Description

Technical Field

[0001] The present application relates to the field of charging piles, and in particular to high-current connector plugs, high-current connectors, and charging modules for charging piles. Background Art

[0002] With the development of charging technology, the charging modules of charging piles require increasingly larger charging power and charging current, which results in the pins used to connect the charging modules becoming thicker and thicker, and therefore the pinhole diameter becomes larger and larger.

[0003] However, the size of the charging pile is strictly limited, so the volume of the connector is also required to be as small as possible. In this case, the traditional straight-plug connection with the same direction of travel as the pin is no longer applicable because it takes up a lot of space.

[0004] To address this issue, traditional connectors use tools to bend the connector pins 90 degrees. However, as charging power increases and the connector pins become thicker, the pins no longer protrude far enough from the connector to support the 90-degree bend. This bending process can easily cause connector failure. Designing a new connector would require a complete overhaul of the traditional process. Summary of the Invention

[0005] Based on this, it is necessary to provide a high-current connector plug-in, a high-current connector and a charging module for a charging pile.

[0048] The present application discloses a high-current connector plug, a high-current connector, and a charging module for a charging pile, which include some or all of the technical features of the following embodiments; that is, the high-current connector plug, the high-current connector, and the charging module for a charging pile include some or all of the following structures. In one embodiment of the present application, a high-current connector plug is applied to a pin with a diameter greater than 8 mm, which includes a first pin and a second pin; the first pin includes a first pin body and a first assembly end that are connected, and the first pin body is configured to be set in a connecting socket; the second pin includes a second pin body and a second assembly end that are connected, and the second pin body is configured to be plugged into a target socket; the first assembly end is connected to the second assembly end and has a preset angle, so that the first pin is connected to the second pin and forms the preset angle. The above-mentioned high-current connector plug is suitable for pins with a diameter greater than 8 mm. Through the cooperation of the first pin and the second pin, on the one hand, it is conducive to ensuring that the first assembly end and the second assembly end are firmly connected, thereby effectively realizing the power transmission of the high-power charging module and solving the power transmission requirements of 60 kilowatts or more power modules; on the other hand, the first pin body and the second pin body are respectively connected to the current input end and the output end, so that the high-current connector plug is suitable for various high-power charging environments, especially suitable for use in charging piles; on the other hand, the first pin and the second pin form a preset angle, which ensures that the connection is safe and effective, so that the high-current connector plug occupies less space than the traditional connector, and there is no need to bend the pins, thereby avoiding the defect of the high-current connector plug due to bending the pins; on the other hand, it does not involve the change of the shape of the traditional connection seat, so there is no need to add an additional connection seat mold, nor to change the production process of the connection seat, which is conducive to the promotion and application of high-current connector plugs. The following is combined with Figures 1 to 9 , the high-current connector plug-in, high-current connector and charging module for charging pile are described in detail.

[0049] In some embodiments, a high current connector 100 is Figure 1 and Figure 2As shown, the high-current connector plug 100 is applied to pins with a diameter greater than 8 mm, and includes a first pin 110 and a second pin 120; the first pin 110 includes a first pin body 111 and a first assembly end 112 connected to each other, and the first pin body 111 is configured to be set in the connecting seat 200; the second pin 120 includes a second pin body 121 and a second assembly end 122 connected to each other, and the second pin body 121 is configured to be plugged into the target socket; the first assembly end 112 is connected to the second assembly end 122 and has a preset angle 130, so that the first pin 110 is connected to the second pin 120 and forms the preset angle 130. The high-current connector plug 100 is suitable for pins with a diameter greater than 8 mm. The first pin 110 and the second pin 120 cooperate with each other, which is conducive to ensuring that the first assembly end 112 and the second assembly end 122 are firmly connected, thereby effectively realizing the power transmission of the high-power charging module and solving the power transmission requirements of 60 kilowatts or more power modules; on the other hand, the first pin body 111 and the second pin body 121 are connected to the current input end and the output end respectively, making the high-current connector plug 100 suitable for various high-power charging environments, especially suitable for applications. Used for charging piles; on the other hand, the first pin 110 and the second pin 120 form a preset angle 130, which ensures safe and effective connection, so that the high-current connector plug 100 occupies less space than the traditional connector, and there is no need to bend the pins, thereby avoiding the high-current connector plug 100 from being defective due to bending the pins; on the other hand, it does not involve changing the shape of the traditional connecting socket 200, so there is no need to add an additional mold for the connecting socket 200, nor is there any need to change the production process of the connecting socket 200, which is conducive to the promotion and application of the high-current connector plug 100.

