion 336 is opposite to the second limiting portion 3414. When the first limiting portion 3413 abuts against the third limiting portion 335, the connector 30 is electrically connected to the power terminal 20, and when the second limiting portion 3414 abuts against the fourth limiting portion 336, the connector 30 is electrically disconnected from the power terminal 20. Exemplarily, the first limiting portion is closer to the second end face of the connector housing than the third limiting portion, and the fourth limiting portion is closer to the second end face of the connector housing than the second limiting portion. It is not difficult to understand that, in a specific implementation, the specific forms of the first limiting portion 3413, the second limiting portion 3414, the third limiting portion 335 and the fourth limiting portion 336 are not limited. For example, the first limiting portion 3413, the second limiting portion 3414, the third limiting portion 335 and the fourth limiting portion 336 can all be step surfaces, or other forms of limiting protrusions such as bosses.

[0130] Next, please refer to Fig.18, the second housing 3403 includes a first portion 3404 and a second portion 3405 arranged relatively along the third direction, and the first portion 3404 and the second portion 3405 are snap-fitted to form the above-mentioned second housing 3403. Exemplarily, in a specific implementation, the first portion 3404 and the second portion 3405 have the same size in the third direction to facilitate the installation of internal components of the second housing 3403. In a specific implementation, the interior of the first portion 3404 and the second portion 3405 can be a symmetrical structure, that is, the first limiting portion 3413 and the second limiting portion 3414 both include a portion located in the first portion 3404, and a portion located in the second portion 3405.

[0131] Furthermore, if Fig. 27 As shown, the first housing 3402 is formed with an installation chamber 343, and the end of the installation chamber 343 opposite to the power terminal 20 has a first opening. The connector 30 includes a push-pull handle 302, which is fixedly connected to the drive rod 33, and the push-pull handle 302 is slidably arranged in the installation chamber 343 along the first direction through the first opening. The length of the accommodating cavity of the installation chamber 343 along the first direction is less than the length of the push-pull handle 302 along the first direction, and the end of the push-pull handle 302 away from the power terminal 20 is exposed in the installation chamber 343. In this way, when the push-pull handle 302 slides along the first direction, the push-pull handle 302 drives the drive rod 33 to move along the first direction. In other words, the push-pull handle 302 can drive the drive rod 33 to move along the first direction A, thereby making the operation more convenient.

[0132] Please combine Fig.13 and Fig.15In some embodiments, the push-pull handle 302 includes a handle body 3021 and a protrusion 3023, and the protrusion 3023 is fixedly connected to the handle body 3021 or integrally formed. The mounting bin 343 includes two groups of limiting holes, and the number of limiting holes in each group of limiting holes is the same as the number of protrusions 3023. For example, if the handle body 3021 is connected to one protrusion 3023, then each group of limiting holes includes one limiting hole; if the handle body 3021 is connected to two protrusions 3023, then each group of limiting holes includes two limiting holes, and the two limiting holes in each group of limiting holes correspond to the two protrusions 3023 one by one. Exemplarily, the limiting holes in one group of limiting holes are connection limiting holes, and the limiting holes in the other group of limiting holes are disconnection limiting holes, and the connection limiting holes and the disconnection limiting holes are arranged in a direction away from the power terminal. When the first limiting portion 3413 abuts against the third limiting portion 335, the protrusion 3023 is engaged with the connection limiting hole, and the connector 30 is electrically connected to the power terminal 20. When the second limiting portion 3414 abuts against the fourth limiting portion 336, the protrusion 3023 is engaged with the disconnection limiting hole, and the electrical connection between the connector 30 and the power terminal 20 is disconnected. When there is no contact between the first limiting portion and the third limiting portion and no contact between the second limiting portion and the fourth limiting portion, the protrusion 3023 abuts against the installation compartment 343.

