[0001] This application is a divisional application. The application number of the original application is 202320763823.4, and the original application date is April 3, 2023. The entire contents of the original application are incorporated into this application by reference. Technical Field

[0002] The utility model relates to the technical field of electric vehicle charging, in particular to a connector and a charging device. Background Art

[0003] In the field of low-voltage power distribution, the charging host generally adopts the structure of a low-voltage drawer-type switch cabinet. Each distribution circuit adopts a modular design, and one drawer is configured as a distribution circuit. In this case, the plug is installed on the drawer circuit and the socket is installed on the cabinet body. The plug and socket of the connector can be connected and disconnected by plugging and unplugging the drawer.

[0004] The inside of the drawer of the power distribution circuit is generally connected to the plug part by cables or copper bars, while the socket outside the power distribution circuit is connected to the outside through cables. This design not only makes the product bulky and cannot meet the needs of miniaturization of product modules, but also, because the socket is a cable connection structure, it will also cause the connector to be unable to be directly connected to the device on the circuit board, resulting in poor reliability in use.

The connector can be connected to the plug board through the first connection portion, and connected to the charging module through the second connection portion. The second connection portion includes a first connection plate and a second connection plate, and the first connection plate is arranged perpendicular to the second connection plate so that the second connection portion is L-shaped. The first connection portion includes a clamping assembly, one end of the clamping assembly is used to plug into the plug board, and the other end clamps the first connection plate, and the second connection plate is used to plug into the charging module. Multiple connection assemblies are arranged along the second direction, and the second direction is perpendicular to the first direction.

[0007] The connector provided by the utility model is provided with a first connection part and a second connection part, the first connection part is plugged into the plug board, and the second connection part is plugged into the charging module. The second connection part is an L-shaped structure, and includes a first connection part and a second connection part. The first connection plate is used to connect with the first connection part, and the second connection plate is used to plug into the charging module. The first connection part is a clamping structure, which can stably clamp the first connection plate, thereby ensuring the connection effect of the connector. Since the plug-in method of the second connection plate and the charging module is different from the existing cable connection method, when the second connection plate is plugged into the charging module, it can be directly connected to the device on the circuit board of the charging module, thereby shortening the path of power transmission, and is conducive to reducing the volume of the product and improving the reliability of use.

[0008] In some possible embodiments, the clamping assembly may include a first clamping group and a second clamping group, the first clamping group and the second clamping group are arranged along a third direction, the third direction is perpendicular to the first direction and perpendicular to the second direction. The first clamping group includes two first clamping blocks arranged along the second direction, and the two first clamping blocks cooperate to clamp the first connecting plate. The second clamping group includes two second clamping blocks arranged along the second direction, and the two second clamping blocks cooperate to clamp the first connecting plate. The first clamping group and the second clamping group can respectively clamp different parts of the first connecting plate, so that the connection between the first connecting plate and the first connecting portion is more stable.

[0009] In some possible implementations, a plurality of insulating shells are further provided inside the housing, and the plurality of insulating shells correspond one to one to the plurality of connecting components. A channel is provided inside each insulating shell that passes through along the first direction, and the clamping component is inserted into the channel. By providing the insulating shells, two adjacent first connecting parts can be separated, so as to avoid the two first connecting parts contacting each other and causing damage to the performance of the connector.

[0010] In some possible implementations, a limiting portion may be provided inside the insulating housing, and the limiting portion may be used to limit the position of the clamping assembly.

The first connecting block may enter the insulating shell through the limiting channel to facilitate connection with the clamping assembly. When the first connecting plate is located in the limiting channel, the limiting channel may limit the first connecting plate, thereby preventing the position of the first connecting plate from changing significantly and failing to maintain connection with the first connecting portion.

[0014] In some possible implementations, the first limiting portion is provided with a limiting plate, which is arranged parallel to the first connecting plate, and when the first connecting plate is connected to the first connecting plate, the first connecting plate and the limiting plate remain in abutment with each other. The limiting plate can support and position the first connecting plate, thereby better maintaining the performance of the connector.

[0015] In some possible implementations, a circular pin shaft may be further provided in the limiting channel, and the first connecting plate may be provided with a first connecting hole. When the first connecting plate is located in the limiting channel, the circular pin shaft is located in the first connecting hole. The circular pin hole is a structure protruding from the inner wall of the limiting channel. When the circular pin hole is located in the first connecting hole, the first connecting plate may be further limited.

