Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0068] In the description of the present application, "plurality" means more than two, and unless otherwise clearly and specifically defined, "more than two" includes two. Accordingly, "multiple groups" means more than two groups, including two groups.

For example, A and / or B can represent: A exists, A and B exist at the same time, and B exists. In addition, in this application, the character " / " generally indicates that the associated objects before and after are in an "or" relationship.

[0071] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0072] In the related art, a connector assembly can be used as a mating structure to connect two devices to achieve electrical connection between the two devices. Specifically, the connector assembly includes two connectors, which are respectively assembled on the two devices and mated with each other to achieve electrical connection between the two devices.

[0073] For example, the two devices may be a battery and a vehicle body, respectively, and the connector assembly is connected to the battery and the high-voltage control box of the vehicle body. Based on this, for example, during a battery replacement process, it is usually necessary to assemble the battery to the vehicle body so that the relative positions of the battery and the high-voltage control box are fixed. In addition, the connector assembly on the battery and the connector assembly on the high-voltage control box are mated with each other to achieve electrical connection between the battery and the high-voltage control box.

[0074] However, there are manufacturing errors in the connector, battery and high-voltage control box during the manufacturing process, which makes it difficult for the connector components to be accurately mated with each other.

[0075] In some cases, springs and guide columns are provided on the connector so that the connector can float relative to the battery and the high-voltage control box. The guiding effect of the guide columns can offset the above-mentioned manufacturing errors to a certain extent, thereby improving the mating accuracy of the connector assembly.

[0076] However, this makes the cost of the connector assembly higher.

[0077] Based on the above considerations, the embodiment of the present application provides a connector assembly and an electric power device, wherein the first connector of the connector assembly is used to be assembled to the first device after the first connector and the second connector are plugged and matched, and / or the second connector of the connector assembly is used to be assembled to the second device after the first connector and the second connector are plugged and matched. In this way, during the plugging and matching process of the first connector and the second connector, the first connector is not assembled to the first device, or the second connector is not assembled to the second device, or the first connector is not assembled to the first device, and the second connector is not assembled to the second device. It can be understood that at this time, the positions of the first connector and the second connector are not relatively fixed, so that the first connector and the second connector can float relatively, so that the plugging and matching effect can be accurately achieved. After the first connector and the second connector are plugged and matched, the first connector is assembled to the first device, or the second connector is assembled to the second device, or the first connector is assembled to the first device, and the second connector is assembled to the second device. Thereby, the relative fixation of the first connector and the second connector is achieved to maintain the plugging relationship between the first connector and the second connector. Therefore, there is no need to set springs, guide columns and other structures on the connector assembly, so as to offset at least one of the manufacturing errors of the first connector, the second connector, the first device and the second device to a certain extent, and the cost is low.

[0078] The connector assembly involved in the embodiment of the present application can be used in an electric device, wherein the electric device can be a device using a battery as a power source.

[0079] A battery may be a single physical module that includes one or more battery cells to provide higher voltage and capacity.

[0080] The power device may include a first device, a second device and a connector assembly. The connector assembly may serve as a mutual mating structure between the first device and the second device, and is used to connect the first device and the second device to achieve electrical connection between the first device and the second device.

[0081] The electric equipment may be, but is not limited to, vehicles, electric toys, battery cars, ships, spacecraft, excavators, etc. Among them, electric toys may include fixed or mobile electric toys, such as electric car toys, electric ship toys, and electric airplane toys, etc. Spacecraft may include airplanes, rockets, space shuttles, and spacecrafts, etc.

[0082] For the convenience of explanation, some embodiments of the present application are described using the electric equipment as a vehicle as an example.

[0083] See also Figure 1 , Figure 1 Schematic diagram of a vehicle 1000a provided in some embodiments of the present application. According to the power source, the vehicle 1000a can be a pure electric vehicle, a hybrid electric vehicle, or an extended-range vehicle, etc. According to the driving mode, the vehicle 1000a can be a front-wheel drive vehicle, a rear-wheel drive vehicle, or a four-wheel drive vehicle.

[0084] In some embodiments of the present application, the vehicle 1000a may include a battery 300a, and the battery 300a may be used to power the vehicle 1000a. For example, the battery 300a may serve as an operating power source for the vehicle 1000a.

[0085] In some embodiments of the present application, the battery 300a can not only serve as the operating power source of the vehicle 1000a, but also serve as the driving power source of the vehicle 1000a, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000a.

[0086] The vehicle 1000a may further include a controller 200a and a motor 400a. The controller 200a is used to control the battery 300a to supply power to the motor 400a, which can be used for starting, navigating and driving the vehicle 1000a.

[0087] For example, the controller 200a can be used to convert the direct current output by the battery 300a into alternating current and output the alternating current to the motor 400a to control the operation of the motor 400a, thereby realizing the driving control of the vehicle 1000a. For example, the controller 200a can control the start, speed change and stop of the motor 400a to drive the vehicle 1000a to start, change speed and stop.

[0088] For example, the controller 200a can be used to convert AC power into DC power. For example, during the kinetic energy recovery process of the vehicle 1000a, the motor 400a can convert the mechanical energy driving its rotation into AC power, and the controller 200a can convert the AC power into DC power and charge it back to the battery 300a.

[0089] The vehicle 1000a may further include a high voltage control box for controlling the use of the battery 300a.

[0090] See also Figure 2 , Figure 2 The exploded view of the battery 300a provided in some embodiments of the present application. The battery 300a includes a box body 320a and a battery cell 310a.