[0133] Please continue to refer to Fig.15 In a specific embodiment, the handle body 3021 and the raised portion 3023 are integrally formed, and a hollow portion extending along the first direction A is included between the handle body 3021 and the raised portion 3023. For example, the handle body 3021 includes an oblong hole 3022 extending along the first direction A, and the oblong hole 3022 penetrates the handle body 3021 along the second direction C, thereby forming the above-mentioned hollow portion. Furthermore, the raised portions 3023 are provided on both sides of the handle body 3021 in the third direction D, and the two raised portions 3023 are arranged opposite to each other in the third direction D, and the two raised portions 3023 extend in a direction away from the other raised portion 3023. The handle body 3021 is made of an elastic material, and the handle body 3021 includes a hollow portion extending along the first direction A, so that the portion of the handle body 3021 where the protrusion 3023 is located can be deformed under the action of an external force, and the protrusion 3023 can be engaged with the corresponding limiting hole, and can also be separated from the corresponding limiting hole. It is worth noting that when the protrusion 3023 is separated from the corresponding limiting hole, a sudden change in force can be generated during pulling, so that the movable electrical connector 31 can be quickly withdrawn, thereby further reducing the possibility of arc generation.

[0134] Fig.28 A schematic diagram of the structure of another push-pull handle 302 provided in an embodiment of the present application is shown in FIG. Fig.28As shown, in another specific embodiment, the push-pull handle 302 includes a spring 3025, the spring 3025 includes a curved portion, the curved portion is the above-mentioned protrusion 3023, and a avoidance space extending along the first direction is formed between the spring 3025 and the handle body 3021. Exemplarily, the above-mentioned spring 3025 includes but is not limited to a metal spring. Specifically, two metal springs are arranged on both sides of the handle body 3021 in the third direction D, and the above-mentioned avoidance space is formed between each metal spring and the handle body 3021. The service life of the metal spring is longer, and the push-pull handle 302 is fixed by the metal spring and the limiting hole on the installation bin 343, which is conducive to increasing the long-term reliability of the connector 30. Exemplarily, the two springs 3025 are an integrally formed structure, and the handle body 3021 and the two springs 3025 are integrally formed by injection molding to improve the connection reliability between the handle body 3021 and the spring 3025.

[0135] Fig.29 Another structure of a connector 30 provided in an embodiment of the present application is as follows: Fig.30 for Fig.29 Schematic diagram of the structure after partial sectioning. Fig.31 for Fig.30 A top view of the Figure 29-Figure 31 As shown, in other embodiments, a limit block 3410 is provided on the connector housing 34, the mounting chamber 343 includes a second opening, and the limit block 3410 is arranged opposite to the second opening. A connection limit opening 3410b and a disconnection limit opening 3410a are formed between the limit block 3410 and the mounting chamber 343, and the push-pull handle 302 also includes a protrusion 3023. When the first limit portion 3413 abuts against the third limit portion 335, the protrusion 3023 is clamped in the connection limit opening 3410b, and when the second limit portion 3414 abuts against the fourth limit portion 336, the protrusion 3023 is clamped in the disconnection limit opening 3410a. Figure 32-Figure 34 shown.

[0136] Further, in some embodiments, the push-pull handle 302 is made of an elastic material, for example, the push-pull handle 302 is made of plastic. Further, a hollow portion extending along the first direction is included between the handle body 3021 and the protrusion 3023. Exemplarily, the hollow portion can be an oblong hole 3022 or a square hole extending along the first direction A. The handle body 3021 is provided with protrusions 3023 on both sides of the third direction D, and the two protrusions 3023 are arranged relative to each other in the third direction D, and the two protrusions 3023 extend in a direction away from the other protrusion 3023. Further, the orthographic projections of the two protrusions 3023 on the installation chamber 343 along the third direction D are located within the range of the orthographic projections of the hollow portion on the installation chamber 343 along the third direction D. The side walls of the installation chamber 343 located in the third direction all have a second opening, and the second opening allows the installation chamber 343 to communicate with the outside. There is a gap between the orthographic projection of the limiting block 3410 on the installation bin 343 along the third direction D and the orthographic projection of the second opening on the installation bin 343 along the third direction D at both ends in the first direction. Specifically, the end of the limiting block 3410 facing the first opening of the installation bin 343 is the first limiting end, and the first limiting end and the installation bin 343 jointly define a disconnection limiting opening 3410a. The end of the limiting block 3410 facing away from the first opening of the installation bin 343 is the second limiting end, and the second limiting end and the installation bin 343 jointly define a connection limiting opening 3410b.