[0016] In some possible embodiments, the diameter of the first connecting hole is larger than the diameter of the circular pin. Specifically, the diameter of the first connecting hole may be slightly larger than the diameter of the circular pin, so that the first connecting plate can move relative to the clamping assembly in the first direction. And / or, the size of the limiting channel along the second direction is slightly larger than the size of the first connecting plate along the second direction, which can facilitate the movement of the first connecting plate in the second direction. And / or, the size of the limiting channel along the third direction is slightly larger than the size of the first connecting plate along the third reverse direction, so that the first connecting plate can move in the third direction, thereby enabling the first connecting plate to have the ability of soft connection. In addition, the gap between the circular pin and the inner wall of the limiting channel is smaller than the size of the first connecting plate along the second direction, which can further prevent the first connecting plate from detaching from the limiting channel.

[0017] In some possible implementations, a plug is provided between the insulating shell and the outer shell. The outer shell is provided with an opening, and the plug can extend into the inner part of the outer shell through the opening and abut against the surface of the insulating shell to keep the insulating shell and the outer shell fixed. In addition, the plug is clamped with the opening to keep the plug fixed to the outer shell, thereby further keeping the insulating shell and the outer shell fixed.

[0018] In some possible implementations, the side wall of the plug is provided with a plurality of protrusions, and the side wall of the opening is provided with grooves corresponding to the plurality of protrusions one by one, and each protrusion is snapped into the corresponding groove, so that the plug and the shell can be kept fixed.

[0019] In some possible implementations, the second connection plate is provided with a second connection hole, and a rivet nut is provided in the second connection hole. The second connection plate can be connected to the charged component in the charging module through the rivet nut, for example, the charged component can be connected to the rivet nut by screws, so as to shorten the path of power transmission.

[0036] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be used as limitations on the present invention. As used in the specification and appended claims of the present invention, the singular expressions "a", "an", "said", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context.

[0037] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the utility model include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0038] With the continuous development of electric vehicles, charging technology is also developing. As an important part of charging, charging pile products are developing towards high power, integration and modularization. For this, connectors are very suitable for the plug-in design of modular products. In the field of low-voltage power distribution, the charging host generally adopts the structure of a low-voltage drawer-type switch cabinet. Each distribution circuit adopts a modular design, and one drawer is configured as a distribution circuit. In this case, the plug is installed on the drawer circuit and the socket is installed on the cabinet body. The plug and socket of the connector can be connected and disconnected by plugging and unplugging the drawer.

[0039] The inside of the drawer of the power distribution circuit is generally connected to the plug part by cables or copper bars, while the socket outside the power distribution circuit is connected to the outside through cables. This design not only makes the product bulky and cannot meet the needs of miniaturization of product modules, but also, because the socket is a cable connection structure, it will also cause the connector to be unable to be directly connected to the device on the circuit board, resulting in poor reliability in use. In addition, the connection plate and the plastic shell body are tightly matched, resulting in the connection plate not having soft connection capabilities.

[0040] Based on this, the embodiment of the utility model provides a connector and a charging system, which can not only realize the miniaturization design of the product, but also can be directly connected to the components on the circuit board, shorten the power transmission path, and the connecting board has a soft connection capability. The above connector and charging system are described in detail below in conjunction with specific embodiments.

[0041] refer to Figure 1 , Figure 1 1 is a schematic diagram of a charging system in an embodiment of the present utility model. The charging system in the embodiment of the present utility model may include a charging host 1 and a charging device 2. The charging host 1 includes a plug board 13, a connector 11 and a plurality of charging modules 12. Figure 1As shown, the multiple charging modules 12 include charging module 12-1, charging module 12-2, charging module 12-3 and charging module 12-4. The multiple charging modules 12 are connected to the plug board 13 through the connector 11. The multiple charging modules 12 may include an AC-DC conversion module and a DC-DC conversion module. For example Figure 1 In the embodiment, the charging modules 12-1 and 12-2 may be AC-DC modules, and the charging modules 12-3 and 12-4 may be DC-DC modules. Of course, the multiple charging modules 12 (charging module 12-1, charging module 12-2, charging module 12-3 and charging module 12-4) may be charging modules that integrate AC-DC modules and DC-DC modules.