[0050] For a conventional charging module with a charging power of 40 kW, it is technically feasible to bend the pins by bending them 90 degrees using a tool. However, for charging modules with a charging power of 60 kW or higher, in order to meet the safety requirements of the charging current, the pin diameter needs to be 8 mm or higher. However, given the small size of the connector and the small margin of the pin extending out of the connector, large-diameter pins are difficult to bend and the connector is easily damaged during the bending process. In various embodiments, the high-current connector plug 100 is applied to pins with a diameter greater than 8 mm, so that it can be used in connectors with currents greater than 150A. This is larger than the current specifications of traditional connectors, and is therefore called a high-current connector plug 100. In specific applications, the high-current connector plug 100 can be safely used in connectors with currents greater than 200A. Moreover, when the pin diameter is larger, the high-current connector plug 100 can be applied to even larger current specifications. It is understandable that the pins include a first pin 110 and a second pin 120 , and the diameter of the pins can generally be understood as the diameter of the first pin body 111 and the second pin body 121 .

[0051] In each embodiment, the first pin 110 includes a first pin body 111 and a first assembly end 112 connected to each other, and the first pin body 111 is configured to be set in the connecting seat 200; the second pin 120 includes a second pin body 121 and a second assembly end 122 connected to each other, and the second pin body 121 is configured to be plugged into the target socket; the first assembly end 112 is connected to the second assembly end 122, thereby realizing a split-combination pin as the high-current connector plug 100, which is connected by combining two pin splits together without bending the pins, thereby avoiding malfunction of the high-current connector plug 100 due to bending the pins, and realizing a firm connection between the two pin splits, which can effectively ensure the power transmission of the pins.

[0052] In order to make the high current connector 100 adapt to various narrow space usage environments, in some embodiments, such as Figure 1 and Figure 2As shown, the first pin body 111 has a first axis 114, and the second pin body 121 has a second axis 124; when the first pin 110 and the second pin 120 are connected, the first axis 114 and the second axis 124 form the preset angle 130. For embodiments other than the illustrated shapes, the first pin 110 can also be referred to as a first extension line, that is, a straight line in the extension direction of the first pin body 111, and the second axis 124 can also be referred to as a second extension line, that is, a straight line in the extension direction of the second pin body 121. In some embodiments, the preset angle 130 is 70 degrees to 120 degrees; as an example, the preset angle 130 is 70 degrees, 80 degrees, 90 degrees, 100 degrees, 110 degrees, 115 degrees or 120 degrees, etc. Combined Figure 3 In some embodiments, the preset angle 130 is 90 degrees. The preset angle 130 of 90 degrees is suitable for more regular application environments and is also conducive to cooperating with the realization of conventional structural designs. Moreover, such a design, on the one hand, the setting of the preset angle 130 enables the high-current connector plug 100 to occupy less space than traditional connectors while ensuring safe and effective connection, and can better adapt to narrow spaces. The angle range of the preset angle 130 is 70 degrees to 120 degrees, and multiple angles such as 70 degrees, 80 degrees, and 90 degrees are optional, which provides flexible options for different application scenarios. Taking the preset angle 130 of 90 degrees as an example, it is suitable for more regular application environments and is also conducive to cooperating with the realization of conventional structural designs, thereby enhancing the applicability of the high-current connector plug 100 and the high-current connector 300 using the high-current connector plug 100 in conventional scenarios. Furthermore, this design eliminates the need for bending pins, thus preventing defects in the high-current connector 100 that could occur due to pin bending, thereby ensuring the performance and reliability of the high-current connector 100 and the high-current connector 300 that utilizes it. Furthermore, this design does not alter the shape of the conventional connector socket 200, does not require the addition of a mold for the connector socket 200, and does not require changes to the production process for the connector socket 200, thus facilitating the widespread application of the high-current connector 100.