[0137] Furthermore, the surface parallel to both the first direction and the third direction is the first plane, and the cross section of the protrusion 3023 on the surface parallel to the first plane is a triangle. Along the first opening of the installation chamber 343 pointing to the direction of one end of the installation chamber 343 close to the power terminal 20, the distance between the first limiting end of the limit block 3410 and the center line m of the installation chamber 343 gradually increases, and the distance between the second limiting end of the limit block 3410 and the center line m of the installation chamber 343 gradually decreases. In this way, the position of the driving rod 33 can be fixed at the corresponding position through the joint action of the limit block 3410 and the protrusion 3023, and when the electrical connection between the connector 30 and the power terminal 20 is disconnected, the sudden change of force generated when the protrusion 3023 is pulled can be used to make the movable electrical connector 31 quickly withdraw, thereby further reducing the possibility of arc generation.

[0138] Fig.35 A schematic diagram of the structure of a connector 30 provided in an embodiment of the present application is shown in FIG. Fig.36 for Fig.35 The structural diagram of the push-pull handle 302 is as follows: Fig.35 and Fig.36As shown, a status display window 3409 is provided on the installation compartment 343, and an electrical connection mark 305 and a disconnection mark 306 are provided on the surface of the push-pull handle 302. When the first limit portion 3413 abuts against the third limit portion 335, the connector 30 is electrically connected to the power terminal 20, and the push-pull handle 302 drives the electrical connection mark 305 to move to the status display window 3409, so as to expose the electrical connection mark 305 through the status display window 3409. When the second limit portion 3414 abuts against the fourth limit portion 336, the electrical connection between the connector 30 and the power terminal 20 is disconnected, and the push-pull handle 302 drives the disconnection mark 306 to move to the status display window 3409, so as to expose the disconnection mark 306 through the status display window 3409. Thus, the operator can observe the electrical connection state between the connector 30 and the power terminal 20 from the outside, which is more convenient for the operator to observe.

[0139] Fig.37 A schematic diagram of the structure of a connector 30 provided in an embodiment of the present application is shown in FIG. Fig.38 for Fig.37 The connector 30 shown is a schematic diagram after some structures are omitted. Fig.37 and Fig.38 As shown, a status display window 3409 is provided on the installation compartment 343. Exemplarily, the status display window 3409 can be located at one end of the installation compartment 343 away from the power terminal 20. The side of the push-pull handle 302 along the first direction includes a toggle portion 3024, and the connector housing 34 is provided with an electrical connection mark 305 and a disconnection mark 306 that are transmission-connected to the toggle portion 3024. When the first limiting portion 3413 abuts against the third limiting portion 335, the toggle portion 3024 drives the electrical connection mark 305 to move to the status display window 3409, so as to expose the electrical connection mark 305 through the status display window 3409; when the second limiting portion 3414 abuts against the fourth limiting portion 336, the toggle portion 3024 drives the disconnection mark 306 to move to the status display window 3409, so as to expose the disconnection mark 306 through the status display window 3409. Exemplarily, the connector 30 further includes a toggle bar 304 in a bent structure, which is rotatably disposed on the connector housing 34. An electrical connection mark 305 and a disconnection mark 306 are connected to an end of the toggle bar 304 that is away from the power terminal 20.

[0140] For example, Fig.39As shown, the first housing 3402 includes a sub-housing 3406 and a display assembly cover 3407, the sub-housing 3406 has a accommodating chamber, the accommodating chamber is located on the side of the push-pull handle 302 along the first direction, and the accommodating chamber is open at one end of the push-pull handle 302 and the end opposite to the second housing 3403, the display assembly cover 3407 and the sub-housing 3406 jointly enclose a display assembly accommodating chamber 3408, and the display assembly accommodating chamber 3408 has a fourth opening at one end of the push-pull handle 302. The toggle bar 304, the electrical connection mark 305 and the disconnection mark 306 are all arranged in the display assembly accommodating chamber 3408, and the toggle bar 304 and the connection mark are mechanically connected to each other. Exemplarily, the toggle bar 304 is rotatably arranged in the display assembly accommodating chamber 3408, and the direction of the axis of the toggle bar 304 rotation is perpendicular to the bottom surface of the accommodating chamber. In the area where the fourth opening is located, the toggle bar 304 is transmission-connected to the toggle portion 3024.