Among them, the box body 320a composed of the first part 321a and the second part 322a can be a variety of shapes, such as a cylinder, a cuboid, etc.

[0092] In some embodiments, please refer to Figure 1 and Figure 2At least one of the first portion 321a and the second portion 322a of the battery 300a may be used as part of the chassis structure of the vehicle 1000a. For example, a portion of the second portion 322a may become at least a portion of the chassis of the vehicle 1000a, or a portion of the second portion 322a may become at least a portion of the cross beam and the longitudinal beam of the vehicle 1000a.

[0093] In the battery 300a, the number of battery cells 310a can be one or more. When there are multiple battery cells 310a, the multiple battery cells 310a are connected in series, in parallel or in hybrid connection through a busbar component. Hybrid connection means that the multiple battery cells 310a are connected in series and in parallel.

[0094] In some embodiments, a plurality of battery cells 310a may be connected in series, in parallel, or in mixed connection to form a whole, and then the whole formed by the plurality of battery cells 310a is directly accommodated in the internal space of the box body 320a, such as Figure 2 shown.

[0095] In some embodiments, multiple battery cells 310a may also be connected in series, in parallel or in a mixed connection, and arranged and fixed to form multiple battery modules, and multiple battery modules are then connected in series, in parallel or in a mixed connection to form a whole, and accommodated in the internal space of the above-mentioned box body 320a. As an example, multiple battery cells 310a may be fixed to form a battery module by cable ties, etc. As an example, multiple battery cells 310a may also be fixed to form a battery module by end plates, side plates, etc.

The battery cell 310a may be cylindrical, flat, rectangular, or in other shapes.

In some possible designs, such as Figures 3 to 5 As shown, the first connector 10 is an electrical device. Specifically, the first connector 10 is used to electrically connect the first device 200 and the second device 300, and the second connector 20 and the second connector 20 are plugged together to at least achieve the sealing of the connection between the second device 300 and the first connector 10. In some other possible designs, the second connector 20 is an electrical device. Specifically, the second connector 20 is used to electrically connect the first device 200 and the second device 300, and the first connector 10 and the second connector 20 are plugged together to at least achieve the sealing of the connection between the first device 200 and the second connector 20. In some other possible designs, the first connector 10 and the second connector 20 are both electrical devices. Specifically, the first connector 10 is electrically connected to the first device 200, the second connector 20 is electrically connected to the second device 300, and the first connector 10 and the second connector 20 are plugged together to form an electrical connection, thereby achieving the electrical connection between the first device 200 and the second device 300.

[0104] The first direction Z is the plugging direction of the first connector 10 and the second connector 20. Figures 3 to 5 As shown, the first direction Z may be parallel to the Z axis.

[0105] In some possible designs, the second connector 20 is provided with a slot 201, and the first connector 10 is plugged into the slot 201 of the second connector 20 along the first direction Z. In other possible designs, the first connector 10 is provided with the above-mentioned slot 201, and the second connector 20 is plugged into the slot 201 of the first connector 10 along the first direction Z. In some other possible designs, both the first connector 10 and the second connector 20 are provided with the above-mentioned slot 201, and the first connector 10 is plugged into the slot 201 of the second connector 20 along the first direction Z, and the second connector 20 is also correspondingly plugged into the slot 201 of the first connector 10 along the first direction Z. In this way, the plug-in matching of the first connector 10 and the second connector 20 along the first direction Z is achieved.

[0106] In the connector assembly 100 provided in the embodiment of the present application, the first connector 10 of the connector assembly 100 is used to be assembled to the first device 200 after the first connector 10 and the second connector 20 are plugged and matched; or, the second connector 20 of the connector assembly 100 is used to be assembled to the second device 300 after the first connector 10 and the second connector 20 are plugged and matched; or, the first connector 10 of the connector assembly 100 is used to be assembled to the first device 200 after the first connector 10 and the second connector 20 are plugged and matched, and the second connector 20 of the connector assembly 100 is also used to be assembled to the second device 300 after the first connector 10 and the second connector 20 are plugged and matched. In this way, during the plugging and matching process of the first connector 10 and the second connector 20, the first connector 10 is not assembled to the first device 200, or the second connector 20 is not assembled to the second device 300, or the first connector 10 is not assembled to the first device 200, and the second connector 20 is not assembled to the second device 300. It can be understood that at this time, the positions of the first connector 10 and the second connector 20 are not relatively fixed, so that the first connector 10 and the second connector 20 can float relatively, so that the plug-in and mating effect can be accurately achieved. After the first connector 10 and the second connector 20 are plugged and mated, the first connector 10 is assembled to the first device 200, or the second connector 20 is assembled to the second device 300, or the first connector 10 is assembled to the first device 200, and the second connector 20 is assembled to the second device 300. In addition, the first device 200 and the second device 300 are relatively fixed. Thus, the relative fixation of the first connector 10 and the second connector 20 is achieved to maintain the plug-in relationship between the first connector 10 and the second connector 20. Therefore, there is no need to set springs, guide columns and other structures on the connector assembly 100, which can offset the manufacturing error to a certain extent, and the cost is low.

[0107] The manufacturing error may include at least one of the manufacturing errors of the first connector 10 , the second connector 20 , the first device 200 , and the second device 300 .

[0108] The manufacturing error may include at least one manufacturing error along the first direction Z among the manufacturing errors of the first connector 10 , the second connector 20 , the first device 200 , and the second device 300 .