[0053] The following example illustrates the specific design of the high-current connector 100. Taking the electric vehicle charging interface as an example, the national standard GB / T20234.3 recommends a 125A DC charging pin diameter of 6.0mm to 6.5mm, requiring copper and a semi-exposed design. Heat dissipation space must be reserved when adapting to 120A scenarios. However, with technological advancements, the current of 125A DC charging needs to be further increased. The national standard GB / T20234.3 recommends a 250A DC charging pin diameter of approximately 8.0mm to 8.5mm, also requiring copper and a semi-exposed design. With heat dissipation margin, the corresponding safety current is approximately 200A to 220A. Furthermore, in general safety scenarios, an 8mm diameter copper pin is suitable for currents of 150A to 200A, with 150A being preferred for high safety margins. This is suitable for insulated environments, high outdoor temperatures, or long-term full-load operation.

[0054] For the pins including the first pin 110 and the second pin 120, the diameter d=8mm, so the cross-sectional area S=πd 2 / 4=50.24mm 2 .

[0055] Since the safety current I=S×J, where the current carrying capacity density J is adjusted according to the scenario, high safety requirements need to be met in insulated and closed application environments.

[0056] Take the current carrying capacity density J as 3A / mm 2 , then the safety current I=50.24mm 2 ×3A / mm 2 =150.72A, rounded to 150A.

[0057] If the current carrying density J is 4A / mm 2 , then the safety current I=50.24mm 2 ×4A / mm 2 =200.96A, rounded to 200A.

[0058] Therefore, in order to meet the charging current of not less than 200A, the high-current connector plug 100 needs to use a pin with a diameter greater than 8 mm.

[0059] In order to facilitate the first pin 110 to be assembled in place in the connection seat 200, in some embodiments, such as Figure 2 and Figure 3As shown, the first pin 110 also includes a first protrusion 113 located between the first pin body 111 and the first assembly end 112. The first protrusion 113 is configured to abut against the connecting seat 200. It can also be understood that the first protrusion 113 is configured to abut against the connecting seat 200. As an example, the first protrusion 113 abuts against the connecting seat 200 in a snap-fit ​​manner or an interference fit manner. As an example, the first protrusion 113 is cylindrical or cylindrical in shape. With such a design, on the one hand, the first protrusion 113 is configured to abut against the connecting seat 200 in a snap-fit ​​or interference fit manner. This abutment structure can accurately locate the assembly position of the first pin 110 in the connecting seat 200, ensuring that the pin can be accurately installed in place, avoiding poor contact or connection failure problems caused by assembly deviation. For example, when the first protrusion 113 is abutted by snapping, quick assembly and secure locking can be achieved through the elastic deformation of the snap-fit ​​structure; if an interference fit is adopted, the tightness between the components can be used to prevent the pin from loosening in the connector 200, thereby effectively ensuring the reliability of the connection during high current transmission. On the other hand, the first protrusion 113 is designed to be cylindrical or cylindrical in shape. On the one hand, it is easy to process and manufacture, and can improve the precision of parts through standardized production processes, reducing processing difficulty and cost; on the other hand, this shape can form a more uniform force distribution with the corresponding cavity of the connector 200, thereby enhancing the structural stability after assembly. At the same time, this design does not involve changing the original shape of the connector 200, and does not require additional customized molds or adjustments to the production process. It retains the traditional manufacturing process of the connector 200, and improves the assembly convenience through the structural optimization of the first protrusion 113, which is conducive to the large-scale production and application promotion of the high-current connector plug 100.