[0141] For further information, please refer to Fig.38 , the electrical connection mark 305 and the disconnection mark 306 together form an arc structure. The display component storage compartment 3408 includes a notch portion 3401 (that is, the sub-housing 3406 has a notch portion 3401), and the notch portion 3401 is located at the end of the display component storage compartment 3408 away from the power terminal 20, and the notch portion 3401 is the above-mentioned state display window 3409. In the process of the toggle portion 3024 moving along the first direction A with the push-pull handle 302, the toggle bar 304 rotates relative to the connector housing 34 under the pushing action of the toggle portion 3024 to switch the connection mark opposite to the notch portion 3401. Specifically, when the first limiting portion 3413 abuts against the third limiting portion 335, the toggle portion 3024 drives the electrical connection mark 305 to move to the notch portion 3401 to expose the electrical connection mark 305 through the notch portion 3401; when the second limiting portion 3414 abuts against the fourth limiting portion 336, the toggle portion 3024 drives the disconnection mark 306 to move to the notch portion 3401 to expose the disconnection mark 306 through the notch portion 3401.

[0142] Please continue to refer to Fig.37 In another implementation, the display assembly cover 3407 is provided with an observation hole, which is the above-mentioned state display window 3409. When the first limit portion 3413 abuts against the third limit portion 335, the toggle portion 3024 drives the electrical connection mark 305 to move to the observation hole, so as to expose the electrical connection mark 305 through the observation hole; when the second limit portion 3414 abuts against the fourth limit portion 336, the toggle portion 3024 drives the disconnection mark 306 to move to the observation hole, so as to expose the disconnection mark 306 through the observation hole.

[0143] In some embodiments, the connector 30 has any two of the above-mentioned settings, so that the operator can observe the electrical connection state between the connector 30 and the power terminal 20 from multiple directions, which is more convenient for the operator to observe. Specifically, in this case, the electrical connection mark 305 includes a first mark surface and a second mark surface, the first mark surface is used to be opposite to the observation hole, and the second mark surface is used to be opposite to the notch portion 3401. The disconnection mark 306 includes a third mark surface and a fourth mark surface, the third mark surface is used to be opposite to the observation hole, and the fourth mark surface is used to be opposite to the notch portion 3401.

[0144] Of course, in other embodiments, the connector 30 may also be other combinations of the aforementioned three settings, which are not listed here one by one.

[0145] In some embodiments, the electrical connection mark 305 and the disconnection mark 306 are integrally connected.

[0146] Fig.40 A schematic diagram of the structure of a connector assembly provided in the present application, wherein a board-end connector 90 and a line-end connector 80 are in a connected state; Fig.41 for Fig.40 The connector assembly shown is a schematic diagram of the structure in which the board-side connector 90 and the line-side connector 80 are in a separated state. Fig.40 and Fig.41 As shown, an embodiment of the present application further provides a connector assembly, which includes a board-end connector 90 and a line-end connector 80, wherein the board-end connector 90 has a accommodating cavity, and the accommodating cavity has a third opening. The side wall of the board-end connector 90 has a snap-in hole 91, and the snap-in hole 91 is connected to the accommodating cavity. In a specific implementation, the snap-in hole 91 can be a through hole or a blind hole. For ease of processing, in a specific implementation, the snap-in hole 91 is a through hole. Further, the line-end connector 80 includes a main body 81 and a line-end protrusion 82, and the line-end protrusion 82 is fixed or integrally formed with the main body 81. When the line-end protrusion 82 is snap-fitted with the snap-in hole 91, the board-end connector 90 is electrically connected to the line-end connector 80. When the wire end protrusion 82 is located between the clamping hole 91 and the third opening, the wire end protrusion 82 abuts against the side wall of the board-end connector 90. When the wire end protrusion 82 is separated from the board-end connector 90, the electrical connection between the board-end connector 90 and the wire end connector 80 is disconnected. In this solution, the board-end connector 90 and the wire end connector 80 are pluggable and connected through the wire end protrusion 82 and the clamping hole 91, which is conducive to realizing the rapid plugging and unplugging of the wire end connector 80 in the board-end connector 90. In the application scenario of live plugging and unplugging of the wire end connector 80, rapid plugging and unplugging can reduce the generation of arcs, which is conducive to increasing the reliability of the product.