[0109] For example, the above-mentioned manufacturing error may cause deviation of the first connector 10 along a plane intersecting the first direction Z on the first device 200 .

[0110] For another example, the above manufacturing error may cause a deviation of the second connector 20 on the second device 300 along a plane intersecting the first direction Z.

[0111] In addition, by eliminating structures such as springs and guide posts on the connector assembly 100, the design of the connector assembly 100 is greatly simplified, thereby reducing the volume of the connector assembly 100, and further saving the space occupied by the connector assembly 100. Therefore, the volume of the power device 1000 can be reduced, and when the volume of the power device 1000 is predetermined, the power device 1000 can save more space to accommodate other devices.

[0112] As an example, Figures 3 to 5 As shown, when assembling the connector assembly 100 , the first connector 10 can be first assembled to the first device 200 , and then the first connector 10 and the second connector 20 can be plugged and matched along the first direction Z, and finally the second connector 20 can be assembled to the second device 300 .

[0113] As another example, when assembling the connector assembly 100 , the second connector 20 can be first assembled to the second device 300 , and then the first connector 10 and the second connector 20 can be plugged and matched along the first direction Z, and finally the first connector 10 can be assembled to the first device 200 .

[0114] As another example, when assembling the connector assembly 100 , the first connector 10 and the second connector 20 can be first plugged and matched along the first direction Z, and then the first connector 10 can be assembled to the first device 200 , and the second connector 20 can be assembled to the second device 300 .

[0115] In some embodiments, please refer to Figures 4 to 6 , and combined with other drawings. Among them, Figure 6 The third embodiment of the present invention is a three-dimensional structural diagram of the second connector 20 of the connector assembly 100. The second connector 20 is provided with a slot 201, and at least a part of the first connector 10 is plugged into the slot 201.

[0116] The slot 201 refers to a slot on the second connector 20 for plugging and mating with the first connector 10. In some possible designs, such as Figures 4 to 6 As shown, the slot 201 may be a through slot that passes through the second connector 20 along the first direction Z. In some other possible designs, the slot 201 may be a slot that passes through one end of the second connector 20 along the first direction Z, so that at least a portion of the first connector 10 can be plugged into the slot 201 along the first direction Z.

[0117] By adopting the above technical solution, the first connector 10 can be plugged into the slot 201 of the second connector 20 along the first direction Z, so as to achieve plug-in matching between the first connector 10 and the second connector 20 .

[0118] In some embodiments, please refer to Figure 4and Figure 7 , and combined with other drawings. Among them, Figure 7 for Figure 4 The connector assembly 100 further includes a first sealing ring 30 , which is disposed around the outer periphery of the first connector 10 in the first direction Z. Furthermore, the first sealing ring 30 abuts between the outer peripheral wall of the first connector 10 and the inner peripheral wall of the slot 201 .

[0119] The first sealing ring 30 refers to a ring-shaped structure for sealing, wherein the first sealing ring 30 can be a rubber ring, a silicone ring, etc.

[0120] The outer peripheral wall of the first connector 10 refers to the outer peripheral wall of the first connector 10 around the first direction Z. The inner peripheral wall of the slot 201 refers to the inner peripheral wall of the slot 201 around the first direction Z.

[0121] The first sealing ring 30 abuts between the outer circumferential wall of the first connector 10 and the inner circumferential wall of the slot 201, which means that the radial inner circumferential wall of the first sealing ring 30 abuts against the outer circumferential wall of the first connector 10 around the first direction Z, and the radial outer circumferential wall of the first sealing ring 30 abuts against the inner circumferential wall of the slot 201 around the first direction Z.

[0122] The connector assembly 100 has a central axis 1001, which coincides with the central axis 1001 of the first sealing ring 30, and the central axis 1001 is parallel to the axial direction of the first sealing ring 30 and parallel to the first direction Z. The periphery of the first connector 10 around the first direction Z refers to the periphery of the first connector 10 around the central axis 1001. The peripheral wall of the first connector 10 around the first direction Z refers to the peripheral walls of the first connector 10 around the central axis 1001, that is, the peripheral wall of the first connector 10 along the radial direction of the first sealing ring 30.

[0123] The inner circumferential wall of the slot 201 around the first direction Z refers to the inner walls of the slot 201 around the central axis 1001 , that is, the inner circumferential wall of the slot 201 along the radial direction of the first sealing ring 30 .

[0124] In this way, the first sealing ring 30 is arranged between the inner peripheral wall of the slot 201 and the outer peripheral wall of the first connector 10 around the first direction Z, so as to seal the connection between the first connector 10 and the slot 201. In this way, when the manufacturing error includes at least one manufacturing error along the first direction Z of the manufacturing errors of the first connector 10, the second connector 20, the first device 200 and the second device 300, so that the relative position of the first device 200 and the second device 300 caused by the manufacturing error is deviated along the first direction Z, so that the first connector 10 and the second connector 20 also have deviations along the first direction Z, the first sealing ring 30 can still maintain the sealing of the plug-in joint of the first connector 10 and the second connector 20, that is, the connector assembly 100 can also offset at least one manufacturing error along the first direction Z of the manufacturing errors of the first connector 10, the second connector 20, the first device 200 and the second device 300. In addition, when the first connector 10 and the second connector 20 move relative to each other along the first direction Z under vibration or other working conditions, the first sealing ring 30 can still maintain the sealing of the plug-in joint of the first connector 10 and the second connector 20.