[0042] Exemplarily, the charging modules 12-1 and 12-2 are AC-DC modules, and the charging modules 12-3 and 12-4 are DC-DC modules. The charging modules 12-1 and 12-2 can be connected to the AC input source 3. The charging modules 12-1 and 12-2 rectify the AC power output by the AC input source 3 and convert it into DC power, and then transmit the DC power to the charging modules 12-3 and 12-4 through the connector and the plug board. The charging modules 12-3 and 12-4 convert the voltage of the input DC power and output it to the charging device 2.

[0043] The charging device 2 is installed in a public building, such as an office building, a shopping mall, a public parking lot, etc., or can also be installed in a residential parking lot or a charging station, for charging various types of electric vehicles. The charging device 2 includes a charging pile 201 and a charging gun 202. The charging pile 201 is used to receive the DC power transmitted by the charging host 1, and the charging pile 201 provides DC power to the charging gun 202, so that the user can charge the vehicle through the charging gun 202.

[0044] In this embodiment, reference Figure 2 , Figure 2It is a structural schematic diagram of the connection between the charging module 12 and the plug board 13 in the charging host 1 in the embodiment of the utility model. When the charging module 12 is connected to the plug board 13, the connection can be made through the connector 11. For example, one side of the plug board 13 is provided with multiple pairs of connection ports 201, and each charging module 12 can be connected to a pair of connection ports 201 through a pair of connectors 11. Specifically, a copper bus is provided in each connection port 201 of the plug board 13, and a part of the connector 11 is located outside the charging module 12, and is plugged with the connection port 201 through this part. Another part of the connector 11 is located inside the charging module 12, and is connected to the electronic components inside the charging module 12, such as a circuit board, to achieve electrical connection between the plug board 13 and the charging module 12.

[0045] Exemplarily, after the plug board 13 transmits the AC power output by the AC input source 3 to the charging module 12-1 or the charging module 12-2 through one of the connectors 11, the conversion unit inside the charging module 12-1 or the charging module 12-2 converts the AC power into DC power, and then transmits the DC power to the DC-DC module on the plug board 13 through another connector 10.

[0046] refer to Figure 3 and Figure 4 , Figure 3 This is a schematic diagram of the overall structure of the connector in the embodiment of the utility model. Figure 4 for Figure 3 Schematic diagram of the internal structure of the connector. The connector 11 in this embodiment may include a housing 32, a plurality of connection components 31, and an insulating shell 41 corresponding to the plurality of connection components 31. The insulating shell 41 is located inside the housing 32, and a portion of the connection component 31 is located inside the housing 32. Each connection component 31 includes a first connection portion 42 and a second connection portion 43. The first connection portion 42 and the second connection portion 43 are respectively located on both sides of the housing 32 along the first direction. For example, the first connection portion 42 can be used to connect to the housing 32. Figure 2 The second connection portion 43 can be connected to the connection port 201 of the plug board 13 as shown. Figure 2 The electronic components in the charging module 12 are connected, and the first direction here can be understood as the transmission direction of the electric energy in the connector 11. In addition, the plurality of connecting components 31 are arranged along the second direction, which can be regarded as the width of the housing 32, and the second direction is perpendicular to the first direction.

[0047] The insulating housing 41 is provided with a passage (not shown) penetrating along the first direction, and the first connection portion 42 can be inserted into the insulating housing 41. The insulating housing 41 can separate adjacent first connection portions 42 to prevent adjacent first connection portions 41 from contacting and affecting the connection effect of the connector 11. The first connection portion 42 includes a clamping assembly, which includes a first clamping group 44 and a second clamping group 45. The first clamping group 44 and the second clamping group 45 are arranged along a third direction, which can be understood as the height direction of the housing 32, and the third direction is perpendicular to the first direction and the second direction.

[0048] For reference Figure 3 , Figure 4 and Figure 5 , Figure 5 for Figure 4 The schematic diagram of the structure of the first clamping group is as follows: the first clamping group 44 comprises two first clamping blocks 4401, and the two first clamping blocks 4401 are arranged along the second direction. The middle parts of the two first clamping blocks 4401 are connected by a first damping member 4402. The first damping member 4402 can make the two ends of the two first clamping blocks 4401 maintain a certain opening respectively, and the opening of one end of the two first clamping blocks 4401 close to the second connecting part 43 is smaller. When the two first clamping blocks 4401 clamp the second connecting part 43, the two first clamping blocks 4401 can clamp the second connecting part 43 tightly due to the smaller opening of this end. In addition, the housing 32 is also provided with a plug-in port 33 corresponding to the first connecting portion 42. One end of the first clamping block 4401 is arranged close to the plug-in port 33. The opening formed by the two first clamping blocks 4401 can be matched with a suitable copper bus or a male connector through the plug-in port 33. For example, the two first clamping blocks 4401 cooperate to clamp the copper bus, thereby realizing the connection between the connector 11 and the plug board 13.