[0147] Fig.42 for Fig.40 A cross-sectional view of the connector assembly is shown. Fig.42 As shown, in a specific implementation, the main body 81 can be a rectangular parallelepiped or a shape similar to a rectangular parallelepiped, and the line end protrusion 82 can be one, two or three. Taking the case where the main body 81 is a rectangular parallelepiped or a shape similar to a rectangular parallelepiped and there are two line end protrusions 82 as an example, as shown in FIG. Fig.42 As shown, the two wire end protrusions 82 can be respectively opposite to one of a pair of opposite side walls of the main body 81. It should be understood that the snap-in holes 91 on the side walls of the board-end connector 90 correspond one-to-one to the wire end protrusions 82. When the two wire end protrusions 82 are snap-fitted with the snap-in holes 91 corresponding to the wire end protrusions 82, the board-end connector 90 and the wire end connector 80 are electrically connected. Furthermore, the above-mentioned two wire end protrusions 82 can be symmetrically arranged about the axis of the wire end connector 80, or can be asymmetrically arranged about the axis of the wire end connector 80, depending on actual needs. It is worth noting that when the two wire end protrusions 82 are symmetrically arranged about the axis of the wire end connector 80, the force on the wire end connector 80 during the plugging and unplugging process is more balanced, which is more conducive to the rapid plugging and unplugging of the wire end connector 80.

[0148] Fig.43 Schematic diagram of the structure of the line end connector 80 in the connector assembly of the present application. Fig.43 As shown, the side wall of the line end connector 80 has at least one pair of hollow long grooves 83 arranged at intervals, and each hollow long groove 83 extends along the plugging and unplugging direction of the line end connector 80. Each line end protrusion 82 corresponds to a pair of hollow long grooves 83, and the line end protrusion 82 is located between the corresponding two hollow long grooves 83.

[0149] Please continue to refer to Fig.42 In some embodiments, the main body 81 of the wire end connection part and the wire end protrusion 82 are integrally formed, and a hollow portion 84 extending along the plugging and unplugging direction of the wire end connector 80 is included between the main body 81 and the wire end protrusion 82. When the wire end connector 80 is inserted into or unplugged from the board end connector 90, the wire end protrusion 82 moves toward the hollow portion 84, and the inertial force generated by this deformation is conducive to the rapid plugging and unplugging of the wire end connector 80 in the board end connector 90.

[0150] Fig.44 Schematic diagram of the structure of the line end connector 80 in the connector assembly of the present application. Fig.44As shown, in other embodiments, the line end connector 80 includes a spring 85, and the spring 85 includes a bent portion, which is a line end protrusion 82, and an avoidance space 86 is formed between the line end protrusion 82 and the main body 81. Exemplarily, the spring 85 is a metal spring, and the metal spring has a longer service life. The connection and fixation between the board end connector 90 and the line end connector 80 are achieved by the metal spring and the clamping hole 91 of the board end connector 90, which is conducive to increasing the long-term reliability of the connector assembly. Exemplarily, the two springs 85 are an integrally molded structure, and the line end protrusion of the line end connector 80 and the two springs 85 are injection molded as a whole to improve the connection reliability between the line end protrusion and the spring 85.

[0151] Please continue to refer to Fig.41 The inner wall of the board-end connector 90 has a guide groove 92 corresponding to the wire-end protrusion 82. That is to say, the wire-end protrusion 82 not only plays a role of clamping and quick separation together with the clamping hole 91, but also plays a guiding role together with the guide groove 92, so that the plugging and unplugging of the wire-end connector 80 are more convenient.

[0152] Exemplarily, the board-side connector 90 and the line-side connector 80 each include at least two electrical connectors, and the at least two electrical connectors of the board-side connector 90 correspond one-to-one to the at least two electrical connectors of the line-side connector 80. The arrangement of each electrical connector is not described in detail here.

[0153] An electronic device provided by the present application includes a device case, a power circuit accommodated in the device case, and the above-mentioned connector assembly, wherein the device case includes at least one board-end slot, and at least one board-end connector is fixed in each board-end slot. Each of the at least one board-end connector is electrically connected to the power circuit, and each board-end connector is pluggable and connected to the line-end connector corresponding to the board-end connector. In this solution, the board-end connector and the line-end connector are pluggable and connected to the card hole through the line-end protrusion, which is conducive to realizing the rapid plugging and unplugging of the line-end connector in the board-end connector. In the application scenario of live plugging and unplugging of the line-end connector, rapid plugging and unplugging can reduce the generation of electric arcs, which is conducive to increasing the reliability of the product.