[0060] In order to facilitate the assembly of the second pin 120 relative to the first pin 110, in some embodiments, as Figure 2 and Figure 3As shown, the second pin 120 also includes a second protrusion 123 located between the second pin body 121 and the second assembly end 122. When the first assembly end 112 is connected to the second assembly end 122, the second protrusion 123 is configured to abut the first assembly end 112. As an example, the second protrusion 123 is cylindrical or cylindrical in shape. With such a design, on the one hand, when the first assembly end 112 is connected to the second assembly end 122, the second protrusion 123 is configured to abut the first assembly end 112. This abutment structure can accurately locate the assembly position of the second pin 120 relative to the first pin 110, ensuring that the two can be accurately in place when connected, avoiding unreliable connection or poor contact problems caused by assembly deviation, thereby effectively ensuring the stability and reliability of the connection during high current transmission. Secondly, the cylindrical or cylindrical shape of second protrusion 123 facilitates manufacturing, improving part precision through standardized production processes and reducing manufacturing difficulty and costs. Furthermore, this shape creates a more uniform force distribution with first assembly end 112, enhancing structural stability after assembly and further strengthening the connection between second pin 120 and first pin 110. Furthermore, this design does not involve significant changes to the existing main structure of first and second pins 110, 120, requiring no additional custom molds or complex production processes. This design preserves the existing pin manufacturing process while improving assembly convenience through the optimized structure of second protrusion 123, facilitating large-scale production and widespread application of high-current connector 100.

[0061] In order to facilitate the conductive connection, in some embodiments, such as Figure 1 and Figure 2As shown, the first pin body 111 and the second pin body 121 both have a cylindrical shape or a cylindrical shape. As an example, the first pin body 111 and the second pin body 121 both have a cylindrical shape and the diameter of the cylindrical shape is greater than or equal to 8 mm. As an example, the first pin body 111 is configured to be arranged in the connecting seat 200 and to contact, for example, be plugged into, the current input end or the output end, and the second pin body 121 is configured to be plugged into the target socket. When the first pin body 111 contacts the current input end, the second pin body 121 is plugged into the current output end of the target socket; when the first pin body 111 contacts the current output end, the second pin body 121 is plugged into the current input end of the target socket. Such a design, on the one hand, improves the conductive performance. The cylindrical or cylindrical pin body has a regular geometric shape, which can form a large and uniform contact interface with the current input end, output end or target socket, reducing contact resistance and power loss, and ensuring the transmission stability of large currents such as power modules of 60 kilowatts and above. For example, when the first pin body 111 is plugged into the connector 200 and contacts the current input / output end, the cylindrical structure can achieve low-impedance conductivity through a tight fit; when the second pin body 121 is plugged into the target socket, the plug-in adaptability of the cylindrical surface is also used to ensure a reliable connection between the current output end and the input end, meeting the power transmission requirements of the high-power charging module. On the other hand, starting from the structural adaptability, the cylindrical or cylindrical shape is easy to manufacture in a standardized manner, and the dimensional accuracy of the pin body can be ensured through unified mold processing, adapting to the design requirements of pins with a diameter greater than 8 mm. This shape is highly compatible with the cavity structure of connector base 200 or the target socket, ensuring accurate positioning of the pin during installation while enhancing connection stability through interference fit or snap-fit, thereby preventing heat generation or malfunctions caused by poor contact. Furthermore, this design maintains the traditional production process for connector base 200 and eliminates the need for new molds, reducing production costs and promoting the application of high-current connector insert 100 in high-power charging environments such as charging piles.