[0125] In some embodiments, please refer to Figure 4 and Figure 7 , and in combination with other drawings. A limiting groove 101 is provided on the outer peripheral wall of the first connector 10 along the first direction Z, and at least a portion of the first sealing ring 30 is limited in the limiting groove 101 along the first direction Z.

[0126] like Figure 4 and Figure 7 As shown, the first sealing ring 30 is arranged around the outer peripheral wall of the first connector 10 around the first direction Z, and is at least partially embedded in the limiting groove 101 of the outer peripheral wall of the first connector 10 around the first direction Z, so that at least a portion of the first sealing ring 30 is limited in the limiting groove 101 along the first direction Z.

[0127] With such a configuration, the first sealing ring 30 can be stably assembled on the first connector 10, so as to be stably arranged around the outer circumference of the first connector 10 in the first direction Z, thereby stably maintaining the relative positions of the first connector 10 and the first sealing ring 30 in the first direction Z. In this way, the sealing effect of the first sealing ring 30 on the plug-in connection of the first connector 10 and the second connector 20 can be stably maintained. In addition, the problem of the first sealing ring 30 detaching from the first connector 10 when the first connector 10 and the second connector 20 move relative to each other along the first direction Z under vibration and other working conditions can be improved, so as to stably maintain the sealing of the plug-in connection of the first connector 10 and the second connector 20 by the first sealing ring 30.

[0128] In some embodiments, please refer to Figure 4 , Figure 6 and Figure 7, and in combination with other drawings. The slot 201 passes through the second connector 20 along the first direction Z. The first connector 10 includes a housing 11 and a conductive member 12. The housing 11 is used to connect to the first device 200. The conductive member 12 is disposed in the housing 11 and is used to electrically connect to the first device 200. At least a portion of the housing 11 and at least a portion of the conductive member 12 are plugged into the slot 201, so that the conductive member 12 is electrically connected to the second device 300.

[0129] like Figure 4 and Figure 6 As shown, the slot 201 is a through slot that passes through two opposite ends of the second connector 20 along the first direction Z.

[0130] The housing 11 is a shell structure of the first connector 10 .

[0131] The conductive member 12 is a conductive component of the first connector 10 used for electrical connection and can be a copper bar, a copper column, a wire, or the like.

[0132] It can be understood that after the connector assembly 100, the first device 200 and the second device 300 are assembled, the first connector 10 is assembled to the first device 200 through the housing 11, and the conductive member 12 is electrically connected to the first device 200, thereby realizing the assembly of the first connector 10 and the first device 200. The housing 11 and the conductive member 12 of the first connector 10 are both plugged into the slot 201 of the second connector 20 along the first direction Z, so that the conductive member 12 is electrically connected to the second device 300 through the slot 201. In addition, the second connector 20 is assembled to the second device 300.

[0133] As an example, Figures 3 to 5 As shown, during the assembly of the power device 1000, the housing 11 of the first connector 10 can be first assembled to the first device 200, the conductive member 12 of the first connector 10 can be electrically connected to the first device 200, and the assembly of the first device 200 itself can be completed. Then, the first connector 10 is plugged into the slot 201 of the second connector 20 along the first direction Z. Finally, the second connector 20 is assembled to the second device 300, the conductive member 12 of the first connector 10 is electrically connected to the second device 300, and the assembly of the second device 300 itself is completed. In this way, the electrical connection between the first device 200 and the second device 300 is achieved. Among them, the assembly of the first device 200 itself and the assembly of the second device 300 itself can also be carried out in the last step.

[0134] As another example, during the assembly of the power device 1000, the second connector 20 can be first assembled to the second device 300. Then, the first connector 10 is plugged into the slot 201 of the second connector 20 along the first direction Z. Finally, the housing 11 of the first connector 10 is assembled to the first device 200, the conductive member 12 is electrically connected to the first device 200 and the second device 300 respectively, and the assembly of the first device 200 and the second device 300 is completed. In this way, the electrical connection between the first device 200 and the second device 300 is achieved.

[0135] As another example, during the assembly of the power device 1000, the first connector 10 can be first plugged into the slot 201 of the second connector 20 along the first direction Z. Then, the housing 11 of the first connector 10 is assembled to the first device 200, the second connector 20 is assembled to the second device 300, and the conductive member 12 of the first connector 10 is electrically connected to the first device 200 and the second device 300, respectively. Finally, the assembly operation of the first device 200 and the second device 300 is completed. In this way, the electrical connection between the first device 200 and the second device 300 is achieved.

[0136] There are many ways to electrically connect the conductive member 12 and the first device 200. As an example, the conductive member 12 can be fixed to the copper bar with bolts, and the copper bar is connected to the wire of the first device 200. As another example, the conductive member 12 can be welded to the wire of the first device 200. Correspondingly, the electrical connection method between the conductive member 12 and the second device 300 can also be set in the same way.

[0137] The slot 201 is configured as a through slot that penetrates along the first direction Z, so that the conductive member 12 of the first connector 10 can be plugged into the channel along the first direction Z to be electrically connected to the second device 300, thereby achieving electrical connection between the first device 200 and the second device 300.

[0138] In some embodiments, please refer to Figure 4 , Figure 6 and Figure 7 , and in combination with other drawings. The first connector 10 includes a housing 11, a conductive member 12, and a second sealing ring 13. The housing 11 is used to connect with the first device 200. At least part of the conductive member 12 is disposed in the housing 11, and is used to electrically connect with the first device 200. The second sealing ring 13 is disposed around the outer periphery of the conductive member 12 around the first direction Z, and abuts between the inner peripheral wall of the housing 11 and the outer peripheral wall of the conductive member 12.

