Description

Technical Field

[0001] The present application relates to the technical field of electrical devices, and in particular to a power supply device. Background Art

[0002] 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.

[0003] 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

[0004] An embodiment of the present application provides a power supply device, which can improve the situation of hot plugging and unplugging of a connector.

[0005] A power supply device provided in an embodiment of the present application includes a power supply housing, a power circuit, a plurality of power terminals and at least one connector, wherein the power supply housing is used to accommodate the power circuit, the plurality of power terminals are electrically connected to the power circuit respectively, each of the power terminals is exposed from the power supply housing, each of the connectors is used to be pluggable and connected to one of the power terminals, and each of the connectors includes a movable electrical connector, a transmission device, a driving rod and a connector housing, wherein:

[0006] The connector housing is used to accommodate the movable electrical connector and the transmission device, and the transmission device is used to transmit and connect the driving rod and the movable electrical connector;

[0007] The driving rod is used to move relative to the connector housing along a first direction and drive the movable electrical connector to connect or disconnect the electrical connection between the connector and the power terminal. The first direction is parallel to the plugging and unplugging direction of the connector.

[0008] In this solution, when the driving rod moves along the first direction, the transmission device 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, the transmission device 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. In other words, when the power supply device provided by this embodiment is used, the power supply of the connector can be realized by moving the driving rod along the first direction. 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 live plugging and unplugging of the connector can be avoided, thereby avoiding the impact of the live plugging and unplugging of the connector on the service life of the connector and the power terminal. 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 power supply device provided by this solution, plugging and unplugging a connector does not require suspending 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 power supply device 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 controlling the cost of the power supply device, reducing the operating complexity of the power supply device, and reducing the possibility of staff misoperation.

[0009] In addition, the moving direction of the driving rod, that is, the first direction mentioned above, is parallel to the plugging and unplugging direction of the connector, which is easier for the staff to remember and operate.

[0012] The driving rod moves along a direction in which the connector is inserted into the power terminal, and the driving rod drives the movable electrical connection member to conduct electrical connection between the connector and the power terminal.

When the electrical connection between the connector and the power terminal is connected, the movement direction of the driving rod is parallel to the movement direction of the connector when the connector is inserted into the power terminal.

DETAILED DESCRIPTION

[0055] The power supply device includes a power supply housing, a power terminal and a connector, wherein the power terminal is fixed to the power supply housing, and the connector is used to connect the load device through a cable and connect it to the power terminal. When the power supply device is used, the electrical connection between the load device and the power supply device is achieved by plugging and unplugging the connector and the power terminal. However, during the use of the power supply device, the connector may be plugged and unplugged while powered on due to misoperation and other reasons, and plugging and unplugging the connector while powered on will cause arcing, which will not only affect the service life of the connector and the power terminal, but also put the staff at risk of electric shock.

[0056] Based on this, the embodiment of the present application provides a power supply device to solve the above problems. In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings.

[0057] In the embodiments of the present application, the power supply device includes a blade power supply, a photovoltaic inverter, a photovoltaic optimizer or an energy storage converter, etc.

[0060] 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 2 As 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. Each connector 30 is pluggably connected to a power terminal 20. Figure 3 A cross-sectional view of a connector in a power supply device provided in an embodiment of the present application. Figure 3As shown, each connector 30 includes a movable electrical connector 31, a transmission device 32, a drive rod 33 and a connector housing 34. The connector housing 34 accommodates the movable electrical connector 31 and the transmission device 32. The transmission device 32 transmits and connects the drive rod 33 and the movable electrical connector 31. The drive rod 33 is used to move relative to the connector housing 34 along a first direction A and drive the movable electrical connector 31 to connect or disconnect the electrical connection between the connector 30 and the power terminal 20. 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 transmission device 32 can drive the movable electrical connector 31 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 transmission device 32 can drive the movable electrical connector 31 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 powered on or off 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 impact 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.

[0061] 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.

[0062] 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.

[0063] 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.

[0064] Figure 4 for Figure 2 The enlarged view of the power supply device at B is shown in the figure. Figure 4 As shown, when each power terminal 20 is specifically set, each power terminal 20 includes two power connectors 21, one of the two power connectors 21 is used to connect the positive output terminal of the power circuit, and the other of the two power connectors 21 is used to connect the negative output terminal of the power circuit, and the two power connectors 21 are arranged at intervals along the second direction C perpendicular to the first direction A. 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.

[0065] Figure 5 A schematic diagram of the connection relationship between a connector and a power terminal in a power supply device provided in an embodiment of the present application, Figure 6 for Figure 5 Exploded diagram of Figure 5 and Figure 6As shown, in a specific implementation, a buckle 22 is installed at one end of the power terminal 20 for connecting with the connector 30, and the buckle 22 is rotatably connected to the power terminal 20. A board end sealing ring 50 may be sleeved on the connector housing, and the connector 30 is sealed and connected to the power terminal 20 through the board end sealing ring 50. Further, one end of the connector 30 for connecting with the power terminal 20 includes a clamping block 301. After the connector 30 is plugged into the power terminal 20, the buckle 22 is clamped with the clamping block 301, thereby achieving the connection and fixation between the connector 30 and the power terminal 20, and ensuring the reliable connection between the connector 30 and the power terminal 20.