[0062] In order to facilitate the production of the high current connector plug 100, Figure 1 and Figure 8As shown, in some embodiments, the first pin body 111 and the first assembly end 112 are integrally provided; or, in some embodiments, the second pin body 121 and the second assembly end 122 are integrally provided; or, in some embodiments, the first assembly end 112 and the second assembly end 122 are integrally provided; or, in some embodiments, the first pin 110 and the second pin 120 are integrally provided. With such a design, on the one hand, when the first pin body 111 and the first assembly end 112 are integrally provided, the manufacturing can be completed through a one-time molding process such as stamping or die-casting, thereby avoiding errors caused by assembly after separate processing, while reducing the number of connectors and improving the overall structural strength of the pin. For example, the integrally formed first pin 110 can directly fit into the mounting slot of the connector 200 without the need for additional welding or riveting processes, thereby reducing the problem of increased contact resistance caused by poor assembly; on the other hand, if the second pin body 121 and the second assembly end 122 are integrally provided, the production process can also be simplified. This design ensures that when the second pin 120 is plugged into the target socket, the integrated structure ensures mechanical uniformity during the plugging and unplugging process, reducing the risk of fracture of the split structure due to stress concentration. In addition, the one-piece second pin 120 can directly meet the design requirements of pins with a diameter greater than 8 mm, and is suitable for high-power current transmission scenarios. On the other hand, when the first assembly end 112 and the second assembly end 122 are set as one piece, a preset angle 130 can be pre-formed on the one-piece to avoid angular deviation during split assembly and ensure the spatial position accuracy of the first pin 110 and the second pin 120. This design does not require additional adjustment of the connection angle between the two, and directly achieves the angle requirement of 70 to 120 degrees through mold molding, which is particularly suitable for standardized production of regular angles such as 90 degrees. On the other hand, if the first pin 110 and the second pin 120 are set as an integral whole, the entire connector can be manufactured as a single part, completely eliminating the assembly process. This design not only significantly reduces production steps but also optimizes the bonding strength between conductive and insulating components through integrated molding processes such as overmolding. It also avoids dust and moisture accumulation in gaps caused by multi-component assembly, improving the connector's reliability in complex environments. Furthermore, all integrated solutions maintain the original mold and production process for connector 200, reducing manufacturing costs by simplifying the pin structure and facilitating large-scale production and market promotion of high-current connector inserts 100.

[0063] In order to facilitate the connection between the first pin 110 and the second pin 120, in some embodiments, the first assembly end 112 and the second assembly end 122 are plugged, riveted, clamped or screwed. Figure 2As shown, the second assembly end 122 passes through the first assembly end 112 and is fixed to the first assembly end 112 by reverse riveting, ensuring that the first assembly end 112 and the second assembly end 122 are in reliable contact and not loose. As an example, the high-current connector plug 100 is assembled by inserting two separate pins together and then riveting them to achieve a secure connection between the two separate pins. This connection will not loosen under the action of heat or external forces, effectively ensuring power transmission of the pins and effectively achieving power transmission of high-power charging modules, solving the power transmission needs of 60 kilowatts or greater power modules.

[0064] As an example, the first assembly end 112 has a cylindrical inner wall portion, and the second assembly end 122 has a cylindrical outer wall portion that matches the cylindrical inner wall portion. When the second assembly end 122 passes through the first assembly end 112, the cylindrical outer wall portion and the cylindrical inner wall portion are in close contact with each other with a maximum area. The second assembly end 122 has a pressing portion extending outside the first assembly end 112. The second assembly end 122 is fixed to the first assembly end 112 by reverse riveting through the pressing portion, so that the pin can achieve high-power current transmission through the split combined riveted edge. This design is conducive to optimizing conductive performance. The design of close contact with the cylindrical inner and outer walls with the maximum area can significantly reduce contact resistance and reduce energy loss and heat generation problems during high-current transmission. For example, when current passes through the connection interface between the first assembly end 112 and the second assembly end 122, the regular cylindrical surface fits together to form a uniform conductive path, meeting the high current transmission requirements of power modules of 60 kilowatts and above, and effectively solving the power transmission reliability problem of high-power charging modules. On the other hand, it is beneficial to improve the stability of the connection structure. The pressing part of the second assembly end 122 is fixed to the first assembly end 112 by reverse riveting. This mechanical connection method can form a high-strength rigid connection. During the riveting process, the reverse edge of the pressing part is deformed and embedded into the inner wall of the first assembly end 112, preventing the two from loosening under plugging or vibration scenarios, ensuring the long-term stability of the connection, and is especially suitable for high-power charging environments such as charging piles that require frequent plugging and unplugging. On the other hand, it is beneficial to the production process and cost advantages. The design of the split combined riveted edge does not require a complex one-piece molding mold. The first pin 110 and the second pin 120 can be processed separately and then assembled through a riveting process, reducing the mold development cost and processing difficulty. Furthermore, the cylindrical structure facilitates standardized production and accommodates pins with diameters greater than 8 mm without changing the existing production process for connector 200, facilitating the large-scale manufacturing and market promotion of high-current connector insert 100. Furthermore, this design avoids the metal fatigue or structural damage that can result from traditional bent pins. The split riveting enhances the overall mechanical strength of the pins, improving the connector's reliability under complex operating conditions.