[0139] The housing 11 is a shell structure of the first connector 10 .

[0140] The conductive member 12 is a conductive component of the first connector 10 used for electrical connection and can be a copper bar, a copper column, a wire, or the like.

[0141] The second sealing ring 13 refers to a ring-shaped structure for sealing, wherein the second sealing ring 13 can be a rubber ring, a silicone ring, etc.

[0142] The outer peripheral wall of the conductive member 12 refers to the outer peripheral wall of the conductive member 12 around the first direction Z. The inner peripheral wall of the housing 11 refers to the inner peripheral wall of the inner space of the housing 11 for accommodating the conductive member 12 around the first direction Z.

[0143] The second sealing ring 13 abuts between the outer circumferential wall of the conductive part 12 and the inner circumferential wall of the outer shell 11, which means that the radial inner circumferential wall of the second sealing ring 13 abuts against the outer circumferential wall of the conductive part 12 around the first direction Z, and the radial outer circumferential wall of the second sealing ring 13 abuts against the inner circumferential wall of the outer shell 11 around the first direction Z.

[0144] The second sealing ring 13 and the first sealing ring 30 are coaxially arranged, that is, the central axis 1001 of the second sealing ring 13 also coincides with the central axis 1001 of the connector assembly 100, and the central axis 1001 is parallel to the axial direction of the second sealing ring 13 and parallel to the first direction Z. The outer periphery of the conductive member 12 around the first direction Z refers to the surrounding of the conductive member 12 around the central axis 1001. The outer peripheral wall of the conductive member 12 around the first direction Z refers to the outer wall of the conductive member 12 around the central axis 1001, that is, the outer peripheral wall of the conductive member 12 along the radial direction of the second sealing ring 13.

[0145] The inner circumferential wall of the inner space of the shell 11 for accommodating the conductive member 12 around the first direction Z refers to the inner wall around the central axis 1001 of the inner space of the shell 11 for accommodating the conductive member 12, that is, the inner circumferential wall of the inner space of the shell 11 for accommodating the conductive member 12 along the radial direction of the second sealing ring 13.

[0146] In this way, the second sealing ring 13 is disposed between the inner peripheral wall of the housing 11 and the outer peripheral wall of the conductive member 12 around the first direction Z to seal the connection between the housing 11 and the conductive member 12. In this way, the sealing effect of the first connector 10 can be achieved.

[0147] Please also read Figure 3 and Figure 4 , and in combination with other drawings. The power device 1000 provided in the embodiment of the present application includes a first device 200, a second device 300 and a connector assembly 100. The connector assembly 100 is used to connect the first device 200 and the second device 300 to achieve electrical connection between the first device 200 and the second device 300.

[0148] Among them, the connector component 100, the first device 200, and the second device 300 in this embodiment are the same as the connector component 100, the first device 200, and the second device 300 in the previous embodiment. Please refer to the relevant description of the connector component 100, the first device 200, and the second device 300 in the previous embodiment for details, which will not be repeated here.

[0149] The power device 1000 provided in the embodiment of the present application adopts the connector assembly 100 involved in the above embodiments, so that the first connector 10 of the connector assembly 100 is used to be assembled to the first device 200 after the first connector 10 and the second connector 20 are plugged and matched; or, the second connector 20 of the connector assembly 100 is used to be assembled to the second device 300 after the first connector 10 and the second connector 20 are plugged and matched; or, the first connector 10 of the connector assembly 100 is used to be assembled to the first device 200 after the first connector 10 and the second connector 20 are plugged and matched, and the second connector 20 of the connector assembly 100 is also used to be assembled to the second device 300 after the first connector 10 and the second connector 20 are plugged and matched. In this way, during the assembly process of the power device 1000, there is no need to set springs, guide columns and other structures on the connector assembly 100, so that the manufacturing error can be offset to a certain extent, so as to achieve stable and accurate plugging and matching of the first connector 10 and the second connector 20 of the connector assembly 100, and the cost is low. Furthermore, the volume of the connector assembly 100 can be reduced, thereby helping to reduce the volume of the power device 1000. When the volume of the power device 1000 is predetermined, the power device 1000 can save more space to accommodate other devices.

[0150] In some embodiments, please refer to Figure 5 , Figure 8 and Fig. 9 , and combined with other drawings. Among them, Figure 8 A partial top view of a first wall 210 of a first device 200 of an electric power device 1000 provided in some embodiments of the present application, Fig. 9 Partial top view of the first wall 210 of the first device 200 of the power device 1000 provided in some other embodiments of the present application. The two partial top views of the first wall 210 are schematic diagrams of the first wall 210 along the first direction Z, and both schematic diagrams use dotted lines to illustrate the projection outline of the second fixing hole 102 projected onto the first wall 210 along the first direction Z. The first device 200 is provided with a first fixing hole 2001, and the first connector 10 is provided with a second fixing hole 102, and the second fixing hole 102 is used to cooperate with the first fixing hole 2001 for fixing. On the projection plane perpendicular to the first direction Z, the projection area of ​​the first fixing hole 2001 and the projection area of ​​the second fixing hole 102 are different.