[0066] Figure 7 A simplified structural diagram of a power supply device provided in an embodiment of the present application is shown in FIG. Figure 7 As shown, the power supply housing 10 includes a top plate 11, a bottom plate (not shown in the figure), a back plate (not shown in the figure) and a cover plate 14, wherein the top plate 11 and the bottom plate are stacked along a first direction A, the back plate and the cover plate 14 are stacked along a second direction C, and the spacing between the back plate and the cover plate 14 is smaller than the spacing between the top plate 11 and the bottom plate. A plurality of power terminals 20 are sequentially spaced along a third direction D on the bottom plate of the power supply housing 10, and the side of the back plate facing away from the cover plate 14 includes a mounting surface, and the mounting surface is used to fix the power supply device.

[0067] Figure 8 A cross-sectional view of a connector in a power supply device provided in an embodiment of the present application, such as Figure 8 As shown, the connector housing 34 includes a first end face 341 and a second end face 342 arranged opposite to each other along a first direction A. Specifically, the first end face 341 of the connector housing 34 includes a drive rod mounting hole 3411, which penetrates the first end face 341 along the first direction A, and the axis of the drive rod mounting hole 3411 overlaps with the axis of the drive rod 33. The drive rod mounting hole 3411 is used to accommodate the movement of the drive rod 33 relative to the second end face 342 along the first direction A, or the movement of the drive rod 33 away from the second end face 342 along the first direction A. The second end face 342 includes a connector communication hole 3421, which penetrates the second end face 342 along the first direction A, so that the power connector 21 can be electrically connected to the connector 30. Obviously, the number of the connector communication holes 3421 is not less than the number of the power connectors 21, and each power connector 21 has a corresponding connector communication hole 3421.

[0068] Please continue to refer to Figure 8In one implementation, the connector 30 includes a sealing ring 35, which is sleeved on the outer periphery of the driving rod 33 and fixedly connected to the driving rod 33. The driving rod 33 is sealed with the driving rod mounting hole 3411 through the sealing ring 35 to ensure reliable sealing of the connector housing 34. In this embodiment, the connector can achieve IP65 protection level protection.

[0069] In a specific implementation, the connector housing 34 is used to partially accommodate the driving rod 33, and the driving rod 33 includes a first section 331 and a second section 332 arranged relatively along the first direction A, wherein the first section 331 is used to drive the movable electrical connector 31 through the transmission device 32, and the second section 332 is used to receive the driving force and drive the driving rod 33 to move along the first direction A. It is not difficult to understand that the first section 331 is fixedly connected to the second section 332.

[0070] Combine the following Figure 8 The specific structure of the connector 30 in a power supply device provided in an embodiment of the present application is introduced. Figure 8 As shown, the connector 30 also includes a fixed electrical connector 37, which is used to electrically connect to one of the two power connectors 21 of the power terminal 20, and the movable electrical connector 31 is used to electrically connect or disconnect to the other of the two power connectors 21 of the power terminal 20, so as to achieve the connection or disconnection of the electrical connection between the connector 30 and the power circuit of the power supply device. Obviously, the arrangement direction of the fixed electrical connector 37 and the movable electrical connector 31 is parallel to the arrangement direction of the two power connectors 21 of the power terminal 20. Exemplarily, the fixed electrical connector 37 is an elastic conductive clip.

[0071] 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 8 As 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.

[0072] In one technical solution, the driving rod 33 and the transmission device 32 are arranged at intervals along the second direction C.

In one implementation, the transmission device 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 device 32 are arranged in sequence along the first direction A, this solution is conducive to simplifying the structure of the transmission device 32. Of course, according to actual needs, the electrical connection unit 400, the cable connection unit 500 and the transmission device 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 .

[0075] 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.

[0076] 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 .

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.

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.

[0078] 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.

[0079] 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.

[0080] 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.

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.

[0083] 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.

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.

[0084] 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.

[0085] 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.

[0086] 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. Figure 8 and Fig.17 As shown, in one implementation, the transmission device 32 includes a driving arm 321, a transmission arm 322 and a connecting arm 323, the driving arm 321 is rotatably connected to the first section 331, and the driving arm 321 and the transmission arm 322 are arranged at an angle and fixedly connected, and the driving arm 321 and the transmission arm 322 are both rotatably connected to the connector housing 34 through the first rotating shaft 100 at the connection between the two. The end of the transmission arm 322 away from the driving arm 321 is hinged to the connecting arm 323, and the end of the connecting arm 323 away from the transmission arm 322 is hinged to the movable electrical connector 31 through the second rotating shaft 200, and the movable electrical connector 31 is rotatably connected to the connector housing 34 through the third rotating shaft 300. When the transmission arm 322 and the connecting arm 323 form a preset angle, the movable electrical connector 31 is electrically connected to the intermediate electrical connector 44, and the transmission arm 322 can no longer drive the connecting arm 323, that is, the transmission arm 322 and the connecting arm 323 are both at the transmission dead point position.

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.

[0088] 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.

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.

[0096] 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.