[0065] In some embodiments, a high current connector 300 is Figure 3 and Figure 4 As shown, it includes a connection seat 200 and a high current connector plug 100 as described in any embodiment; Figure 8 and Figure 9 The first pin body 111 of the high current connector plug 100 is arranged in the connection seat 200, and the second pin body 121 of the high current connector plug 100 is arranged outside the connection seat 200 to be plugged into the target socket. For the convenience of matching use, as an example, the high current connector 300 may also include a target socket to be plugged into the second pin body 121. As an example, Figure 5 and Figure 6 As shown, the high-current connector plug 100 is detachably mounted on the connection base 200. It is understandable that, since the high-current connector plug 100 described in any embodiment is adopted, the high-current connector 300 also has the beneficial technical effects of the high-current connector plug 100, which will not be described in detail here.

[0066] The high-current connector 300 that adopts the high-current connector plug 100 of any embodiment is optimized for carrying large currents, and is therefore particularly suitable for products such as charging piles that require large currents and have high safety performance requirements. The high-current connector plug 100 does not involve changes in the shape of the traditional connection socket 200, so there is no need to add an additional mold for the connection socket 200, nor is there a need to change the production process of the connection socket 200. In some embodiments, the high-current connector 300 is a connector for a charging pile. As an example, the high-current connector 300 is a charging pile connector with a pin diameter of 8 mm. Compared with traditional straight pin connectors, the high-current connector 300 has the advantages of a smaller connector size but higher power. The 8 mm diameter pin does not need to be bent 90 degrees for use, so the high-current connector 300 does not require a bending process.

[0067] In some embodiments, a charging module for a charging pile includes the high-current connector 300 described in any embodiment. It is also understandable that, due to the use of the high-current connector 300 described in any embodiment, the charging module for the charging pile also has the beneficial technical effects of the high-current connector 300, which will not be described in detail here.

[0068] It is understood that the charging module for the charging pile may also include a target socket that plugs into the second pin body 121. As an example, the charging module for the charging pile may also include an AC-DC conversion unit, a main control unit, and a protection circuit. This design facilitates high-power transmission and compatibility. The first pin 110 and the second pin 120 of the high-current connector 300, with their preset angle 130 and cylindrical structure, can transmit power from power modules of 60 kilowatts or greater, meeting the high-power charging requirements of the charging pile. For example, the first pin body 111 contacts the current input / output terminals, and the second pin body 121 plugs into the target socket, forming a stable conductive path. This, combined with the AC-DC conversion unit, allows for efficient power conversion, making it suitable for various high-power charging scenarios. Furthermore, it facilitates space optimization and structural reliability. The preset angle 130 of 70 to 120 degrees formed by the first pin 110 and the second pin 120 enables a more compact layout of the charging module within the charging pile, reducing space requirements compared to traditional connectors and making it suitable for the narrow interior space of the charging pile. At the same time, the pin's raised structure and riveting fixation ensure a stable connection, preventing poor contact due to vibration or plugging and unplugging. Combined with the protection circuit, it further enhances charging safety. Furthermore, the integrated design and split riveting process of the high-current connector 300 eliminate the need to change the mold and production process of the connector 200, reducing the manufacturing cost of the charging pile module. Furthermore, the standardized cylindrical pin structure facilitates integration with the target socket and other modules, such as the main control unit, improving the compatibility and scaled production efficiency of the charging module, which is conducive to promoting the popularization and application of high-power charging piles.

However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