[0049] Similarly, the second clamping group 45 includes two second clamping blocks (not shown in the figure, refer to Figure 5 The structure of the first clamping group 44 in the middle, the two second clamping blocks are arranged along the second direction, and the middle parts of the two second clamping blocks are connected by the second damping member, so that the two ends of the two second clamping blocks respectively maintain a certain opening, and the opening of the end of the two second clamping blocks close to the second connecting part 43 is smaller. When the two second clamping blocks clamp the second connecting part 43, the opening of this end is smaller, so that the two second clamping blocks can clamp the second connecting part. The two second clamping blocks are also arranged opposite to the plug-in port 33, and the opening formed by the two second clamping blocks can cooperate with the first clamping group 44 and connect to the copper bus or the male connector, thereby ensuring the stability of the connection.

[0050] Continue to refer Figure 4, the second connection part 43 includes a first connection plate 431 and a second connection plate 432, the first connection plate 431 and the second connection plate 432 are perpendicular to each other, and the first connection plate 431 is placed vertically, and the second connection plate 432 is placed horizontally. One end of the first connection plate 431 can be clamped by the first clamping group 44 and the second clamping group 45, so that the first connection plate 431 is connected to the second connection part 43. Exemplarily, the first clamping group 44 can clamp the upper end of the first connection plate 431, and the second clamping group 45 can connect the lower end of the first connection plate 431, so as to ensure the connection effect between the first connection part 42 and the second connection part 43. The second connection plate 432 is connected to the side of the first connection plate 431 away from the first connection part 42, and the second connection plate 432 is used for connection with other modules.

[0051] It should be understood that the clamping groups in the embodiment of the utility model are not limited to two, and in practical applications, can also be one or more, such as three, four, etc. Moreover, in this embodiment, the flow capacity of the connector can be adjusted by adjusting the number of clamping groups, thereby adjusting the rated flow capacity of the product.

[0052] In addition, the number of connection components 31 in a connector 11 can also be designed according to actual needs, such as Figure 4 As shown in the figure, there are two connection components 31. In some other embodiments, there may be multiple connection components 31, such as three, four, etc. It should be understood that by adjusting the number of connection components 31, the number of power paths of the connector 11 can be adjusted. The more the number of connection components 31, the more the number of power paths of the connector 11.

[0053] refer to Figure 6 and Figure 7 , Figure 6 for Figure 4 A schematic diagram of an exploded structure inside the connector. Figure 7 for Figure 4 Another exploded structural diagram of the inside of the connector. The insulating shell 32 includes a first insulating shell 321 and a second insulating shell 322. The first insulating shell 321 and the second insulating shell 322 are snap-fitted to form a channel for accommodating the first connecting portion 42. Specifically, the first insulating shell 321 and the second insulating shell 322 are both square shells with an opening at one end. A snap-fit ​​groove 3211 is provided on the side of the first insulating shell 321 facing the second insulating shell 322, and a snap-fit ​​block 3221 is provided on the side of the second insulating shell 322 facing the first insulating shell 321. When the first insulating shell 321 and the second insulating shell 322 are spliced, the snap-fit ​​block 3221 is snap-fitted into the snap-fit ​​groove 3211, so that the first insulating shell 321 and the second insulating shell 322 are relatively fixed.

[0054] A limiting portion is provided in the insulating housing 41, and the limiting portion can be used to limit the first clamping group 44 and the second clamping group 45, so that each clamping assembly can remain stable to ensure the connection effect of the connector. Specifically, the limiting portion is provided in a portion of the insulating housing 41 away from the second connecting portion 43, and the limiting portion includes limiting grooves 330 corresponding to the number of clamping groups. For example, in this embodiment, the first clamping group 44 and the second clamping group 45 are provided, and then there are two limiting grooves 330. Each limiting groove 330 may include a pair of first limiting blocks 3301 and a pair of second limiting blocks 3302, and the two first limiting blocks 3301 in the pair of first limiting blocks 3301 are respectively arranged on the side walls of the first insulating shell 321 and the second insulating shell 322, and the two second limiting blocks 3302 in the pair of second limiting blocks 3302 are respectively arranged on the side walls of the first insulating shell 321 and the second insulating shell 322, and a certain space is formed between the first limiting block 3301 and the second limiting block 3302, and the first clamping group 44 is clamped in the limiting groove 330, that is, the two side surfaces of the first clamping group 44 along the third direction are respectively abutted against the first limiting block 3301 and the second limiting block 3302.