[0151] The second fixing hole 102 is used for cooperating and fixing with the first fixing hole 2001, which means that the second fixing hole 102 is used to be fixed to the first fixing hole 2001 by fasteners such as bolts and screws, so as to achieve relative fixation between the first fixing hole 2001 and the second fixing hole 102. The fasteners are inserted into the first fixing hole 2001 and the second fixing hole 102 to achieve cooperating and fixing between the first fixing hole 2001 and the second fixing hole 102, so that the first connector 10 is assembled to the first device 200.

[0152] The first fixing hole 2001 and the second fixing hole 102 are arranged opposite to each other along the first direction Z, that is, the projection of the first fixing hole 2001 along the first direction Z and the projection of the second fixing hole 102 along the first direction Z are at least partially overlapped, so that the fastener can pass through the first fixing hole 2001 and the second fixing hole 102 along the first direction Z to fix the first fixing hole 2001 and the second fixing hole 102.

[0153] The projection area of ​​the first fixing hole 2001 along the first direction Z is different from the projection area of ​​the second fixing hole 102 along the first direction Z.

[0154] It should be noted that, on the projection plane perpendicular to the first direction Z, the projection of the first fixing hole 2001, the projection of the second fixing hole 102 and the projection of the first wall 210 are Figure 8 and Fig. 9 The projection of the first fixing hole 2001 along the first direction Z is the same as Figure 8 and Fig. 9 The schematic diagram of the first fixing hole 2001 along the first direction Z is the same as that of the second fixing hole 102 along the first direction Z. Figure 8 and Fig. 9 The projection of the second fixing hole 102 in the first wall 210 along the first direction Z is the same.

[0155] By adopting the above technical solution, the first connector 10 can float relative to the first device 200, so that the second fixing hole 102 floats relative to the first fixing hole 2001; and the first fixing hole 2001 and the second fixing hole 102 can be maintained in a relative state, so that the first fixing hole 2001 and the second fixing hole 102 can be fixed by fasteners, thereby realizing the assembly of the first connector 10 on the first device 200. In this way, the manufacturing error of at least one of the first connector 10, the second connector 20, the first device 200 and the second device 300 along the plane intersecting the first direction Z can be offset to a certain extent.

[0156] For example, during the assembly of the power device 1000, the first connector 10 and the second connector 20 can be plugged and matched. Then, the first connector 10 is floated relative to the first device 200, so that the second fixing hole 102 floats relative to the first fixing hole 2001, and is fixed to the first fixing hole 2001 by a fastener, thereby achieving the assembly of the first connector 10 on the first device 200.

[0157] In some embodiments, please refer to Figure 5 and Figure 8 On the projection plane perpendicular to the first direction Z, the aperture of the projection of the first fixing hole 2001 along the second direction X1 is different from the aperture of the projection of the second fixing hole 102 along the second direction X1, and the second direction X1 intersects the first direction Z.

[0158] It can be understood that the aperture of the first fixing hole 2001 along the first direction Z projected onto the second direction X1 is different from the aperture of the second fixing hole 102 along the first direction Z projected onto the second direction X1.

[0159] In this way, the first connector 10 can float relative to the first device 200 along the second direction X1, so that the second fixing hole 102 floats relative to the first fixing hole 2001; and the first fixing hole 2001 and the second fixing hole 102 can be maintained in a relative state, so that the first fixing hole 2001 and the second fixing hole 102 can be fixed by fasteners to achieve the assembly of the first connector 10 on the first device 200. In this way, the manufacturing error of at least one of the first connector 10, the second connector 20, the first device 200 and the second device 300 in the second direction X1 can be offset to a certain extent.

[0160] Based on this, in the process of assembling the power device 1000, the first connector 10 and the second connector 20 can be plugged and matched first. Then, the first connector 10 is floated relative to the first device 200 along the second direction X1, so that the second fixing hole 102 is floated relative to the first fixing hole 2001 along the second direction X1, and is fixed to the first fixing hole 2001 by a fastener, so as to realize the assembly of the first connector 10 on the first device 200. In addition, the second connector 20 is assembled on the second device 300. Among them, the assembly of the second connector 20 on the second device 300 can also be before the assembly groove of the first connector 10 on the first device 200.

[0161] In some other embodiments, see Fig. 9, and combined with other drawings. On the projection plane perpendicular to the first direction Z, the aperture of the projection of the first fixing hole 2001 along the second direction X1 is different from the aperture of the projection of the second fixing hole 102 along the second direction X1, and the aperture of the projection of the first fixing hole 2001 along the third direction Y1 is different from the aperture of the projection of the second fixing hole 102 along the third direction Y1, the first direction Z intersects with the second direction X1, the first direction Z intersects with the third direction Y1, and the second direction X1 intersects with the third direction Y1.

[0162] It can be understood that the aperture of the first fixing hole 2001 projected along the first direction Z onto the second direction X1 is different from the aperture of the second fixing hole 102 projected along the first direction Z onto the second direction X1. In addition, the aperture of the first fixing hole 2001 projected along the first direction Z onto the third direction Y1 is different from the aperture of the second fixing hole 102 projected along the first direction Z onto the third direction Y1.

[0163] In this way, the first connector 10 can float relative to the first device 200 in the second direction X1 and the third direction Y1, respectively, so that the second fixing hole 102 can float relative to the first fixing hole 2001 in the second direction X1 and the third direction Y1, respectively; and the first fixing hole 2001 and the second fixing hole 102 can be maintained in a relative state, so that the first fixing hole 2001 and the second fixing hole 102 can be fixed by fasteners to achieve the assembly of the first connector 10 on the first device 200. In this way, the manufacturing error of at least one of the first connector 10, the second connector 20, the first device 200 and the second device 300 in the second direction X1 and the third direction Y1 can be offset to a certain extent.