[0055] In this embodiment, a limit block can be shared between two adjacent limit slots 330. For example, when three limit blocks are set, the middle limit block can cooperate with the upper limit block to form the limit slot 330, and can also cooperate with the lower limit block to form the limit slot 330.

[0056] refer to Figures 8 to 11 , Figure 8 This is a schematic diagram of the structure of the insulating housing in the embodiment of the utility model. Fig. 9 for Figure 8 A schematic diagram of a structure in which the middle insulating shell is connected to the second connecting part, Fig.10 for Fig. 9 A schematic cross-sectional structure diagram of the connection between the middle insulating shell and the second connecting part, Fig.11 for Fig. 9 Another cross-sectional structural schematic diagram of the connection between the insulating shell and the second connecting portion. A limiting assembly is also provided on one side of the insulating shell 41 close to the second connecting portion 43, and the limiting assembly can be used to limit the first connecting plate 431. Specifically, the limiting assembly may include a first limiting portion 340 provided at the end of the first insulating shell 321 and a second limiting portion 350 provided at the end of the second insulating shell 322. When the first insulating shell 321 and the second insulating shell 322 are engaged, the first limiting portion 340 is engaged with the second limiting portion 350, and a limiting channel 360 extending along the first direction is formed. The first connecting plate 431 can enter the insulating shell 41 from the outside of the insulating shell 41 through the limiting channel 360 and be clamped by the clamping assembly.

[0057] Combination Figure 6 , Figure 7, Figure 8 and Fig.12 , Fig.12 It is a structural schematic diagram of the second connection part in the embodiment of the utility model. A circular pin shaft 370 is provided in the limiting channel 360, and the circular pin shaft 370 may include a first protrusion 371 provided on the first limiting part 340 and a second protrusion 372 provided on the second limiting part 350. When the first limiting part 340 and the second limiting part 350 are engaged, the first protrusion 371 and the second protrusion 372 cooperate to form the circular pin shaft 370. Correspondingly, a first connection hole 2211 is provided on the first connection plate 431. When the first connection plate 431 passes through the limiting channel 360, the circular pin shaft 370 is located in the first connection hole 2211 to limit the movement of the first connection plate 431 relative to the insulating shell 41.

[0058] In this embodiment, the size of the limiting channel 360 may be slightly larger than the size of the first connecting plate 431, so that the first connecting plate 431 can move up and down, left and right, and front and back within a certain range in the limiting channel 360, so that the first connecting plate 431 has a soft connection capability. Specifically, the size of the limiting channel 360 along the second direction is slightly larger than the size of the first connecting plate 431 along the second direction, which can make the first connecting plate 431 move along the second direction. The size of the limiting channel 360 along the third direction is also slightly larger than the size of the first connecting plate 431 along the third direction, which can make the first connection move along the third direction. In addition, the diameter of the first connecting hole 2211 may also be slightly larger than the diameter of the circular pin 370, which can make the first connecting plate connecting plate move along the first direction. Thus, the first connecting plate 431 can move relative to the insulating housing 41 in the first range along the first direction, the second direction, and the third direction, so that the first connecting plate 431 has a soft connection capability.

[0059] On this basis, in order to prevent the first connecting plate 431 from escaping from the limiting channel 360, as an implementation method, the gap between the circular pin shaft 370 and the limiting channel 360 can be made smaller than the size of the first connecting plate 431 along the second direction. In this way, even if the first connecting plate 431 moves along the second direction, it cannot be separated from the state where the circular pin shaft 370 is clamped in the first connecting hole 2211.

[0060] refer to Figure 8 The first limiting portion 340 is provided with a limiting plate 341, and the limiting plate 341 is parallel to the first connecting plate 431. When the first connecting plate 431 is clamped by the clamping assembly, the first connecting plate 431 can be tightly attached to the limiting plate 341, thereby further limiting the first connecting plate 431 and preventing the first connecting plate 431 from deformation.