[0164] Based on this, in the process of assembling the power device 1000, the first connector 10 and the second connector 20 can be plugged and matched first. Then, the first connector 10 is floated relative to the first device 200 along the second direction X1 and the third direction Y1, so that the second fixing hole 102 is floated relative to the first fixing hole 2001 along the second direction X1 and the third direction Y1, and is fixed to the first fixing hole 2001 by a fastener, so as to realize the assembly of the first connector 10 on the first device 200. In addition, the second connector 20 is assembled on the second device 300. Among them, the assembly of the second connector 20 on the second device 300 can also be before the assembly groove of the first connector 10 on the first device 200.

[0165] It should be supplemented here that the intersection of the first direction Z and the second direction X1 means that the first direction Z and the second direction X1 can form an angle greater than 0° and less than 180°, that is, the first direction Z and the second direction X1 are not parallel. Among them, the first direction Z and the second direction X1 can be perpendicular to each other, or they can be non-perpendicular. The first direction Z and the second direction X1 can be directions that intersect on the same plane, or they can be directions on planes that are not on the same plane, and the projection of the second direction X1 on the plane where the first direction Z is located can intersect with the first direction Z. The intersection of the first direction Z and the third direction Y1, and the intersection of the second direction X1 and the third direction Y1 can also be explained in the same way, which will not be elaborated here.

[0166] As an example, the second direction X1 is parallel to the X1 axis, and the third direction Y1 is parallel to the Y1 axis. In other examples, the second direction X1 may also intersect the X1 axis, and the third direction Y1 may also intersect the Y1 axis.

[0167] In some embodiments, please refer to Fig.10 and Fig.11 , and combined with other drawings. Among them, Fig.10 A partial top view of a second wall 330 of a second device 300 of an electric power device 1000 provided in some embodiments of the present application, Fig.11 Partial top view of the second wall 330 of the second device 300 of the power device 1000 provided in some other embodiments of the present application. The two partial top views of the second wall 330 are schematic diagrams of the second wall 330 along the first direction Z, and both schematic diagrams use dotted lines to illustrate the projection outline of the fourth fixing hole 202 projected onto the second wall 330 along the first direction Z. The second device 300 is provided with a third fixing hole 3001, and the second connector 20 is provided with a fourth fixing hole 202, and the fourth fixing hole 202 is used to cooperate with the third fixing hole 3001 for fixing. On the projection plane perpendicular to the first direction Z, the projection area of ​​the third fixing hole 3001 is different from the projection area of ​​the fourth fixing hole 202.

[0168] The fourth fixing hole 202 is used for cooperating and fixing with the third fixing hole 3001, which means that the fourth fixing hole 202 is used to be fixed to the third fixing hole 3001 by fasteners such as bolts and screws to achieve relative fixation of the third fixing hole 3001 and the fourth fixing hole 202. The fasteners are inserted into the third fixing hole 3001 and the fourth fixing hole 202 to achieve cooperating and fixing of the third fixing hole 3001 and the fourth fixing hole 202, so that the second connector 20 is assembled on the second device 300.

[0169] The third fixing hole 3001 and the fourth fixing hole 202 are arranged relatively to each other along the first direction Z, that is, the projection of the third fixing hole 3001 along the first direction Z and the projection of the fourth fixing hole 202 along the first direction Z are at least partially overlapped, so that the fastener can pass through the third fixing hole 3001 and the fourth fixing hole 202 along the first direction Z to fix the third fixing hole 3001 and the fourth fixing hole 202.

[0170] The projection area of ​​the third fixing hole 3001 along the first direction Z is different from the projection area of ​​the fourth fixing hole 202 along the first direction Z.

[0171] It should be noted that, on the projection plane perpendicular to the first direction Z, the projection of the third fixing hole 3001, the projection of the fourth fixing hole 202 and the projection of the second wall 330 are Fig.10 and Fig.11 The projection of the third fixing hole 3001 along the first direction Z is the same as Fig.10 and Fig.11 The schematic diagram of the third fixing hole 3001 along the first direction Z is the same as that of the fourth fixing hole 202 along the first direction Z. Fig.10 and Fig.11 The projection of the fourth fixing hole 202 in the second wall 330 along the first direction Z is the same.

[0172] By adopting the above technical solution, the second connector 20 can float relative to the second device 300, so that the fourth fixing hole 202 floats relative to the third fixing hole 3001; and the third fixing hole 3001 and the fourth fixing hole 202 can be maintained in a relative state, so that the third fixing hole 3001 and the fourth fixing hole 202 can be fixed by fasteners, thereby realizing the assembly of the second connector 20 on the second device 300. In this way, the manufacturing error of at least one of the first connector 10, the second connector 20, the first device 200 and the second device 300 along the plane intersecting the first direction Z can be offset to a certain extent.

[0173] For example, during the assembly of the power device 1000, the first connector 10 and the second connector 20 may be plugged and matched. Then, the second connector 20 is floated relative to the second device 300, so that the fourth fixing hole 202 floats relative to the third fixing hole 3001, and is fixed to the third fixing hole 3001 by a fastener, thereby assembling the second connector 20 on the second device 300.

[0174] In some embodiments, see Fig.10On the projection plane perpendicular to the first direction Z, the aperture of the projection of the third fixing hole 3001 along the fourth direction X2 is different from the aperture of the projection of the fourth fixing hole 202 along the fourth direction X2, and the fourth direction X2 intersects the first direction Z.

[0175] It can be understood that the aperture of the third fixing hole 3001 along the first direction Z projected onto the fourth direction X2 is different from the aperture of the fourth fixing hole 202 along the first direction Z projected onto the fourth direction X2.

[0176] In this way, the second connector 20 can float relative to the second device 300 along the fourth direction X2, so that the fourth fixing hole 202 floats relative to the third fixing hole 3001; and the third fixing hole 3001 and the fourth fixing hole 202 can be maintained in a relative state, so that the third fixing hole 3001 and the fourth fixing hole 202 can be fixed by fasteners, thereby realizing the assembly of the second connector 20 on the second device 300. In this way, the manufacturing error of at least one of the first connector 10, the second connector 20, the first device 200 and the second device 300 in the fourth direction X2 can be offset to a certain extent.

[0177] Based on this, in the process of assembling the power device 1000, the first connector 10 and the second connector 20 can be plugged and matched first. Then, the second connector 20 is floated relative to the second device 300 along the fourth direction X2, so that the fourth fixing hole 202 floats relative to the third fixing hole 3001 along the fourth direction X2, and is fixed to the third fixing hole 3001 by a fastener, so as to realize the assembly of the second connector 20 on the second device 300. In addition, the first connector 10 is assembled on the first device 200. The assembly of the first connector 10 on the first device 200 can also be before the assembly groove of the second connector 20 on the second device 300.

[0178] In some other embodiments, see Fig.11 , and combined with other drawings. On the projection plane perpendicular to the first direction Z, the aperture of the projection of the third fixing hole 3001 along the fourth direction X2 is different from the aperture of the projection of the fourth fixing hole 202 along the fourth direction X2, and the aperture of the projection of the third fixing hole 3001 along the fifth direction Y2 is different from the aperture of the projection of the fourth fixing hole 202 along the fifth direction Y2, the first direction Z intersects with the fourth direction X2, the first direction Z intersects with the fifth direction Y2, and the fourth direction X2 intersects with the fifth direction Y2.

[0179] It can be understood that the aperture of the third fixing hole 3001 projected along the first direction Z on the fourth direction X2 is different from the aperture of the fourth fixing hole 202 projected along the first direction Z on the fourth direction X2. In addition, the aperture of the third fixing hole 3001 projected along the first direction Z on the fifth direction Y2 is different from the aperture of the fourth fixing hole 202 projected along the first direction Z on the fifth direction Y2.

[0180] In this way, the second connector 20 can float in the fourth direction X2 and the fifth direction Y2 relative to the second device 300, so that the fourth fixing hole 202 can float in the fourth direction X2 and the fifth direction Y2 relative to the third fixing hole 3001; and the third fixing hole 3001 and the fourth fixing hole 202 can be maintained in a relative state, so that the third fixing hole 3001 and the fourth fixing hole 202 can be fixed by fasteners to achieve the assembly of the second connector 20 on the second device 300. In this way, the manufacturing error of at least one of the first connector 10, the second connector 20, the first device 200 and the second device 300 in the fourth direction X2 and the fifth direction Y2 can be offset to a certain extent.

[0181] Based on this, in the process of assembling the power device 1000, the first connector 10 and the second connector 20 can be plugged and matched first. Then, the second connector 20 is floated relative to the second device 300 along the fourth direction X2 and the fifth direction Y2, so that the fourth fixing hole 202 is floated relative to the third fixing hole 3001 along the fourth direction X2 and the fifth direction Y2, and is fixed to the third fixing hole 3001 by a fastener, so as to realize the assembly of the second connector 20 on the second device 300. In addition, the first connector 10 is assembled on the first device 200. Among them, the assembly of the first connector 10 on the first device 200 can also be before the assembly groove of the second connector 20 on the second device 300.

[0182] It should be noted that the meanings of the intersection of the fourth direction X2 and the first direction Z, the intersection of the fifth direction Y2 and the first direction Z, and the intersection of the fourth direction X2 and the fifth direction Y2 can also be referred to the explanation of the intersection of the first direction Z and the second direction X1, and will not be repeated here.

[0183] As an example, the fourth direction X2 is parallel to the X2 axis, and the fifth direction Y2 is parallel to the Y2 axis. In other examples, the fourth direction X2 may also intersect the X2 axis, and the fifth direction Y2 may also intersect the Y2 axis.

[0184] As an example, the fourth direction X2 is parallel to the second direction X1, and the fifth direction Y2 is parallel to the third direction Y1. In other examples, the fourth direction X2 may be parallel to the third direction Y1, and may intersect with the second direction X1 and the third direction Y1. The fifth direction Y2 may be parallel to the second direction X1, and may intersect with the second direction X1 and the third direction Y1.

[0185] As an example, the X2 axis is parallel to the X1 axis, and the Y2 axis is parallel to the Y1 axis. In other examples, the X2 axis may be parallel to the Y1 axis, or may intersect the X1 axis and the Y1 axis. The Y2 axis may be parallel to the X1 axis, or may intersect the X1 axis and the Y1 axis.

[0195] It should be supplemented here that the first wall 210 of the first device 200 and the second wall 330 of the second device 300 are distributed in sequence along the first direction Z. In addition, the side of the first wall 210 away from the second device 300 along the first direction Z refers to the side of the first wall 210 away from the second wall 330 along the first direction Z.
